f LEATHER-maldiveMACHINE.

To all 'whom t may concern."

Be it known that 1,'FRANK F. SLocoM, a citizen of the Unitedv States,fresiding in the city 4andl county" of Philadelphia, State of Pennsylvania, have invented a new and useful Leather-Staking Machine, of which the following isia specification.' f Y My invention consists of an improved atf tachment for leather-staking machines.

It further consists of an improved means for adjusting the leather-engaging means of the upper jaw of such machine.

It further consists of improved means for taking up wear ofy the journals of the rollers in the upper jaw.

It further consists of other novel features of construction, all las will 4be hereinafter fully set forth.

` The annexed drawings and the following description setforth in detail one mechanical formembodying the invention, such dev tail construction being but one -of various mechanical forms in which the principle of the` invention lmay Ibe used. i In said annexed drawings 2+' l f Figure 1 represents a side elevation of as much of a'leather-staking machine `as will illustrate the application'of my invention'.

granted to myself and James Craig onMay ann-1898.' Y Referring tothe drawings, the reference numeral 1 indicates the frame lofthenia-` chine having the reciprocating'upperand lower jaws, 2 and 3,' which need not'b`e described, being the same as those illustrated and described in said above patent. The machine vhas the usual breast-roll,'4,`-and two staking-blades, 5 and 6,' are supported, upon the lower jaw, one adjustablein its rel'ationrto the other, longitudinally of the machine, by adjusting screws, 7, or` other means.- f f j y A T-shaped bracket, 8, has two longitudi-A nal slots', 9, in its fiat shank, through which pass adjusting and'fastening' bolts, 10f,pass` ing through the "outer end of the upper jaw and having nuts, 11, and washers,'12, for clamping the shank of thebracket to the under-side ofthe upper jaw. *Two perfo`v rated ears, 13', project downward from the side-edges of the flat; shank. f Thev endsof the transverse fhead` of thev bracket have slots, 14, and guide-recesses, 15, :are formed in the under-sides of saidv ends."'=y Conical bearings, 16, have screw-threaded sockets, 17', upon their uppervsid'es,V and rectangular. flanges, 18,1upon 'the upperfe'nds` voffsaid sockets are movable i'n the guidelrecesses. Screw-bolts, `19, pass 'through theslotsf` in the cross-head and into thesocketto'ladjust the bearings transversely to the jaw and lto thel machine. A roller, 20, has vconicalfjournals, 21,' which fit and turn in the conical bearings, and wear onfsaidf journals and bearings may be taken up by adjustingthe bearings and theirA bolts in the slots in the' cross-head. l f

A bracket, 22,'has its shank forked: to

form arms, 23,' having longitudinal slots,

24, through which passes a bolt, 25 having av nut, 26, andv which bolt also lpasses through;

downward and is formed with a cross-head 22", inclined to the vertical plane and formed with slots, 27,' inits ends and with rectangular 'guideerecesses, 28,` in the forwardly and downwardly facing side. Coni-4 cal bearings, 29, similar tothe bearings 1.6 in the first-described bracket, 'have' screw# threaded sockets,-30,` and re'ctangular` flanges movable in the guide-recesses. Screw-bolts, 31, pass through the slots in the inclined cross-head and into the sockets upon the bearings. A roll, 32, is journaled with its conical journals, 33, in the latter bearings.

A screw-bolt, 34, forming an adjustable abutment'is threaded in a perforation, 35, in the cross-head of the upper bracket and bears with its end in a step, 36, upon the lower bracket. Y

In Figs. 8, 9 and 10 is illustrated a slightly different form of my invention, in which the lcross-head, 22X, of the lower bracket is bent down into a vertical plane and a blade, 37, secured to the forward face of said cross-head by means of screwbolts, 38, and a clamping plate, 39, the bolts passing through such clamping plates and through kvertical slots', 40, in` the blade, into the cross-head.

The tension members for exerting tension upon the skin to be staked,-the rollers in the form illustrated in Figs. l to 7, included, and the roller and blade of the form illustrated in Figs. 8, 9 and 10,-and by means of which the skin is more or less flexed over the blades according to the relative proximity of the means to each other and to the blades of the lower jaw, being adjustable longitudinally upon the upper jaw, admit of the flexure of the skin over the edge of the staking-blade being adjusted to a greater or less degree, whereby the staking action A upon the skin is increased or decreased.

under side.

Thisadjustment, as well as the longitudinal adjustment of the blades upon the lower jaw, also admits of the elements being accurately adjusted according to the thickness of the skins to be staked.

As the operation of a staking machine is well known, it is not deemed necessary to enterinto a detailed description of the same. As the open jaws advance forward, the skin is inserted between them, whereupon they close and move rearward, dragging against both sides 'of the skimthe rollers against the upper side and the blades against the When the jaws arrive at the rear extreme of their reciprocation, they open and move forward, again grasping the skin when they arrive at the forward extreme of their movement. The operator holds vthe skin against the rearward drag of the jaws by clamping it between his body and thebreast-roll, and shifts its position when the jaws are open.

Any wear on the journals of the rollers or their bearings may be taken up by moving the bearings inward, toward one another, so that the rollers will run true and cause the blades to act uniformly on the skins, which is of great importance in staking skins on a machine to insure uniformity of the texture of the skins.

In Fig. 1l is illustrated a slightly different form of the upper bracket 8, illustrated in Figs. 1, 2, 3, 4 and 6, the bracket having its T-head upwardly inclined to provide oblique adjustment for the roller instead of straight vertical.

Other modes of applying the principle of my invention may be employed for the mode herein explained. Change may therefore be made as regards the mechanism thus disclosed, provided the principles of construction set forth, respectively, yinthe following claimsare employed. c

Having thus described my invention, what I claim as new and desire to secure by Let.- ters Patent, is
