To all whom it ma l 'co'nc'e'rn Be it known that I, LOUIS a citizen of the United States, residing at Glen Ridge, in the county of Essex and State of New Jersey, have invented a new and useful Bottle-Capping Machine, of which the following is a specification.

My invention relates more particularly to bottle capping machines or the like, and especially to those adapted to put what is termed a metalliocap and seal upon a bottle.

One object of my invention is to provide a machine of this class which will automatically adjust itself to bottles of various heights, so that the insertion of abottle of height will not be liable to'be folgreater breakagecf the bottle or 1n ury lowed by to the machine.

A further object is to provide a machine in which the capping dies will automatically adjust themselves to bottleswith 'n'ecks or mouths of various sizes and diameters and having other irregularities.

' Afurther object is to provide; a machine with'a hopper and a chute leading from the hopper, and having one end secured to the die head whereby delivery of the caps or seals is made more eflicient.

A further object is to provide a machine which is entirely automatic in all its operations, especially with regard .to the rever: sals of the capping pistons at both ends. of their line of movement.

' ..A further object is to provide, a machine which may be operated at high speed without danger of doing injury either to the bottles or machine.

Further objects are to provide a machine with a uniform and simple. feeding mechanism and a machine in which the dies will act upon the bottle and cap with a uniform pressure, irrespective of irregularities in the bottle.

Further objects are to provide an arrangement for easily controlling the speed of such v -.proper position 'on table 2.

a machine, and to provide a machine which is simple in construction, easy to manipulate and not likely to get out of order. I

Further objects, features and advanta es will more clearly appear from the detai ed, description given below takenin connection with the accompanying drawings which form a part of this specification, but it is to be understood that changes, variations and H. BRIXKMAN;

be resorted to, which come i I I l i l modificatlonaea n of the claims hereuntoapwithin the scope."

The operation of the described embodiment of my invention is as follows: The bottles having been filled by a filling machine, are delivered to the table between fences 6 and 26/, the latter guiding them off of the filling machine platform and into po-. sition to be operated upon by one of the finers 16 which carry the bottles into position Assam ing that a bottle has just been capped and head is ascending from the upward movement, the position of the parts will be as shown in the drawings (Figs. 3, 4, 6 and 13 being the more important figures to be considered in the followinestatement of operation). In this position of the apparatus the fluid is being admitted through in-.

'inder M3, and is let port 77 into cylinder 46 and is exerting downward pressure upon the hold-down-cap piston 52 to hold it in the lower end of cylexerting pressure upon the upper end 58 of cylinder 46 and upon the cup washer 69, to force the main piston head 72 and its attached capping parts upward, the valve 60 during this time being closed to prevent the flow of fluid to the upper surface of the piston head 72, and the valve 62 being open to permit the fluid in the upper end of cylinder 40 above the piston head, 72 to discharge through said valve 62, ex haust passage 78, and through pipes 7l to the exhaust chamber St}, and thence through the exhaust port'78. Referring to Figs. 3 and 4, as the capping 'headcontinues to ascend, it is guided vertically by the engagement of pin 20 with the slot 23 in sleeve 12; and roller 21 mounted on said pin engaging the upper curved portion of slot 22 in the sleeve 11 (Fig. 4) causes the sleeve 11 and the finger 16 to be moved to the left a sixth of a revolution, thereby bringing the next filled bottle into position on the rubber pad.

,The capping head cylinder L6 continues to placed under slight tension, but this was insufficient to open valve 60 against the fluid pressure exerted on the lower surface of the valve, and the valvethus remained closed as stated, until spring 93 on rod 61 engaged the lower end of sleeve 79, whereupon valve 60 ,was immediately opened and valve 62 immediately closed with a' 'quick action. This feature of having these valves,60 and 62 held open until the limit of the ,desired movements of the parts and then quickly closed is very important,

that without some such provision, justbefore the parts reach their extreme upward movement, valve 62 would commence to close and valve 60 commence to open, whereupon fluid would l'low directly from cylinder l6 through the partly opened valve 60, passage 73, passageways 66, 67 (Figs. 8-l0), into the upper end of cylinder 40 and througl'i the partly closed valve 62 and pipes 74 into the exhaust chamber 80, whereupon the apparatus might stop. The closin of the valve 62 cuts off the exhaust of iluid from the upper end of the cylinder 40 above the head 72 through passage 73 and pipes 74, and the opening of valve'60admits fluid openings 66, 67

