" `MACHINE FOR RouNDlNG LEATHER.

` Application tiled March 10, 1853. (No model.)

.To aZZ whom it may concern:

Be it known that 1I, CHARLES W. ROGERS, a citizen of the VUnited States, residing at Baltimore, Maryland, have invented certain new and useful Improvements in Machines for Forming Leather Bound, of which "the follow- A ing is a specication, reference being had to i the journals of the rolls.

the accompanying drawings, forming part hereof, in which- Figure 1 is a front elevation of a machine embodying my improvements. Fig. 2 is a sectional view through the center thereof. Fig. 3 is a section through one end of the frame,the rolls being removed; and Fig. 4 is a plan view ofthe forked lever for adjusting the rolls.

`Like letters of reference indicate the same parts in all the gures.

The object of my invention is to furnishaset of rolls forthe purpose of completingthe filled or partially-filled round leather without recourse to hand-labor. v

In a former patent issued to me, numbered 251,293, and dated December 20, 1881, I show rolls for preparing the round leather, `theiinishing being done by hammering, which is a slow, tedious,` and expensive process. By my present improvement all hammering is `dispensed with, the leather coming from the rolls in a finished state. y y

To this end my invention consists in the construction, arrangement, 'and combination of parts, which will be first fully described here inafter, and then specifically pointed out in the claims.

Referring to the drawings by letter, AA are standards, fastened in any suitable manner to a frame or table, and which afford bearings for Ihese standards are longitudinallyslottedas at a, Fig. 3, said slots forming tlfe bearings for the lower roll, B, and by virtue of their length vertically admit of an adjustment -of .said roll toward or from the roll C, which is journaled in said standards above the roll B, and is not adjustable. That portion of the rolls B C which projects beyond the bearings is provided onone end with gear-wheels b c,to cause the proper simultaneous rotation ofthe rolls, and on'the otherV end with devices similar to those shown in my previous patent, A

hereinbefore referred to. That portion of the rolls within or between the standards is formed to finish the round leather, the upper roll, C,

assumes the form shown in Fig. 5.

having four ribs, c2, 013,0", and c5,which register lows: D is a standard located on the sameframe Y or table as supports the standards A A', and centrally therewith, and has projecting upwardly therefrom a standard, d, having its upper -end rounded to receive as a fulcrum a forked lever, E, having a main body, e, and three arms, e c2 e3, projecting `from said mai'n body on o ne side, and a central arm, e, pro-` j ecting therefrom in an opposite direction. The standards A A have each a lug, a2, and the arms e e2 e? of the lever E are notched at e5, to engage with the rounded top of the standard al and the lugs a2, said lever being support ed upon said standard and lugs. `The arm e4 is the handle for operating the forked lever, and thus raising the rollBinto operative position, andthe arm eisvextended beyond the roll, and lis provided with a suitable weight to cause it to fall when released, and thus allow the roll to drop to its inopcrativeposition. The arms e e3 have a bearing against the lower side of the journals vof the rolls.

b which are shown inm former atent and Fig. 6 showing it as formerly completed by y hand, but which I now complete with the machine. The roll c is provided with aknife, as shown, as is also the roll b, which serve to cut the channel in the folded strip to receive the stitches which bind said folded strip F and the filler-strip G together.

' In operating this complete machine I take the ordinary flat strip, prop erlycut and shaved to a` uniform thickness, and, folding it in U shape, pass it through the rolls c b, and when removed therefrom insert the iiller-strip G,

which is then secured by stitching through the e channels cut by the knives on said rolls and This product is then passed through the` rolls B C in channel b2b3 b4, as may be best suited to its size, and when it emerges therefrom it will be of the form shown in Fig. 5, after which it is brought .to the shape seen in Fig. 6 by being drawn IOO through a die or draw-plate, or in any other invention are obvious.

Dispensing with the hammering formerly necessary, much manual labor is saved, curtailing the time, and consequently the expense, as well as avoiding the irregularity of the hand -made product and the tendency to break the skin or body of the leather, which would involve the loss of the stock or the expense of skilled labor to repair. The product is always uniform in size, shape, and density, and, being rolled, no danger of abrasure is incurred. The roll B may be removed from or replaced in the standards A A by simply loosening the screw h and swinging the plate H downward on the screw h as a pivot, as shown in Fig. 3.

Having thus described my invention, what I claim, and. desire to secure by Letters Patent,

. l. The combination, substantially as described, of the rolls B and C, the formerbeing mounted in movable bearings andthe latter in I Iixed bearings, the roll B being provided with l grooves/b2 b3 b, shaper and channeler b, and suitable means for adjusting it, and the roll C, with rings or collars c2 0305 and theshaper and channeler 06, as and for the purpose set forth.

2. 'Ihe combination, substantially as described, of the rolls B and C, the latter having fixed bearings, with the standards AA', hav-
