HENRY MACLAURY, OF PHILADELPHIA, PENNSYLVANIA.
ENGINE.
SPECIFICATION forming part of Letters Patent N o. 668,822, dated February 26, 1901.
Application led November 22,1900. Serial No. 37,336. (No model.)
To a/ZZ whom, it may concern:
Be it known that 1, HENRY MACLAURY, a resident of Philadelphia,in the county of Philadelphia and State of Pennsylvania, have invented certain Improvements in Rotary Engines, of which the following is aspecification.
This invention comprises a revoluble shaft or member having` means for receiving the impact or thrust of successively-actuated pistons operated by steam, gas, or air, the pistons impinging against bosses or teeth having a definite relation upon a drum or wheels, to which rotary motion' is transmitted thereby. The cylinders employed for actuating the pistons are mounted so as to oscillate in order to permit the piston-rods to clear the bosses in their backward strokes, as well as for the purpose of opening and closing the ports by which the steam, air, or gas performing the work may be admitted and expelled.
In the accompanying drawings, Figure 1 is a side elevation, partially in section, of a rtary engine involving my invention. Fig. 2 is a plan View, partially in section, of the construction illustrated in Fig. l. Fig. 3 is a side elevation, partially in section, illustrating a modification of the mechanism for actuating the piston-rods; and Fig. 4 is a side elevation, partially in section, of a further modification of the mechanism for operating the piston-rods.
As illustrated in the drawings, the drivingshaft 1, journaled in suitable bearings 2, carries the drum 3, having a number of sets of bosses or teeth 4 4 4 thereon, the respective sets of bosses having such definite relation with respect to each other as to cause the piston-rods to act upon them in successive 0rder, as will hereinafter appear. The pistonrods 5 5 5, which impinge against the corresponding sets of bosses 4 4 4", are actuated by the pistons, as 6, of the cylinders 7 7 7", the cylinders being mounted to oscillate independently in bearings 8 8 8". In their respective forward strokes the pistonrods 5 5 are held in elevated positions by the balance of the respective cylinders, which vmay be supplemented by springs, as 9, thus engaging the vertical faces of thecorresponding bosses. In their respective backward strokes these piston-rods are heldin depressed position, owing to the fact that' the boss succeeding that which each has engaged bears upon the top of the corresponding rod.
The mechanism shown in the drawings is adapted for the use of steam. The cylinders are provided with ports, as 10, which register alternately with inlet-ports, as 11, of the steam-chest 12, having a steam-supply pipe 13, or with outlet-ports, as 17, communicating with the exhaust-steam chest 18, having the exhaust-pipe 19 leading therefrom. When a piston, as 6, is in its initial position ready for the forward stroke, the ports 10 and 11 being in registration, steam is admitted to the cylinder 7 and the rod 5 is driven forward, carrying with it the boss 4 and rotating the shaft l. When a piston-rod, as 5, has completed its forward stroke, its depression by the boss 4" succeeding that with which its end engages has brought the port of the cylinder 7 into registration with the port of the exhaust-chamber 1S, upon which the pistonrod is returned to its initial position and the cylinder-port is returned to registration with the port of the steam-chest 12. It will be seen that as the ports are controlled by the oscillations of the cylinders and as these oscillations are controlled by the relative positions of the bosses which depress the piston-rods the successive impacts or strokes are obtained by arranging the bosses of each set in advance ot' those of the next set.
The pistons may be returned to the initial positions by means of springs 15'15", having their forward ends bearing against yokes lb 16 16/l and their rear ends bearing against the respective pistons.
As shown in Fig. 3, the pistons may be returned to the initial positions by providing the cylinders with steam-ports, as 17/, which connect the front part of such cylinders alternately with a steam-inlet port 18 of the steam-chest and a steam-outlet port'19, comm unicating with the eXhaustchamber 20. With the mechanism in the position shown, the ports 10 and 11 being in registration and the ports 17 and 19' being in registration, the piston-rod 5 will be driven forward. By this forward stroke the ports l0 and 17 are brought into registration, as are also the ports 17' and 18", upon which the piston-rod will be returned to its initial position.
As shown in Fig. 4, a port 21 connects the IOO front part of the piston with a port 22 of the steam-chest 12, these ports beingin constant registration and the front part of the piston 23 being under constant steam-pressure. As the rear of the piston 23 is of greater area than its front, the piston will be driven forward when the ports and 11 are in registration and driven back when the ports 10 and 17 are in registrationv In this case a steam-spring, comprising a cylinder 24, communicating with the steam-passage 21 and having a plunger or piston 25 therein impinging upon a bearing 26, acts to elevate the pis- Ifon-rod.
Having thus described my invention, I claim- 1. In a rotary engine, a revoluble shaft, a drum or Wheel on said shaft having bosses or teeth thereon, and a cylinder having a piston and piston-rod adapted to oscillate, said shaft being driven by the engagement of said piston-rod with said bosses and said cylinder being oscillated by the engagement of said bosses with said piston-rod, substantially as specified.
2. In a rotary engine, a revoluble shaft, a
drum or Wheel on said shaft having a plurality of sets of bosses thereon, in combination with a plurality of cylinders having pistons and piston-rods adapted to oscillaie independently, said drum and shaft being driven by the engagement of said piston-rods with said bosses and said cylinder being oscillated alternately by the engagement of said bosses Wi th said piston-rods, subst-an tially as specified.
3. In a rotary engine, a revoluble shaft, a drum or Wheel xed on said shaft having a plurality of sets of bosses arranged in successive order thereon, in combination with a plurality of cylinders having pistons and piston-rods adapted to oseillate independently, and inlet and exhaust passages for said cylinders alternately opened and closed by said oscillations, substantially as specified.
In witness whereof I have hereunto set my hand this 21st day of November, 1900.
HENRY MACLAURY.
