STEAM-ENGINE.
SPECIFICATION forming part of Letters Patent No. 752,237, dated February 16, 1904.
Application filed October 17, 1902. $erial No- 127,'736. 1N0 model.)
To all whom it may concern:
Be it known that I, ALFRED S. LINEBACK, a citizen of the United States, residing at Ophir, in the county of Tooele and State of Utah, have invented certain new and useful Improvements in Steam-Engines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the. art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.
My invention relates to steam-engines; and the principal object is to provide means for obtaining two revolutions of the drive-shaft or belt-pulley for two complete strokes of the piston, the full outstroke of the piston giving three-quarters of a revolution, while the .full instroke gives one and one-quarter revolutions.
Another object of my invention is to pro.
vide means for securing perfect alinement of the piston to reduce friction and to insure a smooth action.
Still another object is to provide means for automatically controlling the feed of steam to the piston-heads and regulating the exhaust from the steam-chest.
These objects are attained by means of the construction illustrated in the accompanying drawings, in which Figure 1 is a side elevation of an engine made in accordance with my invention. Fig. 2 is a longitudinal section through the cylinders and steam-chest. Fig. 3 is a detail plan View of the slide-valve. Fig. A is a section through the pivoted point of the oscillating stay which controls the alinement of the piston. Figs. 5, 6, and 7 are diagrammatic views illustrating the different positions assumed by the link and lever connections to the belt-pulley during one stroke of the piston.
Like characters of reference designate like parts wherever they occur in the diflerent views of the drawings.
The numeral 1 designates the steam-dome, and 2 3 are the cylinders, said cylinders being separated by a partition 4:. The dome and cylinders are supported upon suitable masonry,
ger 11, arranged in the line of movement of the cylinder-heads 12 and designed to be moved by the cylinder-heads to uncover one of the ports 10 at each reciprocation of the pistons to admit steam from the dome to one eylinder. A double puppet-valve 13 is centrally pivoted at la-immediately under the partition 1, and the valve-heads 15 of the puppet-valve 13 alternately cover and uncover the ports 16 v in the cylinders, a guard 17 being arranged below the puppet-valve to prevent a direct exit of the steam. The piston 2 is mounted to slide at its outer end in the guideway 18, while the piston 3* is connected at its outer end to a pitman 19 bya pivot-pin 20. A connecting-rod 21 is attached at its outer ends to the ends of the piston-rods 2 3, as shown in Figs. 1 and 2. An oscillating stay 22 is pivoted to rock upon the pin 20, and pivotally connected to one end of the stay 22 is a lever 23. the lower end of which is pivoted at 24 to the floor or support for the engine. The opposite end of the stay 22 is connected by a lever 25.130 the bracket 26, secured to the ceiling. A belt-pulley 27 is keyed to the shaft 28, and said shaft is mounted to, revolve in standards 29, secured to the floor. Pivotally connected to one of the spokes of'the belt-pulley 27 is a link 30, and the opposite end of this link is pivoted to the end of the pitman .19. A lever 31 is also pivoted to the end ofthe pitman 19, and the opposite end of the lever 31 is pivoted at 32 to one of the standards 29.
The operation of my engine is as follows: When the pulley and link connections are in the position shown in Fig. 5, the piston 3 is at the extreme inner limit of its stroke. As
the extreme outer limit of its stroke.
bring the pulley back to its initial position will now require one and a quarter revolutions of the pulley, and this is accomplished in the followingmanner: The lever 31 travels from the point a (see diagrammatic figures) to the point 6 at the beginning of the instroke of the piston, the link being moved in the segment of the circle shown in dotted lines in Fig. 6 from the point 6 to the point 0. While this is being accomplished the piston has traveled inwardly on a direct line a distance only equal about one-third of its instroke and the wheel has made the other quarter of the revolution needed to complete its first full revolution, it having only made three-quarters of a revolution on the full outstroke of the piston. The lever 31 now moves from the point I) to the point d, and while this operation is taking place the link 30 has forced the wheel 27 around a full revolution, bringing the piston back to the full limit of its instroke. Thus for each full stroke of the piston the pulley 27 makes two full revolutions.
It will be understood, of course,that a crankshaft may be used instead of the pulley 27.
Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is
1. A steam-engine,comprising a cylinder, a piston, a piston rod, a pitman connected to said piston-rod, a crankshaft, a link pivoted to the crank-shaft and to the pitman, and alever pivoted to the pitman and to astationary support, whereby two revolutions are impartpivoted to the pitman and to a stationary sup- 4 port, an oscillating stay pivoted to said piston and pitman, and upper and lower levers pivotally connecting said oscillated stay with fixed supports.
3. A steam-engine comprising a cylinder, a piston, a pitman, a crank-shaft, a link pivoted to the outer end of said pitman, said link being pivoted eccentrically to the crank-shaft, a lever pivoted to the pitman and link and to a stationary support whereby two revolutions are imparted to the crank-shaft by the in and out strokes of the piston.
4:. A steam-engine comprisingacylinder, a piston, a pitman pivoted to said piston, a crank-shaft, a link having one end eccentrically pivoted to said crank-shaft, a lever pivoted to said pitman and link, an oscillating stay pivoted to the piston and pitman, and upper and lower levers pivoted to said oscillating stay and to fixed supports, whereby perfeet alinement is obtained for the piston.
In testimony whereof I afliX my signature in presence of two witnesses.
ALFRED S. LINEBACK.
