Description
July 30, 192p. E. MILLER 35. 0 I DAMPER FOR' VENTILATORS Filed June 11, 1926 Patented July 30, 1929.
UNITED s-TAiTEs EQYAL E. PEEL Application filed June 11,
The invention relates to dampers for ventilators, such as are being applied to the roofs of automobiles, and in connection with- I which the dome lamp is mounted.
'inafter described, and is illustrated in the- 10 accom an drawings, in which r Fig. 1 i3 l'etail vertical lon 'tudinal section of the roof of a vehicle an a ventilator and the improved damper applied thereto;
Fig. 2 is a plan view of the improved de- 15 vice detached from the vehicle; Figs. 3 and 4 are detail sectional views taken on the lines 33 and 4-4, respectively, of Fig. 2; and
Fig. 5 shows segmental details of three 26 of the parts of the device.
The roof of a vehicle is re gesented at 10, and as being provided wit a ventilating a erture 11, above which is. mounted a-vent1 ating device 12 of any preferred form.
The dome lamp and damper usually conform in shape and form a closure for the aperture 11. In the illustrated embodiment of the invention this aperture is circular, and the device is given the same form. 3o A circular plate 13, of slightly greater.
diameter than the 'aperturell, is secured to the lower face of the vehicle top by any suitable means, such as the screws 14. This plate is preferably flanged upwardly at its 35 periphery, as shown at 15, to s ace it from the wall surface, and alpertured s, as 16, are formed or aplplie to its upper surface immediately wit n the flange 15 and regisf tering with the apertures for the screws 14. 4o Centrally the plate .13 is curved ulpwardly, as indicated at 17, to'stifi'en the p ate, pro-.
' vide a lamp chamber and-to constitute a refleeting surface. I
A rin 18 depends from the plate 13 and surroun s its curved portion 17 to form an extension of the lamp bod and to carry the lassfront 19 thereof. e inner face of t e lower portion of the ring 18 is concave to receive a glass-holding ring. 20. The'ring is secured to the plate 13 by means of integral lugs, as 21, which project through suitable apertures in the plate, their upper ends being bent down upon the surface of the OE CHICAGO, ILLINOIS,

plate, as plainly shown in Fig. 3. The reflector 17 is apertured to receive and hold a lamp socket 22.
An annular series of apertures, as 23, 'is
formed in the ortion of the late 13 lying between the re ector 17 and t e area within whlch the screw openin s are rovided, and outside of this series 0 openings the plate apertured, as shown at 26, to correspond with the apertures 23, is slidingly mounted the plate 13. I
A controlling knob, as 29, depends below the plate 13, its stem being fixed 1n the regis-' ter late 25, and the plate 13 being slotted, as s own at 30, to ermit its movement for thepurpose of shifting the register plate to bring its apertures into or out of register with the apertures in the damper late. The register plate 25 may be provide with suitable notches or cut-away portions, as 31,to
accommodate the ring-attaching lugs 21,
and in its outer margin is cut away, as indicated at 32, to accommodate the bosses 16 and permit the necessary plate movement.
The damper is readily opened or closed by means of the controlllng knob 29.
Whilea simple and efliclent form of construction is disclosed, various changes of detail may be made without departing from the scope of the invention. I
I claim as my'invention-- 1. A damper for ventilators comprising a fixed plate having an annular series of aper-.
tures, an annular plate in slidable contact with the fixed plate and having an annular series of registering apertures, one of such plates having a circular guide groove outside of its apertures and the other plate seated in the fixed margin of the slidable plate e groove an plate and overlapping1 the inner er olding the FICE. i
