TAYLOR, 0F MOUNT VERNON, NEW YORK, ASSIGNOR TO THE BORDEN COM- PANY, OF NEW YORK, N. Y., A CORPORATION OF NEW JERSEY MACHINE FOR APPLYlING CEMENT TO CAN TOPS Application mea February 21, 1929. v'serial -NoauimaY The invention relates to 'an improvement in machines for applying cement to can caps and more particularly to an improvement in machines for applying liquid cement to the 5 fiat annular ange of the caps for clos-` ing the central filling hole in the top ends of cans adapted to contain condensed milk and the like. The liquid rubber or other cement is applied to the cap for the purpose of gg forming a hermetrically sealed joint between the cap and the edges of the hole in the can. One object of the invention is to rearrange and simplify the construction and mode of operation of machines of this type to produce a compact, durable and high speed machine or accurately applying just the right amount of liquid cement to the can cap. Another object of the invention is to arrange the parts of the machine so they may be easily taken apart for cleaning.. A further object of the invention is to provide a rotary machine of this character with improved means for receiving and discharging the caps which have been operated 4upon. These and other objects of the invention which will appear as the description proceeds are accomplished in the improved machine for ap-l plying cement to can caps hereinafter fully described and particularly pointed out in the appended claims.

VThe improved machine for applying liquid gum or cement tocan caps as illustrated in the drawings is of the rotary type and in the illustrated embodiment comprises siX units, that is .to say, six cap supporting spindles and corresponding thereto s iX valves for controlling the feed of cement to the capsl supported on and rotated by the spindles. As a cap is fed into the machine for the gumming operation through the chute, the lower curved end of which is indicated at 15, a gummed cap is discharged from the machine and is received on one or the other of two

conveyor belts

16 and 17 which carry the gummed caps away from the machine, preferably into a .drying chamber.` The caps treated inl the machine consist of a dish-` shaped body portion 18 and an annular flanged part 19. The dish-shaped part 18 is adapted tofit into the hole in the central part .of the top of the can and the gum or cement is coated on the under surface. 2O

eso`

swaged into locking engagement with the lli edges of the hole to close the hole and keep the contents of the "can hermetically sealed. The can caps are supported upside down for the gumming operation, as shown in Figs. 3 and 6 on the upper enlarged ends of the spindles or plungers 22 vertically and rotatably supported in the

annular flange sections

23 and 24 ofa carriage 25 contracted at its lower end to form the trunnion 26 journaled in the central part of a table 27 supported by the legs 28, the lower extremity 29 of the contracted portion of the carriage being journaled in the bracket 30 secured to the underside of the table 27. The carriage 25 is rotated in a clockwise direction from a shaft 31 (driven from any convenient source of power) on which is mounted a worm 32 which meshes with and drives the worm gear 33 fixed on the lower end 26 of the carriage. While the carriage 25 is rotating to convey the caps from the point at which they are received to the point at which they are discharged, the spindles 22 which support the caps on their upper ends are individually rotated in unison, and for this purpose each spindle 22 carries on its lower end a gear 35 which meshes with an annular rack 36 supportedin the upper inner edge of a ring 37 secured to the top of the table 27.

The caps to be gummedv are fed by gravity down the chute the lower extremity 39 of which forms a platform ,which extends over the upper edge of the flange 23 of the carriage and in close proximity thereto, as indicated in Figs. 2 and 4. The caps land on4 the platform 39 upside down. Thechute is provided with the guard rail 38 to keep the caps in the chute until they are delivered onto the platform. The weight of the caps in the chute pushes the lowermost cap across the platform and presses it against the edge 40 of an annular shoulder 41 formed on the carriage 25 above the flange 23. In the shoulder.

41 are cut arc-shaped openings 42 in alinement with the spindles 22. AConsequently when a gummed cap has been discharged from the machine at the point indicated at 43 in Fig. 9 and the empty spindle 22 moves opposite the cap 44 resting on the platform the recess 45 corresponding to the empty spindle 22 will receive the cap 44 and carry it forward out through the discharge end 46.0f

1' thechute 15 which is curved at this point.

