To all whom it may con/ccm:

Be it known that l, (limones FnANcs Jnnnms, a citizen o'f the Unit-cd States, residing at Vlashington, District ot' Columbia, have invented certain new and useful lmprovements in lilaking lonas or Bottles, ot' which the following is a specification, ret'erence being had therein to the accompanyii'ig drawing.

The principal object of this invention is to provide automatic devices for presentingI open cylindrical boxes or bottles accurately in .position for receiving bottoms, and to this end an indefinite series of bottle bodies advancing step by step halts at such intervals that each bottle body rests for a momentvvhile it is provided-with a bottom, meansI being provided for securing accuracy ot position during the interval of rest.

For illustration, the invention is shov-:n as embodied in apparatus for making paper' milk. bottles, and in this special art the bodies of the bottles are usually .made up of spirally wound paper strips, and the bottoms are paper disks drawn in diesI to provide .each with an integral, down-turned marginal tiange in the form ot a short, cylinder snugly fitting the interior of the body. lt is, however, obvious t iat the invention ia not necessarily limited. to making bottles ot` paper, nor by the use that is made of the con'iplctcd bottles, or boxes, as they may bc called it used for solids instead oi liquids.

ln the dranf'ings, Figure l is a side elevation oi: the principal portion of a machine cu'ibodying my invention.. Fig'. L is a plan view of the same apparatuz-f. Fig'. 3 is an elevation looking from the side opposite that seen in Fig. 1. Fig. i is an end elevation. Fig. 5 is a section on the line SWB, Fig. l. Fig. G is a section on the line tj-G, Fig. l.4

In these figures, A represents the trame ot' an upright die press provided with a horizontal bed A from which rises a rigid die support A2, of inverted U-ohape, which carries a cutting die B, a forming die l and a. stripper B2. Above these parts are mounted a hollow 'cutting plunger B3 to co-act with the die B, and a forming plunger l'- to coact with the die B and by its further descent, after its forming action, to torce into a bottle the formed bottom which these dies have formed after cutting it from a strip C of paper stock. An endless belt, madev up of varound the bcd 'A'.

a series ot" hinge-connected plates D passcf-z through the arched die support A2 and It. is carried by pol ygonal pulleys D', D2., sipportcd by the trame, the former rotated step by step from a shaft D3 by means of a crank-plate Dt, pitman D5, crank DG mounted loosely upon the pulley shaft, and a pawl DT upon the crank and engaging a atchet wheel Dt'rigidlyeonnected with the pulley, the parts being so proportioned and adjusted that. each rotation ot.' the shat't D3 advances the belt. through a distance equal to the length ot one of its plates. 'lhe pulley D2 is looselyr mounted upon a crank or eccentric sli-att E mounted in brackets lil tixed to the frame and'itselt rotated by means ot' a hand lever E to move this pulley toward or away 'from its companion. lt is locked in desired position by a bolt E urged outward in a way in one bracket and into engagement in one of a series of apertmes in a disk E4 connected with the lever, 'by a spring The bolt may be disengaged at will by means of a. stud E lproject-ing from the bolt and sliding Each plate of the belt is intended to carry a` single bottle body l" and to stop momentarily with that body accurately in position beneath the forming and inserting plunger B4, which, during the momentary rest of the bottle, terms a bottom and t'orccs it into-tlmI open end ot' the bottle body.

For delivering one body to each belt plate, I provide a fixed chute Gr transverse to the plane of the belt and having one end in close proximity .to the pulley D.l The chute is downwardly inclined toward the pulley both in the direction olf its length and 'of its width. Open bottle bodies l" are delivered in this chute, vby the devices which torni them 0r otherwise, and owing` to. the double inclination they roll down with one end in close proximity to the belt, the foremost one being arrested, by the stop G', in the medial plane et the belt and with its axis approximately perpendicular ofthe belt plates. Each ot the latter bears,

v to the plane otono in perpendicular posit-ion, a rigid nearly semi-cylindrical forwardly concave wing D9, and the bottom ot the chute is cutl away to permit. these to pass. rlso-.prevent the. foremost body in the chutelfrom falling into this opening, the bottom bf the chute is prober A8.

cured.

vided with an upwardly swinging hinged arm 'G2 projecting, .along the middle of the opening, toward the pulley, and each wing is slotted at D19 so that it may not engage this arm in passing. At each advance of the belt,.a wing engages the foremost body and carries it forward, 4the remainder of those in the chute rolling down and bringinganother into position.

`As the bodies advance to the dies, the plates slide along the upper face of a rigid support A3 bolted to the bed A and of such height that each body, as it comes to rest directly beneath the dies, is at precisely the right height to have`a cup-like bottom forced into its open end bythe descending plunger, the thrust of which is supported by the mem- At this oint the plates pass between the guides 1", tion, and at the same held closely against the upright wing D by two light inclined springs A5, secured to the member A2, and which yield allowing the bottle and wing to pass between them when the belt again advances. These springs are preferably as shown, approximately equidistant from -the planes of the upperand lower ends of thewings, and the portions along which'each'bottle slides, in approachmg converge, so that the bottle when it comes to rest is gently but invariably held against both top and bottom of its wing, which is then accurately vertical, theplates being kept exactly horizontal bythe vfixed plane`A faced support A3', and also held exactly in the proper line of travel' by the guides A4. The part B insures erfect circular form of the bot-tles upper e ge, and thus the practically perfect registry of bottl-e and plun-L ger, which is indispensable with a high' speed machine using thin paper stock, is se- Aftcr receiving their'bottoms, the bottles are successively dlscharged as Athe wings pass arounl the pulley D2 andmay be received by paralining devices, not shown.

As ,this apparatus operates at somewhat high speedthere is danger that momentum of the. parts mayA prevent the bottle from registering with thedies with that accuracy which is essential, and for this reason a constantly acting friction brake is applied to the shaft of the lpulley D. As shown, this brake may be a simple strap H held against the shaft by a heavy weight I-I.

In the particular machine shown, the bot- ,tles are of such height as to contain a pint, but i-f itgbe desired to make with the same machine bottles containing a quart, the supv mitted to drag over the bed A", the pulley v I port A3 may be removed and the belt be perinsuring accurate locai time the bottle body is.

position beneath the plunger, constantly- D2 being moved outward by the lever E2 to compensate the loosening of the belt.

Vhat I claim is:

l. In apparatus'of the class described, thel -tles slide in passing to said devices constantly converging forwardly, substantially as set forth.

- 2. The combination with belt pulleys and an endless belt borne thereby and adapted to carry bottle bodies, of a. plunger adapted for forcing bottoms into bottles carried by the belt, means in line with the plunger for supporting the bottle-carrying fold of the belt, at different distances from the plunger,

vagainst the plungers thrust, and means for varying the separation of said pulleys to compensate changes in the position of the point of the folds support.

3. The combination with a bottle carrying belt provided with forwardly concave wings perpendicular to the belt, of an inclined chute transverse to the end portion of the path of said wings, cut away to allow thev wings to pass, and provided with a stop in.

positionto arrest the foremost body in the chute in the path of the wings, and an arm for supporting said foremost body in position, the'wings being slotted to pass said arm. A

4. The combination with a bottom inserting plunger, of an endless belt provided with forwardly concave wings for carrying bottle bodies beneath the plunger, springs below the plunger, projecting into the path of bottle bodies carried by the belt and between the planes of the upper and lower ends of said wings, and having the portions along which each bottle slides in approaching alinement with the plunger constantly converging, and means for advancing the belt step by step to bring the bodies to rest in `succession between said springs and in alinement with the plunger.

In testimony whereof I affix my signature in presence of two witnesses.
