HOT-AIR REGISTER.

Specification of Letters Patent.

ratenteot April 2, 1907.

Application filed October 28, 1905. Renewed February 18. 1907. Serial No. 358,114.

a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in hotair registers, and pertains more particularly to a device applied to such a register whereby the heated air, which usually contains more or less dust and sooty particles, is deflected away from the wall near which the register is located into the room, the object of so deflecting the air being to prevent the dust from settling on the wall and to cause a diffusion of the hot-air current throughout the room.

My invention comprises for this purpose a disappearing iood, which not only deflects the air, as above stated, when the hood is raised, but also closes the register-opening when retracted. The hood is arranged to disappear beneath the register-grating when not in use as a deflector, leaving the floorspace above the register clear and unobstructed.

Another feature of the invention lies in the construction of the hood whereby it auto matically spreads out fan-like at the sides when raised, so as to give the hood a dished or shell-like shape. The spread-leaves at the edges of the hood prevent air from escapinsure that all the air will be deflected. to ward the center of the room.

With these and certain other objects in view, which will appear later in the specification, the invention consists in the devices illustrated in the accompanying drawings and the equivalents thereof.

In the drawings, Figure 1 is a perspective of the hood and its operating mechanism. Fig. 2 is a vertical section taken on the line a; m of Fig. 5. Fig. 3 is a front view. Fig. 4 is a section taken on the line g 3/ of Fig. 5, showing the hood retracted; and Fig. 5 is a top plan view of the register with. the hood retracted, the grating of the'register being broken away in part.

As is shown in the drawings, the particular 111g around the edge of the hood proper and embodiment of my invention herein illustrated consists in the usual register-grating 1, which may be preferably provided along one edge with a slot l, which. receives the curved sheet-metal hood 2. The hood when raised, as shown in Fig. 2, deflects the air from the register toward the center of the room and when lowered, as shown in Fig. 4, closes the register. The hood may be raised and lowered by any suitable mechanism, such as that illustrated in Fig. 4, in which 3 is a toothed rack arranged to slide back and forth in suitable bearings 3 carried by the grate 1. The rack 3 preferably carries a projecting pin 4, adapted to be moved back and forth by the foot. A pinion 5, fixed to a suitably-supported transverse rocking-shaft 6, meshes with the rack 3 and is rotated by it when the rack is moved back and forth. To the rock-shaft 6 is-secured a pair of radial arms 7, pivotally connected at their outer ends to the hood 2. Moving the pin 4 to the right in Fig. 4 actuates the arm 7 to raise the hood, and movement of the pin 4 to the left retracts the hood. The pivotal connection between the arm 7 and the hood may be of any suitable construction, but I prefer to provide on the end of the arm 7 a pin 7*, engaging the slotted bracket 2, secured to the hood 2. This pin-and-slot connection permits a freedom of motion of the hood when being raised or lowered which would not otherwise be obtained and enables the hood to be raised or lowered easily.

To facilitate the closing of the hood and to yieldi'ngly hold it in its closed position, I preferably secure to the ends of the shaft 6 short radial arms 8, connecting the ends of these arms to the grate 1 by means of helical springs 9. The tension of the springs 9 serves to hold the arms 7 in their raised or lowered positions to retain the hood 2 yieldingly in its retracted or projected position.

Pivotally secured to the sides of the hood are curved wings or blades 10, adapted to enlarge the deflecting surface of the hood, and thus prevent the air-currents from escaping around the ends of the hood. These wings may be provided with springs .11, Fig. 5, for i automatically spreading them when the hood is raised; but I prefer in practice to simply mount the wings 10 upon the hood 2 by loosely pivoting them, so that the wings will drop to their spreadposition by their own weight. If desired, one or more additional wings 12 may be similarly pivoted to the wings 10. Suitable stops 13 prevent the wings 12 from spreading too far.

In order to prevent any undesirable play or relative movement of the hood and the rock-shaft, I prefer to connect the lower end of the hood with the shaft by means of the helical spring 14, whereby the hood. is yield: ingly supported when in lowered position and when in open or raised position is caused to remain upright to permit the air-current to pass freely through the grating. hen the hood is retracted, as shown in Figs. 4 and 5, the wings automatically fold upon passing down through the slot 1.

By the means above described I have produced a disappearing hood for hot-air registers that offers no obstruction to the floor space when closed, automatically spreads when opened, and is raised and lowered by the simple pressure of the foot against the What I claim as my invention, and desire to secure by Letters Patent, is as follows:

1. The combination with the grate of hot air register, of a deflecting-hood adapted to project above the grating when opened and to disappear beneath the grating and shut the register when closed a foot-pin and a rack carried by said pin; a roclvshaft carrying a pinion engaging said rack; radial arms fixed to said rock-shaft and pivotally secured at their ends to said hood.

2.The combination in a hot-air register with an approximately horizontal stationary grating extending across a register-opening, of a heat-deflector comprising a plate capable of being projected above the grating and an automatically folding and unfolding wing secured to at least one edge of the plate and carried thereby for reducing or enlarging the deflecting-surface.

3. The combination with a stationary grating, of a combined deflector-plate and closure therefor, the deflector-surface adapted to be projected beyond the grating .or withdrawn behind the same, mechanism for projecting the deflectorsurface or for retracting it, means for loosely connecting the mechanism and plate, and tension means extending between the plate and mechanism.

4. In a register, the combination with a stationary grating, of a deflecting hood adapted to project above the grating when opened and to disappear beneath the grating and close the register when in lowered posi tion, wings pivotally mounted on the hood and adapted to automatically expand when the hood is in raised position and to fold over the hood when the latter is in lowered position.

5. The combination with a register, of a deflector adapted to project in front of the register, when in extended position and to be withdrawn within the register to close the latter when in retracted position, a rod-and lever connection for effecting the actuation of the deflector and resilient means placed under tension by the operation of the rod-andlever connection for yieldingly retaining the deflector in any of its positions.

6. A deflector mechanism for dischargeopenings comprising a suitable supported rock-shaft, arms projectin from the shaft, a hood to which the free ends of the arms are loosely pivoted, and a tension means connecting the hood and shaft.

7. A deflective mechanism for dischargeopenings comprising a suitably-supported rock-shaft, arms projecting from the shaft, a hood to which the free ends of the arms are loosely pivoted, cranked arms on the shaft, tension means connecting the arms and the wall of the opening.

8. Adeflector for openings comprising a hood, means for projecting the hood from and withdrawing it into the opening and overlapping wings pivotally secured to the opposite edges of the hood, the wings adapted to expand when thehood is projected and to overlap each other and the hood when the latter is withdrawn into'the opening.

9. A deflector for discharge-openings comprising a hood, mechanism for projecting the hood irom the opening to open the opening and for retracting it into the opening to close the latter and wings pivotally secured to the opposite edges of the hood, the wings adapted to expand as the hood is projected from the opening, the outer edges of the wings adapted to engage the wall of the opening when the hood is retracted to effect their closing.

In testimony whereof I aflix my signature in presence of two witnesses.
