UNITED STATES PATENT OFFICE LEWIS B. WIN TON, OF GREENWICH, CONNECTICUT, ASSIGNORQBY MESNE ASIGN' MENTS, T AMERICAN SEALCONE CORPORATION, 0F N EW YORK, N., Y., A CORPORATION OF NEW YORK RECEIPTACLE'BEADING APPARATUS Application led September 24, A1930. Serial No. 483,982.

rllhis invention relates to a lubricating system particularly adapted to be used in connection with receptacle heading apparatus and of such construction and arrangement as to be readily applied to existing heading apparatus.

The receptacle heading apparatus to which thepresent invention is adapted to be applied, is embodied in a machine for making paper receptacles, as disclosed in Letters Patent #1,628,074, issued May 10, 1927, and by which a sheet of paper is formed into a conical tubular body into one end of which a flanged paper disk is inserted with the disk flange extending outwardly in con tiguous relation to the wall of the body and secured in the body by rolling togethergthe disklange and contiguousportion of thc/body by spinning apparatus, there beinggtwo of such apparatus of substantially the same design and structure to primarily break down and then roll the disk flange and body into securing and intimate relation. i Each apparatus comprises a revolubleY spinning head `adapted to be reciprocated axially toward and away from the receptacle body and inserted bottom disk and carrying rotatable rollers having a V-shaped recess about the periphery to engage the edges of the disk iange and contiguousportion of the receptacle body upon the reciprocation of the head toward the positioned receptacle, which engagement will cause the rollers to rotate at high speed due to the rapid rotation of the head. lThe rollers are rotatably mounted on studs spaced about and projecting from the periphery of the head with a close fit to assure an even rolling by maintaining the roller recesses in alinement. Due to' this close fit and the speed at which the rollers are rotated heat of a'high temperature is -created causing the material of the rollers and studs to expand and freeze one tothe other preventing rotation of the rollers and resulting in the rollers sliding about the disk flange and receptacle body, not onlycausing Wear of the rollers but also scorching of "the material of the receptacle body and bottom and rendering the receptacle useless.

I tis the 'principal object of the invention to prevent the frequent replacement of the rollers and the rendering of the 'receptacles useless caused by this faulty structure of the present heading apparatus by providing automatic lubricating means for the bearing surfaces between the rollers and supporting studs which is simple in structure and inexpensive to apply to new or existing apparatus.

The embodiment of the invention comprises a reservoinfor oil ixedly mounted relative to the reciprocating head and adapted to feed oil bygravity to an oil carrying well arranged in the head in communication with the oil reservoir in all positions of said head, the oil in the oil carrying wcll being delivered to the bearing surfaces be tween the rollers and studs by ducts arrangcdgin the studs in communication with said well and opening to the bearing surfaces of the studs.

. the holders 10 being successively positioned,

as at a, by the intermittent movement of the disk relative to a mandrel (not shown) about which a blank is wrapped to form a conical body, the formed body being delivered from the mandrel into a holder stationed relative to the mandrel by the carrier disk with the end portion of the receptacle body of largest diameter extending from the holder, as at 13, the sections of the holders being separated by means carried by the disk 11 to facilitate inserting the formed receptacle body therein.

Upon the next sucessive movements of the disk 11 the holders are positioned at station Z), and then to station c relative to means (not shown) to form a flanged disk and position the same into the extending end of the receptacle with the flange extending voutward from the disk in cont1guous relation to the Wall of the extended receptacle end. The

holders with a flanged disk engaged in a body therein are then moved to position d relative to the -primary or first heading apparatus, as shown in A in Figure 1, where the disk flange and receptacle body are primarily rolled together or interfolded. Upomthe next movement of the disk 11 the holders are positioned, as at e, relative to the second or nal heading apparatus, as indicated at B, which is of the same structure as the primary heading apparatus. The holders are then successively moved to positions f and g and the receptacles lelivered from the holders at the latter staion.

