WINDOW-OPERATING DEVICE.

Specification of Letters Patent.

Application filed Isebruary 9, 1914. Serial No. 817,442.

To all whom it may concern:

Be it known that I, JOHN DAWSON, a citizen of the Dominion of Canada, and a resident of Walkerville, in the county of Essex and Province of Ontario, Dominion of Canada, have invented a new and Improved Window-Operating Device, of which the following is a specification.

, This invention relates to means for swinging windows, shutters and doors hinged on horizontal pivots, preferably along their upper edges, although the pivots may be positioned anywhere else with reference to the such closures, and its object is to provide a device of this character which shall be simple in construction, positive and simple in operation, and whose manufacturing cost shall be low.

This invention consists of a lever connected at one end to a window or other closure and which is pivoted intermediate its ends in a vertical guide so that its pivotal point may move up and down, together with means-for moving the opposite end of the lever, up and down at will.

This invention also consists in a slotted bar connected to the freeend of the operating lever, a wheel provided with teeth that may enter the slots in the bar, and means to support and turn said wheel to swing the lever up and down, together with means for guiding the slotted bar in engagement with said wheel.

In the accompanying drawings, Figure 1 is an inside elevation of a. window operating installation embodying this invention. Figs. 2 and 3 are sections on the line 2-2 of Fig. 1 showing the window in two positions. Fig. 1 is a section on the line A-l of Fig. 3. Fig. 5 is a 'section on the line 5-5 of Fig. 2. Fig. 6 is an elevation of the support for the operating shaft.

Similar reference characters refer to like parts throughout the several views.

The construction of the window frame, of the window, or the means for supporting the window in the frame form no part of this invention. The window and its frame may be of any desired character and the window may be pivoted along a horizontal line at any desired distance from its lower edge. In the drawings vertical pillars 1 are shown adjacent the lintels 2 and sills 3 of the window frames. Hinges 4 are shown connected to the lintels 2 and the window sashes 5, but any other construction may be employed. Extending between the lintels and sills, and connected thereto in any desired manner, are the guides 6 for the pivots of the operating levers. One manner of constructing and securing the guides consists in fastening channels 7 against angle bars 8, which, in turn, are connected to the lintels and sills by means of corner irons 9.

The operating levers 11 are preferably provided with pivot pins 12 which carry anti-friction rollers 13, slidably in the channels 7. Pivot blocks 14 may be connected to any desired portions of the window sashes at any desired distance from the ends there of, and to these blocks, the levers 11 connect. Secured to the pillars 1 are any desired number of bearings 15. for the shaft 16, preferably a tube, while bars 17 may be secured to the sills 3, if desired, to carry the shaft intermediate the bearings 15. On this shaft may be secured any desired number of toothed wheels18, preferably in the form of a plate of sheet steel formed with proper teeth, and mounted on the sleeve 19, having a flange 20. A ring 22 may be shrunk onto or otherwise secured to the sleeve 19 to hold the toothed plate in position.

A pin 23 may be employed to connect a channel bar 24 to the inner end of each operating lever, which channel bars are formed with slots 25 to receive the teeth of the wheels 18. Guide plates 27 mounted between arms 28 which are pivoted on the shaft 16, prevent thechannels from swinging away from the wheels 18. While this shaft 16 may be turned in any desired manner, it may be preferable to secure a bevel gear 30 thereto, which meshes with a bevel gear 31 on the upper end of a vertical shaft 32. At the floor or other position where the crank 33 can be easily reached, ,a shaft 3 1 may be mounted, on which, besides the crank, may be secured the bevel gear 35 which meshes with the bevel gear 36 on the shaft 32. It will be understood that this invention is not limited to this type of gearing for turning the shaft 16. v p The operating levers will be in the position shown in Fig. 2 when the window sashes are closed. To open the window sashes the shaft 16 is turned to the left, pulling down the bars 24 and the pivots 12, thus forcing out the lower ends of the sashes. When the parts reach the position shown in Fig. 3, the line of the thrust of the sashes along the levers 11 will be so nearly at right allgles to the guides 6, that very little stress on the slotted bars 24 will hold the parts in position. Suflicient stress is usually supplied by the plates27 which fall and grip the bars 24 below a line normal thereto from the center of the shaft 16. These guide plates 27 therefore also constitute locking evices for the window operating mechanism.

The number of window operating levers 11 will depend largely upon the length of the sashes, it being advisable to space the levers about ten feet apart for long sashes and to place one lever in the middle of each short sash, although this mechanism will also operate properly when the levers 11 connect to the ends of short sashes. The'proportions and other details can all be changed without departing from the spirit of my invention as set forth in the claims. While this device has been described as connected to a window sash, it will be understood that it is equally applicable to any other closures mounted on horizontal pivots."
