Fig. '7 is a plan view taken on a line l-l of Fig. 6.

Fig. 8 is a section taken through 3-8 of Fig. 1.

Fig. 9 is taken on a line 9-9 of Fig. 10 and shows the manner the cans A are delivered to the bail placing machine. Fig. 10 is a detail of the can stopping mechanism. Fig. 11 is a top plan view of the machine taken on a line |||l of Fig. 9. Fig. 12 is a detail view of the can stopping device showing its position at the time of said cam release.

Referring to Fig. 1, the numerals designated as Ill and II are the side frames which support the mechanism I2 of the bail placing machine; said frames also serve to secure said machine to the body I3 of the can filling machine through the medium of screws H.

The casting I5 is secured to extension ears Hi and ll of the side frames l0 and II, said frames protruding above the surfaces i8 and IQ of the casting I0 and II. The casting l5 serves to support a bail basket 20.

A number of balls 2| is placed inside the bail basket 20 by the operator of the machine. The wire bails 2| due to their gravity drop upon a casting 22. The casting 22 is provided with a shelf 23 which is sunk into the casting 22 so that when one of the balls 2| drops upon said shelving, said bail will not protrude above the top surface of the casting 22. The casting 22 is secured to a pair of leg shaped members 24 and 25, said members being secured to said casting by means of screws 26.

A further pair of leg shaped members 21 and 28 are reversibly secured to the surfaces l8 and I9 of the side frames l0 and II by means of screws 29.

In this manner the casting 22 is enabled to slide reciprocally through the medium of the leg shaped members 24 between the surfaces l8 and I9 and the reversibly mounted leg shaped members 21 and 28.

A shaft 30 is held by means of bearings 3|, said bearings extending from a casting 32. A worm gear 33 is pinned on said shaft 3|. A worm 34 is secured to a shaft 35 which rotates in a bearing 36 of the casting 32. A toothed clutch 31 is slidably mounted at the opposite end of the shaft 35.

A similar toothed clutch 38 that is secured to a pulley belt 39 rotates freely upon the shaft 35.

When the gear clutch 31 is connected to the gear clutch 38, the worm 34 which is secured to the shaft 35 rotates the worm gear 33. A bevel gear 40 which is in engagement with the bevel gear 4|, turns a square shaped shaft 42. The bevel gear 4| is held in place by means of the bearing 43, said bearing being also held by means of the shaft 35, said shaft projecting through the bearing 44. The square shaped shaft 42 is placed into asquare opening 45 of the member 46. said member 48 being secured to a flexible coupling 47 which in turn is secured to a shaft 48. Said draft 48 is secured to a disc hub 49. The disc hub 49 (see Fig. 4) has a tooth shaped member 50 secured to it. A similar tooth shaped member 5| is secured to an L-shaped bracket 52. One leg 53 of the bracket 52" is secured to a slidably mounted member 54. The opposite leg 55 of the bracket 52 is pivoted to a hinging arm 53 that hinges at the point designated as 51. The hinging arm 56 is secured to a slidably mounted member 58.

A set of pins 59 and 60 are secured to both members 54 and 58. When the wire bail 2|, (see Fig. 4), drops out of the bail basket 20 on the 4 the casting i5. Said plates are shafts l0 and locate themselves in the space between pins 59 .and of the slidably mounted members 54 and A pair of pins BI and 62 serve to hold the bracket 52 below the casting 22 in such a manner that the bracket 52 can be slid due to the pins Bi and 82 being located in slots 62 of the bracket 62.

The casting 22 is provided with a pair of ears 84 and 85. A pair of oscillating arms 68 and 61, is hinged at one end on a shaft l8, and the opposite ends of said arm are secured to the ears 84 and 85 of the casting 22.

A section 89 of the oscillating arms 86 and 01 has a slot 10. A pin II is placed into said slot 10 and is secured to a rotating disc 12 on one side of the machine and to a disc 12 on the opposite side of said machine. The discs 12 and 12' are secured to the shaft Ill and rotate with it.

A pair of hinged plates 12 and means of the pin 15, said pin being secured to forced into the position shown in dotted lines illustrated in Fig. 4 by means of spring II. the latter being secured to said casting I! by means of the screw 11.

A pair of pins 18 are secured to the casting 22, said pins serve to open the plates 12 and 14 and then into the position shown in Fig. 4 when the casting 22 returns from its position shown in broken lines. A spring 12 serves to hold the bracket 52 in the position shown in Fig. 4.

Referring to the modification shown in Fig. 6, the mechanism l2 for placing the bails to the cans is similar to the arrangement described in Fig. 1.

In this particular case, instead of using two oscillating arms 86 and 61 as shown in Figs. 1 and 2, there are provided a pair of sliding shafts 80 and 80'. The shaft ll slides into the bearing 8| of the casting 82 and a bearing 83 of the casting 84. of the casting 82, and into a bearing 82 of the casting 84. A pair of discs 24'' and II similar to that of discs 12 and 12 which are incorporatedin the machine shown in Figs. 1 and 2 are also used in the machine shown in Fig. 6. The mechanism for driving discs-l4' and I! is similarto that of the mechanism described in Figs. 1 2; in this particular case, however, the worm gear 24 is rotated by the shaft 25. said shaft being rotated in a casting 88.

