BURNER-'SUPPLY 1 f andy useful `Improvement in lBurner-Supply invention; and

Connections, of which the following a full, clear, and exact description, reference being had to the accompanying drawings.l

This invention relates kto oil burners, and more particularly to an Aimproved form-of connection whereby -such burners may` receive liquid fuel from their supply pipes and which will. enable such .burnersf'to be conveniently applied to andreinoved from their `supply pipes while providing a particularly efficient and leak-proof connection' between the burners and the pipes.

The invention shown herein is adivision ofvmy application #462,77 5 iledNover'n'ber 16th, 1908 which, in turn, isa division of' my Patent #908,997, issued January ,5th, 1909.

Generally speaking, theinvention may lbe dened further as'consistilig 'of the epmbinations of elements and parts embodied in the claims hereto yannexed Iand illustrated, in one exemplification, in the drawings form? ing a part hereof, vWhereilnlj Figure 1 represents a vertical sectional view' taken through a 'burner having; my invention applied thereto; Fig. 2 represents a detail, partly in section and partly' in 'eleva-v tion, of the lower end of a burner and shoW- ing the connection bettveen the saine andthe supply pipe; F' 3 is afdetail in plan of my 'gi 4 a detail in perspective of a portion ofthe same; v The burner shown hereinA is'substantially' `ident-ical .with that-,of my Patent #908,997

The snpplypipe 1is provided, within-seat,'with a threaded l'ower end 30 of the nipple'.

' 'In ordertoj secure thepar'ts thusdescri'bed to thesupplypipe, a 'li-'shaped strap. is. ein- 4'played consisting of-a :base land two' side .'m'einbers 33which may .be connected at the out-turned lower ends 34 b meansof a loop 3 5 applied thereto,- as shown in Fig. 2.

Through a threaded 'aperture l36 in the upper end .or base 37 of tliestrap thereextends ar- -short bolt 38, the lower pointed end fwhereof engages a seat formed in the top ofthe-con'- nection 24. A nut 39 is vIitted'within the .upper portion' of the Astrap and receives the.

bolt 38.Y This nut is held against rotation .bythe strap, whereby, on rot'atingthe bolt, thestrapma'y be loosened or tightened.

l As reviou'sly stated, the washer 29 is ofl material which will be compressed by tightening the bolt 38. The inaterial which` I prefer to .employ for this purpose is lead.

v'nula-r space Iiil'i'plef 30 and against' the seatwhich sup-.- ports the lflange, also 'upwardly between4 the sleeve, and the reduced lower end 27 of the4 connection 24 and between the nipple 30 and `On .tightening up the bolt 38, this lead is V"compressed and .is squeezed through the anbetween the flange 28% and" the such end',v ,the washer being prevented from spreading 'laterally by means of 28, which may be ofsheet metal. This construction provides an extremely eiiicientconnection' between the sup 1y pipe. and' the burner. 4-It -is not necessary to take any especial pains to provide' la :smooth seat in the recess 32 for the connection 24, `as the lead washer will accoinmodateitselfto any" irregularities of surface.. Furthermore, the

4manner in which the' lead flows, under compression, along'the outsideand the inside of i the'reduced' lower end 27 of the connection,

insures a tight joint at this place.

A eat advantage `in this construction 're'- sides in the'- fact that it dispenses with the use'of. a soldered joint,enablingl the pipe to be tinnedand lacquered 'before connecting the burner thereto without producing 4the discoloration ofjth'e tin 'and lacquer coatings on the pipe which would result from solderin `the' burner connection'thereto.

ig-Iaving thus described my invention, what I claim isz- 1. The combination .witha' pipe having an aperture in the wall thereof,'of a side branch :connection comprising a fitting 'having a" tubular projection, a nipple inserted into' said aperture, a washer of compressible m'athe sleeve' .termi-surrounding said nipple, a sleeve in- Aclosing'said washer, said sleeve being of greater diameter at one end than the end. of saidv'projection to receiv'ewsaid projection therewithin and having atfits opposite end- .an inwardly projecting flange of greater internal diameter`- than the-external diameter of the adjacent portion of said nipple, and lmeans for forcing the end of saidprojection 4 against said washer.

' l 2. The combination with a pipe having an aperture in'theiwali thereof, of a side branch connection comprising aitting having a tubularprojection, a l n1 ple inserted linto said aperture and into ,the ore of the tubular projection, a washer of compressible matcrlal surrounding said nipple, a sleeve 1ncloslng said washer, said sleevebeing yof .greater diameterjat one end than the end of said projection' to' receive said projection therewithin and -having at 'its o posite end -an inwardly projecting flange o greater in-l ternal diameter-than the Aexternal diameter of the adjacent'portion of said nipple,and l means for forcing the end of said projection against said washer. i

V3. The combination with a pipe having an aperture inthe'wall thereof and a seat surrounding -said aperture, of aside branch connection comprising-a fitting having a tubular projection, a nipple having one end fitted 'into said aperture, va' washer of corn- 'threaded aperture in the wall thereof and a seat surrounding saidaperture,- of a side branch connection comprising a fitting having tubular projection, a nipple hav-V ing. one end threaded to fit said aperture', a washer of coinpressible material surrounding the nipple', a sleeve inclosing said washer and of greater diameter than the end of the tubular projection to receive such end therewithin, and havingits end opposite said projection provided with an inwardly projecting `lange the internal diameter whereof is greater than'the external diameter of said nipple, and'means forclamping the washer 'between 'the endof said projection and said seat.

5. vThe combination with a pipe having an` aperturein the 4wall thereof, of a side branch connection comprisinga fitting having av tubular projection, a nipple having a edge near its outer end, a washer of compressible material surrounding the jnipple and oia diameter to receive thereon the end -of the tubular projection, a, sleeve inclosing said washer andhav' one of its ends pro-` vided 'with an inwar' ly projecting flange the internal diameter whereof 1s greater than the external diameter of said nipple, and mean for clamping Said fitting to said-"pi e so as to -compress said washer between te end er the projection and the portion of the pipe surrounding the apert 6. The combination with, a-pipe'having a 'threaded aperture in the wall thereof v and a seatlsurrounding said aperture, of aside branchvconnection comprising a fitting having a tubular projection',- a nipple having one end threadedA to vfit, the 'thread off said aperture. and 'its opposite end "enlarged to enter the bore of sind projection and being of. substantially the same external diameter as the bore of saidprojection,l agrwasher'lof lsaid washer between said compressible material surrounding said nipl its opposite end an inwardly projectingiange of greater' internal diameter than the external diameter of the adjacent portion of said nipple.v theu-nthreade'd end of said nipn ple projecting' beyond 4 the adjacent surface' of said washer, and means for clamping said fitting to said,l pipe so' as to compress projection and said seat.
