DESIGN FOR A HANDLE FOR DENTAL INSTRUMENTS.
SPECIFICATION forming part of Design No. 32,154, dated January 30, 1900. Application filed December 26, 1899. Serial NQUMLGS L Term of patent 14 years.
To all whom it may concern.-
Be it known that I, WILLIAM E. HARPER, a citizen of the United States, residing at No. 3441 Wabash avenue, Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Design for a Handle for Dental Instruments, of which the following is a specification.
This invention relates to a design for a handle for dental instruments, and has for its object to produce a new and novel design of characteristic and distinguishing appearance that presents to the eye a design readily distinguishable from all prior designs for this purose.
In the drawings, Figure l is a side elevation of a handle, showing my design. Fig. 2 is a plan View thereof. Fig. 3 is an end elevation of one end of the handle, and Fig. at is an end elevation of the other end of the handle.
The essential feature of my design consists of an angular handle generally cylindric in form and having two end sections with substantially parallel sides connected by an intermediate curved portion having tapering sides.
As shown in the drawings, the handle comprises the cylindric end portion A and the cylindric end portion B of a diameter of about two thirds that of the cylindric portion A, the end cylindric portions being united by an intermediate curved portion 0, which tapers from the portion A to the portion 13, merging opposite ends without break or interruption to the outline of the tapered portion.
In the curved portion C, at the outer curved side thereof, is formed a notch extending substantially half-way through the curved portion, one wall D of which notch is disposed substantially at right angles to the axis of the part B, while the opposite wall E is disposed substantially at a right angle to the axis of the portion A, said walls D and E being con nected by a straight wall 11 at or about the center of the curved portion and extending longitudinally thereof.
As viewed from its end the cylindric portion B presents a flat surface outlined by two concentric circles, and the same is true of the opposite end of the portion A, excepting that the circles are of greater diameter than those outlining the part B, the end views of these parts B and A appearing in Figs. 3 and 4, re spectively.
As viewed in plan, as shown in Fig. 2, the axes of the parts A, B, and C are in a somewhat vertical plane; but as viewed from the side, as shown in Fig. l, the axis of the part A is oblique to that of the part B, while the axis of the part 0 would be substantially a curved line connecting the axes of the parts A and B through the longitudinal center of the part 0.
It will thus be seen that the handle as a whole has an angular appearance as viewed from the side, although it appears straight when viewed from the top, thus giving to the handle a characteristic and distinguishing appearance.
Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-
The design for a handle for dental instruments, substantially as shown and described.
WILLIAM E. HARPER.
