present invention is designed as an addition to the cotton wedding machine shown and described in Patent No. 2,171,572, issued Septemher 5., 1939, although the special featuresof the present invention are capable of employment in other types of machines designed for asimilar purpose. .The cotton Wadding machine of the patentaoove referred to is designedto feed forwarda continuous rope 10'! Strand of fibrous material, preferably cotton, and to cut. therefrom charges of suitable length for insertion into the mouth of a bottle or other container of the character commonly .employed for the retention of tablets, pills, or other :materials of a similar nature,.and wherein it isdesirable to wadthe mouth of the bottle to .prevent rattling.or contamination of the contents. A

The machine of the patent aforesaid has proven highly effective for use in the'wadding of bottles which are not abruptly'shouldered below the neckbut in cases where the bottle is thus shouldered, it has been found desirable to modify the structure of the machine in such a way as to make provision for the lateral distention of the wadding beneath the shoulders of the bottle in order to more firmlycompact'thefcontents where bottles of this character are employed, and the present invention is designed as'an addition or attachment for the purpose of thus spreading the wedding under the conditions named. I

The method here involved consists broadly in the slitting cf the leading end of a-cotton wad prior to its insertion into a bottle and in'guiding and to the action of a separator blade Within the tube which serves to maintain the slitted ends of the cotton'charge in separate relationduring the and directing the slitted end during the inserting operation, so that divided legs or sections of the Wad will tend to spread laterally during the thrust which inserts the charge into-thebottle thereby causing the waddingsections t o spread beneath the bottle shoulders and thus morecompletely fill the empty space above the contents of the bottle. 7 y

In the machine here illustrated, asan exemplification of the present invention,the' forward end of a continuous rope of cotton or the hire is fed downwardly by rollers and forced into the end of a-tube from which the charge is ultimately ejected into the bottle. During the 'in'feeding of the cotton into the tube, the forward end of the charge'is slit end-wise by a cutterand at the same time the upper end of the charge is cutfree from be wadded are fed inwardly through a'guide track the continuous rope thuscernple't'ingthe'insertion V of a charge into thetube in preparation" for its Thereafter, while the tube isin register :With the bottlemouth,

the charge issub'jec'ted to the'thru'stof a'plunger 'in any suitable manner.

bottle charging operation. These operationsare all performed in a timed sequential series so that the bottles in processional relation will be brought to the charging point at the proper time to register with the loaded'tube to receive the wad ejected therefrom. p i

Further objects and details will appear from a description of the invention inconjunction with the accompanying drawings, wherein-- Figure 1 is a perspective view of a mac-hin which, save for the special features of'the present invention, is substantially similar-to that shown and described in full detail in-the patent :previously referred to;

Save for the .specialieatures' presently to be described in full detail, the machinexin the'form shown'is substantially the same as that 'fully described in the patent referred'to, so that it is not here deemed necessary to describe infull detail the entire train of operating connections where by'power is transmitted to the various operating mechanisms. The machineas a whole comprises a base housing it supported upon legs H and presenting its upper surface'in the form of 'a table top [2 which supports the externally located portions of the mechanism. The bottlesto 13 which standsain'elev'ated relation above the upper tdrn of endless conveyor belt lg-td'riven guide track I3 stands in adjacent relationito.:-a

carrier disk l5 which isrotated? in fcounte'rclockrwise direction by any; suitable mechanism: .The

carrier disk isnprovided 1 in its Uperiphery' .with a The inner end iiof the.

series of notches it which, in the present instance, are six in number and equally spaced, and each of proper dimensions to receive a bottle of the size to be wadded. The bottles are fed inwardly on the inner side on Fig. 1 and are released from the machine and carried onwardly after wadding by a conveyor belt I! located in adjacent relation to guide track l8 similar, in all respects, to guide track [3.

The continuous strand of cotton C lies coiled within a container I9, and its leading end is carried through a guide arm and thence between upper feed rolls 2| and 22 and lower feed rolls 23 and 24, similar in all respects to those shown in the patent aforesaid. The lower feed rolls project through the wall of a fixed tubular guide 25 which stands in position to successively register with each of a series of loading tubes 25 which, in the present case, are six in number, and clamped within and carried by the arms of a star wheel carrier 21 corresponding to the rotating head 36 of the patent, which star wheel is carried by and rotatable with a vertical shaft 28 corresponding to the shaft 31 of the patent.

