Although: everyeffort made in the formins machines: M1 to; advance: the; tworows of: tile lengths X at a uniform rate:ofifspeedadifliculty is experienced in having one row" move; ahead; of

Inorder to; obviatecthis difficulty and to. stabilize: the; advancing, movement of; the twmrows; a series oifvertically disposed arms l8 are pivoted; adjacenttheir" uppenendsto: brackets l8 suitablit secured: to the outer: side of each tray Hi It; will: beunderstood: that there; are serieslof: longitudinally-spaced?trays H for supporting;the-tile;,a pain of; trays supporting each severed-section: The lower endstofthearms l8 engage in a cam track 2-01which. is so designed-to impart outward: swinging movement to the? lower end. of the; arm at; predetermined. periods irrthe adv-.ancing; movement-of thercarrier; as will here.- inafter. be. described.v

A. helical coil spring 2011: is disposed between thaupper. end portionaoieach. arm. 18 and the bracket. lit tQ-urgathe lower endiof the. arm into engagement. with. the. cam. surface. on the. cam track 20.

H, the purpose for which will hereinafter appear;

Associated with the cam track" 20" at a point intermediate the receiving end ofthecarrieruand the ad'iacenttfleX; Itwill be V readily from the of tile in laterally spaced, disposed rovvs,a horizontally movable carrier rcsure imposed by the spring fingers 2| is exerted for a Very short interval of time, whereupon the respective arms I8 are released and the spring 20a abruptly rocks the spring finger away from the adjacent tubing. The arrangement is such that each of the lengths of tubingis simultaneously engaged by thespring'finge -andalso;;i s released atthe same time.

Near the discharge end of the carrier C; the cam tracks 28 are similarly provided with cam surfaces 23 to effect w I Y r 7 to exert pressure against the rear end of each severed tile section from the carrier. each tile section, the front end of such section .10 similarroc i l movement just prior to its discharge ,4 By :clampingthe rear end of is held in its horizontal position; so that it will engage a conveyor D. It will be manifest that without exerting such clamping pressure uponeach tile section, the front end of the til would tend to incline downwardly as the forward tray moves downwardly from its horizontal position. Heretofore, it ha been necessary manually to remove the tile sections from the carrier and place them on the conveyor D. Such manual labor is eliminated since the tile sections move carrier to the conveyor D. As soon as the tile section, is delivered to the conveyor D, the clamping pressure is released from the rear end portionof'the tilesection.

It is to be understood that numerous changes in details of construction, arrangement and operation may be eifected without departing from the spirit of the invention especially as defined in the appended claims. a

What I claim is: V l

1. The method'of forming clay tiles consisting in horizontally advancing two endless tubes in parallel side by side relation upon an endless carrier, applying pressure advance to equalize the currently severing the tubes into predetermined sections, and applying pressure to the rear'end portion of each section at the time of discharge from-thecarrier to cause same to maintain its horizontal position'thereof. a a

2. Tile feeding and severin mechanism comprisingmechanism for advancing alength of tile, cutters operating in timed relation to the'advancing movement of the tile for the tile during advancingmovement, and means for automatically rendering said arms effective at a predetermined point in the advancing movement of the tile. 7 a V 3.
