Application filed August 9, 1915. Serial No. 44,563.
`ments in Steam-Enginesfof which the iollowing is a specification.
My invention is an improvement in the Iclass or type of multiple-piston steam-engines, and the objects are to simpllfy the construction and reduce the cost, weight, and :friction of the parts connected withkthe pistons and crank shaft, as well as to minimize friction and vibration.
'lhe details of construction, arrangement, and operation of parts are as hereinafter de-Y scribed and illustrated in the accompanying drawings, in which Figure 1 is mainly a horizontal longitudinal section of my improved engine Flg. 2 is a cross section on the line 2-2 of Fig. 1; Fig. 3 is a similar section on the'line 3 3; and Fig. 4 is a cross'secti'on, on the line 4 4; Fig. 5 is a vertical longitudinal sec tion of the engine illustrating certain de-v tails.
lln Fig. 1, the numeral 1 indicates a double crank-shaft,l 2 the long cylinder having a steam-chest 2, and 3-"3L indicate apairot pistons, or follow-heads, connected .by rods 4, while numerals 5---5a indicate another set of pistons or follow-heads 'connected' by the solid piston rod 6. v
'lhe piston 3a is mounted on a relatively short, hollow shaft 7, through which the solid rod 6 is adapted to slide, and is itself slidable in the head ot the cylinder 2. The
long piston rod 6 is connected with the' crank-shaft 1 by a rod or pitman 3, and the short, hollow, piston rod 7 is similarly connected with the crank by a rod 9. The two piston rods 6 and 7' are respectively provided with cro'ssheads 10 and'll, both ot which slide in one and the same guide 12. Thus the number and `weight ot the parte usually constituting this, portion ont' engines oit this type are greatly reduced.
is shown in Fig. 1, the rods connecting the pistons, or follow-heads, 3 3n slide through the piston 5, and, in turn, the solid piston-rod 6 slides through the pistons 3 and 3a, suitable stuffing-boxes being provided in the respective cases..
A slide valve 13` of the ordinary D-type vis arranged in the stearnchest,2, to govern inlet and exhaustof steam, and the sameI is connected with an eccentric 14, on the crankshaft 1, by means of rods '15, 15a, and a crosshead 16 workingin the fixed ide 17. rlhe rod a is necessarily -jointev` to the crosshead, asshown. rlhe position of the slide valve 13 in Fig. 1 is suchthat steam is exhausted through the three ports 18, there being one port adjacent to each cylinderhead and another midlength of the cylinder, all the said por-ts being connected with the chamber 18a of the valve, which in turn communicates with exhaust pipe 19, (see Figs.' 2 and 5). Simultaneously with the exhaust, steam is being admitted from steamchest -2a through ports 20, which are indicated hy dotted lines in Fig. 1, into the spaces21 between the pairs of pistons 3, 5 and 3a, 5, so that the pistons 3 and 5a are caused to approach each other, while the plstons 3"1 and 5 move toward the respective cylinder heads. 'lhus the power applied to pistons 3 and 3a isitransmitted by rods 4 'and hollow piston-rod 7 to cross-head 11, and
thence through connecting-rod 9 to an arm of the crank-shaft 1; at the same time,'the steam pressure or power applied to pistons 3 and 3, in opposite directions, is transmitted through the long', solid rod 6 to crosshead 10,
vand'the'nce, by connecting .rod 8, to the crank shaft 1. rlhus, the shaft being rotated, the eccentric 14 reciprocates the slide valve 13 iso that it alternately opens and closes the steam ports and edects the operation of the engine, as will be readily under?` stood without further description. ln this manner ll work vsteam in tive diderent com.- partments of the cylinder during each revolution of the crank shaft.v
1- claim: Y
1. The combination, with an engine cylinder having steam ports located at its ends and intermediately, and four pistons which areslidable in the cylinder and adapted to receive steam between the members ci each pair, of solid and` hollow .rods connected with such pistons, tvvo crossheads 'with which the piston rods are in turn connected, a single guidel which serves for both crossheads, and a double crank-shaft, and rods connecting the cranks with the crossheads as described.
2. 'lhe improved steam-engine of the'type indicated, the same comprising the cylinder having steam'ports at its midlength and ends, and'also at two points intermediate the midlength and ends, two pairs of pistons, or followheads whichare rigidly connected and s lidable in opposite directions,
alternately, as steam admitted or' exhausted between the members of each pair and the cylinderv heads, one pair of said pissolid rod which is slidable in rthe hollow one,
two crossheads-with which the pairs of pis- 10 ton-rods are respectively connected, a single guide which serves for both crossfheads, and rods connecting the latter with the double crank-shaft, as described.
