CHISEL'HANDLE.

lljatented Dec. i, 1914.

Application filed June 16, 1514:. Serial Nm 845,468.

To all whom may conccrn Be it known that L'LUDVIG T. LANGAGER,

'ful lmprovements in Chisel-Handles; and

I do hereby declare .the following to be e full, clear, and exact description of the in-.

vention, such as will enable others skilled in the art to `which it appertains to make and use the same.

This inventlon relates to a chisel handle.

An object of the'invention is to provide a device of this Character which may be. at tached' to various tools which when in use are struck by a hannner tor the like.

A furt-her object of the invention is to provide a device that the jar incident to the striking of the tool will be takencare of in the handle and not transmitted to the hand.

vWith these and other objects in view, such aswill appear as the description progresses, my invention comprises the combination and arrangement of parts as herein set forth' and subsequently claiined.

Referring to the d1.'a\\'in.g: Figure 1 is a Fig. 2 is a View showing' the device in one position which it Will assume When .the chisel leans in one direction duringthe striking of the same. lflg. 8 is ay plan view of the devlce.

Fig. 4 is a longitudinal section. Fig. 5 is a 'screw t.

section on line 55 of Fig. 1. Fig. G is a section on line 6-6 of Fig. 1.

Referring to the drawing by reference characters wherein like parts are indicated bylike characters throughout the several Views,-1ny device comprises a rod 1 circular in cross section for a part of its length, as at 1', and squared in cross section for the remainder of its length, as at 1, and having a gripping member 2 securcd to one end' thereof by means of a collar 3 and a set The opposite end of the rod l is bifurcated, as at 5, forininz circular cars 6 having-holes 7 therein. Pivoted between these ears is a triangular shaped member 8 having upwardly and downwardly extend- ,ing wings 9 and a forwardly extending cylindrical shank 10, which shank is threaded on the end, as at 11. .The rear faces of the Wings 9 are fi'at, as at 12, and these faces are normally held 'in a Vertical 'position by a. collar 13 sli'dably mounted on the squared portion 1 of the rod 1. '011 one end of this collar are outwardly projecting portions li of such width as tovslide between the 'ears G. A coil spring 15 encircling vthe 'rod l bea rs against the other end of ythis collar 13 and against an adjustable collar 16 held in place on the rod 1 by a set screw 17. The threaded end 11 of the member 8 is adapted to be screwed into a threaded hole in a cold chisel or any similar tool;

In operation When the chisel is struok by a. sledge or other hammer assuming that-'the said chisel is attached to the device and held in position by the gripping portion 2 of the device and the blow causes the chisel to be throwncfrom the Vertical, the jar incident to'said blow `Will be taken "up by the spring 15 because of the'fact that the member 8 moves about its pivot and one of'the Wings 12 presses against Aone projection 14 of the collar 13 so as to compress thespring 15. It is of course to be -understood that if the upper end of the chisel leans toward the gripping member 2 the spring will be compressed by the upper Wing 12, While if it leans in the opposite direction the spring Will be compressed by the Wing 12. Assuming that the handlel is held in a' horizontal position and the chisel is driven downwardly ina Vertical position the handle Will move about its pivot and thus' the jar Will be taken care of.

ltmay be thus seen that l have provided a handle for attaohment to a chisel or'the like which chisel is to be struck by the hammer, the said handle being of such construction that all jar incident to the striking` will be taken care of.

Thile I hare described a particular constr'uctioin I do not Wish to be limited to that construction, foi` it is obvious that numerous changes may be made within the kcope of the invention as defined by the claims.

lVhat is claimed is z- '1 handle comprisingr a rod cylindrical in cross section for a part of its length and squared in cross section for the remainder of its length, a grip member 'dctachably secured to one end of the. rod. spaced cars formed on the other end of the rod, a triangular member mounted between said ears having upwardly project-mg Wings and an outwardly extending` threadcd shank, a squared collar slidably mounted on the rod and pressing against the said \\'ings. a coil spring. ci'lcircling the rod and `n'cssing against the collar at one of its ends, an adllO 2, A handle comprising a rod, a triangu- 121.1' member pivoted to the end'hereof and having an outwardly extending threaded shank, a coilar mounted on the rod and bearing against said triangular member to maintain the shank in alinement with the l'od 'an resiiient means for maintaining the coliar in operative position.

3. A hndle comprising a rod, a member ture, in the presence of two witnesses.
