SAFETY ANCHORING-BLOCK.

Specification of Letters Patent.

Patented Mar.- '1, 1921.

Application filed August 19, 1920. Serial No. 404,612.

To all whom it may co'ncem:

Be it known that 1, JOHN E. WHILT, a citizen of the United States, residin at Eureka, in the county of Lincoln and tate of Montana, have invented certain new and useful Improvements in Safety Anchoring- Blocks, of which the following is a specification.

The object of my invention is to provide an anchor block for securely anchoring railway cars on an inclined track while they are being loaded and is designed especially for use with logging railroads, but it can, of course, be employed wherever it is necessary or desirable to securely block or anchor a railway car securely in place. It is well known that the ordinary hand or air brakes cannot be relied upon to hold a car for any length of time, and accidents have frequently occurred through the failure of the brakes. The element of danger due to this cause is entirely removed by the use of my device.

The invention consists of the features of construction, combination and arrangement of parts hereinafter fully described and claimed, reference being had to the accompanying drawing, in which Figure 1 is a side elevatlon showm my device in position, and Fig. 2 is an en elevation of the same.

Referring to the drawing, 1 is a railroad car wheel resting upon the rail 2, which in turn is secured to the usual tie 3. My improved block is represented as a whole by the numeral 4: and consists of a block of wood or other material 5 having one side curved to fit the periphery of the car wheel, the base being straight and resting on the rail, the other two sides can have any suitable angular relation with each other and with the other two sides, but a block having two right angles, one obtuse and one acute angle has a substantial and pleasing appearance, and such shape has, therefore, been shown. The curved side of the block is preferably covered with an iron or steel member 6, bent to the proper shape and secured to the block by bolts or screws. The memher 6 is provided with a wedge shaped portion 7 extending under the wheel and of sufficient length to permit the wheel to rest thereon. This portion 7 is furthermore provided with downwardly projecting flanges 8 on each side of the rail, the purpose of which is to prevent lateral movement of the block. To prevent the block from sliding along the rail I provide downwardly projecting members on each side. These members are preferably made of an angle iron 9 and a flat bar 10, secured to the block by bolts or rivets 11 and securely riveted to each other as shown at 12, thus forming a rigid triangle in which the angle iron serves as the compression member and the bar as a tension member. The triangle formed by the bars 9 and 10 and the block 5 projects below the base of the block to such a distance that when the block is in position on the rail the apex extends below the base of the rail and into the ground on the upper side of the tie, or the apex can be placed directlyupon the tie in which case the weight of the car will force the members into the wood; in either case the block is positively prevented from sliding along the rail. In order to remove the block in case it should stick to the tie, I provide it with a cut away portion 13 so that a bar can be readily inserted and the block pried loose.

It will be noticed that after the car wheel has been rolled onto the block the latter will be positively held in place and cannot be removed until the car is moved uphill sufficiently to free the block from the weight of the car; this insures that the block cannot be removed until the engine is in place and sufiicient force has been exerted to move the car and its load against the action of gravity.

The block can readily be made in any blacksmith shop without the aid of any special machinery, and will be comparatively light and easily handled. Although I have shown the block as made of wood and suitably reinforced with iron, it can, if desired, be made entirely of iron or steel.

Having now described my device, what I claim is my invention or discovery is:

1. A safety anchoring block, for the purpose specified, comprislng a block having one side straight and adapted to rest on the upper face of a railroad rail, the side-adjacent thereto curved, whereby it will conform to the outer surface of a car wheel; means on said block comprising downwardly extending flanges for engaging each side of a rail to prevent lateral displacement and downwardly projecting anchoring means on each side of the block for engaging with i the road construction and positivel preventing longitudinal movement 0 said block.

2. In combination with a car wheel a railroad rail and-a cross tie of means for positively holding the said car wheel in osition on an incline comprising a bloc of substantially trapezoidal shape, the base of which rests on the rail and one side of which engages with the car wheel, said block oeing provided with means to prevent lateral movement with respect to the rail and means for engaging with the road construction for preventing longitudinal movement thereof.

3. A safety anchoring block for the purpose specified, comprising a substantially trapezoidal shaped block means near one end thereof extending downwardly on each sidethereof for preventing lateral displacement when said block is placed on a railroad "rail, anchoring means comprising downwardly extending members rigidly secured to said block, for engaging with a cross tie and preventing the block from sliding longitudinally when placed on a rail.

4. A safety anchoring ance with claim No. 3 in which one side is curved in the are of a circle and has a tangential portion extendin beyond the point where a radius perpen icular to the base cuts said are.

5. A safety anchoring block in accordance with claim No. 3 in which the anchoring means comprise an angle iron compression member and a bar iron tension member, whifh together with the block form a trian e.
