RAILFASTENING.

Specification of Letters Patent. Patented Application iiledlebriiaryl, 1916. Serial No. 75,5537. I i

' To all whom may concern:

Be it known that I, WILLARD TALno'r'r, a citizen of the United States, residing at Spokane, in the county of Spokaneand State of Washington, have invented a new and useful Rail-Fastening, of which the following is'a specification. q

The device forming the subject matter of this application is a rail fastening, and the present invention aims to combine, in a novel .manner, with a railroad rail and'with a tie, a screw of novel form, the ends in view be-' ing so to arrange the parts that the upward ,pull ofthe rail will have a minimum effect on the screw. so far as lifting the screw is concerned, so to assemble the screw with the tie and with respect to the rail that the horizontal thrust of'therail will have no I threads of the screw and to position the. 'screw with respect tothe rail and the tie that a maximum hold forthe screw on the tie will be afforded: and, generally, to improve and to enhance the utility of-devices of the sort shown in this application.

With the above and other objects in view which willappear 'as the'des'cription proceeds, the invention resides in the'combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawing-:Figure 1 shows in top plan, a railroad rail assembled with a portion of a tie, through the instrumentality of the screw forming a part ofthis application; Fig. 2is a vertical cross section of the structure shown in Fig. 1; Fig. 3 is aside elevation ofthe screw, 4

In the accompanying drawings,'the numeral, 1 designates generally a tie ordinarily fashioned from wood. There appears in the drawings, a railroad rail 2 comprising a ball 3, a web 4, and a flange 5, the flange 5 resting on the upper surface of the tie l. I

In carrying out; the present invention 'means for resisting the upward pull of the agonal ead 7 a conical neck 8 and a shank -.9, the shank 9 being'provided adjacent its lower end with threads 10 and terminating at 1ts lower end in "a point 11. The lower face 12of the threads 10'are so disposed" with respect to the-upper faces 14 of the threads as to define a right angle.- I

The invention contemplates, preferably, the use of two'screws disposed upon opposite sides of the rail 1 but to simplify the description, the same will be confined to one screw;

The shank 9 of the screw 6 is threaded into; the tie 1 at an acute angle to the verti-- cal, and extends beneath the flange 5 of the rail as clearly shown in Fig. '2, thereby to increase. the. efliciency of the screw as a rail. The conical neck 8 is firmly wedged into the tie 1 to act as a stop-waterfoi; the screwhole. The head 7 engagesthe upper surface of the'flange 5 for the obvious parpose of-holding the rail, down onthe 't i e\' The inner edge of the neck "8 is in contact with the edge of theflange 5 of the rail and is vertically disposed, whereby the horizontal thrust of the rail will have no vertical component tending to lift thescrew. The outer edge of the head 7'- engages. the tie 1 to serve as a brace against the horizontal thrust of the rail, Owing to the fact that the upper and lower faces 1412.o f the threads '10 of the screw define a ninety degree angle, the hold of the screw on the tie 1 is en hanced, notably when theinclined position and extending beneath the flange thereby to 10( 4 increase the efiic1ency of the screw as a means for resisting the upward pull of the rail, theneck being firmly wedged into the tie to act as a stop-water for the screw hole, th i head overlappingthe upper surface of the flange, the/inner edge of the neck being in contact with the edge of the flange. and being vertically disposed whereby the hor1zontal thrust ofthe railwill have no vertical component. tending to lift the screw the 1'10 euter edge 0% we haad alga-aging the tie my own, 1 haw herele nfiixed my sigma-Ema same as a brace agmnst the honzoiglml thrust "mike presenw of twc nmesses. oi the rail and the screw having threads the 1" 1 1 rfir w Q PPH' find lower surfaces 035 which define f FIALBQi 5 a ninety degiee angle whereby the hold of "Witnesses: 1
