1 Claim. (Cl. 112-258) This invention relates to new and useful improvements in sewing machine stands and more particularly to stands for use with all types of commercially available sewing machines, and it is among the objects thereof to provide a sewing machine stand having a base, an upright column and an adaptor plate integrally formed whereby a sewing machine may be mounted with the proper overhang to make it conveniently accessible to the user, the device being especially adapted for use in factories manufacturing fabric products such as clothing.

It is a further object of the invention to provide a sewing machine stand in which the base and mounting plate, together with the power unit are arranged in such a manner that the sewing machine that is mounted on the adaptor plate is counterweighted, and further to make accessible the essential controls for operating the machine.

These and other objects of the invention will become more apparent from a consideration of the accompanying drawing constituting a part hereof in which like reference characters designate like parts and in which:

Figure 1 is an isometric view of a sewing machine stand embodying the principles of this invention; and

Figure 2, a top plan partially in section, of the adaptor plate taken along the line 2-2 of Figure 1.

In the drawing, the numeral 1 designates a tubular column or upright that is welded at 2 to a base 3 and is similarly joined at the top to an adaptor pulse. 4. The numeral 5 designates a sewing machine having a base 6 with the conventional depending components 7, the details of which need not be described as they vary with different types of machines. The adaptor plate 4 is provided with drill and tap holes 8 for receiving the mounting bolts 9 of the sewing machine 5, lock nuts 10 being provided to secure the sewing machine base 6 in its mounted position in adjustable spaced vertical relation to the adaptor plate to accommodate components 7. As shown in Figures 1 and 2, the tap holes may be drilled for various kinds of sewing machines, it being unimportant as to whether the adaptor plate 4 has more or less This is one of the convenient features of the invention, since it makes the stand interchangeable with any type of sewing machine. If, for example, one shop has two or three makes of sewing machines, the adaptor plates 4 can be drilled and tapped to receive any one so that quick replacement may be made when needed.

The adaptor plate is adapted to receive the base 11 of a motor 12 having a pulley 13 with a belt 14 that is connected to the sheave wheel 15 of the sewing machine, the belt passing through slots 16 of the adaptor plate 4 and the slot 17 of the sewing machine base 6, it being noted that the slot 16 is wider than the bolt 14 (see Fig. 1) so that upon mounting of a machine of slightly difierates Patent 0 "ice cut size or shape in different holes in the adaptor plate, the sheave wheel 15 and pulley 13 may be adjusted to remain in aligned relation. Obviously an additional slot 16 may be adapted for any major variation in the type of machine. The motor is adjustable by a mounting strap 18 to maintain suitable tension on the belt 14-. The motor is provided with a clutch mechanism operated by a bell crank lever 19 having a link connection 20 with a foot treadle 21 that is mounted on the base 3, as shown. A socket member 22 is provided for a conduit to supply power to the motor.

It is evident from the design and construction of the base, the adaptor plate and the integrally joined upright column 1, that the sewing machine base provides adequate clearance and may be extended to overhang the adaptor plate so that the machine and its controls are readily accessible to the operator. It is further apparent that the sewing machine stand is adapted for use with any type of sewing machine by simply fitting the machine base with the threaded rods to previously drilled and tapped holes laid out on the adaptor plate, and that by suitable positioning of the machine in selected holes in the adaptor plate an elfective counterweight is provided in the opposite location of the motor assembly relative to the main supporting column. It will also be seen that by spacing the base of the machine from the adaptor plate by means of adjustment of bolts 9 and lock nuts 10, adequate space for depending components 7 is provided regardless of the relative size thereof.

Although one embodiment of the invention has been herein illustrated and described, it will be evident to those skilled in the art that various modifications may be made in the details of construction without departing from the principles herein set forth.

We claim:

A sewing machine structure comprising, in combination, a base member, a supporting column, an adaptor plate having a plurality of bolt holes therein and a sewing machine having a driven pulley and a column mounted on a base secured to said adaptor plate by mounting bolts inserted in selected bolt holes according to the shape of the sewing machine, and locking nuts, said supporting column being offset from the center of the base member and adaptor plate to cause the adaptor plate to overhang a substantial portion of the area of the base member, a power unit having a drive pulley mounted beneath said adaptor plate on the side opposite the overhanging portion of said adaptor plate and the sewing machine being mounted on said adaptor plate on the overhanging side of said plate and with the sewing machine column olfset on the same side with said adaptor plate with respect to said supporting column to cause a counter-balancing eifect on the machine and its supporting stand, said drive pulley extending into alignment with the driven pulley of the sewing machine on the same side of said supporting column as the sewing machine column, said mounting bolts for securing said machine base to said adaptor plate being relatively long to space the sewing machine above said adaptor plate, said locking nuts permitting relative adjustment of the spaces between saidadaptor plate and the base of said sewing machine to accommodate sewing machine bases of different depths.
