Specification of Letters Patent. 7 P t t d Ju 27 19 1 7 Application filed January'fll), 1908. I Serial No. 411,804.
To all whom it may concern.
Be it known that I, FRANCIS C. OsBonN, a citizen of the United States, and a resident of Detroit, in the county of Wayne and State of Michigan, have invented a new and Improved Container Body Forming Machinc,'of which the following is a specification.
My invention relates to means for reducing the diameters of the ends of tubes which are intended to form the body portions of cylindrical receptacles-in order that when the heads are slipped over the ends of the tubes the flanges of theheads Will'not project laterally beyond the bodies of the receptacles.
The object of my invention 'is'to. provide a machine which will rapidly "and automatically reduce the diameter of the tubes formed from fibrousmaterial or metal so as to adapt such tubes for forming the body portions of cans or other receptacles.
My invention consists in tube holding means in combination with means for reducing the diameters of the ends of the tubes.
It further consists in the combination of an expansible mandrel, and means to'reduce the diameters of the ends of tubes,- the re ducing means and mandrel being revoluble the mandrel and discharge them from the relative to each other.
My invention further consists in the com binatlon of a tubecarrier means for feeding the tubes thereto, means to hold the tubes,-
means to reduce the diameter'of the ends of from the tube carrier after the ends of the same shall have been properly reduced.
In the accompanying drawings, Figure '1 is a vertical, longitudinal, central, cross section of the machine. Fig. 2 is a plan of the same. Fig. 3' is a vertical cross section on the line A-A. of Fig. 1. Fig. 4 is a cross section of the tube mandrel and reducers in the same plane as. Fig-1 on'a larger scale. Fig. is a view of a cylindrical box, part of it being broken away.- Figs. 6 and 7 are views of the'lower sides of the main operating cams. Fig. 8 is afview of the feeding and discharging mechanism on the line B' B of Fig. 1. Fig. 9
} upon the sine of the machine. the tubes, and means to remove the tubes is an end view of the frame of the machine. Fig. 10 is across 3 section on the line CC of Fig. 1.
Similar reference. characters refer to like parts throughout the several views.
Cylindrical boxes having cups slipped over the ends thereof are very common.- It has always been difficult to properly paste labels on these boxes because'the flanges of the heads or ends projecting beyond the cylindrical surfaces of the body. My improved machine is adapted toso reduce the diameters of the ends of the tubular bodies of this type of boxes that the flanges of-the heads or ends may be so fitted to the reduced portions, that the outer surfaces of the flanges and ofthe body willbe practicallv one continuous cylinder.
My improved machine consists of a pair of frames connected by longitudinal bars and a central shaft upon which the reducing means and the tube carriers are mounted. The reducing means each consist of an eXpa-nsible mandrel adapted to receive the tubes from the tube carrier and two cup shaped reducers which are adapted to revolve inopposite directions over the ends of the tubes to reduce the diameters of the same. Means are also provided to remove the finished tubes from machine. The tube carrier is provided with pockets for each set of reducing means, the
number of such reducing means depending 2 at their tops, a main shaft 3, and two connecting bars 4. Revoluble on the main shaft 1 3 are three sleeves 5,6 and 7. A pulley 8 on the sleeve 5 and-the pulley 9 on the sleeve 7 are 'driven in opposite directions at the same speed by belts from the same counter shaft.
Extending across the shafts -1is aframe 10 in-which is'mounted a shaft 11. On one end of the shaft 11' is a gear 12 which meshes with the pinion 13 's'ecu'red't'o the sleeve 7.
' On the other end of the. shaft his a pinion.
14 which meshes with the gear 15 that is secured to the sleeve 6.. Secured to this sleeve 6 are the tube carrier 16 and the disk 17. As the gear 15, the disk 17 and the tube carrier 16 are all rigidly connected together. there is no possibility for them to get out of line with each other.
Secured-to the gear are the brackets 18 which carry the tubes 19 as shown in Fig. 1.
Secured to the disk 17 are the brackets 20 in which are slidable the. shafts 21. Slidably and revolubly mounted on the tubes 19 are the sleeves 29, on one end of which are secured the pinions 21? which mesh with the gear 22 secured to the sleeve 7. On the other end of these sleeves are cup shaped reducers 23, preferably f om hardened tool steel. On the ends of the shafts 21 are simivolved by means of the gear 22. The shaft 21 is provided with a key 25, and is slidable through and revoluble with a pinion 26 which meshes with a gear 27 on the sleeve 5. By these means, (the gears 27 and 22 revolving in opposite directions and the disk 17 and-gear 15 being connected together) the reducers will revolve around the shaft 3 in line with each other.
