Application filed -July 3.1,

expensive construction in which the body portion may be formcd'of asingle piece of sheet metal and the handle deta chably connected therewith in suchamanner that the handle'andbody maybe readily removed for convenience in shipping, handling and storing, and also-readily, quickly and easily connected with each other, and-"when connected will be firmly and inimovably united;

and

Further to provide a device oft-his kind in which all of the parts are permanently connected either to the handle. member or the bodymember so that the smaller connecting members cannotbecome lost or misplaced in shipping or storing.

My invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 1 shows a perspective view of my improved plasterers hawk with the handle and the body portion assembled.

Figure 2 shows a perspective view of the socket holding plate detached.

Figure 3 shows a perspective view of the socket for clamping the plate and handle together; and

Figure at shows a vertical, central, sectional view of the complete device assembled.

Referring to the accompanying drawings, I have used the reference numeral to in dicate the body portion or plate of my improved plasterers hawk, which is preferably made of a single piece of sheet metal such as aluminum of proper size and thickness.

For comiecting the body portion to the handle, I have provided a socket holding plate indicated generally by the numeral 11. This plate is also preferably formed of a piece of sheet metal, and its central portlon is formed with a circular depression at 12, and in the center of the circular depression is a rectangular opening 13. Around the 1922. Serial "NOI 574,141.

e'dgesofthe plate are left openings let. This plate is permanently connected to the body portion 10 of theh'awk by rivets 15, the ends of the rivets being ground flush-with the upper face of the hawk body.

For connecting the hahtllewiththe plate Iprovide asocketmembercomprising a base "16 with a rectangular raised. portion 17 formed on one side of 'it,and'a'cylindrical socket member--19 at the center of the portion 17. The socket member isiinternally screw threaded. The thickness of the'ba'se 16 corresponds with the depth of the de 'pression 12 in'the plate 11, and the part 17 'isof such size as to freelyenter-and fit into the rectangular opening 13. This memberis, of course, placed in "positionwithin the depression of the socket holding. plate before the latter is riveted-to the hawk body.

The handle is preferably fermed-of abody portion 20 which maybe made of'w0od,"'and has'a circular opening extending th-roughit to receive the bolt/21. The head ofthe bolt 22 reinforces and protects the outer end of the wooden handle and the bolt is prevented from rotation within the wooden handle by means of the teeth 23 formed on the bolt near its head, which teeth are forced into the handle.

At the opposite end of the handle there is an enlarged cylindrical opening at 24: designed to receive the cylindrical socket 18. The screw threaded end of the bolt is designed to enter the screw threaded interior of the socket 18.

In assembling the device the socket, which may be cast complete in one piece, is placed loosely within the socket holding plate, and the latter is riveted to the hawk body. This may be accomplished readily and quickly and with slight expense, because it is not necessary that the socket member accurately fit in the socket holding plate. It is only necessary that the heads of the rivets which project through the socket holding plate be ground off smooth with the surface of the plate.

The handle is cheap and inexpensive because it consists only of the wood handle and the bolt. However, the bolt is permanently fixed to the handle and hence there are only two parts to the device, to wit: the body portion and the handle portion. The handle may be readily and easily removed for shipping, packing or storing.

In order to assemble the device, it is only necessary to place the screw threaded end of the bolt into the screw threaded socket and then turn the handle until the end of the handle engages the socket holding plate, then by tightening the handle the edges of the socket enter the plate surrounding the screw threaded opening 13 and firmly clamps the base of the socket holding plate and the adjacent end of the handle. In this manner, any lost motion that there might be between the socket andthe socket holding plate is taken up and the parts are firmly united, but the handle may be removed without the use of tools, by simply unscrewing it.

I claim as my invention:

1. An improved plasterers hawk comprising a body portion having a fiat face to receive plaster, a socket holding plate fixed to the under surface or the body and formed with a depression at its central portion having an angular opening therein, a socket device having a base to be received in the said depression and an angular projection to be received in said angular opening and a cylindrical internally screw threaded socket projecting beyond said opening, a handle inember comprising a handle proper having a screw threaded rod therein and an annular recess formed in the handle surrounding the screw threaded portion of the bolt and designed to receive the said cylindrical socket, said parts beine' so shaped and proportioned that as the bolt is screwed into the socket, the

handle will engage the socket holding plate and cause the socket holding plate to be L vice having a base to be received in the said depression and an angular projection to be received in said angular opening and a cylindrical internally screw threaded socket projecting beyond said opening, a handle member comprising a handle proper having a screw threaded rod therein and an annular recess formed in the handle surrounding the screw threaded portionof the bolt and designed to receive the said cylindrical socket, said parts being so shaped and proportioned that as the bolt is screwed into the socket, the handle will engage the socket holding plate and cause the socket holding plate to be clamped between the base of the socket and the adjacent end of the handle, and means for fixing the bolt against movement relative to the handle.
