Qranford, Nail, assignor to The Singer (Iornpany, a corporation of New jersey Fil d ept. 25, 1962, Ser. No. 226,105 3 Claims. (Q1. 112-217.1)

This invention relates to sewing machine cabinets and more particularly to tubular metallic stands designed to support the wooden table portions of the cabinets, and an important object of the present invention is to provide an improved stand of this character.

Another object of the invention is to provide a sewing machine cabinet stand that is light in weight and which can be shipped at low expense.

A further object of the invention is to provide a sewing machine cabinet stand that is inexpensive to manufacture but which is also strong.

A still further object of the invention is to provide a sewing machine cabinet stand that can be manufactured in small factories where extensive manufacturing facilities are not available.

With the above and other objects in view, as will hereinafter appear, the invention comprises the devices, combinations and arrangements of parts hereinafter set forth and illustrated in the accompanying drawings of a preferred embodiment of the invention, from which the several features of the invention and the advantages attained thereby, will be readily understood by those skilled in the art.

In the drawings:

FIG. 1 is a front elevational view of a sewing machine cabinet stand embodying the present invention,

FIG. 2 is a right side elevational view of the stand shown in FIG. 1,

FIG. 3 is a top plan view of the stand,

FIG. 4 is a rear elevational view of the stand,

FIG. 5 is a left side view of the stand,

FIG. 6 is a fragmentary sectional view taken substantially on the line 6--6 of FIG. 5,

FIG. 7 is a fragmentary sectional view taken on the line 7-7 of FIG. 1,

FIG. 8 is a fragmentary sectional view taken on the line 8-8 of FIG. 2, and

FIG. 9 is a fragmentary sectional view taken substantially on the line 9-9 of FIG. 3.

The present invention is shown in the accompanying drawings as comprising a metallic stand 18 designed to support a wooden table portion (not shown) in a well known manner as shown, for example, in United States Patent No. 1,556,378. The stand 18 of the present invention comprises a pair of upstanding

front legs

21 and 22 the upper ends of which are integrally connected by an integral inverted U-shaped top reach 23. The stand 18 also has a pair of upstanding

rear legs

26 and 27, the upper end of each of the

legs

26 and 27 terminating in a rearwardly extending horizontal top lug 28. The reach 23 is drilled as at 29 and the lugs 28 are drilled as at 36, thereby providing means for securing the wooden table portion (not shown) to the stand 18. The front leg 21 is connected (FIG. 5) to the rear leg 26 by means of a substantially O-shaped side bracket 31 having a front post 32 and a rear post 33. The

posts

32 and 33 converge upwardly and at their upper ends are connected by an integral top rail 36, and at their lower ends are connected by an integral lower rail 37. The front leg 22 is connected (FIG. 2) to the rear leag 27 by means of a substantially O-shaped side bracket 41 having a front post 42 and a rear post 43. The

posts

42 and 43 converge upwardly and at their upper ends are connected by an integral top rail 46 and at their lower ends are connected 3,168,886 Patented Feb. 9, 1965 by an integral lower rail 47. A plurality of screws 49, passing through holes in the

posts

32, and 42, are threaded into the

legs

21 and 22, thereby respectively fastening the

front legs

21 and 22 to the brackets 31 and 41. Screws 49 also fasten the brackets 31 and 41 respectively to the

rear legs

26 and 27. Because the

posts

32 and 33 converge upwardly, the

legs

21 and 26 converge upwardly and because the

posts

42 and 43 converge upwardly, the

legs

22 and 27 converge upwardly. Also, as best seen in FIG. 1, the

front legs

21 and 22 converge upwardly, and as best seen in FIG. 4 the

rear legs

26 and 27 converge upwardly.

The side bracket 31 is connected to the side bracket 41 by means of a treadle support bar 51 (FIGS. 1, 4 and 6) opposite ends of which are curved upwardly as at 52 and formed with hooks 53 designed to fit over the

lower rails

37 and 47. Each hook 53 is formed with a hole and a screw 54 pass through this hole and is threaded into either the rail 37 or the rail47 as the case may be. The horizontal span 56 of the bar 51 is formed with a pair of upstanding spaced lugs 57 which carry pintles 58 for supporting a conventional treadle 59, which 'may be of the type shown in United States design Patent No. D. 185,081.

The upper portion of the

rear legs

26 and 27 are con nected by a cross bar 61, opposite ends of which are formed integral with the

legs

26 and 27. A J-shaped apertured pulleyguide 62 is fastened to the cross bar 61 by means of a screw 63.

The top rail 46, as best seen in FIGS. 2 and 3, has formed integral therewith a cylindrical bearing housing 66 which is positioned at right angles to the top rail 46. i The bearing housing 66 encloses ball bearings: (not shown) and thereby supports a shaft 67 the free end of which protrudes from the housing 66, and a hub 68 of a band wheel 69 is fastened to the shaft 67 by means of a set screw. The band wheel 69, the outer circumference of which is formed with a pulley groove 71, is equipped with an olfset crank 72 which, in a known manner, is turnably connected to the upper end of a treadle rod 73, the lower end of which is pivotally connected to a pin 74 carried by one corner of the treadle 59.

The top rail 46, by means of a brace (FIGS. 3 and 9') having a semi-cylindrical arm 76, a horizontal outreaching arm 77, and depending outreaching arm 78-, supports a dress guard 79. The semi-cylindrical arm 76 is secured to the top rail 46 by means of a screw 81, and one end of the arm 76 is formed integral with one end of the horizontal arm 77. The other end of the semi-cylindrical arm 76 supports the upper end of the depending arm 78. The distal ends of the

arms

77 and 78 are secured to portions of the dress guard 79 which dress guard 79 surrounds a portion of the band wheel 69.

The lower ends of the front and

rear legs

21, 22, 26, and 27 are equipped with plastic feet 82.

The stand 18 may be disassembled for shipping and/ or storage by removing four screws 49 from the bracket 31, four screws 49 from the bracket 41, and two screws 54 from the treadle support bar 51. This greatly reduces the size of package needed for packaging the stand.

When in use, wood screws pass upwardly through the holes 2929 in the top reach 23 and through holes 30- 319 in the lugs 282S and are screwed into wooden parts of a wooden table portion (not shown) of the cabinet. The present metallic stand 18 is especially advantageous because it can largely be manufactured from tubular parts by the simple processes of bending and welding and thus can be manufactured in small factories where extensive manufacturing facilities are not available. In fact the tubular stand 18 of the present invention, is designed to be manufactured anywhere in the world where factories are equipped to manufacture small devices such as bicycles.