Referring now to Figs. 4 and 10 it will be seen that the tube 19 extends into the collapsible mandrel and has disks 30 secured, one to its outer and one toits middle portion. These disks extend laterally to form cylinders 31. Between the disks 30 the collapsible mandrel is supported, and consists of four parts 32, the ends of which parts are guided between the'disks 30, and are provided with guide screws 33 which are movable in the slots 34 in the disks. Springs 35 connect to these parts 32 and to the tube 19.
The ends of these parts 32 have tongues 36 provided with beveled edges, which enter slots 37 in the tube 19. Longitudinally .movable in the tube 19 is a plunger 38 having conical portions 39 adapted to engage the inclined edges of the tongues 37. When this plunger 38 is moved outwardly, that is will be expanded, and when tl to the left in Fig. 4, the mandrel parts 32 1e plunger is retracted, the mandrel will collapse under the action of the spring 35. mandrel is shown in expanded position. The disk 40 at theend of the plunger prevents the same from slipping out. The tube 41 shown in Fig. 4 is slipped over the mandrel inv a manner which will be explained later. -The plunger 38 is then moved out, expanding the mandrel to tightly engage In Fig. 4 the the inner' side of the tube. The two cups 23 and 24 arethen moved toward each other and as they revolve they will slip onto the ends of the tube and reduce its diameter in the manner shown in Fig. 4. As these cups revolve in opposite directions, there will be little tendency for the tubeto turn on the mandrel. The inner edges of the cups are slightly tapered so that they will engage over the ends of the tubes. After the cups have revolved over the ends of the tubes a sufiicient number of times to insure the reduction in dia'meter remaining permanent, the cup 23 and then the plunger 38 are with drawn thus first freeing the tube from the cup and then freeing it from the holding pressure of the mandrel. The cup 24 1s then Withdrawn carrying with it the tube from the mandrel.
The mechanism forcarryingthe tubes and for operating theloollapsibl'e mandrel and the reducingmean's are as follows: The tube carrier 16 is formed by two disks 43 having hubs 44 secured to the sleeve 6. The tubes travel down a guide .47 and are permitted to fall into the notches cut in the disks 43. To
position the tubes spring held pins 48 are the spring held rods 50, on the outer ends of which are secured the flat fingers 51. The tubes falling into the notches in the carrier are positioned by these pins and fingers as shown by the dotted lines in Fig. 1. The
tubes are then pushed onto the mandrel as Y follows. Mounted on the rods 4 is a frame 53 which supports a. bracket 54 on which is mounted a drum 55 which surrounds the sleeve 5. Secured to this drum are two cams 56 and 57 which are adapted to engage the knobs 58 on the outer ends of the shafts 21 to move the cups 24 in and out as these knobs travel around the drum. It will be seen in Figs. 1 and 2 that when a shaft 21 is at the upper side of the drum, the cu 24 is drawn back to permit a tube to fall into a notch in the carrier. the carrier and disk 17 causes the cam 56 to push the shaft 21 inwardly until the cup 24 'engages over the flange 31. In this movement the tube is pushed out of the notch in the tube carrier onto the mandrel, the spring held fingers 51 and pins 48 permitting the beveled edges of the cup to push them back. After the revolving cup has accomplished its phrpose it is withdrawn by. the cam 57, the cup carrying back with it the tube into the notch in the tube carrier from whence it is ejected as will be described later. To prevent the tube being retained by the cups 24 Further rotation of after it has reached the properposition'in the carrier, an ejecting disk 59 is mounted in the cup 24 and connected to the plate 60 I v seams by means of pins 61'. As the cup 24: is reach- .ing the outward. limit of its movement the plate will contact with the disk 1'? and force the ejecting disk outward as-sh'own in the upper part of Fig. 1.
