Description

certain new and useful @mman STATES PATENT @Erica IMPROVEMENT IN PEGGlNG-JACKS.

4Specification forming part of Letters Patent No. 54,369, dated May 1, 1866.

To all whom it may conce/rn:

Be it known that I, GEORGE A. KNOWL- TON, of Natick, in the county of Middlesex and State oi' Massachusetts, have invented Improvements in Pegging-Jacks, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which- Figure lis a central vertical section through my improved pegging-jack. Fig. 2 is a section on the line .t a: of Fig. l; Fig. 3, detail to be referred to.

My invention consists in making the heelstandard adjustable vertically for the purpose of accommodating the varying heights of the different styles of lasts, and bringing the heel of any boot or shoe at the same relative height with the the toe, whereby the operator can work to better advantage, and the liability oi straining or injuring the last is avoided, and my invention also consists in certain details to be referred to hereafter.

To enable others skilled in the artto understand and use my invention, I will proceed to describe the manner in which I have carried it out.

In the said drawings, A is the head-block of a pegging-jack, the center of which is bored out to receive the lower orv flanged portion, a, of a circular bed-piece, B, which is provided with grooves b, in which slide the heads o of the bolts d, which pass through the lower portions of the standards C D, upon which rests the last E with the boot or shoe to be pegged,

.the toe being supported. by the standard (l,

while the heel is supported by the standard D. The toe-standard C is made in one piece, oi' the form shown in section, Fig. l.

The heel-standard D is composed of two pieces, ef, the piece e moving horizontally to and from the center of the block A, while the piece f is provided with a triangular groove, g, and is guided vertically up and down within the piece e upon ways h. (See Fig. 31)

Near the upper end of the piece j' of the heel-standard D is pivotcd, at t', the arm or lever F, which bears the spindle j which tsinto a hole made in the heel of the last E, and by which it is supported.

G is a rod, the upper end of which is pivotw ed at 7c to the arm or lever F, while its lower end is pivotcd at l to a bifurcated rod, H, the lower end ot' which passes into a slot, m, formed in the lever I, and is pivoted thereto by means of the pin n.

At one side of the bed-piece B rises two lugs, J, to which is pivotcd the outer end of the lever I, while its inner end is bent around, as seen in Fig. 1, and moves in the circular hole formed in the bed-piece B, which is cut away at o to admit of the lever I being vibrated up and down by a rod or strap, p, for the purpose ot' bringing the toe ot' the last containing the bootor shoe snugly upon the toestaudard C during the operation ot' pegging.

Each of the rods G H is provided with 'a number of holes, q, so that the position of the pin by which they are connected together may be changed to lengthen or shorten the rods when it becomes necessary to raise or lower the slidingpiece j' in order to accommodate the heights of the diierent styles of lasts, (ordinari-ly termed boot, brogan, womans and balmoral iasts,) the piece j' being provided with a number of circular holes, r,

or bolt, s.

I make the length of the lever F, which bears the spindlej, shorter than has been the ordinary practice, in order that-it may not come in contact with the last or leg of the boot while being pegged. I am enabled, however, to compensate ior the loss of sioned by means of the lever I.

Oparation: The lasts with the boot or shoe to be pegged being fitted onto the spindle j,

the standard C is brought under the toe of the last, and both standards C and D are then adjusted horizontally on the bed-pieceB by means of the bolts d and grooves b, to a position for bringing' the work as nearly as practicable over the center of the .block A. The piece f of the heeLstanda-rd D is now raised and held by the piu s at such a height that the heel of the last is brought suiciently below the toe of the same, in order that when the lheel of the boot or shoe is secured in place the bottom oi' the sole and heel will be in the same horizontal plane. The strap p is now tightened by so` that it may be` held at the desired height by means oi' a pin leverage thus occaby means of adjustable rods G H, or their equivalents, substantially as and for the purpose specified.

5. A heel-standard made adjustable verti cally as Well as horizontally, in combination with a toe-standard made adjustable horizontally, substantially as and for the purpose described.-
