LUBRICATO R.

SPECIFICATION forming part of Letters Patent No. 290,728, dated December 25, 1883.

Application filed June 25, less.' (Model.)

To all whom it may concern,.-

Be it known that we, DANIEL APPEL and ROBERT G. MCAULEY, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and Improved Lubricator; and we do hereby declare that the following is a full, clear, and complete description thereof.

The special purpose of the above-said lubricator is for lubricating the cylinder and valves of locomotive-engines automatically by injecting the oil to the valves by steam-pressure, substantially as hereinafter described, and illustrated by the accompanying drawings, making a part of this specification, in which- Figure l represents a side view of the lubricator, partly in section; Fig. 2 is a vertical section taken through the line x xof Fig. 3. Fig. 3 is a top view. Figs. 4, 5, 6, 7, and 8 are detached sections, to which reference will be made.

Like letters of reference refer to like parts in the several views.

As shown in the drawings, A represents an oil-vessel, which, by means of the neck B, is screwedinto the steam-boiler or any such place as may be most convenient for-the engineer to obtain access thereto.

' C indicates a portion of said boiler, and D a pipe extending from the neck down into the water and in open communication therewith. Said water-pipe is also in communication with the oil-vessel A by means of the conduit E in the neck B and the pipe F, one end of which is screwed into the conduit. The pipe extends therefrom up into the oil-vessel, near to the top, and returns down to the conduit G, and terminates a short distance above it, and in alignment therewith, as seen in Fig. 2.

In the side of the neck B, above alluded to, is inserted a screw-valve, H, of which a is the seat for opening and closing the communication between the boiler and the oil-vessel.

I is a glass tube, the lower end of which is secured in a'tubular arm, J, by a screw-cap stuffing-box joint, which is or may be like such joints in ordinary use; hence a description thereof is not essential in this place. The

upper end of the tube is, in like manner, se-

cured to a tubular arm, K, having a stop-valve at V, by which the upper end of the glass tube is put in open relation with the oil-vessel,

Awhereas the lower end of the glass tube is put in communication with the bottom of the oilvessel by the tubular arm J and conduit G, with which the bore of the tubular arm is in open communication, as shown in Fig. 2. The end of the tubular arm J terminates in an enlargement, forming a valve-chamber, L, in which is inserted a screw-valve, M, of which b is the seat. Said valve and its housings are a duplicate of the valve H, above referred to, and are for the purpose of opening and closing the communication between the oil-vessel and the glass tube, as hereinafter set forth.

The valve-chamber L, above alluded to, is provided with an outlet, N, opened and closed by a stop-cock, O, Figs. 1 and 2.

v On the upper end of the oil-vessel is screwed a cap, P, of which the tubular arm K forms a part, as seen in Fig. 2. By means of a tubular projection, Q, is secured in the cap of the oil-vessel a cylinder, E, in which is tted an elongated piston, S, provided at each end with a guide-rod, respectively, T and U, made closeitting in the heads Aand B of the cylinder by stuffing-boxes, substantially the same as the stuffing-boxes above alluded to.

In one side of the piston is a longitudinal groove, a, Fig. 2, extending from one end thereof to about three-fourths of its length. Quartering in respect to the groove a is a similar groove in the side of the piston, as indicated by the dotted lines b. Said groove b commences at the opposite end of the piston from that of the groove a, and is about the same length.

It will be observed in Fig. 2 that the groove a is in open relation with the tubular way C', and that the groove b is turned away therefrom and covered wholly by the side of the cylinder.

It will be noticed in Fig. l that in two 0pposite sides of the cylinder E there is an oileduction port or conduit, c and d. Said conduits extend to and terminate, respectively, in the tubular arms D and E'. To the ends of each of said tubular arms are connected by any suitable pipe-coupling the tubes F and G', by means of which the lubricator is put, respectively, in communication with the steamchests of the cylinders of the engine for lubricating the valves thereof.

e and f are a pair of balance-valves placed, respectively, at the j unction ofthe oil-eduction ports or conduits c and d and the tubular arms D and E. The use of said valves will presently be shown.

The piston S, above described, is given a rotative movement in the cylinder by means of the following mechanism: On the end of the piston-rod U is secured a head or block, II', Fig. 2, enlarged detached views of which are shown in Figs. 4, 5, 6, 7, and 8, representing different sides and ends of the head. On each of two opposite sides of' the said head is an inclined plane, g g, respectively extending diagonally from the corner c to the corner b.

In Figs. 2 and 4 one of the inclined planes, 0, only is seen. In Fig. 5 both are shown. Said Fig. 5 represents an end view of the head, and U the piston-rod. On the two other sides of the head is also an inclined plane, c and d', similar to the inclined planes g g', but in a reverse diagonal direction, as shown in Fig. 8, both of which are shown in Fi 7 which represents an end view of the head. The said in clined planes are also shown in Fig. 4.

It will be noticed in the drawings that the two corresponding inclined planes g and g are of equal length and terminate at the projection or lip fi, Figs. 4and .3. So also are the inclined planes d and c of equal length and terminate at the projection or lip a, Figs. 4 and 8.

