This invention relates to fastenings or anchors for railway rails andaims to provide novel means for this purpose which is very simple, economical and efficient; ' . ~ 2 The tie plate II, as shown in Figs. 1 and 3, is a substantially ?at metal plate having one or more upstanding transverse ribs or shoulders I9 for co operation with the ?ange I4 for gaging or locating the rail. A desired number of the ‘openings Ho and 18a for the cut spikes I1 and I8 are pro . Another object of my invention is to provide an improved fastening of this character by which vided in the plate at suitably located points. a rail can be secured to a tie or other support When the ribs I9 are provided on the tie plate the opening I8a may extend therethrough as shown Still another object of this invention is to pro in Figs. 1 and 3. The openings I‘Ia and I8a are vide an improved rail fastening involving the use 10 preferably somewhat larger in size than the stems of a curved spike or clamp which can be very of the spikes II and IB so that the tie plate can and effectively held against longitudinal creeping. economically manufactured and readily applied have limited lateral movements. .

In the embodiment of the invention illustrated in Figs. land 3 I show a rail‘ I0 supported on a portion 2| of thetie plate so that when the clamp 40 or spike I2 is driven or installed in such openings it will lie immediately adjacent the side face 22 of the tie I6 as shown in the drawing. In this position the member I2 serves as an anti-creeper as well as a rail clamp and effectively prevents plate I I and clampingly secured thereto by means longitudinal creeping of the rail I0. cured to the tie I6 by cut spikes I1 and I8 driven into the tie through suitable openings I‘Ia and I8a provided in the plate. The spikes I‘! also offset relation to the stem 26 and is adapted to, engage the rail ?ange I4 in overlying relation engage the rail ?ange I4 along opposite edges substantially straight portion 26a depending from The fastener I2, which is herein referred to as of one or more of my novel spikes or clamps I2. 45 a spike or clamp, comprises a curved stem 26 The rail III is of a conventional form having a having fastening or holding elements 2'! and 28 head I3 and a base ?ange I4. In the form of the atv opposite ends thereof. The fastening element invention here illustrated, the plate II is atie 21 is here shown as a head which may be of a plate and is shown resting on the upper face I5 shape similar tothat provided on conventional of a wood cross-tie I6. The tie plate II is se 50 cut spikes, that‘is to say, it projects laterally in thereof. Y - thereto. The stem 26 comprises a relatively short 3 2,408,628 the head 21 and which may be of a quadrangular cross-sectional shape and a curved or bowed por 4 extends only part way along one side of such plate and has only one pair of the openings 23 and 24 for the spike or clamp l2. Fig. 4 shows a rail fastening embodying this modi?ed form of tie tion 26b. The curved stem portion 28b is tapered or relatively reduced in thickness and provides the clamp with a substantially flat reversely 5 plate and from this view it will be seen that the curved tail portion. The holding element 28 pro tie plate and clamp I 2 are used in a similar man vided 0n the end of the curved stem portion 26b is in the form of a hook adapted for anchoring engagement with the tie plate I I when the curved stem portion is sprung upwardly into the opening 24 of the tie plate as hereinafter explained. At a point adjacent the junction of the straight stem portion 26a with the curved stem portion 26b -I ' provide the clamp with a lateral projection or shoulder 29 which engages the under surface of the tie plate H and forms a fulcrum upon which the spike rocks when being driven or installed in the tie plate. In Fig. 2 I have shown the clamp l2 in full lines in its installed or driven position and have - also shown the same clamp in construction lines in its partially driven position. In such partially driven position, I have shown the clamp [2 after its curved stem portion or tail section 2% has been passed downwardly through the opening 2.3 of the tie plate and just prior to the engagement of the lateral shoulder 29 beneath the tie plate‘ i 5. By means of a suitable tool (not shown) the curved stern portion or tail section 26b is lifted o-r sprung upwardly toward the tie plate so as to ner and serve a similar purpose to that explained above for the tie plate II and the clamps l2 em ployed therewith. Fig. 5 shows how two tie plat/es having the plan shape of the plate illustrated in Fig, 4 can be cut from plate stock 35 so as to substantially elimi nate waste. It will be noted that the tie plate 25 has a wide end 25a and a relatively narrower end 252) and that its straight edge portions 35 and 31 along one side thereof extend toward each other for a portion only of the length of the tie plate and have their adjacent ends connected by the relatively inclined edge portion 38. When the straight edge portions 36 and 31 are made of sub stantially equal lengths, as shown in the drawing, two of the tie plates 25 can be out from a single piece of plate stock 35 as indicated in Fig. ‘5 and the two resulting tie plates will be of sub stantially identical shape. From the foregoing description and the ac companying drawing it will now be readily under stood that I have provided an improved rail fas tening or anchoring means by which a rail can be securely and resiliently clamped in proper po- ' move the holding element or hook 28 through the opening 24. As the hook 28 moves upwardly through the opening 213 the resiliency of the clamp effectively held against longitudinal creeping. It will cause the hook to snap to its full line posi tion in which it cooperates with the tie plate in form of tie plate usable in my improved rail fastening and which can be cut from plate stock anchoring the outer end of the clamp 12 thereto. Such upward movement and springing of the curved stem portion 281) causes the clamp to rock or fulcrum on the shoulder 29 thereby swinging the head 27 laterally and downwardly to its full 40 line position in overlying clamping engagement sition on a rail-supporting plate and will be will be seen also that I have provided a novel substantially without waste. Likewise it will be seen that I have provided a novel form of rail clamp or spike which can be very economically manufactured and can be easily installed or driven in forming my improved rail fastening. While I have illustrated and described my im proved rail fastening and the features and ele with the rail ?ange I .4 as shown in fulllines in the drawing, The curved stem portion 25b of the ments thereof in more or less detail it will be clamp i2 is resilient in character, as above indi understood, of course, that I do not wish to be 45 cated, and when the clamp has been driven or in correspondingly limited but regard my invention stalled as above explained the head 27 will exert as including all changes and modi?cations coming a strong but somewhat yielding clamping force within the scope of the appended claims. on the rail and will securely hold the rail to the tie Having thus described my invention, I claim: plate H so as to retain the rail in proper posi 1.
