A rotary pump or motor has a single rotor co-operating with a stator, the peri metrical surface of one of which is cam shaped and of the other is circular to form between them a number of similar fluid spaces with at least two vanes or abutments radially slidable in the circularly profiled member to afford complementary pumping chambers which are mutually compensating to give a steady output. In Figs. 2, 3 a stator 4 is circularly profiled and contains two vanes 7 which are urged against a rotor 6 having five lobes by rings 8 contained in annular grooves in the stator 4. An inlet port 4a and an outlet port 4b are formed in either side of each vane. Passages 4c, 2c connect the inlet port 4a to an annular inlet chamber 2b closed on its inner surface by a  sleeve 9 and passages 4d, 3c connect the discharge port 4d to a discharge chamber 3b. In the surfaces of the vanes 7 at the sides adjacent the outlet ports 4b are channels 7a connecting the annular grooves to the pumping chambers. The profile of the rotor is so formed (not shown) that the vanes slide with constant or other suitable rates of radial acceleration and retardation. In another form, the rotor has an even number of lobes and the stator has two or four radial vanes being urged against the rotor by springs. The rotor may have a circular profile and contain the radially sliding vanes; while the stator has the cam-shaped profile.

Title: Improvements in or relating to single-thread lace braiding machine
IPC: D04C3/00
Filed: 1926-12-29
Abstract: 264,149. Nitz, B. Jan. 8, 1926, [Convention date]. Braiding-machines.-The bobbins of a lacemachine are traversed on a conical or cylindrical surface by means of pattern-controlled drivers 5 arranged in groups about common driving-gears D. In the base portion of each driver are housed two spring clutch pins 16 carried by a cross-head 15 mounted on a sliding rod 13. A boss 26 carrying edge cams 29 is interposed between an abutment on the standard 1 and stepped cams 14 on the end of the rod 13. When the boss is rocked under pattern control the rod 13 is moved to the left in two stages, the clutch pins 16 enter slots in the corresponding driving wheel 4 and the bobbin carriers that normally rest between adjacent drivers are locked to the selected driver by the frictional engagement of the crosshead 15 with toothed cross-bars 22 on the carrier spindles. The return action of the clutch parts uncouples the carriers from the driver after half a revolution and leaves both carriers and driver at rest. The driving wheels 4 rotate continuously and are in mesh together and are driven by gears 19, 20, D and C.

A machine tool comprises a vertically movable tool spindle, a counterbalance system for balancing the spindle and for traversing or retracting the spindle by under, or over balancing, a mechanical spindle feed drive, and a cycle control means for operating the counterbalance system to underbalance and thereby traverse the spindle until the tool engages the work, to then balance the spindle, and for selectively connecting the mechanical feed drive to the spindle responsive to such engagement so as to power feed the tool while engaged with the work. A radial-arm drilling machine spindle 14 is rotated by a motor 16 and a gear drive 17 and feeding of the spindle is provided by a pinion and rack 18, 19, which may be manually operated, or power operated from drive 17 through a shaft 22, a clutch 20, and worm and wheel 24, 25. A second clutch 26 is provided in the drive so that when the drill feed is completed, clutch 26 is disengaged, with spindle 14 rotating, and, after a short period, main clutch 20 is disengaged, thus reducing the strain on the machine due to the feed thrust. Clutch 26 may be magnetic, and may be controlled by a switch 26a, or it may be controlled by trip discs 29, which discs may also control the feed rate, feed limit, and reversals of spindle 14. The weight of spindle 14 is counterbalanced by a spring-urged hydraulic piston 35 having a rack which co-operates with a pinion 38 fixed to a sheave 39. A cable 40 is secured to spindle 14 and is tensioned by sheave 39. Dogs 46 on sheave 39 are adapted to actuate switches 48, 49, for terminating the spindle travel limits, and switch 49 may control clutch 26. Fluid is supplied to cylinder 32 by a pump 50, and valves 64, 58, 65, allow adjustment of the pressure supply to the cylinder. Valve 64 is set to produce vertical movements of the spindle, valve 58 is set to balance the spindle, and valve 65 is set to allow the spindle to move downwardly, the rate being controlled by an adjustable orifice 72. The valves are controlled by solenoids 62, 68, and a pressure switch 70 senses a difference in line pressure as the tool 15 engages the work, and closes an electrical contact 71 which actuates the power feed circuit.
