To all whom ¿t may concern: the center of the pump-cylinders and the cen Be it known thatI, DAVID A. DECROW, a ter of the crank-shaft. Again, the connect citizen of the United States, residing at Lock .ing-rod from the main shaft has heretofore port, in the county of Niagara and State of been attached to the upper end of the workin g 55 New York, have invented a new and useful engine ­ beam. Such construction necessi Improvement in Pumping-Engines, of which tated the placing of the driving-motor at an the following is a specification. objectionable distance from the pump to be This invention relates to pumping ­ en actuated thereby. Examples of engines em gines, and particularly to horizontal pump bodying these constructions are seen in Pat IO ing-engines of the compound or Woolf type. ents No. 263,694, dated September 5, 1882, The object of the invention is to improve and No. 289,828, dated December 11, 1883, the construction of pumps of this class and to Gaskill, and also in No. 455,868, dated July to render the same more efficient in opera 14., 1891, to I-Iall, with which patents I am tion. familiar. 65 A further object of the invention is to pro In order to avoid the objections noted and vide an arrangement and construction where‘ to provide a construction wherein the power by the size of the pumpe-vlinder will not be of the drivingsteam-engine is most effect limited by the relative location and arrange-f ively applied to the Work of actuating the ment of the crank-shaft. . pump-plunger and to provide a construction 70 A further object of the invention is to pro wherein the driving steam~engine may be vide an arrangement and construction where placed in as close proximity to the pump as in the main crank is connected directly to possible and a construction wherein the size“ the cross-head of the steam-motor. of the pump will not be limited, I provide Other objects of the invention will appear the following construction: 75 .25 more fully hereinafter.
