corporation of- New 'Jersey Application February 7,519. serial No. 317.616

Claims. (Cpl. ISI-108) This invention relates' to tobacco feeding mechanism, and more particularly to improvements in devices for feeding short filler tobacco' of a relatively small size. l

According to my invention short filler tobacco is confined in a hopper provided with side' and rear walls and a substantially horizontal bottom, and means are furnished to cooperate with the hopper in confining a supply of short 'ller tobacco. In feeding some types of short filler tobacco, there have been used .with this type of hopper movable rakes which are placed at the hopper outlet and serve bothto confine and. control the movement of the tobacco from the supply contained inthe hopper by virtue of the movement of the rakes relative -to themselves andthe mass.

of tobacco conned in the hopper.

However when small scrap is used the rakes in themselves generally are not suicient to hold the tobacco in the hopper because the tobacco will ow through them and flow uncontrolled from part of this specification and wherein. the several reference characters designate the sameor like the hopper along the delivery portion which forms a part thereof, thereby upsetting the proper operation of the cigar machine with which the hopper is used.

It is, therefore, an object of my invention to provide mechanism for feeding small short filler tobacco wherein means are furnished to prevent an uncontrolled iiow of the tobacco from the container in which the supply is stored.

It is a further object of my invention to provide a hopper having side and rear walls extending upward from a tobacco supporting bottom in which confining means assist in holding the tobacco in the hopper and controlling itsiiow therefrom during feeding operations.

It is an additional object of my invention to provide an adjustably mounted control memberf for storing a quantity'of small scrap tobacco in" a hopper so that controlled quantities of tobacco canfbe fed from. the hopper.

My invention also consists in the provision of a hopper provided with a. substantially horizontal tobacco supporting and feeding surface and a member which cooperates with this surface for confining tobacco therein, and movable devices which coact with said member in controlling the feed of tobacco from the hopper and along the feeding surface.

With these and other objects not specifically mentioned in view, the invention consists in certain combinations and constructions which will be hereinafter fully described, and then set forth in the claims hereunto appended.

In the accompanying drawings which form a in my above referred to applicationin which an'electric vibrator I5 is adjustably mounted on elements: 1 Y

Figure 1 is a sectional side elevation showing the preferred form of my invention for feeding small short filler tobacco; l y

Figure 2 is a partial sectional end elevation taken on line 2-2 of Figure 1; y

Figure 3 is a sectional side elevation showing a modified form of a tobacco confining member;

Figure 4 is a partial view of a modified form' of confining plate;

Figure 5 is a side view showing mechanism'for intermittently vibrating the .hoper and oscillating the rakes;

Figure 6 is a section taken on line 8 6 of Figure5;and

Figure 7, is a suitable wiring diagram for use in intermittently vibrating the hopper and oscillating the rakes.

Referring to Figures 1 and 2 which show the preferred form of my invention. Ill designatesa hopper employed for feeding short lier tobacco which may take substantially the form as that disclosed in my co-pending application,` Serial No. 193,244. led Marchi, 1938, and wherein the i f hopper isprovided with side walls IIIa, a rear. t

wall lub and a bottom tobacco supporting surface luc having an outlet chute Il onto which the tobacco is fed from the, supply duringthe v feeding operation of the hopper. Asshown in Figures l, 2 and 5, surfaces IIIc and II are joined.- by a step or shoulder formed integrally.there-ffA with.

Hopper III, in the form shown, is resiiiently supported by means of -ieaf springs I4 bolted to lugs Ilaprojecting from .the bottom of the hopper (as shown in Figure 1) and is intermittently i vvibrated by means of a suitable device, described hereinafter, such for instance as thatv described a base block `I6`suitab1y attached to' the framel F of themachine.vv Extending upwardly from the 1 frame of the machine are pedestals 2|, 22 supporting at their upper ends, a housing-20. Housing 20 provides a mount for rakes I2 which'are suspended from a bar I'l and rakes I3 vwhich p roject from a bar I8, which bars are pivoted at their centers on a 'stud I9 mounted in the housl ing 2li.A One end of bar Il is pivotally connected t`o an operating lever 2l, and an end of bar Il is connected in a similar manner to lever 23, bothoperating. levers being pivoted on a stud and provided at their free ends with cam followers 26 and 21, respectively, which engage the track of a drum cam 23 mounted on a rotating vertical shaft 23 supported in pedestal 22.

