UNITED srnfrns VPATENT OFFICE.

Speccaton of Letters Patent.

Patented May 22, 1906.

Application led July 25, 1905. Serial No 271,127.

To a/ZZ whom t may concern: llnLBe it known that I, MATTHEW G. CORNELL, Jr., a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Im proved Stock and Die, of which the following is a full, clear, and exact description.

The purpose of the invention is to provide a construction of stock and die wherein the die is provided with openings in its side edges leading directly to the threaded aperture for the reception of the article to be threaded and wherein the socket ofthe stock receiving the die is correspondingly slotted or is provided with corresponding openings, enabling a lubricant to be readily introduced through said openings to the cutting-threads of the die where they are in engagement with the article being threaded.

Another purpose ofthe invention is to provide the body of the stock with end sections curved to extend beyond the longitudinal plane of the die-carrying face of the body, `which curved sections terminate in sockets for handles, said sockets being in longitudinal alinement with each other and with the said die-carrying face of the body portion of the socket.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

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 isa plan view of the socket containing the improved die. Fig. 2 is a longitudinal section taken practically on the line 2 2 of Fig. 1. Fig. 3 is a transverse section taken substantially on the line 3 3 of Fig. l, nd Fig. 4 is a detail perspective view of the A represents the body of the stock, the ends 10 whereof are forwardly curved or curved in the direction of the die-receiving face of the stock. The ends 10 terminate in sockets 11, which are in longitudinal alinement with each other and are likewise in lonitudinal alinement with the die-receiving face of the body of the stock,iand the said sockets 11 are adapted to receive handles of wood or of metal. By so curving the body of the stock and projecting the handles beyond the outer or front face of the stock the tool can be much more effectively used and there 1s but little danger of the handle coming in contact with the bench to which the work is secured.

At the central portion of the stock at what may be termed its forward face a rectangular Vsocket B is formed, which socket receives the die C employed. This socket at its forward open portion is closed by a coverplate 12., having the customary opening 13 therein for the'passage of a die, and the said cover-plate l2 is pivoted to the stock by means of a suitable pivot-pin or screw 14 and is held closed by means of a bolt 15 and accomplanyin'g thumb-nut 16, as is customary. At t e rear of the central socket B or die-receiving chamber of the socket a collar 17 is formed, being in communication with the said die-receiving chamber or socket B, and the said collar or sleeve 17 is adapted to re ceive a bushing 18, having any suitable-sized opening 19 therein, the said bushing' being held in place in the said collar by means of a set-screw 2O or its equivalent.

At the rear portion of the body of the socket opposing openings 21 are produced extending into the sleeve 17, through which openings the material removed by the die will drop7 thus freeing the stock and die and leaving the tool always in order.

The die C, which is shown in detail in Fig. 4, is provided with the customary threaded opening 22, adapted to produce threads on a pipe, bar, bolt, or the like; but in addition to this customary threaded opening 22 the pipe is provided with a number of openings 23, preferably four in number, and said openings are also preferably located at the corner portions of the side edgesof the die, and said openings 23 are in vdirect communication with the threaded central opening 22. The stock A at its front central portion is provided with openings 24, adapted to register with the openings 23 in the die, so that when the stock and die are in operation a lubricant may be introduced through the openings 24 in the body of the stock and the openings 23 in the die and applied directly to that portion of the article which is being threaded, thus rendering the task of cutting threads much less arduous than heretofore. The openings 23 in the die are separated by walls 25, and the threads at the central openings 23 are produced in the inner end portions of said partitions.

Having thus described my invention, I

IIO

claim as new and desire to secure by Letters Patentl. In combination, a stock having a diereoeiving socket, a die having a threaded opening, within the socket, the die and stock being provided with registering openings Jforming a Communication between the side surface of the-stock and the threaded opening of the die.

2. In a stock and die, a stock provided with a die-receiving chamber and openings in its side portions leading into the said chamber, and a die fitted to the said steek,

which die is provided with openings in the corner portions of its side edges, said openings being in direct communication with the threaded openings in the die and the openings in the die being opposite the openings in the stock.

In testimony whereof I have signed my naine to this specification in the presence of two subscribing witnesses.
