The gear 21 T m ke the moistening roller and the. feed is also in mesh with a pinion 3| on a shaft 32 rolls effective there are top rolls for each of them. 55 which shaft carries the moistening roll 33. The In order to give easy access to the knife and these 5 rollers and to the tape l 6, I mount the top rollers in a swinging bracket 51 pivoted at 58 to the side walls II and I2. The bracket is relatively heavy and by its weight it holds the tape down in feeding contact with the lower rolls and has the added advantage of allowing the tape to be fully exposed for feeding installation of a fresh roll. The bracket when thrown back remains out of the way until it is manually returned to its forward or lowered position. The bracket has a recessed part 59 for the reception of the movable blade 44 and the upper end of the link 46. The front top roller 60 is adapted to rest on the moistening roll 33 and the rear top roller 6| has a gear 62 which meshes with the gear 63 on the shaft 29 of the rolls 30. a

The roller 60 runs idly but the rear top roller 6| has a gear 62 which meshes with the gear 63 on the shaft 29 of the rolls 30. The bracket 51 can swing freely and is held in place by its own weight and needs only to be lifted to make the rollers and cutting mechanism accessible. The top rollers are arranged with the ends 64 in the slots 65 in the side walls of the bracket 51. They are prevented from falling out by pins 66 and when placed in position over the

rolls

33 and 30 they support the bracket by the springs 61.

To prevent a return slam by the lever l8 when the handle I! is released, I provide a check 68, preferably an air check. The one shown comprises a cylinder with a piston 69 slidable therein. The cylinder has a restricted outlet 10 near its closed end. The closed end is pivotally secured as at H in order that it may rock. The piston 69 has a piston rod 12 pivotally secured to a crank 13 on the shaft 23. The crank is returned to normal position by a spring 14. The check is effective when the lever l8 has nearly resumed its normal position.

This construction is of great advantage because the release of the handle is not accompanied by a jarring of the machine. Such jarring is apt to displace the short length of tape between the feed rolls and the knife and also the roll I 5of tape especially when the roll has become small.

In my machine the return of the handle due to the pull by the spring 14 is unimpeded until the full force of the spring has been operative on the arm 48 of the cutting mechanism. This is necessary to secure a clean and positive cut through the tape. As soon as the cutting has been accomplished the check 68 becomes operative and the final movement of the handle and the clearing of the dog 5| by the trip 5| is cushioned and gentle. The return or normal position of the handle can be altered by the rest 15 which may be selectively placed in holes 16 in the casing 26. A casing 11 is placed over the parts operating on the outer face of the wall H.

The spring 14 and the check 68 are approximately in line with the crank 73 when the handle is fully returned. This arrangement provides a maximum force by the spring when the crank is at right angle to its at rest position when the cutting takes place and a minimum of resistance by the check. As the crank swings to its normal position after the cutting has been accomplished the force of the spring diminishes but the check drives at its maximum resistance. In other words, when the spring is strongest the check is weakest and when the spring is weakest the check is strongest.

I claim:-

A machine for delivering tape comprising a frame, a shaft extending across the frame, a handle on the shaft for rocking the shaft, a tape feeding device, means for actuating the tape feeding device from the shaft on a forward movement of the handle, a cutting means actuated from the shafton the return movement of the handle, a crank secured on the shaft, a spring secured at one end to the machine and at the other end to the crank and approximately in line therewith when the handle is fully returned and a check pivotally secured at one end to the machine and at the other end to the handle and approximately in line with the crank when the handle is fully returned.
