Abstract
A sewing machine head having a tubular or free-arm type bed extending from the upstanding column and overhanging the base plate of the machine head and also having a front and a rear auxiliary bed each pivotally secured to the base plate along the front or rear edge thereof. When swung up, the auxiliary beds form a flat work-supporting table of extended area in cooperation with the tubular bed. With such bed structure, convertion between the free-arm type and flat-table type bed settings can be effected with extreme ease and efficiency. The auxiliary beds can also be utilized as a case for storing bobbins, needles, screw drivers, etc., eliminating the need for any separate storing cases.

- a vertical column upstanding from one end portion of said base plate;
- an elongate tubular bed extending substantially horizontally from a lower portion of said vertical column in overhanging relation to said base plate;
- a front auxiliary bed including a substantially rectangular hollow box-like body opening on one side thereof and pivotally secured to said base plate along the front edge thereof, by means of a pair of supporting legs formed on said box-like body, for swinging movement to and from an upright position in which the open side of said box-like body faces said tubular bed, said box-like body, as swung into said upright position, having a wide planar top portion formed to define a front auxiliary work-supporting table surface in substantially the same plane as the top surface of said tubular bed, a narrow bottom portion provided with said pair of supporting legs and a pair of substantially sector-shaped opposite end walls diverging upwardly from said bottom portion to said top portion;
- and a rear auxiliary bed including a substantially rectangular hollow box-like body opening on one side thereof and pivotally secured to said base plate along the rear edge thereof, by means of a pair of supporting legs formed on the second-mentioned box-like body, for swing movement to and from an upright position in which the open side of the box-like body faces said tubular bed, said box-like body of said rear auxiliary bed, as swung into said upright position, having a wide planar top portion formed to define a rear auxiliary work-supporting table surface in substantially the same plane as the top surface of said tubular bed, a narrow bottom portion provided with said pair of supporting legs, and a pair of substantially sector-shaped opposite end walls diverging upwardly from said bottom portion to said top portion:
- both said front and rear auxiliary beds further including a cover plate fitted to the open side of said box-like body to afford access to the interior thereof, and partitions and holding means, arranged in said box-like body to enable the latter to be used as a case for storing accessories and other articles.
