PAPER-REGISTERING MACHINE.

SPECIFICATION forming part of Letters Patent No. 540,352, dated June 4,:1895.

Application filed August 8, 1894.

To a whom it mayconcern:

Be it known that I, TALBOT G. DEXTER, of

Pearl River, in the county of Rockland, in the State of New York, have invented new and useful Improvements in Paper-Registering Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to paper-registering.

devices applied to paper-folding machines or other machines designed to operate on the sons for objecting to running the sheets in a certain way on a printing press to accommodate the printed sheets to the registering and folding mechanism of the machine to which said sheets are subsequently fed, it being un derstood that in registering the sheets on the folding machine said sheets must be presented to the registering mechanism with the same end used in adjusting the sheet preparatory to entering the printing press. It also often happens that the folding machines are used by book-binders receiving the sheets from different printing offices and under these circumstances, it is very difficult to arrange to have the sheets so printed that the margins by which the different pressmen have fed them to the printing press will come to the registering mechanism on the folding machine.

The purpose of my present invention'is to obviate the aforesaid difliculty of registering sheets of paper fed in different positions to the folding machine and presenting their reg istering margins toward different sides of said machine, and to that end the invention consists essentially in the combination with the paper-conveyors and electrically controlled paper-registering mechanism, circuit makers and breakers at opposite sides of the longitudinal path of the paper to be actuated by the adjacent margins of said paper and each removable from its operative position inde- $erial No. 519,751. (No model.)

. pendently of the other to permit either of the two opposite edges or margins of the sheet to be used for breaking the circuit and thereby controllingthe registering mechanism as hereinafter more fully described and specifically set forth in the claims.

In the annexed drawings,Figure l is a plan view of my improved paper-registeringvdevices mounted on a paper-folding machine. Fig. 2 "is a side elevation of the paper-registering devices. Fig.3 is a vertical section on line X X in Fig. 1. Fig. 4 is a vertical transverse section on line Y Y in Fig. 1. Fig. 5 is an enlarged top plan view of the registering mechanism with the armature broken away to illustrate subj'acent parts. Fig. 6 is a vertical transverse section on line Z Z in Fig 5. Fig. 7 is an enlarged side elevation of one of the circuit makersand breakers, and Fig. 8 is a transverse section on line 0 O in Fig. 7.

A denotes the frame of the paper-folding machine.

RR are the rollers which fold the paper tucked between them by the usual folding blade. Not shown.

l5 represents the end-gagewhich arrests the longitudinal movement of the paper fed to the folding machine in the usual and well known manner.

The electrically controlled paper-registering mechanism may be of any suitable construction. For exemplification of. my present invention, I have shown said mechanism of the same general construction as that shown in my prior application for Letters Patent, Serial No. 476,580, filed June 5, 1893,

with the exception of some minor details. 0

Upon the frame -'A- are mounted the horizontal guides g-g which are parallel with the folding rollers -R-R-.-. Upon these guides is mounted the rider ---F- which is adjustable in its position lengthwise of the 5 guides and confined in its desired position by means of a screw -E' which is jour naled in the pedestal --B and works in a nut -N- affixed to the rider F. By

means of said screw, the rider can be moved to adjust the registering mechanism in its position to operate on sheets of different sizes.

In bearings on the under side of said rider is journaled a shaft b which is at right angles to the guides gg and has fastened to it the roller --4"--, which has the top of its periphery nearly or quite even with the plane of the paper fed to the folding machine, and is revolved with its upper portion rearward or toward the adjacent side of the machine. Said roller has its periphery faced with rubber and receives its motion from the driving gears of the folding rollers RR by means of a miter gear -battached to the shaft b and meshing with a similar gear b mounted longitudinally movable on a shaft -Ctwhich is parallelwith the guides g and is provided with a longitudinal groove in which enters a spline in the hubof the pinion. In order to shift said pinion longitudinally on the shaft simultaneously with the longitudinal adj ustment of the rider F- an arm g' is attached to said rider and is bifurcated and loosely embraces the shaft a at opposite ends of the hub of thepinion as more clearly shown in Figs, 1 and 5 0f the drawings. Said arm also serves to supportv the inner end of the shaft a The outer endof the shaft .0t has attached to it a suitable gear awhich derives rotary motion either from the gears of the foldingrollers RR- as shown or from other suitable actuating gears of the. folding machine. Over the roller -r and axially parallel therewith is another roller -r pivoted to the free end of a vertically movable arm C.- which is bifurcated at its opposite end and loosely connected thereat to a rock-shaft-owhich is journaled in-brackets C"--O attached to the rider F. Said rock-shaft receives its motion by means of a miter pinion c attached thereto and meshing with a similar pinion d' on a rock-shaft -d which is parallel with the guides g and has an arm G attached to its outer end. The end of said arm is connected by a rod c to the upper end of alever .I which is pivoted intermediate its length to the frame -A and has pivoted to itslower end a roller by which it bears on the rotary cam -H with which it is held in contact by means of the spring actuated rod e-.

The heel or pivoted end of the arm -O-- has projecting from it a shoulder O upon which bearsa lugc" fastened to the rock-shaft -c, the motion of which shaft causes the arm O to rock and carry the roller r' alternately to and from the lower roller r. Y

On the rider -F are mounted the electro-magnets DD connected to an electric circuit inwhich S denotes the batter'y.

The armature -D- is attached to a lever D which is fulcrumed on the rock-shaft -c and provided with alug directly over the shoulder C"- of the arm O--.-

A short distance back of the roller r is the circuit making and breaking lever pivoted to hangers -10 attached to the rider '-F. Said lever has a rearwardly extending finger l which constitutes one of the terminals of the electric circuit and beneath the finger is the terminal or contact point -l mounted on a bracket -Z depending from the rider F. The finger Z is held normally out of contact with the terminal -Z' by a weighted arm m/ extending from the lower end of the lever -k.

