BENJAMIN WOLHAUPTER OF NEW ROCHELLE, YORK.

ANTIGREEPER.

Specification of Letters Patent.

. Patented May 11 1915.

Application filed Qebruary '25, 1911. Serial No. 610,908.

I To all whom it may concern Be it known that I, BENJAMIN WOLHAUP- TER, a citizen of the United States, residing at New Rochelle, in the county of Westchester and State of New York, have invented certai-n new and useful Improvements in Anticreepers, of which the following is a specification.

The present invention relates to certain new and useful improvements in rail anchors or anti-creeping devices for preventing the longitudinal movement of railway rails.

One of the objects of the invention is the provision of a device of this character which is simple and inexpensive in its construction and comprises few and small parts such as can be cheaply manufactured and assembled.

A further object of the invention is the provision of an anti-creeping device embodying novel features of construction whereby the action of the gripping or biting element is not affected by the-expansion and contraction of the rails due to changes in temperature.

A still further object of the invention is the provision of a device of this character which can be easily and quickly applied to or removed from any standard cross section of rail, and which will operate in'an eflective manner to prevent any longitudinal creeping thereof.

With these and other objects in view, the

invention consists in certain combinations and arrangements'of the parts as will more fully appear as the description proceeds, the novel features thereof being pointed out in theappended claims. While I do not wish to restrict myself to any particular form of the invention, yet several embodiments thereof are shown in the accompanyingdrawings, in which- Figure 1 is a transverse sectional view through a rail having the improved anticreeping device applied thereto. Fig. 2 is a sectional view on the line A-A of Fig. 1. Fig. 3 is a transverse sectional view through a rail having a modified form of the anticreeping device applied thereto. Fig. 4 is a sectional view on the line AA-of Fig. 3. Fig. 5 is a plan view of the rail engaging clip detached. Figs. (Mo 9 are detail views of a still further modification of the invention. Fig. 10 is a transverse sectional view of a rail showing a further modification of the anti-creeping device applied thereto. Fig. 11 is a plan view of the coast. ictr' on flange of the rail.

Corresponding and like parts are referred to in the following description and indicated in .all the views of the drawings by the same reference characters.

Referring to the drawings, the numeral 1 designates a rail which may be of any suitable cross section and which it is desired-to hold against any longitudinal creeping.

In the embodiment of the invention illustrated by Figs. 1 and 2 of the drawings, this rail rests upon a holding member or plate 2, the said plate being rigidly held upon the tie, and formed with a transverse slot 3 which is located under the base 'of the rail.

The 11111 engaging member A is in the form of a substantiallv U-shaped clip having an upper jaw 4: and a lower jaw 5 which diverge from each other. This 'cli isadapted to 'be ntted over an edge 0 The lower jaw 5 of the clip is received loosely within the slot 3 0i the holding member or plate 2, and is designed to abut against -one of the walls X of the slot. Theclip jaws may -be substantially square or angular in cross section, and loosely receive the flange of the rail when the clip is in an upright position. However, this clip is designed to be held yieldingly in a position cante'd from its wertical plane, as indicated more clearly in Fig. 2, so that the angular'edgeson the inner facesof the jaws will bite into the surfaces of 'the rail flange and provide a .positive holding engagement therewith. The means for -canting this rail-engaging clip from the vertical may be a spring arm 6, or its e uivalent, which as illustrated in Figs. 1 an 2, pro ects'laterally from the upper jaw FL of .the clip and is'curved downwardly so as to bear against the upper surface :of the base flange of the rail. This spring 6, or its equivalent, before being applied to the rail flange normally will take \the .position shown in dotted lines in F i 2, when being applied to the flange the clip is'tilted slightly and the spring-6 is forced into the position shown in "full lines. Hence, the spring action of this armwserves'to hold the clip tilted or canted so as tocause the anthe base gnlar edges of the jaws to securelfy a a grip the nge of the rail, and the upper cc of the lower jaw of the clip'may be-transversely serrated to provide the teeth 11 for producing a more positive engagement with the rail. Should there be any tendencyof the rail to creep in the direction of the arrow upon Fig. 2, the lower jaw 5 of the clip would engage the wall X of the slot 3 so as to hold the rail against such movement, and at the same time the action of the wall X of the slot against the clip would cause the clip to bite more strongly into the rail and i take a firmer hold thereon. In case the rail "ably crimped to provide an inclined portion.

