Ventilating Register.

JOSEPH LEEDS, OF PHILADELPHIA, PENNSYLVANIA.

VENTILATING-RE GISTEE.

Specification of Letters Patent No.

To all whom it may concern:

Be it known that I, JosnPI-I LEEDS, of the city and county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Registers; and I do hereby declare the following to be a full, clear, and exactdescription of the same, reference being had to the accompanying drawings, making a part thereof, in which- Figure 1, represents a longitudinal vertical section through the register, and Fig. 2, represents a top view of the register. Similar letters in the two figures denote like parts.

The nature of my invention consists in arranging the swing valve of a register which is common to two passages, in such a manner as to introduce hot air into an apartment through said register, or, entirely, or partially close it against such ingress. Or, to cause it to act as a ventilator to said apartment by closing it against ingress, and opening it for the egress of air, thus making it both a register and a ventilator at pleasure.

To enable others skilled in the art to make and use my invent-ion, I w`ll proceed to describe the same with reference to the drawings.

A represents a swing valve having its fulcrum at B, in the arm O, which is attached to the valve A, is a slot D ,in which a pin on the end of rod E slides freely as seen in F 2, and the rod E slides in a slot G, in the top of the register, and is held from falling down by its head H, whenever the valve is to be moved, the head H, is shoved in a horizontal direction which moves the rod E in the same direction; this oscillates the arm O, and valve A on their fulcrum B.

The fulcrum or pivot B, is at the center of the Vvalve A, and at or near the inner line of the flue or passage leading from hi to N, which passage may serve for Conducting heated air from a furnace to an apartment, or for taking foul, or heated air, from the apartment to the flue or passage through which it may escape, thus serving the purpose of a register, and a ventilator. Or the valve may be so turned as to let a portion of hot air into, or take out a portion of vitiated air from, the apartment, or entirely cut off the apartment from the flue--as folloWs: Suppose an ascending current of hot, A

or cold air to be passing in a line from N to M, and the valve A, to be in the position shown in black lines in Fig. 1, the Whole current would be turned through the register and into the apartment. Now reverse the valve A, by turning it as far as it will go, in the opposite direction, and it closes the ingress current, and opens a passage for the egress of the air from the apartment into the flue or passage, whence it can escape. By turning the valve A, as shown by the red lines Fig. 1, the greater portion of the current passes up the fiue while a lesser current is also drawn from the apartment into the flue also. By turning the valve (as shown in red) slightly in an opposite direction, it would allow a portion of the ascending current to enter the room, and the balance of the column or volume to go up the passage. Again, turn the valve parallel with the walls of the flue, and the apartment is cut off entirely from the flue passage, and neither receives from, nor gives to it,-any of its heated or vitiated air. Thus this register, or rather its valve may regulate the quantity of air that passes up the flue from N to M, or the quantity that may pass into an apartment, or the quantity that may pass out of said apartment, at pleasure, making a perfect register and ventilator as occasion may require.

The front part of the register slips over that part of it thatl sets in the wall, so that the passage from N to M may be made to conform to any .tlue passage already built, and which may have more or less thickness of wall around it-or in other words lengthening or shortening the register case to suit flues already built.

Having thus fully described the nature of my invention what I claim therein as new and desire to secure by Letters Patent is-- In combination with a register the hanging of the Valve A, by its center, as shown, so as to make said valve a regulator or cutoif, to the ascending current of air, from N to M, and at the same time a regulator of the ingress, or the egress of air to or from an apartment and thus causing a register to serve the purpose of a ventilator, as herein described.
