Specification of Letters Patent.
Patented Apr. 13, 13115.
To all whom it may concern:
Be it known that I, lVrLLIAM R. HUNTER. citizen of the United States, residing at- Cleveland, in the county-of Cuyahoga and State of Ohio, have invented new and useful Improvements in Plasterers Tools, of which the following is a specification.
The objects of the invention are to increase the durability of lasterers tools without materially increasing the weight thereof; and to render the tools capable of being packed into relatively small work bags while being carried from place to place. T he above and other objects will appear and be better understood from the following description taken in connection with the accompanying drawings in which:
Figure 1 is a plan view of a plasterers hawk constructed in accordance with my invention; Fig. 2 is a bottom plan of the same; Fig. 3 is a fragmentary perspective of the frame; Fig. 4 is a similar view of the plate; Fig. 5 is a plan view of a darby constructed in accordance with my invention; Fig. 6 is a vertical longitudinal sectional view of the same; Fig. 7 is a detail vertical sectional view of a fragment of the holding plate shown in the hawk or darby construction and further showing the handle in section and connected thereto.
Referring to Figs. 1 to 4 inclusive the holding plate a in the embodiment shown is made up of an aluminum frame 5 and a wooden plate 6. A mortise 7 is formed in the lower face of the frame 5 and receives the mortised portion 8 of the plate 6. The upper surface of the plate 6 is plain and coincident with the upper surface of the frame 6 whereby the upper surface of the plate as a whole will present no obstructions to impede the progress of a plasters applying tool moving thereover.
A plurality of inwardly extending ribs 9 are formed with the frame 5 and are received by correspondingly shaped notches 10 in the plate 6. The ribs 9 have counterbored openings to receive screws 11 or their equivalents which pass through the bottom of the mortised portion 8 of the plate and serves to secure the plate as shown. The corner portions 1 of the frame are oblique with respect to the sides of the frame; the corner portions of the plate are correspondingly shaped as shown at 13. The corner portions of the frame have counter-bored openings to receive fastening screws 14 or their equivalents which pass through the plate 6.
With this construction it will be seen that the plate may be tapped as usual in order to dislodge the plaster therefrom without danger of indenting or otherwise roughening the sides and forming obstructions in the upper face of the hawk. It will be seen that the provision of the frame prevents the plate from warping.
The plate 6 is strengthened by convexing the lower face thereof as shown at 15 and the central portion of the convex surface has a metallic plate 16 secured thereto, the plate 16 having an interiorly threaded socket 18 which is received by a bored handle 19 having a screw 20 to be screwed into the socket 18. In the form illustrated in Figs. 5 and 6 the holding plate 6 of the darby is made up of two sections 0 and d. The holding plate of each section includes an aluminum frame 21 and a plate 22 the latter having a mortise 23 receiving the mortised portion 24 of the frame 21. The section cl at one end is under-cut as at 25, this under-cut portion receiving a mortised end portion 26 of the section 0. The under-cut portion has dowels 27 which pass through openings in the mortised portion 26 and winged nuts are screwed on the dowels whereby the sections 0 and cl are detachably secured together as shown.
The sections 0 and d are provided on their upper faces with plates 29 and which have interiorly threaded sockets 31. The handles 32 are bored to receive the sockets 31 and have screws 33 which screw into the sockets 31. With this construction it will be seen that the sections 0 and (Z may be readily detaohed and be packed into a comparatively small compass when not in use. So also may the handles of the said sections 0 and (Z and also of the hawk be detached from the plates when it is desired to pack the tools as before described.
Although I have shown and described one form of the device it is to be understood that T am not to be limited to such showing and description since various changes may be made within the scope of the claim without departing from the spirit of the invention.
lVhat is claimed as new is:
A plasterers hawk comprising asubstantially rectangular plate the plate being formed of wood, said plate being formed llTtl Copies of this patent may be obtained for contact With the beveled corners of said tenon, and V-shaped projections formed integrally upon the inner edges of said setting and arranged to fit into said V shaped notches.
In testimony whereof I aflix my signature in presence of two Witnesses.
