SPOKE-FINISHING MACHINE.

SPECIFICATION forming part Of Letters Patent N0. 679,61 1, dated July 30, 1901.

Application filed April 11, 1901. Serial No. 55,318. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE A. ENSIGN, 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 Improved Spoke-Finishing Machine, of which the following is a full, clear, and exact description.

The invention relates to woodworking machinery; and its object is to provide certain new and useful improvements in spoke-finishing machines whereby the spokes are accurately and uniformly finished both at the throat and face without requiring the employment of skilled labor.

'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.

Figure 1 is a plan view of the improvement. Fig. 2 is an enlarged side elevation of the same. Fig. 3 is a front elevation of the same. Fig. 4c is an enlarged transverse section of part of the improvement,showing the driving-gear. Fig. 5 is an enlarged front elevation of the sand-band pulleys. Fig. 6 is an enlarged sectional front elevation of the spoke-holder and driving-gear for the spoke'holder sockets. Fig. 7 is a transverse section of the same on the line 7 7 in Fig. 6. Fig. 8 is a plan View of the locking-catch for the spokeholder. Fig. 9 is a face view of one of the sockets for the tenon of a spoke. Fig. 10is a front view of the tenon end of an unfinished spoke, and Fig. 11 is a like view of the tenon end of a finished spoke.

The spokeholderA is preferably provided with sets of tenon-sockets A and butt-sockets A for supporting at one time three spokes B B B of which the spoke B is a newly-inserted unfinished spoke. The spoke B is acted on by the endless traveling sand-band O to finish the throat of the spoke, and B is acted on at its face by a revoluble sand wheel or disk D to finish the face of the spoke after the throat thereof has been finished by the sand-band 0. (See Fig. 11.)

The spoke-holder A is mounted to turn and to slide bodily with a revoluble and slidable shaft E, disposed horizontally and carrying at its left-hand end a pattern F, abutting against a stop F, said left-hand end of the shaft being mounted to turn in a bearing G, mounted to slide in the direction of the length of the shaft E in guideways H, held on a plate 11, mounted to swing on the top of a bed-head I, mounted 011 the bed I of the machine. The plate H is f ulcrurned on a vertical shaft E, journaled in a bearing 1 on the bed-head I, (see Fig. 3,) and said shaft E carries at its upper end a bevel gear-wheel E in mesh with a similar bevel gear-wheel E having its hub mounted to turn in a bearing Gr, secured to the right-hand end of the plate H. The rightrhand end of the shaft E is mounted to slide in and to turn with the bevel gear-wheel E so that the shaft E is turned when the shaft E is rotated, and at the same time the shaft E is free to slide in the direction of its length, so as to shift the spoke-holder A and the spokes B B carried thereon, correspondingly and also permit the plate H to swing transversely on the top of the bed-head 1, according to the movement given to the bearing G and said plate H by the revolving pattern F abutting against the stop F, it being understood that aspring H (see Fig. 2) pulls on the plate H and holds the pattern F against the stop F. A synchronous sliding and turning motion is given to the shaft E by suitable devices actuated from a cam-shaft J, driven from the main shaft K, connected with the sand-band O, to impart a traveling motion thereto, the said main shaft K being also connected with the sand-wheel D to rotate the latter, and the said sand-wheel D is moved transversely to and from the spoke by mechanism actuated by said cam-shaft J, as hereinafter more fully described.

The main shaft K is provided with a pulley K, connected by a belt K with other machinery for rotating the shaft K, and on the latter is also secured a second pulley L, over which passes a belt L, also passing over a cone-pulley L mounted to rotate loosely on with a gear-wheel L fastened on a shaft L carrying a pinion L in mesh with a gearwheel L secured on the cam-shaft J, so that when the main shaft K is rotated the said pulleys L L the belt L, the pinion L the gear-wheel L, the pinion L and the gearwheel L will impart a reduced rotary motion to the shaft J. The shafts J, K, and L mentioned are journaled in suitable bearings on the bed I, and on the right-hand end of the shaft J is secured a bevel gear-wheel N, in mesh with a bevel gear-wheel N, on which is mounted to turn and to slide a shaft N connected by a universal joint N with a shaft N journaled at its forward end in a bearing 1 depending from a bearing 1 and on the forward end of said shaft N is secured a bevel gear-wheel N in mesh with a similar gearwheel N (see Fig. 3,) secured on the lower end of the shaft E, so that when the camshaft J.is rotated, as previously mentioned, a rotarymotion is given to the shaft E by the connection mentioned, and as said shaft E is geared to the shaft E it is evident that the latter is rotated from and at the same rate 0 speed as the cam-shaft-J.

