To allwhom it may concern: 9 1 i Be it known thatI, HENRY OhPEAsm'of Worcestendn the county of Worcesterand State of Massachusetts, have invented certain Cutting Soles for Boots and Shoes and, other Similar Purposes; and I declarethe, following to be a description of my said invention, sufticiently full, clear, and exact to enable others 1Q skilled in the artto which it appertainsto make anduse'the same, reference beinghad tothe accompanying drawings, which form a part: of this specification. 1 a i i My presentiinvention relates to certain improvements in the construction of that class of machines which are employedifor cutting out the soles of boots and shoesporothersimh lar articles by the aid of cutting-I 'os, the ob jects of theinvention being to provide a more 20 serviceable, convenient, safe, andefticient machine than :those heretofore in use;lto make i the supporting-frameso thatit shall be strong and rigid againsttorsional strainsor twisting action when the die is used underone end, of z 5.. the striker or follower; toaftbrd a double guide for the follower, so that its plate will operate square and level withthebl'ock orcuttingbed; to provide mechanism for intermittingly op- 'eratin g the striker without thenecessity of an automatic stop-clutchupon theidriving-shaft; to provide meansfor; sustaining the striker against accidental depression l to impart greater stability and permanence to the mechanism by locating the heavy moving parts 3 5 near the base to avoid shocks and severe strains by thestopping and starting of the mechanism whenjmaking the stroke or driving the die, and to render the machine operative. without waste of power; also, toalford convenient facilities for actuating the blockadjusting mechanism constructed in the manner herein illustrated and described,- theipartic ular sub ject-matter claimed being hereinafter definitely specified. 1 4 In thedrawings, Figure 1 represents a top view of a sole-cuttinglmachine embracing my invention. Fig-.12 is a vertical longitudinal section at line as m. Fig. 3is a front view of the machine. Fig. 4: isa sectional plan view at line 3 y. Fig.5 is a transverse vertical secnew and useful Improvements in Machines for 4' mechanism. These objects Itattain by the t.

ti onvthrough. the strikerhead. Fig. 6 is a transverse section of the top frame and work- I foractuating the block-adjusting devices.

1 In referring to the drawings, A denotes the main-frame; B, the block or cutting-bed; O, the operating crank-shaft; D, the depressinglever ;;E,.the crank-connector or pitman; F, the follower or striker; G, the starting-treadle;

.quoin-block or chocking-piece; K, the headbalance or elevating-spring; L, theadj ustin g handle-forworking the block-elevating gears,

all of; which hparts areolocated in relation to eachother as indicated.

e The frame'A, I construct in the peculiar form shown,with two vertically-extendlin g ribs or webs, A, located at"son1e distance apart upon the body-flange a, and running parallel,

or nearlygso, from the lower front of the 1113- chine around the back and to the upperfront of the overhanging portion or head, said webs A beingconnected or braced to each other and to the body-flange a at occasional intervals by transverse webs or ribs a, the whole being cast integral min a single piece. Saidjframe is mounted upon legs or standards A that are ing-lever, and Fig. 7 is a view of the handle H, .the treadle rods or'connections; I, the I boltedto suitable lugs or laterally-projecting upper front end are two vertical hearings or guideways,f, for supporting the striker-head F. The peculiar construction of this frame with the two webs A is afeatureof my invention, the purpose of which is to prevent the twisting springing of the frame by torsional strain occasionedwhen using the die under the extremefend of the striker-plate.

The block or cutting-bed B is made of woodin ordinary form, and rests upon a flanged metal plate, B, supported by four screws, 1), that pass down through the main frame A, and are pjroviddywith, geared nuts m, as indicated. Said" rewsare held tightlyat their upper ends inEthe plateBL The gear-nuts m severally mesh with the central gear, M, and the heightof the block is; gidjusted in the usual manner by revolving the 1 gear M and nuts m. For revolving the gear I, I employ a hen dle-lever, L, which is pivoted on the central stud of the gearM and projects at the front of the machine. Upon this handle is arranged a latch-lever, I, (see Figs. 4 and 7,) having a depending point that passes through the handlever and engages with the teeth of the gear a M for moving the gear when the handle is carried to the right or left. By pressing down the latch-lever 1 its point is released from the gear-teeth, so that the handle can be shifted for taking anew, hold. By this means the gear can be moved as required, either to the right or left, in a very convenient and easy manner.

