1 Claim. (Cl. 15157) This invention relates to an improved scraping and calking tool for use when scraping and calking the decks of a boat, it being one object of the invention to provide a tool including a handle and 2 while the tool is in use. The forward end of the handle is formed with a longitudinally extending socket 3 to receive the shank of the tool carried by the handle, this socket being rectangular in detachable tools which may be selectively apcross section so that when the shank or the tool plied to the handle and firmly held so that they is fitted into the socket it may not turn out of will not slip out of connection with the handle proper relation to the handle.

or out of proper relation to the handle while in The scraper is shown in perspective in Fig. 4, use. and, referring to this figure, it will be seen that Another object of the invention is to provide a this scraper is formed from a bar of carbon steel tool of such construction that it may be used while of appropriate width and thickness. The bar is standing or leaning over instead of it being necbent intermediate its length to form a blade 4 essary to kneel upon the deck. which is connected with the rear portion 5 of the 7 Another object of the invention is to provide a tool by a curved portion 6 projecting upwardly scraping and calking tool of such construction from the front end of the rear portion 5. This that a hose leading from a source of compressed curved portion imparts added weight to the air may be mounted along the handle and shank scraper so that the sharpened lower edge I of the of the tool in such position that an air blast blade 4 will readily cut the surfaces of deck may be discharged forwardly to clear the deck or planks and also readily cut hardened tar protrudcalking slot of dirt during use of the tool. ing from a deck seam. The lower edge face 8 of Another object of the invention is to provide the blade is ground diagonally to form the sharpa tool wherein the scraper is of such formation ened edge I and, from an inspection of Fig. 1, it that it has added weight and also sufiicient rewill be seen that when the scraper is in use, the sillency to prevent it from being bent or broken edge face 8 is parallel to and rests flat upon the when in use. deck planks. It should also be noted that the Another object of the invention is to so form angle at which the blade extends is such that the the calking tool that it may clear the bottom of a sharpened edge has a planing action when scrapcalking crack or groove between deck boards ing a deck or removing protruding tar from a deck and also out side walls of the crack or groove and seam. Since the upper end of the blade merges undercut the same so that tar used as a calking into the curved portion 6, the curved portion will compound will be held in the groove. serve as a resilient member for preventing the Another object of the invention is to provide a blade from being bent out of the diagonal positool which is of simple construction, easy to option shown in Fig. 1. erate, and capable of being manufactured at The rear end portion of the bar or strip from small cost. which the scraper is formed is reduced in width to In the accompanying drawings: form a shank 9 which is of such width and thick- Fig. 1 is a side elevation of the tool showing the ness that it fits snugly into the socket 5 of the scraper mounted at the front end of the handle. handle, as shown in Fig. 3, and this, shank is Fig. 2 is a view on the line 2-2 of Fig. 1. formed with a number of transversely extending Fig. 3 is a view looking down on Fig. 1. openings 10 which register with openings II so Fi 4 is a perspective view of the scraper. that bolts l2 may be passed through the handle F g- 5 is a Vi w Showing the calking tool mountand shank to firmly but removably secure the ed at the front end of the handle, the forward scraper to the fro t end of the handle w portion the Pandle W 1n sectlon; the bolts are removed, the scraper may be with,-

This improved scraping and calking tool has a thDuring usle of the scrapel ll? is desirable to have handle I which is of such length and thickness e dec Geared of scripmgs and other dirt that it may be conveniently held in a persons Therefore havmg a nozzle may be hand and deck boards scraped or Gaming grooves extended longitudinally of the handle and mountcleared and undercut While standing and leaned under the handle and the rear portion of the ing forwardly somewhat. At its rear end, the scraper y cla p 5 and hich a e a lied handle is formed with an enlargement 2 so that to e handle d pe and engage about t e the handle may not slip out of a persons hands hose and its nozzle. The nozzle will thus be supported under the rear portion 5 of the scraper in such position that air discharged from the nozzle will strike the blade 4 and so'spread that it will clear the deck of shavings and other dirt.

In Figs. 5, 6 and 7, a calking tool is applied to the handle. This tool I! is formed from a bar or strip of carbon steel of suitable width and thickness. The bar is bent in spaced relation to its front end to form a blade I8 which extends downwardly from the body IQ of the tool and is curved longitudinally, as shown in Fig. 5. The lower end of the blade is ground to form a beveled edge face 2| having a cutting edge 2| along its front, and side faces of the blade are sharpened along their front edges 22. Since the blade is sharpened across its lower end and along its side edges it may be disposed within a calking groove 23 of a deck 24. Since the blade I8 is sharpened along its lower edge, the bottom of a calking groove may be cleared and deepened if necessary, and since the blade is sharpened along its side edges, the sides of the calking groove may be smoothed and under cut so that when tar is poured into a groove and hardens, it will be firmly held in the groove. After the tar has hardened the portion protruding from the calking groove is removed with a scraper of the construction shown in Figs. 1 through 4, the blade of the scraper being appreciably greater in width than the calking groove.

This improved calking tool is applied to the handle I in lieu of the scraper and has its rear end formed with a shank of less width than the body of the calking tool and of such dimensions that it fits snugly into the socket 3 of the handle. Openings 26 are formed through the shank to receive securing bolts l2. Shavings and other dirt is removed from the calking groove by an air blast delivered from the nozzle ll of the air hose extending along the handle and held in place by clamps carried by the handle and the calking tool.

Having thus described the invention, what is claimed is:

An implement of the character described comprising a handle, a scraper formed from a metal bar of greater width than thickness and having its rear portion constituting a shank connected with the front end of the handle, said bar being bent intermediate its length to form a flat body and a blade extending downwardly at a rearward incline and formed with a cutting edge across its lower end, clamps carried by said handle and the said shank and extending downwardly therefrom, and a hose extending longitudinally of the handle and having a nozzle at its front end, the said hose and its nozzle passing through and supported by said clamps under the handle and the shank with the nozzle directed forwardly in position for discharging air against the rear face of the blade.
