Application filed August 9, 1912. Serial No. 714,216.

To (HZ whom i may concern Be it known that 1, CHARLES T. E. GOULD, a citizen oi the UnitcdStates, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sewing-Machines, of which the following is a specification.

This invex'ltion relates to improvements in sewing machines, and has for one of its principal objects the provision of means whereby the sleeves, legs, and circular portions of garments can be conveniently placed on the machine and manipulated, so as to be readily stitched thereby as desired, and also, that the machincmay be used for ordinary or plain sewing.

A second ObJQCt of my invention is the provision of an oil proof casing for the lower operating parts and of means to pre- 'ent the spilling of oil it the casing is turned over on one side.

A third object of my invention is to improve and simplify the mechanism for operating the feeding device of the machine and .to improve the method of changing the feed.

A fourth object is to improve and simplify the means for retaining the shuttle in a retary hook or holder whereby the shuttle may be more readily inspect-ed, inserted, and removed, while being held securely in place during operation.

A fifth object of the invention is to pro vide means whereby the mechanism for operating the feeding device and the bobbincase ma he more conveniently inspected and access thereto easily had.

11 further object resides in detailed parts and the arrangementand combination of parts hereinafter described.

In the accompanying drawings which serve to illustrate the invention Figure l, is a front elevation of a sewing machine embodying the improvements. Fig. 2, is a side elevation taken from the left of Fig. 1, the upper part being broken away and part being sectioned on line 22, of Fig. 1. Fig. 3, is plan view or" a portion of' Fig. 1, parts being removed and parts being broken away. Fig. l, is a plan view of Fig. 1, with the central cover plate removed. Fig. 5, is a'sectional viewv on the line 55, of Fig. 1, parts being broken and the interior mechanism being-removed. Fig. 6, is a detail viewof the removable piece deed to inclose the shuttle mechanism. Figs. 7, 8, and 9, are detail "the arms and two the ring 15,, Whic embrace thefoutcr end portion of Fig. 4. Fig. 11, is a detail plan view of the feeding device and adjoining parts, the central cover omitted in Fig. 4, bemg shown in place. Fig. 12, is an eleva tional View partly in section of the parts shown in Fig. 10, and Fig. 13, is a View taken from the same position as Fig. 12, but with the cap piece removed and the gate swung outward as when removing or inserting a bobbin and the case therefor.

Referring particularly to the drawings, 1, is a base plate made integral with thewell 2, and the trough or case 3. Mounted on the plate 1, is a casting 4, which supports the driving wheeland the needle operating mechanism. However, my invention does not relate in any way to parts supported by or carried with the casting l, except as to the feed regulating device described below which lies partly within this casting. It is obvious however, that I intend to drive the wheel 5, b a belt inthe usual manner.'; As shown in ig. 4, I employ a connecting rod 6, within the castin 4. This rod 6, trans mits the motion of the shaft (not shown) of the wheel 5, to a crank 7, attached to the in- .ner or right hand end of a shaft 8, which runs through the length of the trough 3. At the outer or left hand end of thetrough 3, is a rotary hook 9, carried and driven by the shaft 8. A bobbin-case 19, is shown in place within the hook in Figs. 10, and. 12, but is omitted in Fig. 13. The particular bobbin case and ,bobbin mechanism shown are not my invention. At the left of the hook, however, is my improved gate structure 11, for holding the bobbin-case in the hook. This ate may be used in conjunction with any term of rotary machine having a bobbincase. As shown oartieularly in Fig. 10, the trough 3, has a vie its left hand 'or/o ter end. 'Bhe wall 12, has acut-out porti n 2, into thh upper face of which is thread w a screw 1, This screw. supports a bite e- 13 integral with the bracket arm- 14*, t lthe outerl end of which the gate 11, is piv ted.

The gate strueti e compri fitlan annular ring 15, pivoted to the bracket arm by means of a pin which passes through lugs 15, integral with tical integral wall 12, near causing a Yibration. of arm 39, and reciprocation of the feeding device, pivoted thereto. The isciprocating motion of the feeding ClCzTlCB guided by the flanges on the member which engage the outer face of the Wall 12. The wall 12, has an aperture 55, through which ihe bar 39, ex-

tends and which accou'imodates the project ing lugs of the member 2 8, to which the arm 39, pivoted.

