-comp anying drawings, is a specification.

' This invention relates to an improvement in screens and more particularly in screens of the type to be applied to a window of the pivoted sash type.

These windows are commonly used asa part of factory sash which has a centrally pivoted ventilator or sash so that when opened the lower half swings outwardly and the upper half swings inwardly leaving openings of varying sizes.

he usual way of screening such windows is to provide fixed screens secured to the inner face of the lower openings and to the outer face of upper openings, the latter screens being provided with projecting plates or flanges which bear against the pane of the upper half and close the spaces therebetween under all conditions. It is,

however, obvious that in screens of this type it is necessary to change the construction depending upon the particular position of the pivoting member with reference to the sash. V

The chief object of this invention is to provide a screen which can be applied to any type of pivot sashand in which the upper screen member is mounted upon-a fixed pivot, in contradistinction to the screen disclosed in the patent to Reese No. 1,343,933, upon-which construction this invention is an improvement. In the con struction shown in the Reese patent, the upper screen slides vertically and it is accordingly necessary that provision be made at the topof the window to pe mit such sliding movement. Hence, it is impossible to use the Reese screen in the form shown in the patent when the window opening is at the top of the sash, directly below the coping. v

Other objects reside in the details of construction hereinafter set forth as will appear from an examination of the following description taken in connection with the drawing which forms a part thereof and in which-- V Figure 1 is a front'elevation of the upper portion of a closed pivoted vsash win dow equipped with a'screen embodying one formof this invention.

, Fig.2 is, a cross section through such window showing the window open.

Fig. 3 is a sectionalview similar to Fig.

[2 of the central portion of the window when.

the sash is closed.

Fig. 4 1s a sectional view taken the line ,Hof Fig. 1.

Fig. .5 is a view of the pivot plate by through which-the upper screen is connected to the horizontal muntin of the window.

Fig. 6 is a view ofa "portion of that plate taken from the front/in the direction indicated by the arrow 6 in Fig. 3. I

Fig. 7 is-an elevation of one type of pivot pin which may be employed; Fig. 8 is an enlarged section of the upper end of the upper screenshowing the means whereby the screen is secured to the sash. Fig- 9 is a sectional plan view taken through the section line99 of Fig. 8.

10 is a plan view and c Fig. 11 a side elevationof the clamping means by which the pivot plate is secured to the muntin; and V Fig. 12 is a plan view of a portion of this clamping device in extended position.

Referring to the drawings the reference "numeral 20 is used to indicate a sash having a ventilator opening 21 therein in which a window 22 is horizontally pivoted at the and lower panes of glass 26, 27 separated by a muntin 28. The particular formation of the cross pieces 24' and 25, and the muntin 28 with referenceto the panes 26, 27 formino particular part of this invention but are shown for the purpose of illustration as comprising overhanging flanges 29 against the rear face of which the panes are securedby means of suitable putty 'or cement 30. At the top of window is provided a flange plate 31 which engages with the flange piece24 when the window is closed to seal the opening. A similar plate 32 is provided at the bottom .of, the opening for co-action with the flange piece 25 on the window;

Obviously, when the window is open as shown in Fig. 2, the spaces 33, 34c'permit of the entrance of insects and it is the purpose of this invention to provide means for mounting screens which will close the openings. By reason of the construction and screws or other fastening .means36 to the edges of the opening. The screen 35 termounting of the window 22 no particular difiiculty will be present in closing the opening 33 and it has been found desirable to employ a fixed screen 35 which is held by minates at the center of the pivot 23 and an angular plate 37 carried by the window closes the space between the screen 35 and the window at all times, the angle 38 of the plate 37 being at the center of the pivot 23 and hence bearing against the upper edge 39 of the screen in any position of the window.

The upper opening 34 is closed by'a screen 40 which comprises a screen frame 41 pivoted to side plates 42 secured to the strips 43 at either side of the opening 34. The screen 40 is pivoted near its upper end upon spring-pressedpins 44 which enter openings 44 in the side plates 42. The pin 44 is mounted in brackets45 secured to the sides of the screen in the upper cross groove 46. Arms 47, pivoted in the upper frame of the screen, engage the pins 44 and retract them against the urge of the springs 48 when it is desired to remove the screen. .The arms 47 project through the frame behind the screening 49 so that the screen can be readily removed from within. By thus mounting the screen any sliding movement vertically of the opening is prevented so that the screen may be mounted in any opening even though it be at the top of the sash directly below a coping 50. V

The plates 42 are mounted very near the sides of the screen 40 so as to close the space and prevent the entry of'insects. Pivoted to the lower edge of the screen40 is ,a plate ,51, which is also pivotally secured to the muntin 28 of the window. Consequently,

as the window is opened and closed the plate 51 pivots on and Swings relatively to the muntin, thetwo extreme positions being shown in Figs. 2and 3.

Both side edges of the plate 51? have flanged beads 52 cut away at intervals. In

order to secure'theplate51 to the screen straps53 are fixed in the horizontal groove 54 and have beads 55 which'corresponds in size to the adjacent bead 52 and which'are mounted at intervals so that the beads 52, 55 will interlock. The plate 51 is hinged to the straps 53 by means'of a suitable pin 58 introduced through the bead'portions 52 and 55.

Secured to the muntin 28 are a series of angled clamps 56, shown in detail in Figs. 10 and 11. These clamps have at one end a tip 57 preferably made independent of the main portion of the clamp 56 and shown in extended form in Fig. '12. Through the other leg 59 of clamp projects a screw 60. The clamp 56 is applied by inserting-the tip ,57, which projects at'an acute angle to the clamp, into the putty 30 between the flange 29 of the muntin 28' and the lower pane 27.

When the tip is so located the leg 59 will cross the center of the muntin so that by tightening the screw 60 the clamp will be "rigidly fixed 'in' place. The clamp is so formed that" the angle 61 which is semicylindrical in form will be above the face of the muntin.

secured to the'cla'mps 56 by means of hinge pins 63 passed through th'e'bead 52 and angles 61. The pins terminate in handles 64 which lie in the spaces 65 "provided'in the beads 52. The screws 60'a're suitably arranged so they can be reached from the'inside of the windowso that it is possibletd install orremove the screen 40 by working entirely from the inside.

The side plates 42 are fixed to. the strips 43 by clamps 66 similar in formation to the clamps 56 described above. However, in addition to the .tips 57 and screws 60 these clamps are provided with projections '67 which, when the clamp is mounted, as shown in Fig. 4, are parallel to'the line of the window. Secured to the side plates 42 are right angle brackets 68 fastened by screws 69 to the projections 67.

While one embodiment of this invention has been shown and described, I am not'to.

be limited thereto'since it is obvious that others may be made withoutdeparting from .the spirit and scope of the invention as set forth in the following claims.
