PAPER-BAG MACHINE.
SPECIFICATION forming part of Letters Patent No. 626,369, dated June 6, 1899.
Application filed March 22, 1898.
To aZZ whom it may concern.
Be it known that I, J USTUS DOERING, a citizen of the United States of America, residing in the city and county of Philadelphia, in the State of Pennsylvania, have invented a certain new and useful Improvement in Paper- Bag Machines, of which the following isatrue and exact description, reference being had to the accompanying drawings, which form a part hereof.
Myinvention relates particularly to that class of paper-bag machines which are adapted to make what is generally known as the satchel bottomed bellows folded paper bag, and the object of my invention is to provide a simple mechanism whereby such bags may be made with great rapidity and at the same time without unduly rapid movements of operative parts of the machine.
The nature of my improvements will be best understood as described in connection with the drawings, in which they areillustrated, and in which- Figure 1 is a plan view of-a machine embodying myinvention; Fig. 2, a longitudinal section taken as on the line 1 l of Fig. 1; Fig. 3, a cross-section taken as on the line 2 2 of Fig. 4: is a plan view of a portion of the mechanism on an enlarged scale; Fig. 5, a similar enlarged view of the same portion of the mechanism shown in elevation. Fig. 6 is a perspective view illustrating another detail of construction; Fig. 7, a cross-sectional view taken as on the line 4 at of Fig. 6; Figs. 8 and 9, plan views showing the operation of the folding-blades upon the bellowsfolded paper tube; Fig. '10, a front view taken as on the section-line 5 5 of Fig. 8, showing the engagement of the folding-blades with the tube; and Fig. 11, a detail showing the nipper by which the paper tubes are grasped to the apron.
A indicates the frame of the machine, upon which, as shown, are mounted the shafts B and 13, each carrying chain orsprocket wheels, as indicated at B B and one, the shaft B, as shown in the drawings, being provided with fast and loose pulleys, as indicated at B and 13 C 0 indicate guides arranged between the sprocket-wheels and serving to support the Serial No. 674,758. (No model.)
apron, to be hereinafter described, as it passes through the operative portion of its travel.
D D indicate chains formed of pivot+links arranged to pass over and engage with the sprocket-wheels B" B and supporting the plates D'D, making up the apron ofthe ma chine, and upon which apron the blanks to be operated upon are delivered and to which apron the devices for operating upon the blanks are secured. At regular intervals, somewhat in excess of the length of a bagblank, the plates D are perforated, as indi cated at D and provided with nippers E, which, as shown, are secured on levers E, fastened to rock-shafts E which rock-shafts are provided with springs E which normally hold the nippers closed down, as indicated in Fig. 11. The shafts E are also provided with lever-arms E, which as the belt travels come first in contact with a pin M, which opens the jaw and enables it to engage the front end of a bag-blank to be operated upon, the said levers E coming next in contact with a pin M, which again opens the nipper, releasing its hold upon the bag-blank. Secured to the apron and somewhat in the rear of each nipper E are the pivot-pins F F, one pair lying upon each side of the portion of the apron upon which the blank rests, and upon these pins are pivoted the folding-blade frames, (indicated at F Ft) the portion F being slotted, as indicated at f, and traversed by the pivot-pin F having its bearingin the frame,- and, as shown, a head f, to which the movable blades G are attached.
G is a fixed foldingblade, which is rigidly fastened to the portion F of the frame, as indicated at g g.
G is movable folding-blade having in that part which comes in contact with the paper blank a substantially identical form with that of the blade G, and (l is another movable folding-blade lying in normal position above the blade G and intended to lie upon the top of the tube-blank and to define a line of fold about which the blank is opened. Both of the blades G and G3 are fastened to thehead f of the shaft F and a spring, such as that indicated at F, normally holds the blades in the position indicated in Figs. 4. and 5.
G is a supplemental or gripping blade pivoted on the-rearedge of the blade G bybeing.
fastened to' a' sh aft whichhasitsbearings in 7 the standards H H, said standards projecting,
as shown, from the face of blades G, and which shaft is acted upon by a spring H so asr to' normally keep the gripper blade- G?- pressed down upon the blade G.
9 indicates a heel extension of'the nipper G extending up substantially at right angles to the blade.
F is a standard extending up from the plate D, to which the pivot-pin F is secured, and
- having extendingfrom it the bar F which. in the retracted position of the frame lies in front of the heel extension 9 andinsuchposition that as the frame is swung forward it opens the nipper by 'acting onthis-heel ex? tens-ion and'releases its hold, permittingxthe nipper G to close when the folders have come to operative position, as indicated at:the ends iii-'Figlili ,F jis-apost'orstandard extending up fromtirefra-me-F F asshown, and'carryinga rol ler F on*its end-in position to be acted on I-an'd'l' are lever-arms secured to'the shaft' F and anglin gt to' each other preferably, as shown, slightly-over ninetydegrees. t and 11 f are'rol l ers secured on -these levers.-
