To all whom it'may concern:

Be it known that I, HOWARD S. HART, a

Citizen of the United States of America, residing at New Britain, Conn, have invented a new and useful Register and Ventilator, of which the following is a specification. My invention relates to certain new and useful im rovements in ventilators for the distribution of hot or cold air, and the same is particularly useful when employed in the side wall of a room or compartment. One object of the invention is to provide a construction which will offer a minimum of resistance tothe free flow of air therethrough from the air supply pipe with which the ventilator is associated. Another object is to improve the means for supporting and adjusting the valve so-called. Other objects will appear to the mechanic skilled in the art from a reading of the accompanying specification and an examination of the accompanying drawings, in which,

Fig. 1 is a front elevation.

Fig. 2' is. a rear elevation of the parts shown in Fig. 1.

Fig. 3 is a cross-section on the line 3-3 of Fig. 1.

Fig. 4 is a relatively enlarged cross-section on substantially the plane of line 4-4 of Fig. 5 is a relatively enlarged perspective of certain details.

In the particular form shown, I shall describe my invention as applied to what is termed a side-wall ventilator or register of the type designed to be located on the side wall of a room next to the floor.

In the drawings 1 is a casing, the front of which is preferably tilted back slightly in some cases, although not always. The cen-v tral portion of the casing is open and is provided with a removable front plate of rectangular outline. This front plate comprises the side border strips 2-2 connected to top and bottom border strips 3-4 respectively. The top and bottom border strips 3-4 are provided with rearwardly extending flanges 5-6. Arranged vertically and secured to said flanges 56 are thin bars 77 which are'placed edgewise to the direction of the How of air through the ventilator. As shown these bars are several times greater in depth than in thickness so as to not only afford the necessary strength but also to partially hide the air passage excepting when viewed from directly in front. It is manifest that these ranged reasonably close together, willofller obstruction to the vision when the register is looked at from one side while atno time will they offer any appreciable resistance to the free flow of air-betweemthemi Again such thin bars will not create eddy currents which tend to back up and baflie the passage of air through the ventilator. The lower edge of the border strip 4 may be provided with lugs 4 4 (see Fig. E2)- which pass into appropriate slits or openings in the casing 1 when the parts are assembled. The upper border strip 3 may be provided at its back with turn-buttons 8-8 which are arranged in one position to pass through corresponding openings in the casing 1, and each of which may be turned by a handle, such as bars; being of substantial depth and ar a rivet 11, to a valve plate 12. The area of the valve plate is sufficient to close the passage through the ventilator when said plate 12 is moved into the positionshown in solid lines in Fig. 3. 14 is a screw by which an operating handle 15 may be secured to the front of the valve plate 12. This screw passes freely through the plate 10 and screws into the plate 10 as best seen in Fig. 4. By turning the screw 14 the plates 10-10 will be caused to pinch on the bearing 9 with the desired degree of friction to hold the valve 12in any desired position of adjustment. The handle 15 is suitably shaped to pass through between two of the bars 7, and project sufiiciently far beyond the front to be easily acv The various afforded and accidental displacement of the bars will be avoided.v The bars 7 are preferably stamped out of sheet metal. Itwill be understood that I have shown the invention in its preferred form.

The valve is preferably a one-piece plate pivoted at its edge to swing, and the hinge pin or shaft is transverseto the direction of the cross bars so that the valve will perform the double function of a valve and a defiector i What I claim is: r In a face plate for ventilators and the like,

, a rectangular frame composed of top, bottom, and side border strips connected together, rearwardly directed flanges on the top and .bottom strips, a plurality of. thin cross bars, each bar being connected at-its ends to said rearwardly directed flanges, said bars being arranged side by side and edgewise with relation to the front of the plate to form free ventilating passagesya shaft bearing secured to the upper flange and positioned at the rear of saidcross bars, a plate valve and "a connection between said plate valve and said shaft bearing comprising jaws which embraces said shaft bearing,

the effective frictional tension of the same on said bearing, with a handle secured to said plate valve projecting forwardly between two of said cross bars for manual operation at the front of said plate, said jaw with means for operating said jaws'to vary 7 operating means serving also as the sole means of attachment of said handle to said valve plate.
