REGULATING DEVlCE FOR THE DISTRIBUTlNG-PIPES 0F HOT-AIR FURNACES.

SPECIFICATION forming part of Letters Patent No. 414,349, dated November 5, 1889.

Application filed December 31, 1888. Serial No. 295,069. (No model.) Patented in Canada February 14, 1889, No. 30,787.

To all whom, it may concern.-

Be it known that I, THOMAS GRAHAM WAN- LESS, of the city of Toronto, in the count-y of York, in the Province of Ontario, Canada, have invented a certain new and Improved Regulating Device for the Distributing-Pipes of Hot-Air Furnaces, (for which I have obtained a patent in Canada, No. 30,787, dated February 14, 1889,) of which the following is a specification.

'The object of the invention is to design a simple device by which the hot air may be entirely cut off from any one of the distribut ing-pipes; and it consists in the peculiar conibinations and construction and arrangement of parts, all as more fully hereinafter described and claimed.

The drawing represents a perspective sectional View of a hot-air registerin the floor of a room and of a distributing-pipe leading from the said register to the hot-air chamber of a furnace, a valve arranged in accordance with my invention being located in the said distributing-pipe.

In the drawing, A represents the hot-airdistributing pipe, and B the hot-air chamber of a furnace from which the said distributing-pipe extends.

O is the register with which the distributing-pipe A connects.

D is a valve located in the distributingpipe A in proximity to the hot-air chamber B. This valve is arranged so that it may close the said distributing-pipe in proximity to the hot-air chamber B, and thus completely cut off all hot air from the said distributing-pipe. A cord or chain E is connected to the valve D at one end, and after passing around suitranged within the distributing-pipe A and the valve D weighted, so that it will close when not pulled upon by the cord or chain E, the opposite end being connected to a lever Gr, pivoted on the bottom of the perforated plate of the register O. A button g, projecting through a curved slot in the said perforated plate, enables the lever G to be turned on its pivot, and thus either open the valve or permit it to close itself.

\Vhat I claim as my invention is 1. The combination, with the hot-airchamher, the distributing-pipe, and the register, of the pivoted valve within said pipe inproX- imity to the hot-air chamber, the lever pivoted within the register, and the cord or chain connecting said lever with the valve, substantially as shown and described.

2. The combination, with the hot-airchamher, the distributing-pipe, and the register, of the weighted pivoted valve within said pipe in proximity to the hot-air chamber, the lever pivoted within the register, and the cord orchain arranged within said pipe and connecting said lever with the valve, substantially as shown and described.

3. The combination, with the hot-air chamher, the distributing-pipe, and the register, of the valve within said pipe in proximity to the said chamber, the horizontal lever pivoted to the plate O of the register, the cord connecting one end of said lever with the valve and arranged within the pipe, and the other end of the lever provided with a button working in a slot in the register, substantially as shown and described.

Toronto, December 22, 1888.
