CHARLES DE LUKACSEVICS AND CLAIR J'. TERRILL, OF WEST NUT'LEY, NEW JERSEY.

SIPHON-HEAI).

Specification of Letters Patent.

Patented May 2, 1916..

Application filed August 30, 1915. Serial No. 48,045.

To all whom/it may concern:

Be it known that we, CHARLES on Lunacsnvros and CLAIR J. TERRILL, citizens of the United States, residing at West Nutley, in the county of Essex and State of New Jersey, have invented new and useful Improvements in Siphon-Heads, of which the follow-. ing is a specification.

The present invention relates to siphon heads and is more particularly concerned with improvements in the construction of the siphon head shown and described in the application fierial No. 2 1,116, filed April 26, 1915, by Charles de Lukacsevics.

It is the mainobject of the invention to produce a siphon head with a more durable connection between its connecting parts and more durable bearings provided for its operating parts.

It is also an object of the invention to produce a siphon head with few parts which are easy to assemble and which is inexpensive to manufacture and efficient in operation.

With the above objects in view, the invention consists in a certain novel construction,

' combination and arrangement of parts hereinafter more fully described and finally pointed out in the appended claims.

In the drawings :Figure 1 is a side elevation of the siphon head applied to a bottle or jar and having a portion thereof broken away to illustrate its interior construction and operation of operating parts; Fig. 2 is a plan view of the bushing used inthe con struction of the siphon head; and Fig. 3 is a side view of the bushing shown in Fig. 2 and having a portion of the same broken away for the sake of illustrating its construction.

Like characters denote similar like parts throughout the specification and drawings.

Referring particularly to the drawings, A denotes the siphon head attached or suitably secured to the neck of the bottle B.

1 denotes the body portion of the siphon head provided with a longitudinal bore 2 through which the valve stem 3 extends and is actuated'by the lever 1. The upper end of the body portion 1 is formed with a clownwardly extending slot 5 extending through the side of the body portion to the bore 2. The wall of the bore is also formed diametrically opposite said slot with a recess or cavity 6. An operating lever 11 is provided for controlling the operation of the valve stem 3 and has a rounded or spherical end 7 extending through the slot 4 and normally resting in the recess 6. The upper end of the valve stem 3 extends through an aperture 8 formed in said lever adjacent its spherical end and thenuts 9 are threaded on the upper'end of the valve stem for retaining the lever in extended position through said aperture. Pivotal bearing members 10 and 11 are provided on the lever on opposite sides of the aperture 8 and engage with the nut 9 and shoulder 12, respectively, for permitting a pivotal movement of the lever with respect to the valve stem. A coil spring 13 surrounds the valve stem 3 below the lever et and exerts tension upon the lever, normally holding the valve stem 3 and lever 1 in their uppermost positions, as shown in Fig. 1. The above construction is set forth in said above application, Serial No. 2 1,116, and is old, the feature of the present invention residing in the provision of a bushing C secured in the bore 2 of the body portion 1 of the siphon head and providing a more durable threaded connection for securing the cap 1 1 to the body portion and providing a more durable bearing for the spherical end 7 of the lever 4 resting in the cavity 6 of the siphon head.

The body portion of the siphon head A is preferably constructed of material such as hard rubber, bakelite, condensite, hiheet, or the like, and the introduction of the metallic bushing C reinforces the body portion of the siphon head in which the operating parts are located as well as providing a more durable threaded connection at its upper end for the cap 14. The bushing C is of tubular formation and has its inner diameter coinciding with the diameter of the bore 2 of the siphon head. The lower half portion of the bushing is provided with a plurality of spaced and concentric annular flanges 15 on its outer periphery and has its upper half portion threaded, as indicated at 16. A slot 17 is provided in the bushing and extends longitudinally thereof and is adapted to coincide and register with the slot 5 formed in the body portion 1 when the bushing is molded or secured in position in a completed siphon head. Diametrically opposite the slot 17 of the bushing the latter is formed with an aperture 18 through which the spherical end 7 of the operating lever extends and against the walls of which the same bears during the rocking operation of the lever.

The bushing C is placed or positioned in the die, for forming the siphon head A, in such a manner that when said head is formed the bushing is embedded therein, as shown in Fig. l of the drawings. The flanges 15 provide suitable grooves 19 therebetween which prevent the bushing from being withdrawn from'the bore 2 of the siphon head after the latter has been molded. The threaded end of the bushing 0 extends beyond'the upper extremity of the body portion 1 to provide suitable means for connecting the cap 14 of the siphon head to the body portion. The cap 14 is provided on its inner orunder side with a guide-way 20 adapted to extend downwardly into the bore 2 and to receive the upper end of the valve stem 3 carrying the nuts or bearings 9, whereby the movement of the valve stem will be guided. Itwill also be noted that when the cap 14: is secured in position, the operating parts of the siphon head are secured in operative position against removal therefrom and that when the cap 1a is removed from the body portion 1, the nuts 9 maybe threaded from the valve stem and the operating lever 4 removed from the siphon head.

Having thus described our invention, it is believed that a full and clear understanding of the same may be had, however, it

' is to be understood thatcertain changes as to the exact construction, combination and arrangement of parts may be resorted to that fall within the legitimate scopeof the appended claims.

' Having fully described our invention, we claim- 1. In a' siphon head, a non-metallic body portion formed with an internal bore therein and an opening communicating with said bore, a metallic bushing secured in said bore and formed with an opening registering with said first-mentioned opening of the body portiointhe upper end of said bushing extending beyond said body portion and being threaded, valve operating means in said bore, an operating lever having one end extended through said opening in the body and pivotallysecuredtherein, said lever being adapted to actuate said valve operating means, and a cap removably threaded on said bushing and adapted to engage with said valve operating means for retaining the whole organization in operative position.

2. In a siphon head, a non-metallic body portion formed with an internal bore therein and an opening communicating with said bore, a metallic bushing secured in said bore and having one end threaded and extending beyond the upper end of said body portion, said bushing being formed with an opening adapted to register with the opening formed in said body portion, said bushing being formed with a recess therein diametrically opposite the opening therein and in said body portion, valve operating means in said bore, a lever having one end extendloosely retained in said recess, said lever being adapted to control the operation of said valve operating means, and a cap adapted to be threaded upon the extended end of said bushing and to engage with said valve operating means to retain the whole organization in operative position.

3. A siphon head molded of non-metallic material and having a bore extending therethrough, a metallic bushing having an irregular surface and molded in said head with the bore of the latter extending therethrough, one end of said bushing being threaded and extending beyond one end of the head, said bushing and head being with said bore and with a recess diametrically opposite said opening, valve operating means in said bore, an operating lever having one end extending into said opening and pivotally retained in said reces's, said lever controlling said valve operating means, and a cap for said head of non-metallic material adapted to be threaded upon the threaded end of said bushing whereby the whole organization is held in operative position.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.

CHARLES DE LUKACSEVICS.
