AUTOMATIG-OILING MULTIPLE-DIE STOCK.
Specification of Letters Patent.
Patented Mar. 10, 1914.
Application filed February 3, 1913. Serial No. 745,840.
To all whom it may concern Be it known that I, HERMAN J os. Sonn- ZEN, a citizen of the United States, res1dmg in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Automatic-Oiling Mult ple- Die Stocks, of which the following 1s a specification. l
This invention pertains to die stocks and its object is the production of a die stock j having a plurality of dies and an oiling; device therefor that is automatic in its ac- 1 tion.
It is a further object of this invention to so arrange the dies and the structural parts that they will balance about the a rlsof the pipe or rod irrespective of the die 1n use, insuring smoothness of actlon; to provlde a device having a contact with the pipe or the rod in addition to the die whereby the perpendicularity of the stock to the pipe or rod is assured; and to provide a device in which the dies are readily removed and inserted and quickly secured when in place.
It is also an object of this invention to provide an oiling device therefor which will feed a predetermined quantity of 011 for every rotation and give a poslt-ive impetus to the oil to counteract the centrifugal force generated by the rotation of the die stock.
Another object of this invention is to provide a die stock in which the above objects will be attained that will be of simple construction, reliable and inexpensive.
Other objects will appear from the following description and accompanying drawing, in which Figure 1 is an elevation of a die stock, the handle levers being broken off, showing the external appearance of the stock having the oiling device as a part thereof. Fig. 2 is a top elevation of the stock shown in Fig. 1. Fig. 3 is a vertical section on the line 3-3 of Fig. 4: disclosing details of the oiling device. Fig. 4c is a horizontal section of the die stock through the dies, on the line H of Fig. 3. Fig. 5 is a vertical section taken on an axial plane perpendicular to that of Fig. 3, on the line 55 of Fig. 2. Fig. 6, is an elevation of a part containing the means for controlling the oil flow. Fig. 7 is a top view of the part shown in Fig. 6. Fig. 8 is a bottom viewthereof. Fig. 9 is an elevation of a part attached to that shown from above in Fig. 5 of one of the members forming the oil and feed-controlling means; F 11 is a plan view, looking upwardly in Fig. 5, of the sleeve which holds the dies in place; and Fig. 12 is a side elevation of the member shown in Fig. 11.
The die stock forming the subject of this invention comprises a body 1 for supporting the dies 2 and to which the operating levers are attached. The body 1 is hollow and polygonal in cross section, each side of the polygon being formed by a rectangular wall. Alternate walls of the prism are provided with the die-holders 40, which holders have the inturned flanges 41. Between these sides 4-0 fit the dies 2. The walls are pierced with large openings 4-2 to permit the insertion of a pipe or rod through them and these openings 42 have thickened edges 43 to hold the dies firmly against the flanges 41. In the walls opposite these walls are openings 1 which are in .an axial line with the openings 3 in the dies 2 and are of a size to fit the same size of pipe that the die is intended to cut or thread. Projecting from the upper end of the prism is a circular flange 14: which forms a stop for preventing movement of the dies. A removable sleeve 5 on the end 6 has projections 7 that extend beneath the dies and lock them in place. A nut 8 holds the sleeve in place.
In the end 6 of the stock body a usual type of handle lever is mounted. In the other end 9 is mounted a hollow lever 10 formed as a reservoir for the oil and also containing the controlling feed means. The hand hold 11 on the outer end of the lever 10 is hollow and forms a continuation of the oil reservoir. In the ends of the hand hold are threaded caps 12 and 13 and the cap 12 has a projection 1d whereby it may be unscrewed. By unscrewing this cap 12 it is possible to fill the reservoir.
In the end of the lever 10 that is inserted into the stock body is the oil feed controlling. means. This comprises a cylinder fitting in the lever end and made in two parts, 15 and 16 for ease of construction. A dovetail tongue 17 fits in a groove 18 of the part 16" the tongue being a part of thecylinder 15- and thus the parts are held together. The part 16 is screw threaded in the lever end and carries a flange 19 that extends beyond the edge of the lever end and retains a washer '20 that contacts with the stock body.
