NUMBERiNG MACHlNE.

EiPECIPICATION forming part of Letters Patent No. 359,751, dated March 22, 1887.

Serial No. 131,446. (No model.)

To aZZ whom it may concern:

Be it known that I, EDMOND A. 'Wannnu, a citizen of the United States, residing in the city of Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Nu mberin g-Machines, of which the following is a specification, reference being bad to the accompanying drawlngs.

This invention relates to numbering machines containing several numbering -heads which are all carried by one reciprocating cross-head to be operated together for print ing several numbers at a time.

The improvements consist in the novel combinations hereinafter described and claimed, whereby I provide for the convenient adjustment of the mechanism for changing the numbers between the successive printing operations, and whereby the throwing of such mechanism into and out of operation, as required, may be conveniently eiiected.

Figure 1 of the drawings, asafront elevation of a multiple numbcring-machine constructed according to my improvement. Fig. 2 is a vertical section of the same at right angles to Fig. 1. Fig. isa vertical section corresponding with Fig. 2, but showing the numberchanging mechanism in a different position.

Similar letters of reference indicate corresponding parts in the several figures.

A A are two upright side frames or standards, constituting the principal parts of the framing of the machine, and having bolted to them brackets A A which support the table 13 and other parts of the machine, which will be presently described. The lower parts of these standards, which are secured together by cross-ties, are omitted to avoid an inconvenient reduction of the scale of the drawings. These standards contain the uprightguides for a cross-head, G, into which the several numbering-heads D D, arranged side by side, are firmly secured by nuts c a. This cross-head has its ends connected by connecting-rods E E with two cranks, F F, on a rotary shaft, F, which works in hearings in the standards A A, and which is furnished with two spurgears, F, through which it derives motion from pinions G on the main shaft G of the machine, the said cranks and rods giving the cross-head a vertical reciprocating motion. The said cross-head has provided in it a vertical slot for the reception of the numberingheads, as shown in Figs. 2, 3, 4. This slot, which is designated by the letters 12 o in Fi 3, extends continuously through as much of the length of the cross-head as is intended to receive the numbering-heads. Its upper part is only wide enough for the passage of the screw-threaded round shanks caof the stocks of the numbering-heads, which receive the nuts (4 a, but its lower part is wider to receive the square parts a? of the said stocks, which prevent the numbering-heads from turning and which abut against the shoulders if 12* between the wider and narrower parts of the slot. This method of fitting the numbering heads to the cross-head provides for their adjustment at such uniform or varying distances apart as may be desired by simply slackening the nuts a a, the subsequent tightening of which secures the numbering-heads firmly in the position to which they have been adjusted. V

The numbering-heads may, so far as their numbering-wheels and changing devices are considered, be of any known or suitable kind. Those represented are constructed according to Patent No. 140,890. Each has an external change-lever, 2'), furnished with a wristpin, I), for receiving the motion necessary for changing the numbers. This motion is produced by the upward movement of the cross-head, which brings the wrist-pins I) 1) into the forked ends of dogs 0 0, one of which is provided for each wrist-pin, and each of which is secured firmly, but so as to be longitudinally adjustable to a separate'screwclamp, c, which secures it to a horizontal round bar, H, which is supported in fixed hearings in the side frames. This bar occupies a fixed position when the machine is in operation, but it is capable of oscillating or being turned in its bearings far enough to bring the forks of the dogs 0 0 directly over the wrist-pins Z b, as shown in Fig. 2, for operating thereon, or to move them forward out of the reach of and inoperative upon the said wrist-pins, as shown in Fig. 3. The clamps c c afford provision for adjusting the dogs 0 c separately, both backward and forward and lengthwise of the bar, to bring each to a proper provision for the adjustment of the dog higher or lower or toward and from the bar M, to regulate the movement which the actuatinglever of its respective numbering-head will derive from it.

The oscillating or turning movement of the bar H, for the purpose of bringing the dogs 0 to their operative or inoperative position, is effected by a cam-lever, I, arranged on a fixed fulcrum-pin, (Z, secured in the lefthand standard A, the said lever having attached to it a hand-rod, I, the front end of which is within reach of the hand of the attendant standing in front of the machine. The cam f on the upper end of the lever I acts upon a toe or projection, f, on the bar H, to bring forward the dogs to their inoperative position, (shown in Fig. 3) when the hand-rod 1 is pulled forward, but when the said rod is allowed to move back the weight of the dogs brings them to their operative position, which is nearly vertical below the bar H, as shown in Fig. 1.

There is play enough between the cam f and toe f to permit the slight vibration of the dogs necessary for them to accommodate themselves to the arcs described by the levers b. There is a notch, 6, provided in the lower edge of the rod 1 to engage with a stop, 0*, on the table for locking the dogs out of gear, as shown in Fig. 3, and there is a stop-piece, e, on one side of the said rod to engage with the said stop e* to stop the said rod in a position for the cam f to keep the shaft H to a position in which the dogs are operative, as shown in Fig. 1. i

The ink-table represented, and which I propose generally to employ in this machine, is the subject-matter of my Letters Patent No. 330,533, dated November 17, 1885, and there fore needs no description here further than is necessary to explain its application in connection with my invention. The said table consists of two disks arranged side by side, with their faces in the same plane and their peripheries toothed and geared together. Each of the said disks is fitted to turn on one of two pivots formed on the end of two arms, K, which are firmly secured to the back of the cross-head G, and thei r faces are both presented in a backward direction at an inclination of about forty-five degrees. The ink-rollers P P, of which two are shown, have their hearings in opposite ends of two short yokes which are fitted loosely on a central shaft, h, which is.

firmly secured in the lower ends of two levers, J, the fulcrum-pins i of which are carried by the two arms h M of a rock-shaft, M, which is fitted to hearings in standards N N, erected on the cross-head O, and which has firmly secured to it two toothed sectors, M M, which gear with two stationary toothed racks, Q Q, erected upon the top of the standards A A.

the upper ends of the levers J, and so keep the ink-rollers l? P pressedtoward the face of the ink-table or toward the printingsurfaces of the type-wheels, according to the position of the said rollers. The tension or pressure of these springs is adjustable by means of nuts j, fitted to screw-threads on the guide-rods j j, to adjust the pressure of the ink-rollers.

On opposite sides of the ink-table there are rigidly attached to the back of the cross-head C, by brackets 7r and-braces two bent guides, Z Z, portions of which have an inclination parallel with the face of the ink-table, but the lower portions of which are horizontal and situated under the cross-head about level with the printing'surfaces of the numbering-head wheels, as shown in Figs. 1, 2, and 3. Against these guides work the guide-rollers provided on the shafts of the ink-rollers.

As the crosshead moves upward and downward the rock-shaft M receives an oscillating motion through the sections M M and the fixed racks Q Q, and this oscillating motion causes the ink-rollers to pass back and forth under the control of the guides Z Z across the faceof the ink-table and under and in contact with the numbering-wheels to produce the ink-. ing of the latter, the lovers J acting under the control of tliesprings j to keep the guide-rollers on the ink-roller shafts in contact with the guides Z Z.

The rotary motion of the ink-table is do tained through a pawl, it, carried by a lever, n, pivoted on the pivot of the disk L of the said pawl acting 011 a ratchet-wheel, a, secured to the back of the ink-table, andthe said pawllever being actuated by alever, 1;,which works on a fulcrum, p, in a bracket, 19 secured to the back of the cross-head, and which is itself actuated by a wiper-pin, g, carried by an arm, q, secured on the rock-shaft 'M. The return movements of the pawl-levcr and the lever 11 are produced by a spring, a, which connects the pawl-lever n with the crosshead O, and which draws the lever 12 back against a stop in a guide, 8, 011 the back of the cross-head.

R R are rollers carrying the smut-sheet S over the stationary bed T of the machine. As,

however, these rollers and smut-sheet are not 1 .IIO

capable of oscillation, the clamps 0, adjustable backward and forward thereon, and the forked dogs 0, adjustable on said clamps, all suhstantially as and for the purpose herein described.

2. The combination, with the reciprocating cross-head and several attached numberingheads, and the bar H, supported in fixed bearings and carrying a number of dogs corresponding with the numbering-heads for effectro ing the changes thereof, and having a toe or projection, f, of the cam-lever I, its cam f, and rod 1, forbringing the said dogs into and out of their operative position, but leaving them free from the said lever when in their operative position, substantial] y as herein set I 5 forth.
