Specification of Letters Patent.
Patented June 5, 1906.
Application filed September 28', 1905. Serial No, 279,788.
To all whom it may concern:
l 3e it known that I, JOHN O. STIvnRs, a citizen of the United States of America, re-
- siding in the city and county of Denver and State of Colorado, have invented a new and useful Nail-Olenching Device for the Heels of lVooden Lasts, of which the following is a specification.
My invention relates to improvements in nail-clenching devices for the heels of boot shoe lasts forclenching the nails of the heels of boots .andshoes to the soles when they'are nailed thereto by any machine in use for this purpose; and the objects of my invention are, first, to provide a' metal nailclenching device for .Woodenlasts that will revent the crushing and breaking of the asts when the heels of boots, shoesfand slippers are nailed tot-hem in a heel-nailing machine; second,,to provide a rigidnail-clench- 1n metal plateand thimble-oolumn, which co umn extends through the heel of the last and is ri 'dly secured to a su porting plate that is aced over the opposlte side'of the heel of t e last; third, to provide'a reinforced nail-clenching. metal heel-plate for wooden lasts that will revent the bendin of the supporting thimb e or column and t us prevent the breaking'of the heelsofthelasts fourth, to provide a metal face' late or cap attached to a metal thimble whic will protect the top of a shoe-last from being broken down; fifth,
to provide a metal thimble with a met'altop or cap to which is rigidly secured a metal these objects by the mechanism illustrated in I the accompanying drawings, in which plate that provides for the rivetin or clenchmg of the nails that hold the leat er heel to the sole of a boot, shoe, or slipper. I attain Figure 1 is a longitudinal sectional view through a last, showing in invention apiplied to the heel portion thereo Fig. 2 is a perspective view of the parts constituting my etail invention separated from each otherl Fig. 3 is a plan view of the heel. portion ofthe last with my invention removed; and Fig. eisra detail plan view of the invention, the parts being secured one to the other.
Similar numerals of reference refer to simi-.
lar parts throughout the several views.
Referring to the drawings, the numeral 1 desi ates a wooden boot or shoe last. Ver
. tical y throu h the center of the heel of the Wooden last form a hole 2, preferably an oblong-shaped-hole, the longest diameter of which ispositioned lengthwise of theheel por;
tion of the last. The heel-surface of this wooden last is provided with a rabbeted step portion, which is cut out of it to forIILa fiat bearing-surface for a nail-clenchinglplate The depth ofthe rabbeted step in t e heel is made the thickness of the'plate, so that the heel with the nail-clenching plate will still be of only its normal thickness and form. Th s nail-clenching plate is preferably made to extend entirely over the tread of the heel, and l its outer surface is curved or shaped to receive the heel-bearing surface of the inside of a boot or shoe. Upon the o posite side of the heel of the wooden last I a so fit a plate 4,
which I term a centering base-plate. This centering base-plate preferably extends oven;
the opposite surface of the heel of the last, a
flat place being formed on the top or ankle integrally with the plate to stand at right an gles'to it and which isadapted to extend into and through and fit snugly in the aperture 2 in the wooden heel. I preferably make this metal column of oblong shape to fit the oblongshaped aperture in the heel, as this form of column is a very strong form of column that does not require a very Wide aperture transversely in the heel, as a wide aperture would tend to weaken the wood of the heel. This metal column extends through the aperture even with the flat rabbeted stepped surface in the heel of the last, and its topsurface is.
level with it, and. upon it the, metal nailclenching heel-plate rests, as well as on the wood of the heel of the last,'and from theopposite sides of the 1011 est diameterflof-thisv "metal column or from t e center of the thim ble'post or column one or more integral pinsha ed portions 6 and 7 project above its top su ace and extend through two apertures 8 and 9, which are formed-in'the nail-clenching platetq receive them, two being shown in the drawings; These apertures are countersunk on the outside of the plate, and after the two ,plates and thimble-column have been. roperly .fitted and'firmly seated'in and to 'te opposite sides of the heel the-pins are riveted to rigidly clamp the two plates and columns to' the heel of. the'last' This centering base:
plate is provided with an aperture 10, whichextends intofit and also-into its ooluinn at the center ofthe heel and is adapted toe-center or centering gage and fits over a oenteringpin in the surface-plate of heel-nailing m'achines. I do iiot illustrate this heel-nailing machine, as it does not form any part of my invention.
In the place of casting the metal column 'integrally with the centering base-plate it lasts and the securing of these plates to an unyieldin metal supportingcolumn extending t ough the heels of wooden lasts, one of which plates is adapted for a nailclenching plate and the other as a centering base or foundation plate for the last, and the plates and column adapted to be inserted in a hydraulic or other power-operating ma chine expressly designed to securely nail at one stro e of its operative movement the heels of boots and shoes to their soles in a Well-known manner.
My invention is simple, strong, and durable and will prevent the heels of wooden lasts from crushing or breaking.
What I claim as new, and desire to secure by Letters Patent, is
1. Ina nail-clenching device for the heels of wooden lasts, the combination of a last having-fa heel provided with a vertical aperture t ough it, with a baseplate fitting the ankle end of said heel and containing a cen tering-aperture, adapted to center the heel in a heel-nailing machine, a metal column cast integrally with said base-plate and arranged to fit snugly in and to extend through the aperture in said heel, projectin pins on the opposite sides of said metal column arranged to project above the sur-i face of said-heel, a stepped rabbeted surface in the heel of said last, a nail-clenching plate fitted to said stepped rabbeted surface, and to rest on said plate and containing apertures through which said pins project, and arranged and adapted and rigidly riveted to the top of said metal column by said pins,.
and'toclamp said wooden heel between it and said base-plate, as set forth.
In a nail-clenching device for the heels of wooden lasts, the combination of last having a heel provided with-a central aperture extending through it, the metal centerin base-plate fitted to the top of the heel of said last, provided with a central column of metal projecting from the inside of said base-plate into and through said aperture in the heel of said last, and a centering .or gagin aperture extending into the plate and its co umn, and
adapted to gage the position of said heel in a heel-nailing machine, and having tions projecting above the to of sai column and the nail-clenchin heel-p ate fitted to the heel portion of said ast and riveted to the 7 top of said column by the rojecting pin portions of said column, w ereby said nailclenching heel-plate is rigidly su ported by said column and base-plate, an saidheel and base plates are clamped to said wooden heel, as set forth.
