CEMENT TESTING APPARATUS 



2229 



2229 -CEMENT TESTING MACHINE, Olsen's New Automatic Shot Form. The 



principal advantages of this machine are as follows: 



The machine is automatic to its full capacity and is not touched from 

 start to finish of test. The instant the briquette breaks, the breaking lead is 

 read on the dial of the scale. 



The load is applied with absolute smoothness, and impact from falling 

 shot is eliminated. 



The cut-off on the shot kettle is practically instantaneous. All shot that 

 has escaped from the kettle has already done its work and the column of 

 falling shot in the air when the specimen breaks is therefore weighed as it 

 should be. 



A new grip which brings the strain uniformly on the specimen is used. 



The briquette hangs clear of the frame of the machine, giving plenty of 

 room for the hands when adjusting specimens. 



This is widely used and thoroughly satisfactory outfit; 1,000 Ibs. capacity; length, 

 24 inches; height, 26J4 inches; weight, 50 Ibs.
