T 0 all whom it may concern:

lie it known that l, ALBERT SzANTo, mechanical engineer, a citizen of France, residing at Paris, 31 Avenue Tru'daine, France, have invented new and useful Improvements in Lubricating Apparatus, of which the following is a specification.

This invention relates to a lubricator adapted to supply a number of lubricated places through an equal number of lubricator pumps.

The pistons of all the lubricator um s fed by separate conduits that can be c ose( individually are driven by one single eccentric, through the medium of a ring located on the eccentric, which ring does not rotate with said eccentric, but describes only an oscillatory motion. The pistons are placed directly against this ring so that the piston pressure is uniformly transmitted through the ring upon the eccentric. contact between ring and pump piston an exchangeable bar .is arranged. so that the wear and tear is reduced to a minimum. This construction permits the individual pumps to become independent of each other during their operation and as there is wanting any connection by means of rods, levers or the like between the driving element and the ump piston, it is possible to form each sing e ump so that it constitutes one whole by itse f, w iich whole can be easily inserted in the apparatus and can as easily be removed therefrom, after the feed conduit belonging to the individual ump is closed.

In the drawing which i ustrates a form of execution of this invention: Figure 1 shows a vertical section with partial side view Fig. 2'

shows a horizontal section with partial top view. Fig. 3 is a front viewon a smaller scale. Fig. 4 shows a single pump in section on a larger scale and of a sight y different form.

ring. At the contact point of the pump pistons with the ring, a steel bar 8 is exchangeably provided on the latter in order to ren- At the point of- -duit.

der harmless any wear and tear that may occur in this place.

Each pump piston 5 moves in a tube like pump body 9 which receives all the component parts belonging to the individual pump. The'pump piston opens in its backward position the suction holes 11 which run fi'om the cut-in collecting groove 10 into the interior of the pump cylinder. The oil flows from the oil vessel 12 through the distributing element 13 with its regulating cocks 14, further through the sight glasses 15 and the pump conduits 16 toward the individual pump pistons. The pum piston presses the oil into the; channel 18 (Fi 4) by displacing the body of the return va ve 17 contrary to the pressure of spring 19 provided in this valve body. The oil flows from channel 18 into valve body 17 through slits 23 from where it is conducted to the pressure con- The spring 19 of the return valve presses against the perforated disk 20 which serves, at the same time, as base for the lead ring 21 effecting a tight and secure closure of the connecting socket 22.

In Fig. 4 instead of forming the inlet passages 16 in the casing which surrounds the eccentrics as in Fig. 1, said inlet is formed in a projection 3 of the said casing, as shown at 16 in Fig. 4. The sight glass 15 leads directly to this inlet and is supported bythe projection 3 and is connected as before to the distributing element 13 with its regulating pock 14*. Aside from this however the construction shown in Fig. 4 is the same as shown in the other fi ures.

All parts of the in ividual pumps, that is,

piston, piston spring, valve with spring and connecting socket, are thus carried by the tube-like pum body 9, or held together by the latter. T is pump body is screwed into be exchanged withoutdifliculty. When a cock 14 is closed, the sin is lubricator pump belonging thereto can e easily removed without the necessity of stopping the remaining pumps.

The present lubricator ermits further the the casing of the lubricator and can therefore o fpiirsp removehly held in said casing at see,

transmitted to. the eccentric so that the weer endigteer to which the single parts are subjected is very slight, even ethigh speed.
