Application filed January 10, 1923.

T 0 aZZ 107mm 711- may concern:

Be it known that I, CHARLus A. MEISEL, a citizen of the United States, and a resident of Boston, county of Suffolk, and State of Massachusetts, have invented an Improvement in Apparatus for Printing Numbered Impressions, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to printing devices and more particularly to devices which are adapted to print a series of numbers on successive impressions and the object more particularly is to provide an arrangement of this character which will provide for one or more supernumerary impressions between successive series of numbers without danger of confusion.

My invention will best be understood by reference to the following description of an illustrative embodiment thereof taken in connection with the accompai'iying drawings, wherein:

Fig. 1 is a diagrammatic side elevation of portions of a printing press partly broken away to show the portion at the upper left hand part of the figure substantially on the line 1-1 of Fig. 2;

Fig. 2 is a longitudinal section through the numbering head shaft Fig. 2 is a detail;

Fig. 3 is a section on the line 33 of Fig. 2;

Fig. 4: is aside elevation of a cam;

Figs. 5 and 6 are sections on the lines 55 and 6-6 of Fig. 2 respectively; and

Fig. 7 is a section on the line 7-7 of Fig. 3.

Printing mechanisms for printing a series of consecutive numbers, as, for example, on a series of tickets or coupons, are well known as are also means for causing an intermission of the numbering operation between the printing of successive series. By way of example I will refer to the patent to Charles A. and Francis Meisel, 1,186,020,

June 16, 1916, and the patent to Francis Meisel, 1,03%,637, August 6, 1912. In view of the art as disclosed particularly by these patents, the illustration and description of certain mechanisms herein will be consider- Serial No. 611,901.

ably abbreviated. By way of example we may consider the printing on a continuous web of sets of coupons, the elements of each set oi which are to be consecutively numberethsay from 1 to 100. That is, the first one hundred coupons will be numbered serially and then thcnumbering mechanism will be manipulated to cause the series to repeat. To facilitate the separation of the coupons belonging to individual series for collection and assembly it is desirable to have a certain space between successive series and this may be efiected, as in the patents referred to. by stopping the operation of the numbering mechanisms so that the last number of the series will be repeated a certain number of times. As a result of this operation there are a number of waste or extra coupons in the series and to avoid confusion and also because what have herein been referred to as coupons may be certificates of value, I provide in accordance with my present invention means for printing on these duplicate elements with an auxiliary printing device which may indicate that they are not true and valid elements of the series but merely waste. In the example of my invention here chosen for purposes of illustration the word Void is printed on the coupons of duplicate number.

Referring particularly to Figs. 1 and 2, I herein show certain elements of a numbering printing attachment bearing considerable resemblance to that shown in the patent to Francis Meisel 1,034,637 above referred to. Opposing a suitable impression cylinder 9 there may be arranged a shaft 11 carrying a suitable number of numbering heads 13 of well known type. To cause the operation of these numbering heads so that they will print successive numbers each head or set of heads may be controlled by a cam arrangement embodying the relatively stationary member 14 and the slidable member 15 which are provided with the grooves 17 and19 in the form of circular arcs. When the elements are spaced from each other as in Fig. 1 the grooves 17 and 19 form an eccentric track adapted to actuate the pawl lever of the numbering head as described in the patents above referred to but if the member 15 is caused to approach the member let the two grooves will form a circular track which will be without effect on the numbering head. The member 15 may be provided with a rack 21 which meshes with a toothed shaft extending across the press from one frame to another, the rack herein engaging with the underside of this shaft. If the shaft 23 is given a partial rotation clockwise from Fig. l the 'am section 15 will be moved to the left and the operation of the numbering head will be stopped and until the reverse action takes place the same number will be printed repeatedl Herein theshaft 28proj acts at the side of the machineand provides at the outer end a pinion with which meshes a sector gear lever which may be rocked by the lever arm 2? having a nose or follower 29 cooperating with a cam 31 toward which the lever is pressed by a spring The cam 81 is pr.- vided with a depression 35 into which the nose 29 may drop and when this occurs the arm 2T will swing counterclockwise as will the sector 25 and the pinion shaft 23 will be rotated. The cam 31 is rotated by a ratchet wheel 'l'operated by a pawl 39 on the pawl-carrying lever ll which is intermittentlyoscillated by connecting rod from a crank on the impression cylinder 9. On each rotation of the impression cylinder 9 and in definite relation to the number of impressions the ratchet wheel and consequently the can'i 31 is incrementally advanced and thus after a certain number of impressions has been made and the desired numerical series is completed the notch in the-cam will come opposite the follower or nose 29 and the mechanism will be operated'to shift the cam part 15 and stop the operation of the'nnmbering head which will thenprint the same number repeatedly for a certain number of impressions until the follower or nose29 rides out of the recess 1 35 after which the series will be repeated.

Inthe drawing I have also illustrated a manual adjusting means substantially as shown in the patent to Francis Meisel, No. 1,034..637, above'referred to.

in accordance with my invention I pro vide a suitable printing mechanism governed. in opposite phase to the numbering head or heads to 'print suitably on the work when the i'unnbering head is no longer operating and is printing duplicate numbers. .e'terring particularly to Figs. 2 and 6 in the present embodimentof my invention I have shown a cylinder or wheel mounted on the numbering head shaft 11 and opposing the impression cylinder 9 and mounted radially in this wheel 45 are provided type-carrying plungers 47 which may carry suitable printing types 49 on their-faces and herein I have shownsuch a type bearing the legend Void as shown in Fig; 2. In the embodiment of the invention shown four impressions are made or four coupons or the like printed on each revolution of the printing couple and l tl'lGl'QfOlG show here four type-carrying plnngers. These plungers 47 are provided with stems 5i having heads on which act helical sprin s normally tending to draw the plunger-s radially inwardly to a position in which they will not print as they pass the impression cylinder and means are provided whereby the plungers may be forced radially outwardly at proper times to permit them to art. in the present in stance this ma y be effected by means of cams acting on the heads 55 of the plungers and which may take the form of rods or shafts housed in suitable grooves in the numbering head shaft 11 and having flattened sides 9 as best shown in Fig. 6. It will. be understood from that figure that if the flattened s s of these rods are presented to the heads the springs will draw the plungers inwardly and the types will be in inoperative position but if the rods are turned as shown at the left of Fig. tithe plungers will be forced. outwardly and the types will be in operative position.

This operation of the plungers is effected in opposite phase with the control of the numbering head through the cam grooves 17 and 19 and conveniently through the same pinion shaft 23 and for this purpose the ends of the rods 57 may be formed as piniens (it (see Figs. 2 and 7) and may be rocked by segments 6 pivoted on a collar or flange 63 carried by the shaft 11. and adapted to be operated by the levers 67 carryii cam rolls 69 and suitable cam means su' h as i will hereinafter describe may act on the can rolls 69 at proper times governed by the turning of the pinion shaft 23. Referring now more particularly to Figs. 2 3 and 7, I may mount a holder 71 on a sleeve or bushing 72 surrounding the end of the shaft it which may he provided with a dove tailed groove '73 (see Fig. 3) adapted to receive a corresponding rib on a slidable cam holder 7 conveniently of crescent or partly annular form to adapt it partly to embrace the shaft it as shown in Fig. The cam holder has an arm carrying a rack 77 meshing with the pinion shaft 23 preferably at the upper side thereof so as to be operated in opposite phase to the rack 23 controlling the numbering head.

Carried by the cam holder ronveniently at. the inner side thereof is a cam 79 shown by itself in Fig. l and which may embody a plate of partially annular shape conveniently provided on its inner circumference with a flange 31 (see Fig. 7) facilitating its support on the cam holder The inner face of the plate 79 carries two eamming elements disposed generally on opposite sides of the path of the cam roll69, an inner element 83, conveniently braced by-the rib 85. and an outer element 87. In the inner position of the cam holder the cam rolls or followers (55 miss the inner cam 83 but are forced inwardly by the cam 87 and the rods 57 are rocked to the position shown at the right and top of Fig. 6 wherein the types l9 are drawn inwardly to an inoperative position and will not cooperate with the impression cylinder 9. This is the normal position of the parts while the numbering ope-ration proceeds. hen, however, the pinion shaft 23 is rotated to shift the cam controlling the numbering heads so that a number isrepeated, the clockwise revolution of the shaft 23 viewing Fig. 3 will draw the cam holder 7 and its cam toward the right and the cam rolls 69 will then miss the cam 87 but will come in contact with the cam 83 which will cause the rods 57 to be rocked to the position shown at the bottom and left of Fig. 6 projecting the printing types 49 out to a printing position. When the serial printing of numbers is resumed, the cam holder is shifted back to the left and the cam element 87 acts to retract the printing types l9 again. In Figs. 3 and 6 we may imagine that this operation has just taken place and that the printing of a series of numbers is to re ommence after a half revolution of the printing couple. Before the cam was shifted all the printing types were at their outward position but the plungers shown at the top and left after having printed have now been acted. upon by the cam element 8? and are retracted. The type carried by the plunger shown at the bottom of Fig. 6 is about to print and after it has done so it also will be retracted; as will the plunger shown at the left After the series of numbers have been printed and the cam element 83 is brought into operative position to act on the cam roll 69, each plunger is moved to outward position substantially as it passes the three oclock position in Fig. 6 and prints as it reaches the six oclock position. i

I have described in detail the particular mechanical elements which are utilized in the embodiment of my invention here shown.
