(f e give here, u'eek by week, a terse description of »uch of the many 

 ]. inventions us ux think may be of use to our readers. Where it is 

 '.'. possible, the »iM»(jfr of the patent is quoted, to enable those who 



desire fuller information to procure the specification from, the 

 "patent OjSice in Cursitor-street, Chancery-lane. We shall, geiie- 

 ' rally speaking, confine ourselves to tlie more recent inventions; but 



it often happens that an article comes under our notice which, 



although not quite novel, is toorthy of mentio'.

revolving rollers to the collectors, which receive and compress i' 

 against weighted lovers ; and when the required quantity of straw 

 is collected to balance and movo the weighted levers, the binding 

 mechanism is thereby started, the pair of binding arms from below 

 the collected straw rise up, enclose and bind it with two bands, 

 while the truss is under compression. The Biit's of the trnases m»y 

 be regulated to suit different requiremeutg. 



RUDDEB FITTINGS. 

 [Patent No. 10,575. 1881.]— This invention, by Mr. H. 

 Eniannel, provides the means of instantaneously shipping or 

 unshipping the rudder, by day or by night, while a boat is afloat or 

 under way. It is manufactured throughout of non-oxidising met&l, 

 and the barrel is hard drawn. Those who hare had any experience 

 of sailing can understand the difficulty of shipping and unshipping 

 a rudder in the water and more particularly m the dark attached 

 b\ the ordinary method of pintles and eyes Mr Emannel a plan 

 18 t J fix a slotted barrel to the transom of the boat ih beu of the 

 usual gudgtons and as the rudder carries between its straps a 

 continuous spindle the latter only requires to be inserted in the 

 bore of the barrel to at once fall into working position by the focce 

 of its own weight H i -' i -w J iv^n-^^ -.aui i •

Tins straw trusaer will bind into Bhiivea aut nmticiUv the whole 

 of the straw as it leaves the shakers of a threshing machine It 

 requires no attention lioyond the removal of the sheaves as they 

 are delirered from the binder ; and except the cost of the twine, 

 saves the labour of the several men necessary for binding the 

 straw into sheaves by hand. The average cost of twine required 

 to bind a ton of straw is a shilling, which is not more than the 

 expense in labour of making straw bands to bind the same weight 



The machine is easily understood and readily managed ; it is 

 very portable and compact, and being mounted on three travelling 

 wheels, is rendered convenient for the application of shafts, he 

 or bullock pole for draught, or it may be coupled to the back 

 of a threshing-machine by a suitable draw-bar, and removed fi 

 place to place in this wav, either by horses or a traction-eng 

 No fixing or securing to" the thresher is necessary for work, the 

 trusser being simply wheeled to the machine, and the driving-cl-- 

 afctached. 



The straw on leaving the shakers of the thresher slides down 

 the side of the hopper of the troaser, and is carried forward by the 



ST MR CLIPS 

 [Patent ^o 12 014 1884 ]— These new stair plates or nozings, 

 patented by Mr F W Hembrv, "Newgate street, London are » 

 combination of metal-gauze and India-rubber, and are claimed to 

 be superior to the old form in brass and iron. The metal-ganze is 

 first placed upon a backing usually of a thin rubber cloth-like 

 texture, which is coated thickly with rubber cement. Above (jiis 

 wire gauze or perforated metal plate is again spread a quantity of 

 cement, which not only passes through all the holes of the meah 

 but also is the means, after vulcanization, of firmly securing the 

 rubber on the surface. This being bent to its proper form, and 

 vulcanized becomes one of the best protections against falling or 

 slipping, and prevents the wear and noise on stau-s. 



TiiE Panama Caxas.— At the close of 1884 the Panama Canal 

 Company had no less than 20,239 agents and workmen in its em- 

 ployment. The duration of each working day has been fixed at 

 ten hours, viz., from 6 to 11 a.m. and from 1 to 6 a.m.
