Letters Patent No. 104,999, (lated July 5, 1870.

\ IMPROVEMENT IN PEG-GING-JACKS.

The Schedule referred to in chose Letters'Patent and making part of the same.

To all persons to whom these presents mag/ come Be it known that I, HUBERT RICARD, of Haverhill, in the countyof Essex and State of' Massachusetts, have invented a new and useful Impi'ovement-in Pegging-.lacizs; and do hereby declare the same to be fully described in the following specication and represented in the accompanying drawing, ot wnich- Figure l denotes a side elevation, and

Figure 2 alongitudinal section of a jack constructed naccordance with my invention,and havingalast applied thereto.

Figure 3 is a top view of the eccentric or double cam-plate.

Figure 4 isa top view of the upper hinged plate or base, on which the 'cam-plate is supported and turns.

Figure 5 represents the ja'ck in a position at right angles to that shown in fig. 1. My inventionhas reference to that class of devices termed shoemakers head-blocks, in which the jacking or fastening of the last is eiected by lsimply rotating the turn-plate on which the last is supported, and consists in the'peculiar construction and arrangement of its parts, as hereinafter described. A

Also, in the peculiar construction and arrangement of devicesforjacking or fastening the last.

Also, in combined latch and coupler applied to the cam-plate, in manner and for the purpose hereinafter stated. f I

Also, in 'thefpeculiar mode ot' connecting the top and'cam-pl'ates to the upper hinge-plate, whereby the two former may be rotatedv upon the latter without a liability of becoming either .set or disconnected,y as they lwould were a simple screw cut upon the spindle, and a n ut applied thereto.

In the said drawing-` a A denotes the hase-plate of the jack, which is formed of metal, and is to be Iirmly secured to the top of a pedestal, or other proper part of a shoemakers bench.

Over-lying the said plate, and hinged thereto, is another 'flanged plate o1' disk, B, which has a series' of cylindrical holes, a, made in it, to receive a couplingpin or stud, b, to be hereinafter described.

The said -plate has a cylindrical hole, B', made through it. O n the un'der side of the said plate, and around the said hole thereof', an annular chamber, c, is formed, to receive a circular` disk' or washer, d, in

whose upper surface is made a square socket, to receive the correspondingly-shaped lower end of a spi-ndle or projection, O, extending down from the top plate D, the said disk being connected to thevsaid spindle by a screw, j'.

Bymeans of the said spindle and washer, the top plate and the cam-plate are so connected or pivoted to the hingeplate B as to be capable of being either rotated upon the latter plate, or of permitting the whole to be turned bodily up into the position shown v in fig. 5. v

E is a hollow boss or projection, which extends upward from the central part of the plate B, and has an annular shoulder, g', made thereon, the upper endV o' constituting a journal for the hub or annular projection h of the plate C, which vis arranged directly over it, and so as to be capable ot being rotated thereon, as occasion may require.

The said plate (l is formed with apeculiar eccentric or double cam-groove, S, extending around the annularfprojection lli, as seen in iig. 3. This groove is formed eccentric on each side of the axis or center of motion of thc said plate.A

The said groove receivesthc lower end f' of a curved two-armed lever, G, which is pivoted to a bifurcated heel standard, H, projecting up from the said top plate, as shown in tig. 1, the upper arm g constituting the heel-pin for supporting the heel of the las't.

The object of the said double' eccentric or cam-groove is to enable the lastto be fastened or jacked, whether the top pla-te be rotated to the rightor left.

Furthermore, there is affixed to the top of the said plate C a combined spring latch and coupler, the said coupler consisting of a piu or stud, b, which extends downward at a right angle from -the latch b', and through a slot made down through the said plate. The said latch is arranged horizontally, and projects beyond the outerface of the plate C, and works up and down wi thin a "ertical slot made through the flanged rim le of the plate. By pressing the said latch downward, the stud or coupling-pin l1 will be forced into some one of the series of holes a ot' the plate 13, and will lock the said cam-plate C rmly to the plate B, so as to pre vent any rotation thereof', whenever circumstances may require.

The said top plate has a series of notches, o2, formed on its under anged'snriace, to operate in connection with the spring latch before mentioned, the object of such spring latch being to maintain the top plate in firm connection with the cam-plate, in whatever position it may be set.

v'K is the toe-rest or supporter, which is applied to two standards L L projecting up from the upper surface of the plate D, in-'the usual manner.

M is a last, applied to the jaclr.

From the above it will be seen that the topplate D and the cam-plate' C are so connected or pivoted to the upper hinge-plate B as to be freely rotated thereon, while the hinge enables the whole to be readily turned from a horizontal into a perpendicular position, so as to enable a workman to more conveniently get at the edge of a shoe when on the last, to perform the necessary manipulations thereon.

The said hinge-plate B has a stop or projection, N,

axed to its rear side, which, whenthe said plate. is

raised from a horizontal into a vertical position, rests upon aprojection, p, extending from the hase-plate A, and, arresting its further advance, maintains it in such position. l

, v It will also be seen that the combined latch and coupler, constructed and arranged as described, perforni the double function of locking the cam-'plate to 'the hinge-plate, and allowing the top-plate to be rcvposition shown in tig. 1, and the lower end of the lever VGr to he at the point j n, or within the circular -part of the groove S, the last can be easily placed upon the heel-pin and toe-rest of the jack.' In order to secure the said last firmly to the jack, I first press down the spring latch, so as to release the top plate from the cam-plate. stud bintoone of the sockets a of the hinge-plate B, and `therehylocksthe cani-plate rigidly thcreto.- Next, I rotate the'top plate either to the right or left until thelast has .become sniiiciently tightened or secured, when the elastic action oi the latch 1r' will withdraw the coupling-pin-i'om the hinge-platc,and, at the same time, the latch willhe forcedinto one of the notches c of the said top plate, releasing the cam-plate from the hinge-plate, and thereby locking the said cam-` plate firmly to the top-plate. Under this arrange# ment, the said cam and top plates canA be readily ro. tated through an entire circle, so as to bring a shoe, when upon the last, into the most convenient position for being'fpegged, or having its ysole secured to the np- This operation forces the coupling-pin or per. After the shoe has been pegged, the jack may be turned down, so as to bring the edge of the sole into a horizontal position, in order to enable the operator or workman to trim or pare the edges thereof, which, when effected, the jack may be turned into its former position. ITo remove the last from the jack, I have simply to press-down the spring latch, so as to release thc top plate from the cam-plate, and next rotate the said top plate in a direction opposite to that in which it was moved to fasten thelast, or back'into the positon'shown in fig. 1, whenthe last can' beeasily removed.

' I do not claim theinvention described in Letters Patent No. 22,340, n or any of the devices shown there -l in lbut Y i What I claim is as follows:

1. My improved pegging-jack, consisting of `the plates A B O D, the lever G, and the toe-sifpporter K, all constructed, combined, and arranged together, in manner and so to operate as set forth.

s 2. As a means of jackingthe last, the lever G, the cam-plate O, and top plate D, all constructed, conibined, and arranged, in manner and so as to operate as set foith.

3. The' combined spring latch and coupler, in coinbination'with the top plate D, the cam-plate O, and the hinge-plate- B, when all the said parts are constrnctedand arranged in manner as described, and so Vas tol operate as andfor the purposes specified.

' 4. "lhemode of connecting or pivoting the plates Gand D to the hinge-plate B, viz., by means of the spindle p0, the washer d, and the screw f, constructed,-

combined, and arranged together in manner as described.
