' embroidering machine having auniv'ersal Work-feeding mechanism manually control-' lable as to the direction of feed, as in the socalled Bonnaz typeof embroidering machine; In a preferred embodiment of the-present improvement, a commercially well known embroidering machine is adapted for em broidering hats and similar articles by interposing a suitable standard between theusual b'e'd plate and bracket-arm to raise the latter, the parts operating within the standard being-correspondingly lengthened, The usual throat-plateof' the machine is replaced by the base of'an upstanding tubular postwithin which is disposed the usual looper having merely a-lengthened shaft; Mounted upon the upper 'end of the post is a throat-plate cap having a depending flange embracing the post and apertured to receive a securing screw. To provide for readily'interchan'gin the throat plate "with others having di 'erent sizes of ne'edle-a jertures, the fiangeth'ereofis suitably notched to permit removal of'the throat-plate from t'hepost Without removal of the feeding-foot and nipple usually employed in these'machines,

Embracing the throat-plate flange and the upper portion-of the post is a tubular work- 's'upporting head provided internally thereof with vertically spaced bearing lu'gs engaging the post. For operating upont ubular or euppedarticl'es, this head presents a flariing work supporting surface'curving downwardlyfromthe t-hro'atpl ate in directions to 'en'circle'the"post;' To provide for conveniently interchanging different sizes "of E JERSEY, A CORPORATION ortnn'w SEWING MACI-II1\TE wean SUPPORT lazaf'seri i in; 363,775.

heads, they are divided longitudinally of the post'intopreferably half-sections which are in themselves interchangeable and individually secured upon the post. By means of this construction, the head-may be removed from the machine withoutdisturbing the post, the looper-mechanism or the feeding foot and nipple. Also the throat-plate may be removed by merely removing one of the headsections, Furthermore, the manufacture of the head is simplified by constructing it in duplicate sections, i

In the accompanying drawings, Fig. 1 is a front side elevation, partly in section, of an embroidering machine-having the present improved work-support, with the front section of the latter removed. Fig. 2 is a sectional view of the work-supporting post sub st'antially onthe line2'2, Fig. 1. Fig. 3 is a perspective view of one of the interchange able sections of the work-support. -Fig. 4 is a perspective view of the throat-plate. 5 is a perspectiveview of one of a pair of work-supportingsections which may be substituted for thoserepresented by Fig. 3; for smaller Work;

Referring to the drawings,- the bed-plate 1 and the overhanging bracket-arm 2, together With the mechanism sustained thereby are substantially the same as disclosed in my prior U: 8. Patent N0. 1,536,041, April; 28', 1925; In the'present machine, however, a tubular standard-section 3 is interposed between the bed-plate and bracket-arm'to elevate the latter therequired distance for employing a worlc'supporting post. I

Journaled in the bracket-armQ is the usual needleand feed-actuating shaft 4, which in'a-yjbe suitably coupled under manual control with the main-shaft 5 carrying-the belt-- pulley 6; Through the usual connections with the shaft 4:, the needle-bar 7 carrying a hook-needle 8 is reciprocated vertically, said needle-bar being constrained to partake of rotary movements about a vertical axis of the cylinder 9 derived from the shaft 10 journaled in'the bracket-arm 2. Also constrained to rotate with the cylinder 10 is the'feeding foot 11 which derives its work advancing movements from the: rotary shaft 4." Rotary if movements of the shaft 10 are manually controllable during the operation of the machine by means of a hand-crank 12, beneath the bedplate 1 and operatively connected with said shaft 10 by suitable shafts and gearing.

