ppn'caiitii inea Jute 15, wo'. 1 serai No. 20,404. .No mada.)
To @ZZ whom it may concern.-
Be it known that I, FRANK O. WOODLAND, a subject of the King of Sweden and Norway, residing at l'Vorcester, in` the county of Worcester and State of Massachusetts, have invented new and useful Improvements in Crown-Placer Mechanism for Bottle Filling and Stoppering Machines, of which the following,togetherwith the accompanyingdrawings, is a specification sufficiently full, clear, and exact to enable persons skilled in the art to which this invention appertains to make and use the same.
My present invention relates to certain novel combinations and improvements applicable to crown-placing or feeding mechanism of that class wherein an elevating crown-carrier is employed by which the bottle-stopper.
crowns are upwardly inserted within the throatway of the crown-setting head of a bottle-stoppering machine such as employed for bottling aerated beverages or liquids under pressure.
The prime objects of my invention are to render the mechanism compact in structure, light and easy for operation, and convenient for attendance and adjustment.
The minor objects and improvements or novel features comprised in my present invention are specifically set forth and explained in the following detailed description of mechanism embodying the same, the particular subject-matter claimed being hereinafter definitely specified.
In the accompanying drawings, Figure l represents a rear'elevation view of a crownplacer mechanism embodying my invention. Fig. 2 is a separate rear view of the reciproeating elevator member, its guide, and lifter devices. Fig. 3 is a top end View of the same. Fig. 4 represents a front view of the crownplacer mechanism, its relative position upon and connection with the crown-setting machine being indicated thereon. Fig. 5 is a detail plan view showing the top end of the frame and adjacent parts. Fig. 6 represents a plan view, partly in horizontal section, at line X on Fig. 4 near the upper part of the frame Fig. 7 is a` detail horizontal section showing the lower part ofthe frame and the operator-lever. Fig. 8 is a detail plan view of the crown-carrier ycon'ne'ctirig-arms and lifter devices. Fig. 9' is a' vertical central section through the head of a lling and stop-` pering machine and crown-carrier appliances; illustrating the combined means for holding the crowns horizon tal while entering and passing the gasket-ring and within the throatway. Fig. 10 is a bottom view of the end collar and.A throatway. Fig. 1l illustrates a modification in the structure of the feedway-conduit and the carrier-guard. Fig. 12 is a sectional view showing the elevator and operator-lever in an edgewise elevation view, and Fig. 13 shows the guard fixed on the elevator.
In the crown-placer mechanism, asshown in the drawings, some of the parts are constructed and arranged to operate as described in my prior Lettersl Patent No. 665,623-, and such parts will be understood Without extended description thereof herein, the present description serving to p oint out and explain the new invention and improved features combined therewith.
. Referring to the drawings, the part marked A represents the elevator-slide or upwardly and downwardly moving member, bywhich the crown-carrieris raised and depressed, and
B denotes the frame for supporting the oper-.
ating parts and connecting the mechanism with the upwardly and downwardly movable crown-setting head K upon the bottle-stopperingmachine. ThisframeBisbestmadeas a single casting of the general form and arrangement shown, having connected upper and lower portions for supporting the ends of the upright guide-rods B B3, and for itsl attachment to the stoppering-machine head there is provided an ear or bracket b, that rests upon and is clamped to the wing por'- tion of the head K by the nut N or other edicient fastening device,.and also a bearing or clasp b', that embraces the head-supporting rod K2 and is clamped thereto at a position somewhat below said head or its wing portion.y The ear b and clasp b axially center on the rod K2 and afford an upper support by said ear and a lower support by said embracing clasp, whereby the crown-placer mechanism is secured and held with lateral firmness and so thatthe working parts of the crown-placer are maintained in axially parallel alinement or correct relation to the axis ofthe stopperingmachine head or its throatway, into which the crown-carrier is to properly enter. The frame I3 is also provided at its top with a projection C', having a hooked end for sustaining one end of the mainspring C, which exerts the actuating power for placement of the crowns.
