GEORGE SMART, on ST. LOUIS, MIssOURI, ASSIGNOB rro HIMSELF AND DANIEL B. TAYLOR, or SAME PLACE.
VENTILATOR.
SPECIFICATION forming part of Letters Patent No. 280,526, dated July 3, 1883.
Application filed October 6, 188 2. (No model.)
T all whom it may concern.-
Be it known that I, GEORGE SMART, of St.
- Louis, in the county of St. Louis and State of to the inner end of the arm A as shown.
Missouri, have invented a new and Improved Ventilator, of which the following is a full, clear, and exact description.
The object of inyinvention is to provide a new and improved portable ventilator, which can be erected for use and taken down very easily, and can be adjusted as may be desired.
The invention consists in a ventilatorformed of an elbow provided with an adjustable mouth and a valve, which, when closed, admits the air into the room, and which, when opened, permits the air to pass off at the elbow.
The invention also consists in a device for adjusting the mouth of the ventilator for holding the ventilator in place, and in other parts, as will be fully described and set forth hereinafter.
Reference is to be hadto the accompanying drawings, forming part of this specification, in which similar letters of reference indicate cor responding parts inall the figures.
. Figure 1 is a side elevation of iny'improved ventilator, showing it erected for use. Fig. 2 is a front elevation of the same. Fig. 3 is a longitudinal sectional elevation of the same.
An elbow, A, has its vertical arm A made tubular, and its other arm, A increases in diameter toward the outer end, and to the same an upwardly-projecting U-shaped frame, B, is hinged at b, to swing to the position shown in dotted lines, Fig. 3, to which frame apiece of fabric, 0, is attached, which is also attached The said arm A is provided in its top with an opening, D, at its inner end, the said opening being directly in front of the line of contact of the elbow-arm A and the lower edge of the fabric 0. A bar or rod, E, is pivoted to the U shaped frame B, and by means of the same the said frame can be'adjusted at the desired inclination. The bar E has apertures a, through which a stud, d, on the elbow A is passed, whereby the frame B can be locked at the desired inclination. The mouth of the ventila tor' is thus made adjustable, and its size can be increased or decreased, as circumstancesmay require. If desired, the free endof the bar E can also be secured to a window or door frame. The elbow A is provided at its angle with an aperture which can be closed by a swinging cap-valve or curved plate, G, hinged to the elbow. A cord, H, attached to the outer edge of the cap G, passes through loops 9 g on the elbow. By pulling on this cord the cap or valve G is swung over the opening in the elbow, which is'thus closed. A cord, J, attached to the cap G, is used to open the same. A flexible conductor or tube, K, preferably made of fabric, is attached to the vertical arm of the elbow, and conducts the air into the apartment. ject down from the lower edge of the vertical arm of the elbow, and are used to hold the ventilator in the desired place. For instance, they are passed over a window-frame, shutter, door, &c., and they will hold the ventilator on the said door, shutter, &c. The mouth of the ventilator can easily be adjusted, as stated above, to catch and admit a greater or less quantity of air, and by opening the cap G the air can pass direct through the horizontal arm A of the ventilator. If the cap G is closed, the current of air passes down through the tube K into the room or apartment, and will not create a disagreeable draft.
Having thus described my invention, I claim as new and desire to secure by Letters Patent Two parallel bars or rods, M, pro- 1. In aventilator, the combination, with the elbow A, of the hinged frame B at the front end of the same, and the fabric 0, attached to the said fram'e and to the elbow A, substantially as herein shown and described, and for the purpose set forth.
2. In a ventilator, the combination, with the elbow A, of the hinged frame B at the front end of the same, the fabric 0, attached to the frame B and to the elbow A, and the pivoted rod or bar E, substantially as herein shown and described, and for the purpose set forth.
3. In a ventilator, the combination, with the elbow A, of the hinged frame B, the fabric 0, the bar E, provided with apertures a a, and the pin d on the elbow A, substantially as herein shown and described, and for the purpose set forth. 4. 'In a ventilator, the combination, with the elbow A, of'the hinged frame B, the fabric 0,
and the hinged cap or valve G, substantially as herein shown and described, and for the purpose set forth.
5. The combination, with the horizontal and vertical pipes of a ventilator, of the elbow A, having a hole horizontally through it, the cap or valve G, hinged to it to cover said hole, the cords H J, secured to said cap, and the loops g g on the elbowto support the cord H, where by a portion of the air coming in at the cowl may be allowed to pass out at the elbow, as shown and described.
6. The combination, with the elbow A, joining the horizontal and vertical arms of a ventilator, of the bars or rods M, secured thereto and adapted to be fastened at their other ends, as described, whereby the ventilator is supported, as set forth.
GEORGE SMART.
