Patented Mar. 7, 1933 ARNOLD rr. TOLD, or CHICAGO, ILLINors WHEEL s'ror Application filed .Tilly 30,1932' Serial No.'626,3885'.

The invention relates to devices applicable to railway tracks, and more particularly to the rail itself, for engaging car wheels to stop the movement of the car along the track.

ldh'eelstops, chocks orrail clamps for this purpose have long been in use and their general objects` will not be detailed here as all those working in the railway field are familiar therewith. f

provide asimple economical structure which may bereadily appliedV to a rail without any drilling or other work on the rail; to provide means for easily and securely clamping or attaching the wheel stop to the rail; and to adapt the device for rails of different sizes without requiring the use of interchangeable parts for .dierent size-drails. v

5' rlhese objects are attained by the structure illustrated inthe accompanying drawing in whichf Figure 1 is a side elevation of one form of the invention, showing it applied to a section of track.

1 Eachof the figures shows theinvention ap.- plied to a section of ordinary rail 1 which isnot a part of therinvention although the latter is only vuseful when applied to the rail. In Figure 17 he main or body part of the device consists of an upright casting or forging 2 having a lower edge 3 arranged to overlie the top face of the/rail 1 throughout tbe length of the body. The front edge 4 of the body is shaped'to correspond to the contour of a car wheel. i Guide lips L depend fromthe sides ofthe body. -A pair of in- The objects of the present invention are to y 'cludes' a body member 17 overlying the rail verted V-shaped yokes 5 straddle the lower element` 6 of the body and project downwardly at. the sides of the rail and toa point below the latter, A key l7 extends transversely of each yoke lacross the lower portion thereof vand through suitable openings provided in the arms of the yoke at a level which positions the key so that it may engage the lower face 8 yof the rail flange and as the key is driven homo it wedges the yokef and member 2 60 tightly against thetop of the rail whereby an vattemptto move member 2 along the rail will be-eftfectivelyresisted by friction between them. This friction will be increased because of the tendency of any'movement of member 65.. 2V along the rail to cant yokes 5 at gan angle therebyy cooperating with the wedge structure to tightly hold the wheel stop in position.

To further Vresist movement ofthe device alongtherail, yokes 5 are so spaced -longitu- 70 dinal'y of the device and are so shaped that each is arranged to engage an upright face of a respective cross tie 9.

Y The legs of the yokes engage the edges of the rail fiange and when the device is tightcned, the yokes not only hold member` 2 against movement longitudinally of the rail but also hold it upright against forces tending to overturn it.

Figures 3 and 4 illustrate a modification 80 in which' two complementary upright members v10y and 11 are, secured to eachother throughout a substantial portion of their Yheight and are shouldered as indicated at S to rest on top ofthe rail head. The sides of the shouldered portions extend downwardly from the upper portions of the device to a point below the bottom of the rail where they are engaged by a tapered'key 12 serving as a wedge to force the device downwardly as 'far' as possible. In this structure the front and rear edges 13and 14 of the upstanding plate members arev disposed to contact with the rear and front edges rey spectively of the cross ties 15 and 16 tor co- 95 operater with the wedging keys to prevent movement ofthe device along the rail.

The deviceshown inFigures 5 and 6 insubstantially throughout the length ofthe device, yokes 18 and 19 straddling member 17 and the rail 20 with their lower ends constructed to receive keys 21 and to engage the cross ties 22. Member 17 is grooved vertically near its forward end and the wheel engaging body member 24 has a hook 24a extending into the groove and under the crossbar of yoke 19 whereby member 24 is pivoted at the forward end of member 17 and a coil spring 25 is received in the housing 26 provided in part 24- and is seated upon a boss 27 provided therefor on member 17.

This structure provides a yielding wheel stop but utilizes the same wedge attaching member common te all. of the forms of the invention.

Figure 7 illustrates a modication of the wedge structure in which the key 28 is more slender and a cooperating key or shim 29 is notched to fix its position transversely of the depending elements 30. lf desired, the opposing faces of elements 28 and 29 may be serrated to more securely retain key 28 in positiony after it has been driven home.

In each of the forms of the invention the wedge key is providedwith a plurality of holes 31 adapted to receive a Cotter pin 32 to lock the key in position. Each modification embodies a very simple device comprising relatively few parts and arranged to bel applied to a rail at any point without drilling the latter for bolts or other attaching elements. 'llhe only tool required for application or removal of the device is a maul or hammer or any instrument with which a blow may be struck. The device is easily removed and shifted to another point as is frequently required on repair track work. If the installation is to be permanent, the member resting on the rail may be spot welded thereto as indicated at W. The device has a substantial bearing along the top face of the rail whichr tends to resist any overturning of the member under the forces applied thereto and, as previously pointed out, the wedge structure makes a single form of the device applicable to rails of different widths and heights.

rlhe details of the invention may be further modified without departing from the spirit of the invention and the exclusive use of such modifications as come within the scope of the claims is contemplated.

llVhat is claimed' is:
