This roller conviews taken on the lines 6-6 and 1-1 of Fig. 4, tacts a suitable cam member 25 during the portion of the travel of the crowning mechanism.
For a more detailed description of the construction and operation of the above parts reference may be had to my co-pending application filed May 11, 1949, hearing Serial No. 92,546 heretofore referred to.
Supported, beneath the crowning throat is a crown rest 26 which is supported from the crown throat by means of suitable supporting pins 2! extending through lugs in the crown rest and locked in the ears 28 on the crown throat by means of screw threads. The lower ends of these pins 21 are keyed, as at 27, to suitably support the crown rest and the upper surface of the top wall of this crown, rest has sealing engagement with the crowning throat through the medium of a sealing gasket29, The top wall of the crown rest is provided with a crown support 39 on which the crown is: adapted to be deposited by insertion through the slot in the crown throat. The crown. rest is provided with a centering bell 3| having. a tapered throat. The centering bell takes the form of an annular ring reciprocally mounted within the crown rest and held in position by athreaded collar 32 threaded into the crown rest andprovided with a shoulder 33 adapted to be engaged by the shoulder 34 on the bell. The bell Si is biased in a downward direction by a coiled spring 35 and interposed between this vertically movable bell 38 and the bottom base of the top wall of the crown rest is a sealing ring 36 which is substantially U shape in cross section and which, when contracted, sealingly engages the neck of the bottle projecting therethrough and into a position to receive a crown supported on the crown support as.
When a bottle is projected through the ring 36 and into a position to receive a crown supported on the crown support 39, a vaccum is drawn in the crown rest chamber, accommodat ing the sealing ring 35, through a suitable port 37 and which tends to raise the bell 3i compressing-the sealing ring 35and contracting the same into sealing engagement. with the neck of the bottle. At the same time a vacuum is drawn in the crown throat chamber through a port 38, which throat chamber has previously been sealed b the stopper 2d, so that immediately before the engagement of the lower end i of the plunger with the crown, to hold the same upon the top of the bottle, all air Within the crown throat chamber is exhausted and such air as iscontained in the top, of the bottle is likewise exhausted. Upon the descent Of the plunger It the crimping ring 13 crimps the lip of the crown about the neck of the bottle and the bottle is thoroughly, sealed While still under a vacuum.
Immediately upon the crimping of the crown the vacuum, operating upon the ring 38, is released thereby releasing the neck of the bottle and immediately thereafter the vacuum in the crowning throat chamber is released, by placing the same in communication with the atmosphere. Before the bottle is removed from, the throat, however, compressed air is momentarily introduced into the throat for blowing out any particles which may have occurred therein and also into the sealing ring 35 to tend to expand the same and force the tapered throat 3! downwardly.
For controlling the drawing of a vacuum in-the crown throat chamber and in chamber accommodating the sealing ring 36 and the release thereof and the admission of air under pressure thereto, I provide what may be termed a slide valve, this slide valve consists of a non-rotatable valve ring 39 surrounding the hollow support I and supported upon a clamping ring 40. This ring 39 is provided with an inlet stem 4| connected by a suitable conduit 42 leading to a source of vacuum. The stem 4| is vconnectedthrough a suitable conduit43 with anannular groove 44 formed in the top face of the ring. The ring also is provided with an annular groove 45 which in turn is connected by a suitable coupling 46 with a conduit ll leading to a source of air under pressure. Cooperating with this ring 39 and disposed above the same, is a second ring valve 48 which is provided with'a port 49 extending to the face thereof'and in turn communicating through a conduit 50 with the port 31 leading to the sealing ring 35. This ringvalve 48 is also provided with a port 5! extending to the face of the ring valve 48 to which port 5| is connected by a conduit 52 with the port 38 leading to the crown throat chamber. Thering valve 58 lies face to face with the ring valve 39, but rotates relatively thereto and with the crowner.
As the crowner and with it the ring valve 48 rotates, the port 49 is first placed in communication with the groove 44 and accordingly a vacuum is drawn in the sealing ring 36 to seal the neck of the bottle. Immediately thereafter, however, the port 51 moves into communication with the groove 44 and the crown throat chamber is placed in communication with the source of vacuum, thus drawing a vacuum in the crown throat chamber. As the parts continue to rotate, the crown is sealed onto the bottle and immediately thereafter the port 49 moves into communication with groove 53 in the face of the valve ring 39. This groove, through a suitable port 54, communicates with the atmosphere so that as the port 49 moves out ofcommunication with the groove ldand into communication with the groove 53, the source of vacuum isshut oil and the sealing ring is placed in communication with the atmosphere-thereby relieving the sealing pressure of the sealing ring on the neck of the bottle. Almost immediately thereafter, the port 51 moves out of communication with the groove 44 and into communication with groove 53 and therefore in communication with the atmosphere so that the vacuum is releasedin the crowning throat chamber.
During the continued rotation of the parts, both ports 49 and 5| move in continued communication with the groove 45 in the ring 39 which, it is to be noted; is placed in communication with a source ofair under pressure, which air will tend to blow out of the crown. throat chamber any'foam, which may have been drawn therein, and any foreign particles. Likewise the air under pressure will tend to assist the coil spring 35 in moving in throat 3| back to its initial. position.
While I have shown one set of ports 49 and 5| in the valve ring 48, it will be understood; that there are as many of these sets of ports as there are provided crowning heads of which I have illustrated in the drawings only one.
It will also be understood that the crowning heads are adapted to rotate about the center post 2 in an orbit and during such rotation the crowning operation takes place.
I claim:
