This invention relates to masons and plasterers tools such as hawks, floats, darbies and the like.
In the past masons and plasterers tools,
l such as hawks, floats, darbies and the like,
I and destroys the smooth, even surface, which is desirable in the tool. Such tools and particularly hawks have also been made of aluminum. This results in a very light tool but one which does not retain a sufliciently rough surface to hold the plaster and such'metal tools are also very expensive. The present invention obviates the disadvantages of the prior devices and provides cheap and eflicient masons and plasterers tools.
According to the present invention, the face of the tool is made of any suitable material such as, for example, fiber, composition and the like, and the handles are attached by means of continuously tapered screws or bolts preferably of soft metal, so that as the surface wears down the fastening still continues to hold. It is thus possible to use any desired material for the face and the tools can be made readily demountable where this feature is an importance as, for example, in the case of hawks.
In the drawings Figures 1 and 2 illustrate a plasterers hawk in (perspective and cross-section respectively; an
Figures 3 and 4 similarly illustrate a float.
The hawk shown in Figures 1 and 2 consists in a face board 1 which may be of fiber composition or any other suitable or desired material. The face board is provided with a central hole which tapers continuously and in which a tapered slotted bolt head or nut 3 of soft metal is mounted, the taper corresponding to that of the hole. The bolt head 3 is preferably hollowed out as indicated at 11- in Figure 2, on the outer side thereof. A handle 2 which may be of wood or any other 192a SeriaLNo. 205,555.
suitable material fits over the neck of the bolt head 3 and isfastened thereto by the bolt 4. The. handle is readily demountable for carrying and the hawk can be made with a f21tce board of any desired thickness or materla I g It is not necessary, in many cases, to provide a bracing spider or cleats to stifien the face board 1, although in some cases this may be desirable and may be utilized, in which case the spider may be attachedto the face board by a plurality of taper fastenings, as will be clear to those skilled in the art. In the construction shown in Figure 2, the face board 1 is braced by means of a plate 9 preferably of metal interposed betweenthe handle 2 and the board. The plate 9 is formed with a marginal. flange as shown in Figure 2, and a pad 10 preferably of rubber, is applied to the plate within this flange. Both the plate and pad are held against the adjacent face of the board by means of the handle 2 which bears against the outer face of the pad. The pad 10 forms a cushion for the hand when the tool is in operation.
Figures 3 and 4 illustrate a float in which a face board similar to that shown in Figures 1 and 2 but of different shape is provided with'two tapered holes, through which continuously tapering screws 5 pass and screw into a handle 6. The head of the screw 5 is hollowed out or made concave on the outer side thereof, as indicated at 12.
Wear of the face board will result in a' corresponding wear of the soft metal screw head, which does not thereby lose its hold as in the case of an ordinary screw which pulls out as soon as the head is worn through. Because of the fact that the bolt head or nut 3 and the head of the screw 5 are hollowed out on the outer side thereof these parts will wear down much more readily to correspond with the wearing down of the board 1.
Darbies or other masons tools may be built in a similar manner, utilizing the fastening of the present invention. 7
,What is claimed as new is:
1. A masons or plasterers tool comprising a face board and a handle therefor, said face board having a tapered opening extending entirely therethrough from its operative face to its rear face, and a fastening means for said handle, said fastening means including a member completely filling, and conforming in shape to said opening, said member being formed of relatively soft metal and having its outer faee eoneaved.
2. A masons or plasterers tool comprising a face board having an openingtapered in a direction from the oiits'ide to the inside of said board, a handle and means connected with the handle for securing the handle to the face board comprising a clamping meme her tapered in the same direction as said opening and engaging in the opening in conmet with the eriph'er'al wall thereof, said clamping mem er having its outer face concaved and adapted to be Worn away with said face board;
3. A masons or plasterers tool comprising a face board having a face with which to work plastic material and a tapered opening extending entirely therethrough from its operative face to its rear face, a handle for the tool arranged substantially perpendicular to the face board,and fastening means for removably securing the handle to the face board, said fastening means including a bolt passing through a longitudinal bore in the handle, and a clamping member secured to said bolt and engaging in and conforming to said tapered opening.
