Application file kl April 5, 1899. are No. 711,774. on model.)

To all whom it may concern:

Be it known that I, FRED LYON, a citizen of the United States, residing at Ithaca, in the county of Tompkins and State of New York, have invented a new-and useful Shifter and Regulator of Paper or other Flat Mateiialin Machines, of which the following is a specification.

Ihe chief, essential, and distinctive feature I of my invention consists in the use of a wheel or wheels arranged for contact with and pres- .through the machine.

sure against the surface of moving paper or other material, as required, the tangent line of cont-actof the wheel being oblique to the normal line of travel of the paper, thus producing by the friction of the periphery ofthe wheel a shifting or change of position of the paper or other material laterally away from said tangent line, much as the water in a running stream is deflected by an obstruction oblique to the line of the current.

In this specification and the drawings herein referred to my invention is especially de-' scribed and illustrated in its application and relation to web-printing'presses, so called, and other machines in which the paper or other flat material is fed to or through the press or machine in the form of a web; and the object of my invention when applied to such a machine is to provide means of correcting and preventing the side motion or displacement of' the web in its travel to and For convenience in this specification I shall uniformly use the word web;- but it is here expressly stated that I donot mean to belimited to that form of material, but include any moving fiat I ,shapes of paper or other material whether propelled by tapes, rollers, or otherwise.

lleretofore in the class of machines mentioned, and especially in web-printing presses arranged to print directly from flat forms, type, or stereotype or otherwise, troublehas been experienced in the tendency of the web to work to. one side or' the other on itsbet coaxing or guide rolls, with the result of breaking the web, printing or folding out of.

place, or some or all of those results. 'It has thus been necessary for an attendant to give inore or less constant attention to keeping the web in proper place at one or more points in its course, so as to secure accurate and unipivot'for' E,

form register of the printing or folding, or both. The same trouble, differing in degree,

is experienced with perfecting and cylindrical presses, so called, and other machines. I obviate these difiiculties and attain the objects hereinabove mentioned with the device and mechanism illustrated in the accompa-' nying drawings, in which- Figure 1 isaperspective view of my in vention applied at a coaxing or guide roll of a machine with mechanism for operation automatically. Fig. 2 is a top view of the principal part of my device. Fig. 3 is a vertical section of the same on the line 1 2 in Fig. 2. Fig. 4 is a vertical section of a circuit-maker and means of application and adjustment. Fig. 5 is a-top view similar to .Fig. 2, but with electromagnet and armature support rela- 7c tivel y transposed. Fig. 6 is a vertical section of a circuit-breaker for use with the changed construction shown in Fig. 5. Fig. 7 is a top View showing modification for using plurality of wheels. Fig. 8 is a top view showing my device duplicated for collecting lateral dis-- placement in both directions. Fig. .9 is a top view showing application of several of my devices at different parts of the same machine.

Similar letters referto similar parts through- 8c I out the several views.

A is a coaxing or guide roll of a printingpress or other machine.

B is a moving web of paper, cloth, or any other material. 8

C is a support for my device, with details of'attaching andadjusting inproximity omitted; but ordinary means of adjustably and rigidly attaching the support 0 to the machine and my invention to the support are 94 used and necessary.

D is an electromaguet.

I E is alever or armature-arranged to operate in connection with the ,electromagnet.

F is an adjustable fulcrum-support and situated intermediate its ends.

G is an arm or extension of E, adjustably attached at H, and I is a wheel journaled to the free end of G and free to revolve.

J is a band or tire of rubber or elastic r or inflated material cemented or otherwise firmly attached to the periphery of the wheel I.

The arm G is jointed to the lever E by means "of a bolt K and set-nut L or other suitable Q device by which the arm, may be adjusted and firmly held in relation to the web 13 and the lever E.

The support F is provided with set-nuts M,

ity of the wheel I to the web is adjustable.

The mechanism and means of support of the lever E at its fulcrum-point may be any of those now in use to insure minimum friction and least lost motion. Set=screws N or other suitable means are also provided in connection with the support F to limit and adjust the lever action of E. A contact-plate or armature O is provided, either integral with the lever E or adjustable thereto.

