PRINTING MACHINE Filed Dec. 18. 1930 3 Sheets-Sheet 3 Patented Oct. 17, 1933 I FIYCE- UNITED STATES PATENT OF Claims. (01.101-58) This-invention relates to printingmaoh-ines and more especially to a selector for such machines of the character through'which variable printing devices are sequentially Passed from which printing impressions are made.

The salient object of myinvention is to pro vide a novel selector for determining whether or not impressions are to be made from the printing devices passed through the machine. The selection or determination of the printing de vices is usually controlled by suitable means on the printing devices such as removable tabs, notches, openings, or the like. However, the size oi the printing devices is usually limited-andthe number of such determining'means that can be provided. is consequently limited. In the art, eachof such means is known as a primary selection and the selection may be determined from any oneof these means or from a grouppof such means. However, groupseleotions are of course dependent upon the number of primary selections; and it is therefore an important object of my invention to provide a selector having a large number of primary selections; i V

A further object is to provide a selector which may be readily associated with any of the various types of "printing machines already in use or in newly constructed machines.

' A still; further object is to arrange J chine in' which certain parts are broken away;

Fig. 5 is a transverse sectional viewtaken substantially on the line 55 on Fig. 4; r

Fig. 6 is an elevational view of one of the rinting devices employed in the machine; and' Figs. 7, 8, 9, and 10 are perspective views of" the removable tabs employed in the device;

In the accompanying drawings 'I'have'iragmentarily illustrated a printing. machine which may be, for example, of the character disclosed; in my co-pending application, Serial'No. 451,812,; filed May 12'; 1930. The machine as disclosed inthat application and in the accompanying draw-1 ings includes a. frame. 11 in which the main drivezrocker' 12 is pivotally mountedat 131 A reciprocatory-movement is imparted to'this main the deter-- mining means on removable tabs in such a man- Fig-.4is a fragmentary plan view of'the ma} drive rocker 12, which, in turn, is transmitted through the link 14 to the printing device feed arrangements including the rocker15 pivotally.

mounted ontheframe at 16, the link'14 being. pivotally connected-to the main drive rocker 12 at 17 and to the rocker 15 at 18. The printing. devices Dare introduced into a magazine M and are successively withdrawn therefrom and passed along the printing device guideway 19 by the pawls 20 suitably mounted on the printing device feed slide bar 21. An arm' 22 depends from the frame 11 and pivotally mounted thereon is, a rocker 23 connected through a link 24 to the slide bar 21. The rocker 23 is connected through a link 25 to the rocker 15 and therefore when the main drive rocker '12 is reciprocated. movement is transmitted-to the bar21 to impart a step-by step movement to the printingdevices. D so that the printing devices will movethrough selecting positionin the machine wherein the printing device 1) is shown and into printing position above the anvil 26 wherein the printing deviceD is shown.

Pivotally mounted on the frame 11 in alignment with the pivotal mounting 16 of the rocker 15 is a,stamperar1n27,at theouter end of which the platen P is adjustably mounted.- stamperarm includes a depending arm 28 having a roller 29, rotatably mounted at the lowett. end thereof that is movable in the channel 30v at the lower end of the rocker 31 pivotally mounted on, the same center as the pivotal mounting 1 3 forthcdrive rocker 12. Q11 the rocker;3l,is a

' pad 32against which the end of. a. pawl; 33 is normally abutted,. the pawl 33 being pivotally mounted on the-main'drive rocker 12 at 34. As

gages the same during each reciprocation of the rocker 12 to urge the rocker- 31 into the position illustrated in Fig. 2, this occurring when the The main drive rocker 12 moves in a counter-clock-1 wise direction as viewed in Fig. 2. When, how-5 ever, the maindriverocker '12 is moved in* a clockwise direction, as viewed in Fig. 2, the"; pawl 33 engages the pad 32 and imparts movement. to

the rocker, 31 and therefore the. channel. 30,

which is in thenature of acam groove and actson the rol1er-29 -to.move the depending arm 28- and' consequently the Stamper arm 27 to move the platen P-toward the anvil 26, and an-impression is made from the printing device D througha suitable ink ribbon (not shown). .,It is therefore manifest that downward orv printing movement of the platen P depends upon the en-;'

