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 CigarlVrapper-Cutting Machines, of which the following is a specification. Y

One object of my invention is to provide a machine by which the wrappers of cigars may be cutl out, and which shall have but relatively few parts and these of a simple, substantial construction.

I further desire to provide a machine of the class noted and of the general type in which a stationary die is employed in connection with a solid or one piece movable table and a roller, the die being of relatively inexpensive construction, both from the standpoint of first cost, as well as from that of maintenance.

These objects and other advantageous ends I secure as hereinafter set forth, reference being had to the accompanying drawings, in which Figure 1, is a side elevation of the upper portion of a wrapper cutting machine constructed according to my invention; Fig. 2, is a plan of the machine shown in. Fig. l; Fig. 3, is a plan of that portion of the machine for the support of the die; the table plate being removed; Fig. 4, is a vertical section taken on the line 1 -4, Fig. 2; Fig. 5, is a vertical section taken on the line -5, Fig. 1l; Fig. 6, is a partially sectional perspective view of the rolling table and part of the mechanism for operating the same; Fig. 7, is a perspective view of thecutting die and its associated structure, and Fig. 8, is a perspective view of treadle and its associated parts.

In the above drawings, A represents the body or main portion of the table forming part of my machine, which is supported upon legs a and has projecting near its rear edge a standard a. On this latter is mounted a vertical yspindle a2 supporting an oscillatory arm B; there being also carried on said standard a box or receptacle for iinished cigars.

The outer end of the arm B is provided with a handle b and has a longitudinally extended slot b for the reception of a bolt b2, holding the plate 723. A U-shaped yoke piece b4 carried by this plate 2f', has journaled in its ends a spindle or short shaft b5;

the bearings for the spindle being so arranged that its ends are respectively connected to downwardly extending, headed bolts b projecting beyond the ends of the yoke piece and provided with springs o7 between their heads and said ends. From Fig. 4,V it will be seen that the spindle b5 is free to move vertically relatively to the yoke piece b4, but is continually drawn down by means of the springs o7. Two independently rotatable conical frustums bs and b forming a roller are mounted on the spindle b5, being so placed that their small ends are in engagement or are adjacent to each other i being designed to coact with a die hereafter described.

The front portion of the table A, as shown in Figs. 3 and 4, is provided with an opening surrounded by an upwardly proj ecting edge or flange at and within this opening I mount an exhaust box C, having a substantially flat upper face c. Said box is connected by a flexible pipe c to a pipe c2 communicating with any suction device, such as a fan or pump, and its upper surface c has in it an elongated opening 03, which may be closed by a valve @t vertically movable within the exhaust box by means of a valve rod 05,' there being, if desired, a rubber gasket c, orl other similar device, extending around the inner edge of the opening c3 in order to prevent leakage of air through the saine when the valve is in its closed position. Removably mounted upon the upper surface c of the exhaust box is a cutting die I), which will be seen to consist of a hollow frame or body rl having the general external configuration which it is desired shall be given to the cigar' wrappers to be cut, and provided with an encircling length of steel ribbon cl forming the knife edge of the die.

As shown in Figs. 4E and 5, the body or frame d has its outer surface offset to the extent of the thickness of the knife (Z, so that when this is in place, its outer surface is substantially flush with the lower portion of the outer surface of said frame. I preferably make this knife of a length of spring material such as is commonly used in the manufacture of clock springs; it being understood that the edges of this spring ribbon, as manufactured, are sufficiently thin and sharp to serve tie purposes of my machine. In order to hold this spring knife in place IOO llO

CFI

I provide a number of removable clamping pieces d2, d3, d, etc., which are held by screws to the outer surface of the frame d; it being understood that their inner surfaces are preferably so shaped as to conform to the general curvature of the frame d, as well as to that of the spring knife. Conforming to the shape of the space inclosed by the said knife andv verticallyl movable therein is a suction plate d, having a number of perforations, as shown, `and held in place by means of bolts (ZG and springs (Z7 so that its upper surface is substantially flush with the upper edge of the knife CZ. Said bolts el pass through transl verse braces Z8 extending' from side to side l of the body or frame Z and are normally maintained in their uppermost position by l means of the springs Z7 which are placed l between said braces and the under side of upon the die frame,

