tends into enlarged

portions

59 and 60 at its ends and has attached to one end a gear 6| covered by a plate 62. The member 58 with the bore 63 is rotatably arranged on the post 55 and held in place by means of a screw 64 engaging the groove 51.

A substantially circular housing l65 is secured to the enlarged upper end 60 as yby screws 66 and by the' screws 64 to'the enlarged lower portion 59 and has attached close to one edge thereof a vertically extending angular member 61. To

the other edge is hinged as at; 6,8 al radialmem- A ber 69.

A cam member 10 is pivoted at 1| in the enlarged lower end 59 and at 12 inthe enlarged upper end 60, and has a level` 'E3 attached there- By means of the lever '|3,;thecammember 4 22 and particularly to Figures l, 2, 10, 1l and 12, a square post |99 is provided with a base with approximately the width of the rectangular area |68 to allow a sliding movement of the post |09.

At the top the post |99 has secured thereto a bar |Il9a, to slidably accommodate a U-shaped cross member having downward extensions IIZ'and ||3 and extending into arms ||4 and I |5. The arm I4 is provided with a downwardly extending shaft H6, accommodating sleeves ||1 `and ||3 towhich are secured springs I |9, the latter to engage the core 35 of the roll 36, when inserted into the top of the roll.

The arm H5 extends into a yoke |20 to en- 'gage a roller |2| loosely mounted on the extenmay be brought into engagement with the radial member 69. x

A vertically extendiny cam 14 is pivoted to the lower end 59 as shown at 15 and to the upper end 60 as at 16 and has secured thereto a lever 11, by means of which the cam 'I4 may be brought into engagement with the open end of the housing 65.

A shaft 18 is iournaled at its lower end in the platform 52 and carries a gear 'I9 tomesh with the gear 6| of the tubular member 58. At its upper end the shaft 18 passes through an arm 80 formed in the frame 54 and carries a bevel gear 8|, to mesh with awbevel gear 82 connected onA a shaft 83 and rotatably arranged in the bearing 34 formed on the frame 54. `A'set screw 65 is provided in the bearing 84 to lock the gears in any desired position, as may be seen from Figure '1.

A crank handle 89 is secured to the shaft 83, by means of which the bevel gears 8| 'and 82 and the gears 'I9 and 6| may be turned, thus rotating the tubular member 58 with all its connecting parts. f

A U-shaped handle 81-is connected to the framel 54 as at 88 to allow for easy manipulation to and from any of the display units 20 to which the dispensing unitj2| is to be connected, the operation of which will be described later.

The Ygear 6| is covered by a-guard 89, while the rest of the mechanism is enclosed by the back 90 attached to the frame 54and bythe housing 9|, which at the top 92 has a block 93 attached thereto, to provide a bearing for. the slidable rod 94. arc-shaped member 95 provided with a lining 96. The

rod

94,1,nay be locked` in `any-position ,by means of a set screw 91. as shown invFigures l, 2and7.

Pawls 98 are secured to the platform 52 `at 99 and normally held in a downwardiposition by springs |00. (See Figures -l and 2.) The pawls 98 terminate into hook portions |0| to engage the notches 5| inthe extensions v49 of the base andare held in such an engagement'bythe:

The pawls98 come into locking position with Referring now to thefcutting mechanism.

To thelatter is connected an sion |22 of the tubular member 58, the roller |2| being held in place by a bolt |23 and a washer |24. The roller |2| may be locked into the yoke by a latch |25 secured to the arm ||5 as at |26.

Thus it will now clearly be understood from the foregoing description that by the insertion of thesprings ||9 into the core 35 of roll 36e-nd the engagement of the base l0 within the space |08, the cuttingI unit 22 is thus brought in proper relation with the roll 36 and held in this =rela= tion by the latch member |25.

Secured at itsupper and lower end of post|09 as shown at |41 and |48, is a bar |40 toac'commodate a;slide.| 50, providedwith rollers-'|51 to engage the bar 49. The slide is provided with a handle |52. A circular cutting knife |53 is-rotatably secured tothe slide |50 at |54 and'held' in a fixed position by ascrew |55 in the slide |50, entering into one of the holesl 56 of the knife |53.' Thus only part of the cutting-edge |51 is in use at any time, as clearly shown in Figure 12, and if this part of the `knife |53 through extensive use-becomes worn, an unused section of the knifelmay be exposed by means of .the screw 655 and holes |56. By this arrangement theknife may be lused for a considerable length of time, before a'removal forV resharpening or-'replacement becomes necessary. f I

The post |09 is provided with extensions |58` having bayonet slots |59 to accommodate a bracket |60 of a metering device |6|'. The 5mechanism of this device is not shown, but connected with it is a downwardly extending shaft |62 jour# nailed in the bracketv |60. A gear |63 is secured` The shaft 65is `iournalle'd in a sleeve |68 pivot'ed" 'Ijhe"slide'|50 'is frictionally'held in its upper ppsitionby-'faball- |13-engaginga depression; 14, jthe balll beingY kept inengagement with,y the d e- ;p sion |14 bya'spring- |1-5jin a'nppening lili-'of post 0,9; thisopening beingf closed bya screw sliding'loiijthe bar |0hr by'meansof a screwv |18. vliiescribing now more' fully the operation ofthe invention, the springs I ||l-:of.fthe,cutting unit 22 are inserted into the coreof the roll from which the, material is to be dispensed, the basey |,l to biefplacedvhetween the, extensions 49 and` held withinthis'space by the forwardedge |06"of"the platform 52, which is locked in position with the display unit by means of pawls IOI, the latch also having been locked to the roller-42| of the dispensing unit 2|'. The end |3| of a roll"36, on the display unit 20 is fed between the friction rollers |66 and |61 and through the opening |30 into the dispensing unit 2| and within the circular housing 95 until the edge of the end |3| position by means of the ca-m 10 and lever 13, asv

shown in dotted lines in Figure 8 and in full lines in Figure 9.

When the desired amount or length as indicated by the measuring device has been wound on the roll 65, the gear mechanism and the yoke 95 with the lining 96 is then brought into engagel ment with the wound material vand locked by the screw 91 to prevent unwinding of the material; 6|, 19, 8| and 82 may then belocked by the screw 85. The bar |21 is then brought in close contact with the material |3| by means of the rods |28, cams |34, rods and |38, and the ratchet |4| and pawl I 45, thus holding the material clamped firmly within the slot |30. The slide with the knife |53 may then be moved downward on the guide bar |49 by means of the handle |52 and the knife |53 engaging the edge |8|lr of the post |09 will then cut and separate the dispensed material from the material still left on the roll. The gears may then be unlocked and the rem'aining end wound on the housing at which stage the wound material is then ready for tieing by strings or any other suitable means.

To facilitate easy removal of the tied up roll, the member 69 is brought back into its innermost position after the cam 14 has been released from engagement with the material |3|. The dispensing device 2| may then be disengaged from the display unit 22 and moved to any suitable place for the removal of the roll. v

To further facilitate the removal of the dispensed roll, the platform may be tilted and rested ljh'e cross member H is prevented; from Aonthe rollers =53""a11d1t1f1'e` handle 81"* aseshown by thedotted'flinesofFiguref. f
