Show TH 4 PRINCIPLE O SCIENTIFI MANAGEMEN As a result of further study, after the bricks are unloaded from th cars, and before bringing them to the bricklayer, they are carefull sorted by a laborer, and placed with their best edge up on a simpl wooden frame, constructed so as to enable the bricklayer to tak hold of each brick in the quickest time and in the most advantageou position In this way th bricklayer avoid eithe having to tur the brick over or end for end to examine it before laying it, and h saves, also, the time taken in deciding which is the best edge an end to place on the outside of the wall In most cases, also, he save the time taken in disentangling the brick from a disorderly pile o This "Pack" of bricks (as Mr. Gilbreth calls hi the scaffold loaded wooden frames) is placed by the helper in its proper positio on the adjustable scaffold close to the mortar box We have all been used to seeing bricklayers tap each brick afte it is placed on its bed of mortar several times with the end of th handle of the trowel so as to secure the right thickness for the joint Mr. Gilbreth found that by tempering the mortar just right, th bricks can be readily bedded to the proper depth by a downwar pressure of the hand with which they are laid He insisted that hi mortar mixers should give special attention to tempering the mortar and so save the time consumed in tapping the brick Through all of this minute study of the motions to be made b the bricklayer in laying bricks under all standard conditions, Mr Gilbreth has reduced his movements from eighteen motions pe brick to five, and even in one case to as low as two motions pe brick He has given all of the details of this analysis to the profession in the chapter headed ‘"Motion Study,"" of his book entitle "Bricklaying System," published by the Myron C. Clerk Publishin Company, New York and Chicago; E. F. N. Spon, of London An analysis of the expedients used by Mr Gilbreth in reducin the motions of his bricklayers from eighteen to five shows that thi improvement has been made in three different ways First. He has entirely dispensed with certain movements whic the bricklayers in the past believed were necessary, but which careful study and trial on his part have shown to be useless Second. He has introduced simple apparatus, such as his adjustabl scaffold and his packets for holding the bricks, by means of whic with a very small amount of cooperation from a cheap laborer, h entirely eliminates a lot of tiresome and time-consuming motion which are necessary for the bricklayer who lacks the scaffold and th packet Third He teaches his bricklayers to mak simple motions wit |
