IMPROVEMENT iN MACHINES'FOR;'PcNcHiNG PAPER FOR Triton/iPHS..`
Specifieationnforniing part-ofI-Jetters Patent No. Lll-,klated Deeelfnher l2, 1865.-
To all 'whom it may Gomera:
Be it known that I, MARsriALL LEFFER'rs, f the city and State of New York, have invented, made, and applied to use a certaiirne'w and useful Improvement in Means for Punchpart of thisspeciati'on, wherein-'- u n v Figure 1 is a front elevation of roy-punchingmachine, and Fig. 2 is a section at the line a: a: ofFig.l.
Similar marks of reference denote the same. parts.
The present invention isan improvement npto J ehn P. Humastoii-nvthe 8th day of September A-.Df-land' a referieeisfhereoy made 1 to the said patent for a more complete descriptionof anyr ofthe parts that may he shown on thev drawings and not described in detail hereployed as in the aforesaid Letters Patent." The machine of the said .Huinast-en was actuated by a pairof treadles that were operated bythe feet in unison with the keys, so as to rotatev thetypewlieel and punchthepaper with the perforation or group of perforati-ons representing theletter on the key struck. ln this niat'weeu thetime of forming each letter, and
simultaneously with the projection of a pin corresponding to the letter struck, which latter arrested the rotation of the typewheel while the punching took place. lt is difficult to and hence the machine was sometimes injured by the parts not being n their proper position when thekeys were struck.
rlhe nature of my said invention consists in;
ction mechanism, whereby the machine is by progressive rotation of the principal'parts in one direction, and withoutliability to injure airy of the parts, and the operatolhas oulyto strike the keys lfor composing a message, the continuous rota y motion being derived from any desired source 5 but the operator may, by a v volve with the said Wheel and shaft, as heref inafter showinunti'l-oii of the keysEis struck,
allowing its icorresponling pin, d, to project and'take thel arie t', stdpping. the motion. of B andB, while tliefrl'let bf'paper is punched by the punches orcutters a in tile 'box A, 4as in the aforesaid patent.A A band, l, i's'provided,

can revolve between the. disks 6 and 7 when the urns t is arrested byone ofthe pins d" being projected when the key Eis helddown; hence the type-wheel B willvreinain quiescent while the punching takes place, but so soon as the key Eis released the type-wheel B and -arm t' will ily around until arrested by another projecting` pin,and the movement will be coniplete in each instance asv soon as the key is re-.
leased; hence a second key can be struck inetant-ly, and so on. y
Instead of vthe shaft 9" receiving an intermittent oscillation, `i' give to the same a progressive rotation from the revolving frictionwheel 2, so that each time `a keyv is' vstruck an escapement .is actuated, that allows the friction between said wheel 2 and a disk, it), at-
tached to said shaft g, to give to said. shaft one coml'ileerota-ation to perform the operation of 'feeding the paperfbyalrejever j actuating the cutters (L bythe le\er\d,\er\niovi.ng -the clamp for saidcutters @by the cani Z, furthe same purpose and in the saine relative order. as in the aforesaid patent; but the cams m', l, and l' are to be shaped so as to give the proper movement :at the right time bythe entire rotation of thcshal't g' instead 'of its oscillation,
as before.
