DERAIL.

Application filed April 8,

This invention is an improvement in derailing devices and relates particularly to that class of derail in which the movable derailing block is operated by connections from a switch stand'whereby it is moved from a lowcrating position upon the rail and vice versa.

An important feature 01' the present invention consists of an improved structure and arrangement of the parts providingfor an improved mode of operation whereby the der'ailing block as it approaches the operat ing position upon the rail will have a move ment which closely approximates a vertical movement as a result of which it will effect proper bearing engagement with rail sections of differing heights. To eilectthe desired movement I have provided that the standard and derailing block members shall have oper ating bearing surfaces at the forward or rail end of the device that are inclined and angularly disposed to produce a lifting action having a: substantially vertical component by reason of the shifting of the hearing points of cont-act both in the longitudinal and transverse planes. Other important features of my improved device comprise an improved form and design of the derailing bloekpro'viding a supplemental defiectingor derailing flange positioned to be engaged by the car wheel rearward of the main deflecting flange in the event of the car wheel jumping over the latter, thereby introducing an added safety factor; further, in the" provision of a base plate extension of the standard member positioned to underlie the track rail thereby allowing of more firmly securlngthe derailing device in position with relation to the rail and in eliect as a part of the track structure. p

The ioregong and other important features and advantages of my'p'resent improvements will be more fully understood by reference to the accompanying drawings wherein like reierence characters are applied to the corre-' sponding parts in the sevei'al views.

I V i Fig. 6 is a View in rear end elevation of the derail block member and Y F ig; 7 is a view in side elevation of the block mernben I In the approved embodiment of the features of my invention as hereillustrated, the i derail comprises the base structure comprismg a single casting and a one piece d'erailing block member having bearing engagement with the standard and arranged to be movable thereon toward and from the rail by movement transmitted theretoby connections from a switch stand and wherein the movement imparted to the derailing block is determined by the form and arrangement of the co-acting bearing surfaces oi the standard and block members. The standard or base structure as here shown comprises, as a one piece casting, the vertically positioned side walls 1, base flanges 2, extending horizontally therefrom at opposite sides for bearingengagement upon adjacent-ties, forwardly ex tending tie plate members 33, positioned to underlie the track rail and provided with spike apertures to receive the usualsecuring The side walls are united at their rearward and upper portions by an inclined connecting rooff: wall -5, the latter aiiording protection to the operating connection and bearings as will be hereinafter more fully understood.

. The derailing block member isindicated at 7 5 and is formed with the usual angularly disposed derailing flange 8, and'at'its under side is formed or cut away at 9, to overlie the track railand .to have shoulder engagement therewith atthe side of the rail head. The derail;

ing block member 7, has integrally formed' therewith, the bearing portion or lateral extension 10, comprising a central vertical web portion 11, tor-med at its lower portion with opposite lateralflan ges 12, andat its forward end with .outwardiy and do wi'lward-l ly projecting flange portions 13l3, and at its extreme rearward portion is formed with the aperture'd bearing 15, for the reception of connecting pin for connecting to suitable op} erating connection from a switch stand; The

bearing portion of the derailing block is provided at'its opposite sides with forward and rearward bearing projections or shoulders 16 and 17, adapted to have sliding bearing engagement with hearing flanges or ways provided therefor upon the standard or base member. As here shown, the slideway bear-' ings are formed by means of inwardly projectingfianges 18 and 19, on each of the side walls of the standard, theforwardly positioned bearing flanges 18, being arranged to be engaged by the forward bearing shoulder 16, of the block member, and the rearward bearing flanges 19, being positioned to be operatively engaged by the bearing shoulders 17, of the block. Complemental to the lower bearing flanges 1 8 and 19 of-the standard there are provided upper inwardlyrprojecting bearing flanges 21, in suitably spaced relation to the lower bearing flanges to provide slideways for confining the bearing projections of the derailing block to determine the r q extending and'angularly disposed main desliding movement thereof.

In accordance with an improved featureof the present improvements, the slideway bearings of the standard and the co-acting bearing'shoulders of the derailing block member are peculiarly formed and arranged to determine that the movement of the derailing block from its rearmost position away from the rail shall be forward and with a lifting movement to carry the derailing block proper above, the rail and whereby at the extremity of the forward movement the head portion of the block will be lowered throughout a substantial movement in-approximately a vertical plane. As a consequence, and as will be appreciated, the improved movement will accommodateand allow of the device being employed with rail sections of varying height and thereby effecting substantial economy in pattern equipment. 7 To this end and as here shown, the forward bearing flanges 18, of the standard are formed with downwardlyand rearwardly inclined portions 24, operative to effect the lowering of the derailing head when in rearmost position, and at their forward ends being formed with downwardly and forproviding a convenient hand hold for manu wardly inclined portions '25, which in addition have theirbearing surface angularly disposed with respect to the longitudinal axis of the guideways. For operatively engaging therewith, the shoulder projection 16, of the derailing block, in additionto being laterally projecting, have their engaging surfaces angularly disposed with relation to the axis of the guideways whereby in the movement of the block member from extreme forward position in the rearward direction, the shoulder bearing 16, .will ride upwardly on the inclined flange bearing25, with a lateral shifting of the bearing point of contact effective to impart a vertical component to the movement of the derailing member duringthe initial period of its movement. lhe flangeway bearing the derailing block on to the rail, in conjunction with the action of the forward. hearings, in close approximation to a vertical movement.", g j f I The derailing block is further designed to incorporate features of advantage over types as heretofore employed and accordingly is formed as shown, with the 'longiti'idinally fleeting flange 8, andprovided at the entry end with the usual flange groove 29, and inclined tread surface 30. In accordance with thepresent improvements to the rearward of the main deflecting flange, there is-provided the supplemental deflecting flange 31, positioned to be effective with a derailin movement should the wheel, by reason or its velocity, ride over the main deflecting fiangefi, and accordingly there is an additional safety factor provided for.

Additional structural features of improve- 10G ment as herein provided, consist in providmg depending extension 33, of the side walls of the standard for bearing engagement against the sides of the ties and forward extensions 34, of the side walls, adapted to bear against the web portions of the track rails thereby determining the spaced relation of the derailing device thereto, the latter being of a' contour to provide for the required clearance of rail sect-ions of'varied sizes.

The derailing block member at the rearward portion of its head portion, is formed with a downwardly curved ledge portion 35,

ally operating the device when desired. 7

' I have accordingly produced an improved 'derailing device which in its operation will determine the movement of the derailing block with a path of movement which is such as to properly co-act with rail sections of ber movably. associated therewith and provided with co-acting' bearing surfaces, said bearing surfaces effective at the extreme for- Ward position of the derail member comprising downwardly andfo'rwardly inclined bearing surfaces on the standard angularly disposed with relation to the path of movement of the derail member and co-acting surfaces on the derail member angularly disposed to said path of movement to provide a shifting point of bearing contact and to impart a vertical component to the movement of the derail head.
