ICE-Runnin.

SPECIFICATION forming part of Letters Patent No. 303,287, dated August 12, 1884.

` Appncmim inca March 4, resi. (No morini To all whom it may concern,.-

Be it known that I, EDWARD S. HUNN, n. citizen 0f the United States, residing et Kala.- nmzoo, county of Kalamazoo, State of Michigan, here invented :i new and useful Iee-Itub ber, of which the following is a specification.

My invention consists in Certain improved features of construction hereinafter described and claimed.

In the drawings forming a. part of this specification, Figure l is a. side elevation of n. rubber shoe, the soie and heel being in sections, Showing the construction; Fie. 2, it brokenv horizontnlsection of the shoe-*sole enlarged; and Fig. 3 is e perspective view of a spur.

The sole of the rubber is provided, when inzrnnfnetnrin'g it; with spur-holes imving n, countersnnk recess t the upper end adapted to receive the heeded spur A, Fig. 2. These spurs are pointed et the lower end, Where they extend through the sole. The inner lining, I3, of the sole forins a. cover to the heads of ther spurs Afnnd prevents said spurs from pushing up out of piece when `trod upon by the wearer. The lining B, in inanfneturing the rubbers, is cemented in.

In the ninnniirctnre of this class of rubber goods, especial lines nin-y be provided with the spurs with e view te the especial use set forth. The spurs :ire innde as long as th e uncontraeted sole is thick. Thus the points of the spurs do Wirren not sustain the entire weight of the wearer. The pressure ofthe foot upon the rubber tends to force the )oints of the r4spursthrough Iie eins icwsoles end`1"it` `tli"iee or frozen snow.

tliespurs are shown when not under pressure of the foot; and in Fig. the spurs nre shown forced through the sole, :is when engaging the ice.

By providing the sole With the spurs when inanufneturing the goods, 'the rubber is just :is useful for its originel purpose, and but little expense'is added, and the rubber never slips, es do the c'oinnion style7 after they are nflittlc Worn on the bottoni.

Having thus described my invention, what I claim is- A rubber foot-Weer provided in the elastic sole thereof with spurs having their pointed ends extending to the lower surface only, and

their headed ends countersunk und covered by the cemented inner sole, whereby the spurs aire adapted to be forced down into the iee by the pressure of th'e foot upfn the sole, substentinlly as set forth. 4

In testimony of the foregoing I have here unto subscribed my nume in the presence of two Witnesses.
