AIR REGISTER 2 Sheets-Sheet 2 Filed April 4, 1950 INVENTOR ATTORNEYS Patented Aug. 3, 1.9584

AIR REGISTER Marcellus G. Saunders, Jr., Winston-Salem, N. C.,

assigner to The Bahnson Company, Winston- Salem, N. C., a corporation of North Carolina Application April 4, 1950, Serial No. 153,780

1 claim. 1

The present invention relates to registers for use in controlling the distribution of air issuing from a duct into a room.

An object of the invention is to provide an improved construction for an air register having a removable inner frame carrying louvers disposed outside the duct for controlling the direction at which air issuing from the duct opening is distributed into the room.

Another object is to provide an improved construction for the inner, louver carrying frame itself.

The foregoing as well as other objects and advantages inherent in the invention will become more apparent from the following detailed description of a preferred constructional embodiment thereof and the accompanying drawings in which Figs. 1 and 2 are front and rear views in perspective of the improved air register;

Fig. 3 is a fragmentary view in perspective of a corner portion of the removable inner frame of the register;

Fig. 4 is a Vertical section through the register taken on line 4 4 of Fig. 5;

Fig. 5 is a horizontal section on line 5-5 of Fig. 4;

Fig. 6 is a horizontal section on line 6 6 of Fig. 4;

Fig. 7 is a vertical section on line 'I-I of Fig. 4; and

Fig. 8 is a vertical section on line 8--8 of Fig. 7.

Referring now to the drawings and in particular to Figs. 1-3, the improved register is seen to be comprised of an outer, rectangular frame I having an outwardly turned peripheral ange 2 at the rear end and inwardly turned peripheral ange 3 at the front end. For convenience in manufacture the four sides of the frame are made in separate sections and joined together in any slidable manner such as by means of L shaped brackets 4 placed at the corners of the frame but on the rear face thereof so as to be hidden from view.

A sealing gasket 5 extends around the frame on the rear face of flange 2 to prevent escape of any air between the latter and the marginal portions of the wall 6 surrounding the duct opening 'I and ange 2 is provided with a plurality of spaced apertures 8 for receiving screws 9 by means of which the outer frame I can be secured more or less permanently to the wall.

The inner, rectangular frame II is preferably made up from spaced pairs of mutually perpendicular channel members I2-I5. The channels face outwardly and the end faces of the horizontal channel members I2, I3 abut against the end portions of the vertical members I4, I5. To secure the four frame members rigidly together, it will be observed that each of the horizontal frame members I2, I3 is provided with two adjoining tongues I6, I1 at each end thereof which project through slots I8 provided in the ends of the vertical channel members I4, I5. After belng passed through Slots I8 tongues I6 are turned down to lie flat against the vertical channel members I4, I5 thus holding all four frame members together. The other tongues I1 serve a different function to be explained later.

The inner frame II carries two sets of louvers, one set being arranged horizontally for independent angular adjustment about a horizontal axis, and the other set being arranged vertically for independent adjustment about a vertical axis.

As seen clearly in Fig. 3, each of the louvers I9 or the horizontal set has a pivot pin 20 extending axially from each end and these are passed through correspondingly sized apertures provided in the vertical channel members I4, I5. For holding louvers I9 in any desired angle of adjustment, a spring strip 2| is used in each of the vertical channel members. Strip 2I which extends the entire length of the channel and is contained wholly within the same traces a sinuous course under one pin 20, over the next pin 20 under the next adjacent pin 20, etc. Since all of the pins 20 are aligned, spring strip 2I will be bowed into frictional contact with each of the pins thus providing a frictional lock for each of the louvers I 9. To establish the bow in strip 2I for those louver pivot pins nearest the ends of the channel members, the terminal ends of the strip 20 are anchored behind the unbent tongues II previously mentioned and which are located substantially in alignment with the row of apertures in the vertical channel members I4, I5 and hence also the pins 20 to thereby establish for the louver pivot pins nearest the ends of the channel members a frictional lock of substantially the same characteristic as is obtained for the pins intermediate the end pins in the row.

Louvers 22 of the vertical set are pivotally mounted in spaced relation along the horizontal channel members I2, I3 in the same manner as louvers I8. Spring strips 23 bowed back and forth around the pivot pins 24 provide frictional locking for the Vertical louvers, and the terminal ends of the spring strips 23 are anchored in slots 25 in the ends of the vertical channels I4, I5, the

3 slots 25 also being located substantially in alignment with the row of pivot pins 24 so that the end pins get the same characteristic of frictional locking as the intermediate pins.

The inner frame ll with its two sets of pivotally mounted louvers I9, 22 thus constitutes an integral subassembly, and is dimentioned to make a close sliding t within the outer frame l. In the illustrated construction, frame il is longer than it is wide. Also as is evident from the drawings the depth of frame Il is less than the distance between the inwardly turned flanges 3 at the longer sides of the outer frame. Therefore to facilitate installation of the inner frame Il in the outer frame l, the narrow side of the former is passed entirely through the latter from the front or room side into the duct then turned to its proper position in alignment with the opening in frame I and slid forward in the latter until the front face of the inner frame I l is stopped by the inturned flange 3 on frame l.

A pair of spring latches located centrally at the upper and lower sides of the inner frame il and seen particularly Well in Figs. 7 and 8 are used to fasten inner frame I1 in the outer frame I. The toe portion '2l of each latch is biased by a cantilever spring 28 into a correspondingly aligned keeper 29 in the outer frame l and can be released by application of pressure to a linger piece 30.

In conclusion it will be understood that while the illustrated embodiment is preferred, various changes may be made in the construction and arrangement of the component parts without however departing from the spirit and scope of the invention as defined in the appended claim.

I claim:

A rectangular inner frame for air registers comprising spaced mutually perpendicular pairs of outwardly facing channel members, each channel member of one of said pairs having dual adjoining tongues at each end thereof extending through slots in the end portions of the other pair v of channel members, one of the tongues at each end being unbent and the other bent against the bottom of the end slotted channel member to secure said pairs of channel members together, a set of independently adjustable louvers having end pivot pins extending through a row oi longitudinally spaced openings in the end slotted channel members, and a spring strip in each end slotted channel member extending sinuously over and under adjacent pivot pins from one end of the member to the other, the terminal ends of said strip being anchored behind said unbent tongues located substantially in alignment with said row of spaced openings thereby to establish a substantially uniform friotional lock for the pivot pins of all said louvers.