The vertical n'iorsinent or the feeding (levice 3-1, is caused by :1 cam 56, car led on the shaft 8, on the outside oi the Wall 12, there being a bearing blOCli 5. fastened to the under face of the member 38, and endesired osition b 1 the nut (31 which is adjustable in the slot 62. Adjustment of the nut 81, longicudinally of the slot moves the pivot point 53, and consequently moves the wedge 4-9, back and forth heluteen the lug 51, and the end of the lug l8, the lcngth oi the throw of the arm 35), being determined by the Width of the wedge at the point between the two lugs l8, and 51. As appears in Fig. 10, the lever 39, is inclined downwardly from its point of support and the spring 52, also inclines downwardly to its point of contact with arm 39. it is an impo tant feature oi my invention that the: plate l, is intcgral with the body oi? he Well and also with the trough 3. This affords a rigid construction giving: a firm base for the casting 4, which rests directl on the bed plate as shown in. Fig. l. By having the trough and well integral I avoid the possibility of the e :a ie of oil from joints in the base of the machine, the integral Wall 12, at. the outer end of the trough 3, assisting; in this purpose by preventing the. escape of oil from the trough at the outer end. "lhc trough 3, is also proi'ided. with rcccsscs or grooi es (33. ii its upright walls which are dcsigncd to catch oil in cssc the machine is turned over on its side. All oil coming from the trough 3, and the casting 1-, collects in the well 52, since the trough and the casting open into the well. The bottom of the well is closed by a removable cap llel, provided with a flange ('35, threaded to the exterior of the well. he heightof the fiance (i5, is stiflicient to prcvcnt the overflow of oil when the The cap piece A le igs which is inserzed at one end under the edge ,of the casting 4:, While the other end is fastened to the top of the Wall 12, by means of the screw 69. Atv the end of the plate 68,

opposite the wall 12, the plate is notched so that it may the pin 3'0, shown in dotted lines in Fig. s, also appearinq in Fig. 5. The casting 4-, and the pin 76, hold the inner end of the plate 68, securely in posi-' tion and yet allow it to be readily moved when 'the screw 1'39, is removed A marked advantage of my machine over prior constructions, is its adaptability to darning hose and. other circular articles. With this object in View I have made the trough 3, small and with regular outline so that a stocking may be readily pulled over it. The special design of my bobbin case and feed driving devices enable me to place them in a small space, thus reducing the necessary size'of the trough.

Also the bed plate 1, is provided with two.

long slots or grooves 71, and 72, one on each side of the trough 3, and running parallel therewith, permitting a. stocking to he readilydrawn overthe trougl The edges of the slot- 71, and 72, are notched in the usual manner so as to retain long slide- plates 73, and 74, which may-be pushed bani; to the right under the casting when it is desired. to do dalfning or circular work, but which are placed in position shown in the Fig. s, when the machine is to be used for other purposes.) It of course necessary the bed plate 1, shall be cntirrly disconnectcd from the trough for a. considerable distance in order to follow this method ope am 1,, but the stocking cannot be run on the trough farther than the casting l, and thcrelorc, beyond this pointl make the bcdplaiie integral for mechanical rcasons, the opening 71-72, being reduced to mere shallow grooves 7172, in Which the plates 73-74, may lie during the darnin g' operation. It; will be seen, however, thatthe casting spans these grooves ind rests firmly on the base plate 1.

It will be LlllflifilShOOEl that various lllmllllt what I claiin as new and desire to secure by Letters-Patent is- 1. In a sewing machine, the combination section connected to the lower portion of said plate and having horizontally extending grooves angular in cross SeCtlon in the upper portion of HS walls for retaining oil when 1 the trough is placed on its side.

2. In a sewing. machine, the combination with a base plate, of a horizontally extending trough connected to the lower pOfl-iOn oi" said plate and terminating at one of its ends in a well for holding oil drippings, and a detachable cap secured on the lower portion of'said Well.

3. A sewing ,machine comprising in commaniac bination a horizontal plate provided With ltwo parallel slots extended longitudinally i therein, a trough shaped casing open at its top and locateijl intermediate said slots, and

g a slidablc nieniher located in each of said slots and in the opening of the trough to i open and close the same.

l. In a sewing machine in combination, a plate. a bar provided with projections at its l opposite ends attached to the bottom'ofsaid plate. and a cap piece provided with Web members i' .r sliding); helweenssail plan: and said projections to hold sail cap in place.
