Specification forming part of Letters Patent No. 122,099, dated December 26, 1871 Reissue No, 82524, datedv July l29,1879 3 application filed June 11, 1879. l

To au whom itA may concern v Be it'lknown that I, JAMES ARKELL, of Ganajoharie,` in the county of Montgomery and State of New, York, have invented certain new and .useful Improvements in Paper-Bag' Machines; and I (lo-hereby declare the following to be a full, clear, and exact` description thereof, reference being had to the accom-v panying drawings, making part of this specification, and to the letters of reference marked. thereon.

As is well known to those skilled in the art,

the bags or sacks are usually made from a roll lof material which is passed over a suitable former and has its edges pasted together, so

as to be delivered from said former n the shape ofa flattened tube, Which'is cut up into suitable lengths or short tubes, each of which may have one end cut and creased or partially folded in a peculiar manner to facilitate the next subsequent operation of forming the bottom.

To this operation of forming the bottom 'of the bag by pasti-ng and folding over the matethe mode of operation is such that the partially-formed sack, or the preparedsack-body, is carried automatically through the machine ona carrier or bed which moves always in the same direction, and on which it is successiveiy subjected to the operations of mechanisms or devices for applying the paste and making the folds to finish the bag-bottom, as will be hereinafter more fully explained; and y inven tion fu'rthericonsists in certainnove f' combinations? :of devices for performing' the several operations bywhch the bag-bottom is com pleted, as will `be hereinafter more fully explained; L A l To enable' those skilled in the art to make and use myiinvention, I will proceed to more fully'describe'it, referring by letters tothe aci colnpanyingdrawings.4 which makepart of this specification, and in vvhic: the diagramsNos.

" 1, 2, 3, 4, and 5 illustrate the different condi'-v tions of the bag during its manufacture, as I will presently `more fully explain, and in which the Figures 1, 2, 3, 4, 5, and 6'are,respectively, a -front elevation, side view, side. elevation,ver vtical section, skeleton View ofgriping mechmachine is designated by the same letter of reference.

In orderthatthe specification of the machine maybe more readily understood, I Will, before describing its construction and operation, prooperationsfand'e'ects which the machine is passed through the said machine.,

Itis iounted on a shaft, d, which turns in suitable bearing-'boxes in lthe infin frame A, and which is driven by means of a y spur-sector, e, that is'keyedv fast thereon, and

which is-made to periodically engage with, and

lbe once rotated by, the main gear E, in thev ,following manner: Atappet-arm,t", (see Figs. -1 and 2,) is secured' to said shaft d in such a manner that when the lspur-sector e, shaft d, v and paster I are in their non-operative positions said tappet-arm'will depend about vertically from said shaft; and on the ini-.er side` of Athe rim of the main gear E is alatera-llyprojecting pin or stud, p, which, once during each revolution of said gear, strikes the said tappet-armvand 'vibrates `it far enough. Vto so turn the shaft d and its sector e as to bring the teeth of theA latter into full engagement with those of said gear E. The said gear then causes 'saidfseetor e, t'o make almost an entire revolution, when the latter runs ont of engagement with the former, and again comes toits y'non-operativek position and a state of rest,

leaving .the tappetarm't" in a position to be again struck at the next revolution of gear E to produce arepetition of the desired move-` ment ofthe shaft d, in the manner first eX- plained; and this periodical rotative moveinent of saidfshaft; d causes the desired movements of the paster I, presently explained.

fis a disk, fast on shaft d. This disk has a notchin its edge or face, into which catches the bent end of a retaining bar or arm, g, piv.- Ao'ted tothe frame A; and said bar g is at intervals drawn back (to release the disk f) by means of a cam, h, on the shaft F.

Thereg'is'ter fingers or stops a, a are secured at their upper ends to a roch-shaft, i, which is moved, through the medium of a crank. j, and bar 7c, by the cam J on shaft F.

On the main driving-shaft B are secured the ereasers K and 1,(the.operation of which will v be presently explained,') andvalso a; pulley, L

from which latter passes a belt, l, to the pnlry m, which latter, together with pulley n, is fast on or part of a sleeve or hollow shaft, o, that turns freely on the shaft M, and on which .-is secured a frame, N, that carries the counter or short shaft O.

The V,shaft M is mounted in suitable bear- K ings inf the frame A, and is periodically rocked or oseillatedthrongh the medium oferank p and rod q, by a cam, 1)', on the shaft F, and on the shaft O are mounted four paste-wheels, l 2 3 4, which are kept supplied in any suitalble manner-from areservoir, (not shown-J and "the face of the drum or carrier G.

from the peripheries of which paste is supplied to the bag-bottom.

y Q Q are griper ngers or dogs, which clasp or hold themouth end of the bag securely ou back and forth in slots in the face of said drum, and are operated by means and in the 'manner I will now explain, viz: Said fingers are fast on a rock-shaft, r',fwhich, as seen, is mounted in suitable boxes on the internal face of the' rim of drum G; and on one end of Asaid shaft is secured a ;.hoe-piece',s, from which eX- tends a rod, t, provided with 'aspiral spring,

u, and passing through a stand, '0, (see Fig. 5,) and so arranged that the tendency of said spring-rod attachment is to hohl the shoe-piece in either of the two positions in which it may be placed, (these two positions being those which the rock-shaft i' assumes when the iingers Q are either drawn' in or thrown out to clasp the bag.) This shoe-piece s is formedwith two cam-like depressions, in which Work alternately (as said shoe travels around with the carrier-drum or cylinder) two rolls or caster-wheels, 5 and 6, which are mounted in little stands R that are bolted to and project from the main frame IA, as seen; and as the shoe-piece s travels along and is struck by rst one and their the other of the wheels 5 and 6, it is oscillated in first one and then the other direction, and so rocks the shaft as to alternately throw'v the said fingers ont to clasp and carry in a bag, and to release it when finished and passingto the discharging mechanism.

