PATENTS ACCEPTED, 
SHEEP-SHEARING Macurne; Batancep Currer Pressure.—Class 36 (18 
Figures)—5998: John Kerwin Stewart, of No. 158 East Huron street, Chicago, 
Cook County, Hlinois, U.S.A.“ Improvement in the Construction of Clippers 
or Shearing fools.” Dated 7th May, 1901. (Drawings, 10s.; specification, 
17s.) To obtain equality of pressure on the three fingers of the upper cutting 
comb, notwithstanding its flexibility and other irregularities, the pressure of the 
floating forked lever upon the two outer fingers is given by a screw which reacts 
on the main rocking-bar to which the central lever is attached, so that the total 
pressure is suitably divided, and all other elasticity is avoided in the action; a 
laterally rockable pivot for the floating lever causes equal division of pressure 
on the outer fingers. (7 claims.) 
ToorneD Drum Cuntivaror.—Class 28 (2 Figures)—6024: Samuel 
Henry Wilton, soap manufacturer, of West street, Mudgee, in the State of 
New South Wales and Commonwealth of Australia, Thomas Wilton, farmer, 
and John Wilton, farmer, both of McDonald Creek, near Mudgee aforesaid. 
“An Improved Roller, Digger, Pulveriser, and Cultivator.” Dated 28rd May, 
1901. (Drawings, 10s.; specification, 5s.) This has a cart. body with central 
pole and draught-bar. The wheels have perforated rims to which segments can 
be bolted, forming a cylindrical drum extending from wheel to wheel the full 
width ; these segments carry sharpened teeth or tines bent in the direction of 
an involute to the drum so as to penetrate the ground normally and come out 
with a lifting action ; scraper teeth at the back clear off clods. The segments 
of the drum are divided spirally, and are made removable for convenience of 
carriage (in the cart body) from place to place. A lateral arm carries a mould- 
board that may be depressed when required to form ridges or earth-up rows of 
plants. (2 claims.) 
Bockxer Pump-starteR FoR WINDMILLS.—Classes 69, 86, 91 (4 Figures) 
—6016: James Thomas ‘Tylor, of Warwick, Queensland, traveller and 
machinery expert. ‘An Automatic Device for throwing Windmillsin and out 
of Gear.” Dated 17th May, 1901. (Drawings, 3s. 6d ; specification, 5s.) 
A bucket is hung to the starting and stopping wire of a windmill, and is so 
connected to the storage tank that when the tank is full the bucket also fills 
and in falling stops the mill; when the water-level falls the bucket empties and 
the mill again starts, Figure 1 shows a flexible pipe from the bottom of the 
bucket to the tank; Figure 2 shows the tank filled through the bucket, the 
bottomjof which is connected by a flexible pipe to a float-valve in the tank ; and 
Figure 3 shows a syphon connection. (8 claims.)
