NITED STATES PATENT OFFICE.

EDWIN HITCHON, OF ACORINGTON, ENGLAND.

SPINDLE-SUPPORT.

SPECIFICATION forming part of Letters Patent No. 554,514, dated February 11, 1896.

Application filed August 15,1895- Serial No. 559,359. (No model.) Patented in England July 25,1894=,N0-14,261.

T0 aZZ whom it may concern:

Be itknown that I, EDWIN HITCHON, a subject of the Queen of Great Britain, and a resident of Accrington,in the county of Lancaster, England, have invented a certain new and useful Improvement in Spindle-Supports, (for which I have obtained British Letters Patent numbered 14,261, dated July 25, 1894,) of which the following is a specification.

My present invention is an improvement upon the spindle-support which is the subject of my United States Patent No. 530,073. In that patent I have shown, described, and claimed a combination of instrumentalities among which is a cross-bearing on the bolster base or flange and tangential to the bolster for receiving a rock-shaft having at one end an arm which carries a cover for the oil-tube and at or near the other end an arm which carries a spindle-holder, the rock-shaft being held in position to cause the device carried by it to cover the oil-tube and to hold the spindle by a counterweight or its equivalent, such as a spring. In the embodiment of my invention shown in said patent the crossbearing is a continuous unbroken tube, the combined holder-cover and rock-shaft is of wire, and this wire must be partly bent into its ultimate shape after the shaft portion of the wire has been inserted into shape.

By my present improvement I am enabled to make the device (except of course the cross-bearing) in a single casting and to bring it into finished shape before placing it in position on the spindle-bolster.

The nature of the improvement can best be explained and understood by reference to the accompanying drawings which will first be described, after which the improvement will be more particularly pointed out in the claim.

In the drawings, Figure 1 is an elevation from the side of the spindle-bolster on which the oil-tube is located, with the rock-shaft and its attached parts removed. Fig. 2 is a like View with the rock-shaft and its detached parts in place. Fig. 3 is an elevation from the side on which the cross-bearing is located. Fig. 4 is a plan. Fig. 5 is a view of the rockshaft and its attached parts.

A is the spindle; B, the bolster; G, the upright oil tube; 0, the horizontal branch thereof which puts the oil-tube in communication with the bolster; D, the cross-bearing for the rock-shaft formed on the bolster base or flange and tangential to the bolster; a, the rock-shaft; b, the oil-tube cover; 0, the upright carrier-arm for said cover; 6, the spindle-holder; d, the upright carrier-arm for said holder, and f the counterweight. These parts in their general combination and arrangement resemble the corresponding parts in my patented device hereinbefore referred to and are distinguished by the same reference letters.

In the tubular cross-bearing D is formed a longitudinal slot or opening g, which extends from end to end of the bearing. This permits the rock-shaft with its attached parts to be readily placed in position by inserting the shaft endwise into the bearing with the coverarm 0 foremost and traveling along through the slot 9 until that arm passes out from the slot beyond the far end of the bearing D. Then if the rock-shaft be released, its counterweight will turn it in a direction to cause the cover I) to close the oil-tube and the holder 6 to overhang the spindle-wharve, by which movement the arm a will be carried out of register with the slot g. The same movement carries the holder-arm cl also out of register with the slot, although in fact that is hardly necessary, inasmuch as this arm, as shown, is thicker than the width of the slot, so that it could not in any event pass therethrough. The cover-arm c is on the contrary made thin at its base so that it will pass easily through the slot. The distance between the two arms a dis about equal to the length of cross-bearing D, so that after the rock-shaft has been inserted in the bearing a distance sufficient to bring the cover-arm 0 just beyond the far end of that hearing and then has rocked to throw its arms (I 0 forward or toward the spin dle and oil-tube said shaft will be locked firmly against endwise movement by its arms 0 d, which lie at and against opposite ends of the cross-bearing. The slot 9 is formed along such a line relatively to the arms d and c that they can be rocked back far enough to uncover the oil-tube and release the spindle without bringing the arm a into register with the slot. In other words, to bring the arm 0 into register with the slot g it must be rocked backward to an extent considerably-in excess of the movement by which the oil-tube is uncovered. Thus under all normal conditions the rock-shaft will be restrained from lengthwise movement and the cover and holder consequently will be maintained in proper position, while at the same time the shaft and its attached parts can instantly be removed whenever occasion requires it. I am also enabled to make the rock-shaft and its attached device, whether a casting or not, into finished shape before fitting the same to the crossbearing.

As provided in my aforesaid patent, I may use a spring instead of a counterweight, and I desire to be understood as including any such substitution in my claim.

What I claim, and desire to secure by Letters Patent, as an improvement upon the spindle-support which is the subject of my Letters Patent No. 530,073, dated November 27, 189i, is-

The combination with the spindle, bolster and oil-tube of the cross-bearing on the bolster base or flange tangential to the bolster provided with the longitudinal slot g extending from end to end of the bearing, and the cross-shaft, the oil-tube cover and spindle holder and the two carrier-arms for said cover and holder, said arms when in operative position being at opposite ends of the cross-bearin g and out of register with the slot thereinand the slot being so located with reference to the arms, that the cross-shaft carrying the latter can be rocked back far enough to uncover the oil-tube and release the spindle without bringing said arms into register with the slot as hereinbefore shown and described.

In testimony whereof I have hereunto set my hand this 1st day of August, 1895.
