parts, and Fig. 15 being a section on the line 15-45 of Fig. 13. I

Referring more particularly to the drawings, and first to Figs. 1 to 3, the mechanism as a whole is preferably mounted upon a platform or base 1 upon which are set the spaced side frames 2, 2 floor 3 and by the tie rods 4, 4 near the forward or moistening and delivery end of the machine. 2

Said tie rods are adapted to serve as supports for the moistening means, illustrated as a reservoir or tank 5 from which projects an inverted brush moistener 6. The moistening means, including reservoir and brush, as shown, is readily bodily removable, being received upon the tie rods and provided with suitably spaced depending bosses 7, 7'for receiving one tie rod 4 between them, to position and retain the reservoir.

The tape supply, usually in roll form, is adapted to be supported at the rear end of the machine, the end opposite the moistening end. For this purpose We have provided the rearwardly and upwardly-extendingtape bracketS preferably secured to the base 1, or it may be positioned independently thereof. This bracket carries a lateral stud 9 (see also Fig. 12) adapted to support rotatably a roll of gummed paper or other tape or strip material T to be dispensed, the stud 9 being positioned at a proper height to support for free movement'the largest diameter roll which it is desired to use.

In connection with said bracket and stud We have provided novel means for retaining the tape roll in feeding position and at the same time controlling the tension on the tape and preventi1 1g back lash.v As illustrated, said means comprises a single element including a weighted member 10 which may have its under face properly concaved' to conform generally to the periphery of the tape roll upon which it rests. Integral with or secured to the weight 10 is a depending arm or fork 11 formed with a vertical slot 12 open at its bottom 'to permit said member to be passed interconnected as by the feed downwardly over the stud 9. Projecting lat orally from the weight is a plate orexten- SlOIl 13 havlng series of slots or opemngs 14 wherebythe plate may be passed downwardly over the upper portion or finger 15 of the tape brapket 8. If desired, and as illustrated,

', the transverse member or plate 13 and the depending member or fork 11 may be formed of 'a single strip bent at right angles and attached to the weight. By reason of the plurality of'the openings 14, the described 'po-..

sitioning and regulating element is adapted to cooperate with tape rolls of various widths. Claims directed to this strip regulating and positioning means are contained is-advanced to the feed floor 3, passing first in thecopending divisional application of T. R. Gautier, Serial No. 363,083, filed May 14, 1929.

:The tape T coming from the supply or roll beneath a guide roll 16 rotatably supported between the side-frames or the upward extensions thereof or stands 17, 17, and is adapted to be fed forwardly across the feed floor stituting a portion of the tape severing means, and thence is guided forwardly across the reservoir and over the brush moistener to.

the delivery point. Y

' Thetape is guided in proper moistenin'g relation to the brush as by means of the plate orpr'es'ser2O resting freely upon the tapeas it passes over the brush. Said plate or presser 20 is arranged for vertical pivotal or yielding' movement and; as illustrated, is readily v bodily removable fromthe machine together with the weighted member 18. For this purpose the-plate is formed with a rearward extension 21 received between and pivotally connected, as at.22,'to upright lugs 23, 23,

\ upon the member 18 (see particularly Figs. 1

and 3). The forward face of the weighted member 18, when the latter is in assembled position, rests, or is forced by the feed, against the rear face of thefixed blade 19, and

- the rearward extension 21 of the plate overlies said blade.

Both the plate 20 and the member 18 are thus retained in proper position, while enabling them both to be removed together by merely grasping and lifting either of them.

For feeding the tape there is provided a feed wheel or roll 25 which, as illustrated, need not be of the full .Width of the tape. Thisfeed roll 25 (see particularly Fig. 2) is faston a cross shaft 26 journalled'at its'opposite ends in bearings 27, 27 on the respective side frames-and held against longitudinal shifting movement asby the collars 28, 28.

Said feed roll may be actuated in any suitable manner, as by a pulley 011 the shaft 26, but is preferably arranged for direct motor drive fronfian electric motor 30, herein mounted upon the platform 1, but which may be otherwise supported. Fixed on the shaft 26, herein between the side frames 2, 2, is a worm gear 32 meshing with a worm 31 formed, on or directly connected with the rotor of the motor 30. The feed floor 3 is formed with an opening 33 (see Figs. 1 and 3) into which the feed roll 25 projects to engage with its periphery the under face of the tape. 1 v I The remaining portion ofthe feed mechanism which cooperates with the driven feed roll 25 to feed the tape, and also the entire feed control mechanism, in accordance with the present form of the invention, is mounted on or carried by a control head or frame. As best seen in F ig. 6, said head comprises a main frame or carrier 35 preferably formed as an integral element or casting. Said frame together with the parts carried by it will hereinafter be referred to as the control head. As best seen in Figs. 1, 4 and 6, this frame or carrier 35 comprises a main or carrier portion 36 of substantially the Width of the machine and provided near its rear part with downwardly extending lugs or cars 37 formed with bearings 38, 38 for pivotally supporting the entire control head, as upon the stud shaft 39 (see Figs. 1, 3 and 5) extending between the stands 17, 17 on the side frames. The guide roll 16 previously mentioned is also mpunted on said stud shaft 39.

