The tip covering portion H is generally of convex shape, but the configuration thereof is primarily determined by the external configuration of the shoe tip [6. The upper rear edge i8 oftherportion II may extend rearwardly on the shoe any suitable distance, and the rearward extension of said edge is determined by the amount of ,the front upper portion of the shoe which his desired to protect. The inner'surface I of the'toe or tip covering portion H is provided with alining I!) which may be composed of any The lining i9 may be secured to the inner surface of the portion H in any suitable manner, as for example, by means of an adheive (not shown). ,The, lower forward and outer edge of the portion H is disposed inwar ly (rear wardly and inwardly of the shoe when placed thereon) and forms in part I the welt engaging rib l2; Fromthe'welt engagingrib l2, the material of which the protector H} is composed extends radially. outwardly in a horizontal plane to form the flange I3. 1 The'convergence or June tureformedby the lower front/part of the tip covering'portion1'landthe rear part of the sole topengagingflange i31form antacute angle with relation toeach other.

"The outer edge portion of the soleto-p eng'aging suitable cushion material, as for example, felt or flannel.

flange l3 forms a right angle with relation to the vertical rim :14 which engages theperi her or the sole? :The. rirnid is preferablycoexte'nsive with the edge? I 8, thoughwhere desired; said rim may extend rearwardly alongthe edge of the sole 23, to some point beyond the edge 8 The forward portion of the lower edge 21 has-extending rearwardly therefr-om, and preferably 'at right angles thereto; the bottom engaginglipl5.

, The rear edge 22 of the lip I5 is preferably rounded as best seen in Figure 4. The inner opposed surfaces of'thefiange'l3 and the lip i5 are preferably parallel and are spaced from each other a distance equal ,to orslightly greater The rear. portions of the rim it are provided with sole engaging prongs 23 to 26' inclusive.

These prongs have .a triangle shaped point j r- .tion,,generaliyindicated by numeral zl, andia rectangular portion, generally: indicated b'yrnumeral '28, and have the point thereof, whenfit isblanked from; the sole periphery engaging vertical rim I 4; facing r'earwardly of the, shoe l1,

and the protector In. Thes pr-ongsare, formed by making a series of incisions 29, the rear portions of which are V-shaped, while the forward 7 portionsof which have parallel sides, horizontally disposed with relation to the-protector 10. After the blanking operation, the prongs are bent as best seen-in Figures 3 and 4, so that the entire prong lies outwardlyor the rim-15 th t at least, the innermost tips of the points 21 do not extendinwardlyof the inner surface of the I rim is; cThe' rimiltis composed of relatively stifi material of a low orderoi resiliency so that the prongs may be pushed into the edge of the sole 20 by pressure upon the portion 28, and when flso driven intothe sole edge, willmaintainth'emiselves in their a1tered, inwardly"displacedfposition. [The 'prongsmay be forced iinwardly 'b'y pressure in a suitable vise or press, or they may be driven in" by hammering witha lighthammer upon the rectangular portions 28; -It--maythus be" seen that the prongs rotate substantially as,

aunit about the verticalaXes 33 and to that edge.

end, the point portions filmay, if desired, be

given a slightly curved configuration so'that the said point portions lie along an arc traced by the outer edge of the rectangular portions ZBVgWhen the same are moved in toward the sole edge.

The outer surface of the protector may be treated in such manner as to take on an appearance harmonious with the'shoe with which the protector is to be used. Examples of such finishes are bright plating; colored enamel, or certain chemical'finishesfsuchgas gun-nietalling. The s brighter finishes are more suited to childrens shoes while the more subdued finishes are more adapted for adults shoes. 7

- -The-sole top engaging flange is uniform width so that the same may properly overlay the Operation 7 Theoperation of the first embodiment device is substantially as follows:

The'protector in is held'in a position corre sponding to the one it will occupy lwhen I fully v seated upon the'shoe and'witht-he ipwersuneh of thedining J9 resting upon the-outer surface of the shoe tipji fi theentire device is moved rea'r wardly upon theshoe. ;jAs' the'de'vice is; pushed to thereal, the rim htzwill be guided inposition 7 as the flange :3 slides over the upper suriacefoi the sole edge; sinceth'e pri0ngsl23 to ifiinclusiye are p s ti n utwa d y th i rme isu a' eiof the rim I4,'they do no-tcontact tl eioutensnr fage of the edgeeof .the sole 28. until theyare;pressed inwardly as, described I above. j'lhe j, deyicej is pushed into this fully seatedfposition so that the portion 35 (see Figure 2) contactstheouter .surface of the sole 2!! atthe iront' central portion t er o After the roes flhave een pr per driven intothe soleledge, the' protector becomes;
