JS'^o. 1659. — Count er-tioist Speeder. 

 Jesse Whitehead, Manchester, Va. Well adapted for coarse work 

 more especially, will do good work, and will no doubt save labor 

 and occupy less room. [.2 silver medal awarded. 



JVo. 1441 — Burring Machine, for Cleaning icool previous to its 



entering the cards. 

 Calvin L. Goddard, 3 Bowling Green, a useful machine, and pro- 

 bably the best thing for the purpose intended now in use. 



[.i gold medal awarded. 

 J\^os. 239, 109 and 1447—3 Knitting Machines. 

 J. Jackson, 32 Beekman-street. Designed and used with very 

 great success for knitting not only plain web, but common stock- 

 ings, socks, &c., without seam; they perform all the operations 

 of narrowing, widening, heeling and toeing off, indeed turning 

 off the stocking entirely finished, as perfect as when done by 

 hand, and at the rate of some fifty pairs per day when driven by 

 power, and requiring but one girl to tend some six machines. We 

 look upon this machine as one of remarkable labor saving, and so far 

 as we can learn, it has no parallel in its line. 



\^A gold medal aioarded. 

 JVo. 584 — Anti-Choking Ship Pump. 

 F. Ransom, Brookl}Ti, L. I. Marine disasters from the choking 

 of ships' pumps ai-e too frequent to permit us to pass such an in- 

 vention as this lightly by. The safety features of this pump are 

 several; the vein pipe is a straight open tube from the bottom of 

 the hold up to and above tlie deck, so that each substance that 

 enters the lower end of the pipe is brought upon deck and is there 

 passed through a strainer before going to the valves; this strainer 

 acting as a guard to the piston and valves, and the foreign sub- 

 stance being easily removed without any interference with any 

 part of the working arrangement of the punch. Four working 

 cylinders (all above deck) being made to act on the one suction 

 pipe insures a constant ascending volume of water, and by a very 

 simple device, a perfect vaccuum is obtained; direct access from 

 on deck can be had to tlie suction pipe, and should an obstruction 

 take place, the obstructing body can be removed without the inter- 

 ference with any other portion of the pump, and while the pump 

 is in operation. The valves are simple, easily renewed, and ac- 

 cessible without removing the cylinder or any of the pipes, the 

 joints are all so arranged as to be water packed, or prevented from 

 admitting air; a simple little device is attached which insures a
