Referring to Figs. 1 and 2 of the drawings the structure therein illustrated comprises a base or support 1 having journals 2 for rotatably supporting a shaft 3 which supports a roll 4L of strip material such as paper tape 5, Fig. 7, Which is provided with weakened portions or transverse slits 6 at spaced apart intervals and which is further provided with gummed portions 7 adjacent the slits.

Again referring to Fig. 1, the support 1 is provided With a top or cover member 8 which may be permanent or removable and which forms a passage 9 with a sheet metal strip 10 through which passage the end of strip 5 is made to pass. 0

As shown in Figs. 2 and 3, the cover member 8 may be hinged as at 11 and secured by a wing nut 12 to the support or base 1, thereby rendering the cover member removable for the purpose of providing access to the interior of the apparatus.

Referring to Fig. 3 a shaft 14 is rotatably journalled in the housing support 1 in journals or bushings 15. Secured to the shaft 111 is a spiral spring 16, one end of which is fastened to a spring casing 17. A gear wheel 18 is rotatably journalled on the shaft 14 and is provided with a clutch element 19, Fig. Q, which is adapted to cooperate with a compleinentary shaped clutch member 20. The

member is operatively connected to rotate with a ratchet wheel 21 that is fixed to rotate with the spring housing 17 so that when the clutch 19-20 is engaged, the spring housing 17 will be the driving member for gear wheel 18.

The gear 18 through an idler gear 18 actuates a gear wheel 23 that is fixed to rotate with a shaft 24 Fig. 3 journalled in bearings 25 which are vertically movable in 'depending bosses or lugs 26 formed integrally with the cover member 8. As'shown in Fig. 1, the bosses 26 are provided with slotted openings 27 in which the bearing members 25 are disposed for vertical movement and the bearing members 25 are biased by coil springs 28 in the direction of. the `roller 30 thereby assuringthe proper operatingl contac-t of the rollers 29 andz30 ivitlrstrip 5.

The shaft 25 carries a frictional roller 29 ofrubber orv other yielding material which roller cooperates with a flanged roller 30 to intimately engage the paper strip 5 therebetween. The shaft 24 is further provided with a gear wheel 31 on the end opposite to thegear wheel 23. 'llhcgear 31l rotates with the shaft 24. The teeth ofthe gear wheel 31 are adapted to Vmesh or-interact'Y with the teethof'a gear wheelY 32 which is rotatably mounted on shaft 14 and provided with a clutchiface' 33: thatVr cooperates with a clutch face 34 of a movable clutchk member which is in sliding engagement withv a sleeve element 35 that is rotatable with the shaft 14. Mounted; on the sleeve element 25iislal cam= 36 having airi'ser 37 on.r one sidethereof which cooperates with. a camY follower 38. AnotherV cam element 39 is rotatably mounted onv the sleeve 35 and is provided with a follower 40. The follower 38 is journalled. on a stud carried by an`r arm 41 of a shifting yoke element 42 which is pivotally connected at 43'toa lug 44 projecting upwardly on the baseof the support 1, theyoke member 42 being adapted for pivotal movement inresponse to. the movement of the camfollower 3S-effected by the cam member 36. y

The arms of the yoke member 42 are providedV with trunnion members which slidaably engage the slotted portions 45 and 46 of clutch members 2O and 34 which members are moved to their clutch making and breaking positions by movement of the yoke 42. l .Y

Referring toFigs. 1 and 2, a severing mechanism is mounted in the housing 1 and operates to sever the strip material 5 at intervals by means of the following mechanism'z-A cut-od knife 50 is secured to a pair of parallel bars-51 which are pivotally mounted on a iiXed shaft 52 to render the knife element vertically movable into a notched or slotted portion 53 of the cover member 8 and' through a slotted portion/54 of the partition member 10, the movement of the knife 50 being across the strip material 5 which is severed thereby. The knife 50 is provided with a tongue or pilot member 55 for a purpose to be hereinafter stated.

Secured to the knife 50 is an angle bar 57, the base of which constitutes a seat for a helical spring 58 that rests upon a lug 59 formed on the housing support 1. The knife 50 is normally biased to the upper or cut-off position shown in Fig. 4 by the coil spring 58 but is held in its lower position as illustrated in Fig. 1 by the paper strip 5 and by a latch bar 60. The latter is provided with slotted openings 61 in engagement with pins 62 projecting from an extended portion of the housing member' andv by means of the slottedengagementwith pins 62 the latch bar is rendered movable longitudinally. The bar 60 is' biased, by a coil spring 63 that is fastenedV to one of the pins 62 and to a pin 64 ine the manner illustrated in Fig. 1. The barV 60- is` further provided with al shoulder portionA 65 having a tapered` edge 66, the shoulder being adapted to engage the knife 50 in the manner shown in Fig. 1. Theother end of the bar 60 is provided with a beveled edge 67 for engaging a pawl 68 that is adapted to lit into-a notch 69 of the cam 36, Fig. 6. The pin element 64 of the bar 60 is adapted for engagement by a bell crank lever-69 pivote'd at 70, the lever being actuated by a depending' portion 71 of an arm 72 that is provided* with an extension 73 which engages the angle bar 57 of the knife as shown in Fig. 4' for the purpose of cooking knife 50 after it has moved to cut-off position. The lever 72 is actuated by the cam 39 through the follower 40 which is carried by an. arm 75 of the lever 72. The ratchet wheel 21 is engaged by a pawl 76 to permit its rotation in one direction only.

