IMPROVEMENT IN IIAMMERS.

To ALLV PERSONS To WHOM THESE PRESENTS MAY COME:

Y i Be it known that HORACE II. W. WRIGHT, of' South Boston, in the-county of Suffolk, and State of Massachusetts, have made a new and useful invention, having reference to Hammers and Screw-Drivers; and I do A hereby declare-.the same to be fully described in the following specification, and represented inthe accompanying drawings, of Whichv i j Y Figures 1 and 2 are longitudinal sections cfa hammer provided with my invention, such section being taken in' planes at right angles with each other.

In Such drawings, A denotes a hammer, of which a is'the handle, whose endis capped by e metallic socketed ferrulc, B, or, in `other words, a. socketedblock, arranged within and combined with a thimble, c. The socket c2, in the block 6, is prism'atic inform, it being rectangular in transverse section, and provided with a shoulder, e, arranged in it, in manner as represented in iig. 1. Ther'e is appliedto the block Z1, and so as to project 4tlironghami beyond lthe head'of the. thimble e", a springdatch, C, formed as shown in iig. 1.' Furthermore, there is within the'handle a'an extension, d, of the socket d, such being to receive the blade of a screw-driver, D.` -Thc said screw-driver, shown in edge view in Figure 4, and side view inlFigu-rc 3, is constructed with a prismatic 'shank',f, t'ot the socket d, such shank being larger in transverse Section than Athat oi" the blade of the screwdriver;4 that is, the shank at its junction with the blade terminates in a shoulder, g. The lenfrth of thev `shank corresponds with the distance between the shoulder e and the projection L of the latch O. The E handle a, inserted inthe fcrrulc or thimble B, 1s recessed to receive and iit closely to the block 11, the ferrule' being fixed firmly on the handle, 'and fastened thereto by screws it, (see fig. 2.) v With the handle and its'socleted ferrule, springdatch, and screw-driver, made as speciiied, the Screw# driver be fixed. `either en d foremost in the socket, the same being So that the -blade may either extend from Vthe fel-rule, or be reversed, and be inserted inr the socket d of the handle.

When a screw-driver is thus oombinyedwith a hammer, th head oi' the hammer, when grasped in the hand,4 will aord a stroug'leveragc for bringing the screwdriver into action upon and so as to revolve a. screw, whether' to remove it from or to drive it into an article. i

. .Having'thus described my lcombined 'hammer :ind screw-driver, what I claim therein is asfollows-z v 51' claim a reversiblescrew-driver, with shoulders, secured by a. spring, in, asocket, in the end of a. hammer- 1 handle, ,con'structedand arranged Substantially as described.
