CONTROLLING DEVICE FOR PRINTNG AYPARATUS.

Application filed April 2, 1926. Seria-1 No. 99,362.

This invention relates to improvements in controlling devices; especially controlling devices for printing apparatus.

An object of this invention is to provide a controlling device by which characters arranged in a certain order can be printed in a totally different order or succession, Without alteration of their arrangement in the printing apparatus which enables impressions ot such characters to be obtained.

A tnrther object of the invention is to provide a controlling device for printing mechanism in the form of a convenient and effective attachment `for said mechanism capable ot' being utilized whenever required without change of' structure of the printing mechanism. or even rcadjustment of the latter; so that when the controlling device is not in actual use, the printing apparatus can be employed in the regular and usual way.

Another object of the invention is to provide a controlling device for printing mechanism of such rconstruction as to be easy to handle and certain in operation, and still adapted to permit the printing apparat-us to give a comparatively large output.

Still ther objects and advantages of the invention are set forth in the following description, taken with the drawings; and the novel features are delined in the appended claims; but the disclosure is illustrative only, and I may vary the details of shape,

size and disposition of parts, without eX- ceeding the scope of the invention, as indicated by the broad and general meanings ot the terms in whichY the appended claims are expressed.

On said drawings,

Figure l is a top plan ot a controlling device according to my invention with the parts in starting position;

Figures and 3 are opposite end views thereof seen 'from the left and right,respec tively ot Figure l;

Figure l() is a bottom shown .in Figure 9; l

Figure ll is a front view; and Figure 12 a top plan of the device with the parts in final position;

Figurell is-an end view of the holder for the card or sheet to be printed, seen from theleft tl1ereoi,'as` shown in Figure 12; and

Figure ll isa `section on the line 14-,-14 ot Figure l2. Y

The same numerals identify the same parts throughout.

Referring to the particular construction shown in the drawings, I use the numeral l to indicate a base or support 1, which has the form of a flat plate of metal or any other suitable material. On the base is 'a carrier 2 in the form of a frame which bears a stencil or shield 3 in the formI of a' plate secured along one edge to one end' of the frame beyond one side of the basel lfor example, the upper side or edge with reference to the position of the parts shown in Figures` 1, 5 and 1Q. In practice', the'operators place will be adjacent-the oppositel edge ott the base fl to enable him to convenientlymanipw late the carrier 2 andthe other parts which the device comprises. The carrier movesl from one end ot the base l to the other, along a guide bar 4 and it carries with it not only the stencil 3, which-is fixed to the can` rier, but also a card holder 5 which is mounte ed in the carrier, so that it can be moved towards one side or the other of said carrier when this carrier is in its starting, middle or final position. The stencil plate has a slot therein shown at 6, and an aperture or open ing 7, the opening 6 being spaced from the opening 7. I also show at 8 in dotted lines, the position of a printing plate which will have characters thereon in the form .of letters, words and figures, 'and these characters can be reproduced in a different arrangementen the surface cfa card disposed in the holder 5 merely "1y exposing a part of these characters in succession through the openings 6` and 7. The printing plate 8 will be below the stencil 3 as shown in Figure 3, for instance. and between the stencil and thersurface of the plate bearingthe characters to be printed is a ribbon 9 similar to the ribbon ot' a typewriter so that when the card or sheet to be printed is pressed so as to force part of its surface against part of the surface of the ribbon which is exposed through plan of the part lll the opening 6 or 7. and that part of the ribbon against the characters on the plate 8. the desired effect on the surface of the card will be obtained. To this end,y I may make use ot a pressure roller .10 mounted upon a shatt 1l. as indicated in broken lines in Figures 2 and 3. This roller may be so controlled that it is depressed as required. and caused to act upon the card. so that the card makes contact with the portion of the ribbon eX- posed through the openings 6 or 7. according as either of these openings ma;vv be utilized. The printing plate S will. of course, be mounted in fixed position on a suitable support. and the roller l() majT be held and operated by means of any suitable mechanism to cause it to rise and tall. likewise to move back and forth if desired to a certain extent to pass over the full width of the openings 6 and 7. Machines which work with such plates 8 and ribbons 9 and contain pressure rollers 10. are in common use. and some of them are designated b v the term addressographs. They are employed for various purposes. such as the printing of index cards. etc.. and need not be further described here. as mv invention relates simplv to a controlling device to be used with such a machine bv securinfr it to the fiat top or trame-work thereot` in position to cooperate with the plate 8 and ribbon fl. and enable the roller 10 forming a part of such machine to be employed in the ordinary way.

