Application filed. May 3, 1921.

To all whom it'may concern Be it known that I, JArrns A. TARTE, a citizen of, the United States, residing at Blaine, inthe county of 'VVhatcom and State of Washington, have invented a new and useful Deflecting Damper for Pipeless Furnaces, of which the following is a specification.

My invention relates to deflecting dampers for pipeless, hot-air furnaces, and the objects of my invention are: first, to provide deflectors for dividing and deflecting the ascending column of air as it leaves the furnace; second, to adapt said deflectors for control and closure purposes; and third, to cause said dampers to operate by-pass dampers for controlling by-pass, hot-air outlets.

I attain these objects with the mechanism illustrated in the accompanying sheet of drawings in which Figure 1 is a plan view of the top of the cold-air inlet and hot-air outlet of a pipeless, hot-air furnace, and Fig. 2 is a side elevation of Fig. 1 in section on a vertical, medial plane.

Similar characters refer to similar parts throughout. Certain parts are broken away to disclose those hidden thereby.

More particularly: 3 is the casing of the upper part of the cold-air inlet flue. & is a grill covering the same. 5 is the casing of the upper part of the hot-air outlet flue. The remainder of the pipeless furnace of which the illustrations show a part is broken away as not essential to the proper under standing of this invention.

6 is an annular damper seat fastened to the interior of easing 5.

7 is one leaf of a bifold damper hinged on pin 10.

8 is a by-pass damper rigidly'fastened to leaf 7 by arm 9.

10 is a hinge pin mounted in casing 5 located to adapt leaves 7 and 11 for closure on seat 6.

11 is the other leaf of said bifold damper.

12 is a by-pass damper rigidly fastened to leaf 11 by arm 13.

14, 14 is a chain or cable one end of which has two branches, each of which is fastened to one of leaves 7 and 11, and both are riven over sheave 15 from which the cable passes through a hole in casing 3 and to a con venient point from which to control said damper where it is adjustably fastened.

15 is a sheave fastened to the under side of grill 4.

Specification of Letters Patent.

Serial No. 466,583.-

16 is a lug on leaf 11 to bear against leaf leaves are normally open, and, in coopera-- tion with bifurcated chain 14, prevents either of said damper leaves from attaining a vertical position.

17 is a hot-air, by-pass, outlet pipe leaving flue 5 beneath damper 7, 11.

18 is a hot-air, by-pass, outlet pipe leaving flue 5 beneath damper 7, 11.

The inner end of pipe 17 is adapted for closure by damper 8 when leaf 7 is normally open, and pipe 18 is adapted for closure by damper 12 when leaf 11 is normally open. Pipes 17 and 18 may find an outlet in the furnace room, out of doors, or in distant chambers as preferred.

In operation: The positions of the various parts of my device shown in full lines in the drawings are those of normal operation when heating a house, leaves 7 and 11 beingnormally open and dampers 8 and 12 closing pipes 17 and 18. All of the hot air from the furnace now passes through grill 4:. But it is divided and deflected into two streams by normally open yet inclined- damper leaves 7 and 11. It is customary to locate furnaces of this type in the door opening between chambers. Not inlfrequently the hot air rising therefrom blisters, and otherwise injures the casing of said door opening. This undesirable result is prevented by my device as shown.

On releasing cable 14, from its outer-end fastening, not shown, damper leaves 7 and 11 drop by their own weight to their dottedline positons at 7 and 11 on seat 6. Simultaneously dampers 8 and 12 pass to their dotted-line positions at 8 and 12 respectively, fully uncovering pipes 17 and 18, and all of the hot air from said furnace must pass out through by- pass pipes 17 and 18.

It is easily apparent that leaves 7 and 11 may be retained by cable 14 in a partly open position and the hot air divided between said by-pass pipes and the main flue through grill 4-.

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

1. In a pipeless, hot-air furnace in combination, a hot-air, outlet flue; a bifold, deflector damper hingably mounted in said flue near its outer end and adapted to divide the passing stream of hot air and deflect the same, and further adapted to close said hot- Patented June 6, 1922 air outlet flue; a by-pass, hot-air outlet pipe leaving;- said hot-air flue below said deflecting damper, and means operable by said defleeting damper adapted to keep closed the same, and further adapted to close said hot air, outlet flue, two bypass, hot-air, outlet pipes leaving said hot-air flue below said de- Hector damper, a damper fastened to each of the leaves of said bifold damper and adapted to close said by-pass, outlet pipes when the leaves of said bifold damper are fully opened and further adapted to open said by-pass pipes when said bifold dam per is closed, and means to operate the leaves of said bifold damper.