Forwardly of the point of pivotal support 'of the control head the carrier frame35 is provided at its opposite sides with bearings 40 for rotatably' supporting a cross shaft 41 to which is fixed the upper feed roll 42, in position to cooperate with the lower and driven feed roll 25 so as to feed the tape between them when the u per feed roll ongages the upper face of t 1e tape and is free to rotate; The control head includes a forwardly extending operating lever 43 which .may be of the general form seen in Fig. 4,

having a finger piece 44 at its forward end. Said lever 43 may be provided with means such as the button 45 for connection with a pedal or other foot control means.

The operating lever 43 and entire control head is normall maintained in raised position, substantia ly as shown in Fig. 1, as by means'of a sufficiently strong spring 46 through which extends a guide rod 47 secured at its upper end to the projection 48 on the operating lever or other portion of the control head and slidably guided at its lower end in a boss 49 on the adjacent side frame 2. This spring bears at its lower end against the upper face of said boss and at its upper end against a thumb screw or adjustable collar 50 threaded upon the guide rod 47 From pressure on the lever 43, compressing the ering operation, a lost-motion or similar conspring 46, the upper feed roll 42 is brought down into position to engage and feed the tape in cooperation with the lower and driven feed roll 25. The upper feed roll is rotated only by reason of its co-action with the lower, and driven feed roll, through the tape engaged between them. The tape'is accordingly fed so long as the two feed rolls remain in tape engaging position and the upper feed roll is left free to rotate.

Upon release of the depressed operating lever, the control head is returned to its inoperative or raised position and the tape is severed, as by means of the pivoted blade 52 supported at one end upon one of the side frames and cooperating in a shearing manher with the fixed blade 19 previously mentioned. The pivoted blade is operatively connected at its free end with the operating lever as by means of theadjustablerod 53, sufficient movement of said rod relative both to the operating lever and to the pivoted blade being afforded in its connections therewith to permit it to conform to the slightly arcuate movement of theoperating lever. The pivoted blade is disposed normally to liebelow the path of the tape and toreturn to such position immediately upon completion of the sevnection between the blade and the rod 53 being provided such as to permit the blade to upward movement by suitable means such as that seen in Fig. 5, the carrier or casting being formed at one or both sides with a boss or a stop 55 to contact with the forward face of the stand 17 on the corresponding side frame.

The construction and arrangement of the control head, as herein illustrated, is such that the same frame or casting is adapted for use with several different control mechanisms, to adapt the machine for control in a like number of different ways, according to the conditions under which it is to be utilized. For example, in many nstances it is merely desirable that the machine shall feed and moisten tape under power operation, the operating period and consequent length of tape fed to be determined by the length of time the operating lever is held depressed. In such case, with the described mechanism, the operator depresses'the lever and control head, the tape is fed out and moistened, and the operator releases the lever, efi'ecting stoppage of feed and causing tape severance, when hejudges that the desired length has been delivered. For accomplishing this result the machine need include only the mechanism described to this point, the control head carrying, in addition to its spring and its blade-operating connections,

only the crosss'haft 26 and upper feed roll 42 thereon. The machine so equipped may be referred to as type A.

In other instances it is desirable that the operator be able to determine accurately at any instant the length of tape which has been fed, rather than leaving this determination to his judgment and operating skill as in type A. To afiord such measured operation under manual control, in accordance with the invention the control head .is supplied in ad dition with suitable measuring or indicating mechanism and when so equipped may be referred to as type B.

heferring to Figs. 1 to 6, and more particularly to Figs. 2, 3, and 4, the control head is provided in type B with an additional cross shaft 57 journalled at its opposite ends in the sides of the'control head, preferably somewhat above the axis of the upper feed roll 12, as in the bearings indicated at 58' in Fig. 6. Fixed on said shaft 57 is a worm or spiral 59 and also a pinion 60 meshing with a similar pinion 61 fixed on the shaft ll of the upper feedrol] 42. The spiral or worm is thus rotated by and proportionately to the upper-feed roll 42, and consequently in proportion to the length of tape fed.

