Pneumatic CanE or WEED Currrr.—Classes 80, 66—(2 Figures)— 
6292: Ralph Herbert Paul, of Brisbane, Queensland, Judge’s Associate. “A 
Tool for Cutting Sugar-cane, Prickly-pear, and other Vegetable Growths.” 
Dated 30th October, 1901. (Drawings, 7s. 6d.; specification, 12s.) A special 
tool of the type described in Specification No. 5561. The pneumatic percussion 
motor is of the valveless type and is grasped by a hollow lateral handle; the 
chisel or hoe-like cutter has a polygonal guide-stem to prevent rotation ; the 
body has a prolonged axial shaft hinged to an arm-plate for strapping against 
the operator’s arm near the elbow; the cutting tool may havea prolonged stem 
for cutting cane close to or below ground without stooping, and for reaching 
amongst cactus plants ; the exhaust air passes through the hollow handle and 
is discharged as a cooling jet against the operator. (9 claims.) 
ADJUSTABLE Harrow.—Class 28—(9 Figures): The harrow has one or 
more sections which carry spring (or other) teeth on cross-bars that may be 
adjusted by a lever and rack on the main frame. The front end is carried by a 
central shoe or skid, which may be adjusted for height by changing bolt-holes 
on the draft-bar. A pair of carrying wheels at the back corners are attached 
to arms on a rocking cross-bar, with shifting lever and rack, the arms being 
adjusted by serrated surfaces, through which the connecting bolts pass ; this 
rocking cross-bar also carries a row of trailing teeth that may be adjusted for 
depth by rocking the bar. (4 claims.) 
Transport ArracuMENnTs FoR IwpremEnts.—Class 28—(4 Figures)— 
6143: D. M. Osborne and Company, of No. 24 Genesee street, city of Auburn, 
county of Cayuga, New York, U.S.A., manufacturer (Assignee of Charles

“Improved Transport Attachments for Harrows.”’ Dated 29th July, 1901. 
(Drawings, 40s.; specification, 8s.) To enable cultivators or other implements 
of any construction to be lifted clear of the ground on to travelling wheels, 
the said wheels are mounted at the ends of a deep-cranked axle, the transverse 
part of which is journalled across some convenient part of the cultivator frame. 
During the use of the cultivator the legs of the cranked axle with the wheels 
are turned up, but for travelling are turned down and linked to the cultivator 
by suitable catches; by using the pole as a lever the operative parts of the 
cultivator are raised and brought forward so as to be fairly balanced over the 
axis of the carrying wheels. (5 claims.) 
ComsBineD Deprnarory AND Fire Branp.—Classes 08, 36—(11 Figures) : 
To enable the brand to penetrate through wool or hair and actually touch the 
skin, the outlined surface is constructed of pointed combs attached to the 
surface, with peforations in the surface near the roots of the comb teeth, so 
that a depilatory or colouring composition may trickle down the teeth to the 
skin. he depilatory composition is composed of equal parts of sodium sul- 
phide, slaked lime, resin, and boiled linseed oil incorporated to a solid waxy 
cake. The colouring matter is similarly a waxy cake of equal parts of resin, 
linseed oil, and colouring matter. The waxy material is placed in a metal pan 
or case attached to the back of the brand; and may be heated intermittently by 
hot sand or melted lead, or may be continuously heated by a special vapourising 
oil-burner of the “Primus” type so arranged as to act in any position, and with 
a reservoir pipe (with stopcock) passing through the handle so that the 
reservoir may be refilled without cooling the burner; the main oil-vessel is 
also made of a curved shape to screen the handle from the radiant heat. (15 
claims.)
