Briefly stated, the machine embodying the invention which is shown in. the drawings includes an intermittently rotatable table I upon which the bottles or packages to be filled are placed and which is adapted to be moved vertically to place the bottles supported thereby into operative relation to the filling devices and the closing or capping devices, all of which devices are preferably mounted on the base of a tank containing a supply of the liquid with which the bottles are to be filled. The machine shown in the drawings is primarily intended for filling and closing milk bottles, but it willbe understood that the invention is not intended.

to be limited to machines for operating on milk bottles but may be used for filling and closing receptacles or packages of other kinds and the word bottle, hereinafter used for convenience, is intended to apply to receptaclesor packages of all kinds. The machineas shown is intended to be used for filling and capping or closing the bottles, but it will be understood that the bottlecapping on closing devices may be omitted if desired, or the machine may be used only for capping or closing bottles. T

A represents the base or pedestal of the machine which may be of any suitable or desired form 5r construction, that shown including a substantially annular pedestal portion, the lower'edges of which are adapt ed to rest on the floor or other foundation. The pedestal is provided-near its upper por' tion with. transversely extending members a which are preferably formedintegral with the pedestal portion and on which some of the parts of the machine are supported. A substantially upright hollow column or post a is also arranged on the transversely extending members, being, in the construction shown, driven into a central hole in the transverse members and held in place by a nut a On'the upper end of the post a a tank or container B for the milk or other substance is supported by means of a spider or frame 6 or the, like secured to the upper end of the pillar or post a. C represents a This tashaft D.

Power is transmitted to the machine by any suitable means, to rotate a main drive I In the construction shown this shaft is journaled on a base plate or mem- -ber 03 suitably secured to the base or pedestal A and extends out of the base and is provided at its outer end with tight and loose pulleys d (Z by means of which the machine may be driven and stopped. Any other means for driving the shaft D may be provided; The shaft D has a worm d which is rigidly secured thereto and which is adapted to drive a worm'gearal secured on a shaft d. This shaft is provided atone end with a cam E adapted to cooperate with an anti-friction roller e' secured at the base of a plunger 6 suitably guided in the lower portion of the hollow column or post a. This plunger is held against rotation by means of a pin 6 extending through slots e in the fixed hollow post or column a. The pin e also acts as the medium for transmitting reciprocatory movement from the plunger 6' to the table C. For this purpose the table is provided with a hub portion F having an annular groove or depression in which a bearing ring f is arranged. The ends of the pin 6 are secured to the bearing ring f so as to transmit reciprocatory movement to the'hub F, which is j ournaled on the outer periphery of the upright post or member a, and also to ermit the hub ,F to rotate relatively tot e ring f and pin e Means of any other suitable construction for transmitting reciprocato'ry movement to the table may be employed.

In order to intermittently rotate the table, the following mechanism is preferably provided: G represents a- Geneva wheel which, in the construction shown, is provided With four slots 9' and-which is rotatably mounted on a stud shaft g secured on the base plate d. The Geneva wheel G is actuated by means of a roller 9 which is journaled on a pin 9 secured on the cam E. Consequently the rotation of the shaft (1 causes an intermittent rotation of the Geneva wheel G, which is secured toa beveled gear g meshing with a beveled gear 9* secured on an upright shaft 9 The shaft 9 extends through the cross member a of the pedestal A and at its upper end is provided with a pinion h meshing with a gear H which is preferably formed integral with the hub F of the table C. The gear H and. pinion h are preferably provided with wide teeth so that the teeth will remain in mesh during the reciprocatory movement of the hub F and the gear H connected therewith. The Geneva wheel and gears are preferably so proportioned that at each actuation of the table C the bottles are advanced through a space equivalent to the space occupied by two bottles;

In order to prevent the table C from turning after the roller 9 has disengaged the Geneva wheel G, a gear lock H is preferably provided which is rigidly secured on a stud or post it, also rigidly secured on the cross member a of the base. The gear lock H is provided with teeth adapted to mesh with the teeth of the gear H when the same is raised and thus prevent the gear from turning. Any other means for intermittently rotating the table C through a definite distance and for holding the same against turning while the same is moved vertically may be em loyed.

