This invention relates to paperservingmachines and more especially to machines for serving gummed paper. strip in condition to be immediately applied to a package or the like. One of the objects of the invention is to provide a machine of the type having an inclined tape guide which considerably facilitates and cases the work of the operator, reduces the overall length of the machine and secures other advantages. 7

Another object of this invention is to pro-. vide a means for serving paper strip with its gummed surface properly moistened, in any desired length or lengths and to accomplish this service without spreading the moistening and material beyond the desiredconfines for the same.

It is also an object of this invention to providea serving device from which 'complicated mechanism has been eliminated with a resultant increase in the convenience and simplicity of its use, to provide a device of such size and shape as to capable of most convenient location and of use without involving the inconvenientfand unnatural movements on the part of its operator invention to pro necessary with previous devices.

More especially. it the purpose of this 'fde a machine capable of serving paper strip: of widths, and in lengths, not conveniently handled in the device described in my co-pending application Serial No. 661,168, filed September 6,1923, and to effect certain improvements in the mechanism and arrangement of that device as will be hereinafter described.

Another object of the invention is to provide" a mach ne which" will automatically serve a measured length of strip, and in which the length can be readily increased or decreased a measured amount by manual operation of the serving mechanism. In the accompanying drawings which illustrate preferred forms of embodiment of the invention, like parts have been indicated by like numerals throughout'the several views:

In the embodiment of the invention illustrated in Figure 1, the machine comprises a pair of substantially triangular side frame members 20 connected by cross members 21 and spaced apart a. sufiicient distance to receive the tape serving mechanism therebetween. l p

This tape serving mechanism comprises, a roll supporting pan 12, supported from the cross members 21, which v,is'provided with an inclined bottom 12 which tends by gravity to keep the roll 10 which may beinserted by merely pushing same in at the rear between the members 20 in proper p0- sition in the pan. The roll 10 when in position in the pan contacts at one point with the bottom of the pan and at another point with the back of the pan or with one of the cross members 21 so as to prevent the unwinding of the strip 11 except when the strip is being withdrawn from theroll in the manner designed. The roll 10 of gummed paper strip extends in a strip 11 its lengh as is illustrated in Figure 5 to allow egripper 50 to extend through the slot and engage the paper strip. A 'short portion at each end of the bottom guide member is unslotted and the rear unslotted end is bent, into the paper strip receiving apron 32 which is bent around the cross .The strip feeder 40 is shown particularly" in Figures 3 and 4 and comprises a slider base 41 formed preferably from sheet metal, which passes. under the guide 30 and extends up over the edges of the guide to-form ears 42 which loosely fit upon the guide 30 to.

permit sliding of the feeder 40 thereon. Between the cars 42 portions of the base 41 are turned upward at substantially right angles to the body of the base to form bearings 43 for the pivot rod 44 which supports a sheet metal finger piece 45 provided at either side thereof with downwardly extending portions 46 pivoted on the rod 44. A

i pair of wings 47 extend rearwardly from the finger piece 45 to serve as stops to prevent the finger piece 45 from being turned too far by the spring 48 when released from the operators fingers. A portion struck out from the finger piece 45 is bent'downwardly and rearwardly under the rod 44, then upwardly to contact with the main finger piece to form the gripper jaw 50.

When the finger piece 45 is grasped by the operator and pushed down the finger piece turns on the pivot 44 and the member 50 is brought down through the slot 31 to grip the strip 11 between the member 50 and the base 41 so that as the feeder 40 is pulled down the guide 30 the strip ofpaper is fed forward under the knife 60 and.

through the moistener 80. When the hand is removed from the finger piece 40, the spring 48 releases the gripper jaw 50 so that the feeder may bereturned to its starting point preparatory to feeding a new strip. To automatically return the feeder a coil spring 53 is secured at one end to the feeder and at the other end to a point 54 on the machine frame and is passed over a pulley 55 near the top of'the machine.

The cutter is turned over at its top to form a finger pressure plate 60 and the cross piece-61 is secured to the frames 20 by the screws 62 to form the lower" blade of the cutting device and to. act as a support for the lower end of the guide 30, a projection 63 extends outward from the cross piece 61 to form a support for the cutter 60 which is pivoted thereto by a' bolt 64 which also serves as a supportfor the cutter raising spring 65. A coil spring 67 is attached to the cutter 60 at the end remote from its pivot, and to the frame 20 at a point 68 for the purpose of holding the edge of cutter 60 firmly against resents which the brush 85 projects and it is also 81 is provided with an opening 82 from s provided with a projection 83-which serves j to guide the brush 85 to its proper place and to hold it in operative position, when the brush 85 is dropped into the. opening 82. To bring the paper strips gummed surface into positive contact with the-hairs of brush 85, aweighted metal flap 88 is pivoted at its corners to the brackets 28 by means of the screws 89. a

Secured to the underside of cross piece 61 is a guide plate 91. When the brush 85 and the container 81 are-in position, the brush hairs are supported near their ends in such manner that the weighted flap 88'presses the paper strip firmly against the brush hairs.