As usual, the work is stripped from the needle by means of the vertically reciprocatory nipple 13, which may be designed to function as a needle-stripper or as a combined braid-guide and needle-stripper as is well known." The present machine also includes the covering-thread guide 14 which, through suitable connections with the shaft 4, isrotatable in timed relation and at ,difl'erent s eeds with respect to the needle-reciprocations to wind a covering-thread about the thread-loops encliained by the needle. While the commercially well known embroidering machine head illustrated in the accompanying drawings has been selected for use with the present improved work-support, because of its adaptability for producing the desired embroidery effects, it is to be understood that the present invention in its broadest aspects is not limited to the specific stitch-forming and work-feeding.mechanisms disclosed in the drawings and referred to in this description in general terms.

The bed-plate 1, at its end opposite to the standard is regularly provided with a circular throat-plate recess 15, which in the pres entcase affords a seat for a circular, flanged base 16 of a vertically directed, tubular post 17. By referring to Fig. 2 of the drawings, it will be observed that the post 17 rises eccentrically from the circular base 16 which is de-v tachably secured to the bed-plate l by means of screws, as 18. The upper portion 19 of the post is reduced in diameter, thereby pro viding a shoulder 20, andhas interiorly thereof a wall 21 which is aperturedto form a bearing for the upper end of the elongated, vertical shaft 22 of theithread-presenting looper 23. y I

The lower end of the shaft 22 is journaled in the regular bearing-lug 24 depending from the bed-plate 1 and is oscillated in the usual manner by the endwise reciprocatory bar 25 deriving its movements fromgthe, shaft. 4 through connections of regular form but elongated to extend through'the machine standard. The looper shaft 22 is turned as usual, through connections between the hand-crank12 and the bar 25, whereby the looper position always corresponds with the needle position in diiferentdirections of feed of the work. I

' Capping the upper endof the post portion 19 is a throat-plate 26 having a needle-aperture 27 and a threading-implement aperture 28, Depending from the periphery of the throat-plate is a circular I flange 29 embracing the upper end ofthe post, said'fiange being partly cut away so that for one half of its circumference it is of less depth than the tally from its shank 32.

with modified head sections for dilferent classes and sizes of work. One form of these head sections is illustrated in Figs. 1 and 3 of the drawings and comprises a shank 32 which is semi-circular in cross section and is provided at its upper end with an outwardly extending flange of which the upper side affords a spherical work-supporting surface in combination with duplicate half-section 34. Of course, the flange 88 may be constructed to have a different conformation than that shown in the drawings, to meet the requirements of different articles to be stitched and may in fact constitute a flat work-supporting plate projecting horizon- Preferably, the shank 32 is provided interiorly'thereof with spaced bearing- ribs 35 and 36, of which the rib 36 is seatedupon the shoulder 20 of the post. Each of the half-sections is detachably securedupon the post-portion 19, by a screw, as 37, with only thebearing-ribs in direct contact with the post, the two-point contact of the work-supporting head wit-h the post afi'ordedby the spaced bearing-ribs providing for snugly fitting thehead-sections upon the post to thereby form a rigid work-support. k I

In Fig. 5 of the drawings, there illustrated a half-section 38, which with a, duplicate thereof forms a modified work-supporting head more particularly adapted for small sized tubular or cupped articles of work. It will be. observedthat this worksupporting head also has spaced bearingribs, as 39 and 40, for engaging the post and that each half-section is provided withan aperture 41 for entrance by a securing screw (not shown) to be threaded into an aperture, as 42, in the post portion 19. In each of the different types of heads, a clearance recess, as 43 is provided above the upper bearing rib for the throat-plate flange 29..

The present improvement, comprising sections which together encompass the post, affords a work-supportim surface permitting ready control of the work by an operator, regardless of the direction of feed. It also provides forreadily interchanging a pair of head-sections .with others adapted to meet diiferent requirements, whether for work of a flat character or for tubular work of different types or sizes.

Having thus set forth the nature of the invention, what 1 claim herein is 1. A work-support for sewing machines, comprising an upstanding post, a Work-supporting head divided lengthwise of the post to provide complemental sections having outwardly extending flanges together providing a work-supporting surface encompassing the post, and means for securing the head sections upon the post for lateral detachment therefrom.
