24 claims. (ci. :a1-14.5)

yThis invention relates to an improvement in machines for sealing packages, parcels or the like, and more particularly to a machine which, when actuated, will moisten and feed out a strip of gummed paper in condition to be easily applied to a package or the like.

It is one of the objects of the present invention to provide a power actuated machine of this type, which, when the actuating lever is operated will automatically feed outthe moistened strip of paper.

Another object of the invention is to provide a machine which will moisten and feed out the strip of paper gummed side up in position for a package to be placed thereon for sealing.

Another object of the invention is to provide a machine which will operate to moisten and feed out the gummed strip as long as the operating control means therefor is held in operating position and which will automatically stop the feeding of the strip and cut of! the portion fed out when the control means is released. A

The invention also contemplates various improvements` in the details of construction of a machine of this type as will appear more clearlyv hereafter.

Referring now to the drawings which illustrate a preferred form of embodiment of the invention.

Figure is a view of a modiiied form of moistening device for use when the strip is served gummed side down.

In the embodiment illustrated'in Figure 1, the machine is shown in operative positionfor quickly wrapping the gummed strip 8 around a package A and sealing the same. 'I'he strip feeding machine 1 is supported by a table or counter 2, and comprises a holder 3 for the roll of gummed paper 4, a power driven strip feeding device 5, a foot lever 6 for controlling the operation of the strip feeding device, a moistener 7 for moistening the top of the gummed strip 8 as it is fed from the machine and a knife 9 between the feeding mech- 1 anism and the moistener for cutting ofi the fed strip when the foot lever 6 is released A block 10 is providedand the package Ais placed thereon after the moistened strip 8,

gummed side up has been fed out over the block.

A scale 11 inthe runway trough 12 assists the operator in estimating the correct amount of strip necessary to wrap any particular package.

With the strip inthe position illustrated and the package in place thereon one of the operatorshands may be passed thru the space B between the end of the strip feeding machine and the block 10 and the other hand may be inserted below the end of the strip in the trough 12 and the ends of the strip folded up along the sides and over the top of the package A to seal the same. In the sealing operation the vmoistened strip is rubbed against the sides and top of the package to insure a rm contact therewith and the bottom .of the package may be rubbed overthe block 10 to assure rm contact at the bottom and when the 4package is placed in the chute ortrough '12 and slides down to the discharge end thereof, the friction of the trough against the bottom of the packages also rubs the sealing strip into firm contact therewith. v

Referring now to the preferred construction of the strip feeding machine, as shown in Figures 2, 3 and 4, this comprises a pair of side frames 15 held-in spacedfrelation by the cross members 16. At one end a plurality of rollers 17 are provided'` between the side frames 15, upon which the roll 4-of gummed paper is supported.v Side lugs 18 projecting inward from the frames 15 keep the roll 4 in .the center of the machine.

From the roll 4 the strip of gummed paper 8 passes upward over the smoothing iron 19, above which a presser 20 is located. The presser 20 comprises a right angle lower member 21 provided with a roller 22 and a pad of felt or the like 23,

and an upper weighted membe1 24 an`d is pivoted at 25 so that thefweight 26 forces it down over the iron 19 to take the curl out of the paper as it passes Athereover and exerts a' limited 'resistanc'e to the withdrawal of the strip .from the roll.

The vstrip feeding mechanism comprises'alowrotatable in the side frames 15 and an upper movable feeding roll 29 carried by the stud shaft 30. rIhese rollers are constantly rotated by a gear 31 on the shaft 32, which is driven thru the reducing gear 33 from the pinion 34 of a constantly running electric motor 35. The gears 36 and36a on the

shafts

28 and 30 are provided with very deep teeth so that the

rollers

27 and 29 may be moved apart a limited distance thru the raising of the stud shaft without moving the gears out of mesh.

The stud shaft 30 is supported in a wide bearing 37 on the yoke member 38 which is pivoted at 39 to a rod 39a extending between the machine frame members 15. A coil spring 40 acts upon the yoke member 38 to hold the roll 29 normally spaced above the strip 8 as shown in Figures 5 so that no feeding occurs.

