11 Claims.

The present invention is in connection with a novel construction of register in heating and ventilating systems for controlling and directing the passage of air into a room or the like from a flue which carries the air, the air moving upwardly through the flue either by natural or forced circulation. Registers of the type to which our invention pertains may be placed in the vertical wall of a room, the vertical side of a railroad passenger car or other enclosure which is to be supplied with the air and at the present time are usually placed at an upper position in the vertical wall, though it is to be understood that the particular location of theregister in the wall is not a necessary feature of the present invention. The air may be warmed during the cooler portions of the year and cooled during the warmer portions. Heated or warmed air should be directed downwardly rather than upwardly toward the ceil ng, particularly when the register is located adjacent the ceiling, while colder air should be directed upwardly from the register. Of course if the register is located adjacent the floor of the room, the direction of the heated or cooled air may be changed.

The present invention provides a novel structure of register in which the air rising in a vertical flue may be readily directed either upwardly or downwardly at a slight angle, not generally exceeding 15 to the horizontal, or the register may be completely closed. It is a primary object and purpose of the present invention to provide a very practical, economically constructed and easily operated register for attaining the advantageous results stated and for adjusting the register for either such upward or downward direction of air with respect to a horizontal plane in a particularly simple and effective manner- The invention may be understood from the following description, taken in connection with the position of the parts when the air is directed upwardly at an angle to'the horizontal.

Fig. 6 is a fragmentary somewhat enlarged horizontal section through the side of the register where the operating handle is located, and

Fig. 7 is a front elevation of the structure shown in Fig. 3. with the handle shown in transverse vertical section.

Like reference characters refer to like parts in the different figures of the drawings.

The register frame ordinarily is of rectangular form and includes upper and lower side and' end members of angle formation having face flanges I and inwardly extending flanges 2. Around the flanges 2 a reinforcing and strengthening frame is made from Z-bars 3, the intermediate web portion of which parallels the flanges 2 and is spaced therefrom, while one of the legs at the ends of the webs 3 are spot-' welded to the rear side of the face members I, while the others extendinwardly over the inner edges of the flanges 2, as shown in Figs. 3, 4 and 5. Such frame structure is not novel and is not, in its specific form, required for our invention. The described structure is that of a conventional open rectangular register frame. Between the upper and lower inwardly extending flanges or legs 2, a plurality of vertical grille bars 4 are mounted and secured in spaced apart parallel relation to each other from one end of the opening in the register to the other. Such frame bar structure also is of a conventional form and the frame and grille bars furnish an environment in which our invention may be utilized.

As shown in Figs. 4 and 5, the register frame is installed in a suitable opening in a vertical wall of a room, railway car or the like. The flue which carries air has a vertical back 6, vertical sides I and an upper closed end 8, and has an opening in its outer side at its upper portion into which the frame of the register is inserted so that air passing upwardly through the line may thence pass outwardly through the register. It is to be understood that the flue does not necessarily have to terminate immediately above the register, but may be carried further upward and have other openings in which air passing registers may be mounted, as in the upper rooms of houses and the like.

At the rear side of the frame an inverted U- shaped bail having parallel spaced apart sides connected at their upper ends integrally by a cross member I0 is located, the lower ends of the sides 9 coming immediately back of the lower horizontal member of the register frame. At the rear side of, such lower horizontal member of the register frame a Z-bar having an intermediate horizontal web II and two end flanges or legs Na and lib is secured, the dependingi flange Ila having screws passing therethrough to secure it to the register frame; and at the ends of the depending flange Ha ears I2 are turned rearnumber in the disclosure, the number of vanesused may be changed without departing from our invention. The vanes include curved rear sections and fiat forward sections which extend substantially tangential to the curved portions, as shown in Fig. 5.

Said vanes at their rear portions are connected by a bar I! of flat metal, the upper and lower ends of which have pivotal connection to ears I8 secured to the rear, edge portions and at the under side of'said vanes, while the middle portion of the bar I1 is pivotally secured to an ear l8 similarly secured to the intermediate vane 14. The lower and intermediate vanes i3 and I4 at their rear edges are slotted so that the bar l'l projects partially into the slots.

The intermediate vane 14 at one end and very near its forward edge, has an upturned ear I! which is pivotally connected to the lower rear end of a lever arm 20 which in turn is pivotally mounted on a pivot pin 2| (Fig. 6) located between the vertical inwardly extending flange 2 at one end of the register and the adjacent Z-bar frame member 3. An arm 22 extends forwardly from the arm 20 and passes through a vertical slot 23 in the face member I of the adjacent end of the register frame. At its outer end the arm 22 is equipped with an operating knob 24, by means of which the lever may be turned about its pivot 2| to swing the inverted U-shaped member or bail 9, Hi from a vertical position, such as shown in Fig. 3, to the inclined positions shown in Figs. 4 and 5, the air directing vanes l3, l4 and I5 being carried by and moving with said inverted bail.

Near the lower end and at one side of the vertical slot 23, a dog 25 is pivotally mounted upon a pivot pin 26. Such dog is manually operated so that it may be swung from the inclined position shown in Fig. '7, to a vertical position. At the inclined position the lever arm 22 may be moved downwardly to its lowest point of travel, whereupon the bail carrying the'air directing vanes is moved to its rearmost position in the air carrying flue, as in Fig. 5. In such position the forward outwardly extending flat portions of the vanes l3, l4 and I5 are upwardly and outwardly inclined at an angle of approximately 15 to the horizontal. When the dog 25 is turned to vertical position a. stop shoulder 21 thereon interposes in the path of movement of the arm 22 and prevents its moving toits extreme lowermost position whereby the vanes l3, I4 and I5 take the position shown in Fig. 4, the outer flat portions thereof in such case being inclined downwardly and outwardly at approximately 15 to the horizontal. On lifting the lever 22 to its uppermost position as in Fig. 3, the vanes and the bail carrying them are swung to a. vertical position directly back of the register, the vanes closing against each other and the lowermost vane l3 coming against the front side and at the upper edge of the upwardly extending leg lib of the Z-bar upon which said ball carrying the vanes is pivotally mounted. In this position, as

in Fig. 3, there is a complete closure against the passage of air.

The face member I, upon which the dog 25 is mounted, may carry indicia which give directions to the operator. For example, in the summer months when cool air is directed into a room or the like, the upper end of the dog will be swung to the left so as to point toward ,the direction appearing as Cooling". In such case operation of the arm 22 downwardly to its lowermost position carries the vane structure to the position of Fig. 5. The air rising in the flue 6 is caught by the downwardly curved rear portions of the vanes and directed outwardly and upwardly at the slight angle to the horizontal shown. During the colder months of the year when warm air is forced or otherwise carried upwardly through the flue, the dog 25 is moved so that its upper end is pointed toward the indication Heating, whereupon operation of the handle 22 downwardly as far as it can go, or until stopped by the shoulder 21, positions the vanes as in Fig. 4 and the rising heated air is caught by the curved rear portions of the vanes and directed outwardly and downwardly at an angle to the horizontal.

The construction described is particularly practical and useful and with it a desired control ofthe air and its direction of entrance to a room or other enclosed space which is to be either heated or cooled is obtained in a very simple and effective manner.

The invention is defined in the appended claims and is to be considered comprehensive of a all forms of structure coming within their scope.
