Abstract: 860,799. Copy - milling. GAUTHIER G.m.b.H., A. Aug. 18, 1958 [Sept. 7, 1957], No. 26541/58. Class 83 (3). A template - controlled copy-milling or engraving- machine comprises controltemplates 14 with straight bases, each template being movable in a direction at right-angles to its base through contact with an abutment 17 slidable along the template on a guide 16 parallel to the base, and electrical, hydraulic or (as shown) mechanical means 28 for transmitting movements of the templates to the tool and/or work. A slide 5, supporting one or more milling-cutters 9 and their electric driving-motor 10, is mounted for template - controlled lateral movement on needle-bearings 44 on a platform 4 moved vertically under the control of another template. The template 14 controls movement of the work-table 3 on needle bearings 44 in a direction perpendicular to the lateral direction of movement of slide 5. For adjustment, movement of table 3 in the same direction as slide 5 is effected by a handle 46, and in the vertical direction by handle 45. A number of workpieces may be machined simultaneously. Each template is carried by a holder 11 fixed to a pivot 13, which is oscillated upon movement of the template by abutment 17. The templates may be curved about the axes of pivots 13. Arms 28 fixed to the pivots convert the oscillations into translations of the tool-slide 5 and work-table 3. Arm 28 for the table engages this through a roller 31 adjustable along the arm by a screw 33 to adjust the extent of movement, a spring (not shown) maintaining engagement between the arm and table. The arm 28 effecting vertical movements of the tool-platform 4, engages an abutment 35, Fig. 9, on a slide 34 in a guide 1a on the machine-bed 1. A track 36, fixed on a pivot 39 in slide 34 and engaged by a follower-roller 37 on the platform, is adjustable as to inclination by a hand-turned worm 41 engaging a worm-wheel 40 on the pivot. A handle 38 locks the track, which is set horizontallywhen it is desired not to move platform 4. This mechanism may also be used if it is desired to move a work-table in a direction parallel with the pivotal axis of its templateholder 11. The template &c. for moving slide 5 horizontally is not shown. The abutments 17 are traversed by rack-and-pinion gearing. In a modification, Fig. 3, all three abutments 171- 173 are mounted on a carriage 18 for movement along a single guide 16, each abutment engaging its respective pivoted template 141-143. The carriage is traversed by a rotating shaft 20 driving a pinion engaging a rack 19 on guide 16. Traverse and rotation of the milling cutter are stopped by switches operated by the carriage.

Abstract: 837,040. Fluid delivery installations. MULLER, J. Aug. 26, 1957 [Nov. 9, 1956], No. 26845/57. Class 99(2). A delivery installation for fluids or granular particles comprising a remote control device combined with a flexible pipe 1 has one or more pipes or electrical conductors 19 arranged freely and in a fluid-tight manner in the pipe 1. The pipe 1 is provided at its free end with a connector 2 to which is fitted a delivery nozzle 3 with a cutoff valve 4, the other end being fixed at 5 to the hub 6 of a horizontal winding reel 7 mounted on a vertical spindle 8. A central aperture 9 in the spindle communicates at one end with the pipe 1 and at the other end to a feed pipe 10. The remote control device is of the hydraulic type and is formed by a lever 11 rigid with a pinion 12 engaging a rack 13 on a piston 14 which moves in a cylinder 15 in the connector 2. A spring 16 urges the piston 14 and lever 11 to the rest position as shown where a port 17 interconnects the pipes 1, 19. The cylinder 15 is connected to the flexible pipe 19 and leads at 20 into the hub 6 of the drum 7 for connection to a hydraulic ram 21 wherein a piston 23 connects to a collar 25 of a sliding member 26 which is limited in movement by a pin 28. A valve 29 is opened when the sliding member is in its lower position and permits the operation of a motor 33 by fluid pressure, a pinion 34 of the motor engaging a toothed ring 35 rigid on the reel 7. When the lever 11 is at rest the flexible pipe may be unwound from the reel so as to bring the nozzle 3 to the site of delivery. When the lever is turned in the direction of the arrow F the fluid contained in the cylinder 15 is compressed and delivered towards the ram 21 causing the member 26 to fall and thus operate motor 33 which rotates the reel 7 and winds in the pipe 1. Return of lever 11 to the rest position immediately stops rotation of the drum and permits complete or partial reeling of the hose. In Fig. 2 (not shown), the remote control device is a plug or vane type valve which places the inner tube in communication with the atmosphere. At its other end the inner tube connects with a cylinder, the piston of which operates a rack engaging a pinion connected to a multiple electric switch. The cylinder is fed with compressed air so that operation of the remote control valve can obtain required displacement of the piston with consequent regulation of both fluid flow and reel rotation. In Fig. 3, (not shown), the remote control device has a pinion and lever engaging a Bowden cable which connects to a switching assembly and allows selective operation of fluid flow and reel rewinding.
