.CORNER-PIECE FOR SCREEN-FRAMES.

To all whom 'it may concern:

Be it known that I, GILBERT E. FERRY, a citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Corner-Pieces for Screen-Frames, of which' the following is a specification.

This invention relates to improvements in corner pieces for screens or sinlar frames, and has for its object to provide corner pieces of this class having features of construction whereby the cost of manufacture may be reduced, but wherein a strong and convenient structure may be produced for use in efect-ually securing together the terminals of the vertical and horizontal strips of the frame.

Metallic sheets are generally employed in the manufacture of corner pieces of this class; they are formed so that they envelop more or less of the end portions of the strips. In their manufacture, the required forms are generally cut from integral sheets, and a loss of material has resulted on account of the comparatively extensive and angular forms required, when cutting the sheets. The herein described corner pieces, by reason of their construction are very convenient for mounting upon the ends of the strips, and may be manufactured from small portions of waste sheets or cuttings of no particular value for other purposes, whereby the cost of production is lessened, and an article is provided, convenient and eective for the purposes required.

With these objects in view the invention discloses a novel combination and arrangement of parts, as described herein, pointed out by the appended claims, and as illustrated in the accompanying drawing, it being understood that changes in form, size, proportion and minor details may be made within the scope of the claims without de parting from the spirit of the invention or sacrificing any of its advantages.

In the drawing, Figure 1 is a perspective view showing the terminals of a horizontal and vertical strip of an ordinary screen frame, before being secured together. Fig. 2 is a view of the same parts shown in Fig. 1, wit-h corner pieces mounted thereon em bodying my invention. Figs. 3 and l are `perspective views illustrating the construetion, separately, of the corner pieces shown Specification of Letters Patent,

Application filed October 18, 1909.

Serial No. 523,170.

in Fig. 2. Fig. 5 is a plan View of the upper side of a horizontal strip and the upper end of a vertical strip, the corner pieces being mounted thereon. Fig. 6 is a plan view of the lower side of a horizontal strip, the vertical strip being in section, and illustrating the employment of flanges, a part of a window frame, and a tongue usually employed in connection with slidable screen frames being added and in section.

Referring now to the drawing for a more particular description,

numerals

7 and 8 indicate, respectively, horizontal and vertical strips of a screen frame or other like device, and as is well known, grooves 9 are generally formed in the outer sides or faces of the vertical strips, extending their entire length.

At 10 is indicated a support or part of a window frame, a longitudinal projection, ridge or tongue thereon being indicated at 11, and in practice, when the parts of a screen frame have been assembled and operatively mounted, said screen frame is slidable, the tongues engaging within the grooves.

In order that the terminals of the horizontal and vertical strips may be effectively secured together, I provide the corner pieces indicated at 12 and 13. They are each L- shaped7 and may be constructed to advantage of sheet metal. Each has a flat body portion 14 adapted to have a seating upon the side of a horizontal strip; also each has a flat body portion 15 integral with and disposed in the plane of body-portion 14, adapted to have a seating upon a side of a vertical strip. Body portions 14 of the L-shaped corner pieces are provided with transverse 'upper and lower flanges, indicated respectively at 16 and 17. They are disposed substantially at right angles to these body portions, and are adapted to have seatings, respectively upon the upper and lower sides or faces of the horizontal strips. Body portions 15 of the corner pieces are provided with

flanges

18 and 19 disposed substantially at right angles to said body portions. Flanges 19 are adapted to have seatings upon the inner sides of the vertical strips. Flanges 18 are disposed substantially at right angles to body portions 15 and may have seatings upon the outer sides of the vertical strips adjacent to grooves 9, and they may have inwardly extending wings 2O tallic strips dis osed substantially parallel with said bo y portions l5, and are adapted to have seatings upon the oppositely-disposed walls 21 of said grooves 9.

In practice, the terminals of the horizontal and vertical strips of a screen frame may be effectively held together by use, singly, of either of the L-

shaped members

12 or 13, and it is not necessary that both be used. Where they are used in this manner, the members are secured upon the same side of the screen frame, the opposite side remaining blank. Where thin material is employed, however, it is an advantage to use both

members

12 and 13 conjointly. The preferred construction is to provide a width for flanges 16 equal to the space between the sides of the strips, as best shown in Figs. 2 and 5, these flanges having reduced or cut away portions to provide the inclined edges 22 intermediate flanges 18 and their free longitudinal edges 23, in which instance, flanges 16 may overlap, as plainly shown in said Fig. 2. This construction however, while adding materially to rigidity and strength as compared with lianges of less width which could not overlap, is not important. But where thin material is employed they may be constructed and disposed in a manner to overlap to advantage. It will be noted that flanges 16, as shown do not obtrude upon groove 9. It will be understood that corner pieces of this class must be so constructed that tongue 11 may have an unobstructed seating within and throughout the entire length of said groove.

In operation, body portions 15 of the L- shaped corner pieces are first seated upon the terminal of a vertical strip 8, and it will be held by means of flanges 1S and 19, also it will be seen that longitudinal wings 20 provide an additional holding means. I employ holdin members to connect the L- shaped memflrvers to the strips, as brads or nails 23 driven into the sides of strip 8 through openings 24 of body-portions 15. Horizontal strip 7 is then inserted between body portions 14 and is pushed forwardly until its front end makes yContact with the vertical strip, and at this time it is held between

flanges

16 and 17, and pins or

nails

25 and 26 may be driven into the horizontal strip through t-he respective openings 27 and 28, whereby the terminals of the horizontal and vertical strips will be securely fastened together. I

It will be seen that the herein described corner pieces may be constructed from meof small size, as compared with integral structures which envelop both sides of the horizontal and vertical strips. Also the parts as shown and described may be readily assembled, and may be conveniently secured.

Longitudinal wings 20 provide metallic portions which may make contact with longitudinal tongue l1, so that the screen may slide with less friction, and they provide an increased degree of rigidity for said flanges. I do not claim any novelty in the screen frame shown in the drawing. The herein described means are simply for securing the terminals of frame strips where they meet at right angles to form a corner of the frame.

' Having fully described my invention, what I claim and desire to secure by Letters Patent is,-
