Title: Improvements relating to impact presses
IPC: G05D16/10
Filed: 1963-03-25
Abstract: 957,282. Power hammers. TRANS ENERGY CORPORATION. March 25, 1963 [April 26, 1962], No. 11731/63. Heading B3H. An impact press has a ram recocking device supported on the frame of the press in such a way that, at the moment of impact, the device is substantially disengaged from the frame so that no impact forces are transmitted to the device. The ram 16, carrying die 22, is driven downwards by compressed air in the sealed chamber 12 on to a die 46, carried by a base 24, which is suitably supported on a table 26. The chamber 12 and the base are connected by four columns 28, 30, 32, 34 which act as external guides for the ram and internal guides for the yoke 60 of the recocking device 58, which is vertically reciprocated along the outside of the columns by piston and cylinder devices 162, 166, and 164, 168, which are constructed and function the same as devices 162, 166. The upper end of cylinder 170 is slidable within piston 162 and its lower end is welded to the upper end of a second cylinder 172 which is slidable through sleeve 176 of the base 24. The yoke is supported relative to the frame prior to a working stroke partly by hydraulic fluid under pressure, admitted to the cylinder 172 through port 190 of fixed sleeve 184, and partly by the abutment of the base of cylinder 172 with the shoulder 174 of the base 24. The ram is restrained prior to a working stroke by star wheels 86, 88 carried by members pivotally mounted upon shafts 74, 78 which are carried by the yoke. To initiate the working stroke the star wheels are withdrawn, by piston and cylinder mechanisms 102, 104, which may only be operated subsequent to the withdrawal of safety blocks 134, 144, by suitable means (see Fig. 4). The ram thus moves downward at high speed causing the frame and the yoke supported thereon to move upwards. At the same time the pressure within the piston and cylinder mechanisms 162, 166 and 164, 168, is released at such a rate that at the moment of impact the yoke is not supported hydraulically or mechanically upon the frame and is thus substantially disengaged therefrom. After the working stroke the yoke is lowered, the star wheel re-engaged, and the ram retracted to its initial position, against the pressure in the chamber 14, in readiness for the next working stroke.

Abstract: 1,183,474. Clutch combination and control. BORG-WARNER CORP. 15 March, 1967 [24 March, 1966], No. 12179/67. Headings F2C and F2L. A separating friction clutch C in series with an hydrokinetic torque converter B is arranged between the converter impeller B-1 and the usual rotatable, engine (e.g. diesel)-connected, housing 20 surrounding the converter so that upon clutch disengagement the comparatively large inertia of the housing is eliminated from the converter. A common hydraulic operating system (Figs. 2, 3, not shown) is provided for the converter and the clutch, the latter being completely disengaged, e.g. during shift in a series-connected change speed gear, or partly disengaged for split power train applications. The converter B comprises the impeller B-1 rotatably supported by bearings 32 on a fixed sleeve 30, a turbine 23 splined to a central output shaft 26 driving, e.g., tractor driving wheels, and a stator 24 located between the impeller and turbine by thrust bearings 35, 36. The clutch comprises interleaved discs 48, 49 keyed or splined to driven and driving members 46, 41 fast with the impeller B-1 and the housing 20 respectively. The housing and the driving member 41 together form an annular servo-cylinder 43 accommodating a piston/ presser plate 44. Clutch engagement and disengagement are respectively by direction of fluid pressure to the cylinder 43 to act leftwardly on the piston/presser plate 44 and by release of pressure from the cylinder 43, the piston/presser plate being then acted on rightwardly by converter pressure within the housing 20. The converter fluid within the housing also cools the discs 48, 49. The housing 20 may also drive, through gears 55, 56, a gear reduction unit 57. The unit 57 may be replaced by an hydraulic pump for operation of an earth moving bucket, the available power for which being adjustable by variable engagement of the clutch C to adjust the torque absorbed by converter. The control (Figs. 2, 3, not shown) comprises a multi-stage regulator valve (90) by which pressure from a pump (60) is supplied at higher and lower predetermined pressures respectively to the clutch C and the converter B. The higher pressure is directed through a manual valve (61) providing both on and off and intermittently variable application of the clutch, and a spring- loaded valve (63) which provides a timed clutch apply pressure build-up and is so responsive to the static charging pressure of the converter that it determines the differential between the ultimate clutch and the converter charging pressures thereby improving seal life. The valve (63) relieves excess clutch apply pressure.

Title: Improvements in moulding apparatus for glass or other plastic material
IPC: C03B11/00
Filed: 1919-05-16
Abstract: 149,757. Mount, L. Le B. May 16,1919. Pressing.- Relates to apparatus for pressing glass or other plastic material into open-ended articles of cylindrical or other form, e.g. miners' lamp glasses. The apparatus consists of a plunger b, reciprocated by a cam 1 on an overhead shaft 2, and a mould a which is bored with a recess c, of the outer dimensions of the tube z to be formed, and has a lower recess i n t o which the plunger justs fits. This lower recess receives the charge of molten glass, and when the plunger descends, the metal is forced up into the recess c to form the tube z, the excess metal being cut off by the descent of the plunger into the lower recess which has a movable bottom to permit this movement. The principal feature of the present invention consists in the provision of a ring p, free to slide on the plunger against the action of a spring q, which closes the top of the mould before the plunger has entirely forced the material therein. The mould and the plunger are also adapted to be rapidly rotated relatively to one another in order to produce highly-finished articles. In this construction, a bevel friction wheel k, yieldingly mounted on a driving-shaft l, is adapted to engage a bevel friction wheel j formed in one with the mould a, and also with.a similar wheel m formed on the sleeve n in which the plunger b slides. A number of moulds may be mounted in a rotating table adapted to bring them successively beneath the plunger and in engagement with the bevel-wheel k. The mould may be slightly tapered internally to facilitate removal of the finished article.
