JOHN MARTIN DAVIS, OF GREAT FALLS, MONTANA.
PLASTERERS'HAWK.
SPECIFICATION forming part of Letters Patent No. 534,741, dated February 26, 1895.
Application filed May 9, 1894. Serial No. 610,6 2 (No model.)
To aZZ whom, it may concern.-
Be it known that 1, JOHN MARTIN DAVIS, a citizen of the United States of America, residing at Great Falls, in the county of Cascade and State of Montana, have invented certain new and useful Improvements in Plasterers Hawks, of which the following is a specification, reference being had therein to the accompanying drawings.
Heretofore plasterers hawks have been constructed of a board having-a dovetail shaped mortise in the rear side extending v transversely of the grain or the fibers of the wood. A corresponding shaped cleat of wood is driven into this mortise to strengthen and prevent warping of the board, and a handle is permanently attached to the hawk usually by having a tenon at its end, which is fitted into a mortise in the cleat and the board. A hawk of this construction can only be made by a skilled mechanic andhaving the handles permanently attached is unhandy and makes a bulky package.
The purpose of this invention is to provide a hawkhavin g a detachable handle which can be readily removed and quickly attached to the board at will, and which when in place will be firm and rigid; also to devise means whereby any board of suitable dimensions can be converted into a hawk by the attachment thereto of the provisions hereinafter more particularly set forth.
In the annexed drawings,Figu-re 1 is a bottom perspective view of a hawk showing the application of the invention. Fig. 2 is a detail View of the handle. Fig. 3 is a view of the plate. Fig. at is a detail view of a portion of the hawk board showing the metal wear plate in position.
A represents the hawk board which is usually about twelve by twelve inches square and tapers in thickness from about four inches from each edge outward to the edges to reduce the weight.
B is a metal plate of sufficientthickness to give stability to the board and prevent warping.' This plate is long and narrow and tapers in width from a short distance from each end and has openings to receive the screws or similar fastenings a by means of which it is fastened to the board. An opening 0 is provided about the center of the plate to reing to the length of the lips e thereby facilitating the attachment of the handles to the board.
The handle is tubular and has its end notched, the portions between the notches being turned outward at about right angles to provide the. lips d which correspond in position and number with the notches b to pass through the same in the operation of attacl1- ing and removing the handle. One end of the lip is beveled to facilitate the entrance under the lips e.
A wear plate is attached to the board A opposite the opening 0 to receive the end thrust of the handle and prevent the same cutting into the soft board. Plate B is not mortised into the board but fastened on the un der side thereof crosswise of the grain and the middle portion is slightly bulged to cause the lips e to stand out a proper distance toreceive the lips d. To attach the handle the lips 11 are brought in register with the notches b through which they pass, the handle being given a turn to cause the lips d to pass beneath the lips e by which the handle is retained in place. If desired interlocking projections may be provided in the opposing faces of the lips d and c to retain in place against accidental displacement. To detach the handle the reverse of the operation just described is practiced.
opposite the said central opening and a handle removably attached to the hawk-board and having lateral extensions corresponding in position and number with the notches in the flat metal plate through which they pass 1o eral extensions to be passed through the said notches and engaged with the lips, substan tially'as described andyfor the purpose specified.
In testimony whereof I affix my signature in presence of two witnesses.
JOHN MARTIN DAVIS.
