' 1930. H. ALLBOOK Er AL FUR OVERSEAMING MACHINE 2 Sheets-sheet 2 Filed March 15 1928 A m F the usual casing admits of.-

with an extension 26 which is pivoted to one end of a member 27 the other end of which is connected to or is formed integral with the strap 28 of an eccentric 29 whereby said link 7, 26, is rocked thereby, impartingoscillations to the looper carrier 1 longitudinally of the machine and at the same time imparting the required liftthereto.

The swinging links 7 maintain the position of the looper carrier 1 transversely of the ma chine and by adjusting them to one. side or the other the looper carrier will receive corresponding transverse adjustment. Adjustment o'f said links 7 i will also serve to take up any slack caused by wear.

The front and rear supports of the looper carrier, that is to say the trunnion pins 4 in front andthe spindle 14 at the rear, are as already stated, as far apart as the dimensions of In order to vary the amount orextent of lift imparted to the looper 3 all'that'is neces sary is to loosen the clamp 12 (by screw 80) referred to and to adjust the stud 13- carried 1 therein (and consequently the bearing 2, spindle 14, and upper end of the link 15 mounted on said spindle) forwardly or'backwardly. This will cause the link 15, during the operation of the machine, to swingthrough a greater or less angle according to the adjustinentmade. i V V In 'o-rder to vary the lowest position to which the looper reaches without altering the amount of its lift, the stud 11 in the vertically disposed bearing 10 will be adjusted, a set screw 31 being providedto secure the stud in "adjusted position. Inorder that a very fine and'precise adjustment may be obtained,

we p'rovidethe stud 11 or clamp 12 with two lugs 32 the upper and lower 'faces ofwhich are respectively engaged by collars formed integrally with a second stud 38 that is screwed into thema'chine' casing so that by screwing it up or down the clamp will be correspondingly adjusted. The-upper end 3 1 of said collars may be suitably formed to be engaged by a screwdriver orspanner, 1 The looper bar ais provided justable' collar35.,and-a set screw.- Said bar is entered intothe tubular looper carrier un til said collar abuts against the front end of 'the carrier and is secured-in positioniby a collar36 and set screw on its rear'end, which] collar abuts againsta shoulder on the. car- -rier. 1

The collar on therear end of the bar is pref with an adbe understood that we do not limit the scope of our invention thereto.

What we claim as new, is z" .1. In anoversea-ming machine for fur and gloves, the combination of a main frame, a power shaft thereon, a horizontally movable needle, a looper above the needle and having forward and backward, up and down, and

sidewise movements, 2; looper carrier, .means for supporting the forward end of the looper carrier comprising a pair oflinks, supported fromthe frame and which aremut-ually adjustable for supporting the looper carrier between them. and operably connected with,

the power shaft for receiving a swinging mo tion, and means for supporting the rear end of the looper carrier comprising a longitudinally adjustable pin or stud supported from the frame so as to be parallel with theneedle and h'aving abearing, and ailink journaled in and depending from the bearing, and connected with the looper carrier.

2. In an overseaming. machine for furand gloves, 'the combination of a main frame, a. power shaft thereon, a horizontally movable needle, a looper above the needle and having forward and backward, up and down, and sidew se movements,.a looper carrier, means for supporting the forward end of the loopercarrier comprising a pair of links, supported from the frame and which are mutually adj ustable for supporting the looper carrier betweenthem, and operably connectedwith the power shaft for receiving a swinging mo-c. tion, and means for supporting the rear end 6f: the looper carrier comprising pin mounted on the frame 'in'vertically adjustable position, a clamp on the pin, a'horizontal'pin or stud secured adj ustably in the clamp and extending parallel with theneedle a'nd having a bearing,"and a link j our'naled infand depending from the bearing and connected with the looper carrier. i 1

3. In an overseaming machine for fur and gloves, the combination of a. main frame, a

vpower shaft thereon, a horizontally movable needle, a looper above the needle and having forward and backward, up and down, .and

sidewise movements, a looper carrier means for supporting the forward end oftheilooper carrier comprising a pair of links, supported fromith e frame and which aremutually. ad-

jus'table for supporting the looper carrier between" them, and operably connected witlL' the power shaft for receiving a swing motion,

and means for supporting the rear end of the looper carrier comprising a pinvertically slidable in the frame of the machine and supporting a, clamp, a, horizontal pin or stud secured to the clamp and extending parallel with the needle and having abearing, a link journaled in and depending from the bearing and connected with the looper carrier, and a screw parallel with and connected with the vertical pin and screwed into the frame for a,

vertical adjustment, whereby to alter the height of the looper.
