MACHINE FOR FASTENING TOGETHER FOLDED SHEETS OF PAPER WITH ADHESIVE MATERIAL Filed Aug. 31, 1932 Patented Aug. 8, 1933 UNITED STATES PATENT OFFICE FOLDED SHEETS HE SIVE MATERIAL OF PAPER WITH Alexander Parker and Geoffrey Parsons, Auckland, New Zealand Application August 31, 1932, Serial No. 631,240, and in New Zealand August 22, 1931 11 Claims.
This invention relates to machines for issuing gummed strips of paper or other suitable material capable of being used to secure together a plurality of thicknesses of paper either in packet or missive form for mailing or otherwise, or in book form, or merely superimposed.
The object of the invention is to provide for the aforesaid purpose an improved form of machine capable of issuing gummed strips of material, damping the gummed surfaces thereof, and applying said strips to bind thicknesses of paper securely together at a desired point. Printed matter can also be placed on said strips so as to be exposed to view when the latter are in position on the packet, missive, book, or the like.
According to the invention, the improved machine comprises a base having mounted thereon a roll of gummed paper or the like, a feed roller over which said paper or the like is passed, a damping wick for contacting with the gummed surface of the latter, a lever carryinga paper or the like cutting knife, means on the lever for gripping a packet, missive, or the like comprising thicknesses of paper to be secured together, feed roller actuating means operated from said lever, and a pair of spring pressed rollers, between the members of which the packet, missive, or the like and a severed section of dampened gummed paper or the like are passed in order to apply the latter to the former.
The invention is illustrated in the accompanying drawing and will be further described in conjunction therewith,
Fig. 1 being a side elevation of the machine with the cover shown broken away,
Fig. 2 a front view thereof, with the cover removed,
Fig. 3 a part longitudinal sectional view taken through the forward portion of the machine,
Fig. 4 a cross sectional elevation through line A--A Fig. 3, with the water tank removed, and
Fig. 5 an edge view of a packet or missive showing the thicknesses of paper comprised therein secured together by a section ofgummed paper or the like.
Referring to the drawing, 1 is the base from which rise brackets 2 to support a feed roller 3 and brackets 4 to support the side members forming a lever 5, while between the side members of said lever are spring brackets 6 also rising from the base 1 to support a roll of gummed paper 13 or other suitable material to be used in securing together the thicknesses of the packet, missive or the like, indicated at 7 in the drawing.
Also on the base 1 is a water tank 8 supported by legs 8 and shaped for accommodation partly over the feed roller 3, said tank 8 being provided with a filling inlet 9 and stopper 9 and containing a wick 10 which passes over a tray 11 hinged to the tank 8, said wick 10 passing below a cross pin 10 in the tray 11 and emerging through a slot 12 in the forward end of the tray 11, and over a platform 11 over which the paper 13 travels.
The feed roller 3 has spikes 3 on its periphery and the gummed paper 13 is led from the roll thereof below a guide roller 14 on the base 1 and up around the feed roller 3 between the latter and a spring press 15 attached to the tank 8, and then over a pair of rollers 18, the supports 16 7 for which from the base 1 are of spring metal fastened together by screws 17 so as to cause the rollers 18 to press firmly against each other.
The spring brackets 6 for the roll of gummed paper 13 can also be clamped together by'means 7 of nuts 6 placed on the spindle of the roll, to a degree sufiicient to prevent over-running of the roll.
The spring press 15 ensures the paper 13 being engaged on the spikes 3 of the feed roller 3, so 0 that when the latter is given turning movement in the direction indicated by the arrow (Fig. 3) the paper 13 will travel with it.
The lever 5 before referred to is normally maintained with its forward end raised, and its 5 rear end bearing against stops 4 on the brackets 4, under the action of springs 19 in tension between the rear end of said lever and the base 1.
The forward ends of the side members of the lever 5 are connected together by a cross bar 20, 90. to which is attached a face plate 21 having a portion removed at 22 and ledges 23 at its lower edge one at each side of the gap left at 22.
At the back of the cross bar 20 there is attached a knife 24 the cutting edge of which is destined to pass just in advance of the platform 11 when the front end of the lever 5 is lowered or forced downwards, the front end of said platform 11 providing a shearing edge for the knife 24.
Curved arms 25 depending from the forward end of the lever 5 one at each side thereof, have mounted between them in front of the face plate 21, a rod 26 on which is mounted a forked lever 27 provided with a handle 28 and feet 29, the latter normally contacting with the face plate 21, above the ledges 23 thereon and one at each side of the gap 22. I
The end of the Wick 10 which emerges through the slot 12 in the tray 11 is normally held raised above and clear of the paper 13 by the ends of a bar 30 on the forward end of said tray, being engaged by the inturned ends 31 of arms 31 depending from the forward end of the lever 5 one at each side thereof.
In order to impart turning movement to the feed roller 3 in the direction indicated, there is provided on one side of the latter, aseries of spaced pins 32 arranged in a circular path around the centre of said roller, one of said pins 32 being engaged by a spring pressed hook pawl 33 depending from the lever 5, during upward movement of the forward end thereof, while a check pawl 34 also spring actuated, is mounted on one of the brackets 2 to engage a pin 32 and hold the roller 3 against the movement when the pawl 33 is inoperative.
Briefly, the operation of the machine as follows:
The paper 13 is passed with the gummed surface upwards, through the machine as described.
,A packet or missive, or a plurality of ,thicknesses of paper otherwise formed, is inserted as at '7 with the edges to be bound or secured together, downwards on .the ledges 23 of the face plate 21 and between the feet 29 of the lever 27 and the face plate 21.
The operator then applies downward pressure to the handle 28 which causes the packet, missive, or the like '7 to be firmly gripped between the feet 29 of the lever 27 and the face plate .21.
Continuing the downward pressure-on the lever 27, the forward end of the lever 5 is forced downwards, and allows the end of the wick to rest on the paper 13 on the platform. 11, following which the knife 24 descends and acting in conjunction with the front edge of said platform 11*- severs a section of gummed paper 13 from the strip thereof, said severed portion being located over the rollers 18 and directly below the lower edge of the packet, missive or the like 7.
Continuing still further the downward movement of the forward end of the lever 5, the gap at 22 in the face plate 21 passes upon the rollers 18, between which the lower edge of the packet, missive or the like 7 is passed causing thesevered portion of the gummed paper 13 to be doubled by said lower edge and to be pressed by the spring pressed roller 18 firmly against each side of the packet, missive, or the like.
Upon the handle 28 being relieved of downward pressure it is immediately returned upwards by the springs 19, and in moving upwards the pawl 33 engages a pin 32 and imparts turning movement to the roller 3 to feed the gummed paper again over the rollers 18 in readiness for the next operation of the machine, but prior to said feeding operation of the roller 3, the projection 33 on the pawl 33 disengages the check pawl 34 from the pin 32 with which it is engaged so as to allow' the roller 3 to turn.
As the portion of the paper 13 located over the rollers '18 may be moistened some time prior to its cutting and doubling on the packet, missive or the like, and may therefore be dry when the machine is used, as for instance if the machine has been left standing for some time, it will be necessary on some occasions to discard the first section of severed paper, by operating the machine once, before inserting the packet, missive or the like.
Water is maintained at the desired level in the tank 8, the wick 10, by the law of capillary attraction, providing the medium for passing the water to the gummed surface of the paper 13 with which it comes in contact.
A roller 35 carrying type and provided with an inking roller 35 can be mounted in the base 1 and a coacting roller 36 can be provided above the latter, for the purpose of applying printed matter to the ungummed side of the paper 13 prior to the latter passing to the feed roller 3.
