30 Claims.

An object of the present invention is to provide a machine of simple construction which may be set to feed and cut off accurately measured lengths of gummed tape or may be adjusted to automatically and continuously feed any desired length of such tape, said measuring means being also adjustable to change the lengths of measured portions within the range of the machine.

A further object is to provide motor driven means for feeding gummed tape and arranged to be automatically stopped by the measuring means, means being also provided to automatically sever the strip when the measured length has been fed out, andbraking means being provided to stop rotation of rolls for feeding the tape, immediately upon the discontinuance of the application of power to rotate said rolls and prevent over feeding of the tape and movement thereof while being severed.

It is also an object to provide means which may be set to discontinue the operation of the measuring means when it is desired to feed an indefinite length of tape or may be set to prevent the control lever from being locked in an 30 inoperative position when the machine is set to feed and cut ofi measured lengths. j

It is a further object to provide such a machine with a single hand operated control lever for starting the operation of the machine, together with mechanism the operation of which is dependent upon the actuation of the control lever, for automatically severing the tape when the desired length has been fed out and for automatically operating a switch to cut off the current from the motor.

A further object of the invention is to provide a completely automatically operating machine for the purpose having certain other new and useful features in the construction, arrangement and combination of parts all as hereinafter more fully described, reference being had to the accompanying drawings in which Figure l is a longitudinal section through the detachable casing or cover of a machine illustrative of an embodiment of the invention and showing the mechanism in side elevation and in normal raised position;

As shown in the drawingsi indicates the. base of the machine upon. which rests a detachable sheet metal casing or cover 2 adapted to enclose. the operating mechanism of the machine and to be removed or lifted off whenever it isdesired to get at the operating mechanism or to place'in position, a roll of tape 3 from which roll 'the tape t is adapted to be drawnand fed out through an opening in the front end of the casing, by the operating of the machine, said roll being mounted'upon 'a shaft 5, which shaft is mounted for free rotation within bearings uponparallel plates 6 forming the sides of a supporting frame mounted upon the base I within the casing 2. 1 I

Supported bythese plates B'adjacent-the for"- wardend of the machine, is a'table 'l'and an upwardly curved guide 8 projects from the forward end of the table. toward an" opening, inflthe cover PATENT 2, this guide comprising spaced apart members of plates, the upper member 9 being curved similarly to that of the lower member 8 and this upper member extends through the opening in the end of the cover and above a brush H), the lower end of which is supported in any suitable manner within a water pan II to keep the brush dampened so that the strip 4 as it is fed out of the machine will be dampened just as it leaves the opening in the casing 21 and be ready for application to the work to which it is to be applied. The strip 4 extends over the upper surface of the table 1 with its forward end extended between the curved guides 8 and 9 so that it,will be projected out of the machine over the brush I as the strip is fed forwardly by a pair of feed rolls l2 and I3, a weight member or plate |4 being loosely set upon the table I between the feed rolls and the forward end of the table to hold the strip down upon the table so that it will not buckle as it is fed forward by the rolls, said weight plate being free to rise but being held against movement longitudinally of the paper strip, by pins l5 set in the table and extending through openings in the plate.

Rearwardly of the feed rolls l2 and I3, is a pair of guide rolls |6 between which the strip 4 is guided in its forward movement, these rolls being mounted in suitable bearings upon the side walls or plates 6 of the supporting frame. Pivot-ally mounted upon the bearing shaft for the upper of the rolls I6 is a pair of forwardly extending arms I! between which the feed roll I 3 is mounted upon a shaft having bearings at its ends on the ends of the arms l1, and therefore by an upward swing of the arms H, the roll |3 is moved away from the roll l2 and out of contact with the tape 4 passing between these feed rolls. This upward swing of the arms I! is effected by means of a cam shaft 8 extending across the supporting frame and having bearings at its ends upon the plates or side walls 6 of the frame, said arms |I being provided with notches intermediate their ends to receive-said cam shaft |8 so that upon rotation of the shaft its cam sidewill be brought into engagement with the upper end of the notches in the arms I1 and swing said arms upwardly against the action of a coiled spring or springs I9 and thus stop the feeding of the tape by a separation of the feed rolls, one or both of which rolls may be knurled to prevent slippage of the rolls in engagement with the tape. A transverse opening is provided inthe table to provide for the lower roll |2 so that its upper side will engage the lower side of the tape as the tape passes over the table and between the rolls l2 and I3.

