SPECIAL MERITS OF EXHIBITS. 141 



The " E " mill is made either single or double, and is intended for light power 

 and a small force of hands, for wliich purpose it is well adapted. It is furnished 

 with a rack and pinion head-block that opens 36 inches, and sets accurately by six- 

 teenths. Three men can run this mill successfully. 



They also have an edging table, in which the guide-rail is supported on a cast- 

 iron frame, made in a form to secure the greatest strength with the lightest weight. 

 It is readily taken apart, for transportation, and set up again, and is furnished 

 with counter-shaft for getting up speed, and a gauge for ripping to width. 



They also have a billet saw that is convenient and safe to operate. The sliding 

 table can not get off the guides. 



They also exhibit a swing saw, wliich is well and strongly made, and furnished 

 with means of being securely hung. The boxes for mandrel in lower end are very 

 secure. 



Earjlc Machine. Works, iThdianapoh. Exhibit one of their Pony " C " saw mills, 

 which is well designed and well made, of good material. This mill is well 

 adapted to do neighborhood sawing with a light power, such as is generally used 

 for threshing. It may have a top saw added, and used as a double mill. The 

 mandrel runs in self-adjusting boxes, and is very long, with driving pulley outside 

 of frame, giving four and a half feet room for off bearer between belt and saw. The 

 head-blocks set any thickness by.screw feed, worked by a lever, and are conve- 

 niently operated for sawing tapers. The sawyer can, from one position, control the 

 engine and feed, and also set the log. 



They also exhibit a set of Meiner head-blocks. These head-blocks have been 

 long and favorably known to sawyei^s as being accurate and convenient in setting, 

 simple and durable in construction, and filling all the requirements of a first-class 

 head-biock in a very satisfactory manner. 



Band Saw Mill, by Sinker, Davis & Co., Indianapolis. This is a large and im- 

 proved mill, capable of sawing the largest logs into lumber at the rate of from 

 15,000 to 25,000 feet per day, owing to the timber and power used. In this mill 

 the objections or obstacles heretofore found in ifsing the band saw for manufactur- 

 ing lumber rapidly seem to have been overcome, as was demonstrated on the 

 ground during the fair, where it attracted marked attention from visitors gener- 

 ally, and from saw mill men especially. The great saving of time and timber, 

 which is wasted in chopping for the upper saw mandrel of the circular mill, in 

 large logs, and the great saving in all timber by using so thin a saw must soon 

 bring this kind of saw into general use, as good timber is rapidly becoming scarce 

 and more valuable. It is claimed that this mill will cut six 1-inch boards from 

 a flitch 6 5-16 thick. In operation on the fair grounds it cut straight lines and 

 very smooth lumber. 



Potts' Hydraulic Brick and Tile Machine, by Vinton Iron Works, Indianapolis. 

 This is a new style of brick and tile machine, and differs from others in many im- 

 portant particulars, the principal one being in the manner of getting motion and 

 presriure to the plunger. This is accomplished by hydraulic pressure, produced by 

 » set of three plunger pumps forcing water into a cylinder, where it operates on
