42 MECHANICS AND MANUFACTURES. 



saving the breath of the operator, they are far raore powerful than those 

 horns sounded by the mouth. 



Flags for railroad crossing men were shown, which, when induced, 

 gave forth a sharp sound of warning of the approaching train. Whis- 

 tles put in operation by the foot, and many other instruments of sound 

 were displayed. 



In addition to the numerous Alarms, the Co. had one of George F. 

 Blake & Go's large Steam Force and Fire Pumps on exhibition, and 

 also furnished a smaller one for feeding the boiler, aquariums, etc., 

 they having lately entered into the manufiicture of this celebrated and 

 excellent pump. A better working pump was never exhibited than the 

 one quietly forcing the water (from the artesian well sunk near the 

 spot) into the boiler, against the ninety pounds pressure of steam per 

 square inch, and at the same time mildly feeding the noble trout in the 

 aquariums, and giving drink to the thirsty Burleigh Drill. Besides 

 the manufacture, the card over the pump informed that the company 

 turn their especial attention to repairing steam pumps of all makes. 

 Certainly their exhibition was a good one, and the committee ac- 

 knowledged its appreciation by a handsome gratuity. 



In passing through the hall, it was our pleasure to come suddenly 

 upon a shoe manufactory, in full working order, and, upon inquiry, we 

 found that our friends, E. M. Dickinson & Co., had removed some of 

 their famous Pegging and Sewing Machines down to the Fair, in order 

 that the public might see the process by which the soles of shoes are 

 sewed and pegged by machinery. These machines are perfect won- 

 ders, driving from 700 to 800 pegs, and making from 300 to 400 

 stitches per minute, and doing their work in the most perfect manner 

 — actually driving pegs better than can be done by hand, because 

 every peg is driven home, without being broken. 



The New England Machine Co. had upon exhibition one of their 

 new Pattern Planers, upon which they claim many important improve- 

 ments. One of these is an improved cap, or bonnet, for protecting 

 the rolls from clogging with shavings, which causes indentation upon 

 the stock while being planed. This is a desirable feature in such a 

 machine, and one which will bo appreciated. AVe understand that 

 this same machine is now upon exhibition at the Fair of the American 

 Institute at Xew York. We wish our friends much success in its 

 manufacture. 



The Kollstonc Machine Works, which are noted for the large variety 

 and excellent quality of their wood-working machines, had, upon this 

 occasion, a very fine collection, embracing one of their Patent Ward- 

 well Sawing Machines, a Band Saw, a Planer, and a Gauge Lathe 

 with Kilburn's Patent Shave Knife attachment, and one of their Flint's 

 Patent Self-setting Saw Mills. 



The Wardwell Patent Saw Bench is well known. They have made 

 several hundred of them, and they are running in nearly every part of 

 the world. This Machine carries two Saws, (^a cutting-off and a split- 

 tino; saw) in a swinoinir frame. Thev are so arranged that each can 

 bo instantly changed for the other, and can be instantly set for cross-
