TAPE-FEEDING Application led March 27, 1924. Serial No. 702,421.
To all whom t may concern:
Be it known that I, CHARLES G. MOR- TIMER, a citizen of the United States, and a resident of Glen Ridge, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Tape- Feeding Machines, of which the following is y a specification.
rlhis invention relates to an improved tape feeding and moistening device which operates so that gummed tape usually made of stif paper and which is used for sealing packages and parcels is projected from the machine and cut ofi at the desired length. f
'lhe particular machine embodied in this invention is one that is easily operated and has also the advantage of maintaining its parts in alignment and in proper working order throughout long and continuous operation, the structure being such that the parts are compactly arranged and in which gears and a rack for actuating the feeding and moistening rolls are constantly in mesh.
rlhe invention is also designed to provide a machine of this kind in which there can be a quick and convenient adjustment to provide for either short or long lengths of tape delivered during one operationof the handle.
rlhe invention is illustrated in the accompanying drawings in which Figure 1 is a vertical section taken on line 1 1 in Figure 3. Fie 2 is a side view of the machine. Figure 3 is a front view of the machine with the cover shown in section and with the front plate'of the tank removed. Figure d is a side view of the front partof the machine, this view being similar to Figure 2 except that the shield carrying the adjusting mechanism is removed. Figure 5 is a view of the other side of the machine with the shield on that side partly broken away. Figure d is a section taken `on line 6--6 in Figure 1. Figure 7 is a section taken on e 7--7 in Figure 2. Figure 8 is a sectional detail of one of the clutches in the machine.
The machine consists of a frame which is provided at the hack with a well or other suitahle means for holdin the roll of tape 10. The frame is usual y made of side pieces 11 between which is supported the hottom 12 of the well 13 although other means of securing the roll of tape can be used.
the feed roll 14 and the feed roll 15 above it these being pressed together by the spring A'PA'lEN'r OFFICE. l
16 in each side bearing 17 of the roll 15.
These rolls operate in unison by, reason of the meshed gears 18 and 19 connecting the shafts of the rolls, the roll 14 being secured to the shaft 2O which projects at one side ofthe machine and is operated from a gear o 21, and a suitable clutch mechanism which is shown in detail in Figure 8.
The gear 21 is in the nature of a hub on the shell 22 which surrounds the arms 23 secured on the end of the shaft 20. The face 24 of each arm is tangential to the centre of the 4shaft and the rollers 25 are thus caused to hind `when the shell 22 is rotated in one direction and thus vcarries the shaft 20 with it but when moved in the opposite direction the rollers retreat and there is no transmission of movement from the gear to the shaft.
In front of the feed rollers and spaced therefrom are moistening vrollers one of which is the roller 26 which does vthe actual moistening since it rotates with part of its surface in water in the tank 27. The other roller 28 simply presses by its own weight on the roller 26, since its bearings ride freely in the slots 29 in the upper part of the side plates 11 of the frame.
The roller 26 is mounted on the shaft 30l which is equippedwith a gear 31 on the shell 32 similar to the shell 22 of the feeding roll 14 so that the moistening roll also operates with the gear only in one direction and is released therefrom when moved in the other direction. The gears 21 and 31 are in mesh with the rack 3ftwhich includes a plate 33 having the pivotal holt 35 which passes through the frame of the machine and is fastened hy such means as acotter pin 36 .on the opposite side.
The rack 34a is arc-shaped and being arcuate with the bolt 35 as a centre. The gears 21 and 31 are disposed so that they are in the path of travel of the rack 34e and are always in mesh with it. The rack is yieldingly held in normal position by a spring 37 and is stopped on its backward movement by the stop' 38 -which is usually covered with rubber so as to deaden the noise.
The rack has a handle 39 which when pushed down swings the rack on its centre the rack. This stop consists of a shield 40 1 which also acts as a cover for the curved rack and its associated parts and it has a swinging plate 41 underneath which Swlngs Vacross an opening or slot 42, one edge of which has the teeth 43.
The latch 44 is adapted to engage any one of these teeth, being mounted on the pivot 45 and having the spring 46 to press it nor- 4mally in. engagement with the teeth 43. On
the inner face of this plate which forms really part of the wall of the shield, is the stop 47 so that as the latch 44 which projects through lthe slot 42 and forms a'finger piece, is adjusted it carries with it of course,
-the stud 47 which is in the path of the stud 48 (see Figure 4) which when it is brought forward by the operation of the handle 39 engages the sto 47. Therefore it will be evident that if t e rack 34* is only permitted to move a short distance ashort length of l tape will be fed forward or if allowedl to travel all or nearly all of its limit of move-` ment it will feed a longer length of tape.
When the handle is released and slips back into position, the clutches of course, prevent the feed and moistening rolls from moving backward but this return movement cuts the tape oil' between the feeding and the moistening rolls.
In the form shown I show a fixed blade 49 which is fastened across the machine to the side plates thereof as will be seen from Figure 6 and the movable blade50 cooperates therewith to shear olf the paper, the blade 50 being pivoted as at 51 and having on its free end the stout wire or similar connection 52 secured to the end of the bell crank 53 which is normally pressed upward 'by the spring 54.
The tooth 55 is loose on itspivot and when the linger 56 and the plate 33 swing forward it lifts this tooth 55 and the knife is not disturbed. On the return movement however, the tooth 55 abuts against a rojection or stud 57 on the short arm of the Iliellcrank 53 which pulls down on the wire 52 and causes the blade 50 to be sharply brought down to shear olf the tape.
The lingers 56 and the tooth 55 are close together so that even ifa short length ofI tape -is fed forward the parts are in position for cutting olf the tape on the return movement.. The parts are so disposed that when the cutting is completed the finger 56 rides of'theend'of the tooth 55. l,
The tank. 27 is removable so that it can be easily refilled or cleaned,`l1aving at its rear end the socket 58 which has at the front an upwardly extended splash plate 59 to mslm/3,183.
prevent water from being splashed up against the tape before it is cut andis supported at its front end by the front plate 60 supported on one or more feet 61 which A yas a guard or bearing for the knife when it is moving upward, these plates being secured to a cover 68 pivoted at the back at 69 so that when the cover is raised these plates go with it and there is ready access to the cutting device and the feeding and moistening mechanism and new tape can be easily stared through the machine whenthe cover 1s o I arrange a loose roller 70 which rides freely between the plate 59 and the moistening roll 26 and acts to shed excess water from the moistening roll so that nothing except the thin film necessary to thoroughly wet the gummed side of the tape, is carried over by the roller.
In operating the machine after proper adjustment for the length of tape desired has been made, the handle is pressed down which through the rack, the gears, and the the required amount of tape when th'e fingers release the handle and the handle snaps back and as it approaches the end of its return ,clutches operates ,all the rolls and they feed.v
movement it has suliicient momentum to 'started there is no lost motion and the-feed-I aper is initiated as soon as the ing of the handle of t e rack is pressed down.