' Secured to the frame 10 and cross shait2 is a bracket 63 which carries the drum 64. T his,drum has three cams secured to it, the cam 65 to move the cup 23 in and out, and the cams 66 and 67 to operate the plunger From Fig. 2 it will be seen that until the end of the first quarter of the revolution of the sleeve 6,the plunger 38 and sleeve 20 are not moved longitudinally, that during this time the cup 2+1 is moving the container body over the collapsible mandrel. At the end of the first quarter and beginning of the second quarter, the cam (36 moves the plunger 38 inward, expanding the parts 32. During this second quarter the cams 56 and 65 {we Figs. 6 and 7 are moving the cups 23 and 24 toward each other, which cups will reduce the diameters. of the ends of the container body 41 as shown in Fig. .4, the parts reaching the positions shown in Fig. 4 just before the end of the second half. The parts remain in this position for a short time and then again move; the head 68 at the end of the plunger 38 passing the cam 66 and engaging the rear face of the cam 67. While the springs 35 and the inclined ends of the tongues 36 usually push out the plunger, the cam 67 is a good safety de vice. The cam 65 is chiefly a projecting flange which tits in a groove 69 in the hub of the gear 21. The inclined portioriTO of this cam will withdraw the cup 23 immediately after the end of the second haltoi the revolution of the tube carrier. The tube being free from the cup :28 and the mandrel havin collapsed, the act-ion or the cam 57 on thelhead 58 on the end of the shafti-l will carry the tube baelrinto its notch in the tube carrier.
1i nstead of forming the plunger 38 solid. a spring .Bllfiflflitff he employed as shown in the upper part of Fig. 1. by means of which slight differences in the internal diameters oi the tubes are provided for.
To eject the finished tubes, a sleeve 70 is loosely mounted on the shat: 2 and is held in position by the pin 73 and by the spring 71. one end of'which is secured to this sleeve, and the'othcr to'ihe collar 72. A finger 74 projects into the paths of the pins 75 carried by the camel (5 ohthe inner side of the gear. Arms 77 (see Fig. 3) project forward from the collars 78 on the sleeves 70, which arms are not shown in Fig. 1, being cutaway for the sake of r-lcarness. The pins are so positioned thatthe arms 7'? will be'drawn back to the. position indicated by should it fail to move.
' remain until a'notch receives them.
dotted lines in Fig. 3 and released just as a tube is brought to the position there indicated, the action of the spring 71 causing the arms to snap the tube out of the notch in the carrier 16 and out of the machine.-
. While the finished tube is usually carried oil the-mandrel-b means'of the cup 24, means are provide for removing the tube A frame is secured to' the shaft 2, comprising end pieces 80 and longitudinal members 81 and 82. The guides 47 are secured to the longitudinal members. A shoe 83 is slidable on the bar 81 and is normally heldto the right by thespring 84. Projecting down from this shoe is a. pin 85, normally in the path of-the cams 76 on the gear 15. An arm 86 projects rearwardly from the lower side of the shoe (Fig. 8) and carries a finger 87 which projects through a slot in the rear end of the stripper'arm 88 which is pivoted on the bar 81 at 89. The outer end of the arm 88 is broken oil in Fig. 1 for cl-earness.
WVhena cam C 6 Jasses the in which is secured to the shoe 83 that is slidable on the longitudinal member 81, the pin and shoe will be moved to the left, and thereby the upper end of the stripper armSS which is pivoted to the member 81 will be swung to the left through the action of the pin 87 on the arm 86 that is secured to the shoe v 83, and the lower odd to the right (Fig. 2) and will remain at the right end of the mandrel until the cam passes the pin 85 when the spring 84 will swing the arm back to normal position. This occurs just the finished tube-reaches the position indicated by dotted lines in Fig. 3, or just after the arms 77 have been swung back through the action of a pin 75. I r
'The tubes to be formed roll down the inclined guides 47 and fall onto the edges of the disks 43 of the tube carrier where they They are prevented from rolling down by the arms 77. To prevent the edge of a second tube from getting into the path of a cup 24 during its movement to place the tube just before it over the mandrel, means are provided for lifting the hecond tube out of the pathof the cup 24.. A light shaft 90 is pivoted in the arms 77 and a finger91 is secured to one end of this shaft inthe path of the pins 92 on'the disk 17 Other fingers 93, similar to finger 91 are secured to this shaft so "that when a pin 92 swings the finger 91 rearwardly, the fingers will engage said second tube and'lift it out of the way of the cup 24. A spring 94 holds the parts Plates 95 secured to Having now explained my construction, what I claim as my invention and desire to secure by Letters Patent is 1. In a tube forming machine, the combination of a frame, atube carrier. c0llapsible mandrels, reducing means, and driving mechanism for the various parts, whereby the tubes are slipped onto the mandrels, the mandrels are expanded, the reducers engaged over both the ends of the tubes simultaneously, the mandrels collapsed, the tube reducers withdrawn and the finished tube discharged from the machine.
