SPECIFCATILON forming part of Letters Patent No. 693,253, dated February 11, 1902.

`Application tiled .Tune 8, 1901.

To all whom, it may concern: y

Be it known that I, GEORGE H. FOLLOWS, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Oigar-Wrapper-Outting Machines, of which the following is a specification.

My invention relates to a machine having a cutting-platen upon whicha leaf of tobacco is suitably held, as by air-suction, in position to have a Wrapper cut therefrom by a coperating roller swinging from side to side above the' platen. Such machines have heretofore generally employed a cutting-die embedded in the table and a roller extending across the die and suitably mounted to swing from side to side and press the leaf into cutting contact with the edges of said die. It has also been proposed in United States Letters Patent of Albert Du Brul, No. 676,677, dated June 18, 1901, to provide a cutting-tool andV what has been termed a floating support7 for the tool, by Which-it is permitted to have freedom of horizontal movement in any direction and rendered capable of traversing the outline of a Wrapper, and a guide in Which the tool Works and by ywhich Vit is directedin a path conforming in outline to the Wrapper to be formed. This new system of floating and guiding the tool in a cigar-Wrapper-cutting machine gave rise to a novel plan of operation invented by the aforesaid Albert Du Brul, in which the die in the table is dispensed with and the cutting is accomplished by a rotary cutter in the operating end of the tool traversing an unobstructed platen upon which the leaf is held by air-suction, the shape of the Wrapper being secured by the guide directing the course of the cutter and the air-suction perforations being disposed so as to leave an uninterrupted cutting-path for the cutting-disk. For this type of machine United States Letters Patent No. 676,813 were granted June 18, 1901.

One feature ofrmy present invention is applicableV to both the aforesaid patent types of machines, and` consists in certain means whereby the tool is caused to engage the guide at a plurality of points.

'seria No. 63.761. (No model.)

bunch, said means being constructed to depress the platen to expose the edge of the die when the tool is returned to operative position. The platen-supportis preferablymoved' by a cani carried by the tool-mounting.

My invention .will be readily understood upon reference to the accompanying drawings, in which- Figures 1, 2, and 3 are respectively a side elevation of the machinefa plan of the tool and guide and their mounting, and a plan of the platen-support. Fig. 4 is a detail view of the cooperating tool, illustrated as having a roller pressing upon the edge of a die.

l represents the cutting-table; 2,l the diey embedded therein; 3, the perforated depressible platen Within the die, supported through guide-stems 4, working through openings 5 in suction-chamber 6. These parts are not new With me.

7 represents standards, in which is mounted a horizontal shaft 8, carrying a supporting-bracket 9, in the outer end of which is mounted a tool 10, thatcoperates with the cutting-die to effect the cutting operation. The type of tool here shown has a roller 11 mounted on a horizontal axis in its lower end, made to traverse the edge of the die to press the leaf thereon. It is important that the rolleror other formof operating end of the tool should remain at all times With its axis normal to the path in Which it travels-that is to say, with the axis of the roller (or of the cutting-disk in types using such) transverse to the edge of 'the die or line of travel-and it is desirable to have the operating end in the vertical line of the toois axis. This is accomplished by providing the guide 12 on the shaft S with a continuous groove conform- IOO ing in outline to the wrapper to be cut and having the tool engage therewith through the medium of a plurality of rollers or pins 13 on either side of or eccentrically disposed upon its vertical shank 10, entering the groove and alined therein and prevent the tool from turning or twisting relatively thereto.

14E represents a forked supporting-lever fulcrumed at 15 beneath the table, the forward ends of which being secu red between knifeedge Washers 1G and nuts 17 on the guidestems 5 of the depressible platen 3. The supporting-lever 14 is rocked upon its fulcrum in the direction to raise the platen 3 by a cam 18 on shaft 8 acting against the upper end of a vertical pin 19 when the guide and tool are raised from operative position after cutting a wrapper, and the depressible platen is to be sustained rigidly during the rolling action; but when the cutting-tool and guide are returned to operative position cam 18 releases pin 19 and the depressible platen is free to return to its depressed position.

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

1. A machine for cutting out wrappers from tobacco-leaf, comprising an air-suction table; a tool coperating with said table to cut out the wrapper, supported above the table, having freedom of horizontal movement relatively to the table, also having a vertical axis of rotation upon which it turns in its support, and impinging the tobaccoleaf at a point in the line of its said vertical a'xis; and a guide conforming to the outline of the wrapper to be cut, engaging the tool in the vertical line of its turning axis and positively directing its turning movement, as well as the direction of its travel relatively to the table, and keeping its transverse axis at all times normal to the edge of the wrapper being cut.

2. A machine of the type described for cutting wrappers from tobacco-leaf, comprising an air-suction table, a guide conforming to the Wrapper to be cut, a tool-support having freedom of horizontal movement over the table, and a tool coperating with the table to cut a leaf, having a rotary bearing in said support and a non-rotating bearing in the guide; the bearing in the guide, the bearing in the support, and the point of impingement of the tool with the tobacco-leaf all being substantially in the vertical axis of the tool.

3. A cigar-wrapper-cutting machine embodying a cutting-table having means for holding a tobacco-leaf thereon by air-suction; a tool-support mounted to have freedom of horizontal movement over said table; a guide supported above the table having a track conforming to the outline of the wrapper to be cut; a tool rotatable upon a vertical axis, on said tool-support, engaging the guide and caused to follow the same; a rotating part mounted in the lower end of the tool upon a horizontal axis in the vertical line of the axis upon which the tool rotates; and means carried by the said tool engaging the said track at a plurality of points in the line of travel; preventing the tool rotating upon its vertical axis relatively to the track and keeping the horizontal axis normal to the path of travel.

4. In a cgar-wrapper-cutting machine, the combination of a cutting-table having airsuction means for holding a tobacco -leaf thereto, a floating lcool cooperating with said table to cut out a wrapper from said leaf having a rotary operating end in the vertical line of its axis, and means for defining the path of said floating tool, consisting of the guide having a downwardly-presented groove conforming in outline to the wrapper to be cut, and a plurality of rollers or pins on the upper end of said tool entering the groove and alined therein and thereby preventing the tool from turning on its vertical axis relatively to the groove in which :it is confined, and holding the axis of its operating end normal to the path in which it travels.

5. n combination with a cigar- Wrapper cutting and rolling table having a cuttingdie, and a depressible platen within said die, a cooperating tool above the table, a movable toolsupport upon which the tool is moved into and out of working position in relation to the platen and a support for said depressible platen, having connection with the movable tool-support through which it is moved to raise the platen and permit its depression as the tool moves away from and into its operative positiomwhereby the platen aords a rigid support when rolling the wrapper upon the hunch.

6. In combination with a cigarwrapper cutting and rolling table, having a cuttingdie and a depressible platen therein, a tool coperating with the die to cut the Wrapper and movable into operative position for .cutting and out of such position to leave the table unobstructed for rolling, a supportinglever for said platen fulcrumed beneath the table, and holding the platen rigid when rolling the wrapper, and a cam on the tool-support, moving said supporting-lever in the direct-ion to raise the platen as the tool moves out of operative position.

7. In a cigar-wrapper-cutting machine the combination of a table, a die having a depressible platen, a tool that coperates with said die, a horizontal rock-shaft upon which the tool is mounted to swing vertically out of operative position,a supporting-lever for said platen fnlcrumed beneath the table, a vertical thrust-rod on the end of said lever, and a cam on the horizontal shaft engaging the thrust-rod as the tool rises, for the purpose set forth.
