To cti/l whom it may concrn:

Be it known that I, SAMUEL H. GARRETT, a citizen of the United States, residing` at West Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Window-Screens, of whichthe following is a specification.

My invention has relation to an adjustable and slidable window-screen, and in such connection it relates to the particular construction and arrangement of the same.

The principal objects of my invention are, first, to so arrange a window-screen frame as that the same when too large may be adjusted by any unskilled person to the size required and thereafter rigidly locked in the position given; second, to provide such 'a window-screen frame with means to permit of the ready connection and disconnection of a fleXible fabric thereto; third to form the members of the frame of plain bars and to provide certain of the same withclamping means to permit of the ready assembling of the bars into a screen-frame and of then separating for shipment, and, fourth, to provide the frame of a window for the screen-frame with means to permit of the holding of the same in any given position within the window-fraine.

The nature, scope, and characteristic features of my present invention will be more fully-understood from the following description, taken in connection with the accompanying drawings, forming part hereof, in which y Figure 1 is a vertical sectional View of a Window-frame on the line :c x of Fig. 2 and illustrating in side elevation a window-screen in operative position within the same embodying main features of my present invention. Fig. 2 is a horizontal sectional view of the window-frame and the Window-screen arranged therein on the line y y of Fig. 1 and also illustrating the manner of slidably connecting the window-screen with the windowframe. Fig. 3 is a detailview, enlarged, illustrating in side elevation the upper right-hand portion of the window-screen and also illustrating the manner of disengaging a portion of a flexible fabric therefrom and the adjustment of one member of the screen-frame for fitting the same to a window-frame. Fig. 4 is an end elevational view of Fig. 3. Fig. 5 is a detail view, enlarged, illustrating in crosssection one member of the screen-frame and the manner of connecting the flexible fabric thereto. Fig. 6 is a perspective view of a member of the screen-frame provided with clamps at each end. Fig. 7 is a perspective view of a portion of a guide for the screenframe and for holding; the same in any given position within the window-frame; and Fig. 8 is a detail view, enlarged, and illustrating in side elevation the left-hand upper corner of the frame with the fieXible fabric removed therefrom.

Referring to the drawings, a is a windowscreen consisting of the horizontal members a' and & and the vertical members a and a which, as shown in Figs. 3, 4, 5, and 6, are preferably rectangular and oblong in crosssection and consist of plain bars. As shown in Fig. 6, each of the vertical or side members a? and a of the screen-frame a is provided at its ends with a clamp b, forming a projecting eye ?1 into which when the frame a is to be assembled the horizontal or plain top and bottom members a' and a are slid.

In order to more securely connect the clamps b with their respective bars 00 and (t the same are provided with rectangular projections b@ engaging a groove a arranged therein. To render the screen-frame a, so formed, adjustable, it is only necessary to arrange one of the clamp-bars-for instance, the bar a -loose therein and to connect the other bars rigidly with each other by driving nails, staples, or other fastening means through the openings l) of the clamps b and into the plain bars a' and a Each of the bars a', a cfi, and w* is provided with a groove a into which the end of a fleXible fabric c-such, for instance, as mosquito-netting is placed and is held in position therein by a wire or cord d, as shown in Fig. 5. This cord d by being forced into the groove a simultaneously with the flexible fabric c draws the fabric taut over the frame a and holds the same securely connected therewith by means of glue or cement placed in the groo ve a prior to the introduction of the cord and fabric or by the intervention of nails or staples, which may be driven through the cord and fabric c into the frame a. One end of the cord d adjacent to the bar a is permitted to slightly project above the groove a so that the same may be easily clisengaged from the frame a by beng lifted out of the groove a in case the frame a is too large to be placed in the window-frame e, as shown in Fig. 1. This arrangement is only necessary IOO IIO

into the groove c' when the window-screen a, is placed on the market, in which instance one side of the flexible fabric c adj acent to the bar a'* will be left disconnected to facilitate adjustment of 'the member at If the screen-hame a is too large, the bar a is shifted inward, as shown by dotted and full lines in Fg. 3, until the frame is brought to the required width, after which nails or staples are driven through the openings b of the brackets b to rigidly connect this bar a, with the horizontal plain bars a' and a The portions of the bars a' and a projecting beyond the member cu as shown in Fig. 3, are cut off and made flush with the same. The cord d of the members a' and a which a have been slightly withdrawn from their respective grooves a as shown in Fig. 3, to permit of the shifting of the member a is now cut off close to the frame a, and the loose portion and the fabric c is reinserted A cord d is now placed over the fabric c, and both together are forced into the groove a of the member a and fastened in the'manner hereinbefore explained. The portion of the fabric c extending beyond the groove a of the member w* is removed, and the screen-hame a is now inserted into the window-frame e, with the flexible fabric c facing the window-sash e' thereof, as shown in Fig. 2. This arrangement permits of the raising of the window-sash e' without permitting insects to pass between the sash and screen a, since in this instance the lower portion of the window-sash by resting flush against the fiexible fabric c will form, in conjunction therewith, an insect-proof closure.

As it is only necessary to Shift the bar a* to adjust the rame a to the required width, the groove a of the bars a' and a opposite the bar a extends to the end of the bars a' and a as shown in Fig. 3. As shown in Fig. 8, the groove a at the other end of the bars a' and a has arectangular extension a which is in alinement with the groove a of the bar a and forms acontinuation of the same. The fiexible fabric c can be completely inserted in the grooves a and (1 at the left-hand-end of the frame a, whereas at the right-hand end the fabric c and cord d will rest in the absence of the groove extension a on the ungrooved portion a of the bars a' and a before reach'- ing the groove a of the bar a These portions of the fabric c and cord d being thus rendered accessible permit of an easy removal of the cord and fabric when the same is torn or is to be replaced by other fabric.

In order to hold the screen a in position' in the window-frame e by placing the same in front of the lower window-sash e', the frame is provided With guides f, preferably formed of a strip of metal having side fianges f &2,490

which by engaging the screen a in the manner shown in Figs. 1 and 2 connect the same -wth the window-frame e. A portion of the strip f is cut out and struck upward in the manner shown in Fig. 7 to form a leaf-spring f which when the screen a is raised in the windowrame e and brought into engagement therewith serves to hold the screen ain any given position therein.

Having thus described the nature and obj ects of my invention, what I claim as new,

and desire to secure by Letters Patent, is-

1. 'A window-screen, consisting of a series of plain bars-and a series of clamp-bars, the clamps of the series of said clamp-bars adapted to be rigidly connected with their respective bars and to form projecting eyes, at both ends of the same, said eyes adapted to receive and to surroundthe other series of plain bars y\ and to loosely connect the same with said .clamp-bars to permit of the sliding of said clamp-bars on said plain' bars to required position, means adapted to lock the clamps to said plain bars to form in conjunction with said clamp-bars a substantially rectangular and rigid frame, a fiexible fabric, grooves arranged in said plain and clamp bars adapted to receive said fiexible fabric and to hold the same taut thereon, and means engaging said grooves and the fabric and adapted to removably connect the same with said bars.

2. A window-screen, consisting of a series of plain bars and a seres of clamp-bars, the I IOO at the other end, said flexible fabric adapted to be inserted in the grooves of said bars and to rest upon the ungrooved portion of said plain bars to permit of a ready engagement and removal of the fabric from said grooves, and means engaging said grooves and the fabric and adapted to removably connect the same with said bars.

In testmony whereof I have hereunto set my signature in the presence of' two subscribing witnesses.