since it will be seen" through junk piece and head 72 and opening directly into the upper end of cylinder 4L0 above head 72; whereupon thehead 72 with the attached cylinder 46 and cap-' ping parts is moved downward due to the greater efi'ective area of the upper surface of head 72 presented to the fluid pressure as compared to the effective area below said head. The head 72 with its capping parts continues to descend with the respective capping parts remaining in their relative positions until cap-hold-down :19 presses the cap upon. the bottle (a cap having in the meantime passed through cap chute Sfl in position in cap holder-81 to be pressed upon the top of the bottle bycap -hold-down head 49), whereupon the downward movement/of the cap-hold-down piston t8 is arrested, but capping head 72, carrying the" cylinder 46 with its lower cylinder head 47, carrying the crimping dies 95, continues to descend with respect to the cap-hold-down piston 48 until the-valve 60 is closed and valve 62 opened by the compression of spring 92 due to relative movement between the cap-hold-down piston 48 and the cylinder head 47. The crimping dies 95 are at all times forced'inwardly by the fluid pressure which flows from the niain cylinder 40 through passage 102, passage 101, into the spacesback of the piston 96, so that the crimping dies asth'ey are brought down to the cap at once force the rim or flange inward by fluid pressure to crimp the cap beneath or around the lip or crown of the bottle.

The valve 60 having been closed and the valve 62 opened as a result of the relative movement between piston 48 and head 47, the fluid above the main cylinder head 72 is now exhausted through valve 62 and pipe 74 into the exhaust cylinder and the head 72 carrying the cylinder 46 and its head 47 is now moved upward while the cap-hold-down piston 48 remains firmly pressed upon the cap by fluid pressure on piston head 52 until the lower side of the head 52 of this piston is engaged by the upper end of the cylinder head 47. This 1 relative movement is sufficient to permit the .capping die to be withdrawn free of the bottle before the cap-hold-down is lifted from the cap, whereupon a cap is immediately fed into position in'the cap holder 81 for the next capping operation. The capping head parts all continue to move upward tcgether until spring 93 again engages the lower end of sleeve 79, where-- upon valve 2 is immediately closed with a quick, sudden movement and valve 60 similarly opened, whereupon the parts commence to dli-scend to capthe next bottle, etc.

From the previous description of the operatim ol" the parts it will he =uuler stood that should no bottle he placed under the capping head, the downward movement of the parts will nevertheless be stopped and the upward movement commenced by the closing of valve 60 and the opening of valve '62 by the engagement of reverse stop 63 at the upper end of rod'61 with spring 94 at the upper end of sleeve 79, which; takes place when the mainpistcn'head 72 reaches the lower extremity of its desired travel, givingvalve rod 61 a quick upward thrust to operate these valves, 3

It will beobserved that; the adjustable valve operating rod 53, carrying the spring 92 at its upper end, is adjusted according to the height of the" caps, so as 'to permit such relative movement between piston 48 and head 47 as will allow the die 95 carried by the head 47 to pass down to the side of the cap so that it will be in position to.

crimp the cap and clench it on the lip or rim of the -bottle. It will also be observed that the cap is pressed down upon thevbottle with automatically regulated pressure, and that fluid pressure is continuously exerted upon piston head 52 to press the cap firmly upon the battle, not only during the time while the-cylinder head 47 carrying the dies ing the cap around the bottle ip, but also is descending and while the dieis are crimpduring the withdrawal of the d'es from the cap by the upward movement of cylinder head 47 and until the dies are lear of thecap, at which time the upper end of the cylinder vhead 47, by engagin the lower surface of the piston head 52, wi l withdraw the cap-hold-down member 49 from the cap.

It will also be noted that tll e pressure with which the dies act to crimp the caps on the bottles is determined by the pressure at which the pressure relief valve 87 is set to operate to permit the fluidl, to pass through the bypass pipe to the liischarge pipe 90. The speed of the ap largely determined by the difiie rence in pressure at which the pressure reli' f valves 87 and 88ers set to open, so that he speed may-be regulatedwithout changing the pressure with which the dies act, and vi e verse.

From the above it will be clear,'that I have provided a machine'of the cgass de-. scribed in whlch the reverse move lent 1s dependent upon a predetermined ielative movement between the two fluid plressure operated elements, so that if irregular bottles of different heights are brought into operative position in the machine the capping mechanism is automatically adjusted to all such bottles and there is no te dency to break the bottles or injure the machine. Thus, as sohn as the crimping dies pass a certain distance beyond the top of the hot.-
