Title: Variable transmission level luffing device for derricks and jib cranes
IPC: B66C23/10
Filed: 1947-02-19
Abstract: 626,381. Cranes. GOODMAN, R., and JACOBY, H. J. Feb. 19, 1947, No. 4768. [Class 78 (iv)] In a level luffing jib crane of the kind having a hoisting drum with a hoist cable whereby to raise or lower the load, and a luffing drum with a luffing cable whereby to raise or lower the jib, the two drums are interconnected by a variable-speed gear continuously influenced by means controlled by the jib to alter the ratios of rotation between the two drums to desired amounts, whereby upon an upward luffing operation said hoisting drum will pay out sufficient hoisting cable to prevent any raising of the load, and, vice versa, upon a downward luffing, said hoisting drum will take up sufficient cable to prevent any lowering of the load. The hoist drum 15, Fig. 2, is driven through reduction gearing and a flexible coupling 36 by motor 19 which also drives, through a magnetic clutch 22, the input shaft 23 of an infinitely variable gear 24 of the double cone and chain type the output shaft 25 of which drives the luffing drum 33 through a flexible coupling 32 and suitable reduction gearing. Movement between the cones is controlled by links 29, 30 operated by a spring 55 and cable 47 which cable allows the spring 55 to expand-or contract according to the position of a grooved cam 41, Figs. 2 and 4, fast with the jib 13, to which cam the cable 47 is attached. The arrangement being such that upward motion of the jib reduces the effective diameter of pulley 26 and increases that of pulley 27 so effecting an increase in the relative speed of the hoisting drum with respect to the luffing drum. Movement of the gearing may be controlled by the application of magnetic brakes 56, 57 and an emergency hydraulic brake 35. In a modification the cam 41 may be so shaped that the load is raised slightly at the end of each luffing operation. In a further modification (not shown) a second motor of lower power is coupled to shaft 25 which motor operates the mechanism during luffing operations only, the motor 19 being then temporarily disconnected from the electric power supply.

Abstract: 639,296. Air line oilers. NORGREN CO., C. A. Feb. 23, 1948, No. 5320. Convention date, Oct. 10, 1938. [Class 12 (iii)] In a lubricator for a pneumatically-operated device, comprising a valve body 5 having a passageway 7 for a flow of compressed air and a restriction 8, and an oil bowl 6, an air port 17 containing a ball check valve 15 connects the passageway 7 with the interior of the bowl 6 ahead of the restricted portion 8. A plug 14 screwed into the underside of the body 5 houses the ball valve 15 which is held in its normal open position by a spring 16. A syphon 20 has its lower end 20a immersed in the oil, and extends upwardly into a part 5a of the lubricator body 5 to connect with a chamber 21 in the head 5b of the body. An adjustable needle valve 27 is disposed in the chamber 21, and a passage 22 in a threaded plug 23 communicates with the interior of a sight-feed glass 24 which in turn communicates with a port 25 in the restriction 8. The syphon 20 has a ballcheck valve 31 disposed in a plug 29 which is permanently attached to the body 5. The oil bowl 6, which is preferably of transparent material, has an annular flange 9 engaged by a ring 10 which is secured to the body 5 by means of screws. A filler plug 33 is provided. In operation, the Venturi effect causes oil to flow through the passage 20 to the chamber 23 from which it is metered through passages 22, 25, to the passage 7 where it will be atomized by the flow of air or gas and carried to the pneumatic device to be lubricated. When the plug 33 is removed to replenish the oil in the bowl 6, the ball valve 15 closes preventing a rush of air through the lubricator and out through the filler opening. The ball valve 31 also closes preventing the return of lubricant from the upper part of tube 20. A slight leakage of air past ball valve 15 enables the pressure to build up in the bowl 6 after the filler plug 33 has been replaced.
