RICHARD JAMES EDWARDS, OF GALENA, ILLINOIS.

DERAlLMENT-GUARD.

SPECIFICATION forming part of Letters Patent No. 777,189, dated December 13, 1904.

Application filed February 13, 1904. Serial No. 193,443. (No model.)

To all whom it may concern.-

Be it known that I, RICHARD JAMES E1 \VARDS, a resident of Galena, in the countyof Jo Daviess and State of Illinois, have invented certain new and useful Improvements in Derailment'Guards; 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 it appertains to make and use the same.

My invention relates to an improvement in derailment-guards, the object of the invention being to provide improvements of this character adapted for use on any form of truck and which. will be simple in construction and operation, comparatively cheap to manufacture and install, strong and durable in use, and which will absolutely prevent derailment when the wheels leave the track and will prevent the wheels leaving the track should a flange break or for any other cause the wheels tend to move laterally on the track.

With this object in view the invention consists in certain novel features of construction and combinations and arrangements of parts, will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a View in side elevation illustrating my invention. Fig. 2 isa bottom plan View. Fig. 3 is a view in cross-section, and Figs. 4 and 5 illustrate my improvements on a diflerent construction of truck.

1 represents the truck supported on ordinary wheels 2 and having a partition or brace 3 at its center, as shown. Bifurcated brackets 4 are secured on opposite sides of partition 3, and bars or arms 5 are pivotally secured in said brackets by means of belts or pins 6, passed through alined openings in the brackets and bars or arms. On the outer ends of these arms 5 my improved guards 7 are secured and comprise a rectangular frame 8, preferably cast integral, having recesses r openings 9, in which rollers or wheels 10 are mounted and project below frame 8, so as to be adapted to run upon the rail. These wheels are made hollow to hold lubricant-saturated waste to maintain their axles oiled at all times. At the inner bar of frame 8 a de pending tongue or flange 10 is provided and located adjacent to the inner face of the rail that is to say, either against the rail or removed therefrom and in position to engage the rail should the wheels leave the track.

The arms are guided vertically and strengthened against lateral strain by bars 11, having central recesses 12, in which the arms 5 are located and move vertically, and bails 13 are secured across the bottom of the recesses 12 to limit the downward swinging movement of the guards.

In operation the guards 7 rest with their rollers on the rails, and as the arms 5 are pivoted at their inner ends to the truck the guards are not affected by any upward movement of the truck. Hence should the truck tilt from side to side or otherwise the wheels at one side should leave the rails the flange 10 of the guard will engage the rail and prevent sidewise movement of the truck and me vent derailment.

In Figs. 4: and 5 I illustrate my improvements on another form of truck, having a heavy cross-bar 14. With this form of truck a double bracket 15 is secured to the center of bar 14 on its under face and has the guardarms 5 pivotally connected therewith, and the arms are guided vertically and strengthened against lateral strain by means of grooved or recessed brackets 16, secured to the bar 14.

My improvements are adapted for use on any form of truck, whether for passenger or freight cars and regardless of their construction.

A great many slight changes might be made in the general form and arrangement of the parts described without departing from my invention, and hence I would have it understood that I do not restrict myself to the precise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a truck, of an arm pivoted thereto, and a derailment-guard on the free end of said arm and adapted to maintain engagement with the rail at all times.

2. The combination with a truck, of an arm pivoted thereto, and a derailment-guard at the free end of said arm adapted to constantly engage the rail,and having a depending tongue or flange maintained adjacent to the inner face of the rail.

3. The combination with a truck, ofarms pivoted thereto and projecting laterally in opposite directions, and derailment-guards on the outer ends of said arms in constant engagement with the rails.

4. The combination with a truck, of arms pivoted thereto and projecting laterally in opposite directions, derailmentguards on the outer ends of said arms, having rollers resting on the rails, and depending flanges or tongues adjacent to the inner faces of the rails.

5. The combination with a truck, of arms pivoted at their inner ends to the truck and projecting laterally in opposite directions, derailment-guards on the free ends of the arms in constant engagement With the rails, and recessed guides for the arms, located between the ends thereof.

6. The combination with a truck, of an arm pivotally secured thereto, and a guard on the outer end of said arm, comprising a frame, in which rollers are mounted to run on the rail, and having a dependent tongue or flange at its inner edge.

7. The combination with a truck, of a derailment-guard comprising two members having unobstructed pivotal connection at their inner ends with the truck and projecting laterally from their pivotal support, each of said members having a part to ride on the tread of the rail and a depending part to be disposed alolngside the inner face of the head of the rar In testimony whereof I have signed this specification in the presence of tWo subscribing Witnesses.

RICHARD JAMES EDWARDS.
