RAIL ANCHOR Filed Aug. 50, 1927 INVENTOR 7W Wtc 8M Adv; ATTORNEYS Patented Dec. 10, 1929 UNITED STATES PATET OFFICE CHRISTIAN KONOLD, OF VERONA, PENNSYLVANIA, ASSIGNOR 'IO GREEPGHECK COM- PANY, INC., OF NEW YORK, N. Y., A CORPORATION 0F NEW YORK BAIL ANCHOR Application filed August 30, 1927. Serial Ii'o. 216,367.

This invention relates to rail anchors and more particularly to one piece or unit anchors.

An object of this invention is to provide a one piece or unit rail anchor capable of use rail base.

Another object of this invention is to provide a one piece or unit rail anchor the rail base grip of which may be adjusted These and other objects which will be apparent to those skilled in this art are attained by means of the device hereinafter described and claimed and illustrated in the accompanying drawings.

In the drawings, Figure 1 is a side elevational view of a rail anchor embodying the invention shown applied to a rail.

Fig. 2 is a view similar to Fig. 1 show ng the anchor of Fig. 1 applied to a rail having a narrower base and,

Fig. 3 is a view similar to Figs. 1 and 2 but showing a modification of this invention.

The anchor of this invention is shown applied to a rail having a web 11 and a base 12 with edges 13 and 1 1 for such base.

The anchor is made from a single piece of metal preferably steel of the proper carbon content and preferably from bar stock. One end of the anchor 15 is formed in a shape of a hook 117 the inner faces of which form a aw 18 for cooperating with the edge 14 of the rail 11. The jaw 18 is of suiiicient depth to engage an appreciable portion of the rail edge ll to prevent damage to the edge 14. lhe remaining portion 19 of the anchor 15 is bent downwardly and away from the base of the rail and terminates in an upwardly extending portion 21.

Upon moving the portion 21 111 an upward direiiti'on the top face of the curved portion 22 will come in contact with the lower face 23 of the rail base 12 and act as a fulcrum.

The means 16 which is disposed on the right face of the upwardly extending portion 21 comprises a plurality of projections 24 which are adapted to cooperate with the edge 13 of the rail 11. The spaces between the projections 24 provide jaws or seats for receiving the edge 13 of the rail 11 and cause the anchor 15 to tightly grip the base 12. The portion 21 is provided with a cam surface 25 for preliminarily engaging the edge 13 and guiding the anchor upwardly until the top portion of the edge 13 passes under the desired extension 2 1, the resiliency of the anchor 15 serving to firmly hold the same in proper contact with base 12, see Figs. 1 and 2.

In applying the anchor to the rail the hook portion 17 is first placed over the face 14 of the rail 11 and a suitable tool is used for exerting upward. pressure on the portion 19 which will tend to slightly straighten the anchor 15 causing the portion 21 to move upwardly until the top portion of the edge 13 of the rail 11 comes into engagement with the lower portion of the desired projection 24.

The portion 19 of the anchor 15 extends downwardly a considerable distance from the bottom face 23 of the rail 12 thereby providing ample surface for cooperation with the tie 26 as is shown by Fig. 1.

Referring particularly to Fig. 3 in which I illustrate a modification of the means for permitting adjustment of the anchor to rails having bases of different widths. I provide a plurality of projections 26, 27, 28, etc., or an irregular surface which would constitute a plurality of projections for cooperating with the edge 13 of the rail 11. The distance between the uppermost projection 26 and the inner face of the groove or slot 18 on the 0pposing side of the anchor 15 is greater than the distance between the projection 27 and the inner face of the slot or groove 18,and so on. The distance between the lowermost projection28 and the inner face of the slot 18 is shorter thanany of the distances between either of the projections 26 or 27 and the inner face of the slot or groove 18.

In addition to the distances just mentioned becoming shorter between the projections and the inner face of the jaw 18 the gripping power of the anchor 15 is increased as the portion 21 is moved upward.

It can be seen from the above description that Ihave provided a one piece or unitary rail anchor which can be adjusted torails having bases of different widths so as to have suli'stantially the same holding power on these rai s.

It will be observed that it is essential incarrying out my invention that, whether there are two humps 24, 24, as shownin Figs. land 2, or three humps, as shown in Fig. 3, the inner; surface of the upstanding member 21, at a point below the cam face 25, shall be substantially serpentine in shape, so that the upper rounded surfaces-of the lower hump or humps shall serve as camsurfaces, in the manner of the c'amrsurface 25, so as to assist: in springing the upstanding member outwardly far enough to engage the upper'corner of the rail edge under the lower hump.

While I have illustrated and described but 5 one embodiment of this invention it will be apparent to. those skilled in the art that certain changes, modifications, substitutions, additions and omissions may be made in the de vice without departing from the spirit and scope of the appended claims.

What I claim as new and desire to secure by Letters Patentis:

' 1. Arailanchor comprising a resilient yoke with one face adapted to lie against the tie and having a bump which when the anchor is in operative positioncontacts with the bot-- tom of the rail-base to form a-fulcrum, a jaw at one end for engaging. one edge of the rail-base, and a springy upstanding-end-portion at the other end whose inner face is adapted to engage the other edge of the rail when in operative position, said innerface having a substantially sepentine formation to provide a plurality of roundedhumps any one of which is adapted to engage over the uppercorner of the rail-edge to lock the anchor to the rail, for the purpose set forth.

2'. A one piece rail anchor having a-hook endadapted to receive oneside of a rail flange and an oppositely located upstanding end.

adapted'to engage the other side of the rail flange, the upstanding end having a cam face for preliminary engagement withthe rail flange for spreading theup'standing end away from the hook end, the'last named end having a plurality of rail seating recesses, the ,distance between each of the recesses and the opposite end of the anchor being different to afford means for positively locking th'e anchortodifl'erent width of rails.

3. A one piece rai'llanchorhavingja hook endadapted to receive one side of. a railflange and an oppositely located upstanding end adapted to engage the other side of the CHRISTIAN KONOLD.
