4 Claims. (01. 98-101) My invention relates to devices, commonly known as registers, for regulating and controlling the discharge of air through and from a flue terminating in a room to be heated or ventilated. The present invention relatesprimarily to registers for use in automobiles to control the discharge thereinto from a pipe or flue of air which has been heated by its passage in contiguous relation to the motor or some part heated by 1') the exhaust gases from such motor.

The general object of the invention is to provide a register of simple construction and of a character such that it may be manufactured at a minimum of expense or cost. 4

It also is an object of the invention to provide a register embodying novel means of a character such that the means for controlling the discharge of air, warm or cold, from the flue may beadjusted readily to any position desired.

To the foregoing and other ends the invention comprehends the construction as hereinafter described in detail, particularly defined in the.

claims, and as shown in the drawing wherein I have illustrated a construction embodying the invention in the form which at present is preferred by me. in the details of construction may be made within the scope of the claims appended hereto with out departing from the invention.

In the drawing:

Fig. 1 is a view showing in cross section the device embodying my invention, also showing in longitudinal section a portion of the front end of a pipe or flue upon which the said device is mounted, and also showing in section a fragmentary portion of a wall of an inclosure such,,for example, as an automobile body;

Fig. 2 is a view in front elevation, looking'toward the left in Fig. 1; and

Fig. 3 is a view in inside or rear elevation of the device shown in Figs. 1 and 2.

In the use of the register for controlling the discharge of warmed or heated air into the interior of the body of an automobile it usually is mounted at the front of'the automobile upon the dash board or any other part or portion of the front wall of the structure. However, it is to be understoodthat the register may be mounted upon the bottom of the automobile. Although the register is intended primarily for use for controlling the admission of heated air to the interior of an automobile body it is to be understood that it also may be used for controlling the admission of air into the rooms of dwellings or oth- 'er like structures.

It will be understood that changes In the drawing I have shown at 1 the outer or discharge end portion of a pipe or flue from which air, usualy heated. is discharged. The end portion thereof projects through an opening 2 provided in a wall 3, such as the front end portion 1 of the body of an automobile. The end of the pipe or flue 1 projects a short distance beyond the inner side of the wall 3 as shown in Fig. 1. The device embodying my invention is mounted on the outer or discharge end of the said pipe or flue. The device comprises a base or supporting member consisting of a plate 5 having an opening 6 centrally located therein. The edge of the said openingisprovidedwith an inwardlyor rearwardly extending flange 7 slotted at intervals as indicated at 8 so as to provide relatively narrow portions which are more or less yielding and which are resilient. The slotted flange 7 is adapted to be inserted in the open end of the pipe or flue 1 and the frictional engagement thereof l with the inner side of the said pipe holds the said base member in position on the said pipe. It will be apparent that the plate 5 may be rotated about the axis of the pipe 1 so as to adjust the same to any position desired. The outer edge of the plate 5 is provided with a relatively wide projection 10 the opposite edges of which have rearwardly projecting I ears 11. These ears are arranged in parallel relation to each other and each of them is provided on its rear edge with a series of 1' notches 12 for a purpose which hereinafter will be explained. The upper edges of the'said ears preferably are concave as indicated at 13.

For the purpose of regulating and controlling the discharge of air or any other gas from the i pipe or flue 1 I'have provided a cover and deflector 15 consisting of a metal plate. An annular portion 16 or the plate 15 is flat and adapted to be seated in contact with the outer surface of the plate 5 outside of and surrounding the opening 6. The outer edge of the annular flat portion 16 of the plate 15 is bent and extended rearwardly as shown at 17. Such rearwardly-bent portion is of a character to add to the ornamental appearance of the register but it also tends to cause greater dispersion of the air which escapes from the pipe or flue 1 and impinges upon the inner or rear surface of the cover and deflector plate 15. The plate 15 is provided with a relatively wide projecting portion 20, the side and end portions of 10 which are provided with flanges 21 and 22 respectively. The side flanges overlie and for the most part conceal the ears 11 at the opposite side edges of the projection 10 of the plate"5.

cover and deflector plate 15 to the ears 11 I have provided pivots 23 which extend through the ears or projections 11 and the side flanges 21. These pivots serve to connect the cover and deflector plate 15 to the ears or projections 11 upon the base member of the register but at the same time permit pivotal movement of the said cover and deflector as indicated by the dash and dot lines at 25 in Fig. 1 of of the drawing.

For the purpose of retaining the cover and deflector both in closed position and in any open position to which it may be adjusted I have provided a spring plate catch 26 upon the inner side of the flange 22. The intermediate central portion of the plate 26' is secured to the corresponding portion of the flange 22 by means of rivets 27. The opposite end portions of the said spring plate 26 are bent inwardly away from the flange 22, as shown in Fig. 3 of the drawing, and terminate in slightly inwardly extending reduced portions 28 the inner surfaces of which are rounded as indicated at 29 in Fig. 1 for engagement with the notches 12 in the ears of projections 11 and also with the rear end portions of the ccncaved edges 13 of the ears 11. When the cover and deflector is in closed position as shown in full lines in Fig. 1 the portions 28 engage the outer edges of the ears or projections 11 in adjoining relation to the notches therein, as shown in Fig. 1. If it is desired to adjust the cover and deflector to an open position it is but necessary to take hold of the edge portion thereof and exert an outward pull thereon, whereupon the outer end portions of the spring 26 will yield to permit the movement thereof over the teeth between the notches 12 to thereby permit the movement oi the cover and deflector to any open position which may be desired. The rounding of the reduced portions 28 as indicated at 29 and the tapering and rounded projections between the notches upon the ears or projections 11 facilitate the movement of the cover and deflector from either closed to open or from open to closed position.

By rotatably adjusting the device with respect to the discharge end of the pipe or flue 1 the direction of the flow of air as it is discharged from the pipe or flue and from the register may be controlled. The frictional action of the portions of the flange 7 intermediate the notches 8 therein operates to hold the device in any position to which it may be adjusted upon the outer discharge end of the pipe or flue 1.

It will be seen by my invention I have provided a register of extremely simple construction and of a character such that it may be manufactured at a minimum of cost and expense, and also that the device embodying the invention is of a character such that it is highly suitable for use in the regulating and controlling of the discharge of ,heated air into the interior of the body of an automobile. I

Although the device has been designed primarily for use in connection with automobile bodies it is apparent that it may be used for controlling the discharge of air into the rooms of structures of other character.

Having thus described my invention, what I claim and desire tosecure by Letters Patent is:

1. A register, comprising a base plate having a projection extending outwardly from one edge thereof the'opposite edges of which are provided with rearwardly extending ears, the said plate having an opening therethrough, a cover and deflector for controlling the passage of air through said opening, the said cover having a projection from one edge thereof which projection is provided with side flanges and an end flange, means for pivotally connecting the said side flanges to the said ears, and means in engagement with the said ears for retaining the said cover and deflector in any position to which it may be adjusted.
