IMPROVEMENT IN CLOTH-GUIDE AND BINDER-GAGE FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 56,7 [4, dated July 31, 1866; antedated July 25, 1866.

To allwhom "it may concern:

Be it known that I, L, T. OONANT, of New Lisbon, county of Ooluinbiana, and State of Ohio, hzwe invented and produced a new and useful machine for the purpose of doing away with the necessity of basting for the sewingmachine; and I do hereby declare that the following is a full and clear description of the same, reference being had to the accompanying drawings, and to the letters of reference in the same, which form part of this specification.

Figure 1 is a perspective drawing, exhibiting the various parts of the machine in combination and ready to be attached to the sewing-machine for use. The other figures represent the parts detached, and, when united, form my binding-guide.

A represents the body of the plate, which is corrugated, and is, as well as the other parts, made of metallic plates. The corrugations struck up from beneath give strength and rigidness to the plate, and allow the use of thinner and lighter material than could other wise be used, thus cheapening the expense of manufacturing.

B represents the fastening-slot, by means of which and a thumb-screw fitting into it the machine is fastened to the sewing-machine and adjusted to any required position. v

U 0 represent the gaging-lips, bent up at right angles to the body of the plate and provided with slots D E, for the parts M J to work through. The gaging-lips serve the purpose of keeping the edges of the cloth parallel while passing to the needle. Slot D allows a free perpendicular movement of the arms M M, whereby they are enabled to accommodate themselves to the varying thickness of the cloth while the edges of the lips keep the arms from turning sidewise. SlotE allows a free movement to the binding device, in order thatgfgoods. of different thicknesses may be bound. The edges of the gaging-lips assist injretaining the lips of the ,binder in their proper place.

F represents the upright post, which holds one end of the armszor plates M M steadily in their place, yet allowing a free perpendicular motion of the arms of the baster throughout their entire extent, thus allowing an even pressure or friction upon the cloth, no matter what is its thickness, from the gaging-lips to the points of the arms.

G is a screw secured to the base plate,

which, passing through slots in the binder J and the spring N, is provided with two nuts, I and H. The former nut adjusts the position of the binding-lips and the latter regulates the amount of pressure of the spring N on the arms M M.

J represents the adjustable spring clam pin gbinder, which consists of a piece of spring metal slotted and doubled together in the middle and provided with short lips or books on each end, the hooks or lips resting against and opposite each other, in which the binding to be used is inserted in the usual manner.

K represents a small separating-block, which is fitted on the adjusting-screw, between the arms of the binder, near the bend, in order that they may at all times be at the same distance apart, and at the same time form a solid surface, against which the nut 1 may work.

I represents the fastening-nut, by which the binder is secured in its proper place, that place depending upon the width of the binding material used.

L represents the slot of the binder, which allows a free horizontal adjustment of the binder, by which adjustment said binder is. made to accommodate itself to different widths of binding.

M M represent the arms, which hold smoothly and guide the cloth against the guide-lips. These arms are narrow and rigid, and are connected with, yet independent of, the baseplate, and held in position by means of the lips or sides of-the slotD and the upright post F. i At the gaging-lips, as they pass through the slot D, they are bent at an angle of about forty-five degrees from the line of the gaging-lips in the direction from which the cloth is coming.

The ends of the arms are slightly bent up,

as shown in Fig. 1, to facilitate the more easy.

introduction of a piece of cloth both under and between them.

The angle at which these arms are placed with regard to the line of seam, together with the gentle friction produced by the regulatingspring, automatically incline and direct the edges of the cloth against the gaging-lips, thus smoothing and guiding the material in a straight line to the binder and the needle.

N represents a spring, one end of which is fastened to the base-plate, while the other end rests upon the upper surface of the upper inclined arm M, about midway between the gaging-lips and the point of the arm. This spring is made to bear'with more or less force on the inclined arms, owing to the thickness of the material being bound, by moving the nut H up or down on the screw G, which resting against said lips, one of said pieces being between the face of the sewing-machine and the lower arm of the baster, and

the other piece being between the two arms of the baster. Now, as the feeding-power of the sewing-machine draws the material through the baster, the friction produced on the material by the arms inclined in a direction 0ppo site the movement of the material will automatically incline and direct each of the pieces of cloth separately and independently, and without lying in contact with each other, against the gaging-lips, by which the edges of said pieces of cloth are kept parallel to each other as they approach the needle for stitching. The regulating-spring allows a free perpendicular motion, or rising and falling, of the two arms, thus allowing any inequalities in the thickness of the material (such as seams) to pass through without disturbing in the least the working of the machine. If the friction of the arms upon the cloth be too great or too little, that can be regulated by loosening or tightening the adjusting-nut.

It will thus be seen that the time and trouble of basting by hand preparatory to using the sewing-machine (which time and trouble are frequently as great as the sewing itself are entirely saved.

When thebinder is to be used, loosen the fastening-nut of the binder and slide the hinding-lips forward till they protrude about half the width of the binding material. Then insert the binding into the lips of the binder so that one edge of said binding shall rest in each lip or hook, placing the edge of the cloth to be bound between the lips of the binder, it being first placed between the arms M M, and

, resting against the gaging-lips. Now, as the feedin g-power of the sewin g-machine draws the cloth and the binding toward the needle, and as the guide-arms M incline and direct the edge of the cloth against the gaging-lips and between the binding-lips, said binding-lips automatically lay the binding material about the edge of the cloth to be bound as perfectly as can be done by the hand and as rapidly as the sewing-machine can be worked.

Having thus described the structure and explained the use of the various parts of the automatic cloth-guide and binding-gage separately and in combination, and having also explained the manner of using the machine in combination with the sewing-machine, and some of the advantages and benefits resulting from such use, I proceed to remark, lastly, that I do not claim to have invented corrugated metallic base-plates, nor slots, nor upright posts, nor adjusting-screws, nor fastening or adjusting nuts, nor flat pieces of metal, here used, inclining the goods, nor metallic springs, which are here used to form the binding-lips and regulatin gsprin g, merely as such, and disconnectedly used; nor do I claim the use of any of the parts just named, except for the purposes herein set forth and as forming necessary and dependent parts of the machine in combination.

What I do claim as new, and of my own invention, and which I seek to secure by Letters Patent of the United States, is as follows:

1. The base-plate A, with its gaging-lips G 0, slot D, binder-slot E, upright post F, and screw G, in combination with the arms M M, binder J, and spring N, as and for the purposes specified.

2. The adjustable inclined arms M M, in their combination with the base-plate A, upright-post F, regulating-spring N, and binder J, as and for the purposes specified.

3. The seamless clamping-binder J, or its equivalent, with its regulating-nut I and separating-block K, in combination with the baseplate A and inclined arms M M, as and for the purposes specified.

4:. The regulating-spring N, orits equivalent, in combination with the inclined arms M M and binder J, all operating as and for the purposes specified.

L. T. OONANT.
