Specification of Letters Patent.

Patented Nov. 30, 1909.

Application filed February 15, 1906. Serial No. 301,133.

To all whom it may concern:

Be it known that I, EDWARD D. HOUSE, a citizen of the United States, residing at New Britain, Hartford county, Connecticut, have invented certain new and useful Improvements in Registers or Ventilators, of which the following is a full, clear, and exact description.

y invention relates to registers and ventilators.

The object of my invention is to provide a top or face plate that may be constructed readily and which, though light, is very strong, and requires only a minimum amount of metal. It provides a maximum air passage and will not collect dust.

The invention consists in improvements, the principles of which are shown in the accompanying sheet of drawings. The parts are constructed preferably of sheet metal.

Figure l is a plan view of a top or face plate for a register or ventilator embodying my invention. Fig. 2 is a vertical central longitudinal sectional view of the same. Fig. 3 is a central transverse sectional view at right angles to that shown in Fig. 2.

1 1 and l1 are the sides of the top plate frame, preferably formed of four members secured together at the corners.

2 and 3 are corrugated or zig-zag strips of metal similarly but oppositely arranged, running to opposite sides of the frame, and forming the body, having air passages. They are preferably slightly rounded on the top.

The extreme angles of the strips have flat portions 2 and 3, which abut against each other and act as a means for holding the strips in position. If desired, the strips may be riveted, or otherwise joined at these points, giving the structure a greater rigidity. Riveting, however, requires the cutting or punching of holes, which weakens the metal.

4 is a strip similar to strip 3, but preferably provided with a special opening 5 through which the shutters may be operated when shutters are employed.

66 are angle irons having their horizontal flanges secured to the underside of the frame plates L-l.

are lugs on the ends of the strips (such as 2) which project through openings in the vertical flanges of the angle irons direction to the body strips.

66. The ends may be upset, if desired, to hold them in place more securely. v

88 are angle irons having their horizontal flanges secured to the underside of the frame plates l 1.

99 are bars or beams placed on edge and running underneath and in the opposite These beams support the zigzag strips between their opposite ends and preferably at the apices of the zig-zags which are opposite to the points of support in the frame. The bars or beams 99 are provided with lugs 101O which pass through openings in the vertical flanges of the angle-irons 8-8. The ends may be upset for holding the beams more securely in place, if desired.

1111 are plates in each corner, to which the ends of the sides of the frame are riveted. These plates project into the corners of the opening of the frame, thereby forming means for attaching the frame to the shutter box, when used.

The strips 2, 3, 4 and 9 are preferably set on edge so that a maximum of strength is provided for the weight of metal employed.

The openings between the body strips are very large compared to the strength of the body and the amount of metal used. The strips afford very little resistance for the air that flows through. Being placed on edge, they afford very little space for dustor dirt to collect, either above or below.

The strips 2 and 3 may be of any design or arrangement desired, and the size of mesh may be varied.

All the parts except the rivets may be made from strips of what is known as sheet metal, preferably steel, and they may be readily assembled without expensive machinery. The strips 2, 3 and 4 form the body of the top' plate, which is thus of uniform depth and strength throughout. The beams 9-9 being placed as they are prevent the body strips 2 and 3 from having any tendency to sag or twist. They also hold the said flanges 8-8 together and prevent spreading.

at I claim is:

1. A register or ventilator comprising a broad flat frame, flanges depending therefrom, strips arranged on edges secured to two of said flanges and having openings between them forming air passages, and reinrelatively flat frame members, plates riveted to the corners of said frame members uniting the same and forming attaching members, flanges depending from said frame members, strips arranged on edge and having openings between them forming air passages, and longitudinal means for supporting the centrgl portions of said strips from the under s1 e.
