HUGO JOSEF, OF CLEVELAND, OHIO.

VENTILATOR.

Application filed June 2S, 1923.

l 1o all whom t may concern.'

Be it known that I, HUGO JOSEF, a citizen of Austria, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Ventilators, of which the following is a specification:

The present invention relates to certain new anduseful improvements in ventilators for buildings and like structures and has .for its object to provide a device of this character which embodies novel features of constr-uction, whereby a supply of fresh aircan be obtained within a building without the necessity of opening any of the usual doors or windows.

The invention also aims to provide a ventilat-ing device which can be regulated by .the occ-upant of the building to control the quantity of fresh air entering the building, and which will supply fresh air without letting in rain or snow in stormy weather.

Further objects of the invention are to provide a ventilating device which iscoinparatively simple and inexpensive in its construction, w ich can bereadily installed in a building, and which is at all times under the erfect control of the occupant of the built ing.

With the above and other objects in view,

the invention consists in certain combimovable panel which normally closes the.

outer end of the ventilator opening.

Figures 1l and 12 are detail views of the connecting bar for causing the' two sets of shutters to operate in unison when the elec- 'tric fan is not in use.

Corresponding and like parts are referred to throughout Vthe following description and on Vall .of the views of the drawings by like reference characters. v

The ventilator is adapted'to be installed in the wall of a building or like structure and provides an effective means for per mitting fresh air to enter the buildingwithout the necessity of leaving any doors or windows open. This makes it possible to properly ventilate the building in stormy weather without permitting the entrance of rain or snow into the building, and the building can also be properly ventilatedwith all of the doors and windows closed and locked, so that unauthorized 'entry into the building is difiicult and can only be accomplished by breaking open some part of the building. j The ventilatingopening A is formed in a frame B which is built into a wall of the building and which may be of any suitable construction, As indicated in aA general obvious, however, that when the arms 3 are y Vswung inwardly and disengaged `froin the Way by Figure 3, the frame B may be at ythe upper portion of a` casing C within which the windows D are mounted, although this is not material or essential to the in-V vention and the Ventilating opening can be formedV in the wall of thebuilding in any suitable manner. Y Y

The Ventilating opening in the present instance is horizontally disposed and of anV elongated formation, and the outer end of from the frame B. The slats in the 'outer panel thus tend to prevent rain or lsnow from entering the opening with the 'supply of fresh air, while the lslats ofthe Vinner panel serve to direct the fresh air down wardly as it enters the building.

The outer panel E is provided at the four corners thereof with swinging arms 3 which are hinged'to the panel at l. The swinging ends of the arms have notched portions which' are adapted to engage lugs 5 secured to the top and bottom walls respectively of .the ventilatin-g opening for thepurpose of securing the panel in'position. It will be lugs the panel eanjbe bodily removed from position. rlfheinner panel F may be locked 'in' position in any suitable manner, although foi-illustrative purposes one end thereof is sho-wn as provided:with ,longitudinally extending pins 6- which are adapted to enter corresponding openings in the frame, while the. other end of the panel is provi-ded with a lconventional key controlled lock 7'. `When the bolt of the lool: isjretracted the corresponding end of the panel can be pulled out ofthe fra-ine after which the panel can be given a longitudinal movement to disengage s the-'pins' 6 from the sockets or openings.

outer panel E. is provided with a piecev of screening or woven wire fabric 8 which .Y extend-'s asi-oss the openings thereof, softha-t Y the entranceof insects or largey particles of v foreign matter into the 'ventilating' opening is prevented. The back of the outer panel is also* provided withv a series of lshutters 9; shownonthe drawing, there are two sets' of the shutters 91, each set con-taining three' shutters andthe shutters being arreleasing the ranged in an end' to end relation. Each of thel shutters is provided at the ends thereof withrpivot studs 10 which` engage bearings 11, and by swingingthe shutters into Van open or a closed'positionthe ventilation can be controlled." rlhe'swinging edges of the Y shutters are provided with arms 12, and the arnisrof the Ytwo setsk of Vshutters are connected by the bars 13 and 13V so that the shutters of cach set can be operated in unison. Y

The control bar 13 for one'set of the shutters is connected at its lower end to a crank arm 14 on a rock shaft 15 which is journaled insuitablebearings 16 on the lower edge of the panel. VrEhe end of the rock shaft is provided,witlia crank portion 17 which env gages arslot 1311i a plate'19 which is secured.A Y

however, that byV movingthe Vrod 2O VVand plate 19 downwardly the `rock'shaft 15 will be rotated tov open the' shutters and the amount ofventilation which is obtained is controlled by the degree to whichthe shutters are' opened. The slii'i-tters may beeither partially or completely opened andthe ventilatioii of the building is thus entirely under the control ofthe occupant.

