IMPROVED DIFFERENTIAL MOTION.
All the gears on the Jack Shaft revolve in the same direction as the shaft itself. This reduces considerably the work the cone belt has to do, saves power, and gives more accurate winding and evener and better work.
A1 (40 teeth) drives the Spindle Shafts and S1 (50 teeth) drives the Bobbin Shafts. The gears on the Spindle and Bobbin Shafts are alike, i. e., they have the same number of teeth.
As the cut shows the number of teeth in all the gears of the Differential, it will readily be seen that if Q and Q1 are held stationary, the speed of S1 will be r.e.t.a.r.ded 1 rev. for every 5 revs.
the Jack Shaft makes, and the spindles and bobbins will be running at the same speed, no winding taking place. Winding is produced by the bobbins running faster than the spindles, therefore Q, which is driven from the bottom cone through carrier gears, must revolve. Its speed changes as the bobbins increase in diameter, being governed by the position of the cone belt, which is shifted slightly as each layer is put on the bobbins.

CASING-OFF PLATES--The Front Casing-off Plates for Bobbin and Spindle Shafts are made of polished steel and are circular in shape. They are light, strong, cannot be broken, and are easily kept clean.
IMPROVED CAP BARS--Cast-iron Cap Bars give trouble on account of the fingers being twisted, and frequent breakages. The ill.u.s.trations show the construction of our improved Cap Bar, which entirely obviates these difficulties. Figure 1 is a back view of our Cap Bar applied to a machine with four spindles in a box, and Figure 2 an end view of same. Figures 3, 4 and 5 show enlarged details.

IMPROVED CAP BARS
The Cap Bars are fastened to the Roller Stands by brackets which are independent of the slides, and consequently the rolls can be set without moving the Cap Bars. When resetting the rolls it is only necessary to adjust the nebs for the middle and back lines, as the front nebs do not have to be disturbed.

IMPROVED LAY GEARING.
[Ill.u.s.tration]
To facilitate making changes in the Lay Gears, we have provided two change places instead of one. Formerly it was the practice to change the gear on the end of the Reversing Shaft or the one between the Reversing Bevels.
In order to bring the change gears into a more convenient position and at the same time increase the range, we have introduced two additional spur gears. One of these is now the regular change gear, and is on a stud carried by an adjustable Quadrant Bracket. The short shaft carrying the bevel gears is now in a horizontal position instead of vertical.

Besides providing for two change places, this improvement dispenses with the Back Cross Rail and allows free access to the main gearing.
Any part of the gearing can be taken out and replaced with ease.
There is no longer any necessity of changing any bevel gears. There are two spur gear changes, either of which may be used and which give a very wide range. The entire arrangement is very simple and convenient.

Other sizes of Spindles, Long Collars, Bobbin Gear Tops and Rolls will be supplied when necessary.
DRIVING PULLEYS are usually 16 in. dia., 3 in. face.
