PRINTING-MACHINE.

To all whom t may concern Be it known that we, -HARoLD ALBERT RICE and CHARLES GEORGE PATTERsoN, both of the city of Toronto, in the county of York and Province of Ontario, Dominion ot' Canada, have invented certain new and useful Improvements in Printing-Machines; and we hereby declare that the following is a full, clear, and exact description of the same.

Our invention relates to a printing machine in which the paper is automatically printed as it is manually drawn from the roll, and the Objects ofl our invention are: (a) to mount the printing cylinder, platen and paper roll so that they can be unitedly moved to and from their working position without disturbing their working relation whereby the printing Aof the paper can be effected, or convenient access may be had to the printing mechanism when changing the type bands, recharging the inking roll, or threading the paper around the platen; (b) to provide these parts with a locking mechanism which will securely hold them in their working position or when moved therefrom; (c) to provide the printing cylinder with a sliding movement whereby it will engage the platen when in its working position, and will automatically move away from the platen when moved from its working position; (d) to provide the paper with a tension roll which will maintain a continuous contact withthe paper roll and automatically follow the decreasing diameter of the paper roll as the paper is withdrawn therefrom.

Figure 1, is a front sectional elevation of the printing machine showing the structural character and relative position of the parts; n

Fig. 2, is a plan view, with the cabinet top removed, of the parts shown in Fig. 1;' Fig. 3, is a vertical sectional elevation from the right of Fig. 1, showing the parts in their working position; Fig. 4, is a similar view to Fig. 3, showing the paper knife and tensioning means in their elevated position; Fig. 5, is al vertical section on the line awa Fig. 2, with the parts in the position shown in Fig. 3; Fig. 6, is a vertical section on the line b-Z) Fig. Q, from the same end-of the machine as Fig. 3, showing the parts'in their tilted position; Fig. 7, isa sectional elevation from the lett side of the machine, with Specification of Letters Patent.

Patented June 30, 1914i.. serial No. 770,013.

the parts in their working position, as shown 1n Fig. 3; Fig. 8, is a detail View of the looking members from the opposite side to that shown in Fig. 7; Fig. 9, is an end velevation of the parts shown in Fig. 8; Fig. 10, 1s a perspective view of the machine with the cabinet top removed; and, Fig. 1l, is a perspective section of the printing cylinder.

Like characters of reference refer to like parts throughout the specifications and drawings.

It is optional whether we use a cabinet or not, but it is found advisable for protective purposes to provide the apparatus with a cover which will prevent interference with the printing cylinder, inking rolls, their related parts, and the paper,- during the ordinary `use of the machine, and for that reason we have shown in the accompanying ,drawmgs, a cabinet comprising a base l and a superstructure 2 of .suitable dimensions to accommodate the working parts of the apparatus.

Secured to the base 1 are standards 5, 5a, in which are oscillatingly mounted the arbors 6, 6"L of the side plates 7 forming part of the main frame of the machine, the side plates 7 being suitably connected together by spacing bolts 7a, 7b, and a bottom plate 7c. The arbor 6a is formed with an enlargement 8 having two locking grooves 9, .92"

to receive the locking bolt 10 which `holds the apparatus in its working and tilted posit-ions.

The locking bolt l0 is movable in. a. slideway 11 and is apertured at 10a to receive the lever 12 fulcrumed at 13 to the standard 5a.

Connected to the standard 5a is a springl4 bearing against the locking bolt 10 to hold it in the locking groove with which, for the time being, it has locking relation.

The arbor enlargement 8 is provided with stops 15, 15a in juxtaposition to the locking grooves 9, 9ft respectively, these stops 15, 15a engaging the slideway 11 during their oscillation to limit the rotation of the side plates 7 and their related parts, and bring therespective grooves 9, Quinto position to register with the locking bolt 10.

When the parts are in their working position, as shown in Figs. 2, 3, 5 and 7, thestop 15 is in engagement with they slideway -11 andthe locking bolt 10 is then entered in the locking groove 9, the spring 14 holding the locking bolt in its locking engagement therein.

To tilt the main frame and its related parts from the position shown in Figs. 2, 3, and 7 to that shown in Fig. 6, the handle end of the lever 12 is raised and thismovement of the' lever causes its other end to depress the locking bolt and Withdraw it from the locking groove 9. The main frame and the parts carried thereby can then tilt from the position shown in Figs. 2, 3, 5 and 7 yto that shown in Fig. 6 and when the parts have reached their limit of movement, the stop 15a comes into engagement with the slideway 11, and brings thelocking groove 9a into position to receive the locking bolt 10 which secures the apparatus in its tilted position until it is again released by the operation of the lever 12.

J ournaled in the side plates 7 are the arbors 16a of the revoluble'platen 16, and journaled in the side plates 7 above the platen, is the shaft 17, to which the printing cylinder 18 is iixedly connected, the printing cylinder having tires 18*L engaging the paper passing over the platen and effecting its revolution.

