Description
R. S. TEMPEST y Filed April a, 19.25'
ewan/515W@ ATTORNIY WITNESS Patented ct. 13, 1925.
UNITED STATES PATENT OFFICE.
VENTILATOR.
Application filed April S, 1925.
T 0 all whom t may concern:
Be it known that I, RICHARD S TEMrns'r, a citizen of the United States, residing at Mount Pleasant, in the county of VVestmoreland and State of Pennsylvania, have invented new and useful Improvements in Ventilators, of which the `following is a specilication.
This invention relates to a device for drawing gases and other fumes from a room or building, the general object of the invention being to provide a chimney-like device in which is inserted a second device so that a suction is set up in the second device by the draft in the irst device, the sec- 0nd device drawing the gases from the room.
Another object of the invention is to make the parts adjustable so that the flow oi' gases through the second device can be controlled.
This invention also consists in certain other features of construction and in the combination and arrangement oi' the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and speciiically pointed out in the appended claim.
In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denotelike or corresponding parts throughout the several views, and in which Figure l is a longitudinal sectional view through the device and showing the same in use.
VFigure 2 is a top plan view of the device.
Figure 3 is a top plan View of the inner member.
Figure 4L is a bottom plan view of said member.
In these views l indicates the outer or chimney-like member' which passes through a hole in the roof or other part of the building and is held in place by the brackets 2. The member is provided with a flaring lower part 3 and the top is closed by a cross piece 4; which leaves the openings 5 at the sides thereof. A member 6, of the same shape as Seria1 No. 21,635.
member l, though smaller, is held in spaced relation in the member l by means of the long bolt 7 which passes through the cross pieces 4i and 8 and through the spider 9 at the lower part of member 6 where the bolt receives the nut 10 which holds the parts together. An inverted cone-shaped deflector ll is supported by the bolt and nut under the spider. Spring strips l2 are carried by the `flaring' part of the member 6 and engage the flaring part ot the member 1. A handle 13 is fastened to the base part of member 6 so that said member can be turned in order that the openings lett by its cross piece S can be adjusted in size by the cross piece 4 to control the flow of gases through the member 6. 4
From the foregoing, it will be seen that the draft created in member l will act to set up a suction in the member 6 so that the gases and other fumes will be drawn through said member and will escape through the top thereof.
The device can be used in various situations although it is mainly desired to remove fumes and gases escaping from pots used in manufacturing various compounds and articles and in this case the device would be set directlyT over the pots.
That I claim is A device of the class described comprising a chimney-like member having a `daring lower end and a cross piece at its upper end, a second member of? similar shape to the first mentioned member but smaller, said second member being spaced from the lirst member, a spider at the lower end of the second member, a bolt passing through the cross pieces at the tops of the members and' through the spider, a detiector plate on the bolt, a nut on the bolt holding the parts together and a handle on the second member' for turning the same to adjust its cross piece in relation to the other cross piece to control the flow of gases through the same.
In testimony whereof I ailix my signature.
RICHARD S. TEMPEST.
