My invention consists of an improvement a balanced multiple ram accumulator and intensiflea tor use in connection with any utilizing subject to the generated pressure thereof.
The objects ofthe invention are to provide in such accumulator, a main supporting base, a plurality of cylinders and rams in spaced apart location, connecting. same with the base and supasuperi-mposedrising and falling weight of material substance, adapted to be elevated and lowered, to perform its intended functions. Ordinarily, suchdevieeshave consisted of a centralr supporting and elevating ram of the plunger type, asurrounding laterally extending weight-i or weights, bracing means and connections,- and intendedto effect generally similar purposes.- y
In invention, the base is of ample area, substantially co-extensive with the area of the weight members, the plunger cylinders and rams of any suitable number being located laterally beyond the center, and cooperating with the weightlin series of equivalent impulses and resulting lowering, for amplified-application of liftand lowering movements, as shall. be more fully hereinafter described;
"In the drawings, illustrating certain preferred embodii'nents of the invention:
, Fig. '1 is a one half plan view of an accumulater when provided; with aseries of three annulhrly located. plunger cylinders and rams;
Fig. 2 is a half elevation and cross sectional view, on the line II'IE- of Fig. 1;
Fig. 3 is a cross sectional view on the line Fig. 4 is a plan view of an installation utilizing a similar plurality of suchmembers, as four, for reception of the superimposed weights, and providedi with localized valves;
Rig: 5*.is a front elevation thereof, complete;
, is aview of one of the-intensifier valves;
Fig. 7 is a sectional detail view of one form of bufllng support for the platform.
Referring to Figs. 1 and 2, the base 2, which may be circular or otherwise, of heavy cast or welded metal, or pipe, is provided with an annular circulation space 3 having connection as at 4 with the input and outflow piping or the like, for introduction of fluid under pressure, for elevation lifting and outflow therefrom respectively, for lowering, and application to any utilizing element, generally similar as to present practice in similar operations.
At preferably equally spaced outer annular locations, are supporting ram bases 5, secured to 5 Claims. (cuss-30) 7 the upper surface of base 2 as by bolts 6:, with which are connected in any suitable manner as by threads "I, the upwardly extendin tubular open end conduit rammembers a.
These communicate with annular opening 3 by means of a conforming opening a at lo-, cation of the base, whereby circulatiomis pro-- vided between annular opening ,3,- -arrd,the several tubular ram members; 8, simultaneously throughout the series, dependent onthe infiow or outflow of the fluid medium The weight supporting platform to, of ample dimensions and thickness for stability, and sup,- port of the superimposed weight member or meme ,bers H, is provided at- .-locations corresponding to the spacing of the tubular rain members a, with a corresponding series of cooperating cylinders l2, closely and slidably engaging the corn tinuously hollow ram members,
Su-ch cylinders, of ample dimensions and strength, are telescopically mounted upon? and around the open end conduit rams 8, and are preferably rounded and positively closed.- attheir outer ends, as at t3; They are firmly connected with base H): by flangesl4 and bolts l5 and-are preferably provided with stufiing box elements l6, packing I1, and if desired,- supplemental bearing rings 18, as shown. They constitute together the elevating and lowering means of the machine. By rounding the upper closing terminals 13 of cylinders I2, placement of the weight members M is facilitated.- a
As illustrated in 3,. the cylinders T2 to.-
gether with the ram conduits and their bases, are preferably removable radially o'fiplatfornilll, by means of separable-holding caps 19" insded in suitably spaced radially di'spos'ed' clef in the main base platform, fll, andheld'bybolts '20? .or other suitable means; The weights T I resting uponpiaftrdrm 'IU riiay be of" any suitable material, as concrete, series of metal plates, or the like, laid continuously upwardly, and so apertured laterally, as to permit of placement and removal of the ram conduits 8 and cylinders l2, when desired. For such operation, the platform and its gravitating portions H may be temporarily supported by suitable means above the base 2.
Otherwise, the cylinders may be permanently installed, extending through the series of weight members, for certain types of the apparatus where removal is not desired. However, facility for such separation is of considerable advantage in disassembling the machine for repair or renewai, and is of value in providing safety and. economy, as will be readily understood.
In any such operation, the platform and its weights, may be jacked up and temporarily supported by any suitable means, as built up framing supports, or may rest on bufier springs 23 located between the rams, and between the base plate, as in Fig. 7.
Figs. 4 and 5 show a similar construction in which four equally spaced cylinders and rams, of the same general character as above described, are utilized, mounted on a similar hollow circulating base. Such construction is also provided with similar upwardly extending circulating tubular ram members 8, and cylinders l2, and otherwise, except as to number, are substantially the same in construction and operation as those above described as to Figs. 1 and 2.
The same general construction is illustrated as to the supporting platform [0, weights II together with intensifier valves 2| connected'with certain of the members 8 through base cavity 3, and-having a bleeder valve 22, for intensified application of pressure through rams 8, when desired, dependent on the conditions of desired pressure and varying operation of the entire machine.
Otherwise, the construction is generally the same, and operates in substantially the same manner as above described.
' With either form of construction as to location of the cooperating ram conduits and cylinders, the superimposed weight may be raised to the necessary extent by power pressure of the fluid into the interior of base 2, for lifting, with resulting utilization of the downward pressure for application as desired, the upward and downward movements being necessarily limited by the length of the cylinder and ram. It will be observed that the machine as thus constructed is always in'equilibrium and substantial balance; by reason of the plurality of rams and cylinders, the lifting power is amplified and equally applied at outwardly remote locations for perfect adjustment; the construction insures stability against any tendency to collapse or tilt under lateral strains; and the construction as a whole is in balanced equalization, very substantial and durable by creating an even wear on the rampacking, and capable of continuous accurate and reliable operation, in use.
