8 Claims.

The invention relates to improvements in devices for scoring and breaking tile, glass, and like vitreous material.

The principal "object or the invention is to provide adevice of this nature whereby tile and the like may be accurately and properly scored and then cut or broken with great precision.

Another object of the invention is to provide a relatively light-weight and compact device designed so as to be readily portable and one which is simple to operate.

Still another object of the invention is to provide a scoring and cutting device which shall accommodate extremely large tiles as well as small ones and which is, furthermore, suitable for cutting the tile diagonally and in various other fashions, as may be desired.

In carrying out the invention, there is provided on a suitable elongated supporting base a pivoted arm which carries a cutter slide movable longitudinally thereon, the slide bearing a cutter or scoring element whereby materiallocated on the surface of the base may be scored. The arm is limited in its movement toward the base by contact ofits free end with a buffer removably secured in the base at the end opposite the pivoted end of the said arm. Gaugemeans are arrangedin and for adjustment transversely of the base to properly guide and hold a tile or the like for the scoring operation. To break a tile, particularly of the thinner types, provision is made for a breaker element which is fixed to the pivoted end of the arm for cooperation with an anvil mounted in the base for adjustment vertically toward and away from said breaker to accommodate the thickness of the tile to be broken, a tile being intended to be located therebetween and pressure exerted on the tile by pressing down on the said arm.

Thenature of the invention, however, will best be understood when described in connection with the accompanying drawing, in which:

Fig. 1 is a plan view of the novel scoring and breaking device, and Fig. 2 is a side elevation thereof.

Fig. 3 is an elevation of the operating end of 4is an elevation of the opthe feet or lugs I2 through which the member may be rested upon or afiixed to a surface of a suitable support (not shown). At one end of the base there is provided an upstanding bifurcated bracket I3 to which is pivoted, as by means of an adjustable bolt, one end of an arm Id. The opposite end of this arm rests normally upon a butter l5 removably attached to the opposite end of the base, as by being screwed therein.

Mounted on the said arm to slide along the same is a carriage or slider member I6 having a downwardly extending bifurcated arm I6 carrying a scoring element or die such as the wheel Il. This may be removably held therein by screw I8, on the shank of which itrotates, so that when a cutter becomes worn, it may readily be replaced. In order to prevent theslider l6 normally from slipping ofithe free end of the arm, there is screwed into the latter a cap'member I9 which may be removed when it is desired to disassemble the device or remove the carriage.

At its pivoted end, the arm I4 has fixed thereto a breaker element 20 of any well-known design and having a longitudinal and shallow groove 20 along its median line. The breaker is arranged for cooperation with an anvil or breaker button 2| in the nature of a headed screw which is screwed into the surface III of the base and is adjustable vertically thereof toward and away from the breaker element 20 to accommodate difierent thicknesses of tile. A set screw 22 directed from the side wall ll of the base may be provided to fix the anvil member in its adjusted position.

To'locate properly a tile 25 or the like for cutting, one or more gauge means are provided for adjustment transversely of the base. For example, the surface ID of the base may be provided near its bulier end with a transverse groove 26 and is adapted to receive a bar 21 of a straight edge, provision being made for fixing the location of the straight edge as through a set screw 28 extending inwardly from the front oi the base to engage the samel To, accommodate larger tile and to provide for cutting at various angles, a further gauging means may be provided as the rod 30 fitting through the base transversely thereof and oscillatable therein so that its finger or right-angle extension 3| may be elevated above the plane of the surface III" of the base, as indicated by the dotted line position, Fig. 2 of the drawing. When the desired adjustment has been secured, this" may be fixed by means of a set screw 32 passing into a lateral boss 33 from the base.

Further locations, particularly with respect to accommodating odd shapes and sizes of tile, may be secured by providing a series of sockets 35 and 36 in the supporting surface ID of the base l and into which pins 31 may be fitted in the required position, such pins being readily removable from the socket when no longer required.

In operating the device, the same may be rested upon a suitable table or bench or, if necessary, secured thereto through the lugs "l2; Thereupon the slider gauge or gauges are set for the desired cut and the tile placed on the table and positioned against the gauge.

pivoted end of the arm and for scoring is drawn along the arm and over the tile withthe scoring Wheel ll contacting the same to suitably score the tile surface. The tile may be placed between the breaker button or screw 2| and the breaker 2|] with the scored line of break registering with the groove in the under surface of the breaker, the screw 2| being adjusted so that the breaker is a slight distance above the surface of the tile. By'pressing'down on the arm, the tile will'break along the line of scoring. In the case of extremely large tiles, the breakage may be efiected by cracking the tile with a hammer, in well-known manner.

Numerous advantages are found in the use of the novel device over those heretofore proposed. For example, its light weight and compactness permits it to be carried in the usualtile layers tool kit together with the customary other tools.

The simplicity of the mechanical action makes possible ease of operation and'provides for accurate and rapid performancewithcle'an and neat cut requiring no finishing operation.

Aside from the cutter, the'reis only one point where wear might occur, this being'w'here the arm I4 is pivoted to the upstandingbracket l3. Any wear, however, is readily accommodated by taking up on the adjustable bolt onwhich the arm rocks.

In view of the length of the arm"! which controls the breaking device, great power is afforded, and it "is possible to break tile of a heavier gauge than has ever before been cut.

The provision of the buffer in'additionto minimizing shock and noise prevents the cutting element or wheel from touching any part of the tool and thereby preserving it from any damage from this source.

The tool, moreover, can be used by a mechanic ordinarily working in awkward positions such as in small shower stalls as it may be fastened to the working board; and can be used, also, by either rightor left-handed mechanics with equal ease simply by supplying a gauge with reversely directed stop.

A clear working base is obtained simply by inverting the bar which removes the gauge stop and leaves the base clear to insert tiles of large sizes or odd shapes.

When one or more cuts are to be made, the tile to be cut is held in the hand, placed against the gauge stop, scored, inserted in the breaker, and cut, the desired cut portion being retained in the hand.
