PATENT oFFlcE FRANK HABTIAN, F KENSINGTON, -LONDON, ENGLAND rnm'rme ArrLuNcn Application led September 3, 1927, Serial lo. 217,482, and in Great Britain September 18, 1926.

This invention relates to printing and like appliances applicable to web delivery apparatus. Whilst the apparatus is more especially applicable to web delivery apparatus ,5 in'general the invention is more particularly applicable to apparatus for delivering gummed strips. The object. of the present invention is to provide a simple and compact appliance by means of which advertisements, notices and so forth may be applied to a roll tated so that an impression will be produced on the paper or the like. The roll of paper or the like is preferably so supported that whilst it is being unrolled it bears with sub-- stantially uniform pressure upon the printing roller or rollers. The pressure may either be produced by gravity, by springs or equivalent means, and the arrangement may be such that either the roll is pressed against the printing roller or rollers, or the printing roller or rollers are pressed against the roll of paper or the like. When the printing appliance is combined with a frame for supporting gummed paper the appliance is provided with a device for moistening the gummed surface of the paper after an impression has been made on the paper. Beyond the moistening means there is provided a cutter or like device so as to facilitate the tearing olf of the moistened strip. When the strip is torn olf there is usually a tendency for the paper or the like to roll up thus drawing the paper backwardly. This is liable to cause blurring or smudging of the impression and in order Y to avoid this difficulty there is provided a device for engaging the paper at a point substantially opposite the end of the moistening device. This engaging device preferably.l

consist of one or more sharp pointed projections or pins which are adapted to pierce the paper and engage therewith. The engaging devlce thus also serves to hold the paper or the like away from the moistening device whilst the apparatus is not in operation. One or more ink ducts for supplying the inking rollers and also the moistening device may be either permanently mounted in the frame of the appliance or may be made separate therefrom and adjustable therein.

The printing surface on the printing roller may be in the form of a rubber 'pad wound round the roller or may be in the form of interchangeable type or plates.

The invention will now be described by way of example, in connection with apparatus for printing upon a roll of gummed paper as shown in the accompanying drawings where- H12- Fig. 1 showsa side elevation of the appa- -ratus Fig. 2 shows a plan view, the supporting arms, roll of paper, the device for engaging the paper, and the cutter or the like being omitted, and

Fig. 3 shows a detail.

In the construction 'illustrated a printing roller 1, is mounted in bearings 2, on a base 3, and an inking roller 4, bears against the surface thereof. A single inking roller 4 is preferably used when the type or the like on the printing roller 1 is only to be inked with one colour, but if separate rows of type are to be inked with different colours then a separate inking roller is provided for each colour, or a single inking roller suitably subdivided, is

Y used. The inking roller 4 is mounted in bearings 7 provided on the container 5.

The inking roller 4 is supplied with ink from an ink duct preferably consistincI of a container', which is completely closed with the exception of a hole for the passage of a wick 6. This container 5 is adapted to be adjustably fitted into the 'frame 3 of the machine, so as to enable the inking roller 4 to'be brought into correct relation with the printing roller 1. The adjustment is effected by means of set screws 8, passing through spring plates 9 and springs 8', but may also be effected by means of set screws passing through elongated slots in anges provided on'the container 5 and screwing into the frame of the ap pliance.

The wick 6 which conveys the ink from the container 5 to the inking roller 4 may pass either directly into the container 5 or may be fitted into -a tube or sleeve adapted .to be iittcd into the container 5.

When diii'erent coloured inks are to be used separate ink containers 5 are provided for each different-ly coloured ink or the container 5 is divided into separate compartments each of which is provided with its separate wick and if desired with a tube or sleeve For the purpose of moistening the gummed paper a water container 10, of substantially the same construction as the ink container 5,

is provided. This container 10 is also adjustably mounted in the frame, preferably in the same manner as the ink container 5.

The wick 11 of the water container 10 serves to apply moisture to the gummed sur-` face of the paper.

Substantially opposite the moistening wick 11 there is provided on the frame 3 a sharp pointed projection, pin or the like 12 which is adapted to engage ywith the paper A as this vis severed by being drawn across a cutter 13,

perforator or other suitable device for facilitating the tearing oli' of the gummed strip. By its engagement with the paper or the like this projection or pin 12 also serves to hold the paper away from the moistening wick 11 when the apparatus is not in use and as a short distance separates the projection 12 from the cutter or the like 13 there will always be a suiiicient amount of paper beyond the pin 12, as indicated at 14, which can be gripped by the lingers in order to draw a further length of paper through the apparatus..

In the frame 3 are pivotally mounted two arms 15 which are adapted to support between them a shaft 16 on which the roll of paper A or the like is mounted. This roll is adapted to bear on the printing roller or rollers 1 so as to be printed upon as it is drawn out of the machine. In order that various widths of paper may be accommodated the arms 15 are provided with bosses adapted to,

` which is pivotally mounted in the frame.

This shaft 18 is preferably provided at its ends with projecting pins 19 adapted to engage with recesses in a pair of screw members 2O engaging with the frame 3 and form ing the bearings for the shaft 18. It will however be understood that the pins 19 may be formed on the screws 20 and the recesses in the shaft 18. The shaft 16 is provided with annular grooves 21 formed by collars 21L arranged at different positions according to the width of paper which is to be printed upon. Adjacent the printing roller 1 there are mounted in the frame 3, a pair of guide arms x22 which extend over the printing roller 1 and are capable of adjustment on a shaft 24, by means of set screws 23 so as to be set in a position according to the width of the paper or the like in order to guide this over the printing roller 1. The shaft 24 is preferably provided at its ends with milled heads 25, so as to enable it to be turned in order to lift the arms 22 for placing the roll of .paper in position. In order to facilitate threading the roll of paper or the like on the shaft 16 one of the arms 15 is preferably provided with a slot 26 so that it can be conveniently disengaged in order to permit of the roll of paper A or the like being readily threaded on the shaft 16. This slot is preferably provided on the underside of the arm. ln order to mount a roll of paper A on the shaft 16, the arm 15 provided with the slot 26, is swung upwardly on the shaft 18 and the roll of paper isplaced on the shaft 16 with one side against the arm 15 in which the shaft 16 is mounted. The slotted arm is now lowered and the slot 26 therein is brought into engagement with one of the grooves 21 according to the width of the paper roll and thus serves to hold the` paper roll A in proper position on the shaft 16.

Between the printing mechanism and the moistening device is arranged a guide roller 2( and this is so arranged thatthe roll of paper bearing on the printing mechanism has the free end passing around the guide j and consequently the weight thereof is reduced the pressure by which the paper bears upon the printing roller will be substantially uniform throughout.