said suction plate. At each of the four corners of the opening in the front of the table body A there are provided in the flanged portions a* vertical openings or guideways in which are placed vertically movable rods e, upon the lupper ends of which is mounted a plate E forming a table l for rolling the wrappers around the material l forming the fillers of the cigars. Said plate is removably attached to the rods c by screws l e and has an opening shaped to very closely conform to or fit around the knife tl of the die. The lower end of each of the rods e is engaged by one arm of a lever f suitably pivoted on a screw or pin j" to a lug` f2 prol jeeting downwardly from the under side of the body A. Confined upon each rod e, be- I tween the under side of said body and the end of the lever arm f is a spring f3, continually tending to draw down the rod and with it the table ll; itbeing understood that the four levers j are normally held by mechanism hereafter described, in such position l as to compress the springs f3 and maintain l the rolling` table E with its top surface flush with or above, the upper edge of' the knife (V, and, therefore, some distance above the upper edges of the flange a4. The second arms of the two levers f at each end of the exhaust box C, are extended so as to be engaged by the head g by a vertically movable rod g, and it. will be seen from Fig. 5 that these two rods g are rigidly attached to and extend upwardly from the ends of a horizontal bar g2. This same bar carries l at its middle point the valve rod ci and with l it the valve et of the exhaust box; this rod l extending upwardly through the bottom of l said box and having on it a collar 0S, which, when the rod is in its lower position, rests upon the bar g2 From Fig. 5, it will also be seen that the exhaust box C is mounted upon a pair of plates c held to the under side of the body A of the table by means of screws l a7 set therein, each plate resting upon a nut l i addition an adjusting screw a8 whose position upon its screw may bevaried, as desired. .Each plate has in a9 on each side of its supporting screw al and resting upon the surface of the under side of the body so as to permit either of the plates c and the exhaust box being held perfectlylevel or being given any desired inclination relatively to the body of the table A, in order to cause it to properly support the die D.

Fastened to the underside of the exhaust box C and projecting downwardly therefrom is a yoke piece H to which a lever it is held. by a pivot it, one of whose arms is forked to engage the collar es on the valve rod c5, while its other arm is pivoted to a second lever-7L so as to serve as a fulcrum therefor. Said lever /t has a roller /L2 mounted at the end of one of its arms and the transverse portion its of the yoke H has a cam surface with which said roller is capable of engaging soas to cause the lever /tto turn upon its pivot. lThe second or long arm of the lever la has connected to it one end of a rod or bar 7L* att-ached to an operating treadle 71,5 mounted upon a transverse shaft It on the lower portion of the frame of the machine, as indicated at A; each side of said lower frame being made with a one end of the shaft 7L is removably carried. Each of these pockets, as shown in l? S, serves as a bearing for one end of the shaft and by reason of its construction e'ectually prevents longitudinal movement of said shaft, while being constructed so as to permit of its removal, as will be understood from said figure.

Under operating conditions, the pipe c2 is connected to an exhaust pump or fan, and the treadle 71,, having its forward end in the position indicated in dotted lines in F ig. S, acts with the springs f3 to maint-ain the rolling table E lowered and the valve c* closed. That is to saj, the said springs are sufficiently strong to hold the table E down against `the flange c* and thereforerso hold the levers f that they keep the rod g in its elevated position. As a consequence, the cross bar g2 is also held in its upper position and since the treadle holds down the long arm of the lever 72.-, the valve c4 occupies its closed position. If now, the treadle be turned on its shaft 7L so as to push upwardly the rod itt, it will be seen that the lever 72. not only turns on its pivot,.but also causes the lever It to move on its pivot in such a direction as to force downwardly the rod The first result of this action is that the valve c" is opened to a slight extent so that a leaf of tobacco will be drawn down upon the perforated plate lf and held in position over the die D. By means of the arm B the roller B is now moved over the table, which is still depressed below the upper edge of the die knife d and a wrapper is eut out of pocket /L7 in which ioo the leaf. Further movement of the treadle now causes the roller h2 to move farther upon the cam of the yoke H and not only still further opens the valve c4, but compresses the springs f4 so as to bring up the rolling table E flush with or above the upper edge of the die knife cl. The waste portions of the tobacco leaf may now be removed and the wrapper rolled around the filling material in the well known manner; said wrapper being still held to the suction plate (Z5 by reason of the faet that the valve c* is open.

After the completion of the cigar the front end of the treadle is again depressed, thereby permitting the springs fg to lower the rolling table E and close the valve c4.

lt will be seen that by the use of a die knife made of a length of spring ribbon of the form described, I am enabled to employ a rolling table E made in one piece and verticall y movable with reference to the stationary die. Moreover, owing to the use of the spring knife, it is possible to make the rolling table E fit around said knife very closely without interfering with the action of the machine, while by using a stationary die l do away with the necessity for stufling boxes or sliding joints between the exhaust box and the exhaust fan or the pump.
