Specification of Letters Patent.

Patented May 6, 1919.

Application filed June 5, 1917. Serial No. 173,060.

To all whom it may concern:

Be it known that I, ARTHUR E. RNNDLE, a citizen of Great Britain, residing at Philadelphia, Philadelphia county, and Sta-te of Pennsylvania, have invented and discovered certain new and useful Improvements in Metal WVindow-Sashes, of which the following is a specification.

My said invention relates to a method of maklng and assembling the component parts of metal frame structures, and to the structure thereof per se, and consistsin the novel steps of procedure of manufacture and combinations and arrangements ofparts in the structure hereinafter described and particularly set forth in' the accompanying claims.

The purpose of the invention is to produce a substantially jointless metal frame structure which will be free from attack by rust, corrosion, or other deterioration, due to the elements; one wherein the parts of the structure may be assembled in an easy manner, and in which the completed structure will possess the strength requisite for its purpose.

The invention is designed with special reference to window frame structures, to the end that the windows, when located in places inaccessible for painting, will not rust, and thereby avoid the expense which such painting entails and the extreme danger attend ing work of this character.

A window or sash that is made of rolled steel or cast iron, unless kept frequently painted, ru'sts and corrodes when exposed to the weather or air. that many of the steel windows in a building of modern construction are inaccessible from the outside without extreme danger, and con sequently it is diflicult to paint the exterior of these windows, with the result that they are often left unpainted, and in a remarkably short time will rust and deteriorate.

To overcome the above mentioned disadvantages, and also to save the heavy expense of this painting and avoid the danger as well, it is propsed to cover the outside or exposed surfaces of the sashes or windows with a non-rustable sheathing. And it is further contemplated to unite the elements of the frame, through the medium of the sheathing, in such a manner as to obtain a virtually jointless structure.

The invention is disclosed by way of illus- It is invariably the case tration in the accompanying drawings, wherein:

Figure 1 is a front elevation of a window sash.

Fig. 2, a vertical sectional view thereof on the line 2-2 of Fig. 1.

Fig. 3, a. horizontal sectional view on the line 3-3 of Fig. 1, and

Fig. 4, an enlarged detail view, showing the manner of applying the sheathing.

Referring to the construction in detail, and with like reference characters indicating corresponding parts, 5 designates the outside frame of the sash, constructed of any suitable angle-iron; 6 are the vertical muntins of T or I iron shapes; and 7 the horizontal pieces completing the inner parts of the frame structure.

The frame may be usual swinging section, or ventilator, comprising a rectangular frame 8, pivotally mountedv on the muntins 6, as at 9; and angle-irons 10 and 11 are secured to said swinglng section and one of the crosspieces 7, and, with the crossbars 12 and 13, provide the means for holding the swinging section, when closed, within the plane of the frame. Also, the two strips or bars ll are carried by said swinging section along the provided with the sides of the lower or outwardly swinging portion of said section.

The frame 5, muntins 6, and crosspieces are covered with a sheathing 15, of metal, that is applied thereto either by drawing, bending, or in any other preferred manner. Likewise, the exposed portions or flanges of the bars 12, 13 and 14 of the swinging window sections are covered with this sheathing, which is applied thereto as in the manner stated.

It will, therefore, be seen that all of the outer or exposed portions of the steel frame, or window, thus covered by this sheathing will be protected against rust, corrosion, or other deterioration due to the elements. And it will be obvious that this addition to the metal framework will rather augment the strength of the structure and add to its attractiveness, inasmuch as it is proposed to cover all those portions of the structure that are exposed.

The parts of the windov. or sash are as sembled in a simple and novel manner, to

wit, the outer frame 5 has the sheathing 15 applied thereto at the sides, top, and bottom 'in the manner stated. The flanges of the muntins are covered with the sheet metal, and in like manner the horizontal Ts and PS; and on each part the strip overlies the bar continuously for its entire length. The vertical muntins are perforated with apertures having cross-sections agreeing with the structure of horizontal parts of the frame to be received, and are then placed on a flat surface, preferably a large table or bench. The horizontal barsare then driven through these apertures and the whole inner frame secured to the outside frame of the sash by riveting or welding. The exterior steel of the structure is now entirely covered with a non-rusting sheet metal, and without a joint or seam, except at the ventilators; and in this respect applicant has accomplished what has heretofore not been possible with steel structures having mitered or other joints, which prevent the same from being covered in the manner he proposes, and, in like manner, with frames made where the horizontal pieces lie flush with the muntins, it is impossible to cover the bars with a continuous strip of metal.

I cept as may It is obvious that those skilled in the art may vary the details of construction and arrangement of parts without departing from the spirit of my invention, and I, therefore, do not wish to be limited to such details exbe required'by the claims.

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent is:

l. A rust-proof frame structure comprising a plurality of parallel metal members, strips of sheathing covering said members respectively for the length thereof, said sheathed members having perforations, a second plurality of members, non-rustable metal strips on said second members, and

said second named members passing through the apertures of the first named sheathed members and secured thereto, said sheathing providing an unbroken surface throughout the frame, substantially as set forth.

2. A rust-proof Window frame structure comprising an outer frame, a sheathing of non-rustable material on said frame, a plurality of muntins secured to said frame, sheaths of non-rustable metal on said mun tins, said sheathed muntins provided with perforations; a plurality of horizontal members, sheaths of non-rustablemetal covering said horizontal members, and said sheathed horizontal members passing through the apertures of the sheathed muntins and secured to said outer frame, said sheathing providing an unbroken surface throughout the frame, substantially as set forth.

3. A rust-proof window frame structure comprising an outer angle-iron frame portion, a plurality of angle'iron muntins secured to said outer frame, sheathing of nonrustable metal on said muntins for the entire length thereof, said sheathed muntins provided with alined perforations respectively; a plurality of horizontal members of angle-iron construction, sheathing of nonrustable metal on said horizontal members for the entire length thereof, and said sheathed horizontal members passing through the apertures of the sheathed muntins and secured thereto, said sheathing providing an unbroken surface throughout the frame, substantially as set forth.

In witness whereof I have hereunto set my hand and seal at Philadelphia, Pennsylvania, this 4th day of June, A. D. nineteen hundred and seventeen.
