Be it known that I, PHILIP Sr1TzENBnnG,a

citizen ofthe United States, and a resident of the boroughv of'Brooklyn, in the city of yNew York, ,county of Kings, and State of New f 'Yorin have` invented. certain new and useful `lirlprovements in Siphon-Heads, of ywhich the following is a speciiication, reference being had therein to the'accompanyingdrawings,

which form a part"k thereof. My inventionrelates .to sil more particularly to Athe valve'jmechanism l thereof. f

`As nowfcommonly made the head is 'cast with a dividing-partition just belowl the spout, [a valve-seat being subsequently turned and ,finished on the lower side of vsaid partition, it kbeing foundimpossible to cast this-seatsufciently'accurately to avoid the'necessityforA this fnishing'jproces's.'

The laborof lassembling is also materially increased by thenecessity for depressing the valve-spring in order to adjust the lever-handle controlling same.

packing may be inserted in the head-casting from the bottom, thus obviating the necessity for a removal of the top cap and facilitating the assembling of the device or its repair,

A still further object is to so construct and arrange the various .parts of said head' as to cause the act of attaching the head to. av bot-` tle to. packron .both sides of the valve-seat to -coninethe liquid discharged therethrough .55.v

ther object is to provide a Siphon-head which lmay .be inexpensively manufacturedv and the parts Sof whichmost-subjectto wear may be., replacedwithout materlal expense, such as 1s f incidental to forwarding bottles to the shop Yor factoryl n u. l 'The'inventlon consists, prlmarlly, in the combination, with a head-casting having an interior chambervopening"downwardly and a` -spoutcommunicatmg therewith and means wherebyjsaid head-casting maybe attached to v a bottle and? placed in communication-there with' through the siphon-tube, ofa valve-"seat Y blockseated in said chamber and separable downwardly ajface whereby it is heldin place through "said means and having a way -theref in whereby communication'is established be-y tween said tube and said spout, a valve-stem,` f'

r7 5jl a' normally closed valve controlled. thereby,

means whereby-said valve-stem may be actu f v ated,land packing for said block, and in such othernovel. features of construction and arrangement of parts as are hereinafter set forth anddescribed, and more particularly pointed out in the claimsheretoappended. v

Referring tothe drawings, Figure l is an elevation of a Siphon-head embodying my inl ventionl applied to the upper part of' an ordinary type of bottle.l Fig. 2 is a vertical sec- Fig. 3 is an elevation. of the valve mechanism detached fromthe head-cast# ing, and Fig. i is avertical section thereof.

, Like letters refer tolike partsthroughout the several views.

'In the'accompanying drawings, a indicates lthe upper part o'f an ordinary Siphon-bottle,

`a split screw-threaded ring adapted to en- A gage' the said lip a and coperate with scre'w- A threads in the interior of the lower part of the Siphon-head, as show n in the drawings. A f

glass tube c is suspended within the bottle by.

means ofa funnelshaped top c", attached thereto and having a iiange c2, between which andI the'top of the neck of the bottle is an annular gasket or packing-ring d.

The foregoing arrangement of parts is that now generally employed, and it is not my inlOO ids"

tention to claim such, this invention residing more particularly in the detailed construction of the Siphon-head alone or in combination with'the heretofore-described combination of partsl for attaching same or any other desired combination of parts serving the same purpose. v

The Siphon-head embodies a head-casting e, having therein a chamber adapted to receive the valve mechanism, the valve-seat block, and the means actuating the valve. Said headcasting in its preferred form presents within said chamber two substantially parallel annular shoulders e e2 of different diameters, a fulcrum e3 for the lever-handle f, and a way @4, in which said handle moves. This chamber opens downwardly and is closed at the top. A spout g, as ordinarily now employed, is carried by said head and communicates with the chamber therein. Preferably this head is cast in a single piece, the absence of a valveseat partition below the entrance to the spout permitting this. This production of the headcasting at a single operation is in the interest of economy; but it is apparent that, if desired, it may be made in several parts and subsequently assembled for use in connection with the other features of my invention.

The valve mechanism embodies a valve-seat block consisting of the base `it, the-lower face of which is provided with a channel forming a central valve-seat h and a rim if, both of which are downwardly projected, a body c' surmounting said base and fitting fairly snugly within that portion of the chamber within the head-casting below the shoulder e'. This body is of smaller diameter than the base, the upper face of which latter extends below the shoulder e2. The said body is surmounted by a gasket or packing-ring i', preferably of soft rubber, which packs the chamber above the said block. To permit the passage of water or other liquid through said blockto the spout, I provide a continuous way 2 therein and also a channel exterior to said body, as 3. A puppetvalve c bears against the valve-seat 7L', normally closing the way 2. This valve is provided with a packing 7c', preferably ofsoft rubber, and the metallic body thereof is provided with fins 762 or other means facilitating the assembling of the valve mechanism.

