MANUFACTURE OF DRAW-HEADS FOR RAILROAD-COUPLINGS.
Specification of Letters Patent.
Patented Nov. '7, 1905.
Application filed October 13, 1904. Serial No. 228,268.
To (ZZZ whom it may concern:
Be it known that I, WILLIAM L. JAooBY, a citizen of the United States, residing at Maywood, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in the Manufacture of Draw- Heads for Railroad-Couplers, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part thereof.
My invention relates to the manufacture of railroad-couplers, and has for its object to provide a draw-head which will be provided with stop-blocks below the pin-holes, while at the same time provision is made for the usual method of clearing the pin-holes by driving a drift through them.
With this end in view my invention consists in casting the draw-head of malleable metal and with a projection cast integral with the draw-head extending from the lower side of the head adjacent to the lower pin-hole and in subsequently bending said projection so that its end will extend beneath the pin-hole and form a stop-block for the pin.
By preference my invention also includes the step of driving a drift through the pinhole to clear and true it previous to bending the malleable projection under the pin-hole to serve as a stop. By preference, also, the malleable projection is bent in'such a way that its end will not extend beneath all portions of the pin-hole, but will leave sufiicient room for the removal of damaged or broken pins by means of a rod or tool pressing against the lower end of the pin.
Reference is now had to the drawings which illustrate my invention, and in which 1 Figure 1 is a side elevation of a malleable draw-head with the projection shown in place thereon, but not yet bent to position to serve as a stop-block. Fig. 1 also illustrates the operation of driving a drift through the pin-holes. Fig. 2 is an elevation of the drawhead, showing a convenient way of bending the projection so as to serve as a stop-block. Fig. 3 is a side elevation of the draw-head, showing the pivot-pininposition therein; and gigd l is a similar front elevation of the drawea k A indicates the draw-head, which is cast of malleable metal and provided with the integral projection D, extending from the bottom plf 1the draw-head adjacent to the lower pin- B B are the pivot-lugs of the draw-head, in which are formed the pivot pin-holes C C. These holes usually re uire clearing out, and the clearing is accomp ished by means of a drift, such as is indicated at E in Fig. 1, and it will be seen in this view that the projection D in no wise interferes with the operation of driving the drift through the pin-hole.
Fig. 2 shows the manner in which the projection D is conveniently bent to proper form to serve as a stop-block. anvil or die F is placed beneath the projection D and the projection then bent over this die, as shown in Fig. 2, the shape and size of the rejection D and die F being such, preferab y, that the end D of the projection, while it extends beneath, does not entirely cover the pin-hole C, and it will be clear from Figs. 3 and 4, which show the pivot-pin G in position, that this method of construction enables a tool to be readily placed against the end of the pivot-pin to drive it upward through the pin-holes.
In the construction shown in Figs. 3 and 4 the pin G is represented as having a head G, which normally rests upon the top of the lock B, the pin being of such length that its lower end Gr does not rest upon the stop-block D D. In case of a breakage of the pin the lower end will drop down and rest upon the end D of the stop-block, the stop-block preventing it from becoming lost, while the position of the pin will indicate to an inspector that it is broken.
G indicates a cotter, which the construction illustrated makes it feasible to insert in the lower end of the pin to prevent its creepin upward.
aving now described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. The method of manufacturing drawheads for railroad-couplers which consists in casting the head of malleable metal and with an integral projecting tongue D, extending from the casting adjacent to the lower pivot pin-hole, then perfecting the pin-holes by forcing a tool through them, and then bend A properly-formed" ing said tongue so that its ends will extend blank adjacent to the lower hole, said probeneath the lower pinhole.
jection being adapted to be bent laterally be- 2. The herein-described blank for n1anuneath the hole and form a stop for the pin. facturing draw-heads for railroad-couplers, l
5 consisting of the casting A of malleable metal I Witnesses:
