Specification of Letters Patent.

Serial No. 725,976. I

To all whom may concern Be it known that l, PHILIP W Moore, a citizen of the United States, residing at Evanston, in the county of Cook and State of Illinois, have invented a cert-ainnew and useful Improvement in Anticreepers for Rails, of which the following is a full, clear, concise, and exact description, reference be ing had to the accompanying drawings, forming a part of this specification.

My invention relates to anti-creepers for rails.

The object of the invention. is to provide improved means for automatically locking the parts of the anti-creeper to each other to prevent loosening and possible disengagement from the rail.

In order to better explain the features of the invention I have illustrated two cmbodi ments thereof. The invention is not limited to these embodiments, however.

In the drawings: Figure 1 is an elevation of one form of anti creeper, a portion of the rail being shown in sectional elevation. Fig. 2 is a top plan view thereof. with the rail and cross-tie indicated in dotted out-line. Fig. 3 is a perspective view of one of the members of the anti-creeper, and Fig. i is a perspective view of the other member. Fig. is an elevation of a second form of anti creeper shown as applied to the rail. Fig. (i is a top plan view thereof. Figs. 7 and 8 are perspective views of the two members which make up the anti-creeper.

The anti-creeper is made up of two parts in both forms of device illustrated, although a greater number of parts may, of course. be employed. These parts are made preferably of malleable metal. The larger of the two parts .1, may be called the'clip. The smaller of. the two parts 2. may be called the mate. The clip is provided withjaw 3, adapted to fit over and grip one side of the base of the rail 4;, said jaw being suitably reinforced by flanges 5. The mate is pro vided with a similar jaw 6, which is suitably reinforced by flanges 7. The clip is provided with a slot or recess in its upper face,

one side wall 8 of which is slightly undercut as shown particularly in Figs. 1 and 3, and acts as an engaging face for a corresponding face 9, on the mate, said latter face being one of the sides of a rib 10, which rib is Patented Jan. 13., 119147..

adapted to be received within the slot in theclip. I

As shown in Fig. the engaging faces of the clip and the mate are not exactly parallel with the longitudinal axis of the rail, but are arranged at an angle thereto. in assembling the rail anchor, the clip is applied to the rail shown in said figure, with the downwardly. extending tie abutting flange 11. bearing against the side of the cross-tie 12. The mate is applied to the rail at the end of the clip away from the cross tie and is then driven toward the tie to ap proximately the position shown in Fig; 2, the engaging faces 8 and 9 acting as wedging surfaces which draw the jaws 3 and 6 toward. each other into firm engagement with the rail base. As long as the rail tends to creep in the direction of the arrow in Fig. 2, the tendency of the mate is to advance with the rail, and thereby increase the wedging engagement of the parts. any advance of the clip being prevented by the cross-t-ie. If the rail should move in the reverse direction, however, due to contraction in cold weather or due to a reversal of traffic, for example, the effectiveness of the engagement of the clip with the mate might be de creased under certain conditions. To prevent a rearward movement of the mate and the consequent loosening of the engagement of the parts. I provide a locking'tnngue 13. which extends rearwardly from the clip in substantially a vertical plane. The rib it) on the mate does not extend rearwardly the entire length thereof but terminates in a locking face 14. as shown in Fig. 4. Adjacent to this locking face and slightly till the rear thereof, a cam surface 15 is prov ded, which engages the tongue 13 when the mate is being driven forward, and thereby defleets the same and bends it over the locking face 14-. The locking tongneand in fact the entire clip being made of malleable metal, this bending may take place without danger of breaking off the tongue. Accordingly. said locking tongue has a positive locking engagement with the corner or edge at the side of said locking face, thereby preventing movement of either of themembers of the anti-creeper in a direction to decrease their wedging engagement. It will be seen that the locking tongue 13 is relatively short and is deflected into a notch formed in the adapted to be received within said slot, said mat at a point between the front and the rear walls of said mate, and hence when deflected does not pro ect rearwardly from the anti-en per as a Whole.

in, the form of anti-creepers shown in 5. 5, '7 and S, the main elements of the mice are substantially the same as those previously described and the same reference I characters have been applied thereto. The

looking tongue 16 is inclined in a reverse direction from that previously illustrated, however, and when engaged by the cam sun face 17 is deflected across thelocking face 18, which constitutes the rear of the diagonal rib or Wall 10. The tongue 16, is deflected away from the jar; 3, instead of toward the same, as in the first case illustrated. Said tongue does not project to the rear of the anti-creeper, however, but is protected in this form oi? device also.

ln both devices, the mate is driven into the clip as far as circumstances will permit, the locking tongue serving to lock th parts in I one of a number of possible relative potions. Furthermore, the effective opera tion of the lock is not dependent on any accurate predetermined degree of adjustment of the parts, said loci: permits considerable latitude in this regard. it is apparent that various forms of anticreeper may be devised and that various changes may be made in the details of those forms described herein Without departing from the spirit of the invention, as expressed in the appended claims.

lVhat l. claim as new and'desire to secure by Letters Patent of the United States is:

1. in an antirreeping device, a plurality of engaging members, rail gripping means on two of said members, certain of said members being relatively movable to decrease the trans verse distance between said rail gripping means, a singlelocking tongue projecting from the rear 01'' one of saidmembers, and means toward the rear of the other of said members for automatically deflecting said tongue against a vertical locking shoulder thereon. r

2. A rail anchor comprising t v0 rail grip ping members, one of said members having a diagonally arranged slot, the other of said members having a diagonally arranged rib l first member being provided with a rearwardly projecting tongue adapted to be deflected into a notch in said rib when said members are moved relatively.

3. An anti-creeper for rails comprising two members each having rail gripping jaws,

one of said members having a channel arranged nearly parallel to the rail base, the other of said members having a rib adapted to be received in said channel, said rib having a notch therein intermediate its ends, said other member having a projecting tongue adapted to be deflected into said notch.

4:, A rail anchor comprising aplurality of members having interlocking Wedging engagement beneath the rail base, said Wedgi11g engagement being effected by a diagonally arranged rub on one of said members which is received in i i-corresponding slot in the other of said members, said rib having an intermediate notch therein and having.

also a cam surface, said other member having a short tongue projecting from the rear thereof, whereby may be deflected by said cam surface into saidinotch when said parts are being assembled, whereby said tongue locks said parts together without projecting from the rear thereof. 7

5. An anticreeper for rails comprising a clip and a mate, said clip having a rail e'n gaging jaw, a tie abutting flange and a diagonally arranged slot, said-mate having a rail engaging jaw and a diagonally arranged rib adapted to slide within said slot said rib being shorter than said mate, a shoulder at the rear of said rib, said inate' liaving a notch adjacent to said shoulder, one of the walls of said notch forming a cam surface, and a tongue on said clip projecting rearwardly therefrom, substantially in line with one wall of said slot, whereby said tongue is engaged by said cam surface andde'flected over said shoulder when the parts are being assembled.
