Specification of Letters Patent.

Patented Apr. 27, 1915.

Application filed July 29, 1914. Serial No. 853,875.

To all whom it may concern:

Be it known that I, CHARLES A. LEE, a citizen of the United States, residing at Neenah, in the county of Winnebago and State of lVis'consin, have invented a new and useful Wire-Hoop Forming and Applying Machine, of which the following is a specification.

My invention relates to a machine for applying a wire hoop upon a turned article of wooden-ware, such as pails of various diameters and tapers, forming a look upon the hoop, cutting the wire off of the required length for the hoop, and bending each end into a rightangled prong adapted to be driven into the wood of the pail being hooped.

It consists of a suitable frame for supporting .the mechanism, a conical block or form, for supporting the article to be hooped, a reel from which wire can be unwound as wanted, a wire gripper for seizing the wire and winding it a little more than once around the article being hooped, means for revolving said gripper, a hoop lock forming tool and a prong forming and wire severing tool, said tools to be brought into use in the order named.

The mechanism is shown in the accompanying drawings, in which,

Figure 1 is a plan or top view of the machine. Fig. 2 is a front side elevation of the same. Fig. 3 is a rear side elevation thereof. Fig. 4 is an elevation of the left hand end of Fig. 1. Fig. 5 is a longitudinal elevation of a variable tapered block upon which the article to be hooped is supported while the hoop is being applied, all but two of its covering staves being removed and a part of its stave securing flange at the larger end being in section. Fig. 6 is a plan of one of the covering staves for the conical block. Fig. 7 isv an end elevation of Fig. (3. Fig. 8 is a trans verse section through slots therein of the larger of the two heads upon which the covering staves are mounted. Fig. 9 is a plan of the outside of Fig. 8.

Fig. 23 is a section across the lock forming tool channel taken upon a line just in front of the stem of said tool in Fig. 2. I

Similar numerals and letters indicate like parts in the several views.

\Vhile the device is designed for forming hoops of wire upon turned articles of wooden-ware, it should be understood that in the use of the term pail, that it includes all articles of turned wood for which wire hoops are adapted. It will be understood that when pails are turned that are intended to have wire hoops applied, that a truss hoop is driven on, and remains there until the bottom has been inserted and the wire hoops applied, when it is removed for future use.

1 indicates a frame as is shown in Figs. 1, 2, 3 and 4, but no particular form is essential, .its base 2 extending rearwardly for forn'iing a support for the shaft upon which the pail is mounted while being hooped.

Mounted to slide in keepers 3 is a block 4, upon which is mounted for revolution in tubular box 5, a shaft 6, upon the front end of which a conical block 7 is mounted which can revolve with the shaft and move endwise with the block 4. The block at is provided with a lever 8, which for convenience in access. to its pivotal point, is connected by a rod 9 with a pivotal boss 10. Just above the lower end of lever 8, a rod 11 extends to and connects with the block 1. The lever extends upward to a convenient ,point forv the operator to reach. A latch 12is pivoted at 13 and is provided with a plurality of notches 14 for holding the lever in the desired position, and with a spring 15 for normally holding the latch closed. The purpose of this lever is for moving the block 7 endwise for adjusting the position of a pail thereon for receiving a Wire hoop near its top, and also one at its bottom, the notches 14 being arranged in the position required for so doing. Another notch can be made between those .for the purpose of adapting the machine for applying a middle hoop if desired. F or thepurpose of not obscuring the block 7 a pail thereon is indicated by dotted lines P. For revolving the wire gripping tool around the pail, gear Wheels are employed that are arranged as shown in dotted lines in Fig. 22, the right hand one 16 being mounted upon a shaft 17, which is journaled in the frame 1 and extends through the frame and hasupon its outer end a sprocket wheel 18. Near the other end of the frame another shaft 19 is mounted for revolution having upon it a sprocket wheel 20, a friction clutch pulley 21, clutch flange 22, and a clutch operating arm 23, which is arranged between collars 23 and is connected by a rod 24 with a clutch operating lever 25, pivoted at 26 to a holder 27 upon the frame 1. The shaft 19 is provided with a spline 19*, which engages the clutch flange 22. By operating this lever 25 the pulley 21 can be made fast or loose. A chain 28 runs around the wheels 18 and 2t, and is provided with a tightener pulley 29. The intermediate gear wheel 30 is mounted upon a stub shaft 3]., extending from a flange 32, which is secured to the frame 1. (Shown in Fig. 1G). The large gear 'wheel is a ring 33, which is arranged to be revolved within a channeled casing- 81:, the bottom of its channel being broken for the meshing of the intermediate gear 30 with the larger one, see Figs. 15 and 22 for the form of the easing, which is adapted to be secured to the frame 1 with screws 35. The gear wheel shaft 17 is provided with a crank 36, by which to turn it, so that it can be revolved either by hand or power. A reel 37 is arranged for revolution at the left of the frame, upon which wire 38 is wound. The reel is preferably made easily removable for the purpose of having a filled reel on hand to replace an empty one and prevent delay in the operation of the machine. This is effected by mounting the reel upon the shaft 39, which is provided with a square collar 40 fixed to the shaft outside of the reel head and forming threads 41 upon the opposite end of the shaft and also in the arm 42,

