A. A. WIRT.

TANG MOUNTING FOR IMPLEMENTS.

C T l9 1- '1,382,155 Patented June 21, 1921.

v Cute Luv UNITED STATES PATENT OFFICE.

ASA A. WIRT, OF OMAHA, NEBRASKA.

TANG-MOUNTING non IMPLEMENTS.-

To all whom it may concern:

zen of the United States, residing at ()maha,

in the county of Douglas and State Of Nebraska, have invented certain new and useful Improvements in Tang-Mountings for Implements, of which the following is a specification.

This invention relates to a tang mounting, in handles, for implements, and has for its principal object to provide an improvement in the tang mounting for implements shown and described in an application for U. S. latent filed by applicant May 14th, 1920, Serial N 0. 881,300, the present improvement consisting, in part, of such a construction that the ferrule will be disconnected from the tang to permit the ferrule to be pressed against the tapered end of the handle, this feature being important in some instances on account of shrinkage of the handle. Other novel features of the invention will be mentioned hereinafter.

The present embodiment of the invention is illustrated in a drawing wherein, Figure 1 is a side view, partly in section, showing the mounting of the tang in a handle, parts being broken away. Fig. 2 is an end view of the tang and ferrule.

Referring now particularly to the drawing, numeral 3 indicates a handle provided with a recess a opening on its front end and having a tapered terminal 5. Numeral 6 indicates a ferrule having an outwardly di vex-gent recess 7 formed in one of its ends for receiving the tapered terminal of the handle, its opposite end being provided with a recess 8 of uniform diameter opening on its aperture.

Numeral 9 indicates a tang, and it will be understood that this member may be the shank or tang of any tool or implement to be mounted in the handle, said tang being provided with a boss or collar 10 of such proportion that it will fit loosely in the recess 8 when the tang is inserted in the ferrule and recess 4: of the handle.

Numeral l1 indicates a spiral spring adapted to be inserted in the recess 8 and to be mounted loosely upon the tang inwardly of the collar 10; and at 12, rearwardly of the ferrule, is a pin or rivet adapted to traverse the apertures a and b, respectively, of the tang and handle.

Specification of Letters Patent. P t t June 21, 2 Application filed April 11, 1921.

Serial No. 460,397.

It will be noted that the parts may be readily and conveniently assembled. After the ferrule has been placed upon the tapered part of the handle and the spring has been placed in the recess 8, the tang is pressed.

inwardly against the force of the spring until 1ts aperture a is in line with the aperture {5 of the handle, and the pin or keeper 12 is then inserted in said apertures, the spring 11 being of such proportion that it will be compressed and will abut upon the boss 10 and inner wall of the recess 8.

According to the construction described it will be appreciated that the tang will not become loose relative to the handle or ferrule, regardless of shrinkage of the handle or rust of the ferrule since the pin 12 does not traverse the ferrule, and said ferrule will be constantly pressed toward the handle; and stresses directed to the collar 10 of the tang, by the spring, will be supported by the inner wall of the recess 8, tending to prevent vibration of the tang. t is considered that the provision of a tapered endportion for the handle is an advantage, in the present instance, since it facilitates pressure of the ferrule against this part.

I claim as my invention:

In a tang mounting for implements, a handle having a tapered part and a recess, a ferrule provided at one of its ends to open on its aperture with a recess having an in wardly convergent wall to lie outwardly of the recess and tapered part of the handle and provided to open on its opposite end and its aperture with a second recess, a tang having an aperture and a boss and disposed in the aperture of the ferrule and re cess of the handle, a pin adjacent to the ferrule traversing the handle and aperture of the tang, and a resilient member in the second recess of the ferrule engaging the boss and tending to move the ferrule for causing engagement of the convergent wall of its first named recess with the tapered part of the handle.

In testimony whereof, I have affixed my signature in presence of two witnesses.
