2 Claims. (Cl. 9141.5)

This invention relates particularly to maof the frame` comprises the base AcastingA' and chines adapted tothe purpose of serving `strips thesurmounting casting A2. ofgummed tape, or the like. Y, Y The main .actuating rock-shaftB isjournaled .The primary object is to `provide `improved in the casting A and may be rocked bymeans.l of

5 `strip feed meansfcoacting in an improved manthe crank or handle B. 'The shaft is urgedin 6e' ner with strip-severing means. a counterclock-Wise direction by a coil spring Inaccordance `with the preferred embodiment 10, one end `of which engages a capped-stud v.11 of thepresent invention, a feed Wheel is jourmounted on the rframe `A and the other endis naled on `a rock-shaft and is `actuated thereattached to a pawl-actuating-arm 12, which,

The main part Fig. 3. The legs 36 of the arm F3 are freely 11-0y which will engage a prong 37a and depress the y cutter-blade when the shaft is rotated beyond a certain position.

The water-font G is of the usual type and supports a moistener which is provided with a presser member 42, serving to press the strip E into engagement with a wick 43.. The font is supported by a plate 44 which is fastened to the base member A by means of machine screws 44a. The front edge of the base member is recessedv to receive a compression spring 45 and a plunger 46 having an upwardly extending lip 46a which may be depressed to remove the font from the machine.

The machine is loaded by placing a roll of gummed paper in the chamber provided in the rear of the machine and a strip E threaded from'the supply roll, between the feed rollers andunderrthe plate 25, to the front of the machine. After filling the font with Water, the machine is ready for operation.

To operate the machine, the handle B is drawn forwardly, which will cause the following actions: the pawl 14 engages the ratchet and causes the feed roll to advance the strip forwardly from under the blade 32 until the tailportion ofthe pawl 14a engages and is depressed by the cam 18, thereby disengaging the ratchet; during that portion of the stroke the'lost-motion arm 40 has been advancing towards the prongs 3'7a 'and just as the ratchet releases, the arm makes contact with the prongs; continuance of the stroke presses the arm F3 downward, and through link F2 and lever F' the blade is lowered and the strip severed. Upon release of the arm B the springs will return the parts to their initial positions, as will be readily understood. It will be noted that during the cutting operation the feed wheel is not operating, and accordingly the strip is not forced to buckle in back of the knife blade.

The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitations should be understood therefrom, but the appended claims should be construed as broadly as permissible, in View of the prior art.

What I regard as new, and desire to secure by Letters Patent, is:

.1. In combinationY in a machine of the character set forth: a frame having a throat over which a strip may be led; an actuating rockshaft journaled in said frame and provided with an arm; a feed wheel and associated ratchet devi-ce journaled on said shaft; a strip-severing cutter; an actuating lever journaled on said shaft and linked to said cutter; lost-motion connections -between the arm on said rock-shaft and said lever; and a cam segment carried by said throat for disconnecting the ratchet device before conclusion of the working stroke of the rock-shaft. d

2. In a machine of the character set forth: a frame having a Awater fount housing and a throat from which a strip may be led over said housing; a water fount mounted in sald housing kand equipped with a moistener adapted to moisten a strip fed thereover; a guide-plate foi` said -strip having a spring-clip adapted to snap onto the side walls of the housing; an actuating rock-shaft journaled in said frame and provided with an arm; a feed-wheel associated ratchet device journaled on said shaft; a stripsevering cutter disposed above the housing; an actuating lever journaled on said shaft and linked to said cutter; lost motion connections between said arm and said lever; and a cam segment carried by said'throat for disconnecting the ratchet device before conclusion of the working stroke of the rock-shaft.
