DISPENSING PUMP- .c
r Appnmmon fied February 28,1924. serial No. 695,640.
The device isdesignedto permit a free` and uninterrupted discharge from' the nozzle immediately upon operating the pump while constantly retaining a full head of oil on display in the glass column, Vand as con.-
structed the device also stops the flow. of.
oil instantly without drip at the discharge mouth of thev nozzle when pumpin'goperations cease.
ln the accompanying drawings, Fig. 1 is a side View of a dispensing pump embodying my improvement. Fig. 2 is an enlarged sectionalv view ot ythe nozzley and oil f display coluinnor the pump. Fig. 3 is a. horizontal section on line-3O-3 of Fig. 2.
The inventionrcomprises a nozzle 2 having a tapped intake 3 adapted to be yscrewed upon the discharge pipe 4 of a vmeasuring and dispensing pump of any suitabletype or kind. In the present instance the lpump contains a valved'piston 6 which is'reciprocated in a well -knownvway by operating a crank handle 7 The oil is drawn trom a container 8 into the barrel orvcylinder of the pump uponfthe upward stroke 'of the piston while the oil above the piston' is being discharged, and a check valve 9 at the bottom of the pump prevents the oil from returning into container 8 upon the downward stroke of piston 6. As a result the pump head 10 and its discharge pipe 4and nozzle 2 are always full of oil., and an additional quantity a glass tube 11 attached to and forming a display column above the nozzle in line with its vertical discharge spout 12. This spout is open atits bottom and'in constant open communication with tube 11 and the discharge side of the pump as indicated in Fig. 2, where it seemingly appears that the oil within the column would be drained completely from the column by gravity upon a relates to an improvement of oil is also maintained iny .cessation of pumping operations. However y this is not the result in practice, the present 1 device being particularly constructedV to utilize a small degree of vacuum within the column andthe atmospheric pressure outside to hold the oil. in suspensionsubstantially the full height ofthe column when the pump is inactive. Thus, nozzle 2 embodies a horizontal wall 13 having separate sets of relatively small intake and outlet . openings 14 and 15, respectively, ofdilerent-diam'- eters. A division wall 16 within nozzle 3 separates the intake side of the nozzle `from the discharge side which is formed with a reduced extension into which a` straight piece of pipev otsmall diameter is' tightly fittedl to provide a small discharge spout 12. The
relative areas ofthe intakejand outlet openings, v 14 and 15, respectively, determine whether the-column will" remain fullof oill when the pump is inactive, 'and leakage and drip isalsocontrolled thereby.k The vsize of the intake openings' 14 is also a factor -in effecting the proper rate of flow of the incoming stream lrelatively to the outflow through the smaller outlet openings 15, the
diameter of the intake openings 14 prefer-l rably being such 'i that the incoming oil will be .jetted with considerable. velocity into the column of oil within the glass tube Vsothat f visible agitation yof the oil occurs in, filling the column initially and in subsequent dispensing operations when 'the column is full vor nearly full. The smaller outlet openings '15 restrict the outow of oil from the glass tube 4but a rapid luniform `uninterrupted stream of oil is discharged at the ,small spout 12 while the pump is'being operated to l jet oil into the column, andv inthis proceeding the oil llevel is higher on the intakeside of the column than on the outlet side as illus-v trated in Fig. 2. Then pumping and jetting ceases the oil iow from the dischargespoutV stops instantly and the column of oil within the glass tube remains atfthe same height at about the level shown inthe drawings and no leakage or drip occurs notwithstanding the outlets are open.
Satisfactory results as above stated may be obtained ,with a heavy oil by using a single inlet port 14 approximately nine thirtyseconds in diameter, or several smaller openings aggregating that area, providing the outlet port or ports 15 are about twenty percent smaller. A series o small ports may be usedyto increase thevolume of discharge, but by making the ports small one or more tine streams of yoil may be jetted into the column With-,sufficient .velocity to agitate theY body of a heavy l-ubricatingoilso -that a largev percentage ot the air above the oilin the glass tube Will be mixed with and absorbed by the oil jetted into `vthe .coluinnand conveyed out of the tube and the volume of compressed air in the tube reduced to a minimum, especially Kin filling the tube in ,the
