REGISTER.

Specification of Letters Patent.

Patented June 22, 1915.

Application filed March 4, 1914. Serial No. 822,357.

To all whom it may concern:

Be it known that I, JAMEs H. BAILEY, a citizen of the United States of America, and residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Registers, of which the following is a specification.

My invention relates particularly to what are commonly termed heating and ventilating registers.

Devices of this character are usually provided with a grille or screen for preventing access of foreign matter into the flue with which the register is connected. It is desirable that this grille while effectually guarding the mouth of the register shall not materially impede the flow through the register. Increase in flow capacity has heretofore been obtained by increasing the size of the openings in the grille and this naturally results in a corresponding decrease or sacrifice in the capacity of the grille as a barrier or guard.

My invention has for one of its objects to gain increased flow capacity without in any way sacrificing the barrier or protective qualities of the register. This object I have attained by employing two grilles, disposed one over the other and with the webs forming the meshes of one grille spaced from and disposed out of alinement with the webs forming the meshes of the other grille. The result of this is a composite grille whose capacity as a barrier is equivalent to the sum of the two grilles while the intervening air space between the grilles allows a greater volume of air to pass through the two grilles than if the two grilles were combined in one plane.

Another object of the invention is to make the register as ornamental and attractive in appearance as possible. The use of the two grilles lends itself admirably to this purpose since by varying the design, shape or color of the respective grilles a great variety of effects may be produced and the parts of the inside grille appearing through the openings in the outside grille give a sense of perspective to the composite design.

The accompanying drawings illustrate lIl concrete form a practical embodiment of my invention, but it will be understood that various changes and modifications may be made without departing from the true spirit and scope of the invention.

Figure 1, is a front View of a so-called base-board register embodying and typifying the invention. Fig. 2, is a perspective disassembled view of the same. Fig. 3, is a vert cal sectional view of the register as-in use 1n connection with the flue box of a wall flue. Fig. 4, is a fragmentary sectional view of a slight modification in the form of the inner grille.

The outer frame or border member of the register is designated 7 in the drawings and as in this particular instance it is to fit the base board of the room it is shown provided with a rearwardly extending top wall 8 and rearwardly extending end walls 9, which as indicated in Fig. 3 fit in the corner formed by the side wall and floor of the room.

The outer grille is carried by the border frame and in the case illustrated it is formed integral therewith. This grille, as best shown in Fig. 2 consists of a series of angularly disposed bars or webs ll spaced to leave eXit openings 12 therebetween.

The inner grille is shown carried by an inside frame 15 and it also consists of a series of webs or bars 16 spaced to provide openings 17 therebetween. This second or inner grille is disposed inside of and separated from the outside grille by an intervening clear space 18 and the webs of the inside grille are disposed out of alinement with the webs of the outer grille so as to cross the spaces or openings in the outer grille. In the construction illustrated the webs of the outer grille form squares disposed in horizontal rows while the webs of the inner grille form smaller squares arranged in inclined rows, the effect being when the register is assembled, a composite design (Fig. 1) consisting of heavy squares in the foreground crossed by diagonals appearing in the background.

The inner frame is supported preferably by being detachably secured to the outer frame. In the illustration this is accomplished by employing screws 21, passed through openings 22 in the border frame into tapped openings 23 in the inner frame. I prefer also to use the inner grille frame 'as a mounting for the fan or valve. I have therefore shown the fan 25 as pivoted at 26 in the rearwardly extending flange 27 of this frame and operated by a hand lever 28 pivoted' at 29 and provided with a segmental slot 30 engaging over a stud 31 on the end of the fan.

V The grilles may be made integral or separate from their supporting frames. Thus in Figs. 2 and 3 the inner grille is shown as made up of interlaced bars having their ends engaged in seats 33 in the rearwardly' extending flange 27 of the frame while in Fig. 4 I have shown the webs 35 of the inner grille as formed integral with the frame. The inner frame in this case also is shown'provided with the rearwardly extending flange 36 to house the fan when in its lowered or closed position. The bearing for the supporting screws 21 is provided in this instance by cutting and bending up a lug 37 or lugs out of the rearward extending flange 36.

In Fig. 3, the register is shown applied to the outlet 40 of a flue box 41. This view illustrates clearly how the two grilles form a compositegrillework whose practical eflect as a barrier is equal to the sum of the two grilles but which on the other hand are capable of passing a volume of air or other fluid greater than if the two grilles were combined in one plane.

As the inner grille is to a large extent protected by the outer grille, it may be made considerably lighter and of less expensive material than the outer grille. This means a reduction in weight and a consequent saving in the cost of manufacture and expense of shipping and handling. By keeping a number of designs of the inner and outer grilles in stock a great'variety of composite designs may be produced on demand and by 7 making up the grilles in different colors in- Q'opies of this patent may be obtained, for

numerable ornamental effects may be obtained.

What I claim is 1. In a register and ventilator, an outer grille consisting of webs relatively narrow and spaced widely apart to provide openings between them of greater area than said webs to thereby constitute a grille whose major portion is made up oi: air passages, and an inner grille disposed behind the outer grille and consisting of webs disposed in line with the air passages in the outer grille and narrower than said passages to thereby interrupt the expanse of the passages in the outer grille without shutting off direct flow through said passages and to thereby constitute a compound grille whose design is a composite of the webs in the outer grille and the webs in the inner grille visible through the passages in the outer grille.

2. A register comprising an outer member having a plurality of intersecting narrow bars forming a grille and rearwardly projecting' border flanges in combination with an inner member having border flanges and narrow intersecting bars forming a grille and means for detachably securing said inner and outer members together with the grilles in spacedapart relation, the narrow bars of the inner grille being in line with the spaces between the narrow bars of the outer grille.
