IMPROVED WELTED-SEAM-FINISHING- OR REDUCING- MACHINE The Schedule referred to in these Letters Patent and making part of the sama.

.Iov all persons to whom these presents shall come:

Be it known that I, JOHN H. COLE, of NorthfBridgewater, in the county of Plymouth, and State of Massachusetts, have invented a new and useful Welted-Seam- Finishing, or Reducing Machine; and do hereby declare thesame to be fully described in the following specification, and represented in the accompanying drawings, of which-` Figure 1 is a top view; Y

Figure 2, a longitudinal section Figure 3, a front levation;

Figure 4, a transverse section; and

Figure 5, an'under-side view of such machine.

The purpose of the machine is to trim, or remove from the welt of a Welted seam, the surplus leather, and flatten, or press down the joined parts on each side of the welt, and close to the latter. Also, to trim, or even the edges of the said parts and welt.

In the drawingsl A denotes a frame,r or table, provided with an arm, or standard, B, extending above and over it, in manner as represented. y

This arm, at or near its upper end, supports the axle, or journals of a pressing-wheel, O.

Underneath the wheel G, and projecting up through the top of the frame, is a feeding-wheel, D, whose shaft, K, is supported in a lever, E, arranged below the tabletop, and pivoted to the table, as shown at a a.

A weight, applied to a rod hung o n the rear end of the said lever, serves to pressV the feed-wheel toward the wheel O.

The said feed-wheel D has a groove, b, formed in it, at and around the middle of its periphery, the said periphery being bevelled on each side of the groove, in manner as shown in iig. 4. 4

Each bevelled surface c c is provided with teeth, cut in it, and in form are analogous to those of a file.

The periphery of the pressing-Whoo. C is also bevoiled, in reverse of that of the feed-wheel D, as shown at d d, and also is grooved, as shown at e, the groove runnin-g around such periphery.

In rear of the said wheels, and extending between them, in manner as represented in iig. 2, is a welttrimming furcated knife, E, it being formed as represented in the drawings, and particularly as shown in Figure 6, which is a topview of it.

The base, c, ofthe opening between the prongs ff of the knife, is a cutter, or has a chisel-edge, which is arranged in a vertical plane, passing through the grooves of the wheels C and D.

In advance of the said wheels, and arranged in other respects with them, in manner as represented, are two Y stationary guides, F G, which are grooved, as shown at g h, so as to receive the welt, and the edges of the pieces of leather sewed to it, and direct the said parts properly to the grooves of the feed and pressing-wheels D.

A knife, or chisel, H, arranged in manner as represented, serves to dress, or trim the lower edges of the welt, and parts, or pieces of leather sewed to it.

lhis knife is fixed to the lower grooveguide, G, and extends obliquely across its groove.

In rear of the knife is a gauge-spring, d2, which has, screwed upward into the guide G, a screw, b2, that serves to regulate thev distance to which the spring may be depressed. The spring and its screw thus answer to gauge the thickness of shaving to be removed by the knife.

Furthermore, the gauge G is adjustable vertically, that is, it has slots, o2 o2, made through it, to receive clamp-screws, dz d2,whicl1 screw into the table, or frame of the machine.

In Figure 7 is represented a transverse section of a welted seam, as it is preparatory to being introduced into the machine for being trimmed and pressed by it.

Figure 8, a similar section of it, after it is trimmed, and pressed, or finished.

In such figs. 7 and 8, the welt is shown at w, the two portions, or pieces of leather `sewed to the welt, being shown at x x.

The upper of the knives trims the Welt down to the red line, z, and the lower knife trims up to the line o, the lower edges, or parts ofthe welt, and those of the pieces sewed to the welt.

A crank, I, fixed on the end 'of the shaft K of the feed-wheel D, serves to enable a person to revolvcthe feed-wheel. v By introducing a welted seam between the guides, with the welt within their grooves g h, and pressing it forward between the feed and pressing-wheels O D,

and revolving' the feed-wheel, the sewed part will be drawn through the machine by the action of the feedwheel; the 'surplus of the welt, and the edges of the leather parts sewed/to it, being trimmed in the m'cantime by the knives; andthe parts scwed to the welts will also be pressed out laterally, in directions from the welt, the bevelled surfaces of the wheels O D operating to draw out and so press the said parts.

This machine is of much utility for trimming the welts and` edges of the leather used'in makingsideseams of boot-legs, or the back, or heel-seams of shoes.

In the said machine, I claim, as my invention, the following; that is to say- I claim the combination, as well as the arrangement, of the peripheral-grooved feed-wheel D, the peripheralgrooved, or pressing-wheel O, the two slotted, or grooved guides F G, and the welt-cutter E, the whole being to opcrate together substantially as specified.

Also, the combination and arrangement of the insideedge trimming-knife H, with the peripberal-grooved feed-wheel, the peripheral-grooved, or pressingfwheel, the slotted guides, and the welt-cutter, arranged and applied so as to operate together, as specified.

Also, the fe'ed and smoothing-wheels,vas'made, not only with the welt-receiving grooves, extending around their peripheries, but with the arrangement, as described, ot' bevelled surfaces on opposite sides'of the said grooves, such being for stretching the leather laterally from the Welt, as set forth.

Also, the combination and arrangement of the gauge a2, and the adjusting-screw b2, with the gauge G and the knife H, combined with the guide F, the feeding and pressing-wheels C D, and the knife E, arranged to operate as set forth.

Also, the application of the guide G and the knife H to the frame, so as toy be adjustable vertically with respect to the feed-wheel, as may be necessary to adapt the machine to operate on leather of any particular thickness.
