Definitions

  • a clamp assembly is provided suitable for use with a two part pressure vessel, employing an integral bracket afiixed thereto.
  • the clamp is adapted to positively seat at the parting line between the two parts of such vessel.
  • the bracket structure includes two flat members disposed on top of one another with the upper member slidably connected to the lower member and the lower member affixed to the clamp.
  • top bracket member is provided with a flange which engages a band that is suitably fastened about the periphery of the top portion of the pressure vessel.
  • the present invention is directed to an apparatus for use in conjunction with a pressure vessel. More particularly, the present apparatus is directed to a clamp arrangement capable of positively sealing the upper and lower portions respectively of a pressure vessel.
  • a principal feature of the present invention contemplates a clamp assembly for securing the upper and lower portions of a pressure vessel including: a sectional closure means attached at several points to form a unitary structure, fastening means disposed at the open ends of said closure means adapted to adjustably fasten said closure means, a circular band concentric with respect to said closure means and in cooperative relationship therewith, fastening means associated with said circular band adapted to fixedly adjust said band with respect to said closure means, and bracket means integral with said closure means being provided with slidable means to enable said closure means a controlled amount of lateral movement.
  • the bracket means is afiixed to said closure means at a point about the periphery thereof, said bracket means including a top member and a bottom member, said bottom member being affixed to said closure means and said top member being slidably attached thereto, and additionally affixed to said circular band, and adjustable means disposed within said bracket means to control the length of travel of said top and bottom members with respect to one another.
  • a principal object of the present invention is to provide a clamping arrangement free from the defects of the prior art.
  • Another object of the present invention is to provide for a clamping arrangement adaptable for use with a pressure vessel having an upper and lower portion.
  • Still another object of the present invention is to provide a clamping arrangement adapted to be fixedly mounted on the periphery of said vessel to enable positive closure as between the upper and lower portions of such vessel.
  • Still another object of the present invention is to provide a clamping structure adapted to be positioned about the periphery of the point of contact as between the upper and lower portions of a pressure vessel, capable of being easily released to enable separation of the upper and lower portions of said vessel.
  • a further object of the present invention is to provide a clamping arrangement including an integral guide structure to enable the clamp to freely disengage the peripheral surfaces of the vessel while at the same time being retained in position on the head by a suitable circumferential band.
  • Still another object is to permit the whole clamping arrangement to be removed for cleaning or replacement if necessary at a minor expense.
  • FIG. 1 is a perspective view of the present invention affixed in the closed position to the pressure vessel assembly.
  • FIG. 2 is a perspective view of the clamp shown in FIG. 1 in the open position.
  • FIG. 3 is a partial section of a top view illustrating the bracket attachment to the clamp.
  • FIG. 4 is a sectional view of FIG. 3 showing the attachment of the bracket to the clamp and its relationship to the vessel shown in FIGS. 1 and 2.
  • a clamp l which is adapted to fit about the periphery of the vessel at the point of juncture between the top portion 2 and the body portion of the vessel 3.
  • This clamp is a sectional clamp which is provided with a series of interconnecting sections for an example, three in number, A, B, and C in this particular instance, which are held at respective pivot points 4,5.
  • the clamp adjustment with respect to the joint to which it is applied can be made by properly positioning of the entire clamp around the periphery of the vessel.
  • the clamp is secured (by means of band 13) at Y by a screw (bolt) or other suitable means.
  • a clamp retaining arrangement which consists of a long pin 6 having a T-shaped end 9 extending from a handle 7 and is adapted to be 3 inserted into and through a pair of guide members 8 which secured the T-shaped end 9.
  • Bracket 8 For purposes of enabling the clamp when opened to remain positioned on the body of the vessel freeing the operator to remove the body 3 for cleaning purposes, there is provided a bracket 8.
  • the bracket 8 is shown fastened to the body of the clamp 1 through a suitable means such as (a second) bracket 9 welded to clamp 1.
  • Bracket 8 in turn consists of two basic parts:
  • a flat angular portion 9 which is attached to the clamp l as well as a portion 10 which is disposed on top of portion 9 and slidably connected thereto via slots 11.
  • the top portion 10 in turn, has an end upright member 12 and extends such that it can be positively held in place on top of the vessel 2 through a suitable means such as a circular band 13.
  • the band 13, in turn, is provided with a locking arrangement 14 such that by ordinary fastening means, i.e., a nut and bolt arrangement, the band 13 is positioned around the periphery of the top of the vessel 2, and in turn positions the upper portion of the bracket 8 with respect to the clamp 1. Once the clamp l is in position, and the bracket 8 is held in place, the vessel operates in its normal mode.
  • the slots 11 in FIG. 3 indicate how a lateral movement of the bracket 8 enables the clamp to dislodge itself from the periphery of the vessel. This enables the body 3 shown in FIG. 2 to be removed without spilling and facilitates removal of the spent bag.
  • band 13 holding the member 12 of the bracket 10 in place the clamp does not fall to the ground once it is in the opened position, in this connection reference is made to FIG. 2.
  • the amount of lateral movement of the clamp with respect to the vessel when such clamp is in the open position can be best seen from FIG. 3 where the slots are elongated in an amount equal to the lateral movement of the clamp in the opened position.
  • the pivotal arrangement of the clamp is intended to move about such pivot points as 5 and 4, in this case pivot point 4.
  • FIG. 4 more clearly illustrates by means of a sectional view the relationship of the bracket 8 as it is held in position with respect to the top of the vessel and the body of the vessel.
  • the vessel When used inline, the vessel is held in place at the inlet and outlet means (not shown) and it is quite obvious that the operator is free to use both hands in separating the top and bottom of the vessel while in no manner being concerned with the clamp falling apart and subsequently falling to the ground.
  • the extent of lateral movement of the clamp as determined by the slots 11 is variable and can be altered in accordance with the surrounding piping and environmental requirements which may vary from condition to condition.
  • the clamp can be suitably tightened without in any manner affecting the ability of the bracket 8 to be laterally moved, since such movement is determined by the amount of play available through slot 11.
  • a clamp assembly for securing the abutting ends of the upper and lower portions of a pressure vessel comprising, in combination, closure means having at least two curved sections pivotally attached to each other to form a unitary structure having a pair of mating open ends; fastening means attached to the open ends of said closure means adapted to adjustably fasten said closure means about the pressure vessel adjacent the abutting ends of the upper and lower portions; a circular band concentrically disposed with respect to said closure means and in cooperative relationship therewith for attachment to the upper portion of said pressure vessel; fastening means associated with said circular band adapted to fixedly adjust said band on said upper portion of the pressure vessel; and adjustable bracket means fixedly attached to said closure means and to said circular band and adapted to pennit the lateral movement of said closure means with respect to said band.
  • bracket means includes a top member attached to said circular band at point along the outer periphery of said band; a bottom member affixed to said 7 closure means and slidably attached to said top memher; and adjustable means connecting said top member and said bottom member to control the extent of lateral movement of said bracket members with respect to one another.
