SPINDLE BEARING OR SUPPORT.v

SPECIFICATION forming part of Letters Patent No. 577,553, dated February 23, 1897.

Application led October Z2, 1896. Serial No. 609,651. (No model.)

To all whom it mag/concern.-

Be it known that I7 WILLIAM HINCIILIFFE, of Huntsville, in the county of Madison and State of Alabama, have invented an Improvement in Spindle Bearings or Supports, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object to support the step for a spindle in a novel manner.

In my invention I employ a loose bolster, and to enable the foot of the spindle to have greater freedom of motion than it could have due to the movement of the bolster alone I have made the step separate from the bolster and have suspended it from the lower end of the bolster, so that it may swing in the space lin the bolster-case below the lower end of the bolster, the swinging connection referred to being effected by a bale or loop in which the step is set.

My invention consists, essentially,in a spindle supporting case, containing a loosely-supported bolster and a step sustained below said bolster by a loop or stirrup, as will be described.

Figure 1,in section,represents part of a spindle and its bearings embodying my invention. Fig. 2 shows the bolster and its connected step removed. Fig. 3 shows the lower end of the bolster. Fig. 4 shows the step detached. Fig. 5 shows one form of loop. Fig. 6 shows amodiied form of loop, and Fig. 7 the lower end of abolster to be engaged by it.

The supporting-case A, adapted in practice to sit on a rail, as usual, has an internal bore provided with a shoulder co, on which rests the shoulder of a bolster b, entering said bore loosely and adapted to move laterally on said shoulder ct in said bore. The bolster is provided with a groove b', which may be entered 'by a suitable pin or projection b2 to restrain the rotation of the bolster in the case. The spindle c, of any usual or suitable construction, enters the bolster, and its foot extends below said bolster, and in this my invention this foot enters a step d, which sits in a loop or stirrup d', said loop or stirrup suspending 5o the said step below the bolster in the bottom of the space d2 of the case, the loop forming a yielding connection and support for said step.

In Figs. 1 to 5 this loop is shown as having projections 2, which enter external cross-slots 3, made across the exterior of the bolster near its lower end, other intersecting vertical slots 4 receiving the vertical sides of the loop.

The link shown in Figs. 1 to 5 works very satisfactorily, yet this invention is not limited to the exact shape or construction shown for said loop, as, for instance, it may have the ends of its arms bent inwardly at 6,Fig. 6,

and enter holes 7, made in the bolster, as

said case below the said bolster by a loop,sub

stantially as described.

2. The bolster-case, a shouldered bolster mounted therein loosely and a step, combined with a loop connected to and suspended below the lower end of said bolster, said loop wholly supporting said step in the said bore loosely, whereby the foot of the spindle and its step are permitted freedom of motion,sub stantially as described.

3. A spindle, a bolster-case, and the bolster sustained loosely therein, combined with a loop having its ends bent to enter notches in the bolster, and a step sustained by said loop, and receiving the foot of the spindle, substantially as described.

In testimony whereof I have signed my name to this specication in the presence of two subscribing witnesses.

WILLIAM IIINCHLIFFE. Witnesses:

D. L. DAwsoN, WALTER VINsoN.
