WILLIAM CARTER, OF GLASGOW, SCOTLAND.

MACHINE FOR MAKING PAPER BAGS.

SPECIFICATION forming part of Letters Patent No. 626,319, dated June 6, 1899.

Application filed December 2'7, 1897. Serial-No. 663,578. (No model.)

To all whom it may concern.-

Beit known that 1, WILLIAM CARTER,a subject of the Queen of Great Britain, and a resident of the city of Glasgow, Scotland, have invented certain new and useful Improvements in Machines for Making Paper Bags, of which the following is a specification.

This invention relates to machines for making paper bags and such like; and it has for its object to improve and simplify the construction of such machinery.

Vith this invention the operations of pasting the sheets or blanks, folding them, and pressing them can all be performed on the one machine.

In order that my said invention may be properly understood, I have illustrated the same in the accompanying drawings, whereon- Figure 1 is a front view of the machine. Fig. 2 is a plan of the machine. Fig. 3 is an enlarged inverted plan view, and Fig. 4. a

similar side view, of the folding-knives and their actuating mechanism. Fig. 5 is a side view, Fig. 6 a front view, and Fig. 7 a back view, of the forming-block. Fig. 8 is a front view, and Fig. 9 a side view, of the paste vessel. Fig. 10 is a view of a paper bag made in the machine. The dotted lines y 11 indicate the bottom pieces y g) as turned over so as to form the bottom of the bag. Fig. 11 is a detail of the forming block and table. Fig. 12 shows the paper sheet as laid upon the baseplate of the machine. Fig. 13 shows the sheet with the bellows sides a CL partially formed. Fig. 14. shows the bellows sides completely formed by the turning over of the ends I) b, Fig. 13, of .the sheet on top of the formerblock 31. Fig. 15 shows the bag-blank, Fig. 14, with its triangular bottom parts 0 0 formed by the turning over in the usual way of the triangular flap 38 of the block 31. Fig. 16 shows the bag complete, with the triangular parts 0 c pasted down, which can be done by the machine described in the specification of my Patent No. 611,055.

Referring to the drawings, whereon the same reference-numerals wherever repeated indicate the same parts, the machine consists of a table or bed 1, which is supported upon standards 2 3 and provided underneath with treadle or other suitable driving mechanism. Situated at one side of the table is a paste vessel 4, which, as shown at Figs. 8 and 9, is of triangular section, with a narrow opening or slit 5 for the paste to pass through at the bottom onto the paper sheets. This paste vessel, which is capable of a vertical movement under the action of gravity or of a spring, is provided with guides 6 7, working in sockets 8 9 (see dotted lines, Fig. 8) in a plate 10, secured to the table. The guides 6 7guide the paste vessel in its movement. The sheets or blanks of paper to be pasted are simply laid evenly upon one another, with one edge below the opening 5 in the bottom of the paste vessel, which latter, owing to its weight or the action of the spring, bears upon them and pastes each one in turn. It will be easily seen that when the top sheet of the pile is removed the paste vessel sinks down onto the next sheet of the pile and pastes it, and so on until all the sheets are pasted. Adjustable gages 11 12 13 are provided on the table for keeping the sheets or blanks in place. As will be seen, the gages are slotted and clamped in place to the table by means of sockets fitted in the table and screws with butterfly-heads 14, which pass through the slots of the gages and into the sockets.

Arranged at one side of the pasting device aforesaid is the folding mechanism, which consists of two movable folding-knives 15 16, which are capable of being traversed forward and toward each other, so as to perform the folding operation for the sides of the bags by means of arms 17 17 18 18, having jaws 19 at their upper ends. pins 20, projecting from the sides of slippers 21, attached to the under sides of the knives. These arms 17 17 18 18 are pinned to two shafts 22 23, arranged parallel with each other below the base-plate 24:, which latter is secured to the table by means of screws at 25. Each shaft has an arm 26, and these arms are connected by means of a chain, wire, cord, or such like 27 with a treadle 28. The knives 15 16 are automatically retracted after each forward movement by means of torsionsprings 29 30, arranged on the shafts 22 23.

Arranged between the folding-knives 15 16 is a bag-shaping and bottom-forming block,

The jaws grasp pivotconsisting of upper and lower plates 3-1 32. (See Figs. 5,6, and 7.) These platesare connected rigidly together by means of a central rib 32 and rivets 33, and they are hinged at 34 to a pin 35, secured to the base-plate 24.

The upper plate 31 has a taperedend 36 with;

a hole 37 for the finger at or about the center thereof, While the lower plate 32 has a. correspondingly-shaped flap 38, but Without A recess 40 is cut out of the flap to enable the bag to be easily slipped off the block. The flap 38 isprovided with a projecting bar 41, which. The bar may be made.

the hole, hinged to it at 39.

serves as a handle. with a cutting edge, so as to cut the paper at that part when so desired. The spaces between the plates 31 32 of the block at each side are sufficiently wide to admit of the entraneeof'the folding-knives when the paper is being folded. The block is normally held in a vertical position (see Figs. 1 and 2) and up from the base-plate by means of a spring a2, which'acts on a hook 43 fitted to the block. In Fig. 2 "the dotted lines show the block in its down position. I

Adjustable gages 44 {t5 are provided as guides for inserting the sheets of .paper in the block-and folding mechanism.

25* are clamping-screws for the guides.

46 is a guide for the bar 41 at the end of the block.

Arranged at a con ven'iehtdistan'ce from the folding mechanism is the pressing device,

which merely "consists of a board or block' curved at its upper end and faced with brass.

This block 47 is fitted to the table of the machine at the back of the folding mechanism. After the bag has been passed through the folding device and'properly folded it is drawn by the attendant over the upper edge of the pressing-block 47, so as to smooth down and press the folds. From the pressing-block the bags are allowed to fall 'down through a hole 4.8 in the table onto a chute 49, which delivers them into a suitable receptacle.

The parts of the mechanism are so made and fitted together as to be easily taken asunder and cleaned.

The pasting device can also be adapted for pasting wrappers, sheets, and such like.

'When it is desired to paste two sides of a sheet, two pasting Vessels may be fitted on tn esame frame or bed.

The modus opercmdi is much the same as that usually adopted in this class ofmachines, viz: The paper sheet, after being pasted at one edge by means of the automatic paster, is laid on the base-plate'ZeL (the knives beingreuected) and the block is brought down upon it, Thereafter the knives areadvanced so as to force the paper at each side between the fplates of the block, and thereby form the bellows sides of the bag. This being dOneQthe free ends of thepaper (one of which is pastedas'aforesaid) are folded down 'on'top of the block and made to adhere together,and

then the knives "are retracted and the block brought to the vertical position by the spring, when the triangular bottom parts are shaped in the usual manner when making satchelbags. The bags are finally pressed on the block 47.
