Application April 22 lash-se ming .157,459 4Claims.' (01.30::293)
This invention relates to a tool for cutting the edge of a carpet or some floor covering.
In the cutting of a carpet which has its marginal cut edge doubled under or tucked beneath it, considerable skill is required in theme of a sharp knife in following a straight line or any irregularities which may occur in the wall-against whichthe carpet is to engage.
1 One of the objects of this invention is to provide a tool which will simplify the operation of cutting of the carpet.
Another object of this invention is to provide a tool which will follow irregularities of the wall.
' Another object of-this invention is to provide a I tool which may be adjusted for the accommodation of a carpet of different thicknesses.
Another object of this invention is to provide a cutting tool which may be arranged for use by either the right-hand or left-hand.
Another object of this invention is the provision of a tool which will be so constructed that it is rigid and will withstand the strains which are exerted in cutting a heavy carpet.
With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claims.
In the accompanying drawings:
Figure 1 is a perspective view showing the floor, wall, carpet, and the cutting tool as operating upon the carpet;
Figure 2 is an edge view of the tool with the carpet removed; and
Figure 3 is a sectional view on line 33 of Figure 2.
In proceeding with this invention I have provided a rigid body member which has a plate with an edge to engage the floor to he slid along the floor, while the rear surface of the plate may engage and be guided by the vertical wall which extends upwardly from the floor. Upon this body there is a cutter carrier which has a bracketlike formation upon which the cutter may be mounted for either right-hand or left-hand operation, the cutter being pivoted on this bracket and urged in one direction by threaded means. The carrier a so permits of adjustment for the accommodation of various thicknesses of carpet. The construction is essentially rugged and, therefore, rigid and will withstand substantial strains.
With reference to the drawings, l0 designates the floor of a room which is to be carpeted and H a wall extending perpendicular to the floor, while there is a baseboard I2 extending along the lower edge of the wall also perpendicular to the'floor H3. The "carpet is designated M. It is usual that the carpet be laid by first securing to thefioor ID a plywood strip l5 with a plurality of spurs standing up therefrom so as toleave a space I! from theb'aseboard [2 which is of a dimension depending upon the thickness of the carpet but is such asto accommodate the carpet edge doubled back or tucked beneath itself. The carpet is thus trimmed so that the edge when tucked beneath itself will just fit into this space I! and .thus when the carpet ispressed upon the prongs 16, it will-remain in place with its-doublededge'against the baseboard i2.
- Thetool'which is used. for cutting this carpet M is designated generally l8 and comprises a body member I9 which has a solid block-like portion 20 with an anvil plate 2| either formed as an integral piece therewith or, as shown in the drawing, secured thereto such as by screws 22 so as to be rigid therewith. The block 20 is provided with a pair of grooves 23 in its front face extending vertically and in a plane substantially parallel with the anvil guide plate I9.
A carrier 25 comprises a plate 26 with ribs 21 secured thereto by screws 28 in a location so that these ribs 21 will enter the grooves 23' and Qause the carrier to be guided in a vertical movement parallel to the plate 2|. The carrier has a slot 29' through which extends a screw 29 threaded into block 20 to hold the carrier in desired position. A bracket 30 extends forwardly from this carrier 25 at the lower edge of the plate 26 and is provided with a threaded recess 3! in its under surface. This threaded recess receives a screw 32 having a head 33 the shank of which pivotally mounts a blade holder 34, which blade holder is of an elongated form having a handle portion 35 at its outer end, while it is provided with a pair of jaws 33 at its inner end for gripping a blade 31. This elongated blade holder may be mounted either on the angle shown in Figure 3 forlefthand operation or the holder may be turned over with the screw 32 inserted through from the other side of the holder, thus disposing it at an angle degrees from that which it is shown for righthand operation. The junction of the edges of this bracket 30 are cut off as at 38 at 45 degrees to the edges and are recessed as at 39 so as to receive an arm 40 which is held in position in the recess 39 by a headed screw 4|. The upper end of this arm is turned over to provide a lip 42 to extend over the bracket and engage the surface thereof. When this arm 40 is mounted for lefthand operation, as shown in the drawings, there will be a screw 43 extending through the lower 3 part of the arm 40 to engage the tool holder 34, as shown in Figure 3, to urge it about its pivot until it is at the right position with reference to the anvil plate 2|. It will be understood that this arm 40 may be shifted into the other beveled corner 38 for right-hand operation therefrom as desired.
In use, the carpet is out so as t leave sufilcient stock from the edge of the pin board I5 to be tucked beneath itself and just fit into the space I! between the pin board and the baseboard and depending upon the thickness of the carpet will be the position of the out. When the location of the out is determined, the carriage will be adjusted so that the cut will be made at the proper location and then by pulling the carpet tight and feeding between the knife and the body portion 20, the tool may be guided along the floor surface with its rear face against the wall and a cut will be made at the right location, the arrangement being shown so that the tool is more convenient for a left-hand operation and advanced away from the viewer. However, it will be readily apparent that the blade holder may be reversed as to its inclination for a right-hand operation.
I claim:
1. A carpet cutting tool comprising a body member having an anvil plate with a lower edge 'for engaging the floor and a rear face for engaging a wall, a support mounted on said plate at a location spaced from said lower edge and extending at right angles thereto, a cutter carrier spaced from said plate and mounted on said support for relative movement in a plane generally parallel to said plate toward and from said 4 lower edge, a blade holder secured to said carrier, and a blade in said holder positioned with its cutting edge toward and in close proximity to said anvil plate for cutting the turned-up edge of a carpet disposed between the blade and anvil plate.
2. A tool as in claim 1 wherein relative movement between said support and cutter carrier is slidable with tongue and groove guiding means.
3. A tool as in claim 1 wherein said blade holder is pivoted on said carrier and adjustable stop means for limiting the pivotal movement of said blade holder.
4. A tool as in claim 1 wherein said cutter carrier has a bracket extending away from said plate and said blade holder is pivoted on said bracket.