A-second slot or opening 20 is provided adjacent the forward end of the table to receive a cutoff plateor knife 2| for severing the tape when the proper length has been fed out of the machine between the guides 8 and 9 and this knife 2| is secured to a cross bar 22, one end of which is guided within a vertical slot 23 in a post 24 secured. to one of the walls 6 of the frame, and the opposite end ofthis bar22 is formed integral with the upper end of a slide 25 which is mounted against the outer sideof the other'wall 6 in any suitable manner, as by screws 26 passing through longitudinal slots in the slide. The lower end of this slide 25 is formed with an outturned foot 21 forming a seat for a coiled spring 28 so that the spring will normally exert a force to move the slide upwardly and thus raise the knife 2| and hold the same in up position. The downward movement of the slide and knife is effected by operating mechanism hereinafter described, the slide 25 being provided with an outstanding pin 29 to be engaged by a member of the operating mechanism.

To drive the feed rolls I2 and |3, to one end of the shaft of each roll is secured a pinion or gear 30, which pinions are adapted to intermesh when the upper roll is lowered by the downward swinging movement of the arms upon which the upper roll carrying the upper pinion, is mounted, and secured to the opposite end of the shaft of the roll I2, is secured a large pulley 3| adapted to be frictionally engaged and driven by means of a friction wheel 32 fixed upon the outer end of the drive shaft 33 of an electric motor 34, which motor is pivotally supported at one side by means of a pivot shaft 35 mounted in the walls 6 of the supporting frame and extending thereacross through a suitable bearing therefor at one side of the casing of the motor so that the motor together with the friction pulley 32 upon its shaft, may swing a limited amount to bring the pulley into frictional contact with the friction wheel 3| on the end of the shaft of the lower driving roll I2 and thus transmit driving motion from the motor shaft to the lower feed roll l2 and when the gears 30 on these feed rolls are brought into mesh, both rolls will be positively driven to feed the strip forwardly over the table 1 and between it and the weight plate I 4, and thence beneath the cutting blade 2| and out through the slot in the forward end of the casing in contact with the moistening brush III.

The operating mechanism shown in elevation in Figs. 1, 2, 8, 9, and 12, includes a control lever 36 which is pivotally mounted at its inner end upon a shaft 3'! for free up and down movement and extends forwardly through a vertical slot in the end of the casing 2 and is provided upon its outer end with a handle portion by means of which said lever may be depressed against the action of a coiled spring 38 interposed between the base of the machine and the lower side of the lever 36 to exert a force for normally holding said lever in an up position, said lever turning freely upon the shaft 31. Mounted upon the upper side of this lever 36, is a slide 39 provided with longitudinal slots 40 to receive screws extending through these slots and into the screw threaded openings in the upper side of the lever so that this slide may move longitudinally of the lever in one direction against the action of a coiled spring 4| interposed between the end of the slide and 8. lug extending upwardly from the upper side of the lever. This slide is formed with a lateral projection having a beveled end edge 42 which is adapted to be engaged by a lever dog 43 secured at one end to the shaft 3'! adjacent the control lever 36 to turn with said shaft and this dog has a lateral projection 44 and the forward edge of this projection is beveled to provide a compara tively sharp angle 45 to engage beneath the beveled rear side 42 of the projection or lug on the'slide 39 so that upon depression of the control lever 36, this projection of the beveled side 42 of the lug on the side of the slide, will depress the lever dog 43 against the action of a spring 46 beneath the dog one end of which is secured to the base of the machine. This depression of the control lever 36 which depresses or swings the lever dog 43 downwardly, also turns the shaft 31 by reason of said dog being secured to said shaft, and to release the control lever, said slide 39 is moved endwise from engagement with the sharp end of the dog 43,'by means of a pointed lever 41secured upon the end of a transverse shaft 48 which is mounted in bearings on the side walls 6 of the supporting frame and extends through these walls at each end and this pointed lever 41 is normally held in a substantially vertical position with its pointed upper end in a position to engage within a notch 49 in the inner side of the slide 39 when the control lever 36 is depressed a certain distance and by engagement with one side of the notch will move the slide longitudinally against the action of its spring 4| when the shaft 48 on which the lever is secured, is rotated to swing said lever 41 toward the forward end of the machine, thus moving the slide forwardly and releasing its projection 42 from engagement with the pointed end 45 of the lever dog 43 To hold the lever dog 43 swung downwardly to the limit of its movement, a latch lever 56 is pivotally attached at its lower end to the adjacent wall 6 of the supporting frame and this latch lever is normally swung toward the projection 44 on the lever dog, by means of a coiled spring 5| so that upon the lever dog 43 reaching the lower end of its swinging movement, this latch lever 50 will engage over the projection on the lever dog and hold it in its down position. This latch lever 56 is also formed with a laterally extending lug 52 on its forward edge and this lug 52 projects into the path of swinging movement of the pointed lever 41 so that upon forward swinging movement of said pointed lever 41, it will come into engagement with this lug 52 and swing the latch lever 50 forwardly to disengage 'it from engagement with the projecting end portion 44 on the lever dog 43, thereby permitting said lever dog to turn upwardly.

