RAIL ANCHOR.

Specification of Letters Patent.

Patented Feed, 1922.,

Application filed August 31, 1921." Serial No. 497,175.

T 0 all whom it may concern:

Be it known that I, HARVEY P. MCFAR- LAND, a citizen of the United States, residingat Burlington, in the county of Des Moines and State of Iowa, have invented certain new and useful Improvements in Rail Anchors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and 'use the same;

This invention relates to a rail anchor ofthe type designed to prevent forward movement or creeping of the rail and comprising a device arranged to be attached to the rail and to bear against one ofthe cross ties to which the rail is secured. V

. It is an object of this invention to. providesuch a device of few and simple parts whichgcan be quickly attached to and removed from the rail. It is a further'object of this invention to proconstruct such a device having a member underlying the rail, an anchor block mounted thereon and co-operating therewith to clamp the rail, together with a detachable clamping means adapted to bear against the anchor block and move the same into and hold the same in clamped position.

These-and other objects and advantages of the invention will be fully' set forth in the following description made in connection with theaccornpanying drawings in which like reference characters refer to the same parts throughout the different views and in which- Fig. 1 is a side elevation of the device, a portion thereof being shown in section and showing the same applied to a rail;

Fig. 2 is a top shown in Fig. 1; and

Fig. 3 is a sectional view taken on the line 3-3 of Fig. 1, looking in the direction of the arrows. 7

Referring to the drawings, a standard type of rail is shown as a, which is secured in the? usual manner to a cross tie connected at b. The rail anchor proper comprises a member 1 known as a hook bar which is of general rectangular cross section and provided at one end with an upwardly extending hook portion 1". The bar 1 is adapted to underlie the rail and extend transversely of the same and the hook 1 is adapted to plan view of the device contact with the side and overlie one edge of therail flange. The bar '1 hasadjacent its other end a slot 1 extending therein from its top surface and projecting downwardly toward said end. Mounted to slide upon the bar 1 and having an opening through which said bar extends is an anchor block 2 formed at its top portion as a hook member adapted to contact the edge of and extend over the rail flange'opposite the'side contacted by the portion '1 of the hook bar. The member 2 extends down the sides of and under the bar 1 and one side thereof is lengthened'by an extension 2*, as shown in Figs. 1 and 2, and this side of the anchor block 2.is adapted'to contact the side surface of the crosstie b. The device also comprises a pawl'member 3 formedwith a bifurcated eccentric hub having a pin/.1; extending through the center thereof and between said bifurcations. The pawlis arranged to be disposed withthe bifurcatio'ns thereof straddling the bar l'with'the pivot pin 4 seated in the bottom of the slot 1'. When the pawl is rotated about its pivot the eccentric hub portion thereof will bear against the outer side of the anchor block 2 and move the same toward the hook end of the bar 1, thus clamping the rail firmly between said hook portion and anchor block.

The pawl 3' is provided with a handle portion 3 by which it is swung and this portionis also arranged to act "as a stop'a'nd contact with its concave surface, the top of the anchor, block 2, in which position the longest radius of the eccentric hub is in contact with the anchor block. The anchor block 2 is provided with cutaway portions 2 at each side to lessen the weight thereof.

The operation of the device will be apparent from the above description but the same may be briefly summarized as follows:

The bar 1 is placed under the rail with the hook portion 1 extending over one side of the flange thereof. The anchor block 2 is then moved against the other side of the rail extending over the flange thereof. The pawl 3is then placed in the slot 1 in the position shown in dotted lines in Fig. 1 and then swung to the position shown in full. 7

lines, which motion will move the anchor the anchor block in contact with the side surface of the tie b. The rail is thus firmly and rigidly clamped and any creeping thereof longitudinally, relatively to the cross 'tie, is prevented.

From the above description it is seen that applicant has provided a rail anchor of three simple and quickly removable parts which anchor can be quickly applied to the rail and as quickly removed therefrom. The parts can be made rigid and with little ex-. pense. When once made, they have no tendency to become disarranged or'broken.

It will, of course, be understood that various changes may be made in the form, details and proportions of the parts without departing from the scope of applicants invention, which generally stated, consists of the matter shown and described and set forth in the appended claims.

What is claimed is:

, 1. ,A rail anchor comprising a member underlying a rail and arranged to extend over the flange at one side thereof, means movable relatively thereto for clamping the rail adapted to contact with the cross tie, and cam means detachably engaging said member for clamping said means against the rail.

2. The structure set forth in claim 1, the first mentioned means comprising a member embracing and movable on said first mentioned member.

3. A rail anchor having in combination a hook member having a hook at one end adapted to receive one edge of the rail flange, an anchor block slidable thereon and adapted to extend over the opposite edge of the rail flange and to contact with its side surface the side of a cross tie, an eccentric means carried by said bar engaging with 7 said block to move and hold the same in jclamping relation to the rail.

4, A rail anchor having in combination a substantially rectangular bar adapted to extend transversely under the rail, an anchor block mounted for sliding movement on said bar arranged to extend under and over the opposite edge of the rail flange and to cooperate with said bar in clamping the same and an eccentric adapted to bear against said block and move the same in clamping relation to said rail.

5. The structure set forth in claim 4, said pawl having a handle extension thereon and adapted to contact with the top of said block to limit the movement of said pawl. I r

6. A rail anchor comprising three members, a barhaving a hook at one end and a slot formed therein at the other, an anchor block slidable on said bar and co-operating with said hookto clamp the rail, and a removable clamping member adapted to be received in said slot in said bar.

7. The structure set forth in claim 6, said clamping member comprising a bifurcated eccentric hub having a transverse pivot pin i secured therein and extendingbetween said bifurcations, said pin adapted to seat in said slot in the bar so that when rotated about said pin the eccentric hub will move said anchor block to hold the same in clamping position. v

8. A rail anchor having in combination a hook bar transversely underlying the mil with the hook extending over one edge of the flange thereof, an anchor block-slidable thereon having a hook extending over the opposite flange edge of the rail'and a removable eccentric clamping pawl seated and rotated in a slot formed in the other end of the bar. 7 I

In testimony whereof I afiix my signature in presence of two witnesses.
