AIR-BOX FOR RADIATORS.

SPECIFICATION forming part of Letters Patent N0. 585,708, dated July 6, 1897. Y Application led July 14,1896. Serial No. 599,144. (No model.)

To @ZZ whom it may concern:`

Be it known that I, ROBERT ScoTT, a citizen of the United States, residing at Glenside, in the county of Montgomery, State of Pennsylvania, have invented a new and useful Improvement in Air-Boxes for Radiators, which improvement isfully set forth in the following specification and accompanying drawings.

My invention consists of a novel construction of air-box for radiators which is automatic in its action and possesses means by which access can be readily had to the interior for the purpose of inspection or repairs,

all as will be hereinafter set forth, and specically pointed out in the claims.

Figure l represents a side elevation of an air-box for a radiator embodying my invention and a portion of a radiator to which the same is applicable. Fig. 2 represents a vertical section on line as', Fig. 3, showing the air-box and its adj uncts in operative position. Fig. 3 representsa front elevation of Fig. 2. Fig. t represents asection on line x Fig. 2. Fig. 5 represents a section on line y y, Fig. 2.

Similar letters of reference indicate corresponding parts in the several iigures.

Referring to the drawings, A designates a portion of a wall, and B a passage or flue therethrough, the same extending downwardly in the present instance and terminating in a passage extending laterally into the interior of the apartment to be heated. g

C designates an air-box which consists of a casing having the upright portion or back D and the laterally-extending top and bottom flanges E and F, which are adapted to beinserted into a passage communicating with the iiue B.

G designates a member attached to the iiange F, said member being adapted to rest upon the floor H and thereby assist in sustaining the air-box in position, thelatter being also supported by means of auxiliary feet or posts under its front portion, if desired.

J designates an upwardly-extending member or portion Which is attached to the iiange E and is adapted to contact with the interior of the Wall in the present instance andto be sustained with respect thereto by means of the bolt K, the relative position of the latter being evident from Figs. l and 2,-tl1e said 4iiange or top E being provided with an outwardly-extending lip L, around which the incoming air is compelled to pass.

M designates a laterally-projecting lip or ledge in line with the fiange F, on which a damper or deiiector N is pivotally mounted. P designates journals for said damper N,which latter has a stem suitably attached thereto and passing through the slot R in a side T of the box A, said stem being engaged by the thumb-nut Q, whereby it will be evident that by the proper manipulation of said nut the damper or deflector can be adjusted to any desired position.

U designates a lug which forms part of the radiator-sections W and through which passes the bolt V, said bolt also passing through the sides T of the air-box and being held in position relative thereto by means of `a nut or other device.

X designates a shield or deflector which is mounted upon a ledge Y, which extends intermediate the sides T, it being, of course, apparent that a similar deiiector may be employed between the rear portions of the radiator-sections and the wall A, if desired.

Z designates inclined ways in the under portion of the air-box C, which latter has a beveled or inclined under surface, so that access can be readily had to points underneath the box for the purpose of sweeping, inspection, dac;

Al designates a sliding plate or gate which is movable in the ways Z, as will be evident from Fig. 2, whereby the passage A2 can be created in the under portion of the air-box, thus enabling air to pass to the interior of the latter, as indicated in Fig. 2. i

B designates a ledge which is. attached to the interior of each of the sides T, upon which ledges the legsV C of the radiatorare adapted to rest, said box thus serving a double function-namely, in providing means for the introduction and heating of fresh air from the exterior and in addition forming a cheap and serviceable support for the radiator.

. E designates a series of ports or passages through` the back D, the relative arrangement of which will be evident from Figs. 2

and 4, said passages being provided with the movable valves or gates D', which hang nor mally in a substantially vertical position and serve to control the ingress of air through the passages E', as will be understood from Fig. 2, the said gates or valves D' being sustained in any suitable manner relative to the ports E', which they control, and being composed of mica or other suitable material. The supporting means preferred by me, however, consist in providing each damper with journals F', which rotate in the lugs G', as indicated in Fig. 4, in which one of said gates only is shown, the others being omitted for the sake of clearness of illustration. It will, however, be apparent that other means may be employed for supporting the dampers, according to requirements.

The operation is as follows: The dampers D depend normally in a vertical position, as indicated in Fig. 2, and if the radiator be in operation the air around the same will be heated and by reason of the difference in speciiic gravity will rise and cause a suction or vacuum in the space within it and the airboX, thereby causing the dampers or valves D to move inwardly and admit air through the passages or ports E to the interior of the air-box and thence around the radiator and into the apartment to be heated, the air being also drawn into the air-box through the opening A2, while the flow of air can be entirely out off by turning the delector N upwardly into the position seen in dotted lines in Fig. 2, said deflector when closed preventing the incoming air from passing into the air-boX. It will be apparent that any other construction of deiiector may be employed, if desired, and that various changes may be made by those skilled in the art which will come within the scope of my invention, and I do not therefore desire to be limited in every instance to the exact construction I have herein shown and described.

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

1. An air-box for a radiator consisting of a suitable casing having openings in its rear wall and in its base, a sliding gate for controlling said opening in its base, a deflector mounted near the rear wall of said casing within the latter, a series of dampers supported upon the rear wall of said casing for controlling the openings therein and means for conducting air thereto, said deflector being between said sliding damper and said series of dampers.

2. An air-box for a radiator consisting of a casing, having an apertured back, top and bottom flanges projecting therefrom, an inclined bottom portion provided with a gate, sides attached to said back, having ledges thereon, dampers pivotally mounted adjacent said back and a movable deiiector located intermediate of said dampers and gate.

3.
