invention relatesto improvements in bottle filler machines and in particular to the filler valves of such machines.

There are several bottle filler machines which have been patented and are on the market, which embody filler valves of the general mechanical structure of that embodied in my invention. For this reason it has not been thought necessary to illustrate and describe such machines in detail, as their general operation is well understood in the art. Generally speaking, in operation, a series of bottles are positioned in predetermined positions below the respective filler tubes of the machine. By automatic operation of the machine, a filler tube is lowered into the mouth of the bottle, whereupon fluid passes through the filler tube, and on opening of the valve flows into the bottle.

, When a predetermined amount of fluid has passed into the bottle, the valve automatically closes the mouth of the tube and the tube is withdrawn from the bottle mouth. In most such machines of the character generally described, the filler tubes during the filling operation revolve at a high rate of speed. Frequently the filler tubes become bent and on revolution contact the mouths of the bottles into which they are inserted, thereby gradually reaming out the bottle mouths and thus causing small particles of ground glass to enter the bottles, and also finally, producing destruction of the bottles, if the benttubes are not removed.

Heretofore, filler valves for such machines have universally been made of metal, necessitating certain structural features by reason of their metal.

composition, and in use showing many disadvantages, among these being: corroding of the valve tube and also the valve proper, thereby resulting in destruction of the tube and valve proper and also small particles of corroded metal washing into the bottles being filled; also wearing by corrosion of the valve seat thereby producing imperfect valve action; in machine operation, the tubes become bent and in revolution gradually ream out the bottle necks and finally destroy the bottles, as previously described. It might also be mentioned that in the use of metal tubes it is impossible to ascertain the cleanliness of each tube, through which the liquid flows without detaching each tube from the machine andmaking a minute inspection of the tubes interior, all of which requires labor and time in performance, as well as a stopping of the filling machine while this inspection is being made.

To overcome the difficulties encountered in the use of filler valves of metal, I have invented a filler "valve? and? preferably" a plastic of} coal; water" aind' air composition or similar compounds, one name for which is lucite. A tube of such composition is not subject to corrosion, isnon-acidizing, is practically impervious to wear, is pliable but not breakable and will not lose its original shape, and is translucent thereby eliminating all of the objectionable features previously described in metal filler valves. By reason of the composition qualities of the material embodied inmy invention, I have also been able to incorporate structural features heretofore impractical of application in the old type of filler valves.

For the purpose of disclosing my invention I have illustrated one embodiment thereof in the accompanying drawing, in which:

Figure 1 is a longitudinal view of a filler valve embodying my invention; and

Figure 2 is a cross-sectional view thereof.

Referring now to the drawing in detail in which shaped valve at the lower end of the filler tube l which is of the same composition as the tube I. The upper end of the pear shaped valve-2 is provided with a collar 3. The collar 3 is adapted to fit snugly about the lower periphery 4 of the tube I, as illustrated in the drawing.

The collar 3 of the valve 2 is provided with a number of discharge openings 5 in the side thereof, through which, when the valve 2 is in the lowered position shown by the dotted line 6, 1 and 8, the fluid from the'tube l discharges.

The {valve 2 is mounted on the lower end of a piston rod 9, thepiston rod 9 being a component part of the valv 2, and not a separate unit attached thereto. The piston rod 9 extends upward from the base l0 of the valve 2 through the supply tube I and extends beyond the top thereof, as illustrated in the drawing. f

The upper end of the rod 9 is threaded at H], and is' attached to the valve operating mechanism, which is not illustrated. As this general type of valv and filler tube is generally employed in most bottle filling machines nowin use, aspreviously menti0ned,'it has not beenthought necessary to her illustrate the mechanism which operates the pistonrod 9, as these illustrations are fully given in the several patents of nonbreakable plastic composition,

beneath a filler valve, suitable mechanism of the bottle filling machine causes fluid to flow into the tube I, immediately followingwhich the piston rod 9 lowers the valve 2 from the position shown in the drawing to the position of the dotted lines 6, 1 and 8 in Figure 2, thereby opening the valve and permitting the fluid to flow through the discharge openings 5-5 into the bottle into which the valv 2 has been inserted.

The inner surface of the collar 3 has been machined to iit'snu'gly at all'times about the lower periphery 4 of the tube I. When the valve 2 is in closed position as shown in the illustrations, there exists a ground joint between the lower end of the tube 2a.
