speeiaeation of Letters Patent.

Original application filed June l5, 1904, Serial No. 64,738. Divided and tlsapplication tiled September 25,1905. Serial No. 280,065-

To all whom it may concem:

Be it known that I, LESTER A. SICHAEF'FER, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented cer'- tain new and useful Improvements in Cutting-Rollers for Cigar-Making Machines; and I do declare that the following is a full, clear, and exact description of the invention7 which will enable others skilled in the art to which it appertains to make and usethe same.

My invention relates to machines for making cigars, and is a division of my application filed .I une l5, 1904, Serial No. 64,738.

In the accompanying drawings Figure 1 is a sectional elevation of the machine on a line corresponding substantially to B, B, Fig. 4. Fig. 2 is a sectional eleva-` tion showing the cutter roller and arm in normal or waiting position. Fig.A 3 is a plan View of the wrapper cutter arm and die-plate with the said arm`at the second arc of the said plate. Fig. 4 is a plan view of the cutter arm and die-plate, showing the roller actuating mechanism on said arm as about to be released for the action of the spring and with the roller in position to I turn on the arc beneath to normal position. Fig. 5 is an enlarged diagrammatic view of the die-plate, Showing the cutting roller atthe right in full lines in its normal position, and at the left in dotted lines at the beginning of its rotary movement, and again at the right in dotted lines in position correspondingsubstantially to Fig. 4.

The mechanism thus shown has to do principally with the roll for cutting the wrapper andmeans for carrying and operating the roll. Specifically said means or mechanism includes a roll supported on a vertical axis and adapted to be rotated on said axis to run around upon the edge of the die or wrapper cutter and sever the wrapper from the leaf as it goes. In this operation the roller runs to the left along the front or outer side or edge of the die, and back along the inner side cutting as it goes, and it is turned on its axis at the end of the die sufficiently to travel forward with the same front along the inner portion of the die as it maintained along the outer portion thereof.

The turning position of the roller is clearly disclosed in Fig. 3, and this turning is mechanicallyeffected when the swinging arm carrying the roller has reached the end of its outward sweep. As thus shown H represents the roller carrying arm, which is pivoted on the main frame or table of the machine in bracket H and has the cutting roller h mounted in the outer free end thereof. The said roller is journaled in bracket h on spindle. h2 supported in a vertical socket h3 in the arm I'I. A coiled or spiral spring h4 about the upper and reduced portion of spindle h2 in socket h3 is adapted to exert a constant downward pressure on the roller while at work, and serves to give the roller a firm but yielding l pressure. A crank or arm h5 is fixed on the upper end of 'spindle h2 above arm H with which connections are made for rotating the roller axially so as to follow the die or cutting edge c around from start to finish. y At this point I may explain that I find very material advantage following around the edge of the die with the cutter roller and cutting at only a single point in the travel rather than cutting broadly across the die at one sweep of the roller and going back idle, for the reason, rst, that by cutting with the whole roller at a time there is great danger of defective cutting at some point, here or there, and which leaves the wrapper unsevered from the leaf at such point. This is especially liable to occur at the ends of the die where the edges dull most easily, and sometimes it occurs more or less along the sides as well. But by running the roller around the circuit of the die I cut at only one point as I go and both avoid the objection of dulling some one or other 'prevented from proceeding until the wrapper is otherwise relieved. Furthermore, I get essentially a shearing cut all the way around by reason of the irregular curved outlines of the die and the different arc movement of the roller in respect to the die, so that I never fail to sever the wrapper all around and in no less time than the other way. Now, in doing this work, roller h adapts itself to the edge of the die and` switches around at both arcs, x and y, and cuts here also as it goes. Normally, said roller is entirely clear of the dieplate, Fig. 2, andthe space above said plate is otherwise unobstructed to allow said plate to be raised.

