To all whom it may concern:

Be it known that I, GEORGE W. BEADLE, a

citizen of the United States,.residin at Bayonne, in the county of Hudson and tate of New Jersey, have invented certain new and useful Improvements in Machines for Making Carton-Bodies; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use the same.

This invention relates to machines for forming carton bodies, and has for its object to produce a mechanism which will readily reduce the diameter of spirally. wound tubes at predetermined positions in their length, and thereupon sever such tubes at the reduced portions to form carton bodies having reduced ends over which cap closures may be slipped.

The invention consists in the novel details of construction and combinations. of parts more fully hereinafter described and particularly pointed out in the claims.

Referring to the accompanying drawings forming a part of this specification inwhich like numerals designate like arts in all the views :F igure 1 is a side e evational view of a machine made in accordance with my invention, with certain parts omitted for the sake of clearness; Fig. 2 is an end elevational view of the machine including the.

parts omitted from Fig. 1;Fig. 3- is a cross sectional view of a portion of the parts shown in Fig. 1; Fig. 4 is an elevational view of a portion of the mandrel and showing'the tube thereon in sectional view; Fig. 5 is. a perspective view of a carton body made by this machine. p

1 indicates any suitable supports orlegs for the machine proper; 2 the bed of the machine; 3 a standard or bracket rising from the bed 2; 4 a second standard also rising from said bed; 5 an additional standard; and 6 still another standard pivoted as at 7 to a bracket8, and provided with a bell-crank extension 9. w

Passing through the standard 3 is-one end of a the mandrel 10 on which is also secured a pulley 11, and said mandrel "is provided at its other end with a reduced portion 12 fitting a hole 13 in the hinged standard 6, as shown.

I The said hinged standard is connected as at 14 with the one end of the rod 15. whose other end is at 16 connected with one arm 17'of the bell cranklever pivoted as at 18 to. thebed- 2, and having another arm 19 to which is pivoted as at 20', a/ rod 21, to which is attached as: at 22 a foot lever 23,. pivoted to the rod 24 secured to the. supports 1.

A' spring 25 normally keeps the. foot. lever 23.- in its ralsed position, and when the said lever. is depressed, the pivoted standard 6 forced from its full line position shown in Fig. 1, mtoits dotted line position in engagement with the end 12 of the mandrel,

as will be readily understood.

A shaft rod 30 is journaled in the standards 4 and 5, and has secured thereto the pressure shoes 31 having the curved circular shaped surfaces 32 adapted to contact with forced by the curved surfaces 32 to. form the depressicns34, as clearly illustrated in jets are connected by; the tubes. 38 to the gas pp g pipe 39'. The several shoes 31 are move nto andout. Of engagement with the tube on the mandrel by the handle lever 40 Fig. 4. Said. depressions formed in thetube I that is pivoted to the stud 41 on: the standard 5 (see Figs. 1 and 3).,and is provided with a slotted arm. 42' which. engages the pin 43 carried by the arm 44, that is rigid with the shaft 30, as best shown in, Fig. 3.

It" is. evident that when. the lever 40 is depressed, its, rigid'extension 42 will be swung ina clockwise direction, (see Fig. 3)

and carries with it the pin 43 and: the lever 44, which latter being rigid with the. shoe 31-, will swing said shoe in a cou1iter-clockwise-direction, or against the carton 33, and force the material of the same into the grooves 36 on the mandrel 10.

the pulley 11,. and the shoes 31 being, heated The mandrel 10' being revolved through finished tube presents the appearance best illustrated in- Fig. 4. The whole operation is quite rapidand efiicient.-

While the tube is being grooved by the heated shoes, the knives or disks 50' are.

brought into contact with the depressed portions 34,and sever the same along the lines 51,as best indicated in Fig. 4. Each of these knives is preferably in the form of a disk, as shown, and is carried in a bracket 52, (see Fig. 2) and adjustable bymeans of the screw 53. A cutter support or bracket similar to that shown in Fig. 2 is provided at or near the free end of the mandrel;

The several brackets 52 are adjustable to and from the carton 33 by' means'of the screws 54"pa'ssing through the bearingsv 55 d" with the brackets'56 mounted on the 2 ef themachine. The said screws 54 constitute thesupports for thepivots 56 of the bars 57 ,on which; bar said-brackets and knives are mounted, and said bar is provided with an arm or extension .57, having pivoted, seat 58, the rod 59 that is .connectedat 60 with the foot lever 23;

vItwill now be clear that'as the foot lever 23 is depressed, it will pull down on the rod 59, and will cause the bar 57'to swing on the pivots 56, and to thereuponforce the knives 50 into contact with thecarton 33.

In the'meantime,it will also'be clear that the pivots 56 can be bodily. shifted to and from the carton tube'33 by moving the nuts 61 surrounding saidscrews 54:. 'It will furtlier be clear that uponadjusting the screw summarized as follows :'-A tube of uniform diameter and preferably of a spirally wound character, is slipped over the mandrel 10,

provided with the grooves 36, which. man- 50 drel is of a diameter somewhat, less than that of the tube, as shown. The pivoted bracket 6 is next swung into its dotted line position,-as shown-in Fig. 1, by a depression of the foot lever 23. Power being continuously applied to'thepulley 11, the said mandrel is rapidlyrotated, and upon a' depression of the handlever 40, the compressing shoes 31- are brought into contact with the tube 33 .and force the material-of the same into the tapered grooves 36,- as illustrated.

The gas jets 37 maintain the shoes 31 at a" sufliclently high temperature-to rapidly and permanently set the material of thetube,

and therefore-to form; it. into the shape shown in 4. On the same depression of "on; and a shoe ada .of the tubular b0 y -"into said mandrel the-'foot-lever 23, the knives 50 are brought into contact with the said tube at the depressed portions 34, and sever the said tube along the dotted lines 51 into. suitable lengthsfor making carton bodies 70, as illustrated in Fig. 5. The said tube 33 beingof a greater diameter than the mandrel 10, these carton bodies '(0 are readily slippedofi the said mandrel, and are supplied with suitable closures, not shown. The removal of the saidbodiesfrom the mandrel is facilitated: by the faet'that thespring 25 'automatically raises the foot lever 23as-soon as pressure; is. removed therefrom, and thereupon,-forces' the pivoted supporting bracket 6 .intoIits full line position shown in Fig. 1, a

and leaves the end-of-the mandrel 10 clear.

Itis obvious that those skilledin the art j may vary the details of construction as well as the arrangement of parts without departing from the spirit of my invention, and thereforefl do not wish to be limited to the above'disclosures except as may be required by the claims- II elaim v p I.
