l Claim. 38-36) 'l'heinventionrelatestoheelsforbootsorshoes, andmore particularly toaheelofthistypein which the lower or wear lift maybe readily re-' moved and replaced.

Detachable heels known prior to my invention have not proven to be satisfactory because of the employment therein of mechanical devices for attaching the lower lift to the main .heel

Such mechanical devices not only make the pro- 10 duction of the heel expen ve, but require a nicety in the adjustment of parts which makes the production of the lower or wear lift for re, placement purposes diiiicult.-

With the above conditions in mind, I have provided a heel of the type to which the invention relates wherein the lower or wear lift of the heel is provided with studs that will frictionally engage sockets formed in the main body of the heel, said studs being of a length-not only to afford the desired'area of frictional contactbetween them and the heel sockets, but to likelihood of the accidental displacement of the wear lift from lateral stresses thereon while a shoe is being worn. A

The friction studs arepermanently connected with the wear lift and extend at substantially right angles to the plane of its wear surface, and these studs have afrietion flt with the wallsof the co-operating sockets s'ufiiciently tight to require the provision of means carried by the heel m proper for eflecting aremoval of the lift when it becomes necessary to replace same.

The invention consists primarily in-a heel for a boots'or shoasembodying therei'nja heel block aplurality of sockets therein, an ejector member carried by said heel block having a screw 1 threaded connection therewith, said sockets being symmetrically grouped in relation to said ejector, a wear lift engageable by said ejector member, and a plurality of studs permanentlysecured thereto and adapted to enter and frictionally view of a modified form of wear lift especially adapted for use with leather lifts, Fig 4 being asectiononthelineEEofFlg.5;

Like numerals refer to like parts throughout the several views. I

Referring to the drawing, the heel block is shown at 1.

it is made of leather. A- wood block is shown in Figs. 1 and 2 of the drawing. The lower or tread lift is shown at 2 and may be made of either.- leather. or soft vulcanized rubber. In a heel embodying the invention, blockl and the lift 2 are provided with co-operating means facilitating the attachmentof the .lift to the heel block and its separation therefron This; attachment means comprises a plu -rality of studs permanently secured to the heelilft, and a plurality of sockets with which the heel block is provided within which sockets the studs have a close drivingflt so that by frictional engagement of the studs with the walls of the sockets, the lift is nrmly secured in relationtothe heel block.

By the foregoing construction, the use of interlocking mechanisms, springs and other devices for securing the lift upon the heel block is unnecessary, and convenient.interchangeability of lifts and heel blocks is made possible merely by accuracy in the location of the co-operating studs and sockets when producing the parts of the heel in the factory.

It is not my intention to limit the invention to the precise details of construction shown in the accompanying drawing, it being apparent that such may be varied without departing from the spirit and scope of the invention.

Having described the invention, what I claim as new and desire to have protected by Letters Patent, is:--

1. A heel for boots or shoes embodying therein a heel block having a plurality of sockets therein,

an ejector member carried by said heel block having a screw threaded connection therewith, said sockets being symmetrically grouped in relation to said ejector, a wear lift engageable by said ejector member, and a plurality of studs per-I- block and the studs from thesockets with which they co-operate, said lift having an opening therethrough permitting the passage of an implement through the lift for actuating said screw.

A heel for boots or shoes embodying therein a heel block having a plurality of sockets therein. an ejector member carried by said heel block having a screw threaded connection therewith, said sockets being symmetrically grouped in relation to said ejector, a wear lift. engageable by said ejector member, a plurality of studs permanently secured thereto and adapted to enter and frictionallyengage said sockets'respectively, and a disk interposed between said lift and said heel block, said' disk having openings therethrough for the passage of said studs.

4. A heel for boots or shoes embodying therein a heel block having a plurality of sockets therein, a wear lift, a plurality of studs firmly secured thereto adapted to enter and frictionally engage said sockets respectively, said heel block having.a screw threaded socket intermediate said other sockets, an ejector screw co-operating with said screw threaded socket and engaging said lift, whereby the withdrawal of said screw from its socket will forcesaid lift away from the heel block and the studs from the socketswith which they co-operate, said lift having an opening therethrough permitting the passage of an implement through the lift for actuating said screw, and a disk interposed between said lift and said heel block, said disk having openings therethrough for the passage of said studs.

5. A heel for boots or shoes embodying therein a heel block having a plurality of sockets therein, a wear lift, a plurality of studs firmly secured thereto adapted to enter and frictionally engage said sockets respectively, said heel block having a screw threaded socket intermediate said other sockets, an ejector screw co-operating with said screw threaded socket and engaging said lift,

whereby the withdrawal of said screw from its socket will force said lift away from the heel block and the studs from the sockets with which they co-operate, said lift having an opening therethrough permitting the passage of an implement through the lift for actuating said screw, and a removable plug closing the opening through said lift.

6. A heel for boots or shoes embodying therein a rigid heel block having a plurality of sockets therein, smooth metal bushings lining said sockets, a wear lift, a plurality of projecting studs secured thereto, said heel block having a centrally located socket therein, an interiorly screw threaded bushing lining said socket, and a screw co-operating with said screw threaded bushing and adapted to be actuated from the outer side of said lift, said screw being adapted to engage said lift, whereby when it is unscrewed,

' it will force said lift away from said heel block.

7. A heel for boots or shoes embodying therein a rigid heel block having a plurality of sockets therein, smooth metal bushings lining said sockets,- expanding wedges seated within said sockets and operative to spread said bushingsjto secure them to said heel block, a wear lift, a

.plurality of projecting studs secured thereto, said MARTIN JOHANNES JfiRGENSEN.
