REME A. BEAUSEJ' OUR, OF NEW YORK, N. Y., ASSIGNOR TO STANDARD VARNISH WORKS, OF ELM PARK, PORT RICHMOND, STATEN ISLAND, NEW YORK, A CORPORATION OF NEW YORK.

CONSTRUCTION OF METAL DOORS.

Specification of Letters Patent. Patented Mar. 18, 1919.

Application filed. July 15, 1914. Serial No. 851,121.

To all whom it may concern:

Be it known that I, REME A. BEAUSEJOUR, a subject of the Crown of GreatBritain, and resident of the borough of Richmond, in the city and State of New York, have invented a new and useful Improvement in the Construction of Metal Doors, of which the following is a specification.

This invention relates to an improvement in the construction of metal doors, with the object in view of providing a hollow door which will be rigid. light, durable, and impervious to sound.

A further object is to provide a metal door which is quickly assembled, and cheap to manufacture.

A still further object is to provide a construction for a metal door which will permit the use of a hard grade of asbestos lining, without the use of any intermediate filling for supporting the shell of the door.

A practical embodiment of my invention is represented in the accompanying drawings, in which- Figure lrepresents a front elevation of a part of a metal door, a portion of which is broken away to show the parts more,

clearly below, i v

Fig. 2 represents a longitudinal section taken in the plane of the line AA of Fig. 1,

Fig. 3 represents a longitudinal section of a modified form of rail used in the construction of the. metal door,

Fig. 4 represents a perspective view'of a portion of the rail used in the construction of the door shown in Figs. 1 and 2, and

Fig. 5 represents a perspective view of a portion of the rail used in the construction of the door shown in Fig. 3.

The metal door of my improved structure when completed is made up to represent doors having stiles with top, bottom and middle rails, as now in common use.

In the drawings, I have shown only a portion of a door, of which the stile is denoted by 1, the top rail by 2, and the middle rail by 3. It will be understood that the other stile, not shown, will be constructed like the stile 1 and the bottom rail, not shown, will be constructed similar to the top rail 2.

The top rail 2.is constructed of channel bars denoted by 4, 5 and 6, which extend from the stile 1 to the opposite stile (not shown).

Each of the channel bars is formed with a bottom 7 side walls 8, 9, which side walls recede at a point 10 toward each other to form a recess 11in each wall.

The channel bars 4 and 5 are spaced apart with their channels facing each other so that the recesses 11 therein will be in position to receive a strip of hard grade asbestos 12 which extends into the. stile 1 and forms a filling or lining for the rail and a part of each stile. The channel'bar 6 is placed with its bottom 7 adjacent the bottom of the channel bar 5 so that the joint formed by the bottoms 7 of the channel bars 5 and 6 serves to stilfen the rail 2 as well as form a welding post.

The middle rail 3 is constructed of channel bars 13, 14, 15 and 16, which are similar in form to the bars 4, 5 and 6, and extend a distance into the middle portion of the stile l. The bars .13 and 14 are arranged with their bottoms adjacent, and the bars 15 and 16 with their bottoms adjacent, both of which form posts for the welding operation. The bars 14 and 15, with their'recesses, form a pocket for the reception of a strip of hard asbestos 17 which also extends into the stile 1 thereby forming a lining for the middle rail and a portion of the stile.

The extremities of the bars 6 and 13 which extend into the stile 1 have their recesses in position to receive a strip of'hard asbestos 18 passing downwardly thereby forming av lining forthe stile. I

;The extremity of the bar 16 with its recess which extends into the stile, serves to receive one end of a strip of hard asbestos 19 which passes downwardly through the stile to the bottom rail (not shown).

To secure the asbestos lined panel 20 in its position in the door between the rails 2 and 3, I provide a molding 21 formed from a single piece of metal crimped or swaged into the form shown in cross section in Figs. 2 and 3. This molding 21 is provided with a longitudinal recess 22 for the reception of the panel 20. The outer edges of the molding 21 are crimped to form recesses 23, 24, which crimped edges are arranged to fit snugly against the edges of the walls 8 and 9 of thechannellbars 6 and 13.

To cover and hold the several bars with their respective strips of hard asbestos, I provide a shell 25 of thin sheet metal, the inner edges of which are turned inwardly and secured in the recesses 23, 24, of the molding 21. The manner of securing and Welding the shell 25 to the channel bars is well known and will not be described specifically herein.

In the modified form of channel bar shown in Figs. 3 and 5, the walls 26, 27, are pro-- vided with longitudinal ridges or beads 28, 29, Which'serve to stiffen the walls of the channel bar and also form recesses forthe reception of the strips of hard asbestos used as the lining for the door. The bars are used in a similar manner in the construction of the door, as previously described in Figs. 1, 2 and at. I

NVhile I have described the door as having stiles, it will be understood that the extremities of the channel bars, together with the vertical and horizontal strips of hard asbestos and the shell form'the stiles.

It will be seen that the channel bars are arranged horizontally in position in the door with the maximum amount of hard asbestos recessed between the bars, which arrangement when incasedwith the shell, presents a door which is hollow, rigid, light and durable. i

The door constructed with this particular asbestos lining is also rendered impervious to sound as well as presenting a hard and solid surface for theshell.

It is evident that slight changes might be resorted to in the form, construction and arrangement of the several parts without departing from the spirit and scope of my invention; hence I do not wish to limit myself to the particular structure herein de scribed, but

WVhat I claim is:- v 1. A metal door comprising channel bars having the flanges of the ad acent bars op positely disposed, said flanges being propresence of two July, 1914.

videdwith longitudinal recesses, horizontally and vertically arranged asbestos lining nal recesses, an asbestos lining loosely interposed between saidbars withcertain of its edges supported in said recesses for forming the rails of the door, vertically arranged asbestos lining strips supported in said recesses adjacent thereto for forming" the stiles'of the door, and a sheet metal shell covering and securing said bars, lining and strlps together. 'f I 3. A metal door comprising horizontally arranged channel bars having the flanges of the adjacent bars oppositely disposed, I said flanges being provided with lo-ngitudinal recesses, an asbestos lining loosely interposedbetween sa1d bars with certainQof 1ts the rails of the door, vertically arranged asbestos lining strips supported in said recesses adjacent thereto for forming the stiles of the door, a panel molding adapted to lit-between said bars, and a sheet metal shell'covering and securing bars, lining and strips"to- I gether'and locking the molding within the rails and stiles.

In testimony, that I claim the foregoing as my invention, I have signed my name in witnesses, this tenth day of Witnesses:
