Be it known that LVALBRT I i citizen of the United States, residin at Hamilton, in the county of Butler and r tate of Ohio, have :invented certainnew and useful Improvements in Manifoldmg-Machmes',.

of which :the'follovving is a specicationr My invention relates to anfimprovement in autographic'l registers, andin certaingasf pects to a'mechanical movement for lproducing an intermittent power transm1ss1oncon1 i stant as to direction of its functioning mo# y one stroke to transmit 'motionv thereto, re-

tion and interval of operation imparted o n the powerstroke of an oscillating mecha nism and released therefrom oniits-normalizing stroke.

The disclosure herein illustrated-and de-v scribed is applicable to manifol'ding devices or autographic' registers, comprisingjaI preferred embodiment, for feeding invariable constant lengths of paper uponeach operative stroke of'thef crank handle to reduce the i manual operation for edecting a delivery of a vpredeterminedilength of paper from the machine. The delivered lengthsv are uni-vv formas to ysize Whichare in the nature of preprinted autographic blanks necessitating accurate feed, sopas to insure a full text de livery for each operation and deliver the continuous sheetin registry with af point of severance, so that aflength can be'severed from the sheet along-its divisional line dividing it from the continuous" sheet. The machine isoperated by a crank handle which is oscillated Within' connedlimits engaging a. positive stop at the end of eachv stroke, WhichVrenders it impossible to op-jl erate the paper feeding rolls beyond that re-k quired for a predetermined advanceof paper, eliminating the use of any releas'able stop elements in connection 'with the handle or otherwise :requiring the attention of the operator as now commonly employed in a machine ofthis character operating under a measured stroke. y

With' my improvement no releasable' stop members are required, and* theconfined stroke or reciprocating movement -o'f the crank handle canfbe micrometrically adjust? ed, so that its `povver movement can be regulated With accuracy, relative tothe pre-l scribed'operation required yof the feeding mechanism.` v 'f- An object, therefore, of my inven'tion' yis to provide means movable Within aconned area capable of transmitting motion duringVv`` one of its strokes and neutral in a second, in

'Another object of my invention is to provide an' autographic register with means for supporting a Web or series of Webs lWithin `the registery comprising "a, compartment receptacle for individually 'supporting each {web separate from a second and unitarilv removable from the register.1

The various other features of my inven- 'l tion wlillbe more fully setforth in the descriptioi'i of the accompanying drawings illustratingthe preferred embodiment of my inventicn'gin"a specific use,'that of af manifolding device for autcgraphic registers, but

merely for the purpose of more` clearly and V11o `which alsomaybe regarded in the nature of vfafmechanical movement, and the reference 'herein to a manifoldmg device 1s designated conveniently describingv the various parts, and afuse to aid in a clear understanding of the invention.

Manifolding devices have a variety of uses, with the specific use to which the typek of machine herein disclosed is designed is well known in the art in which a general result isl adapted to be sought, namely to deliver a constant invariable length of paper Within a certain definite movement of a crank handle, and known to the trade as a measured /stroke manifolding machine. To meet the requirements of the users of this type of machine it has heretofore been necessary to make a special machine for each user for thereason ,that no standard length of autographic blank has been adopted. Therefore, great difiiculty has been experienced 1n a type of geared machine utilizing coacting paper-feeding rolls, between which the paper is fed, to construct a machine, 1n which adjustments could be made to render the same vapplicable to various lengths of autographic blanks. In the gear type of machines it has been experienced that delicate machining had to be resorted to in some instances to produce the proper length of feed of certain sized autographic blanks within-a prescribed movement of the crank handle. Further, it has also been customary to provide manually releasable locking means or arresting mechavnism to define the movements @fil-the crank lever or manipulating handle, whieh, under the control of the operator, were aptto be inadvertently actuated, allowing vthe lever to 'be moved beyond its predetermined limit.

It has been found that the use of a pair .of coacting paper-feeding rolls positively rotated by intermeshing gears produce the `most satisfactory result for definitely feeding the strip of paper. Therefore such feed/ ing instrumentalities are employed in my present invention, with the mechanism for rotating them comprised in a reciprocating i for 'oscillating crank handle positively movable in one direction and automatically movable in its normalizing direction, with an. elimination of any releasing mechanism requiring the attention of the operator. The manual performance to deliver a length of paper is materially lessened over the machines known to the art. l

11n the accompanying drawings, Figure 1 is a central vertical section through the apparatus. Fig. 2 is a side elevation thereof with a portion thereofillusti/ated in section.

