6 Claims. (Cl. 94-47) This invention relates to a tile laying machine which has for its principal object the provision of means for accurately and easily applying flooring tile to a suitably prepared surface so as to economically construct the tile flooring with a considerable savingsof the time and effort heretofore expended as necessary to manually perform the necessary operation.

This tile laying machine is especially adapted for use in laying tile on the prefabricated flooring of a trailer or like vehicle. The construction of this invention features means for applying various rows of tile to a suitable surface previously coated with an adhesive. The machine further provides means for applying pressure onto the tiles as may be necessary.

A special feature of construction of this machine resides in the fact that the compartments within which the tiles are stacked are of lesser dimensions in width than that of the tiles whereby the tiles will be supported in a flexed position so that upon release of the tiles from the compartments in which they have been stacked, the tiles will untiex to regain their complete width and thereby enter abutting relationship with the other tiles of a row of tiles.

Another novel feature or" construction of this invention resides in the means utilized for applying pressure upon the tiles previously dispensed from the machine whereby a substantial portion of the entire weight of the machine is utilized to properly set the tiles in the mastic or adhesive utilized to bond the tiles to the flooring surface.

Incorporated in the concept of the present invention are structures which enable selected spaces to be left blank as may be suitable in the trailer floor where there is to be located piping or where openings or for such other reasons as may be necessary. This means includes suitable cam elements which engage hinged plates to lift the stack of tiles out of engagement with the slide which is utilized to urge the tiles outwardly from their compartments.

An unusual aspect of the operation of this machine resides in the fact that the entire machine which will be pushed forwardly by the action of the slides urging the discharged row of tiles outwardly from the machine. In conjunction with the drive shaft which operates the mechanism for controlling the movement of the slide there is provided a brake for engaging the rails on which this device is mounted. It is to be understood that in lieu of the rails and carriage as disclosed various other embodiments of the invention may be devised which employ the basic principles thereof.

Still further objects and features of the invention reside in the provision of a tile laying machine that is strong and durable, comparatively simple in construction and manufacture, capable of saving a great amount of time and effort in the preparation of floorings, which is substantially foolproof in operation and which enables a better bond between the tiles and the flooring surface States Patent to be achieved than was heretofore possible by hand manipulation.

These, together with the various ancillary objects and features of the invention which will become apparent as the following description proceeds, are attained by this tile laying machine, a preferred embodiment of which has been illustrated in the accompanying drawings, by way of example only, wherein:

Figure 1 is a top plan view of the tile laying machine comprising the present invention;

Figure 11 is a partial perspectiveview of the portion of the slide adapted to engage a tile.

With continuing reference to the accompanying drawings wherein like reference numerals designate similar parts throughout the various views, reference numeral 10 generally designates a supporting table or the like of any convenient structure to which the side rails 12 and 14 are secured by any convenient means. A trailer floor Ill is positioned on the supporting table it] for the purpose of having a surfacing of tile placed thereon. It is to be noted that the rails 14 may be provided with a triangular or inverted V-shaped supporting surface for their guiding effect on the side wheels 16 and 13 of the carriage 2h. The carriage 20 includes a plurality of vertically extending partitions 22 and a rear wall 24- arranged so as to form a plurality of individual compartments which are generally indicated by reference numeral 26. The carriage 20 further includes a bottom tray 28 which together with the arcuately downwardly arched bottom Gil is canted at an angle downwardly and rearwardly. Hingedly attached to the carriage 2t) adjacent the rear wall 24 is a plurality of guides 32 adapted to permit a tile to pass between the tray 28 and the guides 32. The tray 28 terminates in a plurality of fingers 34 which are provided to properly deliver the tile to the heretofore prepared surface of the lower base 36 which has been covered with a suitable mastic or adhesive. The fingers 34 prevent any unnecessary or undue deleterious effect upon the coating of mastic.

The carriage 20 further includes

side runners

37 and 38 to which the rear wheels 4t and 42 are attached. Mounted on the carriage 26 is a pair of

bearing blocks

44 and 46 Within which .a drive shaft 48 is journalled. The drive shaft 455 is rotated in an oscillating manner by means of a crank arm 56 which is connected to the piston rod 52 connected to a piston within the cylinder 54 the operation of which is controlled by any suitable means such as hydraulic or pneumatic pressure as may be desired.

