MACHINE FOR CUTTING TILES.

To all whom it may concern:

Be it known that I, ALBERT citizen of the United States, residing at New York city, Rosebank, borough of Richmond, county of Richmond, and State of New York, have invented certain Improvements in Machines for Cutting Tiles, of which the following is a specification.

My invention relates particularly to ma- \chines for cutting interlocking tiles adapted for coverings for floors and like surfaces, the tiles being cut from rubber or a composition of suitable materials penetrable by a knife, which interlocking tiles may be of any design that fancy may dictate.

The purpose of the invention is to provide a machine of the character mentioned that will cut tilin adapted to be arranged in closely groupe series, or series spaced one from the other or spaced from a border, or so cut the tiles as to produce a border only of any desired type.

Another purpose of the invention is to provide a machine that is positive in action and which is rapid in operation, and which will also cut any shape of tile from sheet material rapidly and without waste and so that the tiles, if of an interlocking type, will perfectly join together.

In the drawings that serve to illustrate my invention, I have shown the improved type of machine, but I do not confine my self to the exact construction illustrated, as details may be varied to suit conditions.

In the drawings-Figure 1 is a front elevation of the machine, parts being broken away; Fig. 2 is a side elevation of the same; Fig. 3 is a partial elevation of the plunger head, and a knife fitted thereto; Fig. .41 is an end view of the knife head for the plunger; Figs. 5, 6 and 7 are diagraphic views of cut tiles of the interlocking type, illustrating a compact formation, a border formation, and border and body format-ion separated somewhat widely from each other. Fig. 8 is an enlarged detail view showing certain features of construction of the worm gearing comprised in the means for actuat' ing' the feed rolls of the machine.

In Figs. 5, 6 and 7, I have illustrated diagraphically one form of interlocking tile S. JANIN, a

that can be produced by the improved machine to be hereinafter described. In Fig. 5 the improved tiling is shown as closely grouped together, the tiles being designated as c and the sheet of tiles as G. In Fig. 6 the sheet C is shown provided with borders 0" also produced by the improved machine, which borders are somewhat close together, and may or may not be used, in connection with a closely grouped body portion in the center of the design; whereas in Fig. 7 the sheet C is also shown as provided with borders that may be used alone or in connection with closely grouped tiling, and the said borders, which are designated as 0 and 0 are shown spaced some distance apart, and the spacing between the border or borders and the body portion of the design may be greater or lesser, as occasion may demand.

With reference to the machine shown particularly in Figs. 1 and 2, a base A, is provided of any approved formation, but the top of the said base is in the form of a flat table 10. On this table adjacent to the side portions of the base, standards 11, are secured and these standards at their forward lower portions are preferably cut away as is shown in Fig. 2, and at such point are connected by a brace 11*, shown in Fig. 1, and the said standards are likewise strengthened by ribs 11 A box bearing 12, of any suitable description is mounted upon the upper end of each standard 11, and in these bearings, a drive shaft 13 is mounted to revolve, being provided with a crank 14, between the said bearings, as shown in Fig. 1. The upper, preferably flattened, enlarged portion of a link 15, is pivotally connected with the crank 14, and the lower end of the said link 15, is made to enter between box bearings 17*, located at the upper end portion of a plunger 17 being pivotally connected with the said plunger by a pin 16, passed through the link and into the said bearings 17*. The link 15, may be of any suitable formation.

A head 18, is attached to or made integral with the lower end portion of the plunger 17, which head may be of any suitable from the base A. At one end of the roller shaft 22, a gear 25, of desired size is secured and the feed roller 23, is shown provided with flanges 22 at its end portions. A sec- 0nd feed roller 26, of lesser diameter than shaft 13.

the roller 23, is mounted to turn above the said roller 23, and the material in sheets is fed by the said rollers, onto the aforesaid table 10. The roller 26, is secured to a shaft 27, mounted in boxes 28, slidable in frames 29, erected upon the upper front side portions of the base, and set screws 30, or their equivalent, pass through the said frames 29, and into the said boxes 28, whereby, to adjust the roller 26, toward and from the roller 23, and the said set screws 30, likewise serve as mediums to apply tension to the upper roller 26.

