APPARATUS FOR PROVIDING BOXES WITH CLOSURES.

I Specification of Letters Patent.

Patented Dec. 1'7, 1912.

Application filed December 2, 1911. Serial No. 663,633.

JENKINS, citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Apparatus for Providing Boxes with Closures, of which the following is a specification, reference being had therein to the accompanying drawing.

The object of this invention is to provide an improved automatic machine for rapidly supplying open paper receptacles with paper closures cemented in place. For illustration the receptacles chosen are previously formed short cylindrical tubes, and the apparatus is employed for closing one end ,of each tube by cutting a disk from a strip, flanging, and

inserting it after suitable adhesive has been applied.

In the drawings Figure 1 is a side elevation of a machine embodying the invention. Fig, 2 is an elevation of the same machine, looking from the left of Fig. 1. Fig. 3 is an enlarged plan view of the central portion of the machine with the upper portion of the frame and some other parts removed. Fig. 4 is a vertical section show-' ing the disk cutting and closure-inserting devices. Fig. 5 is a section on the line 5-5, Fig. 4. Fig. 6 is a side elevation, partly in section, showing paste applying mechanism. Fig. 7 shows in elevation the left hand end of the apparatus seen in Fig. 6. Fig. 8'

shows in like manner the opposite end of the same apparatus. Fig. 9 is a section on the line 9-9, Fig. 8. Fig. 10 shows in elevation a portion of a receptacle feeding wheel and its actuating mechanism. Fig. 11 is a side elevation of a cam hereinafter mentioned. Fig. 12 is a plan view of a device for winding the scrap or remnant of the disk stripi Fig. 13 is a fragmentary elevation illustrating the discharge of the receptacles from the wheel which carries them. Fig. 14.- is an end view of a scrap drum seen also in Fig. 12. Fig. 15 is anelevation of devices. Fig. 16 is a plan view of the de- I vices in Fig. 15. Fig. 17 is a detail elevation of parts of the apparatus of Figs. 15 and 16.

In these figures, A represents the supporting frame of the machine, B a receptacle-carrying wheel, and G a power pulley,

moving parts of the machine. The wheel B is mounted upon a shaft B directly below the shaft C and is provided with a series of circumferential radial pockets B each of which is open on one side and also at its peripheral end. This wheel is rotated step by step by means of.'the power shaft C (Figs. 1 and 2) spiral gears C C, an oblique shaft 0*, gears C C shaft O crankplate C and a stud C which at each revolution of the disk enters one of a series of open. recesses B in a ring B fixed on the lateral faces of the wheel B, the parts being so proportioned that each movement of the wheel corresponds precisely to the angular distance between the axes of any two consecutive pockets of the wheel, and during the time while the wheel is out of engagement, the wheel is held immovable by a mutilated disk C, Fig. 10, this portion of the driving device being a form of the wellknown Geneva movement.

The receptacle bodies D are fed into the pockets of the wheel by a chute D, Fig. 2, down which they roll by gravity to enter the ascending pockets as they reach in succession the plane of the wheels horizontal diameter, and as they move upward with the wheel, they are prevented from leaving the pockets by a fixed plate D Fig. 2. Each body after it begins its ascent with'the wheel has the interior of its outer end provided with adhesive during a period of rest, by mechanism seen in Flgs. 1, 6, 7, 8, where E is a paste receptacle from which a wheel E transfers adhesive to a rotary brush .E which is at proper times moved bodily in a direction perpendicular to its plane into and out of the mouths of receptacles carried in the pockets B and each held temporarily at rest in position to receive the brush. These devices are driven from the shaft C by gears F (Fig. 2), shafts F, F having universal couplings, and gears F F on the shaft F Thear F drives a gear F on the shaft F of t e paste wheel E, while the' mounted on a shaft 0 for actuating-all the l which is'such that the shaft is pushed longimouth of the Waiting receptacle, and as this aperture is of materially less diameter than the brush, the peripheral flexible portion of the latter is retarded until the body of the brush is well within the receptacle when the continued advance frees the brush from the plate. When thus freed, the brush instantly assumes its normal plane form and comes into contact with the interior of the receptacle. The plate thus performs the double office of removing surplus paste from the brush and preventing the advancing brush from applying adhesive to the end face of the receptacle wall, the latter result being of very great importance. As soon as the rotating brush has rubbed its glue or paste into the interior surface of the receptacle, the camallows the spring to restore the brush to initial position, and it is to be noted that the brush now carries little paste and that in moving outward there is little tendency to leave'paste upon the end of the receptacle. The plate is preferably removably held by the paste receptacle so that it may be readily removed and cleansed, and it is so placed that paste dripping therefrom falls back into the receptacle. After receiving its adhesive, each receptacle advances step by step until it reaches vertical position at the top of the wheel where it is supplied with a cup-like closure by devices to be described.