and" screwing the shaft into the arm and then screwing a nut 43 upon the shaft. 1 Upon removing the nut and unscrewing the shaft, an empty reel can beremoved and a.

filled one substituted. The reel is provided with a crank 44, outside of the collar 40, upon the round end of the shaft and the crank is made to turn the reel by extending a pin 45 from the crank into the reel head.

where it is loosely fitted. The crank is secured to the shaft by screwing a bolt 46 into the outer end of the shaft 39.

As it is necessary to give to the wire as it' is wound. around the pail various degrees of tension, pails for holding dry material requiring a less degree than those for holding liquids, it is necessary to apply abrake to the reel so that the wire can be drawn tightly around the pail. This is eflected by placing a washer (preferably in two parts, one of metal 47, and the other a compressible one, as leather, 'ber, &c., 48) between the reel and arm 42, and then by means of the square collar 40 screwing the shaft into the threaded bore of the arm 42 until the washer is compressed to the proper degree and tightening the nut 43 upon the outer end of the shaft 39. Between the reel and block 7, additional tension means is provided in two pulleys 49 and 50, which are mounted for revolution upon the frame 51, and which is pivotally mounted on the frame 1, at the point 52. The frame 51 is arranged to swing into different positions and can be held in one position by means of the latch 53, having a notch 54, for engaging the arbor of the pulley 49. The Wire from the reel is arranged to run from the reel around plurality of staves 61 (see Figs. 5 to 11 inelusive). The ware in a factory includes pails of'ditl'erent diameters and taper, and

it is necessary to have blocks for holding them of various tapers so as to accommodate pails of different sizes. The staves consist of pieces of wood of a suitable width and length curved outwardly in crosssection and each having a depending rib 63, and a depending curved tongue 62, the rib being provided with a straight lower edge of such width at its ends as will cause its free end to swing outward radially when the smaller head is moved lengthwise of the shaft 6. The large head 60 having been secured upon the shaft 6, the tongues of the severa'l'staves are placed in the slots 64 of the large head, which slots are of a form for fitting-around the curve of the tongues (see Fig. 8). The annular grooved flange 65 is then secured to the head (30 with screws 66. The groove 67 holds the staves upon the head, and as the circumference of the flange 65 is in near contact ,with the under surface of the staves, said staves, at the smaller end of the block cannot increase the circumference of the block at its smaller end so as to prevent the placing of a pail thereon. The head 59 is 1 spaced a little apart, forming a hub and a flange spaced from the hub and fitted in be tween the collars 70, making the end 72 of the rod, angularand adapted to receive a socket wrench as 73, by which the rod can be turned.

For winding the Wire around the pail in the process of forming the hoop, a wire gripper is used which is attached to the ring gear heel and is carried around with it. It consists olf a main or back piece 7 4, which is attached to the ring gear wheel 33, it having an arm ettmding downward for being also secured tlf reto. gral with it, a front piece 7 5, (broken away 'in Fig. 18,) between which two jaws 76 are pivotally mounted and between which jaws a cam 7 is mounted for oscillation, it being provided with an open ting arm or handle ,7 8. By raising the outer end of the handle,

an end of the wire from the reel can be inserted between the jaws through the slot 79, which extends from the bore 80 to the outer ends of the jaws, and then by pressing downward upon said handle the wire will be gripped, and in consequence of the form and position of the pivotal pointof the jaws the harder the pull upon the Wire, the tighter will be the grip of the jaws upon the wire.

