FOLDING sUi=PoRT Filed May 10. 1926 ATTORNEYS.

' Patented Apr. 29, 1930 UNITED. STATES- CHARLES R. LET'IS, F JOHNSON CITY, NEW YORK V FOLDING Application filed May 10,

My invention relates to improvements in folding supports for tubs, platforms, and other containers. My object is to provide a light, simple and efficient foldable structure which will fold in compact form and take up little room, and at the same time, accomplish the foregoing results. With this object in view my invention consists in certain novel features of construction and arrangement of parts as will be hereinafter more. fully described and pointed out in the claims, reference being had to the accompanying drawings in which:

Fig. 1 is a perspective view of my device in operative condition.

Fig. 2 is a side elevation of my device in folded condition.

Fig. 3 is a side elevation of a part of my device in mounted position.

Fig. 4 is a plan view of a part of my device in mounted position. 7

Fig. 5 is a perspective view of the same part of my device.

The same reference characters denote like parts in each of the several figures of the drawings. In carrying out my device I provide a standard A occupying the center of the structure, preferably rectangular in form and having the sides 2, 2, 2, 2. Pivotally mounted on the sides of the upper portion of standard A are the rods or arms 3, 3, 3, 3, a rod being mounted on each side of the upper portion of the standard. The innerend of each rod is pivoted on side 2 ofstandard A by means of the bolt or pivot 4.

Mounted in the standard A, also arethe rods 3, 3, 3, 3, pivotally connected to the lower portion of the standard A- by means of the pivot 4. As a further part of my clevice I provide four legs, B, B, B, B,-being substantially rectangular in form and having the side surfaces 7, 7, 7 7. Mounted on the upper portion of the leg B and on the side of the leg in alinement with the side 2 of 5 standard A, I have the locking lug supports C, C, C, C, in form shown in Fig. 5, each locking lug support having a trough shaped chan nel therein, 8, and from which projects two parallel vertical side walls 9 and 9 of equal length, the wall 9 extending the length of the .ing lug support C. In this manner the desorroar 1 1926. Serial No. 107,884.

trough 8, and the wall 9 extending part of the length of trough 8, and its remaining portionbeing divided by a slot 10 into two parts, the upper part a being bent outward and projecting at a right angle to the wall 9 as shown in Fig. 5. Oppositely positioned to each other in walls 9 and 9 I have the openings 11 and 11, and through projecting walls a I have the openingl2. The openings 11 and 11 are for the insertion of a pivot bolt 13 I which extends through the openings 11 and 11 and through leg B as shown in Fig. 4:; and through opening 12 I have extending the bolt 14 through leg B as shownin Fig. 4. In the lower portion of each leg B, I have mounted in a similar manner a locking lug support 0. As a further featurein the construction of my device; through the outer end of each rod 3, I have a pivot opening 15 adapted to be engaged by the bolt 13 passing therethrough. In the 7 construction, having pivotally mounted therod on the standard A as before described'and the locking lug support C in its position on each leg B, I insert-the outer end of each rod 3, by raising it in the channel of trough 8 and mount it through the openings 11 and 11 in lug C. Through the opening 15, in the outer end of rod 3, the bolt 13 is mounted in the leg B, thusholrh ing theouter end pivoted in trough 8. l/Vhen thus connected and in this manner, thelegs B, B, B, are held spaced apart and in verticalpivoted engagement with the standard 'A. The parts are thus positioned when the device is in operative condition.

Vfhen I wish to fold the device I lift. up on standard A which raises the rods 3, 3, 3

out of rest in trough 8. This movement draws the legs B, B, B, towardsthe standard A. In

this raised and folded position, the standard 3 is raised to the limit of the length of the rods and the legs B, B,- B, drawn together as shown in Fig. 2. In this compact folded formation, the device is ready for transportation. When I wish to place the device in operative condition, I press down in standard A- which pushes out the leg members B, B, B, until the pivoted rods 3, 3, 3 rest again in trough-8 of the lockvice 1s ready for use.

Having thus described my invention what I claim as new and for which I desire Letters Patent is as follows:

1. A folding support comprising a central vertical standard rectangular in cross section, upper and lower outwardly extending metal arms pivotallyrnounted on each face of the rectangular standard, the arms secured to each face being disposed in vertical alinement, vertical legs pivotally secured to the outer ends of themetal arms, and a trough shaped rest mounted on one face of each leg in alinement with a corresponding surface of the standard, the outer end of each arm resting in its respective trough shaped rest.

2. A folding support comprising a vertical standard having plane surfaces thereon, a plurality of leg members associated with said vertical standard, each leg member having a sidein alinement with a plane surface of the standard, metal arms pivotally secured to a plane surface of the standard, trough shaped v legmembers;

rests secured to the leg members and adapted to receive the outerends of the metal arms and pivot bolts passing through the trough shaped members andthe outer ends of the arms for pivot-ally securing said arms to the 3. A folding support comprising a central vertical standard provided with plane surfaces, supporting legs associated 'fwith said vertical standard, each leg having a side in a n m nt wit a Pla e u fac of t t dard, metal arms pivotally secured to the plane surfaces of the vertical standard, trough shaped rests associated with the legs and extending inwardly toward the vvertical standard, a bracket member integral with each'trough shaped rest for engaging two surfaces of each leg member, means for securing the trough shaped rests tofthe leg members, and pivot bolts passing through the outer ends of the metal arms and the trough rshapedirests for pit 'otally securing the legs to the metal arms.
