wHEEL-LocKrNG' DOG;

Application filed October To all whom 'it may conccm:

Be it known that I, EPHRIAM VV. MoRRIs, a citizen of the United States, residing at Rockwood, in the county of Roane vand State of Tennessee, have invented certain new and useful Improvements :in Wheel-Looking Dogs, of which the following is a specification, reference being had to the accompanyingdrawings. V

This invention relates to devices for locking railroad car wlieels for the purpose of either preventing the accidental movement of a car standing on a siding, forv instance, or for the purpose of skidding one pair of wlieels of a car so' as to permit the car to be shiftecl off the main line to a place where it: can be repaired.

It sometimes happens during the passage of a train over a railroad that the Wheels become' defective either by reason of the axle becoming beiit or the fiange broken or from other causes and thus cause a serious delay not only to the train upon which the break occurs but possibly to other trains following while the necessary repairs are made, which repairs are necessary in order to rcmo ve the same to clear the main line.

A method ordinarily employed is to place on the wheel a wheel clamp. This, however, is very hard to use and require special tools, which causes a delay to the train.

The object of my present in-Vention is to obviate this difficulty by providlng a wheel dog which is readily attachable without special tools over the flange of the wheel and which is so constructed that if the wheel is turned at all after the dog is in place the dog will bear against the arch bar and will jam upon the wheel and hold the wheel against further movement.

My invention is illustrated in the accompanying drawing, whereinz-f Figure 1 is a perspective view of my 1mproved dog applied to acar wheel;

Figure 2 is a pers ective view looking at the inner face of tlie wheel and showing how the bill of the hook engages with the wheel;

F igure- 3 is a Vertical sectional view through the wheel showing the manner in which the hook engages therewith and with the arch bar in order to jam or dog the wheel;

Figui'e 4 is a top plan view of the dog.

Referring to these drawings, it will be 28, l1924. Serial No. 746,428.

`lseen that iny emergency wheel dog consists of a casting, preferably of steel, having a Vbody 10, a Ashank 11 projecting from the body, and a hook 12. The shank 11 is less in depth than the bodylO so as to provide an end face or shoulder 12a for the body, and the inner face of the shank is obtusely angled, as at 13, between the beginning of the bill of the hook and the face 12a. VPreferably the lateral face-of the shank and of the integral body are reinforced by a longitudinally extending rib 14,. The inner face of the body is at right angles to the face lfl` while the outer face of the body is slightly inclined. p

This dog has a length sufficient so that it may beengaged over the flange of the wheel A and the lower face of the body will rest upon the arch bar B. The bill of the hook will' extend beneath the flange as, .for instance, as illustrated in the drawings` and between the strengthening ribs a of the wheel and the face 18 bears against the periphery of the wheel, while the angular face 12'* bears against the side face of the wheel i'im. as illustrated in Figure 3.

This device may be used for the purpose of preventing runaways on Velevate'd tracks` at inines, and where it is necessary on short line railroads to leave a car for some special purpose on the main line or on a siding. Under these circumstances sometimes the brakes become loosened during the loading of the car and the car run-s away down hill and sometimes passes onto the main line with disastrous results. When this device is attached as illustrated and there is any forward movement of the wheel, the device immediately turns upon the rim of the wheel and ams on the wheel and it is impossible for the wheel-to move fui'ther. When attached to a wheel it is impossible to remove the dog unless the engine backs the car. The slacking back of the car permits the dog to be detached. Thus there is no dangei' of the dog becoming accidentally loose.

The device is also particularly 'valuable in looking a wheel which has become damaged to perinit the car to be skidded from off the. main line to a place wliere it can be repaired. This device requires no tools to apply and noscrews to force in place, but can be applied by hand in a few seconds. The dog may be applied either on top of the arch bar or underneath the arch bar or in between the arch bars, and in all of these various situations Will act to hold the wheel from any further forward movement.

lVhile I have illustrated a construction which I have found to be extremely pra-otical, I do not Wish to be limited to this as it is obvous that many changes might be made in the details of construction and arrangement of parts Without departing` from the spirit of the inventon.

I claim 1-- 1. An emergency dog` for looking railway car Wheels comprising a straight body, an integral shank extending at a slight angleV from `the body and slightly offset With relation thereto to thereby provide a shoulder extendin'g doWnW-ard from the shank, the shank terminating in a hook, the bill of the hoolr extending from the body and the space between the -sho'ulder an'd the bill of the hook being' of sniticient depth to permit the hook to be disposed over the flange of the car wheel and extend inward of said flange to thereby perinit the end of the body to bear against the edge of the Wheel rim opposite the fiange.

2. An emergeney Wheel dog oomprising an i'ntegra'l casting formed to provide a straight body portion r-ectangular :in section, a Shanl extending at a sli'gh't angle to the body portion and terminating in a hook, the bill of which extends toward the adjacent end of the body, the hook being of sufiicient depth to permit the hook to be disposed over the flange of the car Wheel and extend beneath said flange, the distance between the bill of the hook and the end of the body being suf' ficient to permit the end of the body to bear again-stthe edge of the Wheel rim opposito the flange.

3. An emergency Wheel dog formed to provide a body portion rectangnlar in section a shank extendng from the body portion and terminating in a hook, the shank at its jnnction With the hook being formed with .a shoulder upon its lower face ad apted to :bear against the rm of a wheel, the bill of the hook .extendng toward the adjacent end of the body, the hook being of sufiicient depth to permi-t the hook :to be disposed over the fiange of the car wheel and extend beneath said flang'e, the distanoe between the bill of the hool: and the shoulder on the body being snfficient to perniit the shoulder to bear .against the Wheel ri'm opposite said fiange.

In testimony whereof I hereunto -affix my signature.

EPHRJAM VV. MORRIS.
