CLARENCE I). POBTERFItELD, OF NEW YORK, N. Y.

RAIL-ANCHOR.

Application filed June 24, 1914.

To all whom it may concern: v w

Be it known that I, Cnamzxon D. PORTER- FIELD, a citizen of the United States, residing in New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Rail-Anchors, of which the following is a specification.

My invention pertains to anchors for pre venting railroad rails from creeping. 1

It comprises but two parts, an anchor and a wedge, both blanked from steel plates and stamped and bent into their final forms, and therefore economical and adapted to i be turned out in great quantities by automatic The improvement in my device consists in malnng it from a sheet metal stamping,

and is therefore resilient, and so arranging the structure that any creeping of the rail which it grips, deforms or distorts the device. This distort-ion causes an 1116113386 111 the grip of the anchor upon the rail, through usual.

s 31, terminating in a Wider butt 32.

the foreshortening of the sides of the triangularlykdisposed base grips, and which foreshortening, together with the above noted resiliency of the device, forms the important part of my invention.

Figures 1, 2 and 3 are perspectives. Fig.

1 shows the rail baseand web in section and the mode of putting on the anchor, Fig. 2 shows it in place. Fig. '3 shows one side of the rail and the anchor head. Fig. 4- is a plan View.

The rail is of common section, with base flanges 2, 2, and is spiked to the tie, 1, as The anchor 3 is blanked from steel plate and bent into the shape of a 7. It has a head, 30. broadest at its free edge for a large abutting face 35, and a narrow tang, Flange notches 33, to fit closely on the margins of the base are located in the free end of the head and in the inner side of the butt and a wedge notch. 34, to fit'the base margin and wedge, is blanked at the junction of the head and tang. The distance from the root of the Wedge-notch 34- to the fluke, 37, of the opposite flange-notch, slighl y exceeds the Width of the rail base, so that the anchor can be put on the rail.

Specification of Letters Patent.

Patented Apr. 20, 1915.

Serial No. 846,958.

The notched anchor plate is bent into shape, the end of the head bent-inward to are'bent outward and the butt flakes 37 bent inward to facilitate putting the anchor on the rail-base. The wedge 4 is tapered, offset to fit on and ride the raiisfiange and slotted to form a narrow fork -10.

To apply the anchor, the tang 31 is passed nearly at'right angles under the raii ham with the notches upward and the wedgenotch 34 riding the rail-base. The tang 31 is then raised to the base and the butt 32 swung toward the abutting face 35 to cause the butt-fiukes 37 to ride the base and the free head fluke 36 to bearing end 35 of the head is raised, and the Wedge 4 is inserted from within the head, into the wedge notch 34 and riding the rail base, which draws the anchor into sliding engagement with the rail base. The anchor is then driven home, with its face 35 against the tie l, the wedge 'l is forced home with a crow-bar which is wedged between the end of said wedge and the inner face of the butt and its fork d0 of the wedge is bent down, to lock the anchor. This mode of application puts the anchor under triangular stress, as indicated by the dotted triangles and the dotted and. full lines of'the head, in Fig. i.

It is obvious that the head 50 resists creeping stresses elastically and therefore is not likely to gouge the tie as rigidanchors do, and is even more reliable in its action; and also that use tightens the grip of the anchor to the base because of the obliquity .cf the tang 31 to the rail and the-projection of the head 30 therefrom.

It'is obvious from the foregoing that placed against the tie, and that the same clear it; whereupon the tempering the steel,

form a tie face 35; and the head fiukes 36 engage a'railroad rail and tie comprising resilient oppositely arranged rail-base en-' gaging members integrally connected, one of said base -,engaging members against the tie, and tension increasing means between said resilient members.
