CARTON-MAKING MACHINE.

Application led February 27, `1924. Serial No. 695,431.

To all fr0/wm t may concern.'

Be it known that I, HENRY F. SHAFFNER, a citizen of the United States, and resident of VVinston-Salem, in the .county of Forsyth and State of North Carolina., have invented certain new and useful Improve ments in Carton-Making Machines, of which the following is a specification.

My invention relates generally to an attachment for a machine of the type shown in the patent to Ludington, 561,332, for making paper cups or cartons for cigarettes, snuff, or the like, and is illustrated in connection with a machine of this character although not limited thereto.

1n the machine shown in the patent to' Ludington, a magazine isprovided vwith a pluralty of blanks and a series of formers or mandrels are rota-ted step by step through four different positions in each of which they remain stationary for Aan interval. In the first position a blank is taken from the magazine, gummed appropriately and placed on the former where it is held by a clip. The paper is also folded and the side glued. The former then moves one-quarter of a revolution to the second position where the first folds of the end are made. other Vstep brings the former to the third position where the end is completed and the carton is then fully formed. The final step to the fourth position brings the formerto a point where the Vfinished cup or carton is stripped off the former. The operation is then repeated. Of course when the machine is running, all four formers are in use and all stages are attained in sequence by each former. u

It has been found that this method of manufacture produced a cup or carton the bottom of which lacked sufficient stiffness for proper durability in the filling and use of the same.

My invention relates to an attachment by which a piece of cardboard will be placed in the bottom -of each cup formed as indi cated above and glued therein, thus impart# ing sufficient firmness and strength to the completed cup.

An object of the invention is to Vprovide an attachment of this character which will be applicable to the machiner with very few changes and which will not interfere in 4any way with the operation of the other instrumentalities. i

.,Another object .is to` provide means for taking a card from the bottom ofthe magazine and placingfit on the end of the former, where it is held throughout the lmanufacture of the cupV or carton.

Other objects will be apparent from the following detailed description and the appendedA claims.

Figure 1 shows a view of the entire machine whichhas a frame A and a bracket or shelf B for tlhe support of the` operative parts. Power is transmitted to the shaft C from any suitable source and drives the is a section on tlhe line 7,-1-7 of 4' machine. A member D is given a step-by- Cil step rotary movement, and.: carries fourv ormers or mandrelsE. This member Dy stops momentarily at four points in its revolution sol asto bring each 'former successively into tour dil'erent positions, two ot which are designatedin Figure 1 at ll and III. lVhen in the first positionhivhich, is diametrically opposite to position 1LT., a

sheet of paper is takentronithe magazine .p

sition 11, the finished cupV isstrippedtroin the former, thus completing the sequence orc operations. The operation thus.. fa-rv, describefd is or may besubstantiallythe same as that of the. Ludington patent, and the structure ot' the machine is similar to that there disclosed.

Myinvention relates to an attachment tor placing a pasteboard bottom in thefcup or carton termed by the machine briefly de-n scribed above., lt involves only-'slight-modiication otl the trame, ot' the machine andk practically no modification `of the mode of operation.

A shaft l driven in any, suitable manner carries a sprocket wheel 2 about which passes Aa sprocket chain ,3 which passes about a sprocket wheel 4 on a shaft 5 supported in bearings in a bracket G on the frameot the machine. An arm 7 on said shaft has a cam 8 pinned thereto by a ries a roller lO which works in a groove 1l in a cross head 12.

A bi'acketinember'13 (see Figure 13) has a lat portion overlying the shelf B to which it is t'astened by boltsyor screwspassing` throughiholes 15. lt also. has a doWnu-'ardly extending ledge portion'l provided with bores 17 and ,18, as well as an arm 1S) Awhich has an offset 2O at its lowr end provided with

bores

21, 22 andv23. A stop screw 24 is threaded through the member 13 Iand held in adjusted position by a loclr nut 25.

Associated with the cross head 12 .and the bracket 13 are three rods `26 27 and 2S. The rod 26 passes through

thebores

17 and 21 and through a bore in the cross head.l

lt is revoluble in said bores but is prevented from endwise movement relative to the vcross head by` means ot collars 29 and.` 3.() fitting; above and below the cross head and fastened to the rod. V'llhe rod 26 is normally held in one position by a spring 3l fastened at one end to a pin A32 on the collar 29 and at its other end to a pin 33 on the cross head.

As hereinafter.pointed out, Figure 5 represents an intermediate position vot' the parts.. The.

rods

26 and 27 act to operate mechanisintor stripping the finished carton or cup .'l'rom the tormer, and in themselves arenotnew.

