Definitions

  • the object of the invention toretain the tumbling action and at the same time to reduce the obstruction so that-in electroplating the process can be carried out at' -lower voltage and more-expeditiously. Also for other treatments it is advantageous to remove the obstructionbetwen-the interior and exterior.
  • the invention consists in a means for tumbling the work with free communication for the fluid between the -interior and exterior of the tumbling means.
  • the invention further consists in the construction of a tumbling barrel formed of a plurality of segmental members which together are of an angular magnitude considerably less than 360 to leave an open segment, together with intermittent rotating means .for said members through-which this open segment is always above the work.
  • Figure l is a longitudinal section through .the improved tumbling apparatus on the line -1--1 of Figure 2.
  • Figures 3, 4and 5 are diagrammatic cross sections "showing the various positions of parts during rotation and tumbling action.
  • Figurefi is a perspective view of one of the baskets
  • Figure 7 is a perspective view of the two baskets in nested relation with certain parts omitted for clarity.
  • a and B are segmental "b'as'ket' members rotatable about a common axis and conriect'ecl' to each other by hollow trunnons C at opposite entls'thereof. Construction of one of the members (B).
  • FIG. 6 This view shows the stepped end The other of the member shown.
  • the baskets are nested ICC together in-such a manner that the supporting hub A of basketaA-ris on the opposite end of supporting hub B of basket B the members overlap each other to form, in eifect, a single basket which is considerably less than 360 to leave a large open segment as shown in Fig. 7.
  • Each basket. is in fixed axial relation to the other as is obvious from the assembly shown in Figs. 1 and 7 and these basket members are also relatively movable and as will later appear, they are shifted from a position where the overlap .ison one side thereof to a position where it- .ison the opposite side. As specifically shown,.
  • these segments are polygonal with eccentric portions having bounding .sides with one of its bounding .sides of greater radius than the other so that each will overlap the other on one side and underlap on the opposite side.
  • the trunnions are supported ,in-a-frame including vertical members D and D to the lower ends of which the trunnions are connected and a cross member or frame E at the upper end.
  • the members of each of the pairs A and A A and A B and B and-B and B overlap and are rigidly secured to each other to form stepped end walls of baskets A and B respectively.
  • Members A and B are the peripheral walls and have the .leadingedge at a greater distance from center of rotation than the trailing edge.
  • the overlappingportions A and A of the basket A are outside the portions -B ofthe-basket Bbothradially and axially.
  • the trunnions Care non-revolublyaattached to the members D- and D and revoluble sleeve members C and C surrounding the members Cextend through the hubs A? and B of -the-end-walls A and B and beyond the same.
  • Gear wheels- F and F rotatable about sleeves C and C are on respective baskets A and B so as to move with the individual baskets. Therefore one gear wheel forms asupport and-driving member for the basket A and the other for thebasketB.
  • the gear wheels F and F are inmesh-withzdriving gear wheels G and G which latter are-connected by a shaft H- so that both rotate together. However the gear wheels F and Fhave their teeth interrupted atF so as to passrout of mesh with. the .teeth of the gear wheels G and G during a portion of each rotation; These interrupted portions in the two gears F and Fare so located with respect to each basket that when the basketis in the under or work supporting posi tion, the gear is out .of mesh with its driving gearG or G, and when: the basket is displaced from this position, the gear is in mesh with its respective drive gear.
  • the member B will still be .driven and as aconsequence, it will move across theopen segment which is above the work withdrawing its underlapping trailing end consisting of walls B and -B -from.the member -A and moving its advance end consisting. of walls B B and B into overlapping engagement withthe'opposite side of the member A.
  • member B will then propel member A to ..move with it until gear F of member A is in mesh with its drive gear.
  • member B reaches on the .underside in work supporting position its further movennent.
  • insulated electric cables I are extended in through the hollow trunnions to the pile of work resting on the lower basket and the ends of said cables have metallic portions I for conducting current to the work and forming a cathode thereof.
  • the anode is outside of the baskets and is preferably in two portions on opposite sides thereof so that one portion is always adjacent to the open segment for free passage of the ions between the anode and cathode.
  • the small part work pieces are loaded into the baskets A and B through the opening therebetween and are there in electrical connection with the cathode terminals of the cables I.
  • the two baskets A and B rotate together through a portion of the cycle but when each is in a position below the work therein, it will be permitted to rest while the member above the work will be moved to withdraw its underlapping portion from the resting member and to move it into overlapping relation with the opposite side of said member.
  • the member B is at the bottom and is resting, the member A having its trailing portion underlapping the member B or to the left, it being assumed that the rotation is in clockwise direction.
  • each basket at its trailing end has an inwardly projecting rake portion K at an oblique angle to the radius. This operates to direct the tumbling work farther to the rear in the resting basket and avoid overloading of its portion forward of the axis to cause a reverse oscillation.
  • a tumbling holder for processing small parts comprising a pair of independently rotatable segmental cylindrical baskets having portions adapted for overlapping each other alternately on opposite sides, and when thus overlapped on one side leaving a relatively large open angular segment between their opposite sides, each basket being in fixed axial relation to the other and having one of its bounding sides of greater radius than the other and means for intermittently and alternately rotating each of said baskets in one and the same direction through a partial revolution about a common horizontal axis with an interval of rest between successive movements of each basket during which it is in supporting position for the work therein, each basket during its movement shifting the overlap from one side to the other thereof with the open segment always above the work.
  • each basket has a segmental portion of larger radius than that of its trailing side to overlap the outer face of the trailing side of the other basket.
  • each basket has a radially inwardly projecting rake which directs the work tumbling therefrom into the basket at rest farther to the rear in the latter. thereby checking tendency to reverse oscillation.
  • each interrupted gear while out of mesh with its driving gear is remeshed therewith after an interval through the rotation of its basket by the basket in rear thereof.
  • a tumbling holder for processing small work parts comprising a plurality of segmental cylindrical baskets having portions adapted to overlap each other and rotatable in the same direction about a common horizontal axis and through successive revolutions, each basket being in fixed axial relation to the other and having one of its bounding sides of greater radius than the other said baskets together when overlapped having an angular magnitude sufficiently less than 360 to leave a large open segment, and means for alternately rotating each basket through a partial revolution while said open segment is above the axis and in advance of the basket being rotated, thereby closing the opening and opening a segment to the rear which also is above the axis and propelling the basket in advance. whereby during continuing tumbling of the work one of said baskets is always beneath to support the same and the open areas are out of the tumbling path.
  • a tumbling holder for processing small work parts comprising a pair of like segmental baskets rotatable about a commonhorizontal axis and together having an angular magnitude of less than 360, leaving an open segment therebetween, each basket being in fixed axial relation to the other and having one of its bounding sides of greater radius than the other each basket being the mirror image of the other and having stepped end walls, means for intermittently and alternately rotating each basket in one and the same direction through a partial revolution with an intermediate period of rest during which each is below and in a position to support all of the work, said open segment being above and out of the tumbling path of the work and changing from one side to the other of each basket while stationary.
