Definitions

  • buttons extending radially outwardly through holes in a cylindrical shell to provide an expansion effect, are urged outwardly by an inflatable tube which is part of a readily insertable and removable unit including also end, tube carriers and an internal tube support. The ends of the tube are secured fluid-tightly between threaded outer surfaces of the tube carriers which engage the inside of the tube, and annular tooth-like ridges of inner surfaces of tube retaining sleeves which engage the outside of the tube.
  • An assembly of an inflatable tube for pressing buttons outwardly to expand the mandrel, tube carrying members connected to Opposite ends of the tube, one of said members having an air passage to permit ination of the tube, and a rigid, internal tube support, engaging both said members, constitute a unit which is readily insertable into and removable from a rigid cylindrical shell to facilitate assembly and service of the mandrel.
  • Both the buttons and springs for retracting the buttons are accessible from the exterior of the mandrel for removal for servicing, and the buttons are adaptable to receive outer leaves as expanding parts of the mandrel.
  • the invention also includes an arrangement wherein the opposite ends of the tube are secured fluid-tightly between threaded portions of the tube carrying members extending within the tube and annular tooth-like ridges of inner surfaces of tube retaining sleeves which engage the outside of the tube.
  • FIG. l is a central longitudinal sectional view of a preferred form of expansible mandrel according to this invention.
  • FIG. 2 is a transverse sectional view substantially on the line 2 2 of FIG. l; the parts being as when the man drel is in normal or non-expanded condition;
  • FIG. 3 is a View at the same line as in FIG. 2; the parts, however, being as when the mandrel is in expanded condition;
  • FIG. 4 is a transverse sectional view substantially on the line 4-4 of FIG. l; the parts being as when the mandrel is in normal or non-expanded condition;
  • FIG. 5 is a diagrammatic, perspective illustration of a leaf-type modification employing relatively broad leaves as outer expanding members
  • FIGS. 6 and 7 are transverse sectional views of the outer-leaf type of mandrel shown in FIG. 5; these views, respectively, being somewhat similar in general character to FIGS. 2 and 4, except that, in FIG. 7, the mandrel appears as in expanded condition rather than in its nonexpanded condition of FIG. 4.
  • the first embodiment illustrated in FIGS. 1 4, comprises a rigid, cylindrical shell 10, having journals 12 and 14 at its opposite ends, iixedly connected to the shell by set screws 16 and 18.
  • These leaves may either be single pieces, as illustrated, extending throughout the greater part of the distance between the journals 12 and 14 or each may be of two or more pieces approximately equaling the length of such a single piece leaf.
  • buttons 22 are suitably fixed thereto at suitable plural points therealong and extend into button holes 24 formed, in radial register therewith, in the shell 19.
  • buttons carriers 20 extends a unitary assembly 25 of an iniiatable tube 26 of rubber or other suitable resilient material, tube carrying members 28 and 36 to inner portions of which opposite ends of the tube are similarly air-tightly fixed by being tightly squeezed between retaining sleeves 32 having inner, annular tooth-like ridges 32a embedded in the outer surface of the tube, and threaded portions 28a and 30a of the members 28 and 3i) which are threaded with a squeeze iit into the tube and into internally threaded portions 32h of sleeves 32 at the latters outer ends.
  • ridges 32a are preferably directed toward the outer extremity of the adjacent end portion of the tube 26 to give greater assurance against the ends of said tube becoming dislodged from engagement Iwith the sleeves 32 and the threaded portions 28a and 30a of the members 23 and 36 when the tube is inated.
  • the assembly 25 also includes a relatively rigid supporting rod illustrated as a tube support 34, extending closely within the tube 26 when the latter is in normal non-inflated condition, with the opposite ends 36 of said rod seated firmly within complemental recesses 38 formed in the inner ends of the tube carrying members 28 and 3i) to space the latter precisely from each other.
  • the tube support 34 also serves to oppose inward collapse of the tube Z6 upon deflation of the latter and, if the tube support 34 is solid :as illustrated, said support also enables the tube to be inflated rapidly by limiting the volume of air which may be introduced thereinto.
