DENTAL BROACH.
SPECIFICATION forming part of Letters Patent No. 717,594, dated January 6, 1903.
Application filed February 15, 1902. Serial No. 94,267. (Ila model.)
To all whom, it may concern.-
Be it known that I, WILLIAM .LMILES, J r., a citizen of the United States, residing at Middletown, in the count-y of Butler and State of Ohio, have invented a new and useful Dental Broach, of which the following is a specification. v
My invention relates to certain improvements in the construction of dental instruments, and hasfor its principal object to provide a novel construction of broach, as hereinafter described, and particularly pointed out in the appended claim.
In the accompanying drawings, Figure 1 is a face view of a dental broach made in accordance with my invention. Fig. 2 is a similar view, partially in section, illustrating a broach having an engaging surface of somewhat diiferent character.
In carrying out my invention I employ a drawn steel wire of uniform diameter throughout its entire length. The wire is out into sections 1 of the proper length and is slightly pointed and provided with suitable barbs 2, the barbs and points being preferably formed at a single operation by means of a suitable stamping-die, the barbs being of any desired form or size to best suit the purpose for which they are intended.
In order to form a suitable handle by which the tool may be manipulated without materially diminishing its flexibility, I provide the upper portion of the Wire with a wrapping formed of a section of wire rolled or otherwise tightly wound around said wire 1 by any suitable machinery, the covering-wire being wound so tightly that any auxiliary soldering, brazing,or other auxiliary securing means will forms the handle is indicated at 3 in the drawings, and it will be noted that the lines of the coil are substantially transverse or at a right angle of the length of the wire 1, so that they will not interfere with any bending movement of the handle. For convenience the upper ends 4 of the wrapping may extend slightly over the upper end of the wire 1 to prevent the handle from slipping down on the wire when the tool is being inserted in a nerve-cavity.
In some cases the form of the operating end of the tool may be changed, as shown at 2 in Fig. 2. section of wire is passed between rollers and slightly flattened, its edges being provided with'barbs, and the flattened portion is then twisted after the manner of an auger.
The instrument as now manufactured is freely flexible from end to end, there being but little difference in the resistance ofiered to bending by the wrapping which forms the handle, and thus adding greatly to its usefulness and durability.
The length of the handle-wrapping in proportion to the length of the instrument may be increased or diminished in accordance with the character of the operating-surface, and various other changes in the form, size, and minor details may be made without departing from the spirit or sacrificing any of the advantages of my invention.
Having thus described my invention, What I claim is A dental broach comprising a practically straight untwisted section of wire of uniform diameter from end to end and freely flexible throughout its length, and a handle portion formed of a section of wire wound or coiled approximately at right angles around the untwisted wire and forming a freely-flexible handle.
In testimony that I claim the foregoing-as my own I have hereto affixed my signature in the presence of two Witnesses.
