ARTHUR LIPSCHUTZ, OF ST. LOUIS, MISSOURI.
BRAKE-JAW FOR CAR-BRAKE RODS.
SPECIFICATION forming part of Letters Patent No. 733,853, dated July 14, 1903.
' Application filed January 19,1903. Serial No. 139,625. (No model.)
To all whom it may concern.-
Be it known that I, ARTHUR'LIPSCHUTZ, a citizen of the United States, residing in the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Brake-Jaws for Oar-Brake I jaw to which the brake-rod can be attached in a more secure, convenient, and economical manner than heretofore, as well as in less time and without'requiring the use of special tools.
My invention consists in features of novelty hereinafter fully described, and pointed out in the claims.
Figure I is a perspective view of my brakebeam jaw. Fig. II is a longitudinal vertical section of the jaw, showing the adjacent end of the brake-rod with its extremity turned down in the act of applying the rod to the jaw. Fig. III is a like view showing the extremity of the rod bent around the web of the jaw, which position it assumes when the rod is fully attached to the jaw. Fig. IV is a horizontal section taken on line IV IV, Fig. III.
Referring to the drawings, 1 represents the jaw, that is preferably in the form of a cast ing of either steel or malleable iron. It has a longitudinal opening2, that receives the brake-lever, which Ihave not shown. The inner end of the jaw is provided with the usual opening 3 to receive the bolt that connects the jaw to the brake-lever. At the outer end of the opening 2 the jaw has a vertical wall 4 toreceive any inward thrust of the brake-rod, and beyond this wall is a vertical opening 5 to receive the end of the brake-rod 6. Between the opening- 5 and the end of the jaw is a web 7, that is preferably of less thickness than the jaw, thereby forming a groove 8, in which the brake-rod is embedded when its end has been bent around the web, as shown in Fig. III.
To attach the rod to the jaw it is only necessary to bend its end at right angles to its length and then insert it into the opening 5, as shown in Fig. II, and then by the use of an ordinary hammer to bend the extremity of the rod around the web into the position shown in Fig. III. This attachment of the rod to the jaw can be efiected without heating the former and can be very quickly accomplished without the use of any special tools, which are often not at hand when a brake-rod becomes broken and a new one has to be applied. The work can be quickly and economically accomplished, and when the job is done it is ofa substantial and permanent character, and the rod is held from longitudinal movement with relation to the jaw when the brakes are operated.
The opening or perforation 5 extends vertically through the jaw or in the same direction as the opening 3, so that a central draft or pull of the rod on the jaw is provided for,
and by passing the bent end of the rod through the opening 5 from the top there is no tendencyof the rod to drop away from the jaw while its extremity is being bent around the web or in case of any straightening out of the bent portion of the rod.
I claim as my invention 1. A brake-jaw for car-brake rods, having a perforation or opening at its outer end, through which the brake-rod is adapted to pass,andhavinga web beyond the opening about which the extremity of the rod is adapted to be bent, substantially as set forth.
-2. A brake-jaw for car-brake rods having a perforation in its outer end through which the brake-rod is adapted to pass, a wall forward of said perforation, and a web back of said perforation about which the extremity of the rod is adapted to be bent, substantially as set forth.
3 Abrake-jaw for car-brake rods having 'a perforation or opening at its outer end through which the brake-rod is adapted to be passed, and having a web beyond said-opening of less thickness than the jaw, whereby a groove is formed to receive the rod when the latter is bent around the web, substantially as set forth.
4. A cast brake-j aw for car-brake rods, having an opening to receive the brake-lever, and ing about which the brake-rod is adapted to a perforation at its inner end to receive the be bent, substantially as set forth. connecting-bolt; the outer end of said jaw being formed with an opening extending in the ARTHUR LIPSOHUTZ' same direction as said bolt opening, and In presence ofwhich is adapted to receive the end of the E. S. KNIGHT,
brake-rod and havingzt Web beyond said open- M. P. SMITH.
