SPOKE-TENONING MACHINE.

scares.

To all whom, it may concern:

Be it known that I, GUS AVERY, a citizen of the United States, residing at South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Spoke-Tenoning Machines, of which the following is a specification.

This invention relates to spoke tenoning machines.

One object of the invention is to provide a spoke tenoning machine embodying such characteristics that the carriage which carries the mechanism for operating the tenoning tool may be raised and lowered, as de sired, and wherein the carriage may have a forced feed in the direction of the wheel so that the operator of the machine has to pay attention only to the tenoning mechanism operating means.

Another object of the invention resides in the provision of a comparatively simple, inexpensive, durable and efl'icient machine for tenoning spokes of wheels and embodying among other characteristics means whereby the carriage and its tenoning element may have a forced feed operation and means whereby the carriage may be moved automatically against the forced feed movement.

A still further object of the invention is to simplify the construction and arrangement of the parts of the devices now commonly used for the purpose of tenoning spokes of wheels.

With the above and other objects in view, the present invention consists in the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes may be made in the form, proportion, size and minor details without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings :-Figure 1 is a side elevation of the invention. Fig. 2 is asectional view through the upper and lower tracks upon which the carriage of the machine is operated, illustrating particularly the means for adjustably supporting the carriages to show their operative connection with the tracks. Fig. 3 is an enlarged longitudinal sectional view of the invention. Fig. 4 is a top plan view. Fig. 5 is an end Specification of Letters Patent.

Application filed August 23, 1909.

Patented July 19, 1910.

Serial No. 514,163.

View. Fig. 6 is a plan view of the lower track upon which the carriage operates. Fig. 7 is an enlarged detail View illustrating the locking means to hold the carriage against the action of the force-feed for the carriage.

Referring now more particularly to the accompanying drawings, the reference character 1 indicates a frame provided with suitable supporting legs 2.

The character 3 indicates a base upon which the hub 1 of the wheel may be sup ported for the purpose of disposing the spokes 5 in proper position for tenoning purposes.

In the present invention there is employed a carriage which is movable backwardly and forwardly and which when released from its locked position is adapted to have a forced feed toward the wheel. The carriage embodies U-shaped or channeled sills 1 1 and 15, webs 27 and 28 and spaced

links

6 and 7 and 8 and 9. The links 6 and 7 cross each other intermediate their ends and at their points of intersection they are pivotally connected together at 10, the links 8 and 9 being pivotally connected in the same manner. The links 6 and 8 are fixedly secured at 12 and 13, respectively, to the sills 14L and 15, with their free ends provided with lateral rounded offsets forming bearings 16 adapted to travel in the channeled or U-shaped tracks 17 and 1S, fixedly secured to the frame 1 by means of metallic strips 19 or in any other suitable manner. The opposite ends of the links are also rovided with lateral rounded offsets 1G acapted to slide in the sills and the tracks.

By virtue of the pivotal connection 10 between the arms 6 and 7 and S and 9, the carriage may be raised and lowered because of the laZy-tong-like connection between the sills and the track members, the track members being fixed against movement and the sills being permitted to move toward and away from the track members by reason of the

link connections

6 and 7 and 8 and 9.

Mounted upon the vertically adjustable carriage is illustrated a tenoning bit 21 carried by a spindle 22 upon which latter is a beveled gear 23 designed to mesh with a beveled gear 24, mounted upon a shaft 25, upon the ends of which latter are secured the operating handles 26. The tenoning bit 21 may be readily removed and a boring or rimming tool or any other tool may be substituted, and it will be understood that the spindle upon which the tool 22 is mounted, together with the

beveled gears

23 and 24 and the operating handle 26 are immaterial as regards their construction and arrangement, the essential feature of the present in vention residing .in the carriage and the means for mounting the same for movement toward and away from the wheel.

Connecting the lower ends of the links 7 and 9 is a connecting web 28, while connecting the lower ends of the links 6 and 8 is a connecting web 27, these connecting webs 27 and 28 being provided with

apertures

29 and 30, respectively, the aperture 30 of the connecting web 28 being screw threaded for a working fit with the screw threaded inner end of the operating screw 31, whose outer end is formed at 32 to receive a wrench to permit of rotation of the operating screw 31, the rotation of which will cause the connecting webs 27 and 28 to move toward and away from each other according to the direction of the rotation of the screw and accordingly raise and lower the carriage, that is, move said links on their pivots and raise and lower the sills 14L and 15 toward and away from the

lower track sections

17 and 18 for the purpose of alining the tool 21 with the spokes 5 of the wheel, as will be readily understood.

J ournaled in the outer ends of the

track members

17 and 18 is a shaft 33 which is provided with a groove 34: adapted to receive the springs 35 secured to the carriage for the purpose of holding the latter outwardly away, from the spokes of the wheel against a forced forward feed superinduced by a weight 36 connect-ed to which latter is a cable 37 passing over a pulley 38 and connected to the downwardly directed arm 39 which has connection with the depending arm 40 of the carriage, whereby, when the springs 35 are disengaged from the groove 34 of the shaft 33 by simply elevating the weighted arm 41 secured to one end of the aforesaid shaft 33 to turn the latter to throw the groove 34 out of cooperative relation with the springs 35, the carriage will move forwardly toward the wheel under what may be truly termed a forced feed, as hereinbefore stated. Then the weighted arm 11 is released, its weighted end 42 will throw the same to its downward position by gravity and consequently revolve the shaft 33 to its normal position so that when the carriage is forced backwardly against the weight 36, the springs 35 will automatically engage in the groove 34 in the shaft 33.

The character 43 indicates a foot lever fulcrumed at 44 in the

support

43, 44 and 44 and having its upper end 39 connected at 31 to the downwardly depending arm 40, which latter is fixed to the carriage, as

already stated, and by virtue of which connection and upon depression of the foot lever or treadle, the carriage will return to its normal position against the action of said weight 36 and cause the springs 35 to automatically engage in the groove 34 of the shaft 33, as already stated.

By virtue of the forced feed of the carriage all the operator has to do for tenoning or boring or other purposes, is to operate the handles 26 of the tenoning or boring mechanism.

In a spoke tenoning machine, a frame, a carriage including sills and supporting links, a tenoning mechanism supported on the carriage, tracks upon which the carriage is movable, the ends of all of said links sliding on the tracks and the free ends of certain of the links being pivotally secured to the sills and the upper ends of the remaining links being free to move on the sills.
