Description
Letters Patent No. 107,931, dated October 4, 1810.
flaunt '(nmm cHAnLns TRASK, or LYNN, MASSACHUSETTS.
lMPROV EME NT m MACHINES FOR LASTING shoes.
The Schedule referred to these Letters Patent and making p rt. of the same.
To all persons to whom these presents mug/ come.-
Be it known, that I, CHARLES H. TRASK, of-Lynu, of the county of Essex and State of Massachusetts, have invented a new and useful Machine for Lasting Shoes; and do hereby declare the same to be fully described in the following specification, and represented in-the accompanying drawing, of which- Figure lis a top view;
Figure 2, a front elevation Figure 3 is a vertical and longitudinal section; and
- Figure 4 is a vertical and transverse section of it.
In the drawing Adenotes a prismatic box or frame, mounted on a. stand, B, in such manner as to be capable of being turned around horizontally on a tubular pivot, a, projecting upward therefrom, a couple of nuts, I) 0, being screwed on the pivot, inorder to. keep the box in connection with it and the stand.
From the upper part of the box A two standards, C I), are projected upward, in manner as represented.
Two last-supporters, EF, are screwed upon the upper parts of the standards 0 D.
One of these supporters, viz., that marked E, is cylindrical, and provided with a shoulder, (l.
The other supporter, F, is notched in opposite directions from its middle, asshown at e f. These supporters, by being screwed on the upper ends of the standards'G D, are rendered capable of being adjusted to different altitudes, as occasion may require, to
adapt them toreceive and support'a shoe-last, the toe-part of which is to rest on the. support-er F, while a cylindrical socket in thea'nkle-part of the last receives the supporter These supporters are disposed between a pair of heel and toe-jaws or lasters, G H, which, formed as represented, are fastened to the upper arms of two levers, 1 I, by means which will adniit.of =thc adj ustmeutof eachjaw to different altitudes, and its iixation'at any one of such. v i
Tothisencheach jaw or laster G H is secured to as-mar bytwo clamp-screws gvg, going through a lung slot, 71, made in the lever, and being screwed into the tail of the jaw.
At their lower ends the two jaw-levers I l are jointed to two toggles, K K, arranged as represented, sucli t'ogglcs, at their inner ends, being jointed to the upper part, Ii, of a vertical pitmrm,L, whose other part, 71', extends down through the tubular pivot a, and is connected with a pedal, 1\I,-piv'oted to the stand B, and arranged therewith in ,manner as represented.
r The rod lrbhould be so applied to the pedal as to be capable of being revolved; horizontally, in order to effect the connection of such rod with the foot i of the pitnian, into which it is screwed, the same serv v ing to enable the pitmanto be lengthened or shortened, asoccasion may require.
The lower portion, It, of the pitinan is provided with an clevating spring, n, and slides freely 1 through a horizontal=-cross-head or bar 1, from which. four, or any other suitable number 0 pairs of springs, m m, are extended upward, and arranged. in manner as rep resented.
At their upper ends. the springs of each pair fare jointed to a pair of lateral jaw-levels m m, I
. There is to the machine .a series of pairs of such jaw-levers, each pair being arranged within one of a nuinber of movable sliders or boxes, N N N,..arranged on the top f the box 13.
The pair of jaw-leverscross one another, and rest on the upper edges of .the'ends of their box N, such jaw-levers being formed more particularly as represented in Figures 5 and '6, which are side views, and
in Figures 7: and 8, which are top views of them.
Each of the jaw-levers m an is surmounted by a lateral jaw, 0, formed as represented, and applied to the jaw-lever in manner as shown in Figure 9, which denotes a vertical section of the jaw and lover.
From the foot of the jaw a tcnon, 0, projects into a mortise, p, made in the lever.
A screw,-q, projected downward from the base of the jaw, receives a shouldered nut, 0, which rests upon the jaw-lever, and is kept in place by a cap, s, fastened to the jaw-lever by screwst t, the whole being as shown in the drawing.
By revolving the nut 'r the jaw may be elevated or depressed, so as to properly adjust its upper portion of the sole of' a last, when such last may be in position-on the last-supporters E F.
From opposite ends of the several boxes or slides N, studs 0 r are extended into oblique slots Q0113] formed through the opposite sides or bars of a yoke, P, formed as shown in top view in Figure 10, and in other respects as represented in Figures 11 and 12, which are opposite side elevations of such yoke.
The said yoke is supported by adjusting-screws x x, which screw into brackets y y, extended from opposite sides of the box A, the whole being so as to enable the yoke to be elevated or depressed by the adjusting-screws.
While theyoke is bcii g raised, its oblique slots operating on the studs of jaw-lever slides or boxes N N N N, will cause such boxes simultaneously to move apart from one another, the pairs of jaws being', attire same time, so moved.
v A downward movement of the yoke will cause reerse motion of the several pairs of lateral jaws; that. 1s, they will be moved toward each other.