According to my present invention the elevator A is constructed as a tubular body mounted to slide upon a stationary guide or rod B', supported in the frame B. Said elevater-slide is provided with the rigid laterally-projecting arm A', that connects with and operates the crown-carrier and has the catch-lng A3 thereon that coacts with the lug or detent of the let-off or trip lever. Upon the elevator A, I arrange a lifter or engaging device, which preferably consists of a short arm E, pivoted at a to an ear formed on the elevator-slide body and having at its swinging end a stud and roll E'. A stop-shoulder or projection a5 is also formed on said body above the arm E and against which the upward swing of the arm is arrested. Said arm is free to swing downward, but is normally held against the'stop a5 bya suitable spring, as D, one end of which is connected with a hook on the hub of the arm and its other end connected with the frame or arranged in other suitable manner forgivinga yielding resilient action to said lifter-arm and its roller-stud.
The spring D serves for depressing the elevator-slide A, as well as for controlling the arm E, or, if preferred, two separate springs can be employed, one for the lifter-arm and another for depressing the member A, which latter can be located as at D', Fig. 8, or the member A and carrier c an be made to drop by gravity alone or without the aid of any depressing-spring. The foot of the elevatorslide is stepped upon an annular cushioningwasher z, of leather or other suitable semielastic'material.
F indicates a swinging lever or operator member pivotally fulcrumed upon the frame B by the axis pin or stud G and comprising, as shown, an upper arm provided with a cam flange or surface F', that engages the lifterstud E', connected with the elevator slide or member A, and a lower arm provided with a contact-foot or bearing-roller F2, that coacts with the stationary abutment-surface H upon the stand or foot block H2, which is attached to the horn K3 of the crown-setting machine. The lever F is also provided with an arm F3, to which one end of the mainspring C is connected, the other end of which spring is connected to the projection C on the frame. The mainspring C is strained to act by contractile force to move the lever F in opposition to theabutment H, and there is provided a stop G' or means for arresting the movement of the lever F and spring C at the required limit for their action. The cam surface or ange F' is preferably formed with a retreating or varied curvature or to give a shorter degree of throw toward its latter end w, so that the cam-power is concentrated or increased as the crown-carrier approaches the dies W and as the spring C contracts toward its limit of exhaustion. This renders the movement of crown-carrier relatively slower, but more powerful, while within the| throatway; but it performs the early part of its movement where there is no resistance with ease and despatch and attains the effective operation with a mainspring of less strength than would otherwise be required. The roller-stud or engaging detent E', being arranged upon the short swinging arm pivotally attachedv to the elevator member A, is adapted, by means of the rigid stop above it and its yielding spring at the other side, to positively engage the cam-ange F and effeet the upward lifting of the elevator-slide or carrier-actuating member A when the lever moves in one direction; but by yielding the rollstud E' passes under said lange when it moves in the opposite direction, thus permitting the lever to recover its prime position.
A very light tension depressing-spring D is sufficient for the reciprocating elevator A and its lifter, and a single spring can perform the double function of controlling the arm E and depressing the elevator and crown-carrier devices. The gravity of the parts acts in the same direction with said spring and will effect the drop motion The construction and arrangement of the trip or let-off lever L, its return-spring L',
`arm and stop-finger L2, and the latch-lug L3 are substantially the same as disclosed in my prior Letters Patent, these parts being united by an upright bar L5, hinged to the supporting-frame, as at e e', and forming a trip or let-off device that can swing laterally outward when a capped bottle is removed from beneath the cappingon head and contacts with the lever L.
The crown-carrier devices M, comprising the swinging arm M', upright supporter or finger-rod M2, tip-end plate m, spring m4, hingng connections on the guide-rod B3, controlling-cam 10, roller-stud 1l, and returnspring l5, are severally constructed and arranged substantially as described in my prior Letters Patent,
In my present invention I provide, in combination with the crown-carrier, a feedway conduit or mouthpiece I and a covering-guard J for conveniencing the handling ot' the crowns. Said mouthpiece I (see Figs. 4, 5, and 6) is formed with an internal channel adapted for the edgewise passage of crowns singly and is arranged in inclined position, supported in the present instance upon the swinging trip-lever frame, its mouth opening at I', at or near the top thereof, and its lower end t disposed at a position for sliding a crown diagonally into the crown-carrier cup and depositing it in proper position over the supporting-plate m of the inserting finger or rod M2. The upper side or plate portion of the IOO IIO
delivery end of the inclined mouthpiece is extended horizontally over and beyond the rim of the crown-holder, at a slight distance above the same, forming anindependent overlying guard J, by means of which all liability of displacing the crown at the quick start of the crown-carrier is prevented. An opening in the upper sideof the mouthpiece enables the attendant toobserve the position of the crown therein. The upper part of the mouthpiece or feedway-conduit I may be attached for support to the upper portion or springconnecting arm L2 of the let-oft mechanism, as best shown at n', Fig. 5, while the lower part of said mouthpiece can be attached to the lug L3, as indicated at n in Figs. 4.- and 6,
or to the upright bar L5, on which said lu g is.
formed. When thus supported, the mouthpiece or feed-conduit I and guard J can swing away from their normal position when the trip-leverL is swung outward for starting the crown-placing mechanism.
Instead of attaching` the mouthpiece I to the swinging trip-bar L5 for its support it is obvious that said mouthpiece can be supported on the frame B, if desired, and I have illustrated such an arrangement in Fig. 11, in which instance the top I of the mouthpiece is below the level of the spring-connecting arm and the attaching-bracket n2 is disposed in a manner that permits the trip devices to swing outward while the mouthpiece remains stationary.
If desired in any instance, the guard .I can be made and used in a separate piece from the mouthpiece or conduit l. An illustration of such construction is shown in Fig. ll, wherein the guard is shown as attached t0 the stationary frame; but I prefer to have the guard attached to or retractable by a movable part of the mechanism, as when connected with the trip -lever devices or, as shown in Fig. 13, attached to the elevator A to move upward therewith as the carrier-cup starts. In this case the guard can be set closer to the top of the carrier-cup.
The lateral swing of the crowncarrier avoids contact ot' the guard J and carrier-top as the latter moves toward the head K when discharged.
With a mouthpiece substantially such as described the care and labor of loading the crown-carrier are reduced to a minimum. It is simply necessary to drop the crown S edgewise into the mouth, as indicated in Fig. 4. It then naturally falls in to proper place. Auother advantage is that the hand of the attendant when depositing the crown is at a position where it is not liable to injury by broken glass from a bottle bursting during the process of filling-an event which sometimes occurs.
For insuring proper assemblage of the crown-placing attachment upon the'bottle lling and stoppering machine I provide the supporting-frame B with a projecting horn or tongue B2, adapted to serve as a stop or guide in the adjustment of the crown-placer attachment in relation to the crown-setting machine-head. Thus when the frame is set with the clasp b', ear b,and nut N in position the placement of the end ot the horn B2 against the side of the machine-head K brings the crown-placer mechanism into proper position, so that the crown-carrier M will swing into correct alinement with the throat-opening T. Hence an unskilled workman is enabled to readily assemble and adjust the crown-placer mechanism upon the ordinary crown-bottle-stoppering machine whereon this crown-placing mechanism is designed for use.
In the upper portion of the frame B, Iprovide a hole 0, the position of which coincides when the adjustment is correct with the opposte side of the machine-head and into which after the adjustment is effected a stud 0r key t can be inserted, which stud stands adjacent to the side of the headpiece K, (see Figs. l and 4,) and in opposing conjunction with the horn B2 retains the-frame B from being moved laterally or becoming accidentally displaced from its proper position.
In the crown-settingmachine head the spring-pressed main plungeigwhich forces the crowns upon the heads of the bottles, is provided with a drop-plunger P, that slides therein and is depressed by a light tensionspring Q, disposed in the bore above it. In my improvement this drop-plunger P is constructed so that its lower end face is normally disposed adjacent to the collar-face K or mouth of the throatway, at which level IOO said plunger-facecoacts with the tip-end plate m of the crown-carrier for 'embracing or contact with the disk of the stopper-crown S as the holder-rim is stopped at the face K of the collar.
