A tufting machine comprises parallel looper and knife mechanisms independently driven via variable-stroke eccentric mechanisms and timing belt transmission arranged at least at one end but generally both ends of the machine, the driven parts of said mechanisms being longitudinally spaced from a parallel-disposed vertically-adjustable jute or cloth bedplate whereby the central area of the machine between the drive parts of the mechanisms and the bedplate is substantially free from driving shafts ...

A drawing machine having a drawing zone (8) for drawing silvers (2), and a plurality of flyers (14) for winding the silvers on to bobbins (16), is made compact by arranging the flyers substantially longitudinally of the paths of the silvers through the drawing zone, e.g. in echelon formation with respect to the silver paths.

A machine for tuning a guitar comprises a pair of facing posts extending at right angles to a wall of a base to be mounted on the guitar; the posts and wall being an integral casting of silicon bronze. A worm gear assembly is mounted in bores with a common axis in the posts. The worm gear assembly includes a worm gear shaft extending between the bores and a handle carrying shaft protruding beyond one of said posts. A gear wheel assembly secured to an extending through a bore in the wall has a ge...

A machine particularly for applying labels to non-uniform items such as fruit and vegetables, the labels being provided along a carrier strip and the carrier strip having profiled edges, said machine including means for separating the labels from the carrier, a profiled means, such as a profiled roller, engageable with the edges of the carrier to advance the carrier strip from a storage means to the separating means.

A drilling machine for drilling holes in the ends of rails for a railway track to receive fishplate bolts, has a base 12 on which is provided a former 20 adapted to the profile of the rail 10. A clamping jaw 18 is connected by a clamping mechanism 16 for clamping the base 12 to the rail. An electric drill 20 is slidably supported on a column 14 on the base 12. An annular hole cutter 26 on the drill spindle 24 drills a hole through the web 40 of the rail 10. The former 30 accurately locates the d...

A bending machine comprises a plurality of bending units arranged to make bends in a common plane. The bending units are adjustably mounted to adjust the separation thereof in the common plane. Apparatus for holding and turning a workpiece about a predetermined axis is mounted between the bending units so that the predetermined axis is aligned or alignable with the common plane. The apparatus comprises a plurality of jaw members rotatable in unison about the predetermined axis. Each jaw member i...

A double-facer unit includes an applicator roller having a cylindrical outer surface with spaced depressions distributed relatively uniformly over the surface thereof, mechanisms for maintaining corrugation ridges opposite from the liner side of the single-face web against an arcuate portion of the outer surface of the applicator roller for applying adhesive thereto, and an adhesive container having adhesive therein exposed to the cylindrical surface of the applicator roller in the double-facer ...

In a shredding machine, oppositely rotating cutter shafts (11a, 11b) are driven by an electric motor (E) through an epicyclic gear mechanism (G) comprising a casing (17) with an internal gear formation (52) and a planet carrier (31) carrying planet gears (34) in mesh with the internal gear formation (52), the motor (E) driving a sun gear (35) in mesh with the planet gears (34), the drive to the cutter shafts (11a, 11b) being from the planet carrier (31). Preferably there are two planet carriers ...

A key operated manual writing machine including a writing instrument which inscribes letters on the paper, the instrument being controlled by pairs of cams, each pair coupled to one of the manual keys. The two cams control movements of the pen or instrument in two directions x and y at right-angles.