In order to rea ily adapt the machine to operate on bottles of different sizes, means are provided for adjusting the table C vertically relatively to the hub F. In the construction shown for this purpose the hub F is provided with a threaded portion 2' adapted to engage with a correspondingly threaded portion of the table, so thatthe table may be raised or lowered by turning the same relatively to the hub F. Any desired means may be provided for holding the table in the various positions corresponding to the sizes of the bottles to be operated upon. In the construction shown for this purpose, a plunger I is arranged in a tubular housing 2" preferably formed integral with the table C, and is pressed by means of a spring 2' toward the hub F. The hub F is provided witha series of holes 71? into which the .plunger I may enter to hold the table in correct position relatively to the tank B for operating upon bottles of different sizes. For example, if the machine is intended to operate upon quart, pint and half pint bottles, the lowest of the holes i will be so placed as to properly position the table 0 relatively to the filling and capping devices when used in connection with quart bottles. The intermediate hole will be correspondingly positioned for pint bottles and thev upper hole form K formed integral therewith below the upper edge of the flange 7a. In placing the bottles upon the platform they are placed extend upwardly from the table and which assist the operator in properly positioning spout Fig. 1,

the bottles so that the same will come into proper operative relation to the filling or closing devices. The platform is preferably inclined inwardly so as to drain any liquid from the exterior of the bottles, drain holes k being permit any liquid which may be spilled to drain into a trough k in the pedestal: A. may be employed to drain the liquid from the trough 70 into any suitable waste receptacle. The platform K is preferably provided with grids k or the like upon which the bottles stand, the grids being substantially horizontal so'thatthe bottles will be presented in proper relation to the filling or closing devices.

In order to enable the machine to operate on bottles or receptacles of different diameters, the table is preferably provided with an annular bottle holding plate or member having outwardly extending projections Z which are adapted to form with the positioning flanges 7c pockets for the bottles. If desired, spring holding members Z may be provided on the projections Z which yield ingly'press the bottles against the position ing flanges k. The annular plate or memer L is so arranged on the table C as to be ad ustable circumferentially so that the projecting portions Z or the springs Z, in case,v

the latter are used, may cooperate with bottles of difierent sizes. Any suitable means may be employed for holding the annular member L in the desired position. In the construction shown for this purpose, a set screw Z is employed which extends through the annular member L and which is adapted to engage with one or another of the threaded holes Z arranged in the table C.

The actuating mechanism of the machine is preferabl so arranged under the base A and table that none of the mechanism is exposed and that the mechanism is protected from moisture when the machine is washed.

This isdone in the construction shown'by providing the base A with an upwardly ex: tending flange L which is preferably formed integral with inner edge of the trough k This flange is preferably arranged within the flange k of the table so that these two flanges prevent any liquidfrom injuring the parts of the driving mechanism arranged between the base and the table.

M represents the filling nozzles or devices which are secured on the base of the tank or reservoir B and which may be of any suitable or desired construction and of them selves constitute no part of this invention. Only one of'these devices is shown in F igs. l and 2 but, as indicated in Fig. 5, six of provided at intervals which the base adjacent to the a nozzle, a valve is opened which permits.

liquid to discharge from the nozzle to the bottle, the valve being closed as soon as the bottle is removed from engagement with the nozzle. The bottle-supporting platform K is, in the machine shown, divided into twelve spaces or and since the bottle-supporting plate is advanced through a distance corresponding to two of the compartments at one time, two bottles at a time can be placed on or taken off the machine. By providing six filling devices, these the first pair of-filling devices will partly fill .two bottles, the second pair will fill the bottles approximately with the desired amount of liquid, and the last two devices will complete the filling of the bottles with compartments for bottles devices can be so'arranged that of the tank or reservoir B. Two of these closing devices are provided which place the caps or other closing devices on two bottles at a time after the bottles have been filled. By means of this arrangement, when su fficient bottles are placed on the table, six

bottles are being filled and two bottles are .e table is raised by the cam E. Any otherttype of bottle filling or bottle-capping and closing devices may be employed, and any desired number of filling devices andclosing devices may be provided.

