This .v invention relates to mechanism for capping bottles and is designed particularly with a view to its use in ca ping milk bottles.

An object of the invention is 'to l rovide a machine for this purpose which wi l be simple, speedy and accurate in operation.

Other objects and avantages will become apparent as the description proceeds.

Referring to the accompan ing drawings, which are made a part hereo' and on which similar reference characters indicate similar parts,

Figure 8, a detail of one of the pushers. 1n the drawings numeral 10 indicates a g@ milk bottle of conventional shapehaving a l'lared top 11. l2 indicates a ring which its over the top of 'the milk bottle and which is centered and held in position by means of springs 13. Mounted upon the ring 12 is a 3s series of spiral rods 14 which carry cams 15 on their lower ends which cams have sharp edges as shown at 16 :for separating the lowermost bottle cap 17 from the stack of caps 13 which are contained in a cylindrical tube 19. se Spaoed around the top of the ring 12 and secured to it'are plates 2O upon which plates are mounted blocks 21 having sloping interior portions 22 for a urpose which will laterappear. lf desired t e plates 20 and the at blocks 21 may be made integral with the ring 12. Mounted upon and closing the space between the ends of plates 2O are plates 23. These plates are notched on their inner side to receive a spindle on the lower end of the ce spiral 14 and a disk 24 is secured to or made integral with the cam 15. The cam is held against vertical movement by the plate 23. A block 25 having a ball 26iseated in a socket therein provides a ball bearing for t-he cams. The plate 24 has a cut-out portion at 27 to 55 permit the bottle caps to pass down into and e seated in the. mouth of the bottle. A space 28 is provided between the lower end of the cam and the plate 24 and the plate 23 engages in this space on the outer side and on 60 its inner side the space receives the edge of the bottle cap 17, as shown in Figure 5.

:The tube 19 has a shoulder portion shown at` 30 in which a cardboard orA other tube 29 containing the bottle caps rests. The inner @5 diameters of the tube 29 and the tube 19 at 'shoulder portion 30 are the same, namely,

slightly greater than that of the diameter of the bottle caps. Surrounding the tube 1,9 is an'operating sleeve 31. The tube 19 is pro- 79 vided with a number of lugs 32, preferably formed by punching out a portion of the metal of the tube and a coil spring 33 is seated on these lugs, and has its upper end pressing against an inner iiange on the operating 75 sleeve 31. Within the lower end of the sleeve 31 is fitted a ring34, the ring being preferably secured in the sleeve by means of screws 35. The ring 34 has a number of axial bores 36in its rim to receive the ends of the spiral so screws 14. The sides of the holes 36 are cut out to receive lballs 37 which en age in the spirals in the screws 14 to rotate t ese screws when the sleeve 31 is moved vertically. The spiral groove in the members 14 terminates sa at its lower end in a. straight groove at 38 so that when the ring 34 reaches a certain point in its downward travel further movement will not rotate the spirals 14 but will hold them in the position to which they have been moved. ao

This is the position in which the cut out portion 27 is just beneath the bottle cap so that the cap may drop upon the bottle. Positioned in notches 39 in the linner portion of the ring 34 are a number of pushing plungers 40, a5

the lungers being preferably held in the note ves by means of heads 45 which engage the inner face of the ring 34 and shoulder portions 46 against which the lower side of the ring 34 rests. The plungers 40 have their ico surface at 42 which is engaged by the lower edge of the tube 19 to move these plungers outwardly as the sleeve 31 is raised. A portion of the lower edge of the tube 19 is preferably formed with a beveled edge. as shown l0 at 43 on which edge the cam surface 42 of the plungers rides.

In operation a tube 29 of bottle caps is inserted within the tube 19 and pushed down so that its lower end rests upon the shoulder 30. The ring 12 is then positioned on the top of a bottle and the sleeve 31 is pressed down. As this moves downwardly the balls 37 acting in the grooves in the spirals 14 rotate these together with the cams 15 on their lower ends. As the cams rotate the edges 16 engage between the lowermost bottle cap and the one next above it to separate the two, the lowermost cap being held in the notch 28 and resting upon the plate 24. The remainin caps in the tube together with tube are cause to move upwardly by the upper cam surface of the cam 15. When the cams have been rotated to the position at which the cut-out portion 27 registers ust below the bottle cap the plungers l will strike the sloping edge 22 of the members 21, move inwardly, and at this time the balls 37 will have reached the straight groove 38 of the spirals 14. The spirals will therefore no longer be rotated and downward movement of the sleeve 31 will cause the plungers 40 to press the bottle cap down into the neck of the bottle as shown in Figure 6. Upon releasing the sleeve 31 the spring 33 will raise it to its elevated position and as it moves upwardly the balls 37 will rotate the spiral in the reverse direction to allow the bottle caps and tube 19 to drop down to the point at which they rest on the plateV 24. A shoulder 47 on the tube 19 also rests onthe shoulder 48 on the spirals 14. The above operation may be manually performed and by means of this device bottles may be manually capped very rapidly. `The device, of course, is not limited to its use 1n hand operated bottle capping operations but may be adapted for use with machines by means of which the simple mechanical movements necessary may all be easily carried out.

It will be obvious tov those skilled in the art that various changes may be made in my device without departing from the spirit of the invention and therefore I do not limit myself to what is shown in the drawings and described in the specification, but only as indicated in the appended claims,

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is:
