This invention relates to gummed tape serving machines and the present application is a continuation in part of my prior application on package sealing machines filed Jana nary 23, 1928 and bearing the Serial No.

One importantobject of the invention is I toprovide an improved and simple-construe tion of such machines embodying a compartment for. containing a paper roll, a service A fourth important object of the invention is to provide an improved roller feed for forcing the tape from the machine.

A fifth important object of the invention is to provide an improved means for freeing the tape in case it becomes stuck to the guide plate of the machine. A sixth important object of the invention is to provide an improved arrangement of feed roll and anti-retracting pawl for such machines.

A seventh important object is to provide improved means for preventing the doubling and buckling of the tape being fed from the machine. --..f A

An eighth important object oftheinven tion is to provide an improved arrangement of moistener'in such machines.- With the aboveand other objects in view. as will be presently apparent, thezinvention consists in general of certain novel features of construction and combinations of parts hereinafter .l-full y described, illustrated in the accompanying claimed.

' In-thepresent embodiment of theinvention there is provideda body having a hollow semi-cylindrical rear portion 10, forming the lower half of'the paper roll compartment, 0

'andhavin'g a wider forwardpoiftion form-;

ing a liollowrectangular water well 11. The Q top edges of the side wallsofthewell l1 slant downwardly towards the 7 front and at the inner angle of. each topedge there is pro the edges aresomew-hatshorter than the -rabvided a r'abbet 12 which receives the sideedges, of a1 guide or hearing plate which edges are notchedat their forward corners sothat w and backward motion. This well is preferably termed the service compartment of the device as it is hrelthat the tape is treated to make it adhere and-here it is cut or torn off. It is here to be noted that the plate 13 does not fully cover the well 11 as the front edgeofthis plate is spaced from'the front wall of'the well. The purpose of this is topermit the upward projection, as in 2, of the end of a brush 1e havin a heavy band or binding 15 which holds the band portion of the brush submerged and prevents any:

The top'or cover consists of a rear hollow semisoylindrical portion 18 forming the upper half of the paperroll compartment, and

a flat forward portion 19 covering the plate 13. From the rear of the part 18 at each side thereof hingeflugs 20 project downwardly and rest against the" sides of the part 10 to which they are pivot'ally secured by the bolt '21 so that the cover may swing up on these screws to permit the insertionof a roll 22 of gummed tape in its compartment. The plate 19 is provided with depending lateral flanges 23'which terminate short of the front edge of the part 19 for purposes to be set forth and which engage the side walls of the well 11 to hold the front of thecover against lateralmovement. Also the part 19 is provided with slots24; to receive pins 25 projecting upwardly from the plate 13 and thus assisting in maintaining the proper position of the parts as well as limiting the forward and backward movement of the plate 13.-

Across the plate or part 19; on its underforwardlportion extends thecutter; bladeor severing blade 26 which preferably has both edges serrated as shown in order that :the blade 'may be turned end for end to present a new serrated edge when the first edge becomes worn or dull.

length and this'blade is held in position'by fiat headscrews 27 as' in Fig. 9, or by head thumb screws 28 as 'inFig. llptheforward corners of the 'plate;.13;be ing cut away' to" provide'space lfor the screw. heads in the. latter instance. To provide for the better holding of the 'screwsthe part19' has up-' 7 wardly extending bosses 29 into which these t Whenever alength 0f t up needed V V for'use the rollers 38 are rotated as before, are extended'downwardlyto liealon-gsideof set forth which-causes the tapeto pass for screws"engage. Theend's 30 of the blade 26 a The forward serrated, edge of the blade projects slightly in front of the front edge of the part119f for proper action on the'tape in tearingiofi the required the side walls of the well 11 and are pro- Vided with openings 31 engaging over pins or lugs 32 projecting outwardly from these side walls, the lower ends of the tabs 30 being curved away from the walls to permit these tabs to spring and ride over the pins 32 upon closing the device. Obviously the spaced that they may straddle the bar 34 and these sections may be moulded from solid elastic rubber as shown in Fig. 6, or may be formed on a core 39 as shown in Fig. 5. In all cases it is preferred that the rollers be corrugated or ribbed and these rollers drop through the slots 33 to reston the tape &0

which is guided between the pins 24-'25,so

that placing the fingers on the tops of these rollers :and pushing'backwardly rotates the rollersto' force the tapeforwardly; the slots 36 permitting the rollers to be forced firmly against the-tape. In-this action, if the tape adheres to. the guide plate 13, as sometimes happens in damp weather the plate will move forward with the tape but will suddenly stop upon reaching the ends of the rabbets or the pins 25 reaching the forward ends of the slots 24.. The jar resulting from this stopping of the plate is found efiicient to break the adhesion of the tape-and permits its free forward movement. Also the bar 34 prevents the tape doubling up and the doubled portion passing upwardly in front of the rollers as would be thecase if the slots 33 were replaced by a single slot of the same lateral 7 dimensions as the pair.

Just forward of thesl'ots 33 1s a transverse slot 40'Wl110l1 receives thelower edge of a forwardly inclined pawl blade 41 having.

arms 43 ournalled on the shaft 37 either outside the lugs 35 vas shown in Fig. 10 or between said lugs as shown in Fig. 1. This pawljbladeprevents retraction of the tape by reverse movement of the rollers so that:

mischievous persons cannot force the-tape back to render the machine inoperative-until it is re-threaded norjcan such iactlonxoccuraccidentally.

cover lifted and a roll'of' tape placed in the In operation the tabs 30 are released, the

ward over the brush, the forward upturned edge of the plate 13 holding it firmly against the brush so thatit is well moistened. The

' projecting end may now be grasped by the user and as much tape as is needed drawn out and tornofl by aid of the serrated blade.

Notches 41 are formed in the sides of the rear wall of the water receptacle to provide for overflow and prevent the water, if it overflows, from running into the roll holding part of the machine. p

In the modificationshown in Figures 15 and 16 the parts are much like thoseillustrated in FiguresS and 10 but in place of the sectional rollers 38 there is provided aroller 4-2 which is of the same shape and size from end to end and which extends through a slot 43 in the plate 19, this slot being. without the dividing bar or stop bar 34. I

In the modification shown in Figure 17 the parts are much like those shown in Figure 2 except that in place of an inclined brush 14: the brush 44 is arranged to stand straight up, its ferrule or back 45 fitting between the front of the casing 11 and a lug or stop 46 so that the brush is held vertically when in position. This brush, like the other, has an inclined or beveled top so arranged that the web 40 is pushed upwardly as it moves out and is thus in position to be grasped by the forefinger and thumb of one hand of the operator.

There has thus been provided a simple and eilicient device of the kind described and for the purpose specified. V

It is obvious that minor changes may be made in the form and construction ofthe invention without departing from the material spirit thereof. It is not, therefore, desired to confine the invention to theexact form herein shown and described, but it is desired. to include all such as properly come within the scope claimed.

Having thus described the invention, what is claimed as new, is
