-This invention relatesto improvementsin tape dispensing machine. o

The main object attained in the invention consists in a tape dispensing machine-adapted in allits parts for cheap productionpneat and compact in design, and simple and convenient in use. I

Machines for dispensing gummed tape for sealing packages have come into extensive use. Their economic value as tiine savers, the neatness of appearance and efiective sealing or binding of packageswhich is made possible'with their'use, and the convenient and inexpensive means oiicarrying an advertisement of the establishment ai'iorded by the sections ottape applied to the packages,

gives to machines oi this character me -m tion as a commercial necessity.

As the devices areused 11 great numbers in establishments Where 1 speed in preparin packages is essential, and neatness an d eti ectivene-ss of the packages is required, and

-also'in'small stores where the'fir'st cost 'of the machines" and subsequent servicecostare determining conditions of their use, the improvements of the presentinvention areoi? great importance in the field to which the invention'relates. I *1 1 In the accompanying drawings: Fig. 1 is a side elevation of the improved "Figs. 2and 3 are opposite end elevations;

Figs. 4- and 5 are detailviews of the-tape severing mechanism; 1 3 r r Figs. 6,7 and 8 are detail views of the tape advancing mechanisn'i. r I As shownin Figs.- 1, 2 and 3 the machine as a whole is a compact portable unit adaptcdto set on a counter or table. .Theframe structure consists of opposite sidem'enibers l, punched from sheet metal and formed to give an artistic' effect to the machineg'the side inembersbeing oinedf 'one to the other byspacing bones. At the left end of the machine-as viewed inllig. l a curved guide plate-3- and opposite side guide plates 4 aresuppm't'ed bet-ween the side members 1. At the opposite end. of the machine the side' members 1' are braced between their upper edges by a trans ti-ffen :frame adjacent tape severing anis'm. A longitudinally extended guide 6 is supported betWeenside members 1- along their upper edge, the guidebeing provided on 1ts OPPOSItG'SIClQg edges, as best shown incross section in Fig. with inwardly curved open flanges which are adapted to receive the web 14 oftapetherebetween as the same is drawn forward from a roll supported between the side members. i 1 1 d The means for drawing the consist of a supporting member 7 arranged to slidetelescopically over the guide mem ber6, as best shown in Fig. 7 and having opposite portions 7* thereof 'eXtendedTupwardly to form supports for a pivoted tape engag ng member \COIDPIISXHQ" downwardlyv extended bearingportions 29, a downwardly curved portion '30 adapted to-engage the tape, an upwardly extended finger P1808! 31:,

a rearward and downwardly extended stop 32, a shaft 33 'upon which the part as a whole is supported anda' spring 34L which acts to hold the part inoperatively out of engagement with thetape.

'VVhen tape is to be supplied from the machine, pressure is applied to theafinger piece 31 in the forward direction thus causing the tape to be. gripped between part 30iand the "lower-span of part 71 and at the same time acting to move the entire. unit longitudinally of guide Gwhich results'in drawingthe'length of'tape, to which the machine is regulated, from the supply roll, .the length being regulated .by-stop 39. adapted to 'be set inoneof awseriesaof spaced apertures 40 arrangeda-long the upperedge ot onesot "theside members the stop "being in the path, inside frame 1, ofpart35 and adapted therefore to limit the forward movement er theft-ape advancing mechanism; mWhen stop "39 is removed the maximum length oi? tape that can be delivered from the machine will be determined by the full movementof part 7 tension spring: l'r'ais connected to part 35 at one end, anchoredatits .op'posite'endras at 18-between side members 1-, the intermediate "portion "of" the spring being -drawn over a rotatable drum 1 7 as best shown; :in

As the" tap is drawn from the supply roll the same passes over guide plate i -and roller '4 and under] an ecccntrically i mounted pinch roller 8 pivoted on a shaft 9 support ed in'"brackets extended upwardly from "p1ate3,which acts to engage the tape audio IOU prevent retraction thereof in the opposite direction after each dispensing operation.

lit the opposite end ofthe machine, the right end as viewed in big. 1, tape feed rollers 11 and 13 are supported between side members 1, the web 14' being between the rollers. Roller 11 is supported on a shaft 12 and has its lower portion submerged in a water pan 11 and acts therefore to apply moisture to the gummed sideof the tape. The roller is rotated by means of a chain 16 traversing sprockets 15, the chainbeing drawn forward by means of a spring pawl 37 pivoted on a stud 36 supported in a bracket 35 secured to part 7, a spring 38 acting to cause the pawl to engage a link of the chain when part 7 is moved in the for: ward direction and permitting the pawl to move idly over the chain when part 7 is retracted in the opposite direction.

The means for severing the tape consist of pivoted blade 19 having an upwardlyextended finger piece 10 adapted to be engaged at the limit of the forward movement of the tape advancing mechanism to actuate the blade for severing the tape. Coacting with blade 19is a cutting blade 5 which is secured to bracket 5 and is provided with an upwardly extended portion 24 to e which blade 19 is pivoted by means of a blade adjusting screw and nut 21-22. The blade 19 is held in normally raised relation by a spring 25 and is held yieldingly in cutting relation with the cutting edge of block5 by a spring 27 which is connected at one end to the blade and is anchored at its opposite end to one of the side members 1.

Operation of the machine, as will be apparent from the foregoing detailed description, consists in actuating the tape advancing mechanism with a downward sweep ofthe hand, the hand passing with a short continuous movement in the same direction, upon releasing the tape advancing mechanism to the tape severing mechanism, the arrangement being thus effective with the minimum movement and in the shortest time to'deliver a severed length of tape from the machine. As the tape is severed the portion cut oil is drawn from rollers 1113 and applied to the package, a stripper blade 11 acting to prevent the tape adhering to roller 11.
