catalogue of Crane Co. n v a a i V p i i Another important object of 'this'invention is i the provision of a cock plug with integralhead of materially less weight than heretofore and yet' which dispenses with the intricate and expensive coring of prior heads while permitting theuse n of a regular wrench. Howeven it discourages the use of a pipe wrench ornother zu nsuitable tools by :reason of its outer cored suriacesor recesses.

Qf Q QJhe Q r s amless cr ii al l r reducing the'heavy metalsection of theiornierly solid head andin so doing reduce substantially s the amount of metal necessarily used and simul-' taneously reduce the large percentage of foundry scrap previouslyoccasioned by using a solid head for these plugs applied to the kind ,of valves shown for example on page 92 of theNo; 41

Other and furtherimportant objects willbethe accompanying drawing, in which i Fig. 3 isa plan vealed-th the e squ el; a h 31 ture betweenthecentralor bo up o hea P ns} enus; pr i'zib cause the body portion of the plug was cored a out the pas e-s rs; ,as-i id x i d by-i e d tted lines 5, with the result that the body portion of the plug was merely a shell havingahollow 3 interior with comparativelyfthin. wall sections of metal as compared with the upper solidhead lportion'o f the plug. It wouldseem that the obvious solution resided in coring the head as well as the plug. However this would entail intricate and relatively expensive coring, Also the prob lem would not be entirely solved inasmuch as a with a solidand virtually unbreakable plughead might easily use a pipe wrench or other unduly heavy tool to operate thevalve with the result that excessive torque \wouldjbe exerted on the hollow head to causebre'akage of the casting.

i come apparent from the disclosures in the folit [lowing specification, and I and between the radially extending ribs I reinforced the head sufiiciently to withstand any reasonable torque which an operatormight apply As shown in the drawing, the general reference character A indicatesa valve body in Y whichv the numeral I, indicatesithe .cockvalve plug closure incorporating theinstant invention and is provided with the customaryinlet and} outlet ports 2 and 3 and the elongated passage way 4 joining theports 2 and 3. Thejjplug 'l is :provided with the novel head 6 having the radially extending ribs? formedby recessing pori tions of a full square head, as indicatedbut addii tions I3 thereby permitting the use of a regular square hole wrench to engage this novel plug It was thus determined 'thatthe ultimate solution was not incoring but rather by way of a 1 properly designed head' in the patternitself.

After the segments f the plug head 6 had been 7 removed from the head bychanging the pattern, it became evident that thejplug head 6 with,

radialribs I alone was not sufliciently strong to withstand the relatively high torque applied dur- V 1 ingthe opening'and closing operation ofthe cock Fig. 2 is a side elevation oftheplugjof this invention taken at righti angles to theelevation fiotFigtl. m i v Q1 in view of the plug as shown in or plugvalve, It'was discovered that a horizontally extending webbed portion 9 extending over to the valve in the course of operation.

A'valve plug havingan upwardly extending i head portion, the said headportion having its sides relieved toforin radially extending ribs,

aweb-like cover for thesaid head portion, the

said ribsand fvveb-like cover providing means for engagement'of a wrench'having a polygonal "3'. A valve plug or the like having an extension "atfone' end thereof, the said extension comprising a solid central portion and radially extending ribs; a substantially horizontally extending web 'at the't'op of the said extension joining the said ribs. m

fl. A valve plug having an extension at one end and the relieved sides a and walls. we

thereof, the said extension comprising a central portion and radially extending ribs forming a substantially X-cross-section, a web at right angles to'the top portion of the said ribs, the said ribs and web adapted to receive a polygonal hole wrench for efiecting. rotative movement of the said plug.

5. A valve plug having an extension at an upper end portion thereof, the said extension comprising a central portion and radially extending ribs, a horizontal web at the top of said extension joining thesaid ribs, the said ribs' being of substantially uniform length and thereby adapted to receive a wrench with a polygonal opening to effect rotation of the plug.
