This invention relatesy to liquid-handling apparatus, and with lregard to certain more specific features, to a visible hand-measuring pump for oil and the likef Among the several objects of the invention may be noted the provision of asimple and compact structure permitting the vclistomer to view the goodsabout to. becdelivered to him; the provision of an ineXpensive and durable arrangement of concentric opaque and translucent cylinders, between which the liquid passes on. its way .to the dispensing' V orifice andthe provision ofimproved means for displaying thetrue color of the liquid that is being dispensed. Other objects will bein part obviousand 1n part pointed out hereinafter. u v
The invention accordingly consists ofthe elements andlcombinations of elements, features of construction, and arrangement of parts which will be exemplifiedA in the structure hereinafter described and the. scope of the application ofwhich willbeindicated in the following claims. x
In the accompanying Y is shown oneof various. possible embodif ments ofthe invention,
yFig. 1 is a vertical section-onthe line y A v ished nickelsurface.V The liquid, com-ing up Fig, 2.is a top-.plan view; 1
Fig. 3 is a horizontal section on z the line 3-3ofFig.1; f v 'i Fig. 4 is a front elevation; j 4 y ,Y -Fig. 5 is a horizontalsection onthe line 5-5 of Fig.,4; and Fig. 6 is a plan view of a libre gasket. Similar'reference characters indicate corresponding parts throughout they severah views of the drawings.
Referring now more particularly to Figs. Y
1 and 2 of the accompanying drawings, there is illustrated a pump comprising a polished metal cylinder 1 preferably of brass, within which reciprocates a piston 3 fixed to the rack 5 which meshes with 'a pinion 7 driven by a hand crank '9. The downward stroke of the `piston is limited by the` shoulder or abutment 11 of the frame 13. The upward stroke of the piston is adjustably limited by the set screw 15 mounted in a cap 17 threaded upon the tube 19 that houses the rack 5. The set screw is locked in position by a' lock nut 21. Y
The entire pump is adapted to be mount# drawings, in which Y.
ed upona threaded pipef"(not shown) eX- Ytending upwardly from a source of supply of liquid, such as an oil tank. The threaded pipe fits into the internally threaded projection 23 at the lower end of the pump. c
Rotation of the handfcrank 9 in a clock- VV,wise direction (Fig. 1) raises the rackV and piston vand-causes liquid to be drawn from the source ofsupply (not shown) connected to the threaded projection l23, upwardly through theVV passage 25, past the ball check 27 into the chamber 29. As the piston rises, oil is drawn into the chamber 29 andordinarily fills the space 31 beneath the piston.
This may be termed the filling stroke of the piston.
` On the downward or dispensing stroke of the piston thejliquid passes from thespace 31and chamber29 throughlthe second .ball check 33 andv thence upwardlythrough" a plurality of holes 37 (Figs. 3 and V6) in-a fibrewasher or gasket 39 (Fig. 6). lThe liquid is then forced upwardly through the) annular space 41 between the brass cylinderV 1 and a glass cylinder' 43 mounted outside the brass cylinder and concentrically dis-v posed with relation to the latter.V Y l The brass 'cylinderpreferably has a polbetweenithebrass and glass'cylinder, is visible tothe customer. The metal cylinder reflects the light incident upon it, so that the liquid is given substantially its natural color. The customer is thus able to judge accurately the nature and quality of the liquid that is being delivered tohim. This is particularly true because the radial distance between the two cylinders Vis small enough (preferably about one-'fourth inch) so that plenty of light'passes through the liquid to the metal cylinder and is there reflected.
When the liquid reaches the upper Aend of the glass cylinder it passes again through V a plurality of holes 45 (Fig. 5) in a fibre Vgasket 47. The gasket resembles the gasket to the piston 3 by a locknut 53 (Fig. 1).
The piston has a peripheral slot for receiving a'lielicalf'ispringf V which vsenves to press outwardly'against themetahcylin-4 ,der l a plunger leather 57. A nut 59 -thiead- :ed onVV the lower'pontion ofthe'E piston servesy to retainv` the," plungerleather: against' dis-y placement with respect vto the piston` The brass and glass cylinders 1, 43, are
mounted in concentric slots in the underface` of the top casting 61 and in similar slots in the upper face of thebcttoni castingl The tcp and-bottomcastings 61,113, are 5 'Y heldtogether by three tension rods GSffQFig.
The two Valves each comp-rise a Atube 71 threaded at eacliend andhaving wrench' slots at itsupper end into the lower c'astin'grl'. The upper endfoflfeachY tube is the seat. for
i the valve ball'l- Each tube has a cap 7.5
threaded on its lower end.
` Y At the end of the pinion shaft 77 opposite the handle 9 isa counter 791 (Figs. 2' and" 5) driven through a ratehetf (not shown-, so that the counter' 'is actuated'only upon'the down:l strokeof 'the piston.
As soonv as some'liquid has been dispensed YYfrom,Y the pump,V the annular space between rtheii-ietal andfglass cylinders remains full lower side of the intake' check Valve 27' and* ofjli'opiidl andi thus displays to customers the quality off liquid that' the pump` delivers. n One of' th e -.th1reey tension 'reds 631 (Fig.4 1') isutilizedas a passageway- 81 betweenr the the' upper side'of theV piston. This prevents the formation ofavacu'uin in the'space above the piston, andV carries away any-liquidwliich may leali pasttheplungen leather.
In view ofthe above, it is believed' that thevarious featuresof'this invention. will Y be clear without further elaboration, and it Y will be seen1 that with the apparatusherein described, the several objects of" the inven- Leitrim tion` are achieved'andI other advantageous results attained. n
As many changes could be made in carrying:outfrthe''above` construction without' departingrfrom the: scope of the-invention, it is 'intentiediA thatallr-in'atten` contained in the above description or shown in the accompa-Y nying drawings shall be interpreted as illustrative and not in a limiting sense;V
