ANDREV H. vFIALA, OF NEW YORK, N. Y., ASSIGNOR TO THE UNION PAPER BAG MACHINE COMPANY, OF PHILADELPHIA, PENNSYLVANIA.
PAPER-BAG MACHINE.
SPECIFICATION forming part of Letters Patent No. 439,058, dated October 21, 1890. Application filed February 27, 1890. Serial No. 341,971. (No model.) Y
To all whom, it may concern:
Be it known that I, ANDREW H. FIALA, of the city and county of New York, State of New York, have invented a new and useful Improved Paper-Bag Machine, of which the following is a true and exact description, refence being had to the accompanying drawings, which form a part of this specification.
My invention relates to machinery for mak- Io ing paper bags, and particularly to machinery adapted to make paper bags from bellowsfolded tubes and by severing such tubes into bag-blanks, and then completing the bag by turning up and pasting one end of the blank so as to close it.
The object of my invention is to provide a machine of simple and compact construction, and one which can be easily adjusted and operated and readily adapted to make differzo ent sizes of bags.
The nature of my invention will be best understood as described in connection with the attached drawings, which illustrate a paper-bag machine constructed in accordance z 5 with it, and in which Figure lis a plan view; Fig. 2, a side elevation; Fig. 3, a side elevation on the sectionline cc of Fig. I; Figs. 4L, 5, and 6, cross-sectional views taken through the paste-roll and 3o its attached and coacting mechanisms, showing the way in which the said devices Operate in the manufacture of the bags. Fig. '7 is a cross-section taken on the line y y of Fig. l; Fig. 8, alongitudinal section taken on the line 3 5 z a of Fig. l; Fig. 9, an enlarged cross-sectional view of the three knife-blades used in severing the tube into blanks, and Fig. l0 a perspective View of the end of a tube or of a y blank after it has been severed by the knives (o shown in Fig. 9.
The parts of the machine shown in the vdrawings are those which operate upon the bellows-folded blank after it has been formed. The tube-forming mechanism may be of any usual kind and is not shown in the drawings.
A indicates a tongue or extension from the former-plate,around which the tube is formed; a, a tongue extending between the recessed feed-rolls C and D', and A a knife sustained and held by the said tongue a.
B B, &c., indicates the frame of the machine.
C is the shaft on which the lower feed-roll C is secured, and on the end of which are secured gear-wheels c c.
Dis the shaft on which the upper feed-roll D is secured. Said shaft is j ournaledin blocks or arms D2 D2, which are pivoted to a shaft D3, so thatthesaid j ournal-blocks, carrying the roll D with them, can be thrown up and backward when it is desired to adjust the paper Vin place or to remove the'upper feed-roll for any other purpose. A brace D6 connects the pivoted journal-blocks, and to it is attached a rod D4, upon which a Weight D5 is adjustably connected. By moving this weight the degree of pressure with which the upper feedroll shall bear upon the tube passing between the feed-rolls can be nicely regulated. Upon the end of the shaft Dis securedagear-Wheel d of the same size as the gear-wheel c upon shaft C. Then the roll D is in operative position, these gear-wheels are engaged, and the upper roll is thus driven at the same speed as the lower roll.
E is the main driving-shaft, to which is attached the drivin g-pulley E', by which motion is communicated to it and a gear e, which engages and drives the gear-Wheel c. Apul- -ley E3 is also attached to shaft E, and by means of belts E2 and W2, connecting with an intermediate pulley E4, the pressure-rolls U W at the end of the machine are driven by it.
Besides the knife A', attached to the tongue c, I also secure to the frame of the machine a knife S, situated so that its cutting-edge will cut a little in front of the edge of knife A', and above these knives I secure a cutter roll or shaft T', to which a cutter. or knife T is attached. All of these knives have serrated edges, and the knife T is adjusted so that its teeth will pass between the teeth of the knives A and S. (See Fig. 9.) The action of these sides, passes' above the knife A', and is sev` ered, as is indicated at y, by the coaction of the knives A' and T. The lower ply of the paper is then severed, as is indicated at y', by the coaction of the knives S and T, and the knife S being in advance of the knife A the lower ply is severed on a line in advance of the first cut, so as to form a projeetinglap, to which paste is applied in the manner hereinafter described, and which is then folded up and pasted down upon the upper ply of the blank.
It is important that the action of the knife T should be quick at the times when it is coacting with the stationaryknives in severing the blank, and in order to obtain this quick action I secure upon the shaft T an elliptic gear-wheel T2 and upon a driving-shaft H a similar elliptic gear-wheelT3, (see Fig. 2,) arranging them, as shown, so that the portion of the wheel T3 having the longest radius, shall engage aportion of the wheel T2 having the shortest radius at the time when the cutting operation is being performed, the shaft T, of course, moving With varying speed and in the way which is well understood in connection with elliptic gears of the kind shown.
F isa stud adj ustably secured to the frame. As shown,it is secured in a slot G, lying in a planev which passes through the center of shaft H. To the stud F is secured a gearwheelf, which engages the gear-wheel c on shaft C, and also a gear-wheel h', secured on shaft H.
H is a roll secured to shaft H, J a shaft situated in the rear of shaft H, and J a roll secured to shaft J.
I is a beltor apron, formed of some elastic material-such as rubber-and running' over j jfrom sticking to the pasting-roll and being icarred up, I secure to the outside of roll K3 the rolls H' and J', as shown. In place of this construction the elastic apron I might be secured around the periphery of a roll I-I'; but I prefer to make it run on' the two rolls, as shown.` In addition to the gear-wheel 7L', another gear-wheel h is also secured to shaft H, which engages a gear-wheel k, attached to the shaft IQ which actuates the paste-cylinder K3.. The other end of this paste cylinder has a hollow shaft K' journaled in the frame of the machine, in the end of which an orifice K2 is formed in line with apaste-supply tube M. (See Fig. 8.)
M' is the paste-reservoir, situated onV the top'of pipe M, and 'm a cock, situated in pipe M, and by which the paste supplied to the roll through its hollow shaft is regulated. The paste-roll K2 is eccentrically secured to the shafts or journals at its ends and is slotted, as shown, at K4, and in this slot a pasting-roll N,journaled at each end-of the pasteroll K3, revolves7 said roll having a light 1 groove formed in it, as shown at n.
K5 isa plate, which is screwed onto the side of the slot, and pressing against theroll N it prevents the paste from escaping -from the paste-trough. Mechanism is of course con- 4ings being attached to the roll-K3. end of this shaft Q', I attach an arm Q4, car-A ;rying a roller q at its end, said roller run.- ningaround a catnR, which normally keeps "it pressed out and the plate in position with reference to roll K3, as indicated inFigA. A `depression o" is formed in cam R, which permits the arm Q4 to move inward, as shown in Fig. 6, this inward mot-ion occurring immedifately after the creasing and pasting has been' effected, and resulting in throwing the plate `Q2 downward, as is shown in Fig. 6, solas to iprevent the blank from being raised offof the apron I.
nected with the shaft or bearing of roll N, so
as to rotate it and cause its groove n, carrying a line of paste, to come to the desired positionat the desired time. As shown in the drawings, I accomplish this by the device best shown in Figs. 7 and S. Around the hollow shaft K', I secure a sleeve P2, having formed or secured to it a ratchet p2 and a gear-wheel p2. The sleeve turns freely upon the shaft K', and is held in place by means of a pawl p4, attached to some stationary portion of the frame. To the end of the shaft N of pasteroll N, I secure a gear-wheel p, which is engaged so as to be driven by gear 192 in any convenient Way, as by an idler-gear p', journaled on the end of the paste-roll. The operation of this device is easily followed. The sleeve P2 and its gear-wheel p2 are held stationary by the pawl p4, and the roll K3 revolving the idler-roll p', which engages gear p2, revolves on its bearing and in turn revolves gearwheel @which turns the pasting-roll Y. The adjustment of this mechanism is easily effected by turning the sleeve P2, by which means the paste-carrying slot of the pastingvroll is made to come into play on anydesired line as the pasteroll K3 revolves,.changes of ycourse being necessary from time to time as bags of different size are being made. A little in the rear of the pasting-roll N, I secure to the outside of the paste-roll Ka creasingblade O, which engages the blank on the line In order to prevent the end of the blank a plate Q2, which, as shown, is. secured to a shaft Q', journaled in bearingsq, said bear- To the Q3 is a spring arranged to keep the camroller q always inzcontact with the surface of the cam R.
As I have already noted, the machineis rgeared so that a cutting device is directly connected and actuated by the mechanism which `creases and applies paste to the bag-blanks.
Consequently any increase or diminution of the speed with which the :rolls I-I' and Ksturn IOO IIO
is accompanied bya similar increase ordiminution in the speed with which the knife T moves and the relative action of theV parts always remains the same. The adjustment of the machine to bags of different size is effected by changing the idler-gear f and of course adjusting the spindle F to correspond with the idler-gear used. It will be seen that by putting a smaller gear on spindle F the action of the knife T will be hastened and shorter blanks cut from the tube, and by putting a larger gear upon spindle F the action of the knife will be made slower and longer blanks cut from the tube; but in either `case the creasing and application of paste will be made at the proper time for the new size of blank.
Referring now to the end of the machine, W' and U' are presser-rolls secured to shafts W and U3. The shaft W is driven by means of belt W3, and has upon it a gear-Wheel w, which engages a gear-wheel u on shaft U2 and drives it with a corresponding speed. Pivoted to shaft U2 are arms U3 U3, in the ends of which is journaled a roll U, the arms being braced by a cross-bar U5 and a spring U3, attached to said cross-bar and arranged so as to draw the roll U down into close contact with the elastic apron I and above the roll J',
around which said apron passes. Around the rolls U' and U are secured tapes U4; or, of course, an apron may be used in place of tapes. The construction described, by which the roll U is secured on the pivoted arms U3, is advantageous, because it enables the said rolls and arms to be thrown up out of the way, enabling the operator to get at the lower parts of the machines and to arrange the blanks upon them. A
The action of the above described parts is as follows: The blank having been creased and pasted is fed along upon the apron Iwith its creased ends standing up, as shown in Fig. 6, and this end coming in contact with rollU is bent back, overlying the upper side of the blank, and then carried along over table V betweenv the presser-rolls W' U', which press down the pasted seam and complete the bag.
I believe that the construction of the machine as shown in the drawings will be found best adapted for practical use; but it will be understood that many of my improved devices are capable of independent as well as conjoint use, and I do not wish to be linderstood as limiting my claims on the presence of any elements of the machine shown and described, except those specifically referred to in them.
Having now described my invention, what I claim as new, and desire to Vsecure by Letters Patent, is
