XVILLIAM T. CARROLL, OF \VOROESIER, ASSIGNOB TO GEORGE DRAPER & SONS, OF HOPEDALE, MASSACHUSETTS.

SUPPORT FOR SPINNING-SPINDLES.

SPECIFICATION forming part of Letters Patent No. 360,277, dated March 29, 1887.

Application filed December 10, 1886. Serial Xn. 221,207.

To aZZ whom, it may concern:

Be it known that I,W1LLI AM T. CARROLL, of Worcester, county of \Vorcester, and State of Massachusetts, have invented an Improvement in Supports for Spinning-Spindles, of which thefollowing description, in connection with the accompanying drawings, is a specifieatiou, like letters on the drawings representing like parts.

Prior to my invention bolsters for supporting spindles having but a single lateral hearing, and that at the lower end, have been held in a yielding manner by being surrounded by a fibrous or elastic packing, and also by oil; and so, also, the shank of a bolster extended into a hole in a bolster-rail has been surrounded by an elastic packing.

All that part of my improved bolster above the rail is in one solid piece; but to enable the bolster to yield sufficiently to compensate for jar or vibration of the spindle, owing to an unequal load, I have provided the bolster with a tubular or skeleton shank which receives within it an elastic packing or cone, which is compressed as the bolster, moved by the strain of the spindle within it, is moved on or with relation to the rail.

My invention consists, essentially, in a bolster composed of a sleeve to receive the pin tle of the spindle, and having a sectional or divided stem, combined with an elastic packing or cone applied to the interior of the said stem, substantially as will be described.

Figure 1 in vertical section represents a rail, a bolster, a packing, and sleeve whirl, the spindle being in elevation. Fig. 2 shows the bolster and part of its shank detached or separated, and Fig. 3 is a section of Fig. 1 below the bolster-rail in the line 00 :v.

The bolster-rail A and spindle B, having a sleeve-whirl, B, are all as usual. The bolster 0 above the rail presents a sleeve bored cen- (No model.)

trally for the reception of the pintle or lower end of the spindle. The shank of the bolster, reduced below the shoulder, 2 to enter a hole in the bolster-rail, is made in sections or divided to form, as herein shown, two parts, (1 d, the part 11 being fast to the sleeve, while the other part is loose. Between these two parts (I d, I have inserted an elastic packing or cone, o herein shown as a roll or plug, (2 preferably of india-rubber, of such size as to fully fill the space between the parts (I d, the said roll or plug acting to keep the two parts of the shank pressed outward against the interior of the opening in the ring-rail, but permitting the shank of the bolster to move and compress the said roll or plug d as the bolster is subjected to slight vibration or movement by means of the strain of the spindle within it, the spindle being unevenly loaded and run rapidly.

The roll or plug might be of leather or fibrous material, or of any compound employed as a substitute for leather or india-rubber, or of cork or wire or other compressible material. In the present instance of my invention the bolster is kept from being lifted from the bol ster-rail by a pin or bolt, 6.

I claim- A bolster composed of a pintle-receiving sleeve having a sectional or divided shank, combined with an elastic or compressible packing or cone filled into the spacebetween the parts of the sectional or divided shank, to operate substantially as described.

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

WILLIAM T. CARROLL.