The upper ends of the loading tubes 26 stand at an elevation which affords relatively close clearance for the intrusion of the razor sharp edge of a rapidly rotating cutter blade 29, the major portion of which is located within a housing 30, cut away on its inner side to expose the cutter blade and permit it to swing into the clearance space between the fixed guide tube 25 and a charging tube 26. The cutter blade is fixed upon a vertical shaft 3| which is journaled through the housing and carries a grooved pulley 32 at its by a pulley 34 on the shaft of a motor 35 supported from a bracket arm 36, or in any other suitable manner. The housing 30 is provided with an outwardly extending arm 31 which is mounted upon a fixedly positioned pivot 38, and the outer end of the arm 31 carries a roller 39 which is engaged by a cam 40 on a cam shaft 4| in reduced train with the motor, so that at recurrent intervals the high point on the cam will swing the cutting edge of the knife blade into the space through which the cotton strand is being fed for the purpose of severing a charge of cotton of the required length to constitute a charge. The pivotal mounting 38 is in concentric relation with the motor shaft so that the inswinging of the cutter will not disturb the belt driving relationship of the parts, the knife being driven at a very high rate of speed and maintained in razor-edged condition to cleanly cut through the cotton strand. The above described features are substantially identical with those described in the patent aforesaid, so that further description is deemed unnecessary.

The cross cutting blade coacts with a slitting rotary blade 42 which constitutes one'of the principal features of the present invention. The slitting blade is mounted upon the inner end of a horizontal shaft 43 journaled through a swivelly mounted swinging bracket arm 44, which isin train with a vertical driving shaft 45 journaled through the bracket arm 36, and carrying a grooved pulley 46 at its lower end. The grooved pulley mounts a belt 41 which passes around a driving pulley 48 also on the motor-shaft so that the operation of the motor will simultaneously impart'a high speed of rotation both to the cross cutter blade and the slitting blade.

The housing 39, as-shown, is provided with a depending stud 49 which registers with a cam lower end. The pulley mounts a belt 33 driven 4 track 50 so configured that as the housing swings inwardly to advance the cross cutting blade toward the cotton strand, the slitting blade will first be swung inwardly sufficiently to cause its cutting edge to pass through a vertical slot 5| in the proximate wall of the charging tube currently in register therewith, as best illustrated in Figs. 4, 5 and 6, thereby preliminarily slitting the leading portion of a cotton charge before the same is out free from the cotton strand. The charging tubes of a single set are all of the same formation and of a size to coact with the bottles to be wadded, and it will be understood that sets of charging tubes of varying dimensions may be substituted for one another to fit bottles of different sizes as occasion may require.

In the form shown each charging tube is throated at its upper end 52 and the slot 5| is of sufficient Width to provide the clearance necessary to permit the slitting blade to swing inwardly to a sufficient extent to slit through the advancing end of the cotton charge in order to divide the lower portion thereof into separated legs or sections without, however, slitting through the upper end of the charge which preferably remains intact.

In order to permit the employment of a relatively small slitting blade and to provide for its inswinging to the desired extent, the slot 5| is recessed laterally at the points 53 which permits the slitter shaft 43 to swing inwardly to the extent indicated in Fig. 4, and in order to more thoroughly compress the cotton toward the cutting edge, an inwardly projecting boss or hump 54 is provided in the opposite Wall of the tube which is provided with a vertical slot 55 through its crest which permits the edge of the blade to enter slightly, and thereby insure a clean and complete cut through the cotton wad. It is necessary to time the inward swing of the slitting blade so that it will advance to cutting position while the cotton strand is being fed forwardly under the thrust of the feed rolls and before the cessation of this feeding movement occurs in preparation for the severing of a charge by the cross cutting blade, and the cam track 59 is con figured to time these movements accordingly. Thus in Fig. 4 I have shown the slitter blade thrust inwardly to attack the leading end of the cotton strand While still under the feeding action of the rolls 23 and 24. In Fig. 5 I have illustrated the recession of the slitter blade in preparation for the advance of the edge of the cross cutter blade 29, which is shown in said figure, and it will there be noted that the upperend of the wad remains intact and in condition for its final insertion into the bottle after the loaded charging tube has been moved away from the slitting position and brought into register with the mouth of the bottle. 7

In order to hold the divided sections of the cotton wad in separated relation both before and during the bottle wadding operation, I have provided a separator blade 56 of thin metal, and preferably of segmental shape, which is pivoted at its tapered upper end upon a pintle 5'! surrounded by a light spring 58 which normally maintains the separator blade in the inthrust position shown in Fig. 4, and wherein it traverses oppositely disposed slots 59 and 60 in the walls ofthe tube. The inner acting edge SI of the separator blade is concavely rounded and during the advance of the botton strand, and the slitting thereof, the separator blade will occupy the inthrust position with its acting edge in line with *the edge of the blade, sothat as the charge is permit the uncut portion of the cotton charge toslip'by. a

