LUDWIG REISCHL, OF NUREMBERG, GERMANY, ASSIGNOR TO BING WERKE, OF NUMBER-G, GERMANY.

oa'nm's mnwnrrme MACHINE.

Application fled Iay 19, 1926, Serial No. 110,052, and in Germany June 2, 1925.

My invention relates to childrens typewriting machines having a standard keyboard, type-carrying levers, a movable carriage and a paper-roller supported in said car'rlage. The ob'ect of the present invention is to simplify t e construction of such machines so as to reduce the manufacturing cost, to faeilitate the assembling of the various parts and to increase production. This I accomplish, by providing a single supporting frame for all the parts and mechanisms of the machine, except the paper carriage, which frame is of U-shape and made of a. single piece of strong but light sheetmetal. This supporting frame with all the parts and mechanisms mounted thereon is then placed in, and secured to, a casing also made of sheet-metal, the rear wall of which easing carries, guide-rails for the movable pa er carriage.

n the appended drawing in which I have shown one embodiment of my invention for the purpose of illustration, Fig. 1 is a side elevation of a machine embodying my invention, partly shown in section to disclose the supporting frame, Fig. 2 is a top plan view of the supporting frame, Fig. 3 a side view thereof, Fig. 4 a top plan view of the outer casing, Fig, 5 a side elevation thereof and Fig. 6 a vertical section along line 66 in Fig. 5.

As seenin the drawing, the outer casing, which receives the supporting frame and which is made of one comprises the longitudinal side-walls 1, 2, and a top wall 3, whichtogether form an inverted U-shaped body. Along their lower edges, the side-walls are bent inwards forming flanges 4, 5 respectively, and in a similar manner, the forward edges both of the. two side-walls and of the top wall 3 are bent over forming flanges 6, 7 and 8 respectively, which flanges impart to the casing rigidity of the casing, fiat strips of iron, 9

iece of sheet metal,

great rigidity. To still further increase the fence is a bent piece of sheet-metal, which is Welded to the flanges 6 and 7 of the side walls, 1, 2. i

v The top wall 3 has a sector-shaped recess. l-l (Fig. 4) along the edge of which is provided an arcuate member 15 of sheet metal enclosing a pad l5 forming a rest for the type-carrying levers when in inoperative position, one of which levers is shown-in outline at 61 in Fig, .1.

At the rear end of the casing, there is fastened to the top wall 3 and the side-walls 1, 2 a transverse rear wall 16, provided along its upper and lower edges with

narrow flanges

17, 18, 19, etc., through which flanges pass screws 20, whereby the said rear wall is secured in position. which in its central upper portion has a recess 21 (Fig. 6) to provide space for the carriage moving device, has secured to its outside surface the guide-rails 22, 23 for'the paper-roll carriage 24 shown in Fig- 1.

The keys, theshift-keys, type-carrying levers and the spacing device are all supported on the supporting frame which will now be described. This supporting frame comprises a flattransverse bar 25 extending across the entire width of the machine and two upwardly inclined side-

members

26, 27

which at their free ends are each formed 7 with an inwardly projecting horizontal flange .28 and 29 respectively screwed, or otherwise secured to the horizontal flanges 28, 29 is a slotted member 31 which acts as a guide for the key-levers and at the same time lends greater rigidity to the supporting frame, 25, 26, 27. The side-

members

26, 27 of the latter are enlarged at their free ends to form triangular-shaped portions 32 in the lower ends of which is journalled the axle 33 of the spacing key (not shown).

On the under side of the transverse bar 25 are provided two

perforated lugs

34, 35 forming the bearings for the axle 36 of the shift keys, one of which is indicated at 37 in Fig. 1. On the upper side of the transverse mon frame, which upon all the various parts being assembled thereon is placed into the sheet-metal casing from the rear thereof, be-

ing secured thereto by screws, whereupon the transverse rear wall 16 above referred to is fastened in place. The assembling and mounting of the parts is thus greatly simplified which for the purposes of mass production is of su reme importance.

While I have escribed my invention with reference to the drawings, I do not, of

course, limit myself to the details of the construction as shown in said drawings, and I claim as my invention:

1. In a childs typewriting machine, the combination of a one-piece sheet-metal casing substantially U-shaped in cross-section and comprising a recessed top-wall and sidewalls, a transverse rear wall adapted to be secured to said top wall and said side Walls and a separate one-piece U-shaped 1 sheetmetal sup orting frame adapted to be received wit in said casin and supporting the entire mechanism an keys of the machine.

2. In a childs typewriting machine the combinationof a oneiece casing made of a sheet metal body su stantially U-shaped in vertical cross-section and comprising a recessed top-wall side-walls and a trans-v verse rear wall detachably secured to said top-wall and said side-walls and a separate one-piece U-shaped supporting frame of sheet-metal adapted to be received within said casing and supporting the entire mechanism and keys of the'machine.

3. In a childs typewritin machine, the combination of a one-piece s eet-metal casing substantiall U-shaped in cross-section and comprising a recessed top-wall and sidewalls, said top-wall and side-walls having -re-inforcing flanges along their edges, a

transverse rear wall adapted to be detachably secured to said top-wall and said side- Walls and carrying the guide-rails for the paper-roller carriage, and a separate onepiece sheet-metal supporting frame adapted tobe received withln said casin and su porting all the mechanisms and keys of t e machinefi 4. In a childs typewritin combination of a one-piece s eet-metal casmachine, the

ing substantially U-shaped in cross section and comprising a recessed top-wall and side-walls, said top-wall and side-walls having re-inforcing flanges formed along their edges, a type-carrying lever rest secured to said top-wall along the edge of the recess therein, a transverse rear wall adapted to be detachably secured to said top-walland said side-walls and carrying the guide-rails for the paper-roller carnage, and a U- shaped sheet metal supporting frame adapted to be received within said casin and supporting all the mechanisms and keys of the machine.

5. In a childs typewriting machine combination with t e casing, of a sheetmetal supporting frame substantially U- sha ed in vertical cross-section and adapted to e received within said casin and comprising a transverse member an two sidemembers extending forwardly from said transverse member, and an arcuate member, secured to said transverse member and adapted to form a bearing for the typecarrying levers of the machine.

6. In a childs typewriting machine, the combination with the casin of a metal supporting frame substantial U-shaped 1n vertical cross-section and adapted to be received within said casing and comprising a transverse member and two side-members extending forwardly from said'transversemember, all said members havin re-inforcing flanges formed along their e ges, an arcuate member secured to said transversemember and forming a bearing for the typecarrying levers. of the machine, and a U- shaped slotted member carried by said sidemembers and forming aguide for the keylevers of the machine.

7. In a childs typewriting machine, the combination with the casing, of a sheetmetal supportin frame substantially U- shaped in vertica cross-section and adapted to be received within said casing and comprising a horizontal transverse-member extendin laterally within said casing and two si e-members positioned at right angles to said transverse-member, all said members being provided with re-inforcing flanges, an arcuate member mounted on said transverse member and formin a bearing for the type carrying levers oft e machine, a U-shaped sheet-metal guide-member carried by said the side-members and provided with slots for the key-levers of the machine, and a shaft mounted in said sidemembers and supporting the spacing key of the machine, the shlft-keys being supported by said trans-, verse member.

8.In a childs typewriting. machine, in combination with a casing substantially U-. shaped in vertical cross-section, acne-piece open sheet metal frame adapted to be housed in said casing and comprising a transverse pieoe open sheet metal frame composed of a flat transverse member and two ugwardly inclined forwardly extending flat si e members hav' enlar d triangul said frame g a apted to support all the mechanisms and ke s. v
