Specification of Letters Patent.

Patented July 12, 1910.

To all whom it may concern:

Be it known that I, BENJAMIN A. WIL- LIAMS, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Cigar- VVrapper Cutting and Rolling Machines, of which the following is a specification.

The object of my invention is to simplify the construction and operation of a machine for cutting cigar wrappers, whereby one motion will only be necessary to cut the leaf.

My invention relates to other details described hereafter.

In the accompanying drawings :Figure 1, is a plan view of my improved cigar wrapper cutting machine; Fig. 2, is a front elevation; Fig. 3, is a side elevation; Fig. 4:, is a sectional view on the line 44, Fig. 1; Fig. 5, is a sectional plan view on the line 55, Fig. 4; Fig. 6, is a detail view of Fig. 4t; Fig. 7, is a sectional view of the roller; Fig. 8, is a sectional view on the line 88, Fig. 7 Fig. 9, is a detached view of the cam.

A is the table, supported by suitable legs A in the present instance, and at the front of this table is an elevation A on which is secured a platform a. This platform is of suflicient size to allow for the cutting of the leaf and the wrapping of the cigar. In the platform is an opening a shaped to conform to the wrapper to be out; these shapes may be modified according to different forms of cigars.

C is a cutter frame having extensions 0 at each end arranged to slide on vertical rods 6, e secured to the table A by screws 6 in the present instance. Extending from one rod to another is a cross bar E Vertically adjustable by means of nuts 6 adapted to the screw threaded portions of the rods 6. The cutter frame C has resting upon it a frame 0, conforming to the shape of the opening a, and a knife 0 is secured to this frame by clamps which are held in place by screws 0 shown clearly in Fig. 6. The blade is simply a flexible flat blade of metal, which can be bent to conform to the shape of the projection c and is preferably beveled to a sharp edge, the bevel being on the inside as indicated in the drawings. The blade, therefore, makes a neat fit against the platform a.

Within the opening a in the platform is a a perforated plate D and projecting from the plate are bolts 0?, (Z; these bolts pass through cross bars on the extension 0 of the cutter frame 0 and on these bolts are nuts which limit the upward movement of the plate. Springs d mounted between the plate and the cross bars tend to force the plate up so that it will be level with the platform when the knife is depressed, as in Fig. 4:. Adjustable stops (Z carried by a T-bar D extending through the frame C and secured to the cross bar E by a set screw as shown in Fig. 2, limit the downward movement of the plate D.

The cutter frame O is made hollow to form a suction box, to which is connected a suction pump so that when the leaf is placed on the platform above the perforated plate D it will be held down onto the plate by suction, and on the upward movement of the cutting knife when the roll passes over the plate the leaf will be out, that portion outside the knife being readily removed but the portion inside the knife being held until the suction pump is cut off.

F is an arm pivoted to a bracket F at the rear of the table A.

f is a shaft carrying the arm and this shaft is held between two center points 7, f adjustably secured to the bracket F.

On the outer end of the arm F is a handle f by which it is operated, and near the outer end of the arm is a slideway f in which is a slot 7, and mounted on the slideway is a frame F carrying a roller F.

F is an overhanging bracket secured to the arm F, back of the frame F and a bolt f passes through a slot in the frame, the slot in the arm and a hole in the bracket F confining thethree parts. Set screws 7 on the overhanging portion of the bracket F bear upon the end of the frame F and by these set screws the frame can be set so that its roller F will properly aline with the plate. The roller is made in two parts 9, g, as shown, so as to prevent the tearing of the leaf by the roller when it travels over the platform. Ipreferably mount the two parts of the roller F, as clearly shown in Figs. 7 and 8, on a shaft G adapted to bearings in the frame F and carried by the part 9 are antifriction rollers g which bear against the surface 9 of the section 9, so that one roller will freely travel independently of the other.

Carried by the shaft 7 is a cam I having a cam slot 6, clearly illustrated in Fig. 9. Pivoted at 2" on the underside of the table is a lever I having a pin or roller 2' which enters the cam slotiin the cam I. This lever I is connected to a lever I also under the table, by a rod I made in two part-s, the two parts being coupled by a union 2' so that the connecting rod can be readily adjusted. The lever I is connected by a two-part link I to a bar of the toggle lever K, one link 70 of which is pivoted to the plate E at 72 and the other link 70 being pivoted to the underside of the cutter frame at c. There are two of these toggle levers, one at each side of the center, as illustrated in Fig. 2, and a single bar 70 extends from one joint to the other. The connection between the bar 72 and the link I is in the form of a ball and socket joint 70 but another form of joint may be used without depart-ing from my invention. It will be seen that any movement of the cam I will cause the toggle lever to raise or lower the cutter frame C. The movement is very limited but it is sufficient for the purpose. The cam I is so mounted in respect to the arm F carrying the roll that the first movement of the roller across the platform will cause the cam to move the knife up in position so that when the roller is directly above the opening a in the platform the knife will be in position so that the roller will force the tobacco leaf down upon the knife, cutting it in the desired shape. As soon as the roller passes the opening in the platform the knife is depressed clear of the surface of the platform and the operator can roll the wrapper upon the filler.

M is a suction pipe leading to a suction pump or other suction device and this pipe as a series of nozzles m, one at each machine, where a series of machines are used. The nozzle is connected to a valve box N by a flexible pipe on. The valve box N is secured to the underside of the table A, as clearly shown in Fig. 3, and the outlet from this valve box is connected to an extension 0 of the hollow cutter frame O by a flexible connection m In the valve box is a valve n pivoted at n and connected to this valve 12 is a rod n extending to a foot lever at the base of the machine. A spring a extends from the valve box to the rod, as clearly illustrated in Fig. 3, tending to normally maintain the valve in the closed position shown by dotted lines, so that when it is wished to hold the leaf down by suction on the perforated plate the rod n is depressed by a foot lever, thereby opening the valve 02 with the result that the suction immediately draws the leaf down onto the plate.

The operation of the machine is as fol lows :The roller arm is moved to one side of the machine, in which position the knife is depressed. The wrapper is then placed over the perforated plate, the foot lever is depressed operating the suction valve so that the suction will tend to draw the leaf down upon the plate and hold it in this position. The roller is then moved over the platform and before the roller reaches the opening in the platform the cam has elevated the knife to the cutting position and the roller is moved across the platform in contact with the wrapper, pressing the wrapper against the edge of the knife and thus severing the wrapper on the lines of the knife. The movement of the arm is continued until it is clear of the platform and the knife has been depressed by the cam; then the parts of the leaf outside the knife can be readily removed while the suction still holds the par-t cut by the knife until the operator is ready to apply the wrapper to the formed filler, when the valve is released and the connection with the suction device is cut off. There is sufficient space between the opening in the platform and the operator for the proper rolling of the wrapper onto the filler, after which another wrapper is placed in position and the above operation repeated.

I claim:

1. The combination in a cigar wrapper cutting machine, of a platform having an opening; a knife arranged to be raised and lowered; an arm having a roller mounted to travel over the platform; with means consisting of a cam; a lever actuated therefrom and toggle mechanism positively connected to said lever and also to said knife; the parts being assembled to raise said knife to its cutting position when the roller is moved over the platform.
