and rotating flat slide control.

Addition to patent no. 43296 of December 19, 1886.

Patented in the German Empire on March 22, 1887. Longest duration: December 18, 1901.

The modification of the subject matter of the main patent consists in the fact that instead of a single piston, two pistons are used, each of which fits into a bore S ^{1 of} the cylinder S , FIG. 1. The pistons are connected to one another by a rod e connected, that when one piston is pressed into the cylinder, the other goes back.

The spiral ring g attached outside the cylinder is only effective on the half designated g ¹ , the other half is ineffective and attached only with regard to strength and appearance.

As the cylinder rotates, the piston resting on the part g ^{l of} the ring is pressed into the cylinder, whereby the lubricant is pressed to the point where it is to be used. At the same time, the other piston sucks lubricant from the container c. After half a revolution the pistons change their activity.

Since the pistons alternately suck ie during half a revolution of the cylinder and pressing, so that jr in the face ^'2 are correspondingly x of the frame against which the cylinder S with its surface y ^l present, arranged attached channels as follows. The channel V ₄ forms a semicircle which, through a bore V _{5, is} connected to a lateral pipe socket d, FIG. 3, from which a pipe leads to the machine parts to be lubricated. The channel V ₂ , which is connected to the lubricant reservoir c through the channel v _% , also opens into a semicircular channel V ₆ . The bores S ^{1 of} the cylinder S alternately connect with the channels V ₄ and v _e through channels v ^1. This ensures that each of the pistons is in connection with the container c _{during the suction through the channels v e} V ₂ V ₃ , whereas the same comes into connection with the nozzle d during its pressure action through V ₄ V _5.

Claims (1)

Patent claim: The following modification of the patent no. 43296 protected arrangement Lubricating pumps, which form of modification results when the rotating body of the main patent instead of a single-acting piston pump, it has two pistons whose pistons rotate without the aid of springs are moved alternately outwards and inwards by one after half a spiral turn shaped half-ring or by one after two half spiral turns, of which only the one active, formed ring, instead of the one formed after a whole spiral turn, formed ring of the main patent, while the rest of the arrangement of the main patent is followed.
