which is a'rear view; Said roll is preferably of rubber or the like and is carried by a flanged hub 24 whichbears on the lefthand'reduced-end fportion 25 of a pin 26.

For the purpose of holding the pressure roll 23 out ofoperation atpleasure without affectingtheo eration' -of'the guide finger 19, I provide evices comprising a disk 29 havinga knurled periphery and secured eccentrically toa rota'ryand slidable sleeve or hub 30 which'bears onthe pin 26 and is ar- 'ranged betvveen the arm 1'5.- and the'h ub 24. g This diskor' eccentric device 29 is'adapted to erative or inoperative,positiomdetent de-' Qices 'are'prO ided.comprising asmall pin 31 i t; projecting radially from the pin 26 and -co- .coiiperate'with the: fac e of the guide 19 at one side of the slot 22.

will be'noted that the periphery against the finger piece .17, swinging the parts to the position shown by dotted lines .m Fig. 3. The upward'and rearward swing of the arm 15 and the parts sup orted there on is limited by the contact 0 the tail 16,

with the rear of the sleeve 6. In order 'to hold the arm 15 either down in operative or 'up in inoperative position, I provide a spring contrivance comprising a bow or leaf spring 36 which iscurved so as to bug or partly embrace the lug l0 and has its forward end secured to a pin 37- projecting laterally from the arm 15; The rear end of the spring 36 is hooked into a transverse groove orslot 38 out in the rear side of the lug 10;

The inherent tension of the spring 36 is such that its ends tend constantly to approach By reference to Fig. 3 it will be note t K when the paper finger is inoperative position an imaginary line joining the ends of the spring 36 will be below the pivotal center a out which the arm 15 turns. In other words, the tendeneyof the spring 36 is to swing the arm downward and maintain the pressure rolls 23 and guide finger l9 in-cooperation with the platen. It will be under- -stood that the spring 36 being stronger than l the coiled springlS willcoinpress the latter sufiiciently to enable the pressure 11 23't0 -.co6perate properly with the-platen 'and to maintain the guide'finger 19 under proper ,.piessure. When the paper finger is swung mupward out of operation to the dotted line position of Fig.3, thespring 36 will be ex- "panded or spread and an imaginary line It will be apparent that when it is desired. to adjust the eccentricdevice 29 it is preferable to raise the paper 'finger temporarily will move the guide finger 19 away from the eccentric 29, thus enabling the eccentric to be turned freely to its" operative position without contacting with the arm.l9. The parts -2.9.'-and 19 will engage only after the restoration of the paper feeding devices to -normalposition and the compression of the spring -18 by-the spring 36-.
