zenof the United States, residing at Punxsutawney, in the county of Jefferson and State of Pennsylvania, have inventedcertain new and useful Improvements in Wrenches for Wire-Spoke N ipples, of which the following is a specification, reference being bad to the. accompanying drawings.

his invention relates generally to Wrenches and particularly to wrenches peculiarly designed for unscrewing thenutsor nipples on the spokes of wire wheels.

In wire wheels, the spokes are operatively engaged with the hub and at their outer ends have screw-threaded engagement with screw-threaded nipples which extend through the rim to tighten the spokes. In-

asmuch as the spokes are very close together, it is difficult to use an ordinary wrench or use pliers for the purpose of unscrewing or screwingup the nipples and one object of my invention is to provide a nipple wrench of such construction that it may be used these confined spaces.

gain where ordinary wrenches or pliers are used for the purpose of screwing up. or unscrewing these nipples, the plier or wrench has to be removed from the nipple after each partial rotation so as to take a new hold at a newplace because of the fact that the wrench cannot be rotated within the space between 'twoadjacent spokes and,

therefore, a further object of my inventionis to provide a wrench which will grip the nipple or grip the spoke so tightly that the wrench will be held in place on thespoke and nipple so as to permit the hand tobe removed and a new I hold taken ongthe wrench after a certain rotation thereof.

A further object of the invention is to provide a wrench of this kind which may be forced upon a nipple which has had its facets damaged and still another fobjectis to ,provideawrench so designed that it may be used to rotate the nipplesfof the two "spokes adjacent the valve stem which pro- 7 ects through the rim of the'wheel.

Other objects will appear of the following description. A My invention is illustrated] in the accom pany'ing drawings, wherein A Figural is a perspective view ofoneform of my wrench showing it in applied position or the removal of 'anipple? in the course Specification of Letters lfatent. .Application filed January 17,

Fig. 2is a longitudinal sectional view of he wrench in applied position;

Fig.3 is a section on the line 33 of Fig. 2; Fig. 4 is Fig. 2; 7

Fig. 15 is a side elevation ofanother form my invention; face view thereof looking a section on the line 4=4: of

Fig. 6 is a toward the ends of the legs;

Fig. 7 is a section on the line in the direction of the arrow;

Fig. 8 is a longitudinal sectional view of another form of wrench;

Fig. 9 is an inside face view thereof; a longitudinal sectional view of still another form; and

Fig. 11 is a face view thereof. The form of my device shown inFig. 1 comprises a strip of metal 10 preferably about 5,.- of an inch thick and relatively narrow. This strip is longitudinally slotted intermediateits ends as .at ll. At one end the strip is formed with a longitudinally extending tapering open-ended slot 12 and at its other end witha relativelyshorter tapering The strip is bent upon itself intermediate its ends as at 14 and the ends of the strip are rebent as at 15 and 7 7 looking 1 6. There is thus formed two legs or termi- " nal portions 15 and 16, one relatively short and the other (16) relatively long. The leg or terminal portion 15: forms the wrench circumstances, that is it leg which is intended to The portions 14: and '16 constitute together the handle whereby the wrench may be rotated upon the spoke a.

In practical usethe wrench is disposed on the spoke a as in Fig. 1 with the spoke several slots 11, 12 and 13 and the walls of the slot 12 (or the is theslotl3 in this walls of the slot 13) engage with the many sidcd head of the nipple b. The wrench may then be rotated on the spoke to unscrew or screw up the nipple. It will be seen from Fig. 3 that the slot 11 is very slightly inclined to or oflset from the slots l2and- 13 so that the. spoke is slightly dee wrench is disposed upon the spoke and this causes the wrench to bind on the spoke so that it will not fall off but will remain in any rotated position onthe spoke. Thus it is notnecessary to remove the wrench after the nipple .30 v bent atits ends. to form a relatively long has been turned. a certain degreebut the hand'of the'operatoris simplyremoved from the wrench and then replaced and another turn given to theavrench. This is obviously particularly convenient under the circunr stances and it will be seen that the handle 7 of the wrench has practi ll a th somewhat in, diameter,

that they will driven onto the nipple by blows of a hammer, and under these circumstances the side I 'walls'oi the slot13 or the slot 12 will form leg 16 to the the space between two or new flat sides on a worn nipple. It will further be seenlthat' inasmuch as the wrench as a whole tapers from the relatively long relatively short leg 15 the device accommodates itself to the form of three adjacent spokes of the wheel.

In Fig. 5 I show another form of my invention which is equally advantageous and which embodies the same principle as the form shown in Fig. 1. This second form also consists of a strip of metal 17 which is leg 18anda relatively short leg 19. The

leg I8 is f0rmed with a tapered open-ended slotBO and the leg 19 is formed with a tapered open-ended slot 21., The strip of metal is longitudinally slitted and then the whereby the will bear against st p 2 two halves of the strip on each side of the slitted portion are bent in opposite directions as at 22 and 23, so asto form a handle v wrench may be rotated and so that the portion 23, which is slightlyin- 'clinedto theslots 18 and 19 orofifset ,withjrelation tothe centers of the slots 18 and 19,

the spoke and aiiord with the wall ofthe slot 2l a three-point-bearing' holding the wrench fromaecident'al rota tion. The operation of this second form-of wrench is precisely the same as that of the ,form illustrated in Fig. 1.

' In Fig. 8 I show another form of wrench embodying the same principle and this wrench comprises a strip of metal 24; bent so as to, form a relatively long le 25 and a relatively, short leg 26, the shQrtIeg having a tapered open-ended slot 27 and the long leg a taperedopen-ended slot 28. In order to provide for the three-point bearing upon the spoke, I strike out from the body'of the a tongue 29 which tongue is bent downward and then upward so that it intersects a line intersecting the'inner ends of the slots at two points. It will be noted, both in Figs. 3 and 5' that the loop 14; and the loop 23 intersect at. two points aline dra n fr m th in er ends o thesle st clinary enc f m slightly offset of a t ip Qii ing formed with 'a long'slot and a short slot r Fig. 10 I illustrate another forrniwhich is" simpler thanthe forms previously described but which doesnot have the threemust depend for its holding power upon being wedged onto the spoke and nipple. In this construction the strip of metal is angularly' bent so as to form the legs 33" and 34.

The leg 34: is formed with the tapered slot 35 and the leg 33"with the tapered slot 36. This form of wrench is ,operatedinqprecisely the same manner ias the forms previously tdescribed. V p l g 1 o ll, who ar engag in h epa loi bicycles, notorcycles and certain forms of automobiles,the need of a wrench; of the character described is ob vious, particularly in viewof the necessity of removing ani orengagernent with the nipple after the nipple has been turned a certain predetermined amount. 7 It willbe seen that my wrench is very cheaply made, very convenient in use andit has been found thoroughly effective in practices Having described my invention what I claimisg' 1, A wrench comprising abody formed' oi both of said iec ing n tll s d ctiem tapering inwardly, extending leg z i e open ended'slots, the middle of the strip be middle of the body havin a portion;intersect ng a l nec nnectingin r end of .116 1 i he ge qof aid rtionflb in from the plane of the slots.
