IMPROVEMENT lN- HOT-AIR REGISTERS.

Specification forming part of Letters Patent No. 6,060, dated. January 23, 1849; Reissue N0. 1'36, dated May 1, 1849.

To all whom it may concern.-

Be it known that 1, CHARLES E. TUTTLE, of Williamsburg, county of Kings, and State of New York,have invented a new and Improved Register, used for the purpose of regulating the admission of heated air into rooms or dwellings from hot-airfurnaces or other warming apparatus, or for ventilating rooms and dwellings; and I do declare the following to be a full and exact description.

Thenature of my invention consists in the new and improved method adopted of opening and closing the register or ventilator by means-of an upright or vertical wheel, or a segment of a wheel, which is connected with and gives motion to the valves by means of a movable connecting-rod, which is suspended on the side of the wheel on a pin projecting'therefrom; and this connecting-rod is attached to the valves by pins at their ends.

In order to enable others skilled in the art to make and use myinvention, I will proceed, in aid of the accompanying drawings, to describe its construction and operation.

I construct my register of metals, as others usually are, and in the usual forms. The top or surface is made open by scroll or fret work, so as to admit the passage of warm air freely, and at the same time to protect the valves, as in case of a person walking over the register, if placed in the floor.

My drawings and description describe my register when constructed in a square form. The valves b b b, Fig. 1, three in number, (sometimes a greater orless number are used,) are suspended in the frame of the register at a sufficient depth or distance from its top or scroll-work, so that when they are open the fans or valves will not come in contact with the top of the register. The pins or axles cc 0, upon which the valves are suspended and upon which they should turn freely, are situated at the ends of the valves, at or near their mid- One end of the valves is secured in the dle. frame by the pins 0 c 0, playing in the holes d d d (see Fig. 2) in the frame. The opposite ends of the valves are secured by the strip ee, which is secured firmly and closely over the ends of the pins 0 c c by a screw at f. At the end of the register, and playing freely upon its center, is the wheel G, attached to the register by the means of a screw or pin, h. (See Fig. 2.) This screw or pin isfirmly fixed j in the frame and forms the axle of the wheel.

The wheel is preserved on its axle by ahead on this pin or axle, which head must be flush with the surface of the wheel. Upon the wheel, situated at a distance from its center, isthe pin 2', Fig. 2. This pin must be placed horizontally with the center of the wheel when the register is closed. Upon this pint is suspended the connecting-rod jj, shaped nearly as in the drawing Fig. 2, or in any convenient manner, and moving freely upon its axle i. This connecting-rod rises or falls in a circular direction when the wheel is put in motion. This connecting-rod is attached to the valves at m m m by pins on the ends of the valves. These pins are situated at the same distance from the centers of the axles at d d d, Fig. 2, that the pin i is from the center h. This is necessary in order that the register may work without binding at any stage of its opening or closing. Now, it will be perceived that when the wheel is moved for the purpose of opening the register the connecting-rodj j is raised with it, and also that side of the valves to which the connecting-rod is attached is raised, and consequently opened in proportion to the distance which the wheel is moved. The opposite motion cannot fail to close the valves of the register. The top of the wheel G is notched, as at n n, so that the foot will act upon it with more certainty. 'There is a recess around the wheel in the surface of the register, as at o 0 0, for the purpose of giving free access to the edge or notched surface of the wheel to turn it. The notched edge should be flush with the surface of the register.

Having thus briefly described the construction and operation of my register,I will briefly state what I believe to be new about it, and what are some of the improvements made.

I regard as new the adoption of the upright or vertical wheel, or segment of a wheel, as a moving power, together with the arrangement of the connecting-rod,which moves in a circular direction with the wheel, the said rod being attached to the valves, as previously described.

- The improvements attained are (some of them) as follows: The vertical wheel or segment by itsiposition enables persons to impart i What I do claim, anddesire to secure by motion to it with the'foot (when placedin the Letters Patent, isfloor, as it more commonly is) without stoop- The application of the upright or vertical ing down,thns being an improvement in point wheel or part or segment of a wheel to the of convenience; second, the employment of opening and closing of hot-air registers and the wheel and connecting-rod very greatly diventilators, the edge or periphery of which is minishes friction, giving it an advantage in placed flush, or nearly so, with the top suropening with more ease than any register now face of the register, and can be acted upon by in use; third, from the nature of itsconstructhe foot, if desired, the wheel or part of a tion it needs no holder, key, or other device, wheel so placed imparting motion to thevalves which may or may not be at hand when needthrough a connecting rod or rods, which are ed to open the register, being animprovement connected or attached to-the wheel at a point in point of time in opening, and also safety distant from its axis and to the valves by pins from burning thefingers; fourth, my arrangeat a distance from their centers of motion, the ment enables me to place my machinery for connecting rod or rods moving in a circular opening and working the register compactly direction with and corresponding to the mo- 1 in one end of the register. In this position tion of the valves that are moved.

they afford no obstruction to the free passage of warm air through it, which is very desir- CHAS TUTTLE' able.v Vvitnesses:
