TILE CUTTING AND BREAKING MACHINE Filed July 16. 1930 2 Sheets-Sheet 2 'NVENTOR, 5/7/9051. 1'. Gmq/v/ r5- Patented Oct. 31, 1933 UNITED STATES PATENT) OFFICE} 9 Claims.

The primary object of my invention, is the provision of a device possessing a marked improvement in divers ways over the fewand highly unsatisfactory cutting tools employed in the tile 8 cutting art.

" It is the object of my device thus, to place into the hands of the tile setter, a practical portable tool that not only will cut the highly glazed tile slabs commonly used in kitchens, bathrooms,

and food establishments, etc., in any desired or required form, but will simultaneously therewith separate the cut in an absolutely clean and even break.

The most efficient tool in use in the arttoday does not accomplish this result, it merely scores the top of the slab, the workman then finding it necessary to hit the underside of the slab with any convenient means to aifect the break, the resultant separation in many instances being far from a clean job, parts adhering that must be chipped off and frequently the slab is thereby spoiled, resulting ina loss'which due to the number of pieces of slabs required for the average job, makes such spoilage a costly factor.

I In the use of my device, no such unnecessary loss is experienced; My improved device not only scores the slab from the top, but also breaks and separates the slab, the scoring and even break pressure asserted by the device assuring a clean and even cut that cannot be produced as readily and as satisfactory, without spoilage by any type of cutter or separator means presently employed.

Another object of my device is the provision I of a cutting die that permits and enables the ways which will hereinafter be described, and

therefore I wish to claim all of these features herein.

I attain these objects by the device illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of my invention; Figure 2 is a top or plan view of Fig. 1; Figure 3 is an end elevation of Fig. 2 Figure 4 is a top 5 view of the table comprising the bedplate thereof Figure 5 isa sectional view taken on the line (c1. res-as) 5-5 of Fig. 2; Figure 6 is a sectional viewthroug'h l the table showing a tile of bull nosevariety positioned for scoring, the scoring wheel being positioned for starting the cut; Figure 7 is a fragmentary view showing the operating lever in position for breaking the tile; Figure 8 is a plan View of the table with the gauge for aligning the tile in position for scoring andbreaking} and Figures 9 and 10 are plan views-respectively of the table with my angle cutting gauge in position for cutting tile at varied angles. Similar reference characters indicate like parts throughout the several views, the reference character 1 thus indicating the base of my device, 2 is the table, said table being movably positioned on said base, and interchangeably posi- 1 tioned with the cuttingand scoring means. In

practice I have found it expedient to reverse the same from the position shown in the drawings,

so that the scoring of moulded tile may the more readily be accomplished, reversing the table and cutter means providing increased clearance for the cutting device than that shown, 3 are guide columns, 1 yokes for carrying breaker bars 10, said breaker bars are lined on their underside 0 with a rubber liner or shoe, the purpose thereof being toprevent the surface area. of the bars from coming into direct contact with and marring the glazed surface area of the tile slab,- and to assure a cushioning effect between the'two, 35 this being a desirable feature as tile slabs do not always run true to form, the said yokes 4 being held in elevated position by springs] 5. Guide and pressure bars 6 are secured to the guidecok umns 3 by pins or bolts 7-whicl1 pass through holes 8 in the guide bars 6 and holes 9 in the columns 3, it being possible to move said guide bars from the lower and upper holes 9 when additional space between the table and breaker bars is. required. Pockets 11 in the yokes 4 permit of 5 positioning the breaker bars 10 for handling either narrow or wide tile.

A tongue 12 is formed alongthe center of the table 2, and a slot 14 in said table provides a recess forthe ends of tile of the bull nose type, as is very clearly indicated in Fig. 6. A pocket 15 I in table 2 serves to give clearance for the scoring knife or diamond 23, and on the edge of the table, a scale 16 readily provides an adjusting means for correctly setting any gauge it is desired to use.

A lever 17 and engaging handle means 18 in cooperation with a bell crank 19 carries trunnions 20' on which rollers 21 revolve. Secured to lever 17 are pivots 22 as will be noted Fig. 7 110 wherein the lever is indicated in position for breaking the already scored tile. The pivot 22 being against the bar 6, moving the lever 17 to the right forces the rollers 21 down against the breaker bars 10, said bars forcing the tile against the breaker knife 13, this sequence of operation causing the tile slab to separate in a straight and uniform cut or break.

On the forward side of the lever 1'1 a diamond or cutter 23 in a cutter bar 24 is secured to said lever by means of screws 25. Secured to the scale 16 at right angles is a gauge 26, said gauge being juxtapositioned parallel to the breaker knife 13 by a grooved base 2'7 which fits over the tongue 12 of the table 2, said gauge 26 being used for making straight cuts only. Where it is necessary to make angular cuts, I mount a secondary gauge 28 upon the gauge 26 by a clevis 35, the tongue 29 of the gauge 26 passing into the bifurcated end 30 of the clevis 35 and is movably held in position by a pin or bolt 31, said gauge 28 being provided with a groove or cut out portion 36 and incorporating a triangular shaped cut-away portion 3'7 for engagement of the tile slab.

As shown in Fig. 10, gauge 28 is in position for cutting tile slabs at an angle of 45 degrees, a bolt 32 secures a slotted finger 33 to the gauge 28 and the finger 33 may be moved inwardly or outwardly to secure the gauge 28 in any desired posi tion for holding the tile slab at any predetermined cutting angle.

My improved device is readily adaptable to the cutting at any conceivable angle of every known type of tile slab and in thickness from to 1", inclusive of embossed tile and moulded trim.

It cuts and breaks the tile slab without chipping and uneven breaks, is quickly and readily manipulated by the setter, and being portable and as light in weight as structural details permit, readily carried about from job to job.

As a practical article of manufacture, the device is readily produced from materials obtainable in the open market.

It is of simple construction, of few parts, can hardly be held subject to getting out of order, and requires no expert knowledge to use.

I am aware that slight modifications may from time to time be madein the details of construction illustrated without departing, however, from the scope of the present disclosure, and as defined in the claims which are appended hereto. Hence, I do not limit my present invention to the exact description of construction herein disclosed, but what I do claim, is:-
