*HOT-AIR REGISTER.

S?EGIFICATION forming part of Letters Patent No. 270,832, dated January 16, 1883.

' Application filed November 10, 1882. (No model.)

To all whom it may concern p Beit known that I, PATRICK W. NoLAN, a citizen ot' the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Hot-Air Registers, of which the following is a specification.

This invention relates to a hot-air register which is provided with two sets ot valves, one set being arranged to open inward, while the other opens outward, both sets being opened y and closed simultaneously by the same mechanism. n

In the accompanying drawings, Figure l represents a vertical section in the plane x x, Fig. 2. Fig. 2 is a horizontal section in the plane 1/y, Fig. i. Fig. 3 is a vertical section in the plane z e, Fig. 1, looking to the right. Fig. 4 is a vertical section in the plane x x, Fig..2.

Similar letters indicate correspondingparts.

ln the drawings, the letter A designates the frame, which is secured in the inner wall ot' the due F, and in which are mounted two sets of valves. B B C, the valves B B being made to open inward, while the valves O open outward, as shown in Fig. 1. The valves B B swing on gudgeonsbb, Fig. 4, respectively, which have their bearings in the side plates of the frame A, near their inner edges, and the valves U swing on gudgeons o, the bearings of which are also in the side plate ot' the frame, near their front edges.

Between the gudgeons b, b', and c, close to the inner surface ot one ot' the side plates ot" the frame A, is situated a slide,'D, which is retained by screws d, passing through slots c in the slide,`so that said slide can be moved up and down. From theinnersurtaceof theslide extend a series ot' projections, j', which are arranged in pairs, and each pair ot' projections acts upon a. spur, g, extending from one ot' the valves B B O, as shown in Fig. 1, so that by moving the slide down to the position' shown inFig. l all thevalves are thrown open, and by moving the slide up all the valves are closed. From the inner surface ot' the slide D, near its bottom end,-pro]`ect two studs, 7L h, between which is situated the. cam-shaped head i of a lever, Emwhich has its fulcrum on one of thescrews d. This head is so formed that by turning the lever E in one direction the slide D is moved down, and by turning said lever in the opposite direction the slide D is moved up. By these means a positive movement can be imparted to all the valves. The mechanism is simple and cheap in its construction. 1t must be remarked, however, that this mechanism might be changed without departing from the main point ot'my invention, and 6o l do not wish to coniine myself', therefore, to the precise mechanism shown inthe drawings.

By referring to Fig. l it will be seen that the valve B is ot' greater length than the valve B',

so that when the slide D is moved clear down the outer edge of the valve B strikes the outer wall of the due F, while theouter edge ot' the valve B' leaves a free passage up through the ue fora portion ofthehotair, while another portion is deiiected and thrown against the valves 7o C, and by these valves downwardinto the room. The outer edge of the valve Bis provided with a. recess,j, so that the passage ot the hot air, up through the liuc is not entirely stopped when this valve is thrown wide open; but

while a small portion of the hot air can still ascend through the tlue the largest portion of the hot air is deflected against the valves C, and by these valves into the room. In order to insure this action, the upper ends of the 8o valves `B Bextend somedistance beyond their gudge ns, as seen in Fig. 1.

By means ofthe lever E the position ot' the valves B B O can he regulated so that more or less ot' the hot airescapesintotheroom con- 85 taining the register, and the temperature of the room can be regulated with little trouble.

What I claim as new, and desire to secureby Letters Patent, is-
