CIGAR OR CIGARETTE WRAPPER .CUTTING IVIACHINE.

SPECIFICATIN forming part of Letters Patent No. 593,878, dated lNovember 16, 1897'. Application tiled April 8, 1897. Serial No. 631,284. (No model.)

To all whom t may concern.-

Be it-known that I, NAPOLEON DU BRUL, a' citizen of the United States, and a resident of Cincinnati, in the county of I-Iamilton and State of Ohio, have invented certain new and useful Improvements in Cigar or Cigarette T/Vrapper Cutting Machines, whereof the fol-V lowing is a full, clear, and exact specication.

My present invention relates to machines which employ a hollow cutting-die over which the tobacco-leaf is placedl and upon which it is held smoothlyT by means of atmospheric pressure induced by exhausting the air from beneath some or all of the leafs area outside of the cutting-die and a suitable pressure device whichV bears above the leaf upon the edge of the cutting-die, while one of said parts moves relatively to the other and'effects the cutting action.

My present invention consists in novel features of construction in such a machine whereby it is better adapted to perform the several functions of such amachine-as Well as to perform new functions not heretofore attainable with machines of this class as formerlycon` s'tructed and whereby the constructionv of the machine as a whole is improved, as hereinafter describedY and claimed. A

My invention will be fully understood upon reference to the accompanying drawings, in whichv Figure 1 is aside elevation of myimproved machine. Fig..1a is a detail vertical transverse section showing a view, on an enlarged scale, of a part of the head of the arm show n in Fig. 1. Fig. 1b is a side elevation showing `a detail view of a slightly rounding or taper;

ing roller wherein the curvature of the periphery is slightly exaggerated for the purpose of illustration. Fig. 2 is a front elevation. Fig. 34 is a rear elevation. Fig. 4 vis atop plan. Fig. 5 is av central vertical section from front to rear through the table, suctionchamber, cutting-die, and device for apply ing cutting pressure to said die.

1 represents the legs vor frame, which `may be of any suitable construction, but which l prefer to provide with4 front brackets 2 to support a trough 3 for scraps of leaf and with rear brackets 4 to support an air-trunk 5, which has to do with the suction apparatus to'be hereinafter described. The frame may ness ofthe cut.

also be provided with a horizontal lateral shelf 6 to hold material frornwhich the wrappers are to be cut, or for other convenient purpose, and an inclined lateral shelf '7, upon which to placea cigar-mold containing the fillers which. are to be wrapped. 8 represents the table, and 9 is a shelf supported by brackets l0; but these features may be varied at will without departing from my present invention.

11 represents the removable platen, which surmounts and covers a suction-chamber 12, mounted upon the table 8, and 13 isa removable hollow open cutting-die mounted on the table within the suction-chamber, so that the latter surrounds it and protruding slightly lthrough the platen, so that the leaf may be cut upon it. v

14 is an oscillating arm pivoted in any suitable manner upon the table-as, for instance, between set-screws 15A and 16 inthe -upper and lower ends of a standard 17, which is securedtothe table. Y

18 is a pressure device of improved novel construction to be presently described, and 19 is the customaryhandle, by which the arm 414 may be moved when it is desired to eect this by hand.

According to one of the features of my present inventionI make the cutting-die 13 hollow and open at the top--that is to say, without a supporting block or fillingthe object of this being to provide a well or pocket into which the wrappers may drop or bev forced as they are cut. I thus provide for cutting in rapid succession andcollecting a number of wrappers, which may afterward be successively withdrawn and utilized in the usual manner or removed in bulk to any place of use. In order to avoid creating a vacuum in the cutting-die,` I maintain it in communication with` the outer atmosphere by making one or more openings-such, for instance, as

an opening 21in the bottom of the well `of the cutting-die, which admits vnormal atmospheric pressure to said cutting-die atY all times and avoids the development'of vacuum in the latter, which might occur and cause the leaf to sag and interfere with the'smooth- The opening 21 or such other openings as may be employed are of suicient width to avoid stoppage of the air by the IOO wrappers as they accumulate within the eutting-die.

There are several other advantages in employing the kind of die described. For instance, it avoids the drying out of the tobacco wrapper by the air-suction, which is very desirable in the manufacture of certain classes of cigars.

A further advantage is that it permits the work to be classified-that is to say, it provides for employing cheap labor to cut out the wrappers, while the time of the skilled labor need only be employed in applying the wrappers.

A further feature of my present invention relates to means for holding the tobacco-leaf during the cutting operat-ion, for which purpose I provide perforations 22 in the removable platen 11 outside of the cutting-die, and thus obtain ample holding force to insure the smooth and accurate cutting of the wrapper.

As shown in Figs. 1, 2, and 5, apipe 23 connects the suction-chamber 12 with the airtrunk 5. Any other suitable connections for developing pressure in the chamber 12 may, however, be employed.

The pressure device 18 comprises two independently-mounted

parallel rollers

24 and 25, bearing upon the respective sides of the cutting edge of the cutting-die and made independently yielding in a vertical direction to cause them to press uniformly on every point of the cutting edges as they pass over the leaf, and thus insure perfect cutting. The rollers also overlap each other in such a manner as to fully cover those parts of the edges which extend more or less in a direction transverse to the travel of the rollers. Each roller may be made slightly rounding or tapering, as shown at 25 in Fig. 1", in order to avoid contact with the leaf except at the point of cutting. The manner of mounting the rollers will be understood upon reference to Fig. l, wherein 2G represents a box which receives the spindle 27 of a hanger 2S, and in said hanger is mounted the journal 29', upon which the roller is iixed by adj ustablecollars 30. (See Fig. 5.) The spindle 27 has a reduced portion 3l, surrounded bya spring 32, which is confined between the upper end of the bore in the box and the shoulder 33, formed on the spindle. Upon its upper end the spindle is threaded to receive jam-nuts 34, by which the roller-mounting may be adj usted to different heights. Aside from the advantages named as incident to these rollers it is obvious that they can be moved longitudinally upon their axes after they have become indented from wear and can be interchanged, so as to bring new surfaces into play, or when worn to a great extent a roller can be replaced at small cost. )Vhile I have shown this form of pressure device mounted upon a swinging arm, it is quite obvious that it could be mounted upon a reciprocating carrier, which slides from side to side, or the same eect could be produced and many of the advantages attained by having the pressure device ixed and making the cutting-die with its surrounding parts slide relatively beneath the rollers.

To operate the swinging arm 14 or any other form of carrier which may be employed tol carry the rollers, said carrier is provided with an arm 35, (see Fig. 5,) which is connected by links or equivalent connections 3G (see Fig. 3) with the upper ends of a pair of bellcrank levers 37 and 33,1`ulcrumcd, respectively, at 39 and 40 and having their horizontal arms connected by rods or equivalent connections 4l with

pedals

42 and 43. The carrier or arm 14 may thus be reciprocated from side to side by pressing the pedals alternately.

Vhile I have described the open die in which the wrappers are accumulated as they are cut, it is obvious that the remaining features of my present invention are by no means restricted to use in combination with a cutting-die of this character, but are applicable to machines in which any form of cutting-die is employed.

The platen 11 is secured by screws to the suction-chamber, so as to be removable, which is of great advantage, as it provides simple means whereby the changing of the cuttingdie and surrounding platen is readily accomplished.

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