SIPHON-HEAD.

Specification of Letters Patent.

Patented hiar. 7, 1916.

Application filed October 3, 1912. Serial No. 723,696.

To all whom it may concern Be it known that I, JOHN A. SoHUL'rz, Jr., a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Siphon-Heads, of which the following is a specification, reference being had therein to the accompanying drawings, which form a part thereof.

My invention relates to siphon heads, and more particularly to a type of siphon head which while being non-corrosive or capable of resisting the action of the gaseous and fluid contents of a bottle, will contain substantially no tin or other metal having value as old metal.

The main object of the invention is to provide a siphon head .wherein' the head casing will be composed of two parts, and that portion ofthe head through which the fluid flows will be detachable from said head casing and adapted to be secured in place by the application of the head to a bottle, and will at the same time lock the two parts of the head casing in a manner to secure the proper permanent relation of these parts one to the other.

A further object is .to provide a'siphon head wherein the casing will be composed of a non-frangible metal havinggreat tensile strength, such as iron, to avoid a stripping of the threads, and wherein the detachable spout portion will be composed of non-metallic material capable of being worked by tools so as to permit the formation or repair of a valve seat thereon.

A still further object is to provide a siphon head of the character herein .described, which, while being composed of a plurality of independent detachable portions, will when mounted upon a bottle have such portions so united as to form a practically integral waterproof and gasproof structure. v

The invention consists in the novel features of construction and combination of parts hereinafter set forth and described,

and more particularly pointed out in the claims hereto appended.

Referring to the drawings :-Figure 1 is a side elevation of a siphon head embodying my invention, attached to a bottle; Fig. 2 is a vertical section thereof; Fig. 3 is a view of the upper portion of the head casing; Fig. 4 is a detail view of the lower portion of the'head casing; and Fig. 5 is a detail view of the spout and valve seat portlon. v

Like letters refer to like parts throughout the several views.

In the embodiment of my invention shown in the drawings, I have shown at a a cored casing of nonfrangible material having great tensile strength, such as cast iron, the upper portion of this casing being reduced to form a spring chamber a, and the lower portion thereof being enlarged to form a valve seat block chamber a a shouldera being formed within said last named chamber adjacent to said first named chamber. Thelower rim of this casing a is provided with an outwardly presented flange b. In one side of, and toward the top of, this casing is formed a slotted way 0 for the lever handle, and in the wall of the spring chamber, opposite this slotted way, is a recess 03 adapted to form a fulcrum seat for said handle. The top of the casing is preferably made open, and provided with interior screw threads adapted to cooperate with the screw threads upon a closure cap 6 which may be, and preferably is, made of the same material as the casing.

Y Leading from the chamber a is an opening 7' opening downwardly through the flange .b, the upper portion of this opening being adapted to conform to the contour of the spout. WVith a round spout, the upper end of this opening willbe curved as shown in Fig. 3 of the drawings.

The lower portiong of the head casing is preferably composed of the same material as the portion a and is circular in form, and provided adjacent to the lower edge thereof with interior screw threads g adapted to cooperate with the split ring In commonly used for attaching the siphon head to. a bottle, indicated at i. The top of this portion g is provided with a circumferential, inwardly projectedflange y' adapted to bear upon the-flange b .ofthe head portion 0;. Through one wall of said portion 9 adja cent to the top thereof is an opening 9 adapted to register with the lower. portion of the opening 7 and confine the spout between these two p arts.

Seatedwithin the chamber a is a valve seat block k having connected therewith, preferably integrally, a spout is This spring spout is so formed-as to have a fairly close sliding fit with the opening 9 thus serving, when the head is assembled, to prevent the rotation of one of the parts a or is relative to the other. To permit the insertion of this block within the bi-part head casing I make it in the form of a truncated cone, the top dimension of which is the smaller. Seated between the top of the block A; and the shoulder a is a packing ring Z which serves to prevent the escape of any of the fluid contents of the bottle about the valve stem.

Extending vertically through the block it is a port and moving in this port is a pressed valve spindle m having an enlarged head m terminating adjacent to the slot 0 and recess 0?. Acting between the ring or gasket Z and this enlarged head is a spring m having a normal tendency to raise the spindle. Acting upon said enlarged head is an ordinary lever handle m moving in the slot 0 and having the inner end thereof seated within the recess d.