P is a'spiral spring or equivalent counterweight adjustable in the plane of motion of the lever E. An electric circuit through the electromaguet D is provided by a battery Q located at any convenient place and wires connected in the usual manner. A circuitmaker, Fig. 4, is arranged in the circuit and attached to the press or other machine at some point in proximity to the edge of the web B.

" tact.

In Fig. 4, R is a suitable support with.z1d justable means of attaching thereto the arm S, by which means the circuit-maker may be set in greater or lessproximity to the edge of the web, as may be desired. In the construction shown a lever T is attached to theend of the arm S,'with its fulcrum-point intermediate its ends. This lever is provided at U with a shoe of wood or other suitable nonconducting material, against which 'the web will press at times. At or near the other end of the lever-a rigidly-attached arm V, at right angles therewith, and a coiled spring W are provided, the latter being adjustable in ten-- sion by means of the arm X and sot-screw Y, and adjusted to normally keep the springplate Z, by means of the arm V, out of contact with the spring-plate One end of the plate Z is attachedto the binding-post a, and

one end of the plate 5 is attached to the bind- I contact of, Z with z. The adjustment may be as delicate as desired,so that the least. pressure of .the edge of the web at U will make the conhe' wires maybe extended'to and con nect the battery and magnet in eircuitin the usual man ner,and insulation may be provided in all parts necessary. Any commercial electric currentmay be used instead of a battery and any form of electromagnet which depends upon an electric current. For convenience I illustrate the simplest form.

The lever E in actual construction and application of my device may be in any form or shape and the electromagnet in apy position relatively thereto, and the wheel I may be journaled directly to the leverE without the arm G. Said wheel may also be attached directly or by arm G atany point along the lever E' or relatively to magnet, f ulcrum-poin t, spring, or counterweight; butin any construction and application of my device it is necessary that by means of the fulcrum-support or otherwise the lever E and the wheelI shall be prevented from being deflected from their respective planes of motion.

I now proceed to describe the actual operation of my invention when automatically arranged, as hereinabove described, with this reminder, that its automatic action depends on a normally open circuit, the electromag- 8.0 net D being in consequence normally inactive. I l

The lever E and contact-plate O are so adjusted by the means described that they are normally held away from the electromagnet D when the circuit is open and the wheel I raised from contact with the web B.

The wheel I is so adjusted by the arm G; as shown in Figs. 2 and 3, or by theposition of the leverE that when the periphery of the wheel is brought in contact with the web and pressed upon it the tangent line of contact is more or less oblique tothe sides orline of travel of the web and angled away from the direction in which itisintended to have the wheel operative to slide or shift the paper. VVhen the web becomes out of place, so that its edge crowds against the shoe U, contact of the plate Z with the plate .2 is made, the eleetromagnet is energized, and the lever E and the armature 0 are attracted or pulled toward the electromagnet, and the wheel I accordinglyis brought in contact with the web and presses against it and the roll and by its pressure and friction is instantly operative to push and move the web laterally and continues so to do until the pressure of the edge of the web againstthe lever 'lof the circuit-maker ceases, when the circuit opens, the electromagnct loses its attracting energy, the lever and armature recede from I10 "the magnet, and the wheel I is removed from It will readilybe seen that to automatically, r 20.

correct the side motion of the web in both directions an entire duplication of the mechanism is necessary, the only difference being that the tangent lines of contact of the two wheels must. be oblique to the line of travel of the webin opposite directions to each other. This is shown by'the dotted wheel and arm in .Fig. 2. The circuit-maker for each would of course be attached on the side opposite to that toward which the respective mechanlsm c is to operate to shift the web. The two shlfters may be set-close together in the same support or they may be set one near'each edge of the web or one or both at any pointintermediate.

