HOLDER AND DISPENSER FOR LONGITUDINALLY DISPOSED MATERIAL Filed Feb. 24, 1964 I INVENTOR. DAVID L.. EDWARDS United States Patent 3,265,201 HQJLDER AND DISEENSER FQR LQNGETUDI- NALLY DISPOSED MATERIAL David L. Edwards, 679 S. Westlake Ave, Los Angeles, Calif. 99057 lFiied Feb. 24, 1964, Ser. No. 346,779 8 Claims. (Cl. 206-56) Generally speaking, the present invention relates to a holder and dispenser for longitudinally disposed material and, more particularly, in one exemplary form of the invention, the longitudinally disposed material may be in the form of a longitudinal applicatory member which is adapted to be applied to some surface for any of various purposes. In certain forms of the invention, the longitudinal applicatory member may etfectively comprise a marking member adapted to have its forward end forcibly applied to any suitable surface for marking same and, in this particular form of the invention, the device may be said to effectively comprise a writing instrument. However, it should be clearly noted that the invention is not limited to such a writing instrument form thereof, but may comprise a holder and dispenser for longitudinally disposed material intended for use in a variety of ways other than for writing or marking purposes, and the specific description of the exemplary form of the invention described hereinafter should be broadly construed in this way.

With the above points in mind, it is an object of the present invention to provide a novel holder and dispenser for longitudinally disposed material, comprising barrel means provided with a lengthy aperture or passage therein adapted to receive longitudinally disposed material therein and also adapted to receive a material follower and pusher means behind said longitudinally disposed material for forcible digitally-caused movement of said material follower and pusher means forwardly (but not rearwardly) whereby to feed the longitudinally disposed material toward a forwardly located material-dispensing outlet communicating with said lengthy aperture or passage in said barrel means. i

It is a further object of the present invention to provide a device of the character referred to in the preceding object, wherein the provision for allowing forward (but not rearward) movement of the material follower and pusher means against the rear end of the longitudinally disposed applicatory material in the lengthy aperture or passage is made possible by reason of the fact that the material follower and pusher means is provided with a digitallyengageable actuating portion positioned exterior of the barrel means and by reason of the fact that a one-way toothed engagement means is included and has one portion effectively connected with respect to said material follower and pusher means and has another portion effectively connected with respect to said barrel means, with said two portions being cooperable with each other for allowing said forward movement of said material follower and pusher means relative to said barrel means but being operable to positively prevent the reverse relative movement thereof, thus allowing the longitudinally disposed applicatory material to be advanced forwardly one step at a time so as to always have a forward portion projecting from the forward material-dispensing outlet of said lengthy aperture or passage of said barrel means for the convenient forcible application of the projecting end of said applicatory material to any desired surface, which will be facilitated by reason of the fact that, when force is applied to said projecting end of said applicatory material, it will not slide back into the lengthy aperture or passage in the barrel means since the one-way toothed engagement means will positively prevent this.

It is a further object of the present invention to provide a device of the character referred to hereinbefore, wherein the one-way toothed engagement means effectively comprises what might be termed linear ratchet means with a first portion thereof taking the form of inclined tooth means and with a second portion thereof taking the form of oppositely directed and inclined tooth means positioned for forcible resilient passing movement relative to each other in the forward direction of relative movement which occurs when said material follower and pusher means is moved in said forward direction toward said material-dispensing outlet, and positioned for nonpassing positive interlocking and movement-preventing engagement with respect to oppositely or rearwardly directed attempted relative movement of said material follower and pusher means away from said materialdispensing forward outlet of said lengthy aperture or passage in said barrel means.

it is a further object of the present invention to provide apparatus of the character referred to hereinbefore, wherein the barrel means is provided with longitudinal slot means and wherein said actuating portion of said material follower and pusher means is provided with a connecting part extending laterally from the exterior of said barrel means into the interior thereof and connected at said interior location to said material follower and pusher means.

It is a further object of the present invention to provide a device of the character referred to in the preceding object, wherein said first and second portions of said oneway toothed engagement means, mentioned hereinbefore, are carried respectively by said connecting part of said material follower and pusher means and by a portion of said barrel means extending along one side of said longitudinal slot means.

