T all whom t may concern.' v
Be it known that I, CARL E. L. LIPMAN, a citizen of the United States, residing at Beloit, in the county of Rock and the State of Wisconsin, have invented certain new and useful Improvements in Air-Motors, of which the following is a specication.
The object of this invention is to construct a rotary valve for a multiple cylinder air motor, comprising a solid shaft through which inlet and exhaust ports are formed.
In the accompanying drawings: Figure l n is a longitudinal vertical section. Fig. 2 is a section on the line a a of Fig. 1. n Fig. 3 is a section on the line b b of Fig. 2. Fig. 4 is a section on the line c c ofFig. 1. Figs. 5, 7 and 9 show the positions of the intake port for the cylinder 2, on the line Z d of Fig. 1. Figs. 6, 3 and 10 show the positions of the exhaust port for the cylinder 2 on the line e e of Fig. 1. Fig. 11 is a diagram `illustrating the portion of a revolution of the valve, the intake and exhaust ports are open, and the portion of a revolution in which both ports are closed.
The motor shown in the drawings comprises the base l supporting the cylinders 2, 3 and 4. A crank shaft 5 is supported by the base and to it are connected the three pistons 6, 7 and 8 for the cylinders 2, 3 and 4. A spur pinion 9 is connected to the crank shaft 5. The upper ends of the cylinders are formed with an outwardly extending flange 10. To the shaft 5 maybe connected a gear lor other means of transmit-` ting power. Over the open upper ends of the cylinders is located a valve casing 11 provided with aflange 12 by which it is connected with the flange 10 by the screws 13. This casing has a longitudinal cylindrical bore'14 within which is located the rotary valve 15. `A cap 16 has a screw thread connection with the one end ofthe valve casing and covers one end of the borer 14 and prevents the lengthwise movement of the rotaryl valve. A gear casing 17 is supported at its lower end by the crank shaft casing 1 and at its upper end by the valve casing 11. A cover 18 to the gear casing is connected by the screws 19. A spur gear 2O is connected to therotary valve 15, and
intermediate spur gears21 and 22 are sup-` ported by the casing 17 and cover 18 and mesh with the spur pinion 9 and spur gear 20, thereby forming a driving connection be- 15. The relative speedof the crank-shafty and rotary valve is two revolutions of the crank-shaft to one of the rotary valve. The upperr portion of the valve casing isformed with two cavities or compartments 23 and 24. The compartment 23 has an intake port 25 and the compartment 24 has an exhaust opening 26. f
As there are three cylinders, there` are three intake ports 27, 28 and'29 andthree exhaust ports 30, 31 and 32 for the cylinders 2, 3 and 4 respectively. i tend vvertically through the per walls of the central casing 1l,
rIhrough the rotary valve l are formed three intake ports 33, 34 and' 35 and three exhaust ports 36, `37and 38 for the kcylinders 2, 3 and 4 respectively VThese ports are arranged longitudinally of the rotary valve so that each cylinder is provided with an intake and an exhaust port. By fitting the rotary valve casing with a rotary valve all of the parts in it can be machined inbore 14 the valve These ports exlower and updependently of the cylinders and crank-j shaft casing, and by forming the intake and exhaust ports of the casing in vertical alinenient and the ports in the rotary valve radially therethrough, the intake of the air and exhaust from the cylinders have a direct passage.
Figs. 5, 7 and 9 show the positions of the intake port 33, and Figs. 6, 8 and lO show the positions of the exhaust port 36 during one reciprocation of the piston 6.
Fig. 1l shows that the air is admitted during 128, the exhaust is open 2200, and both intake and exhaust are closed during 6 between the intake and exhaust and between the exhaust and intake. l
I claim as my invention:
In a motor, the combination of a series of lpower cylinders arranged in alinement, a valve casing extending over the upper ends ingestablislied between said casing and each of said cylinders through an intake and exhaust port in the top of each cylinder, said ports being arranged throughout the length of the casing so that the' inlet ports of adjacent cylinders are disposed in proximate relation and the exhaust ports of adjacent cylinders are also disposed in proximate relation, each pairy of inlet'y ports alternating u c l of said alined cylinders, communication bein position with la pair of exhaust ports, a partition dividing said valve casing into an In testimony Whereofl I have hereunto set my hand in presence of two subscribing Witinlet chamber including` all of, said inlet nessens.
