SPECIFICATION forming part of Letters Application filed April Patent no. 300,280, dated June 10, 1884.

14,1834. (N0 model.)

To all whom it may concern:

Be it known that I, J AMES H. PARKER, a citizen of the United States, residing at Mil ford, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Machines for Compressing Heels of Boots or Shoes, and for other Purposes; and I declare the following to be a description of my said invention sufficient- 1y full, clear, and exact to enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

lhe objects of my present invention are to provide a pressing-machine for compressing boot and shoe heels, embossing pieces of leather, and for other similar purposes, which machine can be conveniently and rapidly operated; to provide an automatic intermittentlyacting feeding apparatus for carrying forward the material while the pressing-plates are sepa rated; to provide means for preventing the adherence of the stock or material to the surface of the pressing or embossing plate; also, to afford facilities foradjustment of the press to different thicknesses of stock and for difi ferentdegrees of feed action. These objects I attain by the mechanism illustrated and described, the particular subject-matter claimed being hereinafter definitely specified.

In the drawings, Figure 1 is a front View of my improved pressing-machine. Fig. 2 is a side view of the same. Fig. 3 is a plan View, the top part being in section below the head block, with dotted lines indicating the rela tive location of the head-adj usting gears. Fig. -l is a front view of the follower, with section of the feed-belt. Fig. 5 is a bottom view of the head-block and impressing plate or die. Fig. 6 is a sectional view on a larger scale, showing the detail of one of the discharging studs in the impressing-plate. Fig. 7 is aplan view of the feed-operating ratchet on larger scale, and Fig. 8 is a side view of the ratchet and pawl devices.

In referring to parts, A denotes the supportingframe, composed of two side castings j oined together by girts a, and containing suitable bearings for the crank-shaft B and operating-shaft O, which are disposed in the manner illustrated. Shaft- O is provided with tight and loose pulleys G for the driving-belt, and with a pinion, C", that meshes with and operates the gear B 011 the crankshaft B.

I) D indicate the standards or strain-rods, supported in upright position in sockets formed through the frame castings, and retained by set-screws d (l, or in other suitable manner.

E denotes the head-block, G the foot-block, and F the movable prcsser or follower, which latter is worked up and down by the knucklejoint arms H H, respectively seated and pivoted on the footblock G and follower F, and connected at their knuckle-joint to an arm or pitman, I, that extends to and is operated by the crank Z) of the shaft B, so that the arms H. H are expanded and contracted at each revolution of said shaft, therebyreciprocating the follower F and closing and opening the pressing-matrix. The foot-block G is arranged across the lower part of the frame on the rods D, and is held by nuts g on the ends of said rods, as shown. The top ends of the rods D are screw-threaded, and the head-block E is sustained thereon by suitable hangers, c, in connection with geared nuts 12, fitted on said screw-threads, and by means of which said head-block may be adjusted up and down the rods, as desired. The several nuts B are geared to a common central wheel, 13 by means of which all of the nuts E can be turned in unison when effecting the adj ustmcnt of the head.

K indicates an endless belt, apron, or traveling feed-bed supported on pulleys or rolls K and K at front and rear of the machine. Said rolls are mounted in bearings on brackets attached to the follower F, so that the feedbed moves up and down with said follower. The upper partof said follower may be furnished with a slightly yielding cushion or plate, L, made of hard felt or other suitable substance that will give a strong and sufficient support for impressing the work, but which will yield under ekccssive pressure, so as to prevent breaking the press in case of oversized or very thick material. The upper part of the traveling feedbed K passes across and trally in the follower F.

the gear, as shown.

rests upon the top of said cushion-plate L. The lower part of said bed K passes through an opening, f, arranged for that purpose cen- The bearings of the bed-supporting rolls are adjustable, so that proper tension can be given to the apronbelt K.

The journal of the rear roll, 10, is extended beyond its bearing, and is furnished with a gear and ratchet mechanism, N, which is coir nected for operation. by a rod, M, to a crank, M, on the shaft 13, and by means of such mechanism the traveling feed-bed or apron-belt K is automatically moved with an intermittent action for carrying the articles to be pressed into position beneath the impressing plate while the follower is depressed and the press is open. This ratchet mechanism is made substantially as shown in Figs. 7 and 8. A gear, N, having a flange or plate, N f xed'to its side, is arranged to revolve loose on the rollshaft K. A ratclietavheel, N, is keyed on said shaft in position to be engaged by a pawl, a, pivoted on the plate N, and pressed down by a spring, at", for taking hold on said wheel N only in one direction. The gear N is retated alternately in opposite directions by the action of the reciprocating rack m on the crank rod M. The rackis confined to the gear by a guide, m, that runs in a groove in the hub of The reciprocative action of the follower F and rack m, transmitted through and converted by the ratchet mechanism N, effects the automatic intermittent movement of the feed-beltK, and the parts are so arranged and adjusted that such feeding movement takes place at the proper interval of time, alternating with the action of the pressing devices. The cranks M may be ad justed for giving a greater or less movement to the feeding mechanism, as may be required for different classes of work.

P indicates the impressing plate or die, which is secured to the under side of the headblock E, to give the form or working surface for flattening, shaping, or impressing the ma terial or article treated. The face of the plate 1 may be made either plain, indented, engraved, or otherwise fitted, as required, for impressing upon the work such form, finish, or ornamentation as may be desired.

To prevent adherence of the material acted upon to the surface of the plate I, I employ a series of small spring-studs, S, arranged at intervals in the body of the plate, with their ends projecting from the surface, as indicated. Said studs may be made as shown in Fig. (5, the head of the stud anda pressure-spring, .9, being let into a recess formed in the plate 1 and loosely confined therein by a tubular screw-threaded plug, 1 in such manner that when the pressure is applied the stud S is forced up into the plate, so that its end is flush with the surface of the plate, and when the pressure is taken off the spring 5 projects the stud in the manner indicated, and forces any adhering material or article from the surface,

so that it will be discharged from the press by the movement of the belt or apron K. The bolt t, which connects the plate I to the head, serves as a center for the adjusting-gear E", and the hand-nut V upon said bolt serves for clamping both the plate P and the gear E in position. Impressing plates 1? of different form or with differcntly-ornamented surfaces can be used interchangeably in the machine, as desired, for different kinds, sizes, or patterns of work, and the machine can be employed for compressing heels, stamping or en'lbossing pieces of leather, and for other useful purposes, thus making a very convenient and desirable mechanism.

In the operation of my improved pressingmachine the heels or other articles to be compressed, embossed, or stamped are laid upon the traveling apron or bed K at the front of the pressers. The intermittent movement of the apron carries them beneath the plate 1?, while the follower F is depressed. The feed-apron K then stops, while the follower F is elevated to give the impression, and as the follower is again depressed the feed-apron again moves forward, carrying the said articles to the rear, at the same time bringing the next lay of articles into position to be acted upon by the follower, and in like manner continuing while the machine is operation.

\ Vhat I claim as of my invention, and desire to secure by Letters Patent, is

1. The combination of the frame A, the standard-rods D, supported therein, the headblock E, the foot-block G, the follower F, the knuckle-joint arms H H, the connection I, crankshaft B, and operating -shaft 0, with gears 13 O", and pulleys C, said parts being arranged and operating in the manner set forth.
