HORATIO KEYES, OF TERRE HAUTE, INDIAN-A y' Letters Patent No. 99,913, dated February 15, 1870.

IMPROVEMENT IN MACHINE POR SMOOTHINGSPOKES.

The Schedule referred toA in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, HORATIO KEYES, of Terre Haute, in the county of Vigo, and State ot Indiana, have invented anew and improved .Spoke-Sn'oothing Machine; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled Ain the art to make and use the same, reference being had to the accompanying drawings forming part of this specification. i

r The ohect of this invention is to provide a machin y for rapidly and economically smoothing spokes for wagon wheels.

The invention consists of au improved arrangement of apparatus for slowly moving the spoke, held incenters at the ends lengthwise, along and turning it in contact with a polishing belt, moving rapidly across it, the said apparatus being guided by a pattern to move the spoke to or 'from the belt, according to the variations in the shape ofthe said spokes, so that the pressure against the belt will always be the same, and the effect thereby rendered uniform.

The invention also comprises certain means for reversing the movement oi' the spoke-carrying devices for moving the spokes longitudinally back and forth, also certain means for throwing the spokes out ot' contact with the belt at the end of each 4longitudinal movement, and for automatically stopping the longitudinal movements at the ends of the same in each direction.

Figure 1 represents a sectional elevation of my improved machine, taken on the line :c ot' iig. 2;

Figure 2 represents a top view with some parts partly represented in perspective; and

Figure 3 represents atransverse sectional eleva-tion, taken on the line y y, g. 1.

Similar letters of reference indicate corresponding parts. i A represents a mandrel, arranged in bearings B at the ends of arms C, having bearings at D, whereon they may osoillate.

This mandrel is provided with two. loose pulleys E F, a sliding-clutch, G, av sliding-frame composed ot' parts H I T, a toothed pinion, K, and a screwed end, L.

The clutch slides between the pulleys and is ysecured to the mandrel, as is also the pinion K, by a feather.

This pinion gears with the toothed wheels N O, which are on spindles I Q, borne by the cross-piece .H of the sliding-frame.

The .cross-piece I carries tail spindles R S, corresponding to the spindles P Q, and the two cross-pieces are connected by bars T.

The spoke to be smoothed is suspended between the spindles P R, and a pattern, U, having enlargements V W at or near the ends, is suspended between the spindles. Q S. The enlargement W is adjustable.

rlhis enlargement of the patternrests on the wheel l X, which revolves on a stud-pin projecting from the frame of the machine, and supports tbe mandrel A and its adjuncts, and governs the positions of the spokes relatively to the polishing-belt Y, working over the pulley Z, and having its surface provided with any rough or polishing material.-

total-y motion is imparted to the mandrel Ally the beltsA`1 A2, acting upon the pulleys E F and clutch G, one turning it one way and the other the other way, one belt working direct. and the other being crossed. The mandrel imparts motion to the spindles P Q, revolving them and the spoke and pattern slowly, at the same time that they are moved along bythe screwed end L of the shaft, screwing through the crosspiece I. i i,

lhe pattern is so shaped and arranged relatively to the spokes, that, working ou the wheel X, it will move the spoke tojor from the belt, as required by the varying shape .of the spoke, by raising the mandrel and arms c c or lowering the same, whereby the action of the polishing belt on the said spokes will be uniform. When 4the spokes have arrived at the end of their movements 'either way'it is desirable to move them entirely away from the belt, so `that when standing to be removed or set into the return movement, the belt will not act upon them unduly in'one place. This is effected by the enlargements Vaud lV of the pattern, which, ridingup to the top of the wheel X, as they are arranged to do, will raise the spokes entirely out of -the reach of the belt.

Guiding rollers B are arranged under the belt at of which work between pins a, proiecting'from the' vertically-sliding weighted bars F3 audh, which have notches b in their sides, into which spring-catches d, drop when the said weighted bars are raised, which is done by a sliding hand-lever, Gr', having cords G and 4Gr2 connected to it, and working over guide-pulleys in such a manner as to raise one bar while the other is down, and cioe corsa.

When the bar G1 is drawn out to the right and the bar F raised, the clutch will be moved into gear" with the pulley F, and the mandrel will be rotated in the direction to move the carryingframe and the spoke to the right, and when moved the other way the clutch Y will gear into the other pulley, and the opposite movement of the mandrel and spoke will take place.

VThe said lever G is moved by hand. To prevent the carrying-flame from revolving with the mandrel, a projection, H, from the cross-head H, works in a slot in the ba'r H2. Inl order-to prevent the cross-heads from being moved too far bythe screwed mandrel,it is desirable to stop the motion of the said mandrel automatically at the end of 4each movement.

This I accomplish by means Vof a sliding-bar, I', having pins-12 and I, arranged to strike the ends of the spring-catches d, whenthe bar is moved in the right direction, and disengage them from the bars FiI or F and allow them to fall, by which they will move the clutch G away from either oi' the pulleys E or F, with which it may be engaged, but not far enough to engage the other.

This bar I is moved at the proper time by the wheel o coming in contact with the pins K1 or K projecting into the path of the said wheel.

As represented in the drawing, the machine is in the position to move the carrying-frame to the right, which movement will continue until the wheel o strikes the pin K2, and moves the bar I1 far enough to the right to cause the pin -Ii to disengage the spring d fronrthe bars F, and let vit fall, by which the tilting bar 11" will be carried-down far enough to throw the clutch out of gear with the pulley F. -This will take place simultaneously with the raising of the enlargement V of the pattern upon the wheel X. The mandrel will then stand still until the slide-bar G is moved again in the opposite direction.

The tail spindle R is required to be moved quickly for the removal of the finished spoke and the insertion of another, for whichit is provided with an eccentric lever, L, and connecting-link L, so arranged that when the lever is turned down in the positionrepresented inthe drawings, to force the spindle up to the spoke, the connecting piece of the link will fall slightly below the pivot-pin f of the lever. and be thereby locked in that position,

Having thus described my invention,

I' claim as new and desire to secure by Letters Patent- 1. The combination of the 'movable frame H l TT, carrying-centers P. R QS, screw-shaft A L, sliding pinion K, spur-wheels N O, pattern V, and polishingbelt Y, all arranged and operating in the manner and for the purpose specified. l

2. The threaded mandrel A, arranged in bearings C C of the frame, in combination with loose pulleys E F, clutch-sleeve G, gearsK N 0, centers P Q, and nut I, the said parts constituting the feeding mechanism, and being constructed and arranged as described.

3. The pattern U, with enlargements V and W thereon, constructed as deseribed,in combination with the wheel X, the said parts operating to remove the spoke away from the belt at the end of each traverse, as set fort-h. l

4. The combination of sliding hand-lever G', cords Gr1 G, weighted bars 1? F, tilting-lever F1, tongue El, sliding-bar 1)', andshfter C', all operating together to ship'and unsliip the clutch in the manner specified. 5. The combination ot' sliding-bar I, having pins Iz 13, with wheel O, and pins K1 K, and the springcatches d, to limit the movement of the mandrel by throwing the clutch out of connection with both ot the pulleys, as setforth. f

6. The combination of the eccentric lever L, con necting-link L2, connecting-pin e, and the point-pin f, to operate the tail-spindle 1t, in the manner described.

HORATIO KEYES. Witnesses.
