ends are connected by a pipe '6 which in turn 1s connected through a pipe 7 with a con'- trolling valve S of suitable construction for governing the How of motive fluid to and from said cylinders. This valve is supplied with 'motive fluid from a' suitable source through a pipe 9 and I preferably `construct it as described vand claimed in my application for U.'S. patent filed of even da'te herewith, Serial No. 800,609. Each of the cylinders 5 is open at its lower end and contains a` piston or plunger of the trunktypc, packed by a suitable gland 11 and the, necessarypack' ,q material.
Mounte in suitable bearings 12 carried, by the base plate 13v of the machine is a horizontally extending shaft 14 on which are loosely mounted two crank arms l15 respectively c'onnected. to the pistons 10 of the two cylinders by rods 416. On either side of each of thesev'cranks are' mounted the .two
members of a second 'crank 17 to whose crank pin 184is attached one end of a rodvented from separating'bya connectingbolt '22 which, however, does not prevent them from moving together when the rubber block 21 is compressed.
At opposite ends ot' the body l are mounted vertical spindles 23 serving vrespectively asjhinles orpivots for swingiugtables 24. 'When these tables arepositioned as shown in Fig; l they normally rest. upon suitably *formed portions of the upper surface of .the
body l, although they may be raised' clear of' this when desired by means of a shaft 25 supported iu suitable bearings at itsends and provided with cams 26 each ofV which designed to act upon one end of a lever 2T vfulcrunicd on the t'laineaud engaging a por- ,tiou of the table structure 21 'adjacent iisvertical spindle 223. Au operating arm '2S is provided for the shatt 25 and the cams .26
are so set that when this arm is forced down,
the rubber blocks act to prevent the transboth swinging tables Q4 are raised clear of .y the body 1 and may beswu'ng outwardly on their spindles 23;
Mounted upon the shaft 14 are a pair of coil springs 29 one end ofeach of which is ciate 'parts they at all times tend to move I the table `4 and pistons 10 to and maintain them in their uppermost positions even though said table be fully loaded. l
Under conditions .ofi use :the table 4 has fastened upon it 'one or more sets of patterns and after it has been swung on its trnnnions 2O by means of handles 32 throughan angle 'of' 180 into. "the 'position shown yin dotted lines, l,suitable flasks are mounted on the patterns. When it is desired to compact the sand in thev flasks, the valve 8 is so manipulated that motive fluid such as com-' pressed air. is alternately supplied to andA exhaustedfromthe hylinders 5 with the re.
sult that throughthe rods 16, crank arms 15 and rubber blocks 21, the crank arms 17, the rods 19 and the table 4 are alternately moved down againstl the action of the springs 29 so that said table strikes the body, being thereafterv caused to rise by the action' of said springs, with the result that the flasks are more or less violently jari'ed, thus acting on vthe sand as desired. Under these conditions mission of injurious shocks to the engine mechanism and also prevent the otherwise rapid wear Iof the connections between said parts. After the jarring or compacting operation has .been continued for a suitable time, the valve is actuated to cut ofi the motive fluid and the parts of the mold are properly connected t-ov each other and to the table '4, which is raised vto its upper position and reversed, By proper operation of the valve 8 the engines may be caused .to lower the table7 thus confining 1.the parts of the mold between the latter and the tables 24 and strongly compressing thefsand therein in the well known manner. Thereafter the valve S'may be operated tocause the engine to raise said table and the v,patterns may be withdrawn. By pressing down the operating arm 28, a partial revolution may be then given to the shaftQ- with the result that the cams 26 and levers 27 are actuated and causedfto raise theswinging tables, clear of the lparts of the frameon which they are supported and said tables may be swung out# wardly on their vertical spindles 2 3 to per-V mit the finished molds to be removed.
