Application fiie'd July 14, 1914. Serial No. 850,892.

T 0 all whom it may concern Be it known that I, WILLIAM HUBELI \VALDR N, a citizen. of the United States,

and a resident of Highland Park, in the county of MiddleseX and State of New Jersey, have invented a new and Improved Border-Cutting Machine, of which the following is a full, clear, and exact description.

The invention relates to the manufacture of wall paper, and its object is to provide a new and improved border cutting machine arranged to enable the attendant to keep the design printed on the border in register with the cutting roll, to insure accurate cutting of the border along the'contour of the iniprint. I

In order to accomplish the desired result use is made of an impression roll, a cutting roll operating in conjunction with the said impression roll and having a continuous cutis represented in the accompanying drawings forming a part of this specification, in

which similar characters of reference indi- I rate corresponding parts in all the views.

are journaled the cutting roll B and the impression roll C, between which passes the border D to be out along one edge according to the contour of the imprint on the paper, it being understood that the cutting roll B is provided with a continuous cutting edge conforming in shape to the contour of the said imprint. The border D passes over and under a series of'guide rollers E, E, E E and E journaled on the main frame A, and the border after leaving the guide roller E passes over a roller F prior to passing between the cutting roll B and the impression roll C. The cut border after passing between the rolls B and 0 passes between rolls C andG at the delivery side of the machine and finally passes between guide rolls G, G to a suitable place of discharge.

The guide roller F previously mentioned is mounted on a shaft F driven by gear wheels F F and F from the shaft C of the impression roll C to cause the roller F to rotate in unison with the said impression roll C. On the shaft F adjacent to one end of the roll F is mounted to rotate loosely a sprocket wheel H provided with radially disposed sprockets or pins H adapted to engage apertures D arranged alongside the edge of the border D opposite the one that is cut by the cutting roll B. Each sprocket H is pressed on by a spring H in an out- Ward direction so that the sprockets are free.

to yield radially to readily engage the apertures D of the border D. The hub H of the sprocket wheel H is provided with an arm I of fiber, hard rubber or other suitable insulating material and on this arm is mounted a transversely extending contact pin 1 ful'crumed between spring pressed contact levers J ,\J' fulcrumed on an arm J 2 of fiber, hard rubber or other suitable insulating material, and secured to a hub J 3 fastened on the shaft F so as to rotate with the same. Each of the contact levers J and J is pressed on by a spring J and a set screw J 5 mounted on the arm J 2 serves to adjust the said levers J, J relative to the contact pin I. Normally the contact pin 1 is out of contact with the levers J, J, but whenever the border D is retarded or accelerated then the pin 1 moves into contact with either of the levers J, J to close an electric circuit presently to be described in detail. On the hubs H and J 3 are secured ring H, J of hard rubber or other insulating material and surrounded by commutator rings H J 7 of brass or other material. The rings H, J 7 are engaged by the'free ends of brushes K, K. adjustably secured by set screws K ona pin K held on a bracket K attached to the main frame A, as plainly 15 open position against anadjustable 45 'No; 805,172, granted to me on shown in Fig. 1. The commutator ring H is connected by a wire L with the pin I, and the commutator ring J 7 is connected by wires L with the contact levers J, J. The

5 brushes K, K are provided with binding posts K engaged bycircuit wires Lf, L of which the circuit wire L is connected with a battery L or other suitable source of electrical energy. a The wires L, L connect 10 with electric magnets N mounted on a Y bracket N attached to the main frameA,

and the armature lever N for the said electromagnets N is pressedcon by a spring N I to hold the armature lever normally in an t p N arranged on the bracket N, asshown in Fig.1.

