FERDINAND F. SCHUPP, 01E LOUISVILLE, KENTUCKY,

VENTILATOR.

To all whom it may concern:

Be it known that I, FERDINAND F. SoI-IUPP,

among other formations and arrangements within the spirit and scope of my invention. An object of the invention is to provide a devicewhereby ventilation is possible in all manner of weather without the entry of any foreign matter therein.

A further object of the invention is to provide a ventilator having means for varying the opening into the casing thereof.

A further object of the invention is to provide a ventilator elevating means for an adjustable ventilator whereby the adjustment is possible without materially changing the structure or design thereof.

A furtherobject of the invention is to provide means for elevating or lowering the cover of a ventilator of a simple, eflicient and practical type.

A further ob ect of the invention is to provide means for preventing the entry of rain, snow and so forth, and still permit entry or departure of air to and from the ventilator when the cover thereof is in normal lowered position.

A still further object of the invention is to provide certain improvements in details of construction and arrangements and comblnations for the production of .a highly eflicient and practical ventilator.

The invention consists in certain novel features in construction and in combinations,

and arrangements as more fully and particularly pointed out and specified hereinafter.

Referring to the accompanying drawings, Figure 1, is a vertical section. Fig. 2, is a horizontal section taken on the line ctr-a, Fig. 1. Fig. 3, is a horizontal section taken on the line b-?), Fig. 1.

In the particular example illustrated, I show the casing 1, having its upper edge outwardly and downwardly flared to form Specification of Letters Patent. te t 14, 191

Application filed October 11, 191-5. 7 Serial No. 55,266. I i

the portion 2. oally placed across the upper end of themeing 1. At'their outer ends these cross bars 3, are'shaped to conform withthe portion 2, and fastened rigid therewith byan-y suit- Cross bars 3, are diametri- I able means such as bolts orv rivets 4t, and are then turned upwardly to provide the vertimeans 6, is fastened'to' the standards 5. This band or member 6, completely encompasses the top of the casing 1, and its function will be pointed out hereinafter.

Within the casing '1, and suitably fastened to the inside thereof, I provide the guides" or slotted members 7. These members 7 are placed directlybeneath the cross bars 3, where they meet the edge of the casing. Hence, in the particular example illustrated, I provide four of these guides. Di-

rectly above the guides 7 and in alinement therewith, the cross bars 3, are likewise slotted to form guides. The purpose of these guides on the interior of the casing and in the cross bars will appear in the following description.

Slidably mounted'in the guides 7, and

the slots of the crossbars3, I show the rods 8. These rods in the specific example illustrated, are fastened to, and made rigid with a spider or other suitable supporting and bracing means 9, by means of nuts 10, work- .ing on threads provided ,on the ends of the rods 8. At their upper ends these rods 8,

are provided with brackets or supports 11, which are inclined downwardly from the horizontal at an angle approximately equal to the incline of the flared edge 2.1

Any suitable cover such as 12, is provided and carried by the brackets 11. The edges of the cover 12, project beyond the brackets 11, at a distance permitting the cover to be lowered below the horizontal plane of the top edge ofthe member 6.

Now, it is seen that I provide a frame composed of the spider 9,-and the cover 12, rigidly joined by the rods .8, andthat this frame is adapted to be raised orlowered, guided by and sliding in. the guides 7 and the slotsin the cross bars 3.

Any suitable means may be provided for raising or lowering the top of my ventila cal standards 5. A band or any appropriate At the intersection of the cross bars 3, by any suitable means such as 13, I fasten the pulley or block 14. This pulley 1 1, depends from the under side of the cross bars 3, directly below their intersection. At the center of the spider 9, I form a hole or opening and to one side of this center opening, I provide an opening such as 15, having a narrow slot formed from one edge thereof. A rope line, or any other suitable flexible member 16, having a ball 17, at one end and the balls 18, and 19, at suitable distances therefrom, is passed up through the central opening of the spider 9, over the pulley 1 1, and down through the opening 15. The ball 17, prevents this member 16, from passing completely through the opening at the center of the spider. It is understood, of course, that these balls on the line 16, are fastened or formed rigid therewith. The ball 19, is passed down through the opening 15, and then moved under the narrow slottherefrom and this slot being smaller than the diameter of said ball prevents it from passing therethrough. Hence, it 1s seen that by means of the calls 17 and 19, and the line 16, the frame which is slidaoly and loosely mounted in the aforementioned guiding means and carries at its upper end the cover 12, is held in normal closed position, as shown by Fig. 1.

ins operation of my device is as follows: The frame and cover being in the position shown in Fig. 1, it is desired to raise the cover and increase the distance between it and the member 6, thus permitting more air topass into or out of the casing 1. The lower depending end of the line 16, is pulled downwardly. N ow this line working over the pulley 14, when pulled in this manner, will exert an upward pull on the spider 9, through the medium of the ball 17, bearing against the under side thereof. As the spider 9, is pulled upwardly it will raise the cover 12, which is rigid with the rods 8, which in turn are rigid with the spider and the entire structure will be guided and steadied in this movement by the guides 7 and the slots in the cross bars 3. The ball 18, will be placed at such a distance from the ball 19, that when the cover 12, has

reached the desired height it will have passed through the opening 15, and may Copies of this patent may be obtained for all times and in any weather.

then be placed'under the slot therefrom where it will retain the sliding frame and cover 12, in the desired position.

When it is desired to lower the cover, the reverse of the above operation is performed, with the exception that gravity will be the exerting force, and the line 16, passed upwardly until the ball 19, reaches the opening 15, where the movable structure may be retained in the proper position by this ball 19. In regard to these balls 18 and 19, they may be placed at any required distance so as to increase or decrease the height to which cover 12, may be raised or to which it may be lowered. This adjustment, of course, depending on the requirements for the ventilator. A smaller adjustment of this height can be made by means of the nuts 10, on the threaded ends of the rods 8.

\Vith the hereinbefore described ventilator, it is possible to obtain ventilation at As will be seen by the drawings when the cover is lowered a somewhat tortuous passage is formed for the air toenter, doing away with the possibility of rain, snow and so forth, entering in stormy weather. Thus the casing is never closed and air may enter or leave at any and all times. The cover may be glass or solid and of any desired shape and the slopes of the flax-e2, or of the brackets 11, may be changed.

What I claim is:

In a ventilator, the combination of a casing, a band of greater diameter than said casing fixed at the upper edgethereof and extending a distance above and below said edge, with a vertically movable cover of greater diameter than said casing and of smaller diameter than said band, and adapted to lie in normal elevated position with its eifective peripheral edge a distance above the upper edge of said band and means for raising and lowering said cover and maintaining the same in normal elevated position.

In testimony whereof I afiix my signature in the presence of two witnesses.
