SPECIFICATION forming part of Letters Patent No. 487,531, d'ated December 6, 1892.
Application filed June 24, 1892. Serial No. 437,855. (No model.)
To all whom. it may concern,.-
Be it. known that I, KARL KIEFER, a kcitizen of Germany, residing at Cincinnati, in the countyof Hamilton and State of Ohio, have invented certain new and useful Improvements in Barrel-Fillers; and I do hereby declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the arttowhich it appertains to make and use the same.
My invention relates to apparatus for lilling barrels or similar liquid-receiving receptacles.
In carrying out my invention I construct the device so that the intlowing liquid requires no greater pressure than is employed with ordinary siphon hose and will not be eX- posed to outside atmosphere.
My invention further consists in means that when the filling reaches a certain elevation further inflow is automatically shut off and the state of the contents of the vessel will be indicated by an audible alarm, all as hereinafter fully described, illustrated in the drawings, and speciiically pointed out in the claims.
Referring to the accompanying drawings, wherein like letters and numerals of reference pointout similar parts on each view, Figure I is a vertical central section of` a filler embodying my invention in position for operation. Fig. II is an enlarged detail view, partly in section, of the valve-operating mechanism.
A is an outer funnel-shaped vessel or incasement, its lower end terminating with downwardly-extending tube A and an upwardly short tubular extension a', the end of which is outwardly threaded for reception of orificed cap A2, which has a lower circumferential flange a3, the inner face of which is threaded to take onto thread of tubular eX- tension a', as shown in Fig. I. The incasementA is preferably in two sections, the upper one forming a cover a, shown as connected by screw e, that can be removed in order to have access to the interior structural elements of the device.
Within the extension a', shown integral with the cover concentric therewith,is ashort tube forming valve-seat E, for a purpose presently set forth.
The cap A at its upper end is outwardly threaded to intermesh with threads of coupling o, to connect thereto supply-pipe K, which at its lower end has an overturned circumferential flange, whereby these coincident members of the device are hermetically connected.'
Y A threaded sleeve or any well-known coupling device may be employed without departing from the scopeand purview of my invention.
Within the vessel Aand its cover is an extending rib a4, which serves to strengthen the structure and furnish su pports for certain connections, as hereinafter specically pointed out.
B is an interior vessel, herein called a funnel, retained within incasement A and of dimensions that will enable it to move therein vertically without contact therewith. From the lower cent-er of funnel B there extends lower section of valve-tube D, which is continued upwardly vertically through central line of funnel up to and within valve-seat E. This tube near its upper end is divided diametrically by cross-tube G, within which lies horizontal toggle-joint L, above which tube D is continued to and within valve-seat E, as already set forth. At the center of the sloping bottom of funnel B the tube D branches inwardly, leaving aperture d', opening into said funnel, and from thence downwardly said tube is divided into two vertical sections O O. The stem of tube D, divided as set forth, passes within lower end of tube A of incasement A, but is of reduced diameter thereof, thereby leaving circumferential duct c, through which air will pass upwardly from the barrel R or other receptacle.
In practicing the invention I employ an outwardly-tapering bung or cork .l of yielding material having central bore, through which will pass tube A as illustrated in Fig. I, which is compressed tightly therein to secure hermetical closure at the inlet-point of vessel R.
Near its upper end tube D is provided with one or more apertures d for fluid-inlets. Its
Vupper terminal is supplied with cap C, which when brought downward will close said apertures and prevent passage of liuid from supply-pipe K, as will be readily understood.
L is a togglejoint consisting of two leverarms pivotally connected at their respective ICO outward ends to rib a4. The lever-arms at their opposite ends lie transversely within tube D, near its upper end. The outer end of each lever-arm has slot l), through which passes short pin M, the ends of which are held in place by uutsm m. Said pins M form fnlcra or a toggle-joint. Surrounding each sectional arm of the toggle-joint is a spiral spring S, which reaches from each pivoted end toward abutment s at each inner end of toggle-arms. The inner end of each lever-arm is finished with an apertu red disk, back of which is a block n, providing an abutment, which forms a bearing forinnerend of spiral spring S, the opposite end of which bears against a washer 3 or suitable shoulder of said leverarm. Each lever-arm has near its outer end a horizontal slot l), which serves for passage of end of pin M and also for movement of said arms when the springs are actuated.
H is an alarm-bell connected to the upper end of cover a, and ga striker, which is pivotally connected at its lower end to rib a4. The stem of the striker has inwardlyinclined branch arm 7L, and is held in position shown in Fig. I by spring 7c against detent fr', and by which, as will be readily understood, its vibration is limited when set in motion.
From the foregoing description, in connection with the drawings, the nature and practice of my invention will be readily comprehended by all familiar with the line of art to which it is allied.
Its operation may be thus briefly explained. The device adjusted, as illustrated in Fig. I, is inserted within bore of bung J and forced downwardly therein, so as to prevent any passage of air from or into receptacle R. A supply of fluid is then fed from supply-pipe K, which will pass through apertures d into tube D, iiowing through section O thereof into vessel R, and the displaced air will pass upwardly through section O and be ejected through aperture d into and within funnel B. At the Sametime a small quantity of theair will pass upwardly through circumferential space c, intervening' between tubes D and Ainside of incasement A between its interior surface and funnel B. lVhen, however, the liquid (illustrated in hatched lines) reaches an elevation up to the lower end of tube D, the passage of air through section O will be arrested and escape of air will be confined to passageway c, and as a matter of course the liquid will rise in said section O. Liquid will, however, continue to flow into the vessel A and its level will gradually rise until it reaches the lower end of air-duct c, when, as will be understood, the downward ow will be shut oft. As the liquid rises, as set forth, it will pass up tube D and some quantity will iow into the funnel B through aperture d', which, together with the quantity within said tube, will counterpoise tension of spring S on toggle-arms, and said arms will be turned down in position opposite to that shown in the drawings, forcing down the valve closing head of tube D into seat E, and at the same time the bottom of the funnel B will be brought against arm 7L of striker g, which will thereby strike an alarm on gong H. Thus an audible alarm will be given coincidently with rising of the liquid up to lower termination of valve-tube A. The small quantity of remaining liquid in the funnel and within spout of tube D will be discharged into vessel R as the device is withdrawn.
Having thus fully describedv my invention and the manner of its operation, what I claim, and desire to secure by Letters Patent of the United States of America, is
l. In a barrel-filling device, incasement A with lower extending integral tube A and upper tubular extension a', within which is concentric valveseat E, interior funnelshaped vessel B, the lower central point of which is continued downwardly, and valvepi pe D, said pipe being divided below vessel B into vertical sections O O', inserted within tube A', the upper end of one section having aperture d', opening into vessel B, said tube D passing upwardly into valve-seat E and having terminal closing-cap G, below which are fluid-inlet apertures CZ, substantially as described.
2. In a barrel-Iilling device, outer incasement A and vessel B, having sloping bottom inclosed within outer incasement and movable vertically therein, in combination with striker g of gong H, adjusted outside of incasement A, said striker at its lower end having in wardly-extending branch arm 7L and pivoted to rib a4, whereby as vessel B is moved downwardly it will be brought in contact with said arm and strike an audible alarm, as and for the purpose int-ended, substantially as described.
3. In a barrel-filling device, vertical tube D, having at its lower end section O', terminating at its upper end with opening d', communicatin g with interior of vessel B, above which said tube extends upwardly of uniform diameter, its upper end supplied with valve-cap C, adapted to close valveseat E, said tube near its upper end provided with transverse tube G, into which is seated inner ends of leverarms L of toggle-joint L, said ends carrying blocks 2, the opposite ends of said arms pivotally connected to rib a4 of incasement A and having end slots b, through which pass fulcrum-pins M, each of said lever-arms surrounded by spiral springs S, the ends of which bear, respectively, against block 2 and washer 3, substantially as described.
4. The within-described apparatus for filling barrels or like fluid-receptacles, consisting of incasement A, having lower tube A', and elastic oriced bung J, said incasement having at center of its upper covering upwardly-extending open-ended tube a and inner concentric valve-seat E, in combination with cap A2, having depending circumferential iiange internally screw-threaded to take onto threads at the upper end of tube a', in
combination with supply-pipe K and coupling o, substantially as described.
5. In a barrel-filling apparatus of the character described, supply-pipe K, coupled to cap A2, incasing-vessel A, valve-seat E, valve-tube D, provided near its upper end with Huid-inlet apertures CZ and end cap C, adapted to close said seat when the receiving-Vessel is filled to a predetermined elevation, and the valve-tube D, continued downwardly and midway of its length, connected to the lower central point of inner vessel B, below which it is divided into sections O O and loosely inserted within tube A of incasing-vessel A, leaving circumferential air-escape space intermediate of said tubes, all in combination with interior vessel B, whereby as fluid passes into the receiving-vessel air will pass upwardly through section O into and Within vessel B and when the contents of the vessel reach up to the lower end of valve-pipe D the liquid will rise in said section O and pass into and within vessel B, which will thereby gradually fall by gravity and aotuate springs of toggle-joint L, bring closing-head C Within valve-seat E, and shut off supply of duid, at the same time actuating striker g, whereby an audible alarm Will be sounded on gong II, as and for the purpose intended, substantially as described.
In testimony that I claim the invention above set forth I affix my signature in presence of two witnesses.
