 be thereby saved. 



Fifth. It appears to be easily adjusted to produce nails of any 

 desired form or proportions. 



The above are the principal advantages claimed for the appa- 

 ratus, as exhibited, and the committee see no reason to doubt that 

 they may be realized in practice; though, before giving it an 

 unqualified recommendation, tliey would prefer to have the evi- 

 dence which would be alfbrded by a more extensive trial in a 

 regular manufactory.

Description of the above Machine. 



A is the frame, which is of great strength, and mounted on four 

 rollers, so that it can be moved from place to place, or to different 

 positions in the workshop; B is the driving belt, communicating 

 power from the main shaft to the band and fly-wheel C; D is an 

 ordinary nail machine, having on its shaft an eccentric, grooved, 

 which receives a pin or roller projecting at right angles from a 

 bar, G, and by the motion of this pin in the eccentric, it causes 

 the bar to move up and down while the pin slides in the guides, 

 F. The bar, G, is connected by a screw with the piece, H, which 

 is free to move in guides on the plate, I, that can be adjusted to 

 any position on the table, J, screwed or otherwise attached at any 

 suitable angle to the standards, K, which rise from the frame of 

 the nail machine, A, at suitable distance from the dies. To H, 

 two bars, 0, are attached, bearing or holding at their extremity a 

 hollow guard, P, through which the iron to be cut projects. This 

 piece of plate iron is seen at R, held by the j^incers or teeth, Q, 

 which are attached to a rod that is rigidly connected with the 

 cam, L, in H, and also connected with the screw, M.
