An arrangement for mounting a domestic appliance, such as a machine, within its cabinet that provides, in the case of sewing machine heads, both free arm to storage and flat bed to storage positions as well as a fifth position orienting the sewing machine to permit access to the machine, of side bobbin access type machines, bobbin from the top of the cabinet, with the connection of the appliance head to its cabinet being by way of a pair of fixed oppositely disposed pins at the front side of the assembly and a pair of oppositely disposed retractable pins spaced to the rear of the fixed pins, with the pairs of fixed and retractable pins cooperating with brackets located one each adjacent the respective ends of the head that are anchored to the cabinet, and with the sewing machine being oriented with regard to the fixed and movable pins such that the center of gravity of the sewing machine is located basically between the fixed and retractable pairs of pins, to provide a gravity assist biasing action on the sewing machine in effecting a number of the indicated positions of the sewing machine with respect to its cabinet.

In an applicance assembly that includes a parallepiped base on which the appliance is mounted, a quadrilateral shell having an open top forming a support for the appliance base, an appliance retracted position rest mounted on one side of the shell and projecting inwardly of same, with the appliance
In an applicance assembly that includes a parallepiped base on which the appliance is mounted, a quadrilateral shell having an open top forming a support for the appliance base, an appliance retracted position rest mounted on one side of the shell and projecting inwardly of same, with the appliance base being received within the shell adjacent the top thereof between the two shell sides that are normal to said one shell side, and means for adjustably mounting the base between said two sides of the shell for movement between upstanding positions at different levels in which the appliance base is horizontally disposed and the appliance is disposed exteriorly of the shell in upright operable positioning, and retracted positions in which the appliance engages the rest and the base is in depending relation from the shell, the improvement wherein: the mounting of the appliance on the base, and said mounting means, comprises: the base having a pair of aligned pins fixed to said base adjacent the side of the base that faces away from the rest, with one of said fixed pins projecting from one end of the base and the other of said fixed pins projecting from the other end of the base, with the base having mounted thereon adjacent the other side of the base a pair of aligned retractable pins, with one of said retractable pins projecting from said one end of the base and the other of said retractable pins projecting from said other end of the base, said retractable pins being mounted for movement axially thereof toward each other to dispose them in withdrawn positions relative to the base ends, and including means for resiliently biasing same to their respective projecting positions and handle means for simultaneously moving same to their withdrawn positions, with the appliance being fixed to the base above said pins, and including a first bracket secured to one of the two shell sides between which the base is disposed in supporting relation to those said pins that are at one end of the base, and a second bracket secured to the other of such two shell sides in supporting relation to those of said pins that are at the other end of the base, said brackets each including a vertical wall, with said brackets being secured to said shell in confronting relation, and said walls being in substantial parallelism and each being formed to define slot means in which said pins at either end of the base are received to support the appliance and base from the shell, said slot means of one of said walls being a mirror image of said slot means of the other of said walls, said slot means for each of said walls comprising, for the respective fixed pins, an upper horizontal slot portion having at the end of same projecting away from the one side of the shell a first appliance operating position seat adjacent a vertical stop surface, with said slot upper horizontal portion being open and connected to a curvilinear slot stem portion that arcs downwardly below said slot upper portion to a second appliance operating position pin seat substantially vertically aligned with said horizontal slot portion seat, said brackets each including a horizontal wall rigid with respect to the respective brackets and disposed above said slot means slot portion, said slot means for each of said walls comprising, for the respective retractable pins, an upper closed perimeter horizontal slot that is substantially level with said wall upper horizontal slot portions of said walls for said fixed pins, and having closed ends, with the end of same that is closest to said wall upper horizontal slot portion of the respective brackets forming a first appliance operation position seat, and an elongate curvilinear closed perimeter slot separated from and below the said closed perimeter upper horizontal slot of the respective walls and having its upper end substantially aligned with the other end of said closed perimeter upper slot and arcing downwardly to substantial vertical alignment with said closed perimeter slot seat, and thence defining a toe portion extending away from the wall fixed pin curvilinear stem slot portion that terminates in a second appliance operating position seat that is substantially level with said wall slot stem part pin seat, whereby, when at each bracket said pins are seated in said appliance first operation position seats of the respective wall slot means, the appliance is in its first operating position, and when at each bracket said pins are seated in said second appliance operating position seats of the respective wall slot means, the appliance is in its second operating position, with said retractable pins being retracted and then released to shift them between said separate slots of the respective walls defining said retractable pin slot means, with said fixed pins seated in the respective first and second appliance operating seats of said fixed pin slot means, and with said retractable pins free of both their slots of their slot means, the appliance may be disposed in one of its retracted positions, and with the weight of the appliance providing a rotational bias of the appliance in the direction of the rest, on release of said retractable pins, for assisting in the changing of the appliance between operating positions.
