Claims. 98-110) This invention relates to an improved construction for registers used to direct the flow of air from heating and ventilating systems.

A particular object of the invention is to provide a simple and efficient means for operating the vanes of a register-and locking them in adjusted position.

One form of the invention provides an improved arrangement in which the vanes of a register may be set and locked individually in different positions of adjustment in order to direct flow in diiierent directions. In another form the .vanes may be operated simultaneously, or may be adjusted individually.

Another feature of the invention resides in a simplified construction for furnishing the register with stationary deflector vanes.

These and other objects of the invention will become apparent as the description proceeds.

While preferred forms of the invention are disclosed herein for purposes of illustration, it should be understood that various changes may be made Without departing from the spirit and scope of the invention'as herein set forth and claimed.

Fig. 8 is a fragmentary plan view showing a. modifying method of mounting thevanes;

Fig. 9 is afragmentary View similar to Fig. 1 of a modified form of theinvention; I

Fig. 10 is a section taken substantially on the line IIl-ID of Fig. 9;

Fig. 11 is a section takensubstantially on the line Illl of Fig. 9; Y

Fig. 12 is a section takensubstantially on the line I2I2' of Fig. 11.

Referring to the'drawings and more particularly to Figs. 1 to 4 inclusive, the register includes a casing I 0 and side walls II A plurality of vanes I2 are mounted in the casing with their pintles I3 journaled in side walls I I. In the form illustrated in Figs. 1, 2 and 3, a centralgroove .I4 is formed ineach of the vanes. I Land. the pintles I3 are held in. the ends of the groove by any suitable means.

In. order toprovide means for operating the vanes and locking them in adjusted positions, a

\ metal disc I5 is rigidly secured to pintles I3 along one side of the casing, as shown in Fig. 1. These discs are preferably stamped from relatively heavy sheet metal. As shown in the form illustrated in Figs. 1 to 4, the side wall II is formed with an offset I6 above discs I5 and an ear I1 is punched upwardly from the oiiset above each disc. A set screw I3 is threaded through each of the ears and impinges upon the periphery of the disc. The outer flange I9 of the casing is elevated a suificient distance above offset I6 to permit set screws It to lie wholly below the plane of the face of the register. Any suitable ornamental grill may be secured to flanges IS.

The arrangement just described provides a simple and efficient means for adjusting and holding the vanes I2. A screw-driver, or other suitable instrument, can be used to set each of the vanes to the desired position and the corresponding set screw I8 can then be tightened home against the disc I5 to prevent accidental rotation of the vane. This construction permits each individual vane to be independently set so that the register may direct flow of air to different parts of a room as may be desired for a particularinstallation.

Fig. 5 illustrates a modification in which the offset I6 is not present. In this case the set screw I8 may be mounted on any suitable part of the casing, such as the ear 20 pressed from the side wall of the casing.

Fig. 6 illustrates a modification in which each vane is held in adjusted position. by a spring member 2| which has one end attached to the casing and its other end frictionally engaging disc l5. It should be understood that any other I suitable method for applying frictional resistance to the disc I5 will serve the purpose.

The vanes need not be mounted concentric to discs I5 as is shown in Fig. 8 where each of the vanes I2 has one of its long edges mounted on an axis concentric with a disc.

(Fig. 7 illustrates a modification in which a driving rod 22 has a pivotal connection. with each of the discs l5 and an operating lever 23 hasits lower end pivoted on the outside of the side wall of the casing. In this construction, movement of lever 23 operates all of the vanes simultaneously. The pins connecting the lever 23 to the respective discs can be readily removable so that after a simultaneous adjustment of all the vanes has been made, one or more of the pins can be removed to permit an independent adjustment of the vane or vane-s associated therewith. Such independent adjustment can be made at any time. Springs similar to springs 2| of Fig. 6 or any other suitable means can be utilized for holding the independently adjusted vanes in their adjusted positions.

Another feature of the invention resides-in the provision of stationary deflectors 24, see Figs. 2; and 3. The lower edge of each of these deflectors is set in a molding 25 which has a U-shapedbody portion and outwardly extending flanges 26. The molding 25 has its opposite ends suitably attached to the casing, and deflector 24 is merely set in the U channel and retained therein by friction, thereby avoiding the necessity forwelding or other special fastening.

The flanges 26 provide surfaces against which the opposite edges of the vanes may seat, as clearly shown in Figs. 2 and 3, in which it is shown that each vane has one edge seating on top of a fiange 26, and its opposite edge seating on the bottom of a flange 26.

In Figs. 9 to 12 inclusive, the preferred form of the invention has been shown, which form utilizes the principle of selective adjustment of the various vanes either simultaneously or individually as may be desired. In these figures of the drawings 56 indicates generally the casing of the register made up of side walls top wall 52, and bottom wall 54. The rear edges of. the top and bottom walls 52 and 54 are formed in substantially Z shape to provide an expanse 55 substantially parallel to the major expanse of these walls. These parts 55 are apertured at intervals to receive grommet-like members 56 which serve as bearings for fiat spindle-like extensions 51 of a plurality of vanes 58. Preferably, in this form of the invention the spindle-like extensions which are made integrally with the vanes are laterally displaced relative to the longitudinal axis of the respective vanes.

In order that the vanes can be rotated about their respective parallel axes use is made of an actuator plate 68 which is positioned immediately above the top edges of the vanes and which has a plurality of pins 6| depending from the lower surface thereof. The actuator plate 60 has a central extension 62 provided with a curved slot 64 adapted to be engaged by a. roller 65 secured to anarm 66 which in turn is pivotally fastened to the top wall 52 as indicated at 61. The arm 66 has an extreme end portion 68 bent substantially at right angles to the major portion thereof and positioned to overlie a curved locking bar 69 which is secured to the .top wall 52 in spaced relation thereto as shown in Fig. 9. An angle member 18 has one portion thereof in sliding contact with a portion of the arm 66 and has the other part thereof positioned beneath the curved locking bar 69. A screw. ll passing through the part 68 also passes through a threaded aperture in the part of the angle member 18 underlying the bar 69 so that this underlying part can be drawn into such frictional contact with the bar 69 as to lock the arm substantially immovably relative thereto.

The actuator plate 66 has one edge thereof out out in more or less scallop fashion as shown generally at 15 to permit the plate to be moved in such manner as to clear the various bearingmembers 56; it being understood that movement of the army 66 causes movement of plate 68 in more or less arcuate fashion. The pins 6| depending from the plate 60 are adapted to be engaged by tab members 16 extending outwardly from the various vanes 58. In the form shown in these figures the two end vanes are provided with tabs 16 which are made integral with the respective vanes. However, the two inner vanes instead of having integral tabs, are provided with sliding strips 80, the upper ends of which are bent at right angles to form tabs 16. These strips 88 have spaced longitudinal slots 8| for the passage of locking screws 82 engaging threaded apertures in the vanes. The lower ends of the strips 80 are formed in such shape as to provide depending fingers 84. By adjusting the strip 80 relative to the vanes to which they are attached it is possible to cause the openings in the tabs 16 thereof to engage depending pins 6| or in other positions to be out of engagement with such pins. This latter condition is desirable in instances wherein conditions require that one or more of the vanes be locked against movement even though the remainder of the vanes be capable of simultaneous movement. To accomplish thispurpose the bottom wall 54 is provided with a platform member 98 extending completely across the register and the platform member 98 is provided with a series of apertures 9| arranged in arcuate fashion in such relative positions that any one of the apertures of a series can be engaged by the finger 84 secured to a vane associated with the particular series of apertures.

With this arrangement it is possible to unlock a desired vane from the actuator and to lock it in any desired angular position by merely releasing the screws 82 which fasten the strip 80 to the vane, moving the vane to the desired angular position and inserting the finger 84 in the proper aperture 9|. The screws 82 may be tightened to lock the finger in this adjusted position. At the same time the remainder of the vanes can be rotated simultaneously by movement of the arm 66 which causes movement of the actuator plate 60 and consequent rotation of the vanes attached thereto. It is to be understood of course, that while the two end vanes have not been shown as being provided with strips 80, such strips can be included, in which event each vane of the assembly can be either individually adjusted 0r simultaneously rotated.

In addition to serving simply as registers the devices disclosed herein are capable of other uses.

For example, a device made in accordance with any of the embodiments of the invention may have the vanes thereof locked in desired positions and when so locked the device can be secured at any point in an air duct to serve as an aid in directing flow of air through the duct. Particularly, a device in accordance with the foregoing, can be employed to facilitate change of direction of air flow for which purpose the device can be locked in or adjacent to a bend in the duct to prevent the setting up of any currents or the like.

Any of the arrangements disclosed herein may be modified, and if desired, features shown in one embodiment may be incorporated in another embodiment. It will be apparent that the invention provides an improved structure wherein the various vanes may be individually adjusted. Furthermore, the invention provides structure in which the vanes may be simultaneously adjusted through a single actuating device and any or all of the vanes associated vwith such an actuator may be individually, adjusted, and if desired,

. locked in such individually adjusted positions.

vention are to be only those set forth in the following claims.
