Original application filed March 27, 1909,

1909, serial N0. 500,696.

To all whom it may concern Be it known that we, MARSHMAN W. HAZEN and OTTO PETERMANN, citizens ofthe United States and of the Republic of Switzerland, respectively, and residents of New York, county and State of New York, have invented certain new and useful mprove- The primary object ofthe invention is tov provide simple and eicient means mounted upon a carriage for feeding thepapcr to a stationary platen located adjacent thereto. I

A further object of tha-invention is to provide simple means whereby a part of the feeding means may also be employed as a platen.

With these and other objects in view, the

yinvention will be hereinafter more particularly described with reference to the ac-' companying drawings, which form a part of this speciication, and will then be pointed out in the claims at the end of the description. l

- In the drawings, Figure 1 is a longitudinal section, partly in elevation, of amachine showing one form of feeding means embodying our invention;v and Fig. 2 is a detail side elevation of one member of the carriage in which the feeding means is mounted.

The machine frame 10 may be of any desired construction and supported within the same are a plurality of brackets 11 to each of which are pivoted a plurality of kev levers -12. `These key leversare connected to op eratethe type-bars 13, and said typebars are provided with type-heads having one or more characters thereon, which, in their movement, engage the surface .of a platen 14.

Instead of the type striking the usual cylindrical platen, the type may engage a fiat surface, as 15, formed as a part of the plate-like platen 14, which extends transversely of the machine and is movable with the carriage 16, the said carriage having two frame members 17 and 18 to the former of which the plate or platen 14 is secured. The platen 14 may be curved for a greater part Specification of Letters Patent.

of its width except'at the. straightpart 15, formlng the printlng surfaces, and said platen may be secured to the part 19 of.`

the carriage frame member 17 or otherwiseA held as desired in a position so that the i paper or work may be readily passedV about the same, though instead of the type strik- 1ng dlrectly against ametal surface, a yielding surface or strip 20 may beprovide'd,

which strip may be so attached that it may be readily replaced in case of wear.

A roll- 2 1 corresponding to the usual platen roll may be journaled inthe framev member 17 of the carriage 16, and maybe;

provided; with the usualvfinger pieces'22,

by whichtlie 'rol1 may be rotated,ithe said finger pieces 22 being secured to the shaft of the roll 21, and to permit the roll and platen` frameto move vertically the carria e frame 2 member 18 is slotted where the sha through said member- At the rear of the roll 21 isa second smaller roll- 23, which normally `engages the roll 21,y and atthe -front of said roll 21 is a still smaller, roll24. `The shaft 25 of the roll 23 is held -in slotsv v26 in the yframe member l17 and has pe.

ripheral grooves at the ends thereof, and held to the ends of the shaft in such a way passes as to permit the shaft to rotate are they springs 27 which havek one end connected to levers 28. These levers 28, Fig. 2, are pivoted at 29, and have` their inner ends, as 30, adapted to be'. engaged by screws .-31,` soI that the tension-of the springs 27 may` bek varied and the roll 23. yieldingly held. against theV larger feed vroll 21. The rollk 24 issimilarly held to the roll 23, andhas the ends of its shaft, 32 held to slide and rotate inthe slots 33 of the carriage frame member 17, and connected to said shaft are the sprlngs 34 which are connected tothe levers 35, the latter being pivoted at 36 and normally forced in one direction by screws 37 to vary the tension of said springs. It will be seen that the roll 21 may be used as a platen by having the type engage the surface thereof instead of the plate 14, in which case the latter may be dispensed with. VWhile we show and describe certain `features of the machine other than the feeding means, we do not claim herein such features as they form part of our pendingapplication hereinbefore referred to or of other di'- visional and co-pending applications.
