NUMBERING ATTACHMENT FOR PRINTING-MACHINES.

SPECIFICATION-forming part of Letters Patent No. 542,369, dated July 9, 1895. Application filed April 1894 Serial No. 509 ,004- (No model.)

' following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is a side elevation of a cylinder printing-machine having my improved numbering attachment applied thereto. Fig. 2 is an end elevationof the same, looking from v the left-hand side of Fig. 1 toward the right.

Fig. 3 is a longitudinal vertical section on the line 3 3 of Fig. 2, looking in the direction of the arrow 10. Fig. 4 is a similar section on the line 4 4 of Fig. 2, looking in the direction of the arrow 12. Fig. 5 is an enlarged detail of the ratchet-and-pawl mechanism which actuates the numbering-wheels. Fig. 6 is an enlarged detail of the inking apparatus for inking the numbering-wheels.

My invention has for its object to improve the construction of numbering attachments for rotary or cylinder printing-machines; and my invention consists in the construction and combinations hereinafter described and claimed.

In the said drawings, A represents the framework of a cylinder printing-machine.

B is the type or plate cylinder to which the forms or plates are secured in the usual manner, and O is the impression-cylinder.

D represents the mechanism for inking the type-forms on the cylinder B, which mechanism is of the usual construction and will therefore require no further description.

The cylinders B O are mounted on shafts b c, which are connected so as to rotate together with the same surface velocity by gears d e, the shaft bhaving secured to it, outside the frame-work, the driving-pulley E.

To a horizontal shaft Gr, parallel with the shafts b o, and having-its bearings in the framework, are rigidly secured the numbering or type wheels H H, having around their peripheries a series of projections f, as shown in Fig. 5, the faces of which are provided with consecutive numbers up to any desired limitfor instance, fifty or one hundred-to correspond with the numbers desired to be printed on the series of sales-slips or other articles passing through the machine. The number of printing-wheels H on the shaft G will correspond to the number of separate series of sales-slips or other articles extending across the width of the web or sheet of paper I, there being one or more printing-wheels for each series.

The web of paper I to be printed is taken from a roll K, mounted on a horizontal shaft 15, supported in suitable bearings in uprights 16, the paper thence passing under a guide roll 18, over a guide-roll 20, thence up between the numbering-wheels H and the impressioncylinder 0, and between the latter and the type-cylinder B to the take-up roll L, upon which it is wound after being numbered and printed.

I will now describe the manner in which the printing-wheels H are rotated intermittingly. to bring the numbers on their peripheries consecutively into contact with the web or sheet of paper I as it passes up between said wheels H and the impression-cylinder C before receiving the impressions from the forms on the type-cylinder B.

To the shaft G, outside the framework, is secured a ratchet-wheel M, which is actuated by a pawl g pivoted to the outer end of an arm h, which is pivoted loosely upon the shaft G, the pawl being kept inv contact with the teeth of the wheel M by a spring 11. To the arm h is pivoted an arm 10, which is bifurcated at its lower end and embraces a shaft m, to which is secured a cam N, which acts upon a roller n mounted upon a stud projecting from the arm 70, a spring p being secured to the lower end of the arm in and to a pin projecting from the framework, whereby as the cam N is rotated the ratchet-wheel, and with it the shaft G and numbering-wheels H, are rotated a distance equal'to that between two consecutive numbers on said wheels at each complete revolution of said cam, the numbering-wheels being left at the completion of each movement with the projections f out of contact when the wheels H are again moved by the ratchet-and-pawl mechanism just described to bring the next consecutive numbcrs'into contact with the paper and press the same against the surface of the cylinder 0 to produce the impressions as required; The camshaft m is provided with a pinion q, Fig. 4,

which is connected by a train of intermediate gears 1' s with a gear to on the shaft 0, whereby as the latter is rotated motion is communi cated to the cam-shaft m, and: thence to the cam and the ratchet-and-pawl mechanism above described.

By changing the size of the pinion g on the cam-shaft m the number ofrevolutionsof the latter may be made to correspond to the number of forms extending-ina single-line or series around the circumference of thetype-cylinder B, thus rendering the machine adjusts able to suit the requirements of the case, a number being printed at each complete revo lution of the cam N.

The above-described mechanism for intermittingly rotating the numbering-wheels-H is so constructed and timed that it will positively move said numbering-wheels with the same surface velocity asthat of the impression-cylinder C during the time thatithe types on said wheels H are in contact with the pa per, thereby effectually preventing any blurring or rubbing of the impressions and insuring the production of perfect work.