' plate 49, the arm 41 will be held in an upper In the upper surface of the pawl 33 there is a recess 35 and at one end of this recess a shoulder 36 is defined. Journaled in the main frame 11 is a shaft 37 having an arm 38 thereon carrying a roller 39 which may be disposed in the recess 1 35, as illustrated in Figs. 1 and 2, when the pawl 33 engages the pad 32, but when'theroller39 moves onto the shoulder 36 thepawl 33 is pivoted about the pivotal mounting 34 thereof against the action of the spring 40 and is disposed out of the path of the pad 32. Also fixed on the shaft 37 is a bell crank including an arm 41 and an arm 42. The spring 43 is connected to the arm 42 and to'a spring anchor on the frame 11, and this spring acts on the bell crank to urgethe arm 41 in counter-clockwise direction as viewed in Fig, 1. Movement of the arm 1 41 is limited lay-engagement thereof with a pin 42 on the arm 43 of the rocker, generally indicated by 44, V pivotally. mounted at 45 on the bracket 46. Also mounted on the'bracket 46 is the rocking member 47 having plates 48 and 49 thereon between which a recess 50 is defined, Adjacent the rocking, member 47 is an arm 51 having a recess'52 therein and a shoulder 54 is defined at one end of the recess 53. One end of therod 55 ismovable into the recess 53 or'onto the-shoulder 54 and when disposed on the shoulder 54 the'rockingmember '47, which is connected to the arm 51 through the spring 56, is disposed in the position illustrated in Fig. 2. Pivotally mounted at 57 on'the rocker 15 is a pawl 58'havi'ng a nose 59 engageable with the plate '60 on the arm 61 0f the rocker 44. When the rocker 151s moved in the manner previously described the nose 59 of the pawl 58 engages the plate and pivots the rocker 44 to move the pin 42 upwardly from the position illustrated in Fig. 1so that said pin 'will'be disposed out of the recess 50. In a manner to be described the rocking member .47 is positioned so that either the plate 48 'or 49 or the recess 50 will be'positioned below the pin 42 after movement thereof out of the-recess 50. Wherithe nose 59- disengages the" plate 60 the rocker 44 pivots in a clockwisedirection'and the pin 42 moves downwardly. Should the pin 42 move-into the recess'50 the arm 41 will move downwardly'and the roller 39 will be disposed in the recess 35. However, should the pin 42 come to rest on either the plate 48 or the position and the roller 39 will be disposed on the shoulder 36' and the pawlf33 will not engage the plate 32 and consequently no movement will be imparted to the rocker 31. On the rocker 15" there is a-pawl 62, the nose of which is engageable with a plate 63 on the rocker 64 pivotally mounted on the shaft 65 journal'ed in the frame 11'. Also mounted on the shaft 65 and on the. shaft 65' is'the'selector' bar structure'66 and a' spring 67 is interposed between the structure 66 and the rocker 64. A plate 68'carried by the bar 70 is movable downwardlyv in a certain amount to be described presently and engagesthe upper end of the rod 55 to move the same'and thereby position the rocking -mernber 47 as previously described. The selector bar structure. carries the bar 70 in which a'plurality of transversely and longitudinally aligned openings are provided into which pins 71 may be introduced when'the removable plate '72 (Figs. 3 and 4) is removed. The'positioning of the pins 71in certain of the openings in the bar 70 will be described'more' fully presently. Disposed .below the plane oi. the plate guideway 19 is a block 73 which has .a

plurality of transversely and longitudinally aligned openings therein positioned correspondingly to the openingsfin the bar 70.

The printing device D in selecting position has; detachable tabs -T connected along one edge thereof, which tabs may be held in a position in the manner set forth in the patent of H. E. HubbardNo. 1,677,449, patented July 17, 1928.

