Figure 4 is a section on line 4--4, Figure 1, and

Figure 5 is a fragmentary view in rear elevation partly in vertical section 'of a double window showing the adaptation therewith of the lower portion of a modified form of sash opening and :ilosing operator in accordance with this inven- With reference to Figures 1 to 4 of the drawings, I and 2 indicate the hollow sides ot a window frame 3 vbetween which is arranged a series ol superposed window sashes 4. The number of sashes 4 of the series may be as desired and by way of example but two sashes are shown. 'I'he sashes 4 are pivoted at their sides to the frame sides I, 2 as at 5. The top and the sill of frame 3 are indicated at 8, 1, respectively.

The sash opening and closing operator 8 is common to and functions to simultaneously open and close the sashes 4. The operator 8` will include superposed spaced sash opening and closing mechanisms 9 of like form corresponding in number to the number of sashes 4. Each of said mechanisms will include a pair of aligned spaced sections I0, II connected to a sash 4 and with the section Ill being spring controlled. The sections III and II are'connected tothe frame sides I, 2,

respectively.

The frame side I below the pivots i for a sash 4 is formed with an opening I2 having arranged therein and extended from the ends thereof a bushing or bearing I3. Mounted on the ends of the bushing or bearing I3 are inner and outer apertured spacer plates I4 iixedly secured to side I by the oppositely disposed holdfast means I5. The frame side 2 below the pivots 5 for a sash 4 is formed with an opening I6 whichaligns with the opening I2. Arranged in and having its ends extended from the opening I6 is a bushing or bearing I1. Mounted on the ends of the bushing I1 are inner and outer apertured spacer plates I8 iixedly secured to side 2.V by the oppositely disposed holdfast devices I9.

The section I0 is what may be termed a. sash holding means andl includes a rotatable stub shaft 20 mounted in and extending from each end of the bushing I3. Positioned on the reduced o'uter end of shaft 20 and bearing against the outer spacing plate I4. is the apertured inner terminal part of a lifting and lowering bar 2I for a sash 4. The said apertured inner terminal part ofthe bar 2I is secured on the outer end of shaftv 20 by the holdfast means 2 I. The bar 2l consists of inner and outer end parts 22, 23, respectively, and an intermediate part 24 arranged between, at an an? gle to and for disposing the parts 22, 23 in offset relation, that is to say, positioning said parts 22, 23 in parallel planes. The part 23 has its outer end arranged between andpivoted as at 25 to the outer ends of a pair of spaced parallel links 26. The inner ends of the links 26 are pivotally connected, as at 21 to a coupler 28 secured to the rear face oi one side stile of a sash 4. The inner pair of spaced parallel links 4I.

end'of shaft 201s formed with a head 29 bearing against the inner spacer plate I8 and provided with a crank arm 30 having a hook 3| at its outer end. Secured to the frame side I above the shaft 2D is an eye 32. Arranged between the hook 3| and eye 32 is a coiled controlling spring 33 having one end attached to the hook 3| and its other end to the eye 32. The springs 33 function as controlling means for the mechanisms 9 for counterbalancing the weight of the sashes 4 and also as a latching means for the mechanisms 9 for holding them when adjusted and such adjustment will be presently referred to.

The section II is what may be termed a sash shifting structure and includes a rotatable stub shaft 34 mounted in and extending from each end, of the bushing |1. Positioned on the reduced outer end of the shaft 34 and bearing against the outer spacing plate I8 is the apertured inner terminal portion of a lifting and lowering bar 35 for that sash 4 to which the bar 2| is coupled. 'I'he said apertured terminal part of bar 35 is secured on'the end of shaft 34 by the holdfast means 36. The bar 35 consists of inner and

outer end portions

31, 38, respectively and an intermediate portion 39 between, at an angle to and for disposing the

portions

31, 38 in offset relation, that is to say, positioning said

portions

31, 38 in parallel planes. The portion 38 has its outer end arranged between andpivotally connected, as at 49 to the outer ends of a The inner ends of the links 4| are pivotally connected, as at 42 to a coupler 43 secured to the rear face of the other side stile of the sash 4. The couplers on the side stiles of the sash 4 are arranged in spaced alignment, are of like form and each consists, with reference to Figure 1, of a plate 44 anchored by the holdfast means 45 (Figure 2) to the sash and formed with ashank 46 which extends between a pair of links and to which the inner ends of the latter are pivotally connected. The lifting arms 2|, 35 are oppositely disposed.

The section II includes the providing of the inner end of shaft 34 with a head 41 which bears against the inner spacing plate I8 and is formed with a crank arm 48 having secured to its outer end, as at 49 an actuating member 50 of linklike form pivotally connected, as at I to one of the couplers 52 of a plurality of superposed spaced couplers forming parts of a vertically movable carrier structure 53 which forms an element of the operator 8.

'I'he carrier structure 53 will include spaced superposed couplers 52 corresponding in number to the number of opening and closing mechanisms 9. The carrier structure 53 not only includes the couplers 52, but also a vertical tube 54 of a length less than the height of the window frame and which is arranged in the frame side 2. The upper portion of inner face of the tube 54 is formed with threads 55. Arranged within the tube 54 below the threads 55 is a bushing 56. The tube 54 is provided intermediate its ends and lengthwise thereof with an elongated slot 51. The bushing 56 is also formed with a slot 58 which registers with the slot 51. There is correlated with the tube 55 a stationary combined guide and arrester element 59 which functions to guide the tube 54 and also prevents the revolving of the tube on its vertical axis, as well as prevents the bushing 56 revolving relative to the tube 54. The element 59 is arranged in the frame side 2 and includes a base 68 which is fixedly secured by the holdfast means 6| to the inner face of the body of frame side 2. Formed integral with the base 68 is a shank 62 which merges into a collar 63 encompassing the tube 54. The collar 63 is of materially less length than the slots 51, 58 and has its inner face formed with a key 64 extended in to the said slots 51, 58 to arrest the turning of tube 54 on the vertical movement of the latter. The collar 83 constitutes a guide for tube 54. Each coupler 52 surrounds the tube 54, is secured to the latter by the holdfast means 65 and has a portion 66 extended towards the sash 4. The portion 66 has extending therethrough a headed pivot bolt 61 connected to said portions 66 by the nut 68. 'Ihe bolt 61 forms the pivot for the actuating member 50.

The operator 8 includes an operating mechanism 69 for the carrier structure 53. The mechanism 69 consists of a rotatable vertically disposed elongated shaft 10 which extends through and is of greater length than the tube 54. Arranged within the lower portion of frame side 2 is a stationary gear box 1|. Journalled in the gear boxI 1|, as well as extending rearwardly from frame side 2 is a rotatable shaft 12 having fixed thereto a bevel gear 13 disposed in the box 1|. The rear end of shaft 12 is provided with a crank handle 14 for the purpose of rotating the shaft 12. The shaft 10 extends into the box 1| and is provided on its lower end with a bevel gear 15 which permanently meshes with the gear 13.

Arranged on the top of box 1| and interposed between a collar 15 on shaft`10 and box 1| is a bearing means 16. The top 6 of frame side 2, within the latter has a depending inverted yokeshaped member 11 (only half of which is shown). The bight 18 of member 11 has secured to the lower face a bearing means 19 for correlation with a beveled bearing enlargement at the upper end of shaft 10. The latter in proximity to its upper end is formed with peripherial threads 8| for coaction with the threads 55 on the inner face of the tube 54 to provide for the elevating of the latter on the clockwise movement of shaft 10 to open the window sashes and for the lowering of the tube 54 on the anti-clockwise movement of the latter to close the window sashes. The opening movement of the window sashes is had against the action of the springs 33. When the tube 54 is moved upwardly, the couplers 52 of the carrier 53 will act on the sections |I of the mechanisms 9 to provide for such sections I| to lift open the window sashes and these in turn will actuate the sections I0 of the mechanisms 9 against the action of the springs 33. These latter, at the end of the desired extent of the upward movement of tube 54 will act to latch the threads 55, 8| whereby the Window sashes will be latched on their adjusted open position, and they also act to latch the window sashes closed.

With reference to the structure shown by Figure 5, it illustrates a modified form of sash operator, in accordance with this invention for adaptation with a window 82 having two parallel sets of

window sashes

83, 84. The window as shown consists of two like parallel sections 85 one for each set of sashes. Each section will consist of an outer and an inner side frame member. The inner side frame member indicated at 86 is common to both sections. The outer side frame members of the sections of the frame are not shown, but each will accord in structure to the side member heretofore referred to. In the modified form the sashes of one set will laterally align with the sashes of the other set to form pairs of aligned sashes. Each of the aligned sashes of a pair has correlated therewith a sash opening and closing mechanisms 8 of the form referred to. The sections i of the mechanisms 8 are not shown, but the sections Ii are and are indicated generally at 81, 88, Figure and each corresponds in all particulars with respect to their structural arrangement to section III of mechanism 8. 'Ihe

sections

81, 88 are of like form and correspond in construction to the section Il, but are oppositely disposed. The sashes, 84 will be arranged in the sections 86, pivotally supported from the outer side frame members and from the inner side frame member 88. The modified form shown by Figure 5 includes a carrier 88 of the same form as the carrier 88 with this exception, that the couplers 80 of the carrier 88 will have the

sections

81, 88 of the mechanisms 9 pivotally connected to opposite sides thereof as at 9i. The carrier 88 is arranged in the inner side frame member 88. The said

sections

81, 88 of the mechanisms 8 will be pivotally supported by opposed walls of the inner side frame member 86. The operating means 82 for the carrier 89 is arranged within andv extended from the inner side frame member 86. The means 82 corresponds in structure to the means 88. Otherwise than that as stated the modified form shown by Figure 5 and generally indicated at 83 will be of the same construction as the form sash operator shown by Figure 1. The form 88 is employed for simultaneously opening and closing a pair of laterally aligned spaced window sashes, or simultaneously opening and closing superposed pairs of laterally aligned spaced window sashes.

Although the sashes are shown as being shiftably supported from the pivots 5, yet it is to be understood that they may be hinged in lieu of being pivoted.
