LATH STRUCTURE Filed Feb. 11. 1929 Patented Mar. 22, 1932 PATENT JULIUS KAHN AND HERBERT E. WHITE, OF YOUNGSTOVYN, OHIO, ASSEGNORS T TRUSCON STEEL COMPANY, OF YOUNGSTOWN, OHIO, A CORPORATION OF MICHIGAN LATE STRUCTURE Application filed February 11, 1929. Serial No. 339,085. g

The object of the present invention is to provide as an article of manufacture, a lath structure for walls, ceilings and the like that will constitute an efiective support and back 5 ing for the plaster, and while providing for the proper keying of the plaster material, will reduce the amount of such material necessary to a minimum, while producing a satisfactory wall structure.

In the accompanying drawings:

Figure 1 is a front elevation of a portion of a lath structure made in accordance with the present invention.

Figure 2 is a sectional view on the line 2-2 of Figure 1.

Figure 3 is a perspective view of a portion of the lath structure with the plaster in place thereon.

Figure 4 is a vertical sectional view on the line 4.4 of Figure 1.

Figure 5 is a detail perspective view of one of the staples showing its application.

Figure 6 is a rear elevation illustrating a staple after it has been clinched.

In the embodiment disclosed. a backing sheet 7 is employed. Preferably this sheet is made up of a number of plies of material, and consists of a backing ply 8 that is rela tively heavy and rigid, so that it constitutes the main body of the sheet.

There is a facing sheet 9 of material light in weight and these two sheets are secured together by an interposed waterproof layer 10 that not only constitutes the adhesive between the two outer plies, but acts to prevent moisture from the wet plaster reaching the rear supporting ply 8.

The sheet 7, as a whole, is provided with rows of elongated depressions 11, the open sides of which are on the side of the sheet having the light facing material 9. As will be clear by reference to Figure 1, these depressions or pockets 11 are arranged so that those in each row are disposed end to end and those of one row are staggered with relation to those of the next. As a consequence the sheet is stiffened against bending transversely of the pockets, that is to say the walls of the pockets constitute sectional reinforcing ribs, and by the overlapping relation the forcing ribs on the rear of the plaster body section of one rib bridges the space between the ends of the sections of the others.

Located on the outer face of the backing sheet, to-wit, that face carrying the light' ply 9, are wires or rods which we term lathrods. These are designated 12. Each rod 12 extends longitudinally along and over the pockets of one of the rows and is fastened by staples 13 located between the ends of the adjacent pockets, the staples being driven through the backing sheet and having prongs 1% that are clinched beside each other as shown in Figure 6. i

This structure is nailed or otherwise fastened to the usual studding, and plaster as 15 (see Figure 3) is then applied. By reason of the fact that the rods preferably lie directly against the backing sheet, a relatively thin coat of plaster is sullicient and at the same time effective keys are secured by the plaster entering the pockets 11 and surrounding the portions of the rods that extend over the same. More than that the plaster that enters the pockets forms thereby short reinand these ribs being staggered act as stiffeners for the plaster layer and indeed for ing material for the plaster.

From the feregoin it is thought that the construction, operation and many acvantages of the herein described invention will be apparent to those skilled in the art with- 0 out further description and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing fromthe spirit or sacrificing any of the advantages of the invention.

What we claim, is V 1. A plaster supporting structure C0111- prising a backing sheet having elongated depressions forming open sided elongated pockets in one side of the sheet,'and lath rods located outside the sheet and secured to the sheet and extending longitudinally 7 over the open sides of the pockets.

2. A plaster supporting structure comprising a backing sheet having rows of spaced apart elongated depressions, thedepressions of one row being staggered with respect to adjacent rows, forming open sided elongated pockets in one side of the sheet, and lath rods located outside the sheet and secured 'to the sheet and extending longitudinally over the open sides of the elongated pockets.

3. A plaster supporting structure, comprising a backing sheet having spaced elongated open pockets, lath rods located outside the'sheets and extending along the face, of the sheet and longitudinally over the elongated pockets, and fastening means located .between the ends of the elongated pockets and securing the rods to the sheets.

4. A plaster supporting structure, comprising a backing sheet having rows of elongated open pockets, the pockets in each row pressions of one row being staggered with respect to adjacent rows, lath rods extending longitudinally along the rows and located lengthwise over 'the elongated open sides of the depressions, and fasteners securing the rods to the backing sheet.

8. A well structure comprising a backing sheet having rows of'elongatedpockets, the

pockets of each row being located end to end in spaced relation and being staggered with respect to the adjacent rows so as to bridge the spaces between the adjacent rows, and lath rods located outside the sheet and extending longitudinally along the rows of pockets and lengthwise over the elongated open sides of the pockets.