It is a further object of the present invention to provide a device of the character referred to hereinbefore, wherein the barrel means is provided with a laterally directed entry opening for the entry and reception of an interior material following and pushing portion of said material follower and pusher means and extending from the exterior of said barrel means into the interior of said barrel means and into communication with said lengthy aperture or passage carried within said barrel means adjacent to a material-receiving inlet portion at the rear end thereof; said barrel means being also provided with a similar laterally directed exit opening for the exit and removal of said interior material following and pushing portion of said material follower and pusher means and extending from the exterior of said barrel means into the interior of said barrel means and into communication with said lengthy aperture or passage carried within said barrel means adjacent to said material-dispensing outlet portion thereof.

It is a further object of the present invention to provide a device of the character referred to in the preceding object, wherein said material following and pushing portion of said material follower and pusher means is unsymmetrical about a transverse centrally positioned plane whereby to effectively define a forward longitudinal asymmetry and directional characteristic thereof and wherein each of said laterally directed entry and exit openings of said barrel means is similarly shaped; said longitudinal asymmetry and directional characteristic of said material following and pushing portion of said material follower and pusher means being in a predetermined forward directional relationship relative to the portion of said one-way toothed engagement means, mentioned hereinbefore as being effectively carried by said material follower and pusher means, whereby to allow only said forward movement thereof relative to said barrel means in a direction extending toward said material-dispensing outlet portion of the lengthy aperture or passage in said barrel means adapted to carry said longitudinally disposed applicatory material therein.

It is a further object of the present invention to provide a device of the character referred to herein embodying any or all of the features referred to herein, generically or specifically, individually or in combination, and which is of relatively simple, inexpensive, easy-to-use, and easy-tomanufacture construction capable of mass production at relatively low cost whereby to be conducive to widespread use thereof.

Further objects are implicit in the detailed description which follows hereinafter (which is to be considered as exemplary of, but not specifically limiting, the present invention, and said objects will be apparent to persons skilled in the art after a careful study of the detailed description which follows hereinafter.

For the purpose of clarifying the nature of the present invention, two exemplary embodiments of the invention are illustrated in the hereinbelow-described figures of the accompanying single drawing sheet and are described in detail hereinafter.

FIG. 1 is a perspective, three dimensional view illustrating one exemplary embodiment of the invention in a normal operative or use relationship with respect to a quantity of longitudinally disposed applicatory material, which is shown as taking the form of a longitudinal cylindrical applicatory member having a forward end projecting slightly from the material dispensing outlet at the forward end of the longitudinal barrel means of the exemplary form of the device illustrated. In other words, the device is shown in FIG. 1 in condition for applicatory use.

FIG. 2 is a perspective three-dimensional view of the exemplary form of the material follower and pusher means employed in the exemplary embodiment of the invention shown in FIG. 1. This view illustrates said material follower and pusher means by itself either prior to engagement with the longitudinal barrel means of FIG. 1 or after disengagement therefrom.

FIG. 3 is a longitudinal central plane sectional view, taken in the direction of the arrows 3-3 of FIG. 1. However, the material follower and pusher means and the longitudinally disposed material adapted to be pushed forwardly thereby are shown in full side elevation rather than in section in this view.

FIG. 4 is an enlarged fragmentary view, taken in the direction of the arrows 4-4 of FIG. 3, and clearly illustrates a portion of one exemplary type of one-way toothed engagement means which allows the material follower and pusher means to be advanced forwardly a step at a time by the application of digital force thereto but which positively prevents rearward retraction thereof relative to the longitudinal barrel means.

FIG. 5 is a cross-sectional view, taken in the direction of the arrows 55 of FIG. 3, and shows the longitudinal barrel means in cross section. However, the material follower and pusher means is shown in full rear elevation in this view and is shown in the act of being forwardly advanced one toothed step by the broken line fragmentary digital member shown in FIG. 5. It should be understood that the digital member may comprise the thumb or any finger of the person operating the device.

