WINDOW-OPERATING. DEVICE.

Specification of Letters Patent Application filed June 1,1916. Serial No. 101,073.

To all whom it may concern:

Be it known that I, CLARKE P. POND, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Window-Operating Devices, of which the following is a specification.

One object of -my invention is to provide comparatively simple and substantial mechanism for swinging one or a series of pivoted sashes 0r ventilators on their sup ports to open or close them, the arrangement.

of the parts being such as will allow of the accurate and inexpensive construction and erection of such mechanism as well as its convenient operation.

The invention also contemplates a novel arrangement of supporting structure, levers,

and connections, assembled to form mecha-.

Figs. 4 and 5 are respectively a plan and' a front elevation illustrating the detail construction of my operating mechanism;

Figs. 6 and 7 are-respectively a plan and an elevation of a slightly modified form of the invention;

Fig. 8 is a perspective view of one of the levers forming part of the device shown in Figs. 6 and 7 I Fig. 9 is an elevation, partly in section, of the lever-connecting link employed in that -lt'orm of my invention shown in Figs. 4 and 5; and

Figs. 10 and 11 are horizontal sections on the line 10-10 and 1111, respectively, Fig. 9. p

In the abov drawings 1 and 2 represent two sets of sashes mounted one above the other and supported to swing on; pivots 3 of which those belonging to any one set of sashes are placedat the centers of the sides or ends thereof. 4

Each set of sashes, as shown in Fig. 3, has projecting from it, adjacent its pivot, a plate or casting 4 constituting an operating arm and the arm at each side of the sash 1 is connected to the corresponding arm of the sash 2 below it by-a bar 5 so that the two sashes natu "ally swing together.

For opening and closing the sashes I provide a lever mechanism preferably mounted on a supporting framefi having approximately the form of two members extending at right-angles to each other and conveniently attached to the window frame between and to one side of the two sashes by screws or any other suitable means, so that its members he in a plane parallel to that of the sash frame. r

The vertically extending memberof sait frame 6 has pivoted to its upper end a lever consisting of two arms 7 and 8 parallel to each other and mad in a U-shaped form; the pivot being horizontal. The latter of these arms is pivotally connected tothe ad- Patented May 29, 191?.

jacent operating bar 5 of the sash while the outer extremity of the second member of the frame 6' so that it is free to swing in a substantially vertical plane.

As shown in Fig. '1, there is a pair of levers and their connecting link carried on a frame, 6 at each side of the sashes 1 and 2, and for actuating this mechanism I provide suitable means such as that shown in my Patent No. 886,851, datedMay 5th, 1908.

In the present instance I have illustrated two horizontally extending parallel rods or bars 13 and 1a which may be moved in opposite directions and to one of these is pivotallyconnected the second arm. 12 of the second lever which swings in a horizontal plane adjacent the left-hand one of the bars 5. Similarly an a'r1n12 ofthe horizontal lever'at the right hand end of thesashes is tween the arms -7 and '11 and the link 1.0 are 10 are made forked and the branches of each fork are connected by a suitable pivot pin 15 which has fixed to its central portion a spherical bearing structure 16. In the present case the adjacent extremity 17 of the lever arm is turned at right-angles to the body thereof and is perforated to receive this ball-bearing.

Similarly the pivot 18 at the opposite end of the link 10 carries a ball bearing 19 fitted into a perforation in the arm 7 of the vertically moving lever. With this arrangement of parts there is no binding'between the link and the two levers when these are moved in any of their possible positions and it is noted that the turned-up end 17 of the lever 11-12 extends in a' plane inclined to the center-line of the arm 11 as shown in Fig. 10.

Under operating conditions the simulta neous movement of the rods 13 and 14L in opposite directions causes a simultaneous swinging of the levers 11-12 on their pivots and if the sash be closed, the levers 78 are both swung downwardly on their pivots by power transmitted from the levers 11-12 through the links 10. As a consequence there is a downward force exerted on the projecting operating arms 4 of both sets of sashes and these latter are caused to swing on their pivots from their closed to their open position.

With this arrangement of parts the greatest leverage or opening force occurs when the sashes are closed or in contact withthe window frames, the movement being relatively slow but powerful and decreasing in force asthe sashes are opened. In some cases, however, I may construct the operating mechanism as shown in Figs. 6, 7 and 8. in which case the angle frame 6 has pivoted to the extremity of one of its arms a h0ri zontally swinging lever 1112 The arm 11 of this lever is connected through a link 10 with one arm 7 of the vertically swinging lever whose second arm extends preferably at an acute angle to said first arm. As before, the link is connected to two levers through ball joints and it is noted that as the lever 78 is moved from the position shown in full lines to that shown in dot, the pull or force exerted upon its arm 8" increases. This particular form of the invention is designed for the operation of sashes which are pivoted or hinged to their supports adjacent their upper ends so that it meets the increase of load resulting from the opening of the sashes, with an increase of leverage.

I claim 1. The combination in a sash operating device of a supporting frame consisting of two members substantially at right-angles to each other; a lever mounted on one mem ber of the frame and movable on a horizontal axis; and a second lever mounted on the other frame member and free to swing on a vertical axis; with means for operatively connecting said levers.

2. The combination in a sash operating device of a supporting frame consisting of .two bars extending substantially at rightangles to each other; a lever pivoted to one member adjacent the free end thereof and movable on a horizontal axis; a second lever pivoted adjacent the free end of the other frame member and movable on a vertical axis; with means for operatively connecting said levers.

3. The combination of a pivoted sash; a lever having an arm connected thereto and free to move on an axis parallel to the sash pivot; a second lever pivoted to move on an axis at right angles to that of the first lever and having an arm connected to a second arm of the first lever; with an operating member movable in either of two directions and connected to the second arm of the second lever.

1. The combination of a plurality of sashes; a bar connecting said sashes; a lever pivoted to swing on a horizontal axis and having an arm connected to said bar; a second lever pivoted to swing on a vertical axis; a link connecting the second arm of the first lever with one arm of the second lever; a power actuated member movable in a horizontal line; and means for connecting said member with the second arm of the second lever.

5. The combination of sash frame; a sash pivoted therein; a frame including two members at right-angles to each other and mounted on the sash frame adjacent two sides of the sash; a lever mounted on said one of said members and free to swing on a horizontal axis; means for connecting one arm of said lever to the sash; a second lever pivoted to the second member of the frame and free to swing on a vertical axis; a link connecting the second arm of the first lever with an arm of the second lever; a power actuated operating lever mounted to move adjacent the sash; and means for connecting said member with the second arm of the second lever.
