SHIELD-OILER FOR HEEL 0R EDGE TRIMMING MACHINES.

SPECIFICATION. forming part of Letters Patent No. 500,523, dated June 2'7, 1893.

Application filed February 9, 1893. Serial No. 461,574- (No model.)

To all whom it may concern:

Be it known that we, FLETCHER D. WORDEN and JOHN M. DIVEN, citizens of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Shield-Oilers for Heel or Edge Trimming Machines; and we do hereby declare the following to be a 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.

Our invention has for its object to produce a simple and easily applied oiling device for use in connection with the shields of what are known as heel or edge trimming machines in the manufacture of shoes, more especially patent leather shoes. In the present instance we have illustrated our invention in connection with a heel trimmer.

As the trimmer itself forms no portion of our present invention it is sufficient to say that the cutter disk and shield in practice make six thousand more or less revolutions per minute, it being of course understood by those familiar with the art that the shield is a disk of metal the edge of which lies in use between the heel and the counter or upper of the shoe to prevent the cutter marring the counter or upper. As a matter of fact however the shield itself almost invariably leaves a line or mark upon the heel seat of patent leather shoes and owing to the high rate of speed at which it rotates, frequently becomes heated to such an extent as to burn the leather thereby injuring it quite seriously. This marking or lining of the heel seat of patent leather shoes we render whollyimpossible by the use of the novel shield oiler which we will now describe referring by numbers to the accompanying drawings forming part of this specification in which Figure l is a plan view illustrating our novel shield oiler in use; Fig. 2 a side elevation; Fig. 3 a side view of the shield; Fig. 4 a side view of the cutter disk, and Fig. 5 is a section on the line a: a: in Fig. 2.

1 denotes a shoe heel that is being trimmed, 2 the cutter disk, 3 the shaft therefor, and 4 the shield which with the cutter disk and an inner plate 5 are locked to the shaft by a set screw 6. These parts have beenin common use for many years and as a matter of course any equivalent construction may be'used instead of the construction herein described so far as the operation of our novel shield oiler is concerned.

Our novel shield oiler consists essentially of a pad 7 which engages the periphery of the shield. This pad may be made of any suitable material as forinstance felt, sponge, waste, or a brush. We preferably however use a felt pad as indicated in the drawings. This pad is detachably secured in a holder 8, by means of screw pins 9 or in any suitable manner. Above the pad and secured in-the holder is an oil cup 10 having a suitable cover 11, a neck 12 extending down to the back of the pad, see Fig. 5, and a regulating screw 13 by which the quantity of oil that can pass through the neck down into the pad may be regulated. The holder is preferably pivoted in position so as to permit it to be readily swung back out of the way when not in use. In the present instance we have shown the holder as pivoted at the outer end of an arm 14, the holder being secured in place by a stud 15 which engages the outer end of the arm. The arm is shown as provided at its inner end with a slot 16 through which a set screw passes by which it is secured in position ona machine, which we have not deemed it necessary to show as it forms no portion of our invention.

Having thus described our invention, we claim In combination the cutter with its shaft 3, and shield 4, the adjustable arm 14, the arm 8 pivoted to and extending laterally from the end of said arm and over, the shield of the cutter, the end of said arm being recessed on its under side, said recess extendinglongitudinally of the arm, the pad in said recess, the oil cup having a tube projecting through the arm and the set screw extending through the arm and also through the side of the tube, substantially as described.

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