Title: Processing plant for the blemish-free treatment of work-pieces in continuous flow
IPC: B41F17/18
Filed: 1962-09-13
Abstract: 1,017,722. Conveyers; article grippers. K. HINTERKOPF. Sept. 13, 1962 [Sept. 13, 1961], No. 34938/62. Headings B8A and B8H. Tubes 41 (Fig. 5) are fed by endless conveyers 4, 6 from a holding head 2 (at a work station 1 at which an operation such as printing or varnishing a label is effected) via a drying oven 5 to a holding head 8 for a further operation to be effected by a tool holder 9. The head 2 comprises rotating member 25 (Fig. 2) with spaced tube-holding spindles 31a, 31b . . . to which the tubes 41 are fed from a shoot 38 by a pneumatic pusher 41a via a holder 42. The head 25 carries the articles past a tool holder (Fig. la, not shown). An electric feeler (Fig. 6, not shown) senses the presence of an article at a station of the head 2. If no article is present the complete mechanism (or just the tool holder) is switched off or an alarm is given. The feeler may alternatively be operated by photo electric or pneumatic means. After the operation has been effected by the tool holder the tube is transferred by an arm 33 (Fig. 2) to a carrier of the conveyer 4 (39 in Fig. 2) the arm 33 carries a pneumatically actuated gripper (Fig. 5, not shown) having radially spaced gripper members 741 loaded by a spring 761 to a normal non- gripping position. A piston 90 actuated by pressure air from a connection 87, is adapted to urge the members 741 to gripping position. By the action of pressure air applied at a second connection 791, a piston 811 is caused to displace the whole gripper assembly (together with the gripped tube) axially. A rod 771 loaded by a spring 89 assists in ejecting the tube when the members 741 are released. In order to bring relative movement between the gripper on the arm 33 and the conveyer 39 to zero, a loop of the conveyer around a guide sprocket 45 is periodically displaceable in a vertical direction. This results from the sprocket 45 being carried at the outer end of a pivotally mounted arm 4445 which is acted on by a cam 531. The holding head 8 comprises mechanism generally similar to that of Fig. 2. The heads 2 and 8 have their individual respective driving motors from which drives are taken to the associated tool holders. The two conveyers 4, 6 however are driven from the motor of head 8. In order to synchronize the conveyer 4 (39, Fig. 2) with the movement of the head 2, a pawl 521 (Fig. 2) connected with the lever 4445 operates in association with a ratchet 50 rotating (by a chain 4445) with a sprocket 43a of the conveyer. In a modification, the drive shafts of the two heads 2, 8, are kept in synchronism by mechanical/ electric means (Fig. 7, now shown). The axis of each tube 41 is displaced through 180 degrees before the tube is mounted on the head 8 by mechanism described with reference to Fig. 4a (not shown).

Filed: 1920-12-13
Abstract: 178,882. Rogers, F. H., (Eclipse Machine Co.). Dec. 13, 1920. Turning-gear. - In an electric or other starter comprising a shaft 22 on which a driving member or pinion 26 is mounted for axial and rotary movement, the pinion is shifted axially into engagement with an engine member 28 by a member 30 acting through a resilient connection and actuated by hand or foot operated mechanism. When the engine starts, the drive transmission is disengaged automatically by means of a pinion 7 shifted axially out of engagement with a gear-wheel 25. In the form shown, the wheels 7, 25 are helically toothed, the wheel 25 being fixed on the shaft 22 and the pinion 7 sliding on keys 8 on the motordriven shaft 2. The starter pinion 26 slides on keys 29 on the shaft 22, and the pinions 7, 26 are shifted by means of sleeves 10, 30 acting through springs 15, 32 and engaged by forks 13, 33 on rock-shafts 20, 36 actuated from a plunger 38, which is pivotally connected to an arm 37 on the shaft 36 and has a pawl 44 acting upon an arm 21 on the shaft 20 on the down-stroke of the plunger. If the teeth of the pinion 7 clash with those of the wheel 25, the end of the sleeve 10 is engaged by a spring catch 16 until slight rotation of the shaft 2 brings the teeth into meshing position. The catch 16 is pivoted in a recess in the shaft 2. The starting-motor may be switched on by a contact screw carried by the plunger 38. In a modified form, the spring 15 is omitted, the fork engages a groove in the hub of the pinion 7, and a sleeve such as 30 is connected to the starter pinion 26 by a shell embracing the pinion. In another form, the shaft 22 is omitted and the pinion 7 is arranged for direct engagement with the engine member 28. In a further form, the forks 13, 33 for shifting the pinions are mounted on a single rock-shaft having an arm in the path of a pawl such as 44, Fig. 2.

