WORK-GUIDE FOR SEWING-MACHINES.

Specification of Letters Patent.

Patented Dec. 24,1907.

Application filed October 26, 1906. Serial No. 340,767.

To all whom it may concern:

Be it known that I, LOUIS N. BISHOP, a citizen of the United States, residing at Dayton, in the county of Campbell and State of Kentucky, have invented new and useful Improvements in Work-Guides for Sewing-Machines, of which the following is a specificatlon.

This invention relates to work guides for sewing machines, and the object thereof is to provide a work guide for producing in a ready, feasible and convenient manner uniformity in curved shapes when manufacturing articles of wearing apparel or other articles of manufacture for. which the work guide is applicable.

A further object of the invention is to provide a work guide-which will cause the work disposed over the guiding surface to retain a concavo-convex or bulged contour which is particularly advantageous in lining structures for application over the rounded parts of a body, such for example as the shoulders, over the breast and other parts requiring a concave or convex contour.

A further object of the invention is to provide a work guide which is particularly advantageous for sewing seams where one length of cloth is desired shorterthan the other.

With the foregoing and other objects in view, the invention consists of the novel construction of work guide as hereinafter more specifically described and illustrated in the accompanying drawin s, wherein is shown an arrangement of wor guide in accordance with this invention, but it will be understood that changes, variations and modifications can be resorted to which come within the sco e of the claims hereunto appended.

n describing the invention in detail reference is had to the accompanying drawings wherein like reference characters denote corresponding parts throughout the several views and in which Figure 1 is a sectional view through the bed-plate of a sewing machine showing one form of work guide in accordance with this invention. Fig. 2 is a like view of another form. Fig. 3 is a perspective view of the bed-plate showing the form of guide illustrated in Fig. 1. Fig. 4 is a view similar to Fig. 3 of the form of guide shown in Fig. 2. Fig. 5 is a top plan of Fig. 1. Fig. 6 is a perspective view showing one form of a detachable work guide. Fig. 7 is a sectional view thereof.

Referring to Figs. 1 and 3 of the drawings,

1 denotes the table and 2 the bed-plate of a sewing machine, the bed-plate being suitably secured to the table and having one end thereof depressed, as at 3, in a concaved manner so as to form a concaved guiding surface which constitutes a guide for the work. The depressed portion of the bed-pl ate 2 ap proximately centrally of one end thereof is slotted to permit of the operation of the feed and also to receive the throat plate 4, the latter being flat.

Referring to Figs. 2 and 4 of the drawings, the reference character 5 denotes the table and 6 the bed-plate of the sewing machine. The latter is flat and at one end approximately centrally thereof is formed with a U shaped slot 7, and in the slot 7 is secured a removable throat plate having the sides and one end depending in a curvilinear manner, as at 8, and which terminate in the flattened portion) at the bottom of the throat plate, the said flattened portion 9 being substantially of a width equal to the length'of the feed. The throat plate is provided with an opening 10 to permit of the operation of the feed 11.

In Figs. 6 and 7 of the drawings, a removable work guide is shown, and which is ada ted to be secured to the bed-plate 12. he guide shown in Fig. 6 comprises a pair of side portions and an intermediate ortion, the latter being indicated by the reference character 13, is flat and terminates in the side ortions. These latter are substantially o' inverted V-shape in cross section and are indicated by the reference characters 14, 15. The intermediate portion 13 is provided with a slot 16 to permit of the operation of the needle and feed, and is furthermore provided with a pair of openings 17 through which extend holdfast devices for detachably securing the work guide in position. Each end of each of the. side portions 14, 15 is beveled, as at 18, which facilitates the work in as much as there is no obstruction to the sliding of the material over the guide. Owing to the constructing of the side portions of V-shape in cross section and the intermediate portion of the guide flat, which rests directly uponthe bedplate of the sewing machine, it is evident that the opposing walls of the side portions of the guide and the intermediate portion 13 form a depressed working surface for the material in by producing the hollow curved shape deas much as the material has to ride over the apex of one side portion, then down over one wall thereof, over the intermediate portion 13, and then up over the inner wall of the other side portion, and then over the apex of the said last mentioned side portion. I

The guide as shown in Fig. 6, when used, is slipped over the top of the table of a sewing machine below the needle and then detachably secured in position.

Any of the forms of work guides as shown has its guiding surface of such contour that the work when disposed thereover will be made to retain a concavo-convex or bulged contour, as will be evident, and it will also be evident that such construction of guide is very advantageous when forming parts requiring a curved contour, and furthermore when sewing seams through two lengths of cloth when one length is desired to be shorter than the other. By the employment of a work guide in accordance with this invention the same overcomes the present mode of forming curved parts, the procedure being to hold the parts together to form the curved shape, that is to say, when the cloth is being sewed, the operator holds the feeding end of the cloth aloof from the table of the machine whereas, if a work guide in accordance with this invention is employed, the material would simply follow its course downwardly and upwardly over the guiding surface, thereslred.

What I claim is:

1. A work guide for sewing machines having a pair of side portions and a depressed intermediate portion, said side portions having beveled ends.

2. A work guide for sewing machines comprising a guiding surface having a flat intermediate portion terminating in side portions, each of which extends upwardly and outwardly at an inclination, said intermediate portion constituting a seat for the presser foot and in connection with the sides adapted to impart a curvilinear shape to the work, said intermediate portion of the guiding surface having a slot at its bottom to allow of the operation of the needle and feed.

3. A work guide for sewing machines hav ing a pair of upwardly extending side portions, the outer and inner faces of which extend at an inclination, and a fiat intermediate portion terminating at the bottom of the inner face of each of the side portions, said intermediate portion having a slot to allow of the operation of the needle and feed.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
