This invention relates to cutting devices and particularly appertains to a gauge and cutter adaptable for laying out linoleum and for ut: ting tile blocks and the like.

The primary object of this invention is to simultaneously measure and out a tile block or linoleum strip.

Another important object of this invention is to gauge the space between the edge of laid tile o flo n d the Well n to s mu neele out a tile o oo ng ock o eehferm 9 th measurements of the space.

Another important object of this invention is to reduce the time required for laying a pargueted block flooring or tile floor by providing a combination gauge and cutter, whereby various spaces may be gauged and simultaneously the blocks may be cut to a dimension in conformity with the space.

In the accompanying drawings, attention be? ing first directed to Figures 1 to 5, inclusive, the combination block cutter and gauge to in.- cludes a, frame 1; consistin o a ase plate L4 having a center opening I61 Longitudinal side walls 3 and 2D depend from the marginal edges o he base plate and are integral therewith, he id Walls av ng horizontally disposed flanges or corner shields 22 formed at their opposing ends. Afront wall 24 extends between the side walls and ball earin s 2.6 are mounted in th corne sh e ds or p sts .22.

A movable cutter 5.4 is slidably mounted between the b rs e utt r includin a block aving opposi g r uc d Q .$1ir ably mounted in the chann o t here; the ends .58 be m u ted on oil s ings to disposed in the channe s- A cut bl d .2 is anchored .in the lower end of the blo k n disposed in vertical alignment and cutting engagement with the fixed blade.

Means is provided for moving the ngvable blade, against the urge of the spring 69, into cutting relation with the fixed blade and includ s a squar bl ck 6.4 mounted paralle abov the movable cutter .54 and formed with p11..- center journaling ends .66 rotatably journaled in bearing blocks .68 mounted in he channels. Rings 10 are disposed concentric about the op.- posing ends of the blocks and mounted ba l bearings 12.. the rings being nsasee l on the upp r .fa o the cutter b ock .55- A hand e '14 projects lateral y from the ce te of the bloc and v t c sw ngin mov mentof the han results in a r ta y. move nt of the block the le hei s e nt l el mo d between the channel bars th re y produ g a d wnward mov ment oflthe moyablegcutter relative t the fixed edited Means is .Provided .oradjus ing the cu ters 3 and relaxing the tension on the movable cutter, the means including adjusting screws I6 threadingly disposed through the upper ends 42 of the bars and havin their inner or lower ends bearing on the journaling blocks 68 slidably mounted in the channels.

Means is provided for supporting a flooring block, such as tile or the like, I8 and includes a supporting member or bar 88 transversely disposed across the open center I6 of the base, the bar having an upstanding flange or lip 82 terminating in a horizontally disposed flange 84. The flange 84 is formed with outwardly facing shoulders, constituting a stepped flange, the edges of the floor blocks I8 being adapted to abut the shoulders and being supported thereby, as seen in Figure 2, it being noted that the flange 84 is coplanar with the upper cutting edge of the fixed cutter blade 58, so that the block is supported n the fixed cutter blade and on the flange 84. Means is provided for moving the bar 80 relative to the cutter, to enable the correct portion of the block to be sheared or cut off, so that the block is cut to the proper dimensions of the space between the outer edge of the laid blocks 86 and i 4 the wall 90, as seen in Figure 2. This means preferably includes a fixed gauge member or bar 92, which is bolted by bolts 94 or otherwise securely aflixed to the front bar 24, the fixed gauge member having a lower beveled end 98 terminating below the supporting

balls

26 and 34. As seen in Figure 2, the lower edge 96 of the fixed gauge member is adapted to engage the edge of be inclined relative to the axis of the cutters. Furthermore, the springs constantly urge the supporting member away from the cutters so that when the rods are positioned against the wall 90, the fixed member abutting the edge of the block 86, the supporting member is held in a substantially fixed position and the block I8 is therefore uniformly and evenly cut responsive to the outline formed by the gauge means.

Attention is directed to Figure 10, wherein another type of cutting means I26 is provided, the

1 same including the movable cutting assembly 56 the floor block adjacent to the wall, while movable gauge means 91 is provided and is operatively connected to the supporting member 80, so that the member is moved relative to the cutters, until the length of the block I8 between the supporting flange 84 and the cutter is workably equal to that between the edge of the block 86 and the wall 90. This means preferably includes a pair of elongated rods 98 and I00, which are slidably disposed through the front of the base and have rollers I02 rotatably journaled on vertical axes to their outer ends. Elongated slots I04 and I06 are formed in the base, parallel to the sides of the center opening, the rods being vertically aligned with the slots. The inner ends I88 of the rods are externally threaded and are disposed through axial passages formed in blocks IIO, nuts II2 being disposed on the opposite sides of the blocks to secure the rods therein. The blocks project upwardly through the slots and the opposing ends of the bar 80 are attached to the blocks by means of set screws I I4.

Means is provided for yieldingly retaining the supporting bar adjacent to the front of the base and away from the cutter, the means preferably including twin springs H6 which are horizontally mounted in a housing H8 on the under side of the base adjacent to the front wall 24, the springs being mounted on rotatably journaled hubs and being connected by means of a flexible connecting member I to the bar. In one embodiment, as seen in Figure 3, the flexible member extends through a transverse opening I22 in the bar and is knotted, as at I24.

In use, it can be seen, with respect to Figure 2, that the supporting member will be moved on the base relative to the cutter by means of the rods 98 and I00. It is to be particularly noted that the rods 98 and I08 can assume independent positions with respect to the bar 80, through the pivotal connection II4, so that the bar 80 can and the movable cutter blade 62 but having a fixed block I28 anchored between the channel bars by a wedge block or supporting block I30. Thus, a shearing action is obtained as the blade 62 is brought downwardly into shearing engagement of the fixed block I28.

For the purpose of forming and cutting blocks which are to be laid in diagonal lines, attention is directed to Figures 6 through 9. It will be noted that the same is similar to Figs. 1-5, but an attachment block I32 is provided. The block I32 is secured by screws I34 to the lower edge of the front wall 24, the wall having vertical bores I36 formed therein to accommodate the screws. The block I32 is horizontally disposed and extends rearwardly from the front wall, the block being parallel with the base. As seen in Figure 9, the block is provided with opposing inwardly and rearwardly directed end walls I31 and I38, the walls being adapted to abut against the inner slanting walls of adjacent floor blocks or panels.
