FASTENING FOR CAR SAFETY-CHAINS.

SPECIFICATION forming part of Letters Patent N o. 720,224, dated February 10, 1903.

Application filed August l1, 1902.

:To all whom t may concern:

Be it known that I, ANDREW CHEISTIANsoN, a resident of Allegheny, in the county of Allegheny and State of Pennsylvania, have in- Vented a new and useful Improvement in Fastenings for Car Safety-Chains; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to railway-cars, and

:lo more especially to means for securing safetychain eyebolts to a metallic car.

The invention consists in the details hereinafter described and claimed.

In the accompanying drawings, Figure 1 is r 5 a plan View, partly in section, of the end lof a car, showing my invention applied thereto. Fig. 2 is a longitudinal section through the end of the car, showing the eyebolt and fastening means in side view. Fig. 3is a section zo on the line 3 3, Fig. 2; and Figt is a side view of the connecting-angle.

The car-body may be of any desired or preferred construction, that shown in the drawings comprising a metallic end sill 1, having z5 a vertical web and an inturned flange 2 at its bottom.

3 shows a floor plate having upturned lianges at its edge which floor-plates are riveted to the end and side plates of the car.

The specific form' of end sill'shown has its web continued upwardly to form the end plate of the car; but this is not essential.

The safety-chain eyebolt is shown at' 4, having the eye at its outer end and having a 3 5 shank 5 extending through a hole in the end sill, and also havingy a shoulderor collar 6, which bears against said end sill.

7 is a section of angle-bar having its horizontal ange riveted to the door-plate 3 and 4o having its forward end abutting against the end sill or end plate of the car. To the vertical fiange of this angle-bar is secured a strap 8, which encircles the shank of the eyebolt and has two iianges which t over the vertical iange of the angle 7. .Rivets, bolts, or othery suitable devices pass through the iianges of the strap and through the vertical flange of the angle 7 and unite these members. The strap 8 is attached to the angle 7 in such 5o position that its forward end is flush with the forward end of the angle, so that the ends of both the strap and the angle bear securely Serial No. 119,230. (No model.)

against the end sill or end plate. This partially relieves the rivets which unite the strap to the angle and also the rivets which unite the angle to the Hoor of shearing stresses. The shank of the eyebolt 4 passes through the strap and is provided at its rear end with threadsfor receiving a nut 9, which holds the eyebolt from pullingout. This nut, together 6o with the collar G, bearing against the front face of the end sill or plate, firmly binds the strap 8 to the end sill or plate.v The vertical fiangeof the angle 7 is cut away at its rear portion, as shown at 10, in order to provide clearance for turning the nut 9.

The angle 7 and strap 8 are simple of construction and provide a secure holding means for the safety-chain eyebolt.V They are so connected to the car as to relieve the con- 7o necting rivets or bolts of Amost of the shearing stress.

It is obvious that in place of the angle-bar 7 any other flanged shape which will provide a downwardly-projecting flange may be used. 7 5 A T-bar is one example of such other fianged shape.

Whatllclaim as my-invention, and desire to secure by Letters Patent, is-

l. In a railway-car, the combination with a 8o metallic floor and end sill, of a safety-chain. eyebolt projecting through the end sill, an angle-bar attached to the floor, a strap surrounding the shank of the eyebolt and secured tothe vertical flange of said bar, and a nut or the like on the end of the shank of the eyebolt bearing against one end of the strap.

2. In a railway-car, the combination with a metallic floor and end sill, of a safety-chain 9o eyebolt projecting through the end sill, of a anged bar secured to the ioor and having a downwardly-projecting ange, a strap surrounding the shank of the eyebolt and having its edges secured to said' downwardly- 95 projecting iiange, and means for securing the shank of the eyebolt in said strap.

In testimony whereof I, the said ANDREW CHRISTIANSON, have hereunto set my hand.

ANDREW CHRISTIANSON.
