SHOVEL HANDLE William Fenton, deceased, late of Dayton, Ohio, by Elizabeth P. Fenton, executrix, Dayton, Ohio, assignor to The Fenton Foundry Supply Company, Dayton, Ohio, a corporation of Ohio Application October 20, 194i, Serial No. 780,860

This invention relates to tool handles, and more particularly to a detachable grip for the handles of molders shovels or the like which are likely to be inverted for use as tampers.

The present handle grip is particularly intended for use on molders shovels, in which case it is common practice for the user to invert the shovel,

using the handle portion for a tamping tool to tamp the sand solidly around the pattern. It has, however, been found advantageous and has been accepted in other fields, since the resilient handle portion absorbs to a considerable extent the shock normally transferred to the users hand.

The object of the invention is to improve upon such tool handles with respect to their efficiency, durability and simplicity by providing an easily assembled and cheaply produced two-part grip structure comprising a cast metal body anda rubber or rubber-like pad mounted on the body in interlocking relation therewith.

Another object of the invention is to obtain an improved connection between the grip body and pad thereon, facilitating assembly of the parts into a sturdy, separation resistant unit, but permitting easy replacement of the pad when worn.

A further object of the invention is to make available a grip which may be applied to new and existing tool handles as a means of reducing shock in the use of the tool and as a tamping implement supplementing the normal use of the tool.

In carrying out these objects, there has been provided a tool handle grip comprising a unitary cast metal body forming a shank for attachment to the tool handle, and further forming spaced arms extending from the shank and terminating in a cross bar lying at right angles to the longitudinal axis of the shank, the handle grip additionally comprising a rubber peen superimposed upon the cross bar, the cross bar and peen being formed with interengaging tongue and groove portions interlocked by reasonof complementary angular formations.

A further object of the invention is to provide an assembly of the character described possessing the advantageous structural features, the inherent meritorious characteristics and the mode of use herein described, or their equivalents.

With the above primary and other incidental objects in view as will more fully appear in the specification, the invention intended to be protected by Letters Patent consists of the features of construction, the parts and combinations thereof, and the mode of operation as hereinafter 2 Claims. (01. 29457) described or illustrated in the accompanying drawings, or their equivalents. V In the accompanying drawing, wherein is shown the preferred but obviously not the only embodiment of the invention,

I Fig. 1 is a view in perspective of a molders shovel equipped with a grip according to the present invention;

Fig. 2 is'a view in perspective of the grip portion of the handle of Fig. 1;

Fig. 3 is a view in side elevation of the body of the tool handle grip, the rubber tamping peen being omitted; and

Fig. 4 is a view in perspective of the rubber tamping peen forming a part of the handle grip. Like parts are indicated by similar characters of reference throughout the several views.

Referring to the drawings, there is illustrated in Fig. 1 a shovel having a handle grip constructed and arranged in accordance with the present invention. The shovel may be one of general utility, but in the illustrated embodiment is particularly adapted for use by foundry molding workers, one end of the device being a conventional shovel portion and the other or grip end being adapted for tamping in and around patterns, the tool being inverted when used as a tamper.

The device comprises a shovel portion I 0 secured to one end of an elongated handle II. The opposite end of the handle is reduced in diameter for a telescopic fit with a detachable grip l2.

,The'handle gri I2 is of unitary cast metal construction, being preferably made of aluminum for lightness of weight. The grip comprises a shank portion l 3, made hollow to receive the reduced outer end of handle H. An opening I 4' in the shank [3 (see Fig. 2) is provided for the passage therethrough of a screw l5 or other connection means extending into the handle H. Extending upward from the shank 13 are spaced arms- 14 terminating at their outer ends in a cross bar I5 interconnecting the arms and lying at right angles to the longitudinal axis of the shank I3. The arms !4 and cross bar I5 define a substantially D-shaped enclosure.

The sides and under surface of the cross bar l5 are curved while the outer surface of the bar is flat. Within the fiat outer surface of the cross bar l5, and extending through the opposite ends thereof, is a longitudinal groove l6 (Fig. 3). The bottom of groove l6'1ies in a plane parallel to the fiat outer surface of cross bar I5, while the side walls of the groove are inclined in planes convergent at a point above the cross bar I5, thereby forming reentrant angles l6 intermediate the side walls and bottom of the groove.

Superimposed upon the fiat outer surface of cross bar l5, and in a position overlying groove it, is a peen i! made of a, relatively soft rubber or rubberlike; material. The peen is coincident in length with the length of cross bar ['5 and is formed on its underside with a longitudinal tongue 18 received in groove l6. The tongue l8 has a broad, fiat base from which the side walls taper inward and upward, the resultant shape of the tongue being complementary to the forma tion of groove [6, The peen I1 is mounted on the cross bar it by a longitudinal slidin motion of tongue 18 within groove It, and when so interiengaged the peen and cross bar are interlocked against accidental removal or dislodgment during tamping. To inhibit axial displacement ,of the peen upon the cross bar, a suitable cement or other adhesive may be applied to the contacting surfaces of the peen and closs bar prior to as: sembly. 1

That portion of the peen ll lyingoutside groove is is in registry With the outside edge of the topsurface of cross bar and the sides thereof are externally curved to form continuations of the curved under surface of bar I5. The curved side surfaces of the peen terminate in a blunt end surface is to give the peen a wedge-like shape effective in tamping. It will be understood that the grip portion l2 normally is used as a grip, with the rubber peen Il serving merely to complete the formation of the grip and to reduce the amount of shock imparted to the hand of the user. When itis desired to use the tool for terming, however, it is inverted and the grip 12 then becomes the working end of the tool, with the wedge shaped peen I! being applied to the sand or other material being tamped.

From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but, which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without, departing from the principle involved or sacrificing any of its advantages.

While in order to comply with the statute the invention has been described in language more or less specific as to structural features, it is to he understood that the invention is not limited a 4 shank and terminating in a, cross bar interconnecting said arms and lying at right angles to the longitudinal axis of the shank, said cross bar being formed with a curved under surface and a fiat outer surface, longitudinal groove in the flat outer surface of said cross bar and opening through the ends thereof, a resilient member mounted on the outer surface of said cross bar in overlying relation to said groove and having a longitudinal tongue received in said groove,

., faces of said member terminating at their upper Lil ends in a longitudinal flat area whereby said member has in cross'se ction a wedge-like shape useful in tamping upon inversion of the tool handle;

'2. A-grip for a tool handle, comprising a one piece cast metal portion forminga shank for at: tachment to the toolahandle and further forming spaced arms extending upwardly from the shank and terminating in a cross bar intercomnecting said arms and lying at right angles to the longitudinal axis of the shank, said cross bar being formed with a curved under surface and a flat outer surface, a longitudinal groove in the flat outer surface of said cross bar and opening through the ends thereof, a resilient member mounted on the outer surface of said cross bar in overlying relation to said groove and having a lcngitudinaltongue received in said groove, said groove andsaid tongue having complementary inclined side Walls constituting an interlock between said member and said cross bar when the tongue of said member is inserted in the longitudinal groove of the cross bar by a sliding motion at right angles to the longitudinal axis of the shank, and that portion of said member outside said groove being externally curved in conformity with the'curvedsurface of said cross bar, the curved surfaces of said member terminating at their upper ends in a longitudinal flat area whereby said memberhas in cross section a wedge-like shape useful in tamping upon inver-. sion of the tool handle.
