To all whom it may concern:

Be it known that 1, ROBERT A. Monr- GOMERY, a subject of the King of Great Britain, and a resident of Indiana, in the county of Indiana-and State of Pennsylvania, have invented a new 'and Improved Wrench, of which the following is a full, clear, and exact description.

lhe invention is an improvement in internal wrenches, more especially for radiator valves, and has in View a tool presenting a number of such wrenches of varying size, each wrench being stepped from the adjoining wrench, and the several Wrenches decreasing in size point of the tool, the outer edges of the wrenches preferably, though not necessarily,

presenting cutting edges, adap ing the tool 1 i to be also used as reanier.

toward the inner end or portion of the bodyof the tool a either integrally or separately attached and consists of a square or other angular wrenchengaging portion 7 adjacent to the tool body, and a reduced extremity 8 having in its end a socket wrench 9. At diametrically opposite points the wrench-engaging portion 7 of the shank is provided with threaded recesses 10, which serve to attach handles, as indicated in dotted outline in Fig. l, in operating thetool, or the handles may be dispensed with and a wrench applied directly to the angular portion Z in using the tool as either a rcanier or wre .ch.

A disk 10 the junction of the shank end tool body reinforces the connection hetwee e and rests on "I he LG which it is rigidly join J the blades together and Reference is to he had to the accompanyf Pffivtnil the 5; mg drawings a part or this specii V ea fication, in which similar the views.

l is a side view of central vertical section; Fig. :2 is an inner end view of the tool; and Fig. is a cross section of the tool on the line 3--3 oi? Fig i, on an enlarged scale.

The body of the tool is composed number of blades 5 radiating "5mm a men central stem to which they are grally throughout their length,

of a

commice- The shoulders formed at the edges of i the several blades, prererably incline inwardly toward the point of the tool in order that; a bur may be easily out from the end of a pi e in inserting the next larger portion of t e reamer. "At the inner and enlarged characters oi? reference indicate corresponding parts i". K

the tool partly 1 formed or otherwise rigidly connected blade has a stepped outer cutting tour of these blades g being shown arranged ninety degrees apart, s

a one too-i is especially usefu hich work, as a r o the tail-piece oi sizes the blades or .e internal projections prov .inec'tion with these pipe fittings, when the fitting screwed on or oil the radiator con- The tool as a manner is especially or'cutting the burs from. the ends one size pipes, after which the next larger portion of the tool is easil inserted.

to .ing thus described my invention,

as new and desire to'secure by Letters ens tool comprising a central stern haw blades radiating therefrom, the blades having stepped outer cutting edges forming a number of wrenches successively increasin v size from the outer end oi": the tool tower the inner end or shank of the tool, with each 1-31'3h. of approximately uniform diameter throughout its length.

A tool wrnprising a central stem having blades radiating therefrom and with the stem substantially their full len Lh, the blades nccessively decreasing in Width from the inner to the outer end of the tool a succession of internal. wrenches, said the inner end of the blades to provide a shank havin a reinforcing disk rigid and with the inner ends of the 5. tool having blades radiating from a stein hein" extended he 'ond shank is common longitudinal axis, the blades tapering in cross-section, with the thickest por-.

tion of each blade arranged adjacent to said axis, said blades having stepped outer edges forming a succession of internal wrenches successively increasing in size from the outer end of the tool inwardly.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ROBERT A. MONTGOMERY.