The magnets D are electrically' connected with the terminal Z by a wire e and with the battery -S by a Wire --e" while the other terminal Z is connected with the battery by a wire e-.

The operation of the described registering mechanism and electric devices connected therewith is as follows: During the travel of the paper to the end-gage B, the arm G with the roller -r is lifted by the cam -c'- of the rock-shaft -c pressing down the shoulder G.- of said arm. The lifting of the roller --r'- allows the paper to freely pass underneath it in its travel to the end-gage. The motion of the rock-sh aft c is. $0 timed as to cause the cam c' to release the'shoulder O as soon as the movement of the paper has been arrested by its contact with the end-gage. The arm C is thus allowed to drop and cause the roller r'- to press the paper onto the lower roller rwhich is in constant motion. The frictional contact of the latter roller with the paper causes said paper to be drawn laterally into contact with the circuit making and breaking lever k which is thereby tilted so as to bring the finger Z- in contact with the terminal -Z and thus close the electric circuit. The magnets -D- being thereby energized, causes the armature to be attracted and this causes the lever D- to lift the arm -G sufficiently to relieve the paper from the pressure of the roller r. The lower roller r is thereby deprived of its frictional hold on the paper and the lateral movement thereof is thereby arrested. This completes the operation of registering the paper which registering operation it will be observed depends on the edge of the paper broughtin contact with the circuit maker and breaker. This registering is accurate so long as the sheets are fed to the machine with the sides of the sheets having the uniform margins toward said registering mechanism, but inasmuch as the sheets are liable to be fed to the machine with the uniform margins of the sheet toward the opposite side of the machine as hereinbefore stated, the circuit-maker and breaker adjacent to the registering mechanism cannot always be depended on for controlling the action of said mechanism. For this reason I employ an additional circuit maker and breaker actuated by the margin of the paper farthest from the registering mechanism. This latter circuit maker and breaker may be of any suitable construction having its terminals respectively over and under the passage of the paper so as to become insulated from each other by the paper entering between them and thus break the circuit, and by the withdrawal of said paper from between said terminals during the registering of the paper allow the terminals to come in contact with each other and thereby close the circuit. For this purpose I prefer to employ a circuit maker and breaker constructed and supported adj ustaloly in the following manner: Directly opposite and parallel with the guides, g, g, are horizontal guides ff secured to the frame A. Upon these guides is mounted a bracket .I which has affixed to it a nut N'- through which passes the adjusting screw K- journale'd in the side of the frame A and provided with a hand wheel -K- by which to turn said screw and thus move the bracket longitudinally on the guides -ffso as to adjust the circuit maker and breaker carried on said bracket to operate on paper of different dimensions.

The bracket -J is provided with an arm J- which is under the path of the paper and with another arm -J- which is over the path of the paper. To the free end of the lower arm is fastened the electric terminal n the top of which is in proximity to the plane of the travel of the paper. The free end of the upper arm --J is provided with a vertical guide j' in which slides a pin -n which constitutes the other terminal of the circuit maker and breaker. Above the upper arm J the pin n' has attached to it a collaro underneath which extends the end of alever -o' pivoted to the bracket J-. The opposite end of said lever has a lug -0 projecting from it and over this lug is a lug p attached to the rock-shaft d which extends across the folding machine and intermittently lifts the roller-carrying arm O as hereinbefore described. Said rock-shaft simultaneously lifts the pin n by the bearing of the lug -p upon the lug -0-.

The terminals -nnare electrically connected with the battery S- and magnets -D by wires t-t as shown in Fl 4 of the drawings.

.lVhen the paper is fed to the folding machine with uniform margins of the paper adjacent to the registering mechanism which draws the paper laterally, the terminals n n of the circuit maker and breaker adjacent to the opposite margin of the paper are to be disconnected from the circuit, which may be effected in various ways, either by detaching one or both wires -tt or by placmechanism and thus subject said paper to sufficient tension to flatten or straighten the same in its plane. The upper pin -it' is intermittently lifted by the lug pof the rock-shaft d to allow the paper in process of being fed to pass under said pin.

When the paper is fed to the folding machine with the uniform margins toward the circuit maker nn"-, the latter is to be connected to the circuit and the circuit maker and breaker at the opposite side of the machine is to be disconnected from the circuit. This may also be effected in different ways. In this case the operation of the registering mechanism is controlled by the terminals nnwhich are separated from each other by the interposition of the paper. The circuit being thus broken, allows the registering mechanism to draw the paper laterally from between said terminals which then come in contact with each other and thus close the circuit. The magnets --DDbeing thereby energized causes the armature to lift the arm -C and thereby arrest the lateral movement of the paper. I

What I claim as my invention is 1. An electrically controlled paperregistering machine consisting of mechanism drawing the paper laterally, a plurality of electric circuits electro magnets controlling the action of said mechanism on the paper, and two electric circuit makers and breakers respectively at opposite sides of the path of the paper in process of being fed to the machine, said circuit makers and breakers being controlled by the paper and detachable from their respective circuits to permit only one of them at a time to be operated as set forth.

2. A paper-registering machine comprising mechanism for shifting the sheet laterally, a plurality of electric circuits, electro magnets in said circuits controlling the action of said mechanism on the paper, and two separate circuit-controllers at opposite sides of the longitudinal path of the paper and both adjustable independent of each other laterally in relation to the paper as set forth.

Intestimony whereof I have hereunto signed my name this 25th day of May, 189-1.
