To all whom it may) concern:

Be it known that I, THOMAS Z. Mnnarr'r,

a citizen of the United States, residing at' Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Floor or Wall Screeds, of which the following is a specification.

This invention relates to an improvement in a floor or wall screed, and has for its object, broadly, to provide screeds which 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 or floors of build-- ings without the use of nails or screws, for use as supports for wood or metallic casings, wall-strips or other like parts employed in finishing the interior of buildings.

The invention consists of the novel construction, combination and arrangement of parts as described herein and claimed, and as'illustrated in the drawing, it being under- .stood that changes in form, size, proportion.

and material may be made within the scope of the claims 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, Figure 1 is a broken away view showing a part of an upright wall or partition of a building with the screeds mounted therein. Fig. 2 is a plan view showing a part of a wall or par tition 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 illow. Fig. 4 is a front view showing the lock 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.

Referrin I now to the drawing for amore articular escription, numeral 7 indicates a Elock or pillow which may be constructedcof wood, metal or any other suitable material adapted to operate as a support and as a retainer for nails or screws. It is preferably area in of rectangular form, of uniform thickness,

and. each of its sides is inclined inwardly from the back to the front, and thereby provlding the inclined facets a.

Numeral 8 indicates a rectangular metallic plate which may be incised on arallel lines 6 c and lines 0 c, the parts etw een said lines being bent outwardly on lines 6 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 a of the block 7, and the plate is provided, near its edges with apertures 10, 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 blockv between the rows of apertures 10.

In operation, the screed is attached to the Wall 11 by the use of plaster of Paris 12 or other adhesive material by pressing the late 8 against the wall, the plastic adhesive ein'g compressed between the wall and said plate so that it will, in part, move forwardly through the apertures d and 10, said adhesive engaging and adhering to the rear face of the block 7 where it passes through the apertures d and engaging the inclined surfaces (1, after passing through the apertures 10, so that in addition to the block 7 being held in operative position by the flanges 9 and asan auxiliary and independent fastening means the said, block 7 is held in operative position by the actual physical engagement of the plastic adhesive to the block itself. The engagement of the adhesive with the block 7 is shown more par ticularly at Fig. 6. 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'lheri applied to the wall. Since the plan of the plate is greater than that of the b ock, the plaster will cover a considerable part of the plate, and will also, in conjunction with the plastic adhesive, cover the inclined sides of the blocks so that they ,will

be firmly the adhesive and the plaster- As shown in Figs. it and 6, a rail. wall-strip, or casing it may be secured to the scrceds by keepers 5 1.5, and the screeds provide an adequate support tl'icrcfor.

Among some of the iul'vantages to be derived by use the screcds it may be stated that, where brick, stone, tile or cen'ient are used-for the walls or partitions, the coni'itional chani'iels or recesses usually prol' thc'rein'for containii'ig anchor-blocks trips may be dispct edawith which re- Msults in 'asaving of time and labon Also the parts cnu'iloyed in constructing the nomads ar' "Few and they may be inanut'av turrd convei'iici'itly at, "colnpacrativcly, a lin'iitcil cost,
