TURNER, 0F LOS ANGELES, CALIFORNIA, ASSIGNOR OF ONE-HALF TO FORD YV. HARRIS, OF' LOS ANGELES, CALIFORNIA VESSEL CAPPING MACHINE Application filed March 30, 1927. Serial No. 179,605.

It is a still further object of my invention to provide a vessel capping machine in which the cap feeder and means for connecting same with the plunger constitute a single member.

The sliding feeder also necessarily extends a considerable distance to one side of the vertical axis of the capping plunger upon which the ca-pper body slides. This greatly increases the friction att-ending the sliding relation between the plunger and the body and causes rapid wearing of the slide ways.

It is a. further object of my invention to provide a capping machine in which the parts are conipactly disposed close to lthe vertical axis of the capping plunger.

In order to achieve the above noted objects I have provided a rotatable feeder which carries caps from the magazine into the path of the capping plunger.

lt is highly desirable and hence an object of my invention to provide a vessel capping machine in which a rotatable feeder is connected to the capping plunger in such a manner that the feeder will be rotated while the plunger is in the upper part of its path and will beheld against rotation when the plunger is in the lower part of its path.

Hitherto the work of actuating the feeder inits feeding movement was done entirely by relative movement of the plunger and the capper body during the upstroke of the plunger. This required said relative movement to be fairly long.

. It is an object of iny invention to shorten said relative movement by utilizing a portion of the down stroke of said plunger in operating said feeder in a feeding movement.

Further objectsV and advantages will be made manifest in the following description and in the accompanying drawings in which,

Fig. l is a prespective view of a preferred embodiment of the capping machine of my invention with the capping plunger in its upward position relative tothe body of the machine.

Fig. 2 is a horizontal sectional view taken My invention relates to vessel capping machines and more particularly to a machine adapted to apply flexible caps to milk bottles and the like.

In the bottle capping machines in general use, a capping plunger is reciprocated vertically over a given path. A cap magazine is mounted on a body which is slidably urged downward on the plunger by gravity. The

'e downward movement of this body with the plunger is stopped by the body engaging a bottle placed in the path of the plunger for capping. A sliding cap feeding mechanism is mounted on the capper body and as the "f5 plunger continues downward to cap the bottle, the cap feeder is retracted into a position of readiness. rlhen as the plunger returns upward the cap feeding mechanism operates to feed cap into a path of the plunger, this cap being retained in said path by a restricted mouth formed on said body in the plunger path.

This sliding cap feeder requires consider- U able power for its operation and therefore the capper body must be made quite heavy in order to ensure that the feeder will function. The cappcr body comes in forcible contact with the bottle and excessive weight in the body results in chipping glass from the heb mouth of the bottle. rl`his injures the bottle andz adulterates the cont-ents thereof and is therefore very undesirable.Y

The primary-object of my invention is to provide machine which will include auto- 'f--S matic means for capping milk bottles in contra-distinction to the usual hand operated devices new employed.

Another obj ect of my invention is to provide a vessel capping machine in which the cap feeder is operated by a comparatively small amount of power. f

The above-mentioned sliding cap feeder reci rocates with a rapid motion and ren quires considerable linkage for its operation.

il rlhe pivots of these links quickly become worn and the consequent play makes the operation of the sliding` feeder very noisy. V L ,A v n' 1 It is another object to provide a resseL capping machine m which the cap feeder operates without the use of linkage.

The capping machine 2O is mounted upon a` capping` machine reciprocator 21 which is reciprocated vertically over a fixed path by a. suitable power mechanism, not shown. As the reciprocator 21 moves up and down, the capping machine 2O is adapted to move with the reciprocator and does not function unless a bottle 22 is placed in the proper position therebeneath. Vhen a bottle 22 is properly )laced beneath the capping machine, the machine moves into Contact with a bead 23 surrounding the mouth of the bottle and applies a cap 24 by inserting it in the mouth of the bottle. The capping machine 20 may be described as follows:

A slide frame 30 has a` vertical plate 31 which is secured to the reciprocator 21 as by cap screws 32. Formed at the upper end of the plate 31 is a projection 33 which has a suitable vertical aperture 34. Extending from the lower end of the plate 31 is a guideyoke 36 which provides opposed arms 37 and 38 in which guideways 39 and 40 are formed which are diametrically opposed to each other upon opposite sides of the vertical axis of the aperture 34. A capping plunger 44, as shown in Figs. 1 and 3, includes a square plunger body 45 having polished side faces, from which body a cylindrical neck 47 extends downward and receives at its lower end a capping plunger head 48. A plunger spring stem 52 extends upward from the square body in axial alignment with the body 45 and the neck 47. rlhe stem 52 has a pin hole 53 at its upper end and is adapted to receive a compression spring 55. The upper end of the stem 52 is inserted upward through the hole 34 so as to compress the spring 55, and a suitable pin 56 is then inserted in the hole 53 to retain the stem 52 against withdrawal from the hole 34.

