AApplication led November 15, 1909. Serial No. 527,975.
To all whom it may concern:
Be it known that l, HERMAN C. Fnrrz, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Nozzle-Reinforcing ll/.leansg and l. hereby declare the following to be a full, clear, and exact description of the invention, such as will en able others skilled in the art to which 1t pertains to make and use the same.
This invention relates to improvements 1n nozzle-reinforcing means whereby a nozzle which is screwed into a pipe or other fluidconducting nozzle-supporting member 1s around its inner end-portion and externally of the nozzle-supporting member reinforced and braced from the nozzle-supporting member.
The primary object of this invention is to materially reinforce and brace the inner end-portion of a nozzle which is externally screw-threaded at the said end and screwed into a pipe or other nozzlesupporting member employed in conducting fluid to the said nozzle.
Another object is to prevent screwing of the nozzle too far into the pipe or nozzlesupporting member.
Another object is not only to materially reinforce the nozzle around its inner endportion and externally of the nozzle-supporting member, but to form a sightly trimming around the said end-portion of the nozzle next externally of the nozzlesup* porting member.
With these objects in view, this invention consists in certain features of construction, and arrangement and combination of parts, hereinafter described, pointed out in the claim, and illustrated in the accompanying drawings.
ln the said drawings, Figure 1 is a top plan of a nozzle attached to a pipe and reinforced in accordance with my invention. Fig. 2 is a vertical section on line 2 2, Fig. l, looking in the direction indicated by the arrow. Fig. 3 is a horizontal section on line 3 3, Fig. 2, looking downwardly.
Referring to the drawings, A indicates the fluid-receiving inner end-portion of a nozzle to which fluid is to be conducted by a pipe or hollow member B which supports the nozzle and is provided interiorly with a passageway Z2 for conducting fluid to the nozzle. The nozzle-supporting member B and the nozzle are arranged substantiallyv horizontally and at a right angle to each other. The said end-portion A of the nozzle is screw-threaded externally and screwed into a correspondingly screw-threaded aperture l() which is formed in the pipe or nozzle-supporting member B at one side of the nozzle-supporting member. rlhe said endportion A of the nozzle is provided externally and a suitable distance from the pipe or nozzle-supporting member with an annular shoulder a which faces in the direction of the said nozzle-supporting member. rlhat is, the shoulder a is spaced from but arranged in suitable proximity to the nozzlesupporting member. A spring-collar D, which preferably consists of a single metal stamping, is interposed between said shoulder a and the pipe or nozzle-supporting member B and flares or spreads from the said shoulder toward the nozzle-supporting member and is contoured to abut against and fit the nozzle-supporting member all around the nozzle. That is, the collar D is gradually enlarged transversely of the noz-A zle in the direction of the pipe or nozzlesupporting member and all around the nozzle slopes away from the nozzle in the direction of the nozzle-supporting member. Ilhe collar D is preferably provided at its outer or transversely smaller end and internally with an annular flange CZ which surrounds or extends circumferentially of the nozzle and is engaged by and forms an abutment for the shoulder a.
By the construction hereinbefore described it will be observed that the collar D forms a somewhat yielding abutment for the shoulder a of the nozzle and cooperates with the said shoulder in forming a stop for limiting the screwing of the nozzle into the pipe or nozzle-supporting member.
lThe springcollar D is clamped by and between the shoulder a of the nozzle and the pipe or nozzle-supporting member B and thereby placed under tension. That is, the nozzle is screwed far enough into the pipe or nozzle-supporting member to cause the shoulder a of the nozzle to somewhat clamp the collar against the nozzle -supporting member so as to place the collar under tension and thereby very efficiently brace the nozzle from the nozzle-supporting member and materially reinforce the screw-threaded innerend-portion of thexnozzle all around the nozzle. It Will be observed also that the collar D forms ,a sightly trimming around the nozzle next the'pipe or nozzle-supporting member. 4
By my improved construction it will be observed ,that the spring-collar D not `only braces and steadies the nozzley and thereby prevents tipping of the nozzlelaterally in any direction, but, by bearing against the shoulder a, locks the nozzle in position vand thereby prevents unscrewing of the nozzle Without the application of considerable force. Y
What I claim isz- VThe combination, With a nozzle-supporthr ingfmember havingV a screw-threaded aperture extending to the exterior of the mema ber, and a nozzle screw-threadedexternally of its uid-receiving end and screwed at the said aperture into the nozzle-supporting member, which nozzle is provided externally `With a shoulder which extends'circumferentially of the nozzle and is spaced from and faces the nozzle-supporting` member, of a spring-collar interposedbetween the said shoulder and the nozzle-supporting member,
ywhich collar is under tension and bears nesses. Y
