RALXUAY SAFETY DEVICE.

Application filed March 6, 1925.

This invention relates to a s fety device for locomotives, or the like, particularly of the type indicating. the spreading of the tracks upon Awhich the locomotives run.

The invention has for an object, the provision ot' a simple, inexpensive device which will either give warning to the engineer of the locomotive that the tracks are spreading, or else apply the braking mechanism and stop the train.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

Referring to the drawing forming a material part of this disclosure 1- Fig. 1 shows a side elevational view of a locomotive having the invention applied thereto.

Fig. 2 shows a fragmentary front elevational view of the invention device, per se.

Fig. 3 shows a fragmentary view looking in the direction of the arrows 3 8 in Fig. 2.

Fig. 4 shows a fragmentary partly sectional view taken on the line 4 4 of Fig.

Fig. 5 shows a top elevational view of the invention device.

Fig. (5 shows a fragmentary front View, some parts being shown in section, of a modification of this invention.

The reference numeral indicates generallya locomotive, having one of its wheels, namely as indicated at 11, rotatably mounted on a shaft 12, depending from a lower support 18, pivotally connected to a main support 14, fixed to the locomotive body. A pressure spring has one end Xed to the main support 14, and the other end bearing against the lower support, to force the wheel 11 outwards so that its flange 11 always bears against the track 16, as customarily used in railroading, which track rests on ties 17. It is readily seen that, should the rails 1G spread, the wheel 11, and the support 18 will be caused to move outwards due to the action of spring 15.

To either notify the engineer of the locomotive of the danger, or else to apply the brakes, a transmitting member 18 guided within a tube 19, communicating from the engincers cabin 20, to a point within the main support 14, which is constructed partly hollow therefor, and is further provided Serial No. 92,798.

with a longitudinal slot 14a, through which projects a rack 21, fastened at one end to the member 18, and meshing with a pinion 22, rotatably mounted on a support 23, depending from the main support 14. Coaxially with said pinion 22, a ratchet wheel 24 is mounted, engaged by a ratchet 25, depending from the lower support 18, and a spring 2G engages between the ratchet wheel, and ratchet so as'to maintain the ratchet in engagement with the same tooth of the ratchet wheel, therefore an outward movement of the wheel 11, causes the ratchet to turn thev pinion, which in turn moves the rack, thus operating the member 18, while upon the movement of the wheel 11 to its original position the operation is reversed, since the spring 26 causes the ratchet wheel to turn back to follow the ratchet. The function of the various ratchet teeth being to allow adjustment of the position of member 18.

The modification illustrated in Fig. 6 shows a lever 27, pivoted at 28 to the main support 14, and having its lower end faste ened to the lower support 18, while its upper end, has an adjustable catch 29, holding member 18 against the action of a tension spring 30. Should the wheel 11 move outwards a predetermined distance adjusted by the adjustable catch 29, it will cause the catch 29 to release the member 18, which will thereupon be snapped downward by spring 30. A door 81 hinged at its lower end, as at 32 to a stationary member of the locomotive body has a locking device at its upper end. Access to reset member 18 may be had thru said door 31.

Vilhiie I have illustrated and described my invention with some degree of particularity, I realize that in practice various alterations therein may be made. I therefore reserve the right and privilege of changing the form of the details of construction or otherwise altering the arrangement of the correlated parts without departing from the spirit or the scope of the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is 1. A safety device for locomotives, or the like, comprising a main support having pivotally mounted thereon a lower support, provided with a shaft rotatably supporting a flanged wheel, bearing against one rail by the action of a spring fixed at one end to the said main support, and having its other end bearing against said lower support, which is provided with a ratchet, engaging a tooth of a ratchet Wheel, by the retaining action of a spring, said ratchet Wheel being mounted on a rotatably supported shaft, carrying a pinion, meshing with a rack, fastened to a transmitting inembei.

2. A safety device for locomotives, or the like, comprising a main support, fixed to the locomotive proper, and, having pivotally mounted thereon a lower support, provided with a shaft rotatably supporting a flanged Wheel, bearing against one rail by the action of a spring bearing against said lower support, which is provided with a ratchet, engaging a tooth of a ratchet wheel, by the retaining action of a spring, said ratchet ivlieel being mounted on a rotatably supported shaft, carrying a pinion, meshing With a rack, fastened to a transmitting member.

3. A safety device for locomotives, or the like, comprising a. main support having pivotally mounted thereon a loiver suppoit, provided with a shaft rotatably supporting a flanged Wheel, bearing against one rail by the action of a spring fixed at one end to the said main support, and having its other end bearing against said lower support, which is provided With a ratchet, engaging a tooth of a ratchet Wheel, by the retaining action of a spring, fastened at one end to said ratchet, and at the other to said ratchet Wheel, said' Aratchet Wheel being mounted on a rotatably `supported shaft, carrying a pinion, meshing With a rack, fastened to a transmitting member.

et. A safety device for locomotives, or the like, comprising a main support having pivotally mounted thereon a lovver support, provided with a shaft rotatably support-ing a flanged wheel, bearing against one rail by the action of a spring fixed at one end to the said main support, and having its other 'end bearing against said lower support, which is provided vith a ratchet, engaging a tooth of a ratchet Wheel, by the retaining action of a spring, said ratchet Wheel being mounted on a shaft, rotatably mounted by means of a support, depending from said main support, and carrying a pinion, inesliing with a rack, fastened to a transmitting member.

A safety device for locomotives, or the like, coniprising a main support having pivotally mounted thereon a loiver support, provided with a shaft rotatably supporting a flanged wheel, bearing against one rail by the action of a spring fixed at one end to the said main support, and having its other end bearing against said loiver support, Which is provided with a ratchet, engaging a tooth of a ratchet ,vheel, by the retaining action of a spring, said ratchet Wheel being mounted on a rotatably supported shaft, carrying av pinion, meshing with a. rack, fastened to transmitting member, housed in a hollenY portion of said main support, and extending through a tube to the control cabin of the locomotive.

G. A safety device for locomotives, or the like, comprising a main support having pivotally mounted thereonla lower support, provided. with a shaft rotatably supporting` a flanged Wheel, bearing against yone rail by the action of a spring iixed at one endL to the said main support, and having its other end bearing against said lower support, which 'is provided With a ratchet, engaging a tooth of a ratchet Wheel, by the retaining action of a spring, said ratchet Wheel being mounted on a rotatably supported shaft, carrying a pinion, ,meshing with a rack, fastened to a transmitting member, housed iii a hollow portion of said main support, and extending through a tube to the control cabin of the locomotive, said rack projecting thru a longitudinal slot in said main4 support.

ln testimony whereof I have affixed my signature.
