PICK.

SPECIFICATIOLT forming part of Letters Patent No. 773,5(57, dated October 25, 1904. Applicatian filed February 16,1904. Serial No. 193,847. .(No model.)

To all whom it may concern:

Be it known that I, BUD H. LAUGHHUNN, a citizen of the United States, residing at Centralia, in the county of Marion and State of Illinois, have invented a new and useful Pick, of which the following is a specification.

The invention relates to improvements in The object of the present invention is to improve the construction of picks, and more especially the means for applying the handle to the same, and to provide a simple, inexpensive. and efficient device of great strength and durability designed for use on picks and various other toolssuch as sledge-hammers, shovels, and the likeand capable of enabling the handle to be firmly'secured to the head and of bracing and supportingthe handle,

, whereby the same is prevented from breaking at the point of attachment to the head.

With these and other objects in view the 'invention'consists in the construction'and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended, it being understood that various changes in the form, pro-. portion, size, and minor details of construction within the scope of the claims may be. resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a perspective view of a pick constructed in accordance with Fig. 2 is a sectional view taken longitudinally of the pick-head. Fig.

' 3 is a similar view taken transversely thereof.

Fig. ,4 is a detail perspective view of one of the sections of the combined clamp and brace.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates a tool-head, provided at its end portions with longitudinal openings forming. end sockets 2 for the reception of points 3, and the latter have tapered shanks 4, which frictionally engage the end sockets. The end sockets are provided with transverse slots 5,

adapted to'receive a wedge-shaped key for enabling the points to be readily driven out of the sockets.

The pick-head is provided with an intermediate handle-receivingsocket 6-, extending upward from its lower face and adapted to receive the adjacent end of the handle 7, which is firmly wedged in the socket. The intermediate handle-receiving socket is closed at the outer end, and in assembling the parts the wedge 8is started in the, handle-pbut the latter is fitted in the-socket, and as the head is forced on the handle the wedge will be driven into the latter and will expand the same against the sides of the intermediate socket. The

head is provided at opposite sides with trans- 'the pick-head, as clearly shown in Figs. 1 and 2. The vertical side edges of the approximately semitubular portions of the sections are fitted together, and the upper terminalsof the said tubular portions, which form the said shoulders, fit against the lower face of the head. The sections of the combined clamp and brace are secured to the pick-head and to the handle by bolts 13 and 14L, arranged at the inner and outer portions of the sections. The outer bolt 13 pierces the pick-head and the arms or extensions 10 of the sections 11 of the combined clamp and brace. The bolt M passes through the inner portions of the sections and the handle 7. The bolts are provided with nuts, as shown; but any other suitable fastening devices may be employed for this purpose. as willbe readily understood. The handle 7 is held inv the socket of the pick head as firmly as if it were extended entirely through the same, and the combined clamp and brace supports the handle and prevents the same from breaking at the pick-head, which forms a continuation of the said socket.

Having thus fully described my invention, What I claim as new, and desire to secure by Letters Patent, is

In a device of the class described, the combi'nation of a tool-head provided at its side faces with recesses and having a socket extending upwardly from its lower face and terminating short of its upper face, a handle fitted in the said socket, a combined clamp and brace composed of sections arranged at the side faces of the head and the handle and consisting of upper flat portions fitting in the said recesses and lower approximately semitubular portions embracing the handle and having their side edges fitted together to form a continuation of the socket, the upper ends of the semitubular portions being fitted against the lower face of the head, and upper and lower transverse fastening devices piercing the upper and lower portions of the combined clamp and brace, the upper fastening device being located beyond the handle and passing through the head, and the lower fastening device being located beyond the head and passing through the handle.

In testimony that 1 claim the foregoing as my own 1 have hereto affixed my signature in the presence of two witnesses.

his BUD X H. LAUGHHUNN.
