Title: Improvements in or relating to mechanism for attaching implements to a tractor
IPC: A01B59/042
Filed: 1954-02-12
Abstract: 752,807. Tractor - mounted implements. INTERNATIONAL HARVESTER CO. Feb. 12, 1954 [Feb. 25, 1953], No. 4204/54. Class 6 (1). Mechanism for attaching implements to a tractor comprises a U-shaped drawbar 15 pivoted to the tractor 11 and having laterallyspaced rear-end sockets 19, 20 for the reception of spaced spigots 21 on the implement 22, the rear end portions of the drawbar being connected by links 40, 41, to the rearwardlydirected arms 28, 29 of a U-shaped rock-shaft journalled in transversely-spaced bearings 33, 35, the rock-shaft being raisable by a hydraulic ram 50, and the arrangement is characterized in that one of the bearings 35 is capable of vertical floating movement so that the implement can rock about a longitudinal axis, a lost-motion connection being provided between the rock-shaft and power-lift to permit such rocking. The front part of the drawbar 15 is pivoted to a swinging stirrup 26 on the tractor chassis and can be raised or lowered, independently of the power-lift 50, by a link 73 connected to a lateral power-lift arm 72 operable by the tractor motor. The bearing 35 is carried by a pivoted plate 36 to which is welded an arm 37 having a pin-and-slot connection 66, 67 with a link 68 pivoted to the tractor chassis. If desired, the pin 66 may be inserted in a fixed lug 67a to eliminate floating of the bearing 35. Lateral swinging of the drawbar 15 is permitted by the links 40, 41 which are ball-jointed to the rock-shaft arms and freely pivoted to upright members 43, 45 on the drawbar. This swinging may also be eliminated by locking the links to the uprights with pins 47. The double-acting ram 50 is pivoted between the tractor chassis and a pivoted arm 57 through the free end 60 of which passes a rod 61 pivoted to an arm 64 integral with the rockshaft. The end 60 is constituted by a swivel collar which slides on the rod 61 unless prevented by contact with a cap 62. This constitutes the lost-motion connection permitting floating of the bearing 35. The latter can be positively adjusted by a power-lift arm 71 operating a push-rod 70 which can be pinned to the arm 37. Specification 741,976 is referred to.

Title: Improvements in or relating to oxyacetylene or like burners
IPC: F23D14/82
Filed: 1929-02-08
Abstract: 325,380. Wade, H., (Soc. L'Air Liquide, Soc. Anon. pour l'Etude et l'Exploitation des ProcÚdÚs G. Claude). Feb. 8, 1929. Blowpipe. burners.-In order that an oxyacetylene or like burner may be used with a choked flame without bachfiring the oxygen is supplied under pressure through a reserve chamber D to a nozzle I thereby inducing a flow of acetylene to the mixing chamber M through a ball-valve S and a bye-pass controlled by a cock V, and compressed air is supplied to the mixing chamber through a cock C which is adjusted until the discharge pressure is equal to or above that in the mixing chamber. The acetylene supply is regulable by a valve B. When the flame is to be choked the oxygen cock X is closed. As the pressure in the chamber D falls the amount of acetylene fed through the valve S falls and the flow of air to the mixing chamber rises until when the oxygen flow from the nozzle I ceases the burner operates only on the acetylene fed through the bye-pass V and the air passing through the cock C.
