13 Claims. 1

This invention relates to rail fastenings of the type in which a railway rail is yieldingly held against a support and, as one of its objects, aims to provide an improved fastening of this kind requiring relatively few parts which are adapted to i be economically manufactured and installed.

Another object of this invention is to provide an improved rail fastening which, although of a simple and inexpensive construction, will safely hold a rail in the desired position for a prolonged period of service and in a manner which will result in a minimum amount of deterioration of the tie.

Still another object of the present invention is to provide an improved rail fastening embodying a two-piece clamp and a load spring, and wherein one of the clamp pieces is rockable on a fulcrum formed by the other piece for yieldingly applying the load of the spring to the rail flange.

A further object of this invention is to provide an improved rail fastening embodying upper and lower clamp pieces and a loadingspring, and wherein the upper piece applies the load of the spring to the rail flange and the lower piece'applies the load of the spring to the tie plate and also forms a fulcrum on which the upper piece is rockable. 7

Yet another object is to provide an improved rail fastening of the character mentioned in which the fulcrum forming piece of the two-piece clamp is of a novel construction and cooperates with the tie plate or with the rail flange in a manner to prevent turning of the clamp about the stem of the fastening member.

The invention can be further briefly summarized as consisting in certan novel combinations and arrangements of parts hereinafter described particularly set out in the appended claims.

In the form of the invention illustrated in Figs. 1 and 2 there is shown a wood tie l2 having a tie plate l3 thereon and a railway rail i4 resting on the tie plate. The rail is ofa conventional type having a head Ma anda base flange l-tb; The tie plate 13 may-also. be of anonventional form and ishere shown as being a substantially rectangular metal plate havingthickened edge portions 15 extending substantially parallel with the rail andv such thickened portions having a sub-- stantially flat top surface it. The inner or adja; cent edges of the thickened portions l 5 form railgauging shoulders I! which extend along the edges of the base flange Mb. The tie plateglB also has suitable openings l8, in this instance three suohopenings, extending therethrough adjacent the shoulders IT. .The intermediate portion ofv the tie plate can be of substantially-uniform. thickness as here shown, in which casea desired inclination of the rail 14 can be obtained by- -pro vidingthe tie I2 with a sloping recess 29 therein in which the tie plateis located as shown in The improved rail fastening also includes a fastening member 2 i', a two-piece clamp compris-. ing upper and lower-members or pieces 22 and 23,- and a load-applying spring 24. When the tie 1-2. is a wooden tie as here shown the fasteningm'em: ber 2| is preferably in the formjof a screw spike havinga threaded stem portion 2m screwed; into the tie and a plain orunthreaded stem portion:

2 lbprojecting upwardly from thextie' through the.

substantially circular tie plate opening l8. :The spike is provided at its upper endwith a head. 25 which is located a substantialfdistance.above the flat surface l8 of the tie plate l3. L'Ihe'head 25'hasa'shoulder 25a on the underside thereofand a polygonal top portion 25b to which a'wrench.

or the like is adapted to be applied;

22 has an opening 22a therein through which the plain stem portion 2 lb of the fastening member extends and is of a length such that its inner end overlaps the base flange Nb of the rail Hi. The inner end of the clamp-piece 22 can be curved or bowed as shown in the drawings so as to pro" vide a rounded bearing portion 26 adaptedfor a rockable holding engagement with the top surface of the base flange Mix-The outer end of the clamp-piece 22 has a bearing portion -or;projection 21 of reduced width thereon which is en gageable in a fulcrum recess '28 provided on the lower clamp-piece 23. The reduced bearing per-- tion 21 can be obtained on the clamp-piece 22 by notching out the corners of the outer end of this piece, as indicated at 29 in Fig.3.

The lower piece 23 of the two-piece clampcom-z prises a chair-like angular member or clip constructed from sheet metal or plate stock by suitable stamping or forming operations. This piece includes a laterally extending plate portion 30 which under-lies the upper. piece 22' and has an opening 30a therein through which the stem portion 2| b of the fastening member extends." The of the tie plate l3. The upper edge of the up-- turned portion 3|, forms a support and fulcrum for the outer end of the upper clamp-piece 22 and contains the fulcrum recess 28 in which the bearing projection 21 is received. The seat portion 3'2 of the upturned portion 3| is formed by metal which is deflected or displaced from one side of the opening 30a duringthe shaping of this piece to the angular form shown in the draw:- ings. The fulcrum recess 28 is located between a pair of upstanding lugs 33 which engage inthe corner notches 29 of the outer end of the upper clamp-piece 22 when the latter is assembled on the lower piece as shown in Fig. 2 of the drawings.

