SCREEN.

Application led'January 8, 1925. Serial N o. 1,234. Y l

To all whom t may concer/n.:

Be it known that I, WILLIAMN. CRorrEn, a citizen of the United States of America, residing at Lexington, in the county of Fayette andv Stat-e of Kentucky, have invented certain new and useful Improvements in Screens, of which the following .is a specification.

My invention relates to improvements i screens and screen construction.

An important object of my invention is to provide a screen with newand improved means for allowing ready removal or replacement of the netting.

Another object of my invention is the provision of a device of the above mentioned character with Va key member for locking the netting keepers in position. Another object of my invention is to provide a device of this character with improved means for pivotal mounting.4 Other objects and advantages of my invention will be apparent duringthe course of the following description. Y

In the accompanyin drawings which forma part of this speci cation and wherein like characters of reference denote like or corresponding parts throughout the same, Y

Figures 13 and 14 are detail views illustrating one mode of assembling the crossbar, and

Figure 15, is a similar view of another mode of assemblingthe cross-bar.

In the drawings wherein for the purpose of illustration isrshown a preferredA embodiv ment of my invention the numeral 16 designates a window frame of the usual construc-` tion which is adapted to receive the screen. This screen. comprises side, top, and bottom channel strips 17 which have their sides 18 bent inwardly at an acute .angle thereby lforming a substantially*inverted V-shapedvchannel with an opening at the top, or apexoi' the V. These Achannel strips are adapted to receive substantially V,shaped keepers 19l which fit snugly therein. The outer side 18 oil one ot' the side channel strips iscut away at both of its ends, as at 20, as is the outerside of the bottom channel strip.

In assembling, the netting is placed over yond the cutaway portion ofthe channell at one end, in order that the side keeper may be lslid in place. The key section 22 is sprung into place over the bottom keeper, and its end is bevelled to interlit with the end of the side keeper. When in this position, thekeepe'rs are positively locked in place, and may not be removed without first removing thefkeyy section. v

The keeper strips and key section are provided with openings 23 for the accommodation of a nail 24 or ot-her.implement to assist in removing them from the channels. The screen frame is strengthened by means of stay rods 25 which are provided at their ends with head portions 26.` The inner sides of the channels are provided with openings `or' the size of thestay rod, the sides ofwhich are slitas at 27 and struck upl at 28 in order to receive the head 26 of the stay rod. VWhen the rodsare in place, the struck up portions 28 are pressed back into their original position, as shown in Figure 14:, and the rodsV are locked in position.

In the form shown in Figure 15,` the large openings 30 open into the smaller openings 31, and when the rod isin position and the netting clamped in place the rod will be securely held.

A plate 32 is rigidly secured to the upper Aother stud, and these rods are connected by an internally screwthreaded coupling member 39. In the form shown in Figurel 4, the rod 38 is provided with an enlarged head 40 which engages a recess 4l in the coupling. rIhe coupling member will rotate 'freely on the rod 38 and will engage the threads on the rod 37 to move the same. It will be seen that rotation of the coupling will project the pivot bolts into the openings 42 and will lock them there until they are retracted by rotation of the coupling member.

In the form shown in Figures 5 and 6, the rod 38 is not positively connected to this coupling but has a reduced portion 43 which extends into the coupling, which abuts against the shoulder 44 formed by the reduced portion. In this form ofl my invention the coupling only serves to lock the bolts in their extended position. When it is desired to withdraw the pivot bolts, thecoupling is screwed onto the rod 37 until the rods fall apart, as in Figure 6, and the bolts may then be manually withdrawn.

A prop or support isformed by the rod 45 which encircles the upper stay rod adjacent one side of the screen and extends nearly to the bottom of the screen where it is bent upon itself to form an eye 46 and then eX- tends back to apoint adjacent the stay rod where it is twisted about itself and extended transversely of the screen parallel to the stay lVhen it is desired to'raise the screen, the

eye 46 is hooked over a nail or stud 46 to support the screen in its raised position. It will be seen that the prop will support both sides of the screen and cause it to hang straight although it is arranged nearly entirely on one side of the screen.

A chain 47 or the like is secured to the plate 32 in order that the screen may be hung up in a convenient location when not in use. A hook or catch 48 is secured to the window sill and engages an opening in the lower channel strip to retain the screen in its closed position. l

While I have shown and described the preferred embodiment ot' my invention it is to be understood that various changes Yin the size, shape, and arrangement of parts may be resorted to without departing from the spirit of my invention or the scope of the subjoined claims.

Having described my invention what I claim as new and desire to protect by Letters Patent is:

l. A `screen comprising substantially V- shaped channels, and substantially V-shaped keepers adapted to be slid longitudinally into said channels.

2. A screenv comprising substantially V- shaped channels, and substantially V-shaped keepers adapted to be received therein, said channels having certain of their ends provided with cutaway portions to allow insertion of the keepers.

3. A screen comprising substantially V- shaped channels,` and substantially V-shaped keepers adapted to be received therein, said channels having certain of their ends provided with cutaway portions to allow insertion of the keepers, one of said keepers terminating short ot the channel. in which it is received, and a key keeper section adapted to be arranged over said shortkeeper to complement .the same, and lock the keepers in the channels.

4. A screen comprising channels, the sides of. said channels being inclined towards each other, netting adapted to be arranged over the inner sides of the channels, keepers adapted to be arranged within the channels, certain of the ends of the outer sides ot the channels being cut away to allow insertion of the keepers, oney of said keepers terminating: short of the channel in which it is received, a key keeper section adapted to complement .said short keeper and lock all of the keepers in position, stay rods connecting the inner sides of the side channels. and a prop arranged adjacent one side of the screen and engaging both ends of the stay rodto properly support the screen.

5. A'screen comprising substantially V- shaped channels, substantially V-shaped keepers adapted to be received therein, said channels having certain of their ends provided with cutaway portions to allow insertion of the keepers, one ot said keepers terminating short of the channel in which it is received, a key keeper section adapted to be arranged over said short keeper' to comple- 115 ment the same and to lock the keepers in the channels, a sleeve secured to the upper channel, pivot bolts slidably arranged in the sleeve, and means to project said bolts and loc-k the same.

In testimony whereof I affix my signature.

WILLIAM N. CIOPPER.