4 is a detail side elevation of a modified form of web supporting tray. Fig. 5 is a section on line 5 5, Fig. 4.' Fig. 6 is a sidey elevation similar to Fig. 2, illustrating a modified View of paper feeding roll propelling mechanism.

In the drawings, 1 represents the base of the manifolding device 2, 3, the casing side' walls secured to the base, and 4, 5, the end walls hingedly mounted to the side walls 2, 3, for access to the interior of the casing. The upper portion of the casing is provided with the usual form of writing-table 6, and

the margin-frame 7, which may be hingedly mounted'to one of the side frames or otherwise. lAs before stated, the feeding rolls are of well-known construction, comprising a vmounted within slide-ways formed in the side-frames or walls 2, 3.

The-upper roll 9 is provided with a gear 10 intermeshing with the gear 11 of the lower roll 8- for positively rotating said gears. The yupper roll is adapted to be moved away from its frictional engagement with the lower roll to separate said rolls in loading thefmachine, which mechanism for accomplishing such result may be of any Well known form, as illustrated herein comprises a pair of bell crank levers l2, one pivotally mounted upon the axis-of the lower roll at each end thereof, each having an arm adapted to engage with the axis of the upper roll to move the same toward and `from the lower roll. y y

.1.3 represents a rock shaft journaled in the side frames kprovided with pins adapted to engage with said bell crank lever to rock the same, and 14; represents a `handle fixed to the rock shaft, andl as illustrated, connected exterior of the machine.

With the rolls in direct geared connection it follows that'theymust relatively rotate in'opposing directions with their surface tangent traversing in the same direction, tthereby preventing any reverse rota-y tion or slippage of any one ofthe rolls upon the paper between them. The roll 8 being journaled in rigid bearings, constitutes the driving rolls of the series with which the propelling or actuating mechanism is connected during an operating period, Vso that it cannot be displaced or its positive feeding direction interfered with. Upon one end of its axis a gear 15 is fixed, in this instance, exterior of the side wall or frame 2, adapted -to intermesh a toothed contour of the actuating or propelling mechanism and during one stroke thereof. The propelling or actuating mechanism in its .preferred emtnounted -on the crank shaft but oscillates therewith through-the functioning qualifica-'j tion of the crank arm. The guide member,

as illustrated in Figs. 2 and '3, is of hollow a formation, adapted to receive the sector mem-v ber 21, slidable therein, having-its lower edge covering 'the' crank slot 19 'and engaged by thenose' of the'crank arm for moving thel sector'member'21 outwardly radially from the axis .of the crankshaft "17. The sector member 21 has a circular toothed contour serving asa rack to engagev with the teeth v. of the roll gear in one line of its travel and during one oscillating stroke of the crank handle 16 and disengaged from the said gear during a reverse' lineof travel.

The sector member 21 has a slot 22, 'preferably along a diametricalfline, within which a spring 23 is seated, one end ofv the spring j engaged l-with one wall of-'the slot and its opposite end with a cross iece 24 rigidly connected to the guide -mem er 2O 'and projected through the slot 22 for urging the'.

sector 'member toward the axis of the crank shaft tol automatically returnI the sector member to its normal released positionwithin the guide member'. yThus to bringthe propelling contour of the sector member'into a its operative line of travel and traverse coincidentally with the movement of the crank handle it will be seen that the crankarm, in its initial movement, say in a forward di# Lrection, will move idly until it has moved from' the wall 25, of the crank slot 19and engaged with the opposite wall 26, with the nose of the crank arm in its arc of movement from one wall toward the other, forcing the sector member outward radially a suiiicient distance to change the line of travel of the rack or propelling contour to 'bring the pitch line of its teeth tangent with the pitch line of the gear 15. The continued stroke of the crank handle in such forward direction,

maintainingv the parts in their propelling l, position, transmitting motion to the feed rolls. The release of the sector member from the gear 15 is accomplished by substantially a reverse operation from that just described, but its movement is automatic after a release of the crank handle by the f operator through the compressed energy' of a spring fixed to the crank shaft. Thus the contour line of travel of the propelling mechanism is changed cordinately with thel holds the sector member against oscillating movementl or stroke at one of its traversing llmits, while the pawl 30 functions when the sector member is in opposite position. The pawls retain" or lhold the sector -f member against any propelling movement until after..