Loosel mounted on the shaft 17 at the ends of the cylinder 18 are the journal plates 19 formin part of the frame for the inking and distri uting rolls, and connecting the journal plates 19 is a cross bar 20, to which 1s pivoted` an arm 21 having at its free end forks 22 to engage with the spacing bolt 7a, the cross bar 2O being provided with a'stop 23 to limit the movement of the arm 21. Attached to the arm 21 and to the cross bar 20 is a sprin 24 which draws the arm 21 into and holds it in engagement with the stop 23.

The journal plates 19 are slotted to re-` ceive the arbors 25 and 26 of the inking roll 27 and distributing roll 28, and holding the inking `and distributing rolls in contact with each other and with the printing cylinder 18, are springs 29 and 30. The printing c linder 18 is provided with removable type ands 31 having at their ends fasteners 32 engaging with corresponding fasteners 33 secured to the rinting cylinder 18, as shown in Fig. 11 ofp the drawings, by means ,of which, the type bands 31 can be quickly and conveniently removedand replaced when changing or renewing thetype. The fasteners 33 preferably extend completely across' the printing surface of the printing cylinder 18 so that the type bands 31 may be conveniently set at any selected position thereon.

Between the type bands 31 and the rinting cylinder 18 is a cushion 34 preferably of sponge rubber which by reason of its comressibility compensates for any unevenness 1n the thickness of the type bands, this cushing ion extending the type face of the type bands beyond the surface of the fasteners 32 and 33, the intervening space 35 between said fasteners and the tires 18, to contact the paper passing over the platen 16.

When the type faces of the type bands come into contact with the distributing roll, an im edin impact occurs, and to eliminate the e ect 0% this impeding impact, we have provided the shaft 17 with counterbalances 36 suitablyxed on the shaft so as to assist the revolution ofthe printing cylinder when the ends `,of the' type bands come into contact with the distributing roll 28.

As shown in Figs. 3, 4, 6 and 7,' the side plates 7 are formed with T-shaped slots 37 having a vertical part 37a for the up-anddown movement of the shaft 17 and printing cylinder 18. y

When the working parts of the machine are in the ositions shown in Figs. 3, 5 and 7, the sh t '17 is at the lower ends of the vertical slots 37, and when in the tilted position, as shown in Fig. 6, it automatically moves to the opposite ends of said slots.

When the parts are in the position shown in Figs. 3 and 7 the printing cylinder is in 'contact with fthe paper 38 passing over the platen 16, and when the parts are in their tilted position "as shown in Fig. 6, the printing cylinder is clear ofthe paper so that the type bands can be removed and replaced without marking or printing it.

When the parts are in the position shown in Figs. 2 and 5, the fork 22 of the arm 21 is engaged with the spacing bolt 7s to hold the inking and distributing `ro1ls 27 and 28 in their normal position with relation to the printing cylinder 18 and paper 38, the principal pur ose of the forked arm being to keep the in 'ng and distributin rolls out of contact with the paper as it eeds from the paper roll 39 around the platen 16 to the paper knife 48. l

When access to the type bands on the printin cylinder is required, the parts are tilted rom the osition shown in Figs. 3

and 5 to the position shown in Fig. 6, and

when in this position, the forked arm may be moved out of engagement with the spacing blot 7*. When the forked arm is disengaged from the spacin bolt 7, it and the journal plates 19 and in ing and distributrolls 27 and 28 are moved from the position shown 4in full lines in Fig. `6 to that shown in dotted lines in the same figure, and spring catches 40 then engage the spacing bolt 7 b and hold the inking and distributing rolls in a convenient position to permit of access to them.

The arbors 39 of the paper roll 39 are journaled in the side plates 7, the side plates being provided with slots 41 for the removal and replacement of the paper roll sinned locking members 42 which bear on the arbors 39* and h -old them in their slotted bearings in the side plates 7, the locking members 42 being provided with tension `springs 43 and stops 44 to maintain them in their operative position with relation to the arbors. n

The paper 38 passes from the paper roll 39 around the platen 16 and then under a friction roll 45. T he friction roll 45 is journaled in two arms 46 pivoted interjacent their ends., as shown at 46a, to the side plates 7 and extending sutliciently beyond the front of the side plates to allow the friction roll 45 to come into contact with the paper and paper roll.

Suspended from the friction roll 45 is a bail 47, thepaper passing from the paper roll 39 around the platen 16 and between the friction roll 45 -and bail 47.

.Rotatably mounted on the friction roll 45 is the knife 48, the cutting edge of which engages the paper after it passes between the friction roll 45 and bail 47, and forming part of the knife 48 is a counterbalance 49 serving as a handle by which the knife is turned from its cutting to its inoperative position, as shown in full and dotted lines respectively in Fig. 7.

