BASKET-MAKING MACHINE.

Specification of Letters Patent.

Patented Apr. 22, 1919.

chines of the class used to manufacture bas-l kets, boxes, cartons, crates, barrels and other receptacles made of very thin sheets or slices or .veneers of wood, or other suitable materials or substances, and bound or reinforced by a. metallic strip or strips, or other suitable material or materials, or substance or substances.

An important object of my invention is the provision of a machine, simple in construction, that will greatly reduce the amount of Waste material, caused by deformation of the baskets, boxes, cartons, crates, barrels` or other receptacles, so frequently occurring in machines as at present constructed.

Another important object is to provide a machine that will manufacture baskets, boxes, crates, cartons, barrels and other receptacles, of any size or shape, made of very thin sheets, or slices, or veneers of wood, or other suitable materials or substances, and bound or reinforced by a strip or strips of metal, or other suitable substances.

Another important object is toy provide a machine that will attain a maximum productive efficiency per hour and be economical in power consumption.

Other objects will become manifest@ It is desired to provide a machine that will form or manufacture a basket, box, crate, carton, barrel or other receptacle of two pieces, or sheets, or slices, or veneers, of wood, or other suitable material or substance (which will be referred to hereinafter as slices), that have been previously shaped and sized in blank, by automatically placing one across the other, bending` the projectingportions to form the sides and then binding the edges to form the permanent basket, box, crate, carton, barrel or other receptacle, and ejecting the same from the machine. Any thickness of bottom and sides may be attained by using, as the case may be, more than one set of slices.

My invention comprises details of construction, the elements and the combination of elements, and will be clearly explained by reference to the drawings, in which Figure l is an end elevation and section through the mold. Fig. 2 is a perspective view of the buffer. F ig. 3 is a perspective view of the binding-strip bending frame. Fig. 4 is an enlarged view of the bindingstrip cutter knife. Fig. 6 is a front elevation. Both Figs. 5 and 6 show the grouping and the connection of the tin cutting and V or U shaping machines and the binding-strip cutter knife and the binding-strip bending frame, as well as the automatic slice delivering device, with the modified basket or other receptacle making machine proper.

The embodiment .of my invention as shown in Figs. l, 5 and 6 comprises a crossarm carrier 1 carrying four or more formers 2, one on each arm. These formers 2 are held in position by screws 3, through corresponding slots in the arms. Each former 2 has a centrally located extension for the purpose of holding and guiding the sliding shank 62 of presser-foot 63 as shown in Fig. 1. This former extension fits in a slot in the arm of the cross-arm carrier l. Slidingshanks 62 are provided with pressing springs 75 which press against the sides of the former extension, thus holding the sliding Shanks 62 by means of friction. On the upper ends of the sliding Shanks 62 are attached the adjusting sleeves 76 by the screws 59. Each former 2 is provided with the pins 23l of suitable size projecting out and downward around the rims. By this means the slices of whatever material or substance are picked up andl held. When forming the baskets or other receptacles, the cross-arm carrier l lowers the formers 2 over the buffer 25 and the mold-block 24. The presser-foot 63 is held back in this downward movement by the buffer 25, causing the slices to be held between their two plates, while the sliding shank 62 of the presser-foot 63 is protruding in its entire length above the former exteni sion. The pressing springs 75 are holding it in thisA position in the former extension, while the former 2 with the finished basket or other receptacle in it is raised back into its original position and is then carried around one quarter section. y

The basket ejector-plate 26 is fastened by the set-screws 27 on a horizontally swinging arm 28 which is held in position by the Fig. 5 is a plan view.`

spring 29 and the adjusting sleeve 30 with the screw 31 on the vertical rod 32 attached to the frame.

Wherever the word basket is used in the specification, it is intended also to refer to any receptacle that ina-y be made or manufactured by this machine.

