To @ZZ whom it may concern:

Be it known that we, SIMON HARTMAN and TILLIAM H. VVIGMORE, citizens of the United States, and residents of the city and county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improve ments in Cigar-Rolling Tables and Leaf- VVrapper Cutters, of which the following is a specification. f

Our invention relates to improvements in rolling-tables and machines for cutting cigarwrappers; and the object of our invention is to furnish certain improvements in that class of combined rollin g-tables and cigar-wrappercutting machines that comprise a cuttingknife, a suction-die, used as a rolling-table, and means for causing the leaf to be forced against the knife in order that it may be cut to the proper shape. Y

Our invention consists of an endless knife having the form of the wrapper, of a perforated suction-plate formed of an elastic or yielding material, as rubber, placed inside said knife, of means for supporting said plate, of means for creating a suction or partial vacuum beneath said plate, of means, preferably a roller or rollers, for forcing the leaf to be cut against the plate and for compressing the latter sufficiently to lower it beneath the level of the cutting edge of the knife in order to bring the latter into operative connection with the leaf, and of an electricallyoperated exhaust-fan, with one of which each table is equipped, to create the necessary su ction beneath the suction-plate.

In the drawings, Figure l is a plan of a cigar-makers table furnished with our improved wrapper-cutting device; Fig. 2, an enlarged plan of part of table, knife, and suction-plate; Fig. 3, a section of Fig. 2 on line A B, showing exhaust-fan and the connection between the same and perforated die-plate; Fig. 4, a section of Fig. 3 on line O D; Fig. 5, a cross-section through a modified form of die-plate.

ct is a tabletop; l), an endless knife; c, a

, suction plate or die placed inside knife l) and furnished with perforations d, ande is a perforated plate, screen, or series of bars which supports the suction plate or die and which is secured to table ct by screws for otherwise. The perforations in the plate c register with those in the die-plate c.

g is a box or pipe, one end of which is connected with or closed by perforated plate e and the other end of which is connected with an exhaust-fan 7l'.

a', Fig. 1, is a roller carried on an arm j, pivoted at k to table a and furnished at its other end with an operating-handle t'. This roller is adapted to be moved back and forth over the knife and die-plate. m are screws fastening the die-plate c to the perforated plate e. The edges of the die-plate are slightly higher than the cutting edge of the knife, and' in order that these edges may not be forced over the edges of the knife by the roller 't in its passage over the die-plate the edges of the die-plate are chamfered off or rounded, as shownjn the drawings.

In operating the machine the leaf of tod bacco is placed over the die-plate and knife. The suction-fan h, exhausting air from box g, carries an inrush of air through perforations d in the die-plate, and as soon as the leaf touches this plate the suction closes it tightly against it. The rollert' is now passed over the leaf and plate, forcing the latter down and bringing the formerinto contact with the knife, which cuts out of it a piece corresponding in shape of the knife. After lthe passage of the roller the elastic plate rises, and the 'wrapper being still held against this plate by the suction the filler, which has been already .brought to the proper form, is placed on the Wrapper and being rolled over is transferred to the ller in the usual manner. During the operation of wrapping the cigar, the suction-plate being higher than the knife, there is no danger of the knife cutting either the wrapper or the operator. As the roller t travels over the suction-plate it not only presses this plate down, but also tends to push it in the direction of motion of the roller. To prevent displacement of the plate, we secure it to the perforated plate e by means of two or more screws m, as shown in Fig. 2.

In the drawings the top of the suction-plate is shown slightly concaved, and this is the construction that we prefer, because the roller IOO has only to compress the edges of the plate in order to bring the leaf into Contact with the knife; but it will be understood that the plate may be flat or of any other shape desired.

In Fig. 5 the modifications of our invention are shown. In this case the suction-plate proper is formed of perforated metal; but between it and the knife is a band of elastic material n, as rubber, which projects somewhat above the top of the knife and suction-plate. The bottom of the suction-plate is connected with an air-exhausting device, preferably an electrically-operated exhaust-fan, which can receive current from any light circuit. This adjustment permits the use of the machine at any place where an electric current may be had, and does not necessitate the employment of an engine to operate the suction-making device, as has heretofore been necessary.

XVe claiml. In a cigar-Wrapper-cutting machine, in combination, an endless knife, a perforated suction-plate constructed of an elastic material within said knife, means for exhausting air from beneath said suction plate, and means for compressing said plate and bringing a leaf of tobacco carried thereby into contact with said knife.

2. In a cigar-wrapper-cutting machine in combination, an endless knife, a perforated elastic suction-plate, the top of which is concaved, placed within said knife, means for exhausting,r from beneath said suction-plate, and means for compressing said plate in order suction-plate constructed of an elastic material, extending slightly above said knife, a perforated support for carrying said suctionplate, means for exhausting air from beneath said plate, and means for compressing said suction-plate in order to bring a leaf of tobacco carried thereby into contact with said knife.

5. In a cigar-Wrapper-cutting machine, in combination, an endless knife, a perforated suction-plate the sides of which are elastic, and which project slightly above the cutting edge of said knife, means for exhausting air from beneath said plate, and means for compressing the sides of said plate in order to bring a leaf of tobacco carried thereby into contact with said knife.
