Definitions

  • NV PETERS PHOTO-LITHOGRAPNER, WASHINGTUN. D C.
  • JESSE TUTTLE OF BOSTON, MASSACHUSETTS.
  • ⁇ revolves in the metal shell or case 1, which is firmly bolted to a wood or metal frame.
  • the case or shell 1 is made in two parts, and is secured together by means of bolts and iianges at its circumference.
  • Each half of the shell or case 1 is turned out. on its inside to fit accurately to and correspond with the shape of the piston 7 and the rim of the rotating plate 5', so that the shaft 6, with its rotating plate 5 and piston 7, can turn freely inside the shell or case, the chamber 2, in which the piston 7 revolves, being annular and of the shape and size of the piston 7, which may be round or square or otherwise.
  • the journals for the shaft to turn in are formed in the center of each half of the shell or case 1, and are made steam-tight by means of stuiiing-boxes.
  • valves 9 which form the abutment for the steam in the annular chamber 2.
  • These valves 9 are placed opposite to each other in a line drawn through the center of the annular chamber 2. They are fiat plates of metal, rather wider than the chamber, being faced perfectly smooth and true upon 'their faces and edges. They slide in two chambers or cases made fast to the shell or case and in slots or grooves in the sides of the annular chamber 2 up to the rim of the rotating plate 5.
  • Each valve 9 has a rod or stem moving steam-tight through stuffing-boxes in the ends of their chambers.
  • Each rod or stem has a branched or fork piece 10 embracing ⁇ the outer shell or case 1.
  • To each arm of these forked or branch pieces is iixed a pin projecting inward toward the rotating plate 5, having a steel roll 1l upon it, which fits into the cam-shaped groove 8, formed upon the side of the rotating plate 5, so that as the rotating plate 5 revolves the valves 9 are moved at times according to the shape of the groove 8, being guided in a horizontal line by the slots in the side of the shell or case, into which the rolls 11 fit likewise.
  • the extreme point of the cam part of the groove is in a line drawn from the center of the piston 7 to the center of the rotating plate 5, the center of the circular part of the groove being the center of the shaft 6 and the rotating plate 5. While the rolls 11 are in this part of the groove of course the valves 9 are stationary.
  • the cam part is so shaped that a little while before the piston 7 reaches the valve 9 it begins to act upon that valves rolls 11 and push itinto its case out of the way, the remaining part of the cam 8 drawing it back into its former position when the piston 7 has passed it.
  • the object of this arrangement is to prevent the friction of the packing 1t in the chamber 12, which is connected with the eduction 18, caused by the pressure of the steam against the rotating plate that forms one side of the opposite chamber 12, that is connected with the induction 17 I will now describe the operation of the engine.
  • the steam having been admitted into the steam-chest 16, the slide-valve 19 is moved by means of its handle so as to open the port of the side pipe 15, which communicates with the end of the piston 7 opposite to the direction in which the piston 7 is required to rotate, and connecting the port of the side pipe 15 (which communicates with the other end of the piston 7) with the eduction-pipe 18.
  • the steam then rushes through its port into the open side pipe 15, thence into the steam-chamber 12 connected with that pipe, then through the steamway 13 in the rotary plate 5 into the annular chamber 2, filling the space in the chamber 2 between the valve 9 and the piston 7, which it forces round in a continuous rotary motion, the steam escaping by the opposite steamway 14, chamber 12, and side pipe l5 into the eduction-pipe 18 by shifting the valve 19,tl1e side pipe 15, and way 13, which admitted the steam, is connected with the eduction 18, when the piston 7, rotating plate 5, and driving-shaft 6 will be rotated in the opposite direction.
  • the driving-shaft 6 is connected by gearing or immediately to the work to be done.
