WARM-AIR REGISTER.

SPECIFICATIGN forming part of Letters Patent No. 715,806, dated. December 16, 1902. Application filed February 26. 1902. Serial No. 95,731. (No model.)

To all whom it may concern:

Be it known that I, THOMAS E. HUNT, acitizen of the United States, residing in Blue Island, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in VVarm-Air Registers, of which the following is a specification.

The objects of the invention are to improve the construction and arrangement of the plates or castings constituting the front, the

top, and the front side corners of the frame or support for a warm-air wall register box or casing; to improve the construction of the tin or sheet-metal body of the register box or casing and its attachment to the plates or casting of the box or casing frame; to improve the construction orjoint at the bottom of the register box or casing for the ready reception of and a close fit around the warmair-supply pipe or boot; to improve the construction and operation of the controlling damper or door for the passage of the warm air from the register, and to improve generally the construction of the various elements which enter into the formation of the register as a whole and the construction and operation of the register.

The invention consists in the features of construction and combinations of parts hereinafter described and claimed. Y

In the drawings, Figure 1 is a front elevation of the register; Fig. 2, a top plan view of the same; Fig. 3, a bottom plan view of the same; Fig. 4, an end elevation of the register; Fig. 5, a vertical cross-section of the register in place on a section of pipe; Fig. 6, an inner face View of the front plate or casting for the register; Fig. 7, an under face view of the top plate or casting for the register, one end being broken Off; Fig. 8, a detail showing one-of the front corners of the body of the register-casing with the attaching vertical corner post or support therefor; Fig. 9, a detail in elevation of one of the vertical front corner posts or supports; Fig. 10, a detail in cross-section of one of the corner posts or supports; Fig. 11, a horizontal crosssection of the register-walls, taken on line 11 of Fig. 5, with the front casing, the swinging door or damper, and the grate removed, showing the convexity of the end plates of the body of the casing for giving a spring action to retain the controlling damper or door in an adjusted position; Fig. 12, an inner face view of one end of the register-body, showing a bow-spring for maintaining the controlling door or damper in an adjusted position; Fig. 13, a horizontal cross-section of the end shown in Fig. 12, showing the attachment of the retaining bow-spring for the door or damper; Fig. 14, a detail showing one corner of a door or damper having a trunnion or journal-pin for suspending the door or damper to swing from the trunnions or pins; Fig. 15, a plan view showing awire gratein one form of construction; and Figs. 16 and 17, sectional detail views, enlarged, of the rear and front joint-sockets, respectively, at the bottom of the shell or casing.

The register is constructed with a front A, preferably of cast metal and of an oblong or square formation in elevation, as may be desired. Thisfront plate or casting A has-a lower solid plate a and an upper plate or bar a and side plates or bars a surrounding an oblong opening A, through which the warm air can flow from the register-box into the room in which the register is located when the controlling damper or door is in proper position. The lower front wall a, and the up per front bar a, forming a portion of the upper wall, are in dilferent vertical planes, with the lower front plate farther projecting than the upper bar, as shown in Figs. 5 and 6, and a horizontal shoulder a is formed on the inner face of the bar or wall at, extending on each side to a vertical shoulder or ledge a from which ledge or shoulder a flange or rim a extends rearwardly, joining at the top a flange or rim a extending rearwardly from the top bar of the front or casting, leaving the front or casting open at the bottom with a shoulder a at the lower end of the ledge 01. on each side. The complete front plate or casing A has a lower plate in a straight vertical plane with upwardlyand rearwardly extending end bars or walls a and an upper cross-bar in a rearward plane to the lower plate, enabling the register to be set with its lower portion projecting from the vertical wall of the room. The flanges or rims form receivers for the end plates of the tin or sheetmetal body of the box or casing, and, as shown, on the inner face of the front plate, below the opening for the outflow of air, are lugs a for supporting the front side or edge of a grate, forming an open partition below and a support for the door or damper controlling the flow or passage of the warm air from the register-box.

The top B of the register is also preferably constructed of cast metal and of an oblong formation, with perfectly square corners. This top plate or casting B has on its upper face a flange or rim B, forming an oblong collar for the attachment of the riser or eX- tension leading to the room above that in which the register is located, which rim or flange surrounds an opening B preferably of an oblong formation. The rear edge of the top plate or casting B has thereon a depending ledge or rib I), and at each end of this plate or casting, on the under face, is a ledge or rib Z). The rear ledge or rib has thereon in the arrangement shown three depending lugs b spaced equal distances apart, two of which are shown in Fig. 7, and each end ledge or rib has thereon in the arrangement shown a single depending lug b and extending out from each rear and end lug is a rest or shoulder b against which the upper edge of the outer tin or sheet-metal plate of the casing abuts when the parts of the register are assembled, while the lugs furnish a separation for spacing the outer and inner tin or sheet-metal walls of the body of the box or casing, so as to form a dead-air space between the two walls. At each outer corner on the under face of the top plate or casting B at the juncture of the rear and end flanges or ribs is a right-angle lug b extending out from which in right-angle relation to each other are rests or shoulders 1), making a square corner for the attachment of the walls of the body of the box or casing, the shoulders or rests b beingin line with the shoulders or rests b of the depending lugs b and b at the rear and ends of the top plate or casting. At the forward terminus of each end flange or rib b is a spacing-lug 11, extending out from which on one side is a shoulder or rest I) in alinement with the shoulders or rests b and b on each end of the top plate or casting for the abutting edge of the plate or wall of the body of the casing. The outer corners and the straight-line faces of the lugs, in conjunction with the shoulders or rests, furnish asupport and contact for the edge of the outer tin or sheet-metal plate of the body, and a support and contact for the inner tin or sheet-metal plate of the body when used is furnished by the under face of the top plate or casting. At the front on the under face of the top plate or casting B, near each end, is a depending lug b the lower end of which comes to an apex, leaving a space between the front face of each lug and the rear face of the front plate or casting of a width sufficient for the reception of the upper edge of the door or damper G, controlling the outflow of the warm air from the register.

