ozone KIRKEGAARD, OF NEW YORK, N. Y., ASSIGNOR TO IMPERIAL STOPPER COMPANY, A CORPORATION OF MAINE.

AUTOMATIC-FEED CAPPING-MACHINE.

Specification of Letters Patent.

Patented Nov. 24, 1908.

To all whom it may concern:

Be it known that I, Gnono Kmnnoaann, a

citizen of the United States, and a resident of the city of New York, in the county of New York and State of New York, United States of America, have invented certain new and useful Improvements in Automatic- Feed Cappin hlachines of 'which 'the following is a specification.

ping machine made according to my invention. Fig. 2 isa perspective view of a bottle stopper or cap which I have invented and in conjunction with which the present invention may be used to advant-a c. Fig. 3 is a side elevation of a portion 0 my improved apparatus showing a part of the automatic feed mechanism which I have invented.

Fig. -i-is a plan view of the automatic feed mechanism. Fig. 5 is a front elevation of a portion of my machine showing a pair of collars and cams which I use to actuate a feed arm. Fig 6 is a sectional side elevation of the feed mechanism. This view is similar to that shown in Fig. 3, but in this case the parts are shown in different relative positions. Fig. 7 is a plan view of the parts shown in Fig. 6, the section being taken through the line 7''( in Fig. 6.

Like characters of reference designate corresponding parts in all of the figures.

10 designates a standard or frame upon which the various parts of my apparatus are mounted. This frame comprises a base 11 in which a treadle 12 is pivoted at 13. A tension spring 14 is attached to the frame and to this treadle to raise and to normally maintain the treadle and its connected parts in their raised position.

15 designates a vertically slidable rod which is supported by the frame 10 at 16 and also by the bracket 17 which is rigidly attached to the frame. The rod 15 is connected with the treadle 12 by means of a pitman 18. A collar 15 is attached to the rod;

15 near its .upper end.

19 and 20 designate two arms which extend horizontally from the frame 10 and which may be constructed, as shown, to be integralparts thereof. These two extending arms are arranged to slidably support a reciprocating shaft 21v which is associated with the rod 15 by means of a yoke 22 which fits loosely over the latter. The shaft 21 isaflixed to the outer end of the yoke 22 at 23 and is normally maintained in a raised position by means of a compression spring 24 which surrounds the rod 15 and is placed between the lower portion of the yoke and the upper portion of the frame 10. The lower end of the shaft 21 is provided with a flange 25 which limits the upward movement of the shaft by striking against the outer end of the extending arm 20. The outer edge of this flange 25 is threaded and a collar 26 is attached thereto. This collar is provided at its lower end with an inwardlv projecting lip 27 l 30 esignates a forming rin or die which is provided with internal surfaces 31 which are arranged to engage with ortions of a bottle stopper or ,cap. This orming ring may be made up of a plurality of sectors held together and in horizontal alinement by means of

springs

32, 32 which are set into grooves in the external surfaces of the sectors. This forming ring is preferably of a vertical length somewhat less than the distance between the bottom of the flange 25 and the top of the projecting lip 27. As it is held in place between these parts it is therefore loosely held thereby, and a'pin 33in one of its sectors and extending intoa hole in the flange 25 may be provided to hold the forming ring from rotation.

The lower part of the shaft 21 is bored out' I for the reception of a secondary or compression shaft 34 which is vertically movable within the shaft 21 and extends down through the forming rin 30. A pin 35 fixed in the compression shaft 3 passes through the vertical slots 21 in the sides of the shaft 21 and limits the downward movement of the compression shaft 34 within the shaft 21. The compression spring 36 is placed within the hollow portion of the shaft 21 above the compression shaft 34 to press the latter outward. The compression shaft 34: may be magnetized or a permanent ma et 37 may be inserted within its lower end 4.0 is a bracket permanently afiixed to the frame 10 and extending aroundthe rod .15

7 to a point directly in front of the latter,

where, at 41, it pivotally supports the inner member 42 of a swinging feed arm thus providing means for the latter to move horizontally. The member 42 is rigidly attached to the pivot 41 as is also an actuating lever 43 which carries at its outer end an antifriction roller'44. The outer member 45 of the feed arm is pivoted at 46 to its inner member 42. The outer end of this arm 45 forms a cap-earrying head 47 which may be cut out as is shown at 47 for the rece tion of certain parts of the cap. A cam ever 48 extends downward from the rear portion of the arm 45, and a stop lug 49 for limiting the downward position of the arm 45 may be made integral therewith and arranged to engage with the underside of the inner member 42; A spring 46 may be provided and arranged to press the cap-carrying head downward.

