The present invention relates to av device.

for tightening the 'felly or rim of awheel on the spokes thereof, and aims to provide a novel and improved device vof this character which may be conveniently attached to a wheel without removing it from the axle ant will provide for efficiently tightening the felly on the spokes. I

Another objectof the invention is the provision of a wheel tig'htener as above mentioned which is adapted to swage the outstruck flanges of a metallic felly or rim to the reduced ends of the spokes extending through said outstruck flanges.

A further object of the invention is the provision of a tool which when arranged on the felly of a wheel will align the swaging members of the tool with an outstruck flange on the felly and hold-said tool in properposition on the wheel during the tightening or swaging operation.

A still further object of the invention isthe provision of means for supporting the tool against spreading or twisting movement durmg the swaging operation, as well as forming means for locking the tool to a spoke and on the felly of the wheel.

It is also an object of the invention to providea device of the above indicated character, which is simple and substantial in constructon, which can be manufactured economically, and which will be thoroughly eflicient and practical in use.

lVith the foregoing and other objects in view, which will be apparent as the description proceeds, the invention resides in the construction and arrangement of parts, as hereinafter described and claimed, it being understood that changes can-be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a front view of improved tool showingthe same arranged upona wheel, Figure 2 is a side elevation of the same,

Figure 3 is a horizontal section taken on line 8-3 of Figure 2,

Figure 4 is a perspective view of my improved tool, showing the same in position to be attached to a wheel,

Figure 5 is a fragmentary vertical section taken on line 5-5 of Figure 2, and

Figure 6 is a vertical fragmentary section taken on line 66 of Figure 1.

Referring to the drawings, thenumeral 10 designates the main frame or bracket, which consists of a vertical wall 11 from the ends of which project upper and

lower plates

12 and 13 respectively, forming a frame of substantially U-shape in formation, the bottom plate being provided with a longitudinal slot 14 extending inwardly from the free end thereof and of a width corresponding to the diameter of the spokes of a wheel. Mounted on the pper side of the lower plate adjacent the. vertical wall 11 by means of pivot pins 15 are locking plates 16 arranged so that when swung towards each other on the upper surface of the plate 13, said locking plates will come together at the center of the slot 14. Each of the locking plates 16 is provided at its inner edge with an arcuate notch 17, to form a circular o ening aligning withth'e slot 14 when the "p ates are brought together. The arcuatenotches 17 are countersunk, as indicated by the numeral 18 for a purpose which will be set forth, as the description Droceeds. v

Threaded through the upper plate 12 of the frame or bracket 10in alignment with the" notches 17 when the locking plates 16 are in contact is a screw-threaded rod 19 provided on its upper'end with an enlarged head 20 in which is slidably mounted a hand bar 21 for operating said screw-threaded rod. The lower end of the operating rod 19 is slightly reduced in'size, as at 22, to receive a swivel ed die or swage block 24 held on the rod by a set screw 25 engaging an annular groove 23 in said reduced portion of the rod. The swage block is cylindrical andprovided in s upper end with a socketto receive the lower end ofthe screw-threaded operating rod and inits lower end with a'c'avity tapered inwardly from the outer end thereof and of a diameter corresponding approximately with the out-struck flange 27 of the metal felly 28 of an automobile wheel for swaging said flange on the inner reduced end 29 of the spoke 30, the socket and cavity being separated by a partition 26.

Pivotally connected at the free end of the upper plate 12 of the bracket or frame 10 is a U-shaped bracing member or yoke 31, in the present instance pivotally connected to said plate by means of a crosspiece 36 welded or otherwise secured thereto and having upstanding ears 35 at its ends through which the pivot pin 34 passes, the outer sides of the ears being flush with the opposite side edges of the plate so that the

members

32, 32 of said yoke will straddle said plate, and the length of the yoke is such that the bight 33 thereof will pass over the outer ends of the bifurcated lower plate 13 of the supporting frame of the swaging device to brace the spaced apart

plates

12 and 13 during the swaging operation. The pivoted locking plates 16 have their upper surfaces slightly rounded at the opposite side of each, as indicated by the numeral 38, so that when a rim is arranged over said locking plates, the corners of said locking plates will not distort the rim during swaging of the outstruck flanges 27 thereon.

In operation, the device is arranged in the position indicated in Figure 4 of the drawings, with the U-shaped bracing yoke slightly swung upwardly and the pivoted locking plates swung outwardly away from each other so that the device may be easily and conveniently connected to the rim or felly of the wheel with a spoke thereof extending through the slot 14 in the bottom plate 13 of the bracket or frame 10. By then swinging the locking plates to positions so that the same contact with one another, the spoke which extends through the slot 14 also extends through the opening formed by the arcuate notches 17 of said locking plates. The U.-shaped bracing member is then swung downwardly to a position such as that indicated in Figures 1, 2, 3, and 6 of the draw ing to brace the frame as well as hold the pivoted locking members against swinging movement or out of engagement with the spoke. The hand bar 21 is then turn-ed so as to rotate the power screw 19, which will cause said screwto move downwardly through the top wall 12 of the frame or bracket until the swage block 24 engages the outstruck flange 27 around the reduced end 29 of the spoke. Further turning of the screw will swage the out struck flange on the reduced end of the spoke. It can be seen that by pro viding the annular groove 23 on the end of the power screw with the set screw 25 extending through swage block and into said annular groove the swage block is carried by the power screw, yet the same is not compelled to turn therewith during turning thereof.

- It is also to be noted that the end of the power the swage block so as to relieve strain on the screw. During the swaging operation, the U-shaped bracing member will prevent spreading of the upper plate 12 from the lower plate 13 of the frame or bracket and thus hold the device in proper position so that the same will function efliciently. The arcuate notches 17 in the locking plates 16 are countersunk at their upper edges as in many instances the shoulder on the spoke which engages the rim or felly at the inner side thereof spreads outwardly and will be received in the countersunk portion of the opening formed by the locking plates which will cause the pressure to be applied on the rim and not on the spread portions of the spokes. After an outstruck flange has been tightly swaged to firmly engage outstruck flange 27, the power screw is turned so as to disengage the swage block 24 from the outstruck flange and the U-shaped bracing member and locking plates are swung upwardly and outwardly respectively so as to permit removal of the device from the rim. By using the device for tightening each spoke of a wheel it will obviate the necessity of purchasing a new wheel when the rim becomes loose upon the outer ends of the spokes.

lVhile my device was especially designed for tightening the rim on the spokes of wheels, the same may be efficiently used in connection with'removing or pressing in bushings in bearings and may also be used for other purposes found desirable.
