C. SHIrP, a

be controlled, second, inside air circulation must be posslble when desired, and, third, that outside air can be admitted to the radiator when desired. The above requirements necessitate an apparatus whereby inside air circulation can be alternately established with that of securing air from the outside of the building, or that the two may be operated simultaneously in such relative degrees to produce the best results in the condition of the air within the building, in

respective of the temperature of the air outside the building. To meet the above requirements radiator casings heretofore have had communication atthe rear with air ducts leading to the outside the building and on their front sides and near the floor these casings, were provided-with inlet orifices through which inside air circulation could be established. The openings through the air inlet ducts leading to the outside of the building and the orifices in the front sides of the casing were controlled by sepa rate dampers, these dampers in many cases being actuated by a single lever, while the readily discernible position of the front dampers also indicated the relative position of the rear dampers. The objections to placing the inlet orifices in front of the casings and near the floor was, first,-in case of schOol buildings the insertion of foreign matter into the orifices by the children, and, second, the low position of the orifices permitted the infiowing air currents to carry the dust from the floor and deposit same upon the Walls immediately above the radiator casings.

To overcome these previously mentioned objections it has been found expedient to remove the an intake orifices from the front sides of the casings and place them in the back sides of the casings and sutficiently above the floor, so that, with the introduction of intervening aprons between the orifices and floor, the ingoing air in gaining access to the interior of the casings is forced to enter from above and at thesides of the easings and thus carry along only such dust as may be held in suspension. Placing both.

orifices andtheir controlling dampers in the back sldes of the casings, however, necessitated the introduction of certain means for not only actuating said dampers but to disclose at all times their relative position.

The present invention relates to certain mechanism whereby both dampers maybe slmultaneously actuated and their respective positions indicated; and the object of the invention consists in the provision of certain means for accomplishing the above result'which is simple in construction, efiicient in operation, whereby the dampers may be.-

simultaneousl actuated and their positions indicated to the operator from the front of the radiator casing.

I accomplish the above object of the invention, and such others as may appear from.

a perusal of the specification and claims, by means of the construction illustrated in the accompanying drawings, forming a part hereof, in wh1ch- I,

Figure 1 is a fragmentary detail vertical sectional view through a section of a building. wall, radiator casing and air inlet orifices. Fig. 2 is a fragmentary detail vertical sectional view, on the line 2-2 in Fig. 1, in which the radiator is omitted. Fig. 3 is an enlarged view in side elevation of the connection between the vertical indicator rod and guide-plate. Fig. 4 is a front elevation of the construction shown in Fig. 3. Fig. 5 is a top or plan view of the construction shown in Fig. 4, the indicator rod being shown in section,

Referring to the drawings, 10 represents the usual and well known radiator, and 11 the inclosing casing which is formed of sheet metal. On the back side of the casing and near the floor the casing communicates with a wall air inlet ventilating duct 12, the latter being let into the brick-work or such other material from which the'wall 13 is constructed. The orifice between the casing and duct may be increased or reduced 1n size by means of a damper which is pivoted 16 to the wall of duct 12. Damper 15 is actuated through the medium or a shifting rod 17 and link 18, the rod extend- 5 ing forward and through a slot 19 in the "front wall of the radiator casing base 20 and is provided with the notches 21 adapted to engage the wall of base 20 so that the damper can be partially or entirely moved to the limit of its travel. Air entering through duct 12 from the outside the building is discharged into casing 11 and after passing vertically between the heated coils of the radiator is discharged into the room through the open top of said casing. Casing 11 is provided in the back wall with an orifice 25 through which inside air circulation can be established when desired. Orilice 25 is usually closed, by means of a damper 26, when air duct 12 is entirely open, but the two openings may be partially open at the same time, in order to secure proper atmospheric condition within the room by means of the adjustments secured with notches 21, as heretofore described. Since the movement of damper 26 is in a direction at right angles to the general movement of rod 17, certain mechanism is interposed to not only synchronize the movements of dampers 15 and 26 but to control the distance of travel of damper 28. To accomplish this result damper 26 is shifted through the medium or a vertically disposed rod 28 carrying a transverse pin 29 in which the ends of said pin rest within slots 30 in yoke 31.