At the right hand end of the upper roller shaft 27, a small gear 31, is secured, that meshes with the lower and larger gear 25, so that the speed of the two rollers will be more or less uniform.

A vertical shaft Set, is mounted to revolve in a bearing 32, at the outer side face of one standard 11, and likewise revolves in a hearing 33, located at the right hand side of the base A, as shown in Fig. 2. This shaft 34:, is provided with a bevel gear 35, at its upper end, that meshes with the gear 21, of the At the lower end of the said driven shaft 34, a feed gear B, is secured in any suitable manner, and the body or hub portion of this feed gear, is provided with a worm 36, adapted to mesh with the teeth of the larger driving gear 25, as shown best in Fig. 2. The said worm 36, at its upper end portion, is provided with a removable section 38, that is adapted to be fitted in a groove or channel 39, in the face of the hub or body of the feed gear B, as shown in Fig. 8. When the removable section 38, of the worm is in position it will convey a maximum feed to the feed rollers, and when the said section 38, of the worm is removed, the

ear B, will impart a minimum feed to the said feed rollers 23, and 26. The removable section 38, of the worm may be held in position in any approved manner. As shown herein, a threaded aperture 461, is produced in the channel 39, and a corresponding aperture 11*, is produced in the aforesaid removable worm section 38, and a pin or the equivalent is passed through the aperture 4:1 into the aperture ll.

lVhile the cutting of tiles is being effected, it is necessary that the feed rollers 23, and 26,. should remain stationary. To that end, the body or hub of the feed gear B, is pro vided with a tooth 40, between the widest spaced portion of the worm 36. This tooth at the moment the knife reaches the sheet from which the tiles are to be cut, enters between the teeth of the larger gear 25, and holds said gear stationary during the cutting operation, the length of the tooth 10, being just sufficient to release the said gear 25, at the moment the knife has traveled upwardly to clear the sheet of material fed thereto, and immediately upon the release of the gear 25, from the teeth 4E0, the feeding operation is continued.

As shown in Fig. 4, the head 18 of the plunger 17, is cut away at its sides to receive clamping strips 42, that extend below the underface of the said head 18, and the projecting portions of the clamping strips 42 receive between them, the head 43, of a knife H, of desired pattern. Bolts 45, are utilized to secure the clamping strips 42, to the said head 18 of the plunger, and the head 13, of the knife.

In the operation, as long as the worm 36, is in engagement with the gear 35, the feeding of the sheet material to the knife is continued, the knife being at such time in an upper position, and the feeding likewise continues until the knife has descended and closely approached the material, at which time the tooth 10, which may be termed a stop-tooth, engaging with the gear 25, prevents its rotation, and as stated such engagement is continued while the knife is cutting through the material and is being withdrawn therefrom. \Vhen the pattern is such as is shown for example in Figs. 5 and 6, but a short feed is required owing to the comparatively close spacing of the cuts 0, 0, between which the rows of tiles are produced, as indicated in said Figs. 5 and 6, and at such time the detachable section 38, of the worm is removed, but when the spacing between the cuts 0", 0 is greater, as indicated in Fig. 7, a longer feed is necessary, and at such time the removable worm section 38, is secured in position on the feed gear B.

This machine is very simple, and is particularly well adapted for the purpose intended, being applicable for cutting tiles or similar articles of any design by changing the knives, and it is also evident that the machine can be economically constructed and that it is positive and reliable in its operation.

What I claim as new and desire to secure by Letters Patent is carried by the table, a plunger having vertical movement in said uprights, a drive shaft for the plunger, feed rollers located in front of the said table one above the other, the uppermost roller being of lesser diameter than the lowermost roller, and gears secured to the shafts of said rollers, which gears are in mesh, the upper gear being smaller than the lower one, of a shaft driven from the actuating shaft of the plunger, a feed gear carried by the said driven shaft, a worm on said gear meshing with the teeth of the larger roller gear, and a stop tooth also carried by the said feed gear at a point between the diverging ends of the worm for the purpose described, the said worm provided with a removable terminal whereby the feed of the rollers may dered greater or less.