There is also provided a swinging latch or dog 53 which is pivotally mounted at its lower end as at 54 within a bearing upon the base of the machine for swinging movement parallel with the lever 41, it being positioned between said lever 41 and the inner side of the control lever 36, said latch 53 being normally held swung rearwardly toward the lever dog 43 by means of a coiled spring 55, said dog 53 being adapted to swing rearwardly and engage over a pin 56 projecting from the inner side of the control lever 36 when said lever has reached the lower end of its downward swinging movement and thus hold said control lever in that position. To release the latch 53 from over the pin 56, said latch is provided with a laterally extending lug 51 at its upper end and forward edge to project into the path of swinging movement of the pointed lever 41 when said lever is swung forwardly and thus engaging said lug 51, swinging said latch 53 out of engagement with the pin 56 'to permit quick upward movement of the control lever 36.

This latch 53 is also provided with a lug 58 projecting from its rear side and laterally of the latch and is adapted to be engaged by a longitudinally movable pin 59 which is mounted for sliding movement within a suitable bearing 60 mounted upon the base of the machine. This pin 59 is provided to swing the latch 53 forwardly and out of the path of movement of the pin 56 on the control lever so that said control lever will not be held at the lower end of its movement by the engagement of said latch with said pin, and to move this pin 59 endwise and hold the latch in inoperative position, a cam member 6| is mounted upon the end of a shaft 62 extending through bearing openings in the walls 6 of the frame transversely of said frame andv out through an opening in a lug on the base at the side thereof opposite that at which said cam is positioned, and this shaft 62- is'provided upon its outer end with a knurled head 63 by means of which the shaft may be rotated by hand. Sleeved upon the shaft 62 between the head 63 and the lug on the base through which the shaft extends, is a coiled spring 64 which spring normally exerts a force to hold the shaft moved endwise with a sleeve 65 secured upon the shaft inwardly of the bearing lug for the shaft, which sleeve will thus be normally held in frictional contact with said bearing lug and resist rotation of the shaft 62 to hold said shaft in the position to which it is turned. This sleeve is formed with an annular groove 66 to receive a fixed pin or member 68 on the shaft 62 when the shaft is turned without being pressed inwardly against the action of the spring 64, or will follow the cam 61 by pressing inwardly on the shaft and then by turning the shaft, said shaft will be moved endwise by reason of the engagement of the member 68 withthe cam surface 61.

When the control lever 36 is moved to the lower end of its stroke, that'is, when the machine is set to sever measured lengths of tape, andthe slide 39 has been moved endwise by the pointed lever 41, the operator may perhaps not release the control lever 36 immediately upon its reaching the lower end ofits stroke and if he does not do so the pm 56 will be released fromand ated' until released by the turning of-the cam shaft 62 and the longitudinal movement of the pin 59, which will swing the latch 53 and release the control lever. is being operated to cut off short measured lengths of tape it is advisable to throw the latch member 53 out of operative position by means of the turning of the cam 6| so that the control lever will not be locked in down position.

To movethe slide 25 which carries the knife 2| with'a quick downward movement in severing the tape, a suitable pawl 69 is pivotally attached or mounted intermediate its ends upon the adjacent wall 6, with the long end of said pawl projecting across the outer face of the slide 25 where-it is Therefore when the machine held normally in contact with the pin 29 on said described, this sharp angle 45 will snap past the,

lower angular end 1| of the lever pawl 69 and when said leverdog is released by the latch lever 59 it will be swung upwardly by its spring 46 and its sharp forward end 45 will engagebeneath the end 1|, and rock said lever pawl upon its pivot forcing its long end downwardly against the pin 29 on the slide 25 and thus move the slide and the knife 2| with a very quick stroke to sever the tape.