At each exterior front corner of the register box, within the rearwardlyextending flanges on the front plate, is a corner post or support 0, (shown in Figs. 8, 9, and 10,) each post or support having a flat wide body or wing c and a flange or wing c, standing in right-angle relation to the body or wing c and having an outward projection when the parts are assembled. The rear edge of the body or wing c has near its lower end a lug or projection c and near its upper end a lug or projection 0 each lug or projection having therein a hole for the passage of fastening screws or rivets. The upper end of the post or support 0 has therein a circular depression c in the form shown in Figs. 8 and 9, which depression furnishes a support and bearing for a trunnion or journal-pin on the upper corner of the door or damper for controlling the outflow of the air from the register, and at the lower end of each post or support C is a projecting foot 0 and depending from the foot and the end of the postor support is a lug c", in which is a hole for the passage of a fastening screw-bolt or rivet, and the foot of each standard when the parts are assembled passes beneath the shoulder a at the lower end of the vertical ledge a of the front plate or casting, giving a counter-support between the corner post or upright and the front plate or casting for maintaining the corner post or upright in a vertical position for the attachment of the front edge of the side walls of the body of the casing, leaving the lower end of the front plate or casting projecting in advance of each corner post or upright.

The construction shown has a double wall for the body of the casing of the register; but the casing can be formed of a single wall for the body. Each wall may be formed of a plate of tin or sheet metal bent into shape to have a wall at each end and a rear wall. The outer wall D at its lower end has an upturned edge (I, and the inner wall at the lower edge has an upturned edge c with a turned-over edge e, which overlaps the top of the turned edge (I, forming aconuection between the two walls or plates at the bottom on each end and the rear side by which the two walls will be held against springing apart laterally or separating, and at the same time a space 61 is formed between the two upturned edges d and e, which space furnishes a socket for the entering of the top edge of the warm-air-supply pipe or foot for the attachment of the register as a whole to the warm-air pipe or foot, so as to have the attachment a close fit, preventing the escape of warm air upwardly into the space between the two walls or plates of the body, which space constitutes a dead-air space and prevents a radiation of heat that might produce injurious effects or overheating of the walls in the use of the register. The socket is rendered tight and close-fitting when the edge of the warm-air-supply pipe or v foot is entered thereinto by reason of the spring action or clasping effect produced by the upwardly-turned edges 61 and c of the plates and the connection of these edges one to the other at the top. The socket is exceedingly simple in construction and at the same time furnishes a close tight fit for the register to the warm-air-supply pipe or foot with an effectual safeguard against the escape of warm air into the dead-air space between the two walls of the bodyor to the outside of the register. The front edge of the ends of the walls or plates of the body of the casing terminate at the rear line of the out wardly-projecting flange or wing c of each corner post or support, so that the main body is complete to the corner post or support,

. which would leave a space for the forward projection of the main plate or casting at the lower end. This space for the outer end walls is filled by a strip of tin or sheet metal D, soldered, riveted, or otherwise attached at the turned ends to the end walls or plates and extending across the front of the register inside, of the lower portion of the front plate or casting, and the ends of the inner wall or plate E are united by a strip E, soldered, riveted, or otherwise attached to the end wall or plate with a space between the two front strips D and E. The front strip D has an upwardlyturned edge 61 with a turned-over interior edge d of the strip D, and at its top the strip E has a turned-over edge e which overlaps the top edge of the strip D, so that the two strips are engaged one with the other and locked against excessive spreading or separation, and when united a space (1 is formed between the upturned edges 61 and 6 corresponding to the space cl between the upturned edges (1 and e, for the purpose of entering the edge of the warm-air-supply pipe or foot, as described for the space 61, and operating in the same manner and for the same purpose.

An open partition or grate extends across the register from front to rear. This open partitioif or grate F in the construction shown in Figs. 1, 2, 3, and 5 isof cast metal having a front barf, a rear barf, and end bars f with cross-barsf from the front bar to the rear bar, leaving spaces between the crossbars and the end bars. This open partition or grate F is located at the upper termination of the front vertical plate ctof the frontcasting A and is of a width to extend across the space from front to rear of the register and, as shown, is supported at its front edge on the lugs a and is held at its rear edge by pressure against the inner wall or plate of the body of the casing; but the grate could be otherwise supported so long as it furnished a guide and support for the door or damper controlling the outflow of air from the register.

register.