The square body 45 has a: recess 60 formed in the inner side of t-he lower end thereof and which is adapted to receive a stop block 61. The square plunger body 45 and the stop block 61 are provided with aligned openings 63 and 64. The hole 64 is threaded so as to threadedly receive a cam-follower screw 65 which is adapted to pass freely through the hole 63 without engagement with the walls thereof. The cam-follower screw 65 is slotted at 66 for manipulation by a screw driver, and has a cam-follower pin 67 provided upon its opposite end eccentric with the axis of the screw, as clearly shown in Fig. 3. The screw 65 is adapted to be inserted through the hole 63 and screwed in the hole 64 until the cam-follower pin pro-jects beyond the inner surface of the stop block 6l, as shown in Fig. 4. A nut 68 is then adapted to be screwed upon the outer end of the screw 65 and tightened against the outer face of the square plunger body 45. TWhen the nut 68 is thus tightened to secure the screw in place, the cam-follower pin 67 may be disposed at an adjustable position relative to the vertical medial plane of the machine upon which the sectional view shown in Fig. 4 is taken. The purpose of this adjustment will be described later.

The capping machine 2O has a body 70 which includes a main casting 71 and a base member 72 which are associated in a manner to be described later. The casting 71 is best illustrated in Figs. 1, 2 and 3 and includes an upper floor 75, an intermediate floor 76, and a lower floor 77. These floors 90 are connected at their side portions by main slide bars 79 and 8O which accurately lit the diametrically opposed guideways 39 and 40. At the opposite end of the upper floor 75 from the connection of this iioor with the slide bars 79 and 80, a cap magazine receptacle 82 is formed which is substantially cylindrical in shape and has a cylindrical cavity 83 in which a tubular paper magazine 84 of bottle caps 24 is adapted to lit. rlhe cylindri- 100 cal cavity 83 extends downward to a magazine tube seat 85 from which a cap conveying bore 86 extends downward and inward into communication with the lower face of the lower floor 77 A peek slot 87 is formed in 105 the wall of the receptacle 82 while a peek hole 88 is provided in thc wall of the bore 86. These peek holes are for the purpose of obtaining information as to the number of caps remaining in the machine.

rl'he intermediate floor 76 is formed integrally at one end with the magazine receptacle 82 and the other end isconnected with the lower floor 77 by a plunger head cylinder 90. The cylinder 90 has a bore 91 of sufficient- 115- diameter that the plunger head 48 may reciprocate vertically therein, the bore 91 terminating at the lower surface of the intermediate iioor 76 and opening downward through the lower floor 77. A hole 90a is formed in 120 the cylinder 90 through which to observe the action of the plunger head 48 in the bore 91. The bore 91 is disposed on the aXis of the capping plunger 44 and a hole 92 in the intermediate floor 76 is adapted to slidably 125 receive the plunger neck 47 so that the neel; 47 may actuate the plunger head 48 in the cylinder bore 91. A plunger guide recess 95 is formed in the opposite end of the upper floor 75 from where this connects with 18C by screws 128 in a manner VThe upper the magazine receptacle 82, the recess 95 slidably fitting three side faces of the square plunger body 45.

A guide block 96 is secured by screws to this end of the upper floor so as to slidably engage a fourth side face of the square plunger body 4:5. rlhe square plunger body thus slidably engages the upper floor 75 but is prevented from rotation relative to the body 70.

The casting 71 is solid between the cylinder 90 and the cap conveying bore 86 and a cam roller stem bore 115 is formed in the casting to extend between the upper face of the intermediate floor 76 and the lower face of the lower floor 77 substantially parallel with the axis of the capping plunger 14.

end of the bore 115 has an enlarged counterbore 116. The upper floor 75 has a bore 117 axially aligned with and substantially of the same size as the counterbore 116 and which extends entirely through the upper floor 75.

