. The invention relates to wheel stopsi'o f the 'typeadapted to be applied to carralls at various points to engage a car wheel and prevent movement of the car along the track irrespective of the functioning of the car handbrake. The-main objectof the present invention is to provide a simple,.economical effective stop'easily applied to and removedzfrom the I rail without drilling or other. work on the rail and, preferably, to provide a wheel stop which ,will I automatically tighten itself to the-rail irrespective. of. careful applicatlon by'the user and irrespectiveof wearer other conditions which might tend temporarily to loosen the device; I 1 v In the accompanying drawings 1llustratring the invention Figure 1 is a side elevation of asimple lformof stop showing the trafiic rail to which it is applied and a car wheel engaged by th p' l I 0 1 Figure2 is .a transverse vertlcal sect on on the line '2--2 of Figure 1. p

Figure .10 details an element used in the structure of Figure 9.

Figure 11 is mainly a side view but with a, portion sectioned longitudinally illustrating another form of the invention.

' The traflic raill is shown "mounted on cross ties 2in the usual manner. .Thestop device. includes a block-like body 3 having a grooved underface 4 arranged to rest upon the rail substantially throughout the length of the device, .Bloclr3 has a forwardly fac- 'ing'wheel engaging surface 5 preferably pro- 'vided with the same contour as the wheel 6. The rear portion of body 3 tapers. downwardly andrearwardly from the wheel engaging portion and includes an upwardly facing surface 7. Aloop member encircles the rail and the rear portion of the body of the deviceand comprises a U-shapedstrap 8iand a transverse, key 9v extending through suitable openings provided therefor in the upper portions of the legs of the strap 8.

of the block along the rail. The lower portion 'of strap 8 will abut against the forward face of one ofthe cross ties if the'frictionalj'resistanceto the movementof the blolck is insulficient to lock the same to the ra1 l The'form shown in Figures 3 and 4 includes a similar stop block l2and a downwardly opening inverted U-shaped member 13 of round rod having eyes15 formed in the lowerends ofits legs for receiving. a holding pin 14. a The tapered surface 16 of the block corresponds. to .surface 7 in'Figure .1 and acts as a wedge to tighten theassembly of the device with the rail as Wheel pressure is applied to the block.

v Figures 5 and 6 illustratea. structurein which the block. body 17 has a longitudinal groove 18 in its inclined upper face and the sides of this groove are perforated at intervals as indicated at 19,. A separate lug 20 the block by a pin 21 passing through opentioned by lug I v This construction adapts the device for application to rails of different heights and si'zes the full line showingof lug 20 and loop member 22 indicating the application to a relatively high rail and thedotted line showmay be positioned at various points along" gaging element having a rearwardly and -downwardly inclined wedge-like portion constructed to, overlie the rail, anda' loop member 'arranged'to encircle the rail and saidportion. i

the lower face of the wedge-shaped key 27 passing through the sides of the strap 28.

This notch and key construction also adapts.

the device for application to rails of different heights. 1 y In Figure 11, the body 29 has an upstanding rear wall 30 threaded to receive the screw 31 which. extends longitudinally of the block. A loop. member 32 encirclesthe rail and the lower portion of'block29, passing through an inclined groove 33 in the block. Theinner end of screw 31 is provided with a seat 34 forthe upper'cross bar 35 of the loop member and by rotating screw 31 the device may beadjusted tofitrail sections ofvarious SIZQS.

Each ofthe structures illustrates a wheel engaging block having. a wedge-like body extending lengthwise of the rail'and pro.-

vid'edwith a simple loopfor holdingthe device to the rail andanymovement; of the body along the rail under the thrust of the wheel will serve to increase the resistance" of the device to. such movement:

Various other forms ofth e invention may be made without departingfrom"the spirit thereofand the exclusive use of modified details of the construction coming "withinthe "scope ofthe claims is contemplated.

What is claimedv is: 1. A wheel stop consisting'of' a wheel en- 2. A wheel stop consisting of a wheel engaging element having" a rearwardly and downwardly inclined wedge-like portion constucted to overlie the rail, and a loop memberarranged to encircle the rail and said portion, said loop member including a Wedgelikeelement extending transversely of the device and'movable through said member to reduce its effective length. 7

3. In a wheel stop, ablock arranged to lie upon the. top ofa rail with its forward end disposed to engage a car wheel and with'its top face inclined downwardly and'rearwardly from said forward end, and a link member overlying said top face and constructed to underlie the rail, whereby said block will be clamped to the. rail as it is moved rearwardly relative to'said member.

' 4:; A wheelstop compri'singa block constructed to lie upon a car rail and to project upwardly therefrom to engage a car wheel and having a top face inclined downwardly and rearwardly from its wheel engaging face, a U-shaped member constructed to receive said block and the rail between its legs, and a removable pin extending between-the outer ends of the legs of said U-shaped member.

-5. A wheel stop comprising a wedgedike block with its underside channeled to receive the head of a rail, a Ush'aped member applicable to said block and the rail upon which it rests, and a transverse wedge-like element extending through the-router portions of the legs of said member.

6. A'wheel stop comprising a wheel engaging block constructed to-rest-on top ofa car rail and having a portion inclined downwardly and'rearwardly from the wheel engaging face, a loop member forencircl-ing said "i block portion and the rail upon which it rests, and means for holding said loop member in position on said block.

7 A'wh'eel stop comprising a wheel engaging block'constructed to rest-ontop of acar rail and having a portion inclined down wardly and rearwardly fromthe wheel engaging face, a loop member for encircling said blockportion and; the rail upon which it rests, and means for holding said loop memher in different positions alongsaid inclined portion. r

8. A wheel stop comprising a-wheel engagingblock constructed to rest'on top ofa-car rail and'having a portion inclined downwardly and rearwardly from the wheel-err gaging face, a loop member for encircling said block portion andthera'il uponwhich it rests, and means for holding said loop mem- 7 her in different'positions alongsaid inclined portion, said means .compris'inga pluralityof notchestraversing said portion and adapted to receive the upper cross bar :of said loo p member. I

9. A wheel stop comprising a wheel engaging block constructed to rest .on top of'a car rail and'having a portion inclinedfdownwardly and rearwardly fromthe wheel engaging face, a loop member for'encirclin'g said block 7 portion and the rail upon .whichit rests,.an-d

means for holding saidloop member in difierent positions along said inclined portion, said means comprising an element bearingagainst the'rear faceof th'etop cross bar of said loop member and a devicefor positively moving said element forwardly alongsaid portion.

10. A wheel stop comprising a wheel engaging block constructed to restontop of a its car rail and havinga portion inclined downwardly and rearwardly from the wheel engaging, face, a loop member for encircling said'biock portion and the rail upon which it rests, and means for holding said loop member indifferent positions along said inclined portion, sald means comprising'a screw threaded into a part of said block and extending longitudinally of said inclined portion and engaging the rear face of the upper cross bar of said 100}; member.