P and the tip-end plate m, while at a position at or below the level'of the gasket-ring R, the crown S is kept positively horizontal as it is carried up through the gasket-ring and throatway into the die W, thereby preventing any liability ol the crowns'tilting or becoming diagonally displaced while going through the gasket-opening, even though the gasket may be ragged, and also insuring the square setting of the crowns within t-he capping-on die W, and hence their more perfect closure upon the bottles. f
In the operation the attendant drops the crown bottle-Stoppers S into the mouthpiece I, which loads the carrier or holder M. the head K,with the frame B, being depressed, the roller-arm F2 of the lever AF impinging on the abutment H causes said lever to assume the position indicated by dotted lines f, thus straining the mainspring C by its arm Fs and swinging its cam-flange F `over the lifter-roll stud E', the arm E yielding, as per dotted lines E11, Fig. 2, while the flange passes over it, but immediately rising in front of the cam-surface. By reason of the trip-clutch The crown-disk being thus embraced between the end of the drop-plunger IIO Then,
ISO
lugs L3 and A3 locking down the member A, on which said lifter is mounted, the roll-stud then prevents the immediate reaction of the lever, while the machine-head K is elevated to its primary position. The mechanism is now in set condition, ready for discharge. By swinging the trip-lever L in usual manner in the direction indicated bythe arrow on Fig. 6 the lug L3 is thrown off from the lug A3, releasing the reciprocating elevator slide or member A and parts connected therewith. The mainspring C then contracting moves the lever F and forces the cam-flange F beneath the lifter-roll stud E', causing instant elevation of the member A and crowncarrier devices, which are connected therewith. Vhen the crown-carrier arm M' is thus elevated, its roll-stud ll and the camsurface l0 cause the arm to swing laterally, bringing the crown-carrier into alinement with the throatway T in the stoppering-machine head K, into which the crown, supported on the tip end plate m, is inserted by the upward movement of the crown-carrier, the action of the crown-carrier arm being similar to that described in my prior application. Vhen the lever F has made its full forward movement, the cam or iange F' has raised the lifter E and member A to its full limit, and the roll-stud E is there released by the said flange. (See dotted lines E5, Fig. l.) Then the elevator and parts will drop to their primary position by gravity or aided by the force of the spring D. At the same time further movement of the lever F by the spring C is arrested by the contact of the stop device at G', As the crown-holder M enters the throatway T the crown Sis met at the entrance by the yielding drop-plunger P, and the disk of said crown is embraced between `the plate m and plunger-face and is thereby maintained horizontal orprevented from becoming tilted as it is carried upward through the gasket and placed squarely in the capping-on die XV, while the holder-rim remains outside stopped against the collar-face K. The act of again depressing the machine-head for capping the crown upon a bottle effects the resetting of the operator-lever and mainspring ready for another discharge, and the act of removing the bottle against the triplever puts the crown-placer mechanism into operation 'for repeating the movements, as above described.
The crown-placer mechanism receives its store of energy in the spring C while the bottle-capping head is doing its work by the downward movement thereof, and the crowncarrier is discharged for placing the crown within .the capping-head while said cappinghead is idle and at elevated position. Hence the lever F can perform its discharge movement without interfering with a bottle or striking the abutment H with its foot roll or arm F2.
It may be noticed that when the elevator and crown-carrier devices reach the limit of elevation the mainspring and operator-lever let go or cease to act upon them, leaving the released devices free to descend without intluence from the mai nspring tension. A very light depressing influence is therefore all sufficient for returning the elevator and carrier to primal position. Furthermore, the setting of the mainspring C is effected while only said spring is operatively coupled to the lever, the other parts being then at rest. This method and arrangement while utilizing the full power of the springs renders the machine very light running and easy of operation, thus attaining quite a saving in power.
