Specification of Letters Patent.
OSOlLLATlNG-PISTON ENGINE.
Patented May 22, 1906.
Application filed May 17, 1905. Serial No. 260.866.
To all whom it may concern:
Be it known that I, J OHN BERGESEN, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn,
in the county of Kings and State of New' York, have invented a new and Improved Oscillating-Piston Engine, of which the folto Barger, No. 683
lowing is a full, clear, and exact description.
The invention relates to a peculiar form of oscillating-piston engine useful in connection with fluid under pressure. It is especially designed as a steam steering-gear for marine vessels.
The invention belongs to that class in which a quadrant-shaped cylinder is pro- I valve, so as to render the action of the engine which is located the piston-wing 11.
more certain and rapid than heretofore, and to avoid loss of steam and difficult operation.
The invention resides in certain specialfeatures of construction and combination of parts, which will be fully set forth hereinafter and pointed out in the claims.
Reference is to be had to the accompanying drawings, which illustrate as an example th e'preferred embodiment of my invention,-
111 which drawings like characters of reference indicate like parts in the several views, and in which Figure l is a vertical section of the motor. Fig. 2 is a section on the line 2 2 of Fig. 1. 3 is a section on the line 3 3 of Fig. 1. Fig. 4 is an enlarged section. on the line 3 3 of Fig. 1, but showing the valve in open position; and Fig. 5 is a detail section of the valveseat.
10 indicates a quadrant-shaped cylinder a1 piston is carried by an oscillating shaft 12, which is located coincident to the center around which the piston 11 swings. The shaft 12 asses out from one end of the casing or cylindiar 10, a stufiing-box 14 being pro: vided to prevent 'leakageattliiapoint, and as here shown the shaft is provided with a s'ector with a port 23.
and this seat will move the ports a 15, having a grooved periphery 15, with which the tiller-ropes are joined. I
The upper end of the shaft 12 projects into a housing or valve-box 16, secured to the upper part'of the cylinder or casing 10. dicates a suitable packing surrounding the, upper end of the shaft to prevent leaka e past the same. 18 indicates a steam-suppy I pipe leading to the upper part of the casin 16, and 19 indicates the exhaust-pipe. I
Suitably fastened to the upper end ofgthe shaft 12 and located within the box or chest 16 is a frusto-conical valve-seat 20. The; seat tapers from its upper to its lower end, 7'
and a packing 21 is interposed betweenlthe'jo upper end of the seat and the inner walls of the housing 16. Said seat has a port, 22 therein opening into the lower part of the housing 16 to permit the exhaust-steam to pass through the lower part ofthehousing v out by way. of the pipe 19. The valve-seat 20 is also provided on each side of the port 22 v formed in the shaft 14. These passages 24 g I.
and 25 lead down through the shaft 12 .and
communicate with the casing 14 on opposite sides of the piston 11. Operating with n the Said ports23, as shown with g; respect to one of said orts in Fig. 5, have one d for the purpose whichrf8o The ports '23 comvalve-seat 20 is a frusto-conical valve. =1This valve has ribs or vanes 26, 27, 2 8, and 29, and it is provided at its upper portionwith a cover or top wall 30, which prevents steam from passing from the exhaustchamber in the lower part of the housing 16 up through the upper part of the housing, or vice versa. The valveis adapted to rock in the seat, so as alternately to connect the ports 23 to the steam o5 supply or exhaust passage 24 or 25, as the case may be. During this movement the rib 29 rocks from one side to the other of the port 22.
Upon throwing the lever tothe position shown in Fig. 4 steam will be admitted into the passage 24 and will pass into the casing 10, moving the piston 11 in one direction. The piston carries with it the valve-'sea;.-;2 0,
Said rib 29 is provided with an 1 w E opening or openings 30, which facilitates 10o valve, so as to cut off the steam-supply, holding the piston 11 in its new position until the valve is again shifted, or if the apparatus is applied as a steam steering-gear until the condensation of steam will permit the force of the water acting on the rudder to start the piston from its new position, whereupon the piston in coming back will carry the valvecasing with it, and a fresh supply of steam will be admitted to the cylinder. This action goes on throughout the operation of the apparatus, the operator opening the steam-supply sufficiently to move the piston to the desired posit on, and this movement acting to cut off the steam, holding the piston in the position desired until the valve is again moved or until the condensation of steam in the casing permits the piston to move, whereupon the steam-supply will be again opened.
It will be observed, particularly by reference to Fig. 5, that the ports 23 have a diagonal side adjacent to the steam-supply connection 18, so that when the valve connects one of the ports 23 with the steam-supply the valve uncovers the tapering side of the port at the same time the valve uncovers the straight sideof the opposite port, and the result of this is that with the same movement of the valve a larger area is given to the port which is exhausting than to the port which is receiving the steam. This is illustrated in Fig. 4, where it will be seen from the arrows that the steam entering the engine passes the diagonal side of one of the ports 23, while the steam exhausting from the engine passes the straight side of the opposite port. It also may be seen that the live-steam ressure on top of the valve holds the same rmly to its seat, while the flat end (indicated at 36 in Fig. 1) prevents the conical valve from binding in its seat. This holds the valve tight without undue friction.
Having thus described the preferred form of my invention, what I claim as new, and
desire to secure by Letters Patent, is-
