VENTILATOR Filed March 5, 1929 INVENTOR O ATTORN EY Patented Aug. 18, 1931 UNITED STATES PATENT orrlca EDWARD w. McIN'rYRE, or CLEVELAND, OHIO, ASSIGNOR TO WESTINGHOUSE ELECTRIC & MANUFACTURING 00., A CORPORATION OF'PENNSYLVANIA VENTILATOR Application filed March 5, 929. SeriatNo. 344,567.
My invention is an improvement in ventilators and relates more particularly to ornamental ventilators for street lamps.
One of the objects of my invention is to prevent the cracking or breaking of globes of street or other lamps, by eifective interior ventilating thereof.
Another object of my invention is to provide a ventilator for street lamps which will permit the discharge of the heated air within the lamp, yet which will prevent admission of foreign matter such as water or snow through the discharge openings in the ventilator.
- Another object of my invention is to provide an ornamental ventilator for street lamps which is extremely simple in construction and inexpensive to manufacture.
Other objects and advantages will become more apparent as the following description of an embodiment of my invention progresses, reference being made to the accompanying drawings in which like reference characters are employed to designate like parts throughout the same.
In the drawings- Fig. 1 is a part vertical section through a device embodying my invention and showing the same in use.
Fig. 2 is a front elevation of the top portion of the upper casting.
In carrying out my invention a plurality of superimposed castings are secured together in spaced relation, one of the castings r having a base for supporting the same on the globe of a street lamp.
In the embodiment of my invention illustrated in the drawings, the castings are indicated generally at 1 and 2 respectively, the
40 casting 1 comprising a hollow upwardly converging body portion terminating at itsupper extremity in a dome 3 which is perforated at intervals as at 4. The upper portion of the dome is formed with a spacing shoulder 5 and is apertured at 6 to receive the end of a rod 7. The upper end of the rod is screw threaded at 8 and carries a nut 9 for supporting the casting 1 axially on the rod at the desired position with respect to the threaded end of the rod. The lower end of the casting 1 extends annularly downwardly and outwardlyand terminates in an annular supporting flange 10, which, when the ventilator'is assembled on the globe, rests on. the globe as illustrated at 11. The upper portion'of the globe is provided with an enlarged opening 12 communicating with the interior of the casting 1 and permitting theheated air within the globe to travel upwardly into the casting and then outwardly through the openings lthereof. v I
The casting 2 comprises an annular body having a depending skirt 13 which is spaced from the casting 1 when assembled, to permit discharge of the heated gases passing from the openings 4 to the outside atmosphere. The casting 2 is provided with an inter- 'nally threaded socket 14 into which the threaded end of the rod 7 may be screwed to securely clamp the castings 1 and 2 together 7 in the positions shown in Figure 1. The upper portion of the casting 2 terminates in an upwardly projecting ornamental portion 15 comprising radially extending vanes 16.
The lower end of the rod 7 is screw threaded at 17 into a bracket 18, which is secured on the upper end of a rod 19 by means of a bolt 20.
The invention is applied in use, to a globe 21 as illustrated in the drawings. Heated gases ascending within the globe pass upwardly, into the dome of the casting 1 and through the openings 4 thereof. The gases then pass downwardly between the castings 1 and 2 and are discharged into the outer atmosphere. It will be noted that the skirt 13 extends down over the dome of the casting 1 to within a short distance of the base of the said casting. In this manner I have eliminated the tendency of back draft into the interior of the'globe caused by sudden gusts of wind. I have also eliminated by this means the admission of water or foreign matter into the interior of the globe.
My invention may be manufactured at very little cost, since the superimposed parts 1 and 2 may easily be cast of desirable metal and quickly assembled on the rod 7 supplied from standard stock. By securing the lower end of the rod 7 to the bracket 18, the ventilator 3100 is centered and rigidly held in position on the globe, and lateral movement thereof is prevented.
Various changes may be made in the details of construction and arrangement of parts of my invention Without departing from the spirit thereof or the scope of the subjoined claim.
I claim The combination with a globe havingan opening in the top thereof, of a ventilator including a hollow upwardly converging member having a base seated on the globe over said opening and eXpanding and terminating at its upper end in a dome, said dome being perforated to permit heated air to pass from the interior of the globe, and a second bell-shaped membeiflspacedfrom and supported by the first member and extending annularly downwardly close to the base of said first member, a rod threaded into said second member and extending downwardly into the globe, and a support for said rod Within the globe.
In testimony whereof, I hereunto affix. my
EDWARD W. MoINTYRE.
