In orderto t operate easily in this position, the diameter :of vthe passage 16 should be somewhat 'I largerthan that ofthe passage through the .l tube 'to permit the incoming ink to exert A a pressure on the face of the valve'S which will assist in opening same, since the fric- .tion of the ink in passing through said tube 'serves to act as a pull to swing the valve open. .'Qlhe'l n may also be easily filled by holding it sidewise, the incoming ink lpassingpartly through the valve and partly through 'the tube, and the Ivalve swinging shut .on the in-stroke of the piston, the ink being-,formed against the back of the valve and closing same,"and the air being expelled `through the.tubeA to the atmosphere, or it may be filled with lthe top side up, the valve being open-by gravity permitting the ink to Yf lovw into the reservoir on the out stroke of' the piston, and on the in stroke thereof, the ink will be forced aga-inst the back yof the valveand swing it c osed, since the ink in the tube serves toclse this exit for the moment and the force of the ink is placed on the back of the valve to close same.

Anyother form-of pump may be lused if preferred to the form shown, .without departing from the broad features of novelty set forth.

It will be notedithat there are no springs or parts likely to be deranged in this oo nstruction and that the construction permits of a large supply of ink in the reservoir and 'easy filling means.
