Application filed June 21,1906. Serial No. 322,747.

To all whom, it may concern:

Be it known that I, EDWARD EMIL CLAUS: SEN, a citizen of the United States of Amerand a resident'of Hartford, in the county of Hartfordand State of Connecticut, with a ,post-office address in'the above lace, have invented certain new and usefu Improvements-. in Paper-Bag'Machines, of which the following is a specification.

to' This invent on relates to machinery for automatically manufacturing square-bottom paper bags from tucked paper tubing.

The object of this invention is to provide a machine that formsthe diamond of a square- I 5 bottom paper ba on a bellows-sided tubing,

the mechanism fhr pasting and folding the end flaps being omitted, as the same are well' known in the art.

"In my Patent No. 813,280, of February 20, 1906, I have shown a machine embodying this general type in which a blank-support moves back and forth upon the surface of a cylinder, and'inthe machine forming the subject-matter of the resent invention I 2 5 have embodied some 0 the features of the invention disclosed in'1 my patent above mentioned. The fcompres'sionsplates 110 are, however, tube a little lon er, so that'they .pressthe bag-blank to t e cylinder and erease the same at the primary transverse folding-line. i In order that those skilled in the art to which my invention relates may fully understand the'n'ature and construction of the 3 5 same and may obtain'a better knowledge of the several 0' erations required, Iwill first give a detaile description of each individual mechanism, reference being had to the accompanyingdrawings, which form a part of this specification, and in which.

I Figure 1 represents the right-hand side elevation of the frame and cooperating folding mechanism in its preferred construction. Fig. 2 is a front sectional elevation taken on the broken line 2 2 of Fig. 1. Fig. 3 is a sectional plan view on the broken line 3 3 and in the direction of the arrows of Fig. 1. Fig. 4 is a plan view of the top of the blank-support as represented in Fig. 1, the blank-support 30 being shown .in the rearward ,position, or in the position where the tucked paper tube is delivered onto the same. Fig. 5 1s a similar 1 plan view as Fig. 4, out having the blanklsupport thrown for-ward, or in a position where the diamond form is completed. Fig. 6 is a front sectional view on line 6 6 and in l the direction of the arrows of Fig. 1, the I left-hand side bein" shown in section, whereas the right-hand side shows an outside view, the folding ins trumentalities bein r repriesented in the lateral outer position of adjustment. Fig. 7 is a similar view as shown in Fig. 6, having the folding instrumentalities shown in the laterally inner position of adjustment. Fig. 8 represents a side view of l the frame; Fig. 9 is asectional front elevation on line 9 9 and in the direction of the arrows of Fig. 8. Fig. 10 is a right-hand side elevation of the machine, drawn in a-reduced scale.

The directions of the movements of parts are shown by adjacent arrows, and the positions of the different folding instrumentalithe positions to the cams which move tliese instrumentalities, it being sufficient for the purpose of this descri tion to say that the cams are properly lai out and cut to produce the operations of the folding instrumentalities at the proper time andto the required extent.

Referring to my Patent No. 813,280, February 20, 1906, on a paper-bag machine, the tucked paper tubeis taken from the former and guided into the bite of the drawing-

rolls

38 and 39 and drawn into the machine, severed into bag-blank lengths, and conveyed by the conveyor-roll 44 and the conveyersector 45 to the blanlcsupport, which is all identical in construction except the blanksupport.

Referring to the accompanying drawings, the frame (designated in a general we the numeral 10) is mounted on the shaft 11, which is mounted for rotation in the direction of the arrow 14 in the

stationary bushings

12 and 13. The frame is of peculiar construction and best shownin the detailed drawings, Figs. 8 and 9, and is arranged to carry six folding mechanism all indentical in construction. The frame 10 consists of the central hub 15, which is pinned to the shaft 11 biy the taper pin'16, and from which extend t e eentral radial ribs and webs 17, termi- BAG MACHINE COMPANY, PHILADELPHIA, PENN SYL- ties are shown irrespective 'of the relations of i nating in the cylindrical sectors 18, which form part of the folding bed'. Laterally situated on each side of the central radial ribs and webs are the

hubs

19 and 20, from which 5 the

arms

21 and 22, respectively, branch forth and terminate in the

hubs

23 and 24. The

arms

21 and 22 are joined to the central ribs and web 17 by the cross-ties 25. The

hubs

19 and 20 are j ournaled on the

stationary bushings

12 and 13, respectively, and by this construction the frame is strong and firmly supported and well adapted to carry the various folding i1istrumentalities.

The folding instrumentalities are as folr 5 lows: The frame is provided between the ribs 17 with pivots 26, upon which are mounted the arms 27, carrying on their outer bifurcated ends the sleeves 28, upon which the blank-supports 29 are pivoted. These blank- 20 supports have their outer or working'surfaces curved to correspondwith the sectors 18 of the frame 10,' and the pivots 26 are so disposed that the top surfaces of the blanksupports. form a complete circle when inla :5 forward or rearward position, as shown in Fig. 1.

