Patented Apr. 25, 1933 UNITED STATES PATENT OFFICE CHARLES D. BONSALL, OF NEW KENSINGTON, PENNSYLVANIA, ASSIGNOB, TO I. H. KENSINGTON, PENNSYLVANIA, A CORPORATION OF MURPHY'COMPANY, OF NEW' PENNSYLVANIA LOAD 'LIFTING ARRANGEMENT Application filed April 18,

The device relates to improvements in railway freightcars which are provided with load supporting beams extending longitudinally of the car and positioned adjacent the roof. These beams are arranged for attachment of a load lifting device such as chains, ropes, ice'tongs, hooks, etc., which are used to move heavy articles in and out of the cars and move such articles around in the car or to place one part of the load over another, such as double decking automobiles. Such a device is shown in my Patent No.

1,7 02,961, February 19, 1929.

An object of theinvention is to provide a member capable of movement longitudinally of such a beam so that the point of. support or suspension of the load lifting device can be moved longitudinallyof the car to any convenient or desirable place.

Another object of the invention is to provide a cooperation between the above mentioned memberand the load supporting beam whereby a downwardly inclined pull exerted by the load lifting devicebinds the member upon the beam and prevents or retards its movement longitudinally of the beam.

- Another object of the invention is to provide an eccentric relation between the place of attachment of the load lifting device to the member and the point or points of contact between the member and the beam so that a downward pull of the device upon the member binds the member upon the beam. It may be desirable to have several such members upon each load supporting beam, for instance, to lift both ends of an automobile.

In the drawings: p

Figs. 1 and 2 show a typical load supporting beam applied to a railway car with one of my 'members mounted thereon.

Figs. 3 and ishow the relation between the carlin'e, load supporting beam and member. Figs. 5 and 6 show a modified construction wherein the member comprises two similar pieces riveted together. f Figs. 7, 8 and 9 show-a modified construction wherein the member is made of pressed steel plate. 4 i I Figs. lOand 11 show a modified construction wherein the place, of attachment of the 1929.

tion wherein the member is offset in a horizontal plane and preferably formed on, a radius in a horizontal plane.

Figs. 17 and 18 show a modified construction wherein the members are provided with two apertures or places of attachment of a load lifting device.

The load supportingbeam 2 is preferably positioned adjacent the center of the car or several such beams may be used spaced at intervals between the sides of the car. These beams are preferably attached to and supported by several carlines 3 and may also form the longitudinal roof frame members ofthecar, such as the ridge pole (as illus-. trated) or purlins 1. It is desirable that they extend the full length of the car and'have their opposite ends attached to'the opposite end plates 5 of the car. i

In the form of my invention illustrated the load supporting beam comprises a member preferably of an inverted channel section with the web 7 secured to the carlines 3, spaced, apart walls and oppositely projecting flanges 8 at each lower edge of the inverted channel beam. The member 9 is provided with oppositely projecting portions 11 slidably resting upon the flanges 8 of the load supporting beam and the members 9 are also provided with other parts 12.normallybelow and spaced apart from the flanges 8'so that the member 9 is normally movable longitudina-lly of the load supporting beam 2. Means are provided upon the member 9 for attachment of a load lifting device, such as a hook, ice tong or a rope or chain, which means is positioned between the parts 12 and is preferably formed with a depression to position or centralize the lifting device. When the member is used upon a supporting beam of inverted channel section, such as shown in Figs. 3 and 4, the means for attachment of the lifting device is positioned below the inverted channel so that a part of the lifting device may extend within the channel, thus reducing the vertical space occupied by the member and to give greater clearance between the member 9 and the supporting beam 2, and furthermore, the depression is preferably positioned below the inverted channel.

The parts 12 are in close proximity to the" beam, the member being provided with an aperture 17 for insertion of a hook or chain of load lifting device.

Figs. 7, 8 and9 show a modified form wherein the member 20 is made of a pressing having preferably depending flanges 21 adjacent the opposite side margins of the body of the member to stiffen it and preferably a corrugation 22 to stiffen the returned bends at the ends of the body which form the portions 23 for engagement with the flanges of the load supporting beam. A flared aperture 24 may be provided to accommodate the hook or chain of-a load lifting device. a Figs. 10 and 11 show a modified form wherein the member 27 ismade of two similar pieces secured together, each having a portion 28 resting upon a flange 29 of the load supporting beam 26. The member 27 is pro vided with an aperture 30 or other means for attachment of a. load lifting device, which is not below (i. e. eccentric from) the place of engagement between the portion 28 of the member and the flange 29 of the supporting beam, whereby a downward pull upon the load'lifting device causes the portion 28 to bind between the flange 29 and the upper web of "the supporting beam, thus retarding the movement of the member 27 longitudinally ofthe beam 2.

Figs. 12, 13 and 14: showa modified form wherein the member has

portions

36 and 37 resting upon the flanges"34c of the load supporting beam, which portions are provided with oppositely projecting lateral extensions 88 which accentuates the tendency of the member to bind upon the beam upon a diagonal pull of the load lifting device upon the member.

Figs. 15 and 16 show a modified form wherein the member 40 is provided with portions ll-'42 resting upon the flanges 44 of the load supporting beam 2 and the body part 43 of the member, that is, where the load lifting device is attached to it, is ofl center or eccentric from the places of contact of the 7 supporting portions 41 with the flanges of the beam so that a downward pull upon the load lifting device binds the member upon the load lifting beam and retards its movement longitudinally of the beam.

Figs. 17 and 18 show a modified form wherein themember 46 is provided with two apertures 47 or places of attachment for the load lifting device, eitherone of which is positioned eccentric from the place of sup= port of the member upon the beam.

Figs. 12 and 13 and also Fig. 15 show load supporting beams having lateral flanges for supporting the members which are upwardly inclined so that ice .tongs or similar means of attaching a load lifting device to the beam between the members will'notslipoif. Such beams are now in'gener'aluse. The-portions of the members whichbi'nd uponthe lower surfaces of the flanges of the beams" are preferably similarly inclined.

g The two piece members, such as shownin Figs. 5, 10 and 17, are desirable to facilitate application of the member to cars already equipped with a load lifting beam as' they can be riveted or bolted together after the lsjeparate members are associated "with the eam.

The accompanying drawingsillustrate the preferred form of the invention, though it is to be understood that the inventi'onis not limited to the exact details of construction shown and described, as it is obvious that various modifications thereof, within the scope of the claims, will occur to persons skilled in the art.