, To the rear of the shaft 57 the control head. frame or carrier 35 is drilled, as at 62, Fig. 6, to receive the rod 63 upon which is'rockably and slidably supported a linger 64 (see particularly Figs. 1, 3 and 4;) having depending from its forward end a partial nut 65 adapted to mesh with the worm 59 at certain times. Said slidable and rockablc finger 64 has fixed to its rear portion a leaf spring 66 the lower portion of which engages a stationary rod 67 extending between the stands 17, 17 on the machine side frames. This spring tends to urge the nut 65 downwardly and toward the spiral 59.

When the control headis in raised or normal and lnoperative position, as in Fig. 1,

the finger 64 and partial nut 65 carried thereby are raised away from the spiral so that said nut is out of engagement therewith. This is herein effected by reason of a downwardly projecting'nose 68 on the finger 64, the rear face of which nose is engageable in a camming manner with the stationary rod. 67, but at the side thereof opposite that contacted by the spring 66. It will be understood that as the control head is depressed all parts thereon, including the finger 64 move bodily about the control head pivot 3. The pivot 63 of the finger 6-1 is thus moved counter-clockwise or to the left in Figs. 1 and 3, tending to carry the 110550 68 away from the stationary rod 67, sufficiently to permit the spring 66 to rock the finger and lifting the nut away from the spiral and back into the normal or inoperative position of Fig. 1.

i In this-manner the nut, normally out of engagement with the spiral, is brought into operative engagement with it for actuation thereby simultaneously with the bringing of the upper feed roll into tape feedin relation with the driven feed roll 25. Rotation of the spiral will thus cause the nut to be traversed, its supporting finger 64 sliding along the rod 63. 5

Projecting upwardly from the traversable nut-65 is a pin 69 received in an arcuate slot 70 formed in an indicator or pointer 71 swivelled on the upper face of the control head, as at 7 2, and codperating with a scale or index 73 marked in inches or other suitable units to indicate the length of tape fed. By watching the indicator 71, which is moved pro portionately to the length of tape fed by the mechanism above described, the operator may \i and the served portion of tape is sev tell at any timethe length whichhas been:

delivered and moistened. hen the ihdi cator shows that the desired length has been reached, the operator releases the lever,

whereupon the control head is,returned to the position of Fig. 1, the tape feed is interruptedby movement of the upper feed roll away from the driven feed roll 25,

eredL With, the return of the control head to'raised positioxh the traversable half-nut v is also lifted out'of engagement with the spiral to permit it to shift back transversely of the machine to its initial or zero position. Such return 'of the nut 65 is effected as by means of' the coil spring 74 which encircles the rod 63 on which thenut is carried aii d bears at its opposite ends against the finger 6% and the side of the control head, forcing the finger back against a stop or collar on saidrod. -'It will thus beiseen'that the control head is constructed and arranged for actuation under manual length. For this purpose the machine may additidnally be equipped with novel feed-stop mechanism, for the reception of" which the -control head is particularly adapted, in acmaaese cordance with the present invention. This latter equipment may be referred to as yp 0 Referring still to Figs. 1 to 6 and first more particularly to Figs. 4 and 6, the control head is provided with an additional bar bar slidably but non-rotatably received in openings at the opposite sides of the control head, one of which is seen at 81 in Fig. 6, illustrated as a square opening to cooperate with a like formed section of said slidable bar to prevent rotation thereof. I-he slidable bar carries a stop 82, see also Figs.

1, 2 and 3, in position to be engaged by the nut-carrying finger 64 and is threaded at one end, herein the left as seen in Fig. 2 and 4,. to receive an adjustable thumb-nut83. The flange of this adjustable nut projects into a groove 84 formed in the head. 85 of a plunger 86, seen in detail in Fig. 8. Said plunger. is slidable in a housing 87, being normally urged outwardly as by a coil spring 88 surrounding a portion of the plunger of reduced diameter and bearing intermediate the shoulder 90 on the plunger and the inner end of the housing. Outward movement ofthe plunger is limited as by means of a stop 91 thereon working in a slot 92 in the plunger -housing. At its inner end the plunger is l formed with a nose 93 and an inclined cam portion 94.

Said plunger cooperates with feed-stop mechanism preferably carried by the. control head and which may be best described with reference to the Figs. 9 to 11 but which is also seen in Figs. 1 to 4. Uponthe cross shaft 41 and coaxial with the upper feed roll 42 is fixed a ratchet wheel 95; see particularly Figs. 2 and 4. Above said ratchet wheel is a spring-pressed detent or dog 96, seen in detail in Fig. 7, and which is guided for sliding movement toward and away from the ratchet wheel in a housing'97 removably mounted on the control head. The detent is urged downwardly or outwardly of the housing as by the coil spring 98 bearing intermediate thedeteht and the upper wall of the housing. Projecting laterally from the detent and toward the left as viewed in Figs. 2 and 7 is a pin 99 extending through a slot 100 the housing and whereby the detent may be held up against its spring pressure or be permitted to drop.

