My invention .hasfor its object to. provide an extremely simple and highly eflicient shutter-equipped grille, intended for general use in connectionwitha stack, flue orthelike and especially. well: adapted for use in connection with'the stack of cabinet or concealedmadiation. for controlling the hot. air discharged from the heat exchange unit therein, or in cutting the same off entirelywithoutthe use of a valve for said unit.

To the above end, generally stated, the invention consistsof thenovel devices and combination ofdevices hereinafter described and defined in the claims. 7

In the accompanying drawings, which illustrate the invention,likecharacters indicate like parts throughout theseveral views.

Referring to the drawings Fig. l is a. face view of anoutlet grille, in which the invention is tembodied', mounted 'in the discharge passageway ofthe stack. of a heat unit; i

Fig. 2 is azback viewof the grille-removed from I thestack Fig. 3' is a-fragmentary view: showing the upper left hand cornerportion of the grille as-shown in Fig. 2, on anenlarged scale with some parts sectioned to'show. the bearing for the shutter hinge rod;

Fig. 7 is a fragmentary view principally in horizontal section taken on" the-line 7-7 of Fig. 1,.on an enlarged scale. 1

The outlet grille 8, which the invention is embodied, may be used in" connectionwith either cabinet or wall radiation and in the drawings the numeral 9 indicates a fragment of a sheet metal cabinet having at its top a discharge passageway in which said grille is mounted. When the grille 8 is used in connection with wall radiation the numeral 9 would indicate one face of said wall and the grille. 8.would be connectedto thedischarge end of. a. stack. as illustrated, by broken. lines in Fig. 4 and indicatedflby the. numeral 10. The grille r8 isformed from a flat sheet of metal having a 'multiplicity of. horizontally spaced relatively narrow and vertically extended slot-like openings 11 withl'relatively narrow intervening columns 1 2.. Said. grille 8 has an imperforate, marginal. portiontthat completely" surrounds the openings 11. In

forming the openings 11. in the grille 8 the displaced metal is pressed laterally. rearward to form endless reinforcinglflanges 13 that extend completely around'each ofsaidopenings and perpendicular to said grilleI Each flange 13. is reduced inxheight. at each end of the respective. opening 11,,as shown .inFigs. ilto. 7, inclusive, .and indicated by the numeral 14. to. facilitate the stamping of. the. flanges from the body ofthergrillel. Obviously, the

fiangesl? greatly rein-force the columns 12 and strengthen the grille .8.

The grille ,8. is provided atitsbacklwitha rectangular, angle frame 15 'whicliisurrou'nds the series of openings; 11. One,flangeofthe' frame- 15 rests. directly .on the. back0ffthe grille. 8. at the -imperforate marginal portion and is. rigidly secured theretoby. welding or otherwise and the other. flangeflthereof; ex.- tends perpendicular tosaicll grille and is spacedfromtheends. of the openings 11 A. shutterv 16 .is provided for. controlling ,or varyingfthe vvolumeflowof hotain outward through .the, grille: 8. or. fon. entirely closing the same. Thisshutterldis formedQfroma sheet. of: fiat. metal, closely zfits...witliin-: the frame, 15. andis rigidly secured, at its upper edgeportion, toa horizontalhinge rodllZ the endsofwhich arej ournaled inbearin blocks 18 .detacliably secured byv screws 19 .tothe inner faces ofthe uprightmembers oftheframe openings 11 in said grille and a vertical slot 22 in the shutter 16 and is pivoted to and between the side members of a U-shaped bearing 23 on the back of said shutter. The way as shown is in the form of a relatively narrow upright plate 2& which bears aaginst the outer face of the grille 8 and is frictionally clamped thereon by a pair of screws 25 which have screw-threaded engagement with an anchor plate 26. This anchor plate 26 bears against the rear longitudinal edges of certain of the flanges 13 at the longitudinal edges of the opening 11 through which the lever handle 21 extends. Vertical slots 27 are formed in the way 24: and anchor plate 26 and aligned with the opening 11 through which the lever han dle 21 extends with freedom for vertical swinging movement.

By reference to Fig. 4, it will be noted that the anchor plate has on its upper end a forwardly projecting stop member 28 which rests on the top of the respective flange 13 and holds the way 24: against downward shifting movement on the grille 8. The shuttor 16 is gravity closed and for holding the same in different open positions there is provided two laterally spaced rows of vertically spaced ratchet teeth 29 and a cooperating transverse dog in the form of a pin 30. The

ratchet teeth 29 are integrally formed with the way 24 on the back thereof, extended into the respective opening 11, engage the columns 12 at the sides thereof and hold the way against angular or horizontal edgewise movements on the grille 8 The dog 30 extends transversely through the lever handle 21 with its end portions arranged to rest on any one pair of transversely aligned ratchet teeth 29, see Figs. 6 and 7. During the opening of the shutter 16 by the lever handle 21 the dog 30 will freely ride overthe ratchet teeth 29 and automatically interlock with the pair of ratchet teeth opposite which said dog is positioned when said lever is released. The free or outer end of the lever handle 21 is transversely enlarged to form a finger piece 31 which when the shutter 16 is closed engages the way 24 at each side of its slot 26 and prevents said lever from swinging entirely within said way.

By the use of the above described shutterequipped grille the temperature in a room may be controlled, at will, by opening or closing the shutter 16 to a greater or less degree to vary the volume flow of hot air through said grille or by completely closing said shutter the discharge of hot air may be completely cut off.

The above described shutter-equipped grille has a very neat and artistic appearance, is simple to operate and highly efficient in its action.

What I claim is:

1. The combination with a grille of the class described, of a shutter hinged to the grille, a way in the form of a plate having a slot, means for frictionally clamping the way on the grille, teeth on the way extending through the grille and engageable therewith to hold the way against shifting movement on the grille, and an operating lever attached to the shutter, working through the slot in the way and having a dog cooperating with the teeth on the way for holding the shutter in different open positions.

2. The combination with a grille of the class described having a pair of laterally spaced flanges and a passageway therebetween, of a shutter hinged to the grille, a wav in the form of a plate having a slot aligned vith the passageway, clamping means for securing the way to the grille and engagin the flanges as a base of resistance, teeth. on the way, and an operating lever attached to the shutter working through the passageway and the slot in the way and having a dog cooperating with the teeth for holding the shutter in different open positions.

3. The structure defined in claim 2 in which the teeth are arranged in two rows that extend into said passageway, engage the grille at said passageway and hold the way against shifting movements transversely of the passageway.

4. The combination with a grille of the class described having on its back a pair of upright laterally spaced flanges and a passageway therebetween, of a shutter hinged to the grille, a way in the form of a plate at the face of the grille and having ratchet teeth, an anchor plate bearing on the flanges, screws connecting the way and anchor plate for frictionally clamping the way onto the face of the grille, and the anchor plate onto the flanges, said way and anchor plate having slots aligned with the passageway in the grille, and an operating lever attached to the shutter, extending through said passageway and the slots in the way and anchor plate, and having a dog cooperating with the ratchet teeth for holding the shutter in different open positions.

5. The structure defined in claim 4 in which the anchor plate engages a part on the grille to hold the way against downward shlfting movement on the grille.

6. The structure defined in claim 4: in which the ratchet teeth are arranged in two laterally spaced rows which extend into the passageway, engage the grille on opposite sides thereof to hold the way against shifting movement transversely of said passageway.

In testimony whereof I aiiix my signature.

EDWARD H. SEELERT.
