I In 42 4/2? Patented May 1, 1951 UNITED STATES PATENT OFFICE EJECTOR-TYPE HOLDER FOR TONGUE BLADES The present invention relates to a novel and improved ejector-type holder and dispenser which is especially, but not necessarily, adapted for use in the oflice of a physician, a hospital examination room, or the like, the same being expressly made and designed to conveniently and efiectively contain'and dispense so-called tongue blades, one at a time.
An object of the invention, outstanding in degree, is to provide a holder and dispenser for tongue blades which is essentially made of plastic and nicely shaped and colored to appeal to the eye of the observer, the same being highly desirable for use because of the hygienic conveniences and time saving facilities incorporated therein.
More specifically, in carrying out the principles of the invention, I have evolved and produced a wall-type tongue blade dispenser, wherein the tongue blades are always within convenient reach of the examiner, are hygienically stored in stacked relation for convenience, and wherein the operation is such that it may be achieved with one hand, the only hand which touches the blade as it is ejected from the blade holding casing. I
Another object of the invention is to provide a blade holding dispenser for use in examining rooms, wherein the blade may be readily ejected and projected for use almost without looking, a device which is attractive in appearance, the hygienic factors of which are appreciated by discreet patients, a structure whose use saves many steps and considerable time, protects the encased blades from dust, dirt and deleterious matter and insects, and is far more eflicient than the usual lidded jars which are commonly used in present- :day practices.
An equally important aim is to provide a structure of the kind under advisement, which is characterized, on the one hand, by a unique suitably colored and transparent casing, the casin being closed on all sides except the back, being such as to conform to the shape of the tongue blades which are stored therein, and thus, serving to expedite the step of systematically and aptly charging or loading the casing with blades in stacked relation, in a manner to avoid cooking and jamming.
Another objective is to provide a casing of the aforementioned type with a novel wall bracket or fixture on which the casing is slidably hung, coacting elements existing between the bracket and casing, whereby the latter may be conveniently locked in place by an existing part of the projectible and retractible ejector-slide,
Other objects and advantages will become more readily apparent from the following description and the accompanying illustrative drawings.

Figure 9 is a perspective view of the projectible and retractible ejector-slide.
Figure 10 is a rear end elevation of the casin detached from the wall bracket.
Referring now to the drawings by distinguish.- ing reference characters, the wall or other stationary support is denoted by the reference character A, the wall hanger bracket or fixture by the reference character B, and the blade holder and dispenser unit by the reference character C.
A comparatively major part, a subdivision of the unit C, is the especially constructed ejector-slide or plate D (see Figure 9).
Attention is directed first to the hanger bracket or fixture B, which is designed to conveniently suspend the casin unit C on a wall or other support. This bracket or fixture is preferably made of ivory or equivalent material and is shown-to advantage in Figure 8. Reference being had to the latter figure, it will be noted that the bracket comprises 9, substantially rectangular plate l2, Whose vertical edge portions are pro vided with channel-shaped guide tracks l3, disposed in parallelism along said edges. The numerals l4 designate horizontal check webs which will be later described. At the bottom of the plate is a horizontal lip or lug [5 which may be conveniently referred to as a detent. This is in spaced relation below the lower ends of a pair of parallel guide flanges I 5. These flanges iii are duplicates and are attached to the plate and extend at rightangles from the plate, and are located inwardly of and are in spaced parallelism with the guide channels or track 13. The lower ends of said flanges constitute additional shoulders or detents I! which servein-amannerrto be later described. Between the flanges l6 and also attached to the plate is a vertically or 1ongitudinally extending reinforcing rib I3 having reinforced holes I9 to accommodate screws ,or equivalent fasteners 20 which are, in practice, screwed into the wall,A. It will be notedthat the channel guides l3-are open at their upper -ends-and closed at their lower ends. The closed lowerends are substantially level with the detent 15. Also, the detent' I 5 is-of a width corresponding to the widths of the flangeslfiand the'vertical edge portions of the flanges l6 extend to planes slightly beyond the adjacent channel guides 13. The closed lower ends of said channels l3 and coactingdetent means l5 coordinate in providing anefiective closurewhen joined with the hereinafter described casing C :and ejector slide D.
