Description: |
| Most of the patents prior to 1836 were lost in the Dec. 1836 fire. Only about 2,000 of the almost 10,000 documents were recovered. Little is known about this patent. There are no patent drawings available. This patent is in the database for reference only.
“For a Toothed Cylinder Pump; E. Lazelle and D. Bloodgood, Poughkeepsie, Dutchess County, New York, July 27.
This pump consists of two metallic cylinders working within a metal box. The cylinders are to be toothed along their whole surface, are to match into, and turn, each other, like toothed wheels. They must fit exactly into the box in which they are contained, as the teeth must work water-tight, against its semicircular ends. The box is to be closed by two heads which fit exactly on the ends of the cylinders and receive their gudgeons; one of which passes through the head for the purpose of having the crank attached to it, to work the pump. A pipe descends into the well, or reservoir, from the lower part of the box; and another pipe ascends from its upper side, through which the water is to be forced.
A pump very similar to this was patented in England, about three years since, by a Mr. Joseph Eve. "The cylinders were worked by cog wheels upon their gudgeons, outside of the box; each of these cylinders had but two teeth, or wings, which were, consequently, more easily made to fit the box, and left a larger water way; that of the present patentee being only the space between the teeth of the cylinders. We should be glad to be able to give the preference to the pump of Messrs. Lazelle and Bloodgood, but, whilst the principle is evidently the same, the difficulty of making the latter, the difference of the water way, and the amount of friction, are all against it. We have not seen either at work, but the account given of Eve's pump was a very favourable one; it is stated that with “ Cylinders 33 inches diameter, by 6 inches long, and the wings only # of an inch wide, two men turning the winches, raised 1100 lbs. of water to the height of 21 feet, in three minutes;" which considerably exceeds the power of the ordinary pump.
If a pump can be so constructed that a continued stream shall be made to flow up the shaft, instead of allowing the water to lose its momentum at every stroke, the advantage resulting will be very great. The accomplishment of this object has been frequently attempted, but the machines have either had too much friction, or were liable to get out of order, and have, consequently, been abandoned; we have not learned the final fate of Mr. Eve's invention.”
