FEEDING DEVICE FOR SEWING MACHINES.

APPLICATION FILED NOV. 16, 1908.

1,001,388, Patented Aug. 22, 1911.

WITNESSES INVENTOR- HIS .ATTLTRNBYH ward as nearly as practicable to the needle, to the more effectually prevent the curling or rolling over of the goods at their edges. The foot Z) curves upward toward its front or toe end and the edge 6 adjacent to the side and periphery of the presser-wheel is in close proximity to the said wheel.

The letter we denotes a guide, having a shank m clamped in a holder I adjustable at right angles to the line of the feed. The adjustable holder 1 is shown as having dovetail connection with the needle plate sup port C, and its adjustment thereon is attained by means of the screw J. The said holder is also provided with the clamp K, which clamps the guide 972 securely to the holder. The guide on is located at the right of the needle, as viewed from the front of the machine, and extends forward providing a portion having a face m perpendicular to the plane of the top of the needle plate D against which face m the edges of the goods slide and by which said edges are guided. The said guide also extends rearwardly serving to guide the abutting edges of the goods and also providing a chaining finger m aroundwhich theoverseam stitches are formed and off the end of which they slip as the work feeds through the machine. The guide m being adjustable as already explained, it will be understood that the distance between the needle and the chaining finger m can be easily regulated to secure a desired depth of stitch.

The foot 6 engages the goods G intermediate the wheel a and the guide m, the sole 7) at one edge 6 following closely the edge of the wheel a as explained, while the opposite edge Z2 is substantially parallel with the perpendicular face m of the guide on. It will therefore be readily seen that the foot will be considerably wider at its toe than at its heel end. It will also be observed that in the arrangement of parts shown, one edge (72 of the foot Z) fitting closely to the presser-wheel a and both the wheel and the foot being attached to the same shank, they may be raised and lowered together without changing their relation to each other so that there need be no opening between the two elements of sufficient width for threads or any portion of the fabric to pass through or be caught in or wedged into, which objectionable condition would at times occur if the foot of the wheel were not raised and lowered together, as in such cases there would be an opening of varying width between the edge of the foot and the wheel. Further it will be seen that the edge 5 of the foot away from the presser wheel is parallel with the plane in which the foot moves and is adjusted and is also parallel with the side m ofthe guide m for the same purpose of preventing the catching or clogging of the goods between the foot and the guide, therefore, for the most accurate overscaining, the foot should be made of exactly the width to fill the space between the presser-wheel a and the guide m.

In utilizing this device the guide m may be adjusted with reference to the needle E to attain a desired width of stitch and the foot Z) is so adjusted upon the presser-shank end 0 that it will engage the goods when the presser shank is lowered, but will not bear 5 heavily enough upon them to retard or prevent their free feeding between the feed dog l? and the presser-wheel a. The guide 9% serves as a gage whereby the goods are readily introduced for overseaming and whereby a stitch of desired depth is readily maintained during the overseaming operation.

By referring particularly to Fig. 4 it will be seen that the presser-wheel a engages the j goods in close proximity to and at one side 5 of the needle, while the guide m engages the goods at the opposite side of the needle and more or less closely thereto as determined by its adjustment, while the foot 6, as before explained, engages the upper face of the goods in advance of the needle and so closely thereto that there is no opportunity for the curling or rolling over of the goods at their edges between the foot and the needle. A

Having thus described my invention, what "9'5 1 claim as new and desire to secure by Letters-Patent, is:

1. In a sewing machine, the combination with the needle and the work feeding de-i vice, of a presser-wheel, a foot, a support ioo for and common to both the wheel and the foot by which support the wheel and foot are moved in fixed relation only toward and from the work feeding device, the foot e being located entirely in advance of the'ios needle.

2. In a sewing machine, the combination with the needle and the work feeding device, of a presser wheel, a foot, a supports, for and common to both the wheel and the 'ilo foot by which support the wheel and footare moved in fixed relation only toward and from the work feeding device, the foot being adjustable on the support relatively... to the wheel and the foot being located cntirely in advance of the needle.

3. In a sewing machine, the combination with the needle-plate, the work feeding device and the needle, of a presser-wheel sup-,. ported with its axis oblique to the plane of the top of the needle plate, a foot adjacent to the presser-wheel and entirely in front of the needle and a support for the presser wheel and the foot by which support the wheel and foot are held in fixed relation and moved toward and from the work feeding device.

4. In a sewing machine, the combination with the needle plate, the work feeding de,.. vice and the needle, of a presser-wheel supported With its axis oblique to the plane of the top of the needle plate, a foot supported adjacent the presser-wheel and having a goods engaging surface or sole entirely in advance of the needle, the sole of the foot being made to conform approximately with the periphery of the presser-wheel and a support on which the prcsser-whecl and the foot are mounted in fixed relation to each other and by which they are moved in unison toward and from the work feeding device.

In a sewing machine, the combination with the needle-plate and the work -feeding device, of a presser-wheel supported with its axis oblique to the plane of the top of the needle-plate, an edge-guide having a surface perpendicular to the plane of the top of the needle-plate and a foot intermediate the presser-wheel and the guide, the edge of the foot next to the wheel being parallel with the adjacent portion of the wheel and the edge of the foot next to the guide being parallel with the perpendicular face thereof and a support for the presserwheel and the foot and a support for the guide.

6. In an overseaming machine including a needle, work support and feeding device, a n'esser-wheel with its axis oblique to the movement of the needle, a foot conforming to the edge of the prcsser-wheol and located entirely in front of the needle.
