RICHARD KITSON, CF LOWELL, MASSACHUSETTS.

Specification forming part of Letters Patent No. 116,S40, dated July 11, 1871.

To all whom it may concern:

Be it known that I, RICHARD KrrsoN, of Lowell, inthe county oi' Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Feed-Regulators or Eveners for Cotton-Lappers, of which the followin g is a full, clear, and exact description, reference being had to the accompanying drawing making p art of this speciiication, in which- Figure 1 represents a sectional elevation; Fig. 2, a plan or top view. Figs. 3 and/1 are detached details pertaining to the saine, Fig. 3 being a cross-section through tl'lerworm-gcar shaft, and Fig. 4 a bottom side view ofthe latter.

This invention relates to the construction of the slide A and the arrangement of the rockingboX B, which supports the upper end of the cone and the worm-shaft C, to the hub (I, which 4rises in and above the oil-chamber or trough I) to prevent the lubricating material in said chamber passing down the coneshaft. In the ordinary feed-regulator slide the rockin g-box B is arranged in the top of the slide, and the oil in the chamber D lubricates the top of the cone-shaft, and most of the oil is wasted by ruiming' down onto the cone, soaking or saturating the belt and other parts of the machinery. The oil in the chamber D is intended to be carried upward by the rotary motion of the gear E to lubricate its teeth and the screw-threa ds of the worm F runnin g together. .The supply of oil carried up by the gear, being very abundant, runs immediately back down the worm and its hub into the oil-chamber, to be again or constantly carried up, and all the time running back into the chamber, and, in consequence of a constant leakage around the worm and cone-shaft, large quantities of oil are con sumed or wasted. To overcome this difficulty I construct the slide with a hub, d, rising in and above the oil-chamber, and a recess, g, in the under side of the slide; and in this recess I hang the rocking-box B by pivots or trunnions c projecting from opposite sides, all substantially as shown in the drawing.

It will be understood that the gear E is on the feed-roll, the motion of which is controlled by the action of the worm operated by the cones G and H and a belt running around them. It is alsounderstood that as often as a lap of suitable weight or other dimensions is formed by the lap-forming machinery the connecting mechanisms detach or liberate the feeding mechanism, and throw the worm F out of contact with the teeth ofthe gear E, and this stops the feed while the fully-formed lap is removed and an empty lap-roll placed in the machine. The feed-connecting mechanisms are then operated either by hand or automatically, which brings the worm into operatin g contact with the gea-r E, when the machine resumes its feeding and lap-forming operation. In Fig. 2 I have shown the usual pivoted plate K, which operates the slide engaging with the latter between two rising hubs, c, connected therendth. The plate K is operated to move the slide by means of a lever,

f, passing through a slot Vin the top of the case,

as in the common feed-regulator. In practice I recess the lower end of the worm-hub, so as to cap the hub rising in the oil-chamber, and this conducts the oil which flows down the worm-hub directly into the trough and keeps it away from the upper cone-shaft bearing, whieh'should be lubricated with oil from some other directionthat is, by a separate oil-hole leading through the side of the rockingbox, or through the slide above it. The bearings ofthe rocking-box B may be formed in the sidesof the recess g, Iand secured by caps a. and screws, as shown in Fig. 4. The hub d may be cast with the slide, or tightly fitted and fastened, so as to prevent leakage of oil around it.

I claim as my invention- 1. The slideA, constructed, as described, with an under recess, y, and a rising hub, d, in and above the oil-chamber, in the manner and for the purpose speciiied.

2. In combination with the slide constructed with the under recess, as described, the rockingbox B, arranged in the manner and for the purpose set forth.