.Said pin 99, as best seen in said Figs. 9 to 11, rests upon one endof arockable latch 101 pivotally supported as at 102 upon the adjacent wall of the control head. At the opposite side of its pivot point this latch 1s formed with a shoulder 103 adapted to be engaged by a nib 104 of a trigger 105 pivoted at 106 upon the same wall of the control head. Said trigger has a rearwardly projecting finger 107 which rests upon the nose 93 of the spring-pressed plunger 86 previously described; I

1 occupy during non-feeding of the machine,

and also during feeding, up to the point at which the feed is to be terminated. Re-

'-..ferring to said Fig. 9, it will be understood that if the trigger finger 107 is lifted the nib 104 will be caused to slide off from the shoulder 103 into the position shown in Fig. 11, in so doing first lifting the pin 99 slightly and still further compressing its spring 98, and then permitting said spring to de press the detent 96 into engagement with the ratchet wheel 95. The detent and ratchet wheel are so arranged that immediately upon their inter-engagement they hold the upper feed roll 42 from tape feeding movement, that is, as herein illustrated, from movement in a clockwise direction as viewed in Figs. 1 and 3. The lower or driven feed roll 25 at such time may continue its rotation but merely slips past the adjacent face of the tape without feeding it, due to the stationary positionof the upper feed roll. Thus the motor may run continuously.

Said automatic feed-stop mechanism may be set to afford any desired length of tape by simply adjusting the position of the stop 82. This may readily be done by moving the pointer to the desired length-indication on thescale and then adjusting the stop 82, by sliding its bar through themedium of the thumb nut 83, so that the nut-carrying finger 64 will just come up into engagement with the stop 82' when the pointer is over said indication. To facilitate this. adjustment the rod 63 upon which the nut carrying finger 64 is mounted may be made slidable in the control .head and be provided at one end, the right as viewed in Figs. 2 and 4, with a head 108 which may be grasped to draw the rod outwardly, thus shifting the. finger 64, the nut 65 and the pointer 71 to the desired position.

Having set the feed-stop mechanism, the operator may start thefeeding operation in the ,usual manner, by depressing the operating lever and the control head to which it is attached, bringing the upper feed roll down into tape feeding relation with the lower feed roll, and also effecting engagement .of the traversable nut with its operating spiral or worm. The operator thereafter need not consult the feed-length indicating mechanism to ascertain when the predetermined length of tape has-been delivered, as the feed will be stopped automatically at the proper point. As the traversable-nut-carrying finger 64 comes up against the stop 82 it shifts the lat; ter and the bar 80 to the right as viewed in Fig. 4. Through the connectingthumb nut 83 on said bar the plunger 86 is thus caused to move inwardly against its spring, engaging the plunger cam 94 beneath the finger 107. of the trigger 105, thus tripping the latter and permitting the detent 96 to be forced down into engagement with the ratchet wheel 95 thereby to stop the feed in the manner already described.

Means is also provided whereby the automatic feed-stop mechanism, and particularly the detent 96 and associated parts, are returned to their normal position after having acted to stop the feeding and upon subsequent release of the operating lever for return to its normal or raised position. Referring first to Fig. 9, it Will be understood that since the plunger 86, the trigger 105, thelatch 101, and the detent 96 are all carried by the control head, they all move with the latter when it is depressed, the pivot points 102 and 106 of the latch and trigger travelling in a short are about the stud shaft 39, which is the pivot point for the entire control head. The latch 101, in addition to its parts already men'- tioned, is provided with a rearwardly extending nose 109 having a rear face normally in engagement with the stationary rod 67 extending between the machine'side frames, this engagement resulting from downward pressure of the spring 98 in the detent housing, which, through contact of the pin 99 with the latch 101, tends to pivot said latch in a manner to move the nose 109 thereof toward the stationary rod 67 As illustrated in Fig. 9 the control head and operating lever are in their inoperative or raised position.

In Fig. 10 the same parts are shown in the depressed or operating position of the control head but with the detent still in raised position, permitting the tape to feed. In said F ig. 10 it will be noted that the several parts have revolved about the point 39 in a counter clockwise direction so that the nose 109 of the latch 101 is carried out of engagement with the stationary rod 67. The detent spring cannot move this latch nose further to the right in the figure and back into engagement with said stationary rod 67 so long as the nib 104 of the trigger 105 rests upon the latch shoulder 103; 7

Assume now that the desired tape length has been fed and this trigger has been tripped, by actuation of the stop 82 and plunger 86, to stop the feed. The trigger nib 104 rides off .the latch and the detent'96 is permitted to be forced down by its spring. 'As the detent comes down the latch is rocked slightly upon its pivot in a clockwise direction, bringing its nose 109 again into engagement with the stationary rod 67. This condition of the parts is that illustrated in Fig. 11, wherein the con trol head and operating lever are still 'depressed. Upon release of the opera-ting lever, the control head and the parts illustrated in Fig. 11, with the single exception of the stationary rod 67 return bodily in an arcuate path about the center 89 and ma clockwise direction, into their former position, as shown in g- 9, This bodi y sm' nt 01" th P rts wheel and returning it to its raised position.

If desired, a small spring (not necessary to be shown) may be provided to assist in the return rocking movement of the trigger 105 on its axis 106, promptly to bring it from its position as in Fig. 11 to its original position as in Fig. 9.

All of the parts are thus brought back again to their normal position in preparation v for the feeding ofv succeeding lengths of tape under automatic control.

In Figs. 13 to 15 we have illustrated a modified form of mechanism also embodying our invention. In said figures parts not otherwise referred to will preferably be the same as in figures previously described. The mechanism of saidF igs. 13 'to 15 exemplifies one means whereby the rotary spiral or worm '59 or other rotary or measuring device with "which the index or pointer cooperates is caused to return always to its same or original angular position, its starting position, after each actuation.

For this purpose we have provided a stud 110 upon one side frame 2, herein the left side, this stud serving as a hinge pin for an arm 111. Near its upper end said arm/111,

carries a lateral fpin 112 on which is journalled one end 0 a link 113, the other end of which is journalled upon the adjacent proe jecting. end of theupper feed roll shaft'.41.

The arm 111 is operatively connected with the control head operating lever 43..

Said arm 111 is also provided at its upper end with a lateral, oflset forked portion 114,

. '(see particularly Fig. 15) across which extendsa levis pin 115, the latter servingas a pivotal support for -a worm returning element or bumper arm 116. The arm 116 1s formed with a second arm portion or finger 117 to the end of whichis secured a helical spring 118 having its opposite end attached to a short projecting portion 119, formed in"- tegrally with the arm 111. In the inactive or normal posit-ion of said parts, the spring 118 holdsthe bumper arm 116 upwardly and against a burnished spot or stop 1-20 on the arm 111. At such time the operating handle 43 is raised as in Fig. 13, and the forward face 121 of the bumper arm 116 is in contact with a crank pin 122 projecting laterally and outwardly from a disk 123 attached to the outer'end of a sleeve 124 journalled in the adjacent portion of the. control head frame.-

At itsinner end the sleeve 124 is formed with a diametral tongue 125 seating in a corresponding slot 126 in the adjacent end of the spiral or worm 59, thus connecting the latter, the sleeve 124, the disk 123 and the crank pin 122 for rotation in unison.

The operation of the described parts will be readily understood and particularly by reference to Fig. 14, which illustrates the parts in a position such as occupied during feeding operation of the machine. When the control head is depressed to institute a feeding operation the link 113, being pivoted on its control head at its upper end, is moved down, forcing the arm 111 to be rocked counter-clockwise as viewed in Figs. 13 and 14, further tensioning the spring l18 and at the same time carrying the bumper arm 116 as a whole rearwardly and downwardly out of the path of the crank pin 122, substantially into the position indicated in Fig. 114. This crank pin, disk 123 and the measuring spiral 59 are thus free to rotate; When pressure on the operating handle isreleased to stop the feed,tl1e arm 111 is snapped back into its original position,'by reason of its connection with the operating handle. This also brings the forward face 121 of the bumper arm 116 into engagement with the crank pin 122, in whatever position circumferentially of the axis of the disk 123 of the-spiral 59 it may have been left. I Engagement of the bumper arm with said crank pin, further assisted by the action of the tensioned spring 118, will move the crank pin mom or the other rotary direction, dependently upon the position in which-it is first engaged, back into its original or starting position as shownin Fig. 13, that beingthe farthest point forward or to the right, in the figures, to which the crank pin may be moved. The crank pin is so arranged with respect to the spiral that when the former is in its indicated starting position the spiral will be in its desired starting po sition, so'that the engaging portion of the movable pointer will immediately cooperatewith the thread of the spiral, eliminating all possible lost-motion or inaccuracy in measuring.
