Title: Improvements in or relating to oil cups
IPC: F16N7/00
Filed: 1920-05-19
Abstract: 164,607. Wade, H., (Felix Manufacturing Co.). May 19, 1920. Force-feed and capillary-action lubricators.-An oil-cup having a spring-pressed piston for delivering oil to a bearing is constructed to feed oil also by gravity independently of the piston. The piston 8, Fig. 1, is drawn downwards to eject the oil below it by a spring 26 acting through a link 22 and ball 18, and oil above the piston passes continuously to the lower side through an opening 10 with wick 11 and a permeable membrane 9 attached to the piston. To fill the cup, the ball 18 is raised by lifting the cap 13, exposing an opening 19 in the piston, which is at the same time raised to a less extent by a spring 12. The piston may, if desired, be operated by pressing on the cap 13. In a modification, the pa.rts 9, 10, 11, 18 are replaced by a valve fitted with a fibrous plug in a central bore. Fig. 3 shows a modification in which the piston 78 has the form of a valve with a reduced part 79, which when raised by lifting the cap allows oil to flow into the outlet 77. After the piston has reached its lowest poisition, oil continues to be fed through a wick 82 and fibrous plug 83. In either construction, by pumping the cap up and down, oil may be forcibly expelled. To permit air to enter the cup, the link 69 is pivoted eccentrically to the cap so as to give the cap a slight tilt. A flange 65 on the cap 67 seats on a V-shaped bulge 64 on the cup, or the skirt 66 of the cap may rest on a shoulder on the cup.

Title: An Improved Apparatus for Loading Guns.
IPC: F41A9/42
Filed: 1918-08-30
Abstract: 134,259. Schneider et Cie. Aug. 7, 1917, [Convention date]. Loading-appliances.- Relates to ramming-apparatus of the kind in which a motor-actuated rammer D, Fig. 1, is moved to and fro in a fixed framework A within which is slidably-arranged a loading- carriage B having a concave upper surface to support the charge and guide the rammer. According to the invention, the movements of the rammer automatically cause the stoppage of the motor at the ends of the forward and return strokes, and also the reversal of the motor at the end of the forward stroke. In the preferred form, the motor is under the con. trol of a clutch K, J, the member J of which is mounted on a shaft i in the framing A, this shaft being connected to the controller F of the motor. The member K of the clutch is mounted on a shaft k connected to tappet gear P, Q, O, N, M, M<1> arranged on the loading-carriage B and operated by the rammer at the end of its forward and rearward strokes. The rammer is shown in the withdrawn or inoperative position in Fig. 1, the shaft i of the clutch being connected to the controller F through spur gearing I, H, G, shown in plan in Fig. 11. The clutch member J is provided with a sector-shaped recess to accommodate the other clutch member K. The central gear-wheel H is under the control of an eccentrically-acting spring T which keeps the parts in the position shown in Fig. 11. To start the motor, the handle W is turned to the left, thereby, through the gearing, moving the face j<1> of the clutch member J into contact with the member K. The rammer then moves forward to ram the projectile until its rear stop S contacts with the tappet Q, which acts to rotate the clutch member K and thereby rotate the gears I, H, G and handle W to stop the motor. Meanwhile, the spring T has passed its deadcentre position, and now acts on wheel H to rotate wheels I, G into the position shown in Fig. 14, thereby reversing the motor to cause withdrawal of the rammer. At the end of its rearward stroke, the rammer stop R contacts with a tappet P to return the clutch gear to the position shown in Fig. 11 and stop the motor. The short stroke necessary for ramming the powder charges is obtained by the contact of an auxiliary stop X with the tappet Q, this stop being connected to a spring plunger Z which is pressed inwards, when in contact with the heavy projectile, to render the stop X inoperative, the stop acting only when the light powder charges are being rammed. Fig. 18 shows a modification in which the powder charges V<1> and projectile V are rammed together into the gun, the charges being carried on a tray D<2> and resting against a plunger D<3> loosely mounted in the rammer D. The plunger D<3> engages the breech by means of a spring catch d<3>, and remains behind whilst the tray D<2> is withdrawn, until the rammer acts on a shoulder d' to withdraw the plunger from the breech.