The rod 28 slides through openingsltV and 23 anda bore vin the cross head, but does not .receive its movement trom the cross head which nierelyacts as a guide for said rod. livotally mounted `in a'braclret 42 carried by the trame is .an angulanarmp43 having?. pivoted at 44 to its end anupward extendingarm 45 whose upper. end is pivoted on a pin 46 ina cut out 47 ofV a collan 48 that is fastV on the rod 28..., larried by the arm 431is .a roller 49 with which con.-

tacts .the edge .ot the cam 8. i A ,collar 50` is carriedby the upper portion ot' the rod 28 and. limits its movement. A link 5l pivoted to the arm 43 has a spring 52 connected thereto and the other .end of the spring is tast to a hook 53 carriedby the.

trame.

Each former has a central Vcylindrical bore ,in which slides a plunger 54 whicn open at its upper endy and a spring ccntained within the plunger is fastened at one end thereto and at its other end to a pin 5,6. Through one side oii theforiner a slot 5T communicates with the cylindrical boie and the plunger has an angular finger 5S attached thereto and extending' through tliebore. `When theparts areiniiormal position, shown for enamplein dotted linesy A at 82 to an arm 83 carried by the shaft 74.A

ment of the former. As the cross head 12 and

rods

26 and 27 move downward from position X (Figure 2) to position Y the plunger 54 is pulled'down also and strips the completed cup olf the former. At position Y, the bloolr 40 engages member 20 and cannot move any farther. The rodV 26 continues to move and the finger 35 is calnmed to one side by the cam groove 41, turning the rod 26 so that the lip 37 slips off of the finger 58 permitting the spring 55 to return the plunger' to normal position within the former.

The rod 28 has a pin 59 at its upper end, and this pin engages and operates mecha nism for feeding a lcard from the magazine to its position on the former. This will now be described. Y

Fitting in cut out 60 of the shelf B is a member 61 that is fastened to said shelf by bolts passing through holes 62 in the member and cooperating holes 63 in the a bearing fora certain operating sha-ft. It'

also has a groove 68 within which is placed the card feeding slide mechanism. l

The card magazine consists of a member fixed to the arm 65 and having one open side, together with a removable container 69 of similar shape fitting therein and con-` taining the cards. A weight Q70 is placed upon the cards, and the container has an ear 71 through which passes a screw 72 which 'may engage or be threaded into the magah zine. proper 66. The cards Z are of any desired size and thickness and are shownin Figure 15..'

An upwardly extending bracket 73 supports one end of a shaft 74, the other end of which has bearing in an enlarged portion 7 5 of the side of the magazine 66." A shaft 76 mounted in the ears 67 has an arm 77 provided at its end with an openslot- 78 in which engages the pin 59 carried by the rod 28. Another arm 79 is carried 'by' the shaft 76 and has a slot 80 therein in which works a pinat onel end of an adjustable link 81 the other end of which is pivoted T he free end of the arm 83.is provided with a slot 84 which cooperates with a pin 85 in the card slide.

Two side pieces 86 fit within the channel 68 in the member 61 and attached to their ends are members 87 which are'also fastened to rectangular rods 88 that are spaced from the members 86 to form guide slots 89. The card slide 90 has side extensions 91 which fit within the slots 89 so that the slide isguided in a right line. Ina depression in the inner end of the card slide is mounted a movat one side of the card.

- Springs '97 surround these rods between the nuts and the slide, and the tension of the springs can be adjusted b moving the nuts.v These springs tend to holt the member 92 in its'depression in the slide 90'as shown in Figure 9. A downward projection 98 at the inner end of the slide acts as a stop for the return movement thereof. When the parts are in normal position as shown in Figures 1 and 3, the member 92 of the slide underlies the card magazine with the projections 93 slide brought about by a downward movement of the rod 28 acting through partsk 59 A movement of the and 76 to 85 inclusive, causes the projections93 to catch the lowermost card in the magazine land move it through the cut out side of the magazine toward the former. /Vhen it is in a position close to the former, the cup stripping plunger 54 is released by the lip 37 and returns to normal rposition out of'the path of the card moving slide which is then moved underneath the former vby the further downward movement of the rod 28.

Referring particularly to Figure 6, it will be noted that the `member 92 Vcarrying the cardis lifted in the following manner.v The card slide has pivoted thereto at 99 a lever 100'having a lower cam surface at 101 and oarriesa finger 102 which underlies the rod 94 and lwill raise they rod and member 92 when it is moved upwardly. An arm 103 is pivoted to the slide to swing freely, and this arm carries a roller 104 intermediate its ends and another roller 105 at its end. The roller 104 supports the lever 100 and cooperates with `the cam surface 101. The roller 105 cooperates with a cam member 106 having an angular portion 107 fastened by a screw bolt 108 to the member 61. As the card slide moves inward the roller 105 will 'spring' As soon as the roller .105

movesoi" thecaininember=106 which takes place rjust-- an instant afterthe parts reach the Figure 6 position the arm 103 Willv swing.,