A cam rotor 120 has a substantially cylindrical cam body 121 and a rotor stem 122 extending axially from therlower end of the body and a pin 123 extending axially from the up ier end thereof. The rotor body 121 is of slightly less diameter than the opening 117 in the upper floor 75 and when the rotor 120 is inserted downward through the opening 117, the stem 122 is journalled in the bore 115. Before the rotor is thus inserted into the opening 117 an anti-friction thrust bearing 125 is placed in the counterbore 116 and when the cam rotor is in place it is supported upon this bearing. An anti-friction bearing 126 is adapted to fit the pin 123 of the rotor 120 and be disposed in the upper portion of the opening 117, as clearly shown in Fig. 3. A bearing cap 127 is adapted to be secured against the upper face of the upper floor 75 to position the upper bearing 126 so that the rotor 120 is accurately held against axial movement relative to the capping machine body 70. Cam grooves 130 are provided in the outer surface of the cam roller 12() and are of such width as to receive the cam-follower pin 67 as shown in Fig. 3. rlChese grooves provide cam surfaces, the function of which will be described later.

The lower end 131 of the rotor stem 122 where this projects below the lower floor 77 is polygonal in cross-section, this in the present instance being triangular.

rlhe lower floor 77 is provided. with dowel pin holes 152 and 153 on the medial vertical sectional plane of the view shown in Fig. 3 near the ends of the lower floor. @n opposite sides of theV dowel pin hole 152 are formed threaded holes 155. On each side of the dowel pin hole 153 is formed bores 156.

The base member 72 is of substantially the same length as the lower floor 77 and has lower walls 159 and 160 extending upward from its opposite ends. The walls 159 and 160 are Vof the same height and dowel pins 161 and 162 are centrally provided to project upward from these walls so as to be received in the dowel pin holes 152 and 153 respectively in order to accurately position the base member 72 relative to the body casting 71. Counterbored holes 165 are formed in the base member 72 so as to be aligned with the holes 155 of the lower floor 77 and screws 166 are adapted to be extended upward in the holes 165 and screw into the threaded holes 155 so that the heads of the screws 166 are received into the counterbored portions of the holes 165, as clearly shown in Fig. 8.

Threaded holes 167 are adapted to be formed in the base member 72 on opposite sides of the dowel pin 162 so as to be aligned with the holes 156 formed in the lower floor 7 7 Cap screws 172 are adapted to pass into the holes 156 and are threadedly received into the holes 167, as clearly shown in Fig. 9.

W hen the base member 72 is thus secured in place pon the body casting 71, a finger hole 175 which is formed in the base member 72 is disposed axially beneath the lower mouth of the bore 86. A cylindrical recess 176 is formed in the upper face ofthe base member 72 in axial alignment with the cam rotor 120. A cylindrical plunger mouth 177 extends vertically through the ba se member 72 in axial alignment with theA plunger 44. The lower portion of this -mouth 177 is counterbored to form a frusto-conical bottleguiding mouth 178.

When the base member 72 is assembled upon the lower floor 77 the lower floor 77 and the upper face of the base member 72 are parallel and form a flat space 212 in which a rotary feeder 213 is disposed. The rotary feeder l213 is in the form of a disc which has a central polygonal opening 2141 which fits the polygonal end 131 of the rotor stem 132. The feeder 213 is then held in place upon theV lower end of the rotor stem 122 by a washer 215 and a screw 216 which extends upward through the washer and is screwed into a threaded hole 217 provided centrally inthe lower end 131 of the stem 122. The recess 176 in the upper face of the base member 72 provides a space in which the washer 215 is disposed when the machine is assembled. The rotary feeder 213 when thus mounted upon the lower endof the rot-or stem 122 has opposite portions thereof disposed adjacent to the lower end of the cap bore 86 and to the plunger head bore 91 respectively. rlhe upper face of the feeder 213 makes a sliding fit with the lower face of the lower floor 77.

A series of holes 220 are formed vertically through the feeder disc 213, these being uniformly slightly less in diameter than the diameter of the caps 24 and are symmetrically arranged about the center' of the feeder 213. In the present instance, there are three of the holes 220. Counterbores 221 are formed in the upper end of the holes 220 having the same diameter and the same depth as one of the caps 24. The holes 220 are formed at such a distance from the axis of the feeder 213 that each is successively disposed in alignment with the cap bore 86 and the plunger bore 91. As each of these holes comes opposite the cap-conveying bore 86, a cap drops downward into the counterbore 221 thereof and upon rotation of the feeder is carried through an angle of 180 into alignment with the plunger bore 91.

