HEEL-SOOURING GUARD.

To all whom it may concern:

Be it known that we, SILAs W. DERBY and HAROLD L. DERBY, citizens of the United States, and residents of Kirksville, in the county of Adair and State of Missouri, have invented a certain new and useful Improve-- ment in Heel-scouring Guards, of which the following is a specification.

Our present invention relates to improve heel scouring machines which will prevent the uppers of the shoes from becoming dam aged by the abradant, and in' general faoili-j tating the manufacture of shoes.

Another object of our invention, is to provide guards of the character described.

which are movably mounted in close proximity to the abradant, each guard being capable of movement in a path transversely of the abradant and acted upon to normally, but yieldably present an element to pro ect into the rand or space between the heel and lupper of the shoe, so as to extend beyondthe periphery of the abradant, the desired distance, the operator positioning the shoe to be acted upon with said element entering the rand with the heel nearest the abradant, followed by moving the shoe bodily into engagement with the abradant, oscillating or otherwise moving the shoe to accomplish v the end in view. Since the said element must be moved from normal position in order to permit the, heel to engage the abradant, the operator is enabled to more readily control the pressure of the heel against the abradant.

Other objects of our invention will appear in the following detailed description, taken in connection with the accompanying drawing, forming a part of this specification, and

in which drawing Figure 1 is a side elevation of that portion of a heel scouring machine of the type including a revoluble drum-like member carrying the abradant, and showing a guard embodying our invention applied thereto.

Fig. 2 is a sectional View through the mandrel of the machine intermediate the revoluble abradant and the guard.

Patented Nov. 19, 1918.

Application filed September 5, 1916. Serial N 0. 118,461.

Fig. 3 is a central vertical sectional view through the guard.

Fig. 4: is a perspective view of a carrier, forming a part of the guard.

Fig. 5 is a sectional view on the line 5-5 of Fig. 2, through the guard.

Fig. 6 is a perspective view of the shoe engaging member of the guard.

Inthe drawing, where similar characters refer to similar parts throughout the views, A designates a heel scouring machine in cluding a bearing B, mandrel C carried thereby, and drum-like member D, the periphery of which carries an abradant, such as sand; and E a guard embodying our invention and comprising a support F, preferably annular inshape, G a guard plate for engagement with the shoe, H a carrier for said plate movably supporting the same from support F, J a stop limiting the amplitude of movement of carrier H in one direction, and K a device, such as a spring, yieldably retaining said carrier in operative relation to the stop J, and yieldably resisting movement of said carrier in one direction.

In the example shown, the support F is provided with a transverse opening 7 to receive the end. portion'of bearing B, and in practice is disposed between the drum-like member D and bearing B in a manner to be adjustable circumferentially of the mandrelC, set screws 8 being provided to retain the support in a rigid adjusted position with respect to the bearing B. The opening 7 is of such asize as to receive the mandrel C with considerable latitude thereabout, as is clearly shown in Fig.2 of the drawing, the face 9 of the support confronting one face of the. drum-likeImember D, and in close proximity thereto.

Referring now to the carrier H, it is preferably made of a relatively fiat arcuate piece of metal, the carrier extending about the opening 7, with one end portion pivotally connected with the support at face 9, as by screw 10, the stem of which enters a screwthreaded bore 11 open to the face 9 of support F. Thus the carrier may be swung toward or from the mandrel C, however, being arcuate in shape, it has a considerable amplitude of oscillation about the axis of screw 10 without engaging said mandrel.

As to the guard plate G for engagement with the'shoe, it is secured to carrier Has by screws 12, the shanks of which enter screw-threaded bores 13 in the carrier H, the heads of the screws being received in counter-sinks 1i in the plate G. This plate is preferably of such a width as to provide an arcuate portion 15 to enter the rand or space between the heel and upper of the shoe. When assembling the plate G into operative relation to the guard and drum-like member I), it is disposed at the outer face of carrier H and next adjacent to the confronting face of member D, so as to be in close proximity to the periphery of said member.

In order to limit the amplitude of move ment of the carrier H in one direction, the stop J is provided which may be formed integral with support F and the stop J carrying a flange 16 which engages the outer face of carrier H, preferably at its free end portion, preventing movement thereof away from the face 9 of support F. The stop J- is so positioned that, when the carrier H engages the same, the arcuate portion 15 of plate G follows, but is removed from the periphery of member D as is clearly shown in Fig. 2 of the drawin Referring now to the device K, it is preferably in the form of an expansion spring disposed in a recess 17 open to the face 9 of support F, said recess being to one side of the opening 7 The carrier H may be provided with a lug 18 extending into said recess, and provided with a centering pin 19 about which a convolution of the spring extends. A centering pin 20 may also be carried by the wall of recess 17, the spring being interposed between said wall and the lug 1S, yield-ably resisting movement of the carrier H toward the mandrel C, and yieldably retaining said carrier in engagement with stop J.

When assembling the guard into operative relation to a heel scouring machine, the support F may be first adjusted so as to present the guard plate G at a position most convenient for the operator. This may be accomplished by moving the support F circumferentially of the mandrel C until in the adjusted position, whereafter the set screws 8 may be turned tight into engagement with hearing B. The shoe is then arranged so that the portion 15 of plate G enters the rand, or space between the heel and upper of the shoe and, with motion imparted to the mandrel C, revolving the drum-like member I), the operator may move the shoe toward the abradant on member D, slightly compressing the spring or device K. It is tobe observed that the carrier H together with the plate G may be moved over the face 9 of support F, but there is no danger of any portion of the upper of the shoe engaging the abradant, since the entrance of plate G into the rand of the shoe is sufficient to prevent twisting movement of the shoe which is apt to occur if a guard is not provided and the abradant engages irregular or abnormally hard portions of the heel.

Changes in details may be made without departing from the spirit or scope of our invention; but,

Vi e claim 1. In a heel scouring machine, the combination of a bearing, a mandrel in the bearplate to limit the outward movement thereof, and means for fixing the support in circumferential adjustment.

a. In a heel scouring machine. the combination, of a bearing, a mandrel in the bearing, and an abradant on the mandrel, of a support provided with a transverse opening adapted to receive aportion of said bearing and with a recess in its face to one side of said opening, a carrier disposed at the said face of said support to one side of said opening, one end of said carrier pivotally connected to said support at one of its ends, a lug formed upon the free end of said carrier and extending into the recess of said support, a spring interposed between said lug and the wall of said recess to yieldably resist movement of said carrier in one direction, a guard plate movable With said carrier, said support being adapted for circumferential adjustment about said bearing to project the guard plate in the desired direction from the abradant, and means for holding said support in circumferential ad- 10 justment.
