Abstract: 23,432. Yingling, F. B. Oct. 17, 1912, [Convention date]. Printing-apparatus combined with tile-measuring machines.-In a machine for measuring the warpage and length of tiles, and for printing upon them indications of these measurements, the tiles are carried by an intermittentlymoving feed-belt formed by chains 2 with cross slats 3 into warp and length measuring devices W, L respectively. The tiles rest against the leading face of the slats. The warp-measuring mechanism, which is shown in Fig. 2, comprises a vertically movable rectangular framework 30, 32 over the lower bars 32 of which the feed-belt passes, so as to be moved with it. When the tile is in position the feed-belt stops and the frame 30, 32 and feed-belt are lowered, the tile T then resting on two fixed pins 40 at diagonally opposite corners and a steadying pin 41. The warpage along the diagonal on which the pins 40 lie is measured by a central movable pin 45. The long arm of the lever 60 carries a vertically sliding yoke 65 with a knife-edge dog 66, the position of which thus corresponds to that of the measuring-pin 45. A ' selector,' having an inclined face with pointed teeth 71, is then moved by an arm 73 actuated by a spring 92 until one of its notches engages the dog 66, and in its movement rotates a rubber or other type-wheel 200, Fig. 3, by means of a rack 203 connected to the selector by a rod 55. Owing to the inclined face of the selector 70, its movement, and hence the position of the type-wheel, depends upon the height of the dog 66, and thus upon the position of the measuring-pin 45. The type-wheel is carried by an arm 57<a>, pivoted at 57, and when thus positioned it is dropped on the tile by the action of a cam 83, and prints a character indicating the warpage of the tile. The printing-wheel may be inked by a roll 206 carried by a pivoted arm 207. It is then raised and the tile is unclamped and moved away by the feed-belt. In Fig. 2 is shown another form of printing-apparatus, in which a slide 51, actuated by the selector 70, brings the required type plunger 52 under a hammer 56, carried by the arm 57<a>, which causes it to print through an ink-ribbon 54. In the length-measuring device L the tiles come to rest between a fixed abutment 100, adjustable by screws 101, and a measuring-pin 103 carried by a fork 104 attached to an arm 106. The measuring-pin is released when the tile is in position and pressed against it by a spring 110, a dog 107 carried by the arm 106 and guided by an oblique rail 108 being moved correspondingly. A selector 109 co-operates with this dog and operates a type-wheel 250 in substantially the same way as that already described in connexion with the warp-measurer. It is moved forward under the action of a spring-operated arm 119, when the latter is released by a cam 115, and rotates the typewheel to a position corresponding to that of the dog 107, which limits its forward movement. The type-wheel is then dropped to print the proper length-denoting character on the tile and raised again by the cam-operated arm 125<a>. The selector 109 is then withdrawn, the measuring-pin retracted by the action of the cam 114, and the tile moved away.
