PAINT REMOVING DEVICE.

Specification of Letters Patent.

Patented Oct. 7, 1913.

Application filed June 7, 1913. Serial No. 772,414.

To all'whom it may concern:

Be'it known that I,"MARKUs L. SPIRA, a

subject of the King of Hungary, residingat Cleveland, in the county of Cuyahoga and State of Ohio,'. have invented certain new and useful Improvements in Paint-RemovingD'evices; and I hereby -declare the following-to be-a-full', clear, and exact description of the' invention, such as will enable others skilled inthe art to which it pertains to make and use the same.

This inventionrelates to improvements in paint-removing devices, and'pertains more especially to a paint-removing device employed in removing paint from wood or metal.

The primary object of this invention is to produce adevice whereby burned paint can be removed from a painted surface before the burned and consequently blistered or softened and loosenedpaint has had a chance toharden;

Another-'objectis to provide a paint removing-device of the character indicated which can'- be"manufactured with facility at little cost:

Withthese'objects in View, and totheend of attaining-any other advantage hereinaften appearing;this invention consists in certain features of construction, and combinations and arrangement of parts, hereinafter described, pointed out in the claims, and illustrated in" the accompanying drawings.

In said drawings, Figure 1 is atop plan of' a rail and'shows my improved paint-removing" device in position for removing paintfrom one side surface of said rail. Fig. 2 is a sectionon'line 2-2, Fig. 1, looking in'the direction indicated by the arrow, but therail illustrated in Fig. 'Tis omitted in" Fig. 2. Fi'gL3-is a central section'of my improved paint-removing device and shows the la-tter in the position shown in Fig. 1. Fig-'4 is a transverse section on line 4-4, Fig.3, looking forwardlv.

My improved paint-removing device comprises a-meta-l blade'A for scraping the blisterjed' or burned .and softened or loosened paint from a painted surface. Said blade is adapted to extend transversely of the surface to be scraped, and in'Fig. l is-sh'own in position fdr scrapingpaint from-one side of the rail C. F ig; 1 showsmy improved paint-removing device to be moved in; the: direction indicated" by the *arrow 6'to scrapepaint from-"said rail. The'blade A is provided with two forwardly projecting arms a-which, as shown in Fig. 4, are arranged at opposite ends respectively of the blade. Said arms are therefore spaced longitudi- "nally'of'the blade A and are also spaced from the scraping-edge 7 of the blade. Said arms are connected together by a metal plate ,B. The blade A and the plate B are therefore" connected together, and said plate is adapted toengage with the head D of a paint burning nozzle, and said nozzle and said plate are "removably secured together as will hereinafter appear. The plate B and the connected blade A are preferably composed of a single-metal piece. The arms a areprefer'ably arranged at an obtuse angle to the blade A, and the plate B is arranged substantially at a right angle to and extends rearwardly from said arms. In the position of the paint removing: device shown in Fig; 1 to remove paint from aside of .a

rail there is no liability, of course, of scrapedoff paint accumulating in frontof the blade- A 'because' the scraped-ofl? paint will fall from the rail, nor is there any liability of theaccum'ulation of scraped-0E paint in front of the blade=in scrapingoif paint by a downward movement-onthe painted surface, but in scraping-painton an upward movement of the'paint-removing device the spacing of-"thearms a will be found not unimportantfto' permit 'escape' of the scrapedofi" paint between said arms and thereby prevent any'undue accumulation of scraped-off paint between the blade A and the forward end I of -'the paint-burning 1 nozzle.

The nozzle-head ID forms the forward portionpf the nozzle and rojects forwardly are spaeed'longitudinally' ofsaid edge and form "the outlets of'the chamber 8. Ob;

viousl-y saidedgefor-ms the forward or discharging end of the nozzle. I would hererernark that the-nozzle and the blade A are" so relatively arranged that when the scraping edge 7 of said. blade is incontact with the painted" surfaceto be scraped the- .frontedge 10 or forward endof the nozzle isspaced from said surface in the operative position of the blade shown in Fig. 1. The head D of the nozzle is widest at its front edge 10 or forward end and gradually reduced in width toward its rear end. Said nozzle has a tubular neck 03 which projects rearwardly from the rear end of the head D and is arranged centrally widthwise of said head. The neck (1 is in communication with the chamber 8 and is employed in conducting the fluid fuel, such, for instance, as gas or gasolene, to said chamber. Said neck is shown screw-threaded internally of its outer end,as at 13, and adapted to be connected in any approved manner to' the body (not shown) of a hand-torch or attached to a flexible tube (no-t shown) leading from a pipe for supplying fluid fuel.

By the arrangement of the parts hereinbefore described it will be observed that the plate B extends widthwise of the head D and has its side edges 14 (see Fig. 2) converging rearwardly. The paint-burning nozzle and the plate B are parallel, and said plate is provided at the rear end of the head D with a rearwardly projecting arm 6 arranged longitudinally of and engaging the neck (1 of the nozzle. Said neck is provided with any suitable number of apertures 03 which form the air-inlets of the nozzle. Said neck is preferably substantially circular in cross-section, and the arm 6 is curved transversely to conform to said neck. The arm 6 is provided centrally between its side edges with a slot 15 extending longitudinally of the arm and hastwo anges 16 arranged at opposite sides respectively of and extending longitudinally of said slot and overlapping opposite side walls respectively of a recess 17 formed in and extending longitudinally of the neck d of the nozzle. It will be observed therefore that the paintburning nozzle is adjustable longitudinally of the arm (Z,or, in other words, the blade A is adjustable longitudinally of the nozzle,and that the projection of the flanges 16 of the neck 03 of said nozzle and the side walls of the recess 17 prevent displacement of said arm circumferentially of said neck without interfering with the adjustability of said arm endwise of said neck. As shown in Fig. 2, the flanges 16 are spaced at their ends from the ends of the recess 17, and said recess therefore is long enough to accommodate any desired relative readjustment of the nozzle and the connected blade A. By the construction hereinbefore described it will be observed that the plate B and its arm I) constitute a nozzle-engaging member arranged exteriorly of the nozzle and extending opposite said recess; that said nozzleengaging member is connected to the blade A; that said blade is arranged to scrape the burned paint from a painted surface operated on by the flames issuing from the orifices 12 of the nozzle during the operaare secured in the desired relative adjustment by a suitably applied bolt E and nut G. As shown in Figs. 3 and 4 the shank of the bolt E extends through the nozzle-neck d' and through the slot 15 and has its free end arranged adjacent said slot, and the nut G- is screwed onto said shank and against the arm I) externally of said slot, and the bolt has a head e formed thereon at the opposite end of said shank and overlapping the exterior' of the aforesaid neck.
