Specification of Letters Patent.

Patented dan. 4t, 15916..

Continuation in part of application Serial No. 825,244, filed March 17, 1914. This application filed August 19, 1915. Serial No. 46,258.

To all whom it may concern:

Be it known that I, LEWIS O. HENGGI, a citizen ofthe United States, and a resident of Oakmont, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Creep-Checks; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention pertains to creep-cheeks, that is to say devices for preventing railroad rails from creeping longitudinally of the tracks.

It is one of the objects of my invention to produce a creep-check which willbe easy of manufacture and which will retain its position onthe rail and perform its functions, regardless of whether changes, vibration and jarring of the rails, etc.

It is another object of vmy invention to provide a creep-check in whichthe work required in applying it to a rail, or removing it from arail, will be al minimum.

Other and further objects of the invention will appear from the following specification, taken in connection with the appended claims.

In order that my invention may be fully understood, I have described, by way of eX- ample, one embodiment thereof in the following specification, and shown the same in the accompanying drawing, in which: Y

Figure 1. is a side elevation of a creepcheck constructed in accordance with my invention; Fig. 2 is a plan of the same; Fig. 3 is an end view of the creep-check, showing the same applied to a rail; Fig. 4 is a side elevation showing, in broken lines, one step in applying the creep-check to a rail base, and, in full lines, a succeeding step; and.Fig. 5 is a side elevation showing the creep-check in place on the rail base.

. I i'ke reference characters refer to like parts throughout the following specification and the several figures ofthe drawing.

The form of creep-check shown in the drawing consists of a steel bar, rectangular in cross-section, the ends of whichare bent over to form hook-shaped'

jaws

10 and 11 respectively. The jaw 11 is -substantially twice as long as the jaw 10, and its open portion 12 is somewhat wider than that of the stantially the same angle as the top surfaces of the rail base approach each other. That is to say, when the creep-check is to be used with a 13 degree rail base, the

jaw surfaces

13 and 14 approach each other at substantially 174 degrees. and nearer the jaw 10 than the jaw 11, the body portion of the creep-check is bent inwardly so as to form a seat 15. The proportions andshape are such that the seat 15 will be within the line which would be formed by the bottom surface of the rail base, if the top surfaces of the rail base be made 'to coincide with the

jaw surfaces

13 and 14. This will be readily understood from Fig. 1, in which a rail base is indicated in dotted lines, 16 and 17 designatingrigh-t and left hand top surfaces respectively, and 18 designating the bottom surface. It will be seen that with the jaw surfaces 13 yand 14 coinciding with the

rail base surfaces

16 and 17, the creep-check f seat 15 is within the line formed by the rail base bottom surface 18. The seat 15 is also substantially parallel with the line formedby the surface 18. In other words, for a 13 degree rail, the seat 15 is disposed at an angle of substantially 13 degrees with 5respect to the

jaw surfaces

13 and 14.

In applyingA the creep-check to arail, 'the end aw 11 is first hooked over the rail base, so that its end engages with the top of one of the upper base surfaces, in the drawing the surface 16 (broken lines Fig. 4). The creep-check is then swung upwardly until its Intermediate its ends,

seat 15 engages against the rail surface 18 I and the end of the jaw 10 engages the bottom part of the rail surface 17 (full lines Fig. 4). It will be seen that the jaw 10 cannot be moved, from the position shown in Fig. 4, farther up the rail base without distortion of the creep-check.

The. operation of applying the creepcheck is completed yby driving the jaw 10 upward on the rail base by means of a sledge hammer or the like, the finalv position of the creep-check being as shown' in Fig. 5. The broken lines in Fig. 5 indicate the original shape of the creep-check.; and it will be seen that, in driving the jaw 10 onto the rail base, the metal of the creepcheck has been-strained apart. The tendency of the creep-check to return to its original shape results-in an extremely strong gripping action on the rail base, such gripping action being more than sufficient to hold thecreep-check inv position in spite of any vibration to which the rail may be sub- 110 jected, and in spite of weather changes or the like.

The-creep-check is placed in position so as to abut against a tie, designated 19 in Fig. 3, at that side of the tie which is opposed t0 the direction in which the rail will tend to creep. ,By its engagement with the tie, the creep-check prevents any longitudinal movement of the rail.

The creep-check described above is extremely simple and easy of manufacture. It can be applied to a rail base in less than a minute, and kcan be removed equally quickly by striking the end l1 of the creepcheck with a sledge hammer or the like. After having been thus removed, the creepcheok can be used over'again,if desired. When once applied to a rail base, there is no liability of the creep-check to become loose or to shift endwise on the rail.

IVhile I have described in the foregoing speciiication'one form of creep-check embodying my invention, I wish it understood that changes may be made in the details thereof without exceeding the scope of the invention as defined in the appended claims.

vWhat I claim as new and desire to secure y by Letters Patent is 1. In an anti-Creeper, a body having a portion disposedso as to bear against the bottom of the rail base, and a pair of terminal jaws disposed so as to rigidly engage the top of the rail base when said body is forcibly moved transversely of said rail base, and thereby retain the anti-Creeper in position on the rail base. y

' 2. An anti-Creeper for rai-ls including a bowed body member having an intermediate bearing projection engageable with lthe bottom face of a rail base, and terminal gripping jaws formed on the body member for securing said anti-Creeper to the rail base, said body member being adapt-ed to be moved transversely on the rail base after being applied thereto, whereby the jaws may be tightened or loosened on the rail base.

3. An anti-Creeper formed from a single bar of metal bent to form an upwardly bowed body portion and terminal jaws of unequal length. f

4. Anne-piece creep-check comprising a body having portions for engaging and gripping the rail base, thereby to secure the creep-check on the' rail base, L'said portions being arranged and disposed so as to permit of distortion of the creep-check within its elastic limit to efectsuch engagement, one of said portions being extended outwardly to form an interior clearance, thereby to permit the creep-check to be first placed in position on said rail base and then distorted so as to effect such gripping engagement. y

5. A creep-check comprising a member having the ends thereof bent to form a body portion and end jaws for engaging the top surfaces of the rail base on either side of the rail thereby to secure the creep-check to the rail base, said body portion being formed with a seat for engaging against the bottom surface of the rail base, and said seat being so disposed with relation to said jaws as to necessitate distortion of the creepcheck to allow said engagement.

6. A creep-check comprising a member formed intermediate its ends with a seat portion for engaging the bottom surface of the rail base andbent to form end jaws. for engaging the top surfaces of the rail base on either side of the rail thereby to secure the creep-check to the rail base, one of said jaws being extended outwardly to form an interior clearance t0 permit the preliminary positioning of said member on the rail base, .and said seat being 4so dlsposed wlth relation to said jaws as to necessitatedistortion of the creep check to allow said engagement.

7. A creep-check comprising 'a member having the ends thereof bent to form a body portion and end jaws for engaging the top surfaces of the rail base thereby to secure the creep-check to the rail base, one of said jaws being-extended outwardly to provide an interior clearance to permit the preliminary positioning 0f the member on said rail base. said body portion being formed, intermediate itsends and at the side of its center remote from said extended jaw, with a seat for engaging against the bottom surfaceof the rail base, and said jaws and seat being disposed so as to necessitate distortion of the creep checkto allow said engagement.

In testimony whereof, I the said LEWIS O. HENGGI have hereunto set my hand.
