336,352. Chalmers, R. A., and Tecalemit, Ltd. Aug. 15, 1929. Force-feed lubricating; controlling flow of lubricant.-In a lubricating system for motorvehicles or other machines, all the lubricators, mounted on or connected to the parts to be lubricated, are arranged in one or more groups, the lubricators in each group receiving their supply of lubricant under pressure from and being connected in series with a master lubricator arranged in a readily-accessible position and adapted to be supplied by a grease gun or pump, and a valve 26 is adjustably threaded in the interior of each lubricator so as to increase or decrease the quantity of lubricant permitted to pass through the outlet 31 to the part to be lubricated. A master lubricator may be adapted to supply more than one group of lubricators, or a pipe supplying a group can be branched from the pipes of another group. In the case of a master lubricator 24, Fig. 6, part of the lubricant supplied thereto through a nipple 32 passes to the outlet 31 through passages 27, 28 in the valve 26 while the remainder passes through a port 37 into an annular recess 36 encircled by a ring 34 secured to one end of a pipe 3. The other end of the pipe 3 is secured to a similar ring 34 encircling an annular recess 45 on the next lubricator 38, Fig. 2, of the group, and the recess 45 communicates through a flat 60 with another recess 46 encircled by a ring 44 secured to the end of a pipe 8 leading to the next lubricator. The recess 46 communicates with the interior of the lubricator through a port 47, so that a part of the lubricant flowing along the pipe 3 passes to the outlet under the control of the valve 26, while the remainder passes through the pipe S to the succeeding lubricator. The lubricant reaching a recess on the terminal lubricator 57, Fig. 8, of a group passes directly into the interior through a port 59.
