As a convenient way of explaining the invention it will be described as embodiedforuseinfreightcarsoftheboxcartype.

lt is known practice to provide a box car with a steel lining which is spaced from the car wall and is provided with spaced perforations which receive locking fixtures mounted on the ends of crossbars used to support or con- Secondary features relate to means adopted to reduce weight and present wooden contact surfaces to the lading.

'I'he design is such that the locking and adjusting means lie wholly within the dimensional limits of an end projection of the beam, thus avoiding interferencev with and damage to lading, and permitting two similar beams to be mounted side by side and in contact when a second is needed to reinforce the rst.

Some cars have apertured posts (either fixed or adjustable) in lieu of the perforated lining above mentioned.

lThe invention can readily be adapted to connections of beams or the like to such posts, the problem being basically the same. Indeed the invention can be used wherever it is desired releasably to connect the ends of a beam to apertured parallel supports n selected positions. As a rule such beams are horizontal, and the desired directions of adjustment of the ends after attachment are likewise horizontal, but the invention is obviously not limited in either respect. The composite structure of the beam is not claimed in the present application but forms the subject matter of a divisional application Serial No. 94,160, led May 19, 1949, now Patent 2,514,229, issued July 4, 1950.

The perforations,which are alined in horizontal and vertical rows, comprise a circular center 12 with ydiametr-ically opposite horizontal rectangular extensions 13'.

I'he beam proper is compodte andcomprises a pressed steel shell 14 8-shaped in cross-section and two wooden inserts 15. The central web 16 of the shell 14 is-at the neutral-axis of the beam and hence can be lightenedby a rowof perforations 17 without loss of strength. Proofthe steel. componentof rimmed flanges 18. The rims 1 9 ofV flanges 18 are sunk in rebates cut in the inserts 15, so that the wooden inserts form the load-contacting surfaces of the beam. Through bolts 21 (see Figs. 3 and 4) whose ends are countersunk vclamp the 15 to the shell 14, i. e. against the web The end housings are conveniently constructed of plate by welding pressed or forged sections. The components welded together are two side plates 22 otiset toward each other at 23, an interposed connecting web 24 with olset 25 and a J-shaped tie member 26 which connects the extreme ends of the side plates 22 (see Figs. 2,3 and 5).

The end housings are welded-to shell 14. The side plates enter slots 27 in web 16 and engage theinner faces of llanges 18, `to which they are welded at 28 (see Figs. 4 and 7). y The web 24 engages web 16 and is welded thereto. 'Thus the end housings are virtually integral with the shell 14 of the beam.V .The wood inserts 15 are clamped to the shell and stlen the same but'oter comparatively little direct support to the end housings (see Fig. 3).

The vertical dimension of side plates 22 is materially less than the depth of the beam (see Fig. 3) and the horizontal dimension between the outer faces of plates 22 is considerably less than the width of the beam (see Fig. 2).

Hinged to block 33 on horizontal pin 34 is a locking'V arm 35. This has a hooked end 36 of a cross-section. (see Fig. 5) such as to tit any of the holes 12, 13 on plate 11. Slidable longitudinally in a guide formed in the upper part of block 33 is a bolt 37 with a crossbar 38 in its end, so dimensioned that the end of the bolt will pass througha second hole in plate 11 and when turned will engage behind that plate. A lateral handle 39 serves to turn and thus lock the bolt.

There are identical littings at the two ends of the beam. See Fig. l.

It will be observed that the nuts 32, bolt 37 (when locked) and arm 35 (when engaged) are all between theplanes'denedbythe twosidesrufacesandthetop andbottomsurfaeesofthebeam. 'Ihepossibletravelof 1f desired, me mm sz can be eliminated as shawn in Figs. 8 and 9. In this view parts similar to those in Figs.

The' ends' of the journals'29a are/substantially llushwithy the outer faces of plates 22a arr/d have hexagonal sockets' 41 by which the screw may be turned.

Operation In placing the beam it is held with its ends slightly above the desired position and the arms 35 are swung up so that the ends 36 start into appropriate holes 12, 13. The beam is then lowered until arms 35 engage crossmember 26, whereupon the bolts 37 are protruded and turned 90'. 'Ihey enter' the holes next above those entered by the arms 35. The screws 31 may then be turned to advance thefbeam into engagement with the lading.

The beaml locks at its end/to the plates so as to be held against relative motioni'in/ny direction. The beam may thus be placed above an', object and act to hold it down.

The screws afford progressive horizontal adjustment of hingedtothebeamonatransverseaxis,soastoswing yinto sustaining engagement with the beam-as its hooked end enters an aperture in the support; andfa bolt movable in a path approximately parallel with the hooked member when the latter is in such sustaining engagement, said bolt being adapted to enter, when projected, another aperture. in the support and thereby inhibit disengaging motion of the beam and hooked member.

2. In a load-sustaining device lfor engagement with a 10 support having a series of apertures, the combination of a beam; a housing mounted at the end of the beam to form a continuation thereof; a traversing block guided v in said housing to move ina direction transverse to the beam; force multiplying means within said housing for producing such motion; a hooked member hinged to said traversing block on a transverse axis so as to swing into sustaining engagement with the housing as its hookedend enters an aperture in the apertured support; and a bolt movable on the traversing block in a path approximately .20 parallel with the hooked member when the latter is in such such extent relatively to the spacing of the supporting i perforations that precise setting of the beam may always be had. `If needed, a .second lbeam may be set behind andy forced against the first to reinforce it. f

The construction of the composite beam is an important feature. The S-shaped shell 14 is of pressed steel and of engagement, said bolt being adapted to enter another aperture in said support, when projected.

3. In a load-sustaining device for use with a support having a series of apertures, the combination of a beam;

a housing mounted at the end of the beam to form a consuch form that the metal is effective to the fullest extent,

providing a beam with the maximum practicable section modulus in both transverse directions.

With the beam positioned as described' the llanges 18 give strength to resist buing. stresses or other forces acting in a horizontal direction. Similarly the rims 19 give strength to resist vertical loads. The perforations 17 in the web 16 reduce weight without impairing strength because theymre substantially at the neutral axisfor either dirletioii'of loading.

f e wooden in serts bearing against anges 18 and under 19 and being bolted together through the web 16 at 40 intervals throughout the length of the beam, as indicated at 21 in Figs. 1 and 4, are etective as load-bearing components of the composite beam. Not only do they resist bending moments imposed on the composite beam, brit also they resist compressional and torsional stresses and f resulting deformation such as might otherwise result in the thin steel section of the 8shaped shell 14.

In addition to the above structural aspects the wooden inserts are the load-contacting portions of the beam.

Since the end housings are welded to the core, a durable and very rigid structure results.

'I'he member 35, when engaged in the perforated plate on the side wall of the car, or when engaged in a similar recess in a column, will resist loads in any direction transverse to the beam, except upward. It will act in tension in the event that the end of the beam tends to separate from the wall or column. The bolt 37 is loaded in shear, by stresses transverse to the beam in any direction. This bolt holds the end of the beam against upward motion and supplements the related member 35.

Moreover, when the head 38 on the end of the bolt 37 is engaged behind the perforated plate the handle 39 is at its limit of motion or nearly so. Hence, the bolt 31 may react in tension under certain circumstances. 'Ihe fact that all components of the end tttings lie within the projected area of the end of the beam makes it possible to assemble two beams side by side and in contact with one' another.

'Ihe concept may be variously embodied and may be used' for many purposes. 'I'he embodiment above described in detail is intended to be exemplary. 'Ihe scope of the invention will be detined solely by the claims.
