MAURICE LACHMAN, OF NEW YORK, N. Y., ASSIGNOR TO UNIVERSAL ELECTRIC WELDING COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW.YORK.

RAILING, GATE, GRILLE, 800.

Application filed March 10, 1917.

To all whom it may concern:

Be it known that I, MAURICE LACI-IMAN. a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Railings, Gates, Grilles, &c., of which the following as a specification.

My present invention relates to the construction of metallic railings, gates, grilles, partitions and other structures of a similar character such as may be used to subdivide space.

The object of the invention is to provide a construction which may be readily made in any design desired and a cheap strong structure obtained.

A further object is to provide a structure which, if desired, may have the appearance of a wooden section while at the same time maintaining the strength, durability and fireproof qualities of metal.

A still further object is to provide atubular structure for the above purposes, the parts of which have square corners and of such construction that any desired design or relation of the parts may be attained in a simple, cheap and efiicient manner.

The invention consists in the improved construction of railings, gates, grilles and similar structures hereinafter more particularly described and then specified in the claims.

In the accompanying drawings, Figure 1 is a front elevation of a section of railing constructed in accordance with this invention in one of the many designs in which it may be made up.

Fig. 2 is a vertical cross-section taken on the line 2-2 of Fig. 1.

Fig. 3 is a horizontal section taken on the.

line 33 of Fig. 1.

Fig. 4 is a front elevation of one of the two complementary plates used in the construction.

Fig. 5 is an edge elevation of one of the spacing members used in the form shown in Fig. 1.

Fig. 6 is an enlarged cross-section taken on the line 6-6 of Fig. l and shows the manner of spacing the complementary plates apart and locking them together to complete the frame.

Fig. 7 is an enlarged transverse section Specification of Letters Patent.

Patented Nov. 8, 1921.

Serial No. 153,807.

through the strip from which the combined spacing and locking member is formed.

Fig. 8 is an end view of the plate shown in Fig. 4:.

In Fig. 1 of the drawings a section of a structure which may be used as a railing is illustrated, it being understood that the section may be extended to any desired length by adding thereto either by using greater length of material or joining other sections to it in any desired manner. Also it will be understood that the invention hereinafter described might be applied to the construction of gates, grilles, partitions and other like sections of any desired dimensions and design.

1, 1 indicates two complementary metal plates forming the opposite faces of the sections and are )referably stamped or cut from a sheet of metal and of any desired size.

Certain portions of the material of each of the plates 1, 1 are removed intermediate the outer edges to form a plurality of openings 2. The openings in the two plates register with each other and they may be formed by a simple stamping operation in a press having suitably formed dies.

The shape and number of the openings 2 as well as their arrangement might readily be varied to meet any required condition of design or appearance. In the design shown vertical members or pickets 3 are provided connected with cross connecting rails 4.

It will be understood that the plates 1, 1 may each be made up of a number of sections if desired, instead of being in one piece as shown.

The two plates 1, l are spaced apart by spacing members 5 preferably formed as continuous metal strips each following the contour of each opening 2. The spacing members are also preferably provided with two spaced apart preferably continuous projections 6, 7 upon which the plates 1, 1' seat. The spacing members are by preference strips of metal rolled with the projections 6 and 7 integral therewith and each strip is bent to shape so as to follow the contour of the opening and the ends joined together at 8 by butt welding them. When placed in the openings in the plates the members 5 space the plates apart and form a continuous wall thought to be obvious.

about the opening, the free edges 9 beyond the projections 6 and 7 projecting through beyond the plates. These free edges are then turned over in a press by means ofsuitable dies or otherwise whereby the plates 1, l

are clamped to the spacing members by means of the turned over edges 9 and the projections on the spacing members.

Preferably a similarly shaped spacing member 11 is provided along the outer edge of the plates to close the upper space of the upper rail and a similar member may be provided along the bottom of the lower rail and along the outer edge of the end uprights or pickets.

1f desired the outer spacing member 11 may be welded or brazed to the plates 1 and 1 to hold it securely in place, the members 5 in the openings 2 being held in place without such welding or brazing being necessary.

The simplicity of manufacturing sections according to this construction as well as the flexibility for great variety of designs is p All that is necessary is to stamp out the two plates according to the desired design, bend the rolled strips 5 to shape to meet the contour of the openings and after inserting them in placetogether with the spacing members forming the outer walls, turn over the edges 9 by any suitable pressing operation.

If desired to simulate a wooden railing the sections may be grained or enameled to meet the requirement and any one or more of the openings filled in with a cane or other anel.

It will be understood that my invention is not limited to the exact arrangement. as

shown and described but the construction may be widely varied without departing from the scope of the invention as expressed in the appended claims.

What I claim as my invention is:

1. A metallic structure of the character described comprising complementary metal plates having portions removed to form uprights and connecting rails and spacing members inserted between said plates and forming side Walls around the openings formed by the removed portions, said spacing members and complementary plates being locked together.

2. metallic structure of the character described comprising two complementary metal plates having a plurality of openings intermediate the edges and flanged spacing members interposed between said plates and forming walls around said openings, said plates being locked between pairs of flanges on said spacing members.

. 3. In a metallic structure of the character described, the combination of two complementary metal plates having a plurality of openings and spacing members having pro- 'ections u on which said side. )lates seat said spacing members forming walls around the edges or said openings and having flanges bent over on tothe outer surface of c said plates.
