Thisarrangement allows a continuous action of themachine so that the pieces can be taken awayand replaced without stoppages or interruption ofthe work. In the ordinary beetle the fallers being ofvery thick, hard close-grained wood and coveredwith lead, flatten the cloth and give it a certainappearance and a peculiar feel and have been made to increase the speedand production. Mather and Piatt have inventeda machine, dispensing with cams and fallers, andworking with eccentrics. MACHINES EMPLOYED IN FINISHING. 249 This machine, as shown in fig. 98, page 250 B,has three cast iron beetling beams, revolving cast irondiscs, and is made with any number of hammers up. Fig. 97.

Whereas the beetle previouslydescribed could only strike 60 blows per minute,the hammers of this patent Beetle give elastic 250 FINISHING IN GENERAL. blows to the piece with great rapidity (450 blowsper minute) and every variety of beetle finish maybe produced more economically than by the oldand slower methods. One of these machines with14 hammers does as much work as seven ordinaryBeetles with wood fallers raised by cams, furtherit requires only 6 HP instead of 15 to 16 HP,and takes up much less space; viz: 12 6 by5 6 by 10 0 in height. In the first machines of this kind the hammersfollowed the movement of the eccentric and wereconsequently wanting in elasticity, however, theyare now furnished with semi-circular steel springs,provided with leather straps, on which the ham-mers are fastened; the shocks and rebounds sohurtful to the machine and fa
