only to such consideration as would be awarded to fair class tools, 

 such as are found on sale. Its peculiar feature is the quick back 

 feed. 



No. 541. Shaping Machine, large. (New York Steam Engine 

 Company.) It is a remarkably well made tool. Its design, mate- 

 rial and workmanship, and its range of work, entitle it to honors 

 of first class. 



No. 872. Shaping Machine, small. (H. D. Stover.) Its mate- 

 rial and design are excellent, and its workmanship and finish first 

 class, and is every way worthy of high consideration as a machine 

 for making work for the duplicate or interchangeable system, as 

 well as the ordinary work of the machinist. We respectfully 

 recommend it to honors of the first class. 



No. 841. Drop Hammer. (Golding, Cheen^'- & Co.) Its merits 

 are, that it dispenses with the gearing attached to the rolls raising 

 the hammer, as usually constructed. Its workmanship is good, and 

 the material is well disposed of to make it capable of resisting the 

 concussions to which this class of machines is exposed. We cor- 

 dially commend it to the highest honors of the Institute. 



No. 1182. Drop Hammer. (N. C. Stiles.) The. method of 

 raising the hammer by an endless belt is entirely novel. The 

 theoretical objections to which (for heavy work especially) can 

 only be set aside by experience, wliich the limited time of an exhi- 

 bition will not give. It is decided to be worthy of high conside- 

 ration by the Institute. 



No. 100. Compressed Air Forging Hammer. (Thomas Prosser 

 &, Son.) This hammer is a machine of great merit. The construc- 

 tion is highly ingenious. The material and workmanship strictly 

 fii'st class. It delivers a firm, hard blow. It can be operated with 

 great rapidit}-, and it instantly lifts from the iron, so that it is not 

 cooled in hammering. It is under perfect control, so that a large 

 range of work can be executed by it. 



Having seen this hammer in actual working operation, we most 

 earnestly recommend it to the first class of honors of the Institute. 



No. 970. Air Spring Hammer. (Charles Merrill -& Sons.) 

 This hammer combines great simplicity and strength; utilizing the 

 poAver generated by the upward stroke, and increasing the force 

 of the downward blow; the working parts are durable, and not 

 liable to get out of repair. The application of the device is 

 entir.ely novel, and we mark our appreciation of the merits of the 

 machine by earnestly recommending it to receive the fii'st class
