29 Claims.

This invention relates to cigar machines, and more particularly to apparatus for feeding short filler tobacco and means for arranging the filler tobacco with the lengths of the several pieces extending in the same direction.

Short filler tobacco fed from the supply magazines on many cigar machines has no definite arrangement, so that the several pieces lie in any direction. If it be fed into the charge and bunch forming mechanism in this condition the cigars. formed therefrom may be unsatisfactory due to unevenness f the filler arrangement in the bunches, hard lumpy spots, the draft will be cut down so that the cigar may burn unevenly or be difilcult to smoke, and the short filler may be cut into smaller pieces when the bunch charges are formed.

According to the present invention it is proposed to eliminatesubstantially all of the above mentioned disadvantages by the provision of mechanism which will so feed the filler tobacco tothe bunch charge forming device, that the several. pieces'of filler constituting each quantity fed will be substantially aligned, or have their lengths extending in the same direction and maintain the size'of the filler tobacco substantially the same as it was when fed'from the magazine.

It is an object of this invention to feed short filler tobacco in such a manner that cigars made therefrom will be more perfect than short filler cigars heretofore produced.

It is an additional object to provide tobacco feeding mechanism including means for substantially aligning the short filler so that the pieces thereof will'have their lengths extending in a single direction.

It is a further object to arrange short filler tobacco so that the pieces thereof tend to lie in the same general direction for formation into bunch'lengths prior tothe introduction of the aligned tobacco into the bunch forming chamber.

It is also an object to provide mechanism for forming a substantially V-shaped short filler receiving and arranging pocket wherein as the tobacco enters the pocket it contacts the upper portions thereof. and the pieces thereof range themselves in the pocket with their lengths extending in one general direction.

It is an added. object to so feed short filler tobacco to bunch forming'mechanism that its pieces substantially all extend in one general direction, and the likelihood of further reducing the :sizeof the filler is practically eliminated.

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

In the accompanying drawings, which form a part of this specification, and in which like characters of reference indicate the same or like parts:

Fig. l is a side View of a portion of a short fillerbunch machine showing the aligning means;

Fig. 2 is an end view of the same taken on line 2-2 of Fig. 1;

Fig. 3 is a view of the lower portion of the tobacco arranging pocket, as shown in Fig. 1, with the trap door til removed; and

Fig. 4 is a cross-sectionalview of the pocket taken on line 4-4 of Fig. 1 showing how the particles of tobacco in the receiving pocket tend to be arranged in substantial parallelism with the pieces extending in the'same general direction.

Referring to the drawings, the hopper 5, which is mounted on the side frames 6 of the machine, carries straight plates 1 and a curved plate 8 which-together with a swingable gate '91 and a horizontal gate H31 controls the fiow of tobacco from the hopper as disclosed in my copending application Serial No. 24,992 filed June 5, 1935, now Patent No. 2,130,765.

When the pocket formed by membersB and 9. has been loaded and the hopper gate closed, the gate 9 swings to its lowermost or dischargingposition, thereby permitting the tobacco in the pocket to discharge into chute II. In the illustrated embodiment chute II is formed in two parts; an upper part II, and a lower portion [2 adjustably carried by chute part I'l. Tobacco discharged from the pocket above mentioned, falls into chute H, and is directed thereby into portion I2 which-in turn discharges into chamber l3; As described in the above referred to patent gate 9-swings back to'pocket'closing position and a new charge of tobacco is fed from the hopper into the measuring pocket.

Referring to the drawings it will be seen that the wide upper portion of part l2 of the tobacco transfer or chute converges into a width equal approximately to the length of a cigar bunch. The wallsof this part cooperate with plate or trap door 30- to form a'relatively narrow V-shaped charge receiving and aligning pocket wherein pieces of tobacco receivedtherein tendto range-themselves to extend in the same general-direction. In Fig. 1, it will be observed'that the bottom plate of the chute is in the chamber.

somewhat bowed or curved from the general plane of the chute. This design allows a maximum of tobacco to be held in a relatively small and narrow space, so that in the anticipated use of this mechanism the height of the charge in the receiving and aligning pocket formed by the lower part I2 of chute If and plate 3 will be well within the limits of the pocket forming members. The bottom of the chute I2a and the trap door as are so spaced that the pocket for the major part of its length has substantially parallel walls. This arrangement of parts insures the substantial alignment or rearrangement of the pieces thereof so that they extend in the same general direction. The short filler pieces which enter the lower portion of the pocket forming members can only move in a given path, and if not arranged in the manner above described when fed into the pocket will contact the pocket walls and be swung or moved around into substantially aligned position with the lengths'of the several pieces of each charge fed extending in the same direction that is, with the lengths extending at right angles to the path of movement of plunger 33.

If extra large pieces of short filler are to be fed or if very large bunches are to be formed, it may be necessary to make the receiving and aligning pocket larger. This may be done in several ways. of the pocket is shown in Fig. 1, in which an extension of lever 25 is provided with an additional hole 26a. By locating the fastening pivot of link 21 in this hole, door 39 is held farther away from the chute walls and the pocket formed thereby is made larger. When the size of the pocket is controlled in this manner, side plates 55 assist in holding the charge in the pocket.

A shaft I4 supported in frame 6, carries a loosely mounted lever I5 equipped at its upper end with a cam follower I6 engaging in a slot of an actuator block I6 which is attached to lugs I9 and 28 provided on the side wall 2| of chute H. a stud 23 supporting one end of a tension spring .24 which at its other end is suitably attached to the bed of the machine. The pulling action of the spring causes arm 22 to descend, thus swinging the lever I5, whereby the chute I'I, by means of the action of cam follower IS in the slot I7 of block I8, turns on its fulcrum 25 and moves to dotted position I2. As the chute moves to the dotted position I2 trap door which is spaced near and follows the side walls of the chute and forms therewith the filler tobacco receiving and aligning pocket, assists in spreading the tobacco in the compression chamber. Since the charges in the pocket are not dropped as a whole into the compression chamber but are spread therein under positive mechanical control, there is very little possibility that the pieces of the filler which have been arranged to extend in one general direction will twist or get out of that arrangement as they are laid The means which move door 30 in connection with chute II include an arm 26 or" lever 15, connected by link 21 to a lever 28 to turn the latter about its pivot 29 thereby swinging the door to open where it forms with chute II the tobacco receiving and arranging pocket or to closed position where it closes opening 3IU in the top of the compression chamber I3. An adjusting screw 3I, carried by the upper arm of lever 28, provides means for stopping One means of controlling the size A central arm 22 of the lever carries I the closing of the door 30 at a desired point, and also arrests the pulling action of spring 24 when screw 3I engages a stop pin 32 mounted on the exterior of the compression chamber.

After the chute has moved to position I2, and trap door 30 has closed the chamber I3, plunger 33 suitably operated by means described in my previously referred to patent, advances the tobacco into the cutting chamber 34, which by suitable mechanism also shown and described in said patent turns 90 and descends to position 34. In approaching this position the chamber encounters and forms a loop in rolling apron in which the charge carried in the chamber is ejected and rolled into a bunch. The charge is expelled from the chamber 34 by means of a plunger 3'! in a manner shown in Patent No. 2,021,652 granted to me on Nov. 19, 1935 The chamber now rises to starting position whereupon the bunch rolling mechanism may come into operation, and roll the charge.

A cam actuated rod 39 connected to a lever 46 also mounted on shaft I4 is equipped with a stud 4I engaging an adjusting screw 42 of arm 26. When lever 40 is turned the Stud 41 pushes against screw 42 and returns the chute from position I2 to its original charge receiving position, the chute retaining this latter position until lever 40 retreats, permitting spring 24 to again move the chute.

Means are provided for adjusting the charge and bunch forming devices to form cigars of different lengths. Side plates 53, 54 and 55 are adjustably supported on the machine table as shown in my Patent No. 2,021,652, previously mentioned. These plates are fixed in their desired adjusted position and then the two parts of chute portion I2 are adjusted to agree with the settings of the plates above described. The lower part of chute I I is provided with lugs 43 and 44 which cooperate with lugs 45 and 46 of chute portion I2. Lugs 43 and 44 are slotted and have passed there through adjusting screws which engage in lugs 45 and 46 to permit the adjustment of the parts of portion I2 to and from each other. Screws 430 and 460 extended through lugs 43, 44, 45 and 46 secure the two parts of the pocket in adjusted position. The lower portion I2 of the pocket is made up of two relatively movable sections having side walls 41 and 48 and bottom plates 5I and 52 provided with extensions 49 and 50 respectively, the plate 5| being on top and overlapping plate 52. As will be observed from Fig. 1, the side walls 41 and 48 gradually taper 01f from the top of the chute adjacent lugs 45 and 46 until at the mouth of the pocket adjacent the compression chamber opening 3I0 the side walls have merged with the bottom plates 49 and 50. It can be seen, therefore, that by loosening screws 430 and 460, plates 5I and 52 can be moved in or out and side walls 41 and 48 can be so set that cigar bunches of desired lengths can be formed.

The various means referred to may be varied in construction within the scope of the claims, since the particular device selected to illustrate the invention is but one of many possible concrete forms of the same. The invention is not therefore to be restricted to the precise details of the structure shown and described.