The stem portion 2) of the'screw spike 2| is of a length such that the shoulderlfia, of the head "25 will be located a substantial distanceabove,

the upper piece 22 when the two pieces of the clamp are in their assembled position. The coil spring 24 is disposed around the stem portion 2 lb with its lower end seating on the upper piece 22 and is subjected to compression by the head 25 so that the piece 22 will apply a yieldable holding force to the base flange Nb of therail and the lower piece 23 will yieldingly apply a force to the tie plate 13 tending to hold the same against the tie l2. The height of the upturned portion 31 of the lower piece 23 can be varied in different specific fastenings of this construction but is preferably such that the upper. piece 22 will initially be in a downwardly and inwardly inclined position as shown in Fig. 2.

The upper piece 22 is held from turning about" the stem portion 2 lb ofthe fastening member by the engagement of the bearing portionv 21 in' the fulcrum recess 28 and the lower piece 23 is, in turn, held from swinging or rotating about the spike. Such holding of the lower piece from turning on the spike is accomplished by providing the laterally extending portion '30 thereof with downwardly deflected lugs 35 at the sides. there-:- of which are engageable "with the edge .ofithe:

base flange Mb at longitudinally spaced points thereof. The edge portion 30b lying between the downwardly deflected lugs 35 can be deflected upwardly, as shown in Figsp2 and 4, so as to extend in spaced overlying relation to the base flange M. This intermediate section 3% forms an arcuate strip-like portion which extends around and engages the inner edge of the stem portion 2 lb of the fastening memberfor preventing outward shifting of the lower piece 23 while the-engagement of the downturned lugs 35 with the edge of the base flange prevents rotation and.

inward shifting of the lower piece. i

In assembling the fastening above described, the upperand lower pieces '22 and 23 of the twopiececlamp are placed in superposed relation with "their openings substantially aligned with the opening [8 of the tie plate. The screw spike 2|, with the spring 24 thereon in surrounding relation'to the stem portion 2Ib, is inserted through the aligned openings and screwed into the tie I2. The "screw spike is initially screwed into the tie for-a distance which will cause the convolutions of the-spring 24 to becompressed to a closed or solid conditionalong the outer edgeof the spike, that-is-to say, at a point immediately above the fulcrum recess 28. Because of theinclinedpositionofthe upper-piece 23the convolutions of the spring at the opposite side of the spike will remain in spaced-apart relation.

The compressing of the spring; convolutions to such a solid-condition at the outer side of the spike formsastop by which the driving of the spike into the tie for the correct distance is assured during the assembly operation and overloading of the clamp orstripping of the spike from the tie opening is avoided. When the fastening haslb'een installed in this manner and a few trains have passed over the rail I4,Isome settling of ,the tie plate 13 will occur and thereafter a desired'small space will also exist between the adjacent. spring convolutions at the outer side of the spike. Sincelthe outer end of the upper piece 22.15 'fulcrumed, the maximum. swinging movement of. this piece willoccur at its inner end due to rising and falling of the rail during the pas 7 sage of trains thereover and this swinging move-' be secnithat an improved'rail fastening has been provided having a 1"elatively small number of parts adapted tcbe economically produced and V assembled-J 'It'will als'obe' seen that the upper piece of the two-piece clamp is rockable on a fulcrum formed by the lower piece and applies the -load of-the spring z l to the rail flange in a manner to effectively-'holdthe rail against the tie plate and, at the same-time, the lower piece applies the load-of the spring to the tie plate for holding the latter againstthe tie so that damage to the tie'b'y' pounding of the tie plate thereon will'be minimized. I

Figs.'l-5 and' 6 show a modified form of the above described rail fastening inwhich a conventionalitie plate 37 of a' different specific form is employed. "The tie pla-te here shown has an upstanding rail-gaugingshoulder 38 thereon and has an opening 39 therethrough which includes a rectangular extension alia intersecting the shoulder 33.x The fastening also includes a twoiece clamp comprising an upper piece 4% and a lower piece ll. The upper piece 40 is similar to the upper piece 22 above described but differs therefrom by reason-of the fact that it has a downwardly curved bearing portion 4911 at its inner end which bridges over the upstanding shoulder 38, as shown in Fig. 6.- I r The lower piece 4| is generally similar to the lower piece 23 above described but differs therefrom in that the intermediate section of the laterally extending portion 42 is deflected downwardly so as to form a depending rib or lug 43 which is engageable in the square extension portion 33a of the tie plateopeningSQ. ,The engagement of the depending'rib 43 in theexten sion opening 39a holds thelower piece 4i from turning about the stem of the fastenerwor screw spike 44. In other respects, this modified-form of rail fastening is the same as the "rail fastening shown in Figs, 1 and 2'and described above and functions in substantially the same manner. Figs. 8 and 9 show another modified form of the improved rail fastening and which is of substantially the same construction as the fastening shown in Figs. 5 and 6 but differs therefrom in that the square extension 45a of the tie plate opening 45 extends in a direction away from the rail and thelower piece 46 of the two-piece clamp has a dependinglugfl at the lower edge of the upright portion 46a thereof which engages 'in this extension opening for holding the. lower piece against turning about the screw spike 48. 1
