Description

NiTED STATES PATENT rricnl OLIVER H. WALLEN, OF MARSHALLTOW N, IOWA.
WlNDMlLL-SPRING.
SPECIFICATION forming part of Letters Patent No. 548,484, dated. October 22, 1895.
Application filed April 16, 1895. Serial No. 545,980- (No model.)
which the following is a specification.
The object of my invention is to make a windmill spring which will do away with the sudden jerk in the pump-rod produced by the windmill-crank as it passes from a downward to an upward or upward to a downward stroke in both the up and down strokes.
Figure l of the accompanying drawings is a vertical section of the entire wind millspring, showing the two castings M and N with their helical proj ecting bosses p, t, 'v, and u. S is the coil-spring surrounding the two castings M and N. Fig. 2 is a front view, showing the appearance and shape of the two 4 castings and bosses.
Similar letters refer to similar parts in both figures.
The pump-rod passes through the center of the spring, and being vertically under the mill-rod the line of action of the resultant force in the mill-rod and that in the pump-rod will lie and act in' the same vertical line, the center line of the spring, and have therefore a direct central pull.
iVith these objects in view the mechanism constructed consists of a spring S and two castings M and N, Fig. 1, each of which occupies one-half of the inside of the spring. '12 and u are two spiral bosses on the casting N. p and t are two spiral bosses on M, having the same pitch as the spring, as can be seen in Fig. 2.
The method of construction is as follows: One of the two castings is first slipped through the spring into its place. The other casting is then started at one end and screwed in by turning both castings. The one in place simply turns around in its position. It is now ready to be put on the mill. The upper end of the pump-rod passes through the hole to and centrally through the spring, being fastened by a pin through Z. The lower end of the mill-rod is suitably fastened to the upper 'end of the windmill-spring and is centrally located with respect to the spring, thus giving us a direct central pull and thrust in the upward and downward strokes, respectively. Vhen the mill-rod begins its upward stroke the casting M pulls up suddenly. Ntending to remain in its original position, the spring is consequently compressed by the action of the two bosses p and a, and the sudden jerk is thus overcome. Similarly in the beginning of the downward stroke the spring is compressed by the action of the bosses at and t, and the sudden jerk is again overcome, thus making a double-acting wind mill-spring, and may be used on a double as well as a single acting pump.
I-Iavingthus explained my invention, what I claim as new, and desire to secure by Letters Patent, is
A rod connection comprising two similar castings, each provided with a semi-cylindrical extension, helical projecting bosses at the top and bottom of said extensions, and a coil spring interposed between the aforesaid bosses and encircling both of the extensions, as described in the foregoing specification.
