AIR REGISTER Filed Nov. 5, 1942 INVENTOR CHARLES DAVIES ATTORNE Patented Feb. 19, 1946 UNITED STATES PATENT OFFICE 3 Claims.

This invention relates to registers or grills for ventilating or similar purposes of the type comprising an open frame with a set or sets of pivoted blades or louvers across the opening to squeaks and rattles and yet permit of easy movement of the blades.

Another object is to provide a register which shall fulfill the foregoing stated object and yet be simple and economical to manufacture and assemble.

Other and further objects will become apparent from the description hereinafter of the embodiment of my invention illustrated in the drawing in which: a

Fig. 1 is a cross-sectional view of a register constructed according to my invention,

Fig. 2 is a face view of the register of Fig. 1 turned through an angle of 90 degrees, only part of the register being shown, and

Fig. 3 is a perspective view showing my invention applied to a register with a double set of blades.

Referring to Fig. 1, my register comprises an open, rectangular box-like frame I having at one end a circumferential flange 2. A face plate 3 secured to flange 2 by any convenient means may cooperate in securing the register to a wall opening (not shown).

Within the frame a set of blades or louvers to control the flow of air is mounted in the manner now to be described.

Holders

4, 4 are mounted at the inside of the frame at opposite wall and consist of a plate of metal or other rigid material which is apposed to the inside of the frame wall and secured thereto in any convenient fashion as by spot welding. The inner edge of the holder 4 is bent or shaped out and around as at 5 to provide a linear pocket 6. A flat blade or leaf 1 of springy material is inserted at one edge in pocket 6 and is provided near the other edge with a spaced series of openings 8 corresponding with similar openings on the other spring member I. Mounted between the spring members 1 is a set of blades or louvers 9 which as shown in Fig. 1 maybe provided with pivots in the form of ears [0 at opposite ends, adapted to enter and engage in the holes 8. In Fig. 3, I have shown an alternative shape in one set consisting of a sheet of material 9' folded about a pivot pin Ill, but it is clear that the blade may be made in any desired manner or shape. For convenience, the blade 9 may be provided with another ear I l which may be engaged with an operating link I2 so that the blades may be turned as a unit.

In Fig. 3 for a second set of crossing louvers each holder of one set has been reduced to a channel 6' having one edge turned up as at 13 to form a bearing or friction edge. A similar function is obtained in the holder of Fig. 1 by folding back the pocket 6 along the line l3. Before assembly the spring members I are plane. One edge is inserted in pocket 6, the leaves I pressed back and the blade 9 slid in until the ears I!) enter the holes 8. The elasticity of the leaves I holds the'blade 9 firmly in position. At the same time the spring is held firmly in pocket 6 by the fiexure acting against the bearing edges l3, 13'. To support and stiffen the holder the frame I may be turned inwardly as at l4 to provide a backing for the pocket 6; and the face plate may be extended as at iii to provide a stop for the front edge of the leaf 1 as in Fig. 1 and the pocket ii as in Fig. 3. The edge of the blade 9 may be cut away as at IE to reduce friction and permit easier manipulation.

It is to be seen that the assembly of the blades is reduced to just slipping the parts in place; while nevertheless the blades are firmly held in position both initially and over the period of use despite corrosion, dust and other similar factors. It is clear that many variations in detail may be made without departing from my invention,

What I claim is:

1. A register comprising an open frame, pockets secured to opposite inner sides of the frame, leaf springs inserted at one edge in the pockets and provided near the other and free edge with a series of corresponding openings, each pocket being provided with means bearing against the leaf spring intermediate its edges to provide a line over which the spring may be folded, a set of blades across the openings, each blade being provided with means at each end engaged in the openings whereby the blade is pivotally mounted between and held in position by the fiexure of the springs.

2. A register comprising an open frame, a holder secured to the frame and provided with a channel shaped to receive snugly one edge of a flat spring plate, a flat spring plate engaged at one edge in the channel, said channel having means,

against and over which the spring plate may be bent to provide flexure, a blade pivotally engaged with and pressing against the said spring plate whereby both blade and spring are securely held in position. I

3. A register comprising an open frame, pockets secured to opposite inner side of the frame and adapted to receive each the edge of a fiat plate, flat leaf springs having one edge inserted in the pockets and the respective opposite edges free,

said pockets having means to provide a bearing edge over which the leaf spring may be bent, a set of blades across the frame, each blade being mounted in and bearing against the springs near the free edges thereof, whereby the springs are flexed to secure them and the blades in position.
