honors of the Institute. This hammer has also been inspected in 

 actual work, with the most satisfactory evidence of its effectiveness 

 and manageability. 



No. 172. Steam Forging Hammer. (Richard Dudgeon.) The 

 work and design are both good, embodying simplicity and strength. 



The peculiar feature is the octagonal piston rod, which gives 

 great force to the blow, and keeps the hammer true to its work 

 without guides. It is easily controlled, and gives variable blows, 

 adapting it to different classes of forging. We recommend it to 

 the consideration .of the Institute for its honors. 



No, 1180. Power Press. (N. C. Stiles.) Its merits are, good 

 design for strength, good material, excellent workmanship; device 

 for setting the dies with great facility, and without injur}-, and 

 means of regulating the throw of the press to the nicest possible 

 point, thus saving the wearing of the dies. 



This machine is strictly first class in every particular, and wo 

 therefore earnestly recommend it for the first class honors of the 

 Institute. 



No. 235. Power Press. (E. Brown.)* Its merits are, good design, 

 good material and excellent workmanship. This machine is for 

 punching and drawing up that class of work used for small covers, 

 as can tops, cartridge cases and powder flask nozzles. It per- 

 forms these two operations at each throw of the press, with the 

 greatest precision and rapidity. The good qualities of this machine 

 recommend it to the highest honors of the Institute. 



No. 1181. Foot Punch Press. (N. C. Stiles.) This is decided 

 to be a first class tool and worthy of notice. 



No. 236. Foot Punch Press. (E. Brown.) This is decided to 

 be a first class tool of its kind and worthy of notice. 



No. 336. Hydraulic Spring Tester. (C. Graham.) Its merits 

 ai'e, good design and workmanship, good material and the ease 

 with which springs of great power can be tested arid the accuracy 

 of their tension registered. We, therefore, commend it to first class 

 honors. 



No. 131. Blacksmith's Forge and Tuyere. (James Paterson.) 

 Its merits are: 1. Good design and material. 2. Allowing the air 

 blast to reach all parts liable to burn out, keeping them cool and 

 heating the air as is comes to the fire. 3. The conical tuyere 

 and its seat, which, by a simple lever, allows the ashes to fall 

 out of the way. 4. The ease with which the fire is cleared of 

 cinders.
