Application filed July 27,

To all whom it may concern. V

' Be it'known that 1, JOHN Morr MoRsn, a citizen of the United States and a resident of Syracuse, in the county of Onondaga and State of New York, have invented a certain newv and useful Spoke-Nipple Wrench, of which the following is a specification. 7 V a This invention has for its object a particularly simple, compact and eficlent wrench for turning the spoke nipples of wire vehicle wheels, bicycle and motorcycle wheels.

Therinvention consists in the novel fea tures and in the combinations and constructions hereinafter set forth and claimed.

. In describing this invention, reference is had to the accompanying drawings in wh ch like characters designate corresponding parts in all the views.

Figure l is an elevation of a wrench embodying my invention, the contiguous parts ofthe felloe and wire spokeof a wheel and the nipple, being also shown.

Figures 2 and 3 are central vertical secional views, the felloe being omitted, Fig.

2 showing the position of the parts before gripping the nipple and Fig. 3, after the wrench is tightened on the nipple.

Figure 4 is a vertical sectional view on line H, Fig. 7 the spoke, nipple and felloe This wrench comprises an outer tubular member or body 1, and an inner member 2 having a passage for the spoke, and means as jaws 3 for gripping the nipple 4, the inner member being rotatable in the outer member which has means coacting with the jaws to effect the tightening of the jaws, and both members having lengthwlse spoke receiving slots arranged to be brought into alinement to receive the spoke and nipple before the jaws are tightened and to be out of alinement when the jaws are tightened on the nipple.

As here illustrated, the inner member comprises a base 5 which threads into one end at 6 of the other member, andthe aws 8 are spaced apart prongs pro ectlng from the base 5, the prongs having inclined or conical faces 7 at their ends which engage the complemental conical walls at the other end of the body 1 during turning of the inner member into the outer, and tighten the jaws on the nipple 4. 1

8 is the lengthwise spoke receiving slot in Specification of Letters Patent.

' the body or outer member, the slot extending the full length of the body and opening through both ends thereof and also through the periphery and bore of the body.

9 is the spoke receiving slot of the inner member, it being formed in the base 5 thereof and opening through the outer end and periphery thereof and being of such depth as to extend past the axial center line of the inner and outer members. The slot 9 at its inner end is in line with the space 10 between the jaws 3. The inner member is provided with a suitable handle 11.

In operation, the space 10 and slot 9 of the inner member are normally in radial alinement with the slot 8 of the body when the jaws are unclamped, so that the wrench can be placed on a spoke with the nipple between the jaws. The outer member is then turned, thus tightening the jaws on the nipple and moving the space 10 and slot 9 of the inner member out of alinement with the slot 8 so that the spoke is completely enclosed and the wrench held concentric with the spoke. The wrench is then turned by turning the body and the inner member as a unit about the spoke, the body being formed with a suitable handle as a knurled this purpose.

What I claim is:

l. A spoke nipple wrench ner and outer members, the inner member having means for engaging the spoke nipple and being rotatable in the outer member, and the outer and inner members having lengthwise spoke receiving slots arranged to come into and out of radial alinecomprising inment upon turning of the inner member in the outer member, substantially as and for the purpose described.

2. A spoke nipple wrench comprising an outer tubular member and an inner clamping including opposing spaced apart jaws, the outer and inner member having coacting means to clamp the jaws when the inner member moves axially into the outer member, the outer member having a spoke receiving slot extending lengthwise thereof and opening into the bore of the outer member and through the periphery thereof, and the inner member having a lengthwise slot in line with the space between the jaws, the inner member being rotatable in the outer to bring the space between the jaws and the slot alined with such space into and out of alinement with $116 Sl t of the outer men);

box, substantially as and for the purpose specified.

3. A spoke nipple wrench comprising an outer tubular member and an lnner member including a base threading into onerend of jaws, andiopening into the bore of the in ner member and through the periphery thereof, the base of the inner member having a lengthwise slot in the line with the space between the jaws and arranged to be brought into and out of 'radi'al'alinement V with the slot of the outer member substan- .tially as and for the purpose set forth.

In testimony whereof, I have hereunto" signed my name, at Syrcause, in the" county of Onondaga, and State of New York, this 5th day of July, 1921.

JOHN MOTT MORSE.