FIG. 6 is a fragmentary view, partly in section and partly in elevation, and comprises a very substantial enlargement of the fragmentary forward portion of FIG. 3 enclosed within the broken line circle designated at 6. This view is primarily for the purpose of illustrating one exemplary form of material retaining means carried by the forward end of the barrel adjacent to the material discharge outlet of the longitudinal aperture thereof and adapted to resiliently engage the side of the longitudinally disposed applicatory material whereby to prevent it from accidentally falling out of the discharge outlet by effectively retaining same within the longitudinal aperture by exerting a slight restraining force thereagainst acting in opposition to forward advancing movement of said applicatory material.

FIG. 7 is a fragmentary sectional view generally similar to FIG. 6 but illustrating a slight modification of the material retaining means of FIG. 6.

Generally speaking, the exemplary form of the invention illustrated in FIGS. 1-6 comprises a longitudinal barrel means, one form of which is generally indicated at 11, having a longitudinal aperture 12 therein extending from a rear end 13 of the longitudinal barrel means 11 to a forward end 14 thereof and having a materialreceiving inlet 15 centrally carried by said rear end 13 and having a material-dispensing outlet 16 centrally positioned in said forward end 14 of said longitudinal barrel means 11.

The exemplary first form of the invention illustrated also includes material follower and pusher means, one exemplary form of which is generally indicated at 17, as best shown in FIG. 2, which has a material following and pushing portion indicated at 18, as best shown in FIG. 2, of effective cross-sectional size and shape substantially the same as that of said longitudinal aperture 12 carried within said longitudinal barrel means 11 (although slightly smaller) whereby to be cooperable for insertion thereinto and for slidable movement along the length of said longitudinal aperture 12 in a forward direction extending from said material-receiving inlet 15 toward said material-dispensing outlet 16 thereof.

In said exemplary first form of the invention illustrated, said material follower and pusher means 17 is provided with a digitally engageable actuating portion 19 adapted to be positioned exterior of said longitudinal barrel means 11 for forcibly applied digital engagement, as is best shown in FIG. 5, whereby to forcibly advance said material follower and pusher means in the direction of the arrow indicated at 21 in FIG. 1 and whereby to correspondingly forcibly advance the longitudinally disposed material 22 positioned within the longitudinal aperture 12 in said forward direction, as indicated by the direction arrow 21 of FIG. 1.

It should be noted that, in the exemplary first form of the invention illustrated, the above-mentioned longitudinally disposed material 22 takes the form of a longitudinal cylindrical applicatory member which might comprise a wax or grease type marking member made up of a realtively rigid wax-carrying or grease-carrying matrix provided with a visibility discernable marking or coloring agent or the like disseminated therethrough. However, the applicatory member 22 may comprise various other kinds of applicatory members and is not necessarily limited to such a wax or grease pencil type of marking member in all forms of the invention.

It should be noted that, in the exemplary first form of the invention illustrated, the above-mentioned positioning of the digitally engageable actuating portion 19 of the material follower and pusher means 17 exterior of the longitudinal barrel means 11 for said forci-bily applied digital engagement, as shown in FIG. 5, is made possible by reason of the fact that said longitudinal barrel means 11 is provided with longitudinal slot means 23 extending along one side wall of the longitudinal barrel means 11 and parallel to the longitudinal axis of the aperture 12.

Also, the above-mentioned relationship is made possible by reason of the fact that the digitally engageable actuating ortion 19 is connected to the material following and pushing portion 18 of the material follower and pusher means 17 by a connecting part 24 which is relatively thin and which is adapted to extend laterally through said slot means 23 from the actuating portion 19 exterior of the longitudinal barrel means 11 into the interior of said longitudinal barrel means 11 where it communicates with said material following and pushing portion 18 positioned within the longitudinal aperture 12 within the longitudinal 5 barrel means 11. This is clearly shown in both FIGS. 3 and 5.

In order to provide for the above-mentioned forward movement only of the material follower and pusher means 17 relative to the longitudinal barrel means 11, the device includes one-way engagement means which, in the exemplary first form of the invention illustrated, is of a type comprising linear, longitudinally arranged, toothed engagement means or ratchet means, generally designated by the reference numeral 25 as best shown in FIG. 4, and which comprises first and second portions 25A and 25B, with said first portion 25A being carried by said connecting part 24 of said material follower and pusher means 17 and with said second portion 25B being carried along one edge of said longitudinal barrel means 12 defining one side of said longitudinal slot means 23 in a position for said forward-movement-allowed and rearward-movement-prevented one-way engagement of said first and second portions 25A and 25B of said oneway engagement means 25.

