US3820936A - Wall surfacing die with support and moving means - Google Patents

Abstract

This application discloses a process for forming a layer of masonry-like material on the outside of walls or panels. The process is carried out by using a die which is the same size as the area to be coated. The die is made up of a rigid outside frame with partitions extending between the sides and the ends of the frame. The partitions are rectangular in cross section and are laid out in a pattern which defines the outline of a masonry block of a constructed wall of brick or stone. The material of the partitions have the same thickness as the material to be placed on the wall and the frame of the die is provided with clamps in one embodiment of the invention. The clamps are suitable for clamping it to the panel. In another embodiment of the invention, the die may be supported on suitable supports and lowered into the material after it is placed on the panel or wall.

FIG. 2 is an enlarged partial side view of the die shown in FIG. 1;

FIG. 3 is an enlarged view of the clamp shown in FIG.

provide an im FIG. 4 is a side view of anotherembodiment of the invention;

FIG. 5 is a view of another embodiment of the invention.

DETAILED DESCRIPTION OF THE DRAWINGS Now with more particular reference to the drawings, the die shown in FIG. 1 is indicated generally at 10. It is made up of a frame having side members 12 and end members 11 connected together in a rectangular grid pattern in the preferred embodiment of the invention. The side members 12 have the lugs 16 welded to them and the lugs 16 have pins 25 which extend through slots 24 in the clamp arms 17 so that the clamp arms 17 can slide up and down on the pins 25. The upper end of the clamp arm has the axle20 extending therethrough. On

the inner end of the axle, the cam wheel 19 is fixed. On

the outer end of the axle, the crank 18 is fixed. The cam rides on lugs 16 and when the cam is rotated from the position shown in FIG. 3, the flange 23 of the clamp is forced against the bottom of the sheet panel 22 thereby clamping the frame to the panel In a typical example of the frame, the transverse members 14 may be 1 inch thick and three-eighths inch wide and, likewise, the longitudinal members 13 may be one-eighth inch thick and three-eighths inch wide.

In the embodiment of the invention shown in FIG. 5, the stencil form 110 is identical to that shown in FIGS. 1 through 4, with the exception that the partitions made by the transverse members 114 and the longitudinal members are approximately three-fourths as deep as the side members 111 and end members. Thus, there will be a space 125 between the longitudinal members and the lateral members 114 below each transverse member which will allow mortar to enter and form a continuous coating of the masonry material coating from one side of the panel to the other, or over the entire surface of the wall.

In the embodiment of the invention shown in FIG. 4, the frame of the die is indicated as supported on hydraulic cylinders by which the die may be raised and lowered. Thus a panel supported on the support table 131 may have the masonry material spread over its top surface, then the die 110 may be brought into place over top of the sheet of material and brought down into the masonry material thereby forming the masonry pattern. The material may then be struck off the top of the die.

In atypical example of the use of the embodiment shown in FIGS. 1 and 2, the die 10 will be clamped into place on top of panel 22. Then masonry-like material made up principally of Portland cement and aggregate will be placed over the top of the die and struck off flush with the top by a straight edge or suitable tool.

The masonry material can, of course, be put in place on the panel 22 before the die 1.0 is clamped to the panel.

In the embodiment of the invention shown in FIG. 4, the masonry material would be placed on the panel 131 and either leveled before lowering the die 110, or, it would be placed on the panel 131 and the die 110 lowered and the excess masonry material struck off from the top surface of the die by a trowel or the like.

Tabs 40 which may be sheet metal strips extend through slots 42 in panel 22 and have nail holes 41 for attaching to studding.

The foregoing specification sets forth the invention in its preferred practical forms but the structure shown is capable of modification within a range of equivalents without departing from the invention which is to be understood is broadly novel as is commensurate with the appended claims.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. A die to be used in forming a pattern resembling blocks ina layer of hardenable material on a building panel, I

said die comprising a frame in the form of a grid of relatively rigid material,

said frame being of a thickness of the desired depth of demarcations defining said pattern,

said frame further comprising laterally and longitudinally extending partitions defining grid openings through said die and being of width approximately equal to mortar joints in masonry walls,

said opening being of the size and shape of said blocks, I

said partitions having the thickness of the depth of the desired pattern,

means attached to said die for moving said die generally perpendicular to said panel and into engagement with said panel,

said die being adapted to be supported on a building panel with said openings in said die being filled with a plastic hardenable material,

said means for moving said die comprising means attached to said die and being adapted to be withdrawn from said material before said material hardens whereby said pattern is left in said material when said die is removed.

2. The die recited in claim 1 wherein said means attached to said panel comprises a fluid actuated cylinder.

Claims (2)

1. A die to be used in forming a pattern resembling blocks in a layer of hardenable material on a building panel, said die comprising a frame in the form of a grid of relatively rigid material, said frame being of a thickness of the desired depth of demarcations defining said pattern, said frame further comprising laterally and longitudinally extending partitions defining grid openings through said die and being of width approximately equal to mortar joints in masonry walls, said opening being of the size and shape of said blocks, said partitions having the thickness of the depth of the desired pattern, means attached to said die for moving said die generally perpendicular to said panel and into engagement with said panel, said die being adapted to be supported on a building panel with said openings in said die being filled with a plastic hardenable material, said means for moving said die comprising means attached to said die and being adapted to be withdrawn from said material before said material hardens whereby said pattern is left in said material when said die is removed.

2. The die recited in claim 1 wherein said means attached to said panel comprises a fluid actuated cylinder.