moved longitudinally in the opposite direction, the clip would move therewith until the lower jaw thereof came into contact with the o' posite wall of the slot 3. The pressure 0 the said wall against the lower arm of the clip would then tend to reduce the biting action of the clip and to loosen it so that the" rail could move backward independently thereof. However, the spring canting arm 6'would always retain the clip in a positive engagement with the rail so that upon the reverse movement of the rail the clip would again be brought into contact with the wall X of theslot and act as modification is shown in which the spring arm 6 is applied to the loweraw 5 of the rail engaging clip A instead of to the upper j'aw. It will be obvious, however, that this spring arm 6 will bear against the bottom of the rail so as to cant the clip and cause it to bite into and positively grlp the flange of the rail as in the PIBVIOUS instance.

A further modification is shown inFigs. 6, 7, 8 and 9 in which thecanting means is not carried by the rail engaging member, but is separate and detachable therefrom. The body portion of the rail engaging member A is substantially as previously described, and a removable key 8 is designed to be inserted between the rail and one jaw of the'clip for holding the said clip in a canted position. 'lhis key 8 is shown as consisting of a s'prlng strip which is suit 8. When the spring strip is flattened out under pressure it can readily be inserted in position. This will be readily apparent by reference to Fig. 8, in which figure the rail engagin clip is shown in an upright position am the spring str1p flattened out for insertion between the upper jaw of the clip and the base flange of the rail. After the spring's trip has been inserted and released,

hold the rail engaging cli yieldingly in a canted position so that t e edges thereof the rail.

A further modification is shown in Figs. 10 and 11 in which the lower jaw, 5 of the rail engaging clip A is formed with an extension 5 which projects under the base of the rail and is provided at its extremity with a curved hook-arm 9 adapted to be sprung over the oppositev edge of the rail it again resumes the shape shown in Fig. 6, and the inclined portion 8 thereof serves to bite into and positively engage the flange of i base. In this embodiment the upper jaw 4 of the rail engaging clip-is formed with a spring cantmg arm 6 similar to that shown in Figs. 1 and 2. the jaws of the clip loosely receive the base flange of the rail, the device can be readily tilted into the position indicated by dotted lines on Fig. 10 when being applied" to the rail, and subsequently forced upwardly so as to cause the curved arm 9 to spring over the edge of the rail Figs. 12 and 13 illustrate a slight variation from the construction shown in Figs.

10 and 11, the extension 5 of the lower, jayv 5 projecting beyond the opposite edge of therail flange, where it is curled upwardly at 10, so as to have a spring engagement 'Owing to the fact that with the upper opposite edge of the rail base as in the previous instance.

In the modification shown in Figs; 14 and 15, the extension 5 of the lower jaw ofithe. clip is backturned at 11, the said backturned portion being provided upon its lower face with a depression 11 designed to engage the edge of the rail flange when the device is in operative posltion. 'Ihecanting means here shown consists of a V-shaped. spring member 12 which is inserted between the extension 5 and the base of the rail. Should the rail have a tendency to creep, the lower jaw of the clip becomes engaged by the said tie and the clip would then operate as has been previously described to force the same into a. firmer engagement with the rail so as to 1 1151 this form of the invention, that is, the one shown in Figs. 14 and grip the rail and prevent longitudinal movement thereof. In

15 of the drawings, it will be observed that the backturned-end 11 of the clip bar is so disposed as to provide between the same and the extension 5 a pocket 13 of suflicient depth laterally and vertically to readily ad- 'mit of the clip being placed over and disen- When the gaged from the rail flanges. v

bar can be moved laterally upon the- Y rall flanges to readily engage and disengage My invention is susceptible to many other variations and modifications. which can be made without departing in any manner from the spirit thereof, and I do not restrict myself to the specific embodiments illustrated by the accompanying drawings and described herein.