As the cap 44 leaves the extremity 47 of the platform 39 the empty spindle 22 rises to engage and thereafter support and rotate thev loosely mounted on the table 27 within the' ring 37. The cam ring is provided at its lower edge with an inwardly extending flange 54 in which are holes which loosely receive the vertical guide pins 55 fixed in the table 27. The upper edge of the control ring 53 normally supports the cam ring 50 in operative position. When it is desired, however, to render the machine inoperative the control ring 53 is turned in a counter-clockwise direction and for this purpose it is provided with a handle 56 fixed on the outer end of a rod 57 which extends outwardly from the ring 53 through a slot in the fixed ring 37. Turning the ring 53 in a counter-clockwise direction brings the depressions 58 in the ring 53 opposite the pins 52 and thereupon the cam ring 50 falls by gravity below its operative posi tion. By turning the ring 53 in a clockwise direction the pins 52 of the cam ring 50 travel up the inclined surfaces 59 of the ring 53. When the ring 53 is turned in either direction the cam ring 50 is guided in its vertical movement by the pins 55.

During the gumming operation the spindles 22 travel on the upper active portion 60 of the cam ring 50. On the completion of the gummingoperation and during the'discharge of the gummed cap from the machine and until the empty spindle again rises to engage a cap it travels over the depressed inactive portion 61 of the cam ring. The rise 62 from the depression 61 to\the active part of the cam ring is located substantially opposite the discharge end of the chute 15. While each spindle is traveling over the depression 61 of. the cam ring 50 the head 49 of the spindle is received within a recess 63 formed within the upper surface of the flange 23 so that the top surface of the head .49 will be-substantially flush with the top surface of the flange 23. This construction permits the head 49 of each spindle to pass under the platform 39 of the chute, as best indicated in Fig. 4. As each spindle moves opposite the depression 61 ofthe cam ring 50 it is moved downwardly by means of a coiled expansion spring 64 encircling the lower end of its spindle and interposed between a plate 65 mounted on the spindle abovethe gear 35 and the under surface of the bushing 66 in the flange 24 in which the lower end of the spindle is 'journaled.

In order that the liquid gum or cement may be applied most conveniently to the under surface 20 of the flange 19 of the cap, the cap is supported in inverted position on the top of the spindle and thus the surface 20 is held and rotated on a. horizontal plane. Axs the spindle moves` upwardly with the inverted cap on its top end it pushes the flat central portion 68 of ther cap against the lower end of a valve control rod 69 slidingly received at its lower end 1n a 'guide 70 screwed into the under side of-acylindrical valve head or manifold 71 removably supported on the contracted upper `end 72 of the carriage 25. The head 71 is provided on its under side with a central boss 73 received within the upper end of an axial bore 74 formed in the carriage 25. In the lower end of the bore 74 is loosely received a cylindrical head portion of a bolt 76 the upper shank end 77 of which is threaded into the boss 73. In the bolt 76 is a transverse slot 78 which receives theinner end 79 of an eccentric key 80 havingy thereon. v The key 80`is then inserted in place and turned until a tight engagement is established between the part 79 thereof and the lower surface of the slot 78 in the olt 76.

The upper .end 82 of each valve control rod 69 is reduced and is guided in the upper end of a hollow adjustment nut 83 in which is received a coiled expansion springv 84 the upper end of which bears against theY top end of the nut 83 and the lower end of which bears against the shoulder 85 of the rod 69. When' a rod 69 is not raised by a cap covered spindle 22 the spring 84 holds the shoulder 85 against the upper end 86 'of the threaded portion-.of the guide 70. Each valve control' rod 69 is in axial alinement with one of the spindles 22. y In the upper end or head 49 of each spindle is a central recess 87 slightly larger in diameter than the lower end of each rod 69 so that in case a spindle rises without a cap on itthe valve control rod 69 over the spindle in question will not be raised and consequently the valve connected with it will not be operated. In order that a cap will rotate withthe spindle on which it is mounted in spite of the friction exerted against its upper surface by the lower end of a valve control rod 69 'the upper surface of the head 49 of each spindle is knurled or otherwise roughened to provide an eliicient driving contact between the upper surface of the head 49v and the cap resting on it.

