BASEBOARD RADIATORS Filed Aug. 22, 1952 2 Sheets-Sheet 2 2,731,903 BASEBOARD RADIATORS Application August 22, 1952, Serial No. 305,864 11 Claims. (Cl. 98-40) The invention relates to baseboard radiators and more particularly to control devices for the dampers in the baseboard.

One object of the invention is to provide an improved damper for a baseboard radiator which is adapted to effectively close the damper to cut off heat from the radiator when the baseboard is installed along an uneven wall.

Another object is to provide a damper control device which consists of pre-assembled elements and can be easily installed at different points along the baseboard.

Another object is to provide a damper control device which is simple in construction, eflicient in operation and can be economically produced.

Another object is to provide a damper control device in a baseboard which is manually operated and avoids the use of closure springs.

Other objects will appear from the detailed description.

The invention consists in the several novel features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

The invention is exemplified in a baseboard radiator with a sheet metal housing including a back section 12 with a forwardly extending top wall 13 having a bead 14 at its front edge, partitions 15 secured to the back section and provided with open ended recesses 16, a pre-assembled radiator including tubes 17 for the circulation of heat ing fluid and fin plates 18 for heat transfer, a front section 19 having an inset ledge 20 overlying and adapted to seat on the upper front corners of the partitions 15, and an upstanding flange 21 along its bottom adapted to hook into notches 22 in said partitions whereby the front plate will be supported to enclose the radiator. The lower end of the front section 19 is spaced from the floor and forwardly of the back section to provide an opening for admitting air to the duct or flue between the front section 19 and the rear section 12 in which the radiator is located. The upper portion of the front section 19 between ledge 20 and the bead 14 on top 13 is provided with a vertical of a baseboard radiator thereto, the damper being series of horizontal rows of slots 21 for theoutflow of v United States Patent 0 too , tion 19 has a backwardly extending top flange 22-which terminates in a depending flange 23 which is provided with a forwardly extending ledge 24. The

flanges

22 and 23 and ledge 24 form a forwardly facing channel for pivotally supporting a damper 26 which extends longitudinally of the baseboard. The damper is formed of sheet metal, has a downwardly bent flange 27, the lower edge of which is movably seated on the ledge 24 for the movement of the damper between open and closed positions. The lower end of the damper 26 is provided with an upturned flange 28 which is flat over a sufiicient area to seat on a suflicient area of the inner face of the lower portion of the front section 19 to close at least one horizontal series of slots 21 cutting off the outflow of air from the housing. The flange 28 is resilient so it can be pressed tightly against the front plate to eflt'ect a tight closure. The lower edge of flange 27 is free to slide and pivot on ledge 24 to permit damper 26 to be flexed to conform to any uneveness in the front section, and to permit the damper to be pressed forwardly until flange 28 is seated on the front section throughout the length of the radiator. It will be understood that these radiators are of considerable length, for example, 10 feet, and when installed at the base of a building wall are sometimes deformed according to irregularities in the wall. In consequence, it is important to provide a damper which will close the slots 21 notwithstanding these irregularities.

section 19 to loosely locate the mounting plate 31' on and engage screw-threaded holes 39 in the back plate 33. The inner tapered ends of screws 38 are adapted to abut against the lower edge of and between longitudinal rows of slots 21 and lock the hooks 36 on said webs for locking the mounting plate 31 for the damper controlling device in different places along the front section of the baseboard, as shown in Fig. 4.

A knob 40 or operating element is fixed to a stem or shaft 41, which is rotatably mounted in and extends through the mounting plate 31 and back plate 33. Spring washers 41 in a groove on shaft 41 hold the shaft 41 inner end of stem 41 and is manually rotatable by the knob 40. A shifter 44 for the damper 26 is formed of a strip of round wire and a pintle 45 which is confined to swing on a substantially vertical axis in a socket 46 which is formed between an outwardly indented portion 47 in the mounting plate 31 and the front face of back plate 33. The shifter includes a member 48 which extends from the upper end of pintle 45 through a substantially horizontal slot 49 in back plate 33 and is adapted to swing in a substantially horizontal arc,

The damper is not attached to the front plate but is pivotally and bodily lower end of arm 50 which swings formed on the body of the damper 26 by flange 28, for swinging the damper transversely of the housing by the toward and away from the front section '19 on the vertical. axisv of pintle 45., V

. and9, the lower end. of;arm 5.0 which swings horizontally on the verticalaxisof'pintle 45, and is inclined down Wardly, and laterally, willswing in the channel between flange-28 and the back of damper 26 and resiliently force the flange of the damper against the back face or" front section, 19 and close the-lowest row of slots 21' to prevent 7 air from passing between the damper and the front plate 19. Inthis operationof the damper, there is some resiliencein the armStl so the flange 23 can be tightly pressed against the section 19 around slots 21 and the flange 27 on which the damper is supported can pivot and slide on When the arm 59 of the shifter 44 V theledge. 24. This makes. it possible for the damper to flex to fit the back face of section 1? when there is uneven; ness in the sections of the baseboard. V

In assembling'the control device with the housing and damper, the pivot flange 27' is set on ledge 24 before the front and back sections 12 and 18 are assembled. The front section 19 and rear section of the baseboard are then assembled by inserting the flange 27 on the front section 19 into the notches 22 in the partitions 15 andplacing the ledge 26 of front section over the upper front corners of partitions 15 and the top flange 22' of the fronfsection 19 under the top wall 13. 'The damper control device is preassembled so it can be installed at any selected place or places along the baseboard. in installing the control device, the knob 40 is turned to about half'open position and the wire arm 50 is inserted through a slot 21 in the second row of the-top'of section 19 and into the channel in the damper. Tongues 35 are inserted through a pair of the second row of slots from the top to position the mounting plate 31 horizontally on the front section 19. Plate 31 is then pressed downwardly to engage hooks 36 and the upper edges of webs between the slots in the second and third rowof slots 21 from the top. Set.

screws 38 are tightened to lock the hooks 36 to the front section 19. The control device will then operate to open and close the damper by rotation of the knob 40 in oppositedirections to selectively open or close. the damper.

In Fig. 10, the damper control device is shown as used in a baseboard of a different construction. This com prises a sheet metal back section 63 and a sheet metal front section 61 provided with a top wall 62.v The back action has a forwardly extending ledge 63 which forms a seat for a forwardly'extending flange 64 on the front section which is spaced below top wall 62. Resilient strips 65 hold the top of section 61 on the ledge 63. In this construction, sheet metal brackets 66 are secured to the back section 60; engagethe top wall 62 provided with notches 68 in which the flange 27 of the damper 26 is seated. The control device is the same as hereinbefore described and is assembled with the front section in the same manner, it'being understoodthat the front section 61 is provided with slots described. In this modification, the lower edge of flange 27 on the damper is pivotally and slidably movable'on the bottom of notches 68 in the brackets 66.

The invention exemplifies a damper and a damper controldevice which consists of preassembled elements difierent places along the baseboard; also a damper and at 67 and are 21 as previously baseboard radiator with a which can be readily installed at control,,device which .are, adapted tov operate, efliciently when the baseboard is'uneven when installed; also a'control device which is simple in construction and can be economically reproduced; and also a control device which dispenses with closure springs.
