Application June 30, 1947, Serial No. 758,125
2 Claims. 1 This invention relates to tile cutting devices. It is an object of the present invention to provide a tile cutting device which is adapted to support a piece of tile which is either square with Fig. 2 is an end elevational view of the tile cutting device.
Fig. 3 is a top plan View of the device.
Fig. 4 is a transverse cross sectional view taken the cutter or at an angle, and wherein there is on the line 4-4 of Fig. 1, looking downwardly in a beam on which the cutter rides and over which it is slid to effect a cut on the top of the tile.
It is another object of the present invention to provide with a tile cutting device a breaking arrangement which will engage with th top of the tile in a flush manner after the same has been traversed by the cutter to break the tile in two parts.
Other objects of the present invention are to provide a tile cutting device which is ofsimpleconstruction, light in weight and easy to transport, inexpensive to manufacture and efficient in operation.
In according to the invention, there is provided a raised or box-like base on which there is supported the tile to be cut and on which there is pivotally mounted a beam which carries the cutting tool adapted to slide over the top of the tile as the beam is brought down over the tile. Gauging means are provided for properly locating the tile underneath the cutter and this gauging means includes a transversely adjustable member set into the top of the base and on which is a protractor which is used when it is desired to cut the tile at an angle. Once the gauge means have been set, the tile can be retained and an accurate cut made on the same.
Associated with the device is an upwardly extending adjustable member near the hinge connection ofthe beam on which the tile is disposed and below a member on the beam which is pivotally connected thereto so as to adjust itself to the top of the tile and lie flush thereon as pressure is brought down to break the tile over the member. The rear ends of the beams will rest upon a stop when in place and this stop will prevent the cutter supporting member from leaving the beam as it is drawn rearwardly to cut the tile. The base can be fastened to any work bench or supporting surface.
For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.
In the accompanying drawing forming a material part of this disclosure:
Fig. 1 is a perspective view of the tile cutting device embodying the features of the present invention.
the direction of the arrows thereof.
Fig. 5 is an enlarged perspective view of the adjustable holder for the tile removed from the base.
Fig. 6 is a cross sectional view taken on line 5-4; of Fig. 3.
Fig. '7 is a transverse cross sectional view taken on line 1--? of Fig. 3, looking upon the end of the cutter element supporting member.
Fig. 8 is a bottom plan view of the cutting element and its supporting member removed from the beam.
Fig. 9 is a longitudinal cross sectional view taken on line 99 of Fig. 3, looking on the roller bearing side.
The tile cutter, according to the present invention, includes'a box-like base l5 having end projections [6 through which screws can be extended for fixing the same t a work bench or supporting surface. Extending upwardly from the rear end of the top surface of the base 95 there i a sup port I! to which a beam I8, extending longitudinally over th top of the base I5, is pivoted by a pivot bolt [9. This support l1 has upwardly extending projections 2! to retain the beam it against lateral displacement and in a rigid manner when the beam is lowered onto a tile supported on the top of the base l5. In th top of the base, there is a transverse opening 22 through which there is extended an elongated gauge bar 23 having indicating grooves 24 in its top face spaced one-half inch from each other. This gauge bar 23 is retained in its adjusted position by a bolt 25 extending longitudinally through the interior of the base l5 and through the rear end 1 of the same to receive a wing tightening nut 26.
The gauge bar 23 is formed with an elongated slot 21 (Fig. 5) through which the bolt 25 is extended. By loosening the bolt 25, the gauge bar 23 can be adjusted to the proper setting. On this gauge bar 23 and at one side of the base l5 there is an upwardly extending squar 28 for receiving the corner of the tile. This square has a protractor portion 29 with an arcute slot 3| therein. Through this slot, there is extended a tightening bolt 32. The square 28 can, accordingly, be adjusted to any angle so that the tile engaging therewith can be cut diagonally at the desire angle.
At the rear end of the base I5 is an adjustable stop 33 with a knurled locking nut. This adjustable stop will prevent the cutter from hitting the base i5 and marring the cutter when scoring and breaking the tile. To prevent the carriage 39, to be hereinafter described, from leaving the beam l8 when the beam I8 is raised above the stop 33, there is a stop 35 on the rear end of the beam. This stop 35 is retained in place by a bolt 36.
A carriage 34 made of two parts is engaged about the beam [8, and rests on two roller bearings 39, see Figs. 7 and 9, for a sliding movement thereover. The two parts will be held together by screws 31. The two roller bearings 49 prevent wearing out-of the beam l8 and the carriage 34, so as to perform a true cutting at all times, and provide for smooth sliding movement of the carriage 34 over the beam l8. In one end of the carriage there is a built-in cutting element support 33 for a cutting element or wheel 39. As the cutting wheel is dragged over the glazed tile surface, the surface will be penetrated and a line formed thereon.
Thereafter, the tile piece will be lifted and dis posed within the breaking device wherein it will be divided into two parts. This breaking device comprises an adjustablesupport ll disposed near the upright support H and beneath the beam I8. This support includes a locking nut 82 to retain a top anvil G3 in its elevated or adjusted position. On the beam it! there is a transversely extending member 69 having separated upwardly extending portions 45 by which the same is pivoted by means of a pin 46 to the beam i8. Within the bottom surface of the member Q4, there is a longitudinally extending groove '38 adapted to be aligned with the anvil es and of generally the same curvature as the anvil. Accordingly,
when the beam is brought down over the ti1e,-
which may be resting on the anvil 43, great pressure will be applied to the top surface of the tile so as to apply pressure to opposite sides of the line of the out on the tile surface. When sufficient pressure has been applied, the tile will snap into two parts and a clean break will have been effected.
While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed, and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:
1. In a tile cutting device having a hollow boxlike base with a fiat top upon which a tile to be out can be rested and a cutter movable longitudinally of the base to score a tile resting on the top face of the base, means for properly positioning the tile on the top face of the base with relation to the cutter, comprising an elongated gauge bar, the base being formed with a transverse slot opening through its top face and in 4. i which the bar is slidably disposed for movement transversely of the base, said bar being of a thickness corresponding to the depth of said slot so that the top face of said bar is flush with the top face of the base, a square mounted on one end of said bar to one side of the base to engage one corner of the tile resting on the top face of the base, means for securing said bar in various transverse adjusted positions relative to the base, and a plurality of indicating grooves formed in the top face of said bar and spaced one-half inch from each other, so constructed and arranged that the grooves are clearly exposed along the entire length of said bar to be plainly visible for alignment with an edge of the top face of the base and/or the edge of the tile to be cut.
