RAIL-ANCHOR.

Specification of Letters Patent.

Patented Jan. 28, 1919.

Application flied my 15, 1916. Serial No. 97,589.

To all whom it may concern Be it known that I,WILL1AM M. MITCHELL, a citizen of the ,United States, and a resident of Louisville, in the county of Jefl'erson and- State of Kentucky, have invented certain new and useful Improvements in Rail-Anchors, of which I do declare the following to be a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

The present invention has relation to rail anchors or anti-creepers designed to prevent the creeping of railway rails along the tracks. An example of. the type of rail anchor to which my invention more particularly relates is set forth in Patent e present invention consists in the features of improvement hereinafter described, illustrated in the accompanying drawings and particularly pointed out in the claims at the end of this specification.

Figure 1 is a lan view of my improved rail anchor showing also a portion of a rail to which the anchor is connected and a portion of a tie on which the rail is-mounted. Fig. 2 is a view in vertical cross section on line 2-2of Fig. 1. Fig. 3 is a view in side elevation of the rail anchor. Fig. 4: is a view in vertical section on line 4-4 of Fig. 2. Fig. 5 is a plan view similar to Fig. 1 but showing a slightly modified form of the invention. Fig. 6 is a view in transverse section on line 6-6 of Fig. 5. Figs. 7 and 8 are views similar to Figs. 3 and 4 but showing the modified form of the invention illustrated on Sheet 2 of the drawin s. Fig. 9 is a detail inverted plan view of t e movable j aw of the anchor.

A designates a railway rail and B denotes one of the ties on which the rail is mounted. The body 0 of the anchor extends beneath and bears against the bottom of the railway rail and is provided at one end with a rigid jaw 0 adapted to engage the base flange a of the railway rail A. The opposite end of the body member C of the anchor extends beyond the base flange a of the rail A and is provided with a projecting portion having an abutment C adapted to bear against the side of the railway tie B. In the thickened end portion of the anchor C adjacent the abutment C is formed a dovetail groove 0 adapted to receive a correspondingly dovetailed rib d of the movable jaw D of the anchor. This movable jaw D extends over the raised portions 0" and c of the end ortion of the anchor C and has an inward y projecting part provided with an inclined face d adapted to bear against the upper surface of the base flange a of the rail. The upper face of the raised portion 0 of the anchor is formed with a series of alternating ribs and intermediate spaces 0 and c and the under side of the outer portion of the movable jaw D is formed with corresponding ribs and spaces d and d In Patent No. 1,184,47 8, hereinbefore referred to, the movable jaw is provided with serrations or teeth upon its under side adapted to engage with corresponding serrations or teeth upon the upper surface of the outer end portion of the rail anchor but it will be noted that in the present construction, the ribs and spaces 0 and c and the corresponding ribs and spaces upon the under side of the movable jaw are arranged at a distance apart and are comparatively broad and shallow, the )urpose of this construction being to enab e the movable jaw to more readily pass over the ribs and spaces until the jaw has been forced to the position at which it will firmlyengage the base flange a of the rail A.

The upper surface of the movable jaw D. is formed with strengthening ribs d and between these raised ribs extends a rib d", the purpose of this rib being to strengthen the jaw and enable it to resist the blows of the hammer by which the jaw D is forced to firm engagement with the base flange a. of the rail.

The groove 0 and the tongue or rib d are inclined downwardly and inwardly toward the base flange of the rail A, the purpose of this being to insure that as the movable jaw is forced to position for use,-it will move downwardly and inwardly toward the base of the rail and will thus more effectively grip the flange a of the rail as the jaw D is driven to its seat.

In applying my im roved rail anchor to a rail, the body portion of the anchor is assed beneath the base of the rail and the fixed jaw C is engaged with the base flan e a of the rail in the usual manner, the b0 y C of the anchor being lifted into bearing with the under side of the rail base; after which the tongue or rib d of the movable aw is inserted into the groove c and the aw D is then driven toward the abutment O by a hammer until the inwardly projecting portion of the jaw firmly engages and gri s the flange a of the ra11 A. As the jaw is thus forced to posltlon to firmly en age the rail the ribs d on the under sife of the jaw ride over the shallow r1bs 0 on the upper surface of the end of the anchor C but as the jaw reaches its final position, the interlocking of the r1bs a and (1 will insure the retention of the movable jaw. against danger of accidental displace-.

