SGRBW DRIVER.
Patented Nov. 27
UNITED STATES PATENT EEICE.
GEORGE S. ALLEN AND ROBERT C. ELLBICH, OF SOUTHIEGTON, CONN.
SCREW-DRIVER.
SPECIFICATION forming part of Letters Patent No. 289,056, dated November 27, 1883,
To rtl-Z whom t may concern.-
Be it known that we, GEORGE S. ALLEN and ROBERT G. ELLEicH, citizens of the United States of America, residing at Southington, in the county of Hartford and State of Gonnecticut, have invented certain new and useful Improvements in Screw-Drivers, of which the folio-Wing is a specification, reference being had therein to the accompanying drawings, in Which- Figure l is a View of the screw-driver. Fig. 2 is a view ofthe parts of the same before the parts are put together. Fig. 3 is a longitudinal and central section of the handle and bolster, and Fig. 4. is a crosssection of the bol` ster. Figs. 5 and 6 are views of a die, and Fig. 7 is a sectional view of the bolster.
Our invention relates to screw-drivers, and its object is an improved article. The novelty is in the bolster, for the most part, and consists in the means of fastening. the handle in the same.
To enable others to make our improved screw-driver, We will give a detailed description of the sanne and of its several parts.
That part of the shank Ain the bolster, and for some distance from it, is a round steel rod, and the remaining part is made in the usual form. The tapering 'bolster Bis cast onto the shank, and has the tapering socket D, Fig. in which are the feathers a, Fig. 4, and the swell or enlargement C on its upper end, as shown in Fig. 2. r)Ehe part E of the handle F which enters the socket has the notch b, and is tapering in opposite directions, as shown in Figs. 2 and 3. The other parts of the handle are in the usual form. i
To put the bolster and handle together in our improved Way, it is requisite that the bolster be made of a duct-ile metal, or of a suit- Applcation filed September 19, 1882. (No model.)
able alloy. A good alloy for the purpose, as it adheres with great tenacity to the shank, consists of tin, one hundred parts; antimony, fifteen parts; and copper, three parts. The handle may be driven into the socket, and the swell on the bolster may be spun into the notch b on the part E of the handle. A better and more expeditious Way is to place the Vbolster in a die having a tapering hole correonto the Shanks, and that various means of 6o fastening the handles to the holsters have been used; but
What We claim as our invention, and desire to secure by Letters Patent, is-
A screw-driver having the shank A, provided with a soft or ductile metal bolster, B, cast thereon, said bolster being formed with enlargement C at the open end, and a handle, F, having a depression, b, the Whole being constructed to be set in place and then fastened by the inward swaging of the enlargement C, substantially as set forth.
In testimony whereof We affix our signatures in presence of two Witnesses.
GEORGE S. ALLEN. ROBERT C. ELLRICH.