  • buttons 22 When the tube 26 is deflated and supported by the support 34, the buttons 22 extend radially outwardly, substantially into the holes 24 to hold the button carriers 20 in their proper operating positions.
  • the buttons are of such length that, upon radially outward movement of said button carriers upon iniiation of the tube 26 as shown in FIG. 3, the buttons extend beyond the outer surface of the shell 10, thereby increasing the effective diameter of the mandrel.
  • Such retracting means are shown as plural compressed coil springs 40, each seated at its inner end upon an outer surface of a related button carrier 2i), preferably within a ⁇ depression 42 formed in said button carrier, and held within a related spring opening 44 -by ⁇ a peened-in plate or plug 46.
  • a plurality of such springs are provided for each button carrier 20, the spring openings 44 yand springs therein being suitably located in symmetrical relation to that ⁇ ,button carrier to apply button retraction force to the latter substantially uniformly therealong.
  • Each button 22 comprises :a headed nut 48 (FIG. 2) having its shank extending outwardly into a hole 5t! in a related button carrier and a cup-like body member 52 held with its lbottom against the outer end of said nut by a stud bolt 54.
  • the stud bolts head is within an outer end cup recess in the body member 52 and the bolts shank extends through a hole 56 in the bottom of the ybody member 52 and is threaded tightly into the nut 48.
  • the stud bolt 54 is accessible from the exterior of the mandrel to permit easy removal and replacement of the body 52 when necessary.
  • the plugs 46 holding the springs 40 in place are removable for replacement of springs as may be necessary by inserting a suitable pulling tool into a hole which may be drilled in :a plug, whereafter the plug m-ay be pulled from the shell 10 to permit spring removal and replacement. It will be seen that the springs 40, as with the principal parts of the buttons 22, are readily removable for servicing from the exterior of the mandrel.
  • An air pipe 58 into which air may -be introduced through a releasable check valve 60 at the open end of journal 14, extends within a bore 62 in the latter and 'is airtightly fixed at its inner end into a longitudinal bore 64 in the right, tube carrying member 30.
  • the bore 64 communicates with a cross-'bore 66 in the member 30 to carry air into the rubber tube 26 to inate the latter.
  • the button carriers 20 and their related lbuttons 22 are forced radially outwardly to eifect expansion of the mandrel, and the check valve 60 holds the air in the tube during the period of time in which expansion of the mandrel is to be maintained. Subsequent release of the valve 60 permits the tube to become ldetiated, thus permitting the button carriers and their related buttons to retract to restore the mandrel to its non-expanded condition.
  • the springs 40 serve as means operative directly upon the button carriers to afford greater assurance of such button retraction.
  • the unitary assembly 25 is completely formed, independently of other parts of the mandrel, by sliding the tube support 34 into the rubber tube 26, and sliding the retaining sleeves 32 onto the opposite ends lof the tube. Then, the left and right tube carrying members 28 and 30 are threaded into opposite ends of the rubber tube thereby seating the ends of the tube support 34 in the recesses 38 of said members.
  • the left end (as illustrated) of the shell 10 is secured by set screws 16 (only one being shown) to the journal 12, and the button carriers 20, with the
  • the air pipe 58 is threaded tightly into the end of the bore 64 in the member Sil, whereafter the right journal 14 is slid onto the outer end of the member 30 and fixed thereon by set screws 68 (only one Ibeing shown).
  • FIGS. 5-7 differs from the above-described first embodiment chieliy in the addition of elongate, external, expanding leaves 78 of arcuate shape in cross-section.
  • FIG. 5 diagrammatically discloses only the shell 10 and the leaves 70 to show clearly the relationship between those parts.
  • the leaves 70 are of such width that their side edges 72 come very close together when the mandrel is in contracted condition. Said leaves are connected to the inner leaves 20 by countersink-headed bolts 74 extending through countersunk holes 76 in the leaves 70', thence, through spacer sleeves 78 and into the headed nuts 48 into which they are tightly threaded.
