CON-IB'INED REGISTER AND VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 282,977, dated August 14:, 18 83.

' Application filed December 27, 1882. (Ne model.)

To all whom it may concern:

Be it known that I, ABRAHAM 1)..GALLEN- 'rINE,a citizen of the United States, residing at Marion, in the county of Grant and State of Indiana, have invented a new and useful Combined Register and Ventilator, of which the following is aspecification, reference being had to the accompanying drawings.

This inventionrelates to combined registers and ventilators, and has for its object to provide a simple, ornamental, inexpensive, and efficient device that serves the combinedpun poses of a heating-register, a ventilator, and a conductor of light. I

In the drawings, Figure 1 is a face ew of my improved device. Fig. 2 is a transverse; sectional view of the same in position. Fig. 3 is a horizontal sectional view taken above the lower register. i

- Referring to the drawings, A designates an annular molding, which is preferably formedfrom a solid block of wood or other material, so that there willbe no joints to become separated and otherwise weaken the ring, having a circumferential shoulder or flange, B, around its inner edge. This annular molding is to be secured, preferably by screws 0, around a cir cular opening, D, in the ceiling or wall of the room, and the edge of a cylindrical chamber, E, projects into the molding and rests against E, at itsfront, is arranged a register, F, that also projects against the shoulder B, and at the. rear end of" the chamber is arranged another register, G, that is fitted in a groove or rabbet, H, in the floor above, or in the wall of the adjoining room. The registers comprise each an annular outer plate, I, formed with slots or openings J, and an independent central portion, K, adapted for rotary movement and having about half as many openings or slots L asthe outside ring, I. This sectional construction of register imparts strength and durabilsections, and the bars between the slots, being shorter, are not. liable to become warped or broken. The interior rotary plate, M, of the register is formed in one piece, with an outer series of slots or openings, N, corresponding to the openingsJ in the outer ring, I and with a central series of openings, 0, corresponding to the openingsL in the central plate or disk, K. The inner plate,- M, is moved to close the openings J and L by means of pins or knobs P, that project through and 'work in segmental slots QQ in the ring I. The central outer disk, K, is pivoted centrally to the plate M, and may be turned on its pivot B, when all the opening's J andL are closed, to throw the latter open independent of the former, by means of an opcrating-knob, S, arranged on the periphery of the disk K, and is adapted to engage a proj ection, T, on the inner edge of the ring I,to limit movement of the said central plate.

when used as a ventilator, the chamber E is provided with an opening, U, in its side, which is connected by a pipe or tube, V, with the chimney or other flue, so that when one of the registers is closed and the other opened all the foul air, gases, vapors, &c., will pass through the open register into the chamber E and out edge, the cylindrical chamber projecting against the said flange and having an opening in its side to be connected with a flue, aregister at the front end of the chamber resting against the said flange, and aregister arranged at the rear endof the chamber in an adjoining,

room, as set forth.

In testimony that I claim the foregoing as my own I have hereto affiXed my signature in presence of two witnesses. I
