Eureka非交叉式接头耦合。

几乎与用于防火的软管一样重要的是与它有关的耦合。曼哈顿巴克莱街13号尤里卡消防软管公司生产的非交叉线程联轴器。纽约，已被作为标准采用，并以不寻常的护理和建筑的细节进行了改进，以使其现在适合努力和可靠的服务，并为建立连接而设施。所有这些都是由青铜制造的，除非另外需要，否则所有螺纹的弧线弧都可以在外部切断，以促进耦合并防止在软管连接时穿过线的可能性制作。这些耦合完全来自新的。第一质量的金属，由电解铜和高级锡组成，仅具有尖峰和铅的混合物，即可使金属最好地适应耦合生产。即使是在较便宜的磨坊和亚麻软管弧上，完全由相同的高级新金属制成，其散发器比例很大，其结果是用于使用目的的坚固而出色的金属。不使用旧金属或二手金属。因此，铸件不是多孔，虚弱或其他有缺陷的，尤里卡的铸造厂（•IRE HOSE Company在其位于N. J ..的工厂的工厂，是一款模型的型号，并且以各种方式，最新的所有方式，所有 the bronze and brass goods are made by day's work and under careful and expert supervision. Eureka couplings are made with threaded swivels, consisting of four annular threads cut male and female in the inner and outer parts of the swivel respectivelv. These threads are standard 60 " and of full depth. For them it is claimed that they give at least four times the wearing surface that the ordinary flanged lip swivel joint gives, and their V shape prohibits any possibility of jamming, the tendency of the joint being to free itself. The threads, swivel, washer-recess and waterway of these couplings are made at one setting of the part in a lathe. Consequently, they are perfectly true with each other. The couplings. therefore, go together without the slightest trouble. All swivel-lugs are carefully milled to a uniform size so that spanners may invariably fit. The hose sockets are made of ample length to permit the use of an expansion ring of good width, and so avoid any liabilityof couplings blowing off, as when short sockets and narrow rings are used. The Eureka sockets are made heavy enough, and of such tough metal that ordinary expansion will not expand the sockets at all. Rings are expanded by the use of an hvdraulic coupling machine, in which the amount of expansion presstire is recorded by hydrostatic gauges. The pressure required to affix couplings so as to withstand high pressure is predetermined, and, when couplings are being affixed, that prescribed pressure is applied. The Eureka couplings are made expressly to permit the use of adequate expansion-pressure without the slightest injury. The company’s couplings can be attached with any ordinary expander, without the use of any special appliances.
