SPECIFICATION forming part of Letters Patent No. 552,160, dated December 31, 1.895. Application filed January 16, 1893. Serial No. 258,559. (No model.)

To @ZZ whom it may concern.-

Be it known that I, GEORGE lV. VEISS, of New York, in the county and State of New York, have invented a new and useful lmprovement in Sewing-Machines, of which the following is a specication.

My invention relates to an improvement in sewing-machines and more particularly in sewing-machines for stitching the binding on hat-brims.

Where the hat-brim is stiff and presents various sharp curves or irregularities, it has been found difiicult to run the line of stitching along such curves without disturbing the shape of the brim, giving it a permanent set out of shape. This difficulty has partly arisen from the fact that the work-table of the machine and that portion of the base of the machine upon which the work-table is supported have been so broad in the direction of the travel'of the work that it has required the irregular or curved portions of the work,where the curve is at an angle to the plane of the table, to be iiattened out to bring the brim down onto the table underneath theneedle, and this has strained the work so as to give it a permanent set out of shape.

The object of my present invention is to overcome the difficulty above recited by providing a machine of compact structure, having few parts and having the stitch-forming mechanism operating at the extreme outer end of the clothplate, which latter and the bed-plate are so disposed as to entirely cover and shield the looper and looper-shaft. The bed-'plate is also provided with a narrow extension or horn surmounted by a narrow curved cloth-plate.

By this construction it will be seen that a hat or other article to be operated upon may be stitched without forcing the same out of shape, and that neat clean work can be done and the stitches placed close to the edge of the article.

A practical embodiment of my invention is represented in the accompanying drawings, in which- Figure l is a view of the machine in vertical longitudinal section. Fig. 2 is an end view, the face-cap which covers the mechanism in the head of the overhanging arm being removed. Fig. 3 is a top plan view of the bedn plate, cloth-plate, and guide, the overhanging arm and part carried thereby being removed. Fig. 4L is a view in detail of the mechanism for producing the needle-feed. Fig. 5 is a view of the guide in detail in side elevation. Fig. G is a view of the same in longitudinal section; and Fig. 7 is a view in detail of the thread-holder, showing the same in top plan.

The bed of the machine in the vicinity of the uprising standard from which the overhanging arm extends is or 4may be of the usual breadth and is here denoted by A. As the bed-plate extends toward the needle, itis rapidly contracted into a narrow horn or extension A', which extends to a point near the path of the needle, sustaining thereon a narrow cloth-plate B,which is preferably rounded in the direction in which vthe work travels. The cloth-plate B projects beyond the end of the horn A across the path of the needle and is there provided with a suitable slot for the passage of the needle therethrough into proximity to a looper O,which is mounted underneath the narrow horn A' and extends to a point underneath the uprising standard D, where it is provided with bevel-gear o,which meshes with corresponding gear c on an upright shaft E. The upright shaft E is provided at its upper end with bevelgear el, which meshes with corresponding gear f on the drive-shaft F carrying the drive-pulley f and mounted in an overhanging arm G of the frame.

A box-head g is iixed to the free end of the overhanging arm G, and within said head the shaft F is provided with a cam-disk f2, on which is a crank-pin f3, which engages the needle-bar H to impart to it its verticallyre ciprocating movement. The swing of the needlebar to effect the feed is produced by a lever I adapted at one end to engage the camdisk f2 and at its opposite end connected with ICU ing eam-lever K in the usual manner. The needle 7L is removably secured to the needlebar H, as is usual, and is adapted to reciprocate and vibrate within the elongated slot b in the cloth-plate B.

A binder-guide L is removably secured to the top of the table B by means of screws Z extending through elongated slots l in the guide for regulating the distance of the guide toward and away from the path in which the work is to move. The guide has the usual folding jaws and loop Z2 and Z3 for laying the binding in the proper position to be stitched upon the opposite sides of the edge of the brim.

The narrow horn A of the bed-plate and the narrow cloth-plate supported thereon admit of adjusting the sharp curves of the brim to the cloth-plate without straining the curves sufficiently to distort them.

Vhat I claim is- In a sewing machine, the combination with the bed-plate having a lateral, narrow extension or horn, a bearing on said bed-plate and a bearing on the extreme outer end of said horn, a rotary shaft extending longitudinally of and shielded by said horn, journaled in said bearings and carrying alooper located in advance of said horn-bearing, of anarrow, transversely curved cloth-plate extending longitudinally of and carried by said horn, and having one end extending beyond the end of said horn and overhanging and shielding the looper, and a needle feed mechanism op* erating substantially at the extreme outer end of the cloth-plate and co-operating with the looper; substantially as described.