To prevent the numbering-wheelsfrom being carried by their own mometntum farther than is dueto themotion of the actuatingpa'wl g, I employ a friction device consisting of a brake P, which is kept constantly set up:

in contact with the peripheryof a bearerwheel Q, secured to the shaft G of the numbering-wheels. This brake P' is mounted upon an eccentric stud y,.projecting, from a horizontal arm R, extending out from the framework, saidstud having a square end 21,

as shown in Fig. 4, by which it may be turned 3 to keep the brake firmly upto the wheel Q,

with the desired amount of pressure as-the surfaces in contact become worn away. a is a set-screw by which the stud y is clamped in position after the brakehas been set up with the required amount of pressure.

I will now describe the inking apparatus or mechanism by means of which the numbering-wheels H are supplied with ink.

The twonumbering-wheels H are bothinked by a single form-roller S, the shaft of which is supported at its opposite ends in boxes 25, fitted to slide in slots 26 at the lower endsof two arms 'l T, loosely mounted on the numbering-wheel shaft G andconnected together by a tie-rod V, the whole forming a vibrating supporting-frame for the form-roller, to the shaft of which is secured, at its opposite ends, two small friction-wheels b b, which are adapted, when the form-roller is in contact with the numberingwheels, to hear one against the periphery of the bearer-wheel Q, and theother againstthe periphery of a similar bearer-wheel W, also secured to the numbering-wheel shaft G, whereby as the numbering-wheels H are moved the form-roller will be rotated in contact therewith and with the-same surface velocity to ink the same, as

required.

X is the metal inkdistributing cylinder by which the form'roller is supplied with ink and by which the latter is rotated by frictional contact whennot in contact with the numbering --wheels. This cylinder X is monntedon a shat'tc, having its'bearings in the-framework and carrying at one end a grooved pulleyid, Fig;2, which is driven by a cross-belt' c from a grooved pulley f on lthes-haft o of theimpression-cylinder O, the

jcylinder X taking ink-from the roller 35, with which it is always in contact, and being also jvibrated in the usual manner by means of a cam-wheel g, Fl". 2, Quits-shaft co-operating with a roller h-', mounted on a stationary stud projecting from the framework.

It will beobvious that if the form-roller S kderived its motion whollyor at all-times from ithe cylinder X it would, on account of the speed of the latter, have a surface velocity j greatly exceeding that of the numberingiwheels H, and hencethe typesthereon would it'ear and injure the form-roller, and the latter iwould also only imperfectly ink the types. tIt is-therefore desirable to givethe form-roller {the same surface velocity as the numberingwheels when inking thesame. Thislaccomplishby moving the form-roller away from the cylinder Xi and simultaneously bringing ;it into contact with the numbering-wheels, and at the same time bringing the frictionwheels I) into contact with the bearer-wheels ;Q W, which are of the proper diameter, and arranged to revolve the form-roller with the same surface velocity as the numberingwheels-while incontact therewith.

Thearms T are rocked to move the formroller toward andaway from the cylinder X by a lever A, connected-with one of the arms 'T by a link 30, Fig. 6, said lever A being fulcrumed on a stud projecting from the framework, and carryingat its upper end a cam- "roller 32, which is acted uponby a cam B'on the shaft 0 of the impression-cylinder U, which cam moves the lever A againstthe resistance of a spring 11, which encircles a rod pivshaft is acam orincline q',(showu in Fig. 6,) formed at the end of a stationary arm r, secured to the framework, each box 25 being kept in contact with its cam g by a spiral spring 8, placed beneath it in a recess 26, and, consequently, as the arms T are rocked outward by the action of the spring 2" and cam B to disconnect the form-roller S from the inking-cylinder X, the boxes 25 will follow the inclined surfaces of the cams q, thus allowing the springs s to force the form-roller S upward into contact with the numbering-' wheels H to ink the same, the friction-wheels 5 being at the same time brought into contact with the bearer-wheels Q W, which then instantly cause the form-roller to rotate with the same surface speed as the numberingwheels, the arms T, as they continue to move outward, causing the form-roller to ink one or more ofthe types on each numbering-wheel Whether said wheel is in motion or at rest. The arms T are then swung downward by the cam B to bring the form-roller again into contact'with the ink-cylinder X, which causes the boxes to follow the inclined cams g against the resistance of the springs 8', thus withdrawing the form-roller S out of contact with the numbering-wheels H, as required, leaving it free to be rotated at a much faster rate of speed by frictional contact with the inkcylinder X. The cam B, here shown,is constructed to operate the form-roller arms T three times during a single revolution of the impression-cylinder C, but it may be made to operate said arms only once or as many times as may be desired during said revolution of the impression-cylinder C.

t" t are rods provided at their upper ends with heads 36 and encircled by the springs s, which take a bearing on said heads and I against the lower ends of the recesess 26 in the armsT. These rods are provided at their lower ends with finger-eyes u, by which said springs may be pulled down and held when it is desired to remove the form-roller from its supporting-frame or replace it therein.
