GLUING-MACHINE FOR PAPER BOTTLES.

Specification of Letters Patent.

Patented Feb. 1, 1916.

Application filed. June 12, 1914. Serial No; 844,606.

To all whom it may concern:

Be it known that we, FRANK N. Wars and \VILLIAM C. WVEIS, citizens of the United States, residing at Monroe, in the county of Monroe and State of Michigan, have invented certain new and useful Improvements in Gluing-Machines for Paper Bot ties; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

Our invention relates to a machine for performing one of the steps in the manufacture of a box or bottle composed of paper, cardboard or the like, and is intended, more particularly, to rapidly and uniformly coat with glue or similar adhesive the surfacesof certain of the overlapping flaps of a boxblank. These flaps comprise the end of the box, as hereinafter described, it being understood that the side-edges of the blank have by a separate operation been previously secured together inoperative form.

Our invention also consists in details of construction hereinafter described and pointed out in the claims.

. Our invention consists of the devices, construction and arrangement of parts hereinafter described, and shown andillustrated in the accompanying drawings, in which Figure 1, is a front-elevation of our machine with one of the glue-pots hereinafter referred to shown in section; Fig. 2, a sideelevation of said machine with portions hereinafter referred to shown in section and showing the box-blank carrier hereinafter referred to in its initial position; Fig. 3, the same showing the box-blank carrier elevated to near the end of its upward travel;

Fig. l, a top-plan-view of the same with the box-blank carrier lowered as shown in Fig. 2; Fig. 5, a side-elevation of the lock-piece hereinafter referred to designed to retain the adjustment of the feed of the semiliquid adhesive, and Fig. 6, an end-view of the box-blank as it is fed into the machine.

Like numerals and letters of reference indicate like parts throughout the drawings.

In the drawings, 1 is a frame across the top, of which is journaled as at 2 a shaft 3.

This shaft carries a driving-pulley 4, and, if

desired, a loose-pulley 5 as a means for throwingthe machine into or out of opera tion. Upon the shaft 3 are fixed two gluerolls 6, the upper rear surfaces of which fit closely into and revolve in the front lower part of glue boxes 7 The glue-pots or boxes are open at their front for the reception of the rolls and have sides which overlap and fit closely against the ends of the rolls. The bottoms of the boxes 7 are forwardly and downwardly inclined and their sides have laterally projecting flanges 8 which engage and slide in guides 8 carried by the frame of the machine. The lower forward edge of the bottom of each of the boxes is adapted to contact with or to be moved away from the glue-roll any desired distance to either stop the flow of the glue or to permit its flow upon the side of the roll at such rate and in such quantity as may be desired. The position of each glue-box relatively to its roll is controlled by means of an adjusting screw 10 engaged with a stationary piece 1O carried by the frame and passing through a lug l0 projecting from the box. (See Figs. 2 and 3.) The lug 10 is engaged at opposite sides by shoulders or nuts on the screw 10 so that the inward. or outward movement of this screw imparts a corresponding movement of the glue-box toward or away from its roll.

99 are stop-screws located at opposite sides of the adjusting screw 10, each having a shoulder 11.

12 is a plate pivoted as at 13 upon the shank of screw 9 and having a notch 14 and a notchl5 in its lower edge. (See Fig. 5.) Assuming that the three screws 99 10 are set to permit exactly the required flow of the adhesive and that it becomes necessary to stop the machine, it will of course be also necessary to stop the flow of glue. To accomplish this, the screws 10 are set forward bringing the bottoms of the boxes into close contact with the glue-rolls. To reopen the glue orifices to exactly the proper adjustment, it is'only necessary to throw the piece 12 with its notches lle15 into engagement with the screws 9 -'10 and to withdraw the boxes by means of screws 10 until the pieces 12 contact with the shoulders ll on the screws 10. Now the boxes are stopped at their original adjustment, thus obviating the necessity for further experiment or test. Under some conditions it is desirable to apply pressure to the contents of the glue-pots. For this purpose we provide for each glue-pot a plunger 7 having a handle 7 and which moves with a working fit in a cylinder 7 open at top and bottom and connected with the chamber of the gluebox. The plunger is readily removable and: may be weighted as may be desired'to give the requisite pressure upon the semi-liquid lue.

b In Fig. 6 is illustrated a box having-its end-flaps unclosed. That form of our machine here illustrated is designed to coat with glue the inner surfacesexposed in the drawing-of the flaps a-b. In the completed box the surface a will adhere to the outer surface of the flaps 0 and the surface I) will adhere to the outer surface of the flaps a, thus forming a closely sealed three-ply end. The two rolls 6 are of the same width and of the same distance apart as the flaps ab. A bracket 16 is secured to the top of a frame 17 which slides vertically in guides or ways 18 secured to the front of the frame 1. Upon the top of the bracket is mounted a box 19, open at its ends and top, and arranged to slide horizontally inguides or ways 20 secured to the bracket 16. The box is provided with an adjusting stop-screw 21 which contacts with the outer end of the bracket 16 and limits the inward movement upon the flaps ab, it is necessary that-theseflaps be spread apart and in the same plane,

as shown in Fig. 6, and that the flaps c be "folded inwardly into the sameplane with the flaps aZ and out of the way. To accomplish this, we provide the devices now to 'be'described. 22-22 are a pair of thin metal plates of the same width as the flaps 0, pivoted together at their horizontal meeting edges, as at 23, upon the end of a horizontal rod 2% fixed in a cross-bar 25, .extendingbetween the side members of the frame 1. The

plates 22 are respectively pivotally connected by means of toggle-bars 26 with a block 27 which slides on the rod 24. A spring 28 pressing against the block 26 holds the block pressed normally forward so thatthe plates 22 flare toward the open mouth of the blank d and in horizontal alinement therewith.

