PROCESS OF FORMING OIL-CUPS.
Specification of Letters Patent.
Patented Feb. 28, 1907.
Application April 7 Serial NO- T 0 all whom it may concern.-
Be it known that. I, JAMES Townes, a citizen of the United States, and a resident of Albuquerque, in the county of Bernalillo and Territorv of New Mexico, have invented a new and Im roved Process for Forming Oil- Cups, of which the following is a full, clear, and exact description.
This invention is an improvement in processes for making oil-cups, and has amon other objects to reduce a cup which shall be better than t rose formerly devised and which can be more speedily produced and at a smaller expense and form all of the cups with exactness and uniformity.
Generally stated, the process consists in taking a round bar of iron or steel, upsetting the end in a die of suitable fashion to form the base and stem of the cup and thereafter welding a pipe thereto and further shaping the upset portion in a second set of dies to form the'com lete cu Reference 18 to be liad to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.
Figure l is an elevation of a set of dies used in carrying out my improved process, one half of the lower or female die being shown. Fig. 2 is a lan view of the female die with the upper ialf removed. Fig. 3 is a frogmentary sectional elevation of the dies and the work at the end of the first step in my improved rocess. Fig. 4 is a fragmentary 'sectional c evation of the other set of dies and the work at the beginning of the second step of my improved roeess. Fig. 5 is an elevation of the bar a ter the first upsetting operation. 1 1g. 6 is a section of a pipe forming the oil-cup )ody, and Fi 7 is a longitudinal section of the parts sliown in Figs. 5 and 6 after the have been welded and shaped to form tie body portion of an oilcome together, thus producing a die in which the first step of my improved process takes place. Cooperating with this die is a male die 6, of such size as to fit the boring 4 and having a shank 7 at its upper end adapted to fit in a socket in the plunger of a steam-hammer or other suitable press. At the opposite end of the die a hole 8 is bored, similar to and of the same size as the hole 3 and leading into a counterbored portion 9 in the upper half of the die and of the size of which the body of the cup is intended. Between the borings 8 and 9 and in the lower half of the die is an undercut hexagonal portion 10, connecting with the hole 8 by a counterbored portion 11, giving the exact conformation desired for the base of the cup and forming a die in which the second step of my process is performed. Cooperati with this second die is a male die 12, of t to diameter and len th intended for the interior of the cup, having a centering-punch 13 at its lower end and an air-vent 14 extending through an enlarged portion 15 of the die and of a size to fit the borin 9 said die having a shank 16 similar to the s ank 7 of the die 6.
In carrying out my process the female dieblocks are secured to the anvil-block of the machine and the male dies are secured in its plunger. A bar 17 of iron or steel heated to a welding heat is then inserted in the hole 3 and projects slightly above the conical undercut portion 5 o the first set of dies. When the die 6 descends, the end of the bar is upset, formin r a conical head 18 on the bar, as shown in Fi 5. This bar is placed in the second set 0 dies, as represented in Fig. 4, and a pipe l9,heated to a welding heat, is inserted in the counterbore 9 and rests on the periphery of the conical head sli htly below the top of the undercut hexagonal portion 10 of the die-block. When the die 12 now descends, the pipe will be shortened and thickened to fitt e male and female dies and the ed es of the conical head 18 turned u to take the conformation of the hexagona recess and weld the pipe to the head. The head 18 will also be recessed and centered for borin v and the metal forced into the counterl.)()l'(( portion ll, thus finishing the cup 20, which is afterward cut from the bar 17.
Bv first upsetting the end of the bar 17 in the form of the conical head 18 I am enabled to form the cup by less labor, and only one heating is required for this part.
Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A process for forming oil-cups, which consists 1n first heating and upsetting the end of a bar to form a conical head, lacing said bar and its attached conical hea in a pair of dies having the conformation of the finished cup, then inserting in the dies in contact with the tapered portion of the conical head, a heated pipe to form the body portion of the cu" and upsettin said pipe and head, at a we ding heat to we (1 them together.
2-. A rocess for forming oil-cups, which consists in heating a bar of iron or steel, forging a conical hea thereon, placing the head in a set of dies insertin a pipe to rest on the periphery of the conical head, upsetting the two parts at a welding heat'to'weld them toether, and then cutting the cup from the bar or the purpose s ecified.
3. A process or forming oil-cups, which consists in formim at the end of a bar of iron or steel, a head, placing the head in a set of dies, inserting a pipe, having an outer diameter less than the body portion of the finished cup which it forms, in the dies in contact with the head, and upsetting the pipe and head at a welding heat to weld them together.
Intestimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
