A self-propelled grass mower machine has a laterally projecting helically bladed cutter, a driving motor for effecting propulsion of the machine and driving of the cutter reel and transmission means for driving the cutter reel from the motor, the transmission means including a driven member, a transversely disposed driven shaft and universal couplings connecting respective opposite ends of the driven shaft to the reel and, adjacent the side of the machine remote from the reel to said driven memb...

A haymaking machine has rake heads rotatable about upwardly extending axes. Each rake head includes a central housing mounted concentric with respect to a wheeled center shaft that affords the axis of rotation of the head. A p.t.o. is connectable to driving means that rotates the housing. Each head has support arms, the inner ends of which are pivoted on horizontal axes around the lower periphery of the housing. A tine group is pivoted to the outer end of each arm and the arm as well as its corr...

A tufting machine bed having an oscillating looper assembly in which the oscillating mass is counter-balanced by mechanism including a weight which oscillates about a pivot point in the bed in a direction opposite to that of the looper assembly. The oscillatory motion of the counter-balancing assembly is derived from the same oscillating shaft that drives the looper assembly.

A step type exerciser (FIG. 3) comprises an endless loop of steps in which each step has an associated pair of pulleys, one (14) at each end, and these run on fixed "inside out" Vee belts (10). This provides a particularly inexpensive guide means which is quiet in running. Drive is transmitted by toothed pinion blocks (18, 22) carried adjacent to each roller but angularly fixed whereas the rollers are rotatable, and the blocks engage a second belt (40) which is driven by a motor (26).

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

An electric motor comprises a laminated stator core supporting windings to define similar adjacent poles. A rotor is mounted to rotate within the stator. The similar poles in a group define flux paths with adjacent pole groups. Thus the flux paths required are restricted to those between adjacent dissimilar pole groups. In this way the material of the core between the flux paths can be reduced as it is not required to carry flux itself. This redundant portion of the core can be shaped to accommo...

A reciprocatory machine having a cylinder defining with at least one piston a working chamber. Each piston is reciprocable in the cylinder by a respective crankshaft. The machine has intake and exhaust ports disposed at opposite ends of the working part of the cylinder and has respective valves additional to the pistons for opening and closing the ports. The valves are driven by the crankshaft(s) and have provision for adjusting the timing relationship between the displacement of the crankshaft(...

A wrapping machine, particularly for wrapping cigarette packets in wrapper film, includes a series of endless band conveyors (148, 152, 156, 166, 170) carrying pushers (150, 154, 158, 172) for moving successive packets (191) along a straight wrapping line. One of the pushers (158) is heated to seal a wrapper seam. Opposed heated band conveyors (166) simultaneously seal end folds of the wrapper. Packets are gripped between opposed conveyors (145, 148) immediately after intercepting a wrapper (100...

In the operative position shown in FIG. 4 a printing roller abuts the cylindrical surface of an impression roller to cause ink to be transferred from an anilox roller via the printing roller to the impression roller. The gear wheel on the impression roller meshes with a gear on the printing roller which in turn meshes with a gear on the anilox roller to cause rotation of those three rollers. The printing roller and the anilox roller can be moved to the right, when viewed in FIG. 4, to move their...

An improved drawdown machine is disclosed in which an ink bead or coloring agent is evenly distributed over a receptor surface e.g. a sheet of paper by pulling the paper through a nip formed between a bed surface and a bar.
