.TaaZZ whom-tammy concern Be itknownlthat JI, JOSEPH Hooiga citi- -zen` oftheaUnited States, residing .at Moosic,

.Details will :be ffound in the following specification, reference being had to the drawings whereim- Figure-1r isa left side ,viewgofA-this vdevice `aseits.1pai:ts .stand whenitis'in use. Figs. 2 and 3 are perspective viewswith jthe arms respectively=raised,and ilowered. Fig. 4 is a-sectional detail showingthe .fastening of Fig. 5 is :a ,section on -the v line ofa slight modification.

Thebase ortread ofY this chock block com- .prisesa-'shoe i1 /beveledfoff at its rear end Ias ati2, its :frontend or toe 3 being beveled onzits underside as 'at 4.and across thefup- :per .faceof `the shoe `is securedvor formed thereon anznpstanding-rib. 5 whose front end .isundercut or hooked-solas to leave an openy ing G.

'The parts f thus Ifar: described may .all be formed of one piece of metal, and the-lower face of the shoe is intended to travel on the ball of the rail R while the wheel 'W is intended to ride up over the shoe 1 and rest against the rib 5. The chock block is connected by a chain C with some part of the car as usual, the chain being connected with the front end or toe 3 of the shoe in any suitable manner as by means of a clevis 11 mounted thereon as seen in the drawings, and when the car is drawn along the rail it is obvious that the wheel will rest on the gspeeication of Leiters raient.

'lhisguide'is of ,general :,U-shape formation, comprising inner andV outerc arms 12 and 13 connected by shaft l111 -which passesfthrougha ,throat 6 of `the Vhookfgshaped rib For preventits escape .therefrom .'Ima-ke usevof a closure l5 which may'fwellbe a block secured upon the front end of the shoe as by bolts or screws 16 to render lit lremovable -whenthe `guide is tobe takenout yforfany rea-son. It will be seen from', the plan view .in the Vdrawings-that v the 4distance between Llthe farms 12 and l'fisgreater rthan-the ,com- Y Y Vbined width vof theshoe landzflange A7, and therefore the shaft lmay'both rotate and reciprocate. On that end of the rib opposite the shoulder 8- is Yformed a4 projection or .vlug 17 whose use isV best seen infFig.` 5.

,Normally the parts stand ,as in Fig. l,

:with the armlQresting` on thefshoulder and therefore4 thel entire lguide ystanding parallel withthe upperfaceof ,the shoe, `and in" this position the chock block .occupies the least .possible space .and can bestored with ease. V,l/Vhen it is to be used the entire guide is moved by sliding the shaft 14 in the opening 6 so as to free the guide arm 12 from the shoulder, then both arms are raised, and finally the other guide arm 13 is pressed inward against therib 5 above the lug 17,

at which time the arms will stand oblique to the shoe and will extend alongside the wheel W. The latter now rests on the shoe 1 and against the rib 5 and its flange passes down alongside the flange 7 of the chock block with the result that the position of the wheel on the shoe is such that the guide cannot move laterally through the rib and therefore the arm 13 cannot disengage the lug 17. Hence both arms of the guide are maintained in a raised position alongside the wheel, and the chock block as a whole cannot move laterally with respect to the wheel.

I have shown theshaft 14 as square, and if so it must fit the opening rather loosely. In Fig. 6 the square shaft 14 stands a little bias to the length of the guide arms 12', and the closure 15 is adjustable toward the rib 5 by means of a set screw 16. With this construction of the device it is obvious that when the guide arms are raised so that the square shaft has its faces parallel with those of the square opening 6, adjustment of the closure by means of the set screw clamps two opposite faces therein and holds the guide raised irrespective of its engagement withy the lug 17 which latter may therefore be used or not, although for safety sake I prefer to use it in any case.

IVith this construction of my device, as with that above described, the normal or storage position of parts is with one arm overlying the shoulder 8 so as to occupy the least space, but the working position is with both arms oblique to the shoe so that the guide straddles the wheel and the chock block is prevented from lateral movement with respect to the same. When the device is not in use the chain C is disconnectedY from the truck or other point of attachment and the entire article removed and laid aside.

I'Vhat I claim is:

1. In a chock block, the combination with a shoe, and a raised rib thereon; of a guide movably mounted through said rib and having arms adapted to lie parallel with the shoe or be raised above the same alongside the wheel, and means for holding them raised.

2. In a chock block, the combination with a shoe having a raised rib, and a iiange alongside the shoe and having a shoulder alongside the rib; of a guide movably mounted through said rib and having arms adapted to lie parallel with the shoe and one of them upon said shoulder or to be raised so as to stand astride the wheel, and means for holding them raised.

3. In a chock block, the combination with a shoe, a raised-rib thereon having a transverse opening, and a flange along one side of the shoe provided` with a shoulder extending alongside said rib; of a shaft rotatably mounted in said opening and of greater length than the rib so that it may be slid through such opening, arm-s fast on the ends of the shaft and one of them adapted nornially to rest on said shoulder, and a lug on the rib adapted to be engaged by one kof said arms when the latter are raised.

4. In a chock block, the combination with a shoe, a raised hook-shaped rib thereon, a

closure over the throat of said hook, and

means for fastening the closure in place; of a shaft loosely mounted in the throat ofthe hook, parallel arms projecting rigidly from the ends of said shaft, and means for holding them elevated at an angle to the shoe.

5. In a chock block, the combination with a shoe, an upstanding hook-shaped rib upon the same, a closure for the throat of said hook, the parts being shaped to produce a rectangular opening, and means for adjusting the position of the closure; of a guide including a pair of arms and a rectangular shaft connecting their forward ends and eX- tending through said opening, for the purpose set forth.

6. A chock block comprising a shoe bev-` eled'of on its upper face on its rear end and having its toe beveled off on its under face, a clevis on said toe, a flange secured to one side of the shoe and beveled off at the upper edge at its rear end, shouldered forward of said bevel, and deflected outward at its front end, and a rib rising from the shoe opposite said shoulder, combined with a guide movably mounted in said rib and comprising a pair of arms adapted to stand parallel with the shoe or oblique thereto and astride a car wheel.

In testimony whereof I affix my signature.