. As shown in Figure 1, the tobacco confining member 30 is adjustably mounted on the rear face of housing 23. 'I'he plate is mounted rearwardly of the step or shoulder joining surfaces Inc and II, land is arranged between the side walls Illa and substantially at right angles thereto, and is also located at substantial right angles with the tobacco supporting surface Ic and is spaced therefrom a predetermined distance in order to allow a portion of the tobacco, which it confines in the hopper, between the side and rear walls, to flow therebeneath onto the discharge or outlet chute II for delivery to a cigar machine. In the illustrated embodiment, member 33 is shown as comprised of a solid plate but if desired, this member could be composed of several closely positioned plates which would effect the same desired result. Plate 33, in this case (as shown in Figure 1) is made of a single piece of metal and is provided with slots 3l through which pass screws 321 by means of which 1t is adjustably and detachably secured to housing' 23 in order that the space between the bottom of plate 30 and tobacco supporting surface IIIe can be adjusted readilyy to control the tobacco passing through the aperture formed by the plate and surface I 3c.

In Figure 4, the modified form mentioned hereinabove is shown, the tobacco conning member is made up of a. plurality of closely spaced plates 30a each provided with an elongated slot 3Ia through which project screws 32 by means of which the plates 30a are positioned at a proper heighth above the deck of the hopper IIIc.

According to Figure 3, which shows a modled form of my invention, a two-piece confining member is shown. This member consists of an upper part 33. which is detachably fixed to housing 20 by means of screws 32, while the lower portion 34 is provided with slots 33 through which project bolts 35 constructed and arranged to allow plate 34 to be moved relatively to and vertically with respect to plate 33 to control the height of plate 34 above surface IIic.

It will be seen, therefore, that my tobacco confining and flow control plate is adapted for selecf tive operation either with or without rakes I2, I3. That is, whenever the tobacco is very small, the plate can be used without the rakes and substantially the same eect would -be obtained in the uniform feed of'tobacco from the confining portion of the hopper between the bottom edge of the plate 33 and the discharge surface I I of the hopper. So also, if larger tobacco is to be fed, the plate 30 may be removed entirely in order that the rakes will act both to confine the tobacco in the hopper and control the feedtherefrom alongthe discharge portion II thereof.

Figures 5, 6 and 7 show suitable mechanism for intermittently vibrating the hopper and oscillating rakes I2, I3 for feeding tobacco from y motion of the rakes I2, I3.

Tobacco passing through the aperture formed f by vertical plate 33 and surface IIic and between rakes I2, I3 is fed over surface II to a scale pan P located beneath the discharge lip of the hopper (as shown in Figure 5). Pan P. as in my copending application referred to hereinabove, consists of a substantially vertical plate 13 mounted on arm 13 fixed on shaft 1I carried by bracket 13 secured to bracket 13. Pivotally mounted on studs 33 carried by the upper portion of plate 13 is a scale receptacle 3l which with plate 10 forms the pan P.

Whenever a predetermined quantity of tobacco has been fed into scale pan P, it swings downwardly on shaft I4 thereby causing a mercury switch 3|, connected in an electric circuit (see Figure '1) to break the circuit and de-energize vibrator I3. 'Ihis operation stops the vibrating motion of hopper III, and the oscillation of rakes I2, I3, thereby discontinuing the feed of tobacco to pan P.. The rake oscillation is interrupted upon-the de-energization of relay R by means of solenoid |33 which is tie-energized, thereby causing armature |02 connected by link I 0I to lever |33 to withdraw lug Ill from engagement with finger |03 of pawl 33 against the tension of spring |33. Pawl I3 will move into engagement with ratchet 33 causing ball clutch 61 on shaft 23 to disengage the latter from the variablel speed drive and thereby also stop the motion of rakes I2, I3. Lever |03 is pivotally mounted on a stud shaft 33 connected by bearing lug 33 (Figures 5 and 6). When the machine is running, line switch IIS is closed.

The invention above described may be varied i in construction within the scope of the claims.

the hopper. Hopper I3 is vibrated and rakes I2,

I3joscillated intermittently by mechanism similar to that disclosed in my co-pending applica-f tion hereinabove referred to. Referring to Figures 5, 6 and 7, vertical rake operating shaft 23 is drivenl intermittently by means of a conventional type ball clutch 31 (Figure 6) from a conventional variable speed drive designated' generally D secured in housing 36 (Figure 5). This for the particular device, selected to illustrate the invention, is but one of many possible concrete embodiments of the same.
