. Claims This invention relates' to heel constructions for footwear in general and has more particular reference to` a; sectionalfheel.construction for socalled highy and low shoes, and the purpose 5 of the invention is to provide a simplegeconomical and reliable construction wherein the detachable or separable lift isl susceptible of ex peditious applicationand removal.

. Although the invention is not essentially destined toA be used by any particular group or classification of people, it was conceivedY and perfectedy with the thought in mind of accommodating in particulalr personsin. isolated areas where shoe repair facilities-arenot readily avail.- able. It is a matter of common knowledge,. for example, that people in the far North or South, or incertain inland places have to do much of their own repair work and to obtainreplacement and interchangeable partsby mail order service 2'()l and otherwise. l

.Itis evident, therefore, that all sorts-of makeshift structures and' appliances are employed in attempting to satisfy personal. needs, and since Shoe lifts are subject to ready wear and distortion from rugged use I havebeen inuenced to develop. and. perfect a sectional Vheel construction which is aptly fittedl for thepurposes intended and calculated to overcome inconveniences and hardships now frequently experienced.

Although the invention; is designed for general usage, it has to do with an arrangement which is .especially feasible andpracticable for employment along the lines above intimated. Therefore, in reducing the specificv embodiment 35 to practice I have evolved andi produced anl are: rangement which. '1s' especially well:v suited for such purposes and which. is, structurally` and otherwise, distinctively different from sectional wheel and. replacement accessories withv which'.y I am now familiar; A

Briefly, the preferred embodiment ofV the4 irrvention has tol4 do with a relatively stationary or permanently attached heel section, a companion laminated lift construction and simple reliable coacting means for separably joining the two in operative relation and insuring effective jointing against accidental displacement through the instrumentality of controllable latch means. Other features and advantages will become more readily apparent from the` following description and drawings.

In the drawings:- Figure l is a perspective showing of the detachable replacement lift.

Figure 2 is a perspectiveillustration of the embedded metal jointingv plate. *Y

Figure 3 is a view looking at the bottom. of the relatively fixed section of the heel. v

FigureA 4 is a perspective drawing of the com- 5 plemental anchoring plate associated. with the xed heel section. y

Figures 5 and 6 are longitudinal sectional views taken approximately on the-planes ofthe lines 5-5 and -B., respectively, of Figure 3, showing. the lift attachedpr mounted in place.

Referring nowlto the drawings: by distinguish` ing numerals it willY be observed that the upper of the shoe is-denoted by the numeral T whereas the attached sole is indicatedvat 8". This is provided i`n. the. heel. attached'. area with a cut-out 9 which isin effect a clearance pocket or'rec'ess- Naled or otherwise secured beneath this clearance. groove 9 is the xed sectionolll of the heel structure.. Interposed between these parts is the.v anchoring or adapter plate I"I`. This'A cor-V responds-in shape with the part I0 and is provided with a series of substantially L-shaped flexible fastening, and guide prongs or fingers I2". The central portion of the plate is slit to fo'rina bend'able tang I`3'v whose free endV isV bent laterally down as at I'll' to serve as aV keeper relee ment. This depends into a keeper notch I5' cut' in the frontali ed'ge portion of thesecti'on I0;

TheA companion' lift" may" be of onel piece of material but is preferably composed' of' a' ply of leather I6 having the rubber lift I] fastened thereto. These parts` I6 and.. I'T togetherwith the'interv'ening metal jointing plate I8 form the renewable or det'achable'lift I9. Thehe'ell-sha'ped' jointingl plate I8 is. provided with a plurality'of uplbent hanger lugs' 201' apertured asY at 2 I topermit passageof theifi'ngers" I!2 therethrough. Incidentally the' xed; leather" part I0" has rectangular sockets or openings 22' formed therein to accommodate the fingers I2 as well as the lugsm2 and` to allow the parts to have therequisite relative sliding n'frotion` to' facilitate' coupling and uncoupling. The widths of the lugs 20 may correspond approximately to the widths of the socket 22 so as to guide the parts properly together. I next call attention to the numeral 23 in Figure 2 which designates an upstanding bendable or resilient latch which has its free end portion down-bent as indicated at 24 with the intervening features 25 and 26 properly shaped to provide a headed cam latch. This is cooperable with the aforementioned recess as shown in Figure 5 as well as the detent portion I4 of the liftable spring tang or keeper I3. Of course,

one might just as Well refer to the parts I3 and I4 as a spring latch and the headed shank 23 as a keeper. It is evident, however, that however the parts are described by tting the head 26 in the keeper notch I5, then matching the hanger lugs 20 with the sockets 22, the lift I9 is in readiness for proper placement in position. By lifting up the keeper I4, the part I9 can be shoved in a plane parallel to the part IU feeding the ngers I2 through the openings 2I and thus securely fastening the two parts I9 and I0 together in heel-forming relationship. The keeper I4 of its own accord drops down by spring tension to locking in position. When once it is locked as shown in Figure 5 it can be lifted up by a suitable instrument inserted into the keeper notch I5. It may thus be said that the fixed part is provided with guiding and anchoring 1ingers I2 whereas the relatively movable part I9 is provided with companion lugs. The lugs being insertable into the sockets 22 at right angles to the longitudinal dimension of the part I0 and then moved laterally in a horizontal plane to separably join the parts together. The latching means is primarily to prevent retrograde movement of the part I9 and to avoid accidental displacement irrespective of rough usage and stubborn wear.

As is evident the invention is especially adaptable for the purposes intended, for it is suciently inclusive in its features and means to provide an adequate structure to supply the needs under ordinary ranking conditions. Beyond and more than this it provides a suitable arrangement widely useful to those located in sparsely populated areas where shoe repair-work cannot be conveniently attended to by specialized persons.

While the two metal plates are associated in particular ways with the parts I0 and I9 it is obvious that they may be reversed and for this reason the plates will be referred to as the coacting jointing means between the heel sections. The parts are separately and collectively important inasmuch as the heel may be built on to a shoe at the time of manufacture, or the parts separatelyV obtained from proper sources and applied in an obvious home-made fashion. The succeeding claims should therefore be interpreted accordingly.

It is thought that the description taken in connection with the drawings will enable a clear understanding of the invention to be had. Therefore, a more lengthy description is thought unnecessary.

While the preferred embodiment of the invention has been shown and described, it is to be understood that minor changes coming within the eld of invention claimed may be resorted to if desired.
