REGISTER FAN original Filed Marfcnfo; 1927 E7 lz 107 fl'la 32 122 :Agnggg rimmmmmm 31- l'snventor Patented Sept-` 6, 1932 JAMES L. WATERBURY, OF SPRINGFIELD, OHIO REGISTER FAN riginal application led March `The present invention relates toimprovements in register fans and is a division of my prior Patent No. 1,743,994, granted January 14, 1930.

5. A11/object of the invention is to provide an improved fan installation in combination with a register whereby hot air may be positively circulated through the room and in which a local circulation of air in the room may be effected.

Another object'of the invention is to provide a device of this character in which the grill is separate and distinct from the motor and fan installation enabling the grill to be removed independently of such installation; and in which the motor and fan installation are carried by a border frame which may be installed and removed as a unit either with or without the grill.

A further object of the invention resides in providing an improved register fan installation in which the motor controls are carried by the border frame and are removable with such border frame, the controls being exposed on the exterior of lthe border frame and on the outside of the grill for convenience in operation.

Withthe foregoing and other objects in view, the invention will vbe more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto.

In the drawing, wherein like symbols refer 5 'Referring more particularly to the draw- 30, 1927, Serial No.."179,704.` Divided and this tember 19, 1929. Serial No. 393,773.

`j ust how the to like or corresponding parts throughout the ing 31 designates a hot air stack built into application l'ed Septhe building, the floors of which are indicated at 32 and the walls at 33. `A register boxis indicated at 34 having a through Vpassage for the hot air and connecting at --its lower and upper ends with Vsections of the hot air stack In Figure 1, the lower section of the stack 31 is shown as formed with anl inwardly olfset shouldered neck 35 about which thebase of the register box 34 isV adapted to` fit. fAt its upper end the registerbox may, if desired, be provided with a similar inwardly offsetand shouldered neck 36 to receive and support the lower end of the upper adjacent section of the hot air stack 31. It is quite immaterial however, to the `present invention, connection of register boX and stack. is made.

The register boX is; in accordance with the usual practice, made with one or more outlets or openings to a room or rooms, and inthe presentV instance I have deemed it suifcient to illustrate the invention in connection with a single device for 4use in connection with one room only.

' Referring more particularly to Figure 3, the top portion of the border frame consists of the upper and lower spaced parallel walls 87'and 88. In like'` manner, the lower part of the border frame consists of upper and lower spaced parallel walls 89 and 90, the spacing being greater to form a large air chamber 91. The lower wall 90 may be held elevated by the small feet 92 and 93.

One side portion of theborder frame con-V- sists ofthe inner and outer spaced parallel walls 94 and 95. Between these walls are disposed four'webs 96, 97, 98 and 99, and in each of the spaced transverse webs is one or morev perforations 100, setting up communication between the compartments formed by these webs or division plates and forming also a through vertical passage between the side walls.

At the opposite side of the border frame are spaced inner and outer parallel walls 101 and 102, across which `arethe two perforated transverse webs 103 and 104, forming therebetween a compartment for holding the re# ceptacle or socket for a signal or other lamp 105 shown in Figure 2.

This lamp 105 is used as a signal to indicate when the motor is in operation and to prevent its being allowed to continue to operwall 89 of the lower portion ofthe border.` frame, and this boss is preferably tapered to' receive the socketed lower portion 107 of the hollow standard 108 which carries the electric motor 109 and fan 110.

The motor is preferably resiliently supported in the upper portion of the hollow standard 108 and space is left at the rear of the upper portion of the standard for a chamber 111 which communicates with the'interior of the motor.

Referring to Figures 2 and 3, there are provided lateral flanges 112 and 113 projecting inwardly of the border frame and adapted to receive the fastenings for holding the grill 114 removably in place.

Referring again to Figure 3, shoulders 115 and 116 are shown as provided upon the lower c and upper portions of the border frame, the

iii-turned lower and upper edges 117 `and 118 of the grill fitting against such shoulders. The grill plate may simply be mounted with a slip it in the border frame or be held therein in any desired manner.

