Application filed May 9, 1921.

T 0 all whom it may concern:

Be it known that I, Cnns'rnn A. HULL, a citizen of the United States, residing at Peru, in the county of Miami and State of Indiana, have invented certain new and useful Improvements'in Handlerapping Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as willenable others skillet in the art to which it appertains to make and use the same. i V

This invention relates to an improved wrapping machine for winding a binding strip upon a handle used in connectionwith a basket, it being understood however that the machine can binding strip upon any articleof a similar nature which can be .fed longitudinally through a hollow drum in timed relation to the rotation of the drum so that as the drum rotates, the strip of binding materialwill be wound in a spiral about the article.

One object of the invention'is to provide an improved type of drum having an improved construction whereby the strip .of

the drum duringrotation thereof and at the same time, the'inner end portion of the strip caused'to feed into the central opening of the drum through which the article to be wrapped passes, to have the'strip of material wound about the same as thedrum rotates.

Another object of the invention is to so construct the drum that the strip of: binding material may have movement independentof the rotation of the drum and-thus permitting of a drag feed as the drum rotates to jwiiid the strip ofmaterial upon the article.

Another object of the invention, is to provide means for placing the strip or material wound upon the article under tension and thus keeping the portion wound tightly upon the article to be-bound.

Another object of theinvention is to provide a drum so 'constructedthat the strip of binding material ma be passed through one of the side disks of the drum into the proper position for engagement by the tensioning means and for winding upon the drum as the drum rotates.

' Another object oftheinvention is to provideimproved means for rotatably mounting the drum.

Another object of vide' means "for feeding the invention is to prothe article th o gh Specification of Letters Patent.

the drum, this feeding means including a toothed roller mounted upon a shaft which may be moved into and out of an operative position.

Another object of the invention is to pro vide improved means for placing a securing tack in the binding strip after the article has been bound and improved means for cutting off the strip after being secured.

Another object of the invention is'to provide a device which will be very easy to operate and which will be so constructed that the strip of binding material will be easily wrapped upon the handle or other article.

This invention is illustrated in the oompanying drawings, wherein:

Figure '1 is a view showing the improved machine in side elevation.

Figure 2 is a front elevation of the improved machine.

Figure 3 is a proved machine.

Figure 4: is a fragmentary view showing the drive element of the feeding mechanism top plan view ot the im moved to an inoperative position.

Figure 5 is a sectional view taken along theline 5-5 of Fig. 2. it

Figure 6 is a sectional view taken along the line 6--6 of Fig. 5.

Figure '7 is a sectional view taken along the line 77 of Fig. 5.

This improved binding machine which is used for placing a wrapping upon the handle of a basket is provided with a frame having-side members 1 and 2, each of which is U-shaped as shown in Fig. 1 and has its depending standards connected by a cross bar 3, the cross'bars carrying bearings to rotatably mount the drive shaft at which will be rotated in any suitable manner. In the present illustration, there has been provided a pulley 5 about which a belt 6 will pass but as previously stated, it is to be understood that any suitable means could be substituted belt shown. The side members of the frame are connected by 7 so that the side members will be securely braced and held in the proper spaced relation.

The drum or strip carrier is provided with a hub 8 which is hollow as shown in Fig. 6

'9 which is secured to the hub by securin bolts or rivets I0 and provide a Gii'Gumerentially and provided with a clamplng ring securing bolts 17 opening formed which may be termed strip 24 will be connected,

extending channel or seat in which a sprocket wheel 11 is positioned and secured by the fasteners 10. This sprocket wheel is engaged by the sprocket chain 12 whiclralso passes about the sprocket wheel 13 of the shaft 4 and it will be readily seen that when the shaft 4 is rotated, rotary movement will be transmitted to this hub 8. A. bearing ring 14 is carried by supporting strips 15 secured to the upper cross bar of the side member 1 and this bearing ring extends through the clamping ring 9 and has a disk or ring 16 secured to its inner end by securing bolts 17 It will thus be seen that the hub of the carrier will be rotatably mounted upon this bearing ring 14 but that when desired, it may be removed by releasing the nuts of the so that these bolts can be removed. Brackets 18 are secured. to the outer face of the bearing ring by certain of the securing bolts 17 and have up er and lower bearing arms extending into t e interior of the ring as shown in Fig. 6 so that guide rollers 19 may be rotatably mounted in a vertical position within this bearing ring as shown in Figs. 5 and 6. Relatively large disks 20 and 21 are secured tothe sides of the hub by fasteners 22 which in addition to mounting the disks 20 and 21 will also serve to rotatably mount rollers 23' as shown clearly in Fig. 7.