A collar 50 is affixed to the rod 15 at a point opposite the bracket 40 and this collar is provided with a projecting cam surface 51 which is arranged to coact with the actuating lever 43. A spring 41 is arranged to keep the antifriction roller 44 against this cam surface 51.

Directly below the collar 50 anothercoll'ar 52 is affixed to the shaft 15 and this lower collar is provided with a projecting arm 53 which is arranged to engage with the arm 48 in the manner which will be pointed out later. 60 designates a bottle stopper which I have invented and for which Letters Patent Number 829,341 were issued to me August 21, 1906. This cap comprises a disk 61 of magnetic material such, for example, as commercial tin plate, having a depending flange 62 below which are pro

eeting fingers

63, 63. A lining of compressi le material 64 such as gork is placed against the disk Within the an e.

A chute may be attached to the frame 10 as at 71 and this chute may be inclined sufficiently to allow the caps 60, when placed within it either by hand or from a hopper, to slide down to its lower end. Grooves 72 are provided in the surface of this chute for allowing clearance for the depending fingers 68,63 of the caps. At the lower end of the chute an opening 7 3 is provided. An escapement lever 74 is pivoted at the side of the chute near its lower end at 75, and its trip lever 7 6 is extended into the path of movement of apin 45 upon the feed arm 45.

A bottle stand 80 is supported in the outer end of the braeket17. By means of a spindle'8l and an adjusting nut 82 the vertical height'of this bottle stand may be varied. 83 is a bottle having a bead or shoulder 84 about the upper portion of its neck. The stand 80 is provided for the purpose of sup porting such a bottle under the compression pha'ft 34 and in vertical alinement with the atter.

eoaere The operation of this device is as follows:

Vhen the apparatus is at rest the various parts assume positions such as are shown in Fig. l. The first movement of the treadle 12 will cause the vertical rod 15 and its associated parts to be depressed. The first effect of this operation Wlll. be to remove the projecting arm 53 away from the depending portion 48 of the feed arm 45 and to allow the latter to drop down into the position in which it is-shown in Fig. 3. The next effect of the operation will be to cause the antifriction roller 44 to ride up upon the cam surface 51 and to thus swing the feed arm horizontally about the pivot 41. This will cause the cap-carrying head 47 at the end of the feed arm to be-moved into a position directlyunder the opening 73 at the end of the chute 70. At the same time the pin 45 striking against the trip lever 76 of the escapement will cause the latter to be moved and to allow oneof the caps 60 to drop through the opening 73 into the cap-carrying head 47 'The downward movement of the shaft 15 just described will bring the collar 15 down to the upper portion of the yoke 22. While the parts arein the above positions an operator may place the bottle 83 upon the bottle to be moved downward against the action of the spring 24. A ea 60 has been placed upon the lower end 0 compression shaft 34 in a manner which will be pointed out later. The downward movement of the reciprocating shaft 21 and the compression shaft 34 will continue until the bottle cap is placed upon the top of the bottle '83, and as the reciprocating shaft 21 is continued in its downward -movement the cap will be firmly pressed down upon the bottle under the action of the compression spring 36, thus compressing the lining 64. It may be seen that although the movement of the compression shaft. is arrested by the cap coming in contact with the bottle the reciprocating shaft 21 and the other parts which are associatedtherewith may continue their downward movement. This downward movement will cause the cam grooves 81 ofthe forming ring 30 to act upon the depending fingers 68 of the bottle cap and to press them inward and under the bead or shoulder 84 around the neck of the bottle. The bottle will thus be sealed and the operator may hen allow the various parts to return to feet of the upward movement of the rod 15 will be to move the portion of the cam surface 51 which pressed against the cam lever 43 in such a manner as to allow the spring 41 to return the cam lever 48 and the feed arm 45 to their original positions in aline mentwith the compression shaft 34 and in the position in which it is shown in Fig. 3.

As the rod 15 continues its upward movement the arm 53'will'come in contact with the depending arm 48 and push the latter outward, thereby raising the feed arm 45 and its cap-carrying head 47. One of the caps 60 is now in this cap-carrying head and as'the latter is raised up against :the compression shaft 34., the cap will be brought in contact with the'compression shaft, and because the latter is magnetized or is provided with a permanent magnet 37, the cap will remain upon the compression shaft during the subsequent parts of the operation which have already been described. L

The above operations may be repeated indefinitely and the caps applied to bottles rapidly because the apparatus is provided with the means above described for automatically placing upon the end of the compression shaft 34 one of the caps 60 during each cycle of operations.
