AUTOMATIC SPOKE-TURNING I' IACHINE.

Application filed October 4, 1921.

To all #0720120 it may, concern Be it known that I, HENRY Fmcma citizen of theIlnited States, residing in the city and county ()fJlCl-ISOH, State of Michigan, have invented certain new and useful Improvements in Automatic Spoke-Turning Machines. of which the ttollowing is a specification.

This invention relates to an improved automatic.spoke turning machine. The objects of the invention are:

First, to -pro*.*ide such a machine which will from a previously prepared spoke billet turn out a complete finished spoke with a tapered head and the tcnon finishe l.

Second, to provide such a structure with an improved arrangement of cutter heads.

Third, to provide in such a structure an improved means for effectively turning the entire spoke.

I ourth, .to provide in .such an automatic machine an improved sander means.

Further objects and objects relating to details andeconomies of construction and operation will fdefinitelyappear from the .detaileddescription to follow. 7

, Q'Ihe objectsof the invention are accor plished by the devices and means described in the followingspecification. The invention isclearlydefined and pointed out in the claims.

A structure showing a preferred embodimen't oflthe invention is illustrated in the accompanying drawing t'orming a part of this specification, ,in which:

plates of thennain frame of the'machinewhicli suppo'rt and carry the ot her parts. A generalsupporting case4 is provided to embrace the central upper part of the side frame 2 and a similar supporting circular plate 5' is at the other end of the machine.

' f'zThe main supporting shaft "6 is carried in abearingT atthe center of the plate 5 and bearing '8 at'the center of platett'. A

cylindrical shell 9 isprovidedat the" center to which atthe leftlend se'ciire d the. head 10 and -a supporting plate 11 is parallel therewith and. secured thereto by an outer shell 11 ,This constitutes the holder. of. the lmu'lt'iple lathe spindle lieadsor headstock, the same being 'revolubly. supported on the shaft 6. A similar head 12is at the opposite end of the cylindrical shell 9 and carries the tail spin'dles'or centers.

The headstoclrs each comprise a spindle l3 carryingahead 14: which is provided...with

a thrust bearing 15 betweenitandthe plate 10. Thesame'is held securely. against-the thrust bearing 15 by the coiled spring 1.16.

7 Upon the head 17' at the outer end of the spindle 13 is a chuck comprising a pair of rollersv 18 18 transverse to the center forming the jaws for receiving the tapered or mitered hub end of a spoke. The spindle is 7 provided with a pinion 19 and is driven by Y a gear 20 keyed to the shaft 6 at 21, the

20 serving to drive all of the multiple:

spindles at the same time.

The tallstock comprises the sleeve 22 (see Figs. III and VIII) carrying the reciprocating center 23 which is secured against rotation; The sleeve is clamped securely by clamp 24. Abushing 25 is provided forthe outer end of the reciprocating member which is held pressed inwardly by the coiled spring 27. I Each tailstock is provided with a roller 25 which bears against the spring pressed ring 28 which is supported by a series of pins 29 having coiled springs 30 disposed thereon within the circular plate l.

A'cam 31 seen in dotted lines in Fi s.

III and IV andin full lines in Fig. VIII) I is provided for withdrawing the tailstock ca Ll 32 is the magazine for receiving the spoke billets-33. These are carried from the mag azine at the opening'3 l by being shucked and swung under the cutter heads, as lndr cated at 35,'rotat1ng on the lathe centers as ihey progress and being actedupon by the cutter heads. J u

The multipleelathe spindles of the machine are jdriven by the pulley 36 which is driven by the belt 37. The pulley 36 is on theshaft 38 which bears a worm 39 which drives a worm gear40 on shaft l1 which drives pinion a2 which meshes with pinion 43 on the main shaft 6 which, therefore,

drives the main shaft 6 at a relatively low. rate of speed and revolves the spindles at a relatively slow speed as they are advanced to the cutter heads and sander. The work carrier is revolved on its. axis from shaft 6. Secured to shaft 6 is a gear 44. which drives a train of gears 4:5, 46-and47. The

gear 47 meshes with gear rim 48(see Figs.

