CLAW FOR HAIVIIVIERS.

GPEUFIGATION forming part of Letters Patent No. 661,717, dated November 13, 1900.

Application filed August 17.1900. Serial No. 27,180. CNO model.)

To all wwnt t may concern:

Be it known that l, FRANKLIN I-IAwEs, of Boston, in the countyT of Suffolkand State of Massachusetis,have invented certain new and useful Improvements in Claws for Hammers, ot' which the following is a specification.

This invention has for its object to provide an improved adjustable claw i'or hammers; and it consists in the novel features of construction and arrangement of parts hereinafter described and claimed.

Reference-is to be had tothe accompanying sheet of drawings, forminga part of this application, and to the figures of reference marked thereon, the same reference characters designating the same parts or features wherever they occur.

Of the drawings, Figure 1 represents in side elevation and partly in section an adjustable claw constructed in accordance with my invention and mounted in place on a hammer, the ligure also showing in dotted lines one of the adj usted positionsot the claw. Fig. 2 is a detail sectional View of the same, a portion of the claw being broken away to show the relative position of parts, the pins in Fig. 2 being shown released in order to swing the claw while the detents in Fig. l are closed. Fig. 3 representsa cross-sectional view on the line 3 3 of Fig. l. Figl 4 represents a detail view of the claw. Fig. 5 represents in front 'elevation the spindle and its connected parts.

Referring to the drawings, l represents the handle of a hammer 7, that has the usual apertured hub 2 for the reception of a reduced portion 3 ofthe handle. The hammer has the customary driving-head 4.

2O represents my improved claw. This, as shown, is cored out, as at 2l, the open end of the core being conntersnnk, as at 22. The hub of the hammer opposite the end 4 is cored out, as at 30. Midway the ends of this core the walls of the recess are formed with screwthreads 3l. The claw 2O is formed with a reduced hub 23, arranged to fit loosely in the core 30.

4() represents a spindle formed on its outer end with screw-threads 41. The inner end of the spindle is enlarged and provided with screw-threads 42. The outerend ofthe spindle is cored, as at 43, to receive a spring 44.

45 represents a pin arranged in an aperture in the central part of the spindle 40, the spring bearing at one end upon the lower wall of the recess 43 and at its upper-end against the head of the spindle. The inner end of the screwthread enlargement 42 is centrally cored, as at 36.

46 represents a collar secured to the inner end of the pin 45 and formed with a central hub 47, arranged in the recess 36. The collar 46 is further provided with two pegs 4S 48,

.arranged to slide in complemental pairs of holes 49 49,'forn1ed in the adjacent walls ot' the core 2l and the spindle 40, said holes being continued through the screw-threaded enlargement 42. The pin 45 is normally held outward, or in the position shown in Fig. l, by the spring 44. Upon'depression of the pin 45 against the spring the collar 46 will be moved inward, removing the pegs 48 from the position shown in Fig. l, where the parts are locked, to the position shown in Fig. 2, where the pegs are withdrawn from the inner ends of their recesses 49, so that the inner ends of the pegs are in the screw-threaded enlargement 42, thereby leaving the claw 43 free to be-rotated about the spindle 40. The parts being constructed as described and shown,

the spindle, with its pin, (see Fig. 5,) is inserted in the core 2l, the screw-threads 42 engaging the screw-threads 3l, thus irmly locking the spindle to the hub of the hammer.

70 represents an internally-threadedv nut whose screw-threads are arranged to engage the screw-threads 4l on the outer end of the spindle, the nut. being of a size to firmly engage the walls ofthe coun tersnnk portion 22, the lower end of the nut engaging the lower Wall of the countersunk hole. The screwthreads 3l and 42 lock the spindle to the hub,

l ject.

The claw can then be rotated about the spin dle to the desired position, and the pegs can then be moved to engage the 'holes 49 and retain the claw in the desired adjusted position.

While I have shown four holes, and those so arranged that the claw may be adjusted to four different positions, I do not wish to be understood as limiting my invention to that degree of adjustment, since the same means could be employed for adjustments 'of varying degrees by varying the position of the holes.

By my invention the claw of the hammer can be adjusted to any position in order to readily engage the head of a nail or tack or other object. This is of great advantage, since in many situations it is impossible or difficult to engage the claw of the ordinary hammer with the head of a nail or other ob- By my invention'the claw can be readily adjusted to a position where the engagement can be readily effected. Further, the claw and hub and their associated parts are provided with such substantial bearing` engagements that the parts are united together with strength su fcient to stand the dilicerent strains to which the claw is subjected.

While I have shown and described my invention in connection with a hammer, I do not wish to be understood as limiting the application of my invention to that particular implement, as it is designed and intended for use in connection not only with hammers,

'but also hatchets, axes, and, in general, with the various tools and implements wherein claws are or may be employed.

The collar 46 andthe pegs 48 thereon are hereinafter referred to as a locking device and the pin as an operating memberA `which enables the locking device to be ma- The said locking device posinipulated.

tively secures the claw in different positions I to which it may be adjusted, and its location within the hob makesit inaccessible to dust and dirt, the projectingoperatingmember 45 enabling it to be readily manipulated.

Having thus explained the nature of my invention and described a way of constructing and using the same, though without attempting to settorth all of the forms in which it `maybe made or all the modes of its use, what I claim, and desire to secure by Letters Patent, is-r l. An improved implement, comprising a hub, a claw, and an adjustable spindle-and-- socket connection between the claw and hub, whereby'the claw may be adjusted to varying positions, and a locking device whereby the claw may be positively secured in different positions to which it may be adjusted.

2. An improved implement, comprising a hub, a socket formed therein, a spindle secured in said socket, a claw rotatably mounted on said spindle, a locking device within the socket whereby the claw may be locked in different positions 'upon' the spindle, and an operating member projecting from vthe socket whereby the locking device may be manipulated.

3. An improved implement, comprising a hub, a socket formed therein, a spindle secured in said socket, a claw loosely mounted on said spindle but maintained in operative relation thereto, a pin arranged in said spindle and carrying on its inner end a collar, means upon said collar for vengagement with said claw, the parts being so arranged that by the movementof said pin the claw will be released for adjustment,and thereafter locked in adjusted position.

In testimouywhereof I have affixed mjy signature in presence of two witnesses.

FRANKLIN. HAWES.