With the parts in rest position as shown in Fig. l, the-friction wheel 3| is held against rotation, by means of a brake shoe 12 carried by an arm 13 which arm is attached to a lug 14 pro-- jecting rearwardly from the rear end of the lever dog with said arrnextending longitudinally of said dog and forwardly in a position to bring the brake shoe carried thereby into contact with'the periphery of the friction pulley 3| when said lever dog is in its upwardly swung position and therefore whenever the control lever is operated to start the operation of the machine and the parts have operated to feed a length of tape and cut it off, the rotation of the friction disk 3| due to inertia, will be immediately stopped by the friction shoe 12 coming into contact with its periphery and therefore there will be no overrunning movement to cause a feeding of the tape beyond the desired length, thus insuring the cutting off of accurately measured lengths.

Pivotally attached to the rear end of the lug 14 is a block 15 on the lower end of a rod I8,

the upper end of which rod is pivotally connected to the free end of an arm 11 secured at its opposite end to the end of the cam shaft l8 which as before described is arranged to extend across the table 7 beneath the two arms I! which carry the feed roll l3 upon their forward ends and, therefore whenever the lever dog 43 is released and swings upwardly into contact with a suitable stop or buffer 18, this swinging movement will exert a downward pull upon the rod and through the arm 11 will rock the cam shaft I8 and lift the feed roll l3 out of engagement with the tape.

At the same time, this upward swinging of the lever dog 43 will operate an electric switch indicated at 18 and shut off the current from the motor 34, said switch as shown in Fig. 11 being provided with a snap lever having a ball head on its outer end to engage within an opening in the lever dog 43 so that upon swinging movement of the lever dog upwardly, the current to the motor will be out off and when said lever dog is swung downwardly by the operation of the control lever 36 as previously described, said arm of the switch 18 will be swung downwardly and connect the motor to the: current supply lines (not shown). Therefore the movements of the lever dog operate to turn the current on and off to start and stop the motor automatically.

To automatically swing the motor 34 upon its pivotal support 35, a clamp member 8| is clamped firmly to the shaft 31 opposite the side of the motor body and this clamp is adapted to engage a projection 82 on the side of the motor body opposite that at which the pivot therefor is located, and therefore, when the shaft 31 is rotated in one direction by the downward swinging movement of the lever dog 43, the projecting end of this clamp will engage beneath the lug 82 and swing the motor upwardly together with the friction pulley or wheel 32 which is mounted upon the end of the motor shaft, to bring this friction pulley into frictional engagement with the large friction pulley 3| and thus transmit driving power from the motor shaft to the shaft of the lower feed roll I2 which, in turn, will through the intermeshing of the gears 38 upon the ends of the feed rolls l2 and I3 drive these rolls in contact with the tape and feed the same forwardly with a rapid movement depending upon the proportional diameter of the two friction pulleys and the speed of the motor, the two gears 30 being brought into meshing engagement at the proper time through the operation of the cam shaft I8 which is rotated by means of the connecting rod 16 attached at its lower end to the rear end of the lever dog 43.

The mechanism for accurately measuring the lengths of tape to be fed out of the machine and cut off, comprises an adjustable stop device indicated as a whole by the numeral 83 which is mounted for longitudinal adjustment upon a rod 84 and which rod is preferably of rectangular form in cross section, and this rod is mounted in bearings 85 projecting laterally from the wall 6 of the supporting frame at the side of said frame opposite that at which the control lever and operating mechanism are located. This rod 84 has a free limited longitudinal movement in said bearings. Said stop device which is adjustable along the rod 84 consists of a sleeve 86 slidable upon the rod and adapted to be held in adjusted position by means of an angle lever 81, this sleeve carrying said angle lever 81 pivotally mounted thereon between upwardly extending ears on said sleeve with its horizontal arm provided witha pin 88 extending downwardly through an opening in the sleeve to engage the upper side of the rod 84 whenever said lever 81 is swung against the action of a coiled spring 88 interposed between said horizontal arm and' said sleeve.

