20 Claims.

My invention relates to that class of machines which are employed for making cups for drinking and similar purposes from light, thin material, as for instance, paper, and an object of my invention, among others, is the production of a machine of this type that shall be rapid in the operation of making cups and that shall be particularly eflicient in producing the cups.

One form of a machine embodying my invention and in the construction and use of which the objects herein set out, as .vell as others, may be attained is illustrated in the accompanying drawings, in which-- I Figure 1 is a plan view of my improved cup making machine.

Figure 2 is a view substantially on a plane denoted by the dotted line 22 of Fig. 1 showing a portion of said machine.

Figure 6 is a similar view of a mandrel showing a cup body applied thereto.

Figure 7 is a view similar to Fig. 5 but illustrating the inturning of ,the bottom edge of the cup body to enclose a flange on the cup bottom.

Figure 8 is another similar view illustrating the position of a mandrel with the cup body and cup bottom thereon just before the final oper-- ation of securingthe bottom in place.

Figure 9 illustrates the manner of finally securing the cup bottom in place.

Figure 10, sheet 2, is a detail view in section on a plane denoted by the dottedline 1010 of Fig. 4.

In the accompanying drawings the numeral 10 denotes generally the supporting frame of my improved machine and 11 a table surmounting said frame and on which a turret 12 is rotatably mounted, said turret having mandrels 13 projecting radially from its edge to receive cup bodies thereon and bottoms in a recess in each end thereof, in a manner to be hereinafter described. A step-by-step rotating movement is imparted to the turret by a geneva mechanism comprising a driving member 14 having studs which enter slots in a driven member 15 of said movement in a manner common to mechanism of this type and which will be readily understood by those skilled in the art without further explanation herein.

The driving member 14 is rotated as by means of intermeshing gears 16 upon a turret actuating 00 shaft 17 having a gear 18 meshing with a gear 19 secured to a driving shaft 20 mounted in the supporting frame and driven from any suitable source, as for instance, a chain engaged with a sprocket wheel 21. 6

Each of the mandrels has a recess 22 in its outer end in which an ejector 23 is located and which is operated as by means of an ejector stem 24 projecting through the mandrel and into the turret and having at its inner end an ejecting 7 finger 25 operated by an ejector cam 26 along which the finger sweeps as the turret is rotated, said ejector operating to remove the cups from the mandrels after the bottoms have been sea further explanation concerning which is omitted herein as not necessary to a full understanding of my invention. Said plunger 28 forces a disk to comprise acup bottom into the recess, '22, a flange 30 having been formed as shown in Fig. 5 of the drawings.

In the next one-step rotation of the turret to a station designated herein as b a blank is wrapped about the mandrel by mechanism not necessary to be described herein, and the previously mucilaged meeting edges are stuck together to form a cup body 31 with the bottom end thereof projecting beyond the outer end of the mandrel, and as shown in Fig. 6. Up to this point the ejector 23 remains in the bottom of the recess 22, and as shown in Fig. 5.

When the turret comes to rest after the next one-step movement thereof to a station designated herein as c the finger 25 is engaged by a cam 69 on a cam slide 70 located in a groove in the table 11 and timely operated by mechanism 00 (not shown herein) to move the ejector outwardly and locate a cup bottom in position for assembly with the cup body. As the turret is again rotated the finger 25 passes from the cam 69 to the ejector cam 26 which is formed to retain the ejector in this position, as the finger sweeps along the cam, to the position shown in Fig.v 7, thereby retaining the edge of the flange 30 a short distance inwardly of the end of the cupbody. At this station 0 a clamp plate 3.2 having no on the disk, 85

' cup on the outer endof the mandrel is moved flange 30 on the cup of a spring 52.

.49 from any suitable radial movement in said into contact with the cup body to clamp the latter securely in place, said clamp plate'being mounted on a slide 33 movable between guides 34 secured to the upper surface of the table 11 and held in place by gibs, as shown in Fig. 1, said slide being timely operated in any suitable manner to clamp the cup bodies on the mandrels when the latter come to rest at this station 0. Said clamp plate is supportedupon rods slidable in the slide 33 and against springs 35 surrounding said rods and which springs force said plate into yielding engagement with the cup bodies, and as shown in Fig. 1 of the drawings.

