HOLDING AND PRINTING MECHANISM FOR WRAPP NG PAPER AND oTHER RoLLs.

Application filed November 3, 1925, Serial No. 66,452, and in Australia August 15, 1-925.

This invention relates to mechanism whereby the web of a roll of sheet material, such as wrapping paper used in shops, will be printed upon as it is being withdrawn 5 from the roll. Advertisements and/or other notifications may thus be put on the wrappers before the latter are made to enclose goods.

Our improvements relate to the machine frame and .to the inking and printing mecha-,

nisms. The frame'carries all the parts conveniently, each of various rollers of this machine being easily changeable for another. The ink will not leak from its reservoir, and

frequent renewal of ink will not be required.

- The colour or colours of ink can be varied.

Our machine will operate as a counter. adjunct, and allow of easily drawing out the paper and tearing it off, leaving an edge of paper ready for grasping when the next withdrawal occurs. 'Any desired length of. paper may be drawn from a roll in contact with the printing roller or rollers, before I severing. The severing need not be for wrapping purposes; as paper is, when printed'on suitably, often of use to make a win-. dow frieze,- or background, or for other purposes. I a

Construction according to this invention is herewith illustrated, but details may be modified while retaining any combination hereinafter claimed.

In the drawings, Figure 1 is a tional view of the machine.

Figure 2- is a front view partly in section of the machine equipped with two rolls of paper, and with an inking and printing device for each roll.

Figure 3 is a side sectional view of part 40 of Figure 1, but set in a different position, which will permit of removal of the print-. ing roller, or if desired the said roller and parts under it. I

Figure 4 is a perspective view of part of 4 the inking mechanism.

The machine has a main frame formed by cheeks 1, 1*, connected and spaced apart by bars of'which three, 2, 2",2 are shown,

either cheek being removable, by unscrewing the end fastenings which are shown as nuts 2 on the said bars. This frame has feet which are adapted to rest and stand firmly on glass or other polished surfaces,

side secagainst a cheek.

and also adapted to allow the machine to be slid into'other positions withoutdamaging the glass or other supporting surface..- Thus on the underslde'of each foot is a pad 1, which may be of rubber.

At an upper front part of the machine, that is facing the operator each cheek has a bearing, the entrance to which is aslot'l, I

Figure 1, carrying the end of a removable spindle 3, herein called. the main" spindle,

which carries the paper roll or rolls.

We show two rolls 4, 4?, and to align these with their printing 'mechanismswe provide shdable means of-suitable form, shown as members 5 and 6. Thus. the member 5 has apertures throughwhich extend the spindle 3, and the bars 2', 2, 2 Through the member 6' which is small, only the spindle3extends. Member. 5' and member 6- will be each set abutting against a roll of paper, as

in Figure 2, to prevent the latter sliding out,

of printing alignment; but members 5, 6,

may if desired be. set at either side of the side abutting main frame,'or on'e at each When only .one vp aper'roll in use, but

needs. to be prevented from sliding, one alignment member will suflice, either. a plate 5 or a member-6. The.plate-5 is shown abutting against the tone, and the member removed or not. Plate. 5 has a perforated V lug 5 carrying a set screw 5 extending 6 against .the'roll 4, keeping these paper rolls in alignmentwiththeir' printing roll- Plate 5 has thefurther advantage that, when a cheek is removed it will retainthe through the perforation togrip the spindle;

member 6 has also adjustment means shown as a p1n3 lnserted m a vhole 1n the .SPlIlCllB, which has sufficlent holes for selection pur' poses.

. We provide at the frame rear a trough or troughs 8, two being shownin Figure 2. These are slidably supported 'onthe bars 2,

2 which .are parallel. This trough has at its lower part means, shown as eyes 8*, engaging the bar 2, and has at its upper part means, shown as-a clip 8? which frictionally grips the upper bar 2*,but is detachable therefrom by hand pressure, .Ontl'etaching the clip as in Figure 3, the trough top will swing rearward, and thus permit an attendant to have easy access to the trough contents. e find it to be convenient to make the trough with cast metal ends 8, each carrying an aforesaid 'eyc"8' ,"the walls and'base of the trough being ""of' s'heet"'1 ne'tal secured to "the ends, the front wall being provided with the said clip 8" which may be integral.

The trough base is its ink-containing part, and meansare provided to limit the amount of ink therein. Thus a passage 9 having an escape'opening e r-is shown at a suitable level- Thisiopening and passage (the taper the-latter"beingshown wide) are usable for 1 replenishing the ink. 9 'indicatesra" closing Above the ink well at the trough base, the trough conta'i-ns 'in'k distributing. means. Withinlthe trough and" at each'end thereof is agui'de formed, forfiexample, by a channel bet\veen-"two =ribs '10.

' Above the or each printing" roller is an abutment roller 1.7 which is in one'picce or is formed in sections, so that any sectioir can be independently rotated: This roller has a spindle 17 supported in bearings 17? in cheeks 1, 1

As the mechanism which is located below the abutment" roller is subject to the'upward. pressure of the springs'12 and14, thesaid mechanism rises as high as :the abutment roller allows; and as the paper from'the;

source provided as the roll is made-to pass between the abutment roller and the print ing roller, the paper willitherefore become printed onby' the contacting roller? as the paper'is moved along.

In practice the paper is drawn out, as shown in Figure" 1 by broken lines, from the roll and is'passedv under-the abutment roller, then above the latter, and then to a guide which is provided, shown 'as a 'roller' 18, over which the paper isdrawn pastfihe edge of ablade 19,'termed the tearing-blade. This blade is-supportedat the frontofthe' top frame which has suitable pivotal -supports such as the bearingso'f-the abutment roller 17;. This top frame can" be easily grasped by being swung upward, as per the,

arrow in" Figure 1; This "top frame""con'- sists of the parts 18, 19, and 20. It'eXtends' above,- and is supported iat'its front by the You of P p n mally; but whenraised by swinging'it as per arrow A, it'ismoved clear of the paper roll which" can then be changed. 'This top frame carries paper retaining clips 21 above guide roller-18,' to press on: the paperand keep it in aligrr ment, the clips holding the paper "against 120 the said roller.

As'the roller 18, which rests on the paper roll, is easily rotatable by'f1TlCtlOI1,jl3h61l11- rolling of the papeifrequired from time to time will not be materially impeded; '"A tearing blade'19 of any suitable detail, as,

contact rotate when an attendant grasps and i pulls the paper by seizing its edge 4; that is the printing roller 7 will rotate, and will receive ink from transfer roller 16 or the like, which will rotate.
