'FLOOR OR WALLl SCREED.

Application filed April 28, 1915.. Serial No. 24,570. ma .1

To all whom tm/1y concern.'

Be it known that I, THoMAsY Z. MERRITT, a citizen'of the UnitedStates, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and a i will consist of few and simple parts so that manufacture will be convenient and economical, and which may be readily applied to the walls, partitions 0r floors of buildings without the use of nails or screws, for use as supports for wood or metallic casings, wall-strips or other like yparts employed in finishing the interior of buildings.

. The invention consists of the novel construction, combination and 'arrangement of parts as described herein and claimedfand as illustrated in the drawing, it being understood that changes in form, size, proportion and material may be made within the scope of the claim without departing from the spirit of the invention or sacrificing any of its advantages.

In the accompanying drawing` which forms a part of the application, igure l is a broken away view showing a part of an upright wall or partitionof a building with the screeds mounted therein.- Fig. 2 is a planl view showing a part of a wall or partition with the screeds mounted therein, the view .being in transverse section, a portion of a wall-strip being added. Fig. 3 is a diagrammatic view showing a metallic sheet or plate used as a holder for the block or pillow. Fig. 4 is a front view showing the block or pillow mounted upon the plate. Fig. 5 is a transverse section on line 5 5 of Fig. 4. Fig. 6 is a view showing the screed applied to a building wall or partition, as a support for a wall-strip. or casing, said strip or casing, the plaster and wall or partition being in section.

Referring now to the drawing for a more particular description, numeral 7 indicates a block or pillow which may be constructed of wood, metal or any other suitable mate;-v rial adapted to operate as a support and as a retainer for nails or screws. It is preferably of rectangular form, of uniform thickness, and eachV of its sides is inclined Specication of Letters Patent.

inwardly fromthe backtofthe front, an thereby providing the /inclined'facets a.

Numeral 8 indica-tesv a rectangular metallic plate which may be incised on parallel lines o c and' lines c c, the parts between said lines being bent outwardly on lii'ies Z) b, inwardly of two opposed edges, to form recesses d (Fig. 5) and to form the flanges or clasps 9, their inclination with reference to the plate corresponding to the shape or inclination of the facets@ of vthe'block 7, and the, plate is provided, near its edges with apertures l0, the remaining part of the plate or that-part between the flanges` and recesses d preferably being imperforate. The block... is disposed on the imperforate part of the plate above recesses d with two of its inclined. sides embraced by the flanges or clasps 9 which operate to maintain 'the block between the rows yof apertures l0.

In operation, they screed is attached to. the wall 11 bv use of plaster of Paris 12 or other adhesive materialy by pressing the plate 8 against the wall, theplastic adhesive being compressed between the wall and said platel so that it will, in part, move forwardly through apertures 10. If' plaster of Paris is used it will soon become dry and firm and the device will be securely held to the wall.

The screeds may be-disposed in alinement as shown in Figs. 1 and -2, their thickness being substantially equal to the plaster 13 which is then applied to the wall. Since the area in plan of the plate is greater than that ,of the block, thel plaster will cover a considerable part of the plate, and will also cover the inclined sides of the blocks so that they will be firmly held by the plaster. As shown in Figs/2 and 6, a rail, wall-strip or casing 14 may be secured tothe screeds by keepers 15, and the screeds provide an adequate support therefor.

Among some of the advantages to be derived by use of the screeds it'may be stated that, where brick, stone, tile or cement are used for the walls or partitions, the conven-v tional channels-or recesses usually provided' therein for containing anchor-blocks or strips may be dispensed with, which results in a saving of'time and labor. Also the parts employed in constructing the screeds are'few, and they may be manufactured conveniently at, comparatively, a limited cost.

yat

plates being` formed outwardly of said lflanges with apertures to permit a passage therethrough of a part of said adheslve portions, a plurality of ber-,blockseach being disposed upon a plate between the flanges thereof, and a layer of plastic material surrounding said blocks and leaving a part of each block exposed In testimony whereof, l have aiiiied my signature in presence of two witnesses.
