J. MGGREERY. OUTLET GATE FOR VBNTILATORS.
Patented June 1,1897.
UNITED STATES PATENT Trice.
JOSEPH MOCREERY, OF TOLEDO, OII'IO.
OUTLET-GATE FOR VENTILATORS.
SPECIFICATION forming part of Letters Patent No. 583,501, dated June 1, 1897. Application filed October 28, 1896. Serial No. 610,307. (No model.)
T0 at whom it may concern:
Be it known that I, JOSEPH MCCREERY, a citizen of the United States,residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Outlet-Gates for Ventilators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to an attachment to be applied to a system of ventilation.
The object of the invention is to produce an outlet or a gate which is so adjustable that air in variable amounts may issue at different angles.
The invention consists in an outlet gate or nozzle which is axially revoluble and is pro vided with a hood or cover made of several pieces or segments.
I11 the annexed drawings, Figure 1 represents a side view of the device, the hood being partially open. Fig. 2 is a vertical section taken through Fig. 1. Fig. 3 is a front or face view of the device closed.
In the accompanying drawings the letter A represents a cylindrical sleeve for attaching the device to the end of the air-pipe, and such sleeve may have a flange a to give it a finish. Within the flange Ct the sleeve A is provided with a lip (1. Over the exterior of this lip a and within a swell a of the flange a is loosely placed the inner edge I) of the outlet-gate B. The outer edge of the lip a is swelled outward so that the inner end of the gate B is securely held by the lip a from separation from the sleeve A. The outletgate B is loosely held by the lip a, so that the outlet-gate B is revoluble about its axis on the lip a.
The outlet-gate B consists of two portions, the rigid main portion 1) and the hood 0. The hood 0 consists of several segments 0 0'0 of substantially the same shape and size, but overlapping one another, so that they may be folded together. These segments are hinged at their ends to the portion 1) of the outletgate at the opposite ends of a diameter. At one end the segments 0 and c are provided with lugs 01 d, which taking against the edges of the under segments limit the closing movement of the segments 0 and c. The segment 0 is provided with a rim which catches against a rim of the portion 1) when the segments are moved so as to close the outlet. The several segments 0 c c are fitted closely upon one another and are both opened and closed by frictional contact with one another. The segment 0 is provided with a handle D.
As will be noticed the outletgate when closed is globular in form, the hood completing the globular formation. The portion 11, which is a part of this globular formation, is made rounded for a special purpose. It will be noticed that the area of the cross-section of the mouth of the portion 1) is greater than the area of the cross-section of the narrowest portion or the throat of the sleeve A. The dotted line in Fig. 1 shows the position of the outeredge of the segment 0 of the hood 0 when such hood is half-open. WVhen the hood is in this position, the opening in the outletgate is quadrant-shaped. When the air is forced through the outlet, the latter being opened, as indicated, the air is not forced in a straight line, but at an angle. Now by enlarging the outlet-gate beyond the size of the throat of the sleeve, the air, though forced at an angle, will pass out with greater volume, as though ejected in a straight line.
WVith a device such as described air in variable quantities may be admitted into an apartment at variable angles, or it may be completely shut off at any given outlet-gate.
Having described my invention, what I claim isv 1. An outlet gate or nozzle, which is axially revoluble and is provided with a hood or cover made of several movable pieces or segments, as set forth.
2. An outlet gate or nozzle, which is axially revoluble and is provided with a hood or cover made of several movable pieces or segments,
all of the segments but one being provided with limiting-lugs, as set forth.
3. An outlet gate or nozzle, which is axially revoluble and is provided with a hood or cover made of several movable pieces or segments overlapping one another, as set forth.
4. The combination of the sleeve, A, provided with a lip, a, with the outlet-gate, B, consist-ing of a rigid main portion, Z), loosely rowest portion or the throat of the sleeve, A, as set forth.
In testimony whereof I afiix my signature in presence of two witnesses.
JOSEPH MCCREERY.