The pulleys A B', mounted on shafts G D', as shown, together ,with the cords Orba-nds b @passing around them, as seen,'lead off and discharge the finished bags under the table on which the attendant places thework to be fed to the machine. p

a are the folding arms or blades which effect thelast fold of thebag-bottom. They, f

like the gri per-iin gers Q, are protrude'd through the faceof thecylinder or drum, and are Worked from a rock-shaft by mechanism and in a manner similar to that just described in connection with said fingers Q, the only dilferencein operation being that, while lthe ngers Q are short and are so arranged that only their ex-` treme ends protrude and clasp theedge of the y mouth of the bag, the blades f t' are long and are so arranged that 'their axes .'of motion shall be about coincident with the line in which occurs that fold in the bag-bottoinwhich theseblades press down. f

bb are folding armsor sweeps, which gather up and foldover the stock to form the tirstfold made in the bottom-forming operation of the '4 They are'mouuted on short shafts or studs c', that turn in stands secured to the machine.

ri m'of the drum, vand which are provided with pinions d', which mesh into sectors e. These sectors are each provided with-an arm, f', (see Fig. 6,) and to these arms is connected'a bar,

g', which is held in one direction by a spring, h', and is forced at intervals in the opposite direction by means of acamlplate, F-, which presses against a roll or caster, i', in the end of said bar g', and by the alternate movements end' Vwise of the said bar in opposite directions the sectors c `are worked, and from them, through rthe medium of pihions d', the folders b b are operated.

After what has been said of thedetailed construction' and operation of parts, the following explanation of the general operation of the machine will be readily' understood.

Motive power being applied to the main shaft, and the machine thus putin motion,the prepared stock or partially-formed bags, in the condition seen at diagram No. l, are fed from the table (with their mouths or open ends toward the machine) against the stop-fingers a. a, and there allowed by the attendant to rest until the gripcr-fingers come along and carry each bag along on the face of the drum or cylinder Gr, the stopllingersa 'a being automatically lifted by the means already described to permit said griper-fingers to carry .off the blank.

When arrived at the proper position the paster I, which by this time has begun to make one of its periodical movements, comes in contact with the material and puts a coating of paste along the edge at Vp, (see Diagram 2.) and then the paste-wheels I 2 3 4 move up and apply the paste in four lines, as seen at p2, Diagram As the bag is carried on, the'edge of c1easer"'I""co1nes up and indcnts the-material at the line .fr x, Diagram 3, while at the sametime the folders b b' gather up and fold over the stock, as shown at Diagram No. 3, and as thebag further progresses with the drum 'G the creaser K comes up and indents the material at yy, and, holding it while thefoldcrs a come ont, passes ont of contactrtherewith, and the said folders then fold the stock over into the shape seenat Diagram No. 4., which completes the bag, which then passes on and is discharged between the cords b b and wheels A D' in a iinished state.

When the bag, with its bottom thus pasted and folded, is opened ont or filled, it presents about the shape seen at Diagram No. 5.

It will bc seen that by applying the paste as shown there is no danger of any ol' the bottom portions getting stuck to those portions of the sides which have necessarily to rest in contact with theinner surfaces of the bottom parts while the latter are being pasted and folded. y

In conclusion, I would slate I do not limit myself to the precise details of construction herein shown and described, as the same may in some respects be varied without departure from the principle of my invention, and I wish to be understood as including herein the mechanical equivalents of the devices hereinbefore described, especially as regards the means of folding.

Having so fully described my new machine for pasting and folding the bottoms of satchelbottom bags as to enable one skilled in the art to fully understand and practice my invention., What Il claim herein is-, s

1. In a machine for pasting and folding bagbottoms, the combination, with a drum or carrier that moves in one direction only, of'pasting and folding mechanisms arranged and operating to successively paste and fold, by one forward and one backward fold, the last two rests on the4 surface of said carrier, substantially as set forth.

2. In a machine for forming the bottoms of satc'b el.bottom bags, the combination, vwith the drum or carrier on which the blank'is held, of a creaser, I', for creasing or indeutin g the maLv terial at theline on which one of the flaps is to be turned down, and folders b', arranged and operating to fold such flap over and down, 'substantially as set forth. y

3. In a machine for forming the bottoms of satchelbo'ttom bags, the combination, withrthe a 'creased K, for creasing or indenting the -material at the line on which the other of the flaps is to be turned down, and folders a', arranged sition the last folded flap, substantially as set forth. v

4. The combination, with a drum or carrier which moves in one direction only, of pasting,

and operating to apply paste to the last folded pair of flaps', crease the material at the lines the said flaps. down, all 'substantially as set forth.

5. The rotary paste-wheels, arranged to autom'atiealljT move up to and away from the sack-supporting drum or carrier, in combination with the automatically and intermit tently rotatingpaster and the said moving carrior, the whole arranged to operate subtanti ally set forth. i

In witness whereof I have hereunto set my hand and sea-l this 19th day of May, 1879.
