FEEDING MECHANlSh/l FOR SEWING=MACHINES.

SPECIFICATION forming part of Letters Patent No. 695,269, dated March 1 1, 1902.

Application filed August 16, 1901- Serial No. 72,255. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK OLIVER BERG, a citizen of the United States, and a resident of Spokane, in the county of Spokane and State of Washington, have invented a new and Improved Feeding Mechanism for Sewing-lvlachines, of which the following is a full, clear, and exact description.

This invention relates particularly to feeding attachments for that class of sewing-machines run rapidly by a motor to sew long seams in material; and the object is to provide a simple device operating to draw the stitched goods from the machine,leaving both hands of the operator free to feed the goods to the machine. The work of drawing the goods from the machine after stitching under the present method requires an extra attendant.

I will describe a sewing-machine attachment embodying my invention and then point out the novel features in the appended claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of a sewing machine with an attachment embodying my invention applied thereto. Fig. 2 is a side view of the attachment, and Fig. 3 is a detail view of a modification hereinafter more fully described.

Referring to the drawings, 1 designates a sewing-machine of the usual construction employed in heavy work and for sewing long seamssuch, for instance, as in awnings, tents, 85c. Rearward of the needle of the machine are drawing-rollers 2 and 3, between which the stitched material passes and which are designed to draw the material from the needle and keep the same taut. The lower roller 2 is mounted on a shaft 4, having a bearing at one end on a standard 5, attached to the machine-table 6, and at the other end it has a bearin g in a standard 7, also attached to the machine-table. The upper roller 3 is mounted on a shaft 8, having a bearing at its forward end ina hanger 9, supported by an arm 10, extended transversely of the machine from a standard 11, mounted on the machinetable, and this arm is held from any possible swinging movement by means of a brace connection with the sewing-machine arm. A band-pulley 12 is attached to the shaft L, and also on this shaft f is a gear-wheel13, meshing with a gear-wheel 14 on the upper shaft.

In operation the bandwheel 12 may be driven by a band leading from any desired motor, and obviously the rotation of the pulley 12 will impart motion to the drawing-rod ers 2 and 3, causing said rollers to draw the work from the machine, as before mentioned.

I may dispense with the upper shaft 8 and the gear-wheel 14, in which case a spring 15 is attached at one end to the arm 10 and bears at its other end upon the hanger 9, supporting the roller 3, as shown in Fig. 3, this hanger being mounted to slide on the arm. Equally good results are obtained as under the construction shownin Fig. 1, and more room is afforded for the passage of the goods.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination with a sewing-machine, of a feeding-roller having its shaft bearing in standards on the machine-body, a pulley on said shaft, an arm supported on the machine, a brace connection between said arm and the machine-arm, a hanger on said arm and arranged to slide, a spring connection between the arm and hanger, and a roller supported in the hanger above the first-named roller.

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

FREDERICK OLIVER BERG.
