MATERIAL-RACK.

Specification of Letters Patent. Patented Oct. 11, 1921.

Application filed April 12, 1919. Serial No. 289,604.

To all whom it may concern:

Be it known that I, GILES M. TURNER, a citizen of the United States, and resident of Milwaukee in the county of Milwaukee and State of Wisconsin, have inventednew and useful Improvements in Material-Racks, of which the following is a description, reference being had to the accompanying drawings, which are a part of this speclfication.

This invention relates to improvements in material racks, more particularly adapted for shop or manufacturing use in supporting various kinds of material.

It is One of the objects of the present invention to provide a material rack which is easily adapted for supporting material of various kinds and lengths. I

A further object of the invention is to rovide a material rack having means for orming a plurality of vertically and adjustably spaced shelves or rack bars for separately supporting difierent sizes and kinds of material.

A further object of the invention is to provide a material rack having foldable u right end members which may be folded w en the rack is not in use to occupy a minimum amount of space.

A further object of the invention is to provide a material rack having removable supporting legs to permit the use of the rack with or without the legs.

A further object of the invention is to provide a material rack having means for reinforcing the lower rack member and for locking the foldable upright end members in open position.

A furtherobject of the invention is to provide a material rack in which the lower rack member is adjustable as to length.

A further object of the invention is to provide a material rack constructed of commercial metal bars bent to desired shapes to form the rack.

A further object of the invention is to provide a material rack which is of simple construction, is strong and durable and is well adapted for the purpose desired.

With the above and other objects in view, the invention consists of the improved ma terial rack and its parts and combinations as set forth in the claims, and all equivalents thereof.

In the accompanying drawing in which the same reference characters indicate the same parts in all of the views:

Figure 1 is a perspective view of two of the improved material racks combined for holding long bar material;

Fig. 2 is a side view on a larger scale of a slightly modified form of material rack.

parts broken away to more clearly illustrate the parts; and

Fig. 3 is a vertical sectionalview thereof, taken on line 3-3 of Fi 2.

Referrin to the drawlng, the numeral 5 indicates t e transverse horizontal member of the improved material rack which is formed of two flat bars 6 and 6' of commercial metal overlapping each other and connected to ether by screws 7. The overlapped portions of the bars are provided with a plurality of screw openings 8 for adjusting the length of the horizontal member. The uppermost part 6 at 5' is offset downwardly medially of its length to position the outer end portion in the same horizontal plane as the other part of said horizontal member. The side edge portions of the opposite ends of the horizontal member are bent upwardly at right angles to form U-shaped bearing ends 9 to receive the lower end portions of foldable upright end members 10. Pivot bolts 11 extending through the bearing ends and the lower end portions of the upright end members connect said and members foldably to the horizontal member. The lower inner corners 10' of the end members are rounded to permit the fold ing inwardly of said end members, and the lower outer corners are projected outwardly to form shoulders 12 which bear against the horizontal member and prevent the end members from swinging too far outwardly. Said end members are provided with a plurality of spaced openings 13 for receiving transversely extending supporting pins 14 which support spacing rack bars or shelves 15 resting thereon. The said rack bars are provided with elongated slots 16 through which the end members extend. This construction provides for securely holding the bars on the end members and for preventing said end members from swinging outwardly under strain of load. Any number of bars may be used to form separate racks or shelves for supporting material in separate spaces and when thus used any number of racks may be used for supporting long material.

In many cases it Is desirable to support the material above the floor, and to do so legs 17 are provided. Said legs are also formed of commercial metal bars bent to a triangular shape as indicated by 18 with the upper end portions of the bars extending horizontally away from each other to form a fiat support 18 and then bent upwardly and inwardly toward each other to form clamping jaws 19.

The horizontal member 5 rests upon the flat supporting portion 18 and the jaws l9 engage the opposite edge portions of said horizontal member. A bolt 20 extending through the adjacent vertically extending portions 21 draws the jaws 19 into clamping engagement with the horizontal member 5 and forms a rigid and adjustable connectlon therebetween.

A reinforcing member 22 is provided which is adapted to rest edgewise upon the horizontal member with its opposite end portions entering the grooves of the U- shaped bearing end'9 and close to the inner edges of the upright members 10. The member 22 not only reinforces the horizontal member 5 but also locks the upright members 10 against accidental folding. The numeral 23 indicates bars of material supported by a pair of the material racks arranged in spaced relation.

From the foregoing description, it will be seen that the material rack is of verymsimple construction and is well adapted for the purpose described.

What I claim as my invention is:

1. A material rack, comprising a transverse member of flat commercial strip having its opposite side portions adjacent its ends bent upwardly to form comparatively narrow base stop portions and U-sha ed bearings, and end members also forme of commercial strip extending between the U- shaped portions and pivotally connected thereto and having shoulders formed on their pivoted ends which bear against the base portions to limit the movement of the end members, said pivoted connections permitthe transverse member to upright positions at right angles to the-transverse member.

3. A material rack, comprising a trans verse member having its opposite side portions adjacent its ends bent upwardly to form U-shape bearings, angular supporting legs clamped to the transverse member, end members pivotally connected to the U- shaped bearing portions and having projections which limit their outward movement, and spacing bars removably connected to the end members.

4:. A material rack, comprising a transverse member having its opposite side portions adjacent itsends bent upwardly to form U-shape bearings, angular supporting legs clamped to the transverse member, end members pivotally connected to the U-shaped bearing portions and having projections which limit their outward movement, and

spacing bars adjustably and removably connected to the end members and through which members the bars extend.

5. A material rack, comprising a transverse member having its opposite side portions adjacent its ends bent upwardly to form U-shape bearings, angular supporting legs clamped to the transverse member, a reinforcing bar positioned on the transverse bar and engaging the U-shaped bearing portions, end members pivotally connected to the U-shaped bearing portions and having projections which limit their outward move- I ment, and spacing bars removably connected to the end members.

In testimony whereof I aflix my signature.

GILES M. TURNER.