When the drum is being rotated to cause the strip of binding material 24 to be wound about the rollers 23 and wound upon the handle 25 with which the inner end of the it is desired to have this handle fed through the drum and between the guiding rollers therefore been extension 28 of this side member 2. There'has also been provided a feeding roller 29 having a toothed head 29' for engaging the handle and feeding the handle between the rollers when this feeding roller 29 rotates. This feeding roller is mounted upon the upper end of the shaft 30 which shaft extends through a slot 31 formed in the side extension of the side member 2. The lower end of the shaft 30 a driven shaft, is rotatably mounted by means of a bearing 32 and carries a worm-gear 33 which meshes with a worm carried by the driving shaft 4. It

will thus be seen that when the shaft 4 is rotating, rotary movement will be transmitted to the driven shaft 30 and when the shaft 30 is in the vertical position shown in Fig. 1, of the roller 29 will engage the handle and force the handle longitudinally throughthe drum. This shaft 30 is permitted of swinging movement so that it can be drawn to the inoperative position of F ig. 4

disk 21. passed through the hollow hub and will be when it is desired to stop feeding of the handle. In order to permit the shaft t o be readily drawn to the inoperative posltion against the action of the spring 34, which normally holds it in the operative position, there has been provided a strip 35 which is loosely mounted upon the shaft and passes through a loop 36. This strip 35 is provided with a side notch as shown at 37 so that when the shaft has been drawn to the inoperative position of Fig. 4, this strip 35 may be swung to engage the guiding strip 36 and thus provide a latch element. As soon as it is desired to have the handle feed through the hub again, it is simply necessary to swing the latch to the position of Fig. 3 and the spring will return the shaftto the operative position as shown inthis figure.

When this device is in use, the strip of binding material will be led from a source supply and passed through the eye 88 o the guide 39 and will then be passed through the slot 40 provided in the outer The handle will first have been in position to receive the end of the binding strip which will first however be passed between the blocks 41 and 42 carried by a strip 48 secured to the inner disk 42 is pivotally mounted and engaged by a spring 44 so that it will be yieldably held in engagement with the block 41 and will thus provide pressure against the binding strip to hold the portion of the strip wrapped about the handle under tension. When the binding strip has been passed through the tensioning Ineans'and connected with the handle, the shaft 4 can be rotated and rotary movement will be transmitted to the drum. As the drum rotates, the binding strip will be wound upon the'drum about the rollers 23 and at the same time, the inner end pore tion of the strip will be drawn inwardly off of the drum and carried about the handle so that it is wound upon the handle. During rotation of the drum to wind the strip upon the handle, the handle will be moved longitudinally through the open central por tion of the drum and therefore the strip will be wound upon thehandle in a spiral so that the handle will be neatly wrapped and completely covered by the strip of binding material. This binding material is wrapped loosely upon the spool or. other source of supply and therefore when the inner end portion is drawn upon the strip will not bind and tear. The fact that the strip is wound about rollers will also permit of it being readily drawn into the interior'of the hub. The friction blocks or tensioning blocks 41 and 42 will hold theportion of the strip wound about the handleunder 20. The blockproper tension and therefore a close and After the strip of binding has been wound i iiavev upon the handle as much as desired, the strip should be secured to the handle. There has therefore been provided a plunger d5 which extends through an opening formed in the hub 8 andis provided with a cross pin as engaging a spring t? so that the plunger or hammer 45 will be normally held in an inoperative position. This plunger is formed of magnetized metal so that when a tack is placed against the inner end of this plunger, it will be held in proper position to be driven into the handle when the plunger is moved inwardly by the operating lever i8 which is pivotally mounted upon the bearing bar it). It is also desired to permit the strip to be readily cut off close to the point where the tack passes through the strip and therefore there has been provided a cutting plunger 50 which is also slid-ably passed though an opening formed in the hub 8 and provided with an abutment engaging a spring 51 for drawing the plunger 50 to an inoperative position. From an inspection of Fig. 1, it will be readily seen that when the lever 48 is swung to move the hammer 45 inwardly, it will not engage the cutting plunger or chisel 50. If it is desired to cut the strip a plunger 52 which is slidably connected with th lever i8 by brackets or guides 53 will be moved clownwardly against the action of the spring 5r so that its head 55 will be brought into position to engage the outer end of the plunger 50. Therefore, when desired, the plunger 50 can be forced inwardly to cut the binding strip close to the tack which has been previously forced into the handle by means of the plunger &5. lhere has thus been provided a handle wrapping device which is easy to operate and which is very eiiicient in operation and which will wrap ahandle with the wrapping neatly applied and firmly held in place.
