Table A gives the result of the application of an entirely new test vibram five fingers to threshing-machines, one, viz., which registers the amount of force required to drive the machines when empty. Table B records a further attempt to ascertain the proportions in which the amount of draught given in column 9 of Table A should be apportioned between the horse-works and the barn-works of the respective machines. It will be observed vibram fivefingers that the number of the machines tried is reduced from 16 to 5. This arose from the trial in question heing a new suggestion which occurred to the consulting engineer at a period of the proceedings which did not admit of its being extended to more than a very limited number, Mbt shoes clearance those being selected which had acquitted themselves the best in the previous trials.The mode of conducting this trial was as follows:—The machines were driven by steam, and the power registered which was required to drive them empty. This gave the friction vibram five fingers kso of the barn-works alone, and is recorded in col. 6. The friction of the whole machine (?. e., both horse and barn works) is shown in col. 5, and is in fact identical with col. 9 of Table A, the power being given in stones in one case, but expressed in the equivalent horse-power in the other. The difference between these two (see col. 7) gives the friction of the horseworks. This method does not pretend to absolute accuracy, but it furnishes vibram five fingers sale an approximation which will in the opinion of the reporter do much to improve the construction of these machines. Its importance will be best seen by comparing two five fingers shoes machines in which the whole friction was about equal, but where it was due in very different proportions to the barn-works and horse-works respectively. The machines of Messrs. vibram five fingers shoes Garrett and Woods furnish an excellent illustration of this point, the whole friction being in these cases 2-78 and 2"81; the friction of the barn-works being, however, 2-07 and -46;'whilst that of the horse-works was "71 and 2'35. It is not an improbable supposition that both of these makers on their return home might have endeavoured to reduce the draught of their machines, and had the whole friction onlv been ascertained, they would have had no clue to mbt sandals the particular part which was in fault. |
