Rain-ANCHOR.

Application filed July 11, 1908. Serial No. 443,149.

T 0 all tvhom it may concern:

Be it known that I, CLARENCE D. Pon'rnn- FIELD, a citizen of the United States, residing at New Brighton, Staten Island, borough of Richmond, city, county, and State of New York, have invented certain new and useful Improvements in Rail-Anchors, of which the following is a specification.

The invention relates to such improvements; and it consists of the novel construction and combination of parts hereinafter described and subsequently claimed.

Heretofore there have been many inventions seeking the prevention of movement ofthe rails by means of devices fastened to the rails by bolts, wedges, etc., but these have been found unsatisfactory as the vibrationand thrust of the rails, and expansion and contraction caused by variations of temperature, operate 'to loosen the device on the rails which results in the non-holding of "the rails to the ties.

My invention does not depend on bolts or other means independent of the movement of the rails, to effect a practically immovable contact between the device and the rail the yoke, bears against the tie or rail support anchoring the rail to the tie which in turn anchors the rail to theroadbed.

Reference may be had to the'accom'panying drawings and the letters of reference marked thereon which form .a part of the specification. I

Similar letters refer to similar parts in the several figures therein.

'In the-accompanying drawings Figure 1 is a vertical end view showing my invention embracing arail base shown in cross section. ,Fig. 2 is a side elevation showing my invention embracing a rail base and resting against the tie or sleeper. Fig. 3 is a plan view of my invention embracing a rail base. Fig. 4 is a plan view of another form of my invention embracing the rail at an angle of about 30. Fig. 5 is an isometric view of the wedge part of my invention showing a form of wedge with an elevated shoulder and Specification of Letters Patent. Pai nted Aug, 30,=1910.

a foreign substance embedded in theupper I surface of the wedge where it comes in contact with the bottom of the rail. Fig. 6 is a vertical end view of another form of my invention in which only one side of the wedge tapers. Fig. 7 shows anotherform of my invention in which a groove inthe under side of the wedge receives a tongue upon the upper side of the bottom of the yoke.

Fig. 8 is a side elevation of a part of the rail with my invention as shown in Fig. 7, embracing the rail base. Fig. 9 is a plan view of my invention as shown in Fig. 6. Fig. 10 is a plan view of my invention as shown in Fig. 7. Fig. 11 is another form of my invention in which a tongue upon the wedge engages with a groove in the yoke... Fig. 12 is a side elevation of a part of the rail with my invention as shown in Fig. 11 embracing'the rail base. Fig. 13 is a plan view of my invention as shown in Fig. 11. Fig. 14 is another form of my invention as shown in Figs.'11, 12 and 13 with the yoke at an angle of about 30, to the edge of the rail flange.

My device is superior to other forms using a wedge in that it is simpler of construction, has fewer parts, is easier to apply to the rails and can be made at a much lower cost.

Referring now to the accompanying drawings, R is the rail, W is the wedge, T is the tie, Y is the yoke or clamp, T is the downwardly extending flange or lug of the wedge which rests against the tie or sleeper.

It will be noticed that I make the yoke or clamp Y in different forms, the upwardly extending ends 6 e, and the clips 0 c varying according to the shape of the wedge used and the angle of the yoke when finally ad-' This form is ap-""'- plied to the underside of the rail R from which it is suspended by the clips 0 c. The wedge W is then placed with its shoulder T against the tie or sleeper and its 0pposite end between the yoke Y and the rall R and the yoke Y is driven toward the tie 0r between the wedge and the yoke.

apply the yoke to the rail, said inside lateral surface being sloped or inclined as shown best in Fig. 1. The inside vertical surface of the yoke is also sloped or inclined at an acute angle to the edge of the rail flange on one end of the yoke, 'as shown in Fig. 3. This slo ed inside vertical surface engages the s oped side of the wedge and wedges the inside surface of the yoke and the vertical edgeof the rail flange; the bottom incline of the wedge engages the bottom of the rail and the inside lateral surface of the yoke, thereby causing practically immovable contact at points 1, 2, 3, 4, 5, 6 and 7. Thewedge may be reduced in both lateral and vertical thickness at the free end for the purpose of securing a wedglng surface on the upper or under sideand also on the vertical side. As shown in Fig. 5, I have also found it advantageous in some cases to have a shallow depression in the upper surface of the wedge in which can be inserted a different material, such as I wood, carborundum, etc., that the base of the rail may be more firmly gripped.

In Figs. 6 and 9 I show a form of my device in which the yoke Y is made with the ends ee having inside bearing surfaces 11 and 13 which contact with the vertical edge of the rail flange, and clips 0 c with inclined bearing surfaces which contact the upper sloping surfaces of the rail flange.

' The clamp is applied from the underside of slightly indented or ribbed or serrated for the purpose of facilitating the ri ing.

In Fig. 7 I show another ioi hi of the yoke Y in which the tongue or lug p projecting upwardly from the upper side of the inside bottom surface of the yoke Y en gages in a longitudinal groove in the undein side oi the bottom surface of the wedge, servin to hold'the latter in place during I and a er adjustment of the yoke.

5 longitudinal the bottom 0 In Fig. 11 my invention is shown with a tongue or lug 0, which projects downwardly from the wedge W and engages with a groove in the u per surface of the clamp Y -or the purpose of holding the'wedge in position during and after ad ustingnt. When the wedge and scene yoke are in position there is practically immovable contact at the points 16, 17,18

and 19.

In Figs. 1, 7 ,and 11 the opening between the edges of the clips 0 c and between the under surface of the clips 0 c and the upper side of the bottom of the yoke Y and between the inside veitical edges of the ends 6 e, is suflicient to permit the application of the yoke to the rail byhooking on first one end of the clamp at an angle that will permit one edge of the rail flange to enter the yoke to a point where the other edge of the rail flange can also'enter the yoke.

The form of my device shown in Figs. 4, 9 and 14. is applied to the underside of the rail with the rail base at right angles to the lateral length of the yoke. The yoke is then slued around until the oblique vertical edges of the ends 6 e are parallel with the edges of the rail flange after which the wedge is introducedbetween the yoke and the base of the rail and practically immovable contact is secured at 20, 21 and 22.

Having thus described my invention, what I; claim as new and desire to secure by Letters Patent is as follows:

1. A. device of the character described, comprising a yoke adapted to be adjusted to the rail base at right angles to the axis of said base and then swung so that the base of the yoke is at an acute angle to the'axis of said base, and a wedge, bearing at one-,end against the rail support, and engaging with the opposite end between the under side of the rail base and the upper surface faceof the base of the yoke.

2. A device of the character described,

which is at an angle to the axis of the yoke,

and a wedge adapted to engage between the yoke and the under side oi the rail base with one end and bear against the rail support with the opposite end.

A device of the character described, comprising a yoke with upwardly extending ends, the inside vertical surfaces of which are at an angle to the axis of the yoke, and a wedge adapted to engage between the upper surface face of the base of the yoke and the under side of the rail base with one end,

and bear against the railsupport with they opposite end. i

5. A device of the character described,