'The control rod 20` extends downwardly through a vsuitable passage inone. side Vof the casing C, and` has the lower 'end' thereof Y connectedtfo a slide 22`w-hicli is mountedV in a frame 23.

','The roundedV nose of theV spring actuated pawl interlocks with 'the notches to prevent acl Y cidental movement of the slide bar, although the slide bar can-be forcibly moved when it is desired to change` the adjustmentthereof.

-Whenso desired the two sets ofshutters can be connected so that they operate in unison, and are bothcontrolled by the handle 26. For thispurpose two of the shutters 9 which Ahave an end to end rela.- tion are connected by a bar 35, such as is shown by Figure 11. This connecting bar 35 may have the middle portion thereof arched, so that Vit will straddle the bearings 11, and the ends thereof are detachably secured to the respective shutters so that the shutters will operate in unison. The shutters of each set are operatively connected by the arms 12 and control bars 13 and 13a, so that when the connecting bar 35 is in place the two sets of shutters will move in unison and be both controlled by the single handle 26. The connecting bar 35, however, can be readily removed when it is desired to provide a separate control device for each set of the shutters.

Under some conditions it may be found desirable to associate an electric fan with one set of the shutters so that a forced circulation of air can be obtained. For this purpose a fan housing 33 may be suitably positioned within the ventilating opening and a suitableelectric fan 34 mounted therein. The fan may be controlled by a conventional electric switch 37, which is shown on Figure 3 of the drawings as mounted upon one side of the casing C, just above the plate 27 of the mechanical control device for the shutters. The wires 33 for the electric fan lead to this switch 37, and a pair of solenoids are interposed in the fan circuit, so that they will be energized when the fan is ruiming. These solenoids are mounted upon a shelf 40 which projects upon one side of the fan housingT 33, and an armature 41, is arranged above thevsolenoids so as to beV drawn downwardly thereby when the solenoids are energized. A stem 42, which is rigid with the armature 41, is slidably mounted within the shalf 4() and a guide member'V 43 which projects from a side of the fan housing' at a point above the solenoids. The lower end of the stem 42 is provided with a forwardly projecting plate 44 which has a slot 45 therein, said slotreceiving a pin 4G on the control bar 13a of one set of the shutters. A coil spring 47 which is connected to the upper end of the said control bar normally tends to hold the shutters in a closed position.

The connecting bar 35 for causing the two sets of shutters to operate in unison is, of course, removed when the fan device is used. The fan device can be readily installed in the' casing, and it will be obvious that when the switch 3T is open and the fan at rest the' shutters will be held in a closed position by the coil spring 47. lhen the switch is closed to put .the fan into operation the solenoids 39 are energized and the armature 41 drawnfdownwardly thereby. This moves the stem 42 and the slotted plate 44 downwardly, with the result that the control bar 13a is moved downwardly and inwardly to open the shutters. The shutters are thus automatically opened as an incident to putting the fan into operation, and in a like manner the shutters are automatically closed when the fan is stopped.

A ventilator of this character enables an abundant supply of fresh air to be introduced into a building, and at the same time dust, insects and particles of foreign matter are excluded. Proper ventilation is also possible without leaving the doors or windows open, thereby enabling fresh Vair to be admitted to the house when all of the doors and windows are locked to prevent entry by an unauthorized person.

lVhile certain preferred forms and embodiments of the invention have been shown on the drawings and described for illustrative purposes, it will be understood that many modifications and changes can be made in the details of construction without depart-- ing from the spirit of the invention and all within the scope of the claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A ventilator including an open ended casing, a removable panel fitting across the opening of the casing, a set of shutters mounted upon the inner face of the panel, lugs projecting from opposed interior walls of the casing, swinging arms carried by the panel and adapted to extend into the casing so as to be swung into and out of engagement with the said lugs, and means for controlling the shutters.

2. A ventilator including an open ended asing, removable panels iitting across opposite ends of the casing, lugs projecting from opposed interior walls of the casing, swinging' arms carried by one of the panels and projecting into the casing so as to be swung' into and out of engagement with the lugs, means controlled from the outside of the. casing for securing the other panel in position, a set of shutters upon one of the panels, and means for controlling the shutters.

3. A ventilator including a pair of swinging shutters arranged in an end to end relation, pivot members at the ends of the swinging shutters, and a detachable connecting bar extending between the adjacent ends of the shutters and formed with an arched intermediate portion spanning the pivot members and providing a` clearance space therefor.