The ends of the knife supporting arms 51 are pivotally connected at 77 to a lever 78 carrying a. moistener 79. As'shown in Fig. 4 the arm 78 carrying the moistener is provided with extensions 80 which are engaged by levers 81 that are biasedby spring 82, the object of the spring and lever being to press the moistener 79 against the underside of strip 5in the manner shown in Fig. 4. The moi'stener is adapted to be at all time partially submerged 'in a moistening fluid 83, such as water,.which is provided in a container or well 84, placed on la shoulder portion 85 of thek member 63.

The operation of the combined dispensing, severing and moistening apparatus is briefly vas follows Y Referring to Fig. 7, the strip of rolled tape, as previously explained, is gummed at intervals, as indicated at 7, and provided with weakened transverseportions 6, suchl as perroll 4 and between the friction roll 29 and f the flanged roll 30, and it is then disposed through the passage 9 and projected beyond the dispensing side of the apparatus in the manner shown in Fig. l. I

The eut-olf knife 50 is cocked to the position shown in Fig.v l and the latch bar 6() pressed with the shoulder 65 against the bottoni edge of the knife. rfhe pilot 55 of the knife is supported by the paper strip which acts as an abutment. rlfhe pilot is yieldingly urged against the strip by the action of the coil spring 58.

To operate the device the operator engages the projecting portion of strip 5 and draws it out of the passage 9. In doing so, the roll 29 by virtue of its frictional engagementl With the strip 5, is rotated and in turn rotates the gear Wheel 18 through its gear connection 23. When the mechanism is in the cocked position, as shown in Fig. l, the clutch elements i9 and 2O are in their clutch making position in which position the spring easing 17 is rotated in the direction causing the spring 16 to be Wound up, storing up torsional energy.

Villen the strip 5 has been pulled out to the position Where one of the slits 6 of the strip registers with the pilot 55, the knife will antomatically rise for a distance corresponding to the length of the pilot which is suflicient to release the latch bar 60 and the latter is drawn by spring 63 in the direction of the roll Ll, and in this movement, the lower edge of knife 50 is engaged by the tapered surface 66 of the latch bar and forced upwardly, bringing the cutting edge of the knife into engagement With the strip 5 and evering the same on a line in a plane With the slits 6. The bars 51 carrying the knife in their upward movement, Will cause the member 7 S carrying the moistener to be raised, to bring the moistener into engagement with the end of the strip 5 so that the gummed portions 7 adjacent the cut-off end of t 1e strip will pass over the moistener as the strip is withdrawn from the apparatus.

Simultaneously with the backward inovement of the latch 60, the paivl 68 is engaged by the latch bar and displaced out of contact With notch 69 of the cam 36. This action causes the following sequence of operations rlhe energy stored up in spring i6 will rotate ca ns 36 and 39 causing the siifting yoke l2 to break the clutch element ia-20 and make clutching engagement of the elements 33-34 whereby the gear Whse. 32 is actuated causing the pinion member 3i to rotate. The pinion 3l being fined to rotate the passage 9 for a distance corresponding tov the peripheral movement of the roller 29 which is of such dimension in proportion to its rotary movement effected through the spring release that the strip 5 will project a predetermined distance out of the end of passage 9 as illustrated in Figs. l, 2 and l of the drawings. Y

During the rotation of the sleeve 35 effected by the unvvinding of the spring 16, the follower l0 Will strike the rise of cam 39, thus raising the arm 7 5 of lever 72 and depressing the arm on the opposite side of its pivotal support. By this action the depending longitudinal element 7l of lever 72 engages an arm of the bell crank 69 depressing the latter which produces movement of the latch bar in the direction Which subjects the spring member 63 to tension and the end 7 3 of lever 72 at the same time engages the seat of the angle bar 57 and causes the knife 50 to be lowered to its cocked position at the same time depressing the coil spring 58.

When the knife 50 has fallen beloiv the shoulder of the latch bar, it is out of line with the tape element 5 and it is then that the latter is automatically dispensed through the passage 9 as previously explained.

When the apparatus again assumes its normal position, the pilot 55 of the cut-off knife will yieldingly engage the loiver edge of the strip 5 and the apparatus is set for the removal of the next strip, which is effected in the same manner as described.

It is to be noted that the operation of the severing mechanism is initiated through the slit 6 of the strip material and that the length of strip cut-ofi' by the mechanism is determined by the spacing of the slits in the strip. On account of the fact that the cut-ofi mechanism cooperates with the strip in a manner to be released when the weakened portion or slit of the strip registers with the pilot of the cut-olf knife, the strip element is constituted an element in the operating mechanism and the severing mechanism is thereby rendered positive in its action as it is not dependent upon frictional Contact or other variable elements employed in prior art devices.

Attention is also called to the coordination of the moistener with the cutoff or severing mechanism by means of Which the moistening element is kept out of contact with the strip until the latter has been severed which is at the time the gummed portion of the strip is passing over the region of the moistener. This is another decided advance in apparatus of this kind.

It Will be evident from the foregoing description of this invention that dispensing and severing mechanism made in accordance therewith is of simple and relatively inexpensive construction and positive and eliicient in its operation of conducting the several functions for which it is intended.

ment has herein been illustrated and described, it will be obvious to those skilled in the art that various modifications may be made in the details of construction without departing from the principles herein set forth.