As shown in Figs. 4 and 10, the sleeve'86 is provided with an outwardly extending integral handle 90 which extends outwardly through the longitudinal slot in the wall of the casing -2 and over a scale 8| extending the full length of said slot, and there is an upper pivotally supported handle 82 extending parallel with the handle 80 and carrying a pin 93 on its inner end to project through an opening in the upper side of the sleeve and frictionally engage the upper side of the rod 84, a coiled spring 94 being interposed between the outer ends of said handles-to normally hold said pin 93 in firm frictional engagement with the rod 84. Therefore by pressing the outer ends of the two handles toward each other, the pin 93 is lifted out of engagement with the rod 84 and the sleeve 88 may then be shifted to any desired position along the rod 84, the scale 8| indicating the position of the sliding sleeve 86 which through the medium of the upwardly extending'arm of the right angle lever 81 determines the length of the tape which is to be fed out and cut off, said upwardly extending arm of said lever 81 having a slot therein through which a flexible steel tape or strip 95 extends, said steel tape being adapted to be wound upon a pulley 86 in one direction by means of a coiled spring 81 within the pulley for turning it in one direction and winding up the tape. From the pulley 86 this steel tape 85 extends in a straighthorizontal run extending parallel with the rod 84 with the forward end of the tape extending beneath and partly around an idler wheel 98, with this end of said steel tape secured to the projecting hub of a large gear 88, to be wound thereon which gear is mounted for rotation upon a stud I00, said stud projecting outwardly from the adjacent wall 6 of the supporting frame, and this large gear 98 is in permanent mesh with a pinion IOI of extended length mounted for sliding movement upon the outer end of the shaft of the lower feed roll l2.

To drive the large gear 89 and thereby wind the steel tape 85 about its hub against the action of the coiled spring 81 and produce a longitudinal traveling movement of the steel tape between the winding roll 86 and the idler roll 88, a clutch member I02 is pinned to the shaft of the lower driving roll [2 in opposed relation to the small gear lnl, said clutch member and gear being formed with teeth adapted to intermesh when the small gear is slid longitudinally toward the clutch member. When so intermeshed, power is transmitted to the small gear l0l andfrom this gear to the large gear 88 to wind the steel tapeabout its hub, and to disconnect the small gear from the clutch member, said small gear is formed with a circumferential groove to receive the end of a fork I03 which is secured to the outer end of a longitudinally shiftable shaft I04, which is mounted within a long bearing upon the adjacent side wall 6 of the supporting frame with a coiled spring I interposed between the wall and a head I06 on the inner end of this shaft. A cam lever I 01 is pivoted intermediate its ends upon a stud I08 projecting inwardly from the wall 8 and the lever I0! is adapted to engage the head I06 of the shaft I04 at its upper end. The long lower end portion of said lever I01 extends downwardly with its lower end adjacent the shaft 62 and projecting from the outer side of said lever is a lug I09 having a cam surface or inclined edge portion adapted to be engaged by an arm I I0 secured in any suitable manner to the shaft 31 upon which the control lever 36 and the lever dog 43 are mounted. Therefore when the -shaft 31 is rotated by an upward movement of the lever dog 43 upon release thereof at the lower end of the downward movement of the control lever 30, the arm IIO on said shaft 31 will be brought into engagement with the inclined or cam surface of the projection I09 on the lever I01 and said lever will be swung upon its pivot to force the shifting shaft I04 longitudinally against the action of the spring I05 and thus move the pinion IOI out of engagement with the clutch member I02 and thus disconnect said pinion from driving engagement with the clutch member to stop the winding of the steel tape 95 about the hub of the large gear 99. Therefore the longitudinal movement of the steel tape is stopped and started in timed relation to the stopping and starting of the motor 34 and also in timed relation to the operation of the feed rolls I2 and I3 for feeding the tape, and also in timed relation to the cutting off movement of the knife 2I to sever that portion of the gummed tape which has been fed out and the length of which portion is determined by the setting of the stop device 83 along the rod,

