Specification of Letters Patent.

Patented Feb, 8, 1916.

Original application filed August 5, 1911, Serial No. 642,544. Divided and this application filed il'am'mryv 21, 1915, Serial No. 3,591. Renewed November 1, 1915. Serial No. 59,148.

To all whom it may concern:

Be it known that we, GLENN S. WILLIAM- SON and CHARLES E. MANDELICK, citizens of the United States, and residents, respectively, of New York, borough of Manhattan, county and State of New York, and Ridgefield Park, county of Bergen, State of New Jersey, have invented certain new and useful Improvements in Margin-Regulating Mechanism for Web-Rolls, of which the following is a specification.

This invention relates to web guiding mechanism and to margin-regulating mechanism for web rolls, and the subject-matter hereof constitutes a division of our application filed August 5th, 1911, Serial No. 642,544, now Patent No. 1,160,556, Which application is directed more particularly to means for maintaining a uniform tension on the web, the same including a braking electric generator driven by the Web.

The object of this invention is to produce a simple and effective mechanism whereby accurate axial adjustment of the web roll mav be effected to keep the web running true and thereby preserve uniform margins.

A further object is to combine such mechanism with the connections for driving the generator, so as to produce a unitary apparatus that can be connected with and disconnected from one end of the web roll' spindle, thus making possible a compact and advantageous arrangement and permitting ready replacement of the web roll and spindle.

A further object of the invention is to provide a simple and efficient mechanism whereby accurate adjustments of the web roll may be effected in .printing presses so -as to preserve uniform margins and to regulate the margins of the web with relation to a printing couple of the press.

To these ends the invention comprises the parts, improvements and combinations herein described and illustrated in their preferred forms and more particularly .pointed out in the appended cla1ms.

In the accompanying drawings showing the preferred embodiment of the invention: Figure l is a plan view, partly broken away and partly'in section, showing the applica-. tion of the invention to a printing-press, the cover being removed from the braking tion on an enlarged scale, the plane of the section intersectin the axis of the'web roll;

tail in the aforesaid application and need not here be set forth with the same detail.- It comprises an electric generator 11,the armature of which is drlven by the roll spindle 8 and the fieldof which is floating or rotatable so as to be turned by the torque of the armature. The field frame 12, as it turns, by means of a gear ring 13 which it carries, operates a suitable rheostat not The; brake mechanism" shown is illustratedand described in deshown) to cut resistanceprogressively into 1 I the armature circuit, so that the braking effect. of the generator is diminished as the roll decreases'in size and its angular" velocity increases. Since the' progressive introdu'ction of resistance into the armature circuit diminishes the drag of the. armature on the field, means are provided for opposing decreasing resistance to the turning of the field by the armature, an embodiment of which means comprises a suitable cam 14 turned by the field frame through gears 15, 16, and acting on a flexible connection 17 to raise a lever 18 carrying a weight 19.

All of this is fully set forth in our prior application, to which reference may be had for details. p

The armature of the generator is driven from the spindle 8 by a. clutch 20, a telescopic shaft 21, a gear 22 on the end of said shaft, and a pinion 23 on the armature shaft and meshing with said gear. The clutch is preferably a magnetic clutch, and comprises a conical electromagnetic member 24: at the other end of thetshaft and a concave conical armature member 25 fixed to the end of theroll spindle. The coils 26 of the clutch are supplied with current from any 21 includes two telescopic sections 28, 29,

which turn in suitable bearings 80, 31. The section 28 carries the gear 22 and does not move axially. The section '29 constitutes an external sleeve which is slidable on the section 28 but is suitably connected there with so-that the two rotate together. The sleeve 29 is preferably connected withthe clutch member2t; by universal joints which compensate for any lack of exact axial alinement between the shaft sections 28, 29 and the spindle 8. To thisendthere is an angularly movable shaft section 32' which is connected with-a flange 33 fixed-'tothe sleeve 29 and to a plateBt fixed toflthe clutch member 24:, by means of universal joints 35, 36. Casing sections. 37, 38 'arelilrew'i'se fixed to the said fiangeand-plate and have their opposed ends spherica concaved ends of casing sections 39, 40, the opposed ends. of which are cylindrical and receivedione within the other; and a spring 41 is confined between these last two sections and tends to hold this flexiblepart at the screw to move in a straight line.

"Means are provided for shifting the roll spindle T8 axially either electrieallyor :31 hand. The electrical means include a sm l electric motor 42, which is also carried by the support tend is of a character suitable for running in either direction. llt operates through. the connections for driving the generator 11 and for connecting and disconmeeting the same with thev spindle. To this end its shaft carries a worm 43, which meshes with a worm wheel 44, which in turn is mounted on the upper end of a vertical shaft 45 mounted in a bearing 46 on the support. The shaft 45 carries at its lower end a bevel gear 47, which meshes with a bevel gear 48 on a screw shaft 49. The latter is disposed parallel to the shaft 2i and is journaled in suitable bearings 50, till mounted on the supporti). llts threads en- 'age with a nut 52 pivoted to the end of a lever 53, which is fulcrumed at 54 on the support, the lever being slotted at this end because its free end is constrained by the latermediate its ends the said lever engages a and received by the collar 55 on the slidable shaft section 29. Obviously any suitable'shifting device may be employed in place of the lever 53.

Fig. .5 illustrates a form of wiring for startingand stopping the motor and cans ing it to run in either direction. Wires 56, 5? connect with the field coils, and wires 58, 59 with the armature brushes. When the switches R and L are in the positions shown, no current passes through the motor, which remains at rest. When the switch L is moved against the contact 60, current passes from the plus line wire by wire 61 through the field coils, from wire 57, to wire 62, thence by wire'59 to and through the armature in one direction, and by way out the wire 58, switch lit and wire 63 to the minus main. With the switch L in the position shown and switch It in contact with lid,

the current passes as before through the 1 field coils, but is reversed through the armature, so that the motor runs in the reverse direction. Suitable means are provided for operating switcheslt and L. In the particular embodiment of the invention illustrated the switches R and L are operated manually. It will thusv be seen that the motor may be operated to shift the web roll axially in either direction through a suitable reducing gearing acting upon certain of the connections for driving the braking generator.

The manual means for adjusting the web roll spindle is shown as comprising horizontal shaft 65 journaled in a bearing on the support-9, a hand wheel 67 on the outer end of this shaft, 'anda bevel gear 68 its inner end meshing with the bevel gear on thescrew shaft49.

Means are provided for permitting slip to occur in the connections between the motor 42 and the spindle 8, so that by accident the spindle were shifted as far as it could go in either direction with the motor still running, no damage would result to the latter because the slip connection would yield. lBy locating this slip connection between the motor and the manual adjustinr means, it also permits the spindle to be ad justed manually without turning the armature and without encountering the d'tiiculty or impossibility of turning the r' from the worm wheel at. Prefer slip connection is between the said wheel and the shaft 45, As shown, worm wheel is mounted loosely on the l end of the said shaft, but is normally tionally coupled therewith by means a s ring 69 which presses the worm wheel ownward against a friction member or collar 70 on the shaft.