A damper 119 is preferably carried pivotally bythe upper portion of the border frame just rearwardly of the shoulder 116, as shown in Figure l. The intermediate portion of the damper 119 is shaped to fit the particular 'v shape given to the upper portion of the hollow post 108 which supportsthe fan motor. The grill plate 114 is formed with a central outstanding portion 120, of a diameter slightly in excess of that of the fan 110, the fan being received within this outstanding portion which is provided with perforati'ons not only in its outer portions but also in its rim part.

Referring to Figure 1, a collar 121 having an angle iron cross section is fitted between the room wall 33 and the border frame 83 for closing the rear spaces inthe operating lower and side portions of the borderframe, the front spaces being enclosed between front walls of the border frame itself. As shown in Figure 2, the front lower portion of the border member is provided with slots 122 to admit air in the chamber 91, which communi- Cates, as shown in Figure 1, with the hollow boss 106, bywhich air has free access to the chamberv 111 and to the vmotor 109. As shown in Figure 1, there is also a shoulder 123 at the rear portion of the wall 89 to receive there-against the forward edge of the register box.

As shown in Figures 2 and 4, a switch box 124 is shown as being placed in the upper cornpartment between the webs 98 and 99 and an u operating handle 125 for the switch is shown on the exterior of the border frame. The lowermost compartment between the webs 96 and 97 is shown as occupied by a control box or resistor 126, having its control button 127 I ing plate for the outlet boxes in which the"` electrical devices 124 and 126 are mounted. These devices are accessible when the border frame and collar are separated, as by unscrewing the fastenings 129.

Now referring to Figure 5, the device isA` precisely as shown in Figure 4 except the within the plane of the front fiush plate 130 and there are additional walls 131 and 132 in the outlet boxes or electrical compartments for mounting the electrical devices and the control buttons 125 and 127.

The ymotor 109 is preferably held in the supporting device by means of interposed cushioning or resilient members 62, illusf tra-ted in Figures 1 and 2. In Figure 2 these rubber blocks or other cushioning elements 62 are shown as circumferentially separated to allow the circulation of air between the same.

In the operation of the device, hot air rises from a. furnace or other source up through the stack 31 and through the register box. When the damper 119 is completely closed, as shown in Figure 1, the hot air will ascend through the stack and through theregister box without being allowed to enter the room where the register fan is installed. However, through operation of the latch rod 66 the damper 119 may be pushedinwardly and swung about its upper pivotal support, whereby the lower free end will project across the stack an dv intercept the rising hot air, deflecting same out into the room and through the grill 114. This action will be induced by fthe operationof the fan 110, which is driven by the electric motor. The fan motor may be put into and out o-f operation by the switch button 125, and the speed of the motor and fan may be regulated by the resistor button During the operation of the fan, the fan blades 110 will not only draw in hot airfrom the stack 31 when the damper 119 is' open,

but the fan will also create a forced draft of air lthrough 'the hollow pedestal 108. This kcontrol buttons 125 and 123 are mounted 'ice l io

fan action draws in air through the slots 122 in the lower portion of the border frame, which air enters the chamber 91, ascends through the boss 106 and hollow pedestal 108 into the space 111 behind the electric motor 109; and thence the air is drawn through the electric motor, acting to cool the same and preventing motor overheating.

This air is quickly dispersed in the room by the action of the fan. The cooling air from chamber 111 also passes about the electric motor 109 between the rubber blocks 62. This air will serve to shield and protect the electric motor from the stack heat.

It is obvious that Various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims.

What is claimed is 1. In combination with a hot air stack V and a register box, a border frame for the register box having a cold air channel therein, a grill plate fitted in said border frame, a fan and motor unit in said frame, hollow means for supporting said unit and being interiorly in communication with the air chamber in said border frame, and a damper associated with said grill plate.
