SAMUEL HATT, OF MONTREAL, QUEBEC, CANADA, ASSIGNOR TO GEORGE. SANDERSON, OF SAME PLACE.
BRAKE-SHOE.
SPECIFICATION forming part of Letters Patent No. 399,665, dated March 19, 1889.
Application filed July 26, 1888. Serial No. 281,106. (No model.)
To aZZ whom it may concern.-
Be it known that I, SAMUEL HATT, gentleman, of the city of Montreal, in the district of Montreal, Province of Quebec, Canada, have invented new and useful Improvements in Brake-Shoes; and I do hereby declare that the following is a full, clear, and exact description of the same.
My invention relates to an improved construction of brake-shoe, chiefly used for the wheels of railway-cars, formed partly of hard orchilled metal and partly of soft metal, the soft portion giving the shoe a good hold upon the wheel and the hard port-ion causing the shoe to wear much longer than if of soft metal throughout. a
The object of my invention is to form a continuous core of hard metal within the body of the shoe. This enables the core to be made of a superior quality of metal, while the body may be made of ordinary or inferior metal.
In the drawings hereunto annexed similar letters of reference indicate like parts.
Figure lis a side elevation of a brake-shoe and also of a cover used in casting the chilled or hard core thereof. Fig. 2 is a view of the face of the brake-shoe shown in Fig. 1. Fig. 3 is a modification of the configuration of the chilled or hard core. Fig. 4c is a cross-secti0n taken on line 00, Fig. 2, showing also the cover I) in place therewith. Fig. 5 is a cross-section taken on line 12 Fig. 2.
A is the body of the shoe, which will be of any desired form, as in ordinary use.
B is the ordinary projection by which the shoe is attached to the head of the brake; or any other desired means maybe used for this purpose.
The body A will be molded and cast in sand (so far) in the ordinary way; but in so molding it it will be provided with a dovetailed recess, F, in which will be cast the chilled or hard core of the shoe. The dovetailed groove F may be of a great variety of configurations. As shown in Fig. 2 it is Very much the form of an X, and as shown in Fig. 3 it is of a serpentine form. From these a general idea will be formed of some of the varieties of configurations which may be used; but it will be understood that whatever the configuration may be the groove will always be dovetailed, as shown at C in Figs. 4 and'5.
D is a cover made to agree with the form of the face of the shoe. This is provided with a projection, E, agreeing with the configuration of the groove in the body of the shoe, and so arranged that when the cover D and body of the shoe are placed together, as shown in Fig. 4, the projection E will fill a small portion of the groove F. This may also be said to be indicated by the dotted line 1 in Fig. 1.
After the cover D and body A have been arranged and secured together, as described, suitable vmetal for chilling or hardening is poured into the groove F through a pourhole, I'I, formed in any desired or suitable position in the body of the shoe,which, being cold at that time, will cause the chilling or hardening of the metal. Thus a shoe is formed having a soft body and a hard core, I.
The object of providing the projection E to the cover D is, that the brake-shoe, when finished, will have the core I with its outer surface sunk below the bearing-surface of the body A, and thus enable the shoe to wear down to the shape of the car-wheel before the wheel comes in contact with the hard core I.
hat I claim, and wish to secure, is as follows:
The combination of the body A, castwith a dovetailed groove, F, with a core of chilled metal, I, cast within said groove F, the whole substantially as described.
SAMUEL HATT.
