PURVEYING DEVICE.
To all whom it may concern.'
Be it known that I, GILBERT N. WoonwARn, a citizen of the United States, residing at Portland, county of Multnomah, State of Oregon, have invented certain new and useful Improvements in Purveying Devices, of which the followingis a specification.
My invention relates to purveying devices in general, and particularly to that class of such devices as are used for the automatic purveying of liquids, such as gasolene at automobile filling stations, and the like.
The objects of my invention are to provide' a purveying device that will accurately measure the liquid delivered therefrom; that may be adjusted and sealed; that will measure the liquid dispensed withinsight of the purchaser; and thatY will not be disturbed in the accuracy of its functions by dirt, sediment or. scale in the liquid;
I accomplish the abovevobjects, and other desirable results, by means of the construction illustrated in ing, which therefore becomes a part of this application for Letters Patent, and which shows a side elevation of my devicewith parts broken away to best illustrate the construction and operation.
In general my device consists of a pair of reservoirs 1, of glass or other suitable maliquid is measured, and into which the liquid is delivered through a supply pipe 2, and means whereby one of said reservoirs is delivering measured liquid while the other is being filled, said means being operated by the liquid within the container being filled.
As a means of distributing the liquid I provide an ordinary slide valve 3 operating over ports 4 and 5, the said ports each connecting with its respective reservoir by means of respective passage-ways 8, said passage-ways each connecting with a delivery pipe 6 wherein is a check valve 7.
The liquid enters valve chamber 9 through supply pipe 2, being delivered thereto by a suitable pump, or by gravity from an over head tank, or in any other suitable and convenient manner, and passes therefrom by means of one of ports 4 and corresponding passage-way 8 to one of the reservoirs 1, that upon the right in the drawing.
the accompanying draw-4,
The oat valve 10 is raised by the entering liquid as far as the cage 11 will permit. The liquid then fills the reservoir 1 and finally overflows therefrom throughvalve chamber 12 and pipe 13 leading therefrom. Pipe 13 connects with a cylinder 16 at that end of valve chamber 9 opposite the reservoir 1 with which said pipe 13 is connected, thus conveying liquid from said reservoir 1 to said cylinder 16 to act as a fluid pressure agent for moving valve 3 by means of piston is connected to valve 3. v A drainage-pipe 17 is supplied for draining cylinders 16 which pipe leads back to the supply tank or pump, as convenient.
When theV liquidr in reservoir 1 (right hand) has overflowed into the pipe 13. connected thereto, pistons 14 will be forced to the right and thus move valve 3 to the right so as toopen left hand port 4 to valve chamber 9 and connect right hand port 4 to port 5.
Left hand reservoir 1 will then fill with liquid, while right hand reservoir 1 will discharge its contained liquid by gravity into pipe 6 by means of passage-way 8 and ports 4 and 5.
When left hand reservoir 1 is filled the reverse action will take place, the reservoirs will, therefore, obviously automatically alternately fill and dispense with the liquid being purveyed, as long as pressure is maintained upon the liquid in supply pipe 2.
' As a means of accurately measuring the liquid in each reservoir and adjusting the same, I provide a piston 18 disposed within a tube 19 integral with and depending from reservoir head 20. 1
Said piston 18 is operated and adjusted vertically by means of a screw 21 threaded i into head 20 and attached to piston 18, so
that the amount of liquid contained within reservoir 1 may be decreased or increased by respectively lowering or raising piston 18.
A cap 22 covers screw 21 and may be sealed to head 20 by means of an ordinary wire seal, as shown at 23.
25 adapted' tov rais'e'and cl'ose'the enduit-pipeA the reservoir 24 when the liquid has filled and entered the chamber l2, thus then directing all the liquid under pressure into pipe 13 and thereby into cylinder 16, .for the purpose of moving valve 3.
Float valves l0 are for the purpose of closing before the liquid is entirely expelled and thus preventing' the escapeof the air Withinthe two reservoirs and their connecting pipe 24. .A A
VThe air pressure may be made as great Vas desired by introducing air in any convenient manner, suitably by opening the air cock of the'pump supplying the liquid toV pipe 2 until sufficient pressure is obtained.
A safety valve 25a is installed in vpipe 24. My invention may be made of any size and constructed of any materials deemed convenient and suitable for .a device of this character, and While I have illustrated and described a form of construction and arf rangement of parts found desirable in materializing my invention, I Wish to include in this application for Letters Patent all mechanical equivalents and substitutes that may fairly be considered 'to :come Within the scope and purview of my invention as defined in the appended claim. Having disclosed my invention so that others skilled in the art may be ena'bled to Copies of this lpatent may be obtained for `ve poents each, 'by addressing `the Y Washington,v ILUA ing-a."pair of reservoirs; a valve intermedi- .ate said reservoirs-s; .a
discharge pipe; a piston connected to said valve and operating Within ya cylinder; a body connecting said reservoirs and having therein suitable ports coacting with said valve for the purpose of simultaneously ,connecting one of said reservoirs With the source of supply of said liquid and the other of Said reservoirs with said discharge pipe; a .valve lchamber upon veach of said reServorSo,-said valve chambersbeing comiected ,t0 Asaid cylinder `upon 'opposite sides-of said piston; an air pipe connecting Said valve chambers.; aljloat valve Within each of said valve chambers adapted toelose said air pipe; an expansi'ble and contractible member Within each of said reservoirs; and lfloat Valves at the points Whereat said reservoirs connect With ,the port Within said bod Iii Witness Ywhereof I claim the foregoing to be my own I hereunto ,allix my signature in 'the presence of tivo subscribing Witnesses, at Portland, county of Multnomah, State of Oregon, this lthvday u.ofJuly 1917.
