P. W. MOORE RAIL ANCHOR Filed July 21 1921 Patented Dec. 4, 1923..

UNITED. STATES PHILIP W. MOORE, OF HUBBARD WOODS, ILLINOIS, ASSIGNOR TO, THE P. & M. COM- PANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

RAIL ANCHOR.

Application filed July 21,

To all whom it may concern:

Be it known that I, PHILIP W. Moons, a citizen of the United States, residing at Hubbard Woods, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Rail Anchors, of which the following is a specification.

My invention relates to rail anchors, more particularly to rail anchors of the two 1 piece type, and has for its object the provision of a new and improved rail anchor device of simple construction which device may be conveniently and quickly applied to or removed from a rail, which may be manufactured at a minimum cost. and which, when applied to the rail, will maintain a firm grip on opposite edges of the rail base, so as not to become loosened by the vibrations of the rail or other disturbing influences.

The invention consists in the new and improved constructions. arrangements and combinations of parts hereinafter described and claimed for carrying out the above stated objects and such other incidental objects as will appear from the following descri tion.

T e invention is illustrated in a preferred embodiment in the accompanying drawing, wherein- Fig. 1 is a fragmentary view in plan of a railway rail showing an anchor device constructed lIl accordance with my invention applied thereto in its operative position.

Fig. 2 is a sectional view taken on line 22 of Fig. 1, looking in the direction indicated by the arrow, and

Fig. 3 is an end view of the structure 40 shown in Fig. 2, this view being taken from the right hand side of Fig. 2.

Like characters of reference designate like parts in the several figures, of the drawing.

My improved rail anchor, in its preferred form consists of a shoe and a siring yoke member 11, which together em race the base of a rail 12 and grip the same with a combined spring pressure and shackle hold. The shoe member is preferably, though not necessarily, made of cast metal and is provided with a recess13 which defines the upper and lower jaws 14 and 15 which fit over one edge of the rail base and bear against the upper and lower surfaces thereof. The forward face 16 of the shoe 1921.' Serial No. 486,402.

member is flat and is adapted to bear against the adjacent face of the cross tie 17. In order to provide a relatively large bearing surface for the tie abutting face 16. without adding additional weight to the shoe. the shoe member is formed with a flanged portion 18. The rear face of the shoe member is formed with an angular projection 19, one flange 20 of which bears against the upper inclined surface of the rail base and the other flange 21 of which is adapted to engage with the vertical edge of said base and preferably to extend a slight distance below the lower edge of the rail base. Another projection or arm 22 is formed on the rear face of the shoe member at a point, preferably, below the projection 19, and functions as a support for one end of the spring yoke member 11. This projection may be of any suitable configuration in cross section, though it is preferably made angular and arranged, as shown in Fig. 2, so that the lower edge of the yoke member 11 will bear against a relatively small area of the arm. With this arrangement, the yoke member 11 may assume various diagonalpositions across the rail base without any appreciable resistance being presented by the frictional contact of the yoke with the arm portion22 of the shoe.

The spring yoke member is formed at one end with a jaw portion 23, having a lip 24 bent backwardly from the tie 17 which lip engages with the upper surface of the rail base. The other end is formed with an upstanding portion 25 which engages with the outer face of the flange 21 of the angular projection 19 of the shoe member. The body portion 11 of the spring yoke member is normally flat when free of the rail and is of a greater width than the distance between the projections 19-22 of the shoe so that it is necessary to twist the yoke before it can be positioned-(as shown in Fig. 3) between the said projections.

In applying the anchor, the shoe member is applied over one edge of the rail base with its tie abutting face 16 adjacent one of the cross ties of the road bed. The jaw portion 23 of the yoke is then hooked over the other edge of the rail base, A suitable wrench (not shown) is then applied to the upstandingportion of the yoke andthe body portion twisted backwardly from tie to a position substantially as shown dotted the lower edge thereof and a second projecjected to a torsional strain when'applied,

wi l assume a cramped position between the projections l9-22 of the shoe. The torsional strain of theyoke, in addition to maintaining a firm engagement between the shoeand yoke members will also effect a firm spring-pressure engagement of the jaw end 23 of the yoke with the upper and lower surfaces of the rail base. The jaw end 23 of the yoke may be driven toward the cross.

tie against which the shoe member abuts until the yoke'assumes a diagonal position across the rail base suitable for effecting a firm shackle hold on opposite edges of the rail base when the device is subjected to a creeping pressure of the rail.

I claim:

1. A rail anchor comprising a shoe member formed with a jaw to engage one edge of a rail base and with means defining the upper and lower edges of a recess, and a spring member formed with a jaw for engaging the other edgeiif' said rail base and adapted tobe positioned in saidg'ecess and be supported on said. means vdelinin the lower edge iwlsaid recess; the body 0 said spifing meme-er being of greater width than the distance between {said-assess defining means whereby it is nsceary to subject it to a torsionalstram in applyingit to its opcrative positionw g 4 2. A railanchorccomprising'a'shoe member adaptedto fit over one edge of a rail base. formed with an angular projection which engages with. the upper and vertical surraces of said rail base and provided with a second pro ection .whic'h'together with said first mentionedproject-ion and the rear face of said shoe define a recess, and a spring yoke formed at one end with rail engaging means and at the'nther with an upstanding portion adapted to engage with the outer surface of said shoe; the body. portion of the yoke intervening between'atssaid rail eugaging means andupstanding portion-being of greater width' than said recess and adapted to be twisted and positioned 'in said recess.

'3. A rail anchor comprising a slice member adapted to fit over one edge of a rail base, formed with an angular projection "having a lateral flange which engages with the upper surface of the rail'ba'se and a vertica flange engaging the vertical surface of the .rail base and extending below being of greater width than said recess and adapted to be twisted and positioned insaid recess.

4. A rail anchor comprising a shoe member adapted to fit over one edge of a rail 'base formed on its rear face with an angular projection which fits over the upper corner of the rail base and extends below the lower edge thereof, a second projection arranged below said first projection, which defines the loweredge of a recess, and a normally flat spring yoke formed at one end With a jaw having an angularly disposed lip for engaging the upper surface of the rail base and at the other end with an upstanding portion for engaging the outer surface of said angular projection, the portion of the yoke intervening between its rail engaging jaw and said upstanding portion being adapted to be given a torsional twist and positioned between said projectionsand in binding engagement therewith.

5. A rail anchor comprising .a spring metal yoke provided with a body portion formed at one end'with a jaw adapted to hook over one edge of a rail base and at the other end with an upstanding portion, and a shoe member adapted to fit over the opposite edge of the rail and formed with an angular projection intervening between the rail base and said upstanding portion of said yoke and provided with a projection for supporting said yoke in its applied position; the body portion of said yoke being adapted to be subjected to a torsional strain and positioned between the said projections and in binding engagement therewith.

6. A rail anchor comprising a shoe member-formed with a jaw to engage one edge of a rail base and with upper and lower arms extending longitudinally of the rail to provide a recess, and a spring member formed with a jaw for engaging the op- .posite edge of said rail base and with a body portion extending transversely of said rail base adapted to be positioned in said duo recess, whereby canting of said bod is required to permit its entrance i to sai recess.
