Title: Improvements in the lubrication of pistons
IPC: F16N7/26
Filed: 1923-03-26
Abstract: 195,626. Automatic Refrigerating Co., (Assignees of Lundgaard, 1.). March 30, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Pistons. - In order to prevent accumulation of oil on the top of a piston, a chamber is provided in which oil pushed up by the piston may accumulate, a channel being formed through which oil may pass from the chamber to some point of the circumference of the piston other than that at which oil has been pushed up and where it may pass down to beneath the piston. The action depends on the fact that there is a tendency to push oil along that side of the cylinder which is under the greatest side pressure. An annular groove 20, Fig. 2, is formed in the cylinder wall at a point slightly below the top of the piston 1 in its lowest position. If the directions of sidethrust on the cylinder wall on the up-stroke and down-stroke are in the directions shown by the arrows 22 and 23 respectively, then oil is pushed up at the left-hand side into the groove 20 and flows around the groove to 'be carried down to the crank-case on the right-hand side. Alternatively, an annular groove 20, Fig. 3, may be formed on the surface of the piston towards the upper end, the portion 25 above the groove having clearance with respect to the cylinder wall. The invention is described in connection with an air refrigerating machine, each cylinder having a compression piston 1, Fig. 1, and a shifter piston 3, independently actuated. Rods 11 driving the pistons 3 pass through bushings 12 in the pistons 1. A recess 27, Fig. 2, formed at the top of the bushing 12 acts in the same way as the groove 20 to prevent oil from being carried up to the top of the piston by the rod 11.

The punching machine 3 is driven by a connecting-rod 2 from an eccentric 1 and after the punching operation the feed band 11 is advanced by connecting-rods 4, 6, bell cranks 5, 7, pawl 9, and a ratchet wheel 10 keyed to the roller over which runs the band 11. The amount of feed is adjustable by moving the end of the connecting-rod 6 in the bell crank 7 so that either one or several rows of cakes 23 will be pushed over a discharge blade 12 on to the endless bands 18. The carriage 14 has slots 14<1>, 14<11> in which take fixed pins 15, 15<1> and is connected by rods 19, 20 to the bell crank 7 so as to be reciprocated, the forward movement coinciding with the movement of the band 11 of the punching machine. The endless band 18 of textile fabric or wire netting passes over rollers 16, 17 mounted at the ends of the carriage. A ratchet wheel 27, Fig. 5, keyed on the shaft 24 of the roller 16 engages a pawl 28 on a loose disc 26 secured to a toothed wheel 25 meshing with a fixed rack 29. The ratchet wheel 27 and roller 16 are rotated only when the toothed wheel 25 turns in a clockwise direction, i.e. only during the rearward movement of the carriage. During the forward movement of the carriage the band 18 is stationary with respect to the carriage but during the rearward movement the band is moved in the opposite direction and the cakes 23 remain in the same position in space. During this return movement the ratchet wheel 10 is not rotated so that the band 11 remains stationary and the punching out of the cakes is effected. Discharge of the cakes on to the uniformly-moving belt 30 takes place during the return movement of the carriage the cakes being pushed over the discharge roller 17. The speed of the carriage is twice that of the belt 30 so that the rows of cakes on the belt 30 are spaced the same distance as those on the band 11.
