To all whom, it may concern:

Be it known-that I, JOHN SELLERS BAN- onor'r, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful. Improvements in Perforating-hriachines and I do hereby declare the following to be a full, clear, and exact description of the same, reference be: ing had to the accompanying drawings, forming a part of this specification, and to the figures of reference marked thereon.

This invention relates to an improved line measuring and indicating mechanism for perforating and other machines, and is more especially designed for use in connection with the keyboard-perforator of Patent No. 654,115 as a substitute for the actuating and controlmechanisms therein illustrated.

The invention has for its principal objects to simplify the mechanism and render the same more readily accessible for adjustment.

ing devices as a gage instead of as a motor in effecting the adjustments of the indicator element, and generally to reduce cost of construction and increase durability and efliciency in action.

With these ends in view the invention consists in the construction and arrangements of parts hereinafter described, the novel features being set forth in the claims.

In the accom anying drawin s, illustrating the preferred form of embo iment, Figure 1 is afront elevation of a keyboard perfoapplied. Fig. 2 isa transverse vertical section on the line no :10, Fig. 1, inclu'dinga portion of the base and keyboard. Fig. 3 is a rear elevation, partly in section, of the line measurin and indicator mechanism. Fig. 4 is'a si( e elevation of the escapelnent and control devices of the unitswhecl.

Fig. 5 is a View in perspective of a portion ofthe escapement devices including the holding-pawl, unitsrack carrier, and the lifting-cam. Fig. 6 is a sectional view of the release-cylinder for the space-counter or pointer-adjusting mechantailed description of the construction and operation of the machine as a whole.

For purposes of identification it will suffice to mention that 1 designates the series of valved finger-pieces; 2, the ressure-chamber; 3, the punch-levers; 4, t e punchlever cylinders; 5, the punch-bars; 6, the rocking frame overlying and actuated by each punchparts in the lever and controlling the paper-feed valve;

7, the units-wheel;'8, the motor-cvlinder; 9, the motor-return cylinder; 10, the motorrack; 11, theunits-rack; 12, the units-wheat locking pawl, 13, the units-rack carrier; 14, the series of stop-bars for measuring the advance ofthe units-rack; 15, the justificationscale or chart-actuating pinion; 16, the shaft carrying the justificatiomscale; 17, the justification-chart; 18, the movable pointer; 19, the space-counter or pointer-adjusting mechanisni; 20, the spaee-counter-holding pawl; 21, the line-rack; 22, the line-scale, and 23 the paper-tower and die-plate support.

As heretofore constructed, the machine was equipped with a reversing-shaft located within the base and provided with two valves controlling the motor and motor-return cylinders and two arms controlling the unitswheel and space counterrretaining pawls, said reversing-shaft being in turn controlled by the valve of a resetting-key through a piston, cylinder, and return-spring. Moreover, the stop-bars were provided with projections acting upon a pivoted blade or wing on the units-rack carrier for elev ating the 111llti110l1 and locking-pawl, while the justificatitm' chart-actuating pinion was driven from the motor-rack through a iekup which com pelled the chart and its Q riving mechanism to follow the movements of said motor-rack during a portion of its traverse. In the main u'facture and practical use of the machines as thus constructed numerous defects were developed and among othersv difficulty of adjusting and maintaining the,reversing-shaft and its connections in working order, due to its somewhat complex structure, the multiplication of valves and ports, the necessity for coordinate adjustments as between the several elements, and the inaccessibility of the parts.

perfect action of the escapement devices and resulting in mutilation of the units-wheel, and the inertia incident to the quick starting and stopping of the justification-scale and its carrying mechanism tended to rupture the latter and to impose additional labor upon the measuring devices. To overcome these and other defects incident to the prior construction, the elements above mentioned have been dispensed with and the new system or form of control mechanism about to be described has been provided.

In or upon the base is formed a valve chest or chamber 25, Figs. 7 and 8, communicating through a duct 26 with the pressure-chamber 2 or other source of pressure and containing a port 27, leading to the motorcylinder 8, a port 28, leading to the motor-return cylinder 9, and an exhaust-port 29, leading'to atmosphere. A valve 30, connectedto the resetting-key 31, controls the ports 27, 28, and 2%), so that when at one ext-rem. of its movement or in normal position the valve will cover and establish communication between ports 28 and 29 and uncover port 27, thus admitting pressure to the motor-cylinder and opening .the exhaust to the motor-return cylinder,

and when the valve is actuated by the key it will reverse conditions, opening the exhaust to the motor-cylinder and admitting pressure to the motor-return cylinder, lthercby reversing the motion of motor-rack and restoring the parts to initial or starting position.

' For convenience of adaptation the reset-- ting-key 31 is preferably located to one side of the bank of keys 1, Fig. 1, and the valvechest, formed partly in the side wall 32 of the base and partly in a bar or block 33, secured thereto, as shown in Figs. 7 and S, and the form of valve preferred is of the D typo, comprising a circular cup-shaped structure sliding inconta'ct with the face of the valve-chest and pivotally attached to the valve-stem, so to be free to rotate, and thus insure proper seating. Other forms or types of valves may, if desired, be substituted, providing direct control of the motor and motor-return cylinders by the rcsettin g-ltey retained but the resetting action cannot be eil'cctcd until the locking or holding .pawls of the unitswhcel and the space-counter have been released. To accomplish this, the liftingdink A tendency to racing on the part. of the units-wheel was developed due to im.

