LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 595,826, dated December 21, 1897.

l Application filed May 3,1897. Serial No. 634,939. (No model.)

bya handle when required for filling or otherwise.

In the annexed drawings, Figure l is a side view of the apparatus with the casing in section. Figs. 2 and 3 show in dierent positions /the arrangement for disengaging the screw from the clockwork, so that the piston may be moved by hand. Fig. 4 is a plan of the crank-handle by which the apparatus is moved by hand. The head by which the handle engages is shown in section. Fig. 5 illustrates the arrangement of the clockworktrain. Fig. 6 shows in plan a device for stopping and releasing the clockwork. Fig. 7

shows, on an enlarged scale,the balance-wheel and the pivots by which it is carried.

a is a cylindrical barrel for containing the lubricant. It is lled by removing it from the cover b at its lower end. This cover is adapted by a screw-thread to the machine which requires lubrication, and it has a duct h through it, through which when the apparatus is at work the lubricant, such as vaseline, is gradually expelled.

c is a piston workin g in the cylinder a, which is driven downward by the rotation of the screw d, and is so made as to expel the lubricant. On the head of the screw d a toothed wheel e is fixed, and this is engaged by a pinion f' on the axis f. On the same axis is another pinion f 2, which can be brought into engagement with the toothed wheel g or drawn up out of engagement when required. It is shown in the first-mentioned position in Fig. 2 and in the latter position in Fig. 3. For this purpose the axis f is so arranged that it can slide in its bearings in the casing. It is pressed downward by al spring f8, which is compressed when the axis is drawn upward.

h is a head which is received by the axis f and is secured to it by a small screw h'. To the head h a crank-handle t' is readily applied, a fork on the handle embracing the neck of the head, as is seen in Fig. 4..

t" is a latch by which the handle can be locked fast tothe head.

The toothed wheel gis upon a spring-barrel, such as is common in clockwork. The spring is wound up from time to time, as required, by a key applied to the square g'.

In Fig. 5 the clock-train can be traced. The wheel g drives the pinion 1, and the wheel 2 on the same axis with the pinion 1 drives the pinion 3, which is fast with the wheel 4, which drives the pinion 5, which is fast with the wheel 6, which drives the pinion 7, on the y axis of which is the escapement-wheel.

la is the'balance-wheel, which controls the escapement in the ordinary manner. The axis of the balance-wheel is coned at the ends, asis seen in Fig. 7, and these cones enter small holes drilled into the studs lo k. The arrangement is such that the points at the ends of the spindle are not exposed to wear, and the holes in the plugs also serve to retain the oil with which the pivots are lubricated.

Z is a light spring-finger which can be brought against the periphery of the balancewheel k to retain it at rest, as is shown in Fig. 6. The nger is carried by an arm Z', which can turn about a center Z2. The handle Z3 is upon it, and by turning it a short distance in the direction of the arrow shown in Fig. 6 the clockwork is liberated. lm, is a glazed window in the casing, through which the clockwork can be inspected, or the cylindrical casing containing the clockwork may be wholly of glass.

When the apparatus requires illing, the part a is detached from the part b, the clockwork is stopped, and the handle i is applied. The handle is drawn upward, thereby causing the pinion f2 to be disengaged from the wheel g, while nevertheless the pinion f' remains engaged with the wheel c. Then by turning the handle the piston 'c is run up to the top of the barrel a. The barrel is then lled with the semifluid lubricant and is re- IOC) placed upon the lower part I). Then by again turning the handle 1I in the opposite dii-eetion the lubricant is fed downward through the duet b. As soon as it commences to issue the handle is removed, the clockwork is started, and the clockwork will then slowly continue, the downward movement of the piston feeding the lubricant downward at the slow rate to which the instrument is adjusted.

The combination of a grease-container, a piston by which the grease is expelled therefrom, a screw which propels the piston, a toothed Wheel e operatively connected with the screw, a clockwork that :normally drives the screw, an endwise-movable axis and two y GUSTAV WALCH.