The lower end 63 of the tube is preferably tapered somewhat which imposes a light friction against the outer faces of the separated cotton sections as the wad is being driven through the contracted end of the tube, and the friction thus developed tends slightly to retard the passage of the contracted outer face portions of the sections and to cause'the same to curl or spread outwardly toward the shoulders of the bottle which is properly'positioned to thus permit the separated and outwardly distended ends of the wad to be forced back under the shoulders. The flaring or distention of the separated ends of the wad thus occasioned is due to the fact that the Wad, instead of being integral throughout is divided and thus capable of separating under the combined action of the separator blade and the curling back occasioned by the frictional contact of the cotton with the restricted discharge opening from the tube. It isthus unnecessary'to provide me chanical spreader means which enter the mouth of the bottle and operate from within to spread the cotton during its insertion into the bottle. The employment of such a means introduces an unnecessary complication in the action of the machine, and its use is restricted to bottles having a neoksuilicientl short and broad to permit the .mechanicalspreaders to enter thereinto.

Inthe case of the present invention the force employed for injecting the wad into the bottle is afforded entirely by the longitudinal thrust of the plunger operating under the conditions heretofore described. Although for most purposes it is desirable .to limit the slitting of the cotton wad t the lower portion, and to maintain the upper end intact, itis not essential in all cases that this condition be maintained since the present method of introducing a divided wad'from a tube into the character here described, will tend to separate and flare outwardly under the thrust of a plunger and to back into the space below the shoulders of a bottle, so that in its broader aspects the invention is not confined to the useof special mechanism hereinbefore described for slitting and separating the waddin charges. a

In the machine in the form shown, I have mounted charging tubes on the arms of the star wheel carrier 2'; which is fast upon the shaft 28, which also mounts the carrier disk if) for the bottles. These parts operate in unison so that as a bottle is introducedinto one of the notches iii in the carrier disk, it will come into register with one of the char ing tubes and will be intermittently advanced therewith, first to a position immediately below the plunger 62 which drives the cotton wad into the bottle, and thereafter in position to receive the thrust of a supplementary plunger 64 which'it is desirable to employ in order to prevent the lodgment of any stray whisps of cotton around the mouth of the bottle which might later interfere with the bottle capping operation and to more effectively seat the wad down on the contents of the bottle. Both plungers operate in unisonand are connected to a'slidably mounted head platetfi operated by a link 66 and a leverE'i, which in turn is oscillated by a thrust bar 68 corresponding to the parts 88 and 81 of the patent aforesaid. 'The means for timing'the reciprocation of the *plungersare in all respects similar to those described in the patent, so that detailed description ishere deemed unnecessary.

In view of the fact that the carrier disk in the form shown is provided with six notches for receiving bottles, and of thefurther fact that six charging tubes are carried by the machine, each of which must momentarilystop to receive and sever a charge from the cotton strand while preceding tubes stand in'registerwiththe plungers during an interval of rest, provision is made for the rotation of the shaft 28 which mounts these to the 'starwheel by a roller I3 carriedby a plate M keyed on a constantly power driven shaft 15.

The spur gear 12 meshes with a larger spur gear T6 on th shaft 28, the ratio being such that one rotation of the driving spur gear 12 will impart two-thirds of a rotation to the driven spur gear 76. The ratio thus provided insures that during a complete rotation of the carrier'disk it will be stopped six times, so that three of the tubes will simultaneously stand in coacting relation with the charging and discharging mechanisms shown. That is to say, the most advanced tube'of the group of three will be in position to receive the thrust of the supplemental plunger '64, while the second tube is receiving the discharging thrust of the plunger 62, and the first tube of the group is receiving a charge from the continuous strand.

It will be understood, however, that all of these mechanical details may be changed or modified without departing from the spirit of the invention, and that insofar as the bottle feeding features are concerned it is necessary only that the bottles stand in register with the tubes during the plunger operations since the tube charging operation'need .not be performed with a bottle in register.