When the paper is drawn from the paper roll, it passes over the platen 16 where it is printed by the type on the printing cylinder 18, and from there, it passes between the friction roll 45 and bail 47 and under the knife 48.

The desired length of paper when Withdrawn from the paper roll 39, is torn along the edge of the knife 48 and when said length is torn ofi", the knife is tilted back into the position shown in dotted lines in Fig. 7, and when so tilted, the paper extending beyond the bail 47 is raised from contact with the paper wound on the roll, so as to be easily gripped by the user preparatory to drawing off the next desired length, the knife 48 then being turned back into the position shown in full lines in the same figure.

During the revolution of the printing cyl inder, the counter-weights 36, when above its horizontal aXis, will according to the law of gravity, seek the lowest point, and by dolng so, may cause a partial revolution of the printing cylinder. This revolution of the printing cylinder is sometimes backward and sometimes forward, and when it revolves backward, it would draw the paper from bet-Ween the friction roll 45 and the bail 47 if a tension is not provided to prevent it doing so. This tension means ive have applied to the' arms 46, and have so arranged the tensioning mechanism that the friction roll 45 maintains an uniform tension on the paper 38 regardless of any variation in the diameter of the paper roll 39.

The tensioning device consists of ltshaped levers comprising lever arms 50 pivoted at 50ate the side plates 7 and cross heads 51 bearing against the tops of the arms 46. The pivots 50a are vertically below the pivots 46 so that the lever arms 50 will rock from one side to the other of said pivots 46H.

Oscillatingly mounted on the pivots 50 are rocker arms 52 having at their upper ends, grooves 53 to receive the tongues 54 formin part of the arms 46. Connected to the roeier arms 52 and to the lever arms 50 are springs 55. Vv'hen the arms 46 are in their lowered position, as shown in Figs. 3, 5 and 7, the lever arms 50 are thrown to the front of the pivots 46, and in this position the cross heads 51 bear upon t-he arms 46 between the pivots 46a and the friction roll 45, forcing the arms downward and pressing the friction roll against the paper and paper roll, thus causing the friction roll to apply a tension to the paper roll to prevent the paper inadvertently unwinding or becoming loose in its winding. 'When the lever arms 50 are in this position, the lower ends of the arms 52 and the springs are to the front of the pivots 50, with the springs 55 draw'- ing the cross heads 51 against the arms 46. As the diameter of the paper roll 39 decreases, the friction roll 45 moves in toward the center of the paper roll andthe cross heads follow the arms 46 under t-he influence of the springs 55, thereby maintaining a tension upon the arms 46. As the arms 46 move toward the center of the paper roll 39, the cross heads approach more closely to the friction roll 45 and increase the leverage of the cross heads on the arms 46. As the friction roll approaches the center of the paper roll 39, the pins 56 to which the outer ends of the springs 55 are connected, approach the pins 56, to which the inner ends are connected. The. springs 55 durinv preach gradually contract and` diminish their tension in substantially the same ratio as the leverage of t-he arms 50 increases, to enable the friction roll 45 to maintain the same pressure on the paper roll `at its maXimum and minimum diameters.

When the arms 46 are raised int-o the position shown in Fig. 4, they throw the lever arms 50 to the rear of the pivots 46, and in this position, the cross heads 51 engage the arms 46 in rear of the pivots 46e. As the arms 46 rise to the position shown in Fig. 4, the tongues 54 engaging. in the grooves 53 rock the arms 52 so that the lower ends of said arms and the springs 55 will be in rear of the pivots 50a, to maintain a downward 'pull on the cross heads 51, and enable them to apply the necessary pressure on the free ends ,of 'the arms 46 to hold the arms 46 in their'v elevated position, the upward movementJ of the are-'s 46 being limited by the nuts 57 on the spacing bolts 7*".

such ap- To retard the revolution of the paper roll 39, we have provided a tension roll 58, the arbors 58a of which are mounted in inclined slots 59 descending in the direction of the arbors of the paper roll 39.

At the ends of the slots 59 remote from the paper roll 39 are angular slots 60, the purpose of which is to receive the arbors 58a and hold the tension roll 58 in an inoperative position when a new roll of paper is being placed in the machine.'

lVhen the paper roll is placed in the machine, thearbors are raised out of the L- shaped slots GO and the tension roll 58 descends along the inclined slots 5S) until it comes into contact with the paper roll 39 with which it remains continually in contact.

To make the contact of the tension roll with the paper roll positive, we have pivoted to the side plates 7. two arms 61 tensioned by springs62 which bear against the arbors 58a and force the tension roll into contact with the paper roll and maintain it in contact therewith.

From t-he foregoing description it will bea understood that the main frame when moving to and from the working position of the apparatus carries with it all of the essential parts of the machine without disturbing their working relation, so that when the parts are restored to their working position they will automatically resume the performance of the functions for which they are intended.
