' of the blanks, and to this end my invention comprises the novel details of improvement and combination of parts that will be more fully hereinafter set forth and then pointed out in the claims.

4Reference is to be had to the accompanying drawings forming part hereof, wherein- Figure 1 is a plan view of a machine embodying my invention, part being broken away, Fig. 2 is a longitudinal section thereof. Fig. 3 is a cross section illustrating, on opposite sides of the line a, different positions of the operating parts, Fig. 4 is a plan view of a blank for the paper dish. Fig. 5 is aside view of a folded dish, partly insection at the left of the line b, and Fig. 6 is an end view of the folded dish, partly in section at the left of the line c.

Similar numerals and letters of reference indicate corresponding parts in the several views.

The numeral 1 indicates a suitable frame, whose bed or table-like portion 1 is suitably dis folding members or die parts fit. At 3 is a vertically movable plate having side.

members 4, hinged to its edges, end members 5 hinged to its ends, and corner members 6 hinged at the corners or angles between the

adjacent members

4, 5, the

members

4, 5, 6 being adapted to rest upon the flat portion of the table when plate 3 is raised, as in Fig. 2

disposed forming a cavity 2 into which the up and down movements I have shown the same provided with depending plungers 8 that are guided in suitable bearings 9 in table 1, .said plungers having flanges 8a to limit their upward movement, springs 1U shown within said plungers and bearing against caps 11 secured on table 1, servin normall to raise plate 3, the arrangement eing suc 1 that when plate 3 yis raised to its uppermost position and limited by flanges 8a bearing against the table part the folding members 4,

5, 6 will extend outwardly substantially in line with plate 3. Above the

parts

3, 4, 5, 6, and reciprocative with respect thereto is a pressing plate 12, carried by rod or post 13,'

and to the edges of plate 12 are hinged folding members 14 that lie over the members 4, and to the ends of plate 12 are hinged folding members 15 that lie over the members 5.

To the members 14 and I15 are pivotally connected upwardly extending links 16, the upper ends of which are shown forked at 16a and carry pins 17 (preferably provided with anti-friction rolls) that enter vertical slots 18 in guides or wings 19 secured to post 13, which guides or wings are shown projecting from a sleeve 2() secured on said post. When post 13 is raised 'above plate 3, as in Fig. 2 and at the left in Fig. 3, the members 14 and 15 will be suspended in an outward position bylinks 16 and guides 19, but when said post is depressed to fold a blank for a dish the parts 17 will slide upwardly through the slots 18 for causing' pressure from Wings .19 through links 16 to the members 14 and 15 for pressing the dish blank, as at the right in ll`he blank to be folded in dish form is shown in Fig. 4 ,and has a centrally'dis osed portion A, side portions B, end portions C), and corner ortions D, all weakened by the score lines Eli shown in dotted lines, to permit proper folding of the blank. The end portions C of the blank have slots C and the edges of said portions C are cut on lines con'- verging outwardly, at C2, while the corner portions D are cut on lines D at an angle t0 the edges C2, to provide tongues F, and notches G are out in the outer or extreme edges of the corner portions D to engage the material at the outer ends of the slots C when the tongues F are pushed through said slots, in the. manner shown in Fig. 6, to lock the corner portions D to. the corresponding 'end' portions C. The blank is of such dimensions as to fit properly between the folding members previously described. ln order to open the slots C of the blank so that the tongues F may slide through said slots l. provide the members 5 with depressions or sockets 5a on their upper surfaces and the members 15 having corresponding projections 15a suitably alined with the sockets 5*?, sothat when a blank is in position between the folding members, as in Fig. 2, and the upper members pressed upon the lower members the projections 15a will press the parts of the blank' that lie between the corresponding slots C into the sockets 51L to o en the slots C and thus permit the tongues to slide into said slots. j

To cause proper operation of the parts above described I have shown post 13 connected with a cross bar or beam 20, and post 13 is shown movably connected to said cross bar by being adapted to slide in a bearing 20EL in said bar, said post having a head 13a and a collar 21 suitably secured to the post, a spring 22 fitting between the cross bar and collar 21, all whereby post 13 will be moved up and down with the crossbar but `the latter will act resiliently to prevent undue pressure and injury to the parts, but the tension of the spring will be sufficient to cause proper folding of the dish blank by the'folding members. Said cross bar or beam 2O is rigidly connected with depending arms 23 whic-h travel in upright guides 24 secured upon frame 1, and inks 25 are ivotally connected with said arms and with) cranks 26 at the ends of a shaft 27 suitably journaled in frame 1, whereby cross bar or beam 20 is reciprocated. At 28.\is a shaft journaled in frame 1 and shown provided with a drive pulley 29 and alsoprovided at opposite ends with gears 30 that mesh with gears 3]. on shaft 27 for rotating the latter.

l. have also shown means for cutting the blanks for the dish from a continuous strip of paper or other suitable material A2, cutting the outlines of the various portionsA of the blank, and scoring the same, and for also feeding the out and scored blanks to the folding v`devices intermittently. For this purpose I provide a roll 32 that is journaled in suitable bearings upon frame 1, andis pro? vided upon its periphery with proj eeting cutters, arranged so that inone revolution of ,the roll the blank will be cut to the required width from strip A2 by the cutter 33, while the cutter parts 34 cut the outer edges of the corner portions D of the blank, the cutter parts 35 cut the notches G, the cutter parts 36 cut the outer portions of the tongues F,

the cutter parts 37 cut out the angular piece between the edges C2 and D', and other cutters score the lines E in the blank, while suitable cuttersform the slots C and cut other necessary ortions of the blankthe cutters being sim' ar .at opposite ends of the roll, and

also similar on opposite sides of` the longitudinal blank separating cutter 33 so that as roll 32 revolves once a complete blank will be cut, scored, and severed from strip A2. A corresponding roll 32a is journaled in frame l beneath roll 32 and has suitable cavities in its surface that correspond with the cutters of roll 32 to permit the operation ofthe eutters thereon; said rolls also serve to feed the paper strip and blank. The rolls 32 and 32L are connected by

gears

38, 39 to rotate in unison. At 40 is a roll journaled in suitable bearings on frame 1, between roll 32 and the folding members, and rotated in unison with roll 32 b a gear 41 meshing with gear 38. Roll 40 as suitable projections 40a, similarly arranged and disposed near opposite ends thereof, ada ted to engage the cut out pieces of the dishll through suitable openings 1b in frame 1 (see Fig. 2), so that such pieces will not be carried along with the blank to the folding members. The rolls 32, 32a and 4() may be intermittentl rotated to yaccord with the operations o' the folding members in any suitable manner. For this urpose I have shown shaft 28 provided with) a broken gear 42 having a suitable number of teeth for part of its circumference and the remainder of the circumference provided with no teeth,

said teeth being adapted to engage a pinion 43 secured upon a shaft 44, suitably journaled in frame 1, and carrying a gear 45 that meshes with a gear 46 secured on shaft32D vof roll 32 a. By this means, as shaft 28 rotates it may cause continuous reciprocation of,

ing members rise a folded dish H may be removed by hand or by any suitable means, and then. a cut blank will be pushed over the lower set of folding members by means of the next following blank, in 'position shown in Fig. 2, and when the upper set of folding `members descend they will bear upon .the

blank and thereby push the blank and the lower set of foldin members into cavity 2 carrying the

centra plates

3 and 12 straight down and holding the central part A of thev blank firmly, while at the same time the hinged folding members will fold upwardly in the manner shown at the right in Fig. 3, thereby bending the blank on the score lines E, and the projections 15a will push the parts of the blank that lie between the slots C into the recesses 5'l and, as the corner folding members 6 fold upwardly, the corner ortions D of the blank will be caused to ,s ide inwardly behind the end portions C thereby carrying the tongues F into the slots C', and

lank and push such pieces `With a cavity, a movable .ceases by one compressing action of the folding members the side, end, and corner portions of theblank will be folded in dish form, as shown in Figs. 5 and G, with the tongues F projected through the corrcsionding slots C and locked hy the notches (it.

folded dish li may be removed While another blank is next presented between the sets of folding members, so that at each complete down and up stroke of post 13 a dish may be folded and its tongues locked in the corresponding slots, the lower set of foldinglnembers rising under the influence of springs 10 at each. elevation of post 13.
