PAPER-BAG MACHINE.
SPECIFICATION forming part of Letters Patent No. 722,986, dated March 17, 1903.
Application filed August 6. 1902. Serial No. 118.610. (No model.)
' To (1. whom it map concern; f Be it known that I, CHARLES S. JAoKsoN, a citizen of the United States,residing at Fran klin, in the county of Warren and State of Ohio,
have invented certain new and useful Improvements in Paper-Bag Machines, of which the following is a specification.
The object of my invention is to provide a paper-bag machine which will automatically insert a strawboard plate in the bottom .of the bag during the process of manufacture; and my invention consists in the combination and arrangement of parts hereinafter described and claimed.
In the drawings, Figure I is an elevation of an apparatus for inserting a strawboard plate in the bottom of a bag, together with a diagrammatic representation of so much of a paper-bag machine as cooperates with the apparatus; Fig. 2, an elevation of the clutch mechanism for operating the apparatus; Fig. 3, a section on line 3 3 of Fig. 2 Fig. 4., a top plan View of the apparatus; Fig. 5, an end view of the apparatus; Fig. 6, an elevation showing the means by which the apparatus is driven; Fig. 7, a top plan view showing the bag as it appears in the process of manufacture just before the strawboard plate is applied; Fig.
8, a top plan view of the bag and strawboard plate after the plate has been applied and the first fold made, and Fig. 9 a top plan view showing the completed bag.
Reference-letter A denotes the strawboard plate; B, a rackfor containing the plates; 0, a feed-slide for delivering the plates; D, a rack-bar for operating slide 0; E, a gear meshing with rack-bar D; E, a shaft carrying gear D; F, a sprocket-Wheel for operating shaft E;
G, a chain operating sprocket-wheel F; H, a sprocket-Wheel operating chain G; I, a rod; J, a crank for operating sprocket-wheel H;
K, the bags; L, the nose of the paper-bag machine; M and N,tucker-blades forstarting the folds in the bag, and O and P foldingrollsof the bag-machine.
The plates A are placed in a pile in rack B, which is adjustable both lengthwise and crosswise for the accommodation of different-sized plates. An adjustable gate b is provided to permit the passage of the bottom plate and prevent the passage of the others. The sides I) of rack B are extended to form a channel for the plates A, and at its forward end the rack is provided with an adjustable table b having a folding extension b The slide 0 operates in guides c in thebottom of the rack and is provided with stops 0 and c for carrying the plates. The rack-bar D is carried by slide 0 and meshes with gear E, carried by shaft E. As a means for operating shaft E, I provide a sprocket-wheel F, loosely mounted on shaft E and carrying a clutch member 6, engaging a corresponding clutch member 6, fixed to shaft E. A spring e holds clutch members 6 and e in. engagement. between the engaging surfaces of clutch members e and e, so that there will be a little lost motion at each reversal of shaft E. In order. to obviate danger of-breakage by accident, the engaging surfaces of clutch members e and e are beveled, so that they will disengage should too great resistance be placed upon them. The sprocket-Wheel F is driven by sprocket-chain G, passing over sprocket H, which is operated through rod I by crank-arm J on shaft Shaftj is driven by some suitable power, so as to cooperate with the other operations of the bag-machine,
shafts of the bag-machine extended for this purpose. The length of crank-arm Jis such thatit does not cause a complete rotation of tion. Thus it will be seen that the crankarm J will impart a reciprocating movement to slide 0, having a momentary pause at each reversal due to the lost motion between clutch members e and e. In order to adjust the movement of slide 0, a turnbuckle i may be provided on rod I. At each forward movement of slide 0 stop 0 engages the bottom plate A, carrying it under gate 1) and past dogs I), which falling behind it prevent its return. On the backward movement of slide 0 stop 0 passes under plate A and engages it upon the next forward movement to carry it forward onto table 19 where owing to the pause of slide 0 at the reversal it is momentarily held against nose L of the bag-machine. While the plate is in this position the usual tucker-blade M descends and, striking the edge of plate A projecting over table b tips the plate, so-that stops m on the blade en- A space 6 isleft and may, if desired, be one of the regularsprocket-wheel H, but merely a rocking mo gage it and carry it down with the blade. In
order to accommodate dilferent sizes of plates, the stops m may be made adjustable. The extension b is pivoted to table b and has a rod connection with arm m on tuckerblade shaft m so that as the blade descends, the extension is automatically Withdrawn and replaced when the blade ascends. The usual operations of the bag-machine bring the bag K in the condition represented by Fig. 7, with paste applied along lines k is under nose L, and table 12 in proper position to be engaged by the descending tucker-blade M along line 70, so as to start a fold on this line. As the bag approaches this position its end has a tendency to curl up, and extension 5 prevents this. The tucker-blade M carries the fold in bag K and the inclosed plate A down into engagement with rolls 0,
which draw the bag through them, fold first. The rolls 0 apply the paste-supplied portions of the bottom of bag K to opposite sides of plate A,where they are held by the paste. After this operation the bag is in the condition represented by Fig. 8. As the bag continues itscou rse it is struck by tucker-blade N along line 10 k and carried through rolls P, completing the bag with the plate A in its bottom. The plate A is preferably of strawboard or other more or less porous material, which will absorb superfluous moisture and prevent the paste from becoming moldy or mildewed.
The tucker-blades M and N and rolls 0 and P are the usual parts of the well-known paper-bag machine for forming and pasting the folds in the bottom of the bag, and their operation for this purpose will be readily understood by those skilled in the art without further description. My invention consists in providing the means to cooperate with these parts, whereby the strawboard plates are automatically inserted in the bottom.
While I have shown and described the preferred form of application of my invention, this is obviously capable of many variations without departing from the spirit of the invention. I therefore do not wish to be limited to the exact form shown and described; but
What I claim as my invention is- 1. The combination, with the tucker-blade and folding-rolls of a bag-machine, of means for placing a plate in the path of the tuckerblade, to be engaged thereby and carried to the rolls in the fold caused by the blade, substantially as specified.