Every time the cross-arm carrier 1 turns one quarter section, the protruding sliding shank 62 of the presser-foot 63 engages the ejector-plate 26 on the swinging-arm 28 and pushes it aside, tensioning the spring 29. After this movement the cross-arm carrier 1 descends carrying the former 2 with the finished basket, and the presser-foot 63 lowers its sliding shank beneath the ejector-plate 26 and thus releases the ejector-plate 26, so that the ejector-plate 26 will swing back into its former position above the top of the sliding shank 62. The lifting of the presser-foot 63 with the sliding shank 62 is prevented by the ejector-plate 26 during the following upward movement of the crossarm carrier 1 with the former 2. This movement simultaneously causes the ejection of the yfinished basket on to the conveyer 33.

The stopper 4 fits in the corresponding notches on the ends of the cross-arm carrier 1, holding it in position during the period the basket is being made. rIhe stopper' 4 is held by the hinge 5 and is operated by the cam disk 6 on the driving shaft 97.

The cross-arm carrier 1 is fastened by bolts 7 to the top plate 8 of the revolving sleeve 106, and is turned with the same.

The revolving sleeve 106 revolves in a bushing 13 of which the arm extension 14 is attached to the angle irons 15, which are fastened to the main frame. In the revolving sleeve and in the square boX on the bottom extension 16, the arbor-rod 9 is guided. rlhe lower part of this rod is square to keep it from turning with the revolving sleeve. The lifting and lowering of the arbor-rod 9 is effected by means of a rack 17 attached to the arbor-rod 9 engaging the spur .gear 18 on the shaft 19 which is turned by the gear 20 driven by the rack 21 connected to the oscillating link 60. This oscillating link 60 derives its movement from the cam 61 on the driving shaft 97. The shaft 19 is held by the bearings 22 on the bottom eXtension 16.

The revolving sleeve 106 is turned by a ratchet-lever 105, the arm of which is linked to the crank arm 104 on the shaft 93.

The arbor-rod 9 supports, lifts and lowers the sleeve 106 with the cross-arm carrier 1, for the purpose of picking up the slices, forming and ejecting the finished basket.

Therevolving sleeve 106 and the crossarm carrier 1 are kept in position on the arbor-rod 9 by the adjusting sleeves 10 which are fastened to the arbor-rod 9 by the set screws 11. `The cushion spring 12 is inserted between the top of cross-arm carrier 1 and the upper adjusting sleeve 10.

In Fig. 2 is shown the buffer 25with hinges 34 on all four sides, shaped in such manner as to allow an upward turning, but preventing the hinges from turning them below the horizontal plane, thus preventing the binding-strips from catching, or being pulled off, or loosened, during the upward movement of the former 2 and during the period of the ejection of the finished basket.

In Figs. 1, 3 and 5, is shown various parts of the bindingstrip bending frame of five bending links 35, 35a, 35h, 35c and 35d. The middle bending link 35 has a forward and backward movement through the two slots in which are located the pins 36, fastened to the frame plate 37. In the first movement to bend the binding strips around the moldblock 24, the live bending links move forward in line with the forward movement of the middle bending link 35, before the'bending links 35a, 35h, 35c and 35d commence to fold around the mold-block 24. The bending links 35, 35a, 35h, 35c and 35d are linked together by the hinge-pins 38. The pushrods 39 are connected with toggle-links 40. through the pin 41 in the push-rods 39 and working in the slots in the toggle-links 40. The toggle-links 40 are connected with the bending links 35a and 35d by the pins 41 so that the bending links 35L and 35d will turn easily. The folding of the bending links 35a, 35",.35C and 35d around the moldblock 24 is effected by the action of the pushrods 39 and the toggle-links 40. rEhe pushrods 39 are given a reciprocating forward and backward movement by means of the levers 64 (Figs. 1 and 5) keyed on the horizontal shaft 65 which is supported by the bearings 66, the levers 64 being actuated by the cam disk 69 (Fig. 4) on the main shaft 97, through the connecting rod 68 to the arm 67 which is keyed or held in place on the horizontal shaft 65. The bending link 35, while being folded around the mold- .block 24, slides up on the raiser 42, so that the end"-df the binding-strip which it is bending around the mold-block 24 will clear the other end of the binding-strip being bent around the mold-block 24 `from the opposite direction by the bending link 35, and so that, when the end of the binding-strip bent around the mold-block 24 by the bending link 352L is in place, the other end of the binding-strip bent around the `mold-block l 24 by the bending link 35L1 snaps intoplace in the end of the binding-strip bent by the i bending link 35a, so as to make a connection varying in length according to the lengthof the binding-strip. Y

