This invention relatesf to improvements in record otyip'conlposing machines, such as the nionotype and for releasing the feeding devices from the actuec'ord strip, with drivingmechanisni therefor ding reirejrsed ratchet wheels on the pin wheel elrrame and. an actuating pawlcarried on an arm pivtecl nponthe pin-wheel shaft, engage one of said ratchet n 'me and acted upon by the -carrying ar n of the actung-pawl, engages the second or reverse ratchet ng and heldirom engagement when the arm is re- Jot-ed and until it again contacts with the pawl during next forward or feeding movement, 1' Thearm'carrpl gthe actuating pawl stands normally the forward extreme ofi-ts mowem'e nt i i-engagement. with theot' erthrow paivl', in which position the three swls'engage their respective ratchet wheels in a man-- 'to prevent 'inovement'of the paper feeding devices either direction j v re turn the paper feeding devices forward is only required that the overthrow pa yl' he released, but when, sisfrequently happens, "it becomes necessary or desilahle to turn the strip feeding devices backward, it is required that the arm'carrying the actuating pawl should not only be retractedto release the overthrow-.

BENTON, a citizen'o'f' United .StatesQresiding ttwsshin ton; District of GoluxhbiaLhave invented certain new and useful Inn and the control unstable, the fingers of the operator be coming, cramped and often slipping, resulting in dams age to the record; strip and necessitating that ithe to'rn or otherwise severed for the-removal oi the dainaged so section and the insertion of a new section. Moreover it is not-uncommon for the 'operators fingers to be caught-and. lacerated. in the performance of this opera 'tion. These diff culties have been overcome by the 7 present invention, and the facility with which it per-1 65 forms'l'th'e whole'operation results in a great saving of time and increases the 'capacityoi the machine; I The improvement comprises mechanical neans for retracting the pawls controlled from a single actuating (lei/ice, such as ale'ver, and operating, when actuated un ons-direction, to Withdraw and hold the pawl s'fifom locking engagement, so that the feeding cieviceswill beiree-to more ineither direction, and, whenectii- 1 ated in the opposite direction, to restore the pawls to operatiye' position, the whole being performed by a' 75 single movement of the hand; to release or restore, thus obviating danger of injury to the operator or paper, -insuring accurate adjustment of all the parts, and-1iherat-' ing'the'hand of the operator so that it may bentilized 1 fol-other purposes, as in effecting the adjustment oi the paper strip relative to the gaging pins oi the feeding mechanisrn. i I I r In the accompanying drawings illustrating apre ierreti form of embodiment of the invention as applied keyboarti Figure 1 is aside elevation of a portion 05' the paper feed tower supporting the strip feeding anti actuating devices'iri operative position, with thedis connecting and restoring device in place. Fig.- 2-.is a "sirnilsr view. with the disconnecting and restoring means shifted or operated to release thestripfeeding devices Fig. 3 is a perspective view oi the pawl con trollcr detached. Fig. l is a sectional View through the lever support showing the retractable holding pin. The same numerals designate like parts in the sereralfigures; v The two ratchet wheels 12; 13, are secured to the pin Wheel shaft upon which latter is pivoted the arm or carrier 10 hearing the actuating pawl 9 engaging wheel 1 12 to-rotate the latter-. The holding pawl 8, piyoted 19M! upon the frame, also engages Wheel 12, to prevent ret-= rograrie movement as pawl 9 is retracted The overthrow of locking'pawl' 14 engages with ratchet wheel 13,

its spring operating oppositely to thoseof the actuating I and holding pawls 9, s and tending mjwiuiamw instead roeor engage its operating endpsaidfpawl being acted upon by-the arm lost the forward extreme or thefeeding, 1nove1nent,to advance its operatingend into-engage 'ment with the Wheel 13; andl thus months-forward j .the Left hand, each pawl requiring a or movement oi wheel shaft, Tne Hill direction to retract pawl 9 and release pawl 14, after which the motion is reversed, pawl 9 engaging and advancing wheel 12 until arrested by the interlocking of pawl 14 with the teeth of wheel 13 brought about by the engagement of said arm.

Suitably supported and guided, as by a'slot and .pin connection 6, 7 with arm 10 and a pivot connection with a-lever 3, is a draw bar or pawl controller 2 provided with shoulders 4, 5, in position to bear upon and lift out of engagement pawls 8 and 9 when said controller is operated. Acting through the pin and'slot connection or the bearing 5 engaging pawl 9, the controller 2 also operates to retract arm 10, thereby releasingpawl l4 and permitting its withdrawal from the holding ratchet wheel 13. Thus by a single movement of the controller all three pawls may be withdrawn from their ratchet wheels, to release the paper feeding devices and permit free motion oithe latter in either direction. When in i'ts normal or retracted position, as shown in Fig. 1, the controller permits arm 10 and pawls 8, 9 and 14 to perform their-usual functions without interference, audit is only when moved to the position seen in Fig: 2, thatit becomes active 'inreleasing said pawls.

To facilitate the manipulation of the controller and retain it in either ahtiv'e or inactive positions it 'is'pivotally connectedto a lever 3 'fulcrumed upon the frame, the arrangement being such that when the lever -is turned to the engaging position, shown in Fig. 2, into contact with a stop 15 on the frame, the point of attachment of the controller will be carried into or slightly beyond a plane passing through the fulcrum' 1. In a deviceof the character described provided with feeding devices and an actuating mechanism including so'3,9s5 v -actuating and overthrow pawls normally engaging their ratchet wheels, and in combination therewith a movable controller for said pawls operating to effect their engagement and disengagement with the feeding devices when in difierent positions of adjustment.

2. In a device of the character described, the coml1ination with feeding devices and an actuating mechanism pawl in position to be acted upon by the feeding pawlactuating device, of a controller engaging the feeding and holding pawls to release the latter and the overthrow pawl.

4. In a device of the character descrlbed, the combination with a feeding pawl audits actuating bar, of a con troller guided upon said bar and acting upon the feeding pawl to withdraw the latter from engaging; position.

In a device of the character described the combination with a feeding pawl mounted upon a pivoted carrier and an overthrow pawl acted" upon by said carrier, of a controller guided upon said carrier and engaging the feeding pawl to retract the latter and the overthrow pawl.

6. Ina device of the character described provided with feeding andoverthrow pawls, and a carrier for the former operating-upon the overthrow pawl to effect its engagement at the limit of the stroke in one direction, and in combination therewith a controller operating to retract the feeding pawl and its carrier. as and for the purpose described.

1. in a device of the character described, the combination with the feeding and overthrow pawls normally en gaging their ratchet wheels, of a controller for throwing,

said pawls to inoperativeposition and means for shifting said con troiler.

8. In a device of the character described, the combination with the feeding pawl carrier -and the controller guided upon said carrier in position to engage the pawl,

= of a lever coupled to said controller and means for retaln ing said lever in different positions of adjustment.

9. In :1 device of the character described, the combination with the feeding pawl and its carrier, of a controller for said pawl guided upon the carrier and connected to an actuating lever, and a stop engaging said lever to arrest- ANDREW J. BENTON.
