FFICE EDWIN G. FRANCK, OF DETROIT, MICHIGAN, ASSIGNOR; BY MESNE ASSIGNMENTS, T

I-IU'TCHINS CAR DELAWARE noorma COMPANY, or

DETROIT, MICHIGAN, A CORPORATION OF HOISTING ANCHORAGE FOR CAR ROOIFS Application filed January-3, 1927; Serial No. 158,707,

The invention relates to railway freight cars of that type known as box cars and which are provided with roofs pitched from a central ridge to the eaves. It is the object of the invention to provide an anchorage for hoisting apparatus used in loading and unloading the cars and one which permits of use at any desired point in the length of the car.

It is a further object to avoid any obstruction to the loading capacity of the car which as generally figured must be clear to the interior height of the sides of the body.

With these objects in view the invention consists in the construction as hereinafter set forth. t

In the drawings: Figure 1 is a cross section through a railway box car to which my improvement is applied.

Figure 2 is an enlarged cross section showing the hoist anchorage and Figure 3 is an enlarged section at right angles to Figure 2.

A are the carlines of the roof structure which are formed with pitched portions A on opposite sides of the car tion A which is substantially horizontal. Secured to these carlines and extending longitudinally of the car centrally beneath the carlines is a structural member B. This is preferably in the form of a channel member having its web at the top and provided on its opposite sides and at the bottom thereof with outstanding flanges B. C is a loop or yoke member having the inturned end portions 0' which hook over the outstanding flanges B. This loop is of sufiicient strength to carry the load to be hoisted and w ll transfer the hoistin g stresses first to the flanges B of the member 18 and then from said member to the ear-' lines. In Whatever position the loop is adjusted there will be one or more of the carlines for sustaining the load aided by the reinforcement of all of the other carlines to which the member B is attached.

"With the construction member B is entirely above the clearance height of the sides of the car and so forms no obstruction to the loading space. The memand a central porc as described the carlines and attached thereto, said beam being of inverted channel shape andhaving its base secured to a plurality of the said carlines, said beam being provided with outstanding flanges at the bottom of its sides and a loop provided with inturned hooks for en-' gaging said flanges adjustable thereon longitudinally of the car.

2. The combination with a car roof comprising a plurality of carlines extending transversely thereof, each carline having pitched side portions and a horizontal central portion, of a U-shaped beam extending centrally longitudinally of the car, said beam having its base secured to the horizontal portions of a plurality of said carlines whereby the beam is entirely above the clearance height of the sides of the car, said beam being provided with outstanding flanges, and a loop having portions slidably engaging said flanges and shiftable thereon longitudinally of the car.

In testimony whereof I afix my-signature.

EDWIN G. FRANCK.