The butt end of the'brush extends into the V water in the container 81 and the brush hairs form a capillary moisture conveyor which keeps the brush hair ends continually supplied with moisture which the hair ends individually spread upon the gummed surface of the paper strip. The positive pressure of the weighted fla 88 holds the paper strip against the natura resilience of the 'brush hairs, each hair end reaching a difierent point in the width of the paper strip, even and complete moistening is thus assured. The unavoidable unevenness and indentations in the strip surface, which would prevent even moistening in a roller moistener, do not effect at all the evenness of the moistening as performed by the improved brush moistener herein described.

To hold the container 81 in the frame and to permit ready withdrawal of the same a latch 93 pivoted on the screws 89 is provided. A. curled lip 95 on the container provides a hand grip by which the container may be drawn from the frame.

For convenience in withdrawing a measured length of strip the machine may he provided. with a scale 57 as illustrated in Figures 8 and 9, and the strip'feeder 40 may be provided with a pointer 40 by which the scale may he read. V

Suitablemarkers 58 ma 7 e provided to frictionally engage the scale portionftb mark any desired length of strip, and where the packages being wrapped necessitate strips of different length markers of different color may be applied to the scale to assist the operator to return the strip feeder to the proper point to feed out the desired length. v For automatically stppping the return of ment of the feeder.

the feeder 40 in position to feed out length of strip -Which is less than the length .of the guides 30 a stop 96 be provided, comprising a base portion 97 adapted to be positioned below the guide and to support a cushion pad 98 against which the base 41 slotted under portion of the guide 30 in such vice isplaced, but provide a non-slipping.

a way as to permit the paper strip to move in one direction only. i

The operation of the device shown is best described by reference to Figures 1 and 2. The strip serving device is usually mounted upon a desk or counter of such height as to be approximately at the end of the operators arm as it hangs from his shoulder.

Frames 20 are preferably cast with feet 22 having key shaped slots 23 into which rubber strips 24 are inserted to provide sup ports which will not scratch the surfaces of.

the desks orcounters upon which the decontact with finely finished damage thereto. I

To serve a section of paper strip, the operator reaches forward and upward, grasps surfaces without 7 the finger piece as indicated at 100. The

weight of the operators hand depresses this finger piece 45 and forces the jaw downward, clamping the paper strip 11 againstthe gripper base 41 as shown in Figure 3.

The operator then sweeps his hand downward in a natural swing to the position indicated at 102 in Fi ure 1-, this pulls paper strip 11 from the roll 10 over the apron 32 into the guide 30 and at the same time pushes the length of strip in the guide 30 under the cutter 6.0 through the moistener and projects the strip therefrom .as indicated by the dotted lines at 104. The operator then merely raises his fingers to release the finger piece 45 whereupon the spring 48 releases the grip of the' jaw 50 on the paper strip and spring 53 draws the feeder back to its ori inal position at the top 'of the guides. arm the operators fingers strike the pressure plate 60*, as shown at 106 and the slight pressure depresses the cutter 60 to sever the paper strip. The end of the strip will, however, be held by the flap 88 and the brush until withdrawn by a further movement on the part of the operator.

It is' to benoted that the slope of the ith the continued swing of hisguide 30 is approximately'tangent to the are through whichonels hand will travel when swinging naturally from the shoulder, and

- that by a natural swing of the arm and hand the finger piece 45 is depressed, thestrip fed forward,' the cutter operated and the hand swung out to receive and apply the moistened strip which has been projected from the machine.

By thus; providing a machine which may be operated by the natural movement .of the hand, the fatigue to the operator who stands at the machine wrapping packages all day, is materially lessened and the number of packages which he is able to wrap.

per unit of time is also increased. The use ofan inclined guide 30 instead of a hori' zontal guide permits the use of a longer guide than is possible in a horizontal guide machine, without increasing the overall length of the machine.

The length ofthe travel of strip feeder 40, and hence the length of paper strip projected at one complete stroke may be controlled by shifting the stop 96 but it will be understood that a number of strokes, or only a measured portion of one stroke may be performed to project the exact length of strip required before the cutter 60 is operated.

Thus it' will be seen that means have been provided for projecting measured adjustedlengths and that this same means is operable to project any other length desired withoutdisturbing the aforesaid adjustment.

As only one hand is required to operate the strip projecting, moistcning and cuttinginvention reveals many improvements in paper strip serving and that the ratchets, gears, levers and rollers previously associated with such mechanism have been dispensed with, that the elimination of the complicated and intricate mechanism has so simplified the device that its is adapted to a far broader held of use with greater efficiency in any field.

It is, of course, understood that the embodiment'shown is for illustrative purposes only and that changes and modifications may be made in the complete mechanism or in the parts which form the elements thereof, without departing from the spirit of the invention of the scope of the appended claims. v