The carrier 2 has the form shown in Figures 1. 5 and 1Q. tor example. and is approximatelv U-shaped. the ends ot the arms thereot terminating in bearings i2 through `which the bar 4 passes. so that the carrier ean slide easilx7 along this bar. Adjacent the opposite edge of the base l, it is provided with rollers 13 to support it above the surface of the base. and enable it to more easilv trom one end thereof to the other. Starting at the lett. with reference to Figure l.. the movement ot the carrier Q with the stencil 3 and card holder 5 will be in a straight line until nearlxy the opposite end oi the base is reached. rllhen. as will be more full)7 described later. a slight lateral movement takes place also before, the movement longitudinali)7 ot the base l is finished. For this purpose. the bar It is mounted. so that it can swing to the required extent away trom the adjacent edge of the base 1. It is, theretore. mounted in bearings at the upper ends of links 14, journaled upon a bar 15 below the bar 4 supported in bearings 1G rigid with the base 1. Hence. when a force is eX- erted sidewise of the bar 4. it can swing outward away from the adjacent edge of the base l to a certain extent and draw the carrier 2 with the stencil 3 and card holder 5 with it.

Adjacent the end ot the base from which the carrier starts is a diagonal slot in the base l which receives an adjustable gauge or stop 18 which 'an be secured at variousl positions in the slot. On the top of thc base adjacent the .slot is a calibrated scale indicated at lf). to indicate the positions which the stop 1S is to assume under various con ditions. 'lhis .stop marks the limit l'or the carrier 2 at one end of' the base l. and its movement at the other end i.s terminated b v a stop 2t) in the form of an adjustable .screw in a bearing 2l. which can bc held in position by a lock uut 22. One .side of the carricr has a jnojcction :Z3 to enable the operator to seize it between thumb and finger. and move the carrier towards the stop 1S. The carrier is actuated to travel towards` the stop Qt) bj' means ot a spring Q4 in the .bar 4. the latter being hollow to receive thi.s spring. One end ot the spring is .secured inside the bar el, and the other end is attached to a. pin Q5 in the bar l but fixed to one ot the bearings i2. preferably, the bearing beneath the projection 23. As indicated in Figure l, this bearing may hare a projection 2G extending through a .slot 2T in the bottom ot the bar or guide l. and to this projection 2li. thc pin '.25 may be .secured in an)v suitable wav. Hence, when the carrier is not held against movement. the .sprintr 2l will act to draw it to the right: until it encounters the .stop 20.

I shall now describe the construction of the card holder 5 which is movablv mounted in the carrier 'lhis card holder comprises a plate 2S along the sidcs of which are upturned fliinges 29. The plate Q8 extends from the stencil Il across the base almost as far as the bar it. and at its corners adjacent the bar el it has upturned perforated lugs forming bearings 30 on the sides of the carrier Q in line with these bearings il() arc lugs 3l which are perforated to receive the end:s ot a guide-bar 32 passing' through the bearings 3f). and the holder 5 can thu.s .slide in one direction or another. along the bar 339. A binding screw li mounted in om` of the lugs ill engages the bar 3Q. and hold,s it against displacement 'lhe bearing 2l() at the right in Figures 5 and .l` is .shown as provided with a jirojcction Ill. similar to the projection 2li. to enable the operator to .seize the card holder and move it. Almtting the. opposite' bearing 3f) is a spring 35 coiled around the guide-har 92 and attached to this bar at its opposite end by means of an anchoringr screw 3G. This spring tends to impe] the card holder towards the .side of thc frame at which is located the projec tion Q3.

Rigid with our` ot the flanges 20 at the right. of the card holder 5 is a` guide projection 37 which slides through a bearingr opening 38 in one side ot the carrier i2. The card holder also carries a movable arm or pressure member 3f) which can be raised loo llt)

lill! and then moved downy on top of a card or sheet of material to be printed, placed in the holder, to secure this spring or sheet in operative position. This arm 39 is mounted upon a pivot 40, the arm being movable up and down about this pivot, and this pivot- 40 is secured to af swivel 41, engaging a bearing in a projection 42, which is part of the thickened edge` 48 ot the plate 28 beneath theguide bar 32. The portion of the plate 28 adjacent the guide-bar 82 is more elevated than the remainder of the plate 28, as indicated at 44, and beneath this raised portion 44 is a transverse connecting bar 45 which joins the two sides of the carrier 2. Resting upon this portion 44 is the liange 46 of a plate 47 which is disposed between the flanges 29 on top of the plate 28, this plate 47 having two openings 48 therein, and being shouldered at 49. Thus a card of some width can be placed in the holder 5, one edge abutting the shoulder 49, and the other edge lying upon the stencil 3. A similar shoulder may extend across the card holder joining the principal part of the plate 28 to the portion 44. The extension 46 has slots 50 therein, and the holder 5 carriers threaded studs 51 which pass through these slots and bear binding nuts 52. By loosening these binding nuts, the plate 47 can be moved towards or from the stencil 3 and fastened in position by the nuts 52. The edge of the plate 47 adjacent the stencil 3 provides a shoulder 53 so that if a card or strip of relatively narrow width is to be printed, it is laid in the holder 5 with one edge abutting the shoulder 58, and the other edge over the stencil 8, and the arm 39 will serve as before to clamp this strip in place. The swivel 41 permits the arm to be swung from side to side as this swivel can be rotated in the holder 5; while the pivot pin 41 permits the arm to be lowered and lifted. A spring may be employed in connection with the pivot pin 41 to move the arm 89 downward and keep it pressed upon the card Vor the like, inthe holder 5.

The left side of the carrier 2 is provided with a slot 54, through which projects a stop 55 attached to the adjustable gauge or stop 18. This stop is in the form of a pin which passes through a bore in the stop 18, and it can be adaj usted and held in adjusted position by means of a binding screw 56, and when secured in place, this stop 55 marks the limit of the movement of the holder 5 to the lett on the base 1. The stop or gauge 1.8 has a pointed or index projection 57 to enable itV to be accurately located with rc* spect to the marks on the scale 19, and it is made up ot two members 58 and 59, one above the base and one below it, each ot these members having guide projections 60 which enter the slot 17. Through the two members 58 and 59 extends a hole 61, the hole, in the bottom member 59 being threaded, and a headed binding screw 62 secures the two members together. l lhen one desires to move. this gauge in the slot 17, the screw is loosened to enable the members to slide in the slot and then tightened to hold it at the point desired. Further, this gauge 18 carries a pivoted catch 68 mountedon a pin 64. The catch 63 is in the formell a bell crank lever, one end ot' which entends :into an aperture 65 in the member 58, but loosely, so that the other arm ol' the catch which is horizontal can be raised. 'Theend ot this arm has a shoulder 66 thereon, to serve as a hook, and a projection 67 tor the finger of the operator to raise this catch. Ordinarily, the catch will drop by its own weight to hold the carrier 2 in a position shown in Figure 5 by the shoulder 66 engaging the top edge of the side ot the carrier 2. But when'this catch is litted by the operator pressing with his thumb onthe projection 67, the carrier is liberated, as the catch then clears the edge 68 of the carrier 2. n To check the holder 5 at a predetermined point` when it moves with the carrier 2 as i'ar as the catch 63 permits the latter, I mount below the base 1, a movable stop which projects through an opening 69, a slightdistance above the top surface of the base 1. The end of the catch which so projects is indicated at 70 and this end is the upturned extremity of a bar 71 disposedv beneath the base 1 and attached by screws 72 to an arm 7 8, pivoted on a pin 74, mounted in bearings or lugs 75. This catch is best shown in Figure 7. Encircling the pivot 74 is a spring 76 which engages the down-turned front edge of the base 1 and the lower tace ot the arm 78, so as to urge this arm upward and make the end 7 0 project through the opening 69. Carried by the arm or lever 7 3 is a pair of perforated bearings 77, similar to the bearings 75, and mounting a similar pin or journal 74 on which rotates a roller 78. The screws 72 pass through slots 79 in the bar 71 and engage threaded holes in the arm 73, so that' by the loosening ot the screws, the slots` 79 permit the longitudinal adjustment ot the bar 71. The base 1 has slots 8() which expose the slots 79, so that. the heads ol the screws can be disposed in these slots below the'level ot the top surtace o't the base 1. As indicated in Figure 6, the roller 78 projects above the top of the base` 1 through an opening 81. and when this roller is depressed as indicated in Figure 11. the catch compris ing the upturned end 70 ot the bar 71 is depressed, so as to withdraw the stop 70 from the opening 69 and then permit the holder 5 to move farther to the right when the carrier is urged to its i'inal position.

