REGISTER APPLIANCE Filed May 26, 1930 Patented Feb. 9, 1932 UNITED STATES THOMAS OLINGER, OF HOLLAND, MICHIGAN REGISTER APPLIANCE Application flied May 26,

This invention relates to a furnace hot air register appliance, being more particularly concerned with a mounting for a back plate in a register, the adjustment of which controls the quantity of warm air permitted passage through the register. The back plate is mounted for swinging movement about a horizontal axis below which it depends and is frictionally held in any position to which it is moved, being movable toward or away from a grille in front of the back plate which is of an open formation for warm air passage.

The pivotal frictional mounting of the back plate, usually upon a fixed rod, is of a character in which there is liability of wear so that the friction tends to become lessened and there is danger that the back plate will not stay in the positions to which it is adjusted but will, through gravity, overcome the friction and cause the back plate to move to or toward closed position. When the register leaves the factory, or at least after it is installed in a house, the adjustment of the back plate is correct but after use the hinge or pivotal mounting wears, thus lessening the friction so that the hinge becomes loose and then the back plate will close by gravity necessitating further adjustment to hold it open which frequently entails the services and expense of a service man. It is a primary object and purpose of the present invention to provide a particularly simple, novel and effective structure which will maintain a constant friction and takeupagainst ordinary wear indefinitely without further adjusting after the register is properly installed and at the same time provide the usual means of adjustment which the installer is accustomed to.

My invention attains these ends in a practical and effective manner as will be understood from the following description of the invention, taken in connection with the ac comp anying drawings, in which,

Fig. 1 is a perspective view of a furnace register having my invention incorporated therein.

Fig. 2 is a vertical section therethrough.

"Fig. 3, and

Fig. 5 is a horizontal section substantially on the plane of line 5-5 of Fig. 3.

Like reference characters refer to like parts in the different figures of the drawings.

The register casing of sheet metal, indicated at 1, has an opening in its front side, inset in which is an open grille 2 the design of whichmay be greatly varied but through which the warm air passes to aroom. The back plate 3 is a plate of sheet metal and lies back of the grille 2. With my invention, at the rear side of the back plate and at its upper edge portion, substantially midway between its vertical edges, a member 4 in the form of a flat plate of metal is permanently secured, the upper part of which, above the back plate, is formed with a concaved seat portion 5, as best shown in Fig. 4;. Associated with the member 4 and back of the same is a second member 6 of fiat metal which likewise at its upper edge portion is formed with an oppositely disposed concaved seat section 7.

The lower part of the member 6 is pressed rearwardly and offset as indicated at 8. A pin 9, having heads at both ends, passes through the back plate 3, the member 4 and the lower ofl'set portion 8 and also through a curved leaf spring 10 which is mounted between the

parts

4 and 6 and within the recess provided by the off-set at 8 so that it will not turn about the pin 9. j

A screw 11, having a head 11a, passes freely through openings made in the back plate and the member a and threads through a threaded opening in the plate 6. An operat ing handle 12 is formed at its lower end with a bifurcated or divided section 12a permitting the same to be inserted between the head 11a and the front side of the back plate 3, straddling the screw threaded shank 11 whereby the handleis secured to the back plate and extends upwardly and forwardly through an openingin the grille 2 to a posispring 10 is tensioned. The head lla 'o'fth'e screw is readily accessible from the front of the register and quickly operated by a screwdriver and the tension substantially instantly adjusted at any time it becomes desirable to do so.

.I-t is also evident that the assembly of the back plate with the-supporting rod 1-3 is very simple and easily accomplished While the at tachment of the {operating handle 1-2 can be done instantly. Th'espring 10 has the efiect of causing vthe pressure upon the rod 13 to be a yielding andn'ot a binding pressure, thereby insu-ring constant friction as the pivotal bearing wears on the :rod. c

The construction described is very practical for the purposes for which it has been designed. There are various modifications in the detail of structure which can be resorted to. For instance, instead ofa'fl-at leafispring extending the width of the plate 6, a coiled compression spring having a limited numher of cells may be interposed between the parts in place of the leaf spring 10, and the outwardly pressed oroiiset portion 8 will not need "to extend the full width Off the-member 6 :but only be pressed outwardly enough :to receive the coiled spring, a coil spring being the full equivalent to a-leaf spring in this re-- lation. Accordingly, the invention is not "to be limited to the specific detail-described but is to be considered comprehensive of all iorms of structure coming.w ith-in the scope of the claimsappended-hereto.
