CASElENT-WINDOW SCREEN OPERATING IECHNIBI.
application and september 1n, im. 'semi no. 731,639.
To all whom :it may concern.'
Be it known that I, AnoL'PH LUNDGREN, a citizen of the United States, and a resident of the cit of Chicago, county of Cook, and Stateof llinois, have invented certain new and useful Improvements in Casement-Window Screens with Operating Mechanism, of which the following is a specification.
. My invention relates to a new and useful easement window screen with operating mechanism, and the main object of the invention is to provide such a screen with means or mechanism for conveniently operatin the screen positioned at the inner side of t e easement window.
Other objects will appear hereinafter.
The invention consists in the combinations and arran ements of parts hereinafter described an claimed.
The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and 1n which,
Fig. 1 is an elevational view of my invention applied to a leasement window,
Fig. 2 is an enlarged vertical section taken on line 2-2 of Fig. 1, Fig. 3 is a cross section taken on the line 3-3 of Fig-2,
Fig. 4 is an enlarged vertical section taken on line 4-4 of Fig. 1,
Fig. 5 is an enlar ed horizontal section taken on line 5 5 of `ig. 1,
Fig. 6 is a vertical sectional view taken through the operating means, when the screen is unrolled,
Fig. 7 is a horizontal sectional view showing a modified form of operating means, and
Figs. 8 and 9 are vertical sectional views taken respectively on lines 8-8 and 9-9 of Fi 7. U 15' invention is especlally adapted for use with a easement window, and'in the drawings I have shown a window frame 10 with an outwardly opening Y pair of casement windows 11. The roller 12 with the screen 13 thereon is mounted within the upr part of the window frame, out of view, and slots 14v are rovided in the sides of .the frame for the s1de edges of the screen to travel |through. A sheave 15 with a guard flange 16 is fastened with screws or an suitabel means to each end of roller 12 an preferably has a friction ring 17 of leather or the like fastenedaround its exterior. A pin 18 extends through said sheave into the roller and is journalled in a bracket 19 whlch is secured into the window frame for rotatably mounting said roller.
The operating mechanism or means, in the preferred form illustrated in Figs. 1 to 6, comprises an o eratin member 20 secured to a shaft 21 an rotata ly mounted therewith 1n plates or side members 22 removably mounted 1n the posts 23 of a bracket 24 which is secured with screws or the like to the lower member or base plate 25 of the wmdow frame 10, as shown in Fi 6. A crank or member 26 is provided vor manually operating shaft 21 and member 20, and
'is connectedv to said shaft with a pivot pin 27: so as to be swung laterally against the window frame and underneath the front part of base plate 25 (see Fi 1 and 6) so as to be placed entirely out o the way.
The member 20 is constructed or provided wlth an annular flanged portion or sheave 28, preferably formed integral therewith, around 'whlch is looped an endless flexible member or cable 29 which extends in opposite .directions from the saidvmember and over uide pulleys 30 mounted'on shafts 31 lac within the lower corners of frame 10, neath base plate 25, and said cable passes up over the sheaves 15 on roller 12 and down again over pulleys 32 on said shafts 31, and.
extends beneath member 20. This endless cable actuated by said annular portion or sheave 28 provides means for en a 'ng the sheaves or means 15 on the ends 0% tb roller' and for sitively operating said roller to roll up t e screen. The member 20 is also provided with spirally grooved meansV 33 which is preferably in the form of a conical portion with a pair of spiral grooves on its exterior extending from said sheave 28 Ato the opposite lar er end of operating member 2 0; and a pa1r of flexible members or eables 34 are fastened each with one end 35 in openings at op site points of said larger end, and exten over pulleys 36 mounted on `said shafts 31 and are connected to the outameter as to properly compare with the diameter of sheaves 15 on roller 12 and with the varying diameter of the unrolling and the rollin screen, that said screen is rolled and unrol ed by means of said sheave 28 and conical portionk 35 so that said cables 29 and 34 will always be o rated lat an equal tension and without pr ucing any slack in' either one of them; this may be readily effected bymaking the sheave 28 equal in diameter with the sheave 15,and making the larger end of the spirally grooved portion 33 equal in diameter with the diameter of the screen when rolled upon the roller, and by making the smaller end of the spirall grooved portion 33 equal in diameter with t e roller 12 or the inner part of the screen when substantially entirely unrolled. This is apparentwhen it is noted that the lower end of cable 34 is attached to the outer end of the groove portion 33, as best seen in Fig. 5, while the other end of said cable 34 is attached to the outer end of screen 13 and is located at the upper end of the window frame when said screen is rolled up,`
and as the screen is then unrolled from its larger diameter while the cable 34 is pulled downward, the lower end of this cable is winding around the larger end of conical portion 33, and thus continues being wound toward the smaller end ofA said conical portion 33 in exact ratio with the decreasing diameter of the screen as it is being unwound, and each rotation of shaft 21 with portions 33 and 28 will thus produce the proper amount of travel and tension upon the cables 34 and 29 respectively for operating the screen. l
In the modified form shown in Figs. 7, 8, and 9, the same construction of bracket means 22, 23 and 24 may be used and mounted in the lower part of the window frame 10, and` also the same shaft 21 with crank 26, and the pulleys 30, 32 and36, and cables 29 and 34, may be used as in the preceding form; but in place of the above described single conical member 20 With two spiral grooves thereon, two conical members 40 are used each having a single spiral groove 41 on its exterior and a gear 42 at its smaller end, each member 40 beine' rotatably mounted with an axle 43 placed 1n additional openings provided in the plates 22, adjacent the openings in which shaft 21 is mounted; and a gear 44 with an integral member or sheave 45 is secured on shaft 2l and engages said gears 42 to operate them in unison in 'the same direction. The endless cable 29 is looped over said sheave 45 in the same manner as over sheave 28 in the preceding form, and the lower or free ends 35 of cables 34 are each fastened tothe larger end of one of the members 40, each being wound in the single spiral groove 41 during the unwindin of the screen 37, instead of both of said ca les 34 being wound in the double grooves 33 provided on member 20 in the preceding form. The result and operation of this formof mechanism is the same as in Vthe receding form.
e plates 22 are preferably arranged to be adjustable, as by use of screws 46 extending down through the window stool or plate 25 and engaging in threads 47 in said plates 22 to adjust and retain said plates vertically, the heads 48 of said screws being held in position between the material ofthe window plate or stool and a plate 49 seated in the top of said window plate or stool and fastened in position thereon with suitable screws or the like.
The above described mechanism in either of its forms, thusprovides means for posif tively rolling or unrolling the screen, and is conveniently operated by means of the crank 26 which is readily foldableagainst the window frame and out of the way, and no springs of any kind are used or needed for either .rolling or unrolling'the screen as is necessary in the usual construction.
WhileI have illustrated and described the preferred formof construction for carrying my invention into effect, this is capable of variation and modification Without departing'from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims:
