11 Claims. (Cl. 105-369) This invention relates to improvements in load partition beams of the type adapted for use in railway cars, trucks and the like and comprehends improvements in the disclosure of my copending application Serial No. 564,788, filed February 10, 1956, now abandoned. In the devices of the prior art it was sometimes found difficult to conveniently lift the beam sufficiently to withdraw the locating hook or books from the slot in the channel, or disengage the hook or hooks when the beam is under loaded conditions.

It is, therefore, an object of this invention to provide means to facilitate the use and application of a liftbar under lift wings on the supporting projection of the hook or between the head and the channel for releasing the parts when under loaded condition.

A further object of the present invention is to provide a head for a lading beam which embodies features which will prevent deterioration of the structure due to Wear and which will likewise have the capacity to resist breakage due to overloading.

Another feature of the present invention is to position the hook in line with the shank to eliminate eccentric load conditions on the book which might occur when placed otherwise.

A further object of the invention is to construct the supporting projection so that integral wings will project above the beam, this arrangement facilitating the control and removal of the head and beam by use of a lift bar.

These and other objects of the invention will more clearly hereinafter appear by reference to the accompanying drawings, wherein like characters of reference designate corresponding parts throughout the several views, in which:

Fig. 1 is an enlarged perspective of a head structure showing its association with a channel and with a lift bar in position for removing the hooks from the channel;

Fig. 2 is.an end perspective of the head structure of Fig. 1;

Fig. 3 is a view similar to Fig. 1 showing the lift bar under the supporting projection;

Fig. 4 is a perspective view of a head structure utilizing dual hooks;

Fig. 5 is a longitudinal section through a lading beam;

Fig. 6 is a horizontal fragmentary sectional view showing the structure of Fig. 5; and

Fig. 7 is a transverse section through a lading container showing a proposed arrangement of channels and lading beams.

In order to fully comprehend the nature and use of the invention, the vertical sectional view in Fig. 7 illustrates a lading chamber having the bottom 1 and side walls 2 provided with longitudinally extending horizontal supporting beams 3 formed with suitably spaced perforations 4. The lading beams 5 are shown with fixed heads 6 and sliding heads 7, the heads including the hook structures illustrated in other views for engagement with the perforations or elongated openings 4 formed in the outer faces or web of the channels 3. It is customary in devices of this type to form the beam structure shown in Figs. 5 and 6 of hollow metal and to provide each beam with a fixed head 6 and a sliding head 7, each of the heads being provided with similarly shaped parts. The fixed head 6 is shown as including a main body 8 having a shape and configuration to snugly fit within the end of the beam as defined by the walls of the hollow beam structure. This beam structure includes bottom wall 9, top wall 10 and side walls 11 and 12. The body 8 of the fixed head 6 is preferably welded within the adjacent end of a beam, as shown at 14.

In Fig. 5 the sectional view of the beam supporting channel 3 is best illustrated, this channel includiing the web .15 and upper and lower flanges 16 and 17, respectively. The web 15 is provided with spaced vertically elongated slots 4 in which the hooks projecting from the head extend. A supporting projection of the head nor: mally lies upon the upper surface of the upper flange 16 of the channel. The sliding head completing the lading beam includes the head 7 fixed to a shank 20 having inner guide rod extension 21. The shank 20 and the guide rod extension 21 project into a housing 22 having a reduced inner portion 23 with flanges 24 defining an inner closed end portion. The body 22 is provided with inner and outer flanges 25 and 26 which are snugly received within the walls of the beam to position the housing and the outer flange 26 is welded to the end of the housing, as shown at 27. A spring 28 abuts the inner end wall 27a of the housing and the inner face 27b of the shank and normally urges the sliding shank and head assembly outwardly within the limits defined by the slot 29 which receives the inner extremity 30 of the pin 31, the latter projecting through the bottom of the beam wall 9, the bottom of the housing 22 and into the slot 29 where it functions to permit the movement of the sliding head inwardly and outwardly.

Referring now to Figs. 1, 2 and 3, which disclose the sliding head carried on the shank 20, it will be seen that this head includes a vertical plate-like body shown at 35, this body 35 being formed as an integral part of the shank or welded thereto as desired. The body 35 has extending laterally therefrom above its center a horizontally positioned supporting projection 36 with a thick erred medial portion 37 (-Fig. 2) having a lower flat face 37a and lateral lift wings 38, the undersurfaces of which are upwardly tapered as at 38a to provide inwardly converging recesses 39 when the supporting projection is seating on the upper face of the flange 16, shown more clearly in Fig. 5. These recesses 39 provide an area in which to extend the working extremity of a lift bar or like tool indicated at 40, as shown in Fig. 3. In Fig. 3 the tapered end 41 of the lift bar is shown as projecting beneath a jacking wing of the head 36 and between the wing and top surface of the flange 16 of the channel for lifting the beam vertically to disengage the hooked extremity 45 of the hook member 46 from within the slot 4 in which it has been seated. The hook 46, Fig. 2, projects from the thickened medial wall portion 47 of the lower portion of the vertical plate-like body 35 fixed to the shank 20. The book 46 has its lower outer face portion 48 extending generally vertically while the upper portion of this outer face portion 48 of the book 46 is flat and inwardly inclined as at 49 to assist in the socketing and unsocketing of the structure.

Still referring to Fig. 2 it will be seen that the vertical plate 35 is relatively wide, closely approximating the width of the lading beam and it will be further noted that the central thickened portion 37 of the horizontal supporting projection 36 provides a relatively heavy strong supporting area and that the lift wings which extend laterally at each side of the medial portion and are defined in part by the tapered underfaces 38a, pro- 3 ject the full width of the vertical plate-like body 35. It will also be noted that the lift wings projecting laterally of the thickened medial supporting projection 37 are strengthened by a tapering of the thickened wall portion laterally and rearwardly to add strength to the structure and to give body to the .part engaged by the lifting tool or lift bar. It will be further seen from an inspection of the drawings that the shank of the head is positioned medially of the vertical plate 35 at the thick ened lower area 47 which supports the hook structure,

and that the shank is further positioned at the lower portion of the thickened portion 47 so as to be directly rearward of the hook structure.

Referring now to Fig. 4 it will be seen that the structure is generally identical with thedisclosure of Fig. 2 with the exception that a pair of hooks are provided and project from the lower spaced corners of the thickened medial portion 50 of the vertical plate 35. In this showing the lateral walls 51 of the thickened area 50 are generally tapered and merge with the hooks 52 and 53 which are positioned at each bottom of the lateral sides of the thickened portion. Hooks 52'and 53 are laterally spaced off center of the beamstructure, as is also indicated for the single hook in Fig; 6, allowing for greater flexibility when bracing a load. In the structure of Fig. 4 it will be noted that the thickened area 50 is somewhat increased over the thickened area shown in Fig. 2, although this may or may not be essential in accordance with requirements. Obviously where two or more books are provided, they are suitably spaced to engage the spaced slots 4 in the beams 3.

Referring to both forms shown in Figs. 2 and 4, it will be obvious that the thickened walls 47 and 5t) will abut the outer web faces of the channel when the lading beam is in position and that this thickened portion will thereby function to space the vertical jacking wings 54 and 55 outwardly from the web channel, as shown in Fig. l. The. location of the jacking wings 54 and 55 in spaced relation to the web 15 of the channel will provide an area in which to insert a lift bar 40, as shown in Fig. l, to shift the sliding head out of its recess or recesses in accordance with the type of head used, i.e. either single or multiple.
