REGISTER CONSTRUCTION.

Application filed September 13, 1926. Serial No. 135,219.

This invention relates generally to heating apparatus and refers more particularly to hot air registers.

One of the essential objects of the invention is to provide an eflicient register of this type that is simple in construction, neat in appearance and that may be easily and quickly installed, for instance in the floor of a vehicle body.

Another object is to provide aregister in which the hot air from the heater is deflected in such a way by a baflle in the register that a substantially uniform distribution of hot air will be obtainedt-hrough the outlet openings at the top of the register.

A further object'is to provide a registerhaving means at the bottom thereof, preferably associated with the air deflecting means, for permitting dirt and other foreign matter collecting into the register to be discharged therefrom.

\Vith these and other objects in view, the invent-1011 resides in cert-am novel features of construction, combinations and arrangements of parts as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawing:

Figure l is a vertical sectional view through a register embodying my invention applied to a floor of a vehicle body.

Figure 2 is a perspective view of the top or cover of the register.

Figure 3 is a perspective view of the body of the register.

Figure 4 is a bottom plan view of the register. V

Figure 5 is a view similar to Figure 4 but showing a slightly modified construct-ion.

Figure 6 is a top plan view of a slightly modified form of cover.

Figure 7 is a transverse sectional view through the construction shown in Figure 6.

Figure 8 is a fragmentary sectional View of the cover shown in Figures 6 and 7 applied to the lateral flange of the register body.

Referring now to the drawings 1 is a register embodying my invention mounted in the floor 2 of a vehicle body. As shown, this register has a substantially cup-shaped body 3 and an apertured cover 4t and is, adapted to be supplied with hot air by means of a conduit 5 that leads from a suitable heater (not shown). \Vith this construction the control means such as a valve and the like for regulating the flow of air through the register is preferably located in the conduit 5 at a point remote from the register.

To provide an eflicient construction, one side of the body is provided wit-h an inlet opening 6 through which the hot air from the conduit 5 is adapted to flow into the register, while the open upper end of the body is preferably flared as shown at 7 and is provided with the laterally extending attaching flange 8. As shown in Figure 1, this flange is secured by suitable headed elements such as thescrew 9 to the floor 2 of the vehicle body and sci-ms as a hearing or seat for the cover 4. Any suitable means such as the screws 10 may be used for securing the cover L to the flange 8. Preferably these screws extend upwardly through the flange 8 and 'threadedly'engage suitable enlargements 11 of the depending flange 12 of the cover.

Thus these securing elements 10 areefiectlvely concealed when the register is installed. If desired, a suitable annulus or rlng 13 may be used to conceal the edges of the carpet l4 surrounding the register; In

practice this ring 14' is provided with a neat ffinish and is preferably held in place by suitable pins or lugs 16 that project laterally from the'depending flange 12 of the cover.

In order that the air will be properly distributed through the apertures 4 in the cover 4, I have provided a baflle 17 which is secured in the body 3, preferably in rear of the inlet opening 6 and approximately midway between the front and rear walls of the body for deflecting longitudinally of the body the hot air admitted through the inlet opening 6. lVith this arrangement the hot air from the heater entering the register will be divided by the baflle 17 so that a portion of the air will flow upwardly in front of the baifle to the apertures in the cover, while the remainder of the air will flow beneath the battle, thence upwardly in rear thereof to the apertures 4 in the cover 4.

In order that dirt and other foreign matter collecting in the body of the register, may

be discharged therefrom, the bottom 19 of the door 21 and bafile 17. If desired the ac the bottom 19 and door 21.

tuating means may be a coil spring having certain of the convolutions 23 and 2% respectively thereof sleeved upon the hinge pintle 2'5 and having laterally extending arm portions 26 and 27 respectively bearing against (See Fig. 5.) Thus the door 21 may be pressed downwardly against the tension of the spring means to discharge dirt by merely inserting a suitable implement or tool through one of the apertures in the cover 4 andthen pressing the said implement downwardly against the door 21 to uncover the outlet opening 20. Inasmuch as the baflle 17 directs the hot air longitudinally of the body, it will be apparent that a portion of such air will remove the dirt, etc. from the body through the opening 20.

In- Figures 6 to 8 inclusive I have shown a slight modification in which the depending flange 1-2 of the cover isprovided at spaced 7 points with depending lugs 30 which extend through suitable openings 31 in the flange 8 and are riveted thereto.

dispensed with entirely. Thus, a permanent and veryrigid joint is provided.

lVhi-le it is believed thatfrom the foregoing description, the nature and advantage of my invention will be-readilyapparent, I desire to v have it understood that I do not limit myself to what- 1s herein shown and described and that such changes may be resorted to when desired as fall within the scope of what is claimed.

hat I claim as myinvention is 1. An air re 'lster of the class described comprising a body having an inlet opening mally closing one of said outlet openings so that a portion of the air deflected by said bafile towards said opening will flow around L said baffle toward the other of said outlet openings.

2. An air register 'of the class described comprising a substantially cup-shaped body having a lateralinlet opening for air and having; an outlet for dirt and air at the bottom thereof below said opening, a spring actuated door normally closing said outlet open-- ing, and a baifle in said body for deflecting towards said dirtroutlet opening a portion of the air admittedto the body through said inlet opening.

3. The combination with the flooring of a vehicle body having an opening therein, of an air register comprising a substantially cupshaped bod-yin said opening and having a lateral inlet openingfor air below the flooring and having an-outlet for dirt and air in the bottom. thereof below said lnlet opening,