An extension 38a on the yoke 38 is connected thru the adjustable rod 41 to the lever 42, adapt- -ed to be actuated from the foot lever 6 in a manner to be described, to pull the yoke downward and bring the

moving rollers

27 and 29 into contact with the strip to feed the same thru the machine. A stop 43 prevents the spring 40 from raising the yoke 38 so high as to move the gears 36 and 36a out of mesh. f

From a point adjacent the

rollers

27 and 29 the gummed strip 8 passes thru a guide member 44, comprising a lower member 45 which begins adjacent the smoothing iron 19 and iscut out at 46 for the roller 27 to extend therethru and a removable uppermember 47 removably secured by the screw clamp 48-49 to the cross block 50 so that by loosening the screw 48 and sliding the upper member -47 rearwardly until the end 47a is out from under the block 50, the upper member may be removed for inspection and cleaning of the machine.

A knife 9 is pivoted at 52 to adjacent one end of the block 50 and is adapted to be moved downwardV out of the path of the strip when the strip is being fed forward by the

rollers

27 and 29. To effect this movement, the knife 9 is connected by an adjustable link 53 to a lever 54 pivoted at 55 on the machine frame. The other end of the lever 54 is connected by means of a link 56 to the foot lever 6 so that when the foot lever is depressed the knife is drawn down. When the foot lever is released the spring 57 pulls up the lever 54 and projects the knife across the strip-to cutoff the portion fed out of the machine, an adjustable set screw 51 in the machine frame serves as a .stop to prevent the lever 54l and knife 9 from being raised too high. l' The depressing of the foot lever 6 draws the lever 54 into contact with the lever 42 to pull *Y down the yoke member 38 and bring the rotating feed'roller 29 against the surface of the strip 8 so that the rotation of the

rollers

29 and 27 on the top and bottom faces of the strip feed it forward thru the machine. The position of the lever 42 is below the lever 54 so that when the foot lever 6 is depressed the knife 9 is withdrawn from the path of the strip before the feed roller 29 is brought down to feed the strip forward, and when the foot lever is released the spring 40 elevates the yoke 38 and lever 42 to stop the feeding of the strip before the knife 9 is projected across the path ofthe stripto sever the end which has been fed out of the machine.

Beyond the knife 9, the strip 8 passes thru a guide way 57 and under the' brush 58 of the moistening device 7 by which the upper gummed surface of the strip is moistened. The mOistener for moistening the strip with the gummed side up comprises a tank 59 for water or the like, a wick 60 comprising a plurality of layers 61 which extend over the brush 58 and project down within the water in the tank 59 so that the water rises by capillary attraction in the wick and flows down to the end of the brush.

Y The brush is supported in inclined position by the supports 62 having slots 63 in which the brush support 64 on the rod 64a may be adjusted to preserve proper contact between the end of the brush and the strip 8 and the top of the tank acts as a support for the underside of the strip. A shield 65 covers part of the Wick and the top of the brush to hold the wick in position.

As illustrated in Figures 7 and 8 the layers 6l of the wick are preferably composed of cotton batting or the like 66 covered with cheese cloth 68 or similar material which may be sewed with loose cross stitches 67 to keep the cotton in place in the wick. v

Figure l0 shows a modified form of moistening device for use when it is desired to feed the strip 8 from the machine with the gummed side down. This comprises a tank 70 for water or the like having a brush 71 extending out thru an opening 72 in the top of the tank and a presser plate 73 pivoted at 74 on the tank forv pressing the strip 8 into contact with the brush.

The knife 9, lever 54, etc., in this modification operate just as in the forms of embodiment of the invention previously described. To feed the strip out gum side down, the roll 4 is merely reversed, so that the gummed side of the strip 8 is underneath.

Various modifications and changes may be made in the embodiment of the invention shown and parts thereof may be used without the whole without departing from the spirit of the invention or the scope of the4 appended claims.