.Each of heading apparatus comprises a spinning head (indicated in a general way at H in FigureV 1,) rotatably mounted on a standard S fixed upon the table 12 inalinement with the holders at stations d and e. The head is fixed to a shaft 14 rotatably and slidably mounted in a bearing at the top of the standard and retained by a cap 15, arranged as shown in Figure 3. The spinning head is rotated by a motor M the drive shaft 16 of which is coupled to the head carrying shaft 14 to permit of sliding movement of the shaft 14 toward and away from the receptacle holders by a perforated collar 17 fixed to the shaft 16, pins 18 extended from an annularly recessed collar 19 fixed to the end of s haft 14, slidably engaging in the perforations 1n colla-r 17. The spinning heads H are actuated toward the receptacle holders during the periods of rest of the holder disk 11, by levers 20 arranged with a bifurcated end 21, Figure 3, the legs of which engage at opposite sides of the vcollars 19 with rollers 21 mounted on pins fixed in the bifurcation legs engaging in the collar recess. The lever 20 forv head B is fixed at the opposite end on a shaft carried by the standard S, and is reciprocated from the drive shaft 22 of the receptacle making machine through a cam wheel 23 fixed to shaft 22 and a cam following roller 24 in the cam groove of Wheel 23 carried by an arm fixed to the shaft 25. The actuating lever 20v for the heading apparatus A is connected with shaft 25 to be reciprocated in synchronism with the-lever 2O of heading apparatus B by an arm 26 fixed to shaft 25 having pivotal connection 27, With an arm 28 fixed on a spindle 29 rotatably mounted in the standard S of the heading apparatus A and to which the lever 20 of said heading apparatus is fixed, rocking of shaft 25 to move the spinning heads toward the positioned receptacle holders will rock the pivotal connection 27 of the arms 26', 28 in a downward direction thereby moving the bifurcated end of the lever 20 toward the standard S. The motor of the heading apparatus A is supported from the table 12 in spaced relation theret0 to permit the mounting of the rook shaft 25 on the table by blocks at the ends of the base of the motor, as lindicated in dotted lines at 30 in Figure 1. The spinning heads H are yieldingly urged toward the holders by a spring 8O fixed to the bifurcated ends 21 'of the levers 20 and the standards S, as shown `in Figure 2. Each of the spinning devices comprise a head 31 fixed to reduced ends of shafts 14 in abutting relation to an annular shoulder 32 by a perforated disk 33 engaging in an enlarged recess 34 in the outer face of the head and a screw 35 passed through the disk perforation and threaded into the shaft. Rollers 36 having a V-reeess 37 about the peripheral edge for spinning engagement with the edges of the disk flange and receptacle body are rotatably mounted in diametrical opposite pairs on the side of the head by studs 38 having a reduced end portion for engagement and mounting in. bores 39 extended into the'head 31 radially of the shaft 14, as shown in Figure 4. The studs are secured and held against rotation in the bores by screws 40 threaded in the head 31 engaging in a recess 4l in the reduced end of the studs, as shown in Figure 5. The rollers are` retained on the studs by providing the studs with heads 42 at the free ends with `interposed ball bearings 57. IThe rollers with screws 46 threaded through the ring engaging the stud heads 42. To retain the bottom of the receptacle in alinement with the spinning rollers 36 during the spinning operation an annular plate 49 is mounted on the outer face of the head 31 by the screws 40, the surface of the plate being recessed at the juncture of the face and periphery of the plate, as at 50, to engage the inner edge of the rolled portion of the closure disk and receptacle body and maintain the receptacle in alinement with the headingrollers.

The bearing portions of' the studs 38 upon which the rollers 36 are rotatably mounted are of a diameter relative to the bores of the rollers that the rollers have no lateral movement when engaged With a closed receptacle end to assure maintaining the rolling recesses 37 of the rollers 36 in alinement with each other. By this method of mounting the rollers on the studs, heat of a high temperature is developed due to the speed of rotation of the roller carrying head necessary to properly crimp and roll together the material of the disk flange and the receptacle body, and to also produce a large number 0f receptacles during a given period of time. Theheat thus developed causes expansion of the material of the rollers and supporting studs which will cause the material to seize and prevent the rollers from rotating, thereby effecting a rolling together of the closure disk flange and the receptacle body by only a portlon of the roller recesses 37 and a calendering action which will cause undue wear and render the rollers useless. This will also develop sufiicient heat to scorch and burn the material of the closure disk and receptacle body rendering the receptacle useless.

