1917. Serial No. 149,259.

To all whom it may concern:

Be it known that I, Ronnn'r E. BnLKNAr, a citizen ot the United States, residing at Chicago. in the county of Cook and State of Illinois. have invented new and useful Improvements in Rail-Anchors, of which the following a specification.

This invention relates to rail anchors or anti-Creepers for rails.

This application is a division of an appli; cation filed by me .lune Q3. 1913. Serial No. 775,172. which resulted in Patent No. 1,228,- 171, dated May Q9. 1917.

One ot the objects ot' this invention is to provide a simple and reliable anchor which may be readily applied to the rails.

Another object is to provide an improved rail anchor having simple, etlicient and easily applied means t'or retaining it in position on the, rail.

()ther objects and advantages of the invention will appear in the following description and claims.

ln the drawing:

Figure 1 is an end view of one form of the rail anchor ot my invention in place. Fig. 2 is a side elevation of the anchor of Fig. 1. Fig. 3 is an end view ot' another form ol: anchor embodying my invention. Fig. 4 is onel of the details of the anchor of Fig. 3. Fig. 5 is an end view of still another torni of anchor in accordance with my invention. Fig. (3 is a section on the line 6-6 of Fig. 5

The anchor comprises a pair ot jaws adapted to engage the base flange ot' the rail and to increasingly grip the base when the anchor meets the resistance of a tie as the rail tends to creep. In order to retain the jaws in gripping position and to prevent. displacement by the jar of passing loads and retrograde movement of the rail.,- retaining means engaging an edge of the rail base to oppose an]y displacing movementare provided. In order to facilitate the application of the device the retaining elements are adapted to be positioned in a direction transverse to the length ot' the 'ail.

Referring to the construction of Figs. 1 and 2, the rail A is shown resting upon a tie B, against which a portion of the anchor impinges to prevent the rail from creeping. The anchor is shown as provided with av downwardly extending foot or leg 19, which will abut against the tie some distance below the rail as shown in Fig. 9 The rail is gripped on one side between an upper '2O and a lower jaw Q3, the disposition of the jaws and the construction of the foot being such that the jaws are normally biased to grip the rail base. lVhcn the rail starts to creep so that the leg 19 begins to be forced against the tie. the anchor is rocked or tilted in a substantially vertical plane and the aws grip the base more firmly. The anchor then being in etlect secured to the rail and abutting a stationary tie acts to prevent the rail from creeping. 1n order to more positively hold the anchor in place, especially when the leg 19 is not against a tie. and to provide for additional gripping action. a second jaw or clip 91 is made to embrace or overlie the opposite edge of the rail base. This supplemental retaining member or jaw has an opening fitting over a square projection 19, extending from thev anchor body 1n a direction transverse to the length of the rail as clearly indicated in Figs. 1 and 2. The retaining member or supplemental jaw is thus placed in position by being applied to the body extension in a direction transverse to the length of the rail. This method of application is exceedingly simpl t and requires little space for its easy accomplishment. A pin 22 extending through an opening in the projection 19 serves to prevent the jaw 21 from being jai-red loose and holds it to the rail.

ln Fig. 3 is illustrated another form of anchor having a depending foot or leg 7 for abutting the tic as previously described. The anchor is also provided with an upper jaw 8 and a lower jaw 10 for gripping th top and bottom respectively ot` the rail base. There is a member or projection 7 extending from the anchor body transversely to the length of the rail to a point beyond the base as shown in Fig. 3. The jaw S has an extension or provided with a member 8a which extends through'an opening 7 in the rail web. The projection 7 extends through ai; opening in a rod 9 (shown in deta:l in Fig. el) which is applied thereto transversely to the length of the rail whose upper end is passed through the same opening Z) in the rail web as the extension S, 1n order to hold these parts securely to the rail the extension Sa is bent downwardly and the upper end ot the rod 9 is split and bent outwardly, as shown in the figures. In order .in a direction transverse to the length of the rail when being applied to the rail and to be secured against displacement. Each section has an extension 13 forming a jaw and the right hand section of Fig. 5 has a horizontal extension M on which is formed a bearing surface or jaw 14n. This extension which is a little more than a semi-circle in cross-section is adapted to tit in a horizontal socket formed in an extension 12a of the left hand section. rhis latter section is also provided near its lower end with a "l" -shaped socket 12b adapted to receive an extension l2 of the right hand section or" the anticreeper, such extension being also substantialli,v 'lf-shaped in cross-section as illustrated in Fig. S. This extension is adapted to slide in said slot and in order that the parts may be held together when in home position with a. sufficient force to prevent displacement, 1

rovide snch extension with a small projecting point 12d adapted to engage a depression i or cavity 12e in the base of the slot. e What ciairn is:

l. A. rail anchor comprising a body having a pair of jaws to grip the rail base between them and a tie abutting portion adapted to cause the jaws to tilt in a substantially vertical plane to increasingly grip the base when the rail tends to creep, and a retaining member for,` engaging an edge of the rail and adapted to be positioned upon said body by application thereto transverse to the length of the rail.

2. An anti-creeperfor rails comprising a body made in two sections arranged to slide upon each other and having means for engagement against displacement, each section having an extension forming in connection with the body a jaw to receive the rail-base, said body being adapted to tilt to cause the jaws to grip the rail-base.

A rail anchor comprising a body having a pair or" jaws to grip the rail base between them and a tie abutting portion adapted to canse the jaws to increasingly grip the base when the rail -tends to creep, and a retaining member applied to said body in a direction transverse to the length of the rail and adapted to embrace one edge of the rail base to prevent lateral displacement, of the body.

et. A rail anchor comprising a body having a tie abutting extension and a pair of jaws embracing one edge of the rail base and adapted to' increasingly grip the base when the extension abut-s a tie as the rail tends to creep, and a retaining jaw adapted to be associated with said body and embrace the oppositie edge of the rail base by being applied transversely-to the length of the rail.

5. A, rail anchor comprising a bodyv portion having a pair of jaws embracing one side of the base flange of a rail and normally biased to grip the top and bottom of the base flange, a member extending from the body beneath and transversely of the rail base. and means applied to said member in a direction transverse to the length of the rail for engaging the edge of the rail base opposite the jaws to hold the anchor in place.

6. A rail anchor comprising a pair of jaws adapted to embrace one edge of the base of a rail and when tilted in a vertical plane to increasingly grip the rail base to prevent creepage, a depending leg adapted to abut a tic to tilt the jaws as the rail tends tocreep, an extension from the jaws projecting therefrom in a direction transverse to the length of the rail, and a retaining member adapted to be applied to said extension in a direction transverse to the length of the rail to embrace the opposite edge of the rail base to prevent displacement of the jaws.

7. A rail anchor comprising a pair of jaws adapted to embrace the base of a rail and when tilted to increasingly grip the base to prevent creepage, a depending leg adapted to abut a tie to tilt the jaws when the rail tends to creep, an extension projecting from the jaws in a direction transverse to the length of the rail, a retaining' member adapted to be applied to said extension in a direction transverse to the length of the rail and to embrace an edge of the rail base to prevent displacement of the jaws, and

means to lock said retaining member in place.

8. A rail anchor comprising a body hav ing a pair of jaws adapted to grip the rail base between them and a tie abutting leg adapted to cause the jaws to increasingly grip the base whenthe rail tends to creep, and a retaining member adapted to be positioned uponsaid body by application thereto transverse to the length of the rail and engaging an edge of the rail to oppose the tendency of the jaws to spring laterally from the rail base when the leg engaging a tie places the jaws under pressure.

In wit-ness whereof, I have hereunto subscribed my name.
