2 Claims. (Cl. 182-181) This invention relates to improvements in material stands, and particularly to material stands which are useful by building contractors and brick masons in the con struction of buildings.

The primary object of this invention is to provide a novel, simple, sturdy, strong, inexpensive, versatile material stand for supporting materials and for supporting runways upon which workmen can stand while erecting a building wall, such as a masonry Wall.

Other objects will be apparent from the following specication.

In the drawing:

Fig. 1 is a perspective view of a material stand used to support panels, planks or other members at an elevated position;

Fig. 2 is an enlarged detail view of a part of the device in side elevation;

Fig. 3 is an enlarged detail view in side elevation of a part of the stand;

Fig. 4 is a sectional view taken on line 4 4 of Fig. 3;

Fig. 5 is a sectional view of one form of panel used with the device;

Fig. 6 is a sectional View illustrating another form of panel usable with the device;

Fig. 7 is a vertical transverse sectional view of a modified form of the device.

Referring to the drawing which illustrates the preferred embodiment of the invention, the numeral lll designates a material stand adapted to support thereon planks or runway members 12 or panel members 14, or any other desired article.

Each of the stands is preferably formed of a pair of inverted U-shaped structural members, preferably formed of channel iron, to provide top members 16 and leg members 18. The channel member preferably has its web or central portion 19 positioned outermost and its flanges 20 projecting inwardly. In the formation of the members 16, 18 a channel member of desired length, preferably notched at 22, as illustrated in Fig. 2, at the flanges 20 thereof with a V-notch Whose edges are extended 90 de grecs to each other and at 45 degrees to the base of the i channel. The parts 18 are then swung to substantially 90 degree angle to the part 16 to bring the edges of the notch into abutting engagement to be welded together at 24 as by means of spot welds or butt welds. The legs 18 will be of the same length.

Two of the U-shaped

structural members

16, 18 are assembled together in spaced parallel relation. Thus a transverse structural member 26 of desired length connects the adjacent free end portions of the legs 18 of

adjacent units

16, 18. As here shown the structural member 26 is preferably a channel into which the bottom ends of the legs 18 fit, to be welded at 28 adjacent the upper margins of the opposite flanges of the channel 26. Thus, as best seen in Fig. 4, the welds 28 may include welds adjacent the free edge of each flange 20 of the legs 18 and welds 28' provided at spaced points on the web of the leg 18. The central part or web of the channel 26 provides a surface of large bearing area engageable with the ground to support the material stand firmly and to distribute the weight thereof, and the weight supported thereby, over a substantial area, whereby a solid support of the stand is provided, and, furthermore, the danger of penetration of the stand into moist earth under weight or load is reduced to a minimum.

The opposed U-shaped

structural members

16, 18 are also preferably interconnected by structural members 30, such as angleirons which are welded at 32 to the edges of the flanges 20 of the

parts

16 and 18 to extend parallel to the members 26 inwardly therefrom in a lateral direction and below the level of the top runs 16 of the crossmembers.

The proportions of the parts are preferably such that the spacings of the legs 18 of each of the U-shaped

members

16, 18 is at least equal to or preferably greater than the height of the legs 18, and the spacing between the opposite inverted

unit

16, 18 is preferably not greater than the height of the legs 18 and may be less than the height of said legs.

The stands 10 may be used in groups aligned alongside the wall of a building in selected spaced relation so as to support thereon a plank or planks 12 to form a runway or to support bricks, blocks, mortar, or like material, including mortar boards 14. The proportions of the parts are preferably such that at least two planks 12 may be supported side by side upon the stands 10 when the runs 16 of the stands are positioned perpendicular to the wall, as shown in full lines in Fig. l. It will be understood, however, that the stands 1t) may be positioned with their runs 16 substantially parallel to the wall so as to support a plank or planks 12', as illustrated in dotted lines in Fig. 1, parallel thereto. In the latter case the planks 12' will be substantially flush at their top surfaces with the top surface of the run 16, and will be retained by said runs against lateral sliding upon the stands.

The material stands will preferably be sold as a part of a set or system which will include panel members adapted for use as mortar boards, as illustrated at 14. These panels may be of any desired size and shape, and preferably will be protected by a surface sheath. In Fig. 5, I have shown a panel 34 which is formed of plywood and which has sprayed, painted or otherwise applied thereto, a continuous film or coating 36 of a synthetic resin material, such as cellulose acetate, styrene, epoxy, acrylic resin, or the like. The board may be sprayed, dipped or brushed for application of the resin film, or, if desired, a preformed film of plastic material may be adhered or cemented to the panel 34 to cover the faces and edges thereof.

It is not essential that plywood or solid wood be used, and any desired composition material having requisite rigidity and strength may be employed. Thus, as illustrated in Fig. 6, a panel 38 formed of fiberboard, preferably of the character commonly used for .insulation purposes, although matrials of more compact character, such as those known as hardboard, may also be employed. The panel 38 likewise is provided with a film or coating 4t) of synthetic resin material completely spanning the faces and edges thereof.

The panels 14 may be supported upon planks 12, 12'. Alternatively, a single panel 12 may be supported upon the top runs 16 of a material stand 10 to constitute the single stand or table for the support of mortar or other articles used during the erection of a building. For this purpose the panel 14 will preferably be of a length equal to or slightly greater than the length of the members 16 and will be substantially rectangular and preferably substantially square.

A modified form of material stand is illustrated in Fig. 7 wherein the legs 18' of the stand preferably diverge Patented Nov. 22', 1960 i downwardly Iand outwardly from the upper run or portion 16 of the stand The free ends of these legs are connected by members 26 and the upper portions of the two units are interconnected by members 30 in substantially thesarne manner described above. Suitable means may be provided to reinforce and brace the downwardly diverg'ing legs 18', and such means are shown in the nature of a bar 50 welded at 52 at spaced points to the upper portion 16' of each inverted U-shaped member 10, and

Vthence at its ends extending downwardly and outwardly 'at 54 in inclined position to pass below the members 30' and to extend'to the leg portions 18 at which they are welded at 56. In this construction the downward diverging relation'of the legs can accommodate nested or interfitting stacking of the stands, and the provision of the braces 5,0,.54 increases Vthe strength of the unit so that the stand lmay assuredly support heavy weights without danger of spreading of the legsv 18.`

While the preferred embodiments of the invention have been illustrated'and described'herein, it will be understood that changes in the construction may be made within the scope of the4 appended claims without departing from the spirit of the invention.
