' Appiication-fled May's, 1920. Serial No.' 5 ,,095 -i This inventionrelates to 'WlIlClOW openers andhas for. aniohject to provide a device adapted toopen a-window'such as a casement window and permit of the window being re- 1 i versed sothat the outside of the window pane may be washedffromr the inside ofthef room. A further object is toprovide "a casement Window opener'which willloperate'to autoe maticalLy lock-the window in full'opent' or closed positions asuwell aszin: anoblique open I position. i

A still: further" object is to provide a casement window opener which' will be operated from: insidethe window casing and-gw-hich will be formed of aejfew strong anddurable parts that will :be inexpensivetomanufacture and willn'ot easily get out .of order. A still furtherobject is to provide ;af-'- win-' dow openercin which the operatingx lever andi the; locking parts associated therewith" I will be positive 'in actioni to" open and close the windowandz' willbe carried: "by a novel housing which may be easily" and1q'uickly attached'to' the window easing without alterations thereto; i

With .theabove andother objects view the' invention consists in certain novel details: of constructiorr. and combinations of" parts hereinafterrfully described and claimed, it being understood that" various modifications may he resorted-"2130 within thescope} ofv the n appended claims o-without departing from the; spirit or-sacri'ficing any "ofi'the advantages {of the-invention; In the accomp part of this speoification',.

Referring now tothe drawings in v which like oha-racters of reference designate similar parts in the various v1ews, 10 des1gnates awindowi-casing', 11 the frame of 'a, casement window, the window'havingtheusual glass 7 pane 12, and 13 designates in general a window, screenwhich as usual incaseinent win-v 7 dow construction is mounted in the wi'ndow' casing inside the window. V V Y Incarrying out the preferredembodiment of the inventiorn-ilf preferably use hinges ofi' the general type described in my co-pending application filed ofeven'date herewith, said hinges each comprising. leaves 14 and 15- hingedly connected together as shown at 16;

Fhe leaf leis-rigidlysecured to the casement? window frame 11 and -'thehinge 14 is hinged as shown at 17' to a securing plate'18 ;whi"chis rigidly" secured to the window casing 10. The hinge-14 is provided with-a locking lug 19 which" is engaged by a locking latchfQO, best shownin Figure 9 as pivoted on a flange 21;.earried by the leaf 15. The latch is proface of the flange andprojects into a thumb notch23. 7

The leaves 14. and. 15 normally'flie flat against each other to permit of the window being opened inthensualmanner to the positionshown in dotted 'lines in 'Figure' 1 However, the leaves are adapted to open as best shown in FigureQ when it is desired to? reverse the-window for washing the inside Figure 6 is a fragmentary plane View ShOW1-.

9O vided with agrip 22 which liesflush with the 9 of the window pane or for permitting the I windowto remain open in an oblique position I to provide better ventilation.

The operating mechanism for opening and closing the window comprises in general a lever arm 24 which is terminally slotted as shown at 25 toreceive the pivot pin 26 ofa *connecting link 27. The connecting link is terminally equipped with an eye 28 which is. pivoted to the connecting link as shown at 29 and encircles a guide rod30, the ends of which are fixedly secured preferably by screws 31 to t e lower horizontal rail of the casement window sash. V

When the pivot pin 26 of the connecting link is disposed at the inner end of the slot 25 in the lever armthe link extends-in align? ment with the lever arm as best shown 111 Figure 1 and' is-detachably secured lnithis positionby means of a catch 32 which is piv oted on the lever arm as shown at 33, and is terminally equipped with a lip' 34 as best shown in Figure 6, which lip engagesinregis tering slots formed in the lever arm and connecting link.

The lever arm 24 1S operated by means of an operating lever 35 which is operatively connected to the lever arm as will'hereinafter be fully described. lVhen the operating lever 35 is rocked transversely ofvthe window sill the lever arm 24 and'connec'ting link 27 will be rocked to the position shown in dotted lines'in Figure 1, thereby sliding the eye 28 longitudinally of the guide rod and swingingthe window to full open position. Should it be desired to reverse the window to the position shown in Figure2 it is'necessaryto disengage the catch 32 and move the connecting link 27 outwardly so that the pivot pin 26' thereoffis disposed at the outerend of the slot 25. r

The above described locking latches 20 of both the upper and lower hinges are first releasedto permit of the leaves of the hinges opening. The connecting link is now shoved outwardly on'the lever arm until the pivot pm 26 thereof engages in'the outer end ofthe slot Thereupon the operating lever 35 maybe rocked 1n thereverse direction from that used to open the window, and during this movement best shown in Figure 2,

'whi'oh is rigidly secured to abase plate 37 the latter being'preferablv secured to the window sill by screws 38. A fork 39 as best shown in 41 of the rack 36.

Figures 3, 4 and 5 isterminally equipped with teeth 40 adapted to engage between the teeth The fork 39 is pivoted on the base plate by a pivot pin 42 and is pressed. downwardly by a helical spring 43 which surrounds the pivot pin and is confinedqbetween the, fork and a cap or cover plate 44 which is of the general shape shown in Figure 1 and houses the fork and is mounted on the pivot pin 42 to turn thereon as aiiiiit with the fork. The fork is provided at its rear end with lips 45 to receive the end of the above mentioned oper- 'ating lever 35. When the operating lever 35 is depressed obviously the lever will serve to tilt the forkon the pivot pin 42 and disengage the teeth 40 thereof from between the'arcuate rackteeth 41 on the-base plate 27 as best shown in Figure 5. The lever 35 isnow free to be rocked to open or close the window and upon thelever being released. thespring 43' automatically depresses the fork 39 and engages the teeth thereof between adjoining teeth of the arcuate rack whereby are locked againstmovement.

the parts The operating lever 35 1s PIOVIdGClWl ClI a I longitudinal slot 46 which receives} a-pin47 whereby the lever may he slid: forwardly underneath the lips 45 of the fork to connect these parts or may be slid rearwardly so that the end of the lever is disengaged from the leaves of the fork whereupon the lever' may be rocked laterallyto normally extend longitudinally of the window sill'as best shown in Figure 1. By referring to Figure 3 it will be seen that the operating lever arm 2'? is secured by screws 48 in a socket member 49which is secured as shown in Figures 4 and 5 to the cover plate 44' by means of a screw: 50. The socket member is formed integral with a'plate 51 which is "provided with an opening 'to pivotally receive the pivot pin 42 above described and extends'underneath the above described fork 39 to the outer 'end of the cover plate where it issec-uredto the latter by means of the pin 47 above described and moves as a unit with the cover'plate 7 It will thus be obvious that the cover plate 44,socket member 49, plate 51 integral therewith, and the fork 39 are: all moved asa unit on the pivot 42 when --the-=lever- :35 is shiftedlaterally. It will. also be obvious thatthe fork 39 has verticalmovement against the pressure of the spring 43 whenithe lever 35 is depressedto idisengagethelocking teeth of the fork. The spring'depresses said fork to.-

engage said teeth when the lever is released.

It will be observed from the above desc'ripti on that the easement window opening mech anism will operate to automatically lock the window in full open,in closed, or in oblique intermediate open positions, or in reversed position. j y i 1 It will be further observed that thelocleing mechanismjis operated frominside the 7 window and is positive in action and that furthermore, the parts for the most part are housed within the casing constituted by the base plate 37 and cover plate 44' which parts may be easily and quickly attached to the window sill without alterations thereof.

It will be pointed outthat my improved device as above described is equally applicable to steel casement windows as well as wood.
