JOHN C. HINGE, OF BRIDGEBORT, CONNECTICUT, ASSIGNOR TO THE SING-EB MANU- FACTURING COMPANY,

GEARING.

A CORPORATION OF NEW JERSEY.

Patented Jan. 16, 1912 Application filedJ'uly 14, 1910. Serial No. 571,885.

To all whom it may concern:

Be it known that I, JOHN C. RINGE, a citizen of the United States, residing at Bridgeport, in the county of Fairficld and State of Connecticut, have invented certain new and useful Improvements in Gearing,

which the following is a specification, reference being had therein to the accompany-- ing drawings.

This invention relates to improvements in sewing machines and has particular reference to the means employed for manually determining the vertical position of the needles with respect to the fabric when the sewing machine is at rest.

In the manufacture of certain classes of productions, it is desirable to mount the sewing machine head with its front end facing the operator, and when the frame is of the ordinary length 'ployed hand or belt wheel mounted upon I the rear end of the needle-driving shaft is so far removed .manua'l manlpulation ard and belt wheel.

bevel gear -4 the hand wheel provided 1 represents the commonly-employed main or needle bar-actuating shaft,.2 a bevel gear wheel or power-transmitting member car-' ried by said shaft, 3 the hand wheel shaft, with a hub 5 and secured by screw 6 upon the shaft 3, the latter at its inner end being mounted in a bearing 7 formed in a boss 8, which latter in the present instance is cast integral with the sewing machine bracket arm 9, the hub 5 being mounted .in the tubular portion 10 of the boss 8. Carried by the shaft 3 is a wheel or power-transmitting member 11 which at the will of the operator,

and the arm standard of the ordinary height the commonly-emthrough the manipulation of the hand wheel 4, is caused to mesh with the member 2 to turn the shaft 1. i 1

Located inside of the bracket arm is a catch lever 12 pivoted upon a screw 13, the rear end of said lever having .secured to it one end of a chain connection 14, the opposite end of which latter is connected with a suitable foot treadle 20, a spring 15 normally acting to hold the free end 16 lever downward.

17 is a spring mounted upon the shaft 3 with its inner'end seated against the wall 18 of the bearing 7, the opposite end of said spring acting upon the inner end of the hub 5 to normally hold'the member 11 out of engagement with the member 2. v

The arrow .9 indicates the direction of the feed of the material.

While a preferred form of wheel for operatively connecting the main shaft with the hand wheel shaft is herein shown, it will be evident that the commonly-employed powertransmitting friction disks might be substituted therefor, and that the gear carried by the main shaft might comprise the adjustable power-transmitting element instead of the gear carried by the hand wheel shaft, Without materially afiecting the utility of the improved mechanism, the gist of the in- ,vention lying in providing said main shaft with temporarily connected means for-rotating it independent of its .belt driven pulley.

In the operation of the device, supposing the parts to occupy the positions shown in the drawing and it is desired tocommence the stitching operation, the operator rocks the lever 12, in opposition to the spring 15, which removes the end 16 of the catch lever from engagement with the Wall 19 of the member 11, thus permitting the spring 17 to disengage the member 11 from engagement with the member 2, which releases the manually-controlled mechanism from engagement with the actuating mechanism of the sewing machine during the stitching operation. Then the machine is again brought to rest and it is desired to register the needle at a point different from that at which it was brought to rest, the operator, througluthe manipulation of the hand wheel 4, moves the member 11 into operative relationship with of said catch the member 2 Where it is held by the end 16 of the lever 12 acting against the wall 19 ofhe member 11, as shown in the drawing.

laim:

In a power-transmitting mechanism, a ro-' tary main-shaft, a rotary hand-Wheel shaft havingits axis of rotation in a direction transverse to the axis of said main-shaftand having sliding movements in the direction of its length, power-transmitting members one of which is carried by said main-shaft,

its coacting member being carried by said hand-Wheel shaft, a latchfor holding said transmitting members in engagement, and means including a spring and a treadle for 15 discontinuing the engagement of said powertransmitting members.

In testimony whereof, I have slgned my name to this specification, in the presence of two subscribmg Witnesses.
