To all whom it may concern.-

Be it known that 1, A. A. WILDER, of Detroit, in the county of Wayne and State of Michigan, have invented a new and Improved Machine for Making Hoops for Barrels, Gasks, Ste.; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompany-4 ing drawings, making a part of this specification, in which- Figure lis a side view of my invention. Fig. 2 is also a side view of the same opposite to that shown in Fig. l; Fig. 3, a plan or top view of the saine.

Similar letters of reference indicate. corre spending parts in the several figures.

This invention consists in the employment or-use of two circular saws placed on one mandrel, m cnnection with feedroll'ers and' a pressure-rol ler and a curved plate, all arranged in such a manner that the timber from which the hoops are formed may be sawed of a unii'orm width throughout its entire length, and the timber then racked or divided into hoops, the whole work being done simultaneously or at one operation.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

' A represents a framing, which may be constructed in any proper way to support the working parts of the machine; and Bis a mandrel or shaft, which is placed transversely on the framingA and has two circular saws,G C, secured upon it, the space between which is equal to the desired width the hoop-timber is to be Cut.' On this mandrel B there is also placed a driving-pulley, D, and another smaller pulley,E. Ihe two saws O C work or pass through two slots, a a, in a horizontal plate, F, which vis secured to the framing-A. This plate F has two guides, G er, attached to it, the space be tween which is equal to the space between the two saws (J C. The form of ,these guides is shown clearly in Fig. 2. On the back part of the framing A there are secured vertically two metallic plates, H H, one at each side, and in i placed loosely a pulley, I, which is driven from i the pulley E on the mandrel B by means of a belt, J. The' pulley I is connected to the-shaft d by means of a clutch, K, which is adjusted by a lever, l, the latter extending to the front end of the machine, so as to be within reach ofthe operator or other attendant. (See Figs. 2 and 3.) The shaft d' also has a. pinion, e, upon it, which gears into atoothed wheel, f, on the shaft c', the .latter shaft also having a pinion, g, upon it, which gears into a pinion, Il., on the shaft e directly above the sha-ft c and from the pinion h motion is communicated to all the other shafts, b b d, by a train of pinions, t'. (See Figs. 2 and 3.)

On the shaftsb, b', c, c', and d, at the ends opposi te to those which have the pinions attached, there are placed tinted rollers j,j, k, 7c', and l (see Fig. 1,) and justbelow the `fluted rollerlol' the shaft d there is a curved pla-tc, M, which is attached the framing A by means of two setscrews, m m, the latter passing through two slots, a a, in a plate, o,'to which the plate M is attached.

The two shafts b chave a crossbar, N, fitted on them,in which saidshafts are allowed a weight, Q, suspended to one end of it. A lever,It, is also connected to the shaft d of the tluted roller l, and said lever also has a weight, S, suspended at its end. The bearings p of the shafts b c d in the plate li, which adjoins the iiuted rollers j' lo l, are open at the top, so as to admit of a vertical play or movement of said shafts.

The operation is as follows: The timber or `bolt T from which the hoops are made is got out in proper form beveled or tapered at one end, and checked or slitted, the number of slits corresponding to the number of hoops re quired to be racked or split from the timber. The timber or bolt T is then shoved between the two saws C G, which cut it of a uniform width, the bolt as it passes from between the saws passing between the guides G G and then between the iuted rollers j j k k', the latter serving as feedrollers and drawing the .timber or bolt Ialon g between the saws and also forcing the former between the roller land the curved plate M, the timber or bolt being racked or split into hoops at this point. The pressureof the roller l onthe timber or bolt to rotate freely, and the crossbar N is con# neeted by a rod, O, with a lever, P, which has is obtained 4by the weight S on lever B and the pressure of the rollers j lo on the timber or bolt is obtained by the weight Q on lever P.

From the above description it will be seen that the timber or bolt is sawed of aY uniform Width its entire length and racked or split into hoops at one operation.

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

1. The two saws C C and guides G G, in combination with the iuted feed-rollers jj k kQall arranged as and for the purpose speciiied.

2. The luted racking-roller l and curved plate M, or its equivalent, for the purpose sci; forth.

3. The saws C C, in combination with the Auted feedrollersjj k k', racking-roller l, and

curved plate M, all arranged substantially as and for the purpose specified.

4. Sawing or otherwise bringing to a uniform width hoops or timber for the same, and

racking or dividing it at one operation.
