(01. 169-37) ‘ ,- This invention relates to improvements in‘ cular area being doubly protected,'as it were, sprinklers. More especially it has to do with a for there is of ‘necessity a large overlapping of sprinkler capable of distributing its discharge these circular areas. As a consequence it several over a substantially ‘rectangular area. 5 '- - sprinklers are opened upon the occurrence of a I Sprinklers now in common use‘ distribute their ‘ ?re there is bound to be an unwarranted water» 5 discharge over a circular area. When installing damage due to this overlapping alone. a sprinkler system employing such sprinklers " the latter must be so located with respectlto one an-v The present invention enables the’ shape of area served by each sprinkler to be changed from . other that their combined discharge covers all 0 the area, to be protected. This requirement, coupled with the circular area serv d by each sprinkler results in a large overlapp of area . which is not only unnecessary but is also undesir- ' able for it leads to excessive discharge and need-> 15 less water damage. It is anobglect of this invention to provide a a sprinkler which will enable the aforesaid over-, lapping to'be reduced to a necessary minimum and which will permit a less quantity of water to 20 be discharged from each sprinkler albeit the in tensity of precipitation is no less than is now deemed suitable. Clearly it the proposed sprinkler actually discharges a smaller quantity the customary circular shape e to one which is substantially rectangular. - In the particular ex- '10 ample disclosed for purposes of illustration this area “is shown as an approximate square I. The diagonal of the latter is substantially equal to the diameter of the circle previously. covered, there being" a small but ample overlapping of the 15 edges of these square areas to avoid vany un-, reached spaces. Since the area of each square served by ahead is about seventy per cent of the area of the corresponding circle, previously covered, it is possible, with seventy per cent of 20 the quantity of water heretofore discharged from each head, to sprinkle the ‘square area with the ' same intensity of precipitation as before. ‘In other words, due to the almost complete-elimina tion of overlapping areas and the great reduction 25 The best mode in which I have contemplated .' in area actually served by each head the entire ‘ of water it must follow that the water damage is 25 correspondingly reduced. - v ‘ -. applying the principles of this invention is illus trated in the accompanying drawing but’ it is area can be just as effectively sprinkled as here tofore but with a saving of atleast thirty per cent intended that the patentshall cover by suitable Y of ‘the quantity of water. ‘ Consequently, when 30 expression in the appended claims whatever vthe sprinklers under the improved arrangement features of patentable novelty exist in the inven of distribution open for discharge there is neces ' tion In Figure disclosed. the drawing, 1 represents the plan 7 view ' of vanarea ‘ ,_ to _ 35 be protected, with the unit area served by each improved sprinkler indicated by the heavy dotted sarily a'marked saving in water damage.
