V > , . : A still further object of the invention is to con struct the attachment with clampssuitable for engaging the skate runner and ?rmly securing the attachment thereto. ,_ ~ ' ' The novel attachment is designed with two Thus, the.‘ front 'unit is a tread M of sole.’ The rear unit1l5 is also a tread like block of'leather or suitablecomposition, but consider ably smaller, than the unit l4, conforming to the 310 size of a heel. Both .units are preferably’ oval in contour in order to‘ present asmooth. outline and afford easy progressn Also, thefront .unit I4 is convexed on the bottom between its ends ‘ to simulate the curvature of a shoe sole and 515 Another object of the invention is to build the, permit smoother progress in walking‘. 15 attachment with tread units which are both am ,ple for purposes of supportand permit smooth » The units are joined by a pair of metal plates lllaand I5a, the. plate 14a being channeled at walking movements. 7 -. ' , An important object of the invention is to de sign the same along lines of simplicity and dura bility, whereby to be inexpensive to manufacture and stand hard usage. With the above objects in view, andany others which may suggest themselves from the descrip tion which follows, a better understanding of the invention may be had by reference to the accom panying drawing, in which Figure 1 is an elevation of a conventional ice Mb to slidably receive the plate H511 and being perforated in a number of places as indicated at 20 M0 to permit a terminal hook 151) of the plate l5a to pass, whereby to adjust the spacing of the units l4 and I5 in accordance with the length of the skate. While the coupling of the plates Ma and 15a may appear somewhat depressed 25 in Fig. 1, the material in actual size is so thin as to make the coupling substantially even. The particular mode of adjustment is purely typical, and it is possible that the plates Ma and [5a could be longitudinally adjusted in other ways. 30 These plates are overlaid with leather tops l6 and I1, and the assembly of the tops with the Figure 3 is an enlarged cross section of a por-_, plates and treads secured by nails Ila, rivets tion of the attachment, showing a clamp in open or other suitable means. _ position; In order that the attachment may be readily Figure 4 is an enlarged section on the line 4—4 applicable to the skate, a special style of clamp ' of Figure 1 showing the clamp aforesaid in closed is made for the tread units, the clamps for both position; and ' ‘ units being identical. In describing one of the Figure 5 is a section .on the line 5-5 of Figure 4. I clamps it is noted that the tread plate receives When going skating, it is customary to carry a pair of standard plates I8 and I9 having out 40 the skates along to the rink or other skating turned base ?anges I 8a and 19a secured under place, ‘and then to carry the shoes around or store the tread top. The upper end of the standard them while the skates are being worn or used.‘ plate I8 is rolled with hinge ears 20 to which When the skating is over, the skates must be re is pivotally connected a hook-shaped hasp 21. moved and the shoes again put on in order that The formation of the hasp is part-circular,v and ' the wearer may walk or ride home. I have there its free end has an outward lip 22; the said outer skate of the shoe type, showing the novel attach 30 ment in place; Figure 2‘ is a plan view of the attachment; fore devised the present improvement to make end also'has a cross-slot 23. the wearing of shoes unnecessary when going to or returning from the ‘skating place, so that the bother of taking off and putting on the shoes and The standard plate I!) is formed at the top with an outward and deflected flange 24 which is perforated‘ at 24a to receive a pin 25 from under neath, the pin having a head 2541 which is re? tained by an inturned bead 24b of the flange 24. their handling or storage are eliminated. In accordance with the foregoing, speci?c ref erence to the drawing indicates a conventional ice skate at [0, the more popular type thereof in cluding a shoe l I. The skate runner is indicated The portion of the pin 25 which is immediately above the ?ange 24 is eccentrically thickened as indicated at 25b; and beyond this portion the 2 2,102,916 pin is made with a flat ?nger knob 25c. The eccentric formation 25b is laterally of the ?nger knob; and the latter is somewhat curved in a vertical direction. When the hasp 2| is open as indicated in Fig ure 3, the tread unit may be applied to the skate runner in a manner to receive the same between the standard plates I8 and I9. The to one of the divisions and looped over the run ner, and cam means operative to draw upon the hasp during the clamping action with the effect of tightening the hasp about the runner. spring metal, may be drawn over by applying a ?nger to the lip 22 to close on the crown as ground tread unit below the skate runner, a knob 250 of the pin 25 receives and projects from the slot 23 of the hasp. Now, a quarter~turn of the knob to the position shown in Figure 4 will crowd the eccentric portion 25b of the pin outwardly, to draw on the hasp and tightly ‘se cure the same to the crown l3 so that the clamp so formed securely engages the runner and ?rm ly attaches the tread unit thereto. The above operation is simple ‘and may be quickly attended to after one has put on the skates and is ready to leave for the skating place. 25 When the latter has been reached, the two at tachments, one for each shoe, are removed and preferably put into a light bag or sack, which may be tied over the skater’s shoulder or strapped to the belt. When so carried, the pair of attachments is not a hindrance, since they are light and occupy a small space. Yet, when skating is over, the attachments are readily ap plicable to enable the wearer to proceed home without delay. 35 I claim: 1. An attachment for ice skates including a ground tread unit below the skate runner, a divided receptacle for the latter, a hasp pivoted crown 13 of the runner is now opposite the open ing in the hasp, and the latter, being made of indicated in Figure 4. During this action, the 30 ufactured cheaply and be capable of hard usage. It will be evident that the novel attachment is both an article of utility v‘and convenience, sav ing time and effort. Also, it is of a nature to be simply and sturdily designed, so as to be man 2. An attachment for ice skates including a divided receptacle for the latter, a hasp pivoted ‘to one of the divisions and looped over the run ner, the free end of the hasp having a transverse opening, said clamping means comp-rising a key carried by said other division and passing through the opening, and a flat head for the key and ~rotatable to extend crosswise of the slot and lock the hasp from departure. 3. The structure of claim 2, and an eccentric ’ enlargement of the key in the zone of its pas~ sage through the slot, such enlargement crowd ing the free end of the hasp outward when the key ‘head is turned to said crosswise position. 4. An attachment for ice skates comprising longitudinally-spaced ground tread units under the skate runner embodying top and bottom non metallic sections‘ grouped with metallic inter mediate sections, co-operative extensions of the latter adjustable to vary the longitudinal spacing of said ‘units, standard plates receiving the skate runner between them and with outward bases resting on said intermediate sections, said top sections being perforated for the passage of the standard plates, means to fasten the latter to the skate runner, and means to secure said group of sections together.
