BOTTLE-FILLING MACHINE.

SPECIFICATION forming' part of Letters Patent No. 732,065, dated une 30, 1903. Application lcd November l, 1902. Serial No. 129,774. (No model.)

To all whom it may concern? Be it known that I, NICHOLAS GLAB, a citizen of the United States, residing atDubuque, in the county of Dubuque and State of Iowa,

have invented certain new and useful Im'- provements in Bottle-Filling Machines, of which the following is a specification.

This invention relates to bottle-filling machines, and has for its object to provide a lo simple and automatically-operating machine for rapidly filling bottles with liquid.

The invention also has in view to provide a machine of this character with valve mechanism of novel and improved construction I5 which will prevent waste of liquid and with means for permitting the escape of air displaced by the liquid as the bottle is being lilled.

The invention has other objects in View, zo which will fully appear hereinafter in the detailed description hereof and in the claims. In the accompanying drawings, Figure 1 is a central sectional View of a machine embodying my invention, two filling-tubes and z5 valves only being shown to avoid confusion. Fig. 2 is a sectional view on the line 2 2 of Fig. l, showing the openings in the tank for receiving the valve mechanisms and some of the valves in place. Fig. 3 is a top plan view 3o of the cam. Fig. 4 is a bottom plan view of the bearing-hanger for the actuating-levers. Fig. 5 is a detail view. Fig. 6 is an enlarged top plan view of one of the valve mechanisms. Figs. 7 and 8 are sectional views on 35 the lines 7 7 and 8 8, respectively, of Fig. 6. Fig. 9 is a bottom plan View on the line 9 9 of Fig. 7. Fig. 10 is a detail view of the valvedisk for the air-vent.

Like numerals of reference indicate corre- 4o spending parts in the several figures of the drawings, and referring thereto, 12 is a base of suitable character, and 13 is a driving-shaft journaled in bearings 14 and carrying the belt-pulleys 15 and a worm 16, `which is arranged to mesh with the worm-gear 17 on the vertical driven shaft 18. A plate 19 is fastened on the driven shaft above the base and carries at its periphery a number of arms 20, each of which is bored to receive and guide 5o the stein 2l of a bottle-rest 22. The bottle rest is provided 011 its under side with a socket 23 to receive the upper end of the stem, and a spring 24 is arranged in said socket above the stem to permit the rest to yield, and thus providefor variations in the height of the bottles. The bottle-restvis thrust upward by means of a crank-lever, which is preferably in the form ofvan elbow and has its long arm 25 connected by a link 26 with the lower end of the stem and its short arin 27 provided 6o with an antifriction-roller 23, arranged to travel around a cam 29, rigid with the base and preferably shaped like a saucer, Fig. 3. The actuatingllever is carried by a support 30, which is rigid with the driven shaft and is preferably made integral with the :guide carrying plate 19. This supportis provided at the bottom, Fig. 4, with a slot 3l to receive the actuating-lever and bearings 32 forthe stub-axles 33 of said lever. These bearings 7o are formed in the construction illustrated in the drawings by cutting out the Asupport on the under side, so that the axles of the lever may be slipped upward into place from below and there secured by blocks 34.

The machine may be constructed to accommodate atV one time any number of bottles, and the construction illustrated in the drawings is made to receive twenty-four bottles; but in Fig. l I have for clearer illustration 8o shown but two sets of the iilling mechanism, one bottle being filled and the otheribottle filled and ready to be removed or empty and placed on the rest, as the case may be.

A tank 35 is mounted on the upper end of 85 the driven shaft and travels therewith. This tank is provided with a removable cover 36, which is secured in place by means of thumbscrews 37, so that the tank can befmade practically air-tight. A feed-pipe 3S is arranged 9o iti a stuffing-box 39 in the cover of the tank, and this feed-pipe is connected to a' source of supply and discharges into a curved spoilt 40, which isfrigidly secured within the tank. To control and regulate the supply of liquid in thentank, I provide a float 4l and a valve 42, so arranged that when the liquid has reached a predetermined level in the tank the valve 42 will be closed by the Iioat, and the subsequent increase of pressure within the roo tank will sooner or later, depending upon the pressure at the supply, stop the flow of liquid into .the tank.

