The band is placed aroiind a forin of the vdesiired' shape, the top is laid 'upen the form to be flush with the upperedge" of the bzu chend the extended portion ofthe striii' ie folded over uponthe top and ad heredthereto; thus uniting the top and band. T he present invention embodies the manner of sup orting and holding a box band during the process of securin a? strip thereto,

the band holder being" secured upon a clutch controlled power driven shaft which is inouhtedon the strippinginachine, the holder being; in position, to receive a strip supplied" from said machine and which is coated with glue on one side. H

Referring to the accompanying drawings The improved box band holder A. is in the forin of a ring like dvicewhieh is' nade up of half round sections 1 i and 2' which are formed on one" side with registering hinge 45', the holders being of Varying diameters to suit boxta'nds 0f Varying sizes, and about ajn' nch and a half wide. The inner fairies of'th'e sectiohs'l an'dZ are formed with integral strengthening ribs 5, and the outs'i'cle srirface's of the" sections are formed 3:

meet-ere sections. v Upon the inner face i of efieli section: and on the opposite side thereof from the hinge,- is secured en angle pl'a te 7, by screws's which pass through slots 9 in the"1nen1'ber 10 of the an le plate and into thesection. The members 11' of these angle ijla tes are normally parallel and sep'zirz'ft'ed by e;- spa'oeflof about three quirters of an inch, and each of these nie nherslm's fornfed on its inner side, a central longi-. tudinal rib of slight depth. The 'angle plates? are the sanievvidth as the ring sections and an integralbraeing Web 13 con iiect s thfe two embers of each e fiat arm 14 extends across the rear side (if the he'lder an d is seeiired it one end to hinge pin fl.

A hand lever 22'is secured in the outer end of the spreader stem, and stop pins 23 and 24 project from the arm 14, which engage the set screw 21, and

define the opening and closing movements of the spreader, as will be understood by reference to Fig. l. When the spreader is in the position shown in Fig. 1, the band holder is closed,

and when the spreader is in the position shown in Fig. 4:,the band. holderis opened or expanded so as to fit tightly within and thus grip a box band placed thereon. A coil spring 25 is connected at one end to the rib 5 of section 1 and at-its opposite end to the rib of section 2 and this spring is under pulling tension so that the sections are spread or expanded against the action of the spring and drawn toward each other by the action of the spring. The end of the arm 14 which supports the spreader is heldto the band holder ley-the engagement of the flange 19, of the spreader with the ribs 12 on the angle plates 7 ,-and this engagement not only relieves the strain onthe hinge connection but prevents any uneven movement of one section with respect to the other section 1n either expanding or contracting the holder.

Afitting, comprising an internally threaded hub-26, having laterally extending apertured ears 27 on one end, is secured to the I arm 14, by screws 28 which extend through the arm and through the said ears, the axis of'the hub 26 coinciding with the axis of the holder. The hub 26 receives a threaded plug 29 which is rigidly mounted on the end I of a power driven shaft 30 which supports I and rotates the band hold and this shaft forms a part of a stripping machinein commen use and which therefore forms no part of the present invention, enough only of this machine being shown inFigures 6, land 8 to illustrate the manner in which the expansible holder is supported in the operation of applying a strip to a box band, it being understood that the improved holder is used. only in connection with the bands of round boxes and boxes having a curved out line, such as the heart shaped box, other forms being used for the bands of rectangular boxes and others not having'curved outlines; such forms being connected to the shaft 30, in the same manner'as the present expansible holder or as shown in Fig. 2.

A brief description of the strippingmachine will sufiice. The'shaft 30,is supported in a bracket 31, on the outer end of an arm 32 mounted in a support 33 on'the end of a table 34. The shaft 30, carries a bevel gear 35, which meshes with a similar gear 36, on the outer end of a shaft 37 supported onthe arm 32. This shaft carries a bevel gear in abl mounted on the shaft and operatedyby,

a pusher 41 on the end of a rod 42 which is slid by means of a foot lever 43, bell crank 44, and connection 15 between foot-lever and bell crank. j

A stationary knifeAG is supported on a bracket 47 011 the upper end of a standard 48, mounted in a bracket 49 on the. end of the table 3 1. A knife 50, is supported on a. bracket 51, pivotally connected to v the bracket 47, and operated by mechanism (not shown) to be swung upward and then allowed to drop by gravity so that its knife 50. will 'coact with the stationary knifedfi, to sever a strip passing between them, with a shearing .cut. The strip 52. passes over a glue distributor, (not shown) on the rear end ofthe table, and thence over suitable supports, as 53, and then between the cutting knives, and a portion of the strip is passed around the box band, and severed from the main part of the strip, upon each rotation of the band, as will now appear.

