"constructedfto engage and be securely anchored to thevarious sizes of rails 'com Fig. 8 is asimil'arylew of a modrfiedform, y

The clamping nfeansfor' the rearlegs i5 is are respectively for-medtoprovide outwardlyT opening tapered grooves-13 and 14 designed I v order that the post may be' securely' f 5 I anchored to the track'rails without drilling-or extending flanges of the rail bases. Cooperating clamping members 15 and 16 provided with similarly shaped rail base receiving grooves 17 and 18 respectively are designed to be drawn into clamping relation with the shoes by means of clamping bolts 19 passing through aligned openings in the respective shoes and clamping members.

As is most clearly apparent fromFig. '7,

each shoe is secured to its rail by four clamping bolts 19, two of which are associated with each of the blocks or flanges 21 extending b cneath the rail. Two corresponding clamping members cooperate-with each shoe, each clamping member beingdesigned to receive two of the clamping bolts 19. In order to provide a maximum bearing surface against the lower face of the rail and to prevent cramping of both the shoes and the clamping members, the vertical faces of those. portions 21 of the shoes'which are disposed beneath the rails are inclined longitudinally of the rail and similarly the vertical opposed faces ing beneath-the rail and provided with apertures 26 outside the rail for the reception of spikes by which the plate may be secured to the tie. Theseapertures have a stepped wall to enable the spikes to be driven close to the edge of the rail base, irrespective of the width of this base, which is" dependent, of course, upon the size of the rail. The plate 25 is also provided at one edge with a down:

wardly extending flange 20 forming an abut-,

ment engaging one vertical face of the tie which also assists 1n holdlng the shoe against displacement longitudinally of the track.

Spike receiving openings 30 may also be provided inside the rail for further securing the shoe to the underlying tie.

In some cases, the plate 25 may be dispensed with, and this modification is illustrated in Fig. 8. In other respects, this cone struction is similar to that just described in connection with Fig. 7. I I i Theimpact of a car against the head of. the bumping post will tend to spread the legs 5, and in orderto strengthen. the structure and overcome this spreading tendency, the

shoes '7 and Smay be formed to provide in-.

ward extensions 27 and 28 respectively, terminating in upwardly disposed lugs 29 and 31 adapted to receive a. tie bolt 32, best shown;

in Figs. 1 and 8, by which the shoes are rigidly oonnected together and held against separadrawali of these ends. The clamping member 35 is provided on its inner face with a tapered groove 37 for the reception of the outer flange at the rail base and'an inner clamping member 36 provided with a similar groove 88 is connected with and drawn toward the member 35 by clamping bolts 40. That'portion 89 of the clamping member 36 which extends beneath the rail, has its vertical face 43 disposed at an incline to the longitudinal axis of the'rail, and theopposed face 44 of the clamping member 35 is similarly inclined parallel to the face 43 so that maximum surface engagement with the bottom of the rail is provided and cramping of the clamping members is obviated in the same manner as previously explained in connection with the clamps-for the rear legs.

The opposite end of the member 35 is secured to the rail, as will be apparent from Figs. 1, 5, and 9, by a bolt 50, cooperating with an opposed clamping member 41. The wide body portion 42 of the clamp 35 has an enlarged portion 45, as previously explained,

for the reception of the end 12 of the front leg. 2 i

- It will be apparent from the foregoing that both the front and'rear legs of the post are securely anchored to the track rails by being clamped thereto. and that movement of the legs longitudinally of themrails is precludedi-by the friction exerted upon the rails by the tapered grooves of the clamping members, ,One or more of the inner faces of these grooves may, if preferred, be roughened to increase the clamping friction. The clamps shown and described for illustrative purposes are designed to engage the bases of the track rails, but obviously the clamps might be designed. if preferred to clamp just as securely'to the heads of the rails instead. The

tapered grooves which engage and clamp the rail adapt the device? for attachment to the rails of various sizes, consequently my post may universally be used, and requires no change for anchorage toany size of rail, and may be removed fromrails of one sizeand anchored to rails of another size without modification of the clamping members.

The impact of the ,car against the post,

which tends to spread the rear legs, similarly tends to draw the front legs together. To overcome this tendency of the front legs to draw together, I have provided aspacer in A the formof a-hollow pipe 47 extending between .theclamping members. 36, this pipe being of a length to just fit between the members 36 when the post is applied to rails of the largest size. 1 A tie .rod 48 extends through 47 and is anchored by nuts at each end thereof, indicated by-149. YVhen the post the spacer is applied to rails of smallersizes, the length of" the spacer may be augmented by the, ap-

plication of the washers atithe' ends of the spacer. The rear legs are' somewhat resilient, and while they are normally spaced 1 apart at their lower ends to engage the smallout modification Ito rails of various-sizes.

It is believed that my invention and many of itsinherent advantages will be understood from the foregoing without further descrip I tion' and it should be manifest that the details of construction illustrated and described are capable of considerable modification without departing from the spirit Ofthe nven- V tionas defined in the following. claims, T II claim: I
