MACHINE FOR DRESSING HEELS OF BOOTS AND SHOES.

Specification of Letters Patent No. 23,245, dated March 15, 1859.

T o all whom it may concern.'

Be it known that we, HoRA'rIo GUILD and LUTHER HALL, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new or Improved Machine for Dressing or Shaping Heels of Boots or Shoes; and we do hereby declare that the same is fully described and represented in the following specification and the accompanying drawings, of which- Figure 1 is a top view of the said machine; Fig. 2, a front elevation of it; Fig. 3, a rear elevation, and Fig. A, a longitudinal and vertical section of it.

The nature of our invention consists 'in the combination of adjustable heel jaws and a pattern with a curved supporting rack and a self adjusting knife or knife frame, the machine being intended for the purpose not only of holding or clamping a boot or shoe, while on a last, but for giving proper shape or form to the edge of the heel with refer ence to the contour of the heel part of the upper leather of the said boot or shoe. In this respect our machine differs very materially from that described in the United States Patent No. 18,217, and consequently we lay no claim to the said patented machine nor to the subject of the claim of the patent thereof, our invention being an improved machine and capable of trimming a heel while aro'ectino' from a boot or shoe l b 7 whereas the machine of said patent is simply for forming or cutting soles prior to their application to boots or shoes, and contains no means of clamping a boot or shoe in manner as it is held by our machine.

In the drawings A represents a bed plate or frame supporting an upright shaft B; this shaft has a handle O, on its upper end and a gear or pinion D, affixed to its lower end, the said pinion being made to engage with a curved rack E, or rack plate formed as shown in the drawings. This rack or plate is constructed with a curved slot L, eX- tending through it vertically and for the reception of one or more projections or pins p, which pass through it. The said pin or pins are carried through a supporting washer d, and from thence pass through the slot L, into the bed, the same being so as to connect the curved rack to the bed and allow the former to be put in movement under the bed while the shaft B, is being rotated. The said curved rack carries a pair of movable jaws F, G, formed as shown in the drawings, each of them being applied to the rack so as to be capable of turning on a fulcrum or pin 7, extending from it and arranged as shown in Fig. 1. Each of the said jaws rises above the upper Surface of the rack E, and has its external vertical surface H, formed parallel to its inner vertical surface and so as to compose the pattern or guide for a self adjusting knife frame I, to rest and act against. The said knife frame carries a knife or cutter K, and slides freely on the bed plate A, between parallel guides g, g, and is pressed forward against the pattern by a spring 7L', arranged as shown in the drawings. There extends upward from the curved rack plate in a position as shown in the drawings, a vertical shaft L, which, near its lower end or journal carries an eccentric or cam M, which has its edge or periphery in contact with the outer edge of one of the jaws. A crank N, projecting from the upper part of the said shaft is connected with the opposite jaw by a connection rod O. Furthermore, a lever P, projects from the upper end of the said shaft as shown in the drawings, the whole being so as to enable a person by turningthe shaft to cause both jaws to simultaneously approach one another in order that a boot or shoe when placed between them may be suitably held by them preparatory to the operation of trimming the heel, the position of the shoe or boot under such circumstances being indicated by red lines at R, in the figures. After a boot or shoe may have been fixed to the curved rack by the clamping jaws its heel may be suitably formed or trimmed by turning the crank C, so as to put the shaft B, in'revolution. This will cause the rack or rack plate to be set in motion whereby the leather composing the heel will be forced against the cutting edge of the knife, which by means of its spring will be caused to adjust itself to the pattern previously properly adjusted by the movable jaws.

Frein the above it will be perceived that whatever may be the width of the heel part of the upper -leather of a boot or shoe when on a last the clamping jaws of the machine will readily adjust themselves and the patmade to operate substantially as hereinbefore specified.

In testimony whereof We have hereunto set our signatures.

HoRATio GUILD. LUTHER HALL.