Now when the box 19 is pushed forward carrying with it the blank d with its flaps projecting in frontof the box 19, the side flaps a-b are caught by the side margins of the plates 22 and are spread apart while the flaps flaps a-b apart and the flaps ctogether, all in a flat vertical plane, the plates 22 yielding tothis movement through the toggles 2627 and the spring 28. At aboutthe instant that the flaps ab have been positioned as just described, the box 19 containing the paper box is lifted vertically so that the exposed surface of the flaps a-Z) rub against the revolving gluey surfaces of the glue-rolls 6. This lifting of the box 19 is accomplished by means of the mechanism now to be described. 29 is a bar the lower-end of which is pivotally connected as at 30 with the vertically sliding frame 17, the upper end of the bar being pivotally connected as at 31 with the under side of the sliding box 19. 32 is a pawl pivotally connected as at 33 with the bar 29 and sliding horizontally in a sleeve 34 fixed between the side members of the sliding frame 17. 35lisa sprocket-chain-running upon an upper sprocket-wheel 36 and a lower sprocketwheel 37. The upper sprocket-wheel is fixed upon a shaft 38 which carries at its outer end a sprocketwheel 39 upon which runs. a sprocket-chain,

10 driven by a sprooketwheel 41 upon the shaft The sprocket-chain 35 carries at regularintervals lugs 12.

hen the box 19 is pushed inwardly,,as above described, the bar 29 is swung on-its lower pivot, thus forcing the inner endof the pawl 32 into the path of the upwardly travelinglugs 42 on the sprocket-chain 35. Now the first lug 42 which comes along catches'the :pawl, thus lifting the frame v17, carrying withit the bracket 16, the box 19 and the paper box. Thus the flaps a which are held" spread apart by the wings 22 until they reach the glue-rolls, are

moved upwardly ag l y h glue-rolls 6. To prevent the flaps a-"*- from adhering to the glue-rolls as the box 19 ascends, we providea small .roller 43' close to and above the glue-rolls, and

which holds the flaps away from the gluerolls after-the application of the glue. The" flaps a b having now been lifted to their uppermost point and having been brought in contact with the revolving glue-rolls, it becomes necessary to retractthe box 19 and to permit the parts to resume their initial position, ready for a repetition of'the operations thus fardescribed. To this end we provide the following devices: Upon the bar 29 is journaled a roller 44 which, when the box 19 is pushed inwardly to its limit, assumes the position shown by the adjacent dotted line. Asthe frame 17 with its burden clined surface of the piece 45, thus swinging the bar 29 outwardly carrying with it at-its I upper end the box 19. and at the same time pulling the pawl 32 out of-enga-gement with that lug 42. with whichv it happens to be-in I engagement. The frame 17 with its ap.- pendages immediately drop to their original position. To prevent undue noise, jar or concussion from the fall of the frame 17 we provide a dash-pot 46 having a piston 47 connected by rod 48 with the lower end of the frame 17, operating in the usual manner. When the pawl 32 is tripped from lug 42 the box 19 has not been withdrawn upon its bracket the requisite distance for the reception of a box cl. To obviate this we provide a bar 49, pivoted at its lower end, as at 50, on a bracket 51, secured to one of the guides 18 and in the path of the roller 44. The pivot or shaft-piece 50 carries, rigid therewith, an arm 52 which at its upper end is connected by means of spring 53 with the frame of the machine in such manner that the bar 49 is held normally pressed inwardly at its top. Now as the roller 44 ascends, it traverses the inner edge of the bar 49 which yields to the upward movement of the roller. When the roller 44 has passed above the upper end of the bar 49 the bar, thus released, springs inwardly so that the roller in its descent traverses the outwardly inclined outer edge of the bar, thus swinging the upper end of the bar 29 outwardly the required distance. The parts are thus restored to their initial position. The box 41 is now removed from the holder 19, and the machine is ready for a repetition ofthe above described operation. It will be seen that when the flaps ab move upwardly out of contact with the plates 22, these plates, under the pressure of spring 28 will, unless v prevented, swing upon their pivots into the path of the falling flaps a?). To obviate this we provide a plate 54 having a limited sliding movement upon the frame of the machine and held,normally elevated by a spring 55. The plate has rigidly connected thereto an inwardly projecting finger 56. lVhen the box-blank carrier 19 is at its lowermost position it strikes and holds depressed the plate 54 with its fingers 56, as in Fig. 2. Then the carrier moves upwardly the plate 54 is released and is moved by its spring upwardly with the inner end of the finger 56 touching the lower plate 23. Now both of the plates are held in the same vertical plane, as in Fig. 3, until they are released by the fall of the carrier 19 upon the plate 54.
