WINDOW-CONTROLLING DEVICE.

T0 aZZ whom z' may concern:

Be it known that I, EMILIO FONTQUERNI- VVina, a citizen of the United States, residing at New York, in the county' of New York,

VStateof New York, have invented certain new and useful Improvements in Window- Controlling Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the lart to which it appertains to make and use the same..

. The present invention relates to 'new and useful improvements in devices for opening or closing windowsV or doors, and it'is morel particularly directed to vthe provision ot such a device operable from a point remote from the window or door to be actuated.

' It is in general the object to simplify and otherwise improve the structure and to increase the efficiency and ease of operation ofl devices of this character, and it is. more particularly an object in this connection to provide an operating device for windows which ma be associated with the ordinary frame an sashes of a window in a most ready manner.

A further and important object resides in the provision of an arrangement wherein the window or other member to be operated is locked against movement in either direction except during its movement by said actuating means. h

A still further object resides in the provision of a device of the present nature whose operation may be electrically' controlled from a point remote from the member to be moved, whereby said windows or the like may be simultaneously closed upon the occurrence of storm or for any other reason. l l l if ith the above and other objects and adl -vantages inl view, the invention resides more particularly in the novel combination, for` mation and arrangement of parts hereiii after described and particularly pointed out in the appended claims.

In the accompanying drawings:

zontally through the operating shaft and clutch mechanisms.

Fig. 4 is a transverse sectional view on the line 4.-4 of Fig. 1.

Fig. 5 is a fragmentary sectional view on the line 5 5 of Fig. 1, and showing one of the circuit breaking switches operated by the sash frames, and

Fig. 6 is a wiring diagram for the device.

' Fig. 7 is an enlarged detail sectional view of the extension sections" of the motor .shaft 'f and casing. l n

Fig. 8 is a detail section taken longitudi' nally 'of one of the clutch sleeves.` Referring now more particularly to th 'accompanying drawings, 5 designates generally a window frame in which is slidably mounted the upper and lower sash- members 6 and 7 respectively, the sash frame being of generally conventional nature, providing spaces of conventional nature between' its inner vside walls and the building structure,

`said spaces being usually employed as wells chain belts 11 by `outwardly projecting bracket arms 13 while the lower sash is secured tothe inner chains 12 by relatively shorter outwardlyprojecting bracket arms 14 at its four corners, the bracket arms 13 and 14 extending through slots in theI inner side walls of the window frame whereby said sash members may have sliding movement throughout the vertical length of the frame. i

For operating these chains to control the positions of the sashes, a motor casing 15 is mounted under the central portion of the frame and has casing'sleeves 16 extending longitudinally from its sides in which is mounted the motor shaft 17 carrying the armatures of a pair of motors 17" and 17b *arranged to run in opposite directions.

casingsleeves 16', and disposed in axial aline@ v ment with the sleeve is the hub 19 of a Sprocket wheel 20 about which is trained the lower end of the inner chain belt 12 at the corresponding side of the window frame. Journaled inthe hub lf) and in a bearing bracket 21 disposed outwardly thereofl is the shaft of an idle sprocket wheel 23 about which is trained the adjacent outer vchain belt 11. The inner chain belt 12 at the other side of the frame is trained about a sprocket wheel 24 idly mounted on theV outer end of theadjacent casing sleeve 1,6, and the lower end of the outer chain belt 11 is trained about a sprocket wheel 25 whose hub is in axial alinement with the casing sleeves 16 and is journaled in a bearingvbracket 26. The motor shaft 17 extends outwardly of the nid of the sleeve casings 16 into squared recesses 27 in the hubs of the sprocket wheels 20 and Thus by clutching the shaft to 'either of the sprocket wheels, thecorrcspending chain belts may be actuated by operation of the motor to move either window.

The clutch mechanisms for accomplishing this comprise a pair of clutch sleeves 23 and 28 respectively splined on the end portions ofthe motorshaft 17 and having their outer faces squared to engage slidably in the squared recesses 27 of the ysprocket wheels 2() and 25 respectively and in the squared recesses 30 in the outer endsof the sleeve casings 16. The clutch members areeaeh provided with a central annular groove 3l, in which is engaged the upturned spanner arms 32 at the endlof a single actuating rod 33 which extends parallel to the engine sha l't and jasing sleeves, being normally urged to a position wherein the clutch sleeves 28 and 28 are held between the sprocket wheel hubs and casing sleeve ends by springs 35 sccured to theI rod and to later described solenoids 36 and 37 in which the rod slidably mounted. ll'ith cach of the clutch sleeves held in this position its squared portions engage in both the squared recesses 27 and 3() and thus hold the sprocket wheels 20 and 25, preventingr rotation of the wheels in either direction to lock the sashes in any positions which they may assume. To actuate said clutch members to operate the window sashes the solenoid coil 36 surrounds the rod adjacent the. sprocket wheel 2() and the sole noid 37 surrounds the rod adjacent the sprocket wheel 25, these solenoids being adapted upon energization to shift the rod in either direction. Upon said shifting movement of the rod toward the sprocket w-heel 2O for instance, the clutch sleeve 28 will disengage from the recess 30 of. the casing section 1.6 and will move farther into the recess 270i the sprocket wheel 20. At the same time, the clutch sleeve 28 will move awa-y from the recess 27 of the sprocket wheel 25 and its squared portion adjacent the casing sleeve 16 will move into a cylindrical inner portion of the recess 30 of said casing sleeve, whereby rotation of the motor shaft is permitted, the` sprocket wheel `25 being idle. rlhus driving rotation of the motor shaft 19 in either direction will raise or lower the sash 7 and upon shifting movement of the rod in an opposite direction effected by the solenoid 37, the upper sash may be moved in a similar manner.

