To all whom it may concern:

Be it known that we, JOHN. SELLERs BAN- oRoFrand MAURITZ O. INDAHL, citizens of the'United States, and residin at Philadelphia, in the count of Philadelp ia and State of Pennsylvania, aveinventedcertain new and useful Improvements in Keyboard Perforating-Machines; and we do hereby declare the follewing to be a full, clear, and exact description of the same, reference being had to part of thisspecification, and to the figures and letters of reference marked thereon.

- effective ,a; insure a full action 0 This invention relates to a keyboard actuatingmechanism for record strip, perforating and other machines employing a plurality of punches or operating devices controlled from a bank of keys, and it has for its objects to provide a system whereby the characters may be distributed on the keybank according to any desired plan, irrespective of the space value or other characteristics incident to the relative arrangement of the punchestor other devices; to render the key movement ,easyand its action rompt and Ithe devices designated-and controlled by each key and prevent interference; and, generally, to improve the construction and arrangement of the machine as a whole.

To these ends the invention consists in the novel combinations, constructions and arrangements of parts and mechanisms hereinafter fully described, the novel features being pointed out in the appended'claims. I

i In the accompanyin drawings illustrating apreferred form of em odiment and adaptation of the said inventionFigure 1 1s a side elevation, partly in section, of a portion of a record stri perforating machine with the new key action applied thereto. Fig. 2 is a front elevation of the punch actuating mechanism including the punch bars, punch a'ctuator frame, the motor therefor and the system of interponents. Fig. 3 is a detail view of a portion of the line measuring mechanism with the stop bars for admeasuring its advance movements. Fig. 4 is a detail 'view showing the elements of the permutathe accompanying drawings, forming a.

paper feed, represented by the paperetower 1 and actuating bar. 2; the line measurin mechanism, represented by the units wheeI 3, units-rack carrier 4, stop-bars 5 and motor cylinder 6; the indicator mechanism represented by thejustification-scale carrier 7 and its gearing 8; and the perforating mechanism represented by the series of punch-bars 9.. The escapement of the line measuring mechanism may be actuated by a cam lever 10 and the resetting devices by a special key and valve after the manner described in Pat-- ent N 0. 828,449 of August 14, 1906, the 'ustification indicator being connected wit the line measuring mechanism as in either of the before mentioned patents.

As an aid to a clear understanding of the present improvements, which have to do with the actuating system therefor, it may be well to state that the commercial machines constructed under' the patent hereinbefore mentioned are each equipped with thirtyone punches, for producing the perforations or signals in the record-strip, and. with thirty two punch bars,

being without a punch. Of these punch bars, sixteen re' resent space value, hence are coupled to tffe of this number one has nopunch, one corresponds with the keys, and fourteen represent different degrace of adjustment for the die-case. This series of punch-bars is herein denominated the space value group. Of the remaining sixteen punch bars, fourteen represent degrees of adjustment for the diecase in a direction transverse to the'first and two correspend to the justification-designation signa s.

In forming the type-signals in the record strip it is necessary that at'least one unch bar of the space-value group shou d be one of the latter justificatlon-space key or NDAHL, OF PHILADELPHIA, PENNSYLVANIA, CHINE COMPANY, OF PHILADELPHIA, PENN"- series of stop-bars 5, and

brought into action, to impress the normal sipace-value of the type upon the measuring evices, and in most instances two punch bars are required, representing degrees of motion on intersecting lines forlocating the matrices of the die-case o posite the casting point, one of said punch-Ears being selected from the space-value roup and the other from the non-space-va ue' group. The selection and operation of the punch bars, to roduce the great variety "of signals desired is effected by the actuatingand control system intermediate the punch-bars and the keys, each of the latter representin a different type and producing the signa corresponding thereto.

The punch bars of the space value group are each provided with pins 11 engaging a lever 12 connected to one of the stop-bars 5, and as the motion of the latter is thus reversed, as compared with Patent No. 654,115 the bars 5 are notched, as at 13, for the passage of the units-rack stop, the portion above the notch intersecting the path of the unitsrack when the punch-bar is elevated.

Located in proximity to and supported to reciprocate parallel with the series of punchbars is the punch actuator 14, represented as a plate formed with two transverse ,slots or openings 1516, in different planes and provided with cylindrical or other shaped guides 17 Working in bearings on the frame. The upper guides 17 are bored out to receive limiting screws 18 while the lower guides terminate in pistons 19 working in cylinders 20, the latter constituting the motor. Both cylinders communicate through pipes 21 wlth the port 22 of a valve chest 23, Fig. 5, the latter containing a slide valve 24 and exhaust port 25. The actuator 14 is provided with lugs 26 for engaging the paper feed actuator bar 2, and the cam lever 10, so that at each reciprocation the paper feed and escapement of the measuring mechanism will be operated.

Each punch bar 9 is provided with an offset or'stud 27 projecting within and normally occupying the upper section of one of the openings 15.16 in the actuator 14, and opposite each punch-bar is an interponent 28 or 29, held normally removed from the actuator but adapted to be interposed between the latter and the stud 27. The slots or openings 15 and 16 in the actuator merely represent intervals between two opposite moving surfaces, the one actin directly upon the studs 27 of the punc -bars, to move them in one direction, and the other acting through the interponents, when in position, to move them in the opposite direction. A single slot presenting two oppositely located barswould suffice for this purpose, but for convenience and economy of space two slots are preferred of which the lower 15 receives the studs 27 of the space-value versa.

group of punch bars, andthe upper 16 the studs of the non-space .value group, or vice To distinguish the two groups of interponents those of the space-Va ue group are numbered 28 and those of the other group 29.