On the cam-shaft J is secured a canrwheelg 0, having its cam-groove engaged by a friction-roller 0, (see Fig. 1,) journaled on one end of a lever 0 fulcrumed at or near its middle, at O on a bracket 1 attached to the bed I, and the other end of said lever O is pivotally connected by a link 0 with a col; lar O adjustably held on a rod 0 mounted to slide in suitable bearings 1 attached to the bed I. The right-hand end of the rod 0. carries a shifting fork O engaging a shifting collar 0 held on the right end of the shaft E, so that when the shaft J is rotated, and with it the cam-wheel 0, then a sliding motion is given to the said shaft E from said cam-wheel by the connection just described.

On the left-hand end of the cam-shaft J is secured a cam-disk P, against the peripheral surface of which abuts a shoe P, held on a rod P mounted to slide in bearings 1 attached to the bed I, and the forward end of said rod P has a swivel connection P with a rod P, carrying a shifting fork P engaging a shifting collar P held on the outer end of the shaft D, carrying the sand-wheel D. A spring 1?, connected with the rod P holds the shoe P in peripheral contact with the surface of the cam-disk P, and when the shaftis rotated, and with it the cam-disk, then a sliding motion is given to the rod P to shift the shaft P transversely in its bearings and move the sand-wheel D quickly in engagement with the face of the spoke to finish the said face and then to move it immediately out of engagement with the face back into an outermost inactive position.

On the maindriving-shaft K is secured a pulley Q, over which passes a belt Q, also passing over a pulley Q secured on the shaft 0, carrying a pulley 0 over which passes the sand-band C, also passing at its forward end over pulleys C C, having their shafts journaled in suitable bearings 0 secured on a slide 0 held adjustably by ascrew-rod C on guideways I on the bed I, as is plainly illustrated in Fig. 2.

By reference to Figs. 1, 4L, and 5 it will be seen' that the sand-band O can be readily slipped over the pulleys C C O to permit of conveniently changing the sand-band when it is worn out or a new one is needed or one of different quality is to be used for finishing the throats of the spokes.

The detail construction of the spoke-holder A is as follows: Each of the tench-sockets A is secured on a shaft A (see Fig. 6,) journaled in a head A secured to a sleeve A through which extends loosely the spoke-holder shaft E, and on said sleeve A is secured a head A, in which are mounted to rotate spindles A carrying the butt-sockets A Springs A press against the inner ends of the spindles A so as to hold the spokes securely in place in a set of sockets A A and at the same time permit the operator to push the socket A to the right when removing a spoke or placing a new one in position in the sockets A A The shafts A carrying the tench-sockets A, are rotated from the shaft E, and for this purpose the latter is provided with a gearwheel R, in mesh with gear-wheels R, secured on the shafts A so that when the shaft E is rotated the said gearing rotates the shaft A and the sockets A, and as the spokes B B B are securely held in said sockets A and in the sockets A it is evident that the spokes and sockets A rotate with the sockets A.

