MASON'S PATENT SLUBBING AND ROVING FRAMES.
The object of these improvements is, to secure larger production, greater durability, and at less cost.
This is accomplished, first, by continuing the collar (which is firmly fixed to the lifting rail) through the pinion wheel, up the inside of the bobbin, nearly to the top, where the bearing for the spindle is formed as shown at a in figs. 1 and 2.
In order to reduce the friction, the collar is made with a recess or hollow chamber inside, so that the spindle only fits at each end. The bobbin at its upper end runs on the spindle as usual, and friction upon the outside of the collar is prevented by its being made to pass at its lower end upon a flange, which projects upon the top of the pinion wheel. The bobbin entirely covers the collar, protects the bearing from injury by dust or other matter, and thus less oil is required.
The top of the flyer is left clear for piecing-up and doffing.
These advantages are much more manifest after the machines have been some time at work, when instead of having to reduce the speed, it is generally increased a little.
Although the bobbin barrel is about 3/16 in. larger in diameter, it is not found to be a disadvantage; the frame starts better upon the empty bobbin, and a trifling addition to the diameter, when full, will hold the same length of slubbing or roving.
The difference between this mode and the best arrangements of collar previously used, is shown at figs. 2 and 3, the bearing for the spindle in the one being at a, and in the other at b, a difference equal to the length of the lift (say 10 or 12 in. slubbing and 6 or 7 in. roving frames) in favour of this patent. From the increased steadiness of the spindles, there is less wear and tear by friction.
The second improvement is in the separating plates (as shown at c in fig. 1) which prevent the ends from becoming entangled, and thus reduce the waste. They are placed between the rollers and the spindles, with convenience for removing at pleasure, to facilitate doffing and cleaning.
The third improvement is in the application of a long boss to the differential or jack motion, as shown at a a in fig. 4. The main shaft of the said motion is at b, supported by the boss a, which according to the usual arrangement terminates at the pinion c; according to this improvement, however, it is extended to the point d, and the wheels c, e, f are mounted thereon instead of upon the shaft as is usual. To reduce the friction upon the driving shaft, the long boss is recessed or chambered out, as shown at g.
The advantages of the above arrangement are, steadiness in working, reduced friction, and greater durability. This is attained by the increased length and diameter of the bearings, which are of cast-iron. The motions of the box and shaft being opposed to each other, by the introduction of the long boss, the rubbing surfaces are separated, as will be seen from the annexed sketch.
The arrangement as regards the other parts of the apparatus is that in ordinary use.
The following machines are manufactured by John Mason, at the Globe Works, Rochdale:—
Openers, scutchers, lap machines, fans, single and double carding engines, grinding machines with cement and emery cylinders and rollers, drawing frames, etc.; Mason and Co.'s patent slubbing and roving frames; throstles with band and list wharves, winding machines, reels, etc.; teazers; woollen, worsted, and silk carding engines; self- acting cotton and woollen mules and power looms; patent condensor or endless carding engine.
