Definitions

  • the present invention relates to a universal capsule holder for use as a component of a high speed amalgamator, the holder being capable of holding substantially all makes of capsules presently on the market.
  • This capsule holder has a retainer having a substantially cylindrical cup on each end thereof, and having a detent reciprocably confined in each cup, each detent being biased toward the center of the capsule holder.
  • Each detent has-an opening extending therethrough, the opening being defined by a tubular extension which extends-through the end of the retainer. This tubular extension thus defines an opening through which portions of certain capsules mightextend'during vibrationv thereof.
  • Each detent has a dished surface against which one end of the capsule abuts during the retention thereof. The dished surface has a circular shoulder formed therein to accommodate capsules having a circular squared end on one or both ends thereof. At the top of each detent, a portion of the dished surface is removed so as to facilitate the insertion of the capsule into the holder.
  • the tubular extension not only permits the neck or other extensions of certain capsules to extend therethrough during the-mixing operation, but also serves to guide each detent during reciprocable movement thereof.
  • the tubular extension also insures that the capsule extension or neck extends completely through the retainer and consequently that it does not hit,
  • each detent By biasing each detent toward the center of the capsule holder, this allows each detent to follow the capsule during the vibration thereof so as to be certain that the capsule is securely retained in the holder.
  • FIG. 1 is a perspective view of an amalgamator utilizing the present improved capsule holder.
  • FIG. 2 is an enlarged perspective view of the improved capsule holder per se, showing a capsule being inserted into the holder.
  • FIG. 3 is a side view of the improved capsuleholder.
  • FIG. 4 is a longitudinal cross-sectional view of the capsule holder.
  • FIG. 5 is a longitudinalcross-sectional view taken through line 5-5 at one end of the capsule'holder.
  • FIGL'6 is a transverse sectional view taken through line 6- 6 at one end of the capsule holder.”
  • a high speed'amalgamator 10 which includes timer-vibrator unit 12 having the present improved capsule holder 14 mounted on top thereof; as stated above present day high speed amalgamators are capable of operating at3200 to 3400 rpm.
  • a unit such as illustrated by the numeral 12 will move a capsule 16 contained withinholder l4 through a substantially FIG. 8 path as viewed from the top of amalgamator 10.
  • capsule l6 subjected to high rpms, but the capsule is subjected to a wide va riety of longitudinal and transverse force components during the vibrating thereof.
  • capsule holder 14 is comprised of two generally cylindrically-shaped cups 18 at each end thereof, each of these cups having a detent 20 reciprocably confined therein so as to clamp capsule I6 therebetween during the mixing or vibrating operation.
  • Each detent 20 has a dished surface 22 which assists in centering and retaining the capsule in place.
  • Each dished surface 22 has a portion 24 removed at the top of each detent so as tofacilitate the insertion of capsule 16 into the holder 14.
  • a rib 26 extends across the open space between cups 18, the rib being affixed to cover plate 28 by screws 30, the cover plate being securely fastened to a vibrator (not shown).
  • the vibrator transmits the vibratory motion to a shaft 36, the latter extending through opening 32 of casing 34. Because cover plate 28 is secured to shaft 36, the vibratory motion is transmitted to holder 14.
  • Retainer 17 includes an end wall 38 on each end thereof and a generally cylindrical side wall 40 extending inwardly towardthe center of the retainer. Together, the end walls 38 and the cylindrical side walls 40 define two generally cylindrically-shaped cups 18 on each end of retainer 17, cups 18 being spaced apart to define an open area 42 therebetween. As described above, a longitudinally extending rib 26 extends across open area 42 and connects cups 18 to each other; rib 26 also serves to connect holder 14 to cover plate 28 via screws 30, cover plate 28 being connected in turn to a high speed vibrator as described above.
  • each cup 18 Reciprocably confined or retained within each cup 18 is a detent which is biased toward the center of retainer 17 by a coil spring 44.
  • Detent 20 is reciprocably retained within cup 18 by means of a generally U- shaped retainer clip 21 which has an annular portion 48 and two generally parallel legs 50.
  • Retaining clip 21 is mounted around retainer 17 so that the legs 50 thereon extend into openings 52 formed in diametrically opposite sides of cylindrical walls 40.
  • Each leg 50 has a flatsurface 54 which slidably engages flat surface 56 each recess 58 which cut into the diametrically opposite sides of the outer diameter of an annular extension 60 formed on each detent.
  • Each recess 58 is a longitudinally extending recess which, in conjunction with retaining clip 21 and the openings 52 serves to control not only the stroke length of detent 20 within cup 18, but also prevents thegdetent from rotating about a longitudinal axis extending through retainer 17 and about which each cup 18 is formed. This'serves to keep the cut out portion 24 of dished surface 22 on the upper or top side of holder 14. As stated above, this serves to facilitate the insertion of a capsule 16 into holder 14 by allowing the ends of the capsule to be moved downwardly through removed portion 24 toward the center of detent 20.
  • Certain capsules which are on the market at the present time have a squared circular end which must be provided for if a capsule holder is to accommodate this capsule. Accordingly, a circular shoulder 68 is formed in the dished surface 22 of each detent. Thus, a capsule having such a squared circular end may be inserted into holder 14 with that end of the capsule facing in either direction.
  • capsules of substantially all shapes and sizes can be securely held or retained with the present holder so as to have the contents thereof thoroughly mixed during high speed vibration or mixing.
  • detents 20 will follow the longitudinal movements of the capsule throughout the. ,vibrating motion thereof during the mixing operation, thus insuring that the capsule will be securely retained within the holder.
  • a universal capsule holder for use on a high speed vibrator comprising:
  • an elongated retainer formed about a longitudinal axis, said retainer having an end wall at each end thereof, each of said end walls being substantially perpendicular to said axis, a cylindrical side wall formed about said axis and connected to and extending inwardly from each of said end walls toward the center of said retainer, said end walls together with said side walls defining two cups, each of said cups being spaced apart to define an open area therebetween to provide for the insertion of a capsule, and a rib extending across said open area and connected to each of said cups, said rib being adapted for connection to said vibrator;
  • each of said detents having a first portion having a circular cross section, the outer-diameter of each of said first portions being adapted to slidably cooperate with the inner annular surface of its associated cup, spring means disposed between each of said end walls and each of said detents for biasing said detents inwardly toward the center of said retainer, and means forming an opening through each of said detents, and about said axis, the surface of each detent which is disposed nearest the other detent being dished from said opening to assist in holding a capsule between said detents.
  • each of said end walls has a circular end opening therein and formed about said axis, said means comprising a tubularextension extending through the end opening of its associated cup, the outer diameter of each of said tubular extensions being less than the outer diameter of the first portion of its associated detent, and being adapted to slidingly cooperate with the end opening of its associated cup.
  • a capsule holder as set forth in claim 2 including means for reciprocably retaining each of saiddetents within its associated cup while simultaneously preventing the rotation of each of said detents about said axis, each of said dished surfaces having a portion thereof removed at the top of said holder to facilitate the insertion of a capsule between said detents.
  • each of said dished surfaces has at least one circular shoulder formed therein for receiving capsules having squared circular ends.
  • each of said first portions comprises an annular exteneach of said cylindrical walls, a recess formed in each of said detents disposed in alignment with the clip opening in its associated cup and a retainer clip mounted on each of said cups and having a portion thereof extending through the clip opening in its associated cup.
