IMPROVEMENT IN SPlNDLE-STEPS FOR SPINNING-FRAMES.

Specification forming part of Letters Patent No. 184,742, dated November 28, 1876; application filed February 16, 1 876.

invented certain new and useful Improve-- ments relating to Spindle-Steps for Cotton- Spinning Frames, of which the following is a specification 1 The intense velocities impressed on spindles, and the necessity for plentiful lubrication, have induced various refinements in the steps or provisions for supporting and steadying the foot of each spindle. Among them has become in a degree standard the plan of inserting into the substantial rail a vertical cylinder of cast-iron, containing a lining or bushing of brass, with some provisions for receiving oil at the top.

Our improved step belongs to this class. We enlarge the cast-iron cylinder above the rail, and provide thereby a capacious receptacle for oil; provide a removable cover for the exclusion of dirt; construct the parts so that, on elevating the cover, the oil in the receptacle is plainly exposed to view, and arrest any whirling motion of the oil which might be received from the spindle, by providing fixed stops close to the spindle, which allow a sufficiently free access of oil, but prevent any whirling motion being imparted to the mass. We prefer to construct these stops by extending the bushing upward to, or a little above, the highest proper level of the oil, and provide limited spaces for the access of the oil to the spindle, by sawing across the bushing at its upper end.

However the stops to prevent a whirling motion of the oil may be arranged, We extend upward the bushing in the solid or undivided condition a little above the. top of the cast-iron cylinderor, in other words, a little above the bottom of the oil-vessel. This prevents the very bottom portions of the oil from finding access to the-spindle, and forms a space in which any dregs or heavy particles in the oil may settle and accumulate. An

occasional wiping out of the bottom of the oil-vessel and refilling of the receptacle with clear oil insure the efficient lubrication, and prevent any access of grit to the spindle for an indefinite period.

The accompanying drawings form a part of this specification, and represent what we consider the best means of carrying out the invention.

Figure 1 is a side elevation of the spindle with the other parts in section, and Fig. 2 a horizontal section.

Similar letters of reference indicate like parts in both the figures.

G is a stationary rail. A is a cylinder of iron, held firmly in a hole in the rail G by means of a pinching-screw. M is the oil-receptacle, formed by an annular enlargement, A and a cylindrical rim or circular wall, A, both formed in the same casting with the cylinder A. B is a brass bushing, fitted in the part A, and extending up a considerable distance in the oil-vessel M, as represented. Its upper part is divided by a saw-kerf, b. The parts of the bushing thus divided, and which project upward in close proximity to the spindle D, we will denominate B. They serve asa stop to prevent the mass of oil outside from receiving a whirling motion from the rotation of the spindle. O is a movable cover, surrounding the spindle and matching over the exterior of the oil-vessel.

The coverO may be lifted by the thumb and finger of the attendant, and the interior of'the oil-vessel is thus fully exposed to view. Inspection determines instantly whether or not there is a liberal supply of oil remaining in the vessel, and on introducing more oil the eye observes easily the rate at which it bev comes filled.

The advantages of having a liberal supply of oil around the spindle have been long appreciated. Ordinarily, the whirling motion imparted thereto is liable to throw out the oil unless there is an internal flange on top of the interior of such vessels, however high the stops B, with the spindle D and vessel M, as cover is lifted; and when, the nose of an oiler specified.

is introduced and oil is applied, it is liable to In testimony whereof We have hereunto set' be supplied in excess, and to overflow and be our hands this 11th day of February, 1876, in wasted before the attendant can be aware that the presence of two subscribing witnesses.