On the top surface ot the base 1 just bcyond the aperture 81 towards the right of the base, I aix a cam piece 82 having an lll() til incline or diagonally extending edge 83. This piece is secured to the top of the base l hv 'fastening means such as screws Sli. The adjacent side ot the carrier 2 has on its lower t'ace a projection S5. in line with the crosshar 45. and when this carrier has traveled 'liar enough to the right. to cause the projection .Q5 to engage the dia f fonall}v extending edge Si?, ot the piece S2. a transverse movement ot' the carrier swinging the guide 4 outward on the links 14 must occur. To gire clearance tor the piece the adjacent side ot thc carrier 2 between the crossbar 45 and the roller lil on that side. is av little distance above the base l. as indicated in Figure 3. The purpose ot' this transverse movement will be described later.

As indicated b v the numeral SG. the bar 4.5 is not straight but has a bend therein adjacent the side engaged by the catch G3. On the lower tace of this bar is a downward extending rib indicated at 87 running along the edge which is presented towards the stencil plate 3. and between the bend SG and the right end ot this bar. this rib has a diagonal surtace or section SS. Then the carrier mores. this rib ST runs in contact with a roller S9 mounted on a pivot bolt 90 which holds it` in horizontal position on the upper tace ot the base l. As indicated in Figures T and S. the pivot holt 90 passes through the base and screw threads into a link Q1 below the base pivotallj7 held in place hr a rivet 92. This link can be moved from side to side to adjust the roller towards and trom the rib ST. A binding screw 93 passes through a sloty 9i in the base l. and screw threads into the opposite end ot the link 91. Hence. by tightening this binding screw. the link can be locked in the desired. position. Isimilar slot 94 through which the pivot bolt 90 passes allows mmement of this holty and the roller S9 when the link and roller are to be adjusted. The roller 89 by engaging the rib 87 prevents movement ot the carrier. the holder and the stencil 3 h v swinging the guide 4: outward on the. links 14: until thev cam piece engages the projection 85. The roller .Q9 so mounted that this roller :Aimuitamouslv reaches the diagonal surface or portion SS ot the rib S7. and this roller then does not hinder the sidewise movementJ ot the trame, but cooperates with the cam edge S3.

As stated above.` the flanges 29 do not eX- tend entircljv along the sides ot the card holder 5. hut terminate adjacent the slioulder which runs along the edge ot the raised portion 114. On the top ot this portion adjacent the swivel 470. l secure by a hinge. a. member 95. The hinge for this member is shown aty 96. and it may comprise a spring 97 to press down upon the member 95. and hold it flat against the top ot the part it of the card holder. At its tree end, the me1nber 05 has a down-turned end 98 which depends far enough to he in line with the end ot the stop when the gauge t8 is mored tar enough along the slot 'li' to briner the stop into position to strike the. downturned end 9S ol this member. When the holder 5 is pushed to the lett as tar as it will go in the carrier the end 0S ol' the men'iber 95 clears the side ot the cross-bar l5. and dropsl as low as the top of the plate '178: but as soon as the holder moves in the carrier. Vt'ar enough to bring the down-t urned end 9S ot the member Sla into engagement with the hend Sti. the top ol the bar at this bend will lift the member For this purpose. the upper surface ot the har at the bend SG mav be rounded to enable it to have the desired etl`eet on the member 95. rllhe rib Si' l'ollows the contour of the bend .Qt and when the rib at the bend comes into engagement with thc roller 8f). the carrier does notl more an)v further to thc right, out then occupies its tiual position as Figure. '1Q shows. with the carrier abutting the stop screw 2t).

.l may arrange in one ol the links 111. a stop screw 99 which ma)v ahut the downturned l'ront edge l0() ot the hase l. to limit the swinging movement ot the guidivt towards the hase. and l may also reces;` the hase in the middle alongthe edge adjacent the stencil 3 as indicated by the numeral lOl directly7 adjacent the printing plate S.