In order to temporarily hold the sleeve A and the heads A A from rotating, a catch S is provided adapted to engage one of a series of notches in a disk A forming part of the head A. (See Figs. 6 and 7.) The catch Sis pivoted at S on a bearing S held longitudinally adjustable on a flange H extending on the plate H in the direction of its length, as is plainly shown in Fig. 3, and said bearing S is adapted to be secured on said flange H by a setsorew S On the catch S is secured a handle S by means of a set-screw S and a spring S", held on the bearing S presses the catch S so as to engage the same with a notch in the disk A whenever the holder A has been turned by hand to bring the catch in register with a notch. By the operator moving the handle Stransversely the catch S is swung out of engagement with the disk A", so as to permit of giving one-third of a turn to the spoke-holder, and thereby bring a newly-inserted spoke in engagement with the sandband C and to bring another spoke that has been operated upon by the sand-band O in position for engagement by the sand-Wheel D, it being understood that the spoke-holder is turned by the operator in the direction of the arrow a, as indicated in Fig. 7

IIS

In order to cause the spoke-holder A to move bodily with the shaft E when the latter receives a sliding motion from the cam-shaft J, as previously described, the shaft E is provided with collars E E (see Fig. 6,) of which the collar E is adjacent to the gear-Wheel R, and the collar E is at the end of the head A. The collar Ementioned may be the hub of the gear-wheel R.

The stop F for the pattern F is in the form of a vertically-disposed roller journaled in a transverse bar F ad j ustabl y held in a bracket F attached to the bed-head -I, as is plainly shown in Fig. 2, and said bar is adjustable transversely by a screw-rod F", and after the desired adjustment has been made the bar is locked to the bracket F by a bolt The head I of the bed I can be adjusted to bring the spoke-holder A into an angular position relatively to the face of the sand-band O and also transversely adjusted to bring the spoke holder nearer to or farther from said sandhand 0. For the purpose mentioned the bed I is provided with a slide 1 adapted to be moved transversely bya screw-rod 1 and on the slide 1 is formed a pivot 1 engaging the head 1, so that the latter can be turned on said pivot and bodily moved transversely on moving the slide 1 Screw-rods I connect the slide 1 with the head I, so as to lock the head in place after it has been turned to the desired angular position on the pivot 1 The operation is as follows: Then the main shaft K is rotated, the spokes B B B are rotated and moved bodily transversely and longitudinally, owing to the action of the pattern F and the sliding motion given to the shaft E and the spoke-holder A thereon. The spoke B is now in engagement with the sandband C, and during the movement of said spoke B the throat B is abraded by the sand band, With the exception of the face B", as during the time the face approaches the sandband the spoke moves from the left to the right, so that the left-hand edge of the sand band gradually leaves the face B" and is at the end or point B of said face 13 at the time said face B faces the sand-band. The spoke B is now moved from the rightto the left, and as it turns at the same time the face B moves away from the face of the sandband C, so that the latter now abrades the throat on the opposite side of the face B without touching the latter. The sliding of the spokes is done very quickly, as will be readily understood by reference to the form of the cam-wheel 0 shown in Fig. 1. During the time this operation takes place the spoke B which had its throat already treated by the sand-band C in the previous operation, is engaged at its face B by the face of the sand-wheel D immediately previous to the beginning of the sliding of the spoke-holder, so that the said face'is abraded to give it a very fine finish, it being understood that the sand-wheel D is but a moment in contact with the face B", and consequently the slow then unlocks the spokeholder by moving the catch S out of engagement with the notched disk A, and finally turns the spoke-holder until the catch S engages the next following notch to again lock the spoke-holder against turning on the shaft E. The newly-inserted spoke has its throat now first finished at the sand-band C, while the spoke previously operated is now faced at the sand-Wheel D.

It is understood that the head A of the spoke-holder is adjusted on the sleeve A ac cording to the length of the spokes to be treated, and the head I is adjusted transversely and angularly relatively to the face of the sand-band 0, according to the thickness of the spokes and their shapes at the throat or tenon ends.

The catch S is made sufficiently long (see Figs. 3 and 8) to allow the sliding movement of the spoke-holder without disengaging the catch from the notched disk A As it is the duty of the operator to simply remove the finished spokes, place unfinished spokes in position, and periodically unlock and turn the spoke-holder, it is evident that no skilled labor is required to tend the machine. A large amount of finelyfinished Work is turned out by the machine in a comparatively short time.

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