Agricultural Patents. 
PATENTS ACCEPTED. 
Suare anp Foor-prece ror Stump-Jump Provens.—Class 28 (6 
Figures)—5664: John Shearer and David Shearer, both of Main street, 
Mannum, South Australia, machinists. “Improved Share and Foot-piece for 
Ploughs and other Cultivating Implements.’ Dated Ist September, 1900. 
(Drawings, 7s. 6d.; specification, 6s.) A. strong steel liner or foot-piece 
connects the special share to the stem to give strength for stump-jumping. 
The foot-piece is bent against the stem, to which one flange is attached by 
rivets or bolts, the other flange having a curved surface to suit the share and 
mould-board. The share-plate has the land side turned inwards and upwards 
to form a socket into which the foot-piece fits and becomes more securely 
jammed by collision with obstacles. (5 claims.) 
Destccatep Miik Propucts anp Apparatus.—Class 32 (7 Figures)— 
5903: Joseph Henderson Campbell, of Hotel St. George, borough of Brooklyn, 
city of New York, United States of America, chemist, and Charles Henderson 
Campbell, of corner of Oak lane and Ninth street, Oak lane, Philadelphia, 
Pennsylvania, United States of America, manufacturer. ‘‘ Improved Condensed 
cor Desiccated, Milk, and Process and Apparatus for Preparing the same.” 
Dated 22nd February, 1901. (Drawings, 17s. 6d.; specification, 26s. Gd.) The 
condensed and desiccated milk products prepared at temperatures below 72 
degrees C., which are capable of re-solution to normal milk, are claimed; the 
final product is a dry, pulverised milk flour. The desiccation is done at 
atmospheric pressure by subdivision of the milk in currents of air. In the first 
stage the milk is heated by circulating steam-heated water in through-pipes 
and a jacket, the milk being simultaneously agitated by warm or cool air-blast ; 
as the volume of the milk diminishes the level of the heating water is also 
lowered in the jacket and pipes. In the second stage the condensed milk is 
placed in a revolving drum and the hot air is projected against the film of milk 
carried over the upper part of the interior of the drum until the mass can be 
scraped out in a granular, pasty condition. In the third stage this is passed 
through a breaking hopper with hot air-blast, and then scraped through a sieve 
to the third revolving drier, which consists of a canvas rotating drum with 
central air-pipes projecting warm blast against the mass of powder turned over 
by the rotation. ‘The final product from this drying contains less than 8 per 
cent. of water, and may be ground to flour. Other products with wheat-flour 
and cocoa are mentioned. (20 claims.) : 
Cane Saw wirn Pneumatic Moror.—Class 30 (5 Figures)—5948: 
Alfred Joseph Lewis, of Burnett street, Bundaberg, Queensland, nuisance 
inspector. ‘A rotary Cane Cutter.” Dated 1st April, 1901. (Drawings, 
10s. ; specification, 2s. 6d.) A pneumatic rotary motor of any suitable ie: 
carries a circular saw secured on the motor spindle. The apparatus is held by 
a suitable handle, and the supply pipe drags along the field. Only one cane is 
cut or topped at one time by this tool. (1 claim.) 
Preumatic SeateD Provrston Caw.—Class 76 (8 Figures)—5880: George 
Lees, of No. 4228 Oakenwald Avenue, Chicago, State of Illinois, United States 
of America, packer. ‘“ Improvements in or connected with Sheect-metal Cans 
or Hawt aba for Enclosing Preserved Provisions or Food and the like.” 
Dated 5th February, 1901. (Drawings, 5s. ; specifications, 5s. 6d.) A sheet- 
metal canister for food products has a recessed rim on the cover and body into 
which a rubber ring is fixed by the air-pressure on the lid. The particular 
conformation of the joint is claimed. (8 claims.)