In other words, in the exemplary first form of the invention illustrated, said first portion 25A of said one-way engagement means 25 takes the form of a plurality of rearwardly and outwardly directed and inclined tooth means, designated by said reference numeral 25A, while said second portion 25B of said one-way engagement means 25 takes the form of a plurality of forwardly and inwardly inclined tooth means, also designated by said reference numeral 25B, with said teeth 25A and said adjacent teeth 25B being normally engaged in a manner such as that clearly shown in FIG. 4, but being adapted to allow relative forward movement of the plurality of teeth 25A carried by the material follower and pusher means 17 with respect to the other plurality of teeth 25B carried by the edge of the slot means 23 of the longitudinal barrel means 11 because of the resiliently defiectable nature of the material forming same, which is preferably a defiectable plastic material adapted to allow such forward movement of the first plurality of teeth 25A relative to the second plurality of teeth 25B. However, any material deflectable enough for this purpose may be employed for either or both sets of teeth 25A and/ or 25B.

While the one-way engagement means 25 of the first form of the invention just described provides a very effective arrangement for allowing relative forward movement of the material follower and pusher means 17 in the for ward direction indicated by the directional arrow 21 of FIG. 1, it will readily be understood that it positively prevents oppositely directed or relative rearward movement of said material follower and pusher means 17 with r respect to the longitudinal barrel means 117 This, of course, means that force can be applied to the forward or tip end 26 of the longitudinally disposed applicatory material 22 during a writing operation, or other type of applicatory operation, since the rear end 27 of said applicatory material 22 will be solidly and firmly held in position by the material following and pushing portion 18 of the material follower and pusher means 17, which will be held in said position by the positive backward movement preventing one-way engagement means 25.

Various means may be employed for placing the material following and pushing portion 18 of the material follower and pusher means 17 against the rear end 27 of the applicatory material 22. Also, various means may be employed for repositioning the material follower and pusher means 17 at the initial or starting position after it has been moved forwardly a step at a time until the applicatory material 22 has been abraded away and used up at the front end 26 thereof and requires replacement or replenishment. In certain cases, this may be made possible by using the material-receiving inlet 15 and the material-dispensing outlet 16 and by having the longitudinal slot means 23 extending therebetween from the 5 rear end 13 of the longitudinal barrel means 11 to the front end 14 thereof.

However, in the exemplary first form of the invention illustrated, a slightly different arrangement is provided and comprises the inclusion of a laterally directed entry opening, indicated generally at 28, and a laterally directed exit opening, indicated generally at 29, positioned respectively adjacent to the material-receiving inlet 15 of the longitudinal barrel means 11 and adjacent to the material-dispensing outlet 16 of the longitudinal barrel means 11 and, in each case, communicating the exterior of the barrel means with the longitudinal aperture or passage 12 comprising the hollow interior thereof.

The arrangement is such that the material following and pushing portion 18 of the material follower and pusher means 17 can be laterally inserted through the entry opening 28 into the longitudinal aperture or passage 12 immediately behind the read end 27 of the longitudinally disposed applicatory material 22, which has been previously inserted through the inlet 15 to a degree such as to have its rear end 27 positioned forwardly of said entry opening 28. Then, after the previously described step-by-step forward advancing movement of the longitudinally disposed applicatory material 22 to an extent such that the rear end 27 thereof lies just forwardly of said exit opening 29, the material following and pushing portion 18 of the material follower and pusher means 17 can be laterally removed from the longitudinal aperture or passage 12 by way of the exit opening 29. Then a new quantity of longitudinally disposed applicatory material, similar to that shown at 22, can be inserted through the rear inlet 15 to an extent such as to pass the rear entry opening 28, and the material following and pushing portion 18 of the material follower and pusher means 17 can again be laterally inserted through the rear positioned entry opening 28 into a position behind and in abutment with the rear end 27 of the longitudinally disposed applicatory material 22 for repetition of the previously directed forward step-by-step feeding action of the material follower and pusher means 17 and the longitudinally disposed applicatory material 22.

