ATENT Fries.

MASSACHUSETTS, ASSIGNOR TO THE RAND-'TRIMMING AND STITCH-RUBBING MACHINE.

SPECIFICATION forming part of Letters Patent No. 632,084, dated August 29, 1899.

Application filed February 23, 1899- Serial No. 706,565. (No model.)

To ctZZ whom it may concern.-

Be it known that I, EDWIN E. ANGELL, of Somerville, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Rand-Trimmers and Stitch-Rubbing Machines, of which the following is a specification.

This invention relates to a rotary randtrimmer and stitch-rubbing machine of the character described and shown in the patents to E. F. Maxwell, No. 561,017, dated May 26, 1896; No. 549,676, dated November 12, 1895,. and No. 567,246, dated September 8, 1896.

The object of this invention is to mount on the same shaft rand-trimming and stitchrubbing devicesin a practical and permanent manner.

My invention consists of certain novel features hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, which illustrate a construction embodying my invention, Figure 1 is a side View of a portion of a shoetrimming machine and showing the stitchrubber and rand-trimmer in their proper positions. Fig. 2 is a sectional view through the rand-trimmer and stitch-rubber and showing the manner of mounting the same upon the revolving shaft. Fig. 3 is aplan View of the rand-trimmer shield. Fig. 4 is a sectional view through the rand-trimmer shield on the line XX, Fig. 3. Fig. 5 is aplan view of the stitch-rubber shield. Fig. 6 is a side view of the stitch-rubber shield. Fig. 7 is a side view of the stitch-rubber. Fig. 8 is a plan view of the stitch-rubber. Fig. 9 is a. plan View of the rand-trimmer, looking from the shield side. Fig. 10 is a sectional view through the rand-trimmer on the line X X, Fig. 9. Fig. 11 is a sectional view of the bushing on which the stitch-rubber shield is mounted and which also centers the rand-trimmer at the opposite end.

Like letters of reference refer to like parts throughout the several views.

A represents a portion of the usual supporting-frame of a trimming-machine, which at its upper end A carries a hollow bearing A The shaft B, which is mounted in said bearing, is of the construction shown in the patent to Ambrose S. Vose, dated April 23,

1895, No. 538,055. The extension B of the shaftB is of smaller diameter than said shaft,

ner end the reduced extension D, which fits around the shaft and contacts with the stitchrubber, as shown in Fig. 2. Around the extension D of the bushing D is freely mounted the stitch-rubber shield E, and the object of loosely mounting this shield on the extension D of the bushing D is to prevent its rotation when the work is being operated on by the stitch-rubber, except as it is rotated by the work, thus preventing injury to the upper of the boot or shoe. The extension D of the bushing D bears against the stitch-rubber C and holds it tightly against the shaft B, so that it rotates with said shaft. The steel ring F is located in a recess on the inner side of the stitch-rubber and projects slightly above the surface of said rubber for the purpose of preventing the contact of the stitchrubber with the stitch-rubber shield. When the work is placed on the machine, the stitchrubber and the stitch rubber shield are pinched together between the upper and the edge of the sole of the boot or shoe, and the ring F provides a friction-surface for the stitch-rubber shield, and this arrangement is preferable to having the stitch-rubber shield in contact with the entire inner surface of the stitch-rubber, because in the latter case there would be too much friction between the shield and the rubber, and the shield would revolve with the stitch-rubber and mar the upper of the shoe -in the operation of the machine. The stitch-rubber shield being of hardened metal and the stitch-rubber being of soft metal if said hardened ring F were not in the stitch-rubber, as shown, but if the projection were made solid with the rubber and of the same metal the said shield would in a short time wear away the projection on the stitchrubber, which is provided to lessen the friction between the two parts. Thebushing D extends beyond the outer end of the exten sion B of the shaft B, as shown in Fig. 2, and the cutter G is provided with an annular lip G, which fits into the bushing D, as shown in Fig. 2, and by this arrangement the cutter is accurately centered on the shaft, the cutter being of course secured to the shaft by the screw H, with the head 11 in the opening H of the rand-trimmer and the head H in the opening H of the rand-trimmer shield I, which is loosely mounted on said head H and the head II of the screw rests upon the outer edge of the shield, as shown in Fig. 2. \Vhen the parts are connected up, the lip I of the randtrimmer shield I projects over the edge of the rand-trimmer a proper distance to protect the upper.

I do not limit myself to the arrangement and construction shown, as the same may be varied without departing from the spirit of my invention.

Having thus ascertained the nature of my invention and set forth a construction embodying the same, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. In an apparatus of the class described, a shaft having a reduced extension, a stitchrubber mounted on said extension and bearing against the main portion of the axle, a bushing placed on said extension and bearing against said rubber and having an annular recess formed in its outer periphery at its inner end, a shield loosely journaled on said bushing in said annular recess, and means for holding said bushing in place on said extension.

2. In an apparatus of the class described, a shaft having a reduced extension, a stitchrubber mounted on said extension and bearing against the main portion of the axle, a bushing placed on said extension and bearing against said rubber and having an annular recess in its outer periphery at its inner end and projecting at its outer end beyond said extension, a shield loosely journaled on said bushing and in said annular recess, a ring interposed between said rubberand said shield, a screw turned into the outer end of said extension and having two bearings of dilferent diameters, a cutter mounted on the innerone of said bearings and'abutting the outer end of said bushing, and ashield mounted on the other of said bearings.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 15th day of February, A. D. 1899.
