FAN FOR FURNACE HOT AIR PIPES Filed D80. 12, 1930 v INVENTOR:

W11 55:- fiJVQLL-SZCZTJZJ gel-w BY limb WA flay A TTORNEYQ' Patented Nov. 8, 1932 ALVA L. SEARLES, OF GRAND RAPIDS, MICHIGAN FAN FOR FURNACE HOT AIR PIPES Application filed December 12, 1930. Serial No. 501,798.

The present invention relates to air driving fans for the pipes of air heating furnaces; and its object is, generally, to provide such a fan removably mounted in the discharge vent of a hot air pipe; and more particularly, to provide such a fan and its propelling motor mounted on and inside the grid extending across such vent; and further, to provide improved features of the construction and mounting of such a fanand motor.

This, and any other and more specific objects hereinafter appearing are attained by, and the invention finds preferable embodiment in, the structure particularly described in the body of this specification, and illustrated by the accompanying drawing, in which:

' Figure 1 is an inner side view of agrid extending across the discharge vent of a furnace hot air pipe, the surrounding mounting member for the grid, and an electric motor and fan carried by the grid;

Figure 2 is a vertical sectional view thereof taken on line 22 of Figure 1; and

Figure 3 is a side view of the same and a central vertical sectional view of the furnace air pipe.

In the drawing the hot air pipe 1 extends upwardly from a furnace (not shown) through a floor 2, and has a portion 3 extending horizontally through the wall 4 to the discharge vent 5. This vent has a rectangular surrounding member 6 secured to said wall and provided with slots or keepers 7 and 8 in its lower and upper portions 9, 10

respectively. I

The grid 11 extending across said discharge vent has at its lower edge tongues, '12 extending removably through the keepers rand ad:

1 jacent its upper edge buttons 13 having handles 14 and cross barszl5' insertable through the keepers 8, these buttons being turnable to,

-a position wherein the cross bars 15engage the inner side of member 6 to releasably se- 5 cure the grid in the position shown in said views. A metal strap 16 is mounted atits u per and lower ends respectively, as by bolts ll, 18, to the inner side of the grid, such points 17, 18 of mounting being at the opposite sides of said vent. An electric motor indicated at 20 having current-supplying wires 21 extending through anopening 22 in the grid, and a shaft 23 extending in a direction transverse to the grid and carrying a fan or blower 24, is mounted as by bolts 25 on the strap 16 and between the same and the grid as particularly well seen in Figure 2.

, A series of vanes 26 extending across the pipes vent and mounted at their ends 27 ori the grid are connected by a bar 28 and are turnable together thereby to different airdefiecting positions.

It will be seen that the weight of the motor and fan, which are mounted on the inner side of the substantially vertical grid, tilts the grid about the slot keepers 7 in which the tongues 12 arereceived to the position seen in Figure 2" and maintains the same in that position although the buttons 13 may be dispensed with. p

The invention being intended to be pointed out in the claims, is not to be limited to or by details of construction of the particular embodiment thereof illustrated by the drawing or-hereinbefore described. I

I claim:

1. In combination with an air pipe having a discharge vent with a surrounding member having keepers at opposite sides respectively of said vent; a removable grid having a tongue removably extending into the keeper on one of said sides of the surrounding memher, and a button removably engaging in a keeper on the other side of said member and turnable to a position securing the grid to said member and reversely to a position releasing the grid, the grid having a strap mounted at its ends on the inner side of the grid at the opposite sides respectively of said vent; an electric motor havln a shaft axially transverse to the grid; a an carried by said shaft, the motor and fan being mounted on the strap between the same and the grid; air-deflecting vanes turnably mounted at their ends on the grid between the same and the motor and having means for turning the vanes together to difierent air-deflecting positions.

' 2. In combination with a vertically extending air pipe having a; horizontal-1y extending portion with a discharge vent pro vided withv keepers at itsupper and lower sides; aremovable grid having a.- tongue removably seated in thekeeper at said lower side and a. button removably engaging the keeper at said; upper side,.the-gri'dlhaving in-- ward'ly extending upper and lower wing portions inclined toward each other and con:- nected by vertically extending laterally spaced members, the grid having alsoa strap secured at its ends on said wing-portions re-- spectively'; an electric motor having a shaft extending transversely of the grid-:: 2; fan carried by said: shaft, the motor and fan being mounted? on the strap between the same and the hereinafter-mentioned vanes; air-deflecting vanes turnably mounted at their ends on said vertically extending laterally spaced members, the vanes having means extending through the grid for turning the vanes together todifferent air-deflecting. positions.

In testimony whereof I have hereunto set my hand at Grand Rapids, Michigan, this 9th day of December,v1930;

ALVA L. SEARLES.
