OILERQ SPECIFICATION forming part of Letters Patent No 296,047, dated April 1, 188- Application filed February 6, 1884. (N0 model.)

Be it known that I, JOHN S. PARK, of Rockport, in the county of Spencer and State of Indiana, have invented a new and Improved Oiler, of which the following is a full, clear, and exact description.

The object of my invention is to provide a simple, inexpensive, and effective device for oiling the crosshead guides of steam-engines, more particularly; but the invention is applicable also to oiling the guides of other reciprocating parts of machinery.

The invention consists in an oiler having pivoted oiling-heads carrying oil cups or reservoirs, and a weighted stem to throw the oil: ing and wiping heads into contact with the friction-surfaces of the cross-head guides by the inertia and momentum of the parts on reversal of the motion at the limit of the stroke of the cross-head in either direction.

The invention consists, also, in certaindetails of construction and combinations of parts of the device to adapt it to serve either with single or double cross-head guides, all as here inafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate cor responding parts in all the figures.

Figurel is a side elevation of my improvement as applied to the single-bar cross-head guide of alocomotive stearn-engine. Fig. 2 is a plan view of the same in part; and Fig. 3 is y a side elevation, partly broken away, of a modification' of the improvement, and as applied to a double parallelbar cross-head guide.

, Referring first to Figs. 1 and 2 of the draw ings, A is thecross-head; B, the bar or guide on which the cross-headtravels back and forth. G is thepiston-rod connecting the cross-head with the piston in the cylinder D, and Eis the connecting-rod leading to the engine-crank. All these parts may have any approved construction.

On any suitable base-plate, F, I fix three standards or posts, G G G, G being the (zen-- ter post, to which is pivoted the head H, which has a segment of gear-teeth, h, at each end, and a central stem, H, fixed at right angles to the head .11, and carrying a weight, H which preferably is adjustable along the stem, and may be held, when adj usted, by a set-screw, c.

On each side post, G, I pivot at 9 an arm, I,

which carries at one end a segn'lentplate, I,

having gear-teeth z, meshing with the teeth h of the head H, and at the outside downwardlybent portion of the arm I is fined a plate, J, having a wiper or cushion, j, of any suitable soft fabric.-such as sponge, felt, &e.secured to its under side, to receive and distribute over the face of the guide B the oil fedlto it through a passage in the plate J from an oil-cup, K, of any suitable kind, carried on the back of the plate. The gears h t are interxneshed, so that a rocking of the weighted stem H to either side of a vertical line will raise one ofthe oiling-heads J j from and lower the opposite one to the guide-bar B.

In operation, as the cross-head A moves inward toward the cylinder D, the stem H will lie over to the left of a vertical line, and the right-hand oilerhead J j will bear on the guide B in advance of the cross-head A or its brass a, and after completion of the inward stroke, and on reversing for the outward movement, the inertia of the weighted stein H, together with the forward momentum of the cross-head in its outward stroke, will cause the stem H to shift over quickly to the right of the vertical line and lift the inward oiler-head J j and lower the outer head J j upon the guide B and in advance of the moving cross-head,which are the positions of the parts shown in the drawings. At the extreme limit of the outward stroke, and on reversal for the inward stroke, the stem H will be shifted to the left, and the right-hand oiler will bear on the guide B in front of the cross-head, as first described, and these operations will be continued with the travel of the cross-head, the opposite heads 0 J j bearing always on the guide B in advance of the cross-head. The oiling-heads not only feed oil to the upper face of the guide, but act also-to wipe from it any dust or grit, which would, if not removed, unduly wear the fric- 5 tion-surfaces. a

I have shownthe oiler base-plate F slotted at f, so as to pass beneath the heads of the nuts d, used to fasten the top brass, a, and take up the wear of the brasses; but the oiler may be held to the cross-head in any other suitable manner. I

In the modification shown in Fig. 3, in which I apply the same principle of rocking the opposite oiling-heads into contact with the guide-bars by the inertia and momentum of the parts on the reversals of stroke of the cross-head, I pivot to both sides of the crosshead A a four-armed or suitable head, G

made hollow to communicate with an oil-cup,

K held thereon, and deliver the oil from the cup and through opposite hollow arms or tubes 1 to perforated oiling-heads J having oil-absorbing wipers suitably fixed around them, and entered by bending the tubes 1 between the parallel side guide-bars, a a, and the stem H is weighted adjustably at H, sufficiently to 'overbalance the oil-cup K to either side as the strokes of the crosshead are reversed. In the drawings the cross-head is moving to the left hand on the outward stroke, for example, and the left-hand head J rests upon the lower bar a to wipe and oil it, and the opposite or right-hand head J j rises against the upper bar a to wipe and oil it, and on the reverse or rearward stroke the right-hand head J 2 j will oil the lower bar a in advance of the crosshead,while the left-hand head will oil the upper bar, as will readily be understood.

The oil-cups shown may be substituted by recesses in the oiler-heads, forming'reservoirs for the oil, and connecting by suitable passages with thc wipers or pads of the heads.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. An oiler for the guides of engine crossheads and other reciprocating parts of machinery, constructed with apair of opposite pivoted oiling-heads carrying or connected with an oil cup or cups, and having a weighted stem adapted to be thrown to either side of a vertical line for bringing the oiling-heads in con tact with the guide bar or bars by the inertia and momentum of the parts on reversal of the motion at the limits of the stroke of the crosshead in either direction,substantially as shownand described.

2. In an oiler, the combination, with a weighted stem pivoted to-the reciprocating cross-head, of an oiling-head actuated by the swing of the stem to either side, so as to bear the oiling-head on the cross-head guide in advance of the moving cross-head, substantially as shown and described.

3. The combination, in an oiler, and with the reciprocating cross-head A. and guide B, of the pivoted head H, carrying a weighted stem, H, and pivoted arms I, swung by the stem and provided with oil cups or reservoirs and absorbent wipers J j,receiving the oil and distributing iton the guide, substantially as shown and described.

4. The combination, with the cross-head A and its side guides, a a, of the pivoted heads G, carrying oil cups or reservoirs and weighted stem H the hollow arms P, and the oilerheads J 2 j, working between the guides a a, substantially as shown and described.
