. when upon a siding orthe like, and it has l5 adjustable so that it may accommodate itfor its object primarily tov provide a simple and inexpensive device of this class that is self properly to rails of various sizes and .which when in use may be readily manipulated either to adjust it according to the size of the rail or to lock or unlock it, the device when in locked position uniformly distributin the force of resistance when the pressure is rought against it by the car wheel, and the device moreover is so constructed that it clears the flange of the wheel when locked so as to prevent fracture of the flange, and when unlocked it will be thrown clear of the rail by the car wheel should the device be inadvertently left upon the rail, derailment being thereby prevented.

To these' and other ends, the invention consists in certain improvements, and combinations and arrangements of parts, all as will be hereinafter more fully described, the novel features being pointed out particularly in the claims at the end of the specification.

In the. accompanying drawing: Figure 1 is a perspective view of an adjustable car stop constructed in accordance with my present invention, the same being shown applied to a railroad rail; Fi 2 represents avertical section through he rail and the stop fitted thereon, the locking lever being shown in partially locked position; Fig. 3 reprel sents a side elevation of the device, the locking lever thereon being shown in the same position it occupies in Fig. 2; and Figa is a perspective view of the locking lever.

Similar parts are designated by the same reference characters in the several views. Adjustable car stops constructed in accordance with the present invention are capable of use in connection with rails of various sizes and shapes, 'although in the present instance, I have shown them adapted for use in connectionmwith the ordinary block.

-T-rail such as used generally on railroads.

rlfhe stop consists of a-block be composed of cast or wrought iron and one side of the block adjacent to its lower edge is recessed so as to enable the block to lit upon the ball 2 of the rail and also to" engage beneath the ball ci' the rail whereby the block may be locked down on the top l' which may oi the rail. This recess in the present instance is so shaped as to torni a horizontal wall 3 which rests llatwise on the upper side of the ball of the rail and the lower wall fi of the recess is preferably inclined so as to fit and engage the under side ot' the ball of -the rail, the 1nner side or the block below fie inclined wall Ll extending vertically au at 5 so as to rest against the web oi? the railand thereby prevent turning or tilting` of the The upper portion of the block is reterably ot' such a width that its inside tace is contained within .the width of the ball of the -rail as shown in Fig. 2, and consequently the flange upon the car Wheel will not be struck by the block andin this manner fracture ot' the wheel 'flange is prevented. A bolt 6 extends horizontally through. the upper portion of the block and is freelyV turnable therein, this bolt having a capstan head 7 serving as a shoulder at theouter side of the block, and in order to facilitate the adjustment ot' the device especially Without the use ot' a wrench or other tool, this head is provided with a handle 8 which may slide through the head and enable the operator to easily adjust the bolt. The locking lever 9 is turnable about the bolt G as an axis and in order to enable the leverto be adjusted with respect to the block so that the device may be fitted to rails of dill'erent sizes,the bolt 6 is formed with a thread 10, a left hand thread being shown Ain the present inst-ance vand this threaded end of the bolt cooperates with the lever 9. This lever 9 is composed of a handle portion which may be of any appropriate length that will enable the device to be locked and unlocked with facility, and it also has a cam portion -11 which extends in approxi' struction on the track. This cam portion is provided with a slope or incline l2 at its inner 'side and at one corner7 this slope or incline cooperating with the inner side of the ball ol the rail when the handle ot' the lever is depressed and thereby causing a locking;` action ot' the lever and block upon the r-ail that is interposed 'between there. ln the present'y instance, the left hand thread of the boltl (i acts to assist theycarn 12 in locking the block upon the rail While the lever is beurey turned into locked position. When the stop is in locked position upon the rail, the inner t'ace of the block is olt'set outwardly troni the inner tace of the ball of the rail, and consequently, the tread only ol` the ear wheel will strike the stop, the tlange of the wheel passing clar of the block at its inner side and thereby avoiding injury to the wheel llange. Should it hap-- pen that the stop is unlocked buty the car wheel strikes itbet'ore it has been removed from the rail, the block would be engaged by the Wheel and would be thereby thrown clear ot the rail. y

Obviously, the invention is cz able of use in all instances where it is desirable or necessary to limit or prevent movement of a car or cars, it being especially useful on coal chutes, elevators, mines and in similar instances for the purpose of stopping a car either loaded or empty at a given point after the ear has been set in motion for instance by a pinch bar or by hand power.

claim as my invention:

`l. A car stop'comprising a pair of pivotn ally connected members, one adapted to engage a side of a rail and the other turnable and having means for producing a Wedging action against the opposite side et a rail and to thereby lock the stop thereto.

2. A ear stop eomprisino a block adapted to engage one side oit' a rai and a lever pityotally connected to said bloelr en anais transverse to the rail and arranged to engage' the opposite side or the rail to clamp the block thereto. i

3. carstop comprising a .block shapedl at one side to receive the ball of a rail, and a lever turnable about an axis transverse to the rail and comprising a handle portion, and a cam portion depending in angular relation thereto and shaped to cooperate with the ball of the rail at one side.

5. An adjustable ear stop comprising a block recessed at one side to receive the ball of a rail1 a lever having a cam portion at its inner side to'-`-coiperate with that side of the ball of the rail opposite to the side received by said block, and a bolt servingas au adjustable pivot connecting' the block and .lever 1 whereby the stop niav be ad Justed to rails of ditterent sizes. l

6. An adjustable car stopcomprislngl .a bleckshaped to receive the ballV of a rail, a

to thereby lock lever having` a earn portion to engage the'y rail, and a bolt turnable in the block and threaded into the lever and serving as an adjustable pivot to adaptthe stop to rails of different sizes.

7. An adjustable cary stop comprising a bloei; shaped to receive the ball of a rail, a lever havingI a portion to directly engage the ball of the rail to thereby lock the block thereto,-and a bolt 'forming a pivot, for said lever, said bolt'being threaded and having its pitch sodarranged that turning of the lever willy cause block. in testimony the lever to approach the whereof have hereunto set my hand in presence of two subscribing wit ncsses. l