The casing 'C is of substantially rectangular form and is made of suitably colored substantially transparent plastic. It is slightly narrower at the outward vertical or front portion and, consequently, slightly wider at the rear attachable portion, as brought out in perspective in "Figure 1, and the narrower front corresponds to the rounded end portions of the'customary wooden or :equivalent tongue depressor blades :"2I. 'Generallyvisualize'd, thecasing is closed on all but one side, namely, the vertical side or end which permitsconvenient insertion and removal of tongue blades, that is, when the casing is detached from the Wall bracket. Said casing in- :cludes a horizontal bottom wall 22, a parallel horizontal top wall 23, duplicate side walls 2 1 and a vertical front end wall 25. The latter is rounded in cross-section to correspond to the rounded end configuration-of one of the blades -21. The lower end of the front wall 25 is provided with a discharge slot 26. The bottom 22, -.as shown in Figure '5,has-a guide-slot 2'1, which opens into said notch or slot '26 and the inner .end of the slot "21, the crotch portion, constitutes a stop 28. The numeral '29 designates a reinforcing rib on the underside of said bottom 22. The numerals 30 designate outstanding keying and assembling ribs on walls '24 which are slidable in the channel guide-ways I 3. These keys 30 are approximately of the vertical .lengths shown in side view in Figure 2. The numerals 31 at the upper end portions of the ribs denote stop'lugs which, when the casing C is seated properly in the bracket, rest on the upper end portions of the bracket and virtually close the :channels.
The numeral 32 designates a hood-like cover for the discharge opening 26, and this is of arouate form and conforms to the curvature of the front end wall 22 and is sufiicient to normally .drop down and close the discharge opening. It is provided with arms 33 which have studs 34 which snap into suitable accommodation holes in the sides of the casing. This arrangement of a coacting tongue blade.

.against the follower lug 43.
permits the cover to have the desired hinge action. Also, the plastic material is sufficiently pliant to permit the arms 33 to be grasped between the users fingers and spread apart to either dislodge the studs 34 or to snap the same into the holes provided therefor in the sides. The numeral 35 is simply a finger-grip carried by the hood. The numeral 36 is merely an ornament left by the molding step and is of no special purpose.
Coming now to the unusually constructed ejector slide, this comprises an elongated plate 31 (see'figure "9) having a rounded outer end portion 38 which conforms somewhat to the shape andsize of a conventional-type depressor or tongue blade 2!. The numeral 39 designates a trigger or finger-grip which has a finger notch 40 and which is slidable in the kerf or slot 21, 'as brought out in Figure 5. The numeral 4! designates a return sprin which is a simple coiled spring having one end attached to the trigger :and the other end attached to the reinforcing rib 29. The numeral 42 designates a stop or abutment on the trigger which comes against the stop 28 to limit the inward sliding movement of the ejector slide. On'the inner end of the slide is an upstanding lug 43 which constitutes a follower which serves to engage the adjacent end portion of the tongue blade to project same. The :numeral 14 is -a transverse cross-member which constitutes a-stop for the outward 'orforward movement of the ejector slide and which comes into contactwith guide flanges or ribs and -46, as shown in dotted lines in Figure 3. These guide ribs are rigidly mounted on the inner surfaces of-the side walls 24 of the casing and are at a level above the bottom of the casing so that the coacting portion of the slide slides at the bottom beneath them, in an obvious man The guide ribs 45 and 45 also serve as ledges and also serve to keep the blades 2| 'level and lined up with the discharge openin 26 in the casing. What is more, the desired levelling result is furthered by the provision of the auxiliary riser or abutment 41. It will be seen that the two risers A l and 41, together, form a sort of FT-shaped rest for the adjacent end portion The numeral 43'is the follower which causes the blade to move out witht e ejector slide when the trigger of the latter is actuated in an obvious manner, as shown Without the guide ribs 45 and G6, and the risers 44 and 41, the tongue :blade might tilt toward one longitudinal edge or the other, and thus jam the expected one-byone dispensing result.
It will be understood that normally the hoodlike closure 32 is down, as seen in Figure 1. When, however, the ejector is operated and the forward curvate end 38 comes into pressure contact with the cover, the cover is'lifted up and the blade is allowed to be projected for convenient grasping, all as shown realistically in Figure 5.