Title: Improvements in and in the production of friction discs, washers, brake-linings and the like
IPC: D04H1/00
Filed: 1920-12-14
Abstract: 178,883. Scandinavia Belting, Ltd., Fenton, A. M., and Crowther, T. H. Dec. 14, 1920. Clutches, friction.- Friction discs, washers, clutch and brake facings, and steam and other joint packing are made by winding upon a bobbin, former, or clutch-cone a yarn, tape, or canvas of cotton, ramie, flax, silk, wool, asbestos, or other fibrous material or any mixture thereof, impregnating the material before or after winding with phenolic formaldehyde condensation product, and heating the wound mass to harden the binder. The mass may be subjected to pressure before heating. For producing discs or washers, the fibrous material c, Fig. 1, is wound between slidable cheek-plates b on a bobbin a, and may be subjected to axial pressure in a cylinder. The material c may be passed through a bath containing the binder, or the wound spool may be impregnated under pressure or in an open vessel, the cheek-plates and end-plates, according to the Provisional Specification, being then perforated. The cheek-plates b may be shaped to produce corrugated discs, or may be dispensed with, the material c, Fig. 7, being wound with a traverse motion between a fixed and a movable end-plate e, dried, and axially compressed in a cylinder d, preferably split longitudinally. The spool is then heated, and sawn into rings for clutches &c. According to another Provisional Specification, the end-plates and tubular bobbin may be perforated in order to facilitate impregnation. As shown in Fig. 11, V-shaped rings may be cut from the finished spool c on the lathe by an obliquely-set parting-tool. For producing segmental brake-blocks or linings, the material is wound on a drum of the desired diameter and, after treatment, cut into rings and segments. According to the last-mentioned Provisional Specification, the winding may be carried beyond the finished diameter, in order to allow for trueing- up. Coverings for cone-clutches are produced by winding the material between end-plates on a conical former or on the clutch-cone itself, temporarily provided with end-plates. Circumferential slip is prevented by holes in the conical surface, and axial slip by circumferential projections or recesses. In some cases, the working-faces of the friction-discs are constituted by the edges of the tape or the cut edges of the canvas windings.

Filed: 1973-07-26
Abstract: 1431394 Flash units PONDER & BEST Inc 26 July 1973 [27 July 1972] 35729/73 Heading G2X An electronic flash unit which includes a flash device and storage means for applying a firing voltage to the flash device has means for producing an audible alert signal when the storage means is at a voltage level sufficient to fire the flash. As shown, capacitors 24 and 26 are charged from a potential source 17, 18. A switch 25, normally open, is closed when the shutter of a camera is actuated, and this allows capacitor 24 to discharge across the primary winding 20 of transformer 19. This activates a trigger electrode 22 and causes the flash tube 12 to be fired by the voltage from the charged capacitor 26. When the voltage of capacitor 26 reaches a level capable of firing flash tube 12, a neon bulb 28 is ionized and lights up, so providing a visual indication that the flash unit is again ready for use. The neon bulb is connected via a transistor 32 to a transducer element 33 to form an audio oscillator. Thus ignition of neon bulb 28 also causes an audible alert signal to be produced by the transducer element.

Title: An automatic control system for band saw blades
IPC: B23D55/08
Filed: 1957-11-19
Abstract: 840,274. Automatic control systems for band saw blades. ARMSTRONG-BLUM MANUFACTURING CO. Nov. 19, 1957 [Nov. 21, 1956], No. 35983/57. Class 38 (4). [Also in Group XXIII] In a control system for a band saw blade, means for detecting lateral departure of the blade from a desired line of cut actuate means including a servo, for correctively twisting the blade in the workpiece to direct the blade back toward said line of cut. The blade 24 running over wheels 25, 26 is supported by the carriage 23 movable on slides along the machine bed 21. The blade is twisted through 90 degrees by guides 27, 28 to present its cutting edge to a workpiece 35 held by clamps 30 to the machine table 29. A U-shaped feeler device 37, which straddles the blade just behind the teeth, detects lateral movement and through levers actuates one or the other of two switches controlling reversible motor 120. This drives through gearing 108 a pinion 107, meshing with which are racks on the ends of levers 90, 100. The resultant small angular rotation is transmitted by levers to the blade guides to correctively twist the blade. One half revolution of pinion 107 is sufficient for an associated cam to actuate one or the other of two further switches to open-circuit the motor. The initial twist of the blade will cause it to overshoot and the motor will be energized in the reverse direction, but due to the geometry of the lever system and a mechanical follow-up link the detector-operated switch will be open-circuited before pinion 107 has moved arms 90, 100 to their opposite limits. Thus successive corrective twist angles are smaller and the blade rapidly regains its line of cut. The invention may be applied to non-continuous saw blades of the reciprocating type and is applicable to saws for cutting any material.
