' 3 Claims. (01. 25-118) -1 The present invention relates to new and useful improvements in stencils for finishing the walls of a building and more particularly to a stencil or marking a cement finishing surface 'of a wall to represent the bricks and mortar joints of a brick wall. c

An important object of. the invention is to provide a finishing stencil of this character in-- cluding ribs on the inner surface of the stencil to match and fit in the imitation mortar joints of imitation brick building blocks to hold' the stencil firmly against the wall while a finishing surface of cementis applied to the surface of the wall.

Alfurther object of the invention is to provide a stencil of this character having a handle at its upper edge for holding the stencil against a wall, the upper and one side edge of the stencil being positioned forwardly ofgthe plane of the stencil to prevent marring of the previously applied finishing cement and providing an adjustable stop pin or gauge at'the upper edge of the stencil adjacent the handle to prevent tipping of the upper edge of the stencil inwardly by pressure applied to the handle.

A still further object is to provide a device of this character of simple and practical con- I vstruction, which is efiicient and reliable in use,

relatively inexpensive to manufacture and otherwise well adapted for the purposes for-which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure l is a rear perspective view of the stencil;

Figure 2 is a front perspective view thereof; Figure 3 is a vertical sectional view, and Figure 4 is a front elevational view of a modifled stencil design;

Referring now to the drawings in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numeral 5 designates the stencil frame generally which is preferably constructed of light gauge sheet metal of rectangular form and formed with openings 6 separated by horizontal and vertical bars 1 and 8 substantially in the form of a grate construction to form the openings 6 of a size and shape corresponding to the size and shape of the exposed surface of the bricks. of a wall and with the bars .1 and 8 corresponding to the mortar joints of the'wall.

Theupper edge 9 and one side edge 10 f thestencil frame are offset forwardly of the plane of the central portion of the stencil to form flanges positioned outwardly at the upper andside edge of the frame'while the opposite side edge of the frame is formed with a forwardly extending flange I I "Ahandle I2 is secured to the upper flange 9 in a forwardly projecting position.

The rear surface of horizontal and vertical bars I and 8 are formed with rounded ribs l3 while. substantially sharp ribs I 4 project rearwardly at the perimeter of openings 6.

The bars I and 8 form the openings 6 of a size and shape of a full brick as shown at I 5 and of half bricks as shown at IS, the outer ends of the half brick openings I6 projecting outwardly beyond the outer ends of the full brick opening l5, and the marginal rib I4 is omitted from the outer end portions of the half brick openings l6 as shown at Me in Figure 1 of the drawings.

The invention is used by placing the stencil frame 5 against the outer surface of a cement block wall I! and with the ribs l3 and I 4 positioned in the imitation mortar joints IS on the outer surface of the block. A finishing coating of cement I 9 of a suitable color is then spread over the surface of the stencil to work in the openings l5 and Hi to thus provide an imitation brick finish for the surface of the wall.

The flanges 9 and I0 space the stencil frame from the previously finished surface of the work to prevent marring thereof and the outwardly projecting ends of the half brick openings I6 which are free of ribs on their inner surfaces enable matching of the half brick openings as upper edge of the stencil by pressure applied to the handle.

In the operation of the device, the stencil frame 5 is placed against a building wall constructed of building blocks having imitation brick mortar joints l8 in the surface thereof and with the ribs I3 and I4 seated in the grooves. Cement 7 into the openings I5 and 16 to form an brick:-

3 of a desired color is then spread over the outer surface of the stencil frame to work the cement imitation brick finish on the wall.

The raised flanges 9, ID and II on the stencil frame prevent the finishing cement from spreading onto the previously finished portion of the wall as well as on the unfinished surface adjacent flange H and raised flanges 9 and I0 prevent contact of the stencil frame with the previously finished surface to avoid marring the same when advancing the stencil to anew position.

The sharpened ribs Id at the marginaledges of the stencil openings enable the stenciltoflt' flatly against the wall, even though the block mortar joints are not of uniform thickness;

Figures 1 and 2 illustrates thejnventionhaying;

the brick simulating openings l5 and IB of a length greater than that of a standard brick, while Figure 4 illustrates a stencil 20 having its openings in view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantagesof the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary. I

- It is to be understood, however, that even though there is herein-shown and described a preferred embodiment of the invention the same is susceptible tocertain changes fully comprehended by the spirit of the-- invention as herein described and: the sc'ope of the appended claims. Having described the invention, what is claimed as new-is:

l. A wall finishing stencil comprising a sheet metal frame of grating construction simulating the bricks and mortar joints of a brick wall, ribs on the rear surface of the frame matching the mortar joints of the'wall, raised flanges at the upper edge and at one side edge of the frame 21 corresponding to the standard size spacing the flanges from previously finished work, and a forwardly projecting flange at the other side edge of the frame stopping the spreading of finishing cement applied to the frame.

2. A wall finishing stencil comprising a, sheet metal frame of grating construction simulating the bricks and mortar joints of a brick wall, ribs on the rear surface of the frame matching the mortar joints of the wall, raised flanges at the upper edge and at one side edge of the frame spacing the flanges from previously finished work, a handle on the upper flange, a stop pin adjacent the handle. projecting rearwardly of the frame to prevent tilting of the upper edge of the frame, and a forwardly projecting flange at the othersid'e of the frame stopping the spreading of finishing cement applied to the frame.

3. A wall finishing stencil comprising a sheet metal frame of grating construction and including horizontal and vertical bars simulating the mortar joints of a brick wall, ribs on the rear surface. of the bars adapted for seating in the imitation: mortar joints of a Wall constructed of imitation brick building blocks, and marginal V-shaped' ribs on the rear surface of the frame seating in mortar joints of the blocks for enter-- ing joints of various'widths, said frame including openings-representing courses of full and half bricks, the outer ends of said half brick openings of one course extending outwardly beyond: the outer ends of the full. brick openings of an' adjacent course, and. said V-shaped marginal rib being interrupted at. the. outer ends of the half brick openings.
