TAPE-F EDING MACHINE. I

Application filed May 9, 1927. Serial No. 190,052.

My invention relates to improvements in it consists in the combinations, constructions and arrangements hereinafter described and claimed.

An object of my invention is to provide a tape feeding and mois ening machine in which novel means is actuated by the tape feeding means for automatically cutting off the tape when. the tape feeding means manually released. v.

A further object of .my invention is to provide a device of the type described which makes use of novel means for moisteni'ng the tape.

Other objects and advantages will appear in the following specification, an'dthe novel features of my invention will be particularly pointed out in-the appended claims.

My invention is illustrated in the accompanyingdrawing forming a part of this application, in which- Figure 1 is,a to plan view ofthe device, a portion thereof Being broken away;

Figure 2 is a side elevation of the device;

Figure 3 is a section along the line 33 of Figure 2; and

. Figure 4 is a perspective View of a portion of the device. I

In carrying out my invention I provide a frame 1 which has an open side 2 in which a roll of tape 3 is mounted, the tape being supported by a'bolt 4 and being held in place by a spring washer 5 against which a thumbscrew 6 bears. The pressure of the washer 5 against the roll of tape may be varied at will.

The tape is protected from dust and the like by a curved rim 7, this rim being secured to the frame by a fastenin device 8, (see Figure 2) and having its ot er end secured to the front of the machine at9. If desired the rim 7 may bewelded or soldered to the frame 1.

The tape 3 is fed through a carrier 10, which is hinged to therim 7 at 11 (see Figure 3) and which is therefore adapted to rock and through the tube 12 when the wheel is rotated.

. The means for rotating the wheel comprises a crank handle 18, which is carried by a hub 19 and which carries a pawl 20. This pawl engages with a ratchet 21 integral with the wheel 15 when the crank handle is swung in a counter-clockwise direction in Figure 2. This movement of course causes the wheel to feed the tape. a

' In Figure 3 I show the hub 19 as housing a torsional spring 22, this spring having one of its ends secured to the hub at 23' and its other end secured to a supporting bolt 24. The spring 22 is tensioned when the handle 18 is moved and as soon as the handle is released the sprin will return it to the posi-' tionsho-wn in igure 2 and will cause the I pawl 20 to ride over the ratchet 21 prior: to

the next engagement therewith.

It will be noted from Figure 2 that a spring 25 connects the carrier 10 with the frame 1 so that the tape 17, will be forced down against the wheel 15. One of the objects of the present invention. is to provide means for spacing the tape 17 away from the handle 18 will be to free the lug 27 thus permitting the spring 25 to move the tape 17 down into contact with the wheel 15. The

.tape 17 is fed through a moistening device shown in Figures 1, 2 and 4, this device comrising a container 28 hinged at 29 to the rame 1 and carrying a moistening member 30 (see Figure 4) This member is U-shaped and has its legs 31 disposed in openings 32,

the legs then extending down into the compartment 33 which is kept supplied with water by the container 28 The U-shaped.

member 30 is preferably made of wick material so that the liquid willkeerr the member moist by capillary attraction. Of course, the moistening member 30 is flexible and I therefore support it by a U-shaped member 34, preferably made of metal. The ta 17, gum ned surface uppermost, is passe over the top of the com artment 33 and beneath the moistening mem r 30 and the member-30,

due to its own weight and to the weight ofthe member 34, bears against and moiiten's -chine.- I

from time to time through the inlet openthe latter prior to its passing from the ma- The container 28 is filled with liquid 7 .ing '35. 1

The container 28 is pivotally secured at 29 for the purpose of removing the member 30 when desired,.and for the purpdse of re-- moving a cutting blade 36 when desired.

Figures 1. and 3 clearly show how the container 28 is pivoted with a hook 37 that drops ''the hook 37 whereupon the container is free the dotted line position to be swung into shown in Figure 1.

The blade 36 of the carrier '10 and its cutting edge 39 is disposed directly beneath the tape 17 so that a swinging of the carrier 10 in'a counterclockwise direction about the pivot 11 in Figure 2 will cause the carrier to move the tape past the edge 39, 'whereu on the tape will be severed. A spring 40 cars against the blade 36'and keeps the edge 39 in contact with the end of the carrier 10. This assures a shearing action for providing positive means for cutting the tape. -It should also be noted from F1 ure 4- that' the spring 40 has its upper en of a shoulder 41 formed in the blade 36.,

This construction prevents the blade 36 from being accidently moved upwardly as the car- 'rier 10' moves back into normal position. From the foregoing descript1on of the .various parts of the device, the o eration thereof may be readily understood. s heretofore stated the tape has passed through the tube 12 and beneath the member 30 as clearly shown in Figure 2. If now it is desired to use a portion of the moistened tape, the handle 18 is actuated for causin the wheel 15 to. feed the tape and the hen e'is reciprocated the desired number of times for feeding a piece of tape oft'the required length. As heretofore mentioned the member 10 brings the tape 17 into contact with the wheel 15 upon the initial movement of the handle 18. After the desired amountof tape has been moistened and the operator wishes to sever the tape, he merely releases the handle 18 whereupon the spr ng 22. will rapidly swing the handle in a clockwise direction with sufiicient force for causing the pin 26 to strike the lug 27 and to swing the carrier 10 in a counter-clockwise direction againstthe tension of the spring 25.- The move ineht causes the carrier to move the tape past bears against the outer end bearing against the top strong enou h toremove the carrier from the .v

wheel and t e tape therewith until the handle 18 is again actuated.

The device is particularly simple in con-- struction and provides novel and eflicient means for preventin the tape from adh'e ring to the tape feed'ng wheel and for automatically cutting the tape from the roll when 'the operating handle is released.

I claim: 1. Adevice of the type described comprising'a tape carrier, tape feeding means, means for causing said carrier to bring the tape into contact with the feeding means, atape cut ter, and meanscar ried by said feeding means and 'said carrier for causing said carrier to movethe tape past the cutter for severing the tape when said feeding means is suddenly released.

2. A vdevice of the type described comprising a tape carrier tape feeding means, a cutter, said carrier b ing the tape 'into contact withthe feeding means or 'into contact with the cutter and manually controlled'means'for actuating said feeding means and for selectively causing said carrier to bring the tape into contact with the feeding means or into operative position withthe cutting means.

3. A device of the type described compris-' ing means for supportlng a roll of tape, a tape guide, a cutter disposed adj acent to said guide, tape-movin means cooperating with said guide for moving the tapeitherethrough, a spring connected to and adapted to be placed under tension when said tape-moving means is moved in one direction, said means when released adapted to be moved b said spring and to actuate said tape gui e for moving it past the cutter, whereby the tape is severed v 4. 'A device of the t e described com rising a pivotecLtape lde a cutter associated therewith means a apted to be manually reciprocated for moving tape through the guide,-a spring connected to and adapted to eing movable for bringdenly released, the rocking of said guide moving the tape across the cutting knife, whereby the tape is severedr g RUFUS M, BROOKS.