'The tabs T are illustrated in detail in Figs. 7

to 10, inclusive, and these tabs include body portions which project beyond the edge of the printing device when the tabs are installed in position, this being clearly illustrated in Fig. 6. On these tabs the detecting means are in the form of embossages or protuberances. These protuberances are, in the present instance, embossed at any of four different positions on the body portions of the tabs. In'Fig."7 the pro-' tuberance A is embossed on the body portion of the tab T adjacent the upper right hand corner thereof. In Fig. 8 the protuberance B is'shown on the body portion of the tab adjacent the upper left hand corner thereof.- In Fig. 9 the protuberance C is shown on the body portion of the tab adjacent the lower right hand corner thereof. And inFig. 10 the protuberance D is shown on thebody portion of the tab adjacent the lower left hand corner thereof. The determination of the selection results from the disposition of the embossages or protuberances A, B, C, and D on the tabs T, which tabs T in turn are disposed at various positions along the edge of the printing device. In the present embodiment, of-the invention the printing device is arranged to have twelve" such tabs T secured thereto and since each of the tabs may be provided with an embossage at any of four difi'erent' positions'it is manifest that I am enabled to thereby attain forty-eight primary selections.

twelve tabs, this merely being exemplary-of the invention.

It has; been pointed out that the pins 71 are 7 arranged in two rows in transverse and in longitudinal'alignment. The pins 71 in one transverse row will be aligned with the protuberances positioned similarly to the protuberances A and;

B, while the pins in the other transverse row will be aligned with protuberances positioned similarly :to. the protuberances C and D. The spacing apart of the pins in the tworows just described corresponds to the spacing apart ofthe protuberances A and B, and C and D; and

since, for example, the protuberances A- and'C,

and B and-D will be in alignment on the tabs, it is manifest that the pins 71 will be similarly aligned. a a g I 1 An example of use of the device may be that a tab T might .be positioned as indicated by 74 in'Fig.- 6 with a protuberance A thereon. If only printing devices. having a'tab at such a position with a protuberance A thereon were to be printed, for example, a pinf71 would be 'd'isposed at this position. Therefore, when the' main drive rocker 12 is set in motion and movement is imparted to therocker 15, u1e rocker 64 will be moved which. will movezth'e structure 66.downwardly, 'this movement being transmitted. through the. spring. 67' and if the printing .de-' vice D has'a Itab'at. 74 thereon with a protuberance A, the pin '71 will strike this protuberance and will hold the bar 70 against movement and therefore the plate 69 will not move the plate 68, and thus the pin 42 will move into the recess 50 to consequently allow thepawl 33 to engage, .the pad 32 and thus the platen P will be moved ance A thereon, the pin 71 will manifestly not strike such a protuberance and therefore the bar '70 will move in an amount greater than' the first movement, and the plate 69 will act on the plate 68 which will engage the rod 55 and move the same downwardly and in the present instance the plate 48 will be disposed below the pin 42 which will be held in an upper position and therefore the pawl 33 will not engage the pad 32 and thus no movement will be imparted to'the platen P.

An example of a group selection may be that a printing device having tabs positioned as indicated in Fig. 6 might be used and only printing devices having tabs and protuberances as illustrated in Fig. 6 will be printed. I have stated that the positions A, B, C, and D of the protuberances indicate the primary selections, but it is manifest that a tab might be provided with more than one protuberance which, in itself, would constitute a group. Such a tab is indicated in the position '75 in Fig. 6, and this tab T has protuberances B and C thereon.

When printing devices such as those illustrated in Fig. dare to be printed with the machine arranged as previously described, the pins 71 will be disposed to correspond to the positions of the protuberances on the tabs at the positions illustrated. Therefora'when these pins strike these protuberances a printing operation will be performed as previously described. Should these pins fail to strike the protuberances the printing device will be skipped.

In the foregoing description I have describeda selection as being performed to print print-'- ing devices tabbed only in a certain manner, but as is well understood in the art this arrangement might be reversed and printing devices tabbed in a certain manner would be skipped, while all others would be printed,

In the foregoing description I have described a selected embodiment of my invention but it is to be understood that this is capable of variation and modification and I therefore do not wish to be limited to the precise details set forth but desire to availmyself of such changes and alterations as fall within the purview of the following claims:
