WHEEL BAIL-CLAMP.

T o all whom it may' concern Be it known that I, WILLIAM BoD'rrE, a citizen of the United States, residing at Empire, Canal Zone, have invented new and useful Improvements in lVheel Rail-Clamps, of which the following is a specification.l

The present invention relates to a new and improved stay which may be used -in the nature of a chock for 'holding either a car, excavator, derrick or the like against movement on the rails of a track, andthe improvement resides 4in the construction, combination and operative arrangeinentof parts set forth inthe following description and falling within the scope of 'the'appended claims.

In the drawings: Figure l is a perspecf tive view of a wheel chock embodying my improvement as secured in posit-ion on a rail,-F,ig. '2 is a .view in side elevation of Y my improvement, Fig. 3 is a transverse'scc- V'tional view upon theline 3-3 of Fig. 2,

1`Fig. 4 is a. horizontal' sectional vview upon vthe line L -4 of Fig. 3. `In the Ause of machines such as excavators, 'derricks and the like, adapted' tolle oper-VA ated and moved from place toplace on rails',- it is necessary that the movement-.of the machine along the .rails be prevented when t! is desired to operate the machine in any fixed position. The force tending to move the machine along the rails is great, especially where the power of the machine is exerted lengthwise of the track, as for example, in the operation of a scraper bucket excavator, when the bucket is drawn toward the machine on a liucl substantially parallel with the track.- It is, therefore, necessary that devices used to hold the machine in a tixed position upon the rails be strorg and effective, and at the same time ready reinoval or adjustment of position may be obtained without loss of timel or labor. It is' also desirable to provide such a chock with means whereby the saine may be par-A tially disengaged from thc truck in order to permit of the said chock being slid by the wheels of the machine to which it is attai-lied, a certain and desired distance when the machine isto bc brought from one point to another without. necessitating the operator of the machine leaving his position upon the machine."

I accomplish tlie'above-nained desired purpose through the medium of the apparatas, and its operative applica-tion illus- Specification, of Letters Patent. Application tiled January 21, 1918. Serial No. 743,359.

proved chock or stay and 2 the track tl-`IV which thestay is attached. The chock embodies essentially. a pair of side membersfor wings, lwhich are designated by the'numer--- als 3 and 4 respectively.A Both of tliesef-A wings embody fiat-metallic members eachv being of a sutiicient strength to etectively withstand the strain to which it is sub. jected. As shown in the drawings, each of the wings ,and 4 preferably comprises a fiat member, and each of the said members has its upper and inner edge'preferably integrally formed with longitudinally extending lugs 5. the same being preferably three in number and one larranged centrally of the member 3 and the remaining pair arranged to the opposite sides of the member 4 and disposed adjacent the opposite ends of the lug upon the member Secured upon one of the lugs -5 of the member 4' and arranged upon tlieupper face thereof is a. projecting eye 7, and `the member 3 directly belowdtsJrig 5 is integrally VAformed with a lutcrall"extending tongue 8 -which extends througllanelongated angularly arranged' i opening 10, the saidopening heilig adaptedv to receive a wedge member 1L A Arranged to the lower longitudinal edges of each of` the members 3 and tand upon the inner face thereof are ribs -12 and 13 respectively, whilc'disposed at a distance above the said ribs equal to Vthe thickness of'the heads of the rails are second rib members' 14 and 15 respectively. These' ribs are, of course, of a lesser thickness than the lugs' 5, and each of the said lugs has its innerface rounded and bearing againstI the inncr face of the adjacent wing or plate to permit of the lower portions of the Said plates bcin'g readily swung toward each` other when the wedge ll is inserted through the opening tl of thc tongue S. and. if desired, the faces ot' thc ings between the ribs l2 alid l-l and li and l5 rcs|urctivelyll may be iougliencd to engage with the opposite faces of the heads of the rails, and thus serve asan additional means for preventing the longitudinal iiiovcnientof the chock when connected with the rails. .Uso if desired, the lugs may be provided with longitudinal openings for the reception of a pintle a. whereby the wings may liingedly connected. f

One of the transverse edges of the wing be lilo I i? A member 4 1s or a curved 0r arcuate shape, as

designated by the numeral 16, as is also the end 17 of the section 3 which is arranged upon this side of the chock, the said curvature corresponding with the car'fwheel with which the chock engais' heretofore stated, 1t 1s desirable that.

u the chock remain a permanent attachment' which has v the wedge member 11 is an additional flexi-` ble element5l9Lf-3It will be noted that by exerting a ulliupon the element 19, thewedge mem er Il will be partially withdrawn from its engagement with the tongue. 8, Aandas the chock is thus broughtout of tight frictional engagement with the rail, a movement o-the wheel which contacts with the chock will slide the same along the rail. The wedge may be provided with a removable stop pin b' which willprevent the entire withdrawal of the Wedge and thewedge may be of sufficient weight `into locking position when leased.'

From the a5 to gravitate the cham is referegoing description, taken in drawings, the simplicity lof the device, as well as the advantages thereof, will it is thought -be perfectly apparent to those skilledin the art to which such inventions appertain.

Having thus described the invention, what I claim is:

. 1. A wheel chock comprising a chock member embodyingr separate wings having their inner faces adjacent their upper ed es provided with abutting lugs, the wings ie-1 ing provided with rail receiving passages disposed below the lugs, and a removable the peripheryA of .wedge member cooperating with an element provided upon one of the 'wing members and adapted to frictionally engage with the side of the second'wing member.

2. A wheel chock comprising a chock member, a' pair of fiat wing members having their inner faces provided with inturned Mspect'ive wing members, each of the wings having its inner face provided with spaced vlongitudinally extending ribs forming rail engaging passages,A anda gravity wedge member `co-acting vwith' an element upon one f tionally contact withv the outer face of the second Wing member.

3. A wheel chockz-.comprisin member constructed of a pair o having co-acting fulcrum members, said .win'gs being provided with rail passages, one of the Wings having a tongue which is adapted to extend through 'an opening in the second wing, and a Agravity wedge engaging the. tongue and frictionallyv contacting with the outer face of one of .the wing members.

a chocld constructed of a pair of hinged wings, the said wings being provided with rail receivf ing passages disposedbelow their hinge, one of the Wings having an angular tongue which projects through 'an opening in the lsecond wing, said tongue being provided with an inclined slot, a gravity wedge arranged within the inclined slot .ing with the outer face of one of the wings of the chock and a flexible element for the gravity wedge.

In testimony whereof I atlix myl signature in presence of two witnesses.l