it has been raised' or lowered, so as not to 'transmit any motion tothe feeding roll,

which might be detrimental to their ypaper jfeeding operation. It will be seen that the pawl 29 will arrest any forward movement of the guide and sector members until after vthe sector-member has been raised or moved radiallyoutwardl and positioned toits intermeshmg lme of travel with the gear 15,

whereupon the'catch 27 will be elevated or Vmoved slightly beyond thehook end of the i pawl and released therefrom. This is accompished during lthe idle movement of the f cran arm in moving fromone wall to the otherof the crank slot in the guide member.

A` s1m1lar operation, but in a reverse vmove-V ment, is obtained by the catch 28 and pawl 30 to release the sector member from its engagement4 with the gear 15 to insurethat 1t has been removed therefrom before the propelling mechanism moves to normal.

Thehshaftl7 is provided with a spring 31, one end thereof fixed to the shaft while the opposlte end of the spring is fixed to ari'gid support,or, as'illustrated, to the side frame,

lfor automatically restoring the crank handle and its oscillating'v members to normal. v

The operator, ina feeding operation, being merely required to move the crank handle 1n one direction, after which the parts will normalize automatically, reducing the man-y ual performance to a mmimum.

To, confine the oscillating movement of the crank handle Within a definite limit, I provide stop lugs 32, 33, rigid with the side frame, each having a screw 34 connected therewith, adapted to engage the guide member 20 atv each end of its oscillating stroke, the screws providing amicrometer adJustment to limit the oscillation or strokes with A'precision relative to the revolution re-` l quired to advance or feed a predetermined measured length of paper. y

In Fig. 6, I have shown a modified form of construction of the guidea'and sector,

members, but which change is merely structural, the operation remaining the same as that described for the form of construction shown in Figs. 2 and 3. In ythis latter instance, theI guide member 20 is provided with the ears 34, .34', one pair upon each end thereof, the ears being oriiced toreceivethe-stems 35, 35, respectively, project-v ing front the sector member 21. Each stem has a spring 36enc1rcl1ng the same,vv one end thcx-'ebf engaged with the stem and the oppositc;'e1nd with one of the cars'foryicldmgly urging the sector member 21 ltoward the axlsof the crank shaft.

It is obvious that various modified forms of construction can be readily devised for accomplishing the result herein disclosed comprehensive within the scope of this invention, and I, therefore, do/not wish to be limited to the specific forms of construction, except wherein specific mention thereof is made in the claims.

In manifolding machines of this type or paper feeding devices, it has been customary to support the webs of paper between journals fixed to the side frame or frames, or components of the side frames, which, in some instances, made it very/inconvenient to insert or remove the webs from their journals, it being inconvenient to gain access to the webs and their supporting mechanism, unless they were eXteriorly accessible, which necessitated an open or skeleton style of side frame or the journals provided with hand holds projecting exterior of the frame.

lnthe disclosure herein, I provide a web supporting tray 37 bodily removable from the interior of the casing of the apparatus,

which tray is provided in compartments 33,

.each receiving a web, as illustrated in Fig. 1, relying upon the weight -of the web or weighted core insert to produce the proper tension required in unwinding the web. In such instance, the tension is differential, decreasing as the web is being unwound, offering advantage in using some grades of paper. Such removable web support or tray, besides offering advantage for properly supporting the webs Within the machine, enables the use of a sealed casing, preventing unauthorized persons from gaining access to the webs.

In the form shown in Figs. 4f and 5, I have provided the removable tray with yielding arms 37', angularly projected from two of the walls of the tray, with each arm provided with a cupped disk engaging into the core of the web of paper. This form of web support is substantially the same as that shown in my prior Patent, No. 925,351, and shown herein merely for the purpose of illustrating a varied range of use of a removable web supporting tray.
