PAPER-BAG MACHINE.

SPECIFICATION forming part of Letters Patent No. 405,308, dated'J' une 18, 1889. Application led August 13, 1888. Serial No. 282,549. (No model.)

To a/ZZ whom it may concern: y

Beit known that I, ALBERT C. GETTEN, a citizen of the United States, residingat Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Paper-Bag Machines, of which I do declare the following to bea full, clear, and exact description, reference being had to the accompanying drawings, forming part of ro this' specification. v

A great desideratum with retail dealers and other users of paper-bags is some means whereby the mass or package of bags can be conveniently held in such manner and posii 5 tion that single bagsy can be quickly taken therefrom without disarranging the package.

Appreciating this need, my present inventionhas for its object to provide a paper-bag ma.

chine with means whereby the bags, as they 2o pass in finished condition from the machine, shall each be furnished, at the same point with respect to and adjacent` its open end, with a perforation or eut-away space, so that after thebags have been hunched together these perforations 'will be coincident, in order to permit a suitable sustaining cord, rod, or wire Jrobe passed through the perforations tov conveniently hold a number of bags together and yet allow one or more to' be readily re- 3o moved without disarranging the' others.

To this endmy invention consists in the novel features of construction hereinafter decribed, illustrated in the accompanyingdrawings, and particularly ydefined in the claims at the end of this specification.

' In the annexed drawings my invenhion is, for convenience,illustrated in connection with a paper-bag machine of the type illustrated in Letters Patent granted to C. B. Stillwell,

,o 'September 20, 1887, and numbered 370,099;

but it will be readily understood that it is applicable also to a variety of other machines.

Figure 1 is a plan view of ya portion of a paper-bag machine having my invention ap plied thereto. Fig. 2 is a View in vertical longitudinal section 0n line 2 2 of Fig. 1. Fig. 3 is a View of a portion of the former detached. Fig. 4. is a perspective View of a finished bag,

showing the preferred location of the perfora- Y 5o tion. Fig. 5 is a viewl in vertical -transverse section on line 5 5 of Fig. 1. Fig. 6 isan enlarged view, in vertical transverse section, on

line 6 6 of Fig. 5. g v A designates the main frame of the machine, above the table or bed B of which is sustained the former C, which, in conjunction with the forming disks or wheels D, serves to fold the web of paper lengthwise as it passes tothe final folding apparatus. (Not shown.)

'The former C extends between the feed-rolls 6c E and E', and its serrated edge terminates slightly beyond 'the fixed cutting-blade F, and with this blade and the rotary cutting-blade or striker G co operates in severing 'thel folded tube into-suitable lengths to form the 6g finished bags. The shaft G Iof the cuttingblade or striker extends obliquely across and beneath the bed of the machine and receives its rotation from the miter gear-wheel g,^the speed of which,ischangedaccording as it is 7c desired to vary the length of the bags.

The general construction and operation of the parts as thus far defined, and aswell also their co-operation Withthe parts of the machine that have not been shown, are well un- 7 5 derstood by-those familiar with vthis class of apparatus. f

The web of paper is by means of the former C vand'y forming-rolls `D folded into proper tubular shape to form a bellows-sidedv bag, 8o and the folded .tube is severed' into proper bag-lengths by the fixed and rotary cuttingblades and the serrated end of the former.

In order to provide each'bag near its top with a perforation, througliwhich acord,rod, or wire may be passed, I preferably employ a `punching mechanism consisting of rotary male and female dies. In the construction shown the male die His mounted upon a shaft I, held in bearings h above the table 9o and the former C, and the ,female die H is mounted on the shaft I', that is sustained by hangers J and J depending fron. the under side of the table and attached to the main frame, respectively. The shafts I'and I' are 95 geared together, as shown, -and are in gear with the rotary cutting-blade or striker, the speed of which'with respect to the feed-rolls determines the lengths of the bags. I prefer to gear the shaft I with the oblique shaft of roo the rotary cutting-blade or striker and to employ for this purpose sui-table bevel-

pinions

2 and 3, fixed, respectively, to these shafts.

