COMBINATION TORCH HOLDER AND PAINT SCRAPER Filed June 9, 1952 INVENTOR EVERETT 1.. MARESCA.

ATTOR NEY Patented Jan. 5, 1954 UNITED STATES PATENT OFFICE COMBINATION TORCH HOLDER AND PAINT SCRAPER Everett J. Maresca, Baldwin, N. Y. Application June 9, 1952, Serial No. 292,461 9 Claims. (01. 158-13.6)

This invention relates to a torch holder and paint scraper, particularly to a combination device of the above category adapted for use with the nozzle of a gasburner.

In removing paint from a surface, such as the hull of a boat, the common practice has been to separately burn and scrape off the paint, the operator generally holding a burner in one hand andthe scraping tool in the other, and directing them simultaneously. Because of the obvious difficulty of coordinating both hands in proper relation to the surface being worked on, inadvertent scorching of the surface often takes place,

resulting in damaged and unsightly areas. Although some attempts have been made to employ tools for the purposeof combining the two operations, it has been found that they are either too cumbersome for effectively controlled and uniform action, or insufficiently adjustable for different conditions, such as different paints, surfaces and fuels, whereby it is often necessary to replace the entire unit to suit each condition. With such conventional devices, it is also generally necessary" to employ an entirely new unit when the burner or scraper has outworn its usefulness.

It-is within the contemplation of my invention to provide a convenient implement which can serve both as a holder for a torch and as a paint scraper, the device being adapted to removably receive different burner elements of variouscommercial forms and sizes. And in this aspect of my invention it is a further object to enable replacements of worn out burners. and blades to be readily made. It is a further object of my invention to provide for a variable relation between the scraper blade and a burner operatively supported by the holder, the relationship being adjustably effected by a simple manual adjustment. And in this aspect 'of my invention it is a further object to enable a ready change of the distance between the scraper edge and the flame tip to be effected, in accordance with the requirements of particular flame intensity and the physical condition of'the surface to be scraped.

It is a further object of my invention to provide, in a device of this category, a combination of hand gripping portions for easy and efficient two-hand operation and for such effective control of the burning and scraping operation as to reduce to a minimum the time required therefor, and at the same time to eliminate the danger of inadvertent scorching of the wood.

It is within my contemplation to provide a light portable and readily fabricated device,

2 operatively employable with conventional gas and liquid burners or jets connected to a source of fuel or steam supply.

Other objects, features and advantages will appear from the drawings and the description hereinafter given.

Referring to the drawings:

Figure 1 is a side elevational view of a preferred form of my invention connected to a fuel supply hose, and showing the flame and scraper blade operatively being applied to a painted surface.

Figure 2 is a top view of the hand gripping portion of the burner holder of Fig. 1.

Figure 3 is a fragmentary elevation of the device of Fig. 1, shown partly in section, illustrating an adjusted position of the blade with respect to the flame tip.

Figure 4 is an end view of the front portion of the device shown in Fig. 1, looking in the direction of lines 4-4, a fragment of the blade and base being shown in section, the burner being removed.

Figure 5 is a fragmentary bottom view of Fig. 4.

Figure 6 is a top view of Fig. 4 also showing the burner member in place, it being a section of Fig. 1 taken substantially along line 66.

Figure 7 is a perspective view of the scraper blade shown in the previous figures.

Figure 8 is an enlarged fragmentary section of the lower portion of Fig. 4.

Figure 9 is an end view member, substantially like but without the blade and bushing in place, and I Figure 10 is a section of Fig. 9 taken along line I9l 0 thereof.

In the preferred form of my invention illusr he nozzle clamp II is shown consisting of two separable halves I2 and I3, each half containing walls and I5 which combinatively form an internal conical wall I6 tapering inwardly from the rear end Ila to the forward end IIb of the clamp, the arrangement being such as to accommodate a conical burner nozzle I8. Components I2 and I3 have oppositely extending flanges I9I 9 and 20-20 in facing relation and adapted to be secured together by screws 2! extending through countersunk holes 22 in flanges l9 and in threaded engagement with the tapped holes 23 in flanges 20. The top of the clamp II contains the pad 24 upon which is positioned the base 25 of the burner holding that shown in Fig. 4, base, and showing a of the handle 26, the screw 21 extending through the hole 28 in base 25'and being in threaded engagement with the tapped hole 29 extending downwardly fromthe upper surface of pad 24 .01: blade 449 beingr pnliedito-thersai thelhandle m are sim. 1taneous1r,--h dnthereris through the conical surface i6 of the central passageway 30.

The bottom of clamp l I contains the apertured fiat bar 3| disposed between the bifurcated 40 comprising a thickened rear portiprrAl and a forwardly disposed relativelvthirr plate 42, the front wall 43 of said thickened portionfl serving' as an abutment for the blade member Ahresting against the underside 450i plate 42. It Willbe' obs ved that the said un ersi fl fiq i ms v 2o ribs 45; these being paraller'and'extending-long} tudinally along --pl te 42'."
