Application led lay 11,

This invention relates autographic reg'-` isters and in some of its' aspects more par' a or cut-out portions of the webs.

' In a. more specific aspect, this invention' comprises one or more controlling devices adapted during the feeding operation to rest against imperforate portions of the webs and` for causing'the pin-wheels to be disconnected from the operating means therefor when said devices engage through said perforations in the webs so as to cause the feeding to cease irrespective of further operation\of the operating device.

In some forms of the invention the con trolling devices bytheir movement into the perforations cause the pin-wheels to be dis'- connected from the driving means, while in other forms they positionauxiliary means which upon 'further operation of the pinwheels cause the disconnection to vbe effected.

In some embodiments of the invention the controlling devices merely trip another device so that a spring previously energized will function to cause the disconnection.

s Also in some embodiments of the inven- `tion the controlling devices are permitted to remain in the perforations after the pinwheels are disconnected, but in at least one embodiment the controlling devices are caused to be withdrawn from the'perfora-- tions as an incident to the disconnection of the pin-wheels from their driving means.

Preferably, ing the pin-wheels against moving out of proper relation to each other when discon nected from the driving means therefor. Other features a inafter'appear.

In. the accompan ing drawings: l' Figure l-is a si t1 onal form of autographic register of the pm-wheel type having part of the casing at the delivery side removed and showing my invention as applied thereto, and is taken substantially on the line 1`1 of Fig. 2.

lingers have passedl througlh the apertures and just before the pineels are disconnected'from their driving shaft.

Figure 5 shows the arrangement of the controlling apertures with relation to the web and its Amarginal perforations.

. Figure -6 is a top -plan ,viewyof the' pin i 'wheel and its locking mechanism.

As shown in the accompanying drawings, the autographic register comprises side plates 20 between which is supported a writing bed or platen 21 for receivingfree ends of paper webs supplied from rolls journaled in the side plates 20, suitable duplicating material being provided at the platen for` making manifold copies of -work done manually upon the uppermost web. The

webs are usually printed' so as to provide a succession of forms or tickets which are separated by a tearing operation after a written form has been deliveredl from the machine; The register,`-being of the pinwheel type, also comprises -a palr of pin Wheels 23 at or near the delivery side there-l of which 4have pins 24 projecting through vslots in the platen 21 and f thence through longitudinally arranged series of marginal 'perforations formed in the webs. The pins 24 remaining continuously in engagement y with the Webs, prevent any appreciable relameans are provided for hold-.-

EGRY REGISTER colapresent invention as shown in tive movement between separate superposed lwebs, thus preserving correct reglstration and maintaining the webs properly` aligned platen and other parts 'l or by a prearranged ratio of gearing between the crank and the pin-wheels, when 1t 1s desirable for the crank to have a uniform throw irrespective of the form-length. In such cases it was necessary to especially prepare each register in accordance with the particular form-lengths of the work sheets which in practice requires a large number of eXtra parts and labor. Moreover, the work had to be fitted to the register, to some eX- tent, because these arrangements did not adapt themselves to fine variations or adjustments.

Now, in a register made in accordance with this invention, the extent of rotation of the crank does not determine the length of the webs fed at; each operation; This is controlled by the webs themselvesthrough the medium of apertures arranged therein at predetermined and substantially uniform distances longitudinally of the marginally perforated web, the distances being each equal to a form-length. Mechanically, it is merely necessary that a single series of apertures be provided, but, since it is common practice to provide each ticket with a pair of apertures for receiving the posts of a loose-leaf binder, the webs preferably are provided with two ytransversely aligned series of apertures 25, as shown in Fig. 5.

For cooperating with the apertures 25 there is provided by this invention a pair of feeler fingers 26 mounted on a transversely' arranged bar 27 carried by arms 28 which in turn are secured to a shaft 29 located in rear of the pin-wheels. The ,bail thus is normally urged downwardly by a spring 30 so that the fingers 26 press against theimperforate portions of the webs between the apertures 25 when the feeding operation is in progress, or move into the apertures 25 when the feeding operation has ceased. The movement of the fingers 26 through the apertures 25 is utilized for causing .the disconnection of the pin-wheels 23 from its driving means.

The mechanism for accomplishing the disconnection of the pin-wheels from the driving means will now be described.

The pin-wheels 23 are mounted upon 'and secured to a sleeve 31 rotatably mounted on a shaft 32 journaled in the side plates 20 instead of being directly secured to the shaft as is customary. The shaft 32 constitutes the driver of the pin-Wheels and is prefer` ably provided on one end which protrudes from the register with a crank or handle 33.

The drive shaft 32 is coupled to the pinwheel during the feeding operations and the means for accomplishing this comprises a clutching disk 34 slidably mounted on the shaft 32 and caused to rotate therewith. by means of a spline 35. The clutching disk 34 is preferably provided with similar teeth cooperating with teeth provided on a disk 36 secured to one of the pin-wheels 23 and located at the left side of the register. The clutching disk 34 i's normally urged toward disengaged position in which the pin-wheels are free of the shaft 32 and crank 33.by means of a spring 36.

