Title: Improvements in or relating to control apparatus for hydraulic broaching machines
IPC: B23Q5/06
Filed: 1938-02-17
Abstract: 509,271. Hydraulic broaching - machines LAPOINTE MACHINE TOOL CO., Ltd. (Lapointe Machine Tool Co.). Feb. 17, 1938, No. 5025. [Class 69 (ii)] [Also in Group XXII] In a hydraulic broaching-machine a manual or automatic ram controlling device actuates a pilot valve which controls a hydraulic relay mechanically connected to the main control valve. The ram cylinder 10 which moves the piston rod 12 downwards on the working stroke is connected by lines 30, 32 to the main valve M. The line 32 has an adjustable back pressure valve 33 which may be by-passed by a check valve 35 opening towards the cylinder 10. A pump P preferably of variable delivery type delivers fluid to a longitudinal channel in the main valve through a line 20 and in the neutral position shown in Fig. 1 this fluid passes to the exhaust line 28. The machine is controlled from a lever 15 which may be actuated either manually from a handle 17 or automatically. The lever operates the spindle of a pilot valve V which is supplied from an auxiliary pump P' through a line 65. The pilot valve is connected through lines 80, 81 provided with adjustable needle valves 82, 83 respectively to the relay R the piston 51 of which is connected to a lever 53 on a spindle 54 which is also connected by an arm 55 to the main valve so that the. relay and main valve pistons move in unison. The needle valves may be by-passed by check valves 86, 87 to permit free flow from the relay to the pilot valve. Surplus oil from the pump P' passes through a relief valve 66 and line 67 and circulates round the casing of pump P for lubricating and cooling. In operation, in the neutral position shown in Fig. 1, delivery from the pump P<1> passes through lines 80, 81 maintains a balanced pressure on the relay valve to keep the valve in its neutral position while the main pump delivery passes through line 28 to exhaust. When the valve V is moved to the left the relay valve is moved to the left at a controlled speed by flow through the needle valve 82 carrying with it the main valve so that the main pump delivery passes through line 30 to move the ram downwards on its working stroke. Fluid beneath the ram piston passes through the back pressure valve 33 and line 28 to exhaust. Similarly when the pilot valve V is moved to the right, flow from the auxiliary pump passes to line 81 and moves the relay valve and thus also the main valve to the right. In this position the main pump flow passes to the bottom of the main cylinder through the valve 35 and returns the ram to its upper position. The pistons of the main valve are notched at their ends so as to avoid too sudden opening or closing of the valve ports.

Title: Improvements relating to textile ring doubling or twisting machines
Inventor: RIDGWAY FRANK
IPC: D01H7/62
Filed: 1954-02-22
Abstract: 761,155. Doubling rings-lubrication. ARUNDEL COULTHARD & CO., Ltd. Jan. 31, 1955 [Feb. 22, 1954], No. 5100/54. Class 120 (2). A textile ring doubling or twisting machine in which each ring is lubricated by a wick extending from an oil trough in the ring rail to a groove in the ring face is characterised in that a tube is secured to the ring rail and extends at its upper end into the trough and at its lower end constitutes a pump piston in a cylinder held against movement in a fixed part of the machine, the cylinder receiving surplus oil from the ring or rings which are supplied with oil from the trough, such that in one direction of movement of the ring rail the pump delivers oil into the trough to give the wicks a copious supply of oil for the ring or rings, and in the other direction of movement surplus oil is returned to the cylinder for re-pumping. In the arrangement shown each ring b has an oil groove e around its internal face with a wick f therein, the two ends of which extend back to a trough g in the ring rail a. A tube h which is secured in the ring rail (Fig. 4) forms at its lower end a piston i moving in a cylinder j secured at its upper end in a cap k of a cylinder m connected integrally. with a lower cylinder n which is secured by a clamp o to a fixed sleeve p on girder q. There are holes s in the tube j and oil fills the cylinders m and n to a level above these holes s. A drain tube u is secured at its top to an annular oil reservoir v having a filter w and moves in an outer tube u<SP>1</SP> fixed in the cap k. As the ring rail is lowered the holes s are first covered by the piston, and oil in the cylinder j is forced up the tube h to the trough g and hence fed via the wick f to the ring b. Surplus oil drips from the ring b into the ring rail a shaped as at 23 to form a receptacle and flows by tubes 24 to the reservoir v. A supplementary receptacle y is provided having a plunger z which may be depressed to flood the wicks at starting up.
