WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 357,267I dated February 8, 1887;

vApplication filed May 14, 1886. Serial No. 202,170. (No model.)

To all whom t may concern:

Be it known that I, YJOSEPH A. BRYAN, a citizen of the United States, residing at Prescott, in the county of Nevada and State of Arkansas, have invented certain new and useful Improvements in Window-Screens; and I do declare the following to' be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the'same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of. this specifica tion.

My invention has relationto windowscreens; and it consists in the novel construction and arrangement of its parts in connection with the attachments to the window frame and sash.

In the accompanying drawings, Figure 2 is a front elevation of a window, showing my screen and attachments; Fig. 1, a vertical sectional view of Fig. 2 cut through on the line x.

My screen consists of -;the.upper end piece, 1, lower end piece, 2, side pieces, 3, and center piece, 4. In the open space between the pieces are iron bars 5,or heavy Woven wire. Over this may be again placed, if desired, Woven Wire ne enough to keep out bugs, candle-ies, mosquitoes,- and the like. Thel said screen Cmay be tted to any window without interfering with the arrangementsof the sashalready in the same.

' The inner face of my screen works against the stay-strip7 or inner strip, a, of the Window-frame A, and is kept in place by an additional inner strip or stay-strip, b, between which strips it slides up and down. On the inner face of the upper and lower cross-pieces, 6 and 7, ofthe innersash,B, are secured plates 8, having the perforation 9, which plates may or may not be countersunk. On the inner face of the jambs of the window-frame A, and on their loose ends by the tassel 41-5.

screen (l are secured two loose pulleys, e e, on the staple 12. On the same edge of said crosspiece and at either end are secured springbolts 13, so situated that their locking ends are forcedinto the perforations of the plates c by their spiral springs. To the open ends of these spring-bolts are attached cords 14, which are passed under `the loose pulleys e e, and then over the loose pulley D, and united at A springbolt, 16, is passed through the lower piece, 2, of the screen, so situated and secured that when the sash B is down and the screen C is also down, the locking end of the said bolt is forced by its spiral spring into the perforation 9 of the lower plate, 8, and when the said sash is down and the screw is up the locking end of said boltis forced into the perforation of the upper plate.

My screen is-operated as follows: W'ith one' hand I take hold of the knob of the spring bolt 16 and withdraw it from the perforation 9 in the lower plate, 8. Atthesame time I pull on the tassel 15. This pulls the cords 14 and withdraws the spring-bolts 13 from the 4perforations 9 iu the lower plate, c. Then I push the screen up by means of the spring-bolt 16,-

lbut I prefer to use the additional bolt for greater safety.

I am aware of the'patent to Isardv et al., No. 272,884, wherein they use cords passing over pulleys to operate spring-bolts to'screens, and of the patent to Mitchell, No. 329,758, wherein he uses cords passing over pulleys to operate dogs to curtain fixtures, and I disclaim the construction contained in either of these inventions; but

WhatI do claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the window-frame A, of the screen C, additional stay strip b,

ICC)

perforated plates c d, secured to the inner face of the janibs of said window-frame, loose pulley D, secured to the lower face of the upper lintel of said frame, spring-bolts 13, secured to the upper edge of said screen and locking in said plates, loose pulleys e e, secured on the upper edge of said screen, and cords 14, having one end attached to the said spring-bolts, then passing under said loose pulleys e e, then over pulley D, substantially as shown and described.

2. The combination, with the window-frame A and sash B, of perforated plates 8, secured to the upper and lower pieces of said sash, the screen C, additional stay-strip, b, perforated plates c d, secured to the inner face of the jambs of said frame, loose pulley D, secured to the lower face of the upper lintel of said frame, springbolts 13, secured to the upper edge of said screen and locking in said plates, zo loose pulleys e c, secured on the same edge of Said screen, cords 14, having one end attached to each of said spring-bolts, then passing under said loose pulleys e e, then over pulley D, and spring-bolt 16, secured in the lower piece, 2 5 2, of said screen and locking in plates 8, substantially as shown and described.

ln testimony whereof I affix my signature in presence of two witnesses.

JOSEPH A. BRYAN.