The closures are formed from, a paper strip G from a roll G, Fig. 1, this strip being fed forward by rollers G2 actuated from the power shaft by a pawl J connected with ordinary devices on the power shaft bya rod J and engaging a ratchet J 2 on the shaft J of one feed roller. As the strip leaves the feed rollers, it passes between plane plat-es G, G, Figs. 3, 4, and thence over a fixed die plate G, where its margins are still held in grooves G. Here .a disk X is cut from the strip, while it is at rest, by the descent of a die G" carried by a long bar G hinged at G and having its free end raised and depressed at proper times by a rod Gr provided at its upper end with a roller G engaging a cam G on the power shaft C,

Figs. 2'and 11. Immediately after the cut-.

: ting of the disk a reciprocating plunger H,

out novelty, forming the disk into .cuprshape' concentric with the die but of materially less diameter, is forced down. by devices withand forcing it into the waiting receptacle. On the retraction of the plunger, the wheel '13 brings another receptacle to place, and

the operation just describedis repeated. In

a rapidly running machine the working parts must be guarded from the scrap or unused portions of the strip. This is done by providing a reel or drum 1, Fig. 1, upon which the scrap is wound, the drum being driven by an elastic belt I, from the power shaft, which permits slipping as the roll of scrap increases- The drum is free at its outer end so that the material may he slipped off from time to time and thrown aside, and to facilitate attaching and detaching the strip, the drum" is provided with an open slot I Figs. 12 and 14. Tension upon the strip is adjusted by means of a spring I and a thumb-screw I regulating the pressureof the spring upon the barb of the belt pulley 1 As a further protection, needed 1f the scrapstrip breaks, I provide below the strip a shallow trough I extending from the die plate nearly to the scrap drum.

It may sometimes happen that by some chance an empty pocket arrives at the top of the-wheel, and in such case it is desirable to avoid cutting and forming a closure and depositing it in the unoccupied pocket. lDevices are, therefore, provided for automatically arresting the feeding of the closure strip, in such cases, and in this case such devices hold the feed pawl J out of engagement at the proper time. For lifting the pawl and holding it temporarily in raised position, I mount on the pawl-carrying arm J and just below the pawl, a rocklng block J 5 having an arm J 6 which normally rests on a sleeveJ" sliding on the feed roller shaft and having a segmental peripheral flange J 8 alongside the vertical plane of the arm J. The sleeve is connected by a link J to a lever J centrally pivoted at J to the frame and having at its opposite end a roller J which a spring J urges toward the lower end portion of receptacles D when at rest in the wheel pocket which will at the next advanceof the wheel be brought beneath the cutting and inserting devices. The flange J. is normally at a slight distance from the plane of the arm J but when the roller J the feed-pawl J from the ratchet wheel J and then travels along the periphery of the flange J until the arm J begins its return movement. One strip feeding step. is thus omitted, and the cutter and plungerat' their.

next succeeding movements find no stock beneath them. After the roller J has swung inward as described, it is pushed outward by the portion 4 of tlie wheel B at the next advance of the latter, and the flange J a 'being thus withdrawn from the path of the arm J feeding goes on in the normal man ner. 3

, As clearly appears in Fig. 2, the pockets B are so formed that when the receptacles D are descending after receiving their closures, they"tend to roll out of the pockets, and as soon as they pass the plate D they roll out of the pockets intoan inclined discharge chute K, Figs. 1 and 2.

What I claim is: 1. The combination with a vertical wheel having a series of peripheral, outwardly and laterally open pockets for receptacle bodies,

of means for delivering such a body sidewise to each pocket upon the ascending side of the wheel as it rotates, automatic means for rotating the wheel by steps equal to the distance between the azies of successive pockets, to bring each to rest at a predetermined point, and a die and plunger arranged to form and insert a closure in each body while thus at rest.

2. In apparatus of the class described, the

combination with a receptacle for adhesive, of a rotary shaft bearing a disk extending into the receptacle, a second shaft bearing a rotary disk brush normally in contact with CHARLES FRANCIS JENKINS.
