Specification of Letters Patent.
Patented March 6, 1906.
Application filed October 10. 1904. Serial No.227,848.
T0 aLZ whom, it may concern: 1
Be it known that I, ISADOR LEHMAN, a citizen of the United States of America, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Engines Operated by.
Fluid Under Pressure; and I hereby 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 pertains to make and use the same.
This invention relates to improvements in upright engines operated by fluid under pressure.
One object of this invention is the provision, in an upright engine, of such a simplified operative connection between the piston of the cylinder of the engine and the crank of the engine-shaft that the required reciprocations or movements of the piston and the connected pitman are not only materially shorter than would be the case if the said pitman were directly connected with the crank,
but that the arrangement of the parts is convenient, that the number of parts required to form the aforesaid operative connection is reduced to a minimum, and that the provision of a guide-rod arranged parallel and movable with the piston-rod is accommodated.
Another object is to provide a simple and meritorious stationary framework for the engine, which framework is composed of members which are readily assembled and secured in place;
With these objects in view this invention consists in certain peculiarities of construction and arrangement and combinations of parts hereinafter described, and pointed out in the claims.
The accompanying drawing is a side elevation, largely in section, of the greater portion of an upright steamengine embodying my invention.
Referring to the drawing, A designates the vertically-arranged cylinder of an upright steam-engine, a the piston contained within and adapted to operate endwise of the cylinder, and B the stationary framework of the engine.
The framework B comprises a horizontally-arranged base-plate 3, a horizontallyarranged top plate 5, and an intermediate horizontally-arranged plate 4. The plates 3, 4, and are suitably spaced vertically and parallel. The intermediate plate 4 is arranged nearer the top plate 5 than to the 'base-plate 3.
The base-plate 3 rests upon the floor or foundation C, upon which the en gine is mounted. The framework B also comprises any suitable number of upright posts formed by rods 6, which extend vertically through correspondingly-arranged holes 2, formed in the plates 3, 4, and 5, and a suitable distance above and below the plates 5 and 3, respectively. The end portions of the rods 6 are screw-threaded externally, and correspondinglyscrew-threaded nuts 7 are mounted on the said rods next below the base-plate 3, and the floor or foundation C is reduced, as at 8, to accommodate the location of the said nuts. Also nuts 10 are mounted on the rods 6 next above the baseplate 3. The nuts 7 and 10 secure the vertical posts formed by the rods 6 to the'baseplate 3.
The plate 4 is mounted upon the upper ends of tubes 13, which embrace the rods 6 and extend between the said plate and the nuts 10 and rest upon the said nuts, and consequently upon the base-plate 3.
The. top plate 5 rests upon the upper ends of tubes 14, which embrace and extend longitudinally of the rods 6 between the said plate 5 and the plate 4 and rest upon the lastmentioned plate. Nuts 12 are mounted on the rod 6 next above the top plate 5 and hold the said plate down upon the tubes 14-. It will be observed, therefore, that the framework B is simple in construction and composed of sections which are readily assembled.
The cylinder A is mounted upon the plate 5. The rod or stem 15 of the piston (1 extends vertically through the lower head of the cylinder and through the topplate 5 into the space between the plates 4 and 5, and the plate 5 is slotted, as at 9, to accommodate the location and operation of the piston-rod.
The engine-shaft G is supported in any approved manner from the plate 3. The shaft G is arranged horizontally and. at a right angle to the travel of the piston a, and g indicates the crank of the said shaft. The plate 3 is slotted, as at 1.6, to accommodate the location and operation of the shaft G and its crank g, and the floor or foundation C is recessed, as at 18, to accommodate the location and operation of the said crank. The shaft G is provided with a fiy-wheel 17, and the floor or foundation C is recessed, as at 20, as shown in dotted lines, to accommodate the location of the said wheel.
An upright pitman f extends from the lower end of a piston-rod 15 downwardly and is pivoted at its upper end, as at 22, to the said rod horizontally and parallel with the engine-shaft. The plate 4 is slotted, as at 23, to accommodate the location and operation of the pitmanf.
A lever h is arranged to oscillate in a vertical'plane between the piston-rod 15 and the engine-shaft G. The lever h is journaled upon an axle Z, which is arranged horizontally preferably exactly vertically above and parallel with the shaft G. The axle Z is suitably supported from the plate 4, which is slotted, as at 24, to accommodate the location and operation of the lever h. The lever h is preferably an angular lever depending from the axle Z and provided below the pitman f with an upwardly-projecting arm 25, to which the said pitman is pivoted at its lower end, as at 26, horizontally and parallel with the shaft G.
The pivotal connection between the lever 7L and the pitmanf is arranged at one side of the axis of the said lever, and the lever h is operatively connected at the opposite side of its axis by means of a rod or link m with the crank g of the shaft G. The link m is pivoted at its upper end, as at 28, horizontally and parallel with the shaft G to the lever h. The link m at its lower end loosely embraces the wrist 27 of the crank g.
Between the axis of the lever h and the travel of the piston-rod 15 and parallel with the said travel is a vertically-arranged guiderod 1, which extends vertically loosely through the plates 4 and 5 and has lateral bearing in the said plates, and the piston-rod 15 and the guide-rod r are connected together between the said plates by a web 30, which is fixed in any approved manner to the said rods.
The peculiar shape of the lever 7c shown and hereinbefore described accommodates the location and operation of the guide-rod r.
The relative arrangement of the parts is such that the pivotal connection between the link m and the lever h is substantially as far from the axis of the said lever as from the pivotal connection between the lever h and the crank g and arranged. lower than the pivotal connection between the pitman and the said lever, that the distance from the pivotal connection between the pitman f and the lever 7b to the axis of the said lever is approximately one-half the distance from the said axis to the pivotal connection between the lever and the link m, and that the pivotal connection between the lever and the pitman is located farther than the axis of the lever from the pivotal connection between the lever and the link m.