The armature lever N? is. provided with an upwardly extending integral pawl N r-adaptedto engage'a gear wheel 0 forming part of adifferential gearing (ls-mounted on v a bracket A" held .Figsi. "1,2 and 3-). The gear wheel 0 is mounted to rotate loosely on adriven shaft O journaled inthe bracket A, andon the said gear wheel 0 is mountedto rotatea bevel gear wheel V0 in mesh at opposite sides with bevel gear wheels 0*, O", of which the ear wheel 0 is secured: on the shaft 0 e whie the gear wheel 0 is mounted to rotate looselyon the. said shaft 0 Onthe gear wheel 0 is secured a sprocket wheel P connected by a sprocket chain P" with'asprocket wheel P attached tothe hub of a bevel gear wheel 1? secured'on a sleeve C? fastened to the shaft G of the impression roll- 0. The bevel gear wheel P is connected by a return gearing U with the gear wheel Ftin mesh with: the gear wheeLB on 40 the shaft B of the cutting roll B.* This a return gearing, asthe differential gearing 0 before mentioned, is more fully set forth in the LettersPatent of the United States for a registering device for printing machines, November 21, 1905, so that further detail description of the said return gearing is not deemed necessary. ,The-impression'roll O, is provided with a gear wheel Q (see Fig. 2) in mesh with a gear wheel Q mounted on a main driving shaft Q carrying a pulley Q connected with" other machinery for imparting a rotary motion to the driving shaftQ which by the pinion Q and the gear wheel Q rotates the shaft 0 and the impression roll 1 C. The rotary motion given to the shaft C is transmitted by the sprocket wheel Pflsprocket chain P andsprocket ,wheel P to the bevel gear wheel 0? to rotate the latter.

' The shaft 0 is provided with a pulley R connected by a crossed belt R with a pulley R secured on a main shaft pulley S naled in suitable bearings on the main frame A (see Fig. 3). The pulley S is connected on the mainframe A (see is. adapted to'be shifted laterally so as to vary the speed at which the shaft O vis driven from the impression-roll C- and for 1 is engaged by a belt this purpose the belt S shifter S- mounted to slide transversely on asuitable gnideway Sattachdto the main frame A. In the belt shifter S screws a transversely extending screw naled von the guideway S and provided at one end with'a bevel gear wheel T in mesh' with a bevel gear wheel-T secured on a shaft "j ')uri1aled in suitable bearings on a one side of the, main frame A. The shaft T is provided with. a hand wheel T under the control of the operator 'forrturning the shaft T with a view'to rotate the screw rod T to move the belt with aview to shift the belt-S onthe cone pulleys S,- 8?.

The armature lever N may be locke d closed position by a locking arm V '(see- Figs. 1, 2 and 3) secured on a shaft V journaled on the main frame Aand provided with a crank arm V connected by a-link V link V with a 'foot' pedal V under the con-- trol of the operator. The spring V on the link V normally holds the I pedal V in uppermost position so that thevlocking arm V is normally a distance above the armature rod T jourshifter S transverselylever 'N and doesnot interfere with the working thereof. When it vis-desired, however, to lock the armature lever N then the operator on pressing the treadle' VT causes the arm V to'swi-ng downward into engage ment with the armature .lever the pawl N thereof in engagement with the gear wheel 0' rotation. 4 a v The operation is as follows: Normallythe armature lever. N is in open position, that out of engagement with is, with the pawlN the gear wheel 0, the pin I then standing intermediate the contact levers J and'J. The border-D prior to passing between the rolls B and C passes over the roller F, and the apertures D as long'as the sprockets H properlyregister with the apertures Dthe pin I remains intermediate the contact but in case the speed of the border Dis retarded or accelerated then the sprocket wheel H is caused to turn slower or faster to] lock. th e latter against' N to move of the border D engag th v I sprockets H of the sprocket wheel H. Now V levers ,J and J,

me with a'bell crank lever V connected by a a relative to the roll F driven from the imlevers J or J".

pression roll C and consequently the pin 1 makes contact with either of thecontact Whenever this takes place the circuit for the electromagnets N is closed and thearmature lever N is attracted against the tension of the spring N so that the pawl N engages the gear wheel O and holds the same against rotation.-

When this takes place the speed transmitted to the cutting roll B is retarded or accelerated and consequently that of the border D until normal speed is reached, at which time the sprocket wheel Hagain moves the pin '1 into intermediate position relative to the levers J and J. When this takes place the circuit is broken and the electromagnets N are denergized to allow the spring N to return the armature lever N to normal open position, that is, to move the pawl N out of engagement with the gear wheel 0. The latter is now again free to rotate.

From the foregoing it will be seen that i the speed of the cutting roll B is automatiproper registering ofthe cutting edge ofcally retarded or accelerated to insure a the cutting roll B relative to the contour of the design on the-border D, the variation in the speed being very gradual owing to the stopping and releasing of the gear wheel 0 by the pawl N of the'armature lever N.

In case the discrepancy between the cutting edge of the roll B and the contour of the design on the border D becomes too pronounced then the attendant turns the hand wheel T either to the right or to the left to shift the belt S with a view to vary the speed of the shaft 0 thus causing the retardation or acceleration of the cutting roll B according to the direction in which the hand wheel T is turned by the attendant.
