Patented Jan. 17, 1933 UNITED STATES PATENT OFFICE LOUIS LINK, 01E NEWYORK, N. Y., ASSIGNOR, BY IVIESNE ASSIGNMENTS, TO NASHUA GUMMED & COATED PAPER 00., OF NASHUA, NEW HAMPSHIRE, A CORPORATION OF MASSACHUSETTS GUM'MED TAPE. SERVING MACHINE Application filed October 15, 1927. Serial No. 226,366.

fective construction which can be made at low cost. Another object is to provide a shear having a lower movable blade which is pressed laterally against the fixed blade in a suitable manner to cut properly Another object is to provide an operating lever which by a single direction movement, first feeds and moistens, and then cuts the tape into desired lengths, the lever being returned to original position by a springand the cutting device being returned to non-cutting position by another spring. Another object is to provide very simple effective tape feed rollers. Another object is to provide a cover which conceals much of the mechanism and which also presses the tape down onto the moistening device. Another object is to provide a simple effective adjustable tape and tape roll guide device to accommodate and properly position tape rolls of different widths. Another object is to provide a tape roll guide and presser arm device to aid in properly positioning and holding the tape roll.

The above and other objects which will hereinafter appear, are attained by the new and useful improvements disclosed in this application. To enable others skilled in the art to fully understand the essential characteristics of the improvements, drawings illustrating one mode of carrying out the invention have been annexed as part of this disclosure.

Fig. 1 is a plan view of a machine for carrying out the invention, with certain 'parts removed for clearness.

Fig. 2 is a right side elevation of Fig. 1 with the rightside plate removed, \and certain parts in section.

Fig. 3 is a fragmental front elevation illustrating the shear'in full cutting position.

Fig. 4 is an enlarged sectional view of the adjustable paper guide on line 4-4 of Fig. 1.

Fig. 5 is a right side elevation of the machine.

Fig. 6 is a front elevation of the machine with the cover swung up and with the water tank removed.

Fig. 7 is a sectional view on line 77 of Fig. 2.

Fig. 8 is a perspective view of the pawl and release mechanism.

The main frame of the machine comprises side members 1, 2 and bottom members 3, 4. Side members 1, 2 are preferably of sheet metal and have supporting feet 5 provided with rubber members 6. Side members 1, 2 are connected together at the front by means of the bottom member 4 having lugs 7 connected to members 2 and lug 8 connected to member 1. Screws 9, 10, together with spacing pins 11, 12 'connect the sides 1, 2 at other places in a well known manner. member 3 has lugs 13, 14 engaged about pin 12 and then extends down and forward as shown in Fig. 2, terminating adjacent fixed shear blade 15 where it is connected by screws 16 to lugs 17 of side members 1, 2. Also secured by screws 16 is a tape guide plate 18 having its central portion spaced above memher 3 to provide passage for the tape, and having its rear curved upward to form guard 19.

Member 3 is cut away at 20, 21 to permit guide discs 22, 23 to be adjusted to different positions on pin 24 pivoted in side members 1, 2. As best seen in Fig. 4, pin 24 has a plurality of annular grooves 25 to accommo- Bottom date balls 26 pressed by springs 27 in holes 28 extending diametrically in discs 22, 23.

By pushing discs 22 and 23 longitudinally of pin 24, balls 26 will move out of certain grooves 25 against action of springs 27 and when the discs again reach a position over any of the grooves 25, the balls 26will be snapped into locking position again by springs 27. Pivoted to pin 12 by ears 29, is a roll post tioner and guide in the form of a presser arm '30 carrying a pin 31 and adjustable discs 32,

33 similar to pin 24 and discs 22, 23. Pin 31 of this presser arm engages a tape roll 34 somewhat to the rear of its top and by action of spring 35 presses the tape roll 34 down and forward against 'pin 24, the discs 22, 23, 32, 33 having been adjusted to span the tape roll. The tape roll is thus held in a constant position and alignment without being per mitted to move about while the tape unwinds.

Fixed shear blade 15 is secured to side members 1, 2 by having one end 36 rectangular in shape and entering a corresponding slot in ear 37 on side member 2. The other end is connected by bolt 38 to car 39 on side member 1. The movable shear blade 40 is also mounted at one end on bolt 38, but is freely pivoted thereon. Blade 40 has a slot 41 engaged by pin 42 on shear lever 43 which lever is pivoted to ear 44 of member. 4 by bolt 45. Shear lever 43 has an angled extension 46 adapted to be engaged by abutment pin 47 or like reinforcement mounted in oper-.

ating lever 48. Spring 49 extends between shear lever 43 and the pin or the like 50 in such a direction as to pull shear lever 43 and consequently blade 41, laterally, to at all times maintain a good cutting action of blades 40, 15, and at the same time to normally act on shear lever 43 to cause blade 41 toresume non-cutting position. It will be seen that as shear lever 43 travels along blade 40, the point of lateral pull on blade 40 gradually shifts in the direction of the free end of the blade 40 as the point of cutting action approaches the same free end. Thus at all times good cutting action of the shear blades is maintained.

Removably resting on member 4 is a water tank 51 having a downwardly extending tongue 52 bent at 53 to provide a seat for the end of brush 54. Lip 55 extends as shown enough room is provided for inserting brush 54 into tank 51, and no more, to prevent undue tendency of water slopping out of the tank when being handled. WVater ascends brush 54 for moistening the tape.

Guide plate 18 is cut-away at 56 to accommodate knurled feed roll 57 mounted on pin 58 which is sufliciently thin and inherently resilient to press feed roll'.57;, sufliciently firmly against another knurled feed roll 59 extending up through slot 60 in member 3. Lower feed roll 59 is secured on a shaft 61' operated by gearing as shown, from gear 62 rigidly secured to ratchet 63 andboth mounted to freely turn on shaft 64. Rigidly secured on shaft 64 is a ratchet arm 65 carrying a pivoted pawl 66 normally urged by spring 67 into engagement with ratchet 63. When pawl 66 moves to a certain position, it strikes a pin 68 fixed in side 1 which causes pawl 66 to be disengaged from ratchet 63, thus ceasin to turn knurled feed roll 59.

ecured to the rotruding non-circular end 69 of shaft 64 is the operating lever 48, previously mentioned, secured by taper pin-70 or other suitable means. Mounted in a curved slot 71 is a headed limit bolt 72 carrying pointer 73, limit bushing 74, knurled adjusting nut 7 5, and cover nut 76. Thus by means of bolt 72, the upward movement of operating lever 48 can be limited as desired. Lever 48 is normally urged upward against bushing 74 by means of coil spring 77, see

and bottom 3. On release of arm 30, roll 34 tends to be pressed into position as shown in Fig. 2 against pin 24. The tape end is led between knurled feed rolls 57, 59 by pressing down on operating lever 48 which feeds the tape out'between parts 18 and 3, to fixed shear blade 15. Operating lever 48 is then released and spring 77 swings it up until its strikes limit bushing 74. By means of knurled nut 75, bolt 72 carrying limit bushing 74 is adjusted for any length of cut desired. Tank 51 is filled with water and brush 54 inserted and the tank is placed in position in the machine, which is now ready to feed, moisten and cut strips of gummed tape of uniform predetermined length.

By depressing operating lever 48, since pawl 66 is in engagement with ratchet 63, the tape is fed forward until one end of pawl 66 strikes against fixed pin 68, causing the toward brush 54. It will be seen that just 'p awl to be released from ratchet 63, and the feed of the tape now ceases although lever 48 is pressed on down. Presently pin 47 of lever 48 engages end 46 of shear lever 43 and swings movable shear blade 40 to sever the tape. On release of operating lever 48, the operating lever is first moved upward by action of both springs 77 and'49 until shear lever 43 returns to normal position. From this point upward, the operating lever 48 is moved by spring 77 alone, until the lever strikes limit bushing 74, when the machine is again ready to feed, moisten and cut another strip of tape of the same length as the first one. In operation, the strip of tape is pushed part way over the moistening brush 54 and when grasped by the fingers and pulled out-to. be used, the remainder of the strip is moistened as it passes over brush 54.

The invention may be embodied in other specific forms without departing from the spirit or essential characteristics of the invention, and the present embodiment is therefore to be considered in all respects as illustrative and not restrictive,the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of e uivalency of the claims are therefore inten ed to be embraced therein.