The upper face of the block is is recessed as shown atlc to insure the expansion of the gasket Z toward the valve stem m. Centrally of the lower face of the block it and extending about the lower face of the port 70 is a continuous circular valve seat n which projects to a considerable extent from the lower end of the block is. Encircling this valve seat is a channel 0 forming an annular shoulder 32 about the seat 12. adapted to engage the flange of the metallic siphon tube head (1. Adjacent to the spout lo I provide a segmental bead 7- adapted to fit the open space in the rim 7' at the opening 9 thus when'the device is assembled, presenting a substantially continuous bead within the section 5/ against which the gaskets which is used for sealing the entire valve block is, the siphon tube head q, and the section a, may bear in a manner to prevent the escape of water therefrom. Carried by the lower end of the stem m and seating on the Valve seat n is the customary valve block 6.

Preferably the valve block is and the spout is. are formed of non metallic material such as vulcanite, indurated fiber, or other similar material, which may be molded to form,

and yet be capable of being worked with tools. The materials named are substantially water, acid and gas proof, permitting the production of the entire head at a reasonable cost, and at the same time eliminating from the head any metal having value as old metal. If desired, tin may be used for the valve seat block and spout without departing from the spirit and scope of the invention, but I prefer to use the other materials. When I use the vlucanite or indurated fiber, I provide the top of the port 76 with a metallic bushing is in which the stem m moves.

The operation of my head when assembled is substantially like that of any other head of the ordinary type, as to the charging and discharging of the fluid contents of the bottle. In assembling the device, however, the bi-part construction of the head casing permits such a relative movement of parts as will facilitate the insertion of the valve seat block and spout, these parts, however, being so united when pressure is applied upon the part 9 by the split ring it, as to give such rigidity to the entire structure that it will to all intents and purposes, be a unitary structure when assembled upon the bottle. The gasketsis compressed upon the lip of the bottle 2' by the pressure exerted by the annular shoulder 9, upon the flange of the siphon tube head 9, the portion of the said gasket projecting beyond this flange being slightly compressed by the flange b and fitting 1" so as to seal the joint between the two sections a 9. As heretofore stated, the spout 7c having a close slidingfit with the openings 7 and 9 the parts a g are held in such relation to each other as to prevent any such movement of either part as would result in wear upon the gasket 8. The block 70 is made in the form of a truncated cone in order to afford suflicient clearance between the upper part of the block it and the wall of the chamber (E, in assembling the device.

WVhen mounting the head upon a bottle, the split ring 71 will exert a downward pull upon thepart g, and cause this part through the flange j thereon to. exert sufficient pressure upon the part a through the flange b thereon, to compress both gaskets Z and s and thus firmly seat the block it within the chamber a If by any chance there should be an imperfection in the annular shoulder 39, the gasket 8 will pack the flange b and bead r in a manner to prevent the escape of the fluid.

. Having described my invention, what I claim as new and desire to have protected by Letters Patent, is

1. A siphon head embodying therein a bipart head casing, the lower part of which has interior screw threads, an opening in the top thereof, a recess in one side wall thereof opening into said top opening and an inwardly projected flange about the opening in the top thereof excepting across said recess, and the upper of which parts has an open bottom, a reduced portion forming a spring chamber, an enlarged bottom portion forming a valve block chamber, aspout opening in the side wall thereof, and an outwardlv projected flange extending about the open bottom of said part excepting across said spout opening, said flange being adapted to engage the flange of said first named part whereby separation of said parts when assembled is prevented, said spout opening being adapted to register with the recess in said first named part, a valve block adapted to be seated in said valve block chamber, a spout carried by said block and adapted to project through and engage the sides of said spout opening and the recess in said parts respectively, said valve block having a bead thereon adjacent said spout whereby said bead and the flange about the bottom of said valve block chamber will form a substantially continuous rim adapted to engage a gasket, and a Valve mechanism.

2. In a siphon head the combination with a bi-part head casing, one of the parts of which has internal screw threads, an opening in the top thereof a recess in one side wall thereof opening into said top opening, and an inwardly projecting flange about the opening in the top thereof and the other part of which has an open bottom, a reduced Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

a spout integral with said block adapted to,

project through and engage the sides of the spout openings in both parts of the head, and a valve mechanism.

In witness whereof, I have hereunto affixed my signature, in the presence of two subscribing witnesses, this 16th day of September, 1912.