An exceedingly simple structure has thus been provided whichaffords absolute control for movement of the sashes and the win. dow or any other shiftable members, and it is noted that the present device may be associated with an ordinary window frame in al most ready manner. The chain belts at both sides of the sashes assist in procuring a proper slidingmovcment thereof, and the sashes, when their controlling sprockets are released, are held against undesired sliding .movement by friction, or by sash weights 39 secured to theL belt stretches opposite those to which the bracket arms 13 andu 14 are secured, it being obvious however, that but a single chain may be employed for each sash.

As shown in the diagra-inFig. 6 there is a source of electricity illustrated as a generator 44, which is electrically connected by means of a wire 43 with both of the motors 17XL and 17". 'Between themotor 17 and the solenoid 37 there is an electrical connection 41, including apair of switches 5l) and a third switch 45, connected in series. and between the motor 17b and the solenoid 3(3.lthere is a similar connection 42 including two switches 50 and a third switch -l-H. also connected in series, the switches 45 and 43 lyingbetween the switches 50 and lthe respective solcnoids. .Ik wire 43h, in circuit with which there is a switch 46, connects the solenoid 37 with the connection 42 between the switches 48 and 50, while a wire 43", having a switch 47 in circuit therewith connects the solenoid '36with the connection 41 between the switch 45 and the switches 5l). loth of the solenoids are ygrounded with the generator as indicated at 43. From the foregoing it will be seen that either solenoid may be connected in series with either motor.

ln the assembled apparatus, the switches 5() are located one at each'limit of movement of each sash, and. as illustrated in Fig.l 5, they are constructed so as to be engaged and opened by projections 51 011 the sashes, so that when the sashes have reached the limit of their movements the circuits in which these switches are included will be broken.

Referring again to Fig. 6, it willl be seen that with the switches 50 in the connection '41 closed and the switches 46, 47and 48 current will flow from the generator 44, through the Wire 43 to the motor 17a; thence through the connection 41 to the solenoid 37, through the latter and back through the ground 43 to the generator.

With the switches 45, 47 and 48 open and theswitch 46 closed, current will flow from the generator through the wire 43 vto the motor 17", thence through the connection 42, the switches 50 therein being closed, to and through the wire 43b to thevsolenoid 37 and thence throughthe ground 43 to the generator.

lVith the switch 47 closed and the switches 45, 46 and 48 open, current will flow from the generator through the wire 43 to the motor 17 a, thence through the connection 41 to and through the wire 43c to the solenoid 36, and thence through the ground 43 to the generator.

With the switch 48 closed and the switches 45, 46 and 47 open, current will flow from the generator through the wire 43 to the motor 17', thence through the connection42 to the solenoid 36 and inallyv from this solenoid through the ground to the generator.

The switches 45, 46, 47 and 48 thus'may be termed operating switches, the switches 45 and 46 controlling the movement of the one of the sashes, while the switches 47 and 48 control the movement of the other sash.

It will be further understood that the.

motor may be placed at any desired point in the arrangement Ishown, and that the shaft 17 which in the present arrangement 'forms the armature shaft of the motor, may

pendent of any other function. LTo render the device adjustable for various sizes of windows, the lengths of the chainsmay be varied with respect to varying heights of the Windows and the shaft and casing 16 and 17 may be provided with extension portions compensating for varying widths of windows.

Vhile the apparatus has been described as embedded in the window frame, it may obviously be positioned at the outside of an ordinary window frame, its position within the framehowever being procurable with existing window structures as heretofore set forth.

lVhile I have shown my device as associated with a window for procuring vertical closing movement of the sashes thereof, it is obvious that the device may act to move closure members either vertically or horizontally.

While I have shown and described a preferred embodiment of my invention, it is obvious that various other changes and modifications of structure and arrangement may be resorted in to meet the different conditions of use without departing in any manner from the spirit of the invention, as defined by the accompanying claims.

What is claimed'is: v

1. A device of the class vdescribed comprising a drive shaft, a pair of drive mem bers, a pair of stationary locking members,

clutch members splined on theI shaft, a rod connecting said clutch members, means normally urging said clutch members to clutching engagement with both the drive mem `bersand locking members and means for shifting said rod to disengage the clutch members from clutching relationwith the locking members and with one of the drive members.

2. A device of the class described including a drive shaft, a drive member, a locking member, a clutch splined on the drive shaft and normally in engagement with said drive and locking member, a slidable rod connected with said clutch for operating it, means resiliently urging said rod to position holding the clutch in engagement with the drive and locking members and a solenoid coil on said rod for shifting it to disengage the clutch'from the locking member.
