RILEY HERBERT PARKER, 01? WINTHROP, MASSACHUSETTS, ASSIGNOR TO GILLETTE SAFETY RAZOR COMPANY, 015 BOSTON, MASSACHUSETTS, -A CORPORATION OF DELAWARE.
v PILE WIRE.
To all whom it may concern.
Be it known that I, RILEY HERBERT PARKER, a citizen of the United States, relsidin at Winthrop, in the county of Suifo'lk and tate of Massachusetts, have invented certain new and useful Improvements in ;vember 1, 1920, by Ralph E. Thompson,
which shows and describes a pile wire and blade of the character above referred to, the wire being provided with stops which overhang the ends of the blade when in operative position and with a lateral opening into which one end of the blade is fixed during insertion and removal. The objects of my improvements are, primarily, to increase the facility with which the blade can be inserted and removed and to simplify theformation of the blade-receiving recess of the wlre.
In the accompanying drawing, Figure l is a side elevation-of a portion of a pile wire made in accordance with my invention,
Figure 2 is a plan view of the same with the blade removed, and
Figure 3, is a side view of a detachable blade shown in Figure 1.
In the drawing, 2 indicates the front or free end portion of a pile wire which is of uniform height throughout that part of its length at which the blade is located, and 3 indicates a blade which is substantially triangular in shape and has upwardly-converging front and rear edges, of which the rear edge 4 is the cutting edge. The lower edge of the blade 3 when in operative position in the wire is seated on the bottom of a blade-receiving recess which may be formed by milling a-groove 5 in the upper edge of the wire, the bottom of the groove being indicated by the dotted line 6, Figure 1', and the blade s'top at the rear end of said recess may'con-.
sist of a pin 7 passing transverselv through the wire in position to overhang the rear end of the blade. At the opposite end of the blade-receiving recess there is a transverse opening 8 provided with an under-cut front wall 9 which overhangs the front end of the blade when in operative position and prevents it from moving upward or forward, and in the particular construction illustrated this wall 9 is formed by pressing together those portions of the wlre which are sepa ratedby the front end of the milled groove 5 in front of the opening 8, thereby not only closing the groove at this point but also providing bevelled surfaces 10 on the sides of the-wire..
The blade 3 is transversely flexible and is inserted by introducing its rear end into the blade-receiving recess near the rear end of the latter, with its front end bent to one side of the wire adjacent to the opening 8,-and' then pushing it downward and rearward until its front end is in position to spring into place behind the end wall 9, whereupon the blade is released and resumesits normally fiat condition, being held in position so long as it remains flat by the overhanging wall 9 and the pin 7 at its corresponding ends. To remove the blade it is necessary to bend its front end laterally beyond one side of the end wall 9 and then draw it forward and upward out of the recess, the operations 1 advantages that the blade-receiving recess lateral opening at one end of the recess, in
combination with a flexible cutting blade having a substantially triangular shape with opening.
2. A pile "wire providedwith a blade-receiving recess a lateral opening communicating with the front end of said. recess and having an un-- dercut front wall, the wire being laterally bevelled in front of said opening,-in combination with a flexible cutting blade having av substantially triangular shape with upwardly-converging front and ,rear edges and located mainly above the top of the wirewhen seated on thebottom of the recess, and retaining means overhanging the rear end of the blade near its lower edge.
in its upper-edge and with 3. ,A pile wire provided with a time-re;
ceiving groove in'its upper'edge and with a lateralopening communicating with said groove and having an undercut front wall, said wire being of substantially uniform "height throughout the length of the groove,
in combination with a flexible cutting blade adapted to be seatedv 0n the bottomof the groove and having a substantially triangular. shape with upwardly-converging front and rear edges, and a blade stop crossing the groove at the rear end of the blade in position to overhang the latter, the groove being closed at said undercut wall by lateral deflection of the material in which the groove is cut. g
