FREDERICK J. THON AND HARRY GnWOLF, OF PHILADELPHIA, PENN- SYLVANIA, ASSIGNORS OF ONE-THIRD TO GEORGE M. GROSS, OF PHILADELPHIA, PENNSYLVANIA.

STITCH SEPARATING AND INDENTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 758,601, dated April 26, 1904.

Application filed June 13, 1903. Serial No- 161,332. (No model.)

To all 10720172, it ma n concern.-

Be it known thatwe, FREDERICK J. THON and HARRY G. WOLF, citizens of the United States, and residents of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have made a certain new and useful Invention in Stitch Separating and Indenting Machines; and we declare the followingto be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, referencebeing had to the accompanying drawings, and to letters and figures of reference marked thereon, which form apart of this specification.

Figure l is a side elevation of the invention. Fig. 3 is a detail View showing the gearing adapted for hand-power. Fig. 4; is a detail view, on a larger scale, of the two stitch-indenting rollers and their bearing-boxes and showing the antifriction-roller d. Fig. 5 is a detail View showing the upper toothed roller and its bearing-box in plan view. 'Fig. 6 is a detail view showing the cam d upon the lower shaft and antifriction-roller upon the upper shaft in side View. Fig. 7 is a detail view showing the formation of the front standard to allow the removal of the bearing-boxes therein. Fig. 8 is a sectional detail view'showing the pivotal connection of the upper rear bearingbox with the standard.

This invention has relation to stitch separating and indenting machines for the soles of boots and shoes, and has for its object the provision of an efiicient machine for this purpose of simple and comparatively inexpensive character, which will be applicable to any form of work and which may be dismantled without taking the main frame apart.

With this object in view the invention consists in the novel construction and combinations of parts, all as hereinafter described, and

pointed out in the appended claim.

Referring to the accompanying drawings, the letter A designates the main frame of the machine, which is designed to be mountedupon a table and consists of two parallel standards A, connected by longitudinal braces a, the standards having feet screwed to base A B B are upper and lower parallel shafts situated closely together and rotatably mounted in bearing-boxes b, fitting in guideways b of the standards of the main frame and carrying the upper toothed wheel 0 and the lower feed-roller G, having a smooth periphery, said wheels coacting upon the ShOGrSOlG for the end in view. In order to provide for separation of these two wheels G and C in inserting and removing the work from between the same, the rear bearing-box of the upper shaft is pivotally mounted in the frame, two transverse removable screw-bolts c entering seats 0 of said box and upon which the shaft turns as it is raised by the action ofcam-lever D, pivotally mounted upon the lower shaft B close by the forward standard A and having a cam-head 0Z working against an antifrictionroller 61 upon theupper shaft. A spiral spring Z, located between the top of the guideway of the forward standard and the upper forward bearing-box, and controlled in pressure by the screw Y, exerts pressure to force the two wheels G and 0 together.

-The bearing-boxes b are provided with lateral grooves bounded by end flanges 6 these boxes, which,with their shafts, are removable from the standards,being inserted in the guideways ?2 at their enlarged upper portions 6 and being lowered enter the contracted lower portions of the guideways, so that their end flanges will embrace the side walls of the guideways and the boxes be firmlyheld in place. The upper boxes 5 have the inner walls of their end flanges inclined or oblique, as shown at b", to admit of pivotal movement thereof without binding against the standards. The upper boxes '6 rest upon the lower bearing-boxes.

Referring now to the means for rotating the shafts, 1 l are small twin intermeshing spur gear -wheels mounted upon shafts B B and located just inside of the rear standard A, a large spur-gear 2 being carried by the lower of said shafts just outside of the rear standard and meshing with pinion 3 of spur-gear 4, said pinion and gear 4 having a removable bolt con nection with the main frame at 4c. The spurgear 4 meshes with spurgear 5 on shaft 6, carrying driving-pulley 7, a friction-clutch 8 being utilized to set the driving-pulley in motion through pedal connection 9.

The shaft 6 and its connections are mounted in detachable frame 10, bolted to the base A at 11 and to the rear standard at 12, the inner end of shaft 6 being removably seated in the rear standard at 6. By removing the bolts at 11 and 12 the frame 10 may be removed,with shaft 6, driving-pulley, frictionclutch, and spur-gear 5, for the purpose of converting the machine into a hand-operated device, a gear 13 with crank attachment 14 having its shaft inserted in seat 6 in lieu of gear 5.

The upper toothed indenting-wheel C is secured to its shaft by means of screws a passing through a collar 0 of said shaft. The lower wheel C is removable for the purpose of substituting a longer or shorter wheel for operating upon work having open or closed channels. The upper forward bearing-box has forwardlyprojecting flanges c laterally perforated for the attachment of the guard X.

By means of the transverse cam-lever D working close by the forward standard power is applied to separate wheels 0 U in a direct and positive manner, and inasmuch as only the shaft and its bearingboxes are raised a compartively slight power will accomplish it.

By means of the intermeshing spur gears 1 1, located upon the parallel shafts inside of the rear standard, the power for rotation of said shafts is applied in adirect manner, avoiding any lost motion, the two shafts being driven at the same rate of speed,which is most essential for the ends in view.

A pedal connection R may be provided for the transverse cam-lever D.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

In a stitch separating and indenting machine, the combination of the parallel standards having the guideways, the lower removable bearingboxes in said guideways, the upper removable bearing boxes in said guideways resting upon the lower bearing-boxes, the upper and lower parallel shafts in said bearingboxes situated closely together, the stitch-indenting and feed wheels upon said shafts, the uniform intermeshing spur gear-wheels upon said shafts, and a transverse cam-lever pivoted upon the lower shaft, and adapted to engage the upper shaft to raise the same, substantially as specified.

In testimony whereof we affix our signatures in presence of two witnesses.