, But when lever H is carried to the left the roller first strikes the arc x, Fig. 5, and travels over the near edge of the die to the other arc y. Once there its spindle is axially and automatically reversed half way, which causes the roller to travel back on the inner side of the die, as it has done in dotted lines at the right in Fig. 5. From this latter point it turns to the intersection of its original position on arc x and at the same time is automatically reversed to starting position, full lines. The mechanism for effecting these operations is mostly carried by lever H, and consists of a reversing or switching crank h6, rod k7 connecting crank h6 with crank h5. Spring hs is likewise connected to crank h5, and at its other end to cam hm which is rigidly attached on Crank hG inward from its pivot h5 on lever H. Crank h6 has a cam g directly off its pivot to the rear adapted to be engaged by a fixed projection g on stationary arm H2, as reversal of roller h is to be made and as shown as partially turned in Fig. 3. Once at this point a further push of lever H to the left throws crank h5 by means of projections g past its center and brings it under the pull of spring hs to complete the reversal. Then the Patented July 16, 1907'.`

parts instantly assume position as in Fig. 4, and the reversing action of spring h8 is temporarily suspended by spring pressed headed bolt g2 engaging at its upper point in a hole in cam h1", thus for the time connecting said parts rigidly, as in Fig. l.

Upon returning lever H to normal position an arm g3, with a beveled edge and operating as a cam enters over the langed head oi bolt g2 and depresses it suciently to disengage its top point from cam hw, thus liberating the parts again to the pull o springhg. As this disengagement occurs the roller h has reached the reversing point ot the arc oi the wrapper cutting die, and spring h8 instantaneously reverses roller h through its operating and associated parts ba ck to nor- Inal position.

Incident to the last reverse action of roller h by spring h8 there is such impetus given to the roller that it at once assumes its right working position, but spring h8 would carry it back out of this position more or less if not prevented. To this end I employ a spring pressed bolt g, Fig. l. Normally said bolt is up, and is only depressed when crank h5 rides over it, said crank being beveled on one side to do so. Bolt g4 is acting as a back stop in Fig. l and always when the parts are normal.

Roller h is in initial but opposite reversing positions in both Figs. 3 and 4, and a corresponding position to Fig. 4 is shown in dotted lines Fig. 5, and the reversal thereof and the other details of its operation will be understood from the description already given. Assuming now that lever II is normal, roller h rst assumes position as to the die as it is moved up to full lines, Fig. 5, and then travels around upon the edge of the die and reverses upon its arcs as already described and with the operating parts relatively as seen in Figs. 3 and 4, just before each reversal occurs.

It is to be observed that the circle of the die is the path the cutting roller describes in its complete movement or trip, and that said roller sweeps its outer end around at the points x and y at what are regarded as the ends of the die so as to keep the outer end out all the time. In no case does the roller overreach both edges of the die at the same time, and the peculiar shape of bracket h contributes to'this result. Thus,

it is noticed that said bracket is of a crank or L pattern or shape, having the spindle or shaft h2 connected with the end of its horizontal arm, and the shaft for roller h engaged through the end oi its vertical arm. This brings spindle h2 over one end of roller -h, and it maintains this relation to the roller as the roller travels its circuit over the edge of die c, as seen in dotted lines Fig. 5.

What I claim is 1. In a machine for making cigars, a pivoted arm adapted to swing horizontally back and forth within fixed limits, a cutting roller mounted thereon and means to cause said roller to travel on two different arcs of a circuit with the arm pivot at the center of its movement, in combination with a die plate having a continuous and irregular curved cutting edge disposed obliquely to the travel of said roller to provide a shearingcut.

2. In a machine for making cigars, a die with circular ends, in combination with a pivoted arm, a roller on said arm and means to reverse said roller at the ends of said die comprising a spindle and crank for said roller, a switching crank and lever connecting the same with said roller crank, a spring pressed bolt and springs for said parts, and stationary projections adapted to engage said switching crank and said bolt.

3. In a machine for making cigars, a horizontally mov able arm, a cutter roller and a bracket supporting the roller having a vertical shaft in said arm, and means connected with the top of said shaft to turn the same conrprising a pair of connected levers and a stationary part to actuate said levers.

4. In a machine for making cigars, an arm, a cutter roller thereon and a vertical shaft in said arm supporting,r said roller, in combination with a switching crank having a cam, connections from said crank to said shaft, and meansto engage said cam and rotate said shai't, whereby said roller is horizontally rotated.

5. In a machine for making cigars, a horizontally rotatable arm, a roller and a bracket carrying the roller having a crank spindle rotatable in said arm, in combinat-ion with mechanism to rotate said-spindle comprising a connecting lever and a reversible crank and a spring therefor, and stationary means adapted to engage said reversing crank during the movement of said arm.

In testimony whereof I sign this specification in the presence of two witnesses.
