4 Claims.

This invention relates to a novel construction of window screen for windows having sliding sashes, and more particularly to a Window screen which, when not in use, will be contained in a recess of the window frame so as to be protected from the elements and not to obstruct the window opening.

More particularly, it is an aim of the invention to provide clamping means associated with the outer edges of the top and bottom rails of the sliding sash and which are connected to means manually operable from one side of said sash for opening and closing said clamping members so that said clamping members may be engaged with or disengaged from the free ends of strips of mesh wire fabric which are wound on spring rollers and which extend into the top and bottom of the window opening and in positions to be received by the open clamping members when the sash is at the extremities of its movement.

Still a further aim of the invention is to provide a construction whereby the side edges of the strips of mesh wire fabric will extend into slots in the stiles or perpendicular guides of the sash, when said strips are extended, so that the strips will completely close the parts of the window opening in which they are disposed, when in extended positions.

Still another aim of the invention is to prov! vide means for latching the clamping members in either open or closed positions so that, when in open positions, the sash can be moved in either direction to the extremity 01 its movement without the free ends of either strip of mesh wire 3:."

fabric being engaged by either of the clamping members. Other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawings, which illustrate a preferred embodiment thereof, and wherein- Figure 1 is a side elevational view looking toward the inner side of the window and with portions of the window frame shown broken away and in section,

Figure 2 is a top plan view of the same with the top panel of the window frame removed,

Figure 3 is a transverse Vertical sectional view taken substantially along the plane of the line 3-3 of Figure 1,

Figure 4 is a horizontal sectional view of the same taken substantially along the plane of the line 44 of Figure 1,

Figure 5 is a bottom plan view taken substan- Ill indicated by the line 5-5 ure 8.

Referring more particularly to the drawings, wherein like reference characters designate like or corresponding parts throughout the difierent views, In designates enerally a conventional construction of window including a frame, designated generallyjll and having a head I2, sill l3 and stiles I4 which combine to form the window opening 15 in which is slidably mounted a lower sash l6 and an upper sash IT, in a conventional manner. The upper, outer sash I 'l is of conventional construction and is supported in a conventional manner in a raised position by means of sash weights l8 through the medium of sash cords I9 which are attached to the weights l8 and the sash I1 and which are trained over rollers 20. The parts l8, I 9 and 20 are disposed in the recesses of the stiles M with the correponding upper ends of the sash cords l9 extending into the window opening I 5. The head 12 and sill l3 are recessed to form chambers 2| and 22, respectively, and the remote ends of the head 12 and sill l3 are provided with removable panels 23 to afford access to the chambers2l and 22. The inner sides of the head and sill are provided with elongated slot- like openings 24 and 25, respectively, which open into the upper and lower ends, respectively, of the window opening l5 and which are substantially wider than the window opening.

' Each of the chambers 2i and 22 contains a pair of roller supporting brackets including a bracket 26 and bracket 21. Each of the pairs of brackets 25 and 21 is adapted to support a conventional spring roller 28, in a conventional manner and so that when the roller is turned in one direction its spring will be tensioned to cause it to rewind. A strip or sheet of mesh wire fabric 29 is wound on each of the rollers 28. The strips 29 are provided with free ends which project through the slots 24 and 25 and into the upper and lower ends, respectively, of the window opening [5.

The side panels 33 which form. the inner sides of the stiles 54 are provided with corresponding longitudinally extending slots 39' in the ends thereof and in the portion thereof which is slidably engaged by the lower, inner sash 16. The slots 33 communicate at their remote ends with the ends of the slot- like openings 24 and 25 and terminate in spaced apart relationship to one another at their adjacent ends, as seen in Figure 3. The free ends of the mesh wire fabric strips 29 extend through the slot- like openings 24 and 25 and into the upper and lower ends of the frame opening l5 and the sides or longitudinal edges of the strips 29 extend into the slots 33', as seen in Figure 1, due to the fact that the strips 29 are substantially wider than the opening l5. The free end of the upper strip 29 is wrapped around and fastened to a rod 3| and the free end of the lower strip 29 is similarly attached to a rod 32 which rods are longer than the openings 24 and 25 so that their ends extend beyond the ends thereof to prevent said rods from being drawn through the openings 24 and 25 and into the chambers 2| and 22, respectively. The strips 29 are wrapped on the rollers 28 so that the spring tension of the rollers tends to wind the strips 29 thereon and to draw the free end thereof inwardly of the chambers 21 and 22 so that the ends of the rods 3! and 32 form stops for limiting this movement of the strips 29.

The rollers 28 are preferably not provided with latch means so that they are constantly spring urged to wind the strips 29 thereon.

Referring particularly to Figures '1 to 10, the lower, inner sash it includes a bottom rail 33 and a top rail 34 which rail are provided with channels 35 in their outer longitudinal edges so that the bottom rail 33 is provided with a downwardly opening channel 35 and the top rail 34 has an upwardly opening channel 35. The channels 35 extend the length of the rails 33 and 34.

