IMPROVEMENT |N HOSE-PIPE NoZZLEs'.
Specication forming part of Letters Patent No. 137,881, dated April 15, 1873; application filed March 17, 1873.
To all whom it may concern:
Be it known that we, BAYARD A. BERRY- MAN and ALANsoN B. WAKEEIELD, of the city and county of St. Louis and State of Missouri, have invented a certain Improvement in Nozzles for Hose-Pipes, of which the following is a specication:
Ourfinvention consists in rifling or forming spiral creases in the interior of a hose-nozzle, and screwing upon the outer end a smoothbore tip, the purpose of this construction being to impart a rotary motion to the Water passing through the nozzle, which enables the Water to be forced in a solid body from the nozzle Without becoming broken or spraying; the
' object of the smooth-bore tip being to collect the water and cause it to be discharged in a cylindrical body. Our invention also relates to forming an enlargement or chamber between the grooved and smooth parts ofthe nozzle, in which the water rotates before it enters the smooth-bore tip.
Figure lis a longitudinal axial section. Fig. 2 is a transverse section of the smooth-bore tip at line .o a. Fig. 3 is a transverse section of the ried portion of the nozzle at line y y.
A is the barrel of the nozzle of any suitable form' and degree of taper. The barre-l is formed with a number, two or more, of spiral creases,
a, extending forward to the chamber B. The interior of the tip C is made tapering and smooth, and is preferably made to screw upon the part A, and a gasket, c, being interposed at the union of the tWo parts to prevent leakage. VThe barrel A is recessed at B to form an annular chamber, in which the Water has free rotation, and from .which it enters the smooth-bore tip G in a solid body having rotary motion.
What we claim is- 1. The barrel A formed with spiral creases c, as and for the purpose set forth.
2. The barrel A having spiral creases a, in combination with the smooth-bore tip C, as and for the purpose set forth.
3. The combination and arrangement of the barrel A, spiral creases a, and tip C with the chamber B, as and for the purpose set forth.
