g 1952 L. R. DAVIDSON HANDLE FOR VALVE sTEMs AND THE 1.1m;
Filed May 20, 1946 Patented Aug. 19, 1952 This invention relates to improvements. in handles for valve stems and the like.
The main objects of this invention are:
First, to provide a handle for valve stems or the like which is adapted to be fixedly secured to the stem in any desired position relative thereto and which may be effectively engaged with serrated stems or with round stems havingia smooth periphery.
Second, to provide a handle for valve stems and the like having these advantages which when attached presents a finished appearance, and may be attached by an unskilled person.
Objects relating to details and economies of the invention will definitely appear from the description to follow. The invention is pointed out in the claims. a v

.4 Claims. (01. 2s7 53) the invention is clearly illustrated in the accompanying drawing in which:
Fig; 1 is atop view of a faucet embodying my invention. l
Fig. 2 is an enlarged fragmentary view partially in vertical section on a line corresponding to line 2-2 of Fig. 1, an Allen wrench for adjusting the threaded set screw type of jar member being indicated by dotted lines.
Fig. ,3 is a fragmentary inverted view with the threaded jaw member in retracted position.
Fig. 4 is a fragmentary view mainly in section on line 44 of Fig. 2. s
Fig. 5 is a perspective view of the blade-like jaw member.
Fig. 6 is an inverted view of a cross type of handle embodying the invention, a valve stem being shown in section.
Fig. '7 is a side view of the handle of Fig. 6,
the stem being broken away.
In the accompanying drawing l represents a faucet and 2 a valve stem, the stem being without serrations. The handle 3 is provided with .a downwardly opening socket 4, the socket being elongated and having parallel opposed 'sides 5 spaced approximately the diameter of the stem 2 so as to laterally support the handle on the stem. The lengthwise dimension of the socket is substantially greater than that of, the diameter of the stem as illustrated in Figs. 2 and 4.
.The handle has a threaded bore 6 opening at 2 1. l" v The jaw'member 8 has 'a convex 'lu g-like boss l0 struckup centrally therefrom, this boss being in retaining engagement'with one wall of the socket. Forconvenience'in assembling the-jaw member 8 in the'handlepthe 'handle'is provided with a recess H opening to'theilower end of the recess 1. Ii 1 The screw I2 is desirably of the Allen setscrew type having a wrench receiving recess'at its outer end adapted toreceivea wrench-indicated at l3. It is provided with aconcave recess 14 inits inner end which'results in a circular jaw 15. This screw, threaded into the handle, clamps the stem against the jaw member 8, the stem being supportedlaterally"'relative to: the jaw by the side walls of: the'socket. This provides a verysecure'clampin'g engagement of the handlewith the stem, bothzwith a smooth stem and witha serrated stemasshown at [6 in Fig. 4. The handle parts are the same asin Figs. 1 to' 3. The axis of the screw l2iis disposed centrally of the cup shaped recess l4, anda lineextending coincident with the axis of thesc'rew is disposed parallel to and midwayj the parallel side walls 5 of the socket 4 and inalinement with the platelike jaw member '8 between the-jaws 9 thereof as shown in Figures 2 and 4.. This construction facilitates deep. penetration of the. jaws-into a stem of circular section in a direction-radially of the stem instead of at anangle to-the radius to prevent the handle from'shiftin'g" angularly sidewise on the stemwhen the screw 12 is tightened andto preventa too'shallow anchorage of the jaws 9 into the stempresulting in the handle loosening on the stem. The sidewall portions 5 of the elongated socket tbeingfparallel'to each other instead of agenerallyxcircular shape and being of substantial length :in 'thedirection'of the lengthof the socket -and=beingspaced' from each other a distance approximating the'diameter of the stem received" by.-the sockets: and
closely embracing the opposite;sides;of:said stem throughout the entire range Eofadjustmentof the screw I2 while embedding the-'jawxlj. thereof and the jaws Sopposedlthietd into the stem, further facilitate deep penetration of the jaws 3 and I5 into the stem in aydirection' radially of thestem instead of at amangleto the radiusto prevent too shallow anchorage 'of the jaws 9 into the stem, resultingin' thehandleloosening on 3 formed, the socket and jaw parts being the same as described except that they are formed in this boss or enlargement which results in concealing the screw threaded bore.
I have illustrated and described my invention in highly practical embodiments thereof. While the handle is especially designed for valve stems,
it is obviously adapted for use on any similar ceived in the socket, the socket being of a length substantially exceeding the diameter of the stem permitting adjustment-of the handle relative to the stem longitudinally of. the. parallel portions of the side. walls, thereof; said-handle. having a threaded bore open atiits outer end and opening to one end, of the socketpsaid. handle. having. a
slot-like recess opening to'the other end of the socket diametrically opposite the bore, a platelike jaw member retainingly seated in. said recess and having; axially spaced V-shapedjaws projecting from the recess into the socket, and a screw'threadedinto said bore adapted to clamp the stem-; between the screwand jaws, the screw having a concaved inner end. providing a jaw: having an edge of circular shape for engaging. the stem, the axis of the screw being disposed centrally of: the circle, a' line extending coincident with'theaxis. of the screw'being disposed parallel to andmid'way between the parallel side. wall portions of the socket and in alinement with the plate-like jaw memberintermediate. the axially spaced jaws thereof; said side wall portionsbeing disposed parallel tov each other for a substantialdistance inthe direction. of the lengthofsaid elongatedisocket and disposed to closely embrace the opposite. sides of said stem throughout the entire. range of adjustment of said. screw, said. screw adapteditoi embed the circularly shaped'jaw thereof and the .V-shaped jaws Lopposed thereto into the stem of circular section. 1
