UNITED STATES PATENT ()FFIC'EQ AUGUST HABBERT, OF NEW YORK, N. Y.

SEWING-MACHINE GUIDE.

SPECIFICATION forming part of Letters Patent No. 269,049, dated December 12, 1882.

' Application filed October 3, 188 2. (No model.)

To all whom it may concern Be it known that I, AUGUST HABBERT, a citizen of the German Empire, residing at New York, in the county and State of New York, have invented new and useful Improvements in Sewing-Machine Guides, ofv which the following is a specification.

This invention relates to a sewing-machine guide which is provided with a series of recesses at determined distances apart, and with a latch constructed to engage with said recesses, so that by changing the latch from one recess to another the guide can be adjusted instantaneously and correctly to any desired point, and much time and labor are saved.

The peculiar construction of my guide is pointed out in the following specificatiomand illustrated in the accompanying drawings, in which- Figure 1 represents a longitudinal vertical sectionin the plane mm, Fig. 2. Fig. 2 is a plan or top view. Fig. 3 is a longitudinal vertical section of a modification in the plane 3 12 Fig. 4. Fig. 4 is a plan or top view of the same.

Similar letters indicate corresponding parts.

In the accompanying drawings, the letter A designates the plate which supports the guide B, the shank a of said guide .being fitted into staples b b, which are firmly secured to plate A, so that when this plate is fastened in the required position upon the cloth-plate of a sewing-machine the guide can be moved toward and from the needle. The shank a is, by preference, made in two parts, one of which slides in a recess formed in the other, and is secured in the required position, so that the shank can be shortened or lengthened in order to obtain the required range in adjusting the guide. In the example shown in Figs. 1 and 2 the shank a of the guide is provided with a series of recesses or cavities, c, at determined distances apart, and the staples b b are connected by a yoke, 01, through which extends a pin, 0, which is exposed to the action of a spring, f, so that when it is free to follow this action it is depressed and caused to engage with one of the recesses c. Said pin therefore forms a latch which looks the guide in any position into which it may be brought. In the example shown in the drawings the recesses c are at lel seams at equal distances apart. If the first seam has been completed, the latch c is raised and the guide is moved until the latch ongages with the next recess, and then the second seam is completed, and so on.

By means of the latch and the recesses, the guide can be adjusted instantaneously, and the distances between the successive seams are absolutely fixed by the distances between the successive recesses, and they must necessarily become uniform if the distances. between the recesses are uniform.

Heretofore a sewing-gage for sewing-machines has been adjusted-by'means of a pivoted lever adapted to swing, and provided with a spur for engaging any one of a series of notches arranged on a base-plate; but such is not claimed by me, and differs from my invention in that I arrange the recesses in the same right line with relation to each other in a longitudinal plane, and the locking-latch is fixed, except as to capability of moving in a vertical plane, by which arrangement the latch is always in position to quickly engage the recesses, and the provision of pivots is avoided. In the example shown in Figs. 1 and 2the recesses 0 move with the guide, while :the latch retains its position. In the example shown in Figs. 3 and 4 the recesses remain stationary, while the latch moves with the guide. In these figures the letter 6* represents the latch, which is made in the form of a hook depending from a fiat spring, f which issecured to the shank a of the guide B. The recesses 0* are formed in the edge of a blade or bar which is firmly secured to one of the staples b. ]By taking hold of the end of the springfi, the latch 0* can be raised and the guide can he moved in or out until the latch engages with the next or any subsequent recess.

What I claim as new, and desire to secure by Letters Patent, is-

1. A guide for sewing-machines, consisting of a base-plate, A, provided with staples b,the guide B, adapted to slide in the staples, the series of recesses arranged in the same right line with relation to each other in a [longitudinal plane, and a spring, f, carrying a latch which is fixed except as to capability of moving in a vertical plane, substantially as described.

-2. The combination, substantially as hereinbefore described, of the guide B, the recesses- 5 0, formed. in the shank of the guide, the yoke (1, connecting the staples in which said shank moves, and the spring-latch e, fitted in said yoke.

In testimony whereof I have hereunto set my I hand and seal in thepresence of two subscrib- 10 I ing witnesses.