During feedingl operations, that is when the crank is driving the pin-wheels, the disk I34 is held in clutching position (see Fig. 4)

by an arm 37 pivoted on the shaft 29 of the controlling finger bail, the forward end of the ar1n'37 having a roller- 38 for directly engaging the disk 34.

In the form of the invention being described, the arm 37 normally tends to move upwardly, yas hereinafter set forth, so as to free the\clutcliing disk 34, but is prevented from doing so by a latch 39 pivotally mounted on the arm 37 .and provided at the`end of one of its arms with a hook 40 which engages with an inwardlyprojecting pin 41 mounted on one of the side plates 20. The latch 39 has another arm provided with a pin 41b whose purpose is to project into the downward path of travel of the bail arm 28 of the controlling fingers, whereby the latch is moved against the tensioni of its spring 42 when the arm 28 moves downwardly as an incident to the movement to the fingers through the apertures in the webs. The position ofthe parts at this time is shown in Fig. 4. A further movement of the arm 28 y causes the latch 39 to be fully released and the arm 37 moves upwardly to release the clutching disk 34 at which the feeding of the webs ceases.

Since the webs are always held by the pins 24 and have no opportunity to become disaligned, there is no need of the fingers 26 remaining in the apertures 25, the fingers are automatically withdrawn from the apertures simultaneously with the movement of the clutching disk 34 to that of pin-wheel releasing position. This is accomplished by llimiting the rearward movement of the latch 39 by a stop 43 so that the finger bail 27 is raised by the upward movement of the arm 37 through the, engagement of the arm 28 by a pin 41b of the latch 39. 4

To prevent accidental movement of the pin-wheels during the time in which the lat- .terare disconnected from the shaft 32, the

clutch controlling arm 37 has secured thereto a locking arm 44 having a bent end 45 adapted to engage between two of the pins 24 of one ofthe pin-wheels as shown iii Fig. 1. A spring 44a tends to hold the locking arm 44 in pin-wheel engaging position and the arm 37 is thus normally urged in its upper position by reason. of the arms 44 'and 37 being secured together. After the clutching disk has been released, the arm 37 in its upper position rests upon the disk and is revented from returning so long as the disk is in unclutched position.

'The/forms which have been fed or delivel-ed from the register by the feeding op-, eration are then torn or severed from the webs by' a knife 46 placed in advance of the pin-wheels.

For engaging the clutching disk 31 with the cooperating disk 36 on the pin-wheel 23 when it is desired to deliver the next form from the register, there is provided a cam -tT carried by an arm 4S pivoted at 49 and having a handle 50. When the handle 50 is moved to the position shown in dotted lines in Figure l. the cam 47 engages the disk it and shifts the saine. to clutching position with the member 36 against the tension of the spi-ing 3G. At the Sametime a `vielding `member l, preferably a rather stitf llat spring. carried b v an arm 52 secured to the cam arm 1S is moved into engagement with the bent end l5 ofthe pin-wheel locking arm l and tends to move said arm 41 out of locking position and to return the clutch controlling arm 37 secured thereto into position to hold the clutching disk in clutching position and these movements are effected as soon as the clutching disk is in clutching position. When the arm 37 moves downwardly,v its latch 39 is movedvby its spring-into engagement with the pin ll so that the arm 37 is locked down. The coni rolling fingers :26 and their arms 28 are held up during the recoupling of the pin-wheels to the shaft by an arm on the Cani arm shaft t9 which engages" one of the arms 28 at the beginning of the movement of the cam 47 and remains in such engagement during the entire movement of the cam. lVhile the g handle 50 is held in operative position shown in dotted lines in F ig. l, the crank 33 is rotated to start the feed of thel webs. After the apertures have passed out of range of the controlling fingers 26, the operator releases` the handle and rotates the crank until it is observed that the feeding ofthe webs has ceased and a form has been delivered.

The pin-wheel sleeve 31 is heldin proper position on the shaft 32 against axial movement b v means of an arm c'mounted on the underside of the platen and engaging an annular groove formed by flanges 56 se cured to the sleeve 31.

In the form of the invention' just described, the power for disconnecting the pin-wheels from their shaft is supplied by the manual operation of the starting handle 50 and is stored in the spring 36 for the clutch controlling arm 37.

Variations may be resorted to within the scope of my invention and portions of the improvements may be used without others.

The mechanism per se shown in Figs. 5 to 10 is reserved for protection by means of divisional applications carved out of the present application. such divisional applications bearing Serial Nos. 691,787 and 691,758 and filing date February 9,1921.

I claim as my invention:

In an autographic register, the combination of a. platen over which webs are fed; pin-wheels for feeding said webs; a driver for said pin-wheels; `a clutch for connecting said driver to said pinlwheels, a spring tending to move one member of the clutch out of connection with the pin-wheels; an arm for holding said clutch in clutching position; a spring normally tending to move said arm to ineffective position; a latch for holdingsaid arm in effective position; and a feeler device adapted to enter apertures as arranged at intervals along said web for causing the release ofl said latch when the `feelers enter said apertures.

In testimony whereof, I allix nity-signature'. I