Each rod 69 is positively connected by means of a plate 88 with the upper end of to y the valve stem 89 of a needle valve 90 adapted to seat against a valve seat 91 formed in a valve casing 92 provided with a threaded upper end 93 adaptedv to screw into a 'vertical hole or passageway 94 in the valve head 71 located adjacent the vertical bore 95 which receives the threaded ends of the guide and Fnut 83. The plate 88 is a'djustably held on the upper end 82 of the rod 69 between nuts in the valve casing 92 and with which communicates the inner end of a nozzle 102 threaded into the lower end of the valve casing 92 at an angle so as to direct the cement onto the flange 19 of the cap at the point where it joins with the body portion 18.

The liquid gum or cement is held in a tank located above the machine and consisting of a bottom 1015,. a cylindrical glass body part 106 and a top 107 in which is a` filling hole closed by the nut'108. The removable boltsV 109 hold the parts of the tank together. .Compressed air may he led into the top of the tank through the pipe 119 which has a swivel connection 119" with the tank top 107. The central part of the bottom of the tank is formed as a boss 110 threaded into the upper end of a valve-111 theflower` end of which is screwed onto the threaded central boss 112 of a plate 113 secured to the upper surface of the head 71.` The boss 112 is pro- 'vided with an opening 114 which leads into a central bore 115 in the top part of the head 71. Each vertical hole or bore 94 leading 'down into a valve casing 92 communicates.

withV thecentral bore 115i by a passageway 116. The outer extension 117 of each pas- 'my'l sageway 116 is closed by a "headless screw 118. lThese parts areall arranged so that they may be readily taken apart for cleaning. Inasmuch as the liquid gum or cement 120 in the tank is preferably put under pressure t0 assist in feedingl the cement to the caps, leakage of the cement upwardly past the valve stems 89 is prevented by means of a packing 121 interposed between the lower end of the threaded guide 122 in whichv the valve stem slides and a nut Upon the completion of the gumming ope eration the lower end of the spindle 22 car# rying the cap which has ust been gnmme'cl passes down the slope of the cam ring 50 and onto the depression 61, thereby lowering the head 49 into its recess 63% free of the cap to permit the latter to be discharged from the machine.v As the head 49 of the spindle sinks and frees itself from the cap the flange of the cap drops upon the recess of the shoulder 41 and also upon one of six recesses 126 of a disk-like plate 127 of the mechanism for discharging the gummed caps from the machine, as indicated at the point 43 by the cap 128in- Fig. 9'. The plate 127 is fixed upon the upper end of a vertically arranged shaft 129 journaled in the bearing 130 resting upon the table 27 0n the lower end of the shaft 129 is fixed a gear 131 which meshes with and is driven by a gear 132 of equal Size mounted on the lower end 29 of the carriage 25. Thus the plate 12.7 and the carriage 25 rotate synchronously, with the result that the recesses 126 of the plate 127 move oppositelthe recesses 42 ofthe carriage 25 to receive the caps which have just been gummed to convey them out of the machine. By the cooperative action of the recess 126 and the s recess 42 holding the cap which has just been gummed the cap is directed onto the ledge 134 of a plate 135 supported by the cross-piece 136 of the bracket 137 rising from the table 27 and on the upper end of which is supported the chute 15. The ledge 134 is formed on an arc with the shaft 129 as its center and supports the side of the gummed cap which had been supported in the recess 42. To prevent the caps being discharged from the machine from accidental vertical displacement a curved guard 1.39 is providedA under which the discharging cap passes. One end of the guard 139 is supported by the plate 135 and the other end is supported on a cross-piece 140 which serves to hold up and aline the

conveyor belts

16 and 17 at the point at which they approach the discharge mechanism. At the point at which the

conveyor belts

16 and 17 leave Vthe discharge mechanism they are supported by the cross-piece 141. The cross-pieces 140 and 141 may be supported in any convenient manner.

