ROTARY ENGINE. i
SPECIFICATION forming part of Letters Patent N o. 612,304, dated October 1 1, 1898.
Application filed July 22, 1897.
T @ZZ whom it may concern:
Be it known that I, ALMER N. BLAZER, of Mescalero, county of Dona Ana, and Territory of New Mexico, have invented a new and Improved Rotary Engine, of which `the follow-- expansively, if desired.
A the piston-head of the other piston.
The invention consists of certain parts and details and combinations of the same, as will be fully described hereinafter and then pointed out in the claims. A
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.
Figure l is a sectional plan view of the improvement. Fig. 2 is a like view of a modified form of the improvement as arranged for using the steam expansively. Fig. 3 is a like view of another modified form of the improvement, and Fig. iA is a transverse section of.
the improvement on the line l 4 of Figfl.
As illustrated in Figs. l and 4, the rotary engine is provided with two cylinders A A', connected with each other longitudinally and preferably cast in one piece, as is plainly indicated in Fig. 4, with the heads of the cylinders bolted or otherwise secured to the ends of the cylinders, as is plainly indicated in Fig. l.
In the cylinders A A are mounted to vturn in unison the pistons B B', provided on their` peripheral surfaces with piston-heads B2 B3, respectively, made spiral in form, one of said heads having a right-hand spiral groove and the other a left-hand spiral groove and one piston-head fitting into the groove formed by The pistons B B are secured on longitudinallyextending shafts O, journaled in suitable bearings on the cylinder-heads and connected at their outer ends with suitable machinery to be driven. The piston-heads terminate a suitable distance from the ends or heads of the cylinders, so as to form steam-chests D and E. The said chests D and E are connected with ports a and ZJ, leading to a reversing-valve F for connecting either of said ports wit-h a steam-inlet pipe G and an exhaust-port c to direct the live steam into either chest D or E and to conduct the eX- haust from the chests E or D to the exhaustport c. Y
Now it is evident that when the ,valve F is in the position shown in full lines in Fig. l 6o the live steam passes through the port b into the chest E and from the same into the spiral grooves'of the pistons, so as to act on the piston-heads therein and rotate the same, the steam in following the groove in one `piston pressing on the piston-head of the other piston until the steam finally passes into the chest D and from the same to lthe port c, and valve F to the exhaust-port c and to the outside.
W'hen it is desired to reverse the engine, the valve F is turned to the position shown in dotted lines in Fig. l, so that the live steam passes through the port c into the chest D to then act on the pistons, so as to turn the same 75 in the opposite direction and to be finally discharged into the chest E, from which the eX- haust-steam can escape by way of the port b, valve F, and exhaust-port c to the outside.
When it is desired to utilize the steam ex- 8o pansively, then the arrangement shown in Fig. 2 is utilized, and this engine is provided with two cylinders A2 A3, containing pistons B4 B5, having piston-heads B6 B7 mounted on shafts C', the spiral grooves of the piston- 85 heads increasing in pitch from a steam-inlet chest E toward an exhaust-chest D, so that the spiral grooves become larger to allow the steam to expand as it passes toward the eX- haust-chest D. 9o
If desired, the cylinders A4 A5may be made conical, as shown in Fig. 3, with the pistons vBS B arranged angularly to one another and with the piston-heads B10 B11 increasing in diameter from the chest E2 to the chest D2. In 95 this case the shafts C2 C3 for the pistons diverge to render the device especially serviceable for use on marine vessels, in which the shafts C2 C3 are for carrying twin propellingscrews, said shafts extending sufficiently roo apart at the stern of the vessel to accommodate two propeller-screws. It is evident that the steam may be cut off at any desired point after it leaves the live-steam chest, it being understood that the pitch of the piston-head is made correspondingly longer or shorter for the purpose. The engine herein shown and described is very simple and durable in construction and is not liable to get out of order.
In the arrangement shown in Fig. 3 Wear may be taken uprby moving the pistons from the large or exhaust end toward the live or small end of the cylinder.
It is evident that other motive agent besides steam may be used to drive the engine, and the device may also be used as a pump.
Having thus fully described my invention, I claim as new and desire to secure by Letters Patentl. A rotary engine comprising cylinders opening longitudinally into one another and pistons secured on longitudinally-extending shafts journaled in suitable bearings on the cylinder-heads and extending beyond the heads for connection With the machinery to be driven, the said pistons being mounted to turn in unison Within the said cylinders and formed on their peripheries With spiral pistonheads running in opposite directions with one piston-head tting into the spiral groove formed by the piston-head of the other piston, the said spiral grooves having a long pitch whereby the use of eXtra gearing for connecting the pistons is avoided, steam-chests at the ends of the cylinders into which open the valve at the junction of said ports, the said valve being located between a steam-inlet port and an exhaust-port and controlling the inlet and the exhaust, substantially as shown and described.
