Title: Improvements in power presses
IPC: B21D22/00
Filed: 1927-07-09
Abstract: 298,551. Massey, Ltd., B. &. S., and Massey, H. F. July 9, 1927. Presses, mechanical.-In a crank, eccentric, &c. operated power-driven press for trimming stampings, punching, and other purposes, hand or foot operated means are provided for barring the shaft round and bringing the ram down slowly for setting the dies &c., consisting of a ratchet wheel on the crank shaft and a driving pawl and operating lever so arranged that the pawl is out of engagement when the lever is in its normal position of rest, a device for locking the driving clutch in its inoperative position being also provided for holding the clutch out of action to allow the barring device to be used. The constantly revolving flywheel d is adapted to be clutched to the crank shaft b by a clutch i normally held out of action by the engagement of a bolt, h with the trigger j of the clutch, the bolt h being connected by a bell crank h<2> and connecting rod h<1> to a treadle g. Depression of the latter moves the bolt h out of engagement with the clutch trigger j, causing the clutch to rotate the shaft through one or more revolutions according as the treadle is allowed to rise immediately or held depressed. The shaft b is fitted with a ratchet wheel r driven by a pawl q connected to a lever p pivoted to the press frame a; the pawl is held out of engagement with the ratchet wheel by means of a pin s and projection q<1> when the lever is in its vertical position of rest but engages therewith when the lever is swung outwards. The lever is normally locked out of action by a guard lever t connected by a rod u to the treadle g. When the barring device is to be used the clutch is locked in inoperative position by means of a peg m inserted through holes in the clutch trigger and clutch casing. In the modification shown in Fig. 6 a projection v formed on or secured to the shaft b is adapted to engage the bolt h when the latter is in its normal position holding the clutch inoperative, which prevents the ratchet lever being used unless the clutch is locked.

Filed: 1933-06-30
Abstract: 420,021. Filter - presses. TEATINI, D., Hougaerde, Belgium. June 30, 1933, No. 18663. Convention date, July 12, 1932. [Class 46] A filter-press assembly comprises a pair of perforated plates a provided on their facing surfaces with corrugations in nested relationship a uniform distance apart and constituting a chamber for introduction of liquid to be filtered and a filter cloth c on each plate conforming to the corrugations. Permeable supports may be laid on the plates to form the corrugations and they may be perforated corrugated plates or sheet metal or wire supports or a wire rolled into a helix of triangular or other section. The cloth c may be gathered or puckered and sewn or woven into an edging fitting the frame, or it may be folded into pleats parallel to the axes of the corrugations and may then be formed with an edge of triple thickness. Additional loops or folds may be placed between facing edges of adjacent pleats along the edges of the cloth in order to give a uniform triple thickness and effect a fluid-tight joint. The cloth may be plane and adapted to conform to the corrugations under pressure in the press. The distance between the plates is such that for a particular liquid under a definite pressure the chamber is filled with separated solid before the rate of filtration is reduced below practical limits. The corrugations result in an increase of the filtering area for a given size of press frame.

Filed: 1973-04-18
Abstract: 1377910 Making magnetomotive devices R E PHELON CO Inc 18 April 1973 [26 Dec 1972] 18776/73 Heading B3A A magnetomotive device, e.g. a flywheel magneto, is manufactured by encapsulating a pole-shoe magnet group 8, Fig. 1, in a non- magnetic body having an axis of rotation with pole-shoe surfaces lying on an arc about the axis of rotation and serving as surfaces of flux emanation, forming the surfaces flush with the final diameter of the non-magnetic body, and removing webs 18 joining pole-shoe portions 12 of the magnet group to magnetically separate the pole-shoes. The magnet group 8 comprises a plurality of stacked ferromagnetic laminations (10), Figs. 2, 3 (not shown), fastened together by rivets 11. Leg portions 13 of the laminations define a cavity for receiving a permanent magnet 14 securely retained by tongues 15. A flywheel 32 is cast about the magnet group 8, bores 16 providing means for registration of the laminations, by die-casting. A bore (34) and keyway (36), Fig. 4 (not shown), are formed to fit an engine drive-shaft and radially extending cooling fins (38), Fig. 5 (not shown), are formed on the surface of the flywheel. Flashing is trimmed from the flywheel by stamping and the surfaces of the pole-shoes are rendered flush with the outer surfaces 29 of the casting. The web 18 is then removed by broaching, or preferably drilling out hub portion 22 to leave a bore 44. The bore may then be filled with non-magnetic material. The pole-shoes 12 are thus magnetically separated and serve as surfaces of flux emanation for magnetic linkage with a coilcore group of a stator (not shown) adjacent the rim of the flywheel.

Prior to etching in an etchant comprising 1 part of fuming nitric acid, 2 parts of distilled hydrofluoric acid and 1 part of glacial acetic acid a resist is applied to rectangular semiconductor wafers by the screen printing stencil process. The process is applied by an apparatus comprising a table 1 having a recess 3 in which each wafer is vacuum held in turn whilst printed upon through the movement of a doctor blade assembly 9 and 10 over a screen 6. Accurate location of the wafer relative to the stencil above is effected through the actuation of screws 2 by which the table 1 is moved in all directions in its horizontal plane. The screen and doctor blade assembly are pivotally mounted about an axle parallel to this plane of the table and a pipe 5 is provided by which the vacuum applied to each wafer through a pipe 4 is released. To provide the stencil on the screen a sheet of paper bearing a pigmented layer is light-sensitized in a 2% potassium dichromate solution. This paper, whilst wet, is applied to a transparent stabilizing foilpigment layer to foil-and dried. Subsequently it is placed in a copying frame so that the foil faces a lamp. A black-and-white photographic negative is laid on the foil and the lamp switched " on " so exposing the paper. After developing, the paper is stripped from the pigment layer and the unexposed pigment particles are washed out by rinsing in a water bath. The pigment side of the foil is applied to a stretched nylon cloth with the aid of a temporary glass support plate and after drying the foil is stripped off leaving the cloth with the desired stencil impressed thereon. In use those regions of the cloth outside the stencil may be covered with adhesive paper strips.

[Class 89 (iii).] A portable staping machine, particularly for operating on large fibre-board containers, comprises a frame 1 having a handle 2, a stapling head 3, a support for a wire reel 4, a clenching anvil 5 spaced from the head 3, and an electric motor 10 which drives the head 3 through gearing 11, 25 and a shaft 12. The gear-wheel 25 is adapted to be clutched to the shaft 12 through clutch members 26, 27 urged into engagement by a spring 29. A thumb-piece 15 arranged near the handle 2 and normally raised by a spring 16 is connected by a yoke 17 to a bolt 18 which is arranged to engage a part collar 31 on the clutch member 27, when the machine is idle, to hold the clutch members apart. Initial pressure on the thumb-piece 15 acts to close the motor switch 20, 21. Further pressure disengages the bolt 18 from the collar 31, allowing the clutch members to engage. The collar has a cam surface 32, which engages the bolt 18 to disengage the clutch only after release of the thumb-piece 15 has opened the motor switch.
