To all whom it may concern:

Be it known that I, SAMUEL YEANEY STooK- and useful Improvements in Welt-Cutting Machines; and I do declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in machines for cutting leather or other'm'aterial into welts or strips for use in the manufacture of gloves, mittens, pocket-books, and other leather goods. I w

The object of the present invention is to provide a machine of this character which will vention consists of certain novel features of be simple in construction,-durable in use, efiicient in operation, and comparatively inexpensive to produce.

With this and other objects in view the inconstruction, combination, and arrangement of parts, as will be more fully described, and particularly pointed out in the appended claims. I

In the accompanying drawings, Figure 1 is a side elevation of the improved machine.

Fig. 2 is a top plan view of the same, a ,portion of the machine and the leather upon the machine being broken away to show the cutting apparatus. Fig. 3 is a Vertical longitudinal section through the machine. Fig. 4 is a vertical transverse section taken on the line 00 w of Fig. 3.

In the embodiment of the invention illustrated in the drawings the numeral 1 denotes a suitable frame or support having journaled transversely at one end a roller 2, upon which the continuous web or sheet of leather or other material A, to be cut into welts or strips, is wound. From the said roll 2 the leather A passes up over a guide-roller 4, journaled.

ber of said cutting-disks may be provided, they maybe spaced any distance apart, ac-" cording to the number and size of the welts into which it-is' desired to cut the sheet of leather. The cutting of the leather is eflected' by the tension exerted upon the same' as it is; 1 passed around the cutter, and. this tension is' 1 produced by providing combined guide and" tension rollers 9 and 10 for theleather before it passes to the cutter anda series or group 11 of guide and tension rollers after it has been cut into welts or'stripsB by thecutter. Tli'e rollers 9 and 10 are" transversely disposed across the frame above and in rear of the cutter, and they are journaled in inclined uprights 12, secured upon each side of the frame.

The web or sheet A of leather after leaving the roller t passes under the roller 9, then up over and around the roller 10, and then around the cutter, as seen in Fig. 3. In .order to more effectively hold the leather against the cutter while it is being cut, a spring-plate 13, secured upon a cross-bar 14;, is adapted to bear upon the leather slightly above the cutter, as shown, and in order to prevent the leather from shifting sidewise a comb-bar 15 is secured transverselyto the frame on each side of the cutter. The teeth 16 of thesecombs project between the cutting-disks 7 to hold the leather againsttransverse movement, as will be readily understood. The group 11 of transverselydisposed rollers between which the welts B are passed after being formed by the cutter comroller 18, and two idler tension-rollers 19 and 20, one of the latter being disposed on each side of the positively-driven roller 18. The welts B pass between these rollers, as shown in Fig. 8, and then between one or more groups 21 of separating-rollers. Each one of said groups 21 separates one welt or strip B from the body of welts or strips and consists of a positivelydriven roller 22 with one tension-roller 23 upon each of its sides. It will be understood that as many of these groups 21 are provided as. the number of welts into which it is desired to cut the leather.

In order to drive the cutter, a main shaft prises a guide-roller 17, a positively-driven tion of the frame 1, and said shaft is geared to the cutter-shaft 6 in any suitable manner, but preferably by an endless belt 26, which is passed about pulleys 27, secured upon said shafts 26 and 6. In order to drive thevarious other rollers, a transverse shaft 28 is provided and geared to the shaft 25 by a belt 29, passed about pulleys 30, secured to said shafts 25 and 28. The roller 18 is driven by a belt 31, passed about pulleys 32, secured to the shaft 28 and the shaft of the roller 18. shafts ofeach two adjacent rollers 22 are geared together by belts 33, passed about suitable pulleys 34C, and the shaft of the innermost roller 22 is geared to the shaft 28 by a belt 35, which is passed .around pulleys 36, secured to said shafts, as clearly shown in Figs. 1 and 2.

The operation and advantages of the invention will be readily understood from the foregoing description, taken in connection with the accompanying drawings. It will be seen that when the sheet or web of leather is properly placed in the machine, as in Fig. 3, and motion is imparted to the main drive-shaft 25 the cutter and the various rollers will be set in motion through the belt-gearing previously described. The machine may be constructed to cut any number and any size of welts and will work equally well on all kinds, weights, and grades of leather. Owing to the capacity of the machine and the fact that it may be operated by one man, a great saving in time and labor is effected by its use.

It will be understood that various changes in the form, proportion, and the minor details The of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. A welt-cutting machine comprising tension-rollers, a positively-driven roller having a plurality of rotary cutters, spaced apart, means to draw the welts cut by the cutters .from the said roller, said means including a positively-driven roller and tension-rollers coacting therewith, and delivery means for the several welts. each of said delivery means including a positively-driven roller and a tension-roller coacting therewith, substantially as described.

2. In a machine of the character described, the combination of a suitable frame, a rotary cutter mounted thereon, tension-rollers adapted to guide the material to be cut, to and from said rotary cutter, a spring adapted to hold said material upon said rotary cutter, and a comb-bar eoacting with said rotary cutter to prevent transverse movement of the material upon the said rotary cutter, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