Incidentally, it should be noted that the positioning of the entry and exit apertures 29 may be varied from the arrangement illustrated in the first form of the invention shown in FIGS. l-6. For example, said openings may be positioned nearer to the rear and front ends 13 and 14 of the longitudinal barrel means 11, if desired, or may be otherwise modified within the broad spirit and scope of the present invention.

In the exemplary form of the invention illustrated, means is provided for preventing an incorrect backward positioning of the material following and pushing portion 18 of the material follower and pusher means 17 within the longitudinal aperture or passage 12. This will, of course, prevent the improper positioning of the teeth 25A of the one-way engagement means 25 and, in the exemplary first form of the invention illustrated, this desirable objective is accomplished by reason of the fact that the material following and pushing portion 18 is unsymmetrical about a transverse centrally positioned plane whereby to effectively define a forward longitudinal asymmetry and directional characteristic thereof, which is effectively duplicated by similar shaping of the entry and exit openings 28 and 29.

It will be noted that said longitudinal asymmetry and directional characteristic of the material following and pushing portion 18 is provided by having a forward cylindrical portion 18F and a rear cylindrical portion 18R which are of different lengths and which correspond exactly to corresponding cylindrical cutout portions 28F and 23R of the entry opening 28, and 29F and 29R of the exit opening 29. It is obvious that this makes it possible to insert the material following and pushing portion 18 through the entry opening 28 in one direction only,

this being a forward direction such as that indicated by the directional arrow 21 of FIG. 1 and being in a predetermined relationship with respect to the rearwardly and outwardly directed and inclined tooth means 25A comprising the first portion of the one-way engagement means 25. Said forward longitudinal asymmetry and directional characteristic is further indicated by reason of the fact that the digitally engageable actuating portion 19 has a forward arrow-like end portion 31 and simulates in appearance a directional arrow, thus clearly indicating the proper direction in which to hold the material follower and pusher means 17 when it is inserted through the entry opening 28 into the longitudinal aperture or passage 12 behind the longitudinally disposed applicatory material 22.

FIG. 6 merely illustrates one exemplary type of resilient retaining means, indicated at 32, and comprising an inwardly directed resiliently outwardly deflectable projection carried by the forward end 14 of the longitudinal barrel means 11 in a position such that it will forcibly resiliently engage the side of the longitudinally disposed applicatory material 22 as it is forced forwardly out of the outlet 16. Obviously, this will act as a retaining means and/or a restraining means preventing the applicatory material 22 from accidentally and unintentionally falling out of said outlet 16, but will allow it to be forcibly advanced through said outlet 16 by forward step-by-step movement of the material follower and pusher means 17 in the manner described in detail hereinbefore.

FIG. 7 illustrates a slight modification of the retaining means 32 best shown in FIG. 6, and all portions of this modification of the invention are indicated by reference numerals similar to those of the first form of the invention illustrated in FIGS. 1-6 and described in detail hereinbefore, but primed, however, in FIG. 7.

It will be noted that the only difference of this modification of the invention is the fact that the retaining means 32' comprises a detent projection formed at the forward end of the longitudinal aperture 12' and extends directly inwardly into the path of travel of the longitudinally disposed applicatory material shown fragmentarily at 22 whereby to retain and restrain same in a manner generally similar to that described hereinbefore, although it may actually slightly press into and slightly deform one side surface thereof as it is forcibly extruded forward by reason of operation of a material follower and pusher means, such as shown at 17 in the first form of the invention illustrated in FIGS. 1-6.

It should be noted that the exemplary first form of the invention illustrated in FIGS. 1-6 is slightly distorted from its normal appearance in that it is shown somewhat shorter and somewhat wider than would normally be the case in most physical embodiments thereof. This is done for reasons of drawing clarity and is not to be construed as limiting the invention thereto.

It should be understood that the figures and the specific description thereof set forth in this application are for the purpose of illustrating the present invention and are not to be construed as limiting the present invention to the precise and detailed specific structure shown in the figures and specifically described hereinbefore. Rather, the real invention is intended to include substantially equivalent constructions embodying the basic teachings and inventive concept of the present invention.
