wma-mienne MACHINE.

`Be it known that I, GUNNAR EMANUEL EHRLINc,-a citizen of the United States, residing at Chicago, in the county of Cook l*and "fiStateof Illinois, have invented .a certain vnew and useful Improvement in Wire-Twist- -ing Machines, of which. the following is a means for twisting a wire for lubricating such specification.

My invention relates toimprovements '1n wire twisting means, and has for some of lts objects lto provide a ne'nf` and improved tieabout the neck Aof a bag or other pgckage; to provide means 'twisting means; to minimize the wear on the 'twisting means, land to inclo'se Vall the working-parts in an oil casing.

The invention is illustrated more vor less 'diagrammatically the .accompanying drawings, whereinf-l i '-with cover removed; Fig; Qis "a section on the Vline 2-2of Fig. 1 with cover in place; Fig. 3 is a longitudinal v,section through a modified form showing'my'invention applied to a hand'tool; Fig. 4'is a section on the une 4 4 of Fig. a.

Like parts are llndica'ted by like letters throughout the several igures.

Referring irst to the bench in Figs. 1`and'2, along rectangular boi: A is divided by a transverse partition A-1 into a spring chamber A? and twisting chamber A3. TheA rod- Ai passes through the partition A1 and the end wall Als of the box, said end wall being provided with a stuiiing box A6. Y Y -v is a twisting head on the outer end of the rod and from it project outwardly the twisting spring ngers AB having hooks A9 in their lends to 'engage the tie A1 which is to be twisted aboutthe neck of the bag A11.

long rack B1 inthe chamber A.

B is a short'worm or helical gear `rigidly mounted on the rod A4 and in mesh with a is located beneath the rod though' in mesh with the gear so that a longitudinal movement of the rod ,will cause its rotation by virtue of the interlockingof the rack and WOIIII.

chambers AZ- and As and removably held in position 'byascrews B5.

. In o rder to provide means for adjusting the twist given'to 'the wire, it is only necessary to limit the longitudinal movement of the rod because the number of twists bear direct relation to the distance the rod is` moved. In order lto provide for this the .inside wall of the chamber A3 is provided 1n the preferred form with three notches, C, C1, C2 and in one of these notches is llocated a stop plate'C4 notched as indicated to pass over and straddle the rod and pro-4 ]ect down providing a Istop against which the gear B may impinge. It will be understood that this stop is held in place by the cover and when that is removed the stop -plate may be withdrawn or placed in any one ofl the notches at the will 'of the oper? ator; The lugs C5 are provided so that the box maybe bolted orotherwise fastened to a work bench or table.

In the hand form shown in Figs. 3 and 4, the hollow handle D is provided at its smaller end with a bearing sleeve D1 and stuffing box Dzifor the rod D3, the rod having on the end the wire twisting means D4. Access to thev interior of the hollow handle is obtained by` means of the screw-threaded plug E and in this hollow interior is' located a short worm 'or helical gear El on the inner end of the rod D3.V This gear is. in mesh with a lon rack E2 held in position on the handle the screws E3( The rack is shown as semi-circular in cross section so as to make it conform with the inlterior of the handle. No spring-is here-"provided Il'tvill be understood that the rod D is stift, and the bearingl)1 guides and holdsit in position; and it is this stiifnessof the rod a d this tubular b'earing D1 which come bin 'to hold the gear E1 in mesh with the rad? E?. This combination is possible only of ourse owing to the shortness and rela-V tive rigidity and heaviness of the rod.
