ELECTRIGALLY-OPERATED SASH-HOLDER.

Specification of Letters Patent. Patented Mjay 20, 1913 Application filed March 9, 1910.r Serial No, 548,134.

To all whom, it may concern.

Be it'known that I, HAROLD C. DEsBEoKnR, a citizen of the United States, and a resident of Schenectady, in the county of Scheneotady and State of New York, have invented certain new and useful Improvements in Electrically-Operated Sash-Holders, of which the following is a specification.

My present invention relates to an improved means for controlling the operation of a window fnom any part of the building in which the window is located or from any desired point, whether near or remote.-

The invention is especially useful in so far as it permits'a person lying in bed to wholly or partially close the window in case of cold or inclement weather or in the morn ing before rising, but other uses to which the invention might be applied will readily present themselves upon reading the subjoined description.

The invention might also be applied to permit a person at a distant point to open the Window and it 'will be understood that the apparatus might be applied'to either the upper or the lower sash of a window to con trol either the opening or. the closing thereof without departing. from the spirit of my invention.

A further object of my invention is to provide a device or apparatus of the above character which will be very simple and compact and consist of but very few parts and one'in which the desiredoperation ofclose proximity to the face of the sash 2 so thewindow can be absolutely relied upon.

The invention contemplates operating the window or. sash in one direction by hand a and providing means for automatically holding the window or sash in that position in combination with electro-magnetic meansv for rendering the said holding means inoperative and permitting the window to move in the'opposite direction until the said holding means are free from the electro-mag= netic device when the-sash is again held.

Theinvention consists in the improved combinations of devices and parts hereinafter more particularlydescribed and then specified in the claims. 7

In the accompanying drawings," Figure 1 is'ageneral elevation and partial section of a window framing and sashs'having my invention, in one way of utilizing it, applied thereto. Fig. 2 is, an enlarged transverse section through the window and showing the holding means in side elevation. Fig. 3

is a similar viewishowing the holding means in released position.

Referring to the drawings, 1 indicates a window frame and 2 the lower sash of the window, the upper sash being indicated at The said sashes are adapted to be raised and lowered in guides formed in the side .members of the window frame as is usual in the art. 7 In the embodiment of.my invention illustrated, the same is-applied to control the lower sash whereby the same might be closed at will from a distant point, but it will be understood that it might be applied to the upper sash or to both. When applied to the lower sash to permit it to be closed when desired, the sash is provided with weights 41 secured to'the, window as usual, butinstead of the weights being heavy enough to counter-balance the weight of the window and the force of gravity tending to close it, they are made light enough to allow the window or sash -.to gently fall of its own weight when not otherwise prevented, the weights in this instance being merely heavy enough to prevent the window suddenly dropping with a crash.

5 indicate's an eccentrically pivoted disk orcam mounted on a stud 6 rising from and. secured to a suitable base 7, the said base being fastened to the side of the window of the eccentric disk or cam 5 will be in that as the disk or cam turns about its pivot 6 in one direction or the other, the periphery thereof will become closer or farther away from the sash 2 according to the direction of rotation.

8 indicates an electrO-magnet mounted on the'base' 7 or otherwise suitably supported and having its core operatively connected with the eccentric disk .or cam 5 so that when the electro-magnet is excited the power thereof will be applied to rotate the cam, 5 about its pivot and turn the pe- .riphery of the cam away from the window. The electro-magnet is preferably provided with a movable core or plunger, the projectlever 9 or other suitable connection with the disk- 5. The elbow-lever is pivotally mountedat the elbow on a fixed stud secured to and rising from the base 7, the one arm beframe 1 in such position that the periphery ing end of which is connected by an elbow- I ing connected to the end of the magnet core or plunger by a pin and slot connection, the other arm being similarly connected to the cam or disk 5.

The electro-1nagnet 8 has its circuit extending to any desiredpoint in the room or building from which it is desired to control the either partial or complete closing of the window. At such point a push'button or other suitable means 10 for closing the electric circuit of the said magnet is provided. Electric energy for energizin the magnet may be furnished by a battery 11 or by preferencethe energy for that purposeis taken from the usual electric lighting circuit or other source. v

Normally the circuit is open and the parts in the position shown in Fig. 2 when, if the window is open, it is prevented from closing by the periphery of the cam 5 engaging the same and any tendency of the window to drop acts to turn the cam and efiect a bind ing action, the radius from the pivot 6. increasing by any such turning of the cam. If the window is closed,'it can be opened by hand as the cam is free to rotate in the oposite direction when the window is raised.

en the window is raised the cam*'automatlcally binds on the same and holds it in open position until the electro-magnet 8 is energized, at which time the core or plunger is drawn up and the cam rotated in a direction away from the window by means of the lever 9, the circuit being held closed until the window has dropped the desired distance, when, on opening the circuit, the cam will automatically hold the window in that position. It will be observed that the window might be allowed to close completely or might be arrested at any point of its descent.

12 indicates a lever fulcrumed on a spin dle 13 secured to the base 7, one arm of which is adapted to engage the projecting end of the core or plunger. By this means the window can be released from the cam 5 and allowed to close without the employment of an electric current, the lever forcing up the core and freeing the window in an obvious manner, which then drops by its own weight, any sudden dropping however being avoided by the counter-action of th weights 4.

Obviously by making the weights 4 heavier and reversing the holding means the window can be made to open upon closing the electric circuit of the magnet. It will also be understood that the apparatus might be applied to either the upper or the lower sash and to cause the same to be either opened or .16....1 or it might be applied to both sashes without departing from the spirit of the invention. Also it will be understood that various changes in the details of construction and operation might be resorted 'to without departing from the spirit of the invention.

Vhat I claim as my invention is:

l. A window controlling apparatus. comprising a cam adapted to engage a window and hold it in any, position throughout its travel, an electro-magnet normally inactive and connected with said-cam and a circuit closer connected in the circuit of said electro-magnet, whereby the same may be energized to retain said holding means free of the window until the window has traveled the'desired extent;

2. A window I controlling device comprising a cam adapted to hold a window in any position throughout its travel, an electromagnet adapted to rotate said cam to free the window, means pivotally connecting the movable part of said magnet and said cam and a circuit controller connected in the circuit' of said 'electro magnet whereby the same may be actuated to hold said cam free of the window. i 7

3. A window controlling apparatus com prising a cam adapted to engage a window and hold it in any position throughout its travel, an electro-magnet having a movable core andan elbow lever mounted on a fixed pivot and connecting said magnet and said cam, whereby the actuation of said core will rotate said cam and free the window.

4. A window controlling evice comprising a cam adapted to hold a window in any position throughout its travel, an electromagnet adapted to rotate said cam to free the window,means pivotally connecting said magnet and said eam and. a circuit closer connected in the circuit of said electro-magnet whereby the same may be energized to hold said cam free of the window.

5. A window controlling device comprising a cam adapted to hold a window in any positionthroughout its travel and an .electro-magnetic device pivotally connected with said cam and adapted, when actuated,

to rotate said cam to free the window.
