IMPROVEMENT IN SPINDLE-BOLSTRS.
The Schedule referred to in these Letters Patent and making part of the same I To all whom it may conce/rn:
Be itknown that I, ISAAC P. RICHARDS, of Whitinsville, in the county of Worcesteigand State of Massachusetts, have invented a new and useful Im provement in Spindle-Bolstcrs; and I do hereby declare that the following specitication, taken in connection with the drawings, making a part of the same, is a full, clear, and exact description thereof'.
Figure l is a side elevation.
Figure 2 is a top view.
Figure 3 is a view in section.
Many devices have heretofore been contrived for supplying' a bolstered spindle, or rapidly-revolving shaft, with a constant supply of oil, whose How to the bearing shall be regulated by the necessities of the case. Many of these devices employ the principle of the capillary attraction existing in tibi-ous materials, as a means for conducting the lubricant to the bearing. My invention consists in a peculiar construction of the oil-reservoir, whereby the current created by a rapidly-revolving spindle or shaft, is made available in ldrawing the lubricant to the bearing, without the aid ot' any fibrous absorbent whatever'.
A represents a bolster, in external form quite like those in common use;
B is an annular chamber tity of oil; and
C is the spindle or shaft-bearing.
for the deposit of a quanf It will be noticed that the wall of the oil-chamber next to the bearing is not perpendicular to the plane of the bottom of suoli reservoir, but is inclined thereto, as seen at a a. In other words, the metal about the bearing would, it' extended so as to meet in a point in the axis of the bearing, make the figure of a cone.
Oil, or other liquid lubricant, having been placed in the annular chamber B, it will be found that the i current of air set in motion by a rapidly-revolving spindle, will cause a film of oil to flow up the inclined side a a of the chamber to the bearing, without the employment of any conductor possessing the power of capillary attraction.
The rate of supply of oil to the bearing should be in proportion to the necessities of the case, and can be increased or diminished by varying the angle of inclination of the side a a to the axis ot' the spindle.
The speed of the. spindle being known, itvwill be' easy to determine, by experiment, in any particular case, the degree of inclination required for the side of the chamber.
I have found that for spindles making the usual number of turns per minute, the .ngle shown inthe drawings allows the requisite quantity of oil to i'low to the bearing. For spindles'making less than this number, the angle of the face ofthe cone-shaped side of the chamber to the axis of the spindle should be proportionately greater, and vice versa.
I do not limit myself to any particular angle of inclinatiou to be given to the wall of the oil-chamber, as such angle must be proportioned to the speed at which the spindle is to run.
What I claim as my invention, and desire to secure by Letters Patent, is-
Ihe improvement in holsters, which consists in constructing the wall of the oil-reservoir B, next to the bearing, with its face a a inclined to the axis of the spindle, substantially as described for the purpose specified.
ISAAC P. RICHARDS.