Referring particularly to Sheet 3 of the drawings, the valve mechanism comprises a body 43, which is screwed into an opening 44, Fig. 2, in the bottom of the tank and is provided with a central bore 45, into the lower end of which the filling-tube 46 is screwed. On the upper face of the body 43 and around the opening 45 is a rubber gasket 47, which forms a seat for the valve 48, and this Valve is fastened on the rods 49, which also carry at the lower end the head 50. A spring 5l is arranged on -each of the rods 49 and bears at its lower end against the head 50 and at its vupper end against a plug 52, which works in an opening 53 in the head and against the packing 54. The springs normally hold the Valve closed, and at the same time they press the plugs tightly against the packing, and thus prevent the escape of liquid from the tank through the openings in which the rods work. The head 50 is provided with a central bore 55 to receive the filling-tube 46, and it has a rubber gasket 56 on its upper face and a seat 57 onits lower face to receive the mouth ofthe bottle, the outer face 58 of this seat converging inwardly, as shown in Fig. 7, to provide an effective closure with the bottle. The parts are constructed and arranged so that in their normal position when the valve is closed the head 50 will be held below the body 43; but when the bottle is carried upward into position against the seat 58 as shown at the left of Fig. l, the head, and with it the connecting-rods and valve, will be forced upward to unseat the valve, and thus permit the liquid in the tank to iiow down through the iilling-tube and into the bottle. The valve remains open until the actuating-lever reaches the cutout portion of the cam, whereupon the bottle and its supporting mechanism descend, and the springs 5l simultaneously close the valve.

In order that the air mayescape from the bottle while it is being lled, I provide a vent which comprises a passage 59 through the body, which opens at its lower end in the space between the body and head 50, inclosed by the gasket 56 when the filling-valve is open, and at the top in a chamber 60. This chamber contains a valve of suitable character, which may consist of a loose disk 6l, Fig. l0, provided with notches 62 on its periphery and grooves 63 on its upper face and held vin the chamber by a hollow screw-plug 64, to which is connected a pipe 65 to discharge the air above theliquid-level in the tank. When the bottle has been clamped in place and the liquid begins to flow therein, the air will be forced out and up around the outside of the filling-tube into the space between the head and body inclosed by the gasket 56 and out through the passage 59 into the chamber 60, where the pressure of air will raise the valve 6l, so that the air can flowout through the notchesand grooves in the valve-disk and the tube 65 into the tank. Just as soon as the pressure of the air is insufficient to raise the valve 6l it will drop hack and close the passage 59, so as to raise the pressure in the tank. I provide grooves 66 in the wall of the opening 55 in the head to enable the air to pass up through the head and to the passage 59.

It will of course be understood that for each bottle on the machine there is an independent mechanism for raising the bottle and an independent valve mechanism, and therefore a machine can be constructed to accommodate at one time as many bottles y as may be desired. The cam is preferably timed so that the bottle will descend immediately or at least shortly after it is filled', and thus give the operator plenty of time to remove the bottles and insert new ones in place. This arrangementwill also permit the operator to remove several filled bottles at a time, or if the machine is traveling at a comparatively high rate of speed one boy may in sert the bottles while another boy removes them. As the bottle is tightly clamped against the head 50, so as to prevent the escape of liquid, it does vnot matter particularly how long the filling-valve remains open, and

therefore the machine may be constructed to accommodate a large number of bottles at the same time and operate rapidly, so that the lilling operation may be conducted at considerable speed.

My invention may be embodied in machines which differ more or less in construction from the one illustrated in the drawings and heretofore described, but without departing from the essential features and principles, and I would, therefore, have it understood that I reserve the right to make all changes which may be fairly considered to come within the purview of the invention.

The machine operates automatically, and the bottles may be inserted and removed by unskilled boys. The construction is such that no loss of liquid will occur if the operator fails to insert a bottle on each filling-tube, as the valve is not opened until the bottle is clamped in place, nor will the liquid which remains in the tube escape when the bottle is removed by reason of the pressure of air at the lower end of the tube and the fact that the filling-valve closes the upper end thereof. I prefer to contract the lower end of the lling-tube, as shown in Fig. 1. The construction is preferably such that the operator will of necessity arrange the mouth of the bottle on the lower end ofthe filling-tube to prevent the bottle from slipping off and form a guide therefor when the bottle is elevated to insure its being seated properly against the head.