Yoke 33. is also provided with a vertical slot 32 adapted to receive rod 28, the extended portions of yoke 81 serving to arrest lateral. movement or said rod. Yoke 3l'is secured to damoer 26, and since the metal comprising both the damper and walls of the casing is composed or thin material these parts are apt to warp and draw away from red 28, in which case slots 30 allow for such movement without causing impingement upon said rod to interfere with its normal movement. Damper 28 is moved by means of transverse pin 29 engaging the extended portions of yolre 31. See Figs. 3, eland 5.. Operative connection is provided between shifting rod 17 and vertical rod 28 through the medium of a chain 35, one end or the latter being secured at a convenient point on the rod 17 trom whence the chain passes over sheave 36, thence upward and over sheave 37 and thence downward and attaching to the lower end of vertical rod 28, the initial arrangement and connections of chain 85 being such when damper 15 stands so as to entirely close the opening through duct 12, damper 28, stands so as to leave orifice as "fully open, and vice versa. Rod 28 is provided with an extension member 28 which extends up and slightly above the upper edge of casing and the upper end or member 28 can ries an indicator plate 38 whose purpose will be hereinafter described. Rod 28 and its member 28 may be lengthened or shortened through the medium of a sleeve l0 and setscrew ll in order to accommodate the rod to casings of different heights. Having the above construction in mind, with the several parts occupying the positions shown in Fig. 1, when shifting rod 17 is moved in the direction indicated by the arrow to open damper 15 chain 35 is carried along, and chain 35, operating over sheaves 36 and 37, moves rod 28' a suflicient distance vertically to cause damper 26 to close orifice 25, and in reversing the movement of rod 17 the movements of the associated parts are reversed.

- Sheaves 36 and 37 are mounted in a bracket 89 secured to the rear wall of casing 11.

As before stated, member 28 carries the movable indicator plate 38 which is brought into full view at the upper limit of its travel, and at the lower limit of travel said-plate is hidden by means of the faceplate of the stationary indicator plate 46 secured to the rear wall. oi? casing 11 by means of the bolts l7. The stationary indicator plate is usually supplied with the word shut and is normally exposed for the reason that damper l5 normally stands to close the opening through duct 12, and damper 26 stands to fully expose orifice 25, which permits unobstructed inside air circulation within the room. Movable indicator plate 88 is supplied with the word open, and when said plate is elevated to bring the word open into view plate 38 will so cover plate as to obscure the word shut. l/Vhen plate 38 is elevated to expose the word open it indicates that damper 15 is moved to open pas. sageway through duct 12 and that damper 26 is moved to close orifice 25.

Having thus fully described my said invention, what l desire to secure by Letters Patent, is

1. The combination, with a steam. radiator casing provided in its back wall with an air inlet opening leading to the outside of the building and a second opening communicating with the interior oi the room, a damper -Ior controlling the movement of air through each opening, a push-rod for actuating the damper in the outlet opening for the outside air, a rod for mounting the damper for controlling'the opening for the inside air, a chain for connecting the two rods together, a sheave for engaging the chain and for changing the direction or travel of one rod to that of the other, and an indicator moving with said dampers, -for indicating the posihd "*h d' t" tion or eac amper wit its a acen ll'LBb opening.

2. The combination, wrth a steam radiator casing provided in its rear wall with an arr inlet opening communicating with the interror or the room, a sliding damper for connection between the mamas a controlling the passage of air through said opening, a yoke carried by said'damper, a

movable rod, means carried by said rod for engaging said yoke to actuate said sliding damper, a damper actuating rod, a flexible damper actuating rod and movable rod, and an indicator moving with said damper for indicating the position of the latter with said inlet opening.

In witness whereof I have hereunto'set my 1 hand and seal at Indianapolis, Indiana, this 17th day of October, A. D. one thousand nine hundred and sixteen.
