MACHINE FOR SEWING AND BEATING OUT SEAMS..

SPECIFICATION forming part of Letters Patent No. 449,101, dated March 31, 1891.

Application filed April 11, 1890. Renewed January 29, I891. Serial No. 379,483- (No model.)

To all whom it may concern:

Be it known that I, EDWARD B. ALLEN, of Portland, county of Cumberland, State of Maine, have invented an Improvement in Machines for Sewing and Beating Out Seams, of which thefollowing description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

It is well understood in boot and shoe work that the seams are closed with the faces of the material in contact, and that the seam is thereafter beaten or hammered, so that when the material is laid out fiat an objectionable ridge will not appear. This beating out of the seam, as it is called, has been done both by hand and by seam rubbing or beating machines, upon which the leather properly stitched together is placed.

The object of my invention is the production of a sewing-machine having a hammen ing or beating-out device to hammer or beat out the seam just after the leather or other material is stitched together.

My invention consists, therefore, essentially, in the combination, with stitch-forming mechanism, of a beating-out device consisting, as herein shown, of a spring-acted hammer, substantially as will be described.

Figure 1 in side elevation represents a sewing-machine with my improvements added thereto; Fig. 2, a view thereof below the irregular dotted line w 00. Fig. 3 is adetail showing some of the devices with two pieces of leather applied thereto as they will be in practice. Fig. at is a detail showing one end of the guide and part of the connected moistening device; Fig. 5, a detail showing the face of the anvil, which also serves as a separator; and Fig. 6, a face view of the cam employed to actuate the beating-out device.

The frame-work A, the rotating shaft A, having a hook A at its front end, the presserbar A the presser-foot A the needle-bar A only the upper end of which is shown, the

eye-pointed needle a, (shown in section in Fig. 2,) and the needle-bar-actuating arm A and the link A are common to the so-called Willcox & Gibbssewing-machine, the said machine in practice having a suitable fourmotion feeding device to engage and move the material B after each stitch.

I have selected this well-known form of machine With which to illustrate my invention; but I desire it to be understood that instead of the particular machine herein shown and the particular stitch-forming mechanism I may employ any other suitable well-known stitch-forming mechanism.

In embodying myinvention I have shaped the cloth-plate B substantially as shown in Fig. 2, and I have connected to the table or bed B, on which the sewing-machine stands, a bearing B in which I have secured the shank 2 of an arm or horn O, to the forward end of which by a screw 3 I have secured a plate 0', the part b of which forms an anvil, while the broader part b forms a separator, the said anvil and separator standing between the two pieces of material B B, which are to be stitched together near their edges, the faces of the two pieces of material being turned together. Fig. 5 shows the face edge of this plate.

The cloth-plate B has applied to it a gage D, arranged at the front of the machine or between the needle-hole and the operator to gage the edges of the material to be stitched, and at the rear of the needle-hole and needle I have secured to the cloth-plate a suitable guide, as E, which is made adjustable by a suitable set-screw E. The forward end of this guide is recessed, as best shown in Fig. 4, to receive the edges of the material after the two thicknesses thereof have been stitched together, and in order to assist in beating out the seam I have applied to the machine moistening mechanism, herein represented as a cup G to contain water or other fluid, a pipe G leading therefrom to the end of the said guide E, the said tube preferably being filled with a suitable wick, as represented at 5, so as to deliver the water or moistening-fiuid slowly in contact with the edges to be beaten out.

The main or hook shaft of the machine is provided with a cam 19 to act upon a cross piece or block I), having a toe 8 and having a hole or notch at one end to embrace and be guided by the said main or hook shaft, the

said block having secured to it by a set-screw 10 the shank of a hammer or heater d, surrounded by a suitable spring 12, which normally acts to keep the toe 8 against the said cam, the cam having an abrupt shoulder 13, off from which the toe will drop quickly once during each rotation of the cam, the hammer or beater being thrown forward quickly by the spring 12, which is compressed, while the hammer or beater is retracted.

It will be understood from the foregoing description that the material will have its edges stitched together, and at a short distance beyond the needlehole the edges will be moistened and thereafter hammered or beaten out, so that the united material will be taken from the machine with its edges sewed together and beaten out ready to be laid out flat and not present an objectionable ridge outside the line of seam.