To the top of the cylinder R is secured a bifurcated spring, I', Fig. 2, a section of which only is shown in Fig. 3. Each branch m and m of said spring is provided with a pin, respectively, 7L and h, which are adapted to rest upon the inclined planes, as seen in Fig. 6, in which m and m represent the two bifurcated branches of the spring, and 7L h the pins alluded to.

The use of the bifurcated spring will hereinafter be shown.

rIhe practical operation of the above-described lubricator is as follows: As aforesaid, the lubricator is screwed into the steam-boiler, so that the pipe D may extend down into the water. The pipes Fl and G are respectively connected to the steam-chests of the cylinders of the engines. (Not shown in the drawings.) The oil-vessel`is charged with oil at K, Fig. I. New, in order to force the oil from the vessel A into a steam-chest, the valve H is opened, as shown in Fig. 2, thereby allowing water from the boiler to pass upward into the conduit E to the pipe F, through which it as cends and returns through the branch F" to the bottom of the oil-vessel. The pressure of the water on the bottom of the oil forces it upward through the conduit C into the groove a of the piston and passes therefrom into the space X', between the end of the piston and head of the cylinder, which forces the piston in the direction ofthe arrow. "When the piston has arrived at the end of its stroke (which is the length of the inclined planes g and 'g'. up which the pins in the ends of the spring I slide, by virtue ofthe longitudinal movement of the piston) it receives a quarter-turn by means of the pin 7i of the branch m of the spring, having passed from off its inclined plane g, while the pin h of the branch m of the spring passes onto the projection or lip a.

The continued pressure of the spring m on the lip a (and there being no pressure of the spring m on the inclined plane g) causes a quarter-turn of the head,W or to the position shown in Fig. 8. In said position the two pins of the branches m and m of the spring will be down upon the lip a. The pressure of the two springs being now exerted equally .onboth sides of the axial line of the head prevents it from further turning. At the same time the two springs are in position to slide up the inclined planes c and d. The abovcssaid action brings the groove a of the piston to the outlet-port e. rlhis opens a free communication from the cylinder to the balance-valve c, which will be at once opened by the superior pressure of the oil on the upper end of the valve, due to the difference ofthe area of the end of the piston, as compared with that of the valve. The valve being opened, the oil is at once forced into the steam-chest of one of the cylinders, conducted thereto by the pipe F.

The rotative action of the piston, above described, in changing the groove a from the passage C to the outlet-port c, has brought the groove b to the passage G and closed it against the groove a. The oil now passes from 4C into the groove b, thence to the opposite end of the piston,which causes a reverse longitudinal movement thereof from that above described. As the piston moves back in the opposite direction of the arrow the pins of the springs ascend their respective inclined planes. On their arrival at the upper end thereof the spring m passes from off its inclined plane, while the spring m passes onto the projection or lip z', (now at the upper side of the head.) The pressure of the spring m on the one side ofthe head, and none on the other side by the spring m, rotates the head to the position shown in Fig. 4-a quarter-turn-thereby bringing the groove b in open relation to the outlet-port d, and the groove a again to the passage C, as shown in Fig. 1. This changed position of the piston opens a free communication from the cylinder to the balance-valve f, which is at once opened by the superior pressure of the oil,.-as was the valve c, above described. The valvef being opened, the oil is at once forced into the steam-chest of the second cylinder, conducted thereto by the pipe G', and cut off from passing into the iirst one above instanced by the closing of the .outlet-port c by the rotative action of the piston'.

For again -oiling the Erst-mentioned steam- IOO IIO

cylinder the operation is repeated, as in the first instance, and so on alternately each steam-cylinder is supplied with oil at each alternate reverse action of the piston, caused by the operation of the head of inclined planes and the bifurcated spring in its co-operation therewith, the two operations being substantially alike, differing only in being reversedthat is to say, the one acting to the right and the other to the left. The two operations of the inclined planes and the springs for operating the piston are substantially alike, but act reversely.

It Will be proper to remark here that the normal pressure of the water in the boiler tends to keep the balance-valves closed; hence the piston will have a certain amount of rc- `sistance to overcome at all times, so that a withdrawal ofthe pressure from the discharging-pipes F and G', in consequence of shutting oft` the steam from the engines when go-4 ing downgrade, will not interfere withvthe working of the lubricator.

When the oil is exhausted from the vessel A, which will be shown through the glass tube I, the pressure-valve H is then to be closed and the cock O and valve M opened to allorir the water in the oil-vessel to be drawn off, to be again filled with oil through the opening at IC, above alluded to.

The valve V is to prevent the oil from iowing from the vessel in the event the tube I should get broken.

What we claim as our invention, and desire to secure by Letters Patent, is-

1. In a lubricator for oiling locomotive-engines, the cylinder R and piston, provided with grooves a and b, arranged quartering in relation to each other, and alternately in open communication with the outlet-ports c and d, conduit C', and oil-vessel, substantially as herein described, and for the purpose specified.
