RICHARD BRIGGS, OF NORTH ADAMS, MASSACHUSETTS.

APPARATUS FOR FILLING BOTTLES.

T 0 all whom it may concern:

Be it known that I, RICHARD BRIGGS, a citizen of the United States, residing at North Adams, in the county of Berkshire and State of Massachusetts, have invented new and useful Improvements in Apparatus for Filling Bottles, of which the following is a specification.

My invention relates to an apparatus for filling bottles, and particularly to apparatus for filling milk bottles, though of-course it will be readily seen that the apparatus may be used for filling bottles of a variety of shapes and forms and for filling them with liquids other than milk, or with some ma terial other than a liquid.

My apparatus is designed especially to secure the following results. First, to enable a number of bottles to be successively filled in groups from a tank above them. Second, to fill bottles of various sizes. Third, to fill these bottles at the same rate so that each bottle of a group will be quite full and will not be short or excess measure. Fourth, to make the apparatus as nearly automatic in its operation as possible. Fifth, to make it as durable, efficient and at the same time as sanitary as possible.

To these ends, my apparatus consists of a tank supported on a carriage adapted to travel over a track above the bottles. The tank is provided with a row or rows of valves operated by suitable mechanism carried by the carriage. Means are provided on the carriage for engaging the rails at certain positions of the carriage to accurately stop and position the carriage just over a group of bottles. The means for operating the valves has an interconnection with the means for stopping the carriage such that the entire carriage and tank is bodily moved-by a suitable weight attached to the carriage and passing over a suitable pulley whenever the valve operating mechanism is operated to close the valves. In other words, my apparatus comprises a table for supporting the bottles in groups, a track above that table supporting the carriage carrying the tank of liquid, valves on the tank operated by mechanism carried by the carriage, means carried by the carriage and cooperating with the tank to stop the carriage over each particular group of bottles, means interconnecting the means for stopping the carriage and the valve operating mechanism adapted to release the carriage Specification of Letters Patent.

Application filed July 28, 1909.

description which follows.

()f the drawings accompanying this de scription Figure 1 is a side elevation of my apparatus. Fig. 2 is an end elevation of the same. F ig. 3 is a perspective view looking at the underneath side of the carriage and showing the connections of the valve operating mechanism. Fig. 4 is a perspective view with the tank removed from the carriage, and Fig. 5 is a view of the tank as removed.

Referring to these drawings, 1 is a table which may be of wood covered with metal, or of slate. This table is provided with a rim 2 adapted to prevent liquid spilling from the table, and a drainage duct 3 is provided at one end to properly take care of liquid which may be spilled upon the table. The rim 2 in addition to the function just mentioned also serves the additiona-l purpose for positioning the bottles with respect to the filling devices, as will more clearly appear hereafter.

Mounted at each end of the table 1 is a standard 4, and extending between these standards are two track rails 5 and 6. One of these track rails 5 is provided with notches 7 a certain distance apart, while the other of these track rails 6 is provided with notches 8 at a less distance apart. The ends 9 of each rail are upturned to form a stop for the carriage 10 mounted thereon. while the ends 11 are extended a certain distance beyond the table.

The carriage 10 comprises a body portion provided with four wheels 12, two on each side. A tank 18 provided with a row of valves 14 is supported on the carriage. It will be noted that the bottom of the tank fits over the carriage body, the side and end walls of the tank depending around the sides of the carriage body and acting to hold the tank in position upon the carriage.

Each valve 14: of the tank is provided with an operating lever 15, and this operating lever is connected to the operating mechanism on the carriage. This operating mechanism comprises a transverse shaft 16 n'io-unted in journals 17 on the carriage, and provided with a series of adjustable arms 18 connected by links 19, one with each valve operating lever 15. The links jointed to the UPEL'ZLtlHg lovers of the valves and to the adjacent arms constitute an extensible connection. The tank may thus be moved a limited distance with respect to the carrier without breaking the connections. A set screw 20 passing through the arms 18 and bearing on the shaft 16 is a means for adjusting the arms about the shaft. The valves 14 may in this manner be adjusted so that. they will. each feed to the bottles beneath the carriage the same amount of liquid in a given time irrespective of the slight variations in the openings of the valves and of the variation in depth of the liquid in the tank due to irregularities in the tank or to the tilting of the tank in one direction or the other. A suitable handle or operating lever 21 serves to turn the shaft 16 to operate the valves.

