BEARING FOR SPINDLES OF SPINNING-MACHINES.
SPECIFICATION forming part of Letters Patent No. 305,969, dated September 30, 1884.
Application ined october 11, resa. (No model.)
T0 @ZZ whom t may concern:
Beit known that I, ALBERT R. SHERMAN, of Pawtucket, in the county of Providence and State of Rhode Island, have invented a new and useful Improvementin Bearings for Spindles of Spinning-lllaehines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings,forming part of this specification, in which- Figure l is acentral vertical sectional view of the bolster, bolster-ease, and whirl, the spindle and supporting-pinbeing exposed in side elevation. Fig. 2 is a side view of the bolster. Fig. 3 is an enlarged view in vertical section of the upper end of the bolster and its case, showing the application of the cap to prevent the bolster from turning, and showing a portion of the spindle-'in side elevation. Fig. 4c is a detail side view of the cap, and Fig. 5 is a plan view of the cover to the oil-chamber in the bolster-case. Fig. 6 is a vertical section of the lower portion of the bolster-case, with the lower end of the bolster and spindle in side elevation, and showing a modification of my invention.
In a previous application for a patent, led July 3, 1882, I have described a means for reducin g the friction, noise, and power required for driving spinning-spindles, for which purpose the spinning -spindle bolster was suspended in the bolster-case by means of atlange or shoulder, so as to have a free lateral niotion, and said bolster had a plain cylindrical surface in the plane of the whirl," looselytted in the bolster-case, so that a cushion of oil existed between the bolster and bolster-case, securing the results before described.
The object of myp'resent invention is mainly to secure or make available'these same advantages in such forms of spinning-bolsters already in use which do not have a flange for supporting them in their cases; and to this end my invention consists in combining, with the bolster and bolster-case, a ball or a detachable stiff vertical supporting-pin having free lateral movement, which pin or ball is stepped at its lower end in the bottom of the bolsterease, and upon which pin or ball, at its upper end, the bolster is stepped and supported, but
has a free lateral movement, while the oilcushion between the bolster-ease and the bolster is preserved in the plane of the whirl, as. in my previous application referred to.
My invention also consists in means for lock- 5 5 ing the bolster and its case togetherto prevent the former from turning, and iu the means for facilitating the lubrication ofthe parts, as will be hereinafter fully described.
In the drawings, B represents the pin, rest- 6o ing upon its end in the bottoni of bolstercase O, and forming a support for thelooselyiitted bolster A. Thispin is free to inove sidewise at its upper end, and also has considerable length, which allows its load to be moved 65 quite readily as the oscillations of the bolster require. Inside the bolster isl arranged the spindle S, having the usual whirl, and in the plane of this whirl the bolster has a loose cylindrical tting to form an oil-cushion, as de- 7o scribed in my application referredA to. Now, to prevent the bolster from turning in the bolster-ease, I use a metal cap, D, that is forced within the Lipper end of the bolster-case with a frictional contact down to a shoulder formed 7 5 upon the metal cap. Upon one side of this metal cap D there are two slits made, andthe metal between the two slits is forced into for1n` a key or steady-pin, b. (See Figs. 3 and 4.) This fits within a somewhat larger slot, (t, that 8c is cut outof the upper end of bolster A, (see Figs. 2 and 5,) and by this means Ivery readily keep the bolster from turning. The lower portion of the bolster-case is formed iu the nature of an eXteriorly-threaded socket for S 5 connection with the rail by a nut, as usual, and above it is a chanibered space about the central stem, marked E. This is for a reservoir to hold oil for lubricating. From bottoni of reservoir there is a hole, F7 drilled diago- 90 nally through the bolster-case to the interior space. To permit the oil to iill the interior space for the purpose of lubricating the spindle and cushioning the bolster, I use a metal cover, G, that is loosely fit-ted within a recess 95 at the upper end of oil-space E, and this metal cover is made with an inside diameter at its upper end that is larger than the upright stem of the bolster-case which it surrounds. By having this open space it permits any oil that :too
may overllow l'roin the top of bolster to return again to the oil-reservoir for the use of lubriea-tion again. This disk or metal cover Ghas one or more holes through its lower surface, near its outer diameter', for the purpose of supplying the reservoir with oil, a great advantage in the saine being that the spindle can be'supplied with oil when it is in ruiming motion.
In defining inyinvention with greater elearness, I would state that I ani aware that a bolster has been sustained inside the bolster-ease upon a springing or elastie stein which was rigidly iiXed to the bolster; and I do not elaiin this, but only a stiil" or inflexible laterallytilting pin or shafthaving a loose frietional abutment against the bolster; or in the plaee thereof a ball which takes the place of the pin and rests upon a flat surfaeein the bottoni Aof the bolster-ease, as shown at B in Fig. G,
so as to have a free lateral motion, the said ball sustaining on its upper side the bolster just as the pin does.
Having thus described iny invention, what I l. The combination, with the b0lster-ease, the spindle, and the bolster having a loose peripheral iitting throughout its length in the ease, forming an oil-chamber, of an inflexible supporting-pin, B, or its equivalent, as deseribed,.the same being supportedin the lower end of the ease, and having a loose -frietional abutment against the bolster at its point of Contact therewith, to support the bolster and allow it free lateral adjustment, as described. 2. The combination of the bolster A, hav ing noteh a, the bolster-ease, and the cap D, having tongue or key Z), the said eap being litted with a frietional eontaet upon the' bolster-ease, with its tongue Z) projecting into the slot a, to prevent the bolster from turning, as described.