A clamping member 36 is disposed in and extends substantially the length of the channel 35 of rail 33 and a similar clamping member 31 is disposed in a like manner in the channel 35 of the rail 34. Clamping members 39 and 3'! each comprise sections 38 and 39 which are substantially semi-circular in cross section so that the clamping members when closed, as seen in Figures '7, 9 and are substantially tubular in shape. The sections 38, of the clamping members, are fixedly secured in the channels 35 by fastenings 40 which engage the rails 33 and 34.

Referring to Figure 8, the bottom rail 33 is provided with a centrally disposed recess 4| containing a lining 42 of suitable material such as metal. Recess 4! opens outwardly of the inner side of the rail 33 and is adapted to be normally closed by means of a door 43 which is hinged at one end thereof to the inner side of the rail As shown in Figure 8, the rail 33 at each end thereof is provided with a recess 44 and a recess 45. Recesses 45 are disposed above the complementary recesses 44. The ends of the lining 42 are provided with openings 46 which communicate with the recesses 44 and openings 41 which communicate with the recesse 45. A shaft 43 extends through the recess 4i and is loosely disposed near its ends in the openings 43 and has its ends extending into the recesses 44. A shaft 49, similar to the shaft 43 i disposed thereabove and loosely disposed in the openings 41 and has its ends extending into the recesses 45.

The perpendicular side rails of the sash l3, designated 39, and the ends of the rails 33 and 34 are recessed, as seen in Figures 7 and 8. Said recesses include elongated recesses {it which extend into the ends of the rail 33 and shorter recesses 52 which extend into the ends of the rail 34. The recesses 44 and 45 open into the recesses 5! at their remote ends and said remote ends are normally closed by means of plates 53 which are disposed in the recesses 51 and fastened therein by means of fastenings 94. The shafts 43 and 49 are provided with stub shafts 55 which project from the ends thereof and which are eccentrically disposed relatively to the shafts 48 and 49 and which are journaled at their free ends in openings 56 in the plates The shafts 43 and 49 are also provided with shorter stub shafts 51 which project from the ends of the shaft 4S and 49 and which are substantially smaller in diameter than the stub shafts 55.

The plates 53, at their outer ends, are provided with notches or recesses 58, as seenin Figure '7, in which are disposed the ends of the lower clamping member 36. The ends of the section 33 of the lower clamping member 35 are provided with transverse. slot like openings 59 to loosely receive projections 39, forming a part of the plates 53 and which are hook-shaped and extend into the notches or recesses 53 to loosely engage in the openings 59 of the section 39, as shown in Figures '7 and 8. The inner longitudinal edge 55 of the section 39 of the lower clamping memher 36 is provided with a plurality of ears 32 Which project therefrom upwardly into the re cesses 44. As seen in Figure 8, an ear 62 projects from the edge 6| of the lower section 39 adjacent each end thereof. The complementary longitudinal edge of the lower fixed clamping section 33 is provided with recesses to ac commodate the cars 32. A link 34 is pivctally connected to a stub shaft 51 at each end of the shaft 48. The links 64 are pivotally connected to the stub shafts 57 at their upper ends and are pivotally connected, as seen at 65 at their opposite, lower ends to the free ends of the ears 62. A plate 69 is disposed over the lower end of each of the plates 53 and is a'tached thereto by one of the fastenings 54. The plates 33 are recessed at their lower ends as seen at it! to fit round the ends of the lower clamping member 36. Plates G3 are provided with extensions which project into their recessed portions 3'? and which are provided with arcuately shaped heads 38 which are disposed in the ends of the lower clamping member 36 to form a guide for said ends. Extensions 58 have restricted shanks 69 which extend through recessed portions l9 in the ends of the lower clamping section The upper clamping member 3? is of identi cal construction with the lower clamping rnero ber 36. The recesses 52 contain inner plates 1!, corresponding to the plates and outer plates 12 corresponding to the plates 63 which piates are attached to one another and secured in the recesses 52 by fastenings 73. The plates H are provided with notches 58 and hook shaped portions 50 for the same purpose as the similarly designated parts of the plates 53 and the plates 12 are provided with recessed portions 3'! and extensions 53, for the same purpose as the similarly designated portions of the plates 35.

Perpendicular bores 14 extend through the rail 34, the rails 59 and portions of the rail 33. The upper ends of the bores 14 open into the upper channel 35, adjacent the ends thereof,

and the lower ends of the bore 14 open into the recesses 45. A link extends loosely through each of the bores M. Links 15 are pivotally connected at their lower ends to the stub shafts 57 of the shaft 49 and are pivotally connected at their upper ends at 65 to the free ends of the ears 52 of the upper movable clamping member 39 in the same manner that the links 54 are connected to the ears B2 of the lower clamping section 39. As seen in Figure 8, ears 52 of the upper clamping section 39 extend into the upper ends of the bore 74.

