PAINT BURNING AND SCRAPING TOOL Filed NOV. 6) 1940 Patented Aug. 10, 1943 PAINT BURNING AND schermo-Toon n Jescph Si Fagan, Ing1ewood,;,Calif f Y y atpicaei'gaiyovmbers, 1940", seriarnastirslzv c f t i ciaim-. (01; 15a-#reif Y t My invention rel-atesto' a paint burning. and

and futher ,gto prov-idea' tool'having'means'ior eieciing'a'v thorough mixtur'ejof airwith' theA gas as it passes through the tool' and' discharges' fromv the forward portion thereofv over the scraping blade.
A further object' of my invention is, to pro-vide a paint burning and scraping tool of the character referred to wherein the gas flame issuing from therburner that is located rearwardly lof the scraping blade is projectedrforwardly over Y the blade without directly impinging the same, so as to burn and soften the paint several inches in advance of the sharp edge ofthe blade,;there by adding materially to the efciency of the tool in burning and scraping paint.
A further object of my invention is, to provide- Y a paint burning and scraping tool wherein the scraping blade is formed integral with the forward portion of a hollow member that functions as a combined mixing and combustion chamber for the gas and air that pass through the tubula in plan and said vblade havingfal transversely dis.- s.
handle of the tool.
With the foregoing and other objects in Viewi my invention consists in certain novel features of construction and arrangement of parts lhatf will be hereinafter more fully described and claimed and illustrated in the accompanying` drawing in which:
Fig. l is a plan view of a paint burning and scraping tool constructed in accordance with my i invention. I
Fig. 2 is a longitudinal section taken on the line 2 2 of Fig. 1. Y
Fig. 3 is an enlarged cross section taken on the line 3 3 0i Fig. 1.
Fig. 4 is an enlarged cross section taken on the line 4 4 lof Fig. 1. y
Fig. 5 is an enlarged cross section taken on the Y line 5 501 Fig. 1.
Referring by numerals tol theY accompanying ment .of my invention, I designates a Ine-tal tube, on the rear portion of which is mounted a handrawing which illustrates la preferred embodidie li shaped so as to be conveniently :grasped in the hand of the user of the Ytool and detachably mounted on the rear end of tube Ik!) is a nipplev i2 having a centrally arranged'chamber I3 and the Wall of the nipple surrounding said lengitudinally disposed-Y duct Y' 'chamber being provided( ,plurality .of an inlet epeningst I4..` v v end, of a. valve housing lthfrcvuglll W ing rs and, Saddvaive-beiea prende-dante a dief l. metricallyarranged. portT ij that yis. fadaptedv I Y e1outer: end'.of
coincidefwith the duct-lli.i KVTh thevalvelicarries a handle 19.
vA duct' 2U; preierabl'y'affie leads jfrorn a" suitablefso site the en d that enters thenipple l2.
The 'forward end ofA tube. l0 is screwseated in a wall 2lv`that closes the rear end of a-jshortrtu-y bular member 22, the chamber withinwhich functions as .a .combinedcombustion chamber and a g gas and airmixing chamber. v Formed" through the wall 2l around tube I0 is a series "of airinlet openings 23. VFormed through the Vwall of "tubular member 22 nearits lrear endis a .series of airinlet apertures24.`4 I v Formed integral with the lower portion .of
the forward endA offmember 22is therear. end of a forwardly y.and downwardly projecting blade-1 25 that is substantiallytriangular when viewed posedfairly sharp forwardedge 25. Y The forward end ofthe upper portion of the wall of tubular member is curved downwardly as designatedv by z..
2'! towardfthe rear portion of the blade Y25 and such construction producesa substantially oval opening 28 'directly above the rear :portion ofr y blade 25 and the width of which opening issubv g stantially greater than its height.
VThus the jet of Vflame issuing from the comy binedcombustion and mixingA chamber 'within Amember 22 is caused to now-forwardly, over the inclined blade 25 so as to strike the painted surface on which the toolr is beingused, several.
inches in front-of thev sharp edge of theblade.
'I hus the jet of llame issuing fromntheopening `28 has much greater widthv than thickness and as a result, an area of considerable width.
on the' painted surface immediately Vin frontV of Ythe edge ofthe Vblade is impinged by the' flame l and consequentlyY heated and softened.
Y rWhile my improved tool is in service, gas passes Y Y lfrom duct 2i) through the open valve and this 4gas'discharges from the forward endof `the valve housing'into chamber" I3-and` from said chamber the gas passes forwardly through tube I0. Inasg much as the gas is under a certain degree of pressure, its discharge through the chamber I3 Screw seated. inV the rear end-.of nipple: l .io-ne;l ch S ,fQr-med substantial yarea of the pa Y j ately in frontV of the blade;
intoL tube I0 will draw air into chamber I3 4through theopenings I4, which air will mix with the gas'passing through tube I0, and this mixture of gas and air will discharge and expand in the chamber within tubular member 22.
Additional air to support combustion of the mixture of gas and air entering and passing through the chamber Within member 22 will be drawn through the openings 23and' 24 in the rear portion of member ZZ'and the resulting mixture when ignited will dischargein the 'form of a fiat flame from the opening 28 at the forward end of member 22 and which flame will impinge and burn the paint on the surface immediately in front of the edge of blade 25.
Immediately after the paint has beensoftened by the flame, the tool is moved forward so that the sharp Vedge of the blade willv engage and remove the softened paint, thereby accomplishi' ing the desired results.
My improved paint burning andscraping tool-V is particularly effective in servicer inasmuch as the shapeof the opening 28 at the forward' end of the combined mixing and combustion chamber withinA member 22 natten's the name'as it disflatten'ed fiameimping'es against and burns a inted surface immedi- Thus fit will be` seen that `I have provided a paint burning and: scraping tool that is' relatively simple in construction;"inexpensive of vwhich is set forth in the appended claim.
I claim as my invention:
In a paint burning `and scraping tool, a hollow cylindrical member .provided with a rear wall,
' a blade formed integral with and projecting forwardly and downwardly from the forward lower portion of said hollow member, there being a single oval shaped jet opening formed in the forward end of said hollow member, the major axis of which oval-shaped opening is horizontally dischargesfforwardlyover 'the blade 25 and said :posed andthe bottom of said opening coinciding withatheupper surface of the rear portion of the blade so as to direct the single wide jet of burning gaseous fuel that passes through said opening forwardly to strike `the surface that is being acted upon, forwardly from the front edge of the blade, a gaseous fuel supply pipe connected to the' vcentral Vportion of the Wall closing the rear end of said hollow cylindrical member, and there being a plurality of air inlet apertures formed in said rear Wall around the gaseous fuel supply tube connected thereto.
