7 claims. (ci. 22e- 55) This invention relates to housings for electronic equipment and the like, and more particularly to covers for such housings which are adjustable toward the housing to provide a watertight assembly or adjustable away from the housing to provide a ventilated assembly. The housing and cover assembly of this invention is adapted especially for enclosing electronic equipment which is to be used under submerged conditions where a waterproof housing structure is required for the equip- 'ni'ent or'under such conditions where the equipment is exposed to ventilation purposes and yet the housing and cover' assembly presents a splashproof structure.

.The invention provides a housing having a cover assembled thereon in a manner to be selectively maintained inthe closed or watertight position or in the open or ventilated and splashproof position.

IThe invention also contemplates a particular arrangement for adjusting the cover which permits its manualY operation to secure the cover in its watertight position and its manual release from the watertight position to a selected ventilated position or completed ventilated position.

A specic object of the invention is to provide adjusting apparatus for the cover which insures that it will be maintained in the fully open position. Other objects and advantages of theV invention will hereinafter become more fully apparent from the following description of the lannexed drawings, which illustrate a preferred embodiment, and wherein:

fFig., lv is a perspective view of the assembled housing Cfo'ver of the invention;

.'Fig. 2 is a sectional elevational view of the housing and cover unit in the watertight position;

.Fig 3 is a. viewV similar to Fig. 2 but with the cover in ventilated position; and

Pig. 4 is a view taken on the line 4 4 of Fig. 2 to show a detail of the invention.

`Referring to Fig. l, a housing is shown which may be considered adapted especially for housing electronic equipment and-is formed of a top wall 11 and side, end and a bottom wallwhich are not indicated, but are arranged to provide a suitable pressure tight' or s ealed enclosure. The top" wall.. 1.1 -offthe vhousing Vreceives an adjustable cover having an upper end 12 and an annular side wall 13 which are movable as a unit relative to the top wall 11 of the housing by means of a plurality of adjustable bolt assemblies 14 which will be described in detail.

The details shown in Figs. 2 and 3 of the drawings are similar and as shown, the top wall 11 of the housing is provided with an opening 15 which permits communication with the interior of the housing. An annular ring 16 is mounted on the top wall 11 about the opening 15 and has a lower outwardly extending flange 17 which may be welded or otherwise secured thereto and the ring is also provided with an upper and outwardly extending flange 18. The lower flange 17 is provided with spaced screw threaded openings 20, each of which receives a socket member 21, which is adapted for securing adjustarent 2,325,485 Patented Mar. 4, 1358 ice..-

ber is provided with an inner screw threaded area 22 and an outer screw threaded area'23.

Each bolt assembly 14 consists of a bolt shaft 24 and sleeve 25. The bolt shaft 24 has a screw threaded lower end portion 26 which is received in the inner screw threaded area 22 of a socket member while the sleeve 25 is screw threaded at its inner lower end and is received by the outer screw threaded area 23 of the socket. The sockets provide connecting means between the bolt shafts and the sleeves for releasably maintaining the cover in closed position. When the imperforate cover is in the closed or watertight position of Fig. 2, the screw threaded end portion 26 of each bolt is received in the` threaded areas 22 of the socket while the sleeves 25 are received by the outer threaded sections 23 of the sockets. When the imperforate cover is in the open or Ventilating position of Fig. 3, the sleeves 25 remain fixed to the sockets but the bolt shafts are released and moved axially of the sleeves.

The screw threaded connecting means between the bolt shafts and the sleeves permits ready release of the air vent cover from its watertight position of Fig. 2 and the bolt assemblies are further arranged to maintain the cover in its Ventilating position of Fig. 3. The particular arrangement consists of a spring latch formed, as shown in detail in Fig. 4, of a spring which has one arcuate arm 3l) received or carried by a groove 31 formed in the outer wall of each sleeve 25 and has a spring latching arm or extension 32 which is received in a slot 33 formed tapers downward to form the abutment and to provide,

with the abutment, a locking recess. The latching arm 32 of the spring constantly engages or contacts the bolt shaft 24 and when the shaft is manually moved from its position shown in Fig. 2 to that shown in Fig. 3, the latching arm 32 will be biased into the recess and held by the abutment 35 and thus prevent further upward movement of the bolt shaft and maintain the cover in its completely open or ventilated position. The downward taper ing portion 36 permits the latching arm 32 to readily release the bolt shaft when it is urged downward from the ventilated position of Fig. 3 to the watertight position of Fig. 2 and yet provides an arrangement for securely maintaining the cover in the open position of Fig. 3 under normal conditions of use.

In order to insure that the housing is sealed, a resilient annular gasket 40 is provided and may be disposed between theupper end 12 of the cover and upper ange 1S of ring 16 when the cover is in the watertight position of Fig. 2.A The gasket, as shown, is preferably secured.y

the inner 'face'of the upper end'12 of the cover' by meansV of a bushing 42. The bushing i2 is mounted at the upper end of the bolt shaft 24 and is provided to eect threading the lower end of a bolt shaft to a socket.