- Operation 7 The operation may be briefly described as follows: A continuousstrand of cotton or equivalent wadding material is drawn forward from th receptacle I9 by the pull of power driven feed'rollers :23 and 24, which serve to advance the leading end of the strand and thrust the same into the mouth of a tube which, during this interval, will stand stationary and in regster with the feed rollers. After the desired length of wadding has been fed into the tube, the swiftly rotating cutter blade 29 will swing inwardly under the action of the cam 40.. However, before the cross cutting blade severs the strand the inswing of the casing 30 will advance the slitter blade 42, the rapidly rotating edge of which will b projected inwardly through the slot in the tube to slit the still advancing end of the strand before the cross cutting blade severs the charge therefrom. This sequence of operations is well illustrated in Figs. 4 and 5 from which it will be observed that the slitter blade has assumed its cutting position while the feed rollers 23 and 24 are still rotating, as indicated by the arrows. Fig. 5 indicates the position assumed by the parts at the instant the cross cutter blade reaches its severing position from which it will be noted, by the absence of arrows, that the rotation of the rollers has stopped and that the slitter blade has retreated to, its outermost position. Fig. 5 illustrates the position of the parts at the conclusion of the charging operation, and immediately thereafter the Geneva movement will impart rotation to the star wheel tube carrier 21 and the bottle feeding carrier disk I5 to advance the loaded tube with the bottle in register to a position immediately below the first plunger 62. Immediately thereafter the plunger will descend, as in Fig. 6, which forces down the charge toward and into the bottle. The separator blade 56 during the slitting and cross cutting operations, illustrated in Figs. 4 and 5, will occupy the inthrust position under the light tension of the spring 58, but during the descent of the plunger 62 the separator blade will yield to :permit the passage of the uncut upper end of the charge as the lower divided end is being forced into the bottle.

The reduced discharge end 63 of the tube will increase the friction against the outer faces of the divided wadding, and this will have the effect of retarding the advance of the outer faces as compared with the interior of the charge which causes the legs or divisions of the same to diverge under the thrust of the plunger. and this tendency to diverge will be augmented by the diversion of the separator blade, so that as the slit end of the wadding charge is projected into the bottle the separated ends, coming into contact with the contents of the bottle, will flow under the shoulders and fill the space in the upper part of the bottle.

I am aware of the fact that even without the separator blade, the frictional retarding of the r outer faces of the slit wadding. when subjected to a thrust from behind, will tend to spread the legs or divisions of the wadding charge to a substantial degree which may be satisfactory in certain cases, although where a bottle is heavily shouldered it is desirable to provide some kind of a separator which will serve to prevent the inner faces of the slit wadding sections from contact- .ing one another during a considerable portion of the discharging period, and I therefore consider the separator to be a desirable, although not indispensable, feature of the present invention. Furthermore, the presence of such a separator which is interposed between the divided sections of the wadding causes the inner surfaces to slip smoothly along the faces of the separator, so that the inner surfaces will be somewhat compacted by this action which reduces the tendency to intermesh after the leading end of the charge has entered the mouth of the bottle and escaped from further contact with the separator.

I am also aware that it may not be necessary in all cases to contract the discharge end of the charging tube since a tube of uniform diameter, receiving a charge of proper thickness, will 8 necessarily exert a certain amount of friction on the external surfaces with a resultant tendency to curl back or deflect, though for most purposes I have found that a terminal restriction with augmented friction at the point of discharge is most effective in imparting a deflecting or spreading action to the divided charge. It will be understood, however, that the increase in friction may be obtained by slightly roughening the inner surface of the tube rather than by contracting its diameter, and that development of such a frictional effect rather than the employment of specific means for attaining it is regarded as the feature of importance, insofar as concerns the method here involved.

I am also aware of the fact that although it is desirable in most cases to restrict the slitting of the charge and to leave the rear or head intact which facilitates easy removal ofthe charge from the bottle, nevertheless I have in mind the fact that the charge may, if desired, be slit and divided from end to end without substantial modification in the resultant action involved in introducing the charge into a bottle. Substantially the same result will attend the introduction of charges which are derived from separate strands individually fed to a point of convergence and introduced into the charging tube as a single charge and thereafter ejected in the manner heretofore described.

It will thereforebe understood that numerous modifications in detail may be introduced and that the essence of the present invention consists in the employment of a charge which is divided or slitted at its forward end and ejected from behind while under the confinement of the surrounding tube and under conditions which will tend to cause the legs or divisions of the charge to separate and spread under the shoulders of a bottle or similar receptacle which renders unnecessary the use of special mechanism designed to be inthrust into the mouth of the bottle for the purpose of positively spreading the wadding. By the employment of a slit wadding subjected to an endwise thrust from the rear under the conditions here described, the use of such spreading devices, with attendant complications is avoided, the wadding operation is rendered more uniform and satisfactory, and limitations due to the shapin of the bottle mouth are avoided, since the present method is one which may be successfully employed in the introduction of wadding charges into bottle necks of varying length and in connection with bottles of varying shape and dimensions, and by the term shouldered bottle I intend to cover any form of container which is flared or enlarged below the neck or equivalent opening.
