SAMUEL B. SMALLWOOD, OF LONG ISLAND CITY, NEW YORK.

- BOTTLE-FILLING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 523,014, dated July 17, 1894. Application filed March 15, 1893. Renewed February 8, 1894- Serial No. 499,539- (No model.)

To al l whom it may concern." i Be it known that I, SAMUEL B. SMALLWOOD,

a citizen of the United States, residing at Astoria, Long Island City, in the county of Queens and State of New York, have invented certain new and useful Improvements in Bottle-Filllng Apparatus; and I do hereby declare the following to be a full, clear, and exact descriptlon of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to improvements in bottle filling apparatus of the class shown and described in my former applicatrons, filed January 13, 1893, and May 13, 1893, and bearing Serial Nos. 458,282 and. 474,088,

respectively, and the object of the present invention is to provide a more simple and compact apparatus for this purpose than that shown in the applications referred to.

With these ends in View myinvention consists in the peculiar construction and arrangement of parts as will be hereinafter fully pointed out and claimed.

In the accompanying drawings-Figure l is a top plan view of a portion of the apparatus. Fig. 2 is a vertical sectional view on the line 2-2 of Fig. 1. Fig. 3 is an enlarged sectional View through one of the filling tubes or faucots and its attached bottle guide. Fig. 4 is an enlarged detail sectional view showing one of the filling tubes in position in a bottle; and

Fig. 5 is a transverse sectional view on the which is mounted on a suitable support A and connected, by means of a pipe or tube, B, with a cask or other source of liquid supply. The tank and support are not shown in the present case as they form no part of this invention,andas they and the connection between the cask and tank A are fully shown in my prior applications hereinbefore referred to.

The inner ends of radially extending supply pipes O are screwed into internally threaded apertures in the side walls of the tank Aand these supply pipes, of which there are preferably four as shown inthe drawings, communicate at their outer ends with the interior of a receptacle or filling ring, D, which is arranged concentric with the tank A.

The filling ring D, which is supported by the radially extending supply pipes C, is interiorly divided into two independent compartments or chambers, E, E, by means of a central horizontal partition D. The outer ends of the radially extending supply pipes enter the lower compartment or chamber E of the filling ring D and connect said chamber with the central tank A which, as hereinbefore described, is connected with a suitable source of liquid supply. The upper chamber E of the filling ring is connected with thesource of supply of the apparatus, above the liquid therein, by a pipe or tube F.

The filling ring is provided at regular intervals with depending filling tubes G which communicate at their upper ends with theliquid chamber E of said ring. The upper ends of the filling tubes are rigidly attached to the filling ring, being preferably screwed into intern ally threaded openings therein, and centrally within each filling tube is arranged an air tube H which extends through the filling tube and the upper end of said air tube extends through the horizontal partition D within the filling ring and communicates with the upper air chamber E therein. The air tubes H extend below the lower ends of their respective filling tubes and at its lower end each of said air tubes is provided with an enlarged tapered or conical or head piece H. In the head H is formed a horizontally extending passage h which opens at its outer end through one side of said head piece and communicates atits inner end with the lower end of the air tube H.

d A sleeve K is fitted looselyaround each filling tube and the lower end of said sleeve,

when the apparatus is not in use, rests on a 7 packing ring h fitted in an annular groove .tormed in the head H of the air tube H.

In the upper end of the sleeve K is formed a suitable stufling box adapted to be filled with any desired packing material, and thereby form a tight joint between said sleeve and the filling tube about which it is packed.

An annular, laterally projecting flange, L, is formedintegralwith or rigidlyattached to each sleeve K, nearits upper end and to said flange, L, are rigidly attached the upper ends of depending supporting rods M, to the lower ends to fill a bottle, the neck thereof is'passed through the central tapering passage in the guide N carried by any one of the filling tubes and the upper end of the bottle forced into the socket, p, in the elastic pad P. The bottle to be filled is thus hermetically sealed. By pushing upwardly on the bottle the sleeve K and parts attached thereto will be moved vertically a short distance, compressing the coiled spring 0 and uncovering the lower end of the filling tube and the outer end of the laterally extending passage, h, in the head H of the air tube H. As soon as the lower end of the filling tube is uncovered by the vertical movement of its sleeve K a portion of the liquid which has passed from the source of supply to the lower compartment or chamberof the filling ring D will pass into and fill thev bottle. The air forced out of the bottle by the entrance of the liquid thereto will pass through the air tube Hinto the upper compartment of the filling ring, and thence, through the pipe or tube F, to the source of liquid supply above the liquid therein. The stuffing box at the upper end of the sleeveK forms an air tight joint between said sleeve and the filling tube and it is therefore impossible for any air to enter the bottle while the same is being filled. The bottle and filling tube being hermetically sealed the bottle will only be filled to a level with the lower end of the air tube II. When the bottle is filled and removed the parts are returned to the positions shown in Figs. 2 and 3 by the action of the spring 0, and further escape of the liquid prevented.

Among the advantages of my. improve: ments as hereinbefore described, may be mentioned' the following: By having the filling tube cut off square and the entire area, less the small amount of space occupied by the central air tube, opening into the bottle, thev latter can be filled in about one half of the time required to fill the same with apparatus in which the liquid escapes through a lateral outlet in a filling tube.

Another advantage obtained by myinvention is that by employing the filling ring, I do away with the necessity for having a separate supply and air tube for each filling tube and thereby materially reduce the weight of the apparatus and render the same much simpler of construction. V

I am aware that changes in the form and proportion of parts and details of construction of the devices herein shown and described as an embodiment of my invention can be madewithout departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the right to make such changes and alterations as fairly fall within the scope of the same. For example,instead of having the air pipe F extend for a portion of its length *througlrthe liquid supply pipe, as shown in the present case, I may arrange said tube wholly without the liquid supply pipe.

Having thus fully described my invention,

what'I claim as new, and desire to secure by- Letters Patent, is-

1. In an apparatus of the character described, the combination with a source of supa filling ring arranged concentricwith a supply pipe and having its interior-divided into two independent compartments one of which is connected by liquid supply pipes with the source of supply, the other compartment of said ring being connected with the source of supply above the liquid therein, and a filling tube communicating with the liquid compartment of the filling ring and having an air tube which communicates with the other compartment of said ring, substantially as described...

' 3. In an apparatus of the class described, the combination with a source of supply, of a tank, A, connected withthe sourceof supply and provided with a series of radiallyprojecting supply pipes which support and communicate with one compartment-of a filling ring which hasits interior divided'into two independent compartments, connections between the other compartment of the filling ring and the source of supply abovethe liq: uidtherein, and a .filling'tube which communicates with the liquid compartment in the filling ring and has an air tube which communicates with the other compartment of said ring, substantially as described.
