United States Patent O REMovAnLE Lavera ornnnrnn REGISTER Wilbert J. Parrish, Battle Creek, Mich., assignor to United States Register Company, Battle Creek, Mich., a corporation of Michigan Application March 16, 1953, Serial No. 342,433

6 Claims. (Cl. 98-110) ri`his invention relates broadly to registers, and in its more speciiic phases to a new and improved register of a type to be mounted in a wall opening for communication with a hot or cold air duct.

Registers having side mounted operators utilize operators which have considerable thickness and make necessary a relatively large opening in order to operably mount the register. it was a recognition of this ditiiculty and the need of a side operated register mechanism, which is thin, with the register utilizing same being adapted to t into an ordinary register opening, which led to the conception and development of the present invention.

ln addition to having air diffusing louvers, the present register includes a louver type damper, and an object of the invention is to provide a novel arrangement of the various louvers to give excellent directional and volumetric control of the air discharged through the register.

Another object of the invention is to provide a novel adjusting means for the damper louvers, said adjusting L.eans being mounted on the outside of the register frame but being so compact and thin that it does not require an excessively large wall opening for reception of the register.

A further object is to provide a novel louver adjusting means which is operable by means of a key rearwardly insertable through an opening in the wall plate of the register, said key being removable after louver adjustment to prevent unauthorized persons from changing the setting of the louvers.

Another object is to provide a novel register having individually adjustable frictionally held louvers for directing the air discharged through the register.

Yet another object is to provide one set of individually adjustable louvers for vertically detlecting the air, and a second set of individually adjustable louvers for horizontally deecting the air. Thus, unusually etiective control and diusion of the air may be eiiected.

A still further object is to provide an improved frame structure which embodies novel bearings for pintles of the air directing louvers.

Another object is to provide a novel register for use under windows and along walls which will insure blanketing of walls and windows with hot or cold air but will so direct said air that it will not directly ascend along walls, curtains and draperies, thus overcoming dust smudging.

Yet another object is to provide a construction which may be easily, rapidly and inexpensively manufactured, may be profitably marketed at a reasonable price, and will be highly desirable and durable.

Still further objects and advantages of the invention will appear as the description proceeds.

To the accomplishment of the foregoing and related ends, the invention, then, consists of the means hereinafter fully described and particularly pointed out in the claitns, the annexed drawing and the following description setting forth in detail certains means for carrying out the invention, such disclosed means illustrating, however,

but one of various Ways in which the principle of the invention may be used.

In the annexed drawing:

Figure 1 is an end elevation of the register, partly broken away and in section, and showing the key engaged with the adjusting means of the damper louvers.

Figure 2 is a vertical sectional view on line 2 2 of Figure 3 and showing how the key may be used to adjust the air directing louvers.

Figure 3 is a horizontal sectional View on line 3-3 of Figure 2.

Figure 4 is an enlarged horizontal sectional view on the plane ot line 4 4 of Figure 1, showing the detailed oonstruction of the damper louver adjusting means.

Figure 5 is a side elevation of the key-operated swingable arm forming part of the damper louver adjusting means.

The drawing discloses a construction which has proven to be commercially advantageous from standpoints of manufacture, sale and use, and while that construction will be rather specifically described, it is to be understood that variations may be made within the scope of the invention as claimed.

A rectangular register frame 10 is provided for reception in a wall opening, said frame 10 having a wall plate 11 to be secured against the wall. To prevent air leakage between the wall and the plate 11, the rear side of the latter is provided with an elastic gasket 12 adjacent its perimetrical edge.

The frame 1t) is constructed from an outer sheet metal frame 13 and an inner sheet metal frame 14, the two

trames

13 and 14 having lateral ilanges 15 on their front edges which are welded together and to the wall plate 11. The end plates 16 of the inner frame 14 are in contact with the end plates 17 of the outer frame 13 and all of these plates are in vertical planes at right angles to the wall plate 11. The end plates 17, however, are wider than the end plates 16 and project rearwardly beyond the latter. The top and bottom plates 18 and 19 of the inner frame 14 contact with the top and bottom plates 20 and 21 of the outer frame 13 and all of these top and bottom plates are in horizontal planes at right angles to the wall plate 11. The inner frame top and bottom plates 18 and 19 are somewhat narrower than the corresponding plates 20 and 21 of the outer frame 13, and said plates 2G and 21 have anges 22 on their rear edges.

The end plates 16 of the inner trarne 14 have inwardly stamped dome-shaped bearing bosses 23 disposed in vertical rows toward the rear edges of said end plates16. The top and bottom plates 18 and 19 of the inner frame 14 also have inwardly stamped bearing bosses 24, these bosses 24 being disposed in rows lengthwise of and to-ward the front edges of said top and bottom plates 18 and 19.

The bearing bosses 23 are centrally apertured to frictionally receive the pintles 25 of a rear set of horizontally disposed air directing louvers 26 which are preferably of` one piece construction. Similarly, the bearing bosses 24 are centrally apertured to frictionally receive the pintles 27 of a front set of vertically disposed air directing louvers 2S which also are preferably of one piece construction.

The rear louvers 26 are independently adjustable to ver- Y notch is formed with a lug 31 for a purpose to appear.

A damper 32 is provided behind the rear louvers 2.o, said damper comprising horizontally disposed pivoted louvers 33 and vertical linksd connecting said louvers 33 for movement in unison. Those louvers 33 have flanges 35 pivoted at 36 to theprojecting rear edge portionsof the outer frame and end plates 17, 'and the links 34 are pivoted at 37 to said anges. A vertically swingable adjusting arm 38 is connected at 39 to one of the links34 and is operable by means of the key 29 (see Figure l) for simultaneously adjusting the louvers 33 to regulate the air output through the register, and the louvers are frictionally held in adjusted position.

The arm 38 is disposed at the outer side of one of the end plates 17, Figure 4, of the outer frame 13 and is pivotally mounted between this end plate and a retaining plate 40, this plate being parallel with said end plate and'being welded to the adjacent flanges i5. The arm 38 is formed with a bearing opening 4l in its front portion, and the adjacent plate 17' has an outwardly stamped bearing boss 42 received in said bearing opening di. ri`he boss 42 has a central opening 43 and the retaining plate 40 has an inwardly stamped boss 44 received in this opening. The portion of the plate 41B around this boss 44 contacts with the outer end or" the bearing boss 42 and with the outer side of the arm 3S. A washer t5 is coniined within the recess 46 formed by outwardly stamping the bearing boss 42, and a rivet 47 extends through this washer and the boss 44 of the retaining plate 40. The arm 38 is thus substantially mounted and will be frictionally held in any position to which it may be swung when adjusting the damper 32.

The key 29 is usable for adjusting the arm 38. The wall plate 11 has a slot 48 through which this key is insertable, and the front end of the arm 33 has a notch 49 to receive the lug 31 of said key as seen in Figure l. The damper 32 may thus be adjusted and the key removed to prevent unauthorized persons from changing the adjustment.

From the above detailed description of the damper assembly it is believed that the construction, use, and operation thereof will at once be apparent, and while there is herein shown and described the preferred embodiment of the assembly, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention having due regard that such words as horiZontaL verticaL ends, front, and back are purely relative, and used as an aid to describing the invention.
