DERAILING GUARD.
Application filed April 23, 1921.
To all whom it may concern:
Be it known that FRANK ZEIs, a citizen of France, residing at Trenton, in the county of Mercer and State of New Jersey, have invented new and useful Improvements in Derailing Guards, of which the following is a specification.
The object of the invention is to provide simple and efiicient means for preventing the accidental derailing of cars and similar vehicles which are constructed and designed to traverse tracks consisting of rails such as are used in connection with railway traffic, and in that connection to provide a means for the purpose indicated which may readily be applied as a supplement of the standard railway equipment under conditions which avoid interference with those features of the standard equipment which have been approved and are in common use; and with this object in view the invention consists in v a construction and combination of parts of which a preferred embodiment is shown in the accompanying, drawings, wherein:
Figure 1 is a side view of a truck equipped with guards constructed in accordance with the invention.
Figure 2 is a plan view of the same.
Figure 3 is an end view showing one of the guard attachments in section.
Figure 4c is a detail view of the guard foot to show a preferred form thereof.
The guard attachment consists essentially of a hanger 10 adapted to be supported by the bottom bar 11 of a truck of approved form as indicated in the drawing and suit ably braced as indicated at 12 to resist forward and rearward strains, and a follower 13 mounted for vertical reciprocable movement in the hanger and provided with a foot 14 extending inwardly under the head 15 of the track rail beneath the tread 16 of the vehicle wheel, said rail head preferably being provided with an outwardly directed extension 17 serving as an overhang beneath which the foot travels in the progress of the vehicle in readiness to engage the under surface of the overhang in the event of any tendency of the track to rise from the rails.
In practice it is preferred to cushion the follower by which the foot is carried as by employing a spring 18 interposed between an outwardly extending ear 19 on the follower and a corresponding ear 20 on the hanger, so that in the event of a slight upward movement of the wheels indicating a tendency to Specification of Letters Patent.
Patented July 4, 1922. Serial No. 463,753.
leave the track rails a yielding resistance within certain limits will be offered by the root without interposing a serious obstacle to the forward progress of the vehicle and therefore without involving the risk of breaking or unnecessarily straining the parts or the equipment. Owing to the fact, however, that the yielding quality of the foot is limited, the upward movement of the wheels sufliciently to effect thederailing thereof is prevented, and the frictional contact of the operating shoes with the rail will have a braking or retarding influence upon the progress of the vehicle.
The vertically disposed stem 21 ing from the body portion of the and directly carrying the foot 14. together with the upper and end surfaces of the foot are rounded at the edges or corners to minimize the tendency to catch or objectionably engage any slight projections, irregularities or roughnesses on the surface of the rail.
As a further means of minimizing frictional resistence in the event of contact of the foot with the flange of the rail the shank portion 14 thereof, which in common with the horizontal portion of the foot is provided with rounded corners, is fitted with vertical anti-friction rollers 21 stepped at their lower ends in sockets 22 in the horizontal portion of the foot. embedded for a portion of their depths in the surface of the web 1 1 and fitted at their upper ends in sockets 23 in a overhanging ledge 24,-displacement upwardly of said rollers being prevented by screw plugs 25 fitted in the sockets 23.
Having described the invention what is claimed as new and useful is:
1. A derailing guard for vehicle trucks, having a hanger for attachment to the bottom bar of a truck frame, a follower yieldingly supported for vertical movement in the hanger and provided with a rail head engaging element having anti-friction rollers for contact with the edge of the rail head.
2. A derailing guard having a hanger for attachment to the bottom bar of a truck frame and a spring supported follower mounted for vertical movement in the hanger and provided with a depending inwardly directed foot for terminal arrangement beneath the outer side of a rail head, the shank portion of said foot being fitted with vertical anti-friction rollers for contact with the edge of the rail head.
3. A derailing guard having a hanger for dependfollower attachment to the bottom bar of a truck frame and a spring supported follower mounted for vertical movement in the hanger and provided with a depending inwardly directed foot for terminal arrangement beneath the outer side of a rail head, the shank portion of said foot being fitted with vertical anti-friction rollers for contact with the edge of the rail head; said 10 rollers being stepped at their lower and upper ends respectively in sockets formed in FRANK ZEIS.
