MANUFACTURING CAR-COUPLING PI NS.
SPECIFICATION formingpart of Letters Patent No. 273,417, dated March 6, 1883.
Application filed November-1,1881. (No model.) 7
To all whom it may concern:
Be it known that I, JOSEPH WHILE, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Manufacturing Oar- Ooupling Pins; andI do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.
My invention relates to car -coupling pins; and it consists in the peculiar manner of manufacturingthe same, as will be hereinafter fully set forth and claimed. I
In the drawings, Figure] is a side elevation of one form of machine used to manufacture the pins. Fig. 2 isv an end view of the same, showing the preferred manner of grooving the rolls. Fig. 3 shows a pin after having passed through the rolls, and Fig. 4 illustrates a tinished flat pin with rounded edges.
A is a suitable frame, the same being provided preferably with three rolls, B,O, and I)- The rolls B and (l are geared togetherin such a manner that they revolve in the same direc tion, as indicated by the arrow, Fig. 1. I
The roll Disadjustable and provided with two movable or sliding bearings, E, one on each side of the roll D, preferablyoperated by means of screws a and suitable gearing so connected that both ends of the roll I) are moved the same distance. The rolls B, G, and D are grooved, as shown in Fig. 2viz., to conform to the shape'of the pin intended to be made.
My process is as follows: I take a piece of metal, somewhat larger in diameter and shorter than the pinis to be. This metal-preferably iron or steelis subjected to heat until it has become sufficientlyhot. It is then dropped lengthwise between the rolls B and D, and the roll B acts to draw it down until it comes in contact with the roll O. The roll D is now fed up until the pin is drawn to the desired shape.
After the pin is rolled to the desired shape the roll D is caused to move back and the pin falls to the floor or any suitable receptacle beneath the machine. During the process of rolling I prefer to cause water to fall on the heated metal, and thus produce a better finish and a tougher or stronger pin.
The foregoing process is all that is necessary pins,cousisting in rolling the metal to form the complete shank and head and shoulder, and
then subjecting the shank portion to compression and flattening its opposite sides, substantially as set forth. T
In testimony whereof I have signed my name to-this specification in the presence of two subscribing witnesses. V
