7 Specification of Letters Patent.
Application filed October 30, 1917. Serial No. 199,250.
To all cchom it may concern:
Be it known that I, FRANK R. PERRY, a citizen of the United? States," residing at Chicago, in the county of 'Cook and State Jof Illinois, have invented certain new and useful Improvements in Automatic Controls for Vacuum-Pumps or the like, of
7 which the following is a description.
My invention belongs to that general class of devices known as automatic controls for vacuum pumpsand relates par- 7 ticularly to an apparatus adapted to be used in connection with thepumping' or causing afflow of a liquid or fluidby means of a vacuum. It is customary in the case of combustion engines where the fuel tank is below'the carburetor so that the fuel will not flow by virtue of gravity to the carbureter, to provide means for producing a How of the fuel. In some cases this is done in what is known. as the pressure feed, and more'commonly it is done by employing what is known as the vacuum feed system.
In the latter system the fuel is drawn by means of a vacuum into an auxiliary tank and'fed by gravity to the carbureter. A vacuum is produced in the system by means of a vacuum, pump or by tapping on to the manifold or to one of the cylinders. My apparatus particularly relates to a simple mechanism for periodically breaking or controlling. the vacuum so that the pumping is intermittent and not continuous. The invention has among its objects the production of: an apparatus of the kind described that is simple, compact, durable, eiiicient and V satisfactory. for use wherever found applicable. It has especially as an object the production of adevice of the kind described that does not require a float or nu merous springs, levers and the like necessitating consequent fine ad ustments. It also has as an object the production of a device that will not become inoperative in case allf ofthe fuel is pumped out of the main tank and which, does not at any time require priming. I Many other objects and advantages will be obvious to those skilled in the art from the disclosure'hereingiven.
To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and describedand more particularly pointed out in the claims.
' 5 In the drawings, wherein like reference characters indicate like or corresponding parts, 7 Figure 1 is a sectional view through my improved device; and V Fig. 2 is a cross sectional view taken substantially on line 22 of Fig. 1.
Referring to the drawings, 1 represents a casing of suitable size, shape and material which is preferably flanged at 2 about the top. .Arranged within the casing 1 is a shell 3 also of suitable size, shape and material formed with a bottom and also preferably flanged about the top at 41. A closure 5 is provided and the parts 1, 3 and 5 secured together by bolts 6 or equivalent means for the purpose, suitable packing or gaskets, however, being arranged between the flanges2 and 1 and closure 5 so as to provide a tight fit. The parts'l and 2 form substantially chambers A (vacuum chamberland B' (fluid chamber). Asshown, I provide a part 7 having the branch pipes 8 and 9, the same being constructed so that the same communicatewith the chamber 13. One part Sis arranged to be connected to a pipe 10 and the other to a pipe '11, the pipes being connected one to a vacuum pump or the equivalent and the other to a vacuum tank or auxiliary receptacle as it may be termed for the-storing of a supply of fuel orthe like.
As most clearly shown in Fig. 1, the chambers A and C are connected by an top of the cup shaped part 16 andthe bottom of shell 3, which is substantially the top of chamber A. The cup'shaped shell 16, constituting a chamber 0, is provided with a pipe 1920, the same constituting a siphon pipe with the end 19 below the end 20. I prefer to provide a pocket at the ends of pipe 20 by forming, the bottom of 16 as most clearly shown in Fig. 1,,so that the end of pipe 20 projects below the bottom of theshell 16. I also provide a pipe 22 extending from the bottom of the chamber A up into the chamber B, the upper end 23 being bent Patented Mar. 11, 1919.
' NITE STATES PATENT F I V B will also maintain valve 15 closed.
stantially below the bottom of the chamber A. Chamber A is provided with a vent opening 25 through which air may enter or be discharged from the chamber. n
I' consider it unnecessary to show or describe in detail the auxiliary receptacle with which my apparatus is connected as this may be of any desired construction. I might say, however, that I prefer to maketlie samesubstantially similar to my apparatus shown in Fig. 1, except that the piping 19-20 and 22'23, as well as the cup shaped shell 16 are omitted. Also, the chamber corresponding tochamber A is provided with a discharge outlet fromwhich a pipe extends to the carbureter. The construction will be obvious. The upper'end can be connected with the-main gas tank and with one of the pipes 9 or 8 of the apparatus shown in Fig: 1. a
The operation of the apparatus shown herein may be briefly described as follows The'desired amount of glycerin, lubricating oil'or the equivalent is placed in my device as shown in Fig. 1, so that the same if 0011- finedin the chamber C or container of the part 16 would come substantially to the level indicated by the dotted line L. Assuming that the same is originally poured in chamber B, it will flow through'the opening 12 .past' valve 15 and into container 16 until it' reaches the bend in pipe l920, through which it will siphon over into chamber A. If a vacuum is now produced in chamber B, for example by, connecting pipe 10 to a vacuumpump or to the engine manr 7 fold, the oil or fluid in chamber A will be drawn up through pipe 22 and discharged into chamber B, but the vacuum in chamber The lower end ofipipe 22 being in the fluid, the
'same forms a seal about the end of the pipe so that the airentering vent 25 cannot pass up'pipe 22 into chamber B- until all of the fluidin the chamber has been drawn into chamber B, after which air will enter chamber B through pipe 22 and the vacuum will be" broken. While there is a vacuum in chamber B there is likewise a vacuum in is again produced in chamber B, The operations described continue, the fuel being intermittently drawn into the auxiliary fuel tankto be discharged into the carbureter.
As soon 1 as-thesame is siphoned into chamber A the lowerend of pipe 22 is sealed and a vacuum Havin thus described my invention, it is obvious that various immaterial modifications may be Ima'de in the same without departing froni the spirit of my invention; hence l-do not'wish-tobe understood as limiting myself to the exact form, construction, arrangements and combination of parts herein shown and described or" uses men:
