`IMPROVEMENTIN CLOTH-GUIDES FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 48,369, dated June 27, 1865.

To all whom it may concern.-

Beit known that I, GEO. F. GLEMoNs, of Springfield, Hampden county, Commonwealth of Massachusetts, have invented a new and useful Attachment to Sewing-Machines; and Ido 'hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to letters of reference marked thereon.

The object of my invention is to obtain an adjustable cloth-guide, by means of which the machine is made as near self-operating as practicable, and so 'arranged as to vbe equally adaptable to any kind of sewingmachine now ,in use, and when applied perfectly adjustable to suit every variety of work usually required of such machines.

` In sewing-machines as ordinarily construct- 1 ed it is necessary to guide the cloth with one hand, while the other takes it from theqi'eed; but with my invention applied it is only necessary to set the guide as desired, and it keeps the cloth in the same position until altered.

I will now describe my invention.

In the drawings, Figure Vl is a plan view,

i and Fig. 2 a side view, of abcd-plate of a sewing-machine with my invention attached in two different forms, as shown at Aand B.

I will describe it first as shown at A. In this th'e part C is the guide used in nearly all machines, against which the cloth is inclined, and, running alongJ the edge is kept equally distant from the needle. To the top of this a link, a, Ais secured by the screw b. This link` is slotted to admit ot' its being adjusted. To this link the spring E is riveted at d, on which it turns. This spring, it will be seen, passes out, turns downward, and passes back over the cloth, on which it is .designed to have a i nearly-equal" pressure, which is obtained in this way: The lower part, f, ot' the spring E has a curve in it when not screwed to the plate,

i assshown iuFig. 3, being highest in the middle and lower at each end, but so arranged that the end g touches the bed-piece rst, and

the force required tostraighten the spring and bring it at on the cloth produces an equal pressnreon the end g as at h. Otherwise, if

1 this was not arrangedin this way, much greater pressure would be the result at h than g, which isnot desired.

Most sewing-machines are provided with a cloth-guide likethe piece marked C, in which case, instead of providing an extra piece, O, with my device attached for guiding the cloth as shown in diagram A, IV furnish them as represented in diagram B, where my improved devices are shown as attached to a thin plate, G, which can be fitted over the common guidepiece O when desired, and secured thereto and to the bed-plate by the screw 7c, passing through the slots F and F.

'The operation is as follows: 'The part C being adjusted and secured by means of the slot F and screw lc so that the side m shall be the same distance from the needle that is required to make the seam from the edges ot' the cloth, the spring E is ttirned so that the corner a shall strike against O, thus making it at an angle less than a right angle with the direction of the cloth on one side or the other, accordingly as the cloth runs from let't to rightlor right to let't, as machines diii'er in this respect, and the cloth, in itspassage pressing against the edge of the spring, is inclined up against O by this inclined edge ot the spring, and is prevented from getting between the end of the spring and C by the spring being turned, as before mentioned, so as to touch C at a.

The angle at which the springis turned may vary with the width and quality of the fabric worked on, so,also, may the stiffness of-the spring, which may be increased or diminished byturning 0n or olif the piece H, as desired.

It will readily be seen that all the parts are encuen r. cLnMoNs.
