As manyas 2,000 blocks per hour can bemade on a single press of this de-scription. The large demand madeby architects for ornamental brickfor embellishment of the exteriorof buildings has resulted in theconstruction of an automatic-powerbrick-repressing machine, which isconstructed by the same manufac-turer, anil which is illustrated inFig. 7. Here the brick, after be-ing struck out by hand or machine,and allowed properly to dry, arej)!ace(l on the feeding-table by anattendant, or run indirect from theoff-bearing belt. Tliev are then.

Thence they are placed upon barrows or trucksby an off-bearer. Two men, or rather two boys, are retjuired to ojierate it. The capacityof tills machine is from 10,01)0 to bricks per day. Not merely are brick-re|)ressingmachines adapted to the production of ornamental bricks, but it is fastbecoming the practiceto repress all brick ^ed for paving purposes. It is claimed that paving bricks so rcj)ressedwill not flake or laminate, nor crack by the contact