In practice, the band to be stripped is placed around the holder so as to extend be yond the front edge thereof, as shown in Fig. 9, and the hand lever 22 is swung upward so as to turn the spreader from. the

position shown in Fig. 1, where, its long diameter is ona horizontal line, to the position shown in Fig. 4, when its long diameter is on a vertical line, thereby spreading sections 1 and 20f the holderso that they fit tightly within the band and thus grip it; the angle plates being so adjusted, that the cam or spreader when in a vertical position will spread the sections .just far enoug'hto grip and hold the band, and not far enough to cause them to part or break the band at the point where its-two ends are taped or connected. In. this position of the spreader, the set screw'21, engages the stop pin 2% andprevents further inovement of the spreader as, will be understood by reference to Fig. 4. I I

The strip 52, which is glued on its under side, is about an inch widerthan the band, so that itwill extend a half inch beyond each edge of the band. The attendantthen attaches the free end of the strip to the band, as shown in Fig. 6, and depresses the footlever 43 by which the clutch 40 is coupled toare rotated, as above described and when the holder has made a complete rotation thereby causing the strip to adhere to the band, the knife 50 drops automatically and severs the strip and the loose end of the strip encircling the band is pressed against the band by the attendant, this loose end being long enough to overlap the other end. The attendant then depresses the foot lever to again rotate the holder, and as it rotates, the outer projecting edge portion of the strip is tucked or folded in, manually against the inner face of the band, as shown by the dotted line X, Fig. 9, and the stripping operation is completed. The hand lever 22 is then turned to the position shown in dotted lines Fig. 4, which permits the spring 25 to retract the sections of the holder and re lease the band, which is then removed and is ready to receive the top or bottom, as the case may be.

The ribs or projections 6 on the surface of the holder, not only act more effectively to prevent slipping of the band on the holder, but they also prevent accidental contact of the glued strip with the surface of the holder; as it is apparent that if the surface of the holder were perfectly smooth, contact of the glued strip therewith would result in the strip adhering tightly to said surface, thereby causing annoyance and loss of time.

Having described my invention, what I claim as new and desire to secure by Letters Patent is p 1. In mechanism of the character described, a ring-like holder comprising two half round sections having a hinge connection, projections on the free ends of said sections which are parallel and spaced from each other, a rotary spreader supported between said projections and a coil spring connecting the sections to resist the spreading movement.

2. In mechanism of the character described, a ring-like holder comprising two half round sections having a hinge connection, projections on the free ends of said sections which are parallel and spaced from each other, an arm on one side of the holder and connected at one end to the hinge, a spreader pivotally mounted in the opposite end of the arm and extending between said projections and a coil spring connecting the sections to resist the spreading movement.

3. In mechanism of the character described, a ring-like holder comprising two half round sections having hinge knuckles connected by a hinge pin, an arm on one side of theholder secured at one end to said hinge pin, spaced parallel projections on the free ends of said sections, an elliptical spreader between said projections and pivotally mounted in the free end of said arm, a rotatable support connected to said arm and a coil spring connecting the two sections to resist the spreading movement.

t. In mechanism of the character described, a ring-like holder comprising two half round sections having a hinge connection and adapted to receive a box band, an arm connected at one end to said holder and extending across one side of the same, angle plates secured to the free ends of said sections, an elliptical cam positioned between said angle plates and pivotally mounted in the free end of said arm, a lever for turning said cam thereby to spread said sections to grip the box band, a coil spring connecting the sections to resist the spreading movement, and a rotatable support connected to said arm in line with the axis of the holder.

5. In mechanism of the character described, a ring-like holder comprising half round sections having a hinge connection, inwardly projecting plates on the free ends of said sections, an arm extending across one side of said holder and connected at one end thereto, a spreader pivotally mounted in the free end of said arm and extending between said plates, said spreader being elliptical in outline whereby when the spread er is turned to bring its long diameter at right angles to the faces of the plates, the sections of the holder are thereby spread, a coil spring connecting the sections to draw them together when the spreader is reversed, a flange on the outer end of said spreader which engages said plates, and a rotatable shaft connected to said arm in line with the axial center of the holder.

6. In mechanism of the character de-' scribed, a ring-like holder comprising half round sections having a hinge connection, the outer surfaces of said holder being formed with spaced transverse projections, means for spreading said sections to grip a box band placed thereon, a spring connecting said sections to resist the spreading movement of the sections, a support secured to said holder and in line with the axis thereof, and means for rotating said support.

7. In mechanism of the character described, the combination with a shaft and means whereby the same may be rotated at will, of an arniconnected to one end of said shaft, a ring like holder comprising half round sections having alined hinge knuckles, and a pin which passes through said knuckles and into one end portion of said arm, a cam rotatably mounted in the opposite end of said arm for spreading said sections and a spring connecting said sections to resist the spreading action, said shaft being in line with the axis of said holder.

In testimony whereof I aftix my signature.
