Description: |
"Double acting pumps with single pistons are by no means new; they were not so when used at the old water works in Philadelphia, nearly thirty years ago; they are now employed in an improved form at the new works, and have been variously modified, according to the purpose for which they were required, or the fancy of the maker. To those who understand the construction of Boulton and Watt's double acting engine, it is only necessary to say, that the pump for which Mr. Wileman has taken a patent, resembles it very closely. Imagine the induction, to be the supply pipe and the eduction, the delivering, or discharging pipe, and you have the whole apparatus. In the plate which forms the bottom of the cylinder, there are cavities to connect it with the supply and discharge pipes; these are claimed by the patentee, and are, in fact, the only things absolutely claimed, the remainder being conditional, and in the subjoined words, the other parts described in this specification I claim only so far as they shall be found original with myself. The patentee thus leaves it to others to discover what is new in the construction of his machine, a task which, we apprehend, the law will not impose upon them, and, if it did, it is one which we fear they might find it difficult to perform." (From the Journal of the Franklin Institute, Oct. 1829, pgs. 251-252.)