The valve-stem Z is attached to the valve c, preferablyby means whereby said valve is separable from said stem, as coperating screwthreads on said parts, thus admitting of the replacement of the valve-blockwhen worn. Said stem Z is mounted in a way in the upper part of the body@l of said block, the packingring i serving to also pack this stem. A head my, provided with a central top fiange m, surmounts said stem, the sides of said head tting and moving in the upper part of the chamber within said head-casting and serving as an upper seat for the valve-spring n, the other end of which spring is seated on a washer 0, resting upon the packing-ring 7l.

The handle f is provided with a recess adapted to engage the flange m and a protruding end adapted to rest upon the fulcrum e, the inner end thereof being fitted to the way e".

In assembling the device the spring n is slipped over the valve-stem l, the washer o, the gasket or packing-ring f/, and the valveseat block also being mounted on said stem. These parts when so assembled are held in a suitable keeper, and the valve c is then attached to the bottom of the stem by being screwed thereon to an extent to hold all these parts in relation to each other and so tension the spring a as to normally hold the said valve f against the seat L on the base la of the valveseat block, the channel forming said seat permitting an automatic adjustment of said valve to said seat to compensate for any wear on the saidseat or on the packing-ring It" to said valve. Thereupon the lever-handle f is inserted through the way e4 with its protruding end resting upon the fulcrum e, and the valve mechanism assembled as heretofore described is forced into the chamber in the head-casting e until the packing el engages the shoulder e2. Owing to the necessity for the packingring z" being a fairly-tightfit, some dificulty may be experienced in so forcing said valve mechanism to place; but this is largely avoided by slightly tapering said ring. When once placed, however, the friction between this ring and lche head-casting is sufficiently great to hold the valve mechanism in place while applying the entire head to the bottle.

Preparatory to attaching the head to the bottle the rubber packing-ring dis placed on the top of the bottle and the Siphon-tu be c is passed therethrough until the flange 020il the funnel-shaped top c' thereof rests upon said ring, thus suspending the said tube within the bottle in the proper position, or, if desired, the said ring may first be placed with relation to said flange c2. The split ring is then fitted below the lip a and the head-casting screwed to place thereon. As will readily appear from the showing of Fig. 2 of the drawings, the iianged top c' enters the channel about the valve-seat 71,', the rim bearing L* kupon the gasket or packing-ring (l and so expanding same as to pack the valve mechanism in a manner to permit the liquid under pressure to pass through the way 2 only. The valve ,7n projects into the funnel-shaped top c', wherein it is free to move to open said way 2. This same operation forces the valveseat block upward, so as to cause the shoulder e' to press against and expand the gasket or packing-ring z" in a manner to pack above said block and also about the valve-stem Z. It is apparent that, if desired, the shoulder @2 need not be perfectly fitted with relation to the base of the valve-seat block, the upper shoulder e being alone sucient to accomplish the desired result.

The tension of the spring a need not be heavy, as the function of this spring is merely t-o restore the valve 7c to its seat, the normal TOO I5 i -wisenishing said seat.v If wear do'esoccur The valve is openedby turn forces the valve-stem Z and the valve 7 downwardly againstthe tension of the spring n until the way 2 isv opened, whereupon water under pressure passes through said way tothe-spacev about the valve-seat block in the channel als andthe spout y.

By reason of the construction and arrangement of the valve-seat blockitmay be accumechanism replaced without the necessity for rately'cast without-the formation-of flaws-or yblow-holes in or about thevalve-seat, thus obviating -the necessity'for facing or otheranism maybe removed, newv partsjsubstituted for lthe worn parts, andthe renovated val-ve n machine-work thereon, v which Would-require theshi'pment of `the Siphon-head tothe shop i A or factory, and, 'furthermorafthis replace-L .1 z 5 ment of worn parts` may be accomplished'with- -v out weakening or damaging the head-casting through ,wear to minor and inexpensive partsinany way whatsoever, thus limiting the. loss which may readily`bereplacedt, 1

. 1- believe it to be broadlynew-1itja1sipt0ni head toprovidea valve-seat block separable from the head-casting,` andit is my` intention to claim suchlbroadly; f f

While in the accompanying drawings -have shown the various-parts as.v beingeylind'rical,

it is apparent that so long as the' valvemech`4` vanism 'conformsvto -the chamber withi'njthe head-casting in ,such particularsasto provide a suitable packing lthereof the'contouro'ffthese parts is immaterial.