The mechanism which hold the lower half of the tucked paper tube to the blank-support are as follows: Passing through the 0 sleeve 28 on one side is the front-clip shaft 30, to which is fastened on the inner side the front clip 31 and on the outer side the arm 32, to which is jointed the connecting-rod 33, Which is in engagement at its lower end with 3 5 the lever 34, pivoted on the stud 35, which is rigidly supported in the arm 27 and has on its opposite side the cam-roll 36, which engagest e statlonary front-clip cam 37 on the sta tionary bushing 12. By the mechanism just 0 described the front clip 31 is caused to be opened and closed at predctcrinincd intervals onto the top surface of the blank-support the frame is rotated, the spring 80 tending to keep the cam-roll always spring-pressed in 5 engagement with the cam. Passing through the sleeve 28 on the right-hand ,side is the side-clip shaft 38, which has attached on the inner side the branched. lever 39 and on the outer side the arm 46, which is connected to the connecting-rod 41, \vhichis engaged at its lower end to the cam-arm 42, provided with a cam-roll which engages the stationary sideclip cam 43, held sccurclyon the stationary bushing 13. The spring 31 has one end attached to the lever 42 and the other end hooked to a pin of the stud 26, and thereby keeps the cam-roll spring-pressed to the cam. The bevel-edged side clips 14 are pivoted to each side of the blank-summrt on pivots 45, and they are provided with inwardly-projecting arms 46, upon which the spring 47 acts, so asto close the side clips upon the blank support, and are opened by the branched lever 39, ei'igaging from the under side of the arms 46.

The mechanism for reciprocating and oscill lating the blank-supports back and forth in the direction of the rotation of the'frame and toward and away from the center of the frame, respectively, will now be described.

the arms 51, which engage the trunn ions 52, forming a part and extending to each-side of the blank support, and the line passing through the centers of the trunn ions coincides with the top surface of the blank-support.

to the shells 50 are the sector-pinions 53, meshing into the sectors 54', pivoted on studs 55, held in the arms 21 of the frame,'and these sectors are provided with the cam-rolls 56, engaging stationary cams 57, held on the

stationary bushings

12 and 13. The springs 58 have one end attached to pins driven into the sectors 54, and the other ends are fastened to hooks in the

hubs

19 and 20 of the frame, and as the same is rotated the camrolls 56 follow the cams and through the intermediate mechanism cause the blank-support to move forward. and also to oscillate'toward and away from the center of the frame from the position shown in Fig. 1 at the top of the drawing to the position shown at the righthand side thereof, the front end of the blanksupport having been guided by-the arm 27, previously .describe .l. It will be observed the tucker-plate (described in the following naragraph) follows the movements of the blank-support mathematically correct.

The mechanism that clip and o crate above. the paper-bag blank will now e described.

, Held by a spline and feather 59 in the shell 50 is the hollow shaft 60, into which is screwed the head 61, which is flattened out on defining edge which corresponds with t axial alinement of the trunnions 52 of the curved blank-support. In the head 61 is a small shaft 63, upon whigh is pivoted the bevel-edged. ni'pper 64, provided wit-h an extension 65, a ainst which presses the springplug 66, held in a recess of the head 61, and is also provided with a nose 67, engaged by the rod 68, the outer end of which is connected to the lever 69, pivoted in the flanged member 7 0, securely screwed into the outer end of the hollow shaft 60. The spring 71 surrounds the rod 69 and is inclosed in the hollow shaft 66, presses upon a collar of the rod 63, and thereby kce )S the nippers 64 in an opcn position while the head 61 is in the out ward" position, as shown in Fig. 6. When,

strikes against the sector-pinion 53, and as that mward motion is. ontmued the move l munt of rod 68 is arrested and disengages that in this construction the defining edge of one side, forming a tucker-plate 62, havingla however, the head. is nioved into the inward position, as shown in Fig. 7, the set-screw 72 In the hubs 23 of the frame 10 are jourinale'd the shells 50, having on their inner ends On the outer sides of the hubs 23 and fastened the nose 67, andthe sprin 66 begins .to press upon the extension 65, t iereby closing the nipper 64 onto the tucker-plate 62.

The mechanism for moving the head 61 laterally in and outward are as follows: The bifurcated lever 73 is provided with pins 74, engaging between the collars of the flanged men1ber70, ispivoted on the pin 75 in the forked head 76 of the stud 55, and carries at its lower end the cam-roll engaging a groove in the stationary cani 78,-held on the hub of the cam 57, which is supported on the stationary bushings.

The operation of the machine is as follows:

The tucked paper tubing having been properly formed and severed into bag-blank lengths of proper widths and len ths is delivered onto the blank-support 29, the frame having been set in motion in the same manner as described. in my. Patent No. 813,280, of February 20, 1906, previously mentioned, and the lower ply of the tube is clipped by the front clip 31, and the lower tuck is held by the bevel-edged side 'clips 44, which are actuated by the cams 37 and43, respectivley, at regular predetermined intervals. The bifurcated levers 73 are then caused to be oscillated by the cams 78, moving the oppositely-disposed heads 61 laterally toward each other, thereby bringing the set-screws 72 up and against the sector-pinions 53, and as the inward motion continues causes the rod 68 to disengage the noses 67 and permit the springs 66 to close the bevel-edged nip ers to grip the upper tuck of the tube 3.1K hold the same to the tucker-plates 61. The sectors 54 thcnbegin to oscillate through the action of the cams 57 and oscillate the tuckcr nlate downward, forward, and upward from the position as shown in Fig. 1 on the upper left-hand side of the drawing to the position as shown in the lower right-hand side and convert and unfold the tucked paper blank and refold the same into the diamoi'idform, the defining edges of the tion of a continuous rotating frame, the arm tucker-plat-es following the exact movement of the blank-support at the point of contact, which: is the creased primary transverse foldingdine in the bag-blank.
