posed' lbetween the.; rear end of the' cylinder. and the head 7 to obtain an air-tight joint 'at thisend'. On the for-Ward end of the base, which has a form Whieh permits its com process, is a .bearing lug 2G tov which E2 is pi-voted aY double elbow' form lever 2S at the lower elbow29 of which is pivoted at 30 the piston-rod l0. The dotted lines in Fig. l indicatethe relation ofthis lever to the cylinder Whenin folded position. ln this folded position a. portion 3l of the lever ex- `tends horizontally from the pivot 2T toward kthe cylinder While a' portion rises Yerti cally and projects the body of the lever above the cylinder Where said bodyfin folded position overlies and `is parallel with the cylinder. On the free end of the lever 2S is av lug orsocletl portion 33 'which is engaged by'a hollow end or socket 3l (if a lever extension or handle When the lever Z8 foldedover the cylinder the lug 33 projects upwardly at anangle, as shown in Figs. i and G. The socket 3l projects from one side tot the handle so that the lug mayenter the socket openingr from either of its ends. ll'licn the lever 28 is folded over the cylin der the `handle :25 non' have its position rethe--heads Tand 9 are secured to the cylinder 1 by means of connecting rods Q0, Qlfandf 'each oli/.which has ahead Q3 on one end and a. nutl Zithreaded on' the'fopposite end, a suitable.fiberringor gasket .25 being inter struction by either the die or nioldinfr.,

versed, ne indicated in Figspl, 5 and 6, to make it lie alongside of the lover 28 and to not project eniiratuntiully beyond the ends of the baise 3 lever extensions it is usual to fasten the extension or handle by ineens of o :short bolt or other device which takes time to adjust. The

Vincliinitifm of the lug; olivintee the necessity of suoli fastening oeoause jarring; of the parte tend to iieep the socket und lug engaged. It also olwizitee the weakening of the parte by providing :i ooit liole nt thin ceives the upper jow of the clump and ein tends morose the bose eotl'mt the end of the screw 38 of the clump muy be brought to bear against the medion line of the onse and thus prevent its tiliping Whenthe pump is actuated, ne when tile jaws of the Clamp engage only one edgeor eide of `tine base. In
