An important object of the invention is to de

and stand hard usage.
With the above objects in view, andany others

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

The portion of the pin 25 which is immediately

knob 250 of the pin 25 receives and projects from

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.

tachments, one for each shoe, are removed and
preferably put into a light bag or sack, which
may be tied

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.
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

It will be evident that the novel attachment is
both an article of utility v‘and convenience, sav

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.
