Two sets of assembling fixtures are mounted respectively on the two faces of the base structure so that one of the two sets of fixtures can be moved into operative position by turning the base structure into one of two diametrically opposed angular positions about the axis thereof. ## Claims ### Claim 1 A two-shift automatic assembling apparatus for selectively assembling at least one component member to an incomplete work of a first model or at least one component member to an incomplete work of a second model during each cycle of operation of the apparatus, comprising: a frame structure for accomodating at least a portion of one of said incomplete works of the first and second models therewithin and for permitting each of the incomplete works to be conveyed in a longitudinal direction therethrough, and a base structure supported on said frame structure and having two parallel opposite faces, said base structure being rotatable between two diametrically opposite angular positions about an axis fixed with respect to said frame structure and substantially parallel with said two faces of the base structure and with said longitudinal direction, and two sets of assembling fixtures detachably mounted on said two faces, respectively, of the base structure, each set of said assembling fixtures including work gauge means adapted to hold each of said incomplete works in a predetermined position with respect to said frame structure, carrier means adapted to carry each of said component members from the outside of said frame structure into a predetermined position within the frame structure, and parts gauge means adapted to transfer the component member from said predetermined position thereof into a predetermined ready-for-assembly position with respect to the work held in position by said work gauge means. ### Claim 2 (depends on 1) An apparatus according to claim 1, further comprising connecting means for joining each of said component members to each of said incomplete works during each cycle of operation of the assembling apparatus. ### Claim 3 (depends on 1) An apparatus according to claim 1, further comprising drive means for driving said base structure between said two angular positions thereof. ### Claim 4 (depends on 1) An apparatus according to claim 1, further comprising a rotary-type electric connector assembly which comprises first and second cables for electrical connection to said two sets of assembling fixtures and a third cable for electrical connection to external sources of current and which is operable for providing connection from said third cable to one of said first and second cables depending upon the angular position of said base structure. ### Claim 5 (depends on 4) An apparatus according to claim 4, in which said connector assembly further comprises two contact blocks each carrying contact elements, the contact elements on one of the contact blocks being connected to each of said first and second cables and the contact elements on the other contact block being connected to said third cable and being operable for connection respectively to the contact elements on the former contact block, one of the two contact blocks being rotatable with said base structure about an axis substantially aligned with the axis of rotation of said base structure and the other of the contact blocks being axially movable toward and away from the former contact block. ### Claim 6 (depends on 4) An apparatus according to claim 4, in which said connector assembly further comprises a first contact block carrying two sets of contact elements and a second contact block carrying a single set of contact elements which are equal in number to each set of contact elements on said first contact block, one set of contact elements on the first contact block being arranged within one half of the cross sectional area of the first contact block and the other set of contact elements on the first contact block being arranged within the other half of the cross sectional area of the first contact block and respectively in symmetry to said one set of contact elements with respect to an axis substantially aligned with said axis of rotation of said base structure. ### Claim 7 (depends on 6) An apparatus according to claim 6, in which said first contact block is rotatable with said base structure about an axis substantially aligned with the axis of rotation of the base structure and in which said second contact block is axially movable toward and away from said first contact block. ### Claim 8 (depends on 1) A two-shift automatic assembling apparatus as set forth in claim 1, in which said assembling apparatus further comprises stop means for preventing said base structure from turning beyond said two angular positions when the base structure is turned into one of the two angular positions.
