JOHN SUTTON, OF

NEN YORK, N. Y.

SELF-FEEDING ATMOSPHERIC LUBRICATOR.

Specification of Letters Patent No.

To all whom 'it may concern:

Be it known that I, JOHN SUTTON, of New York, in the county of New York and State of New York, have invented a new and improved mode of constructing a selffeeding atmospheric oil-cup for lubricating journals of shafts, crank-pins, guides, and, in fact, all working joints of every description of machinery requiring lubrication, the object being to economize the oil and keep the part well and regularly supplied during the time it is in motion, it being so regulated thatby the revolution of the journal the oil will be drawn to the same from the reservoir, and by the inaction of the journal or other part the oil will stop flowing; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this speciiication, in which the figure is in part perspective and in part a transverse view.

A, is the oil reservoir made of any suitable material, shape or size, which with its tube a, and shank Z9, and part cover b, may be made or cast in one piece, or separately and jointed as required, or the reservoir A, and part cover may be cast with the pillar block z', and the tube a, and Z), inserted and its regulating cap attached as may be required, the tube a, standing within the reservoir A, being for the purpose of preventing the sediment going to t-he working part. The lower extremity of the tube or shank 7J, may be continued down and screwed into the brass box y', in red lines, thus conveying all the oil to the part, or it may be connected as required to the pillar block cap z', yet in this case much oil is lost by escaping between the cap and box j.

c, is the opening or neck-of the reservoir A, for receiving the oil.

f, is a channel cut outside of the neck c, in the part cover b', of reservoir for catching any surplus drops when filling (yet this is not really essential). Vhen it is necessary to make the reservoir for large journals Src., with compartments, it may have one or more regulating caps, also one or more tubes or Shanks.

B, O, D, is the combined regulating arrangement, B, serving as the cover of the reservoir A. Within its underside is an elastic washer d, securely tted 1n, having 13,769', dated November 6, 1855.

a passage e, cut in its center, also through the cover B, to the space E, for air. Into the upperside or top of cover B, is a vertical threaded chamber into which is loosely inserted the regulating plug D, having a space E, under it for receiving any suitable porous and elastic substance fitted in loosely which on being compressed by screwing down the plug D, will diminish the passage of the air to the reservoir A, and by a reversion of the plug D, will enlarge the same so that being graduated to suit it cannot admit more or less air to t-he reservoir than it is required to, which air passes through the passages e, e,- porous substance &c., and fills the vacuum that is made as the oil is drawn from the reservoir A, by the working of the part under it.

O, is a dome or guard screwed to the top of the cover B, for preventing any injury to or displacement of the regulating plug D.

e, is a small passage in the dome from the atmosphere to its interior for the admission of air a suliiciency finding its way between the threads of the plug D, &c., to the space E, or substance, or if requisite the plug D, may be drilled or channeled. If required, .as it may be in some cases, the plug D, may be dispensed with and the top of cover B, made solid, having the passage e, continued to the top of same between which and the underside of the dome C, may be placed the porous and elastic body the quantity of air through which may be regulated by tightening and slackening the dome as shown by the plug D.

Mode of operating: Determine the number of drops of oil required per day for the part, select a feeder holding that quantity, put a washer g, on the shank end and attach it to the brass box-bush or other part, so that it shall be a Xed air tight joint, see that t-he cap B, has its elastic washer d, remove the dome O, and regulating plug D. In the space E, place a flat circular piece of gutta percha, cork, or rubber, having cut a small channel across its under face. rlhen put in loosely circular pieces of cloth above it, screw down the regulating plug D, tightly with the fingers, fill the reservoir through the neck c, with oil, put on the cap B, &c., as now combined, screwing it tightly with the lingers. Now should it feed too much tighten the plug D, more, thus shutting off the air or slacken it if not feeding enough until it delivers to suit,

when the dome C, may be screwed to its seat as it is no w in working order. It will be necessary to fill this cup but once per day and so regulate it that at the end of the working time it will have delivered all its oil. Yet in many cases when there is a quick revolution of the journal in the direction of the arrow 7c, this apparat-us being attached as shown in the drawing having its regulating plug screwed down just enough to prevent the oil dropping. Then the journal is still it may be seen that the oil (in the passage L, and channel zf, cut in the brass boX, and resting on the journal) will be drawn from the reservoir A, as the shaft revolves, thereby creating a vacuum in the reservoir which is filled by the atmosphere passing through the passages, &c., to the reservoir so that when t-he machine is not working should there be any oil in the reservoir it cannot escape until again drawn upon by the working of the part. For ocean Steamers for certain parts t-he reservoir may be constructed to hold and feed suflicient for the passage.

I am aware of there being in use self feeding oil cups for lubricating journals, &c., of machinery, having working buckets or valves, within the reservoir, with outside connections operated by the shaft. I am also aware there are others of the valve under the reservoir, and working in the oil, the objection to all of which is their complication and liability of derangement, and irregularity in feeding, by the valves, plugs, &c., becoming corroded or gummed.

W'hat I claim as my invention and desire to secure by Letters Patent is- An arrangement of means constructed on or within the cap or cover B, (of the reservoir co-ntaining the oil or other lubricating material) sufficiently distant from the oil to never be in contact with the same, by

the adjusting of which, the passage or passages leadmg from the reservoir to the atmosphere may be entirely or partially openedor closed, at will, thus causing an plug D, and the substance in the space E,

as a hollow, or other plugv or equivalents may be used to produce the same effect, either of which, may be used as the part whenplaced may permit, and without al` tering the principle or mode of feeding herein described.