The lock-forming tool is mounted to slide toward and from the conical block in the channel 81, The normal working position of the sliding rod of the tool is vertical with its jaws resting upon a pail and the axial line thereof in line with the axial line of the shaft 6, and it is to be moved to the right or left as the diameter of the pail requires for approaching that position. This sliding movement is made to take place simultane-imsly with that of the wire delivery device 55, by connecting an arm which extends from each by means of arod 82 with a disk 83, and attaching a crank 84 to the disk by which it may be turned. (See Figs. 1 and 17.) The lock-forming tool consists of a sliding piece 855, a supporting bar 86, pivotally mounted in said piece and having a tubular piece 87, through which a rod 88 is arranged to slide a limited amount. In the The back piece has inteinner end of the rod 88, a pair of jaws 89 are pivoted at 90, and are each provided with arms 91, which cross each other, and their tail ends, when the jaws are closed upon the wire, are just Within the circumference of the rod 88. A sleeve 92 is mounted to slide upon the rod 88 and engage with the arms 91 and close and hold the jaws closed. The sleeve is provided with links 93, which extend to and are pivoted at 94 to a lever 95, one end of which lever is pivoted upon a sleeve 96, secured by means of a set-screw 97 upon the rod 88. By operating this lever the sleeve 92 can be slid over the ends of the jaw arms and close and hold closed said jaws. Above or outside of the sleeve 96, a crank 98 is secured to the rod 88, by means of a set-screw 99. A wire having been wound around a pail upon the block 7, by means of the gripping tool, the lockforming tool is to be swung into a vertical osition with the crossed wires of the hoop lnclosed between the jaws 89, when a half turn is to be given to crank 98 and a lock as is shown in Fig. 14 will be formed.

After the lock is formed the lock forming tool is to be swung into a horizontal position and a device is swung into position for severing the wire and forming a prong upon each end for being driven intothe wood of the pail after the pail has been removed from the block 7. It consists of two similar spindles 100, mounted for revolution, each in a rectangular holder 0, having a round tapering end at, which acts as a shear in cutting the wire, said holders being mounted upona horizontally arranged plate 6, which plate is supported alongside of the frame 1, and the holders are secured to said plate with the T-shaped piece 7 and the screw 9. The plate e is arranged to swing in a horizontal plane upon the vertical shaft h, and is arranged for vertical adjustment by means of the nuts 71. Each spindle is a straight piece of round steel and has upon its rear end a cog wheel 7', the two wheels being in mesh and one being supplied with a handle is, by

which the two spindles can be revolved simultaneously. The cog vmeels are inclosed partly within bands Z, which connect with the back piece m, and a handle n is provided by which it can be swung into and out of its working position.

The outer ends of the spindles are each provided with a slot 0 across them of a width for easily receiving the wire of the hoop, and the tapering ends of the holders 0 have about (5/8) five-eighths of their ends back a quarter of an inch or more removed from their upper sides, so that whenthe spindles are turned into a position for the slots 0 to be horizontal, a wire can lie in a slot, and the taperingends of the holders will act as a shear for cutting the wire upon a partial revolution oh the spindl Th n the device is swung around upon a pail for operation, the slots are to be in the position shown in Fig. 21, at a slight angle from a horizontal and spaced a suitable distance apart for forming the prongs q, upon the hoop. Upon turning the spindles a half revolution nearly, and forming the prongs g, the slots 0 will be in the position shown in Fig. 12, and leaving theprongs in readiness;

for being driven into the wood of the pail. The hoop having been locked' around the pail it can be so left and another hoop made for the other end of the pail, when the block 7 must be moved lengthwise of the shaft 6, for adapting its position for a hoop upon its other end, when there are to be but two hoops. top hoop upon two pails, then change position of block and puta bottom hoop upon two pails and so on.
