To 0 whom it may concern.-

Be it known that we, JOSIAH MENTOR GIM- SON, engineer, residing at No. 100 New Walk, JOSIAH GIMSON, engineer, residing at No. 14 Highfield street, ARTHUR JAMES GIMsON, engineer, residing'at North avenue, Clarendon Park, and SYDNEY ANSELL GIMsoN, engineer, residing at No. 20 Globe street, in the borough of Leicester, England, subjects of Her Britannic Majesty Queen Victoria, have invented new and useful Improvements in or Relating to Machinery Employed in the Manufacture of Boots or Shoes, of which the following is a specification.

This'invention refers to improvements in or relating to machinery employed in the manufacture of boots and shoes for stamping or cutting out by the aid of suitable knives, dies, or cutters, and known asdying-out machines. Hitherto such machines or presses have been constructed with a vertically-reciprocating bufier moving continuously up and down, the movement of said buffer being slow enough to allow the operator to slide underneath it when at its highest point a block carrying the material on which is placed the cutter or die, when at the next descent of the buffer the material is cut by the die or cutter, and after each operation the block, with thematerial, die, and cutter, must be moved away before the whole of the material has been cut, whereas by the means and devices herein contained the buffer remains stationary at its highest point and may be caused to descend very rapidly by the depression of the foot-lever. Therefore by the present invention it becomes only necessary to place underneath the buffer a blockwith the material to be out upon it. The operator can then with safety move the die or cutter over the material and for the whole surface or extent of the buffer-plate without having to move the block or the material. Said machine is designed with the following special advantages: To increase the speed of working, so that the output may be greater; increased wearing-surfaces, with a reduction in the working parts; also, avoiding the use of toothed gearing, besides giving greater security and rendering such machines safe to the operator. These objects are attained by the mechanism illustrated in the accompanying drawings in which Figure 1 is a side elevation of-the machine, the broken lines indicating that two machines can be coupled together without any difficulty and form what is known asa tw0 ended machine or double-ended press. Fig. 2 is a front elevation cut oif below the movable table; Fig. 3, a side view of the footlever; Fig. 4, a-sectional view on line m, Fig. 1; and Figs.'5 and 6 show the jawed lever, the divided and elongated rod, and sleeves in their normal and operatives positions, respectively.

Similar letters and figures refer to similar parts throughout the several views. I

' The maehineis known and employed either as a single or as a double ended press, the latter being obtained by making the frame of one uniform pattern or model, as shown, the compound balance-wheel A and driving-pub ley 1 working both parts of eccentric shaft or shafts 2, said balance-wheel A being made in two parts, (see Fig. 1,) one half being rigidly fastened to the end of the driving-shaft of one frame and the other half to the end of the other shaft, upon which are the fast and loose pulleys 1 and 1. Both the frames B can then be bolted up together, the balance-wheel A secured by screwing the two parts together (indicated by the letter 6) thus forming the duplex or two-ended machine known as a double-ended press.

At or near the top of the vertical frame B is mounted the horizontal driving-shaft 2 in the bearing 0 and carrying the compound balance-wheel A, the driving-pulley 1, and loose pulley l Upon the front end of the shaft 2 is the arm D, depending from the eccentric E, set out from the said shaft. Below this is the bracket (1, set out from the front of the frame to carry the buffer F, which is held upward by the springs G, arranged on each side of the bufier-head.

From the side of the head of the machine and parallel with the driving-shaft 2 is the small shaft I, carried in the lugs i. The front of said shaft carries the J -shaped lever J, connected to the eccentric-arm D by the spiral spring 7.9, the back of said shaft carrying the jawed lever L, set out at right angles from the machine. Into the jaws of this lever is fitting within the sleeve'O, which is rigidly fastened to the upper portion of the rod M by the pin passed therethrough and through the rod, the lower portion of which is free to slide in the sleeve 0, the pin 0 being driven rapidly through the top of the rod, and proj ects through two slots 0 cut in the sleeve 0. Over the sleeve O'is mounted the open spring 0 which is held up to the pin 0 by the nut 0 screwed onto the lowerend of the sleeve 0.

When the foot-lever 3 is depressed and the arm or driving-bolt D strikes against the stop P, the rod M becomes elongated and causes the spring 0 to be compressed into the operative position, as seen in Fig.6, Sheet 1. The further movement of the drivingshaft will then cause the arm or driving bolt D to rise until it is above the stop P, when the spring 0 becomes released and opens out, as seen in Fig. 5, thus causing the armor driving bolt D to be brought over and rest upon the stop P, when the further movement of the eccentric-shaft 2 and the arm or bolt D in moving downward forces the buifer F with it to the full extent of its movement. Upon the operator releasing the foot-lever-3 the springO, secured to the frame and to the jawed lever N, contracts and immediately causesthe jawed levers and rod to assume their normal positions, as seen in Fig. 5, Sheet 1, which places the driving-bolt and buffer in the position as seen in Fig. 4, Sheet 2. The springs O, as before stated, serve to keep the buffer up against the eccentric arm D on its return movement.- When the buffer arrives nearly at the top of its movement, the said arm D will again leave thestop P and be drawn across again toward the 'J -shaped lever J by the spring 70 and the foot-lever spring O A bracket, or by preference the movable table Q, is mounted in the slot q, situated on the front of the frame 13, which said table is eccentric E set out from the driving-shaft,

said arm engaging with a butter F with buffer-plate f, return-springs G secured to buffer-bracket d, a side shaft I carrying the .lshaped lever J with spring is in connection with the swinging arm or bolt D, jawed levers L and N set out at right angles to the frame B and pivotally connected to the divided vertical rod M, elongated by the depression of the foot-lever 3 and spring 0 said rod carrying a sleeve 0 rigidly fastened to the upper portion of the rod M by the pin 0, open spring 0 and nut 0 arranged and operating in the manner and for the purpose substantially as described-.- I

In witness whereof we have hereunto set ourhands in the presence of two witnesses.
