I Specification of Letters Patent.

Application filed December 17,1910. Serial No. 597,901.

f all whom it may concern:

Be it known that I, GEORGE W. PALMER, a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and oil can be properly fed to thezdie at the.

proper vplaeewithout stopping the threading operation and. thus saving time and preventing injury to the work and tool for the-wantof oiling. j I Anotherobject of my invention is to provide an oiler at all times carried by the tool and having certain details hereinafter fully set forth.

In the accompanying drawings: Figure 1 is an elevation of my improved oiling handle applied" to a die-stock. Fig. 2 is a longitudi-v nal cross-sectional view of the handle, and Fig. 8 is. a cross-sectional view takenon the line A B Fig. 2.

Referring now to the drawings, l iepre sents the hollow metal handle of a die stock which 'is'screwed into the stock as indicated at 1, and in which is formed theoil-chamber 2 by the two partitions 3 and 4, access being had to said chamber for filling or emptying through a suitable screw-cap covered hole'5;

A piston 6 having the rod 7 is operatively mounted through the partition 3, and rod 7 operating through the artition 4 in which latter a tight joint is e ected by means of a screw-threaded. stufiing gland 8 having radial holes 9 in the upper end-thereof for the purpose of receiving a tool for rotating it and adjusting it up or down.

The lower end ofthe portion 6 is somewhat conically shaped forming the beveled surfacelO, which engages a similarly shaped seat-in the lower surfaceof the-partition 3.

About the base of the conical portion of the piston is carried a circular washer 11 to act as an additional valve seat and engages the rim of the seat formed in the lower surface of the partition 3, thus a tight joint is insured between the partition and the piston, when the latter is in its uppermost position.

A plurality of longitudinal ports 12 are the desired formed in the outer surface-of the piston 6 which are sufficiently long to extend somewhat above theupper surface of the partition 3, and within the oil chamber 2, when the piston is. upwhich will allow the ports to readily fill with oil therefrom and then when the piston is lowered the communi cation (with the chamber 2 will be closed and,

the oil in the ports 12 allowed to dischar e within the kchamber 13 formed between t e end of the handle and the dished washer 14.,

within ,the stock 15 and upon which the handle .1 is. tightly screwed. A feed dpipe s to -16 is attached to the washer 14 and lea place of discharge over] the die 17.

A finger button 18 is attached "the upper 'end of the piston 7, by which the.

latter is depressed when desired" and the spiral spring 19' is interposed between the. button 18 andthe upper end of the gland 8, whereby the plston and rod are retained normall-y at their upward extremity. The piston rod 7 is made hollow a large portion of its length from the upper end forming the hole 20 therein and just below the button 18 is the lateral hole 21 through the side of the piston rod 7, and communicating with the hole 20 and a similar lateral hole 22. is formed in the side of the rod 7, at a point just above the upper end of the chamber 2, when the piston and rod are up. Normally thechamber 2 is sealed, but when the piston and rod are depressed the oil is discharged from the ports 12 {and air admitted above the oil inthe chamber 2,'through the holes 22, 20 and 21 so that a vacuum is not formed in'the chamber 2 by the discharging of the oil. v

The hole 20 extends considerably below thelateral hole 22'to provide for the collection of dust or dirt without plugging the communication between the outer air'and the chamber, and extends up through the end of the rod 7 to admit of readily cleaning with a wire or the "like. The upper end of the handle 1 is cut away as at 23 for."

convenient access to the button 18 and the operation of the device. p I

Having thus described my lnvention, what I claim and desire to secure by Letters Patent is:

1. The combination with'a die-stock, (if a hollow handle for operating the stock and in communication with the dies carried by the stock, an oil containing receptacle end of the piston rod having an openingv extending longitudinally therethrough and having a lateral opening communicating therewith and normally above the upper end of the oil receptacle, whereby upon the downward movement of the piston-rod to feed the oil to the die the upper end of the.

receptacle is in communication with the outside atmosphere.

2. The combination with a die stock, of

a hollow handle removably secured in said stockand in communication .with the dies carried by" the stock, a receptacle formed in said hollow handle and having a contracted lower end, a piston controlling saidcontracted lower end, a piston rod carried by.

the piston and extending out through the upper end of the receptacle and having operatin means carried by its upper end on the,

outslde of the receptacle, said piston rod having an opening extending longitudinally of its length and having a lateral opening communicating therewith, which is norv mally above the upper endof the receptacle, substantially as shown and described.

3. The combination with a die stock, of

a hollow handle removably secured in said stock, a receptacle formed in saidhandle and having a contracted lower end, the lower face of said contracted end being beveled to form a vseat, 'a piston passing through the contracted end of the receptacle and closing the same and having a beveled lower end to rest upon the said outer face of the said piston having longitudinal grooves, the lower ends of which areabove the lower end of the receptacle and the upper ends in communication with the receptacle, and means for forcing the piston downwardly whereby the lower ends of the grooves are brought into communication with the dies and the upper ends out of communication with the receptacle, whereby a predetermined amount of oil is fed to the dies.

4. Thecombination with a die-stock havmg handle receiving sockets internally screw-threaded and in communication with the dies, a plate resting in said sockets and the conically shaped plate therein, a receptacle formed'in the handle for containing oil and means for feeding a predetermined amount of oil from the receptacle to the said conically shaped plate. v

5. The combination with a die stock having handle receivingsockets in communication with the dies, a hollow handle screwed into said sockets, an oil containing receptacle formed in 'said handle, a piston within the handle and controlling the communication-between the oil-receiving receptacle and the dies, a piston stem carried by the piston and extending out through the upper end of the receptacle, a spring surrounding said stem and normally holding the piston rod in its upward position, said iston having "grooves in its outer face whlch, when the piston is in its upward position, are in communication with the receptacle, the upper end of the valve stem having a longitudinal opening through a portion thereof, said stem having a lateral opening communicating therewithand above the receptacle when the piston is in its upward. position, whereby a predetermined amount of oil is fed to the dies upon the downward movement of the piston rod and air is fed to the upper end of the receptacle above the oil.

In testimony whereof. I hereunto afiix my signature in the presence of two witnesses. GEORGE WV. PALMER. Witnesses:

WM. M. GBAVATT, S. GEo. STEVENS.
