POWER FOR WINDOW-OPERATORS.

T 0 all-207mm it may concern.

Be it. known that I, JOHN J. PARKER,,a citizen of the United States, and residentof Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in. Power for for Window-Operators, of which the following is a specification. V

My invention relates to improvements 1n power devices for window sash operators such as are employed for operating a series of pivotally hung or hinged sash as commonly used in foundries, factories and the like.

The invention is particularl designed for what is commonly known as ouble or twoway sash operators, including two connecting arms and a pair of slidable rods to which the arms are attached, said rods being adapted for longitudinal movement in either direction but at all times in opposite directions one tothe other.

The purpose of the invention is to simplify and improve upon the construction of power devices of the above class and particularly to provide a novel and inclosed form of construction to which'the'said parallel longitudinal operating rods may be directly connected, and further to include a single shaft and wheel for operating the slidable rods simultaneously in opposite directions.

The power is further designed for close attachment to the part of the window casing or other support at any point along the line of sash to be operated and'likewise nearby and in alinement with the operating rods whether the same be near the floor 0r elevated therefrom, and to include means connected with the driving elements of the power whereby the same may be manuallyv operated by a suspended chain from the floor beneath, or like positions, or operated by a motor or other driving means.

With these and other objects in view the invention resides and consists in the construction and novel combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended, it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claim'mayfbe resorted to without departure from the spirit or sacrificing any of the advantages of the invention;

Similar characters of reference denote like Specification of Letters Patent.

or corresponding parts throughout the several figures of the accompanying drawings forming a part of this specification, and upon which, 7

Figure 1 shows a sectional plan view of a series of windows provided with double sash operators and my improved form of power for operating the same.

*ig. 2 is an enlarged sectional elevation of the power shown in Fig. 1 taken on line Fig,-3, and

ig. 3 is a vertical section of the same taken on line 33 of Fig. 2.

In Fig. 1 I have shown a commercial form of. double acting window sash operator as employed for some classes of large windows and to which my improved power device is shown connected. Referring in detail thereto, 5 represents the window frame, 6 the sash pivotally hung in the window frame, 7 represents brackets attached to the casings of the window frame, for supporting the two longitudinally arranged slid-.

able rods 8 and 9 forming the operating members to which the series of sash are con nected for operation. These slide rods are connected with the power apparatus whereby the rods are simultaneously slid in opposlte directions to adjust the operators and window sash.

Each sash is provided with two arms 10 and 11, one of which is pivotally connected to one edge of the sash and the other to the opposite edge of the same sash. The outer end of the first, mentioned link 10 is pivotally connected at 12, to the upper slide rod 8 and the lower link 11 is similarly connected to the lower slide rod 9. In practice the upper rod is moved longitudinally to the left while the lower rod is similarly moved to the right, thus having opposite movements which causes the opposite ends of the arms together with the sash to which they are pivotally connected to swing out to open the window, whereas the opposite sliding movements of the operating rods will obviously serve to close the sash.

The power is shown applied to the window mullion between two series of windows and to its opposite sides are the two slide rods employed for operating the two sets of window sash operators.

. In Figs. 2 and 3 this same form of power is shown upon a larger scale and as will be noted includes a housing 13 for support ing and inclosing the principal operating shaft 20.

of the brackets are provided with screw holes for attachment to the window mullion in the manner indicated in Fig. 3. By reason of the slots 18 provided in the arms 16 I am able to adjustably position mypower at any distance from the face of'the window casing to properly aline with the position of the operatlng shafts to which the power is connected.

' I provide a bearing'in the back 19 of the housing to support one end of the operating shaft 20 and also provide a similar bearing 21 in the central portion ofthe closure plate 14: to support the other end portion of the Upon the housed portion of this shaft is secured a spiral gear 22 and upon its outer end is mounted a sheath wheel 23, the said parts being secured in position by means of nuts 24 and 25. vided. to engage the annular groove of the said wheel 23 from which it is suspended and whereby itmay be operated by a per-' son standing on the floor.

Shafts 27 and 28 are alike in construction and each include a threaded portion 27 and 28 which are mounted to freely turn in the alined bearings 29 provided for them'in the opposite sides of the housing. I also provide upon the threaded portion of each of these shafts just inside of the bearings 29 a thrust bearing 30 which, as will be noted, is particularly positioned between said bearings and the spiral gears 31 and 32 contained within the housing and threadably mounted upon the threaded portion of each of the said threaded shafts 27 and 28. Said spiral ears 31 and 32 are positioned, one above the other, in mesh and in operative alinement with the above mentioned spiral gear 22 secured upon the operating shaft 20, ar-

ranged intermediate of the said shafts 27 A chain 26 is proand 28, so as to be operated thereby. The

tufiing of the operating shaft 20 therefore toether with its spiral gear 22 will obviouslyiserve to rotatethe' upper gear 31 in one direction and the lower shaft in the opposite direction,.thus-moving the upper operating rod lower one to the right.

As before stated the operating rods 8 and 9 are preferably formed of pipe which are slidably mounted in the several brackets? secured to the window casingorother support and are conveniently attached to the opposite ends of the shafts 27 and 28 and by simply being slid on the ends'as Shown in Fig. 2 and secured by means'of the pins 33.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is-" i V In combination with two-way window sash operators, a power device comprising a housing and means for adjustably attaching the same to a support, two longitudinally arranged threaded shafts journaled in the housing and adapted to move longitudinally and in opposite directions therein, a spiral gear mounted upon each of the said shafts and in threaded engagement therewith, an operating shaft 'journaled in the housing at a right angle to the above mentioned threaded shafts and intermediate thereof, a spiral gear mounted upon the said operating shaft and meshing with the two above mentioned spiral gears on the threaded shafts, an operating pulley mounted upon the outer end of the operating shaft, and means connected therewith for rotating the same together with its shaft, whereby the threaded shafts will be caused to move in opposite directions for the purpose described.
