HENRY N. MANN, OF CHICAGO, ILLINOIS.

Specification of Letters Patent.

Patented Jan. 16,1912.

Application filed February 3, 1908. Serial No. 414,038.

To all whom it may concern:

Be it known that I, HENRY N. MANN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for Applying Cover-Retaining Devices to Receptacles, of which the following is a specification.

My invention relates to machines for applying cover retaining devices to covered receptacles, and particularly to a machine for applying to covered pails, or other receptacles, closure retaining and sealing rings.

One of the objects of my invention is to provide a simple and efficient machine, easily operated either by hand or by power, for applying to a pail or other receptacle, and its cover or closure, a peripherally continuous or uninterrupted ring seal, which when in place will retain the closure upon the receptacle and substantially seal the joint between the parts.

A further object of my invention is to provide a device of the character described in which the closure may be tightly and neatly applied, and the seal ring connected with the receptacle and closure uniformly and equally throughout its entire extent.

A further object of my invention is to provide such a device wherein the pail or other shipping receptacle is not set in motion or operated upon in any way detrimental to the contents thereof.

Other and further objects of the invention will become apparent to those skilled in the art.

In the drawings, wherein I have shown an embodiment of my invention; Figure 1 is a side elevation of the machine in operating condition; Fig. 2 is an enlarged vertical section of part of the apparatus shown in Fig. 1; Fig. 3 is an enlarged detail of the toolcarrying head; Fig. 4C is a section on line 44 of Fig. 5; Fig. 5 is a section on line 55 of Fig. 4; Fig. 6 is a section on line 66 of Fig. 5; Fig. 7 is a section on line 77 of Fig. 6; Fig. 8 is a sectional detail on line 88 of Fig. 2; Fig. 9 is a fragmentary plan view of the pail centering devices on the base; Fig. 10 is an enlarged detail of one of the centering clips, and; Figs. 11 and 12 are enlarged details, showing the sectional configuration 'of the seal ring for the application of which the illustrated machine is designed, before and after application to the receptacle.

Throughout the several figures like numerals of reference refer always to like parts.

In general my invention contemplates the provision of a frame comprising a base and bridge suitably spaced apart, the base being for the reception and support of a pail, and preferably provided with means for centering the pail or other receptacle to be operated upon, and the bridge carrying a vertically movable platen adapted to accurately position and temporarily hold upon the pail a cover and a sealing ring to be secured in position, the structure movable with the platen carrying suitable tools, movable with respect to the platen, to deflect portions of tlie seal ring sufliciently to effect attachment of the ring to the receptacle in a desired manner, means being provided for the operation of said ring deflecting tools manually or by power.

In the specific embodiment of my invention shown, 20 indicates in general a frame, comprising a base 21 for aflording support to a pail or other receptacle, upright posts 22 and a bridge 23 supported upon said posts at a suitable elevation above the base 21, and providing preferably an upright center bearing extension 24:. The base 21 may be provided with centering devices, herein shown in Figs. 9 and 10, as a pair of angular clips 25, having foot portions slotted as at 26 and engaging bolts 27 for securing the clips in various positions of radial adjustment for the proper centering of a pail or other receptacle. The bearing extension 24:, on the bridge, is provided with an internal vertical slide way 28, overlain by a cap 29 forming the bearing for a hand wheel 30 carrying screw 31, which depends into the slideway 2S, and carries a movable platen or press member of the device. The platen member, generally indicated at 32, is of suitable shape and extent to overlie the receptacle to be acted upon, and is preferably provided around its lower surface with a raised rim or elevation 33, having therein an annular depression 34, for a purpose to be described. The platen 32 is provided with a stem 35 extending up into the slideway 28, and preferably secured against rotation therein by a feather connection indicated at 36, the stem 35 being internally screw threaded for enga gement with the screw 31.

The tools for attaching the seal ring to the receptacle are carried by the platen in its vertical movement, but are in operation movable with respect to the platen as a station'- ary support, and to this end I provide upon the stem 35 a rotatable carriage, preferably in the form of a hand wheel, as indicated at 38, said hand wheel having one of its spokes made sufiiciently wide, as indicated at 38 in Fig. 8 and Fig. 2, to accommodate a slide-way 39, in which is slidably mounted for radial adjustment a tool carrier 40, said tool carrier being composed of a stem part 41, fitting in the slideway 39 and a body part 42. The radial arm 38 is provided with a slot 43 and a bolt 44 connected to the stem 41 of the tool carrier, passes through said slot, so that the tool carrier may be radially adjusted as desired with respect to the arm 38. Obviously by manually rotating the carriage or hand wheel 38, the tool carrier is rotated with respect to the non-rotatable platen, and I provide means whereby power may be employed for effecting such rotation if desired. For this purpose the hub of the carriage is provided with a reduced extension 45 on which is mounted a friction wheel 46, and upon the bridge 47 is provided a driving gear mechanism preferably comprising a power shaft 47, carrying fast and loose pulleys 48, 49, and a beveled gear 50, the shaft 47 being mounted in a suitable fitting 51, which also affords vertical'support to a counter-shaft 52 vertically arranged and hearing on its upper end a beveled gear 53 intermeshing with gear 50, the lower end of said shaft being laterally movable and carrying a friction pulley 54, which may be thrown into or out of driving engagement with the friction wheel 46, by means of a shipper lever 57, pivoted as at 58 in a fitting which also affords a guide 59 for the lower extremity of the shaft 52, the free end of the lever 57 being connected by a shipper bar 60 with the shaft 52. By this arrangement it will be observed that considerable range of movement is afforded the wheel 46 which shifts its position vertically with the platen, without disturbing the gearing relation of the driving devices.