A pair of castings B1 and 88 are secured to the 80". The castings l1 and 28 are provided with slots 89. A pair of pins 20 are slidably mounted in slots 89. Said pins are also rigidly secured to the discs 84* and 85. The end section SI of the shafts 80 and 80' are secured to the casting 22 by means of the ears 92. The casting IS in this instance is held in place by the protruding members 22 of the casting Ii.

Referring to Fig. 1, the can A is delivered to the bail placing machine on the track B and is rolled along by means of the belt 0, said belt being moved by means of the rollers D in the direction shown by the arrow in Fig. 3.

A stopping bar E is provided on the can filling machine It to arrest the movement of said can when said can shall have arrived exactly at the position as shown in Fig. 3, the aforesaid position of said can being necessary to enable the bail 2| to be affixed upon said can.

In Fig. 6, the can A is delivered to the bail placing machine in an upright position through the medium of the conveyor belt F. In this in- 14 are hinged by i The shaft 80' slides into a bearing 8| 2,154,071 shelf 23 the ends 2i and 2| of said wire bail stance the can is held in the necessary precise position for placing said bails upon said cans by means of an arm H which is operated by the can filling machine II.

The stopping arms E and H are required to be operated in such a manner that when the mechanism l2 of either machines returns for the next following wire bail, said stopping arm is cleared out of the path of the can A in order that a new can may be brought forward. Immediately after the can A leaves the machine, the stopping arms E and H are brought into position and in readiness to hold the can in place and for the placing of the next oncoming bail. The clutches 31 and 38 are brought into operation in conjunction with the stopping arms E and H so that when there is no can on the machine the clutch 31 remains disconnected from the clutch 38.

Referring to Fig. 9. when a can A is delivered to the bail placing machine said can stops against the stop E. The ear of the can depresses the stop I: which in turn operates the moving arm K thereby causing the operation of the clutch 31, 22 shown in Fig. 1.

When the bail placing machine returns to receive another ball the cam B pushes the stop E to its downward limit thus releasing the can upon which the bail has become afiixed, and also from rolling further, said stopping arm placing itself directly in the path of the can. Since the conveyor belt is in continuous operation in the direction shown in Fig. 3, the can A, although prevented from rolling, continues to turn on its circumference until the ear G of said can A stops against the stop E. Due to the movement of the aforesaid belt 0, the ear G of the can A is forced against the stop arm E and presses against said stop arm toward'said arm in the direction as shown, the movement aforesaid automatically operating an arm K, said arm connecting the toothed clutch 21 to the toothed clutch 22. The leather bet I0 is continuously rotating and is driven by the motor of the filling machine it comes activated in the following manner: The

worm 24 turns on the worm gear 23, said gear being secured to the shaft 35 and operates the oscillating arms I and '1 through the medium of the discs I2 and 12'. The arms I! and 41 cause the casting 22 to slide reciprocally as shown in Fig. 4. During the aforesaid operation, the bevel gear 42 engages the bevel gear 4| which in turn operates the square shaped shaft 42, said shaft 42 .belng slidably mounted on the flexible coupling 41 and which turns the disc 42. The toothed shaped member I. that is secured to the disc 49 rotates with said disc.

The tooth shaped member ll being secured on the slidably mounted L-shaped bracket 42 is placed into the path of the rotating member ll. As soon as said bracket I2 contacts with members II, said member Si is carried along thus compelling the L-shaped member to move in the direction shown leg I! of the forced the slidably mounted member 84 so as to be moved into the position shown by the arrow. The slidablg mounted member 58 also moves into the position shown by the arrow, due to the hinging movement of the arm 58..

The movement of both the casting 22, moving forward in the direction shown by the arrow, and the movement of the slidably mounted members 54 and 58 are timed in such a manner that when the casting 22 arrives at the position shown by the broken line in Fig. 4, the contact between the tooth shaped members," and is completed. The operation aforesaid is due to the rotation of the member 58 at the time the end sections 2| and 2i of the wire ball 2! are free to locate themselves into the respective openings of the ears G of the can A. After the completion of the operation aforesaid the casting 22 returns to its original position as shown in Fig. 4. During the period of the operation of said machine, the hinzing arms 13 and 14 are brought to the position shown by the broken lines due to the force of the spring I6. This latter operation tend to support the balance of the stored wire bails 21, said bails being held in the basket 28 and are prevented from dropping out therefrom when the casting 22 shall have completed the return to its original position, and at which time the pins 18 open the hinging arms I8 and 14 thus allowing a new wire bail to drop upon the shelf 23 in readiness for the next delivery to the can A. a

The operation of the machine shown in Figs. Sand '7 is similar to the manner of operation with reference to the description of Figs. 1 and 2. Instead, however, of employing oscillating arms 66 and 61 the shafts 88 and cause the movement of the casting 22 due to the pins 88 which rotate with the discs 84 and 85, said pins sliding into the slot 88 of the casting 81. The aforesaid movement of the pin causes the shafts 88 and 88' to slide into the bearings 8| and 8!", and 88 and 83" and which cause the reciprocal movement of the casting 22.