To overcome the overheating of the bearings of the rollers it was necessary to stop the operation of the machine after short periods to oil said bearings by hand thereby reducing the number of receptacles produced and capacity of the machine considerably. To overcome this disadvantage of overheated bearings without stopping the operation of the machine means have been provided to automatically lubricate the -end communicating Vwith a recess 52 in 'isA extended laterally from and communi- Cates with the duct 51 and opens to the bearing surface of the stud at a point intermediate. the ends of the roller supporting portion thereof. The oil is supplied to the ducts from an oil carrying well in the spin-I ning head 31 in the form of an annular recess 54 Aarranged in the inner face of the head with the Walls thereof extending in an oblique direction toward the sides of the head whereby a quantity of oil by the action of centrifugal force through the rotation of the head is retained in the recess for delivery through perforations 55 into the stud recesses 52' and the ducts 51 to the i balls in the chamber 56 interposed between the rollers and studi heads.

The oil is retained in the recess 54 for the entire circumference thereof through the action of centrifugal force induced by the rotation of the head and to prevent the oil from leaving the recess the inner wall of the recess is of less height than the outer wall, the outer wall being in the form of an annular flange 59 in spaced relation with a hub portion 60 of the head 31 which forms the inner wall, the space between the fiange 59 and hub 60 constituting the recess 54, as shown in Figure 5.

The oil is retained in the 011 well 1n the lhead at a predetermined level and in suflicient quantity to assure lubricating all of the friction surfaces by an intermlttent supply of oil from an oil reservoir or container 61, Figures 2 and 3 havmg a filler opening with a pivoted closure 62 and a valved controlled outlet through a reduced tubular portion, as at 63, the valve being adapted to be actuated by a lever 64 pivotally `mounted at the top of the reservoir, or the valve may be of the automatic type perrriitting an intermittent flow of l1qu1d. rlhe reservoir is fixed on the standard S by securing the reduced tubular portion 63 1n a collar 65 at the top of a housing member 66 fixed relative to the bearing cap 15 on the standard S by a pair of perforated` ears 67 extending laterally from and integra-l with alined sleeves 68 fixed 1n and extending from the end walls of the housing, as shown in Figures 7 to 9, inclusive, the ears being mounted on the standard S by the bolts which secure the cap 15 to the standard, as shown in Figure gw To connect the oil reservoir to e'oil well 54 in all positions of the spinning heads H relative to the closed receptacle end oil connecting means is provided to reciprocate in synchronism with the reciprocatory movement of the spinning head carrying shaft 14, and comprises a rectangular body 69 having an oil receiving pocket 73 and slidably mounted within the housing member 66 in alinement with and below the reservoir outlet 63 by rods 70, 71 fixed in and extended from Aopposite sides of the body slidably engaging in the housing sleeves 68 with the free ends of the rods projecting beyond the sleeves.

. The rod 70 is pivotally connected at the free end thereof to the upper end 21 of the lever 20, as at 72, whereby thel reciprocatorv movement of the shaft 14 is imparted to the body 69. The oildelivered from the reservoir 61 is received in the pocket 73 in the body 69 which is of such size to receive the oil from the reservoir in all the reciprocatory adjusted positionsV of the oil receiving body, and the oil is fed from the pocket 73 to the oil well 54 by gravity through a bore or duct 74 leading through and from the body 69 in communication .with a bore extended through the supporting rod 71, the projected end of rod 71 being arranged with a spout or nozzle 75 in communication with the bore of rod 71 and extended laterally of the rod in juxtaposed relation to the standard S at the rear of spinning head 31with the outlet end thereof bent downward to extend into the lowermost portion of the oil well adjacent the flange 59, as shown in dotted lines in Figure 5, this position of the nozzle relative to the oil well being maintained due to` the reciprocatory mounting and positive connection of the oil receiving pocket 73 with the shaft 14. The bore 74, the -bore in the rod 71 and nozzle form a conduit reciprocatory in synchronism with the movement of the head through which oil is automatically delivered by gravity to the oil well from a source of supply. To facilitate the assembling and cleaning of the oil receiving body 69 the exposed face of the housing 66 is open, as shown in Figures 2 and 7, and to prevent oil from splashing from the housing during the operation of the apparatus, the opening is enclosed by a cover plate 76 releasably secured to the housing by screws 77 passed through perforations at the corners of the platey and threaded into bosses 78 at the corners of the opening to the houslng.
