SWITCH-POINT PROTECTOR.

Application filed September 22, 1926, Seria1 No. 136,941. Renewed November 2,1928. I

The present invention relates to improvements in switch point protecting devices for railway switches or turnouts and consists of features of construction and arrangement designed to produce an improved device adapted to be eflicientin eliminating or reducing wear and damage to switch points and to reduce danger of derailments in switching. A particular Ob ect of the present improvements is to produce a simple structure that may be economically produced and which is designed to operate by engagement with the outer or nonflange side of the car wheel so as to be positioned remote from the wheel flangeway and adapted for installation in advance of the switch point so as to be noninterfering with the switch structure.

Important features of my improved device embody in an integral structure designed to be supported upon a single tiean improved arrangement of the deflect ng flange adapted to effect an inward deflecting movement of the car wheel, in the direction of switching, throughout substantially the full length of the protectormember and to further provide for the required deflecting of the car wheel when passing in the opposite direction for running through. Flo this end the deflecting flange is formed with its inwardly directed wheel engaging surface tapered or angularly disposed for substantially its entire length in a single plane thereby to provide an elongated deflecting surface at a relatively small angle to the tangent adapted for more radual shifting of deflection of the car heelduring the switching operation for the purpose of clearing the extreme end of the switch point. Associated with this improved arrangement of the switching deflecting surface the flange is further of a form to provide for the proper running through of the wheel in the opposite direction and to this end is formed at end portion with its inner surface inclined and of progressively lessened depth of inclination toward the center of the device whereby upon en agement there with of the wheel the latter will be deflected inwardly for clearing the protector member in its passing.

The described and other features and advantages of my present improvements will be more fully understood by reference to the accompanying drawings wherein like refthrust of the car wheel.

erence characters are employed to designate the corresponding parts in the several views.

In the drawings:

In the preferred embodiment of the features of my invention as here illustrated, the switch point protector is shown formed as an integral casting composed-of a head portion 1, a vertical web portion 2 and a base portion 3 and with the head and base portions connected byinclined transverse ribs 44.- for purposes of lateral reinforcement and to resist tilting action. a

The head portion 1, as shown, is formed with a vertical inwardly directed surface. to engagethe side of the rail head and at its lower inner marginal portion with an inwardly extended longitudinal flange or shoulder 6 positioned to engage with the underside or'fishing surface of the rail head 7 of track rail 8. The shoulder 6 accordingly functions to resist tilting of the protector memberunder the influence of the outward Upon its outer side portion the headis formed with an up-o wardly and longitudinally extended deflecting flange 10 positioned to extend above the horizontal plane of the top of the rail to be engaged by the outer or non-flange side of the car wheel for thepurpose of deflecting the wheel in the direction of switching.

In accordance with the present invention,

the deflecting flange 10 is ofan improved form and arrangement having its inwardly directed wheel engaging surface 11 angularly disposed to provide a continuous lateral acting deflecting surface for substan tially the full length of the protector member, said angular surface being arranged to be effective for laterally shifting the car wheel in the direction of switching and in the switching movement. As will be understood, the inward. shifting of the wheel from the action of the deflecting flange is for a distance sufiicient to insure against the wheel having end on engagement with the switch point and to a degree sufficient to relieve the extreme end portion of the switch point of excessive or damaging pressures. The uni-directional angular deflecting surface of substantially the full length of the device allows of materially reducing the length of the protector with resulting economy while providing a deflecting surface havinga relatively small angle adapted for effecting the desirable more gradual lateral shifting of the Wheel.

To allow of the reverse passage of the car Wheels in the non-switching direction the de fleeting flange is formed at its end portion spaced closest to the track rail with an up ward and outward inclination as indicated at 12operative upon being engaged by the car wheel to effect the inward movement of the latter thereby to avoid endwise engagement with the deflecting flange and-to allow passage thereby. There is accordingly provided a deflecting flange having an elongated angularly disposed deflecting surface operative inthe switching direction and an inclined vertically acting surface operative to accomplish the shifting of the wheel upon engagement when running in the opposite direction.

The latter surface as shown is of progressively decreasing angularity toward the center of the device to merge into the vertical wall or surface 12.

The substantially full length deflecting surface of my improved design, as illustrated, allows of positioning the device in advance of the switch point while obtaining effective close relation of the innermost point of the deflecting flange with reference thereto whereby the shifting movement given to the wheel will substantially converge into the switching action of the switch point. This advance position allows of securing the device to the track rail without interference with the switch point and its accessories and in further accordance with my improved design the securing of the protector member is accomplished without bolting to the rail. To this end, the base portion 3 is formed with an inner tie plate extension 14 arranged to underlie the track rail and having a raised shoulder 15 at its inner end positioned to engage the inner side of the rail flange for opposing outward movement of the protector member. For offering additional security against lateral movement the base portion is provided with inner and outer spike apertures 1617 as shown for spiking to the tie. To supplement the spikes in securing the protector member against longitudinal movement, the base portion is formed at its ends with depending flanges or shoulders 19 for engagement with the sides of the ties.

In Fig. 5 I have illustrated an approved modified embodiment of the features of my invention in a design adapted to be secured to two adjacent ties and suitably elongated to give a more gradual deflecting action more suitably adapted for switching points of higher speeds. In this modified form the head portion is of similar but elongated form relative to the design as first disclosed and the base portion is formed at its ends with tie plate enlargements 2O formed at their inner end portions with rail flange engaging shoulders 21. The outer end portions of the tie plate enlargements are provided with central transversely extending ribs 22 connecting the plates with the head portion as shown. The base further includes an intermediate or connecting portion 24 bridging the ties and connecting ribs 26 are provided as indicated connecting the base and the head portion intermediate of the tie plate portions for reinforcing the structure. The tilt opposing shoulder 6 in this modified form is shown non-continuous as aseries of longitudinally disposed shoulder extensions of the head portion.
