LILLIAN E. ROBINSON, OF NEW YORK, N. Y.
BRAKE-SHOE.
SPECIFICATION forming part of Letters Patent N 0. 790,754, dated May 23, 1905.
Application filed December 3, 1904. Serial No. 235,299.
To (tZZ whom it may concern.-
Be it known that I, LILLIAN E. RoBINsoN, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Brake-Shoes, of which the following is a specification.
This invention relates to improvements in railway brake-shoes, and especially to a brakeshoe which is adapted to have attached to the front or gripping portion thereof a back or rear portion of a partially-worn brake-shoe, so that partially worn shoes may be entirely used up by applying them to new brakeshoes, thus saving a waste and utilizing worn portions of brake-shoes which are at the present time rendered unfit for use and are discarded.
To this end it consists of a brake-shoe of ordinary construction having an attachinglug on the back side thereof, through which runs an opening for receiving the attachingpin on the brake-head and for other purposes, which will hereinafter be more fully set forth. The gripping-surface of the shoe is provided with a socket to allow the insertion of the lug of a partially-worn brake-shoe therein. The socket is provided also with an enlarged inner end and with a groove or grooves to admit the insertion of a flexible fastening-pin.
[n the drawings herewith accompanying and forming a part of this application, Figure 1 is a sectional view of a brake-shoe, showing the flexible pin and partially-worn shoe in process of insertion. Fig. 2 is a sectional view of the brake-shoe with the partially-worn shoe in place. Fig. 3 is a detail of a form of flexible pin. Figs. 4 and 5 are sectional views showing a slight modification in the flexible pin, and Fig. 6 is a plan view of the gripping-face.
In said drawings, A represents a brake-shoe of ordinary description provided with guiding or looking lugs B on the back thereof. Also on the back thereof is an attaching-lug O, provided with an opening D. The gripping-surface of said brake-shoe is provided with a socket E, extending partially into said shoe. Said socket is provided also with an interior recess or enlarged inner end F and groove G, the purpose of this latter being to allow the insertion of a flexible pin H within the opening and of the former to cause the pin when the lug of a partially-worn brakeshoe is inserted in the opening to be bent into a holding position. The pin may be of any desired shape, it being necessary only that the same be constructed of such material and of such form as to allow it to be bent so that the free ends of the pin will enter the opening in the attaching-lug of the partially-worn brake-shoe and fit closely in the enlarged inner end of the socket, the enlarged inner end being for the purpose of receiving the extended portion of the flexible pin when the lug of a partially-worn brake-shoe is inserted within the socket in the gripping-face, so that when the said worn brake-shoe is driven home the extended end of the pin will rest in the enlarged end of the socket and hold the inserted shoe in position. When a brakeshoe becomes so worn that it will not perform its work satisfactorily, the same is removed from the brake-head and a new brakeshoe attached thereto. A flexible pin is then placed on the lug of partially-worn shoe or bent so as to enter the opening in the lug, and the lug is then driven into the socket. The pressure caused by driving the lug into the opening upon the flexible pin causes the same to be straightened, and consequently to lit into the enlarged inner end of the socket and [ill the same, thereby firmly holding the partially-worn brake-shoe in position.
The advantages of this invention are that it provides means for using up partially-worn shoes, for by the insertion of a partially-worn brake-shoe in new shoes the partially-worn shoes may be used up instead of being thrown on the scrap heap, as is the custom at present.
Having described my invention and its use, what I claim as my invention, and desire to secure by Letters Patent, is
1. A brake-shoe having an attaching-lug with a lateral opening running therethrough, a socket in the gripping-face of said shoe, said socket having a lateral offset, and a flexible bent pin adapted to be bent into said offset and to take into the opening in the lug of another shoe when it is inserted in said socket.
In testimony whereofIhave signed my name 10 to this specification, in presence of two subscribing Witnesses, this 29th day of November, 1904.
