or in other convenient positions for feeding or dispensing predetermined lengths of gummed paper strip or tape such as commonly used for closing or securing paper wrappings.

Referring to said drawings, Fig. 1 illustrates in perspective, parts being broken away, a suitable form of device or machine embodying an application of my invention, and Fig. 2 is a side elevation of the same, looking from left to right at Fig. 1.

3 and 4 indicate the sides or frame of the machine, spaced apart and held by suitable tie rods or bolts such as 5. 6 and 7, the bolt 5 serving as a hinge orpivotal bearing for the cover 8. The bottoms of the side plates are preferably provided with feet 9, 10 whichmay be provided with rubber or felt base portions, if desired.

Upon the inner sides of the walls 3 and 4, are suitably secured hangers 11, 12 in the bottom of which is seated a spindle 13, carrying a roll 14 of paper, adapted to unwind clockwise, the free end of the same being 39 indicated by the reference character 15.

Upon the lower tie rod or bolt 6, is pivotallv secured a strap or braking member 16, normally pressed against the roll 14 by springs 17. for retarding the unwinding of the roll of paper. 5 18, 19 indicate metallic straps secured as shown at opposite sides within the casing, and 20, 21 indicate side members pivotally mounted upon the spindle 22, which is threaded at opposite ends and provided with thumb nuts 23, 23' also threaded. so that. when the said thumb nuts are. turned in, the side guides 20, 21 are adjust-ably tensioned against theside of the roll 14, and

properlyguide the same. The wheel 24 is provided with cross pieces,

such as 25, which may be pulled by the fingers rotating the wheel 24 anticlock-wise. These finger pieces 25, are equally spaced a predetermined distance, say 3", and the outside of the case above the wheel indicated at 26, is marked with a scale indicating spacing from 3" to 24", so that, in order to cut a strip of gummed paper of predetermined length, the fingers are applied to the wheel at apredetermined point, and the wheel is pulled toward the operator looking at Fig. 1,

until the fingers strike the cut-ofi handle 27.

This handleis secured in the top of the lever 28,pivotally mounted at 29, and pivotally connected at the bottom to the link 30, which in turn is pivotally connected to the bell crank 31, pivotally mounted at 32, an expansion spring 33 being connected to the wall 4, and bell crank 31, as shown; The opposite end of the bell crank 31, is pivotally connected to the rod 34, which. in turn is pivotally connected at- 35. to the knife 36, pivotally mounted at 37, this knife bearing against the knife bar 38, beveled with a cutting edge similar to the cutting edge upon the upper surface of the knife 36, so that, as the knife 36 moves upwardly, by the action of the cut-off mechanism described, the free end 15, of the roll of paper, is cut off, and

the under side thereof, being suitably gummed, serves for securing the wrappings of packages, etc.

The operating wheel 24 is mounted upon a shaft 39, and this shaft carries a gear 40, meshing with pinion 43,1on shaft 42, which also carries a gear 41, which meshes with pin ion. 44. upon shaft 45. carrying friction rollers 46. 46'. which in turn bear against fric tion rollers 47, 47 upon shaft 48, which shaft is mounted in the side walls 3 and 4 with a little vertical play. the same being pressed downwardly by springs 49, 49', to insure proper frictional engagement or pressure for feeding the strip of paper from the roll 14.

50 indicates a suitable metal box, seated in brackets such as 51, and between the side walls 3 and 4, from which point it is easily removed. This box is intended to carry water and an inverted brush, the bristles 52 of which are in the path of movement of the gummed strip 15, a suitable flap 53 being adapted to lay against the side of the same. The cover 8, when thrown closed in the position shownin dotted outline at 8, also tends to press the strip with its under side gummed against the bristles 52, which apply the water thereto, so that the strip of prede termined length, when cut, is thoroughly moistened, ready for immediate application- 5 to the package or wrapping. Thus the entire operation of predetermining the length of strip required,"and of cutting and moistening the same, is provided for with a single sweep of the hand, the figures indicating the proper cross piece 25, according to the scale on the outside of the case, adjacent the wheel, and in rotating the wheel toward the operator and downwardly, the hand strikes the cut-ofi mechanism 27, after having fed the "required length of strip. The operation is thus rendered convenient, simple, expeditious, and certain, and of course, various modifications may be made in the construc- -ti6n and arrangement of parts without departing from the spirit of the invention as claimed. eI claim: a

1. .A strip feeding machine comprising a casing, strip feeding means therein, operating mechanism for said feedingm'eans comprising a rotatable wheel having a plurality of manually engageable, circumferentially spaced members thereon, a plurality of marks 0" lated with said wheel members, and means,

' acting in conjunction with the members on 1 the wheel, to predetermine. the lengths of V strip fed, dependent on the initial peripheral location of the member engaged by the operator.

2; A strip feeding machine comprising a casing, strip feeding means therein, operating mechanism for said feeding means comprising a'rotatable wheel having a plurality of manually engageable, circumferentially spaced members thereon, a measuring scale having a plurality of marks on the casing adjacent the wheel and correlated with said ,Wheel members, and means, acting in conjunction with the members on the.wheel, to predetermine the lengths of strip .fed, de-

pendent on the initial peripherallocation of the member engaged by the operator.

3. A strip feeding machine comprising a casing, strip feeding means therein, operating mechanism for said feeding means comprising a rotatable wheel having a pluralityof manually engageable, circumferentially and equally spaced members thereon, a plurality of marks on the. casing adjacent the on the casing adjacent the wheel and corre-.

wheel and spaced ap the circum erentia 'wheel members, and

rt the same distance as a means associated with the wheel and acting predetermining in conjunction therewith the lengths of strip-fed from the'inachine.

5. A strip feeding machine comprising a casing, strip feeding means therein,-operating means for said feeding means including a manually operatable wheel, operative connections between the wheel and said feeding means, manually. engageable members on sai wheel whereby said wheel can be rotated, a

path of rotation of said members and having marks thereon to indicate lengths of strip fed from the machine, the operative connections between the wheel and feeding means being so proportioned that the manualmovement of any one of the wheel members alongvthe scale will feed the strip a distance corresponding to the increment indicated on the scale.

6.