The slices are-automatically fed from the hoppers 45 by suitable conveyers, in the drawings shown as endless belts 46 on the pulleys 46a on the shaft 46b and on the pulleys 46c on the shaft 46d, and the endless belts 47 on the pulleys 47a on the shaft 47 b and on the pulleys 47c on the shaft 47 d, and the endless belt 48 on the pulley 46e on the extension of the shaft 46d and on the pulley 47e on the extension of the shaft 47 d.

Also illustrated is shown simple lever 43, connected through the rod 44 with the swinging arm 70 on the shaft 93 which is rocked by the eccentric 98, eccentric-rod 99 and the crank-arm 100. The lever 43 through an adjustable connecting-rod 71 turns the spur gears 72 by means of ratchet wheel 73, and drives the shaft 46d, the shears 57 the feeder rollers 59 and the formingstrip bending rolls 81.

The carrier bars 44 attached to the endless chain or belt 4G engage the bottom slices and carry them one at a time on to the endless belts 47 over the support plates 49 to the stoppers 54 on the support plates. The support plates 49 are attached to the slice guides 50 by means of the brackets 51 and the screws 52. These slice-guides 50 are secured to the angle-irons 15 with the screws 5 3. (shown in Fig. l), and are suitably recessed to allow the descending former 2 to pick up the slices resting on the belts 47 and on the support-plates 49. In this movement of theformer 2 the first slice is picked up by the former 2 and carried around and placed upon the second slice at right angles so as to form what is known as a Maltese cross. With the slices in this position the former 2 also picks up the second slice and carries both around and places them upon the mold-block 24.

The Vbinding-strips are cut to suitable width by the shears 57 automatically worked up and down by `any suitable mechanism, out of sheet tin or other suitable metals or substances fed up on the plate 58 by the feeder rollers 59. As soon as the binding stripsv are cut off, they drop `into a channel and are forwarded by the mechanism of the shaping device 80 along the channel intov contact with the shaping rolls 81 which bend or form the binding-strips into a V or U shape, and until they are in line with and in front of the bending-links 35, 35a,

` 35h, 35 and 35d of the bending frame.

` thenY the cutter knife 82fis used to cut the In case the binding-strips are fed in from reels of tin or other suitable metals or substances by suitable mechanism, instead of cutting the binding-strips out of sheet tin,

.the cutter-knife 82 `shown in Fig. '1.`

`The cutter-knife 82 is shown mounted in theJ -holder 84 which is carried on the slide 85. Thisis raised and lowered on the ways 86 by the lever 87 and the rod 88v (Fig. 1) lwhichoscillates on the pin 89, ec-

centrically located on the main shaft 97. The .kinkingdies 88 (Fig. l), secured in' their respective die holders 92, derive Atheir movement from the up and down action of the lever 87, through the bar 91 secured to the hinge-rod 90 attached to the lever 87. There areas many kinking-dies 83 as are required. Simultaneously with the operation of the cutter-knife S2, the kinking-dies 83 are putting kinks or indentations in the inner side of the binding-strips at suitable points where it is to be bent or folded. Fig. 4 shows the V-shaped tin 95 in'the V-shaped space between block 94 and block 9G. These two blocks form the set.

IIhe binding-strips may also be fed from a reel of proper width, thus eliminating the necessary automatic cutting by shears as hereinbefore described.

`The shape of the mold-block can be changed so as to make or manufacture a` basket of any number of sides or of any shape desired. There this is done, the mechanism hereinbefore described can be so altered and added to so as to meet the different sided and shaped baskets, as for illustration the number of the bending links can be increasedv from five to whatever number of bending links is necessary to make the required sided basket.