The spider b on which the tank B is mounted, is preferably loosely ournaled on the upper end of the hollow column or post a, so that the tank or the bottle filling and closing devices mounted thereon may be turned to any desired position relatively the base of the machine, and a set screw or analogous device m is provided for securing the spider in the desired position relatively to the column or post a. By means of this construction any part of the bas of the machine can be used as the front of the machine, so that the tight and loose pulleys d d or other means for driving the machine closed each time th .may be located at the sides or back ofthe and to be connected with'the source of power without necessitating any changing or re-v building of the machine to place the pulleys in any particular position in which they may be most conveniently connected with the line shaft. I

' In order to prevent the dripping of the filling devices from soiling the exterior of the bottles or other receptacles, means are preferably provided which move into oper vided which, in the construction shown, are

trough-shaped and are adapted to conduct any liquid drippingfrom the filling devices into a trough n from which the liquid may be conducted any suitable means (not shown) to the. trough 10 formed in thebase of the machine, or if desired, the liquid -'from the trough a may be otherwise disably tically in a guide bearing p secured to the posed of. The trough n, in the construction shown, is secured to the spider b by means of straps or supports a and the radial arms or trough-shaped members N'are mounted to swing about the axis of the machine into and out ofaoperative relation under the filling devices M. In the construction shown for this purpose, the radial arms N are secured to an arc-shaped bar n which is secured to arms a extending outwardly from a collar 0 rotatably mounted on the hub of the spider b, a collar 0 secured to the hub of the spider serving to hold the oscillatory collar O in place. Means for causing the oscillation of the collar 0 and the arms N connected; therewith are prefer constructed as follows: I

represents a bar which is movable verspider b. The bar P is provided with an inclined face 70 adapted to engage a roller p pivotally secured on the collar0. A spring p draws the collar 0 into a position in which the ,roller bears against the reciprocatory bar P. When the bar moves upwardly the inclined face thereof will cause the collar 0 to rotate in such a manner as tomo ve the radial arms N out of operativerelation to the filling devices M, and

when the bar P descends, the spring 72 movesthe radial arms N again into operative posit10n under the filling devices M- to catch any devices The reciprocatory movement of the bar P may be effected by means of the hub F and for this purpose the lower end i the radial arms N are moved from a position underneath the filling devices to permit the of the liquid which may drip from the filling for advancing the table,

bottles to move upwardly into operative relation thereto. As the table C descends and the bottles move away from the filling devices, the arms N again move into a position underneath the filling devices, in which position they remain while the table is rotated to advance the bottles to their next position.

In the operation of the machine described, the table C is raised by means of the cam E to place the bottles into operative relation to the filling devices or closing devices. After the cam has moved into a position in which the table C is in its lowest position, the roller 9 of the cam engages the Geneva wheel G and through the medium of the bevel gears g g and the gears hand H, the table is rotated to advance the bottles to their next position, after which the cam again actuates the plunger 6' to raise the table. As the hub portion of the table is raised, the gear lock H engages with the teeth of the gear H so as to prevent the rotation of the table while the roller g is out If it isdesired to change the machineto operate upon bottles of a different size, the plunger I is withdrawn from the hole i in the hub F and the table is rotated relatively" to the hub until the plunger I enters into another of the holes 71 corresponding to the size of the bottles to be operated upon, the table being raised or lowered by means of the screwthreaded portion i of the hub F and the correspondin ly threaded portion of the table G. In or er to set the machine to operate on bottles of different diameter, the annular plate L is adjusted so that the projections Z thereof form with the projecting flanges, k of the table, compartments of the correct size to retain the bottles, and the annular plate is then locked in the correct osition by means of the set screw.- Z When it is desired to change the frontof the machine, it is merely necessary 'to loosen the set screwm and to turn the container B with the parts connected therewith to any other position in which the'bottles will come lnto proper relation to the filling and capping devices when the table C is raised.

1 The machine described has the advantages of being. compact in construction and rehable and quick in operation. The bottles can be readily placed in the correct posit on on the table, which insures proper operat on of the machine. Since no dripping of the filling devices can soil the exter or of the bottles, the machine is also sanitary. By employing a Geneva wheel in the mechanlsm the table is started and stopped gradually and moves at its greatest speed half way between 1ts starting and'stopping ositions. The feed ng of bottles to the mac inc and the removing of the same from the machine is greatly facilitated by the fact that the empty bottles are fed to the same part of the machine at which the filled and capped bottles are delivered,

so that one man can operate the machine.
