JERSEY HEEL oov'anme "MACHINQBV Application fi led November 2], 1927,. se ia1j1vof2sa5se,,1 i l This invention relates to machines for operating upon shoe heels, particularly grooved'heels, andis herein illustrated as embodied in a machine for facilitating the covering of heels with sheet material.

0 material, an operation Whichhas heretofore- One important ob ect of he invention'is to provide an efficient machine for accurately" and rapidly securing to a heel block the meeting edge portions of a piece of heel covering been performed by hand. A more specific object is to'provide a machine for tucking into the groove of a grooved 'heelblock the meeting edge portions of the covering mater al. V I V y Withthese objectsin View, the invention comprises a machine in which are combined meansfor positioning-a heel-blockand means for securing in succession to the block the meeting edge portions of thegheel cover.

In theillustrated embodiment of the inven tion, the'machine is providedwith a single means arranged to secure the cover to a heel block, as by tucking the covering magroove in the block, and is operative upon the two meeting 1I 1'Sl1CCSS1OIl.

a In this connection, invention is also to be recognized in the combinat on with a tucking blade Which is 'verythin, and, therefore, liable tolbe'deformed -if subjected to much bending force, of meansfor positioning a grooved v heel block 'withits groove in the plane of said blade, and means for effecting relative movement of the block and theblade thinner than would otherwise be practicable:

' a This is very advantageous with some kinds of 7 heel covering material, inasmuch as, it pery mits tucking the' material into the groove "without compressing the material beyon'd'the terial into a groove inthe block, the preferred form of means for accomplishing this func-- tion consisting of a' reciprocabletucking blade which is movable into and out'of the edge portions of the heel cover in the plane of the blade, to tuck heel cover ing material into the'groove. By mechanitucking blade is withdrawn the said' material can expand to fill thegro'ove, so that a very 'secure and neat attachment is obtained;

Afurther feature of the inventionconsistsin the provisionninamachine for operating upon a grooved heel block, of means co-foper-; ating with a narrow, approximately parallel walled groove in the block forpositioning' 7 theblock for an operat-i on thereon, said means of its elastic recovery l and when the a comprising a blade whichfope'rates to'tuck heel covering material into the groove- Other featuresand advantages ofthe in I tion i Fig. 2 is aviewof-the'headof themae'hine in front elevation; I v i Fig. 8 is perspective'yiew showing de-' tails of mechanism for effecting angular; ads justme'nt of the tuckingblade; I

Figs. 4, 5, 6 and'7- illustrate the successive v steps in the operation of tucking the edges o theigroove'in of the covering material in a-heel block; and j' m Fig. 8 is a perspective v-iwof the'covered. e y i In the drawings 1OJindicates abase which is designed to be supported upon a bench and upon which is-mounted a fixed heel block 190- Jaw-12' adapted to engage the attaching face sitioning memberin the form of a clamping of a heel 14 to beop'erated upon; Y A
