Raff-Roansnrn'rnnnvion- To all, whom timely/concern Beit known that I, BENJAMIN. Mom), ing' at Beloit, inthe county of State 10f Wisconsin, have inventedcertain new and usefullmprovements in Rail-road Sa'fety Devices; and I do hereby; declare-the new;

following to be afu-ll,- clear', and exact descriptionof the invention, such as will enable others'skillearin'thearrto which 1t appertains to make and use the same-.5 V

This invention relatesto iniprovenients 1n a railroad safety devieeand has--for one of its objects the provision of a device of this character, whereby cars and the like will be prevented from jumpmg or dlsengagmg from the railroad tracks.

Another object of this invention is the provision of an intermediate or third rail secured to the ties of a road bed or a railroad track and adapted to be engaged by means carried by the trucks of the cars or the like to prevent them from jumping the track and also obviating undue swaying'and rocking of the cars.

A further object of this inventionis'the manufactured and sold at a comparatively low cost. 7

With these and other objectsin view as will become more apparent as the descrlption proceeds, the invention consists-in voertain novel features of construction, combmation and arrangement of parts which Wlll be hereinafter more fully described and claimed. 7 V

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is an end elevation partly in section of a railroad safety device constructed in accordance with my invention,

Fig. 2 is a longitudinal sectional the same,

Fig. 3 is a bottom plan v1ew illustrating the means carried by the trucks for engaging the intermediate or third rail,

Fig. 4 is a-,pla1rview-oftherailroadtrack,

the railroad rails 2. An intermediate or;

third'rai1-3-issecured-totheities 1 between the railroad rails- 22 and are? in the shape of' eye-beams 5 in cross-section,-- including base portions 4, a web portion 5 carrying laterally projecting flanges 6 which are engaged by an attachment carried by the cars which will be hereinafter more fully described.

The numeral 7 indicates a portion of a rail' n y I road car or the like to which isconnected in any desired manner a railroad truck consisting of a supporting beam 8 carrying ateach end journal supporting members 9. journal supporting members 9 have connected to their free ends journals 10 in which are rotatably mounted axles 11. The axles 11 have secured thereon ordinary car wheels 12 for engagement with the railroad The I rails 2. The journals 10 are of the ordinary construction in which lubricant is placed for the purpose of reducing friction.

Downwardly and inwardly extending supporting members 13 are secured to the ournal supportln-g members 9 in close prox imity to the connection of the beam 8 thereto and have secured to their inner ends longitudinally extending roller supporting members 1 1 that are disposed in'close proximity to the third orintermediate rail 3 andupon each side thereof. 'Ball bearin rollers 15 are ournaled upon stub shafts 16.

' carried by each end of the roller supporting members 14 and engage the-under faces of the flanges 6 upon the third or intermediate rail 3. 1

Vertically disposed arms 17 are carried by the stub shafts 16 and secured to jour-.t nals 18 mounted on the axles 11 intermediate their ends. The arms 17 are arranged in pairs and connected by bolts 19 to which are secured braces 20. The braces 20 incline 8 as clearly illustrated in Fig. 3.

From the foregoing description taken in connection with the accompanying draw-.

ings, it will be noted when a car 7 is supplied with my improvedinvention, the same will be prevented from swaying or rocking and also will prevent the wheels from jump ing or disengaging the rails of the railroad track. V

The third or intermediate rail 3 is supported and braced to the railroadrails by hangers 21 and are only preferably applied to mainrailroad tracks or where the carsor the like travel at a rapid speed to prevent them from jumping the tracks and rocking or rolling thereon. The intermediate or third rail 3 at its ends has its flanges 6 pointed or reduced as illustrated at 22 so that the rollers 15 may engage and disengage when approaching or leaving the point of the track where the third or intermediate rail is used.

While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.

Having thus described my invention, what 1 claim is:

A railroad safety device including a truck having a beam with an axle spaced on each side thereof carrying wheels, journals on said aXles,substantially U-shaped members having their bight portions secured to the under faces of thejournals and having their arms depending downwardly therefrom, a stub shaft secured to the lower end of each arm of the U-shaped members, rollers journaled to the stub shafts and arranged in pairs to engage under the flange of a guard or safety rail, braces connecting the arms to the beam and longitudinally extending rods connecting the stub axles in pairs.

In testimony whereof I afiix my signature in presence of two witnesses.

BENJAMIN ROLLA ND HAMMOND.
