INTERCHANGEABLE AND REVERSIBLE BRAKE- 'SHOE HEAD- SPEGIFIGATION forming part of Letters Patent No. 7 191,854, dated June 6,1905.

Application filed April '7, 1903. Renewed January 23, 1905. Serial Nil-242,300.

To all whom it may concern.-

Be it known thatI, EDWARD L. ADRnoN, J r. a citizen of the United States, residing at St. Louis, State of Missouri, have inventedcertain new and useful Improvements in Interchangeable and Reversible Brake-Shoe Heads, of which the following is aspecification, containing a full, clear, and exact description,

' reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in interchangeable and reversible ,brakeshoe heads; and it consists of the novel construction, combination, and arrangement of parts hereinafter shown, described, and claimed.

The object of my invention is to construct a brake-shoe head to which is adapted to be applied to any of the well-known types of brake-shoes now on the market. The prevailing types of brake-shoes now on the market are commercially known as the American Brake Companys type of shoe and the Christy type of shoe.

To show the utility of my invention in a commercial sense, it is only necessary to state that, for instance, if a railroad has a brakeshoe head especially constructed to take one of the above types of brake-shoes it would not be possible to use with said brake-shoe head the other type of brake-shoe.

The object of my invention is really to make a brake-shoe head to which any of the wellknown commercial types of brake-shoes may be applied.

In the drawings, Figure 1 is a side elevation, with parts broken away, of my improved brake-shoe'head. Fig. 2 is a top plan view. Fig. 3 is a perspective view of what is commercially known as the American Brake Companys type of brake-shoe. Fig. 4 is a perspective view of what is commercially known as the Christy type of brake-shoe. Fig. 5 isa perspective View of amodified form of what is commercially known as the Christy type of brake-shoe.

Heretofore brake-shoe heads have been constructed with a central opening to receive the central connecting-lug of the brake-shoe, as illustrated in Figs. 4 and 5. Also the brakeshoe head, as has heretofore been manufactured, provided with one aperture or hole in one end to receive the type of brake-shoe illustrated in Fig. 3 is old; but the idea of making a brake-head with a central aperture to receive a brake-shoe provided with a central connecting-lug and also to have the same brake-shoe head provided withan additional aperture in its end or in both of its endsto receive a type of brake-shoe provided with a hole in its terminal portion is new, so far as I am informed, and constructing a brake-shoe head with a central aperture and with a hole in each'of its ends to make the same reversible is also new.

Referring to the drawings, 1 indicates my brake-shoe head, which is provided in its central portion with a hole 2 and is provided at its end portions with holes 3 and 4:.

5 indicates what is commercially known as the Christy type of brakeshoe. Said brake-shoe is provided at'its central portion with an integral lug 6, and said lug 6 is pro- :vided with a transverse hole or opening 7.

Said brake-s'hoeis applied to the brake-shoe head 1 bymeans of a locking-pin 8.

9 indicates what is commercially known as the American Brake Companys type of brake-shoe. Said brake-shoe 9 is provided with a hole 10, and when it is desired to apply said brake-shoe to my brake-shoe head 1 it isonly necessary to use a brake-shoe key-bolt and pass the same through the opening 10 and either of the openings 3 and 4, formed in the brake-shoe head 1. w

My brake-shoe head 1 is also provided with cut-away portions 11, the object of these cutaway portions '11 being to permit my brakeshoe head to receive a modified type of what is commercially known as the Christy type of brake-shoe, which type is illustrated in Fig.- 5and which is indicated by 12. The modified form of what is known as the Christy type of brake-shoe has'the'usual integral connecting-lug 6 and is also provided at its end portions with lugs 13, which are adapted to be located in tlie cut-away portions 11 of my brake-shoe hea It will be seen from the foregoing description that by constructing a brake-shoe head with a central aperture and with an aperture or hole at each end and with the cut-away portions 11 1 have constructed or devised a brakeshoe head which is reversible and which is adapted to receive the commercial types of brake-shoes now on the market. In other words, if a railway company is provided with my brake-shoe heads and they desire to change their type of brake-shoes they may still retain their brake-shoe heads, to which may be fittecl any of the brake-shoes now on the market.

Having fully described my invention, what I claim as new, and desire to have secured to me by the grant of Letters Patent, is

1. An interchangeable brake-shoe head provided with a-central opening adapted to receive the fastening-lug of a brake-shoe and an openshoe and an opening at each end adapted to receive a brake-shoe key-bolt, substantially as specified.

3. An interchangeable and reversible brakeshoe head provided with a central opening 2 adapted to receive the fastening-lug of a brakeshoe and openings 3 and 4 formed in its end portions adapted to receive a brake-shoe keybolt, and cut-away portions 11, substantially as specified.

In testimony whereof I have signed my name tothis specification in presence of two subscribing witnesses.
