UNITED STATES PATENT OFFICE JOHN BIRKENHEAD, OF MANSFIELD, MASSACHUSETTS.
IMPROVEMENT IN SPINDLE-STEPS.
Specification forming part of Letters Patent No. 157,437, dated December 8, 1874 application filed i October 30, 1874.
To all whom it mag/ concern Be it known that I, J oHN BIRKENHEAD, of Mansfield, of the county of Norfolk and State of Massachusetts, have invented a new and useful Improvement in Spinning-Frame Spindles and their Steps; and do hereby declare the same to be fully described in the following specification, and represented in the accompan ying drawings, of which- Figure l is a front elevation, and Fig. 2 a vertical section, of a spindle and step provided with my improvement.
The nature of my invention consists in the spindle provided with a bell-cap, and with an oil-intercepting groove extending around it and within the tubular extension of the step, in combination with the step, having an oilchamber, a tubular extension, and a cap or cover, all being as shown and described; the purpose of the said groove being to intercept oil rising on the spindle, and prevent it from being thrown out of the inner or rotary cap, and upon the outer or stationary one, and then ce flowing therefrom down upon the outside of the step.
In the drawings, A denotes the spindle; B, the step; a, the pivot ofthe spindle, and b its bearing in the step. O is a tubular extension, open at top, and projecting from the bearing I) upward out of and above the'step, and into a bell-cap, D, iXcd' upon the spindle circumferentially, so as to revolve with it. An auX- iliary cap or cover, E, fitting closely to the spindle, and closely `upon the step, and extending about thc two, also covers the cap D, and is to prevent waste from getting upon the'latter and the top of the step. The said top has a groove, c, made in and around it to receive the oil, such groove having an opening, d, leading from it into the oilchamber e. This latter chamber encompasses the spindlefoot or pivot-bearing b, and extends below its top, and there is provided with an opening, f, leading into the bore of the tubular extension, all being as shown in Fig. 2. The waste or black particles produced in the oil by the friction of the spindlepivot in its bearing will rise or be ejected from the mouth of the latter, and pass therefrom through the induct f into that part of the oil receiver or chamber e which is situated below such educt, such part serving to intercept and retain such particles or waste, and prevent the same from falling back upon the spindle-foot and bearing, and clogging or wearingthem. In that part of the spindle that projects into the tubular eX- tension, and is above the spindle-pivot, is a broad groove, h, which goes entirely around the said part. When the spindle is 'in rapid revolution, the groove serves to intercept oil and prevent its iiowage out of and over the top of the tubular extension, and thence into the rotary bell-cap. In case any oil may be caught upon the inner surface ofthe said cap,
and ow down such and out of the cap, it will be thrown off tangentially by the latter, and against the inner surface of the outer cap, and, flowing down such, will run out of the cap and down on the outside of the step, all of which, for obvious reasons, it is very desirable to avoid, and which is prevented by the groove It.
I do not claim a step provided with an oilreceiving chamber,arranged above the spindle pivot-bearing of the step. Nor do I claim a step provided with a tubular extension, to project up into the whirl of the spindle or into a cap fixed to the spindle.
I claim as my invention as follows-that is to say:
The spindle A, provided with the cap D, and with the oilintercepting groove h arranged in it, and the tubular extension of the step, in manner as described, in combination with the step B, provided with the cap E, the oil-chamber e, and the tubular extension O, all being as specified.
JOHN BIRKENHEAD.