' The keys 30 of the keybank are in the form of bell-crank levers pivotally supported on rods 31 'in an inclined frame 32, their horizontal arms carrying finger pieces 33. For convenience the keys are disposed in lines and columns although any other 81-- rangement or relative disposition is permissible. Beneath the keyframe 32 is arranged a series of longitudinally movable bars 34 properly spaced and supported and guided at one end on the frame 35 and at the other upon a series of pivoted links or tumblers 36 mounted upon a shaft 37. The bars 34, one for each key, are preferably formed in two longitudinal sections, united, as by a rib and seat 38 to cause them to move to ether,

the upper section provided with a ug 39 opposite its keylever and the lower section with a permutation or selecting lug 53.

Beneath and parallel with the series of key-bars 34 is a series of interponent bars 41, one for each interponent 28, and connected to the latter through a pin 42, lever 43, link '44 and lever 45. The interponent 28 -is formed upon or carried by one end of a rod 46 resting'upon a cross bar 47 attached to frame 48,'the opposite end of said rod being pivotally attached to lever 45. A spring 49 may be attached to the lever 45 to retract the latter and withdraw the interponent from enga ement with its stud. Extending transverse y of and between the two series of interponent bars 41 and kevbars34 is a series of pairs of transmitter bars 50 equal in number to the interponent bars; Each bar 50 is mounted upon a rock-shaft 51 and is received between shoulders 52 carried by one of the series of interponent bars. As thus arranged each key bar represents-a key .and each interponent bar an interponent,

hence to transmit motion from any key to any interponent it is only necessary to provide its key bar 34 with a shoulder or projection 53 in position to engage one of the transmitter bar 50 coupled with the interponent bar 41. of. the desired interponent.

The selection and operation of the interponents 29 of the other, a non space value group, is effected through a second series of ey bars 54 provided with permutation shoulders 55.- Each bar 54 is pivotally con' nected to one of the links or tumblers 36, so

as to partake of the movements of its key bar 34, and its shoulder 55 is in position to engage one of a transversely arranged series of transmitter bars 56 each of the latter in turn engaging a lug or shoulder 57 on one of a series of interponent bars 58. In this case the interponent 29' is carried by a rod 59 61 and engagmg a lever 62 to sesame one key, and each interponent bar 58-to one transmitter 56, so that by properly locating its permutation shoulder 55, any key maybe coupled with any one ofthe series of interponents 29. A laterally movable bar-64 provided with a spring 65is arranged in posi-' tion to engage a shoulder, 66 on each keybar 34, when the latter is moved by-its key, and serves to cushion the key action as Well .as to insure the return of the key bars.

The mechanism as thus far described is cometent to place any oneor more of the punch: ars in o erative connection with the actuator, by t e de ression of a single key, i1're spective of its ocation in the keybank, and it remains to be seen how the selected punchbars are moved to perforate-the stri and opcrate the connected mechanism. 'l he interponents rest normally in close proximity to the actuator 14: so that a very slight move,

ment will bring them intooperative relation to the actuator and punch-bars.

Each of the second series of key bars 54- carries in addition to its permutation shoulder 55, a shoulder 67 engaging'a transmitter 68, -the latter in turn acting upon a shoulder Y 69 on bar 70 to which is pivoted the motor trip' bar 71. Thus when any key is depressed motion is transmitted to the trip bar 71 whose rear or free end passes through the opening in actuator 1.4, and rests upon the lower bar so that it will artake of the motions of the actuator. *VV hen at rest the end of trip bar 71' stands opposite a shoulder or lug 72 on one arm of a pivoted lever 73, the other arm whereof carries an adjusting screw 74 engaging the stem of slide valve 24.

Above the tri bar 71 and intersecting its path is arran ed a pivoted latch 75 provided with a shoul er 7 6 normally resting upon a shoulder 7 7 on lever, 73 but adapted to drop in front of said shoulderwhen .the lever is moved to uncover the ort 22. Thus whenever a key is depressecl toadvance its interponents into engagement with the actuator, the trip bar operates through lever 73 to shift valve 24 and uncover port 22, thereby admitting pressure in the motor cylinders to advance the actuator and the selected punch bars. At the same time the latch engages shoulder 77 on lever 7 3 to retain the valve in its open position after (pressure upon the key has been removed an the key returned to initial position. As the actuator advances it carries the trip bar 71 above the lug 72 into engagement with the latch 75 and u on the completion of the stroke, disengages t e latch from its retaining shoulder 7 7 thus releasing the shifting lever 78' so that the valve to move under the Witythe actuator,-

It Will be noted that bythis arrangement the. key 0 crates merely to couple the selected punchbars with the motor-hand. inau urate the action of the latter by setting :its control valve; that. the motor isautomatically disconnected or "thrown out of action-by: the movement of a memberdriven thereby; to and that the movement-0f the actuator automatically-moves =the1;trip out of en agement with the valve lever by lifting-it a ove the lug thereon. This is-cohducive to quick and easyaotion of the keys and insures a full stroke of the punch bars; moveover, the movement of'the actuator inaugurated by'the depression of a ke interposes a barrier to the movement of a l interponents. other than those controlled by :the depressed key, thereby preventing interferences should another key be depressed,- accidentally or intentionally before the corn-v pletion of the punching operation and the return of the actuator.
