'cable.

It will be understood thatI do not confine mysely to any particular construction of power device between the stationary rack G and the sewing machine D as a large variety of ways may be employed for imparting motive power to the sewing machine, though that shown is excellently adapted to the purpose. A clutch fmay be employed to disconnect the band wheel E from the gearing F to be used when the machine is to be run backward, but it is also clear that various methods may be employed to throw off the operation of the sewing machine during the return of the carriage. In some types of sewing machines there is a clutch upon the band wheel, and this might be connected or disconnected as required.

In the construction shown 011 sheet 2 I have the endless cable H, and in place of the rigid grip J, I provide a clutch shown in Fig. 6 consisting of four pulleys M arranged in pairs, two of which are carried upon spring hearin gs N. A frame it acts upon the outer ends of the spring bearings to depress them until the cable H is grasped under the action of an cecentric k moved by a lever K. When the spring bearings are depressed the pulleys M carried by said spring bearings are forced toward the pulleys M carried upon the stationary part of the grip, and this gradually grips the cable H with an elastic pressure, overcoming the danger to the apparatus which would result from suddenly gripping the This device constitutes an elastic gripping device and is the preferable form. The table or support and carriage, sewing machine, pulleys E, band 6, and gear F are substantially the same in the construction shown in Figs. 4 and 5 as in the case of Figs. 1 and 2. In place of the rack G, a stationary cable G is employed in the modification, the said cable being passed about a pulley L adapted to drive a gearing F for operating the sewing machine. The movement of the carriage 0 causes the pulley L to travel on the stationary cable G and thereby cause it to rotate with the speed commensurate to that of the travelof the carriage, thus causing the sewing machine to operate at the proper speed to insure uniform stitches when uniting the fabric.

I do not confine myself to any special details of construction as they may be modified more or less without departing from the principles of the invention.

What I claim as new, and desire to secure by Letters Patent, is

1. In a machine for sewing fabrics, the combination of a support for the fabric, a railway parallel to the support, a carriage adapted to travel upon the railway, a sewing machine secured to the carriage, the traveling cable,- the grip secured to the carriage adapted to grasp the cable, and power devices for operating the sewing machine substantially as set out.

2. In a machine for sewing fabrics, the combination of a support for the fabric, a railway parallel to the support, a carriage adapted to travel upon the railway, a sewing machine secured to the carriage, the traveling cable, the grip secured to the carriage adapted to grasp the cable, and power devices for operating the sewing machine consisting of a stationary part arranged parallel to the railway, a rotary part journaled upon the carriage and adapted to be rotated by the stationary part through frictional contact, and power transmitting devices between the rotary part and sewing machine substantially as set out.

3. In a machine for sewing fabrics, the combination of a support for the fabric, a railway parallel to the support, a carriageadapted to travel upon the railway, a sewing machine secured to the carriage, the traveling cable, the grip secured to the carriage adapted to grasp the cable, power devices for operating the sewing machine consisting of a stationary rack arranged parallel to the railway, gearing journaled upon the carriage and meshing with the said rack, and power transmitting connections'between the gearing and the sewing machine substantially as set out.

4. In a machine for sewing fabrics, the combination of a support for the fabric, a railway parallel to the support, a carriage adapted to travel upon the railway, a sewing machine secured to the carriage, the traveling cable, the grip secured to the carriage adapted to grasp the cable, and power devices for operating the sewing machine consisting of a stationary rack arranged parallel to the railway, gearing journaled upon the carriage and meshing with the said rack, and power transmitting connections between the gearing and the sewing machine, and means for throwing the sewing machine into or out of action substantially as set out.

5. In a machine for sewing fabrics, the combination of asupport for the fabric, a railway parallel to the support, a carriage adapted to travel upon the railway, a sewing machine secured to the carriage, a traveling cable, power devices for operating the sewing machine, and a grip carried with the carriage and having flexible or elastic gripping devices for gradually gripping the traveling cable to start the sewing machine gradually from a state of rest.

In testimony of which invention I have hereunto set my hand.

CHESTER MONEIL.
