/l M/Q F. METZGER TYPEWRITER Filed Jan. 24, 1938 Feb. 23, 1939 Patented Feb. 2s, 1939 UNITED; STATES PATENT OFFICE l '2,146,570V l TYPEWRITER' Fritz Metzger, Chicago, Ill. Application January 24, 1938, serial 10.186.566

z claims.r (C1.- 1o1'-1o3) A lVIy invention relates to a type-writer, and ,es-l

pecially to a type-writer which may be operated with equal Afacility by children vas well as by adults. l f f Devices of the kind specified are known, but they are 'either expensiveor so complicated in operation as to make them undesirable.

It is, therefore, an object of my invention to provide ya compact and portable type-writer Whichis'b'oth simple to operate and so inexpensive that it may be used by everyone.

Another object of my invention is to provide a type-writer which is simple enough for children to operate, and yet may be used in business or for printing signs, legends, and the like. Y It is still another object of my invention to providey a type-writer in which ink is applied tothe type while the device is being used.

' in the accompanying drawing, in which:

Fig. 1 is a front view of my device shown in y folded position.

Fig. 2 is a plan view of my device shown in folded position.

' Fig. v3 is an. end view of kmy device shown inv folded position.

Fig. 4 is a fragmentary plan view of my device opened, and in operating position. Fig. 5 is an enlarged cross section of the typewriter in closed position.

Fig. 6 is an enlarged section view on the line 6-6 of Fig. 4, and

Fig. 7 is an enlarged perspective view of a fragment of the type-bar.

. Referring to the several views in the drawing,l the device comprises a pair of rectangular casingsV I in the form of channels closed at the front and rear by end walls II and I2, constituting angle irons and extending beyond the inner side Walls I3 and I4, and overlap to be connected by a hinge joint I5, so that the casing may be arranged in flat position to be in horizontal alignment, as shown in Figs. 4 and 6, or folded into compact arrangement, as shown in Fig. 5.

In the casings are arranged ink pads I6, which y stop short of the ends of the casing, but if pre- An inverted channel I1, constituting a platen, is arranged parallel to the side walls of the casing and secured to the inner ends of the end walls II, I2 just below the hinges I5.A

A type bar I8 is provided with blocks I9, having letters, numerals or other indicia I9a, thereon. TheV side of the type bar contains Ialso letters, numerals, or other indicia 2|, to correspond with the-appertaining indicia on the blocks.

When the rdev/ice is in folded or collapsed condition, the type bar is inserted between the platen I1 and the protruding end walls of the adjacent casing.

The type bar I8 has a depression 22 at each end into which is received a ball protuberance 23, so that the type bar is rigidly held in place and forms with the device proper a compact unit.

In use, the type bar is removed, a sheet of paper 24 is threaded through the spaces defined by the platen I1 and the casings Il, whereupon the casings are unfolded, so that the paper overlies the platen I1.

'I'hen the type bar is held transversely to the longitudinal direction of the casings and lowered until a selected letter or numeral is in alignment with that portion of the paper which overlies the platen I1, as is clearly shown in Fig. 6.

Attention is called to the fact that the blocks are spaced from one another and so arranged that, upon a block being in typing position, the edges of the casing side Walls are received in such spaces, so that typing along the paper will always occur along a straight line.

It is also noteworthy that some of the blocks, while printing, enter the casing and become inked While the typing is carried out.

The arrangement of the type bar to be slid between the platen I1 and the end walls II, I2, when the device is in compact form, prevents opening of the device until the type bar is first removed.

The casings, when folded, have their open sides close together, so that their inking pads are protected from contamination and against drying out, and also facilitate handling of the device, as the fingers of a person do not come in contact with the pads.

While the drawing shows a preferred embodiment of the invention, numerous changes and alterations may be made without departing from the spirit of the invention.

I, therefore, do not limit myself to the details or particular arrangement orconstruction, as shown, but wish to claim the invention as broadly as the state of the art permits.

.W anni I claim:

1. A typewriter, including a casing having an ink pad, edges on said casing projecting above the level of said pad, a platen secured to said casing and adapted to hold a sheet of paper thereon, and a type carrier having serrations in spaced relation to receive said casing edges and engaging with a single letter the paper at constant distance from said casing.

2. A typewriter, including a casing having an ink pad, edges on said casing projecting above the level of said pad, a platen secured to said casing and adapted to hold a sheet of paper thereon, and a type carrier having serrations to receive said casing edges and engaging with a single letter the paper on said platen and with a plurality of letters said ink pad.

3. A typewriter, including acasing having an ink pad, edges on said casing projecting above the level of said pad, a platen secured thereto Yadapted to hold a sheet of paper thereon.. and a type carrier having serrations to receive the edges of said casing and engaging the paper at constant distance from said casing and engaging with a plurality of letters said ink pad.

4. -A typewriter, including a pair of hingedly connected casings having ink pads, edges on said casings projecting above the level of said pads, a platen interposed between said casings and secured thereto, said platen holding a sheet of paper, and a type carrier having serrations to receive the edges of said casings to thereby align a single letter with the platen.

5. A typewriter, including a pair of hingedly connected casings having ink pads, edges on said casings projecting above the level of said pads, a platen interposed between said casings and secured thereto, said platen holding a sheet of paper, and a type carrier having serrations to receive the edgesl of said casings to thereby align a single letter with the platen and a plurality of letters with said ink pads.

6. A typewriter, including a pair of hingedly connected casings having ink pads, said casings complementing one another in closed position to form a box structure, a platen parallel between said casings and secured to one of said casings, and a type bar adapted.' to imprint with a single letter on said platen, said platen being spaced from said casings when closed to afford a slot for threading a paper therethrough.

7. A typewriter, including a casing having pad, a. platenisecured to said casing and adapted to hold a sheet of paper thereon, a type carrier adapted to engage with a single letter the paper, and means on said type carrier engaging said casing to cause the successive imprints of the type carrier yto occur on a straight line on the paper.
