LUBBICATOR.

SPECIFICATION forming part of Letters Patent N0. 755,898, dated March 29, 1904.

Application filed March 24, 1903.

To all whom it may concern.-

Be it known that I, HEINRICH LUDENDORFF, a subject of the King of Prussia, German Emperor, andaresident of Berlin, in the Kingdom of Prussia, German Empire, have invented a certain new and useful Improvement in Lubricators,of which the following is a specification.

My invention relates to improvements in lubricators having a piston which is advanced by clockwork or wheel-gearing to eject the lubricant; and the objects of my improvements are to provide means for regulating the quantity of lubricant ejected in a given time and to render the piston ejecting the lubricant visible. I attain these objects by the construction illustrated in the accompanying drawings, in which Figure 1 is a plan of a portion of the mechanism of a lubricator adapted to be secured to some moving part of a machine or the like and to be actuated by the inertia of a weighted lever. Fig. 2 represents a side elevation and partial section of the same lubricator. Fig.

. 3 is a plan showing another construction of the driving part of the clockwork or other gear. Fig. 4 shows a section on the line a a of Fig. 3. Fig. 5 is a plan of a lubricator adapted to be secured to a fixed part of a machine and to be regulated by a balance-wheel or spring. Fig. 6 shows a side elevation of the lubricator illustrated in Fig. 5.

My lubricator comprises a vessel 1', on which is disposed a casing 2, which contains mechanism 4 for advancing the piston 3 in the vessel 1. In the construction shown in Figs. 1 to 4 the mechanism 4 is adapted to be driven by the inertia of a weighted part 5, While in the construction illustrated in Figs. 5 and 6 a spring and balance-wheel are provided for the purpose. The inertia of a Weighted part is utilized for actuating the type of lubricators used for lubricating the moving parts of a machine, such as the connecting-rod head of a steam-engine, while the spring and balance-wheel form the actuating or driving means of the mechanism of stationary lubricators. The weighted lever 5, Fig. 1, is turned by inertia about the spindle 7 when the part to which the lubricator is at- 5 tached is moved. On the spindle 7 is secured Serial No. 149,275. (No model.)

a ratchet-wheel 8,- which is turned by the pawl attached to the weighted part 5. In order to limit the movement of the weighted part, a pin'lO and an eccentric disk or stop 11 are provided, which latter is fixed to a spindle 12, provided with an index 13, adapted to move over a scale on the outside of said casing. The eccentric disk or stop has a number of steps 15, which on turning the disk increase or decrease the amplitude of the oscillation of the weighted part 5. In this way the movement of the ratchet-wheel 8 is regulated so that the feed of the lubricant can be adapted to requirements.

In the modified construction shown in Fig. 3 the weighted part 5 is adapted to slide in a guide 9. An arm extends from said weight through a slot in the guide 9 and carries a pawl, which is kept by a spring in engagement with the ratchet-wheel 8. The eccentric disk 11, according to its angular position, limits the stroke of the weighted part 5 more or less.

For stationary lubricators the stop 11 is adapted to limit the movement of the balance- Wheel. A pin 16 is for this purpose secured to the balance-wheel, which strikes against the inclined surface 15 of the stop, so that the speed of the escapement-wheel will be altered according to the position of the stop 11.

The position of the piston 3 in the vessel 1 can be seen through the sight-glass 17, which consists of a strip of celluloid or other transparent substance held by a frame 18 and renderedtight by suitable packing.

What I claim, and desire to secure by Letters Patent, is

1. Lubricator comprising in combination av vessel adapted to contain a lubricant and having an outlet, a casing adjacent to said vessel, a piston in said vessel, wheel-gearing in said casing adapted to advance said piston and displace the lubricant through the outlet of said vessel a movable weighted body in gear with said wheelgearing, and an adjustable stop having inclined surfaces and adapted according to its position to limit the stroke of said weighted body, substantially as set forth.

2. Lubricator comprising in combination a vessel adapted to contain a lubricant and having an outlet, a casing adjacent to said vessel, a piston in said vessel, wheel-gearing in said casing adapted to advance said piston and displace the lubricant through the outlet of said vessel a movable weighted body in gear with said wheel -gearing, and an adjustable stop having inclined surfaces and adapted according to its position to limit the stroke of said weighted body, an index connected to said stop, and a scale over which said index moves I0 substantially as set forth.

In witness whereof I have hereunto signed my name, this 12th day of March, 1903, in the presence of two subscribing witnesses.

HEINRICH LUDENDORFF.
