i whom is may cancer? he it known that we,Prr1LIr MUELLER and t SCMUERMANN, citizens of the States, and residents of Decatur,

State of Illinois, have in- .nd useful Improvements in our preferred manner of carryset forth in the folexaotdescription, particularly speciand i the invention is full, clear, and hating with claims he novelty. lnis invention relates to water distribulion, more especially to cocks and faucetsthat type which have reciprocating s; and ts object is to iniprove the conof the roller support infaucets of cha .cer where rollers are employed be- "idulating ways.

on is exemplified in the strucidescribed ahd is illustrated a self-closing basin cock, al-

be clear thatiit would be in any structure wherein the if the shank by its handle is inrcci 'n'ocate the stem to open the t is obvious that the latter need not hy'pressure and that other details Oi s ucture forth herein are not cs ial to the present invention which con- 3 mainly in a ring-shaped. spider with three or more inwardly projecting pins on.

wu'ah are mounted the rollers that travel on sl i l in dra.wings-l igure 1 is acentral vertica etion through a basin cock of one type wherein this invention can well be emto l the parts being shown at rest with me closed by pressure. Fig. 2 is a ilar section of the cap (dotted) and the and its disk depressed therein so as to the ways; and Fig. 3'is an en ed plan view of the spider with one in place, anotlierremoved,and the third in section. I

The cock body 1 has a spout 2 and a valve seat 3, and through the latter projects the stem 15 suitably guided so that it may move vertically. At its lower end the stem carries the valve 18 which is here shown as mounted on the top' of an inverted cupshaped shell 17. The latter fits rather closely "having a hollow shank e of the cock body and l inlet openings 15, and than the interior of the,

the upper end ot the plug is dished to produce a chamber 20 between it and the shell 17. The construction here shown is such that the pressure of water flowing tln'ough the inlets 15 and passing betweer shell into the chamber 20, will hold the valve tightly'closed against its scat fl as seen in Fig. l; and when it is desirecbto open the valve the stem l6 may be depressed by forces from the chamber 20 the water-that has accumulated therein and drives it outward in a direction opposed to the flow of the incoming waterwhich ob iously passes upward through the annular space around the shell. However, as above stated, we do not limit ourselves to the use of the present invention in avalve of this construction, but have illustrated the same one desirable type of th which it may be used to advangeeks wi taut v The upper end of the cock body is externally threaded. and screwed thereon is the cap (3 which isperforated at its apex for the passagcof the shank 8 which carries a removable. handle 10 as shown. Secure-d to the lower end of the shank and mounted for notation within'the cap is a disk 9, and the contiguous faces at the topiof this disk and within the top of the cap provided with I undulating ways 7 in each of which there should be at least three tracks or undulations. Between these ways are in ountcd roll- "and the position and proportion of when the valve is closed as seen in Fig; is in contact with the bottom of the disk 9 and the rollers lie in the depressions between the two tracks 'C mine now more phrticularly to the-pres cut invention, the rolldrs 12 are supported in place we ring-shapedspider ll of considerably less height tllflil\ljll6 diameter of an yroller and itself of less diameter thltn the interior of the cap. From this; spider three pins 11 project radially inw? 'd, and on these pins the rollers are journalilos shown. For this purpose the inner end of the bore through each roller is countersunk slightly as shown at 12 and the inner end of the pin.

is upset into said countersink as shown at 11. The outer ends of the rollers rounded off transversely on agreater curvature 1 the plug" and means to be described below, which actionl\ the ripper end of thest-em 16f ring as shown at 152 so that. they willv rotate their journals with the least possible friction against the ring. The length of the rollers and pins is such that they will not quite contact with the shank 8, and their diameter and the material of which they are composed are mlatters which I prefer to leave to the manufacturer, 4 Xperiment' has shown that the use of a ring-shaped spider in this connection will hold the rollers equally spaced at all times, whether the various tracks of the ways be accurately identical or not, and yet the "ciently to open the valve. the construction shown,

spider will not rub against the wall of the cap nor the inner ends of the rollers or pins of which actions take place rather s owly but it is obvious that the present invention.

" lifted 0a of the shank;

could be applied to a valve which was closed by a spring, and we contemplate the use of the same in any place where it would be of advantage.

The parts are disconnected as best illustrated in Fig. 2.- from the -cock body and'with it is removed the shank and its disk, its handle is then do: tached and the other parts drawn out of the cap, and finally the spider and rollers are It'may not inall cases be necessary to upset the inner ends of'the pins, but one advantage of doin so will appear at this time because thero lers cannot become accidentally from the spider.

The use of a r1ng-shaped spider eliminates the possibility that one or more of the rol ers shall leav'ethetrack, keeps them "equally" spaced an'd at all; times'in contact with the undulations and ready for" service, prevents them from working", radially outward and contacting with the; cap against which they might stick or into which they might wear I a groove. andf the upset inner ends of the First the capis unscrewed disconnected ends of said-pins being upset w thin said pins prevent the rollers from working inward and coming in contact with the shank.

What is claimed as new is:

1-. The combination with two memb ers lsgving opposed annular undulated ways, i for turining one-:member relatively to the other; of a series of cylindrical a d means rollers disposed between saidwayisi'a' ring Iers, an i shaped spider surrounding the ro pins projecting from the spider radially inward and on which said rollers arejour:

naled,'the outer ends of said rollersb being rounded ofi transversely on'a greater curvature than theinterior of said ring.

2. The combination with two members v having opposed annular undulatedv ways, a

1 shank on one projecting through a' central hole in the other, a cap on the latter merinber surrounding the. und lated way of the former member, and means for turning one 7,

member'relativelyto the other; of a "series-i,

of rollers disposed between said ways, a

ring shaped spider surrounding therollers and standing within said cap and betwee'n I said ways, and pins ,pro ectin'g from the.

spider radially inward and" on whichsaid rollers arejournaled, the inner'euds of said pins bein free and out of contactwiththe shank an having heads for the purpose'set 'forth. 4
