Anthony J Mafuzas BY W fTOR/VEY WITNESS United States Patent SEWING MACHINE SPOOL-PIN SUPPORTS Anthony J. Matuzas, Union, N. J., assignor to The Singer Manufacturing Company, Elizabeth, N. .L, a corporafion of New Jersey Applicafion February 6, 1956, Serial No. 563,504

' 1 Claim. Cl. 112-218) This invention relates to sewing machines and more particularly to a new and improved means for supporting a spool of thread on a sewing machine.

A sewing machine, which is designed to be housed in 1 either a drop-head cabinet, of the type shown in U. S. Patent No. 2,673,776, or in a portable carrying case, of the type shown in U. S. Patent No. 1,548,915, should be as small as consistent with good design. Furthermore, any appurtenance, for example the spool-pin, secured to external surface of the sewing machine should protrude as little as possible. On the other hand, such a spoolpin should be set a sufficient distance away from the main portion of the' sewing machine to accommodate the largest sized spool of thread that would normally be used with the sewing machine. In order to reconcile these apparently diverse design requirements the present invention has as its primary object to provide an improved spool-pin which can selectively be moved close to the frame of the sewing machine or to a position in which it will support a large spool of thread.

Another object of the invention is to provide an improved spool-pin support for use with a family type sewing machine.

A still further object of the invention is to provide a sewing machine spool-pin which may be used to support a large spool of thread and which does not protrude an inafter 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.

Fig. 1 is a rear elevational view of a family-type sewing machine embodying the present invention,

Fig. 2 is a top plan view of the sewing machine shown in Fig. 1,

Fig. 3 is a sectional view taken substantially along the line 3-3 of Fig. 2, and

Fig. 4 is a perspective view of a portion of the sewing machine shown in Figs. 1, 2 and 3.

Referring more specifically to the drawings, the invention is disclosed as embodied in a sewing machine 14 having a base 16 from which rises a bracket-arm 17, comprising a standard 18, an overhanging arm 19, and a head 21. The sewing machine 14 has many conventional items including a hand-wheel 22, a presser-bar 23, a needle-bar 24 for supporting a needle (not shown), and a thread guide 26, which serves to guide-a thread to the needle, the thread guide 26 being located adjacent to the junction of the head 21 with the arm 19.

In accordance with the present invention, there is pro:

vided a means for adjustably mounting a spool-pin with respect to the bracket-arm 17. This means includes a shelf 27, preferably formed integral withzthe bracketarm 17 at a location adjacent to the junction of the arm -19 with the standard 18. The shelf 27.l1a's a depending boss 28 provided with a hole 29 through which passes a vertically disposed pivot screw 31 having a head 32, the screw 31 being held in place by a nut 33. The head 32 of the screw 31, and a dished spring washer 34, which surrounds a reduced portion of the head 32, are received in a recess 36 formed below the upper surface of an oblong spool-pin plate 37. Also, as best seen in Fig. 3, the reduced portion of the head 32 and a portion of the shank of the screw 31 are received in a hole 38 formed concentric with the recess 36. In order to provide for easy operation, a fiat washer 39 is positioned between the top of the shelf 27 and the bottom of the plate 37. As best seen in Figs. {2 and 4, the spool-pin plate 37 is oblong and has rounded ends 41 and 42. The free por tion of the plate 37, adjacent to the end 42, carries a vertically disposed spool-pin 43 having (Fig. 3) a feltwasher 44 on which rests a spool of thread 46. It will be noted that the ends 41 and 42 of the plate 37 are symmetrical and that the center lines of the pin 43 and the hole 3638 coincide with the longitudinal center line of the plate 37. Because part of the spool-pin 43 is located below the top of the arm 19 and because the spool-pin 43, when moved to the position shown by solid lines in Fig. 2, is close to the arm 17, there is provided an arrangement which allows the sewing machine to be housed conveniently in a drop-head cabinet or in a carrying case.

The herein disclosed invention functions in the following manner. When the sewing machine 14 is to be stored in ,a drop-head cabinet which may be similar to the drop-head cabinet shown in U. S. Patent No. 2,673,776, supra, or placed in a portable carrying case which may be similar to the portable carrying case shown in U. S. Patent No. 1,548,915, supra, the plate 37 and spoolpin 43 are turned to the position shown by solid lines in Fig. 2. This places the spool-pin 43 and the plate 37 close to the arm 19 of the sewing machine 14. With the parts in this position the sewing machine may be raised from or lowered into a drop-head cabinet or may be housed in a conventional carrying case. If, however, the sewing machine is to be used for sewing and it is desirable to use a large spool of thread, the plate 37 and spool-pin 43 are swung to the position shown by dotted lines in Fig. 2. This places the spool-pin 43 at a distance from the arm 19 and permits the use of a large spool of thread. It will be understood that the dished spring washer 34, the screw 31 and nut 33 press the plate 37 against the washer 39 and press the washer 39 against the shelf 27 with suflicient force that once the spool-pin plate 37 is pivotally set in one position, it will remain in that position until reset.

Having thus set forth the nature of the invention, what I claim herein is:

In combination, a sewing machine having an elongated overhanging arm: an elongated shelf secured to the rear side of said overhanging arm, the longitudinal dimension of said shelf being parallel to the longitudinal dimension of said overhanging arm, and the said shelf protruding from the rear of said overhanging arm a widthwise distance substantially equal to the diameter of a selective small sized spool, and the length of said shelf being equal to substantially twice the diameter of said selected small sized spools; a vertical pivot member carried by said shelf at a location closer to one end of said shelf than to the other end thereof; an elongated plate the length and width of which are substantially equal to the length,
