, VENTIL'ATORL 7' Specification of Letters Patent; Y Patented Dec. 26, 1906.

Application filed June 30, 1906. Serial No. 324.239.-

To all whom it may concern.-

Be it'known that I, MILES TOWNSEND, a citizen of the United States, residing at Marshall, in the county of Calhoun and State of Michigan, have invented a new and-useful Ventilator, of which the following is a specification.

This invention relates to ventilators for buildings and .other structures.

The object of the invention is to provide a strong, simple, durable, and inexpensive ventilator which is adapted-to be applied to buildings having walls of different thickness and by means of which the structures can be without'permitting the entrance of'rain,

' the following claims without departing from the spirit of the invention or sacrificing any ofits adv ntages.

In the accompanying part of this specification, Figure 1 is averti= cal section through a wall equippedwith one 1 of the ventilators of this invention," Fi 2 is a front view of a ventilator. Fig.3 1s a rear view. Fig. 4fis a detailedsectional view:-

\ The improved ventilator of this inventibn preferably co'nsistsfof an outer member A and an inner member B. The inner member Bpreferably is telescopically fitted into the .rear end of the o'uterm'ember A, so that it can be suitably adjusted therein tofit Walls' Each of the members of different thickness. A and B preferably is parallelogrammatic in cross-section, as shown, so that when the front 'a-nd'rear ed 'es thereof are in-vertical position, so a's-to e in parallelism with the wall or support 0, the tops and bottoms of the members A and B will be upwardly and rearwardly inclined with respect to the front face of the'wall' or support C.

I The outer member A, which preferably is drawings, forming v constructed of sheet metal, is rovided at the front edges of its top 1 wit a depending storm-flange 2 and at the front ed e of its bottom 3 withra, depending storm-t lange 4. At'the forward edges of its sides 5 the outer member A is formed with oppositely and laterally extending storm-flanges 6. As shown in the drawings, the inner and outer ends of the member A are open. Extendin from side to side of the member A in a horizontal direction is a plurality of storm-slats 7, each of which is provided at its opposite ends with depending ears 8, which serve the twofold function of restin against the top of the next lower slat an spacing it properly there: from and of also receiving a rivet or fastening device 9 for securing the slat in position. As shown in the. drawings, the storm-slats 7 preferably are more inclined thanthe top and bottom. of the member A, so that when said member is in osition theslats will incline rearwardly and upwar ly.,

' Each of thestorm-slat-s 7 at itsforwar edge is formed with adepending storm-flange 10, which is parallel with the laterally-extending stor'm-flangesfi on the sides 5 of the member A. As shown in thedrawings, all the storm-flan es 2, 4, 6, and 10 are in the same vertical ane at the forward end of the 'member A; ach of the storm-slats 7 at its rear end is provided with a forwardly and upwardly directed storm-flange 11, which is disposed in a horizontal plane considerably above the lower edge of the de ending storm- -flan e 10 of the next hi her s at 7 In rear of t e-storm-slats 7 an about midwa is provided with a vertically-disposed upper screen-slat12 and a vertical y-disposed lower screen-slat 13, each of said slats be1n formed, preferably, with rearwardly-exten ing ears be tween itsfront and rear ends the mem er A 14, which are riveted, soldered, or otherwise suitably secured to thesides 5. of the member A. Each of the screen- slats 12 and 13 preferably consists of a strip of metal folded lon- ,gitudina'lly upon itself to form op ositely-extendingslots into which are fitte the upper and lower edges of a screen 15. By foldlng the screen- slats 12 and 13 upon themselves inthe manner described the screen 15 is. held securely-in place in a-strong, simple, and durable manner. erablyv is raised slightly above. the bottom-3 of the member A to form a narrowslot 16, which constitutes an esca e-opening in the event that any water sho (1 by any chance The lower screen-slat 13-pref- IIO when the member B is drawn rearwardly in the member vA will contact with the vertical guard-flange 17, so as to limit the rearward movement of said member B and also act as a watershed whenever necessary to permit water to run downward from the bottom of the inner member B onto the bottom of the outer member A in the event that water should ever penetrate .so far into the ventilator. The rear end 22 of the member B is provided with a centrally-disposed rectanguar door-opening 23, which is adapted to be closed by adoor 24, pivotally mounted upon a bar 25, extending along its upper end and suitably connected with the sides 26 of the member B. At its lower end the door-24 is provided with a forwardly-extending bracing-flange 27, which when the door is opened is adapted to contact with. the top 28 of'the member B and limit the upward movement of said door. As shown in the drawings, the

door 24 is mounted entirely within the rear end of the member B, so that it can only swing in a forward and'upward direction. On its rear face the door 24 is provided with a pair of securing devices or eyes 29,'with which is detachably connected a springbracket comprising a pair of diverging arms '30, integrally connected at their rear ends by resilient coils 31. By forcing the diverging arms .30 toward each other their forward ends can be readily disengaged from the eyes 29. The upper arm 30 of the spring-bracket preferably is so shaped as to be approximately parallel with the topof the member B. At their forward ends the arms 30 are bent, as indicated at 32, to form broad bearing-shoes, which are fitted flat against the rear face of the door 24 and serve to prevent the bracket from: swinging laterally within the securing devices 29. Suitably secured .to the eyes formed by the spring-coils 31 is a flexible closing element or cord 33, which extends through a 'de member or eye 34. at the central portion of-the upper end of the inner member B, after which it extends through a similar'guide member 35 at one side of said member'B. Also secured to the eyes or coils 31 is a flexible opening element 36, which extends through a guide member 37 at the lower end of the member B and then through the guide members 34 and 35. By drawin upon the closing member 33 the rear end 0 the spring-bracket, consisting of the arms 30 will be drawn upward, thus closing the door,

'ing stormand by loosenin the closing element 33 and drawing upon the opening element 36 the door. will be 0 ened and held in raised position. It will e understood that whenever desired the door 24 can be provided with a suitable lock or latch 38 for securing it in closed osition. that w enever it is desired to leave the ventilator permanently in closed or opened osition the springbracket, consisting o the arms 30, can be detached from the door 24, together with the flexible elements 33 and 36. Furthermore, the spring-bracket can be detached from the door for convenience in shipping the ventilator.

By reason of the fact that the outer and inner parallelogrammatic members A and B are telescoped together the improved ventilator can be easily and uickly adjusted to the thickness of any wal in which it isdesired to place the same. By reason of the peculiar shape of the members A and B their top and bottom portions will incline upward from their outer to their inner ends when they'are properly secured in a'wall, for which reason the penetration of water into a room through the ventilator will be impossible, and

' an upward current of fresh airwill be induced.

The improved device of this invention is strong, simple, durable, and inexpensive in construction, as well as thoroughly efficient in operation.
