WALTER A. CHANDLER, OF LOWELL, ASSIGNOR TO GEORGE DRAPER & SONS, OF HOPEDALE, MASSACHUSETTS.
SPINDLE.
SPECIFICATION forming part of Letters Patent No. 498,952, dated J une 6, 1893.
Application tiled December 17l 1891. Serial No. L115,327. (No model.)
To all whom it may concern.-
Be it known that I, WALTER A. CHANDLER, of the city of Lowell, in the county of Middlesex, in the State of Massachusetts, have invented a certain new and useful Improvement in spindles; and I declare the following to be a specification thereof, reference being had to the accompanying drawings.
Like letters indicate like parts.
Figure 1 is a View of my invention, partly in side elevation and partly in central, vertical section, the spindle being shown supported by the bolster and on the adjustable step. Fig. 2 is a side elevation of myimproved bolster in engagement with the adjust-able step. Fig. 3 is a View of the bolster casing in central, vertical section, with the bolster and step in side elevation, within said casing, but not in engagement with each other. Fig. tis a cross section on line 4, 4, of Fig. l. Fig. 5 is a cross section on line a: of Fig. l. Fig. 6 is an elevation of the spring pin.
My invention relates to the general class of spindles and more especially to the bolsters and steps thereof.
It consists of the combination with a spindle, of an adjustable step, having a square head and ascrew-threaded stem, the latter being engageable witha central screw-threaded bore at the bottom of the oil chamber, within the casing; a bolster, having a tapering bore and a shoulder which rest-s upon a shoulder within the casing and provided with a locking portion, hexagonal in cross section, with plane faces to lie in contact with similarly disposed plane faces in the bore of the casing, and also having at its lower end a square opening, adapted to receive the head of the adjustable step, as hereinafter particularly specified.
In the drawings A represents the spindle, of tapering form. The foot of the spindle is shown at a and the whirl at b. The casing B has the central, tubular bore c, extending far enough to receive the bolster, which bore terminates with the oil chamber d. The oil chamber d is tubular, but has aless diameter than the bore o, so as to leave a shoulder e. At the bottom of the oil chamber d, is a small, central bore f extending down into the solid portion of the casing B and provided with a screw-thread.
D is the oil cup with ducts g leading therefrom to the bore c of the casing B.
C is a spring pin having a screw-threaded end, by which it is secured to the bolster casing. The pin is made of tempered metal and is flattened, so as to easily bend, and at its upper end has a bent end e, bent angularly, as shown. The pin C serves to prevent the rise of the spindle from the bolster by extending its head over the whirl.
The bolster E is cylindrical upon its outer surface to fit the bore c of the casing B, and tubular to receive the spindle A. The bore of the bolster is tapered, as shown in Fig. 1, to adapt it to the taper of the spindle. The bolster has the oil ducts h and its exterior surface is cut away sufficiently to receive the fibrous or woven sleeve F, which is to be saturated with oil. Near its bottom, the bolster is provided with a circumferential shoulder m and also with a locking portion, integral therewith, shown at n, with plane exterior faces, hexagonally disposed, and terminates with a cylindrical portion o. The bore of the bolster at its lower part is made square in cross section, as seen in Fig. 4.
The step has a square head p and a cylindrical screw-threaded stem or shank q, which engages the bore f of the casing B.
The spindle A is supported byits tapering sides resting against the tapering bore of the bolster and also by the foot a, resting on the top of the head p of the step. By its continuous and rapid revolution, it becomes worn, and some device is necessary in order to adjust it to compensate for such wear. This I accomplish by making the step, upon which its foot rests, adjustable in a vertical direction. This step by means of its screw-threaded` stem q, which enters the screw-threaded bore f of the casing B, is capable of a vertical adjustment to the required degree, when turned upon the screw threads. ing of the step is eected by the rotation of the bolster by hand. As the lower portion of the bore of the bolster is made square in cross section, it serves as a key and receives the square head p of the step and turns the step,
This turn- IOO while at the same time it is to some extent movable longitudinally on the head p.
The portion of the bore c of the casing B, commencing at the shoulder@ and extending downward to a distance equal to the length of the portion n of the bolster E, has plane sides, hexagonally disposed, which, when in Contact with the surfaces of the portion n, form locking faces, as seen in cross section in Fig. 5. To adjust the bolster, it should be lifted by hand sufficiently to bring the locking faces n up out of the hexagonal portion s of the bore c of the casing, into the tubular portion of said bore. It is now free to rotate, but as it has not been lifted off the head p of the step, said step rotates with it. It is turned as far as necessary for the desired adjusty ment and thereby raises or lowers (as the case may be), the step, by the engagement of the screw threads of theparts q f, and, when correctly adjusted, the bolster is pressed down again by hand and the plane faces again are locked, but in a new position, while the head p of the. step is received deeper or lower down, or farther up (as the case may be), in the bore of the bolster, as required for the adj ustment. If the step -is screwed lower down into the casing, the spindle descends farther into the bore of thebolster and lits moresnugly; while, if the stepfis unscrewed, it rises and the spindle is looser in the bolster.
Ihave specified and shown the faces of thepart n of the bolster and the corresponding recess-'ain the bore c as hexagonal., They may,ho`wever, be square, octagonal, or have any number of angularly disposed vertical' faces. I prefer, however, the six faces shown, and by means of these, I can YVerticall y adjust the step to an extent equal to one sixth of the distance determined by the pitch o f the but by this movement I have also altered thev h eight of the step by one sixth of a revolutlon of the screw shank q, but'without disengaging the head p o f the step from the bolster The construction shown furnishesa superior locking mechanism which iseasily operated; `gives an independent support to the bolster', aswell as to the step,and admits of a finer vertical adjustment than has heretofore been practicable. The oil chamber is of greater capacity than usual, and is free from all liability of leakage, as it is not tapped from the outside for any rivets or locking pins, as in some of the well-known devices. The step is cheaply made from bar metal, with the shank turned'for a screw, while the bolster and case have only central bores and apertures. As the bolster rests upon its shoulder and projects therefrom below, it yields to the vibration of the spindle in every direction without hinderance.
I claim as a-novel and useful invention and desire to secure vby Letters Patentl. In combination with a bolster casing, having a screwfthreaded bore, a rotatable step, having a head `with angularlydisposed plane faces and a screw-threadedstem to engage with said bore, andarotatable bolster mount-- ed in said casing and having an opening at its lower end adapted to receive vthe head of the step and to lturn the step, substantially as Iauditor the purpose-specified.
2. Thecombination of the bolster casing B,
`having the bore c, the screw-threaded bore f .and the recess` s with angularly disposed lplane sides, the rotatable stephaving the head p with angularly disposed' plane; faces and the screwfthreaded stem q, the rotatable bolster E mounted in the borec of the casing .B and having an opening` atv its lower end iadaptedtoreceive the head p andto turn the step, and alsov having -thelockingrportion n with corresponding langularly disposed plane faces to enterA said recess s, substantially as and for the purpose specified.
3. In combination with a spindle and'bolster-case, an Yadj ustable lstep provided with a .head and a bolster having at itslower enda .device adapted to engage said head, substantially as and for the purpose specied.
