PAPER-BAG-PRINTING MACHINE.

Specification of Letters Patent.

Patented Feb. 15, 1921.

Application filed November 22, 1919. 7 Serial No. 339,848.

To all whom it may concern Be it known that I, SAMUEL JOHN Hon TEAM, residing at New Toronto, in the county of York, in the Provinceot Ontario. Canada, have invented certain new and useful Improvements in Paper-Bag-Printing Machines, of which the following is the specification.

My invention relates to improvements in paper bag printing machines and the object of the invention is to devise simple means which may be adjusted to print any desired advertising matter upon the; paper as it is fed to the bag making machine and which may be readily adjusted so as to place such advertising matter in any desired location upon the paper according to the size of the bag which is formed from the paper by the.

bag machine, and also to provide means whereby the inking rolls may be readily separated so as to be set out of. contact one with the other when idle and thus prevent their deformation and further to provide means whereby a thorough distribution oi. the ink upon the ty e is effected and it consists essentially oi t e arrangement and construction of parts as hereinafter more particularly explained.

Figure 1 is a plan view of my paper bag printing machine. 1

Fig. 2 is a longitudinal section through Fig. 1.

Fig. 3 is a side elevation of my machine.

Fig. 1 is an enlarged perspective detail of r the means for clamping the type to the cylinder.

Fig. 5 is a detail showing the means for spacing the final inking rolls from the type.

Fig. 6 is a fragmentary plan view.

In the drawings like charactersof reference indicate various. parts in each figure.

1 indicates the'mainframe of my machine, the right hand portion of which is provided with upwardly extending hearing portions 2 and 3. land 5 areslideways in which are supportedbearing blocks 6 and 7. 8 is a shaft which is journaled in thebear ing blocks 6 and7. 9, is. my type-cylinder which is provided with hubs lO'xthrough which ertendsecuringscrews 11for scour: ing the type cylinderto the shaft 8 The type cylinder 9 is provided with a, series 0t longitudinal grooves. 12 which are preferably six in number, and? are arranged an e en i ance-apart 13 indicates my type plate which is segmental cylindrical in form and is provided at its ends with bevel portions 1 1 and 15. 16 and 17 are blocks which are slidably held in the groove 12, the end walls of the grooves being formed by plates 9. 18 are adjusting screws.

As will be seen byreferring to Fig. 4:, each adjusting screw is provided with an annular groove 19 located in that portion of the screw extending through the end wall: of the groove 12. 20 is a holding pinwhich extends downward from-the outer periphcry of the; plate 9. into the groove 19. 21 is almob secured to the outer end of each screw 18 and by which the screw may he turned by the operator. Each screw 18 er;- tends through a pair of blocks 16 and 17 so as to engage therewith. The inner end of each block 16 and 17 is provided with a notch 23 which engages the beveled ends of the type plate 13. The threads at the ends of the screws 18 are reversely set and by turning the screw 18 it willbe readily seen that the blocks are withdrawn. The type plate may be either withdrawn for renewal or adjusted. circumferentially to any desired extent.

It will be readily understood. that when large bags are being made up on the bag machine it would only be necessary to use one type plate 13, the impression being made upon the paper once in every revolution of the type cylinder, the paper required being equal in length to the circumference of the cylinder. j

when small sized bags are to he. made by the bag machine, that is to say, a bag half the length of the larger size, it will he necessary to have two impressions during each revolution of the type cylinder and for this condition I provide two type plates 13 as indicated in the drawings. If it is desired. to print upon a bagone-thirdthe size of the larger size then the type plateslii shown in the drawings are adjusted to the required position and an extra type plate inserted so that three type plates are spaced at, an equal distance around the type, cylinder.

2 1 isgan impression roll which is mounted upon a shaft 25.journaled in suitable bearings in the portions 2. and 3 of the main "Frame. The impression roll 24 is provided with a. suitable padding of paper 26 so as to give the required resistan to the type zine roll upon which the supply of paper is wound. Adjacent to the magazine roll 18 mounted a guidlng roller on standards 31. The paper 32 passes from the magazine 29 over the guiding roller 30 around the guiding roller 27 and over and around the roll 24- so as to pass between the impression roll and the type cylinder and from beneath the impression roll onward to tie bagmachine. The shaft 25 upon which the'impression roll 24 is mounted forms the main driving shaft of the machine, this shaft being ClllVQll from any Slllilikble' source of:

power. Upon one end of the shaft 25 is mounted a. gear 33. 34 1s a gear secured to the shaft 8 of the type cylinder. 36 are col larssecured to the shaft 8 in proximity to each end thereof, for a purpose which will hereinafter appear. 7

is the inking fountain of the machine. The fountain 35 comprises a base member 35 which is slidably supported in a suitable slideway 37 formed in the main frame'l of the machine. 38 and 39 are bearing standards which are provided with foot portions 40 having slots 41 therein through which extend securing screws 42 for adjustably securing the standards to the member 35*. i 43 is an inclined inking plate upon which the supply of ink is held. 44 is the main inking roll. 45 is the ink transferring roll. 46 and 47 are ink transferring and distributing rolls which co-act with the intermediate roll 48. Bearing upon the periphery ofthe roll 47 arerolls 49 and 50 which transfer the ink finally on to the type 13 of the type cylinder 9. 49 and 50 are the. spindles of the typerolls inking 49 and 50. The spin dies 49 and 5O project beyond the rolls 49 and 50 as indicated in Fig. 1 and are journaled in bars 52 which are pivotally supported intermediate of their length on pins 53 carried by the swinging bars 54 each of which is mounted upon a pin 55 carried in the main frame of the machine. In order to space the rolls 49 and 50 the exact distance from the type cylinder required so that the periphery thereof just touches the type as they revolve I have provided the spindles 49* and 50 with rollers 56 and 57 in contact with the collars 36 thereby definitely spacing the rolls 49 and 50 in position fromthe typecylinder.

The roll 48 is mounted upon a spindle 58 which projects beyond the end of theroll and is journaled in arms 59 and 60. The lower ends of the arms 59 and 60 are pivotally mounted in plates 61 and 62 carried by the standards 38 and 39 of the inking fountain. When the roller 48 is not in'use it is swung upward into the dotted position indicated in Fig. 2 so as to be out of contact with the ink distributing rolls 46 and 47. it has been found that where the inking rolls are left in contact that owing to their being formed of relatively soft material they will gradually become deformed by their own weight bearing against one another. F or this reason it is desirable when th rolls are not in use to hold them in a separated position.

Tn'order to se arate the ink distributin roll 47 from the rolls and 50 all that it is necessary to do is to slide the ink fountain outward upon the slide ways 37. By this movement the transferring roll 47 is carried out of contact with the rolls 49 and 50 andthe rolls 49 and 50 then drop downward out of contact with the type by gravity with the bars 54 on which they are carried.

I will now describe the means by which the ink is distributed longitudinally of the inking rolls. he distributing ink rolls 46 and 47 are mounted on spindles 63 and 64 which are free to move longitudinally in their bearings located in the standards 38 and 39. The distributing ink rolls 46 and 47 are reciprocated longitudinally in opposite directions by the following mecha nism. 65 and 66 are grooredwheels secured to the spindles 63 and 64. 67 is a standard bracket supported on one side of the machine and in which is supported a vertical rocking shaft 68. 69 is a cross arm carried by the upper end of the shaft 68 provided at the ends with forkmembcrs 70 and 71 the forks of which enter the grooves of the wheels 65 and 66. The stem of the members 70 and 71 are turnably held at their lower ends in the cross arm 69; The lower end of the rocking shaft 68 is provided with an arm 72 extending outward therefrom. 73 and 74 are gear wheels mounted upon spindles 63 and 64. 75 is a broad gear pinion mounted upon'the stud 76 and in mesh with the gears 73 and 74. The pinion 75 is driven from the gear wheel 34 by means of a gear wheel 7 7 mounted'upon the short shaft 78. The short shaft 78 is journaled in a beairng 80. carried on the side of the machine and is provided at its opposite end with a gear wheel 82 which is provided with a crank pin 83 (onnected by a link 84 to the outer end of the arm 72. 85 is a gear mounted upon a swinging bracket 86 secured to the side of the machine by a bolt 87. The gear 85 is in mesh with the gear 82 and gear 34 thereby completing the driving connection which is formed from the gear 34 through the gears 85 and 8:2 and shaft 78 connected to the gears 73 and 74 by the gear 77 secured to the opposite end of the shaft 78 and by the broad gear pinion 75 which is constantly in gear with the gears 73 and 74 carried by the spindles 63 and wheel 90.

(54 which are reciprocated longitudinally in opposite directions, the reciprocating action being provided for by means of the crank pin 83 and link 84 imparting a swinging movement to the arm 72. By this means the forks 70 and 71 are carried in opposite directions carrying the inking rolls 46 and 47 in a corresponding direction while in contact with the distributing ink rolls 48 and 49 and 50. This reciprocating action of the rolls 46 and 47 is to effect the spreading of the ink carried thereby longitudinally while revolving in contact with the rol1s'48 and 49 and 50.

88 is a shaft journaled in the bearing standards 38 and 39. 89 are arms secured to the shaft 88 at each end thereof. 90 is a ratchet wheel carried by the spindle of the main ink roll 44. 91 is a bar swung upon the spindle of the main ink roll 44. 92 is a link connecting the lower end of the bar 91 to the gear 7 7 eccentrically thereof. 93 is a pawl carried by the upper end of the bar 91 in engagement with the ratchet 94 is a detent carried by the shaft 88 and adapted to engage with the edge of the bar 91 when the lower end of the bar is swung toward the type cylinder. \Vhen the bar 91 is swung in this direction after the rotary movement of the main inking roll the ink transferring roll is carried into contact with the main ink roll against the tension of the spring 95. As soon as the bar 91 moves in the opposite direction the detent 94 is released'and the spring 95 acts to carry the ink transferring roll. 45 into contact with the ink distributing roll 46.

It will thus be seen from this description that I have provided a machine whereby suitable advertising matter may be printed on a bag of any standard size. To produce this result all that it is necessary to do is to loosen the plates 13 by turning the knobs 21 and respacing the plates apart around the type cylinder 9 in accordance with the size of the bag to be printed. If a large size bag is to be printed only one type plate is necessary on the cylinder, one impression being given during each revolution of the roll. If the bag to be made is half the size of the larger bag two type plates are arranged in the position indicated in the drawings so that two impressions are made during each revolution. If a bag a third the size of the larger bag is to be made then three type plates are arranged at an equal distance around the type cylinder, this operation being repeated until six plates are arranged around the cylinder for printing the smallest size bags. By my machine it will also be seen an even distribution of the ink is provided for which will absolutely prevent the blurring of the type andin which means are also provided for preventing the deformation of the inking rolls during the time the machine is standing idle.

lVhat I claim as my invention is:

In a paper bag printing machine, the combination with the main frame, of a type cylinder mounted in the main frame, an ink fountain provided with an ink roller slidably supported upon the main frame, and transferring rollers interposed between the ink fountain and the type cylinder brought into engagement with the type cylinder and ink roller of the fountain by sliding the ink fountain toward the type cylinder.
