SPECIFICATION forming part of Letter S: Patent N 0. 672,096, dated April 16, 1901.

Application filed March 28, 1900.

T0 at whom it may concern: 7

Be it known that I, NAPOLEON DU BRUL, a citizen of the United States, residing at Oincinnati, county of Hamilton, and State of Ohio, have invented certain new and useful Improvements in Cigar-Bunching Machines, of which the following is a specification.

My present invention relates to a cigarbunch machine of thegeneral type described in United States Letters Patent of Fredrick C. Miller, granted September 8, 1896, No. 567,350, and of Albert Du Brul, granted November 14, 1899, No. 636,961, and which, generally speaking, comprises a tobacco-hopper, a matrix-slide by which the. filler is taken from the hopper in measured quantities and presented above the rolling-table, a plunger and cooperating follower by which the filler is discharged from the matrix into a pocket formed by therolling-apron, levers to operate the rolling-apron to form the bunch, a bunchcarrier into which the apron discharges, a mold-carrier supporting a mold over which the hunch is presented by the bunch-carrier and moving said mold intermittently to bring its several matrices successively into position to receive a bunch from the bunch-carrier, and a plunger for discharging the bunches from the bunch-carrier into the mold.

My present invention has for its objects to improve the construction of some of the parts of the machine above outlined, as well as to add thereto features that will improve not only the operation of the machine, but also the finished article produced thereby.

In the manufacture of cigars from out scrap more or less dust and small particles of tobacco are encountered in the material.

One feature of my improvement relates to means whereby each charge of tobacco as it is measured in the matrix of the sliding plate is subjected to a cleansing current .of air through it to remove the dust and finer particles therefrom. I also prefer to continue this air-suction during the interim in which the matrix advances to discharge its tobacco to clean the parts beneath the hopper of the dust and particles accumulating there, and thereby improve the ease of operation of the parts and save wearand tear which have heretofore resulted from these gritty accumulations.

.A further feature of my present invention relates to the construction of the bunch-carrier whereby the bunch, which has its form determined by the matrix and apron, may be deposited at different relative positions in the carrier, and consequently reach different relative positions in the mold. It freq uently happens that, owing to the condition of the filler material, the formed bunch will have too much bulk at one point and not enough at another, so that the finished article will be too tight or too loose at some point in its length. This feature of my present invention affords a simple means for overcoming this difficulty, and consists in providing the carrier with an adjustable operating connection whereby it will be held at different positions beneath the discharge end of the rolling-table and receive the bunch in different relative positions of the carrier, and consequently change the point at which the thick part of the bunch occurs in the mold. This construction is preferably such that the position which the carrier assumes over the mold for discharging remains constant notwithstanding any adjustment at the other end of the carriers throw.

My invention will be fully understood upon reference to the accompanying drawings, in

- which Figure l is a perspective view of my improved. machine. Fig. 2 is a front view of the same. Fig. 3 is a plan. Fig. 4 is an elevation of the side opposite to that seen in Fig. 1. Fig. 5 is a vertical longitudinal section through the filler-feeding mechanism. Fig. 6 is a detail view of the matrix-charging Fig. 7 is a front view of the bunchcarrier in its opposite position to that shown in Figs. 1, 2, 3, and 4:. Fig. .8 is a perspective view of the segregated parts of the bunchcarrier.

1 represents the hopper, formed with a bottom discharge-opening 2 and containing an agitator 3, oscillated by central shaft 4 to feed the filler material toward the opening 2.

5 is the matrix-slide, reciprocated in the base beneath the hopper through links 6 connecting the slide with the lever 6, fulcrumed at 7 and engaging cam 8, said slide having a matrix 9, which when the slide is moved by said lever and cam is moved from a position beneath the opening 2, where it is charged by a plunger 10, controlled through a link 11 and bell-crank lever 12 from a crankarm 13 on the shaft 4, to a projected position at the rear of the table 15, where the charge of filler measured and shaped by said matrix is deposited into the pocket 16 of apron 17 by the plunger 18 on vertically-reciprocating post 19 and cooperating follower 20, which is made to rise with the pocket to receive the filler by means of a suitable cam.

22 is a lever that holds the rear end of the rolling-apron.

61 represents the lever that carries the bunch-roller that rolls the bunch through the medium of the apron and discharges it into the carrier 23, by which it is conveyed above the m old, there to be deposited into the moldmatrix by a plunger 24 011 the post 19. Post 19 is moved vertically by bell-crank lever 25, fulcrumed at 26 and having its pin 27 engaging in cam 28.

20 is the mold-table, moved (see Fig. 4) in guide 30, step by step through the ratchet 31 and elongated spring-dog 32, which is moved by a short lever 33. The spring-dog 32 may be held out of engagement with its ratchet 31 by horn 34, carried by said spring-dog and projecting forward beneath the upper portion of a treadle-stop 35. (See Figs. 1 and 4.)

All of the operating-cams mentioned, as well as some others to be referred to, are mounted upon a main shaft 36, which receives driving power from any suitable source through clutch 37, whose controlling-lever 38 is moved in opposite directions-through pedals 39 40.

As thus far described the machine is substantially similar to that described in United States Letters Patent already recited, and a more detailed description of the parts above referred to is unnecessary to an understanding of my present invention.

Air-suction means-As shown more clearly in Fig. 5, the base is hollowed out to provide a suction-chamber 41, the top surface of the base upon which the matrix-slide works being formed by a thin plate 42. The plate 42, or the upper surface of the base, should it be cast with such a surface above the chamber, is perforated, as shown at 43, Figs. 3 and 5, beneath the hopper-opening 2 and the matrix when the latter is at or near its inner limit, and through these perforations a current of air is drawn so long as the matrix is in such position, air being prevented from entering the perforations from beneath the sides of the matrix by the contact of the latter with the plate. In order to induce an air-current beneath the other parts during the advance of the matrix-slide, the plate 42 has an opening 44 in rear of the perforations 43, and the rear portion of the matrix-slide is hollowed out at 45 to a point which comes just behind the rear wall of the suction-chamber when the matrix-slide is drawn in, but which point passes well forward of and overlaps the suc- (ion-chamber when the matrix-slide is forward, so that at such time there is a suction beneath and around the matrix-slide, the air entering at 46 at the rear end of the slide. (See Fig. 5.)

From the foregoing description it will be seen that the matrix-slide operates as a valve to determine the direction of the air-current; also, that the perforations 43 in the plate 42 or upper surface of the base permit the escape of fine particles and dust from the charge in the matrix, but do not interfere with the filler material therein or with the operation of the matrix-slide.

Air-suction may be induced in the chamber41 in any suitable manneras, for instance, by providing the base with a passage 48, that connects the chamber 41 with the outlet 49, leading to any suitable source of air-suction.

The bunch-carrier 23 is mounted on asliding track 50, extending beneath the discharge end of the table, and is reciproeated by means of a lever 51, fulcrumed at 52 and having a stud 53 engaging in the groove of cam 54, which cam is on the extreme front end of the main shaft 36. Lever 51 works across the front of said cam, and its fulcrum 52 is in a bracket 52, projecting up in front of the cam. Lever 51 is connectedto the carrier 23 by a pitman 55, the pin 56 of which projects from a boss 57, which is secured by nut 58 in a slot 59 in the end of the lever 51. By comparing the relative positions of the lever and the pitman at opposite ends of their throw, Figs. 2 and 7, it will be seen that when the carrier is beneath the discharge end of the table, or in position to receive the bunch, the lever and pitman are approximately in line and any adjustment of their connecting-pin will change the length of the connection with the carrier, and consequently the throw of the carrierin its return direction. By this means the position of the carrier beneath the discharge-point, and consequently ofthe bunch in the carrier, may be regulated at will; but when the carrier is over the mold the lever and pitman are substantially at right angles, or at least the pitman runs approximately transversely of the lever, in which position adjustment of the pitman effects no change, so that the outward throw of the carrier remains unchanged and the carrier always stops at the same position relatively to the mold and disch arging-plunger 24, whatever adjustment may be made in the pitman. In order that these relations of the parts may be strictly accurate, the slot 59 is concentric with the pivotal connection of pitman 35 to the carrier when the parts are at their outer limit.

It will be seen from the foregoing description that the bunch may be accurately located in the carrier at will and will be correspondingly placed in the mold, while the carrier always comes into proper discharging position above the mold to permit the discharge-plunger to descend through it.

As shown in Fig. 8, the bunch-carrier 23 is preferably made with a jaw 23*, movable on a longitudinal spindle 23", that Works in a socket 23 on the fixed portion of said carrier, in which it is held by a removable head 23 said jaw being rotated in a position to be held normally open by means of a spring 23. A stud 23 projects from the spindle 23 through an opening 23 and carries a roller 23 that runs upon a cam 5O along one edge of the guide 50. (See Figs. 1, 2, and 7.) Said cam 50 is provided with a depression 50 at one end, so that the roller 23 drops into said depression at the end of the stroke of the bunchcarrier and permits the opening of the movable jaw 23 to receive the bunch, while during the travel of the bunch-carrier the jaw is closed to hold the bunch securely in position and does not open again until returned to receive a new bunch.

Rear apron-holding Zeoer.As shown in Fig. 1, lever 22 is fulcrumed at 22 supports the rear end of apron 17, and is moved forward and backward by double cam 22. The cam 22 is so timed that the forward movement takes place to slacken the apron before the filler is deposited in the pocket and the rearward movement is madethereafter and before the bight has been formed by the rolling-lever to close the apron around the bunch. I thus provide positive means for slackening and tightening the apron.

Rolling-lever-Owin g to the desirability of having as long a rolling-table as practicable, I employ a long rolling-lever 61, having any suitable form of bunching roller and fulcru med at 62, near the bottom of the machine, and oscillated through the medium of a shorter lever 63, fulcrumed at 64, Fig. 3, having an intermediate pin 65, that engages in the cam 66, and connected by a link 67 with the rolling-lever. The shaft of the lever 61 extends through the machine, and lever 61 is duplicated on the opposite side of the machine. By the described arrangement of rolling-lever the table may be made much longer and flatter than heretofore and a better rolling effect produced. The binder is laid upon the apron previous to the rolling action, as is well understood in machines of this type.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:
