SPOKE-TENONING MACHINE..

SPECIFICATION forming part of Letters Patent No. 687,662, dated November 26, 19'01. Application filed May '7, 1901i. Serial No. 59,133. (No model.)

To cir/ZZ whom, t may concern.'

Be it known that I, CHARLES SEYMOUR, a citizen of the United States, and a resident of Defiance, in the county of Defiance and State of Ohio, have invented a new and lmproved Spoke-Tenoning Machine, of which the following is afull, clear, and exact description.

The invention relates to woodworking machinery; and its object is to provide a new and improved spoke-tenoning machine designed for the use of spoke, wheel, and wagon manufacturers to dress the ends of the spokes to fit the mortise in the wheel-hub, the machine being comparatively simple and dnrable in construction, very accurate in operation to insure uniform work, and arranged to handle large and small spokes and to cut either a plain tenon or to completely tenon, miter, and point a Sarven spoke during the passage of the spoke through the machine.

The invention consists of 'novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming-a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Fig. 14 isa like View of the finished spoke, and Fig. 15 is a plan View of the key-pinion for turning the cam and adjusting the miter-cutter of the..

cutter-head. 1

The tenoning-machine is mounted on a base A and a column A', secured on said base, and the spokes to be formed at their inner ends B2 with tenons B (see Figs. 13 and 14) are moved over the rims C C2 of a stationary hood C by reel-arms D D' and fingers E, so as to pass the 'spokes between and along the top guides F F' and the bottom guides F2 F3, so that the inner ends of the spokes B2 pass between cutter-heads Gr G' to form the tenons B, points B3, and the miters B4, (see Fig. 14,) the finished spokes finally dropping over the rear ends of the bottom guides F2 F8 upon a downwardly-inclined rack or chute X, from which the accumulated spokes are removed from time to time.

The reel-arms D D are secured to the outer faces of rim gear-wheels H H', mounted to vturn on annular bearings C3, integral with the Webs C4 for the rims C' C2, said annular bearings C3 being arranged concentrically land spaced inwardly from said rims, as will be readily understood by reference to Figs. 1, 6, and 7. The webs C4 are rigidly connected with each other` by a hub-like bar C5, and the rims C' C;2 are provided with feet C, bolted or otherwise fastened to the base A. The rims C' C2 are formed at the rear with cut-out portions C7 (see Fig. 4) for projecting the pinions I I' in mesh with the rim gear- Wheels II HQ respectively, said pinions I I' being secured on a longitudinally-extending shaft I2, having bearings C8 on said rims C/ C2, (see Figs. 4,) and also a bearing on the column A', as is plainly shown in Fig. 2. On one end of the shaft I2 (see Fig. 2) is secured a gear-wheel I3, in mesh witha pinion I4, secured to an intermediate shaft I5, journaled in suitable bearings at the rear of the column A-, and on said shaft I5 is secured a gearwheel I6, in mesh with a pinion I7, fastened ona shaft I8, likewise journaled in suitable bearings at the rear of the column A. On

the shaft IB is mounted to rotate loosely a pulley l, connected by belt with other machinery for rotating said pulley, and the latter is adapted to be connected by a suitable friction-clutch Ilo with the shaft I2 to rotate the latter whenever it is desired to run the machine. The friction -clutch 140 is under the control of the operator standing at the front of the machine, and for this purpose said friction-clutch is connected with a suitable shifting mechanism adapted to be worked by the foot of the operator, as indicated in Fig. l, to shift the friction-clutch, and thereby the pulley 19 in or out of gear with the shaft 12. When the shaft I8 is rotated, then the above-described gearing rotates the pinions I I and the gear-wheels H H' in unison to cause the arms D D' to move the spokes B over the rims C' C2, it being understood that the attendant in charge of the machine places one spoke after another upon the rims C' C2 in front of a pair of advancing arms D D', as will be readily understood by reference to Fig. 1. The arms D D' are secured to the outer faces of the respective gear-wheels HH', so that said arms project beyond the peripheral face of the rims C C2 to yreadily take hold of the spokes, as above mentioned, and shown in Figs. l and The fingers E,previously mentioned, only operate in conjunction with the reel-arms D D', and a finger forms with the corresponding reel-arm afork, between which is held the outer end of the corresponding spoke B. (See Fig. 3.) The fingers E have their inner ends provided with sleeves E', having polygonal bores engaging a correspondingly-shaped ring E2, so that the fingers E can be adjusted on the ring according to the thickness of the spoke under treatment, the fingers then being secured in place on the ring by a set-screw E2. (See detail view, Fig. 7.) The ring E2 is carried by pins D2, attached to the inner portions of the reel-arms D', so that the`peripheral face of the ring E2 abuts against said pins, as is plainly indicated in Fig. 3, it being understood that every other arm D is preferably provided with such a pin; but each arm may carry one, if desired.

One of the pins D2 (seeFigs. 3 and 6) is provided at its outer threaded portion with a nut D3 for engaging a washer E4 for clamping the ring E2 in place against a collar D4 integral with the pin D2, so that the ring E2 is held in place for the time being, and when it is desired to adjust the machine for different-sized spokes then the nut D3 is simply loosened and the ring E2 is turned on the pins yD2 to move the several lingers E nearer to or farther from the arms D', according to the thickness of the spoke. When the adjustment has been made, the nut D21's screwed up to cause the washer E4 to clamp the ring E2 in place, so that the several fingers stand the Same distance spaced from the reel-arms D D'. It is expressly understood that the reelarms D D' extend from the outer faces of the gear-wheels H H', and the latter are mounted in the space between the bearings C2 and the rims C' C2 to be completely out of sight and not interfere with the spokes as the latter are moved over the rims C' C2 by the arms D D'.

In order to hold the gear-wheels H H in position on the bearings, suitable retainingplates C9 are secured to the bearings C2 and project over the faces of the gear-wheels, as is plainly indicated in Figs. 3 and 7. From the foregoing it is understood that the driven gear-wheels H H', the arms D D', and the ngers E operate in conjunction with the stationary arms C' C2 of the hood Gand form the feed-reel of the machine for moving the spokes between the guides F F' and between the cutter-heads. The guides F and F2 eX- tend transversely in vertical alinement one with the other, and said guides are formed or secured to guide-brackets F4 F5, projecting sidewise from the guide-plates FG F7, of which the plate F6 lies in front of the plate F2, (see Figs. 4 and 5,) and both are mounted to slide vertically in a guideway K, held vertically adjustable in guideways A2 on the column A', the vertical adjustment of the guideway K being made by the operator turning` a screwrod K', mounted to turn loosely in the plate K and screwing in the top of the column A'. (SeeFig.4 TheplatesFandF7areconnected with each other and supported by an equalizing device for simultaneously moving the guides F F' from or toward each other to allow the guides to yield on any unevenness or roughness of the ends B2 of the spokes B and prevent binding of the spokes in the guides, the equalizing device also permitting of manually adjusting the guides by the operator to set the guides F F2 for dierent sizes of spokes.

The equalizing device consists, essentially, of links L L', pivotally connected with the upper ends of guide-plates F6 F7, the links being also connected with a lever L2, fulcrumed on a stud L2, secured to the upper end of the guideway K, said stud L3 being midway between the pivotal connections of said links L L' with said lever L2, so that when the latter is rocked a simultaneous sliding motion is given to the guide-plates F6 F7 to move the guides F F2 an equal distance toward and from each other. By the operator turning the screw-rod K' the guideway K is moved up or down, so that bolt-plates F6 F7, their brackets F4 F5, and the guides F F2 are moved bodily up or down with the guideway K to bring said guides F F2 in proper relation to the cutter-heads G G'.

On the rear end of the lever L2 is sWiveled a nut L4, in which screws a screw-rod L5, also screwing in a turnbuckle L2, to which is fastened one end of a spring L7, secured at its other end to the column A. By the operator turning the screw-rod L5 the nut L4 is moved up or down to impart a swinging motion to the lever L2, and thereby set the guides F F2 a desired distance apart, the distance corresponding to the thickness of the ends B2 of the spokes to be operated upon by the machinos. In case the yends B2 are rough or IOo lIO

somewhat unequal the guides F F2 readily yield, owing to the spring L2, connected with the screw-rod L5.

The guide F' is held on a bar N, carrying at its outer end a weight N' and fulcrumed at its inner end at N2 on the arm O' of a cam O, bolted to the guideway K and moving with the same when the guideway is adjusted, as previously explained. The cam O extends in front of the guide-plates F( F7 to hold the latter in position, as will be readily understood by reference to Figs. 3, 4, and 5. The fulcrumend of the bar N is provided with an upwardly-extending arm N5, through which extends loosely a bolt N4, secured in the arm O', the nut N5 of the bolt engaging the face of the arm N3, so that when the nut is adjusted the bar N and guide F' are swung up or down to bring the guide F' in proper position for the spokes. As the bar N is free to swing upward against the weight of the weight N', it is evident that the guide readily adjusts itself to any unevenness or roughness in the spokes. The guide F3 is located below the guide F' and is held transversely adjustable on a bracket P, held vertically adjustable on the inner face of the web C2 for the rim C2. (See Figs. 2 and-i.)

The stop-plate Q for the inner ends of the spokes to abut against when the spokes are placed by the attendant in position on the rims C' C2 extends transversely and parallel to the guide F2 and somewhat at the left thereof, and this stop-plate Q is provided with a longitudinal rod Q', adjustably held in a bearing F2, secured to or formed on the top guide F, the rod Q' being secured in place by a setscrew Q2 after the stop-plate is set to the proper position for the cutter-heads G G' to cut the tenon to the desired length. (See Fig. et.) The cutter-heads G G' are alike in construction, and each is provided with a cutter-head body G2, (see Figs. 8, 9, and 10,) on which are mounted a set of tenon-cutters R, a set of miter-cutters R', a set of pointingcutters R2, and a set of shoulder-cleaning cutters R3, all arranged in such a manner that when the end B2 of a spoke B passes between the revolving cutter-heads G G' then said end is dressed and the tenons B', the points B3, the miters B4, and the shoulders B5 are all accurately formed at one operation. Each set of cutters consists, preferably, of two cutters, and the cutters R R2 R2 are mounted in the usual manner on the body G2, while the tenon-cutters R' are each adjustably secured on theinclined top S of a carrier S by means of bolts R4, each carrier S being mounted to slide in guideways G2, formed radially on the face of the cutter-head body G2. (See Figs. S and 9.) A bolt S2, screwing in the carrier S and extending through an elongated slot G4 in the body G2, serves to secure the carrier firmly in place after the carrier is adj usted in its guideways G2. On the face of each carrier S, at or near the inner end thereof, are formed segmental teeth S2 (see Figs. 9

and 11) in mesh with a spiral rib S4, formed on the inner face of a ring-shaped cam S5, mounted to turn on the hub of the body G2, the cam being held in position on the hubby a retaining-ring G5, as indicated in Figs.8 and 9. The peripheral face of the cam S5 is provided with a gear-wheel S6, adapted to be engaged by a pinion S2 in the form of a key having a handle S2, (see Fig. 15,) adapted to beset in the body G2, as indicated in Fig. S. When the key-pinion S7 is'placed in position in one ofthe bearings, it is in mesh with the gear-wheel SU, and when the operator now turns the handle S8 then the pinion STimparts a rotary motion to the gear-wheel S6 and the cam S5 and causes the spiral rib S2 thereof to move the carriers S simultaneously inward or outward,according to the direction in which the key-pinion S7 is turned. Thus by the arrangement described the operator can move the carriers S, and consequently the tenoncutters R', outward or inward to cut the ends B2 and leave tenons of the desired thickness. When the adjustment has been made, the operator simply removes the key-pinion S7 from the bearing GG, it being understood that when the adjustment has been finished and the bolts S2 screwed up then the several parts are securely locked in position on the cutter-head body G2.

The cutter-head herein shown and described is not claimed in this application, but forms the subject-matter of a separate application tiled July 16, 1901, Serial No. 68,485.

The cutter-heads G G' have their bodies G2 secured on spindles G2 and GS, journaled in suitable bearings carried by saddles T T', vertioally adjustable on suitable guideways carried by the column A', the adjustment of the saddles being accomplished by the attendant turning screw-rods T2 T2, journaled in the column A' and engaging nuts on the saddles. A hand-wheel T4 is adapted to be locked to either of the screw-rods T2 or T2 to turn the same and move the corresponding saddle up or down to make the desired adjustment of the cutter-heads. On the spindles G2G8 are secured pulleys U U', respectivelyengaged by a drive-belt U2, connected with other machinery, for imparting a rotary motion to the pulleys, the spindles, and the cutter-heads to revolve the latter for the purpose described. The belt U2 also `passes under a tighteningpulley U2, (see Figs. 1 and 2,) journaled on a slide U4, mounted to move vertically in suitable guideways on the column A', the slide U4 being adjustable vertically by suitable mechanism, -preferably a rack and pinion, under the control of the attendan t; (See Fig. 2.) Y

The shifting device for throwing the clutch 110 in or out of gear with the driven pulley l2 consists, essentially, of a shifting fork J', (see Fig. 2,) secured on a rock-shaft J2, jour- IOO IIO

naled in the column A' and extending to the front thereof. On the front end of the rockshaft J2 is secured an arm J2, pivotall y connected with a rod J4, pressed on by a spring J5 for normally holding the clutch 11?., out of gear with the pulley. The rod is mounted to slide on a bearing or bracket J 6, secured to the base A, and the free end of the rod is adapted to be engaged by a treadle J7, fnlcrumed on the bracket .V7l and adapted to be pressed by the attendants foot to throw the clutch in gear and rotate the shaft I2.

The operation is as follows: When the machine is in operation and the operator places a spoke B in position on the rims C C2 and the feed-reel arms D D and fingers E carry the spoke forward, then the ends B2 of the spoke abutting against the stop-plate Q are finally brought between the guides F F2 and between the cutter-heads G GH, so that the several cutters thereon form the tenon B', the point B3, the miter B4, and the shoulders B5. rlhe finished spoke B is then pushed by the reel-arms D D along the rear ends of the guides F2 F3, and finally said arms and iingers move out of engagement with the spoke, and the latter is then pushed farther rearward by the neXt following spoke until the spokes successively drop over the rear ends of the guides F2 F3 upon the chute X, provided at its lower end with stop-pins X for retaining the spokes on the chute. When a desired number of spokes have accumulated in the chute, they are removed by the attendant.

From the foregoing it is evident that the various parts of the machine can be readily adjusted to dress spokes of different sizes, shapes, and lengths, and to form tenons of the desired thickness and length, it being understood that the spokes are dressed uniformly and with great accuracy.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1.