The cap discharging mechanism operates to discharge the gummed caps alternately upon the

belts

16 and 17. The parts which perform this operation comprise in addition to the plate 127 the arm 143 which pushes caps onto the belt 16 and the arm 144 which pushes caps onto the belt 17 The arm 143 is pivoted at 145 upon the plate 135. On its free end the arm 143 is provided with a downwardly extending pin 146 located over substantially the middle of 'the belt 16 and which serves to push each alternate cap onto the belt 16.4 A spring 147 connected at one end with the free end of the arm 143 and at its other end to a guide piece 148 supported on the cross-piece 140 serves to hold the pin 146 against the periphery of the plate 127 and to pull it into each alternate recess 126 in position to eject the cap therefrom. By referenceto Fig. 9 it will be seen that in the position of the parts as shown therein the pin 146 is held against the periphery of the plate 127 and that consequently when the next succeeding recess 126 moves opposite the pin 146 the latter will be pulled by the spring 147 into the recess and behind the cap therein. By the time this movement has been accomplished one of the pins 150 rising from the plate 127 will have moved'into contact with the cam surface 152 of the arm 143, thereby swinging the arm outwardly on its pivot against the action of the spring 147 andlcausing the pin 146 to push the cap onto the belt 16, as indicated in Fig. 11. When the pin 150 passes beyond the cam surface 152 of the arm 143 the spring 147 draws the arm 143 rearwardly and the pin 146 into contact with the edge of the plate 127.

lThe cam surface 152 of the arm 143 is of such length that while the pin 150 is traveling past it, thereby holding the pin 146 away from the plate 127, as indicated in Fig. 11, the cap 153 in the next succeeding recess 126 passes on the inner side of the pin 146 and is carried by the recess over onto the depressed portion 154 of a guide 155 placed between the

belts

16 and 17 and supported on the cross-piece 141. The cam surface 152 is of such length that the recess in which the cap 153 is located carries the cap onto'the guide 155 by the time the spring 147 is permitted to draw the pin 146 toward and into engagement with the plate 127.

The cap 153 is pushed out of its recess in the plate 127 and onto the belt 17 by means of a pin 157 extending downwardly toward the middle of the belt 17 from the free end of the arm 144 which is pivoted at 158 on the outer end 159 of the plate 135. The arm 144 is not directly actuated by one of the pins 150to push a cap onto the belt 17 but is actuated by a lever 160 pivoted at 161 on the end 159 of the plate 135. The inner end of the long end Aof the lever 160 is provided with a curved cam surface 163 with which the pins 150 contact in order to swing the arm 144 to push the caps out of the alternate recesses 126 in the plate 127 onto the belt 17. As a pin 150 moves into contact with the cam surface 163 of the lever 160 thereby turning it in a clockwise direction, viewing Figs. 9 and 11, the short end 164 of the lever 160 contacts with a lug 165 projecting, from the arm 144 near its pivot point 158, thereby swinging the arm 144 in a counter-clockwise direction to push a cap by means of the pin 157 onto the belt 17 1 By the time the recess carrying the cap 153 has brought it over the depression 154 of the guide 155 the lever 160 occupies the position shown in Fig. 9 with a pin 150 in the depression 167 at the base of the cam surface 163. This position of the parts permits the spring 168 connecting the longend of the lever 160 and the free end of the arm 144 to free the short end of the lever 160 from the lug 165 of the arm 144 and draw the pin 157 into the recess 126 carrying the cap 153. As the plate 127 .continues to rotate,.permitting the pin to enterV fully into the"'rec'ess and get Vbehind the cap 153, the next succeeding pin 150 moves into contact with the cam surfacev 163, thereby swinging the lever 160 in a clockwise direction and bringing the short end 164 thereof against the lug 165 of the arm 144. The pressure of the short arm 164 of the lever 160 against the am 144swings 'the latter in a counterclockwise direction with the result that the pin 157 pushes the cap 153 ut of itsV recess and onto the belt 17 The long'end of the lever 160 vis provided on its inner side with a curved'v surface 169 to prevent the spring y weight o The caps are prevented from entering the machine for the gumming operation until all the parts of the machine are in proper condition by means of a stop finger 171 fixed on a pin 172 pivotally mounted on the under side of the lower end of the chute 15 and carrying on its'outer end a handle 173 by which the stop finger 171 may be turned manually. The finger 171 is located in a slot 174 cut' in the middle of the lower end of the bottom of the chute 15 so that when the finger is turned to the position shown in Fig. 4 it will engage with the rear side of the dish-shaped portion of the lowermost can cap at about its middle point. By turning thehandle 173 toward the carriage 25 the stop finger 171 is broughtinto a horizontal position below the upper surface of the platform 39, as

shown in Fig. 2, thereby permitting the caps to descend from the chute onto the platform 39 in position to be picked upand carried' around by the heads 49 of the spindles 22.

