Iontgomery,

. and State of Alabama, have invented certain new and useful Improvements in Safety Appliances for Railroad-Cars; and I do hereby declare the following to be a full, clear, and

, exact description of the invention, such as will enable others skilled in the art to which 1t la/Appertains-to make and use the same.

construction and is a side view s truck with my view of the'same. Fig. 3isa Itig. 2 is an end side elevation, partly in section, of acportion of the same on an enlarged scale, an Fig. 4 is a side elevation, partly in section, showing the manner of supporting the inner shoes of each pair.

alrepresents anordinar'y passenger truck having the usual equalizer frame I) and springs c and (1.. Bolted to the front and rear of the equalizer frame are brackets e and f,

' shown in Fi 3.

thc ournal boxes 9 being carried thereby and preferably made integral therewith, as

' hese journal boxes i of an being lettered L, the journal boxes belng prol-covers jl.

are fastened to t e open frame which i ilmlSl'leS a guide for the journal box,

and these bolts pass freely through slots in the correspondingbracket e. ',Each of the brackets c and f is rovided with an extension. On each of t ese extensions is ivotally mounted a shoe m. Forv an or inary form of truck there are eight of these shoes, one mountedjinside and one outside of each wheel. .Th'esc shoes are supported under ordinary conditions by springs n and are-of the type mentioned in my former patent referred to above.

play I W eels. To each of .u carrying one of the inner shoes 1;.

being kept in position connected to pins on for the pur ose of keeping the journal boxes in place if t e axle should break close to the box, as sometimes happens.

p represents auxiliary beams for supporting the inner shoe of each pair. To these beams is bolted the upper semi-circular half of the casing g, the lower parts of said casing being attached to the upper parts by means of bolts r. This casing 9 extends from the inside of one wheel to the inside of-the o posite Wheel, so as to prevent the axle rom dropping if it should break. between the downwardly extending substantially triangular frame 8, which carries at its lowest central point a boss t for the reception of the pin The pin it extends through both of said frames s and carries both of th shaped brace w is casing g and surrounds w aving the inner said pin a, said brace projecting portions y against which faces of the shoes 1; abut, the shoes on said pin a by means of said enlarged portions y and cotter pins 2 passing through the rod or pin a.

aving thus descrlbed my invention, What secure by Letters" I claim as new and desire to Patent of the United States 1s:

1. In a safety appliance for cars and locomotives, the cofnbination'ofa truck having an erjualizer frame, brackets secured to said equa izer frame, each having thereon, a shoe pivotally supported on each of said brackets, and springs normally holding said shoes in a horizontal position, substantially as described.

In'a safety appliance for cars and locomotives, the

the beams p is bolted a a journal box combination of a truck havingasses over one of the e inner shoes 1). A V secured by a bolt to the an equalizer frame, brackets secured to said said brackets having a journal box made integral therewith, guides for said.

journal boxes, said journal boxes and passing over a fixed portion of the truck, shoes, one'of which is pivotally mounted on each of said-brackets, and springs normally holding said shoes in a horizontal position, substantially as descrlbedi a chain attached toeachof I 3. In a safety appliance for cars and loco- I motives the combination of a truck having an equalizer frame, supporting beams carried thereby, downwardly-extending frames supported by said truck, a easing surrounding the car axle bolted to saidbeams, a pin or rod supported by said frames, shoes pivotally I mounted on said pins, and springs normally passing through said frames, a shoe pivotally mounted on said rod near each extremity.

thereof, springs normally holding said shoes in a horizontal position, and a ii-shaped brace attached to said casing and having its ends surrounding said rod, substantially as described.

In testimony whereof, I affix my signature, v

in presence of two Witnesses.
