SAFETY APPLIAN FOR RAILWAY-(JARS.

Specification of Letters Patent. Patented April 6, 1909.

Application filed June 11, 1998. Serial No. $7,864.

To all whom it may concern.

Be it known that l, ltonsn'r Barman, citizen of the United States, and a resident of Spanish Ranch, in the county of Plumas and State of California, have invented a new and useful Improvement in Safety Appliances for Railway-Cars, of which the following is a full, clear, and exact description.

T he purpose of the invention is to provide a simple and reliable safety appliance for railwa 7 cars, or trains of cars, that will act to effectually prevent the cars leaving the track, particularly at abrupt curves, and will also serve to prevent the flanges of the car wheels from having undue frictional engagement with the rails.

It is also a purpose of the invention to provide an appliance of the character described constructed in two sections, one section being a fixture beneath a car and the other a fixture between the rails of the tracks.

The invention consists in the novel construction and combination of the several parts as will be hereinafter fully set forth and pointed out in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of a car truck having the improvement applied; Fig. 2 is a side view of the car truck and attached improvement, and a longitudinal section hrough a portion of the roadbed, illustrating the mannor in which the section between the rails is anchored; and Fig. 3 is a vertical transverse section taken practically on the line 3-3 of Fig. 1.

A represents the frame of a car truck, which frame is provided with downwardly extending pedestals 12 in which the boxes 11 for the axles have sliding movement, the said axles being provided with the usual flanged wheels 13. B represents the trusses that are located beneath the side members of the frame and extend from a forward to a rearward box 11, as is illustrated in Fig. 2, and springs 14 of the coiled type rest upon the trusses B and have bearing a ainst the.

under faces of the sites of the truck. The usual plate extenos from one truss to the other, as is shown in Fig. 3, and above this plate a block 16 is located through which king bolt is passed, and longitudinal springs 17 are located between the plate and the said block 16. nll of th foregoing construction is of the ordi'any type.

A stringer Q is located centrally between the rails 18 of the track, extending longitudinally thereof, and the said stringer C is employed as a guide for the car passing over the rack, the application being made in a manner to be hereinafter described. 'l he stringer C which is continuous, may be made of metal, or it may be made from wood; in the latter event, however, it is provided with metal plates at its sides so that the body of the stringer will not become quiclrl worn in service. "lhe stringer C is supported above the roadbed and rests upon the ties c, as is shown in Fig. 2, and it is held in position by means of anchoring devices C, which devices are ouried in the ground for the major portion of their length and. are located at desired intervals apart.

' 1 f? r, Ear-n anchoring device e comprises two 5 id 20, that diverge at their members, 19

and the 0 members it and 20 cl an ovver ends an l extend dmvnwaru, 1w cnoriz device are brought together at their upper ends and are provided with a suitable socket at that point to receive the lower edge portion of the stringer C, as is illustrated in Fig. 3, the stringer being secured to the anchoring devices by means of bolts 22, or their equivalents, as is also shown in Fig. 3. Only the upper end portion of an anchoring device extends above the surface of the roadbed, as is sh wn in Fig. 3, and in order that these anchoring devices (1" shall not work loose, plates 21 are secured at their lower end portions, that extend beyond the side faces and. the longitudinal edges of the said members, as is also shown in Fig.

The car truck is provided with auxiliary trusses l) located below the main trusses B, but the auxiliar trusses D extend longitu dinally oi the truck, one at each side of its center, so that the truck passes over the rails the stringer C will extend up between the auxiliary trusses D, as is shown in Figs. 1 and 2. These auxiliar trusses D are supfroin. the axles 1G by suitable arms 22", or the equivale .ls thereof. At the central portion of each auxiliary truss D, a substantially oval bl cl; 23 is secu ed, extending longitudinally of said auxilia v trusses, as is particularly illustrated in l l, and these blocks 23 are preferably connected at their upper faces by a plate 24 and around each Cir block 23 an endless chain 25 is located, the said chain being provided with a series of friction rollers 26, and as the truck passes along the track the friction rollers at the inner stretches of the endless chain 25 engage with the stringer or guard rail C, and hold the truck in proper position on the track as e'll'ectually when rounding an abrupt curve as when traveling upon a straight stretch of track, and since these guide devices hold the truck in certain relation to the track, said guide devices prevent the flanges of the wheels of the truck from having undue bearing against the rails.

This device is exceedingly simple and is economic and readily applicable to any type of car, being particularly applicable to the trucks used upon ore carrying cars.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent,-

In safety appliances for railway :ars, the combination with a fixed stringer adapted to be located between the rails of a track, of guide devices carried by the truck of a car engaging with opposite sides of the stringer said devices consisting of endless chains provided at spaced intervals with rollers for (211- l gaging the sides of the stringer.

2. in a safety appliance for railway car the combination with a stringer adapted to be located between the rails of a track, of a car truck and endless chain belts adapted to rotate thereon and arranged for engagement with opposite sides of the stringer.

3. In safety appliances for railway cars, the combination with a stringer located fixedly between the rails of a track, and means for securing the stringer in place, of a car 1 truck, trusses carried thereby, one at each i side of its center, guide blocks located on said trusses, endless chain belts adapted to travel around said blocks, and friction rollers carried by the belts adapted for engagement with the opposite side faces of the stringer.

5. In safety appliances for railway cars, the combination with a stringer, an angular anchoring device therefor, the stringer being located parallel with and between the rails of the track, and offsets at the lower ends of the members of the said anchoring devices, of a car truck, trusses supported beneath the said truck, longitudinal and opposing guide blocks carried by the said trusses, endless chain belts mounted to travel around the guide blocks, and friction rollers at the inner stretches of the belts, being adapted for engagement with the opposing faces of the stringer.

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