'. Be it; known that I, Josiah mama, a resident of "Bellevue, in the county of Allegheny and State "of Pennsylvania, -5 new and useful' lmprovem'ent in Oil-Well SwivehWrenche's; and'I do hereby declare the following to be a full; clear, and exact descrip- "tion thereof. 7 -My' invention relates to tools-for handling ididrill-bits or other tools used in'drillingor operating Artesian wells and for like purposes, my tool. also being applicable in general ,tothe :handlingof any parts'to be screwed together when in a vertical position whether in con- ,15'nection with Artesian wells or any other mechanical operations, It is an improvement on PatentNo; 561,305, dated June 2,1896,

, issued to me and is intended to meet a'difliculty in the. useof tools for handlingheavy, 23%v parts required to be screwed together, owing to the amount of power necessary to unscrew or screw together such heavy parts. My invention consists, generally stated, in

1 ,providingthe rotary tool-holder with a handle 5 or handles whereby it may-be turned in the swivel-rmgand so arranging. the parts that said handles will not interfere'with the proper rotation of the tool-holder'even ifthe lever .isin an inclined POSltlOD.

This wrench 'said,'.1'in'g ,prepatent above referred to, and

In the use, of prior devices of this character" the wrench portion or tool-holder 7 has not 7 been providedwith a handle orlever for turn- One of the difliculties in the way of applying such handle-or lever is due 7 to the fact that the lever 1 in actual use is sel-- dom in a horizontal position,- but, on the contray, is usually inclined, and inasmuch as the handle or lever to be effective,mustproject "outwardly or radially with reference to the wrench or tool-holder the lever. 1 will be in the path of movement of such outwardly-rpro- 1 jecting handle, and'consequently will prevent the rotation of the same. Y'By my'invention vI provide the tool-holderwith a suitable oute wardly-projecting handle or handles 9, and sof arrange the latter that the lever 1 will notinterfere therewith, even when in an inclined po-. sition. I accomplish this by hayin said handle or handles depending from the to lholder I that is,.1'n ojectingdownw ardly t0aconsiderable distance before they are turned outwardly shown in the drawings, where the handles have a comparatively straight downwardlyprojecting part 10 and then are Bent and project outwardlyyas at 11, these outwardly-prov p a v jecting portions preferably being in'clined,'as shown, soils to lead away from the plane of the tool-holder. handles 7 can freely rotate without coming in contact with the lever 1 when in an inclined position, this heing'indicated in Fig. 1.
