UNITED STATES PATENT OFFICEo CHARLES DISSTON, 0F PHILADELPHIA, PENNSYLVANIA.
IMPROVEMENT lN PLASTERERS TROWELS.
Specilication forming part cf Leiters Patent No. 52.355, dated April 0, 1875 application filed February 16, 1875.
To all 'whom fit may concern:
Be it known that I, CHARLES DissToN, of Philadelphia, Pennsylvania, have invented an Improvement in Plasterers Trowels, of which the following is a specification:
The object of my invention is to make the I will now proceed to describe, reference being had to the accompanying drawing', in which- Figure l is a transverse section ofthe blade Vof an ordinary trowel for plasterers; Fig. 2, a
side view of my improved trowel; Fig. 3, a transverse section ou the line l 2, and Fig. 4 a perspective view of the blade.
In making plasterers7 trowels, it* has been usual to take a blade of steel of uniform thick ness, rivet it to the frame B of the handle, and then grind and polish the surface. Asfit is essential that the blade should be thin, the countersunltheads a ofthe rivets, as shown in the sectional veiligl, hadnJ very insecure hold ofthe blade, which was liable to be detached-a difficulty which I overcomein the following manner: The handle consists, as usual, of a metalfi'layge, B, of malleable cast-iron, this frame having a tang onto which is driven the`wooden gripa@ rlhe blade A, instead ofbeing ot"u'niform thickness, is reenforced by a longitudinal rib, situated midway between the opposite edges of the blades, the rib being of the same width aspen, it' desired, wider than, the lower portion of the frame B. Instead of the rib terminating4 abruptly at the ends x x of the frame, I prefer to reduce it in thickness until it emerges into the upper surface ofthe blade, at or near each end of the same. This re-ent'oroing rib forms part ofthe blade, and may be most readily formed on the same by the process of rolling the blade and rib simultaneously. The frame B is iitted to the rib ebend is secured to the same, in the present instance, by three rivets. (Shown by dotted lines n1 Fig. 2.5 ltwill'be evident that the rib will permit the use of substantial heads for the rivets, which will have a more secure hold of the blade than ot a bladewyhich is of uniform th lckness throughout, and in connection with which rivets with very slight heads must be used; at the same time the rib in no way interferes with the special requirement of the trowel, that is a thin blade.
I claim as my invention and as a new manufacture- A plasterers trowel having a blade re-enforced by a central longitudinal rib, e, adapted to the frame B of the handle, all substantially as set forth. N
In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
