BOOTSTRETCl-HER.
SPECIFICATION forming part of Letters Patent No. 309,154, dated December 9, 1884.
Application filed October 3, 1S83. (No model.)
To @ZZ whom, it may concern:
Be it known that I, Isaac WATSON MYERS, ofthe city of Hamilton, in the county of fentworth, in the Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Boot-Stretchers5 and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same.
The invention relates to further improvements on my boot-stretcher for which Let-ters Patent of the United States were granted to me on the 24th day of January, 1871., No. 111,137.
My first improvement relates to forming and constructing the heel and skeleton frame in one entire piece, my former one having them in two pieces, which is objectionable. My said improvement causes the stretcher to be more simple and durable.
Second. An objection was held to the old stretcher in that the heel portion sometimes slipped up in the boot when the device was in operation 5 and my second improvement consists in forming a point on the outer end of the worn1-rack, and made to project through a corresponding opening in theend of the sliding heehpiece. In the operation of stretching a boot, as soon as the turning of the heclstud commences, the said point projects outward into the heel of the boot about to be stretched and holds the heel of the stretcher firmly in place while the operation of stretching is being accomplished. As soon as the stud is reversed, the said point is withdrawn, which allows the stretcher to be easily removed from the boot.
Third. In my former device the worm-rack, operated by a worm at the heel portion, could not move as far in and out horizontally as I would wish; and my third improvement consists in cutting a recess diagonally at a proper angle in the roof of the heel portion of the instep, and placing therein at the same angle the disk provided with a worm that meshes into the worm-rack, by which one portion only of the worm is actuating the said wormrack at once. The other portion not meshing into it is above its teeth, and consequently al lows thc rack more latitude to operate the sliding heelpiece.
Fourth. A, slight improvement is made on the position of the hinges for the wings or side pieces, the old ones being hinged too far forward, which restricted their length and expansion and consequent usefulness. My fourth improvement consists in j hinging the said wings opposite the heelstud,by which the said wings or side pieces are rendered longer and more capable of their swell portions being pressed outward to better advantage.
Fifth. I construct the upper section or in step of the last and the top part of the heelpiece or roof of the worm-disk in one entire piece, with holes drilled in the same at the proper places for the screw-studs to project through. In my former stretcher these parts were separate, with slots eut in the same for the two foot-screw studs to pass through, and which required a recess in cach screw, which was objectionable. 'Insteadof the said recess in the screws, I now place a collar around each of said screws, which have a bearing on the inside of the slanting portion of the instep. This change makes the device more easy of manufacture as well as more substantial.
Sixth. In my former or first stretchcrI employed two separate studs or bearings. for the foot-screws-one on the under side of the upper section. or instep, and one on the lower or skeleton portion. I now do away with the upper stud, elongate the lower one, and drill two holes in it for bearings for both screws, which improves and strengthens the device. I also cast on the underside of the said instep or upper section two lugs or projections, be-
Eighth. In my `former boot-stretcher I se cured the toe part ot' the skeleton or lower portion of the last to the same part of the upper section or instep of the last by ascrew. I now do away with this method of securing the IOO said parts together, and in lieu thereof I cast on the toe part of the instep a projection curved toward the point, and'its lower end mad/e to pass through an opening in the skeleton frame, which holds the two parts of the device sufficiently together to answer all purposes.
By reference to the drawings forming part of this specication it will be seen vthat Figure lis a side elevation of my improved bootstretcher. Fig. 2 is a plan of the same with one of the side wings removed. Fig. 3 is a Vertical longitudinal section. Fig. 4L is aplan with instep proper removed, also the side wings or plates and the upper section of the former broken to show the interior arrangement of the various parts. Fig. 5 is a plan of the under side of the worm detached that actuates the worm-rack and sliding heel-piece. Fig. 6 is a side view of the same.
Full particulars of the working of my rst boot-stretcher may be seen by reference to my patent cited above, No. 111,137, dated J anuary 24, 1871.
A is the metallic frame or skeleton forming the lower part of the last, and in which-the heel or lower part form a solid part of it. Its central portion is provided with a stud, r, slanting upward toward the front,and having two holes drilled in it to receive the ends of the screws C and H, said screws being provided with collars s s, surrounding them and made to press against the standing portion of the instep G. The said screws also pass through the nuts I and C.
