To all whom L may concern: f
Be it known. that I, ARTHUR J. WADs- WORTH, a citizen of the United States, residi'ng at Washington city, in the District of Columbia, have invented a newv and useful Improvement in Keyboard for Monotype Performing-Machines, of which the following is a speciiication.

his machine is designed to produce'perforated record-strips or controllers Which are subsequently used to govern other mechanism, such as type-making machinery in the production of printing-type. f

My invention relates to the `keyboard of this machine, and has for its object to simplify and cheapen the construction of the pneumatic features, to render the touch more sensitive, and reduce liability to derangement, as well as to give more convenient access to the parts. To this end I make the com ressed-air chamber in the form of a marginal trunk entirely .outside the bank o'f keys and surrounding the same on three sides, arrange the valves in this trunk, Vand operate them by two series of rock-shafts, one crossing the other at right angles and each rock-shaft being provided with a seriesy of crank-arms, the crank-arms of the rock-4 marginal compressed-air trunk and transmit two pneumatic blasts throngl suitable pipes to two corresponding punc tons,4 all as hereinafter more-fully described -operat'ing pis- I with reference to the drawings, vin Whichi Figure 1 is a plan View omy keyboardbase, the keys and upper parts being re- 2 is a side view, partly in seceyboard. Fig. 3 is aperspective Yiew of one corner of the marginal compresssd-air trunk, partly broken away. Fig. 4 is a sectional detail showing the connection between the compressed-air trunk of the keyboard .and one of the punch-operating pistons. Fig, 5 is a sectional detail showing a moved. Fi
modiiied form of the pneumatic valve.
In the drawings, Fig. 2, C represents the keys, which lrise in succession away from the position of the operator like the keys of a type-writer. Thel keys4 bear upon their youter faces the letters and characters which they re resent, and the posts of the keys descend At plate D.
Each key-post'has on its lower end a c, 3,- that rests upon the s tonl ordis f h 1 i of a. air o rig t-angu' ar crank-arms a and b, hired i seriesof rock-shafts.. The positiQDSQf, these oughand are guided by a deck-l r oo' toa corresponding key-buttons in relation to the crank-arms are indicated by the dotted circles in Fig. 1-, where the two series of crank-arms a and b may be seen projecting toward each other.
A A A, &c., represent a series of parallel rock-shafts, each of whichbears a series of crank-arms c a a, rigidly connected to it.
B B B, &c., represent a series of parallel rock-shafts lying in a plane beneathl the rockshafts A and crossing the same at right angles. Each rock-shaft B has also a seriesof crank-arms t b b, which are bent up slightly at their 4free ends, as seen in Fig. 2, so as to lie in the same horizontal plane with the crank-armsl a of the other series of rockshafts. The free ends of the two crankarms a and b of each pair approach 'each otherso closely as to nearly intersect and allow their outer ends to lie beneath the same key-button c of a key, as seen in Fig. 3, so that when any key is depressed it will act both upon the arm a and arm b of any pair and so rock the two shafts A and B, to which they are respectively attached.
The outer ends of the rock-shafts A and B are journaled in a marginal frame T T T2, i
which. surrounds the bank of keys-on three sides and lies outside of the same, as seen in Fig. 1 on its upper side to form an air-trunk in which is maintained constantly a supply of compressed air by means not necessary to'be described. The top t of this trunk is remov-l able tor the purpose hereinafter described. Through the bottom. of this trunk-frame are formed a series of holes o, Fig. 4, each of which communicates with one end of a passage-way or pipe E, leading to a small cylinder F, in which plays a piston e, which is raised and lowered by ablast of air and which piston in its movement actuates one of the punches which perorates the paper record-strip. Only one of these connections is shown in Fig. 4; but it will be'understood that there is one for each rock-shaft in both of the series.
At the point where'each rock-shaft enters the air-trunk it is provided with a rigidlyconnected flap-valve o or fv, which rests above and closes the top of the air-passage o andis held tightly down thereupon by pneu- When, however, the rock-- matic pressure. shaft is rocked by a depression of a key, this flap-valve is raised and the compressed air in the .trunk T T T2 passes down through the outlet 0 and acting through'the pipe E lifts the piston e and rock-shafts are simultaneous y rocked by the depression of any key intersecting va pair of crank-arms brand b it will be remembered that two punches are simultaneousl ated to perforate the paper stri in t e predetermined way to indicate t e letter or character to be punched, the relative" posi- This marginalframe is m'ade hollow with'both series of operates a punch. As twov oper- 3, and 4,*.as this makes a quick it without the need of springs. I haveV shown, however, coil-springs s on' the rockshafts, which may be of value in several ways. Thus, for instance, in Fig. 5 I show instead of a flap-valve a rotary plug-valveoz, turningin a seat in the trunk, and with this form of valve where the air-pressure will not eiiiect .the closing the spring 'would be essential. The springs,
more tightly closed or the spring might be arranged withthe Hap-valve, so as to partially antagonize theair-pressuraand thus permit me to use 4a high pressure of air for punches and yet enable the` .I keys to open the flap with a light and sensioperating the moreover, y 4may be of l value with the flap-'valve either to hold them tive touch. .I therefore do not confine myv invention to the' particular construction and arrangement shown and described either of.
the valves or the Aother parts of my keyboard, as they may be varied in many rspects Without departing from my invention as expressed in the claims.
'As shown, two side .trunks T T2 are used for the B series of rock-shafts. This is merely to enable me to more wideljyf'separate the valves v', and thus get more room to make the necessary connections for the airpipes below, for by putting the side valves alternatel sides may be more widely separated.`

but is merely employed to bring to certain of X the'lower keys the same resistance as'the' others, so as to 'give a uniform touch.