In operation. suppose it be (le-'ired to print the matter which appears upon the upper tace ot the plate 8 below the stencil 3. but to change the order or succession in which the parts ot such mattei' appear. Let it tirst be assumed that certain words or characters are on the upper tace ot the plate 9. as indicated by the nun'ierals l. ll. and lll. and that it is desired to revere the order ot' Group I and Group ll. and to print the words made up b v the charm-ters of Group lll not under Groups I and ll. hut to one side or in line with same. l proceed bj.' tirst putting a card in the holder 5. clan'ipiug it in place by the arm 3f). This card is shown in dot and dash lines and is indicated b r the numeral 10Q. lt is illustrated as extending from the shoulder 53 out' over the open ing"v G and 7. The operator then takes hold ot the projection Q3. and forces the carrier to the right unt-il it strikes the gauge i8. The stencil 3 now moves with it. and so does the card holder 5. until this holder ahuts the stop Now the stencil covers` Group l. but exposes the characters making up the numbers. or words. or both7 of Group ll through the opening Holding the device in this position. the operator now causes the roller l0 to descend to press part ot its surface against the card, so as to torce the portion ot the card over the opening 6 against, the ribbon t), and this ribbon against the printing plate 8. f Group II is then forced to make an impression against the card 102.

The next position is the position of the parts shown in Figure 5. This position is attained merely by releasing the carrier so that the spring 24 in the guide 4 pulls it to the right as far as the catch 63 permits. The

voperator now lays uhold of the. projection 34 and forces vthe card holder 5 to the right against the stop 70. The stencil 8 now lies in such position that Group I is exposed; while Group II is covered up, and the card upon which Group II has been printed near the right end has been carried so far past the printing plate, that the impression of Group II on this card is in advance of Group I, but in line with it. Holding to the projection 34, the operator again makes the roller 11 descend and Group I isnow made to give an impression in its turn on the lower face of the card 10Q. The two'impressions are in line with each other, along the top edge of the card, but are reversed with respect to the order of Group I and Group II on the plate 8. When the card is taken out and turned over, the right edge in Figures 1 and 5 then becomes the left edge, and the` matter `printed upon it is of course read from left to right in the usual way. If, for example, Group Ion the printing plate reads Joseph and Group II should read Bowles, B 800, the order in which these words and numbers would appear ,on the card after printing is Bowles70B 800 Joseph.

To complete the operation and obtain an impression of the characters making up the words or numbers or both of Group III on the printing plate 8, the parts arecaused to assume the positions indicated in Figures 11 and 12. For this purpose the operator presses his thumb against the projection 67 to lift the catch63. Spring 24: then actuates the carrier 2 to move a little bit farther. Before lifting the catch `63, the projection 34 isf released, so that the holder 5 is not held against the stop 70 when the spring 35can force the holder 5 to the left a little. The carrier then travels `far enough to engage and depress .the portion of the roller 78 projecting through the opening 81, so as to remove the stop 70ffrom. the path of the holder 5. Next, the projection 85 strikes the cam edge 83 andthe carrier with the plate 3 and holder 5 moves laterally, the guide 4 swinging outward as above stated.` This movement brings the card-102 in such position that the impressions which it has received from Groups I and II arenow to the right of the plate 8, and have cleared same, and opening 7 of the plate 3 has come into position to expose Group III which heretofore in the positions of the parts shown in Figures 1 and 5 have been entirely covered by the stencil 3. At the same time,` the movement of the parts transverse of the base have drawn the card `102 with them, so as to bring the impressions received from Groups I and II in lateral alinement with the top row of characters of Group III. As shown, the opening 7 is somewhat largerfthan the opening 6, and upon roller 10 .again being depressed, an impression is obtained from Group III on the card and this impression is not below the impressions of Groups I and II, but on the same line unless, of course, the words or numbers, or both, formed by the characters of Group III take up more than one line. The order of the parts of Group III is not changed, but the position of this whole group with respect to Groups I and II is changed. The characters of Group III may set forth the address, occupation, and other fact-s concerning the person whose name is being index-ed.

The recess 101 is provided for the convenient removal `of the vprinting plate `8 which in machines of the type for which my invention is designed, is displaced by moving it forward out of the machine in the direction of the guide 4.

The gauge 18 and slot 17 are provided so that the position of theparts adjacent the left of the base 1 can be accurately obtained according to the number of characters in Group I which is Lto `be covered when the stencil iirst exposes Group II `through the opening 6. If Group I presents the first name of a person of say eight characters,

the index projection 57 of the gauge and stop 18 should preferably be opposite the numeral 8 cnthe scale and for long names, meaning that Group I contains more characters, the gauge is simply moved along the slot opposite the higher numbers of the scale. Where thegauge is adjacent the lower numbers, the stop 55 would not strike the adjacent flange 29 of the holder 5, because this flange does not extend far enough towards the cross-bar 4:5. Hence, I provide the member with the down-turned end 98 to abut against this stop when the conditions of work are such that the gauge must be located adjacent the lower numbers on the i scale, for proper results.