84, said steel tape 95 being threaded through the slot in the upwardly extending arm of the bell crank lever 87 and secured to this steel tape 95 in any suitable manner is a head II I. Said head II I is adapted to engage a loop or eye II2a on one end of a rod II2 so that as said steel tape is moved longitudinally by winding it upon the hub of the large gear 99, said head II I will move away from said eye II2a, and come into engagement with the upwardly extending arm of the bell crank 81, tilting the bell crank to bring its pin 88 into firm engagement with the rod 84 and through further movement of the tape 95, will move said rod 84 longitudinally in its bearings 85 a distance limited by stop collars 85a on said rod, the forward end of said rod being brought by such longitudinal movement, into engagement with an upwardly extending arm II3 on a block I I4 which is pinned at one end to the shaft 48 upon the opposite end of which the pointed lever 41 is secured. The block H4 is thus rocked downwardly against the action of a coiled spring II5 interposed between its lower side and the base I of the machine, thus rocking the shaft 48 and its pointed lever 41 in a direction to swing the latch lever 50 and also the latch dog 53 and release the lever dog 43 so that said lever dog will fly up quickly, operating the lever pawl 69 and-the slide 25 to sever the tape and operate the switch I9 to stop the motor 34. Therefore the lengths of gummed tape 4 which are to be fed out and cut off, are accurately determined in length by the length of the movement of the steel tape 95 which is determined by the head III coming into contact with the stop device 83 which moves the rod 84 longitudinally to rock the shaft 48 and immediately stop the operation of the machine.

The rod '2 which is provided with'the loop I I2a at its rear end and through which loop said tape 95 freely passes, is connected at its forward end to a bell crank brake lever IIG which is pivotally supportedintermediate its* ends upon a supporting stud ill with its short arm provided with a brake pad H8 in opposed relation to the outer end of the pinion IOI, and therefore, when said pinion is released from clutching engagement with the clutch member I02 as hereinbefore described, and the transmission of motion from the shaft of the feed roll I2 to the large gear 99 is stopped, any further continuance of the rotation of said gear and pinion is resisted by said brake II8 when the end of the measured distance of travel of the steel tape 95 is reached and the gear 99 then released to permit the spring 91 to wind it back upon the winding pulley 96 and from the hub of the gear 99, this return travel of the tape 95 will move the head II I back into contact with said loop 211 on the rod II2 exterting a pull by reason of such travel, upon the brake'lever I I0 to bring the brake pad II8 into braking engagement with the pinion IOI, thus resisting the travel of the steel tape caused by the spring 91 and prevent any slack being formed in said tape. a

As before described, when the shaft 62 is ro tated by hand, the cam 6| will operate through the pin 59 to hold the latch or dog 53 in inoperative position, this being for the purpose. of preventing the control lever 38 from being locked at the lower end of its stroke should the control lever not be released immediately upon its reaching the lower end of its stroke; and when it is desired to continuously feed a strip of gummed tape of uncertain length or of a length greater than that provided for by the operation of the measuring means hereinbefore described, the operator will press inwardly upon the shaft 62 to move the pin 68 into engagement with the cam surface 61 and he will then turn the shaft, thus moving the shaft endwise to move a collar II9 fixed on the shaft 62 into engagement with the lower end of theshifting lever I01, thus pre venting said lever from swinging to permit the pinion IOI to engage its driving clutch member I02, and therefore the measuring mechanism including the steel tape, travel of which is effected by rotation of the gear 99, will be prevented from operating. However, the feed rolls I2 and I3 will be operated as usual by the motor to feed out the gummed tape, as long as the control lever is held at the downward end of its stroke.

When the desired length of gummed tape has been fed out, the operator will release said control lever but such movement will not release the latch lever 50 from engagement with the lever dog 43 and permit said dog to fly upwardly to operate the lever pawl 69 to effect a downward movement of the slide 25 and cutoff the tape or to operate the switch and stop the motor. Therefore a double pawl I20 is pivotally supported under the urge of its spring 46, saidpin I2I 'will 7 8" tilt the said double pawl, bringing its short arm into engagement with the upper end of the latch 50 and release said latch from engagement with said lever dog 43, permitting it to fly up and turn the lever pawl 69 into engagement with the pin 29 on the knife slide 25, operating the knife to quickly and automatically sever the extended length of gummed tape which has been fed out.

-With the elements of the machine in the position shown in Figs. 1 and 2, the machine is at rest and ready to be operated by pressing downwardly upon the control lever 36. The first portion of the downward swinging movement of this control lever, brings the slide 39 into engagement with the forward end of the lever dog 43, thus swinging said dog downwardly and rotating the shaft 31 to which the dog is secured. This rotation of the shaft-31 brings the clamp member 8| on said shaft into engagement with the projection 82 on the casing of the electric motor 34 and said motor is swung upwardly thereby to bring the friction wheel 32 on the outer end of its shaft into frictional engagement with the large friction pulley 3| mounted upon the shaft of the lowerfeed roll l2. In timed relation to this engagement of the friction wheels to transmit motion from the motor shaft to the lower feed roll, the lever dog 43 by its downward movement, operates the control switch lever 80 to start the motor.

