Before explaining in detail the present invention, and the method or mode of operation embodied therein, it is to be understood that the invention is not limited in its application to the details of construction and arrangement of parts illustrated in the accompanying drawings, since the invention is capable of other embodiments and of being practiced or carried out in various Ways.

ology or terminology employed herein is for 'the purpose of description and not of limitation, and it is not intended to limit the invention beyond the terms of the several claims hereto appended or the requirements of the prior art.

In the drawings I have illustrated, by way of example, invention in connecting with the inspection of metal, suoli as highly finished sheet steel. The sheet steel is, preferably, loaded and shipped by freight car to its destination in relatively heavy units or packs, and, preferably, in units approximating ten tons where a full capacityload is carried in the car. The metal sheets, in the case of sheet steel, are preferably stacked on edge and bound or braced together in unitary packs by means of adjustable binders carrying pressure devices as shown and describedin my co-pending application Serial N o. 137,- 867, filed September 27, 1926. At its destination, the car is unloaded by means of a portable ten ton capacity stack lifter which is moved into position within the car to straddle the pack, and which lifts the entire pack as a unit from the car floor onto the lift platform of a ten ton capacity industrial lift truck. The stack lifter and truck are preferably constructed in accordance with my co-pendinfT applications Serial Numbers 133,374,1i1ed september s, 192s and 118,584, filed .I une 25, 1926, respectively. The pack of metal sheets is propelled out of the car and transferred, without lifting the pack from vthe platform of vthe truck, to a portable transfer platform or buck, such as the buck illustrated in the accompanying drawings,

lwithout requiring the use of a crane or other mechanism for effecting the, transfer.

Figs. l, 2 anc. 3 of the drawings show the apparatus above described, in position with respect to the portable transfer platform or buck of this invention to effect the transfer of the pack S provided with adjustable binders B from its position upon the lift platform L of an industrial truck T to the transfer latform or buck shown as a whole at K. 'Illia buck comprises a base .or supan application of the present porting structure c onsisting, preferably, of a pair of longitudinally extending truss members or angle bars 10, preferably "IT- shaped in cross-section mounted upon leg supports designated as a whole at 20, the truss members and leg supports being spaced apart in parallel relation a sufficient distance to permit the lift platform of 'an industrial truck'with a pack of sheet metal thereon to move into position between the truss members and leg supports.

Each truss member l10, has an inwardly extending horizontal flange 10a and an outwardly extending horizontal flange 10b. Each member 10 is likewise provided with a vertical flange 10c, somewhat wider than either of the horizontal flanges.

The leg supports 20 each comprise a vertical channel 21 having ay central web 21a which is positioned' back toback with the V.vertical flange 10001:' the longitudinal truss member and `connected therewith by means 0f rivets or the like 22. Each leg support also includes a metal bar 23 bent into substantially U or V-shape providing a horizontal foot portion 23a which spans the space between the flanges of the vertical channel 21 at the base thereof, and two upwardly extending outwardly flared portions 23?) terminating in bent end portions 23o positioned in parallelism Vto the horizontal flange 10b of the longitudinal truss member 10. In order to form a rigid construction f the metal bar is connected with the verl-.ical

channel adjacent the foot portion 23a by means of rivets 24 and the outwardly extending ends or flanges 23o of the bar are connected with the horizontal flange 10a by rivets or the like 25. -To provide a Arigid supporting means for the pack of metal, the leg supports are each braced by means of an inclined channel member 26 having a web 26a positioned back to back at its upper end with one of the flanges of thevertical chan,-

`nel21by means of rivets 27; A substantially horizontally disposed angle bar 28 serves to connect the lower end of the vertical channel 21 with lthe baseof the inclined bracing channel 26, the angle bar being rigidly connected with the web portions of the two channel members by means of rivets 29. If desired, the langle bar 28 may be provided -with holes 28a to receive the bolts, screws or the like to detachably connect the leg supports to the floor, to prevent any accidental vmovement of the longitudinal trusses and supporting legs of the buck K. It will be noted that the web 26erl of the inclined channel 26 is positioned back to back with the inner face of one of the flanges of the vertical channel 21 and that the outer end ofone flange of the angle bar 28 is also positioned back to back with the web of th@ inclined .channel 26, the opposite end of` the angle bar being also positioned back to back 1,soo,155

with theinner face of the flange of the vertical channel 21 with which the upper end of the channel-26 is connected. From the foregoing it will be seen that the supporting members of the inspection platform or buck K are quite substantial andpractically immovable upon the floor.

In order to support the pack of metal in position between the longitudinal truss members of the buck, a series of longitudinally spaced slide bars are provided, these slide bars being indicatedas a whole by the numeral 30 and comprising, preferably, substantially U-shapedchannels 31 and 32, the

web portions of which `are positioned back to `back and secured together by means of rivets or the like 33 to'form an integral structure. Connected with each of the channect the gusset plate with the channels 31 and 32 and rivets or the like 37 are provided to secure the plate 36 in position between the flanges 34a and 35a of the angle bars 34 and 35, respectively. It will be seen that by Arigidly connecting together the channels, angle bars and gusset plate or web member, that an integral construction is provided which is of ample strength to support a pack of sheet metal, the constituent sheets of which may be positioned on edge and maintained in an inclined position, the pack resting against the flat faces 345 and 351) of the back Iber 36. The rivets 33 serve to rigidly conl rest. It will be lnotedthat the lower horizontal flanges 31a and 32a of the channels 31 and 32,' respectively, are adapted to -rest upon the top surface of each of the longitudinal truss members 10. As will be seen in Figs. 1 land 2,A preferably threesuch slide bars 3() are provided, and these bars are adapted to be interposed between the cross members of the pallet P.

In order to prevent the acci'dentalslipping A or displacement of the sheets upon the slide bars 30, short thin strips jofv wood 100 or any other inexpensive relatively soft mate.

rial may be placed upon the top flanges of the/,channels of the slide bars so that the lower edges of the sheets of the pack S rest thereupon, the weight of the 'pack causing the constituent parts thereof to bite into the wood and prevent the accidental slipping of thesheets upon the slide bars.

In order to support the forward end of the pack and prevent its accidental displaceu buck,- locking It will therefore `bers 4l and 42 and ment from its osition upon the platform or ogs, shown as a whole at (Fig-7),) are mounted upon the slide bars so as to comprises a 0 d pair of angle plate 41 and 42 provide with right angularly disposed ianges 41a and 42a respectively. The outer end of each of the flanges being turned in or bent back upon itself to provide oppositely disposed inwardly extending horizontal flanges 416 and 426, respectively, these last mentioned flanges or end portions being positioned in parallelism` to the right angularvly disposed flanges 41a and 42a. The forward Iend or-pack engaging portion of. each of the members 41 and 42 of the dog, is angularly disposed with respect to the memprovide outwardly and upwardly inclined ianges 41a and 42a, respectively. In order to draw the members 41 and 42 of the dog toward one another to cause their respective parallel flanges to grip the horizontal flanges of the channels 31 and 32, a bolt 43, having a nut 44, is provided.

be seen that the dog is adjustable along the slide bar so that it may be moved into position to engage the forward end of any pack ofJnetal which may be supported by the buck.

oreover, it will be seen that the depth of the channels 31 and 32 forming the slide bars is less than the depth or thickness of the transverse wood members of the pallet so that the slide bars may be moved into position between the bottom of the pack and the top surfaces of the truss members 10.

.` If it is desired, thin blocks or strips of wood `over against the back ofI this invention may 1n positlon upon may be positioned upon the top o the longitudinal truss member 10 so as to be interposed between it and the free end of each of the slide bars 30 when said bars are moved into position as shown in Fig. 4. While to use such strips orblocks of wood is not essential, nevertheless, by employing them, the sheets of the pack are given an initial tilt in the direction of the back supports or rests so that when the binders B are removed from the pack the sheets will tilt rests of their own acor but little efort is cord, (see Fig. 5),

part of the inspector to ac- .required on the complish this.

The portable inspection platform or buck t be used as follows, where the metal is shipped in packs bound or braced in accordance with my above mentioned co-pending application.

.The longitudinal truss members 10 which, as previously described, are mounted upon the improved leg supports, are first placed the Hoor and spaced apart in parallel relation so as to permit the lift platform of an industrial truck, supporting the pack ofsheet metal -with its attached e adjustable toward and from the `fback rests C. Each of the locking dogs 40 flanges 34 adjustable binders,I to move into position therebetween. The angle bars 28 of the bracing means are then detachably connected with the floor of the inspection room to prevent any relative movement of the truss members and leg supporting structure. It will be seen (Fig. 3) that when the platform L of the truck T, with its load thereupon, moves into position between the members of the buck, that the platform L is in its upmost or elevated position and that the space between the lower edges of the sheets of they pack S and the top surface of each of the truss members 10 is greater than the thickness or depth 0f the channels 31 and 32 forming the horizontal pack supporting means for each slide bar 30. This permits the several slide bars to be moved or slid from the position in which they are shown in Fig. 3 to the position of Figs. 4 and 5, whereby said slide bars span and bridge the space members y10 and serve as longitudinally spaced supporting means for the pack when it is lowered into position to be supported by the buck. Any desired number of slide bars 30 may beemployed although in the present instance three such bars are shown. These bars are preferably interposed between the transverse or lateral wood members of the pallet P and the transverse adjustable binders `B and properly spaced so as to support the pack of sheets adJacent its ends and central portion, when the pack is lowered into position and transferred from the platform of the truck to the slide bars. Before the pack is lowered, however, a thin wood strip 100 is placed in position upon the top horizontal flange of each channel 31 and 32 of the slide bars for the urpose previously described. The lift platform of the truck is then lowered so as to cause the lower edges of the sheets of the pack of metal to rest upon the wood strips 100 provided upon the slide barsV 30. The truck is then backed out from its position between the parallel spaced supports of the buck and from beneath the pack. The pallet members are then disassembled and removed from their position in engagement with the bottom edges of the metal sheets. The adjustable dogs 4() are then placed in position upon the slide bars and moved so as to engage the forward ends of the wood strips 100 and the front side of the pack of metal sheets, and locked in this position so as to form a stop or support for the pack of metal (see Fig. 5). rllhereafter the adjustable binders B are removed and the pack of metal.- sheets tilts of its own accord or is manually tilted so as to assume the position in which it is shown in Fig. 5. In this position it will be seen that the rear side of the pack is in engagement with the and 35 of the back supports or rests and' that the forward or front side yofthe pack is engaged, at spaced intervals,

by the adjustable dogs 4.0. In this position the operators may inspect the front face of eachof the sheets of the pack before they are removed therefrom to be `further inspected.

It will be seen from the foregoing that the pack of metal, which is removed from the freight car at its destination and propelled to the inspection section of a plant upon the lift platform of an industrial truck, is brought into cooperative relation to and placed upon the improved inspection platform or buck of this invention without the necessity of lifting the pack from the lift platform of the truck" during its transfer therefrom to the inspection platform or buck. The use of cranes or other hoisting mechanism for the purpose of handling the pack of metal4 during the inspection process is entirely eliminated. Furthermore, this invention enables the pack S having lbinders. B thereon to be deposited on the portable platform or buck and the binders removed without liftingthe pack in order to effect the removal of the binders.
