MACHINE FOR FORMING AND BAILING PAPER FAILS.

Specification of Letters Patent.

Application filed May 3, 1911.

Patented Sept. 10, 1912. Serial No. 624,812.

To all whom itmoy concern: I [Be it known that I, HARRY-A. INMAN,

a citizen of the United States, residing at.

The invention relates to .such improve-- ments and consists of the novel construc-- tion and combination of parts hereinafter described and subsequently claimed.

Reference may be had to the accompany.- ing drawings, and the reference characters marked thereon, which form a part of this specification. Similar characters refer to similar'parts in the several figures therein. Figure l of the drawings is a view in front elevation of my improved paper-pailforming-and-bailing machine. Fig. 2 1s a side elevation of the same. Fig. 3 1s a horizontal cross-section of the same taken on the broken line 33 in Fig. 2, showing in top plan the bed-plate of the machine and certaln of theoperating-mechanisms. Fig. 4 is a horizontal section taken on the broken line H in Fig. 2, and showing in bottom plan the bed-plate and various link-and lever-connections mounted upon the underside thereof. Fig. 5 is a view in front elevation of the parts shown in Fig. 4. Fig.

Gis a view in front elevation showing cer- .tain of the mechanisms on a larger;- scale than in Fig. 1. Fig. is a view in sideeleration showing certain of the mechamsms on a larger scale than in Fig. 2. Flg. 8 1s a horizontal cross-section taken through the partly formed pail and the forming-mechanism. 9 is a similar view showing the folding operation completed and thebailends .driven' through the side-wings preparatory to clenching said ends. Fig. 10 is a similar view partly broken away, showing the bail-end clenched.- Fig. 11 is a plan view of the blank from which the pail is fbrmed.

This invention relates more particularly to a machine for automatically folding, and attaching bails to, paper-pails, such as the ordinary paper oyster-pail.

Certain objects of the invention. are toautomatically form or fold such a pail from a blank of paper-board previously cut to the proper out line and creasedalong the proper fold-lines; to automatically attach to such a folded pail a wire bail, by which the same can be carried; and to provide such a pail with a wire bail, the ends-of which are not exposed on the interior of the pail.

Other objects; will appear in connection withthe followin descrlption.

Referring to tie drawings wherein the invention is shown in preferred form, 1, represents the base of the machine and, 2, a-bed-plate or table fixedly mounted thereon and adapted to support the blank, 3,

(shown in Fig. 11') preliminary to the folding operation, and to cooperate with the other mechanisms'in folding the blank to proper form.. The bed is provided with an aperture, '4, down through which the blank is adapted to be forcedby a head or plunger, 5, vertically reciprocatory in slideways.

in an overhanging arm, 6, erected from the base of the machine. A yielding bed, 7, is supported by means of a spring-post, 8, withinthe opening, 4, in the bed-plate in line with the plunger-head, 5, said yielding bed being adapted to support the central part of the blank which forms the bottom of the pail, and which. is held clamped between said yielding bed and the plunger-head, 5,

during the folding operation. The plun erhead, 5, is mounted upon thelower on of a toothed slide-rack, 9, which is enga ed by a pinion, 10, fixed upon the same sha t with a pinion, 11, adapted to be engaged by a toothed rack on the crank-rod, 12, connected with a crank-disk, 4-6, operated in a manner hereinafter described, whereby a reciprocatingvertical movement is imparted to the plunger-head 5. As the plunger-head, 5, de-

scends through theopening, 4, in the bed-' plate, the bottom of the box is clamped be tween said plunger-head and the yielding bed, 7, and the blank is drawn down within the aperture, 4:, the walls of which serve to upturn the side-portions of the blank and partly fold the same'to approximately the cross-sectional form shown in Fig. 8. A pair of side-wings or flaps, 14, are thus formed on each side of the pail, which wings require to be folded in from the position shown in Fig. 8 to that shown in Fig. 9, so that the wings of each pair shall lap each other. This is accomplished toward the latter part of the descending movement of the plunger-head, 5, by means of two airs of oscillatory arms, 15, one of each pair being mounted upon a rock-shaft, 16, and the ot er of each pair upon a parallel rock shaft, 17, which rock-shafts have fixed thereon, respectively, rocker-arms, 18, which project into thepath of the descending yielding bed 7. The final descending pail therefrom.

In adapting the machine for automatically attaching the wire bails to the pails, I provide a carrier and holder for the bail in the form of a slide, 19, reciprocatory in slideways, 20, on the bed-plate, and having a pair of arms, 22, adapted to freely receive therebetween the folded pail, the body of theslide and said arms being formed with seats to receive a wire bail, 90, which can be placed thereon by hand; The seats for the ends of the bail on the arms, 22, are undercut at, 21, so as to overhang the ends of the bail. Suitable means which will be presently described are provided for automatically imparting to the slide, 19, inward and outward movements at proper times.

The inward movement of the slide, 19, is so timed that the bail-ends are brought o-pposite the lapping portions of the sidewings, 14, on the respective sides of the box upon the completion of the folding of said side-wings, and when thus located each of said bail-ends is engaged by a plunger, 23, which drives the end of the bail through the lapping side-wings and into an opening, 24, in a stationary upright folder, 25, which cotiperates with the plunger-head to fold upward the side-walls of the body of the pail. Each of the upright folders, 25, is supported only at its lower end and has its upper end projecting freely into the aperture in the bed with a free space on all sides between its free end and the walls of said wedge-shaped member, 31, in fixed relation to the plunger, 23, so that as the plunger, 23, moves inward to force the bail-end through the side-wings of the pail, the cam, 31,'will be forced against the stud, 30, caus-. ing a rocking movement of the rock-shaft, 28, whereby the clenching-arm, 26, is moved across the path of the inserted end of the bail, serving to clench the same as above described.

The thickness of the clenching-arm, 26, and the upright folder, 25, is sufiicient to prevent the end of the bail from penetrating the side-wall, 32, of the body of the pail, as will be seen'in Fig. 9. The stock itself of the lapping side-wings affords sufficient support to the bail-wire to enable the elenchmg-arm, 26, to bend the end of the bailwire to hook-form as above described.

When the bailing operation has been completed, the lungers, 23, with their wedges, 31, are with rawn, permitting the clenchingarm to be returned to its initial position by means of the coil-spring, 33; the slide, 19, is moved back to its outermost position, and the plunger-head, 5, is raised, carr ing upward with it the folded-and-bail ed pail. As the rocker-arms, 18, are relieved from pressure by the rising of the bed, 7, the Wingfolders are rocked back by means of'a coilspring, 34, which connects together a pair of ocker-arms, 35, fixed upon the respective root- shafts 16 and 17.

As a means for accomplishing the necessary movements of the slide, 19, and plunger, 23, in proper time-relation with the descending and ascending motions of the plungerhead, 5, I provide connections whereby all of said mechanisms are driven from a common shaft 37. A pinion, 38, on the shaft, 37, engages a gear-wheel, 39, on a shaft, 40, rotatively mounted in bearings, respectively on the bed of the machine, and on the upper end of the stationary post 47. The gearwheel, 39, meshes with a gear-wheel, 41, which runs loosely on a shaft, 42, which shaft is rotatively mounted in bearings on the frame of the machine.

In fixed relation to the gear-wheel, 41, is *one member, 43, of an intermittent clutch, the other member, 44, of which is feathered upon the. shaft, 42, and is forced into engagement with the clutch-member, 43, by

means of a coil-spring, 45. When the clutch-member, 44, is held in engagement with the clutch-member, 43. by means of said coil-spring, the rotary movement of'the gear, 41, will be transmitted to the shaft, 42,

upon the end of which shaft, 42, is fixed a crank-disk, 46, with which is connected the crank-rod 12. The movable clutch-member, 44, is at certaintimes forced out of engage ment with the clutch-member, 43, by means of a lever, 50, fulcrumed at, 51, upon a fixed bracket, 52, and having on its upper end a yoke, 53, engageable with the hub of the clutch-member, 44, and on its lower end a stud or cam-follower, 55, adapted to be engaged by a cam, 56, fixed upon the shaft 40. The cam, 56, is so shaped that upon the completion of the downward movement of the plunger-head, 5, the clutch is held open to permit the plunger-head, 5, to remain stationary during the bailing operation. A vertical rock-shaft, 57, is mounted at its lower end in a bracket, 58, projecting from the post, 17, and at its upper end in a bracket, 59, projecting from the base of the machine, said shaft having fixed thereon a rocker-arm, 60, upon the end of which is a cam-follower, 61, which occupies. a camgroove, 62, in a cam-wheel, 63, fixed upon the shaft, 40, whereby'rocking movements are imparted to said shaft 57. A rockerarm-,.64, on the upper end of the shaft, 57, is connected by a short link, 65, with one end of a link, 66, the other end of which is connected with a lever, 67,'fulcrumed at, 68, upon the underside of the bed-plate of the machine, and having a slotted end adapted to engage a stud or pin, 69, fixed to one of the plungers 23. The link, 66, is also connected with one end of a lever, 70, fulcrumed at, 71, upon the underside of the bed-plate, and having its other end connected by a link, '7 2, with one end of a lever, 73, pivotally connected at, 74, with a slide, 75, movable in a slideway on the underside of the,bed-plate. The other end of the lever, 73, is connected with one end of a lever, 76, fulcrumed at, 77, on the underside of the bed-plate, and having a slotted end, 78, adapted'to engage a stud or pin, 79, fixed to the other plunger 28. The lever, '73, being mounted upon the slide, 75, a movement of the link, 72, will impart a bodily movement not only to the slide, 75, but to the lever, 73, which is however free to rock upon its pivot, 74, to accommodate itself to the arc of movement of the end of lever, 76, with which it is connected. A 'pair of camshaped plates, 80 and 81, are mountedupon the slide,-7 5, in position to at certain times engage one arm of an angle-lever, 82, fulcrumed at, 83, upon the underside of the bed-plate, and having its other arm slotted and adapted :to engage a stud or pin, 84,

fixed to the slide, 19-, which stud or pin, 84,

projects down through a slot, 85, in the bedplate. j

The arms of the several levers are so proportioned as to accomplish the several movements in the order above described, and the cam-shaped plates, 80 and 81, are so located as to provide lost-motion in the operation of the lever, 82, at the beginning of the inward movement of the slide, 19, to allow a suiiicient interval for the folding operation before the bail is moved into position for the bailing operation, and at the beginning of the outward or return movement of the slide, 19, to allow the necessary interval for the withdrawal of the plungers, 23, before the return movement of the slide begins.

I make no claim herein to the features above shown and described which pertain to the bailing-mechanism, as such features form the subject matter of an application filed by me, December 8, 1911, Ser. No. 664,608, as a division of the present application.
