Application filed February 1 i,-'1 9 )8, Serial Nit 'lbell' who1n. ttjanay;.jconcem: j

Beit known thattl', z'ltromas- GQPLANT, citizen ofthe United.States', residing at Bo'ston',: inthe county. oii Su-fiolkendi State of Massachusetts, have invented-Ian iImp'rove ment in Sole-SewingMachines,of whicl1 the accompanying: drawingaqisfe "specification,

partsa I v M p p The invention to be hereinafter described relates to sole SGWJH'g mQClXIHGS and moreing partsof the machined-urine thesewing operation.

As well known by those skilled in the art, 3 solesewing machines are providedwithfa through the work and engages the sewing thread at the oppositeside thereof, andathrough and while still in the work. Theneedle usually asses through the work from;

ously contact with the Work.

'lVith these considerations 1!} View, the object of the present invention is tOzPlOVldQ the work is protected from injuriouscontact rts of the machine, espec ally the looper,--during the sewing operatiOI1T ".J

The -invention will best be understood from the following description taken in connection with the accompanying drawings, which show one form oreinbodiment df the inven! tion which is more'jdefinitely defined as to its scope by the claims.

Figure l is a partial side elcvation of'sufficient portions of a sole sewing machine'to disclose the relation of the present invention thereto, certain parts being broken away and others being shown in section; and Fig. 2 is a front elevation showing sufiicient portions of the sole sewing machine to make clear the relation of the invention thereto,

In the drawings, the frame 1 ma be of E any usual or desired construction suitable for supporting the operating parts of the t 'machine, and these also-may be of any usual i SOLE-SEWING MACHINE;

SenerNQesas E or -particulai type Meunte'd Yup-ob the-- ma chine frame- 1 :is a table wiiieh-aconstitutes; the work? support upon wh-iehthe world-3; rests during; the; sewing" operation.- Dis posedabove-the table 2'15 the presserioot-el' which may beef any' usual or desired type:

The handle 8 is employedior lock ing the door of the shuttlebox in position.

Also 'nifounted-on the machine 'framel is the maintake-up arnr 9' andthe auxiliary take up 10, said parts being ofusuald orin,and construct on and, tornnng'no part, of the present invention, need no. further descrip Disposed below the table on work support Skis-the looper '11 carried by the actuatmg [ajrna v12 which is itselt' operated n' theusualnitt nier to give to the, loop-3r sub stantially circular. about; the needle 13 when the latter has pen'etrated and passed througli the -work to a-=position below the 1 table 2. 1 Front the" construction above generally outlined and Whichis usual inthis class ol machines' and well understood by those skilled in. the art, it will be noted that thelooper 11 during its substantially circularniotionaboutthe needle is liable to contact with the upper of a shoe, as indicated by dotted" lines in Fig. 1. Especially is this liable to ha pen, in passing around certain portions 0f"'th e sole, when the shoe upper -is carried somewhat to the left, in Fig. l. or turned about the work support or table 2 in 'order that the line of stitches may take the vdesiatetlmposition with reference te theinseanrwhich secures the ulpperto the insole.

will not be injured, the flexible guard vielding under such contact, as will be well understood.

The guard 14: is carried by a guard support 15, being secured thereto by means of screws or rivets 16, the edge of the guard 14 resting upon a shoulder 17 formed on the V guard support.

T he guard support 15 is pivotally mounted on the machine frame 1 at 18, F ig. 1, and has a tail piece 19 which, when the guard and guard support are raised into operative position as shown by full lines in Fig. 1, con tacts with the frame 1' at 26 which constitutes a stop. in order to maintain the guard and guard plate in either operative or inoperative position, as desired, there is mounted in a suitable recess formed in the machine frame a spring pressed plunger 21 which. acts upon the shoulders 22, 23, respectively, when the guard support is placed in operative or inoperative position, as indicated.

While it is desirable that the 14 shall be interposed between the looper and the work during the sewing operation, it is equally desirable at times that the looper and adjacent mechanism disposed back of the guard 1.4 be readily accessible, as well. understood by those familiar with this class of machines, and the hinged mounting of the guard support provides means whereby the guard be readily turned into operative or inoperative position and held in either of said positions without further attention on the part of the operative.

What is claimed is 1. In a sole-sewing machine, the combination of the work support, the needle and looper, means for moving the looper about the needle, a guard support mounted on the machine frame to be moved into and out of operative position, and a guard sustained by said support to protect the work from conflexible guard saunas in front of the looper to protect the work supported on the work support from contact by the looper as the latter carries the thread about the needle.

3.. In a sole-sewing machine, the combination of the work support, the needle and looper, means for moving the looper about the needle, a guard, a guard support mounted upon the machine frame to swing the guard into and out of operative position in front of the looper to protect the work supported on the work support from contact by the looper as the latter carries the thread about the needle, and means for holding the guard in either operative or inoperative position.

4.. In a sole-sewing machine, the combination of the work support, the needle and looper, a flexible guard disposed below the work support in front of the looper, a guard support hinged to the machine frame and carrying said guard, a spring for holding the guard support and guard in either operative or inoperative position, and a stop to limit the movement of the guard support and guard in one direction.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