Depending from the body of the carriage are lugs 22 to which are pivoted the detents adapted to engage the notches on the rails 5 and 6. These detents are held against the rail and in the notches by springs 24 drawing them upward toward the body of the carriage. A transverse shaft 25 is located adjacent the detents 23 and provided with cams 26 having a definite angular re lation with respect to each other and bearing upon the detents 23. A handle 27 is provided on the end of the shaft 24 whereby the shaft may be turned, the cams acting to cause the detents 23 to engage the rails one at one time and one at another time.

An interconnection is provided between the valve operating mechanism and the stops or detents 23. This consists of two fingers 28 and 29 engaging pins 30 on the detents 23. These fingers 29 are provided with knuckle joints 31, the ends of the fingers being spring pressed in such a manner that when the shaft 16 is oscillated by the. handle 21 in a direction to close the valves, that is, to the rig'at as shown, the fingers operate to remove the detents from the notches in the rails, and when operated in the reverse direction to open the valves, the end of the finger moves about its pivot at the knuckle joint 31 and does not move the detents.

Mounted on the standard 1 at one end of the track is a pulley 32 over which runs a cord connected to the carriage at one end, and at its other end to a weight 38 of such a size as will act to draw the carriage with the full tank along the track at a moderate rate.

In using my apparatus, the operation is as follows: The tank being full of milk the bottles to be filled are placed on the table andpushed up into contact with the rim surrounding the table into groups as shown,

the position of the rim on the table determining the position of the bottles with re spect to the track carried by the standards 4t. The carriage is then moved by hand to the position shown in Fig. 1 where the carriage rests against: the stops at the ends 9 of the rails, and in this position the carriage is held by detent 23 engaging one of the notches 7 in rail 5. The lever 16 is then turned to the left to open the valves. The bottles in the first row are thus filled, and when they are full the lever 23 is turned to the right to close the valves. In turning to the right just as the valves are closed, the fingers 28 strike the pins 30 on the detents 23 and remove the detent from the notch 7 in the rail Immediately the weight 33 pulls the carriage forward, it is to be noted that the finger 28 moves beyond the pin 30 in the full closed position of the valve, and the detent 23 therefore comes into play to stop the carriage when it has moved through the distance between two adjacent notches. The carriage is thus stopped over the next row of bottles. The valves it may then be opened thus filling that row of bottles. In the opening operation of the valves, the tin gers 28 are ratcheted past the pins 30 without moving them, and the ends of the fingers are moved by the spring at the knuckle joint into position to again release the detent upon the next closing operation of the valves. In this manner the entire number of bottles on the table may be filled.

The extensions of the rails 5 and 6 may be used to run the carriage out so that the valves 14 from the tank may be positioned over the last row of bottles on the table. If the track were not extended it would in some cases be impossible to fill a row of hottles placed at the extreme end of the table, and thus this valuable space might be lost.

It may be that it is desired to fill a number of bottles of a size different from the size first filled. In that case the shaft 24 is turned by lever 27 until one of the cams 26 operates to move the detent 23 cooperating with rail 5 away'from the rail and to allow detent 23 cooperating with rail 6 to be moved into contact with rail 6. The operation of filling these bottles of different size may thereafter be gone through with in a manner entirely similar to the operation of filling the bottles first filled, the finger 29 on the side next rail 6 coming into play to release the detent 23 on that side and cause the forward movement of the carriage as in the first instance.

In order to facilitate the cleaning of the tank, I have made the same removable, as can readily be seen from the drawings, the links 19 being disconnectible from the levers 15 operating the valves 14. This is clearly shown in Figs. 4 and 5. From Fig. 5 it will be seen that the valves do not protrude inside the tank but communicate with the tank at the very bottom, the bottom being entirely smooth so that sharp corners and inturned edges are avoided and the tank may be most readily cleaned. The removal of the tank is a most important feature, as it adl'nits taking the tank off and properly scalding it or otherwise sterilizing and cleaning it at certain periods. It is also to be observed that I have made all. parts adjustable so that the operation of the apparatus may be made as smooth and as well timed as possible. Not only are the arms 19 on the shaft 16 made adjustable, but the fingers 28 and 29 carr' d by that shaft are made adjustable about the shaft, as are also the cams 26 carried by the shaft 24L.

It will thus be seen that l have produced an apparatus which is simple in operation, cheap to manufacture, and at the same time is most adaptable to the service it is required to perform, and is most durable and eflicient.

While I have described in this application for Letters Patent the bet form of my invention now known to me, it is of course apparent that many changes may be made in the details without departing from the generic spirit of the invention.
