CARSTOP Filed April 27, 1931 .2 Sheets-Sheet 2 Patented Mar. 1, 1932 UNETED STATES JOHN V. STEWART, OF JOHNSTOWN, PENNSYLVANIA CARSTOP Application filed April 27, 1931. Serial No. 533,298.

My invention relates to stops for railroad cars, and particularly to an improvement on the type applicable to arail, and transmitting I car stopping shocks to one of the rail support: ing ties. 7

Such a stop Ordinarily has a depending end part contacting the tie, the other end being bolted to the rail to keep the stop from tilting when struck by a car wheel. Being quite 1O immovable along the rail, this latter end sub jects the stop to a severe stress. for which it is not designed, as it prevents stopping shocks frombeing properly transmitted to the tie thru the depending end in the manner intended. Frequent breakage of the stop consequently results from this condition.

It is my intention to provide a stop of the general character just described, which may be fixed down on the rail to prevent tilting,

' 20 but which will properly transmit stopping shocks to the tie, the consequential breakage being thereby diminished. I further intend to provide a stop that may be simply and inexpensively made, and is of a generally improved character.

In the drawings:

Figure 1 is a specific example of a wheelstop constructed in accordance with my 111- vention, and applied to a railroad rail.

Figure 2 is a cross section on the line IIII of Figure 1.

Figure 3, a cross section on the line III-III of Figure 1. These drawings show a railroad rail A, supported by the usual ties-B, and straddled by a car-stop C. I ate wheel engaging portion 4:, and a palr oi depending apertured' abutments 5, the latter being positioned against one of the ties B,

and preferably fastened thereto by spikes 6.

To prevent the stop from tilting up when struck by a car wheel, it is firmly clamped to the rail A by means of an inverted U-bolt 7, the ends of this bolt extending up each side of the rail, and thru a pair of apertured lugs 8, which straddle the rail, and are formed in the base of the stop, where it is secured by nuts 9. The crossbar of the U-bolt 7 carries a revoluble bearing sleeve 10 which contacts 5 3 the bottom of the rail A.

This car-stop includes an arcu The car-stop C also includes a pair of opposed lateral guideways 12, positioned directly beneath the bolt receiving apertures 8, and each'carry'ing a guide plate 13 having an aperture 14:. These guide plat-es13 extend inward to contact the web of the rail A, the ends of the U-bolt 7 passing thru the aperture ll in each to retain it in position.

Inuse, such a car-stop is placed on a rail,

with its abutments contacting one of theyrail supporting ties, spikes preferably then being driven into this 'tie thru the holes in the abutments to insure a vertical position of the stop. Then the guide'plates are slid into the guideways in the stop, and the U-bolt is inserted, so that the revoluble sleeve it carries tilt up when stopping a car, yet, because of the anti-friction element, it will'be able to transmit the stopping shock to one of the ties in the manner it should. This will avoid any breakage because of the shock being taken up by the car-stop in an improper manner.

The guide plates will contact the web of the D rail to prevent sidewise movement of the stop, and possible deformation of the U-bolt.

WVhile I have shown and described one specific form of my invention it will be understood that I.do not wish to be limited thereto, since various modifications may be made without departing from the scope of my invention, as defined in the appended claims.

I claim:

1. A car stop comprising a body constructed for application to a railroad rail so as to stop a wheel rolling thereon and to transmit the stopping shock to one of the rail supporting ties, and an inverted U- shaped bolt arranged under the bottom of the rail to which the wheel stop is applied and with its ends extending up on each side thereof to engage said body, the crossbar of said U-shaped bolt being provided with LL;

a revoluble member bearing on the bottom of the rail.

2. A car-stop comprising a body constructed for application to a railroad rail so as to stop a Wheel rolling" thereon and to transmit the stopping shock to one of the rail supporting ties, said body having a pair of a-pertured lugs straddling the railto which itis applied, a pair of opposed lateral guideways beneath said apertures, an apertured guide member in each of said guide- Ways so as to contact the Web of the rail, and an inverted U-bolt arranged under the bottom of the rail with its ends extending up on each side thereof and thru the apertures in said guide members and the apertures in said body.

3 A car-stop comprising a body construoted for application to a railroad rail so as to stop a Wheel rolling thereon and to transmit the stopping shock to one of the I rail supporting ties, said body having a pair of apertured lugs straddling the rail to Which it is applied, a pair of opposed lateral guide- ,Ways beneath said apertures, an apertured guide member in each of said guidevvays so as to contact the Web of the rail, an inverted U-bolt arranged under the bottom of the rail with its ends extending up on each side thereof thru the apertures in said guide members and the apertures in said body, and arevolubie bearing member carried by the crossbar of said U-bolt and contacting the bottom of the rail.

' In testimony whereof, I have hereunto set my hand.

JOHN V. STEWART.
