T LE-recruits MACHINE.

Application filed September 22, 1926. Serial 160. 137,082.

This invention relates to tile fettlingnia chines, more particularly to a machine for smoothing or trimming the edges of t le after leaving the tile press in which they are -formed and before they are fired.

It is among the objects of this invention to provide a tile fejttling machineofsimple and durable. mechanical construction, and in which all of the movable'elements are actuated from a common driving source.

Another object of this invention is to i provide a tile fettling machine which shall be adapted to fettle or smooth clay tile in relatively large quantities, the machine being adapted to receive all of the tile from amultiple tile-forming press and continuously convey the tile away from the press through a number of fettlingmembers and cleaning brushes for smoothingthe imperfectly formed edges and forchamferingthe same if desired.

Tile fettling machines have been heretofore proposed which function to trim the edges of tile by passing the tile on a movable support-through the fettling members tobring the latter to act upon opposite edges thereof,-and to subsequently turn the tile by suitable means to present the untrimmed edges of the tile to additionalfettling members. The prior art devices are objectionable mainly on account ol-their limited capacity for handling the tile. This has been done by providing an obstruction in the path of the tile which was of such form as to cause the tile to pivotor turn on its support. to bring the untrimmed edgesin alignment with the fettling members, the turning means being capable of handling but a single tile at. a time; v 1

In accordance with the present invention means are provided for turning a plurality of tile passing through the fettling devices simultaneously, whereby the capacity of the machine is materially increased. In addition means are provided for guiding the tile as they pass from the tile-formingpressto the fettling members in such a manner that after they have been acted upon to trim some of their edgesthey are cond'ucted to the turning mechanism which rearranges the tile on their movable support to bringthem in proper working alignn'ient with subse quent or additional fettling members.

Another feature of the present invention is the provision of dusting or smoothing rollsor brushes which act upon the tile after they have been subjected to the fettling operation to remove any unevenness or loose particles adhering. thereto prior to subjecting the tileftoa coating operation for producing a glaze or finish thereon.

, In. the accompanying drawings constituting-apart hereof and in which like refer ence characters designate like parts, Fig. 1 is a top plan view of a fet-tling machine embodying the principles of this invention; Fig. 2 is a side elevational view thereof partially in section; Fig. 3 is a vertical sectional view partially, in elevation, of a novel form of fettling member, and Fig. 4 is an, elevationalview of a portion of the fettling do vice illustrating a tile being acted upon by a pair of fettling members.

Referring to Figs. 1 and2 of the drawings, the structure therein illustrated comprises a frame or base consisting of a pair of slde frames 1 supportedon a standardQ formedof pipes or other structural members suitably joined or secured and reinforced to provideadequatestrength to the machine frame. .Upon the ends of the side frames 1 and at the intermediate portion thereof a plurality of rollers or spindles 3-and 4: are rotatablyjournaled, the spindles 3 carrying an'endless conveyorbelt 5 and the spindles {la similar belt .6, which, respectively, pass around driving drums '7 and 8. actuated by a common drive belt 9passing around a sheave or pulley 10 of a countershaft 11 which is actuated by a drive motor -12. Suitable slackadjustment or tension devices 13 are provided for-the belt 6 to take up the slack the count-ershaft 11 by belts 17 and.18.

' A plurality of fettling devices such as is shown in 3, are mounted on the top portion of the machine above themoving conveyor belt 5 by means of angle brackets 20 which extend across the side frames 1 trans versely of the path of movement. of the belt 5'. The fettlers consist'of discs 21 which are secured by a screw 22 and collar to a yieldable supporting strap 2 1. which is clampedto an adjustable block '25 mounted the beltand to keep it taut at the upper may also be angularly adjustable by moving the same in its dove-tailed slot 29 and secur-.

ing it in its adjust-ed position by the set screw 30. a

The purpose of making the fettling member of disc shape is to permit adjustment of the fettling edge which in the disc member comprises loosening the screw 22 and rotating the disc 21 a fraction of a turn until. a clean and neat cutting or trimming edge is presented to the tile with which it comes into engagement.

As shown in Fig. 1 a plurality of guides 32 are secured by angle bars 33 in parallel re- 'lation to constitute guideways for receiving individual tile as it enters upon the conveyor belt 5. The guides are correlated with the fettling device 21 in such a manner that I the tile passing therethrough contacts with the fettlers in the region where they are to be trimmed which is usually the edges, which, inmost instances, are chamiered or beveled as they pass through. the fettlers.

After the tile has passed through the guides and the first group of fettlers 21 they pass along the conveyor belt 5 in a row extending across the path of movement of the belt until some of them engage a baflie member 35 and some a baflle member 36, W l'llCh are pivoted to a cross brace 37 and one of the angle bars 20 respectively, as shownand are adapted to swing through arcs limited by the stops 35 and 36 respectively, The battle members are of such width as to en gage a plurality of tiles simultaneously and since the adherence between the tile and their movable support 5 maintains Contact of the tile with. the baffle member they will be simultaneously turned through an arc as illustrated by the dotted line to rearrangetheir position in a manner that will bring the untrimmed edges, that is, the edges that were not acted upon bythe first fettling device in alignment with the fettling-members in the intermediate portion of the machine. After the tile have been rearranged or turned as shown in the illustration, they are conveyed through theadditional fettling device which smooths or trims their edges The tile then passes underneath the brush 14 which removes the dust or fine particles from the surface of the tile and subsequently passes over the brush 15 which. cleans the underside of the tile.

When the tile has passed out of contact with the battle arms 35 the latter spring back to their normal position which-is transversely of the path of movementof the conveyor belt 5 until they become again engaged-by tile movinginto contact therewith. For the purpose of maintainingthe bafflemembers in their normal position a yielding restraining means such as a rubberstrap or spring may be applied in the region of its pivotal 'oint. a

3 It is evident from the foregoing description of the-invention that tile fettling machines made in accordance therewith provide simpleand efficient means for fettling all of the edges of a plurality of tiles simultaneously by passing them in rows through suitable guides underneath and in engagement with fettling members, and for automatically turning the tile after they 'areacted upon by one group of fettling devices to present the untrimmededges to an additional group offettling members to finish the tile.

It is further obvious that tile.;ffet tl ing machines of this kind are especially adapted for fettling tile received from multiple tile forming presses having a relatively large quantity production.

Although one of the embodiments o f the invention has been herein illustrated and described it will be obvious to those skilled in the art that various modifications may be made in the-detailsof construction andin the arrangement'of the severalcooperating parts without departing from the principles herein-set forth. 1