The operation of the improved cap gumming machine is as follows :-The carriage 257 the spindles 22 and the plate 127 all rotate continuously. During the rotation of the carriage 25 the lower ends of the spindles 22'travel over the upper surface of the cam ring 50. While the lower ends of the spindles 22 are in the depression 61 of the cam ringxthe heads 49 of the spindles are received within the recesses 63 in the annular flange 23 of the carriage; and on the other hand, while the lower ends of the spindles 22 are on the raised portion of the cam ring the heads 49 of the spindles are lifted above the recesses 63. If no caps are on the heads 49 of the spindles the lower ends of the rods 69 are .received in the recesses 87 ,of the heads 49 and the valves 90 are not opened.

Assuming that all the parts of the machine are in readiness for the gumming operation the handle 173 attached to the stop finger 171 is turned to bring the stopfinger into its horizontal lposition to permit the can caps to slide down the chute 15 and onto the platform 39. As a recess 42 formed in the shoulder 41v of the carriage 25 moves opposite the can cap resting upside down on the platform 39 the the succeeding caps in the chute pushes the cap on the platform 39 into the recess 42`s0 that-it is carried forward out through the curved discharge end 46 of the of the platform the lower end of the spindle corresponding to the recess 42 in which the cap is located travels up the incline 62 of the cam ring 50,-thereby causing thevhead 49 of the spindle to enter the dish-shaped portion 'of the cap to support and rotate the cap for the gummmg operation. Further rise of the spindle `with the cap on the upper end thereof with the rod 69 is lifted from its seat, thereby permitting the liquid gum or cement to be discharged onto the rotating upper surface 20 of the iange 19. This action continues until the spindle carrying the cap arri-ves at the slope 125 of the cam ring 50, by which time the fiange ofthe cap is properly coated. As the lower end of thespindle travels down the slope 125 the gummed cap first sinks out of contact with thelower end of the rod L69, thereby permitting the spring 84 to restore the parts controlled by it to normal position and close the valve against its seat. By the time the lower end of the spindle has reached the bottom of the slope 125 the head 49 of the spindle has sunk into its recess 63, permitting the flange of the gummed cap torest at one side upon the' recess 42 and to rest at its other side upon' a recess 126 of the plate 127 which has moved opposite the recess 42 in which the gummed Vcap is carried. The spindle is now free of the gummed cap and as the carriage 25 and the plate 127vcontinue to rotate'in opposite directions the gummed cap is pushed onto the curved ledge 134 of the plate 135. The spin-` Fig. 9 with the pin 146 of the arm 143 held against the periphery of the plate 127 by the spring 147, the pin 146 will enter the recess 126 carrying the cap which has just been gummed and assume a position behind the cap so that when the next succeeding pin 150 encounters the cam surface 152 of the arm 143 the latter will be swung to ejectthe cap from the recess and deposit it 'upon the belt 16.

The arm 143 will be held in its outermost pol sition by reason of the contact between the pin 150 and the cam surface 152 until the next -succeeding recess 126 with a gummed cap therein passes beyond the pin 146 and over the depression 154 of the guide piece 155. The arm 143 will then be restored to the position shown in Fig. 9. As the plate 127 continues to rotate the pin 150 in contact with the` lever 160 leaves it and the pin 150 approaching the long end of the lever 160 is received in therecess 167, thereby permitting the spring 168 to swing the lever to free the short end 164 thereof from the lug 165 of the arm 144 andpull the latter inwardly toward the plate 127 to enter the pin 157 into the recess carrying the gummed cap. By the time therpin 157 is fully in the recess and behind the cap the pin 150 encounters the cam surface 163, thereby turning the-lever 160 and bringing the short end 164 thereof into contact with the lug 165 to Vswing the arm 144 and cause the pin 157. to push the cap onto the belt 17.A .y