Referring to Figures 3 and 8, the shafts 48 and 4.9, intermediate of their ends, are provided with transverse openings 16 through which loosely extend the restricted shanks of headed pin T! which pins serve as handles and are disposed in the recess 4| with their headed ends projecting toward the open side thereof. The rail 33 is provided with recesses 18 which extend through the lining t2 and which open into the recess 45. The recesses 13 are disposed in alinement with the openings 16 when said openings are in a horizontal position, as seen in Figure 3.

When thus disposed, the pins may be projected inwardly of the shafts st and 49 so that their shank ends will engage in the recesses l8 to form latches therewith to prevent the shafts 4S and ts from turning to thereby retain the clamping members 38 in closed positions. Similar recesses 19 are formed at the top and bottom of the recess 4! for receiving the shank ends of the pins 77 when the openings 15 are inclined inwardly and upwardly of the recess 4| for latching the shafts 43 and 4-9 in positions, not

shown, for holding the clamping members 3% in open positions, not shown.

Assuming that the sashes l6 and El are mounted for sliding movement vertically the frame i i, it will be readily apparent that the upper sash I"! will operate in a conventional manner and will be maintained in any position to which it is moved by the sash weights E8. The inner, lower sash it is not provided with sash weights for supporting it in a raised position. However, the spring of the upper roller 28 is intended to be sufiiciently strong to maintain the inner lower sash it in a raised position when the upper strip of screen fabric 29 is attached thereto, as seen in Figure 3.

The operation of the clamping members and 3'! is the same and the description hereinafter given of the operation of the lower clamping member 38 will therefore serve as a descripton of the operation of the upper clamping member 3?. As seen in Figure 9, the lower clamping member is shown in a closed position with the outer edges 89 and SI in close proximity and with the shaft portions and 51 disposed in substantially horizontal planes relatively to one another. In order to open the lower clamping member 35, the pin it of the shaft 48 is retracted outwardly, after having opened the door 43 to thereby release the shank end of the pin T! from its recess 13. Pin TI is then swung upwardly to turn the shaft .8 in a counterclockwise direction, as seen in Figure 9, to cause the link 54 to be moved downwardly to thereby force the ears 62 downwardly. As the lower clamping section 39 will be prevented from moving outwardly of the lower channel 35 by engagement of the hooks M with the slots or openings 58, it will be readily apparent that the upper portions of the slots 59 and the hooks 66 will form pivots on which said section 39 will swing so that the ears 62 can swing downwardly and partially into the recesses 63 thus causing the lower longitudinal edge 8! to swing in a direction away from the complementary edge as to open the lower clamping member suiiiciently so that the rod 32 can pass readily therein/to. When the shaft 58 is thus turned in a clockwise direction to the limit of its movement as permitted by the links 64 and connected ears 62, its pin 16 can be projected inwardly to engage the lower recess 19 for thereby latching the lower clamping member 35 in an open position so hat it will not engage the rod 32. The upper clamping member 37 can be opened in a like manner by retracting the pin it of the shaft id and swinging said pin downwardly for turning the shaft 49 in a clockwise direction, as seen in Figure 9, and said pin can also be projected to engage the upper recess T9- for latching the clamping member 31 in an open position.

In order to move the sash It to a fully lowered position, when the clamping member as is not in engagement with the rod 32, it is essential that said clamping member be open since when the sash is in its fully lowered position the rod 32 must be disposed in the clamping member 35 al though not necessarily engaged thereby. Likewise, the upper clamping member 3? must be in. an open position in order to move the sash 16 to a fully raised position when the upper rod 3! is not engaged by the clamping member 37.

It will thus be readily apparent that by latcln ing the clamping members 35 and 3! in open positions, as previously described, the sash iii can be moved to a fully raised or a fully lowered position Without interference by the strips 29 or their rods 3! and 32 and by moving the clamping member 36 to a closed position, while the sash is in a lowered position, the rod 32 and the free end of the lower strip 29 will be engaged by the lower end of the sash to be drawn upwardly when the sash I6 is raised. The clamping member 31 can be similarly connected to the rod 3! of the upper strip 29 by moving the sash to a fully F raised position and then actuating the operating shaft 49 for closing the clamping member 3?.

When the two strips 29 are connected to the ends of the sash IE, it will be readily apparent that when said sash is moved downwardly the upper strip 29 will close the window Opening thereabove and when the sash i6 is moved upwardly the lower strip 29 will close the window opening l5 therebeneath so that the upper sash I! need not be equipped with a window screen.

As previously mentioned, the slot- like openings 24 and 25 communicate with the slots 35' to accommodate the longitudinal edges of the screen strips, 29 so that they will completely close the portions of the window opening !5 in which they are disposed. As previously mentioned, the spring of the upper roller 28 is intended to be sufiiciently strong so that it will support the sash IS in a raised position even when the lower screen 29 is attached to the clamping member 36.

Various modifications and changes are contemplated and may obviously be resorted to, provided they fall within the spirit and scope of the invention as hereinafter defined by the appended claims, as only a preferred embodiment of the invention has been disclosed.
