Referring now to the form of my invention illustrated by the drawings, I will first describe the structure of my D-handle and then the method of securing the-parts 'together. i

Referring particularly to Figs. 1 and 7, I have showna D-handle which is a combination of wood and metal and provides a simple, durable and attractive handle particularly adapted for rough, hard usuage.

The metal part of the handle is in the form of a casing which is made up of two similar hollow, tubular portions or arms 1 pressed from sheet metal. The metal part is shown as Y-shaped and the two sections are secured together at the lower end for a portion of their length by welding the inwardly bent flange portions 2 (Figs. 2 and 10) of one tubular portion 1 with the cooperating flange portions of the other portion 1. The flanges 3-3 of each arm 1 are bent to meet at the inner face of the arm (Fig. 2) where they may be welded together to provide a substantially D-shaped crosssection. A reinforcing strip 4 may be welded to the inner faces of the flanges 3-3, if necessary, to prevent them from pulling apart.

The free ends of each arm 1 are rounded into cup-like portions to provide opposed grip-receiving sockets 5 between which the grip-piece 6 is held by a rivet 7 passing through the sockets 5 and center of the grippiece 6. The rivet 7 is headed at both ends into countersunk portions 8, thereby to hold the metal arms 1 against the ends of the grip-piece 6. The upper ends of the flanges 3-3 are bent inwardly at right angles to provide V-shaped means 9 at one side of each of the grip-receiving sockets and the inwardly turned portions are again bent to rest against the inner sides of the front face of the arms where they are welded to strengthen the V-shaped portion. This V-shaped portion presents flat surfaces which are located slightly inside of a circle, the diameter of the end 10 of the grip-piece 6 (Fig. 8), so that when the ends 10 of the grip-piece are forced into the sockets 5 the wood is compressed, as clearly shown in Fig. 8. By thus flattening the ends of the grippiece 6, I provide a locking means which prevents turning of the grip-piece 6.

The wooden stale or stem 11 of the shovel or other implement is first prepared for receiving the metal part of the handle by turning down the end to provide a shoulder 12 against which the edges 13 of the arms 1 abut. Then the turned down portion is preferably divided by a saw-cut 14, one portion of which is narrow to receive the welded flange portions 2 and the remainder of which is slightly wider (Fig. at) to receive the flanges 33 and reinforcing strip 4, as shown in Fig. 5.

When the handle is completely assembled, the wooden arms of the stem are .teler scoped into the metal arms of the casing whereby the casing forms a connection between the wooden grip-piece 6 and the stem.

Any suitable methodmay be employed to fit the wooden arms 15 of the stem 11 into the metal arms 1. For instance, I may employ substantially the same method as illustrated and described in the United States Letters Patent N 0. 1,477,742, issued to Thomas W. YVright December 18, 1923. However, I have invented a novel method which I have illustrated in Figs. 3 through 7, and which I will now describe.

Instead-of pro-forming the metal part of the handle to the shape of a Y and then forcing the arms 15 of the stem into the Y, I prefer to leave the metal casing straight, so that the arms 1 are parallel and then insert the split portion of the stem into the casing, as shown in Fig. 5. Thereafter I employ suitably shaped die means v(not shown) whereby the metal arms 2, together.

with the wooden arms 15, are formed into substantially the shape shown in Fig. 6. Then the grip-piece is inserted in position and the upper ends of the Y are forced toward each other, thereby forcing the sockets 5 over the ends 10 of the grip-piece 6. The rivet 7 is then secured in place and the D-handle is completed and ready for use.

The exact point at which the ends of the wooden arms 15 terminate is not particularly important, but I prefer to have them terminate beyond the curved portions 16, so that the tubular arms will retain their proper shape as to cross-section during the forming operations.

My method of assembly is particularly simple and I have found that it is unnecessary to steam the. stale before spreading the arms. This is particularly advantageous because the wood has a tendency to shrink after steaming and, therefore, my method of bending the arms 15, while they are dry, eliminates the possibility of looseness between the arms 2 and the arms 15. Furthermore, I have found that the welded flange portions 2-prevent splitting of the woodat the end of the saw-cut 14 and eliminates the necessity for the usual rivet at this point.

My handle is simple and durable and the method of assembly reduces the number of operations to a minimum, while at the same time providing a handle which is superior in quality and construction to any handle of this general type now known to me. 7

'While I have illustrated and described a preferred construction ofmy device and a preferred method of assembly, I do not wish to be limited thereby, because the scope of my invention will be best understood by the following claims.

I claim:

1. A method of producing a D-handle which comprises forming a metal part with two separate parallel hollow arms, dividing a portion of one end of a stem longitudinally to provide a pair of parallel wooden arms, inserting the wooden arms of the stem into the hollow metal arms and then bending the metal arms and the wooden arms together into a substantially Y-shaped formation- 2.
