1 Claims. (Cl. 164-73) This invention relates to newand useful improvements in edging tools.

One object of the invention is to provide an improved edging tool for marking or scribing linoleum, or other similar floor covering, so that when the linoleum is out along said marking it will fit snugly-along the wallet the room. 7 Another objectof the invention is to provide an improved edging'tool which includes a [curved ing, it will snugly fitfagainst the wall of the room.

' An important object of the invention is to providean improved edging tool for cutting linoleum and the like, in such a way that said linoleum will fit snugly against the wall of the'room wherein it is laid.

A further object of the invention is to provide an improved edging tool for marking or scribing linoleum or the like, which has adjustable guide means for engaging the wallet the room to guide said tool during the marking operation.

'Still another object of the invention is to provide an improved edging tool for marking or scribing linoleum, or other similar materialwhich includes a slot which receives the linoleum to be cut, the slot being adjustable in width so as to receive linoleum, of various thicknesses.

A construction designed to carryout the in: vention will be hereinafter described, together with other features of the invention.

The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawing, in which an example of the invention is shown, and wherein: n v

Figure lis' a side elevation of an edging tool,

constructed in accordance with the invention.

Figure 2 is an enlarged sectional view, showing a cutting disk substituted for the stylus.

Figure 3 is a transverse sectional view, taken on line 3-3 of Figure 2.

In the drawing, the numeral Ill designates a frame member which forms the main supporting element of the tool. The frame includes a vertical side H and a horizontal base l2. The rear of the frame is formed of an arc l3 which is preferably made integral with and curves downwardly from the verticalside II. A roller 14 is mounted in the base [2 and serves to support the ,as to ride in the corner formed by the intersecrear of the frame. A suitable guide roller I5 is carriedby a horizontal bar i6 which is mounted at the forward end of the base; The bar I 6 is provided with an elongated slot Iii. Bolts I! pass through the slot and through the base 12 and re- 5 ceive thumb nuts l8 on their upper ends. It is obvious that by loosening the nuts Hi, the bar l6 and the roller it carried thereby may be adjusted with relation to'the frame. It ispointed out that the entire frame is carried by the rollers l4 and, 10 [5. A suitable handle 58 is provided in the frame 10.

A curved slot 19 extends from the lower end of the rear side of the frame; and is curved upwardly terminating at the forward endof the I frame near the upper'e'nd thereof. The bottom of theslot is formed of a curved swinging member 20 which' is pivoted at its lower end at 2|. An adjusting'screw 2'2 threaded in a boss 23 on the frame has its upper end journaled in the swing- 20 mg member 2% whereby rotation of the screw will swing said member. It is obvious that by adjusting the screw .22 thewidth of the slot may be controlled. 7

A stylus 24 is mountedin the frame and has its 25 pointed end extending into the slot I9. The stylus is adjustably 'mounted in a bearing 25 which is slidable through a boss 28 in the frame.

The bearing 25 has a rod 26 integral therewith and the outer end of said rod extends through a 30' boss 21 on the are iii of the frame. A spring 28. surrounds the rod and it is confined between the boss 2'! and an adjusting nut 29 which is threaded on the rod 26. It'is obvious that the spring serves to hold the stylus well within'the slot, the ten-; sionof said spring being varied by the adjusting nut 29.

In laying linoleumA or other fioor covering its has been found that itis difficult to cut the linoleum A along a line so that said linoleum 40 will fit snugly in the corner formed bythe intersection of the floor with the wall. By providing the above described tool such correct marking is readily obtained. In using the tool the linoleum A is cut to within an inch or two of the point 5 where it must actually be out to fit the fioorperfectly. This cut end is then inserted into the slot curving upwardlytherein as shown in Figure 1. The guide roller i5 is then positioned so tion of the floor and wall. When the tool is in this position the distance from the lower rear end B of the frame it) to the point C where the stylus engages the linoleum within the-slot I9 is the same as the distance from the point B to the corner D formed by the intersection of the wall and the floor. Thus by moving the tool along the wall keeping the guide roller at the point D the stylus will mark the linoleu 1 along the exact point where it is to be cut. If it is desired to loosely fit the linoleum the guide roller I 5 may be moved forwardly of the frame by loosening the nuts [8 and moving the bar l6 forwardly. If the intersection between the wall and the floor is curved, as it is in some cases and as shown in dotted lines in Figure l, the guide roller I5 may be retracted at the dotted line shown in Figure l, and the tool may be guided by a small roller which is carried by an'adjustable bracket 3| which is threaded in a boss 32 in the lower forward end of the frame. The roller 36 engages the Wall of the room above the corner D, and it is clear that said roller will serve as a suit able guide.

From the above it is obvious that the stylus will mark'the linoleum on the line where it is to be cut but it is possible to substitute a cutting disk 33 for said stylus as shown in Figure 2. Thus when the tool is moved along the wall the disk would cut the linoleum along the desired or correct line. This would obviate the necessity of cutting the linoleum by hand after it had been marked.

The advantages of the tool are obvious. It is only necessary to insert the linoleum in the slot l9 and draw the tool along the wall of the room. By adjusting the tension of the spring 28 the depth of the marking is readily controlled. As the tension on the spring becomes Weaker theadjusting nut 29 may be tightened. The adjusting of the guide roller [5 provides for variation of the line of marking and the adjustability of the width of the slot l9 provides for accommodating linoleum of various thicknesses. The tool is :simple and compact in construction and manu facturing costs are held to a minimum. The stylus 24 is the only part which receives any amount of wear and this is readily replaced and adjusted.
