It Operates without re adjustment from 25 picks up to its high- 

 est speed. Those ibr thirty inch width run to tlie bes', advantage, 

 at from 180 to 200 picks per minute, and have been run experi- 

 mentally with perfect success at 35'), producing from one to four 

 yards per cut over what is usually obtained from same web. 



The cloth may be taken from the looms witliout stopping them. 

 The filling stop avoids atmospheric resistance ; there are no pick- 

 er strings, pickers, or picker spindles, and no breakage to cops 

 at the highest speed. There are no metallic connections in the 

 picking motions, and no liability to wear. These looms are con- 

 structed to stand in line both ways on the factory flo-.tr. 



The new centritiigal friction pulley combines the fast and loose 

 pulley without shifting the belt, and is constructed to produce 

 diiferent speeds without altering the belt or the speed of counter 

 pulley. There is no wear upon these friction pulleys, whether 

 running free, or driving the loom beyond that of a ccnnmon loose 

 pulley. [Jl silver medal awarded. 



Drop Press, 



Milo Peck, New Haven, Conn. Jl A are the standards or ways, 

 between which the drop E with its die attached, moves; B is the 

 bed or anvil, with the lower die secured in its place; C is the 

 frame of the raising machinery, (with one corner removed tO show 

 the spring catch U;) G is the lift crank; Fis a leather strap con- 

 necting the crank G by its pin with the drop E. The crank has 

 holes in it to insert the pin at different points from the centre, to 

 give a long or short stroke to the drop; is a double n-ank, to 

 one end of which is attached the dog L. There is an eccentric 

 guard ring, (not seen,) which raises the dog from the teeth of the 

 ratchet, when the drop is at its highest point, at the same time 

 that the other end of the crank strikes the catch U, (\vh"ch is 

 connected by the rod J, with the treadle T",) and is locked firmly 

 in its place, as shown. While the ratchet with its hub 7?, upon 

 which is keyed the pulley //, revolves loosely U].c:i thj crank 

 shaft. When the workman presses upon the treadle 7', tlio catch 

 l/is depressed, the lock crank is released and the drop tails, car- 

 rying around the shaft, with its crank, &c., until the drop is at 

 its lowest point, when the dog L leaves the guard ring and is 

 pressed into the teeth of the ratchet wheel by spring .A^, and is 

 carried around, raising the drop to its higl est point, when it is 

 again raised from the ratchet, (which continues to revolve,) and 

 the crank is locked in its place, suspending the drop E by the 

 strap F, to be again tri[)ped.