34' is cut oil above the top surface ol the base and bent to one side, as seen in Figsv .3 and 5, so as to bring its end in proximity to the tail of the space-counter-holding pawl 20. Bolted o'r otherwise secured to the frame is a cylinder 35, Figs. 2, 3, and 6, containing a loose piston 36, carrying a plate or arm 37, provided with a pin 38. The head of this iston is located below and in line with the end of lifting-link 34-, and the pin 38 stands in line with the tail of pawl 20, so that when the piston advances the two holding-pawls and 12 are withdrawn to release the spacecounting and line-measuring devices and permit their return to initial position. The admission and withdrawal of pressure in cylin- .der is controlled by valve 30 of themotor and motor-return cylinders, as by connecting its port 39 with the pipe leading to the motor-return cylinder, so that the thrust of the piston and release of the holding-pawls will take place slightly in advance of the return movement of the motorrack, lost motion and the throttled escape of air from the motor-return cylinder favoring such action.

As the lifting-link 34 no longer engages the units-rack carrier 13, means must be provided for withdrawing the holding-pawl 12 when thevunits-rack 11 is moved into engagement with the units-wheel, so that the latter may be advanced by the motor .until arrested by a stop-bar 14 engaging the units-rack-to measure the space represented by the stop-ba'r. To accomplish this, a second link 40 is attached to the outer or free end of holdingpawl 12, Figs. 1, 3, 4, and 5, with its lower end properly guided and resting normally upon a lifting-cam 41-, carried by one arm of bell-crank lever 42, the other arm of said lever being jointed to an extension 43 of the rocking frame 6, so that each time a punch is operated lever Z1 2 will be vibrated on. its pivot; Carnal is fornigtl with two substantially arcshaped surfaces of dill'erent radii and con-- nected by an inclined section. Link 40 nor mally rests in contact with the surface of lesser radius, and as the cam advances it raises the link to the higher plane, thereby withdrawing the holding-teeth from the units-wheel and releasing the latter. To secure coordination between the unitsrack and holding-pawl in their action upon the unitswheel, and thus insure the engagement of the one in advance of the withdrawal of the other to prevent the escape of the units\vheel and render the action more certain and positive, the logs or engaging sh0ul ders on the stop-bars and the blade or Wing on the unitsa'ack carrier have been dispensed with and their office of lifting the rack-bar carrier transferred to the cam 41. This is at tained by furnishing the unitsracl carrier with an arm or projection 44, Figs-4 and 5, engaging cam 41' in rear of link 40, so that when said cam is advanced. the incline will ICC ranged to act, through a pick-up, as a driver, for the justification-scale, the latter advanc,

ing intermittingly in unison with the motor 1 rack. The motions thus communicated to Y the scale not only tendedto confuse the oper- Z ,ator, but was a source of frequent damage, 5f 'owingto the'inertia of the parts subjected to ithe sudden starting and stopping of the mozoiitor-rack. To overcome these and other detfects, the motor-rack has been deprived of its function as a driver and utilized as a gage for positioning the justification-scale, the latter remaining stationary until all the erforations 2 5 for a line have been formed an the motorrack brought to a position corresponding with the amount of matter contained in the line, thus forming a gage forsaid line,whereupon the justification-seale or its controlling o device is advanced into contact with the gage "thus formed to position the scale. '1 As illustrated in the present adaptation, I the driving or pick-u mechanism is omitted 'i and the following su )stituted therefor: The 5 motor-rack is provided with a gagingshouli der 46 and a rack 47, the latter loosely supv ported and guided in ways upon said motorrack. The teeth of rack 47' mesh with those of pinion 48 in the train of gears leading to .4othe-justification-scale carrier 16, and said pinion is also engaged by. the teeth of a rack 50, connected to a piston 51, working loosel i in a cylinder 52. A retracting-spring 53 is connected with the train of gearing, and a 5 conduit 54 connects cylinder 52 and port 55 in valve-chest 25, Fig. 7 This port 55 is controlled by the valve 57 of a key 58. Pressure withinlvalve-chest holds valve 57 normally elevated and covering port 55, so that pistorifil rack 47, and the justification.-

I scale remain in retracted positions, to which they are brought by spring 53, the loose fit of the piston lpermitting return motion and serving as ."a cushion. Thus they remain, while the perforations for the line are beingformed and shoulder 46 advanced to final os ition. Upon the completion of the line e 58is depressed, admitting pressure to the cy inder 52 and causing the advance of the '60 justification-scale until its motion is arrested by the contacting of rack 47 with shoulder 46, the latter thus operating as a shiftable gage for positioning the scale. he 58 remains depressed the scale will be he d 'steadily in position; and when released So long as the parts are returned by the spring ready for the completion of another line of perforations.
