VENTILATOR.

Application filed latch 21, 1928. Serial 11 0, 545,489.

To all whom it may concern:

Be it known that ANDREW L. BIKER, a

' citizen of the United States,'and resident of Fai'rfleld, in the county of Fairfield and State of Connecticut, has invented certain new and useful Improvements in Ventilators, of which the following is a specification.

This invention relates to a ventilator, useful for many purposes, but more especially, adapted for use as a closure for transoms,

doorways, windows, panels, or the like.

An important object of the invention is to provide a ventilator which will be a novel, improved and compact article of manufacture, capable of insertion for use '1 with a minimum of effort by unskilled workmen, without danger of destroying the advantageous features for which the ventilator has been devised.

A further and important object is to produce an efiicient and reliable article of manufacture of the present character which will be simplicity itself in construction and which can be quite inexpensively manufactured, most all of the parts of the present ventilator desirably consisting of sheet metal.

A still further and important objedt is.

to provide a ventilator consisting of a frame having a plurality of louvers pivoted therein to turn on their axes and preferably so proportioned and arranged that when swung in one direction they will completely close the space within the frame and when swung in the other direction will leave passage ways between the respective louvers without opening a direct line of vision through the frame, and to equip the ventilator with dependable operating mechanism of improved design for swinging ,the

louvers to open and closed position, the

operating mechanism including simple and un que devices limiting thedeg ree to which the louvers can be turned on' their pivots.

lVith the above objects in view, as well as others which will appear as the specification proceeds, the invention comprises the construction, arrangement and combination of parts as now to be fully described and as hereinafterv to be specifically claimed, it

I being understood that the disclosure herein is merely illustrative and meant to, in noway hmlt the spirit of the invention, chan es in details of construction and arrangement of parts being permissible so long as within the scope ofthe appended claims. v

In the accompanying drawing forming a part of this specification,

'Fig. 1 is a perspective view of the novel ventilator, showing the louvers thereof in closed "position Fi .2 is an enlarged longitudinal sectiona view of the ventilator showing the louvers in open position;

Fig.- 3 isa view corresponding with the showing of Fig. 2, but disclosing the louvers in closed position, and frame members corresponding with those of Fig. 9;

Fig. 4 is an enlarged fragmentary perspective' view of the right hand end of the tailing the mechanism for operating the F ig.- 4, looking in the direction of the arrows; and r Fig. 9 shows a variant form of frame members.

The ventilator of this invention is constituted by .a frame of rectangular configuration, louvers pivotally mounted therein, and mechanism for swinging the louvers on their pivots to open and close the space within the frame.

The-,frame, as shown, sheet metal, it consisting of a top memberiij lO, bottom member 11, and side menrhers; denoted by l2 and 13, respectively.

As will be most clear from Figs. 1, 4 and '8, all of the members-of the frame are flanged plates, the top and bottom members having flanges, denoted

b7

14 and 15, respectively, extending at right-angles for the full lengthsof said members from their opposite edges, and the side members having flanges 16 "extending atfgfifiht-angles from their opposite edges and terminating short of the ends of the side members. The ends of the side members are provided s composed of bers to produce the frame will be best seen in Fig. 8. The opposite ends of the top and bottom members are arranged flush v 4 with the outer faces of the side members, a de' endable bearing for the sp1ndle29, and

the end portionsof the

flanges

14 and 15 are arranged contiguous withthe ends of the flanges 16 in ahgnment therewith, and

the flanges 17 are situated contiguous with the inner faces of the end portions of the top and bottom members, and between theend portions of the

flanges

14 and 15, re-' spectively. The connections between the members may be made in some other manner, as by means of rivets, but as.- -shown said connections are made by providing holes 18 in the flanges 17 and drawing the metal 0 the end portions of'the top and bottom members into the holes 18 and then spreading the drawn metal, -as indicated at 19 in Fig. 8. I have used the terms top, bottom and side'members for the sak'eof convenience. vIt will be understood that the arrangement as described could be reversed if this isfound desirable.

preferably being integral with and arranged at right-angles to the body portions: of the louvers. The louvers are pivotally mounted in the top and bottom members of the "frame in the manner best shown in Figs. 2 to 6, 1I1Cll1S1Ve. at is to say, each of the ears 22 1s provide with holes rotatably receiving a drawn portion 24 of the metal of the top said operating bar being arranged beneath the midwidths of said member of the frame, and each of the ears 23 is drawn as at 25 to rotatably enter an. annular flange 26 consisting of upwardly drawn metal of the bottom plate 6f the frame, the pivotal points for the louvers being arranged adjacent the opposite ends ofv the body portions thereof preferably close to ends. Numeral 27 denotes an operating ,bar for manipulating the louvers upon their pivots,

the ears 23 to slide upon the bottom plate of the frame, and each of said ears having metal drawn therefrom and 'rotatably entering holes 28 at uniform distances apart inthe operating bar. The mechanism for moving the operating bar longitudinally to turn the louverson .their pivots in a-manr ner which will be obvious, consists of a spindle 29 mounted in the flanges 1p adj acent one side of the ventilator and having a crank 30 and .a manipulating handle 31. Adjacent one of its ends the'operating bar is bent to general U-shapeas denoted at 32 to receive the crank, and .the position 'of that end of the bar, denoted 33, beyond the'spindle is insured bya'rod 34 situated directly" above the operating bar and having its opposite ends located in the flanges 15. a