The shaft C is mounted in bearings at the lower rear part of the frame A, with its crank between the webs A. At one end it is furnished with tight and loose pulleys O and at the opposite end with a large fly-wheel, C

The working-lever D is arranged between the webs A and is fulcrumed on the upper part of the frame at d, with its forward end over the striker F and between the guides, while 1 its rear end curves downward at the rear of trated. The forward end of the lever D is made with a suitable face or ofl'set, t, to engage the chock-piece or quoin I for forcing down the striker F, and with a suitably-rounded surface at the top for raising said striker.

The construction, location, and arrangement v of the driving-shaft and striker-lever mechanism are features of my invention, the purposes of which are to give greater stability-and less vibration by bringing the heavy moving parts nearer the base of the machine to give greater length of leverage; to continuously move the lever when the machine is in operation, and

. thus, by reducing the number of parts that require to be stopped and started at each blow, avoid loss of power and excessive straining on the driving parts; also, to obviate the necessity of an automatic clutch mechanism on the shaft-'a device which rapidly wears out and v is liable to frequent derangement.

The striker F is made with two guidingstandards, F, which work in the vertical guideways fon the head of the frame. Be-' tween these two guides is arranged a steel shoe, F having a semi-cylindrical cavity, which forms a seat for the heel of the swinging chockpiece or quoinI, which latter is pivoted between suitable ears extending upward from the sides of the shoe F as illustrated. The chock-piece and shoe are fitted to each other with a close-working joint. The shoe is secured firmly to the striker-plate, and the top of the chock-piece is properly squared and fitted to swing under and receive the end or face i of the depressing-lever D, whereby the striker is forced down for giving the blow upon the die for cutting the leather. The guides F, which are preferably of cylf'ndrical form, are joined at their upper ends by a bar or yoke, F, the ends of the pieces F being firmly fitted to the yoke and plate F by counterbored and shouldered seatings. v The parts are connected by strong bolts, F which extend through the interior of the cylinders F from the bottom to the top (see Fig.5) and clamp the parts securely together, so as to give a square rigid head-piece, with the guides F parallel to each other. By employing the guides F with the depressing devices arranged intermediate or between them the striker is caused to work straight and level, and is prevented from can ting ortaking an inclined position and cramping on the joints when the die is set under one end of the plate.

The balance-spring K consists of a series of flat leaves or plates seated upon and attached to the frameA in the manner illustrated. The end of the longer leaf is extended through an opening in the yoke or bar F or otherwise suitably attached for elevating the striker. The tension of the spring K ismade sufiicient to balance or retain the striker in elevated position, so that there is no liability of the striker descending accidentally and injuring the operator while placing the die, as sometimes occurs with machines of other construction.

The quoin I is swung to and from the de pressing-lever by the starting-treadle G, to which it is connected by the rods H H, one of which is pivoted to the side of the quoin and extends from these to an angle-lever, H, pivoted to the rear of the frame, while the other extends from said an gle-lever to the rear end of the treadle G, as shown in Fig. 2. Depression of the treadle Gr swings the top end of the qu'oin l beneath the end of the workinglever D, so that the face i engages the .end of the quoin and the striker F is depressed thereby. When the treadle is released it is raised by its spring G, and the quoin I is swung outward or away from the end of the lever D, so that the levei' passes it without actuating the striker.

The construction. of the striker with two guides, the balancing-spring, and the manner of operating the head by means of the swinging quoin or chock-piece in. connection with the working-lever, are features of my invention.

IIO

moving striker is intermittingly actuated by lever mechanism; but in such machines the construction and action of the devices are different from the improvements herein described.