Secured on the shaft 48 are crank arms 56 which by means of links 58 are connected to slides 69 which are adapted to move reciprocatingly on the bottoms 30 of each of the compartments 26 and which are also adapted to move forwardly of the front end walls 62 of the carriage Zll, the walls 62 being shown in the embodiment of Figure 3 to be of reduced height for greater clarity. The slides 69 move and are guided in a suitable trackway 64 and slides 6d areprcvided with projecting heads 61': which are adapted to engage the lowermost of the tile stacked Within the compartments 26 to thereby urge the lowermost of the tiles rearwardly between the guides 32. and the tray 28 and outwardly to be dispensed by the fingers 34 onto the surface 36. Hence, upon rotation of the shaft 43 the slides 60 will be actuated to cause the tiles to be dispensed from the machine. it is to be especially noted that the walls or partitions 22 of the compartments 26 are so spaced that the width thereof is less than the width of the tiles stacked therein whereby the tiles will be forced to assume the concave upward shape as can be readily seen in Figure 3. lence, once the tiles have been expelled from the machine, the tiles will un flex to thereby compensate for the space taken by the width of the partitions 22 and provide abutting seams for a better floor surface. The stacks of tiles are held in a secure relationship by means of weights 68 welded or otherwise attached to arcuate plates Ill which are adapted to further maintain the stacks of tiles in their flexed condition.

There is separately journalled on the carriage 2 by means of suitable bearing blocks 72 a transverse rod 74 on which any selected number of cam elements '76 can be attached. The cam elements 76 are adapted to engage a contact member 78 extending upwardly from a plate till which is pivotally mounted as at 232 to the front wall 62 of the carriage 20. Hence, upon rotation of the rod 74 using the handle lid provided therefor, the plate 30 will be pivoted so as to lift the stack of tiles out of engagement with the slide fill. lit is to be noted that cams can be of such shape and so positioned that a quarter turn or 7 less in either direction will serve to prevent the slide 6d engaging the tiles within selected compartments 2-6 to thereby assure that a blank insofar as the tiles are concerned will occur at a particular position. Hence, in locations where there are necessitated wheel openings, piping openings, or the like, no tile will be placed on the flooring since such can be accomplished at a later period in the construction of the trailer.

A transverse shaft 86 is provided and is suitably journalled in eccentric bearings 8% whereby upon rotation of the handle 99 the shaft as will be vertically displaced. Mounted on the shaft 86 is a plurality of rollers 552 of substantial wei ht which are adapted to engage and press downwardly upon thedispensed tiles of the previous row of tiles. After the floor has been tiled shaft 86 is rotated to lift the rear of the machine so fingers 34 are raised above tile and the machine can be pushed back over tile to reroil it and return machine to starting position. The rollers 92 may be formed of metal or of suitably resilient material as may be desired. A spring assembly -t is provided for applying some of the weight of the machine to rear wheel 42.

Attached to the drive shaft 48 is a brake actuating arm '26 carrying a contact member 98. This contact member 93 is adapted to engage another contact member 100 mounted on a rod 102 extending through

spaced plates

104 and 106. The rod W2. carries a collar 108 and a spring 110 biases the plates ltld and lt tl. Mounted at the lower extremity of the rod MP2 is a brake shoe 112 which is adapted to engage the track 12. This brake assembly provides means for stopping the forward motion of the machine caused by the fact that the slide 60 will press the rearward end of the lower tiles being dispensed against the forward edge of the previous row of tiles which will best cause the machine to be moved forwardly. The braking action of the brake assembly is of course timed by the position of the brake actuating arm 96 on the drive shaft 48.

Since from the foregoing the construction and advantages of this tile laying machine are readily apparent, further description is believed to be unnecessary.

However, since numerous modifications will readily occur to those skilled in the art, after a consideration of the foregoing specification and accompanying drawings, it is not intended to limit the invention to the precise embodiment shown and described, but all suitable modifications and equivalents may be readily resorted to.
