ing plate may be removed and new'studs substitiited, the plate again clamping the studs tothe sole an the heel. I I
A furthe feature of' my invention in rela: tion to the heel is forming this with a plurality of sockets or recesses. in which are located the studs. The studs each have a-shoulder which is engaged by the clamping or locking plate, the latter being attached to the heel by a screw bolt, the plate having a perforation for each stud.
The wearing studs forthe main portion of the sole are preferably attached to strips of rubber, the strips being of sufllcient length to reach from si e to side of the shoe, and they may be trimme to the shape of the sole. This rubber strip is engaged by a perforated plate,, a stud extending through each perforation, whereby such flexible plate with the studs may be attached to the sole. no My invention is illustrated in connection with the accompanying drawing in which:' Fig. 1 is the under-side view of a shoe show-- ing the sole and heel construction. L
Fig. 2 is a transverse section on line 2 -2 of 35 Fig. 1 through the sole construction.
Fig. 3 is a transverse section on the line..8:-3 of Fig. 1 in the direction of the arrows through the heel construction. 1
:Fig. 4 is a perspective view of one of the trips sertable studs used for the heel.
45 are a series of sockets or recesses l2 preferably around the edge-of the heel,- and in each of these sockets, there is a stud l3. These studs are preferably formedwith a large cylindrical section M, an annular shoulder l5, and a. re- 50 duced cylindrical section It. They are preferably formed with a hollow chamber or space H to form a better cushion. The end l8 of each stud is preferably flat. The. studs are inserted in the sockets so that the shoulders aresubstan- 55 tially flush with the lower surface is of the heel.
holding 'and clamping plate' 20 of strong fl ble material and which has perforations for the studs is then fitted over the studs engaging the shoulders IS. The plate with the studs is .then clamped in place by means of a screw 2| extending through the plate and having ahead with a kerf 22 for-engaging bya screwdriver. The screw preferably threads into a. nut 23 embedded in 'the heel, and thus firmly attaches the clampingplate and the studs to the heel. 10
In the construction of Figs. 1 and 2, a shoe sole is indicated bythe numeral 24, and against the-lower face of this, there is fitted resilient strips 25 each having a plurality of studs 26. The studs are indicated as cylindricaland each has a hollow chamber 21 forming a cushion, if desired. The strips are generally formed rectangular and are fitted close together with their adjacent edges adjoining as indicated at 28. A flexible tough clamping plate 29 has a series of 20 perforations 30 to eng e each stud or knob. The plate is then secured to the sole by means of a series of screws 3|, these screws each having a head 32. with a screw driver kerf 83. The
strips may be assembledon the sole by means of 25 the clamping plate and'then trimmed the shape of the sole or they may be 'cut to shape'before being clamped to the sole. It is desirable to have a toe strip indicated at 34 with a few-larger studs 35 to take the increased wear at the toe \30 portion of the sole.
When it is desired to remove the studs from the heel, the clamping plate for the heel is re-- moved and the worn studs are also removed from their recesses, and new studs used to replace 35 them. The clamping plate is then secured in position. In the construction of the sole, if the studs become .worn, the clamping plate maybe removed and one or'more strips 25 with studs may be used for replacement.
r 40 Various changes may be made in the details 'of construction without departing from the Referring to the drawing, a heel construction 'is indicated by the numeral l I, in which therespirit ,or scope of the. invention as defined by the appended claims.
1. In a shoe having a bottom wearing portion provided with a cylindrically shaped socket, a stud having a' cylindrical portion fitting in the socket andhaving an annular shoulder in alignment with the lower surface of the bottom wear- V ing portion with a projection portion above the shoulder, a plate "having aperforation for the projecting portion of the stud, the plate engaging the shoulder, and screws attaching the plate to the bottom wearing portion, the stud having cated substantially in alignment with the plate.
2. In a shoe a heel construction having peripheral side walls and a plane bottom surface,
the heel having a series of cylindrical socketsi extending upwardly from the bottom surface and posltioned'sliahtly spaced from the periphery of the heel, each of the sockets having a flat base forming the upper end of the socket, each 10 base being parallel to the bottom surface, a
resilient stud fitted in each socket; each stud having a cylindrical upper part of relatively large diameter fitting in the cylindrlcal'socket and having an upper end cousins the base of ll the socket, each stud having a lower cylindrical 2,074,831 a cavity completely enclosed in the stud and 10-.
portion of reduced diameter and an annular shoulder at the connection between the upper and lower portions of the stud, each shoulder being substantially in alignment with the plane of the said bottom surface, a metal plate having a series of perforations, one for each stud, the lower portion of each stud extending through a perforation, and said plate being 'in contact with the' said bottom surface and the shoulder of each stud. and means to secure the plate to the heel construction, each stud havin a completely enclosed hollow space located at substantially the line of the shoulder of the stud.
