  NlTED STA E PATENTS U T S 1 Claim, 4 Drawing Figures 1,023,603 4/1912 Eggmann 36/61 ANTI-SLIP ATTACHMENT FOR OVERSI-IOES SUMMARY OF THE INVENTION My invention relates to an anti-slip attachment for shoes or overshoes, and particularly to a toothed bar which may be pivotably fastened to the sides of the heel of a shoe.  
  In use, the toothed bar is rotated to lie on the external surface of the attached heel with the teeth furnishing an anti-skid gripping surface on ice or snow. When not in use, the bar may be rotated to lie parallel to the front side of the attached heel above the plane of the sole and heel surfaces of the attached shoe.  
 BRIEF DESCRIPTION OF THE DRAWING:  
  The objects and features of the invention may be understood with reference to the following detailed description of an illustrative embodiment of the invention, taken together with the accompanying drawings in which:  
  FIG. 1 is a perspective view of the invention in use in the extended position;  
  FIG. 2 is a plan view of the invention installed in the retracted position;  
  FIG. 3 is a side view of the invention installed on a shoe; and  
 FIG. 4 is an elevation view of the invention.  
 DESCRIPTION OF THE PREFERRED EMBODIMENT:  
  Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, FIGS. l-3 show the antiskid bar installed on the heel 11 of an overshoe 12.  
  The bar 10 is formed of a rectangular strip of metal with an ear flange 16 at each end bent perpendicular to the plane of the mid-section 15 of the bar, with both ear flanges 16 lying in parallel planes. A hole in each ear flange 16 permits rotatable fastening of the bar 10 to opposing sides of the heel 11 by means of rivets 17.  
  An edge 19 of the mid-section 15 of the bar 10 is formed in the shape of pointed teeth 18, with the toothed edge 19 projecting away from the attached heel 11 in the extended position of the bar as shown in FIG. 1, and said toothed edge 19 and teeth 18 projecting towards the sole of the shoe 12 in the retracted position as shown in FIG. 2.  
  In the retracted position shown in solid lines in FIG. 3, the bar 10 lies within the plane of the exterior surface of the heel 11 and the plane of the sole of the shoe so that the-attached shoe may be employed in customary manner.  
  Ear flanges 16 are bent so as to lie snugly against the sides of the attached heel in either the extended position shown in dashlines in FIG. 3 or the retracted posi tion shown in solid lines in FIG. 3.  
  Since obvious changes may be made in.the specific embodiment of the inventionfdescribed herein, such modifications being within the spirit and scope of the invention claimed, it is indicated that all matter contained herein is intended as illustrative and not as limit- United States is:  
 1. An anti-skid bar rotatably attached to the sides of,  
 a heel of a shoe,.comprising a metal bar formed with two end flanges bent perpendicularly to the axis of the bar and {parallel to each other, said bar fitted on one edge with projectingteeth, said bar and flanges of a size to fit about the sides of theshoe heel, with the flanges of the bar rotatably attached to the opposed sides-of the shoe heel so that in a first position, the bar may be rotated to rest against the exterior surface of the heel, and in a second position, the bar may be rotated to rest parallel to the front side of the heel, with the toothed edge of the bar located on the edge of the bar opposite the edge of the bar which rests against the heel exterior sur-&#39;
