PLASTERERS HAWK.

Application led September 21, 1925. Serial No. 57,625.

My invention relates to tools and more particularly to a plasterers tool known as a hawk.

The primary object of my invention is t-o provide an improved plasterers hawk made in parts which may be assembled or disassembled readily so that they may be conveniently stored or packed for shipping and so that worn out or damaged parts may be replaced by new ones.

Another object is to provide a plasterers hawk of the character described which will be light, durable and relatively inexpensive.

Other objects and advantages will appear hereinafter and while I show herewith and will describe a preferred form of construction, I desire it to be understood that I do not limit my invention to such preferred form but that various changes and adaptations may be made therein without departing from the spirit of my invention as hereinafter claimed.

My invention is illustrated in the annexed drawings which form a part of this specification and in whichl Figure 1 is a plan view of my plasterers hawk with part of the receiving board broken away to disclose the frame thereof, the outlines of the missing part of the receiving board, the obscured part of the frame and the handle being shown in dotted lines.

Figure 2 is a sectional view of the plasterers hawk shown in Figure 1, the section being taken on line 2-2 of that figure.

Figure 3 is a fragmentary plan view of the central part of the frame slightly modilied.

Figure 4 is a side view of the frame shown in Figure 3, with a receiving board attached thereto and shown in section.

Figure 5 is a fragmentary sectional view of a plasterers hawk, with a slightly modilied frame part, the handle of which is omitted and its position shown in dotted lines.

Referring in detail to the drawings the plasterers hawk consists of a square piece -10 of comparatively thin board which serves as the receiving plate and which is secured to a light metal frame 11, preferably of aluminum, to which a wooden handle 12 is attached. The frame is .made in the general form of the letter H having two parallel bars 13, like angle iron in cross section, with a relatively wide and thin plate 14,

connecting them at their middle points, said plate preferably being made integral with said bars and rigidly holding them in spaced relation to each other.

Bosses 15, with screw threaded holes are formed at the ends and at intermediate points of parallel bars 13 to receive fastening screws 17 which extend through receiving p-late 10, the holes in the latter being countersunk so that the screw heads are seated well below the surface thereof as shown in Figure 2. A central boss 18 with an vaperture 19, adapted to receive the shank of a square headed bolt 20, is formed on the under side of plate 14, the upper side of which is provided with a recess 21 in which the bolt head iits so that the bolt can not turn in the boss.

The wooden handle 12 is provided with a recess 22 and an internally screw-threaded sleeve 23 in its upper end, the recess being adapted to receive boss 18 and the sleeve being adapted to engage the projecting end 24 of bolt 20. The sleeve is held from turning in the handle by a pin 25 driven through the handle and the lower end of the sleeve which is provided with holes to receive it.

The modified form of hawk shown in Figures 3 and 4 has the same receiving plate, frame and handle as that shown in Figures 1 and 2 but differs from the latter in plate 14 having a larger boss 26 and an elongated recess 27. Furthermore boss' 26 is provided with an aperture 28 in one side thereof, under plate 14, which communicates with recess 27, and a slot 29 which coincides with the middle line of recess 27 and aperture 28. Clearance is thus provided so that the head of bolt 20 may be slipped through aperture 28 into recess 27, slight grooves being cut in the bolt, just under its head, to provide further clearance.

The modiiication shown in Figure 5 differs from those described in that boss 18 is provided with a central slot 30 and a side slot 31 communicating therewith. Furthermore a screw-threaded pin 32, pivoted to boss 18 as at 33, so that it may. be swung sidewise in slot 30 and into slot 31, as shown in dotted lines, takes the place of bolt 20.

With the construction shown it is evident that my improved plasterers hawk is exceptionally light and durable and that worn out or damaged parts may be readliy replaced by new ones. lVhen the hawks are to be stored or shipped the handles may be ioo removed by unserewing them entirely from the frames, or, in the type shown in Figures 3 and 4, by unscrewing them just sufficiently so that the bolt head may be slipped out of recess 27 through aperture 28.

Having thus illustrated and described my invention, I claim:

A plasterers hawk comprising` a metal frame having two spaced parallel bars connected by a cross-plate in the general form of the letter H, a boss formed on the under side of said cross plate at its center, said cross-plate and boss having a recess and an aperture adapted t0 receive a bolt head, a bolt having its head seated in said boss so that its threaded end projects from the center thereof, a handle, an internally screw threaded sleeve Xed in the end of said handle adjacent said frame, said sleeve being adapted to engage said bolt to hold said handle detachably secured to said frame, and a Wooden receiving plate detachably fastened to the upper side of said frame.

JOHN TASEFF.