This downward swing of the control lever 33 disengages the brake shoe l2 from engagement with the periphery of the large pulley 3| to permit free rotation of said pulley when driven by its engagement with the pulley 32, which is driven by the motor and in timed relation to the bringing of the friction pulleys into contact, the downward movement of the lever dog 43 operates through the connecting rod'lB to permit the upper feed roll l3 to swing downwardly and thereby engageits gear 30 with a like gear on the shaft of the lower feed roll I2 so that as soon as the motor starts to rotate the lower feed roll, motion will be transmitted to the upper feed roll and the feeding of the gummed tape 4 forwardly, will begin.

This forward feeding of the gummed tape is quite rapid due to the rapid rotation of the'feed rolls and therefore if the measuring mechanism be set at this time tofeed out comparatively short lengths of gummed tape, the mechanism controlling the operation of the release of the lever dog 43 and the latch lever 50 by means of the operation of swinging movement of the lever 41, may operate so rapidly that the dog 53 will be released from engagement with the pin 56 on the control lever and reengaged therewith before the lever 36 has started its upward swing, in which case the control lever would be locked at the lower end of its stroke. To prevent this the operator may turn the shaft 62 to bring its cam 6| into engagement with the pin 55 which in turn will hold the dog 53 out of operative position so that the control lever will be immediately returned to the upper end of "its swinging movement for a second operation.

If the operator desires to feed out a length of gummed tape of a length greater than that provided for by the measuring mechanism, he will move the shaft 62 longitudinally to engage the pin 68 with the cam. surface 61 and then by turning the shaft 62 will move the shaft longitudinally and bring the collar I IS on said shaft into engagement with the lower end of the shif ing lever I01, thus holding said lever in a position to hold the pinion IOI out of clutch engagement with the clutch I02 and thus prevent the transmission of motion from the lower roll shaft to the large gear 99 for winding the steel tape 35. Therefore the measuring mechanism is thus made inoperative and as long as the operator holds the control lever 36 down, the motor will continue to drive the feed rolls l2 and I3 and feed out gummed tape. Immediately upon his release of the control lever, the upward movement thereof will release the latch lever 50 from engagement with the lever dog 43' and said dog will come into contact with the lever pawl 69 and operate the knife to automatically cut off the length of gummed tape which has been fed out.

In the operation of the control mechanism, the lever dog 43 is swung downwardly by its engagement with the slide 39 carried by the control lever 36 but is released from such engagement in timed relation to the downward movement of the control lever, by the engagement of the pointed lever 41 with one side of the notch 49 in said slide, moving said slide longitudinally a sufiicient distance to disconnect it from the lever dog 43. However this downward movement of the control lever has at this time brought the end of the lever dog 43 into engagement with the latch lever 50 which immediately operates to hold said dog in its lowered position and at the same time this downward movement of the latch lever has brought its pin 56 into engagement with the dog 53 so that both said dog and said lever dog 43 is held against upward movement until the pointed lever 41 is swung by rotation of its shaft 48 which rotation is caused by the longitudinal movement of the rod 84 effected by the travel of the tape 95, which travel brings the head IH secured thereto, into engagement with the stop device 83 mounted thereon, thus swinging the pointed lever to operate the latch lever 50 and the dog 53 to release both the control lever 36 and thelever dog 43, permitting them to return to rest position and stopping the operation of the motor and the feed rolls.

With this described arrangement and operation of elements, the machine is operated by a single hand control lever and the mechanism controlled thereby is automatically operative to feed out short measured lengths of gummed tape or indefinite lengths depending upon the setting of the hand operated shaft 62, and all of the parts of the machine are arranged to operate in oer-'- taintimed relation so that all the operator needs to do is to compress the control lever and the machine will operate to feed out short continuous or measured lengths of gummed tape and cut it off at the proper time.

Obviously changes may be made in the particular construction of operating mechanism and in the measuring and feeding mechanism without departing from the spirit of the invention which consists in the feeding out of lengths of gummed tape automatically and automatically cut off these lengths at the proper time; therefore I do not wish to limit myself to the particular construction shown and described.