Immediately following the engagement of the clamp plate with the bottom of a cup body the springs 35 yield to permit further movement of the slide 33 and thereby engage a. lip forming die 36, also supported on the slide 33, with the end of the cup body, projecting said end into a groove 37 in ,the die and thereby turning a lip 38 on the end of the cup body to enclose the bottom, and as shown in Fig. 7. In this operation of turning said lip the die may be rotated as by.means of a belt or belts passing around'pulleys 39 secured to a shaft 40 which supports said die.

After the lip 38 has been turned on the bottom edge of the cup body and the flange 30 has been enclosed within said lip the slide 33 is withdrawn by the mechanism which advanced it, thereby releasing the clamp plate and die from the cup body and mandrel, permitting the latter, in the next one-step movement of the turret, to be located at a station-designated as d herein. It is here remarked that the bottom edge of the cupblank has been daubed with mucilage in a-previous operation and as shown at whereby the cup bottom is tightly secured in place in a manner now to be described. Immediately following the location of the mandrel with the cup body thereon and the cup bottom in the recess in the end thereof having its flanged edge enclosed within the-lip 38, as just described, a clamp 42. carried bya slide comprising rigidly connected blocks 43 having flanges 44 held by gib-s 45 in sliding contact with a guide 46 is moved into engagement with the cup body, and as shown in Figs. 4 and 9 of the drawings. Said guide is mounted on and secured to the table 11 and a sleeve 47 is rotatably mounted, as in bushings, in the blocks 43 said sleeve having a sheave as secured thereto and driven as by means of belts source of power which may be, if desired, an electric motor employed'for the purpose of driving said sleeve, the some remarks applying as to the pulleys 39 for rotating the lip forming die 36. A spinner head 50 is secured to the sleeve 47 and supports slides 51 mounted for head, preferably'two of these slides being employed and each being pressed toward the center of the head as by means Each of said slides bears a spinner 53 supported .on an arbor proiectingfrom the slide, and as shown in Figs. 4, 3 and 9 of the drawings, said spinners being supported upon ball bearings, as shown in Fig. 4.

The slides 51 at their adjacent with recesses which combined ends are formed form a tapered cavity into which the tapered end of a'slide actu- 41 in Fig. 6,-

1,9eaosa I ing out of the rear end thereof and having a pin 57 engaged in a slot in the sleeve, and as shown in Fig. 4 of the drawings. A spring 58 is located on the plunger 56, one end of the spring resting against the end of the sleeve 4'1 and theopposite end of said spring resting against a grooved actuating head 59 secured to the plunger 56. An actuating lever 60 has a forked end with rollers engaged within the groove in the head 59, the opposite end of said lever being secured to an actuating shaft 61 mounted in brackets 62 secured to the under side of and projecting downwardly from the table 11. An arm 63 secured to the shaft 61 projects downwardly and has an actuating rod 64 secured thereto, the opposite end of said rod having a forked end straddling the driving shaft 20. A roller on said forked end of the rod 64 engages within a groove in a cam 65 secured to the shaft 20. v

In operation, the actuating lever 60 is rocked by operation of the cam 65 and the connections therewith just described. As the upper end of the lever 60 is moved forward it exerts pressure through the spring 58 upon the sleeve 47 moving said sleeve and all parts mounted thereon forward engaging the clamp 42 with the cup body upon the mandrel and to the position shown in Figs. 3, 4 and 9 of the drawings.

Springs 66 upon rods6'7extendingfromtheslide comprising the blocks 43 nowpermit movement of all of the parts just referred to with the exception of the clamp 42 and the slide engages with a stop 68, thereby preventing further forward movement of said members. Action of the lever 60 now forces the plunger 56 forward compressing the spring 58 and pushes the slide actuator 54 into the cavity formed by the recess in the ends of the slides 51 the spring 55 acting as a cushion for this movement. This separates the slides and moves the spinners 531 into contact with the lip 38 on the cup body thereby forcing the same tightly into contact with the flange on the cup bottom, securing the latter firmly in place. After this operation the lever 60 is retracted and the parts are moved to their normal positions and movement of the turret is permitted to bring a new mandrel with a cup body and bottom thereon into position for another operation just described. It will be noted that the stop 68 places the spinners 53 in proper position within the overturned edge of the cup body, further operation of the lever 50 body with its end projecting beyond the end of said mandrel, means within said recess for sup porting aflanged cup bottom within said projecting end, means for overturning the edge of said projecting end to enclose the flange of said bottom, and means for pressing said overturned I edge into ciose contact with said flange.
