REGISTER.

SPECIFICATION forming part of Letters Patent NO. 473,751, dated April 26, 1892.

Application filed July 14, 1891. Serial No. 399,500. (No model.)

To a/ZZ whom t may concern,.-

Be it known that I, THEODORE C. HOWE, a citizen of the United States, residing at Genesee Fork,in the county of Potter and State ofy Pennsylvania, have invented a new and useful Register, of which the following is a specification.

This invention relates to stoves and furnaces, and more especially to the registers used in connection therewith; and the object of the same is to produce certain improvements in devices of this character.

To this end the invention consists in the details of construction hereinafter more fully described and claimed, and as illustrated on the sheet of drawings, wherein- Figure l is a plan View of this improved register partly closed. Fig. 2 is a section across two of the joist-s and the flooring and the ceiling of the room below, showing the damper therein as partly closed. Fig. 3 is a central longitudinal section of the entire device. Fig. 4L is a horizontal section through the center of the joists.

Referring to the said drawings, the letters J J designate the j oists upon which is mounted the ooring F, and to the lower edges of which is secured the ceiling C of the room below.

S is an ordinary stovepipe passing vertically through the ceiling and iiooring midway between the joists, and the products of combustion from a stove or other source of heat are directed into the lower end of this pipe and are led from the upper end to a suitable exit, as will be clear.

R is a register let into the iiooring between the joists and surrounding the stovepipe S, and G is a grating let into the ceiling immediately below the register, as seen in Fig. 3, and also surrounding the pipe S. y The register and grating are connected by a metallic casing M', so that they may be withdrawn together from position. The register comprises a lstationary upper member provided with the usual openings O, and a movable lower member M, oscillating around the stovepipe and provided with openings adapted to register with those in the stationary member when the movable member is properly turned. To effect this movement a rod R is pivoted at P to the casing M and is pivotally connected at K to the movable member, its extremitiesv moving in slots A in the register and in the grating and projecting slightly beyond the same in order that they may be operated by hand. The products of combustion at all times pass through the pipe S, and the heated air around the pipe in the room below passes through the grating at all times but can only pass into the room above when the register R is opened;

The letter W designates the end wall of the casing l between the floor and ceiling and between the joists beneath one edge of the register, so that what heat passes through the grating will have no exit in that direction. Beneath-the other edge of the register in the other end wall W', Ilocate a damper D,whose movable member m turns beneath lips L on the stationary member, the latter in this case being the wall W and the two members having openings O similar to those in the register. Secured acrossthe center of the movable member m is a rod fr, embraced by lips or tongues Z on said movable member, and the extremities of this rod project through slots a in the edge of the register and the grating at -right angles to the slots A. Then the register R is closed and the heat passes through the grating G into the space below the register, the wall WV prevents its escape in one direction, but the damper D may be opened to permit it to pass in the other direction through the flue formed by the two joists, the floor, and the ceiling. This flue may communicate with the chimney or with any suitable eXit.

It will thus be seen that an operator in either the upper or lower room may open or close the register and the damper. When both are open, a portion of the heat in the room below passes into the room above. When the damper is closed and the register open, all the heat that passes through the grating passes also through the register, and when the latter is closed and the damper is open all the heat passes into the flue,while when both are closed there is no result other than would be produced by a solid ceiling.

If desired, various minor changes may be made without departing from the spirit of my invention.

The grating and register and possibly the damper are preferably of cast-iron, although the materials, size, shape, and proportions of parts are not essential.

IOO

an operating-rod connected to the damper and having its ends extending through the upper and lower sides of the box, substantially as2 specified.

In a device of the character described, the combination, with a Wall provided with openings radial to a vcoinrhon centera'nd in- Wardlybent, lips concentric thereto, of a darnper pivoted 'at said center and having registering openings, the periphery of said darhperengaging beneath saidrlips, an operating-handle for the danipelgand a flue lead-y ingffroih the openings, substar'tially as described. y, y

4. 'In a device'of the character described, the coinbiiiatio'n, vvith a Wall provided With openings radial to'a rcommon center and in- 5. In a device of the character described,

the combination, with a vertical Wall located in a horizontal ue Within aliooring, said Wall having openings radial to a common center, of a circular damper pivoted at said center and having registering openings, tongues on said damper, and an operating-rod secured across the damper beneath said tongues with its extremities proj ectingthrou'gh 'th'eslots in the ceiling and ioor, as and for the purpose hereinbefore *set forth. l i. y y
