E. L. KEENER SHOE HEEL CUTTER GUARD Filed Aug. 26, 192-7 i lil l l l Patented Dec. 25, 1928.
UNITED STATES ERNEST L. KEENER, OF NEWCASTLE, INDIANA.
SHOE-I-IEEL-CUTTER. GUARD.
Application filed August 26, 1927. Serial No. 215,547.
This invention relates to improvements in cutter heads which are especially designed for trimming the lifts on the'heels of shoes. In the cutter heads heretofore used, the outside disk which aids the holding the knife member in place and which contacts the heel to regulate the depth of the out, frequently disfigures the heel by wearing a channel in it, and it is the object of this invention so to mount the diskthat it will contact the heel with a rolling movement quite independent of the rapid rotation of the cutting knives.
I accomplish this object and other minor ones which will hereinafter appear, by the means illustrated in the accompanying drawing, in which- Fig. 1, is a side view of a cutter head embodying my invention, and
Fig. 2, is a longitudinal section on the line 22 of Fig. 1.
Referring more particularly to Fig. 2, the cutter head is mounted on a shaft 3 which is supported and driven in any usual and suitable manner, not shown. The end is reduced to form a toe 4 and entering through the latter is a threaded bore in which a shaft extension 5 is screwed.
Mounted on the shaft 3 is a sleeve 6 having a disk 7 with a depression on its outer side forming a seat for a disk 8 the circumference of which has a series of cutters 9. On the side of the disk 8, next to the disk 7, is an annular flange which has oblique cutters 10. The cutters are somewhat protected by the extension of the recessed disk 7. The disk 8 has a hub 11 which is seated in a corresponding socket formed in the sleeve 6.
A disk 12 has a hub 13, which enters the bore of disk 8, and on the opposite or other side is a reduced hub extension 14. The disk 12 and its hubs are formed integrally with the shaft extension 5. The outer end of shaft extension 5 has a left-hand thread on which a nut 15 is screwed. The end 16 of shaft extension 5 is squared to receive a wrench in screwing the member 5 into shaft 3, and it will be noted in my construction that the cutting disk 8 is retained by disk 12 and nut 15 on shaft extension 5, and not entirely by a disk 17. A principal function of the disk 17 is for its periphery to contact the work, the shoe heel, which is trimmed and shaped by the cutters 9 and 10, and to keep it from Wearing the heel by rotation against it, and marring it by making a channel, I mount it on the hub extension 14 to rotate independently of the rate of travel of the cutters, and to insure greater freedom of movement I prefer to mount it on hearing balls 18. To this end I provide a race-member 19 which is locked on hub-extension 14, by thenut 15; also, a race-member 20, which is mounted in a fixed manner in the bore of disk 17 and is locked against movement of translation by the balls 18.
In the operation of my invention, the heel of a shoe having lifts to be trimmed and evened is fed against the rotating cutters and the heel is-turned to bring all of its parts against the cutters; but while the cutters rotate, the disk 17, which also contacts the heel and regulates the depth of the cut, may stand still, but in fact, rolls around the periphery of the heel as the heel is turned against it and it does not go fast enough to wear a channel in the heel.
While I have described my invention with more or less minuteness as regards details of construction and arrangement and as be ing embodied in certain precise forms, I do not desire tobe limited thereto unduly or any more than is pointed out in the claims. On the contrary, I contemplate all proper changes in form, and arrangement, the omission of immaterial elements and the substitution of equivalents as circumstances may suggest or as necessity may render expedient.
I claim:
1. A rotating shaft having a reduced end and a threaded bore in said reduced end, a sleeve mounted on the shaft said sleeve having a disk extension with a depression on one side, a disk having a hub mounted in the reduced end of the shaft and in the hub of the disk, and said disk also having peripheral cutter-s, a shaft extension having a threaded end screwed into the threaded bore of the shaft, said extension having an enlargement fitting the bore of the hub and having a disk extension bearing against the cutter disk to retain the assembly of the cutter, and a bearing disk mounted on the outer end of the shaft extension.
2. A rotating shaft having a reduced end and a threaded bore in said reduced end, a sleeve mounted on the shaft said sleeve having a disk extension with a depression on one side, a disk having a hub mounted in the reduced .end of the shaft and in the hub of m-" the disk, and said disk also having peripheral a bearing disk mounted on the outer end of cutters, a shaft extension having a threaded the shaft extension, :1, ball raee mounted on end screwed into the threaded bore of the the shaft extension a nut on the extension re- 10 shaft, said extension having an enlargetaining the race and ball bearings between 5 ment fitting the bore of the hub and having the bearing disk and race.
a disk extension hearing against the cutter In testimony whereof I affix my signature. disk to retain the assembly of the cutter, and ERNEST L. KEENER.
