HOT-AIR REGISTER.

Specification of Letters Patent No. 9,664, dated April 12, 1853.

To all whom t may concern 'Be it known that I, EDWARD A. TUTTLE, of the city of l/Villiamsburg, county of Kings, and State of New York, have invented a new and useful Improvement on Hot-Air Registers and Ventilatore; and I hereby do declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, forming a part of this specification, in which- Figure l is an edge view of a leaf of the register and ventilator. Fig. 2 is a plan View o-f a bell crank and chain for operating the leaves. Fig. 3 is an edge view of Fig. 2. Fig. l is a plan view of the register and ventilator with the leaves open.

The same letters of reference indicate like parts.

The nature of my invention consists in constructing the leaves of a ventilator and register, with projections on their surfaces, to form an ornamental fret work between the leaves or slats, when they are turned with their edges uppermost or partially so, for the purpose of dispensing entirely with the open ornamental top plate which is now employed on air registers and ventilators to hide the rough brick work or back ground, behind the ventilator and register.

The nature of my invention further coni sists in operating the leaves, by attaching a chain to the part of the projection of each, thus uniting them altogether and I attach the ends of said chain to a bell crank one on each side of the register, by which, when one of the bell cranks is operated, by means of chain or other handle, the leaves are opened', and when the other bell crank is operated in a similar manner, the leaves of the register are closed.

To enable others skilled in the art, to make and use my invention I will proceed to describe it.

I construct my register or ventilator of any known or desirable shape. The leaves of registers or ventilators as now made, have flat or smooth surfaces, they have no projections to hide the back ground. Consequently to accomplish this object they are made (each one) with a. top, separate plate, of open metal work. I dispense with this top plate and accomplish the same object,

by constructing the leaves of my register as represented by Fig. l, (a single leaf of my register). It is cast with ornamental open projections of any suitable and desirable form. These projections are cast on or near the middle of each leaf, and extend longitudinally from end to end. The object o-f these projections is exhibited in Fig. 4; the leaves in said figure are thrown open. In other words their edges are presented, to show the projections a b, filling up the spaces between the leaves in such manner vas to obscure the back ground, and yet leave open spaces between the projections and in the projections, to allow the air to pass through, and the view being unobscured by a front plate, of fret work the amount of air passing through, may be more easily ascertained, and regulated. These leaves are set in the register frame in any of the usual modes, to allow of them being easily turned. I operate them, to open and close them, by bell cranks and a chain or chains.

B is the frame of the register.

c c are the bell cranks and C the chain. The leaves have knobs on one end to which the chain C is attached, this unites them together and to open them the bell crank c" is operated by the chain d, to shut them the bell crank c is operated by the chain CZ. The benefits derived from thus operating the leaves, consists in the economy and simplicity of the devices as combined with the register, in comparison with the more cumbrous and expensive devices, now employed to effect the same object.

The leaves may be made so as to be placed at a greater distance apart in the frame, and thus the register may be made with a less number of leaves.

The projections can be cast on the leaves, to allow of a great number of very small spaces between each pair, to prevent articles falling through, when the register is placed on a floor. The projections on the leaves, render them stronger, and as the top plate, now employed which has been heretofore described is dispensed with, my register and ventilator, can be manufactured at less cost; consequently for Ventilating purposes, so conducive to health, it will enable more people to employ such apparatus in their dwellings.

What I claim as new and desire to secure the separate, front or top plate, of ornaby Letters Patent, ismental open Work, novv employed on regis- 10 Constructing the leaves (of a register or ters and ventilators. ventilator) With projections on their sur- EDWARD A TUTTLE 5 faces, to form an ornamental open or fret Work between the leaves when they are Vitnesses: turned with their edges uppermost or par- C.
