DANIEL A. SUTHERLAND, OF LYNN, MASSACHUSETTS, ASSIGNOR TO THE SUTHERLAND CORRUGATED SEAM COMPANY, OF NASHUA, NEIV HAMP- SHIRE.

MACHINE FOR CORRUGATING SEAMS.

SPECIFICATION forming part of Letters Patent NO. 371,527, dated October 11, 1887.

Application tiled March 7, 1887. Serial No. 230,065.

To all whom it may canoe/7n:

Be it known that I, DANIEL A. SUTHERLAND, of Lynn, in the county of Essex and Commonwealth of Massachusetts, have invented certain Improvements in Machines for Corrugating Seams, of which the following, taken in connection with the accompanying drawings, is a specification.

This invention relates to means for corrugating seams; and the nature thereof is fully described and specifically claimed hereinafter.

Referring to the drawings, Figurel is aside elevation of the machine embodying my invention. The view is made partlyin section to better illustrate details of construction. Fig. 2 is an elevation of the front of the machine. Fig. 3 is a plan ofasection on line 00 09. Fig. 6 is a plan ofa section on line yy. Fig. 5is a detached view of the lower section ofthe feed-foot. Fig. 4 is a similar view of the lower part of the guide-foot. Figs. 7 and 8 are views of details to be referred to hereinafter.

The frame-work ofthe machine is designated in the drawings by the letters A A A. Said frame is provided with a hole or socket to re ceive the plunger B, as shown fully in Fig. 1. The plunger is formed with a square part or section, B, that enters into asimilar cavity in the frame A, as shown, and thus prevents the plunger from turning round in its socket. The plunger also carries on its top end a suitable head, O,in which is mounted the wheel D, and the plunger-rod permits vertical movement in its socket to liftand depress the wheel under the action of the hammer. The upward movement ofthe plunger is effected by a spring, F, which bears its bottom end upon the bolt H and with its opposite end lifts upward the plunger, as shown. The upward movement ofthe plunger is limited by the bolts K K. In the bottom end of the plunger isa rod, M,that extends down through the bolt H and serves as a means to lay hold of and pull the plunger downward whenever occasion requires. If desired,a suitable connection may be attached to the rod M and extended downward, so as to be engaged by the foot of the operator. The bolt H may be turned and forced upward or downward, as occasion requires it, to increase and guidefoot.

diminish the torsion of spring F, and on the bolt is a check-nut, N, to be operated by handle I? and forced upward or downward to clamp and hold the machine onto its support- 5 ing bench or table. (Not shown.)

The wheel D is provided with duplex groove a a and intermediate fin, b, and permits revolving movement on its axis or supporting-pin cl. Above the wheel is a hammer, e. The ham- 6o mer rod or shank is fitted to slide vertically in a suitable hole or socket in the frame A, as shown, and the top end of the hammer-rod is connected with and moved up and down by a cam, f, fixed on the main driving-shaft T. Directlyin rear of the ham mer-headis a guidefoot, 121.. This foot is particularly represented in Figs. 4 and 8. The spindle or shank of the foot is adapted to a suitable hole in the frame A, (see Fig. 1,) and is surrounded by a spiral 7o spring, a, which spring abuts one end against the bolt t and forces downward the guide-foot, to which end the foot permits slight vertical movement. The downward movement of the foot is limited by the pin 24. Under the foot m is a plate, 20, supported by the head 0 and set edgewisc to the foot,as shown. This guide fin enters the seam-crease, as represented in Fig. 8, and thusassists the foot m to hold and guide forward the material.

In operation the work is placed face downward upon the wheel D, the fin b lying in between the seam crease. The edges of the united material extend upward toward the hammer c and are supported by the guide-foot m. This foot extends forward close up to the hammer, so that the hammer strikes downward the material immediately asitleaves the The material is forced downward by the hammer and crowded into the grooves 0 a a, and thus are produced corrugations conforming to the grooves a a. This seam formed and stayed has been heretofore patented to me by Letters Patent of the United States. The

sides 4 4 of the guide-foot are made of spring 5 metal, so as to open laterally and receive the edges of the seam, as shown in Fig. 8, and also to close tightly against the material while passing through. The fin-guide 2O enters the seamcrease under the guide-foot, as in Fig. 8, and thus cooperates to hold the seam in position to go onto the wheel and under the hammer. The wheel'D yields under the hammer by reason df-thespring F, and the material is thus prevented from being injured by the hammer. The blow of the hammer is first expended on the edges of thc material sufficiently to compress and set the corrugations. It'then passes into the wheel D and spring F, all in a quite .obvious manner. The material is moved forward by the presser-feed foot 6, little at a time,

- t0 the end that the hammer shall strike but a small portion of the material at once. Said foot is composed of two parts or sections. The

part 6, or foot proper, (see Fig. 5,) hasitsshank socketed in a'suitable hole in therod or section 7, and it is surrounded by a spring, 8, that operates to push the foot downward, and so determine the pressure of the foot upon the material. On the top of section 6 are nuts 9 and 10, by which the foot may be adjusted higheror lower, as occasion demands. The top end of the rod or section 7 is connected by means of cam eccentric 12 with the main driving-shaft, and a movement is thus imparted to the rod which causes it to rock on the pin 14, and so lift, depress, and move forward the foot, and consequently the material, all in an obvious manner. The pin 14 permits adjustment to vary the length of the stroke or forward movement of the foot, and consequently regulate the speed with which the material goes forward under the hammer.

I claim- 1. In a machine for corrugating scams, the combination of the support for the'material, having duplex grooves and intermediate fin, I), and mechanism, substantially as described, for compressing and setting the material down into said grooves, substantially as described.

2. In a machine for corrugating seams, the combination of the support for the material, having duplex grooves a a and the intermedi ate fin, b, and a pounding mechanism, substantially as described, adapted to strike positive blows upon the material and crowd it into the grooves, substantially as described.

combination of the support for the material,

having duplex grooves a a, the intermediate fin, b, and adapted to yield, substantially as described, and a pounding mechanism adapted to strike upon the material and compress it into the grooves, substantially as set forth.

4. In a machine for corrugating seams, and of substantially the construction described, the combination of the plunger, the supporting-spring, the wheel D, and the pounder mechanism, substantially as described.

5. In a machine for corrugating seams, the combination of the support for the material, having grooves, as set forth, a pounder mech anis'm, and the independent presser-feed foot adapted to move forward the material, as described.

6. In a machine for corrugating seams, the support for the material, having duplex grooves a a and the intermediate fin, b, combined with the seam-crease guide 20, arranged in line with said fin b, substantially as de scribed.

7. In combination, in a seam-finishing machine, the support, as D, the finishing mechanism, as e, and the guide 20, supported be DANIEL A. I SUTHERLAND.