III and V) which revolves the multiple lathe work carrier uponits axis around the shaft 6. This causes the multiple lathe to revolve. around its center while the lathe spindles are being revolved on their centers as they are advanced. 1

The cutter head- 49' is provided with 7 blades 49 having curved end portions 50 corresponding to the curve at the inner end of a spoke, so that when a spoke swings to These tail position as indicated in Fig. IV, by the first round spoke 35, the cutter very .quickly reduces it to size while the'revolving spoke is passing.

The cutterhead 49 is carried on the shaft 51 which is supported in suitable shouldered

bearings

52, 53 to maintainthe same, against longitudinal displacement. These are driven by pulley 54. The pulley'55 at the outer end of the shaft drives the pulley 36 through the belt 37. I

- Between the blades d9 of the" cutter head are disposed angularly projecting saw like cutters 4:9 ver like the sections'of dado,

saw, which cut a'neck or annulus towards the outer end of the spoke, thus forming the spoke tenon. Further on, on the frame, is supported the cutter head 59 which is car-- ried on the shaft 58 which is provided with a pulley 57. An idler pulley 56 is provided 'on the frame between the pulleys 54- and 57.

Around these is disposed the driving belt 60. The cutter head 59 is provided with twice the number of knives as the cutter head 49 and it works'very rapidly and gives a smooth finishing cut to thespoke.

' Sander rolls 61 and 62 are supportedin proximityv to the path of the spindles beyond the cutter heads on suitable axes inthe frame. The roll 62 is carried on arm 63 pivoted at 64 for adjustingthe same. A

hand wheel 65 is provided for adjusting the same laterally.

Thesander rolls conform in their longitudinal outline to the contour of the cutter I The sander belt 66 is heads (see Fig. 'II). dr-iven'from the roll 67, the same being provided. with a'pulley 68f driven by thebelt 69 by any suitablemeans. The pulley is carried on the adjustably pivoted standard 70 on trunnion 71.

On a suitable base 72, adjustable by the hand screw 73 in threaded lug; 74; is the ten. sion weight structure 7 5 connected by pivot 7 6 through "rod 7 7 by the adjustab le nut 78 to the said pivotalstandard 70.]

In the operation of the machine, spoke billets 33 are placed in the magazine 32 and, when the machine is put-in motion, the first pair of spindles thatcome opposite the bot tom billet in the magazine is snapped very strongly by the tailst'ock into and between the

double roller chuck

18, 18, and is ad vanced revolvingon its own axis'to the cut-- ter head 49 which rough cuts the.,1nain body of the spoke in-its exact and proper relation to the tapered chucked ends The dado saws 4-9 out an annular groove forming the tenon of thespoke with a projecting piece of wood beyond the same (see illustra tion in the lower part ofFigQIII).

Thexrevolving spoke is their advanced to the cutter 59 which, owing to the fact that it has double the number of knives, cuts a very smooth finishing cut straight across the outer body and the button-like'projection at the end. The spoke then advances to the 'apidly traveling sander belt 66 which is held yieldingly' in contact with theturned body of the spoke, finishing the same, and after this sandingoperation the roller 28 on the, tailstock passes into engagement with the cam iil which gradually withdraws the tailcenter to the position indicated in 'FigLVIH, and drops the spoke with the button on the end of the tenon, which can be "thereafter cutoit'. The roller continues upon the cam until the tail spindle comes opposite the next succeeding billet in the magazine when the, process is repeated A cut-oft saw-tor the tenon may be provided in this connection.

'lhis structure can be greatly modified without departing fronrthe invention. A multiple structure is shown. The spokes could be turned and finished without forming the tenons and on the other hand the tenons=-1nigl1t be formed without the final finishing process, all to the advantage to the extent indicated. lathe with a single spindle andpair of rollers to properly dispose the cutting head could be made use of to make the spokes, and the dado saw for cutting the annular grooves could be made use of independent of the cutter. It is desired to claim the invention specifically and also broadly, as pointed out in the appended claims.
