.D. D. MARSHALL WHEEL RETAINING BRAKE Filed Dec. 13 1923.

eti
siren er DREDSON D. MARSHALL, GIF BUFFALO, 'NEW' YORK.
wnanL-nnrnrurne Bienne.
application filed December To all ywhom t may concern.'
Be it known that DREDsoN D. MARSHALL, :i citizen of the United States, residing at hihalc, in the county of Erie and State ot N ew vork, has invented new and useful Imf provements in Wheel-Retaining Brakes, of which the following is a specification.
lt is the purpose oi the present invention to provide, in wheel retaining brakes, a construction for preventing derailment, at least entire derailment. `of railway car and locomotive wheels. rihe present apparatus is applicable between the wheels of each truck ci a railway `car and when used on a loco# motive itis positioned to the rear of each wheel.
Another purpose is to provide a device of this kind including a support suitably carried by the truck frame, with yieldably mounted shoes adapted to engage or catch upon the track rail and thereby guard against derailment of the wheels.
lit is to be understood that the particulars herein given are in no way limitative and that, while still keeping within the scope of the invention, any desired modiiications of detail and desired proportions may be made in the apparatus according to the circumstances.
rlhe invention comprises further features and combinations of parts to be hereinafter set forth, shown in the drawings and claimed.
ln the drawings: f
Figure 1 is a view in side elevation of a portion' of a railway car truck, showing the improved wheel retaining or guarding means applied in accordance with the invention.
Figure 2 is a longitudinal sectional view through the retaining or guarding means.
Figure 3 is a sectional view on line 3--3 of Figure 2.
Figure 4 is a detail perspective view of one of the shoes or guarding means.
Referring to the drawings, 1 designate blocks constructed of any suitable material, preferably metal, and which may be suitably supported on a railway car truck, as at 2"-, whereby the wheel retaining or guarding means or shoes may be supported in position, one on each side of the rail.
Illhc under face of the block has depressed seats 2 which have countersinks 3, and d denote shoes" or wheel retaining members. 'llhe shoes are mounted for veris, ieee. serial ivo. ceases.
tical movements in the depressed seats 2 and have their forward and rear edges provided with bevels which are aligned with the bevels 6 which are formed at the lower orward and rear portions of the blocks. The shoes are centrally hollowed or cut away, as shown at 7. to lighten the shoes which are disposed upon opposite vsides of the track rail for the purpose of engaging the rail in case certain oi the wheels derail, thereby preventing entire derailnient of all the wheels.
The bevels 5 and 6, especially the former, act to permit the shoes to ride over any obstructions, such as frogs, switch-points, crossing rails and the 1iike. Obviously, the shoes will yield owing to their particular mounting in the blocks. The shoes have threaded sockets 8 in which a plurality of rods -9 are secured. To insure preventing the rods from turning, the surfaces of the rods and the shoes immediately where the rods rise from the shoes are gouged, as at 10. In this manner the rods are held rigid and are prevented from detachment. rlhe rods pass through the countersinks 3 and penetrate through the blocks and are thus capable of sliding movements through the blocks, in case the shoes are depressed upwardly due to contact with frogs, switchpoints or similar obstructions.
Relatively heavy coil springs 11 are in surrounding relation to the rods 9 and are interposed between the bottoms of the countersinks and the upper races or the shoes for the purpose of tensioning the shoes and holding them in such positions in readiness to engage with the track rails Jfor the purpose of preventing entire derailment of all the wheels. Suitable nuts 12 are threaded upon "the upper ends of the rods to prevent downward movement thereof and whereby the shoes may be adjusted relatively `to the rails. Suitable cctter pins or keys 13 are engaged through the upper extremities of the rods to prevent detachment of the nuts.
rlhe blocks carried by each truck are connected by means of a connect-ing bar or brace 14; to further insure rigidity and to hold the blocks in position.
The invention having been set forth, what is claimed is:
l. A wheel guard and retainer including a supporting member mounted upon a railway car truckl between the wheels, and
yieldably mounted elements carried bythe4 'iii Vzo
member and disposed upon opposite sides or the track rail, thereby preventing derailment of all the wheels of the car in oase certain of the wheels derail.
2. In a device as set forth, the combination with a railway oar truck, of a member carried by the truck between the wheels thereo and provided upon its under surface with depressed seats, and shoes movable slidably in said space and disposed upon opposite sides of the track rail, whereby they may engage with the rail and guard against derailment of all the wheels.
3. In a device as set forth, the combination with a railway car truck, of members depending from opposite sides of the truck between the wheels and provided upon their under surfaces with depressed seats, means connecting the members to insure rigidity therebetween, and a pair of shoes yieldably mounted in the seats of each member anddisposed upon opposite sides of the track rail to guard against derailment of all the wheels, forward and rear lower portions of the shoes and the members being correspondingly beveled to permit the shoes to ride over obstructions.
nfs-.eener 4t. In a device as set forth, the combination with a railway car truck, of members carried by and depending from opposite sides of the truck between the wheels and provided upon their under surfaces with depressed seats having countersinks, means Connecting the members to insure rigidity, rods passing through the countersinks and penetrating the upper wall of each member, a pair of shoes mounted in the depressed seats of each memberand positioned upon opposite sides of the track rail to guard against dei-ailment of all the wheels, said shoes being` suspended 'from the rods, springs in surrounding relation to the rods and interposed between the bottoms of the countersinks and the shoes, and means for adjusting the rods to tension the springs, the forward and rear lower portions of the shoes and each member having corresponding bevels whereby the shoes may ride over obstructions, such as switch-points and the like.
In testimony whereof he aixes his signature.
DREDSON D. MARSHALL.
