SPECIFICATION forming part of Letters Iatent No. 656,498, dated August 21, 1900.
Application filed October 31, 1899- S erial No. 735,381. (No model.)
To all whom it may concern:
Be it known that 1, WILLIAM PERRY Bnv- INGTON, a citizen of the United States, and a resident of Escondido, in the county of San Diego and State of California, have invented new and useful Improvements in Picks, of
which the following is a'full, clear, and exact description.
My invention relates to picks, and has for its object to provideimproved and very efli: cient means for attaching a pick to its handle so as to prevent the pick or point from working loose. To this end I employ the particular construction and arrangement of parts hereinafter described and claimed.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.
Figure 1 is a sectional elevation of my improved pick with parts in section on the line 1 1 of Fig. 2. Fig. 2 is a vertical section on the line 2 2 of Fig. 1. Fig. 3 is a perspective view of the head and clamp forming part of my invention, and Fig. 4 is a sectional plan on line 4 l of Fig. 2.
The complete tool comprises a handle A, a
head B, a screw-bolt O, a nut D, a clamp E,
a key F, a wedge G, and a point or pick H.
The Wooden handle Ais cylindrical or of any other approved shapein its main portion andhas a tapered upper end A, perforated transw.
versely. The head B has an upper portion of I shape in horizontal cross-section, form-i 1ng vertical channelsB on the oppositesides of the head. The lower end of the head forms a socket B for thegreception of the tapered; end A of the handle A and has two longitudinal slits B to facilitate the insertion of the handle. The socket portion of the head is also perforated transversely, as at B, for the reception of the screw-bolt O, which, with the nut D, serves to securely connect the handle- A with the head 13. The not provides a ready means for tightening at any time the connection of the handle with the socket of the head. The central member or web of the I-shaped portion of the head'is provided with a rectangular cross-aperture E the upper wall B of which is inclined, as will be seen best in Fig. 2. The clamp E is substantially U- shaped, the width of its parallel members E being equal to that of the channels B, while its central member E is wider, forming shoulders E The end members E have apertures Efiadapted to register with the aperture B The pick H is of substantially the usual shape and has a reduced central portion H, corresponding in width to the upper end of the head B and adapted to be received between the parallel members E of the clamp E. The pick is therefore held between the clamp E and the head B and is clamped in position by the key F and Wedge G. Of these the key F has bent ends F to fit over the outside of the clamp members E, the key being passed through the apertures E and B and engag ing the lower walls of the apertures E Then the wedge G is inserted above the key F in the same apertures and in contact with the inclined wall B and the wedge isdriven in, forcing the clamp to slide down in the channels B until the central portion H of the pick is firmly clamped between the upper end of the head 13 and the central member E of the clamp E.
It will be observed that the clamping parts are entirely of metal, andI thereby avoid the liability to looseness, which is a defect of all constructions in which wedges or other tightening devices engage Wooden surfaces.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination of the handle, the head having at its lower end a split socket for the reception of the handle, and at its upper end a solid portion I-shaped in horizontal crosssection, forming longitudinal channels in 0pposite sides of the head, said channels being connected by an aperture extending through the central member of theI-shaped section, the bolt passing through the handle and through the split socket, the U shaped clamp the side members of which slide in said channels and have cross-apertures registering with that of the head, and shoulders projecting over the parallel end members of the I-shaped section, the pick held between the upper end of the head and the central member of the. clamp, a key extending through the apertures of the clamp and head and having bent ends engaging the clamp members exteriorly, and a Wedge extending through the same aper-- 'tures and engaging the key and the head.
