UNITED STATES CHARLES E. GIBBS, OF ORANGE, MASSACHUSETTS.
' PATENT OFFICE.
SHAFT.
SPECIFICATION forming part of Letters Patent No. 285,810, dated October 2, 1883.
' Application filed August 10, 1883. (No model.)
To all whom it may concern:
Be it known that I, CHARLES E. GIBBS, a citizen of the United States, residing at Orange, in the county of Franklin and State of Massachusetts, have invented a new and useful Shaft, of which the following is a specification, reference being had to the accompanying drawings.
This invention relates to all kinds of shafts, especially to those which support a rotating object, a water-wheel runner, or a millstone, and the like; and the object of the improvement is to prevent the bearing or step from heating by the frictional contact. V.
The invention therefore consists in a device attached to the lower end of the shaft, so as to revolve therewith, and provided with openings for the free passage of liquid or air through the same, to obviate in a great measure the heating of the bearing by the frictional contact.
The invention further consists in the novel construction and combination of the parts, as will be hereinafter more fully set forth.
In the accompanying drawings, Figure 1 represents a side elevation of a vertical shaft supporting a water-wheel runner in sectional lines, and aspindle-step in sectional lines, with my improvement applied. Fig. 2 is avertical sectional View of the anti-heating device; and Figs. 3 and 4 are transverse sectional views of the same, taken through the lines a Z) and c d, respectively. I
In the annexed drawings, B represents a vertical shaft or spindle, supporting in this example a water-wheel runner, C. To the lower end of this shaft is suitably secured a socket or sleeve, A, formed at its lower end with the concave bearing 6 to fit over and rest upon the conical bearing of the spindlestep h, as seen in Fig. 1 of the drawings. This sleeve A, near its lower end, is formed with a plurality of openings, 1' inclined downward, as shown in Fig. 2 of the drawings, for the free passage of air or liquid through them. The lower end of the vertical shaft, with the connected sleeve mounted on the spindlestep, is preferably arranged in water, and as the sleeve with the shaft revolves, the water is forced through the openings, thereby cooling and preventing the heating of the step -bearin gs. These openings 2' may be of any desired shape, preference being given to curved form and of any number greater than one.
I reserve the right to vary the construction and arrangement of parts without departing from the spirit of the invention.
I am aware that the end of a shaft has been heretofore provided with a transverse perforation, from which extends down a flaring perforation opening at the bottom of shaft onto the bearing thereof. I therefore do not broadly claim this construction.
'What I claim as my invention, and desire to secure by Letters Patent, is
1. As an improvement in anti-heati 11g att aeh ments to shafts, the combinatiomwith the shaft and with the spindle-step or bearing thereof, of the socket or sleeve secured on the lower end of the shaft, and formed with' the bearing in its bottom, and having a series of transverse openings or perforations extending above said bearing, substantially as and for the purpose set forth.
2. The combination of the rotary shaft having an imperforate lower end, the socket or sleeve receiving this end of the shaft, and secured thereto, and formed with the concave bottom, providing the bearing 6, and with the series of transverse inclined openings I, formed just above the said bottom, and inclined downwardly to correspond with the same, and the spindle-step fitting up in bearing 6, substantially as and for the purpose set forth.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
CHARLES E. GIBBS.
