ELECTRIC CLOTH-CUTTER.

Specification of Letters Patent.

Patented Aug. 14, 1906.

1'0 all whom it may concern:

Be it known that I, JAMES BLAINE REP- LOGLE, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of .Illinois, have invented a new and Im 'roved Electric Cloth-Cutter, of which the fol owing is a full, clear, and exact description.

My invention relates to cloth-cuttingmachines, my more particular object being to produce 'a power-driven cutter operated, preferably, by electricity and combining certain advantages hereinafter described.

Figure 1 is a side elevation showin my cutter ready for use, certain parts being broken away for the sake of clearness; Fig. 2 is a front elevation of the same. Fig. 3 is a plan view of the cutter ready for use. Fi 4 is an enlarged elevation of the upper en of the connecting-rod 17, the pin 19 being shown in section. Fig. 5 is an enlarged sectional view through the upper end of the connecting-rod 17. line 6 6 of Fig. 1 looking in the direction of the arrow and showing one of the baffleplates, together with the knife and its mountings. Fig. 7 is a' side elevation of the knife removed from the cutter. Fig. 8 is a section upon theline 8 8 of Fig. 1, showing the bowl for. supporting the motor and the rlb for supporting the bowl; and Fig. 9 is a fragmentary section somewhat similar to Fig. 8, but showing the section as taken upon the line 9 9 of Fig. 1 looking in the direction'of the arrow. An electric motor 10 is provided with a shaft 11, revolubly mounted in bearings 12, and is provided with other bearings 13 14, which carry ,a revoluble shaft 15. Mounted upon the shaft 15 is a fly-wheel 16, which. supports a connecting-rod 17, the upper end 18 of the connecting-rod being journaled upon a crank-pin 19. The crank-pin 19 is provided with an oil-groove 20 (see Fig. 4) and is encircled by a bearing-sleeve 22, threaded into the head 18 and provided with spanner-holes 21, whereby it may be turned, and. thus-removed or adjusted to make a proper fit upon the crank-pin 19, so as to compensate for wear. The bearing-sleeve 22 is made of spring metal and is split at 23, being thus free to expand. The lower end of the connecting-rod 17 is provided with ahead 24, which engages a pin 25. carried by an adjust- Fig. 6 is a section upon the 'to the rib 32.

the cutting. edge of the knife.

able bracket 26, and secured rigidly to the bracket 26 by means of a thumb-screw 28 is a stem 27 of a knife 30, this knife being r0 vided with a serratede'dge 31 and being ollow-ground, its general shapeapproximat-iiig that of a razor-blade, as indicated in Fig. 7. A guiding-sleeve 27 a is mounted upon an an nu ar bracket 29 and supported thereby so as to guide the stem 27, which is free toslide vertically. A rib 22 .is rigidly connected with a handle 33, so that the latter may be used for manipulatin the device as a whole.

Extending downwar ly from the rib 32 and niounted upon 0 posite sides of the knife are guides 34. mmediately back of these guides and partially encircling the back of the knife is another guide 35. The guides 34 are connected together by means of baffleplates 36 and terminate at the bottom in a smooth plate 38, the guide also terminatr ing in a comparatively large plate 37, these plates fitting together neat as indicated at the bottom of-Figs. 1 and 2. A ide-sleeve 39 is integral with the annular bracket and is mounted rigidly upon the rib 32. Screws 40 connect the rib 32 with the guides 34, as indicated in Fig. 2. A brace 40 serves to increase the rigidity of the sleeve 39 relatively The motor 10 rests in a bowl 42, which in turn rests upon the rib 32, the latter being supported by the guide;stem 35.

My invention is used as follows: Power being applied to the electric motor 10, the revoluble shaft 15 is caused to turn. The fly wheel 16 thereupon rotates and acting through the connecting-rod 17 confers a reciprocatin vertical movement upon the stem 27 of the knife. The serrated edge 31 thus reciprocates vertically. The handle 33 is now grasped by the operator, and the front part of the plate 37 is passed under the cloth to be cut, the edge of this cloth passing easily between the lower baffle-plate 36 and. the upper surface of the plate 38. The entire device may be mhved somewhat after the manner of a pair of shears, so as to out the cloth 11 any desired shape. Similarly the device may be held, still and the cloth fed against The cloth is prevented fro 1 following the movement of the knife beca se of the fact that the cloth is unable to pass the baffle-plates 36 and is held against these baffle lates while the serrated edge of the knife ma res its successive strokes.

plates As indicated in Fig. 6, the guides, considered together, have a Wedge-like conformity, and thus serve as a spreader for the'cloth after the same passes the cutting edge of the I 5 knife and-isv divided. The feed of the cloth is therefore rendered comparatively easy.

When the device is used for cutting comparatively thin layers of cloth-as for in- .stancepsingle pieces used for an individual calledinto' use. When, however, a large number of layers of cloth are to be cut simultaneously, the machine is fed directly against the edge of the stack, the several baflleplates 36 finding their way between the layers of cloth, each consecutive pair of baffle-plates serving to prevent undue movement of such layers of cloth lying therebetween. The cloth is thus efl'ectivelyprevented from being-dragged out of position by movement of the knife, and consequently large quantities of the eloth can be cut according tothe same pattern.

It should be noted that the fly-wheel 16 absorbs energy at any moment when the knife happens not to be actually cutti n the cloth, and the power thus stored is uti ized when the edge of the knife makes contact with the surface to: be cut. The guides 34 35 together form a sort of. hollow bar having a triple functionsthat is, it serves as a sheath for the knife, a support-for the baffleplates, and aspreadenfor thecloth.
