HOT-AIR- REGISTER.
The present invention relates to heaters for automobiles and more especially to heat controls or registers therefor.
Among the objects of the invention is to greatly increase the area of opening of such registers for the passage of air therethrough.
Another object is to more conveniently control the register.
Still other objects will readily appear to those skilled in the art upon reference to the following description and accompanying drawing in which Fig. 1 is a more or less diagrammatic elevation with parts in section showing the installation of such heaters; I
Fig. 2 is a plan view of the register;
Fig. 3 is a section on line 33 of Fig. 2, and
Fig. 4 is a section on line 44 of Fig. 3.
In the drawings a power unit of an automobile is shown at 10 consisting of an internal combustion engine, with the usual exhaust pipe 11. A not unusual type of heater is indicated at 12 and this consists of a sheet metal casing around and spaced from the exhaust manifold, being open at the front end for admission of a current of air from the fan and terminating at the rear end in a tube or conduit 13 leading to the interior of the vehicle.
Where the tube .passes through the floor board 14 or dash of the vehicle this tube 13 is provided with a cut off or register 20 so that when not needed the heated air may be excluded from the vehicle andin the present instance the register is shown in detail in Figs. 2, 3 and 4.
The register as shown comprisesa tubular member 21 provided with a flange 22 by means of which it is fastened to the floor or dash. the portion 21 passing through the floor and being secured to the conduit 13. The flange 22 is actually a perforated plate with the perforations in the form shown having segmental shape. These perforations are arranged in circular form as shown and cover about two thirds of the circle area leaving a spider 23 covering about one third of the area.
Within member 21 are two nested cups 24 and 25 whose bottoms are provided with perforations of a shape and size similar to those in plate 22. These cups are rotatably mounted in member 21 by securing them to plate 22 by a central pin 26 and nut 27. I
This cup 24 is also provided onone of the spider arms with a lateral enlargement 3O turned up at its ends as at 31 and 32. This enlargement is in length about twice the width of the spider arm at this point.
, Cup 25 is provided with a perforated ear 33 which extends up through the openings in 1 the other two members and is so located as to strike ear 31 when moved in one direction. The movement of this ear 33 is of course limited by the spider arms 23 between which it projects. It is also limited in its movement relative to cup 24 by the spider arm and car 31. I
(Note-In the following description only the lower segmental perforation is men-.
tioned, but it is of course obvious that all of the perforations and spider arms act alike.)
In the operation of the device, looking at Fig. 2, in which the register is indicated as open, the ear 33 is moved counter-clockwise until it touches ear 31, thereby bringing the adjacent spider arm on cup 25 over the left half of the space of the perforation. Ear 33 then carries cup 24, through ear 31, to the right until ear 31 strikes spider arm 23. v The spider arm on cup 25 is thereby moved over to the right to cover the right half of the perforation while the spider arm on cup 24 is moved to'cover the left half. Figure 4 shows the closed position of the several spiders. In order to furnish'a convenient means of operation of the device a push-pull control wire 40 is connected at one end to ear 33 and at its other end provided with a knob 41 located upon the instrument board of the vehicle or any other suitable place. The flexible casing 42 is then secured to the instrument board and to plate 22, the casing being secured to the latter as by a clip 43. 1
Now having described the invention and the preferred form of embodiment thereof, it is to be understood that the invention is to be limited not to the specific details herein set forth but only by the scope of the claims which follow.
I claim 1. A hot air register for heaters comprising a plate having segment shaped perforations therein occupying a circular area, the area of the perforations totaling more than 50 percent of the said circular area, andaperforated slidable shutter adapted in one position to close substantially one half of the area of said perforations and in another position to allow full opening of the perforations on a second perforated slidable shutter adapted in one position to close the other half of said area and in another position to allow full opening thereof.
2. A hot air register for heaters comprising a tubular member having over one end a plate provided with perforations segmem tal in shape and totaling in area about two thirds of the area of said tube, a rotatable cup in said tube adjacent said plate said cup being provided in its bottom with perforations similar in size and shape and adapted to register with the first perforations, a second rotatable cup within the first and having like perforations, and means to rotate said cups to such a position as to cause the webs between perforations of the cups to cover the perforations in the plate.