My purpose in gearing the punchingmechanism with the striker is to insure the accurate perforation of the paper adjacent the edge of theparts that are to form the open ends of the bags, and it will be seen that when the operation of the dies is once properly adjusted with respect to the striker G the dies will continue to perfor-ate the paper at the proper points, it being only necessary to adjust'the movement of the dies with respect to the striker when the speed of the latter is changed to form particular lengths of bags. This timing of the action of the dies with respect to the striker can be readily effected by the adjustment of the bevel-pinion 2 upon the shaft I (this pinion being adjustably held on the shaft by means of a setscrew) until the striker and the dies operate upon the paper at the proper relative times.

In order to enable the dies H and H to coact in perforating the paper, I provide the former C with a suitable space`as, for eX- ample, is shown at c-through which the dies can meet. This space c is preferably formed at such point andthe dies Hand II are preferably so placed that the perforation of the paper shall occur through the body and between the foldedsides of. the tube and at one side of the pasted seam or lap, as seen inFig. l of the drawings. so placing'the dies that 'they hall cut the paper atone side of the pasted seam or lap is not merely to avoid cutting through more than two thicknesses of paper, but also to avoid cutting through the paste and wet paper, which would interfere with the most effective action of the dies. My object, also, in so setting the female die II that it shall project through the former C in the punching operation is to avoid all danger of stretching or separating the freshly-pasted seam of the folded tube, as would be apt to occur if the upper side ofthe tube were depressed in the punching operation.

In the particular form of .punching mecl1- anism shown, the shaft I, on which the male -die is mounted, is provided with a hole 4, ex-

tending through it, and with an offset 5, in which hole and offset the die H isheld by means of a seat-block 6, threaded to engage with the threaded lower portion of the die. in thus threading ,the rear portion of the' male die is to enable the die' to be readily adjusted from time to time tocompensate for wear. Around the die I-I, I also prefer to`place a rubber block 7, to enable the die to more certainly clear the paper after the perforation has been made therein. The shaft I', that carvries the female die II', is shownA as provided with a disk`8, through which and the vshaft passes the transverse hole 9,- fromwhich the -pieces punched out of the paper can readily 'falL It will be observed that the female die pro My purpose in My object the paper downward through the cutaway space of the former. It will be understood, however, that while I have described what I regard as the preferred form of punching mechanism, the precise details of construction may be varied within wide limits without departing from the spirit of my invention.

From the foregoing description it Will be seen that 'as the web of paper folded in the direction of its length is fed forward between the diesll and Il', the perforation of the paper will be effected, and the movement of these dies will be so timed Awith respect to the rotation of the cutting-blade or striker that the perforation of the paper will occur at a point adjacent the line of cut of the cutting-blade or striker and consequently adjacent the` open end of each bag. One advantage incident to so gearing thepunchin g mechanism that its movements shall correspond with that of the cutting mechanism is that a proper perforation of the paper adjacent the line of cut subsequently made is thereby gearing the punching mechanism is that the perforation of the paper is made while itis still in the web, whereas, if attempt were made to effect the punching after the baglengths had been cut, there would be serious danger of inaccuracy occurring'in the position of the perforations, since in the final folding operations a slight variation in the movement of the severed lengths is of frequent occur rence.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a paper-bag machine, the combination, with suitable rolls for feeding the web of paper, a suitable former for folding the same, and a knife for cutting it into bag-lengths, of a punch for perforating the paper, said punch being located in position to perforate the paper adjacent, but entirely at one side of the line of the top edge of each bag,`substantially as described.

2. In a paper-bag machine, the combinan tion, with suitable rolls for feeding the web of paper, a suit-able mechanism for folding said web-such as a former `having a cut-away l space-and aknife or striker for cutting the web into bag-lengths, of male and female dies located, respectively, on opposite sides of the former adjacent its cut-away space, and located, also, in position to perforate the pa'- per adjacent, but entirely at one side of the top edge' of each bag, substantially as described.

3. In a paper-'bag machine, the combination,with suitable mechanism for feedinga web of paper, of a former for folding said web, said former having a cut-away space, a female die locat-ed on one side of said former, a male die located` on the opposite side of said former, shafts for said dies, and a cuttingblade in gear with said shafts, substantially as described.
