Portable Steam-sawing Machine. 



One of the most novel and ingenious machines for sawing trees and timber has been 

 recently invented by Mr. S. R. Wilmot, of Nei» fork City. It is nothing more nor less than 

 a steam hand-saw. The handle is made round and hollow, and has a steam piston fitted 

 within, to which the saw is fastened. Steam is admitted at the back end of the handle, 

 through a flexible pipe made of canvas or rubber. The rapidity with which the saw is made 

 to move back and forth is astonishing. The principal object of this invention is to cut down 

 trees in forests or swamps, or wherever the nature of the ground is such that it i- desirable 

 to have a very light but effective cutting apparatus. The operator takes up the snv by the 

 handle, which is only two or three inches in diameter, holds it against the base of the tree, 

 and lets on the steam. The next thing seen by the spectator is the tree in the act of falling, 

 so quickly has it been cut through. Where the trees are very large, a light frame is employed, 

 in which the steam-saw is held when at work. The extreme portability of this apparatus 

 enables the operator to cut up a tree into logs, after it is felled, with the utmost facility. 

 The boiler is of sheet iron, and, though amply strong, is easily carried about by one man. 

 The flexible steam-pipe permits the saw to be taken from tree to tree, in any direction around 

 the boiler; the only limit of the distance being the length of the hose. This apparatus, we 

 are informed, has been thoroughly tested, and found to operate with the most practical suc- 

 cess. — Scientific American. 



In an invention of Pliny Young, of Milwaukie, Wisconsin, recently patented, the saw is 

 made to cut while the carriage is moving either way. The whole apparatus or device is also 

 self-acting, the log or timber being set to the saw, and the motion of the carriage reversed 

 without any extraneous aid or power being applied. The log or timber may also be set at 

 any required distance towards the saw, so as to saw stuff of any required thickness by merely 

 altering the position of the slides. 



Improved Butter-worker. 



The accompanying engraving represents a section of an improved butter-worker, recently 

 invented and patented by Ezekiel Gore, of Bennington, Vermont. 



The nature of this invention consists in the employment of an endless revolving sack or bag 

 for containing and confining the butter, and conveying it to and between two fluted or work- 

 ing rollers, and through the water in the tub or box as fast as the rollers operate upon it, 

 until it is thoroughly worked, washed, and seasoned.

 supports the bearing! of the rollers 1? C D. The box A is made in two sections, BO thai its 



tipper part may be removed, and also the rollers and sack, when it Is desired to oleanse the 



lower part. The roller B is made perfectly smooth, and has it- bearings at the back end 

 of the machine, and the roller C is Anted, as shown, and has Its bearings near the front end 

 of the machine. On and around these rollers the sack F is arranged as represented. The 

 roller D is fluted similar to C, and operates in concert with it, but is prevented from touch- 

 ing it by the sack, which is placed and revolves between it, as illustrated.
