SCRAPING DEVICE Filed June 16. 193a ATTO 27 BY RNEYS? I Patented May 25, 1937 Q ,UNITED STATES" PATENT OFFICE SCRAPING DEVICE Benjamin D. Kilcup, New York, N. Y.

Application June 16,

3 Claims.

This invention relates to improvements in scraping devices and has particular relation to scraping devices of the type used by painters in removing calcimine, paint and the like from walls and ceilings.

It is an object ofv the invention to provide improved means in the form of a receptacle to be used in association with a broad knife, or other type of scraping implement, to receive the scrapings and shavings falling from the knife when in use and prevent them from being deposited on the floor.

A further object is the provision of an improved receptacle which may be used with scraping knives, or broad knives of standard construction and of various sizes and shapes, and which is arranged and designed'so as to receive the scrapings coming therefrom and which does not interfere with the proper use of the knife.

With these and other objects in view reference should be had to the accompanying drawing in which- Fig. 1 is a side view partially in section of a scraping knife embodying my invention in association with a broad knife of conventional construction showing the device as being used in scraping a ceiling;

Fig. 2 is a sectional view similar to Fig. 1 showing the device being used in scraping a wall;

Fig. 3 is a front elevation of the device in association with a broad knife; I

Fig. 4 is a rear view of a portion of the device; and

Fig. 5 is a perspective view of the lower endof the device embodying my invention.

My device comprises a receptacle, indicated by the numeral II], which may be used in associa tion with the conventional type of scraping knives, such as the broad knife indicated by the numeral II which comprises a handle portion l2 and blade portion l4 having diverging side edges terminating in the broad scraping edge.

Thereceptacle preferably is provided with a slotted opening adjacent the bottom through which the blade of the scraping knife is inserted, and with a tapered upper portion having an opening therein through which the upper end of the knife blade projects. In the preferred form of my invention shown in the accompanying drawing, the receptacle consists of a bottom member l5 formed with a slot I6 extending transversely thereof and through which the blade of the knife is inserted, a pair of side members l'l each having a taperedor angularly disposed upper portion l8 terminating in'a relatively nar- 1936, Serial No. 85,467

row blunt portion l9, a rear wall 20 extending from the bottom to the top'of the side members and a front wall 2| extending from the bottom to the tapered portion of the side members as shown. A top member 22 connects the upper ends of the side members and the rear wall. It will thus be seen that the receptacle adjacent the tapered upper end thereof is provided with an opening 24 extending from the top of the front wall 2| to the top member 22 and through which the scraping edge of the knife blade projects and through which the scrapings or shavings are received in the receptacle. The bottom, top and side members and the front and rear walls of the receptacle are made of a suitable material, preferably metal, and may be made in one piece from a single blank of material or may be suitably secured together as by being soldered, welded, brazed or the like.

In using my device the blade |4 of a scraping knife is inserted through the slot H5 in the bottom of the receptacle and projected upwardly through the opening 24 formed in the front of the device adjacent the upper end thereof, and, accordingly, the slot I6 and the opening 24 are so positioned that the blade may extend at an angle, as shown most clearly in Figs. 1 and 2, and project outwardly through the opening a sufficient distance so that the knife may be used in scraping walls, ceilings or the like without interference from the receptacle. However; the end of the blade must be positioned relatively close to the opening 24 as shown so that the scrapings and shavings falling from the knife will be deposited in the receptacle.

To hold the knife in position after it has been inserted as shown and described, I provide means such as a rod 25 extending transversely of the receptacle adjacent the upper endof the front wall 2| as shown which engages the inner face of the blade I4 when the blade is inserted between the rod 25 and the upper end of the wall 2| as shown, thereby aiding to hold the blade in proper position with respect to the opening 24. I also provide clamping means in association with the bottom of the receptacle for releasably clamping the handle of the scraping knife and holding it firmly in position while in use. The clamping member is preferably a releasable type so that the knife may be inserted or removed from the device when desired. A very satisfactory form of clamping device is shown in the accompanying drawing and consists of a member formed of resilient or spring metal pivotally mounted in a bracket 26 secured to the bottom of the receptacle in front of the slot l6 formed therein. The clamping member is in the form of a wire strip extending through the bracket 26 and depending downwardly at both sides, the two sides 2'! being bent so as to extend beneath the slot I6, as shown, adjacent the central portion thereof, and then being bent forwardly adjacent the lower ends thereof, as shown at 29. The two sides 21 of the clamping member are spaced apart a sufficient distance so that they may be forced over the handle portion of the scraping knife, as shown in the drawing, and are sufficiently resilient to accommodate handles of various sizes and shapes.

For this purpose the lower ends 29 of the clamping member preferably are not connected together so that the side members may be readily spread apart to receive handles of various sizes.

In applying my receptacle to a Scraping knife, the knife is first inserted through the slot i6 and projected upwardly so that the upper end thereof extends between the rod 29 and the upper end of the front wall 2! outwardly through the opening 24. The resilient clamping member 2'! is then secured around the handle portion of the knife, as shown, thereby securely holding the knife in position in the device. It will be seen that the horizontal portions 28 of the clamping member are then disposed beneath the blade and prevent the knife from being accidentally dislodged. When the knife is then gripped by the handle and used in scraping walls or ceilings, the scrapings or shavings therefrom will drop downwardly through the opening 2 2 and be deposited inside the receptacle. In Fig. 1 the device is shown as being used in scraping a ceiling and it will be seen that the scrapings drop downwardly by gravity throughthe opening 2 In Fig. 2 the device is illustrated as being used to scrape a Wall and it will be seen that the shavings or scrapings fall downwardly along the top of the knife blade to the inside of the receptacle.

From the foregoing description it will be appreciated that I have provided an improved scraping device which may be used in association with scraping knives of various sizes and shapes and -which will collect scrapings or shavings falling therefrom and prevent them from being deposited on the floor. It should be understood, of course, that various modifications may be made in the herein described and illustrated embodiment of my invention without departing from my invention as set forth in the accompanying claims.

It will be noted that the receptacle I 0 not only serves to receive the scrapings or shavings from the broad knife but also, because of its relative position with respect to the end of the broad knife, serves as a guide and prevents the knife from digging too deeply into the surface of the material which is being scraped much in the manner of a, plane.

I claim:

1. A device for use with a scraping knife comprising a receptacle formed with a bottom member having a slot therein, side members tapering adjacent their upper ends, a rear wall extending the entire length of the side members and a front wall extending from the bottom to the tapered portion of the side members so that the front of the receptacle adjacent the upper end is provided with an open portion, the slot in the bottom and the open portion being so positioned that the knife may be extended through the slot so as to project outwardly through the open portion, and means adjacent said open portion for engaging the blade of the knife for guiding it and holding it in position, and a clamping member adjacent the slot in the bottom for engaging the handle of the knife.

2. A device for use with a scraping knife comprising a receptacle formed with a slot in the bottom thereof and tapering toward the top and having an opening adjacent the tapered portion, said slot and opening being positioned so that a scraping knife may be inserted through the slot and projected through the opening, said receptacle being provided with a transverse rod in the inside thereof spaced a short distance from the opening for guiding the blade of the knife and holding it in position and with a clamping member for engaging the handle of the knife and releasably holding it in position.

3. A device for use with a scraping knife comprising a receptacle formed with a slot in the bottom thereof and tapering toward the top and having an opening adjacent the tapered portion, said slot and opening being positioned so that a scraping knife may be inserted through the slot and projected through the opening, said receptacle being provided with a transverse rod in the inside thereof spaced a short distance from the opening for guiding the blade of the knife and holding it in position and with a clamping member for engaging the handle of the knife and releasably holding it in position, said clamping member being formed of resilient spring metal and having pivotal mounting adjacent said slot.
