To all whom 'it may concern:

Be it known that I, PHILIP W. MOORE, a citizen of the 'United States, residing at of Illinois, have invented certain new and useful Improvements in Railway-Rail Stays, of which the following is a specification.

The device of the. present invention relates to a structure adapted to be positioned upon railway rails, for the purpose of preventing at the terminus of a grade or adjacent switches, and like places; andhafs for its object, to construct a stay which will be lightened by the cutting off of superfluous metal, and at the same time, retaining the strength of the stay so that its usefulness is not limpaired in any degree. j A further object of the invention is to provide a broad abutting. surface, which will rest against the rail tie, thus providing a broad'bearing surface for Jche rail stay against the tie; land another object is to form a head upon one of the members of the stay, which will serve as a driving head, against which a hammer or other instrument strikes when the stay is being positioned.

In devices of this character, lbecause of the cheapness' of construction, the reduced -cost of shipment, and ease of handling, the weight of the device enters materially into the practicability of construction. A device which is light in comparison with other devices of similar nature at present on the market, and which will require less metal than such devices, is a step in advancement in the art, because of the savings in the various ways heretofore set forth. And a device Of this character, which is lightn and cheap of construction, and which at the same time retains all of the strength and rigidity necessary -for a practical device, is what applicant has designed, and these 4are the.'

' movement of the rail is withstoodby the salient features of the presentinvention.

The invention further consists 1n the feaparts hereinafter described and claimed.

Vconstruction of the movable clamping mem- ",LInthedrawings, Figure l is a perspective ofthe completed stay; 1g. 2, a plan view; Fig. 3 a front elevation of the stay, showing l a rail held therein; Fig. 4, a side view of the stay; and Fig.l 5, aplan view of a modified ber.

The device, as shown in the drawings, coml prises a fixed clamping member 6 and a movable clamping member 7. The iXed clamping vmember comprisesv a body portion 8, having a diagonally extending groove 9 formed therein, and is provided with a rail gripping jaw l0. The movable section comprises a body portion 1l, which terminates in a downwardly projecting lia-nge 12, adapted to enter the groove 9 in the fixed vmember 6; and the movable member is provided with a rail gripping jaw 13, The fixed member is pro. vided with one or more downwardly projecting abutments 14, preferably one at either extremity of the front edge thereof, which abutments lie, in operation, against a railroad tie and prevent the fixed section G from movement during the creeping of the rail. It is against these abutments that the major portion of the strain is communicated, hence, these Surfaces, being of the substantial and broad nature showinwill remain durable and effective during usage.

As shown in Figs. l and 2, one of the side walls of the fixed member G is cut away, for a portion of its length to form a diagonally extending wall 17, and this wall terminates, at one end, adjacent to the edge of the diagonally extending slot 9, and 'at its other end adjacent the edge of the front wall of the .fixed membcr;`and formed in the space intermediate the terminus of the wall 17 and the front wall is the rail gripping member 10. It will be seen by a study of this construction that a great amount of metal is thus eliminated from the fixed section, but in view of the :fact that no great strain is placed upon the gripping member 10, tle small gripping surfacashown in this structure -does not impair in any way the elticiency of the device. It will also be seen that the abutments 14 arebroad, and upon these surfaces comes the greatest strain 1n operation. Thisy is because of the fact that thebroad nature and which is 'so sloped or anfront wall of the movable section' is cut away, thus eliminating at this point a quan# tity of superl'luous metal,` and yet the railgripping property of the section is not in any wayimpaired or decreased.

" In Fig. 5`is shown a modifiedconstruction of the movable clamping member, in which thel outer edge 20 is cut on a bevel, as atl 21,

cutting away the front corner 22. clamping memberformed in this manner possesses several distinct advantages: First, itallows` the downwardlydepending flange or tongue I12 to be easily engaged with the groove 9., vThis is`- due -to the fact that the clampingl member as thus for-med permits of atilting or canting of the member in order to enterf the tongue 12 into the groove 9, eliminating' any forcing. or driving such as 'is'necessary where the gripping jaw is overhanging along its entire 1engtli,such forcing or driving being undesirable because it requires more time and trouble, and frequently re'4 sults in the, opening of the front corner .of the jaw. And secondly, the construction shown in Fig. feliminates metal andV re#A duces theweight and cost of manufacture of the clamp, and at the same time does not impair its eiiiciency asafclamping member.

The operation is`as follows: Upon the' placing ofthe stay on the rail, the movable section 7' will be driven forward until the point has been reached` where the downwardly depending flange 12V will have traveled suiiciei'itly in the groove 9 to lock against the `walls. of said groove. This will locktlie two sections of the stay together, so that the movement or creeping of the rail will carry thetwo sections therewith, but

owingto the abutments 14 resting against the tie, the movement of the stay-wi1l be checked, and, as the sections of the stay are tightly 'gri ping theA rail, the movement ofthe rail will be thus arrested. And"'these abutments being, as shown, of substantial and brdad formation, will oder a large bear# ing surface against they tie andrwill serve'to-A resist any vfuitliei' "mevement of the ra il, thus L fixed; f'

preventing the creeping thereof.

The member is referred-to as a clamping member for the salie 'of convenience in description, as in actual operation there lwill, be a slight movement imparted thereto bythe movement ofthe rail. .A v
