UNITED STATES PATEN T OFFIC.
WILLIAM BUTTERFIELD, OF BOSTON, AND BRADFORD STETSON, OF UXBRIDGE, MASSACHUSETTS, ASSIGNORS TO THEMSELVES AND ELMER TOWNSEND.
MACHINE FOR SKIVING BOOT-COUNTERS.
Specification of Letters Patent No. 17,608, dated June 16, 1857.
To all whom it may concern.'
Be it known that we, WILLIAM BUTTER FIELD, of Boston, in the county of Suffolk, and BRADFORD STErsoN, of Uxbridge, in the county of Worcester, State of Massachusetts, have invented an Improved Machine for Skiving Counters to be used in Manufacturing Either Boots or Shoes; and we do hereby declare that the same is fully described and represented in the following specification and the accompanying drawings, of whichM Figure 1 denotes a top view of the said machine as it appears with its upper feed rollers folded or turned back or away from being directly over those with which they cooperate. Fig. 2 is a top view of the machine showing the upper feed rollers as turned forward or directly over their fellows. Fig. 3 is a longitudinal and vertical section taken through the feed rollers. Fig. 4 is a transverse and vertical section taken through the middle of the machine. Fig. 5 is a top view of a skived counter. Fig. 6 is a transverse section of it.
In these drawings, A exhibits the table or frame of the machine, the same being rovided with a driving shaft B exten ing through it, as shown in Figs. 3 and 4. On one end of this shaft is a crank C, for imparting rotary motion to the shaft.
To the frame A, or standard E projecting upward therefrom, two levers D D, are hinged or jointed at one end of each so as to be capable of being turned, vertically on their fulcra. These levers are united together at their other ends by a cross bar F. A horizontal shaft G, has its bearings in and is arranged in the levers, as shown in Figs. l, 2, 3, and 4, and gears H, I, are fixed respectively on the shafts B, and G, and so that when they (the said gears) are in engagement the revolution of the driving shaft will communicate a similar rotary motion to the other shaft. Feed wheels K and K1 are firmly fastened on the two shafts res ectively in the positions as shown in the dprawings, they being made to operate in connection with a straight knife L, and a pressure s ring M, arranged as shown in Figs. l and 3.
he lower feed roller is not entirely cylindrical, but a portion a, is so formed, the remainder being frusto-conical or made with a curved taper form as shown at b, in Fig. 3. This latter part bends up the leather when brought in contact with it and enables a straight knife, instead 0f abent or angular one, to be used. This affords an advantage in constructing the knife, as well as keeping it in order. On the upper shaft another or movable feed roller N, is placed and` should be so applied that it may be moved'longitudinally on the shaft and fixed in any desirable position thereon. For this purpose the shaft is formed with a groove c, extending lengthwise through it. A key or piece of metal f, is placed in this groove and extends into a similar one made in the hub of the feed roller. Against this key a set screw, g, screwed into the hub acts. While the key causes the roller to revolve with the shaft, the screw serves to fasten the roller firmly to the shaft. By loosening the screw, the roller will be free to be moved longitudinally on the shaft nearer to or farther from the upper feed roller as occasion may require.
Beneath the feed roller N, and applied to the shaft B, in the same manner as said roller N, is to its shaft is another or fellow feed roller or bearing made in all respects like the roller K, on the same shaft, but arranged with its tapering part standing in a direction opposite to that of the other roller. Another straight knife O, and a bearing spring P, operate in connection with the second or adjustable set of feed rollers, such knife and spring being sup orted by an adjustable carriage or plate (S, which extends across and on the frame A and is fastened thereto by clamp screws R, R, and thumb nuts S, S, the screws extending through parallel slots V, V, formed through the top plate of the table, as shown in Figs. 1, 2, and 4. By such means the plate Q, may be moved either toward or away from the plate T, of the stationary knife as occasion may require. Both of the lates Q, and T, are curved on their inner e ges, and these serve as guides for the passage of the counter through the machine while such counter is being chamfered or skived.
In operating with this machine the ieee of leather to be skived is introduce between the guides and underneath the pressure springs and so as to enter between the two sets of feed rollers. The drivng shaft being put in revolution and a weight or pressure being applied to the bar F, so as to press the levers downward, and force the upper feed rollers down upon the leather,
such leather will be borne against the knives secondary or adjustable feed rollers and and so as to have its two opposite parallel edges chamfered down as shown at x, x, in. Fig. 6. By sk iving tWo opposite edges of 5 the leather at one and the same time the machine can perform more than double ifnot quadru le the amount of Work, in a given time, t at can be accom lished When but one edge is chamfered, W en the leather is 10 run through a machine of the ordinary kind.
What We claim as our invention is- The combination and arrangement of the skiving cutter With the driving and feeding shafts and the primary or stationary feed 15 rollers and skiving cutter, the Whole being made to Operate as specified.
In testimony whereof, We have hereunto set our signatures WILLIAM BUTTERFIELD. j