v D has it outer portion formed with a depending flange d upon the under surface of which are formedthe ribs d and spaces d that interlock with the correspondin ribs 0 and spaces a at the end of the ram anchor. So, also, in this form of the invention, the inner portion of the movable jaw D is provided with a depending flange d which is adapted, when the jaw is forced firmly to position for use, to engage the edge of the base flan e a of the rail while the inner portion d o the jaw bears against the upper surface of the base flange a. In order to permit the groove 0 to be formed below the line of the upper surface of the body portion C of the anchor, the adjacent end portion of the anchor is formed with a downwardly'extending body of metal 0 as clearly shown in Figs. 6, 7 and 8 of the drawings.

By locating the groove 0 in the body member of the anchor and by forming the tongue or rib d upon the movable jaw, the parts can be more readily cast than where the groove is formed in the movable jaw and the tongue or rib on the body member,

as in the construction set forth in my hereinbef ore mentioned patent.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A rail anchor comprising a body member adapted to extend beneath the rail base and having means at one end for engaging one ofthe base flanges, and a forwardly projecting tie engaging abutment adjacent --1ts opposlte end, the said opposite end of said membenbeing arranged to project beyond the ad acent base flange of the rail and havmg an upwardly opening, dovetail maasae groove, and a wedge member having a depending,'relatively narrow dovetail rib on its under side arranged to enter sald groove,

' said rib and said groove being arranged outside the adjacent base flange of the rail and being inclined relatively thereto, and said members having portions inside of said rib and groove arranged to grip the ad acent base flange of the rail between them.

2. A rail anchor comprising a body member adapted to extend beneath the rail base and having a jaw at one end for engaging one of the base flanges, the opposite en 0 said member being arranged to project beyond' the other base flange, and=having an.

upwardly facing dovetail groove, and a wedge member having a depending dovetail rib on its under side arranged to enter said groove said rib and and said members having portions inside of said rib and groove for gripping the rail flange between them, and said members also havmg cooperating locking surfaces outside of sai rib and groove.

3. A rail anchor com rising a body member adapted to extend eneat the rail base and having means at one end for engaging one of the base flanges, the opposite end of said member being arranged to project beyond the other base flange and having .a dovetail groove, a wedge member above the projecting end portion of said body member and having a depending dovetail rib on its under side arranged to enter saidvgroove, said rib and said groove being arranged'outside of the adjacent base flange of the rail and being downwardly and inwardly inclined relatively thereto, and said members being arranged to grip the adjacent base flange of the rail between them.

oove being inclined,

4.. A rail anchor com risin a body member adapted to extend eneat the rail base and havinga'jaw at one end for engaging one of the base flanges, the opposite end 0 said member being arranged to project beyond the other base flange and having a thickened portion proj ectin upwardly above the upper face of said body member, said thickened portion being provided with an upwardly opening, dovetail groove, and a wedge member having a depending dovetail rib arranged to enter sald groove, and a portion projecting inwardly therefrom arranged to overlie the adjacent base flange of the rail, said rib and groove being inlit clined, and the portions of said members inv of the body member.

vided upon its under side with a de ending rib to engage with the groove of the body member and being provided at its outer side with a depending flange extending below the raised portion of the adjacent outer end of the body member and adapted to engage with a horizontally extending end portion 6. A rail anchor comp-rising a body member adapted to extend beneath the rail base and to engage the flanges thereof, said body member being provided at one end with -a transverse groove, and a transversely movable jaw arranged above said body member and provided upon its under side with a depending rib to enter the groove of the body member, said jaw having an inwardly projecting portion to engage the top of the base flange of the ra1l and having adjacent said inwardly projecting portion a depending flange to engage the outer edge of the base flange of the rail.

7. A rail anchor comprising a body member adapted to extend beneath the rail base and having means at one end for engaging one of the base flanges, said member having a thickened opposite end portion provided with a dovetail groove, and a wedge member having a depending dovetail rib arranged to engage said groove and a portion pro ecting inwardly from said rib arranged to overlie the adjacent base flange of the rail, said rib and groove being inclined and said members having portions inside of said rib and groove for gripping the adjacent base flange of the rail and said members having engaging portions outside of said rib and groove having shallow, rounded,