A collar 21 on the lever part projecting beyond the stock is secured by a set screw 22 and rests on the outer end of the stock. The lever is thus rotatably held in the stock end, but it is made to fit tightly so that when turned to some angular relation to the stock, it will remain in that relation.
The end of the cylinder 15 projecting into the lever reservoir is hollowed into a cup shape 23 to direct the oil. From this leads an ellipsoidal shaped chamber 24; inclined so as to pierce the side of the cylinder. A channel 25 of uniform diameter extends through the remaining length of the cylinder and is connected to the chamber by a curved portion 26 whose opening into the chamber is somewhat smaller than the di ameter of the channel. A pocket 27 is formed in the channel adjacent this curved portion. An L-shaped channel 28 in the part 16 forms a continuation of the channel 25 and opens at the side, extending through the lever wall as shown. This opening 29 is in a plane with circumferential openings 30 formed in the stock. From these openings lead ducts 31 through the stock body, there being one duct for each die. The material inclosing the ducts projects above the surface of the stock and in the external ends or openings of the ducts are inserted rotary valves 32. A branch duct 33 leads from each of these ducts through the stock body to the dies; and a duct 33- in the die opens from the branch duct and leads to the cutting edges. Each valve 32 has a beveled end 34 which extends over the branch duct 33 to close it when turned adjacent to it. \Vhen rotated, it uncovers the branch duct and leaves a free passage from the duct to it. A pin 35 projects into a circumferential groove 36 in the valve and thus holds it in place.
In the ellipsoidal chamber is a ball 37 large enough to close either end of the chamher. The opening in the side of the cylinder where this chamber pierces it is large enough to permit the insertion of the ball. In the channel of uniform diameter is another ball 38, slightly smaller in diameter than the channel so that it is movable therein.
This completes the enumeration of the parts of the device here illustrated as the preferred embodiment of my invention. It is to be noted, however, that the pocket extends in a direct-ion opposite to that of stock rotation when cutting and the ellipsoidal chamber is inclined in the same direction. The position of the lever with respect to the cutting die in use so as to secure proper oil channel connection is indicated by the projection on the hand hold relative to the stock body.
In operation, the lever is first turned so as to. secure proper connection of the oil channel with the duct that leads to the die to be used. WVith the lever in the vertical position shown in Fig. 3, the ball valves will close the lower ends of the chamber from the reservoir. No change occurs in the position of the parts while the stock is being rotated in the direction for cutting shown by the arrow on Fig. 3, until the lever holding the oil is past the horizontal position. The ball valves then roll to the other ends of the chamber and channel and close them. The balls retain this position until the lever is past the lower vertical position when the smaller ball rolls into the pocket 27. Further rotation causes the larger ball to roll toward the first end of the chamber to close and the oil to flow into the channel. lNhen the die stock nears the first vertical position the smaller ball rolls out of its pocketupon the oil in the channel, giving it a sudden blow and an impetus toward the die. This cycle is repeated for every revolution of the stock and lever when cutting. When the die stock is rotated in the opposite direction, it is possible and the usual practice to give considerable rotary speed thereto, and the centrifugal force thus generated is sufiicient to cause the oil to recede into the reservoir.
It is to be noted that with the use of three dies or any odd number, symmetrically spaced in the die stock and the supporting openings between the dies the weight is al ways balanced about the axis of the die 1n use. A smoothness of action is the result that aids materially in the ease and convenience of use and tends to promote the eflicient operation of the oiling device.
The embodiment of my invention thus described and illustrated in the drawing is the preferred form of my device. Changes may be made therein, however, without departing from the scope of my invention as defined in the appended claims.
Having thus described my invention, what I regard as new and for which I desire protection by Letters Patent, is
l. A device of the character described, comprising in combination: a stock, said stock being polygonal in shape, alternate walls of said stock having projecting sides; and a flange extending from one end of said stock; dies mounted between said projecting sides and flange; and a sleeve removably secured on the other end of said stock to retain said dies in place.
