\ `;A,\in the accompanyingdrawing,is the mainframe of the machine supporting the .xedhorizfontalwaya ai, a, uponwhich the carriage, B,rests. `The carriage, 1B, is furp `fnished withal fixedhead, C, anda movable fhead, D, which areffurnished withdogs, c, ,and d, between whichfthe piece `of stutlQF, to `.beoperated upon, isheld.` These dogs are of 2 f cylindrical form"for the "greater portion of .their length, and areboth in line. The dog,

i *0, `hasa headl of suchforrn, that it will not allow the stuff `to turn independently of it,

" e anditfis `furnished `with a spur wheel, n which gears withanother `spur wheel b', of similarsize,on a shaft, E, vvhichlisv arranged Vlongitudinally in the carriage, and furnished with handle, ,to turn it, and thereby turn the dog, cl `The handle, e, is made flexible, and; furnished `with a pin, f, on its inner "iwvoholes` (not shown) in the end of' the fearriage, and thereby holding the shaftsev cure from turning, and" also securing `the dog, @,Wand the` stuff. Thecarriage, B, is; furnished `with profile plates, g, g, whose..

,outeredgesare of the proper form, to direct the lateral movements of thecutters tocause ,i them togivepfthe `desired longitudinal pro-V filetofthe sides, and other profile plates, g',

gf, whose upper edges are of the proper form to direct the vertical movements of the cutters, to cause them to give the rdesired longltudlnal `profile to the top and bottom of the article to be produced, all bolted to the sides of the'carriage. At about the middle of the `length of the carriage, there is a transverse shaft, G, which works in bearings in the sldes, and is furnished with a broad crank, G', which is `capable of being turned upwards to form arest 0r support for the stuff midway between the dogs, and prevent it bending. This shaft is furnished outside the machine.` This frame is bolted `firmly to themain framing, and carries two gates,

J, J', which swing freely side by side on the horizontal transverse pivots, j, j, by which they are attached to thecutter frame. The gate, J, has suitable bearings, lc, k, to receive a horizontal transverse shaft, K, which `carries a series of cutters, L; and the gate, J has bearlngs, Ic, z,`to receive a horizontal shaft, K,which carries a series of cutters, Both these shaft-s are free to move to a certainfextent longitudinally in their bearings, and are attached by loose, arms, N, N, to rods, M, and M, which are parallel with them, and slide longitudinally in bearings in theirrespective frames. Thesev rods are so connected withthe shafts as to move longi.

tudinally with them, and are surrounded by coiled springs, l, Z, which are so applied to them as to force the shafts toward the cen` ter of the machine.` The rods, M, M', have arms, m, m', which hang downward, and these arms are forced bythe springs, Z, Z', into contact with the profile plates, g, '9, on the.V carriage, `The Gates are also providedwith screws, 0,0 which work in femalescrews in their front ends, and have their points protruding through the bottom,

and resting upon the profile? plates, g, g

1 The cutters are of suchform that the figure i'described by therevolution of either set will `have a profile of which the'part farthest from the center of the machine, corresponds in form to one quarter of the transverse Section of the rounded part of the spoke, and then extends toward the center of the machine in a straight line. This is shown in Fig. 4, where the profiles described' by the revolutions of the two sets o f cutters are shown. Those parts of the profiles between n, n, correspond in form with one quarter of the rounded part of the spoke and the parts between n, o, are straight. The gate, J, is made longer than the gate, J, in order to bring the cutter shaft, K, in advance of that K, and allow the two sets of cutters to work clear of each other. In rear of the gates, J, J, there is another horizontal cutter shaft, P, which `runs in fixed bearings in the standards, H, H, and carries a disk, P, furnished with cutters p, p, which cut sideways. This cutter shaft is allowed to move longitudinally to a certain extent, in its bearings, and is connected by a loose arm, Q,

with a rod, R, which is parallel with it.

y tudinally together.

This rod is allowed to slide longitudinally in bearings in the standards, H, and is so connected to the shaft, that both move longi- It has a coiled spring,

g, appliedto it in such a way as to push it another arm, r, which is held at suitable V, on the main shaft.

times by the spring, g, in contact with the curved edge of a plate, s, which is attached to the carriage, B.

The movements of the several cutters and the carriage, 'B, are all derived from the main shaft, S, which receives rotary motion from any prime mover, through a belt leading to the driving pulley, T. The swinging cutter shafts, K, K, receive rotary motion from the shaft, S, by means of belts, u, u, see Fig. 1 which run from pulleys U U, to pulleys, U, U, on the said cutter shafts. The tension of these belts serves to hold down the swinging gates, and keep the adjusting screws, O, O, in contact with the profile plates, g, g. The cutter shaft, P, receives rotary motion through a belt, lv, running over its pulley, V', from a pulley,

The carriage, B, receives a backward motion on the ways, a, a, in the direction from right to left of Figs. 1, and 2, to carry the Stuff in contact with the cutters, from a small pulley, W, on the main shaft from which a belt, w, runs to a pulley, t, on a-shaft, X, at the front end of the machine. This shaft carries another pulley, Y, from which a belt, y, runs to a pulley Z on a shaft, Z, which carries a pinion, 5, gearing with a spur wheel, 6, on ashaft, 7, which carries a pinion, 8, shown dotted in Fig. 1 gearing with a rack, 9, under the carriage. The shaft, Z, has one end supported and running in a bearing in a lever, 10, which is moved up and down to throw the pinion, 5, in and out of gear. Then the pinion Ais to be thrown in gear, the lever requires to be raised, and the lever is then supported on a step on a spring, 12, which is also attached to a shipper lever,

'13, moving horizontally on the top of the shaft, X, to a pulley 16, on` the shaft 7.

The pulley, 11, is loose on its shaft, and is coupled and uncoupled by an arrangement of mechanism, which is not visible in the views which are shown of the machine, and

which being unimportant, is not in any i' other place represented.

The operation of cutting a spoke is conducted in the following manner. The carriage is run out to the front end of the may, chine, the stud secured between the dogs,

c, d, and the. rest, G, brought up to support it. The main shaft is then set in motion, the pinion, 5, thrown in gear with the wheel, O, and the wheel, 11, uncoupled from the shaft, X, The cutters then receive rapid rotary motion, and the carriage is slowly moved backwards. When the stuff first arrives under the cutters, L, L, both these sets of cutters are forced away from the center l of the machine, by the pins, m,m, and profile plates, g, g, and only the straight parts, a, n, of the cutters are allowed to come in contact with the stuff, as shown in Fig. 4:, and plane the top flat, as the first part which is acted upon is intended to form the shoulder of the spoke; but as the carriage moves on the pins, m, m, are allowed by the plates to approach the center of the machine, and the curved parts of the cutters come into operation. the movements of the cutters laterally to the stuff, and the ways, g, g, direct their vertical movement, and thus regulate the form The profile plates, g, g, direct 'I of the longitudinal proileof the stuff. l rThe curved parts of the two sets of cutters plane the upper half of the spoke, each set of cutters planing one quarter. lOne side of the shoulder is planed by the cutters, p, p, on the disk, P whose position is regulated by the arm, r, and the profile plate, s, which theshipperJever, and sets free the lever, 10,ywhich `f l `and lets the pinion, 5, Voutof gear and@ ereby` stops the carriage. The attendant,,then,byjmeans of theproper t mechanism, couples fthe pulley, l1, .with the y `shaft,`X,andthelcarriage returns quickly forward;` iW'hen `the carriage stops, the handle, e, `is turned half way round,

` bringsfthe unfinished part to the top. The Lattendant `next raisesf the lever, 10, and

brings fthe pinion,"5,in1 gear withthe wheel, O, and thecarriageruns backlagain, and causes the; half of thestuif now uppermost,

i tofbe submitted tothe same operation as was "3 performed on the "other half during the y previous backward movement of the machine, andthe opposite side of the part which first arrives at the cutters, vto be a squared oifby the cutters, p, p. The spoke l `is now complete,` and when the carriage has u runrforward,` it `maybe taken out, and another piece ,offstuff inserted between the dogs. The operation of `cutting anyother article,

they pmperlmdiusted, @ms ifi Contact which turns the stuff half wayfround, and

is conducted in a similar manner V,to that of cutting aspoke. The diferencein form is produced by using cutters andprofile plates of different form.

This machine performs its work very perfectly, owing to the cut being made lengthwise ofthe grain of the stuff, in which respect it differs from most machines now in use for cutting similar articles. Y

i `Having thus fully described the nature lof our invention Ywhat we claim therein as new and desire to secure by letters patent is- The dressing of spokes by means of f a series of revolving cutters whose edges present an oblique profile in part of the spoke, whensaid cutters are so arranged on their shafts as to reduce the spoke in narrow longitudinal sections, by which means much more smooth work is obtained than when the cutters reduce `the spoke at one single operation as set forth. l
