PAPER GUIDING ARRANGEMENT FOR TYPEWRITERS AND LIKE MACHINES 2 sheets-shew 2 Filed Nov. 4, 1927 Patented Nov. 26, 1929 UNITED STATES,

PATENT arm-ca PAUL KKPPLER, OI DBBSDEN, GERMANY This invention relates to paper (guiding arrangements for ty writers an like machines. Heretofore it has been usual to guide the paper around the roller platen by means I of two abutting plates, one of which is a bent plate shaped to t the roller platen and usuall of thm nickellated metal and the other a litter substantia y flat and stron -er plate obliquely and upwardl directed an usually lacquered. The flat p ate is also partly removable or movably attached. In order to reduce the weight of the flat plate and yet keep the t written sheet clearly visible and in order a so to prevent the sheet from catchw ing in the shift mechanism and margin stops of the typewriter the oblique flat plate is usually extended by the addition of a so called paper holder of light construction.

In ortable typewriters or like machines inten ed to be contained in a case of the smallest possible dimensions, the above described aper uiding arrangements cannot be emp oyed, creases the dimensions of the machine. It is usual therefore in portable typewritersand the like to omit the flat plate completely and to attach a paper holder, which can be erected into position for'use to the bent guide plate. Apart fromthe fact that such type- 33 writers look incomplete and require several knobs for manipulation, the typewritten sheeitsd are not sufficiently supported and e The present invention has for its object to overcome the aforesaid drawbacks and for this pur se the three parts forming the paper gui e, viz the curved guide plate, the paper rest and the paper-ho der are so jointed or interconnected togetherv by rmeans' of hinges or pivots situated below the path of the paper that the-paper rest and holder can be folded in unison around the roller platen. By this arrangement an eflicient paper guiding arrangement is provided without the machine requiring to e of larger dimensions than usual. Moreover according to the inven Y tion the paper holder which is formed of .wire is provided with a'central inward bend or ton e, whose tip fits beneath the outer edgp o the paper rest and'thus provides for TYPEWBITEBS AND LIKE MACHINES 231,008, and in Germany December 24, 1926.

efiiciently guiding narrow sheets without any obstruction.

In order that the invention may be more clearly understood, reference is hereinafter made to the accompanying drawings illustrating a preferred construction of my invention and whereon:

Fig. 1 is a fragmentary side view of the machine partly in section and showing the case dotted.

Fig. 2 is a plan view of the paper guide.

The roller platen 1 and the paper feed rollers 3 and 4 are mounted as usual on the carriage 2. The type 5' is of the front stroke type, that is to say, it strikes the roller platen 1 at a point in front of the central vertical plane of the platen. It will be apparent that the rear edge of the carriage 2 and machine frame 6 would determine the rear limits of the typewriter in the absence of any protruding paper guiding arrangement.

' In the construction shown the paper rest 7 ecause this materially in is intepconnected with the usual curved guide plate 5 by hinges l4 and is pivoted to the carriage 2 by means of end journals 17. The paper holder 8 is pivotally mounted by its doubled ends 10 in a beading 11 formed at the outer edge of the paper rest 7. By this construction-the paper holder 8 and paper rest 7 can be folded into the position indicated in dotted lines in-Fig. 1 so that they do not in the least or only to a very slight extent protrude be 0nd the rear limit of thetypewriter formed y the carriage 2 the margin stops 9 and the machine frameG. The carrying case 16 may then be given the shape likewise shown in dotted lines.

It will of course be understood that the journal pins 17 might be replaced by continui I ous hinge pins. lhe paper rest 7 in the construction shown is connected with a stop 18 which is mounted on the journal pin 17 and hasa projection which rests against the CHI. riagie 2 when said paper rest is in operative position. The arrangement herein described is also very conveniently adapted for the manipulation of the margin stops 9, these being readily accessible after folding the paper holder 8 and paper rest 7 over-the roller platen 1.

The paper holder 8 is preferably of substantially M-shape as shown in Fig. 2 so that it is of a springy nature and its bent ends 10 can be readily inserted in the beading 11 of the paper rest 7 by allowing the ends 10 to spring apart. Similarly, by contracting the wire paper holder 8, its ends 10 can be readily withdrawn from the heading 11 of the paper rest 7. The paper holder 8 is usually retained in the machine and is merely moved into the dotted position when the typewriter is not in use or is cpntained in its transport case.

It is inadvisable to construct the paper holder 8 of sheet metal and to hinge 'itto the paper rest 7 on account of the increased weight which this would involve. It is therefore usual to construct the paper holder of wire or light rods, but such holders as heretofore constructed have usually either been insuficient to properly support wide paper sheets or obstructed the proper passage of narrow sheets or post cards. The wire paper holder 8 illustrated in the drawings obviates both these faults inasmuch as it extends almost over the whole breadth of the paper sheet and is also provided with a central support or tongue 12 for narrow sheets or post cards, the tip 13 of the central tongue resting behind the heading 11 of the paper rest 7, so as to prevent any obstruction to the gliding of the sheet or card'from the paper rest 7 to the paper holder 8.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, ll declare that what I claim is 1, Paper guiding means for typewriters and like machines having a roller platen com prising a curved paper guide plate, a paper rest hinged to the guide plate so as to be foldable against the rear of the platen and a paper holder hinged to thepaper rest so as to be foldable downwardly and forwardly over the platen. 1
