MECHANICS AND USEFUL AKTS. Ill 



frame. The cutters consist of long straight edges, of the same length as the 

 machine is wide. Price $500. 



Morse's Patent Planing Machine. This machine planes both sides of the 

 lumber at once, tongues and grooves at the same time, and if the board is 

 wider at one end than the other, reduces it down and brings it out finished, 

 of equal dimensions throughout. The tongueing is done in a peculiar manner, 

 viz., by simultaneously grooving the board on both sides, thus cutting through 

 and leaving a smooth rounded tongue, which is superior to the tongues made 

 by cutting down on the edges of the lumber. This machine appears to have 

 the combined effectiveness of two or more of the ordinary planing machines. 

 It turns out superior work. Price $1000. 



Gray and Wood's Planing Machine is a simple-looking affair, operates very 

 easily, and does superior work. The cutters are long straight edges attached 

 to a rapidly revolving shaft. Planes 25 feet per minute ; requires from one 

 to four horse power, according to stuff; can be used for cornice-sticking and 

 all other kinds of work. The cutters are arranged above the board, which is 

 placed on a traveling carriage like Daniel's machine. Price of a machine 

 capable of planing boards 8 feet long, 20 inches wide, only $210. 



Gear's Carving Machine. This improvement is intended for use in the pro- 

 duction of ornamental carved work for furniture, etc. The stuff is first cut out 

 into the desired outline form by means of a common scroll saw, and then 

 brought to the machine to be finished up. The apparatus consists of a com- 

 mon table, up through the top of which two or more cutter heads project. 

 The sides and edges of the stuff are worked and finished smoothly by being 

 brought in contact with the cutters, which revolve 4000 times in a minute. 

 One of these machines, we were informed, will save the labor of 30 or 40 men* 

 Price $300. By changing the form of the cutters, the design of the carving 

 is also changed. 



Lever Plane. An improved joiner's plane has been recently patented by 

 "W. S. Luffborough, of Rochester, N. Y., the principal features of which consist 

 first in the employment of cast-iron instead of wood to form the main body 

 of the tool^ and second in a novel arrangement for securing and adjusting the 

 iron or casting portion. This plane, which is designed to take the place of 

 those ordinarily employed by carpenters, joiners, ship-wrights, etc., is of about 

 the same weight, but much thinner than those now in use, and the hand of 

 the workman is consequently brought down to a position much nearer in line 

 with the resistance. This advantage, although reckoned by some experienced 

 workmen to be of considerable importance, is trifling in comparison with the 

 facility of adapting the plane to all kinds of wood. By the aid of two thumb- 

 screws acting upon a small lever, the iron is readily loosened or secured in 

 any required position. Thus, the iron may be much inclined for planing soft 

 and clear stuff, or set in a position much nearer the perpendicular when to be 

 used on hard and cross-grained material. One tool may thus be made to 

 serve in some degree the same purposes as a whole set on the present plan. 



Burley's Dovetailing Machine. A most ingenious machine for dovetailing 

 has recently been invented and patented by Mr. Burley, of Boston. The 

 main, features of the machine are a platform upon which a slicling-table rests,
