IMPROVEMENT IN WRENCHES.

Speciiication forming part ot' Letters Patent No. 164,567, dated June 22, 1875 application filed January 16, 1875. i

To all whom vit may concern:

Be it known that I, JAMES NORTON, of Middlebury, in the county ot' Addison and State of Vermont, have invented certain new and useful .Improvements in a Combined Wrench and Oiler; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accom- -panying drawings, and to the letters ot reference marked thereon, which form part of this specification.

The nature of my invention consists in` providing a wrench with an oilereservoir in the handle, or forming the handle hollow to constitute an oil-reservoir, which is so constructed that it can be securely closed against leakage, yet be easily and quickly opened by the operator. It also consists in forming a wrench ot' removable pieces, so that those parts that are liable to be worn and broken may be easily and quickly removed from the handle and stem and replaced by new parts, thus making a wrench that can be easily and cheaply repaired by the owner.

In the accompanying drawin g, Figure l is a side View, partly in section, ot' a wrench embodying my invention. Fig. 2 is a cross-sec tion through the line .r m, Fig. 1.

A represents the handle of my wrench, formed at one end with the stem O. The handie is made hollow, so as to form an interior chamber, B, for the reception of oil. In the other end of the handle is inserted a screw, J, which is formed at its inner end with a valve, a, to close the entrance b'to the oilchamber. By slightly unscrewing the screw J the oil will ow around the valve a and'out at the side outlet d. E is the stationary jaw of thewrench, which is dovetailedl sidewise onto the end of the stem, as shown at h, and is fastened by a screw, D. rlhe stud G, through which the adjustingescrew H passes, is in like manner fastened to the stein() by a dovetail,

h1, and secured by a screw, D2. The movable jaw F, operated by the screw H, moves in dovetails h2 in the sides of the stem. By thus att-achin g the4 parts E F G to the stem by dovetails, they are easily removed in case of breakage or when worn, so as to be replaced by new ones.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination of the wrench-handle A with interior oil-chamber B, having passage b, the screw J, with valve a, and the outlet d, all substantially as and for the purposes herein set forth.

2. The stationary head E, provided with a T-shaped or dovetailed groove, fitting over the end of the stem, the two parts secured by means of a screw, I), substantially' as and for the purpose' set forth.

In testimony that I claim the foregoing as my own I aftix'my signature in presence of two witnesses.

JAMES NORTON.