The grate instead of being cast could be formed of wire woven together, so as to leave open spaces or meshes for the passage of the warm air, and a grate F of wire is shown in Fig. 15, consisting of a frame f longitudinal wiresf and cross-wires f forming a mesh with square openings; but the form of the mesh or spaces for the wire grate can be other than that shown without in any manner changing the operation of the grate.

A solid door or damper G is employed for directing the outflow of the warm air from the This door or damper, as shown in Figs. 1, 2, 3, and 5, has its upper end entered in the space between the lugs 12 and the rear face of the top bar of the front or casting A, which space is wider at the bottom to permit of the necessary swing of the door. Thelower end of the door, as shown, isinclined, so as to present a sharp front edge which rests on and bites against the upper face of the grate for the grate to furnish a support for the door or damper in its swinging movements, for which purpose the grate is on the arc of a circle corresponding to that described by the lower edge of the door or damper in swinging. The door instead of being heldonly between the depending lugs 19 and the front bar ct can have at each corner a trunnion or journal-pin g, as shown in Fig. 14, to enter the bearing 0 and suspend the door from the corner posts or uprights to permit of the swinging movement. The door can be swung completely forward to close the opening A in the front or casting, or partly back, as shown by the dotted lines in Fig. 5, or completely back, so thatits lower edgeabuts against the rear wall of the body of the casing. It will thus be seen that by means of this swinging door or damper the direction of the outflow of the warm air can be regulated as may be desired for the outflow to pass wholly through the opening A or wholly through the opening B or be split or divided to pass into both openings. The door, near its lower edge in the construction shown, is provided with a handle or lug, by means of which it can be swung into any desired position. This knob or handle can be a solid knob or handle G, as shown in Figs. 1 and 3, or it can be a handle G in the shape of a coil of wire or other metal, the last form of handle being preferred, as it will not become too highly heated. The door should be held in its adjusted position, and for this purpose one or both of the end walls of the body of the easing can be curved inwardly to present a convex bearing-face which will engage the end or ends of the door and hold the door in an adjusted position, and end walls of this character are shown in Fig. 11. Instead of having the end walls furnish the frictional contact for holding the door or damper in an adjusted position springs can be employed for this purpose, as shown in Figs. 12 and 13, in which the spring H is of a curved or bow formation having at each end a tongue it to enter walls h in the end wall of the body of the casing, and the spring is of the requisite elasticity to furnish the necessary pressure for the frictional engagement to hold the door or damper and at the same time is of a nature to give and take in the movements of the door or damper, by which it will be flattened at one end and raised at the other end, according to the direction of movement of the door or damper, and other means than the convexity of the end wall or walls or a bow spring or springs can be employed for holding the door or damper in an adjusted position.

The outer andinner walls when abody with a double wall is used are arranged with the two walls one within the other and interlocked at the lower end by the upturned edges, which form the socket-joint for the lower end of the body. The top plate is placed on the upper end of the two walls, with the spacinglugs of the top plates entered between the walls, and the top plate is secured in place by rivets, screw-bolts, or otherwise passing through the middle lug at the rear side or edge of the plate and the lug at each end of the plate. The corner posts or supports are inserted between the plates of the double walls at each front corner and secured in place by rivets, screw-bolts, or other means passing through the lugs of each corner-iron, which lugs are entered into the space between the walls, with the edges of both the inner and outer walls flush against or abutting the outward-extending rib or flange of the corner-iron. The front strips D and E are interlocked by their upturned and overturned edges and are secured by soldering or otherwise to their respective body-walls, and the front plate is then placed in position and secured by screw-bolts or other means passing through the shoulder or rib a of the front and through holes in the rib or flange c of each corner-iron, completing the assembling of the register as a whole. The front can be removed when the register is to be placed in the wall, and the register without the front can be placed in position and its lowerend entered onto the end of the warm-air-supply pipe or the foot, and when in position the front can be replaced in position, completing the placement of thepegister in the side wall. The projection of the lower portion of the register from the side wall gives an increased opening at the bottom, enabling the full capacity of the warm-air-supply pipe to be utilized in the register. The corners of the casing at the bottom are square, enabling the end walls to be perfectly straight, giving an easier attachment for the warm-air-supply pipe or foot and rendering the attachment and connection safer than with the use of rounded corners and irregular sides. The joint-socket atthe lower end of the casing receives the end of the warm-air-supply pipe or boot, which can be entered into the socket-joint and will be clamped therein and held without requiring any soldering or other securing means, and at the same time the space will be closed against the passage of warm air to the outside'of the easing. The swinging door or damper enables the outflow of air to be all directed through the front opening or all directed through the top opening or divided for part of the air to flow through the front opening and part through the top opening, and these combined features add materially to the register and give increased advantages therefor over registers of the usual construction.
