Abstract
Abstract A housing for electrically operated typewriters and similar machines, such as Telex machines, is composed of a plurality of individual parts, i.e., front, back, side and top wall members assembled together and secured to a top frame which has a separable coupling device by which the assembly is secured to a supporting base having means for receiving and securing the coupling device and complete a cabinet for the machine enclosed within the housing. Soundproofing of the housing is provided for.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
125 words
In a housing for apparatus which may require servicing, such as electrically operated typewriters and similar machines of which telex machines are an example: base means for supporting thereon apparatus to be housed; a housing shell comprising upright wall members including a front wall member, a rear wall member, and two opposite side wall members; a generally ring-shaped frame member; means securing upper end portions of all of said wall members to said frame member; supporting post means extending upwardly from opposite sides of said base means; and coupling means carried by said frame member for engaging in separable supporting relation with said post means to permit lifting of the housing shell away from the base means to expose apparatus supported by the base means.
Claim 2
Dependent Claim
125 words
In a housing for apparatus which may require servicing, such as electrically operated typewriters and similar machines of which telex machines are an example: base means for supporting thereon apparatus to be housed; a housing shell comprising upright wall members including a front wall member, a rear wall member, and two opposite side wall members; a generally ring-shaped frame member; means securing upper end portions of all of said wall members to said frame member; supporting post means extending upwardly from opposite sides of said base means; and coupling means carried by said frame member for engaging in separable supporting relation with said post means to permit lifting of the housing shell away from the base means to expose apparatus supported by the base means.
Claim 3
Dependent Claim
125 words
In a housing for apparatus which may require servicing, such as electrically operated typewriters and similar machines of which telex machines are an example: base means for supporting thereon apparatus to be housed; a housing shell comprising upright wall members including a front wall member, a rear wall member, and two opposite side wall members; a generally ring-shaped frame member; means securing upper end portions of all of said wall members to said frame member; supporting post means extending upwardly from opposite sides of said base means; and coupling means carried by said frame member for engaging in separable supporting relation with said post means to permit lifting of the housing shell away from the base means to expose apparatus supported by the base means.
Claim 4
Dependent Claim
125 words
In a housing for apparatus which may require servicing, such as electrically operated typewriters and similar machines of which telex machines are an example: base means for supporting thereon apparatus to be housed; a housing shell comprising upright wall members including a front wall member, a rear wall member, and two opposite side wall members; a generally ring-shaped frame member; means securing upper end portions of all of said wall members to said frame member; supporting post means extending upwardly from opposite sides of said base means; and coupling means carried by said frame member for engaging in separable supporting relation with said post means to permit lifting of the housing shell away from the base means to expose apparatus supported by the base means.
Claim 5
Dependent Claim
29 words
In a housing according to claim 1, reinforcing and connecting bar members below said frame ring, and means securing the bar members to contiguous ones of said wall members.
Claim 6
Dependent Claim
17 words
In a housing according to claim 1, cushioning means between said coupling means and said post means.
Claim 7
Dependent Claim
30 words
A housing structure according to claim 1, said coupling means including downwardly opening guide socket structures within which the post means are received by projecting upwardly into the socket structures.
Claim 8
Dependent Claim
36 words
In a housing according to claim 1, means on the lower portions of certain of said wall members and on said base means for guiding the housing shell into aligned stable assembly with the base means.

In a housing according to claim 1, a top closure cover member, and means hingedly securing the cover member to said frame ring.
Claim 10
Dependent Claim
64 words
In a housing according to claim 1, certain of said wall members having vertical grooves therein, and other of said wall members having vertical complementary tongue flanges thereon, said tongue flanges being assembled in said grooves by transverse assembly of the tongues in the grooves to effect joint connections between the flanges, and means effecting frictional binding of the tongue flanges in the grooves.
Claim 11
Dependent Claim
32 words
In a housing according to claim 7, said means for effecting frictional binding comprising friction ribs within said grooves extending in the direction of insertion of the tongue flanges into the grooves.
Claim 12
Dependent Claim

In a housing according to claim 1, said frame member comprising a metal frame ring, and said wall members comprising panels formed from relatively soft plastic material.
Claim 13
Dependent Claim
153 words
In a housing for apparatus which may require servicing, such as electrically operated typewriters and similar machines of which telex machines are an example: base means for supporting thereon apparatus to be housed; a housing shell open at its bottom and rising to a top at a substantial height above said base means; said housing shell comprising a front wall member, a rear wall member, and two opposite side wall members; a mounting frame located adjacent to the top of the shell; means attaching the wall members in housing shell assembly to said frame; and upstanding supports on opposite sides of said base means to which said frame is releasably mounted for thereby supporting the housing shell in apparatus enclosing relation over said base means; release of the frame from said supports permitting lifting of the frame and the housing shell from the base means to expose apparatus supported by the base means.
Claim 14
Dependent Claim
153 words
In a housing for apparatus which may require servicing, such as electrically operated typewriters and similar machines of which telex machines are an example: base means for supporting thereon apparatus to be housed; a housing shell open at its bottom and rising to a top at a substantial height above said base means; said housing shell comprising a front wall member, a rear wall member, and two opposite side wall members; a mounting frame located adjacent to the top of the shell; means attaching the wall members in housing shell assembly to said frame; and upstanding supports on opposite sides of said base means to which said frame is releasably mounted for thereby supporting the housing shell in apparatus enclosing relation over said base means; release of the frame from said supports permitting lifting of the frame and the housing shell from the base means to expose apparatus supported by the base means.
Claim 15
Dependent Claim
30 words
In a housing according to claim 10, all of said side wall members comprising relatively soft plastic panels, and stabilizing bars secured to and between said panels below said frame.
Claim 16
Dependent Claim
54 words
In a housing according to claim 10, said upstanding supports comprising respective posts located at opposite sides of the base means adjacent to side wall members, said frame having downwardly opening sockets within which upper ends of the posts are engaged, and means releasably securing the upper ends of the posts in the sockets.
Claim 17
Dependent Claim
50 words
In a housing according to claim 10, said base means comprising a plate member, stud means on edge portions of said base plate, and guide structure on the lower portions of said wall members cooperating with said stud means to stabilize connection of the wall members with the base plate.
