To all whom it may concern:

Be it known that we, VAN and LAURENCE J .BERKELEY, citizens of the United States, residing, respectively, at Chicago, inthe county of Cook and State of Illinois, and Evanston, lllinois, have invented. certain new and useful Improvements in Rail Anchors, of which the following is a specification. 1

Our invention relates to rail anchors and particularly to the general type of anchors in which arigid member and a spring bar cooperate to embrace the base of the rail and are maintained in their operative position on the rail by spring pressure produced by distorting the spring bar during its ap plication.

One of the objects of the invention 18 to provide animproved anchor of the above general character 'in which the spring bar is so positioned between the rail base and a part of the rigid member as to efi'ectafirm positive grip on the rail when the. rail is subjected to a force tending to move it -longitudinally. I it Another object is to provide an anchor of the above general type in which the gripping action of the device is soeffected as to permit a relatively light spring to be used and in which the spring is so formed as tor-increase its flexibility and thereby facilitate its application to the rail. andpermit a greater range of distortion than other types of springbars now in general use without sacrificing the resiliency required to maintain the anchor as a whole in its proper operative position.

Then invention has foi afurther object such other novel arrai'igemeuts constructions and combinations of parts hereinafter described andflclaimed for carrying out the above stated objects and such other objects as will appear in the following description.

The invention is illustrated in certain pre ferred embodiments in the accompanying drawings, wherein- Fig. l is a'front view in elevation of a twopiece rail anchor device constructed in accordance with this invention.

Fig. 2 is a side view in elevation of the structure shown in Fig. 1.

Figs. 3 and 1 are side and top views respectively of the spring bar member used in connection with the form of anchor shown in Figs. 1 and 2.

PATRICK H, .DON O modified form of anchor, and

Fig. 7 is a side View of the modification illustrated in Fig. 6. Like characters of reference indicate like parts in the several figures of the drawings.

Referring firstto Figs. 1 to 4 inclusive of the drawings: 10 designates a rigid member or shoe adapted to engage one edge of the rail base and 11 a spring bar formed to maintain the rigid member in operative position and adapted to grip opposite edges of therail base 12. The rigid member is made, preferably of cast metal and is provided with upper and

lower jaws

13 and 14, respectively, which are joined together by a vertical web 15 and fit over one edge of the rail base. A. depending flange 16 is formed at one. end of the jaw portion 10 to provide a suitable abutment for bearing against one of the vertical'faces of a cross tie 17. A depending flange 18 is formed at the other end of the jaw portion and'is provided with a projection or arm 19 which extends. longitudinally of the rail below the base 12, which arm is formed with a notch 20 to provide a suitable seat for the spring bar 11. The de

pending flanges

16 and 18 are reenforced by a connecting web 21. l i a l The spring bar 11 is formed at one end with a jaw portion 22 having an angularly disposed lip 23 bent in adirection away from the cross tie and adapted to bear upon the upper surface of the rail base on the side. of the rail opposite to that engaged by the rigid member 10. The body ofthe spring tapers in a direction towards the rigid member as shown by the reference numeral 2 1, to increase its flexibility, and terminates in an enlarged dovetail portion 25, which is disposed in an angular position between the lower edge of the rail base and the projection 19 of the rigid member 10 so as to function as a toggle whenthe rail is subjected to creeping pressure. The edges ZGa-nd 27 of'the enlarged portion 25 diverge from each other toward the end 7 .of the bar so that the edge engaging the the rail base. The lower edge of said dovetailed portion projects below the seat portion of the notch 20 and thereby prevents the spring from shifting in the direction or its length transverselyot the rail and also prevents lateral movement oi the rigid memher with relation to the rail. The spring member is normally flat and is oi greater width than the distance between the projection 19 and-the under surface of the rail base at the point engaging these members, whereby it isnecessaryto cant the spring body to permitthedovetail portion to be positioned between the projection 19 and the rail base. The torsioning-of thespring increases-thegr'ip ot' the jaw portion 22 on the rail and exerts sufiicientresilient pressure against the rigid member to resist any tendency that the vibration or the rail or the movementof the device through the ballast of the roadbedmay have to loosen theinitial lioldo'fi the anchor on the rail.

In operation, the rigid 'member is fitted over one edge of then-ail in a position to bear againsta cross tie. of the spring the other edge of the rail and the body oi the spring twisted suiliciently to permit the dovetail portion 25 oi the spring tobe positioned between the rail base and the projecti'on 19 oil the rigid member or shoe 10.

The aw portion The body portion of the spring intervening between its dovetail and jaw portions being reduced in cross sectional area increases the flexibility of the spring and also due to its small area of contact with the under suriaceot' the rail, prevents any rough spots that may be on' the under surface of the rail 't'roin interfering with the proper'gripping engagement between the dovetail portions and the rail base. The spring bar normally stands at right angles to the length of the rail but may be readily shifted to a position diagonally across the-rail if such position is-required to accommodate rails having base flanges of less'width than that shown in the drawings.

In Fig. 5 a modified construction is illustrated in which the upper edge 26 of the enlargement 25 01 the spring 11 is formed parallel to the lower surface of the rail base so as to grip a larger area of the under surface of the rail base than the form shown in'Figs. 1 to 4- inclusive. In other respects this modification may beand preferably is the same as that shown in Figs. 1 to i in elusive-or the drawings.

In Figs. 6 and 7 another modified con,

struction is illustrated in which the rigidmember or shoe-consists of two flange mem bers each of which is formed with a recess 30* whichfit s over and engages with the upper and lower surfaces of the rail base. The flanges :28 and 29 are secured together near their upper ends by means of an anbar may then.- be hooked over gular jaw portion 31 which bears against the uiper surface of the rail base. The vertical portion 32 of this jaw portion however stops short ot the lower edgeoii the rail base so that it will not interfere withthe proper grip of the spring on the lower edge of the rail. The lower portions of the flanges 2S and 29 are secured together by means of an integral arm 33 which in this modification functions in the same manner as the arm or stud 19 in the Figs. 1 and 2.

The spring barmember as shown in' this modification may be the same as either of the forms snown in Figs: 1 -0r 5. However, for'the purpose of convenience the spring bar shown in Figs. 1 toat inclusive is used in connection withthis modification as a specific illustration and has been given corresponding-referencenumerals with the ex ponent b.

In operation the jaw end 22 of the spring bar ll is first hooked over one edge oi the rail basewith the body of the bar extending; transversely out the rail. Suitable applying tongs (not shown) may then be extended through the opening 3450f the rigid men:- ber a distance snilicient'to grasp thedovei 'il portion 25 of the spring bar may then be torsioned' sutliciently to permit the dovetail portion 25 to pass through the opening 34: of the rigid member, the spring may then'be released, whereupon the inclined upper an'd'lower edges 26 27" will be forced into engagement with the lower corner oi the rail base and with the arm 3; and held in such engagement by means of the torsion to which the spring has been sub jected. Wh'en the rail tends to move in the direction toward thetie the creeping movement tends'to move the portion 25 oi the spring member toward a vertical position whereby the portion'25 becomes tightly cramped between the rail base and the arm 33.

While the invention herein has been shown in certain specific embodiments in which the flexibility of the sp'ringis increased by re (lucing the widthof'thc spring, it will be obvious-that the flexibility of the spring may be increased in other ways than illustrated therein and that the various other featuresv of the invention might be accomplished by modified structure. It should theretorebe understood that this invention contemplates all such modifications in structure as come within the scope of the appended claims.