Fig. shows the arrangement of two-shifters for this purpose on the same machine. It may also he found useful to apply my shifters either singly or in pairs at several different places in the same machine, depending on its construction, use, and the kind and qualtity of the web. This is shown in Fig. 9 of the drawings. I

The wheel I doesnot seem to be as effective in its operation without the rubber or elastic band or tire which is used to increase the friction or grip on the web. By the adj ustment of the lever E the pressure of the wheel and proportionally its friction on the web may be regulated within certain limits. The strength or energy of the electromagnet is also usable as a factor for this purpose. It

is also hereby understood that the width of the or tread of the wheel may be varied to accomplish the objects sought.

In Fig. 7 is illustrated another means of increasing the effectiveness and usefulness as well as shifting power of my invention by mounting two or more wheels I by means of their arms G to' a cross-arm g,.the latter being adjustably. attached to the lever E, it being necessary, of course, that the tangent lines of contact with the surface of the web of the wheels so mounted shall be parallel. Aplurality of wheels may also be journaled directly or by means of arms along the lever E for use for shifting purposes in some forms of machines.

The point of application of my device to any machine for the purpose specified will be.

at any part where necessary for efiiciency and convenience at which the intervening paper or other flat material may be pressed by the wheel against an adjacent unyielding smooth surface already existing or which may be applied. This surface may be either. flat' or curved, stationary or in motion. I therefore do not mean to limit the application of my invention to a coaxing or guide roll as shown 5 in the drawings.

Fig. 5 shows relatively to the wheels the portions of the electromagnet and armature support or fulcrum-point transposed and a weight P used as an equivalent of the spiral spring Fig. 6 is a circuit-breaker for use with the changed positions shown in Fig. 5. It will be seen that in these constructions a closed circuit will be the normal condition and the pressure of the edge of the web against the end or shoe U of the lever T in Fig. 6 serves to break the electric circuit by allowing'the spring-plates Z and z to separate, which normally are held in contact by the spring W, the arm X, and set-screws Y. This adjustmentis accomplished by changing the position of the arm V so as to press against: instead of Z, as in the circuit-maker,

V Fig. 4, hereinahove described.

Upon comparison of the two cousin-notions;

Figs. 2 and 5, it will be seen that in Fig. 5 the pressure of the wheel I on the web and roll will depend on the weight of the wheel and. the spring or balance adjustment of the lever E whenever the circuit is broken and the elec- -trom agnet releases the lever E, which is normally attracted. In Figs. 2 and 3, on the other hand, the pressure of. the wheel will dc pend on the strength and pull of the electromagnet, which quality will depend on its construction or the strength of the electric current, or both.

The construction shown in Figs. 2 and 3 will be more positive and delicate in operation and will admit of a wider range of effi-.

ciency and application, and both constructions relate to the automatic operation of my invention;

I make no separate claim of novelty forthe use and adaptation of an electric circuit, electromagnet, circuit makers and breakers,- &c.,

except in combinationwith my device of a shifter wheel or wheels operated as hereinabove described.

Other means of automatic operation doubtless will be thought of; but it is believed the employment of an electromagnet and an electric current will be found most eificient and economical.

In the mechanisms hereiuabove shown and described the shifter-wheel-I is mounted to press against the material whenever required. I do not limit myself to that manner of operation, but include any means by which the material and wheel are brought in contact and pressure against each other. For example, the wheel I could be fixedly mounted at the requisite angle in proximity to the surface of the material and a roller operated automatically or otherwise to press upon the opposite surface of the material and put the latter in contact and pressure upon the wheel, and thereby make operative the shifting action of the latter. This roller may be similar to or a duplicate of said wheel and arranged to come in contact with and press said material against said wheel directly opposite and in the-same or a parallel line of contact, thus IIO making both wheel and rollersimultaneously operative to shiftthe material laterally.

I am aware that guide-rolls of paper-machines have been mounted on a middle pivoted frame and that in connection therewith adjustable friction-rolls have been used adapted to grip the edge of the web when laterally displaced. I do not claim any such construction. In my invention the wheel is rigidly journaled in proximity to the paper or material, with its plane of revolution intersecting the surface of said material always obliquely to the line of travel of said material and is not normally in contact with the material. Thewhee'l is brought in contactwith and presses upon the surface of the web or other material only when and asdcsired to correct lateral displacement, and is removed from contact and pressure as soon. as the corrcction is made.
