BOSTON, MASSACHUSETTS.

IMPROVEMENT IN HOT-AIR REGISTERS.

TO ALL PERSONS To WHOM THESE PRESENTS MAY COME:

Be it known that I, WILLIAM HIGHTON, of Mald'en, in the county of Middlesex, and. State of Massachusetts, have invented a new and usefullmprovement in Ventilators or Hot-Airlltegisters; and I dohereby declare the same to be fully described in the following" specification, and represented in' the accompanying drawings, of whichi I Figure 1 is a front elevation,

Figure 2 a rear view,

Figure 3 a longitudinal section, and

Figure 4 a transverse section of a register provided with my invention.

Th purpose of my said invention is to enable the register to be used in a vertical position, in a wall, for instance, with either end or either side upward. It also admits of its beingused horizontally, or set in a fioor., This saves a dealergthe necessity of keeping on hand several different constructions of registers suitable to such purposes. i

The main parts of the register consist of the rectangular frame A, and the series of rotary blinds or shutv ters, B B 13, each of the latter being provided with journals, cl,,at the m-iddles of its opposite ends; These journals rest and turn in bearings into cross-bars a a, fixed in the frame A, close againstits ends.

Each slat has a thirdjournal, b, projecting from an arm, a, such arm being extended from the slat, at one end. of it, in manner as shown in Figures 5 and 6. v

The auxiliaryjournal is arranged ecccn trically with respect to the main journal 0?, of the same end of l the slat. 7

These auxiliary journals extend into slots e e e, made transversely in a slide-bar 0, arranged on one end ofthe bars a. From the bar 0, a journal, f, projects, and enters a corresponding hole made in a wheel, D, which, at its centre, is pivoted to the grate E of the register. Four projections, 7i z' 70, extend from the wheel into the openings Z Z Z Z of the grate, such openings being arranged in acireular path. Each of such projections g it t It has a hole made through it, to receive a cord, m, on whose end a knot is usually made to keep the cord in connection with the wheel. Two of such cords are used when the register is placed so high in a room as to be beyond reach of a person while standing on the floor of. such room, such cords being arranged in two opposite openings of the wheel.

By pulling on one cord, the wheel will be moved, so as to cause the shutters of the register to open apart. By pulling on the other cord, the movement of the wheel will be reversed,-w hereby the shutters will be closed; When the register is placed in a floor, the cords will not be necessary, as the wheel may be moved by the foot or hand of a person applied to one of the projections of the wheel. I

In making the frame A, I form each of its ends with a projecting rib F, formed with recesses 1' r. These recesses are guides for the formation of the holes for receiving the screws 8 s, by which the grate'E is fastened tothe frame A, the recesses being directly opposite the screw-holes made in the grate.

7 Thus the recesses are for the purpose of determining the positions of the screw-holes, which are to be at the centres of the smaller ends of the reoesses,'and thus these recesses greatly facilitate the workman in obtaining the correct position ofthe screw-holes. i

I claim the arrangement and combination of the wheel with the grate, the sliders, and the series of shuttcrs applied to the frame A, as set forth;

I also claim the combination of the frame A and the ribs F with their recesses? 1', as and for the purpose specified.

WM. HIGHTON. I