The tool carrier 40, as best illustrated in Figs. 3 to 7, is provided in its under surface with a dove-tail channel 62, in which may slide a correspondingly shaped portion of a tool-carrying head 63. The head 63 is provided in its top with a suitable laterally extended recess 64, in which engages an eccentric 65 mounted on a stem 66 extending to the top of the tool-carrying body 42, and provided with an operating handle 67, so

65 and the walls of recess 64. The tool or tools arranged in the head 63 are of suitable character to so deflect a thin metal ring as to effect a juncture thereof w1th the body of receptacle to be sealed, in any desired fashion, as by inturning or indenting the metal for engagement w1th a suitable part of the "receptacle. I prefer that the tools shall be spring pressed to the work, and to this end I provide in the head 63 tool-holders having a limited range of movement in the head and pressed forward or toward the work by suitable springs.

In the specific construction shown 70 and 71 indicate companion tool-holders arranged side by side in parallelism in a common horizontal plane, and alike in construction, so that one thereof alone need be described. The tool holder 71 is preferably a rod, having an end portion reducedqto form a finger 72 upon which the tool is mounted for rotation on a vertical axis, the rod 71 having an enlarged portion 73 at its inner end recessed as at 74. The rod is seated in a counterbored recess 75, in the head 63, the recess 75 being overlain by' a cover plate 76 through which projects an adjusting screw 77, bearing against the plate 7 6 affording a seatfor a strong coiled spring 79 at its opposite end seated in a recess 74. The spring 79 normally holds the tool-carrier projected as far as possible beyond the head 63, but permits yielding thereof when necessary. Rotation of the tool-holder with respect to the head is prevented by a suitable pin and slot connection 80, as shown in Fig. 7. For the particular operation hereinafter described, the two tool- holders 70 and 71 carry respectively a wheel 82 of frusto-conoidal shape and a star wheel 83, each such wheel being mounted on a vertical bolt 84'and secured to the finger port-101172 of its carrier.

As thus constituted the machine is particularly adapted for sealing candy pails and likepackages, consisting each of a suitable receptacle A and a cover B overlying the mouth of the receptacle, with a seal ring C of the construction illustrated in Figs. 11 and 12. Such seal ring preferably comprises a peripherally uninterrupted, or continuous band of metal preliminarily formed up to present in cross section, as shown in Fig. 11

a vertical part c for encircling the edge of the cover, an inturned annulus 0 downturned somewhat as at 0 at its inner extremity to form a bead overlying a border portion of the cover, and an outwardly flaring skirt portion 0 which facilitates the placing of a band on the receptacle.

In the operation of the device the receptacle, properly packed with the ingredients which it is to contain, is placed upon the base of the machine and centered by abut ting its lower part, or base, against the centering members 25, the cover is laid in position on the top thereof and the ring seal slipped on over the cover as far as it will conveniently go. Now the handwheel 30 is rotated to drive down the platen 32, the recess 34 in the rib 33 whereof receives the bead c of the seal part, and forces the sealing ring home into tight engagement with the top of the cover. I have found that even if the cover be badly warped the pressure thus applied evenly throughout its periphery, flattens the cover down upon the receptacle and presses the downturned edge 0 of the bead 0 into intimate engagement with the wood of the cover. This done the metal-inturning tools will have been brought to proper vertical position, as the tool carrying head has vertically moved with the platen and is constantly positioned in a proper vertical plane with relation to the platen, to act on the proper portion of the sealing ring.

By means of the eccentric the toolcarrying head 63 is forced radially inward sothatthe tools 82 and 83 are brought yieldingly, but under heavy pressure of their springs 7 9, into engagement with the skirts 0 of the face. Now, by hand or by power, the part 38 is rotated, carrying with it the tool, in such direction that the tool 82 precedes in rotation the tool 83, the tool 82 acting to roll the flaring skirt of the band into intimate contact wit-h the staves of the receptacle, and the tool 83 immediately following it indenting the lower edge of the inrolled band into the body of the staves to effectively attach the sealing ring to the receptacle body in such manner that it both retains in place the cover and practically seals the joint between the cover and the receptacle body A.

WVhile I have herein described in some detail a specific embodiment of my invention which I believe to be new, and which I have found to be practical in operation, it will be understood that numerous changes in the specific embodiment may be made without departure from the spirit and scope of my invention.