It will'be noted, in considering the construction, that the ejector slide plate 3'! is approximately the same length as one of the tongue blades 2!. :being slightly longer so that one end of the blade rests against the follower lug 33, while the other end of the blade somewhat matches the correspondingly shaped end of the plate, the end 38. One half portion of the lowermost blade, the one to be dispensed, rests on the risers M and t1, and The forward half portion of the same blade rests upon the top surfaces of the guide flanges 45 and 46. Thus, when you have one end of the blade resting on flanges 45 and 46, the other end portion is on the risers 44 and 41 with the lateral end abutting the follower 43. This means that when the ejector is in there is a space between the lowermost blade, the intermediate portion and the underlying bottom of the casing, the bottom 22. By thus suspending the blade so that it is not in direct frictional contact with the plate 31, the blade is in a satisfactory position to be ejected with requisite smoothness. Also, there is a minimum of contact between the blade 2! and said parts 43, 44, 41 and 45 and 45 than would be the case if the blade were resting throughout its entire area on the plate 31. This makes for smooth operation of the ejector-slide, obviously.
Another point to be made clear is the fact that the aforementioned vertical guide flanges l6, part of the bracket B, primarily serve to define between themselves a guide-way and, therefore, the adjacent rounded end portions of the tongue blades 2| in the stack, fit down in the space between the flanges I6. This facilitates properly racking and uniformly stacking the blades in the casing and with inner ends against the bracket to facilitate their dropping down slowly for stepby-step dispensing, and this accomplishment is exaggerated in the dotted line showing of the right-hand end portions of the blades fitting between the flanges [6 in Figure '7. We again see this accomplishment disclosed in Figure 1.
It is also highly desirable that the ejector-slide D serve not only as a vending device for the stack of blades, but also as a ways and means of latching or locking the casing unit on the bracket B. This is done by permitting the inner spring retracted end portion of said ejector-slide to fit releasably between the detents or shoulders l5 and F1. Or, to put it otherwise, the detents I 5 and IT with the space existing between same, provide a sort of a keeper pocket and the adjacent end portion of the plate 31 including the lug 43 and riser 44 fit into this pocket or space. The spring holds the parts I5, I! and 31 thus assembled, and the ejector-slide becomes a retaining latch and latches the casing C on the bracket B. It means, too, that before the casing may be lifted and slipped up and off of the bracket means, the "latch D must be released. Assuming then that the casing is, for instance, in the assembled position seen in Figures 1 and 4, and it is desired to lift the casing up for re-loading or recharging it with new blades, before this can be done, it will be necessary to catch ahold of the trigger 4!] and to slide the plate 31 slightly outward until the parts 43 and 4 3 are withdrawn from the space and disengaged from the detents or shoulders l5 and I]. Now, the casing is unlatched and may be lifted up and removed, as shown in the partly lifted position in Figure 2.
It is believed to be novel to slide the ribs or flanges 3!! up and down in the channel-like portions l3, to provide a guide for the stack of blades between the flanges l6 and to utilize the plate 3'! as a latch for interlocking coaction with the detents l5 and I1 (see Figures 3 and 7 particularly).
I would stress the fact that the upper ends of the so-called guide channels is are cut away to provide clearance notches and to facilitate placing the lower ends of the ribs 3!] into the channels to facilitate attaching the casing C to the bracket B. It will be noted that the flanges or ribs 30 range only a little over one half the vertical height of the casing. Also, I stress the fact that it is possible to place a complete package (not shown) of blades into the open side of the casing without touching same by hand. The ends of the blades which are adjacent to the bracket B are nicely sustained between the stabilizing flanges I6 and are not apt to get out of place. The major portion of each blade just before it is dispensed is supported on the ledge flanges or ribs 45 and 46 and only one end portion of a relatively small area, of the blade, actually bears upon the slide D. In fact, this does not bear directly on plate 31 but instead bears on the elements 44 and ll of the so-called T-shaped riser. The flanges G5 and 46 are in the proper plane in relation to the bottom of the casing, the ejector slide and also the hooded discharge opening 26 to make sure that all parts work in proper progression and relationship.
A careful consideration of the foregoing description in conjunction with the invention as illustrated in the drawings will enable the reader to obtain a clear understanding and impression of the alleged features of merit and novelty suflicient to clarify the construction of the invention as hereinafter claimed.