The operation of my machine is as follows:

As before stated the capping function of the machine does not take place unless a bottle 22 is suitably positioned therebeneath as the machine descends downward with the vertical reciprocating movement of the machine reciprocator 21. The body 70 of the machine is vertically slidable relative to the slide-frame 30 and the capping plunger 44, between the downward position of the body, where it is shown in Figs. 1 and 6 and the upward position of the body which is shown in Fig. 3. The body 70 remains in its downward position excepting when the bottle 22 is so placed that the annular bead 23 thereof engages the bottle-guiding mouth 178 and stops the bodys downward movement. lhen this occurs the plunger 44 continues downward under the yieldable pressure of the spring 55. This relative movement between the plunger and the rotor 120, mounted against axial displacement on the body 70, opera-tes the rotary feeder 213 in the following manner:

WVhen the capper body is in its lower position, the cam-follower pin 67 has the position 250 shown in full lines in Fig. 4. At this time one of the holes 220 in the rotary feeder 213 is opposite the cap bore 86 and has here received a cap in its counterbore. Another of the holes 220 is empty and is disposed so that a 120 rotation of the feeder in the direction of arrow 240 will bring that hole into alignment with the cap-conveying bore 86. The third hole 220 carries a cap in its counterbore and is disposed so that a. rotation of the feeder in the direction of the arrow 240 will bring the third hole into alignment with the plunger head bore 91.

The cam grooves 130, as shown in development in Fig. 4, constitute a. single-cycle cam multiplied three times. In each cycle the cam-follower pin 67 is adapted to move from the position 250 downward to the position 251 and return to a position 252, which cor-v responds to the position 250 for the next succeeding cycle. Considering the cycle to commence with the Contact of the bottle-guiding mouth 178 with the bottle 22 and the consequent beginning of a downward movement by the plunger 44, relative to the body 70, the cam-follower pin 67 here leaves the position 250 and contacts a cam slot surface 253 which causes the cam rotor 120 to rotate until the follower pin 67 has reached the position 254 where it is disposed between the walls of a cam slot 255 which is in vertical parallelism with the axis of the rotor 120. In moving from the position 250 to the position 254, the cam-follower pin 67 has caused the feeder to rotate 60. This brings the third mentioned of the openings 220, charged with a cap, into alignment with the plungerhead bore 91. As the plunger continues downward after the cam-follower pin 67 has reached the position 254, the feeder 213 is held in position so that the plunger head 48 will enga-ge the cap 24 disposed in its path and will pass through the hole 220 in which this cap rests to the position in which it is shown in Fig. 6, where the plunger forces the cap 24 into the mouth of the bottle l22. Bottles 22 are so positioned vertically that the plunger 44 arrives at capping position when the machine reciprocator 21 reaches the lower end of its downward movement. The eXtreme downward position of the plunger head 48 relative to the body 7 0 is determined by contact of the stop block 61 against the upper surface of the intermediate floor 76. As the reciprocator 21 returns upward the plunger 44 is raised from the position in which it is shown in Fig. 6 and the camfollower pin 67 rises from the position 251 to the position 258 in which it engages the cam surface 259. During the fina-l upward portion of the movement of the plunger 44 relative to the body 7 0, the cam-follower pin 67 moves from the position 258 to the position 252. This movement of the cam-follower pin 67 causes another 60 rotation of the rotor 120 and the rotor feeder 213. This 60 rotation added to the 60 rotation which toolr place on the downward stroke of the plunger 44 brings the empty hole 220, first referred to as such above. into alignment with the cap bore 86 so that this hole receives a cap. As before mentioned. the cam surfaces 253 and 259 and the cam slot 255 are triplocated about the surfaces of the rotor 120 so that for each downward and upward movement of the plunger 44 the rotary 'feeder 213 is rotated 120J in the direction of the arrow 240 and a cap is fed into the path of the plunger head 48 in the manner above described.

An adjustment of the screw changing the position of the cam-follower pin projecting eccentrically therefrom, causes a. change in the position of the rotary feeder 213 for a given vertical relation between the plunger 45 and the machine body 70. This adjustment makes it possible to determine accurately that the feeder 213 will be so rotated by engagement of the cam rotor 120 by the follower-pin 67 that a hole 220 will be in correct axial alignment with the plunger head 48 during the lower portions of its downward and upward movements.