B is a sliding heel-piece having its shank or inner end moving in aslot in the heel portions of the skeleton frame, and made to operate by a worm-rack, a, set longitudinally into it, and having its outer end pointed, as at t, Fig. 3, and made to pass in and out of t-he heelpiece B through the hole a, to hold the heel of the stretcher firmly in the boot as it is being stretched. The worm-rack is actuated by means of the disk B', set on an incline in the diagonal recess c, and provided with a worm, a', as seen at Figs. 5 and 6,- one portion only f which meshes into the said worm-rack and moves it when actuated by a socket-wrench placed on its shaft, which projects up through the heel portion ofthe device.
F F are the wings or side pieces, curved to the outline of the foot, and provided at their broadest part with an internal vertical rib, F. They are hinged vat their rear ends to the center of the heel portion of the machine, by which means they are made longer and more capable of expansion at the opposite ends or swell portion. Y
By reference to my said former patent it will be seen that the instep and heel portions (marked G and A, respectively) are two separate pieces; but I now make them in one piece; and in my first patent the instep G is shown fastened to the skeleton or base piece at the toe by ascrew, c. This I do away with, and
form a projection, w, cast on the under side of the toe of the said instep portion, and allow it to pass down into and through an opening, so, made in the skeleton frame A. This device holds the parts together j ust as well as and is more convenient than fastening them by a screw, as formerly.
On my first boot-stretcher I constructed a hinged prop to the instep-plate proper, J, which prop rested on the floor of the skeleton frame. By reference to Fig. 3 it will be seen that I now construct a solid prop, z, cast to the said instep-plate proper, J, and'which passes through an opening in the plate G, and its lower end rests in a groove of the skeleton frame, which keeps it in its place.
II is the screw which passes through the nut I for moving the wedge E, which presses out the side wings, F F.
C is the lower screw, passing through a nut,
C, for pushing out the slotted toe-piece D,
which slides in the forward part of the skeleton frame.
M is a screw which passes through a nut, L, attached to the rear end of the instep-plate proper, J, and rests in the recess o of the most y elevated portion of the instep G. By turning the said screw with a socket-wrench the 1nstep-plate proper, J, may be raised to stretch that corresponding part of a boot.
I I are the arms, whose front ends interlock with the wedge E, and having the nut I between their upper ends. r.Iurning the screw H pushes the wedge forward and presses out the side wings. By turning the screw C the toepieceD is projected forward, it being connected to the nut C by arms similar to those marked I.
N are lumps or movable bosses, which may be placed at different parts of the device, as
IOO
may be found necessary to enlarge that part Vof the boot where growers of corns require it.
The screws are cut with left-hand threads, for convenience, and squared on their heads, to be easily rotated by a socket-wrench.
It will be seen that the instep G, the skeleton frame A, and the side pieces or wings, F F, are all secured together at the center of the heel by the hinge-pins m, lugs being cast on the whole of them to form the hinges, rendering the machine less complicated and easier made.
Having thus described my improvements, what I claim as my invention, and desire to sccure by Letters Patent, is-
1. In a boot-stretcher, the combination ofthe instep G and heel portion, made in one piece, with the screws C H ,worm-disk B', and pointed rack a, substantially as specified.
2. In a boot-stretcher, the combination ofthe worm-rack a, provided with a point, t, heel piece B, inclined worm-disk B', and metallic frame A, substantially as specified.
3. In aboot-stretcher, the combination of the diagonal recess o in the heel portion of the instep G, the inclined disk B', worm a', and wormrack a, to operate substantially as and for the purpose specified.
IIO
4L. In boot-stretcher, the combination of the wings or side pieces, F, and heel portions A,the
former hinged at or about the center of the latter, substantially as and for the purpose speeiiied.
5. Inuboot-st-reteher, tlleeoinbinution ofthe instep G, screws C II, und collars s s, substantially as und for the purpose specified.
6. In a boot-stretcher, the stud r, east on the skeleton frame und inude to pass up to the roof of the instep G, und steedied in place between tlie lugs y y, east on the roof of said instep, us described.
7 In u boot-stretcher, the solid prop z, oust on the toe of the instep-plate proper, J, und made to slide in a groove in the bottom of the skeleton immens und for the purpose speeied.
8. In a boot-stretcher, a projection, w, east on the instep G, and an opening, fr, in the 2o skeleton frame, by which, :is the former enters the latter, the two parts are united, substantially as and for the purpose specified.
9. In u bootstretoher, securing the instep G, the skeleton frame A, and Wings or side pieces, 25 F F,together by hinge-pins m at the center of the heel, substantially as und for the purpose specified.