The metal of the flanges 15 is drawn as de noted at 35- and 36,,respectively, to provide the -shaped part of the operating bar is preferably arranged about the crank so that the slight forward and rearward movements of the operating bar when movedlongitudinally to adjustthe louvers impart slight endwise movement to the spindle. Obviously, the operating bar will insure the spindle against displacement. The spindle has a reduced end 37 mounted in the bearing 35 whereby, the larger diameter of the spindle can limit rearward'movement of the same. Forward movement of the spindle is checked by' engagement of the operatingbar with the front flange "15 of thebottom member. Obviously, the position of the spindle in its bearings is thus insured.

Numerals

38 and 39 denote the body portions of end louvers fixed in the frame as by means of ears 40 desirably secured to the top and bottom' members by portions of metal drawn from the members and entering holes in the ears in about the manner-in which the ears-22 are secured to the -'top member. The body portion 38 is preferably arranged contiguous with the rear flange 16 at-the right endof the ventilator aiid the body; portion 39 is preferably arranged contiguous with the ront flange 16 at the left end .thereof.

Numerals

41 and 42 denote extensions upon the

louvers

38 and 39 respectively, which may extend obli uel from the fixed louvers inwardly oft e rame.

.In Fi 7 Ilhave shown the bearing 35 as arrange within an opening of the fixed louver 3 8, .and I have-shown the rod 34erten,din through said "louver, as Well as throug the flanges 15. The arrangement as illustrated is simply for the sake of convenience. I h

The throw of the crank 30 determines the distance the operating bar can move longitudinally, and hence limits the degree to which the louvers can be turned on their pivots, as will be obvious, and the operating ba r.,is of such length that when the louvers have been moved to wide open position, the end of the bar, denoted by 43, spaced from the crank will engage the extension of the 'louver 39. to furnish a positive stop tending to make stable the open positions of the louvers. See Fig. 2. The c osed position of the louvers is made stable by the engagement of the ex- 1 ber of the frame'upwardl to form the annul'ar flanges 26', I. rovi e a space 46 be- I tween-the ears 23 an .B'y drawin fin s es and bottom members of the frame. I desirably utilize rivets 44 as shown in Fig. 5

to first secure'the ears 22 to the top member of the frame. I then associate the'ears 23 the relative ositionsof the ears'23 and the ottomfmem fr. the metal of the; bottom memthe bottom member to aifordfclearance for the longitudinal sliding movements of the 0 rating bar upon the bottom member. T is will be most clear fromFig.6. i

The simplicity of the construction of the present ventilator is to benoted. The frame consists of but four sheet metal plates rigidly secured to each other. f The louvers each consist of' a single piece of sheet metalsuitably bent and mounted in the frame. And the operatin mechanism for manipulating the louvers s constituted by an operating bar and a crank with manipulating handle. The ventilator consistsofbut few parts and the'relative positions of all of the parts are insured, there being no liability whatever that any part can become dislocated or impaired. To incorporate the ventilator in its position of use all that is necessary is to fit the frame into a transom, doorway, window,

' panel, or the like, the flanges l4 and 15 serving the purposeof inclosing the ends of the louvers and the flanges 16 interlapping with the fixed louvers in such manner that the advantageous features of the ventilator are preserved.

' In Fig. 9 I have shown a variant form of frame members. In said figure, numeral 47 represents a top or bottom member, and 48 represents a side member. A portion of the side member and its flanges 49, are offset or drawn inwardly as denoted at 50 and the flanges 51 of the top or bottom member fit thereover toalig'n with the flanges 49. The

iconnection between the

members

47 and 48,

shown, is made b passing through all 0 said flanges, a bushing means ofa rivet 52 53, extending between the drawn in portions of the flanges 49 and through which the rivet extends, serving to allow the rivet to clamp the drawn in portions 50 and flanges 51 against each other. By the provision of elongated slots 54 in the drawn in'portions, the side member can be slightly adjustable in the top or bottom member. In the present form of the invention the bushing 53 can be located to serve the purpose as described of the rod 34.
