SHOE JACK DEVICE Filed July 27, 1966 F I6. I FIG. 2
' INVENTC-R.
EAWEST HARDY United States Patent 3,354,485 SHOE JACK DEWQE Ernest Hardy, 25 Knapp St, Wilton, Maine 04294 Filed July 27, 1966, Ser. No. 568,275 Claims. (Ci. 12--123) The present invention is related to shoe manufacturing devices and more specifically to shoe jack devices designed to hold shoe Vamps and tips in appropriate positions enabling hand sewing.
Prior hand sewing shoe jacks were expensive, cumbersome and complicated to manufacture, they tended to soon bind in use and catch sewing thread and were unable to provide a strong grip for a last While allowing for the easy insertion and removal of the last.
In the hand sewing of shoes it is important to have a jack which may firmly hold a last and yet be universally rotatable and adapted for use by the sewer in either a standing or seated position next to the bench.
According to the present invention, unobvious modifications of shoe jacks of the past have provided a simple, less expensive, longer lasting, more easily used shoe jack.
Although such novel feature or features believed to be characteristic of the invention are pointed out in the claims, the invention and the manner in which it may be carried out may be further understood by reference to the description following and the accompanying drawings.
FIG. 1 is a plan View of the present invention.
FIG. 2 is a side view of the present invention.
Referring now to the figures in greater detail, where like reference numbers denote like parts in the various figures.
The shoe jack 1 of the present invention comprises a right angle twisted vertical member 2 pivotally mounted at its lower end 3 to the work bench 4 by bracket means 5 comprising two angle sections 6 each of which containing mounting holes 7 and a larger hole 8 situated on the opposite leg and suitable for mounting the vertical member 2.
The mounting means 5 are mounted to the work bench 4 by ordinary fastening means such as bolts and nuts, sheet metal screws, or if the work bench is of wooden construction, by ordinary wood screws.
The vertical member 2, having a hole 9 of suitable size for pivotal mounting between the angle section 6 is mounted to the bracket means 5 by a bolt 10 and nut 11 running through holes 8 of the angle sections and through hole 9 of the vertical member 2. An additional configuration utilizing lock washer 12 may be emplaced on bolt 10 before the nut 11 is emplaced on bolt 18.
The bolt 19 and nut 11 are tightened so that the vertical member 2 may be moved to any desired angular position about bracket means 5 and remain relatively fixed in such position.
The lower end 3 of the vertical member 2 is preferably rounded to avoid protruding corners which are likely to catch sewing thread as a vamp is being sewn.
The vertical member 2 has a 90 flexural twist 14 between the upper 13 and lower 3 ends.
Upper angle bracket 15 is pivotally mounted at upper end 13 of member 2.
As shown in FIGS. 1 and 2, the face plate 23 comprises a flat member with a hole 24 at its upper end designed to align with holes 16, 17 and bushings 18, 19, the face plate 23 joining the bracket 15 to the vertical member by means of a bolt passing through the holes 16, 17. A pin 25 runs through face plate 23 and vertical member 2 holds face plate 23 in a rigid vertical position.
Additional holes 26 run through the lower end of face plate 23 and hole 27 runs through vertical member 2. Through these holes 26, 27 a rigid wire 21 is inserted which will prevent sewing thread used in sewing shoe Vamps from being caught under the face plate 23 or on "ice the pin 25 at the space between the face plate 23 and vertical member 24.
A last holding bar 28 is pivotally attached to the upper angle bracket 15. The attaching means comprising holes 30, 31 through angle bracket 15 and bar 28 respectively. A bushing 32 is further emplaced between the bar 28 and horizontal lug of angle bracket 15 and aligned with holes 38, 31, the bolt 33 running through angle bracket 15, bushing 32 and bar 28. Emplaced over bolt 33 at its head between bar 28 and tightening :bar 28 is a second brass bushing 35 covered by a steel washer 36.
The nut is tightened so as to provide adequate rigidity and rotation about bolt 33.
A toe rest 37 is fabricated of a suitable rigid material and is looped over the head of bolt 33 forming a smooth end with the bar 28.
The toe rest 37 is fastened to the bar 28 by ordinary fastening means such as bolts and nuts running from the toe rest 37 through the bar 28. The raised portion of said toe rest 37 is emplaced over the nut 34 and bolt 33. The end of the toe rest 37 touches the end of bar, 28 to avoid the catching of sewing thread under said toe rest 37. A toe pad 38 of rubber, plastic or other suitable material is mounted to the upper portion of the raised portion of toe rest 37 by ordinary mounting means such as adhesive mounting means.
The end 39 of horizontal bar 28 is angulated slightly toward the upper portion of said horizontal bar 28 and is bifurcated.
Hinging means 48 comprising two rigid blocks 41 with hinge pin 42 running between the blocks are mounted to the underside of horizontal bar 28 near bifurcated end 39 by ordinary mounting means such as bolts.
A J-shaped, shouldered cylindrical member 43 having a hole 44 at the end of its leg, is mounted to the hinging means 40, the pin 42 running through hole 44 and is so shaped as to pass between the bifurcated ends 39 of the horizontal bar 28.
The opposite leg of the J member 43, comprises a shoulder 45 at which point the diameter increases to that of the upper cylindrical portion 46 which is of larger diameter than the lower portion of the J bar.
The upper face of the upper cylindrical portion 46 contains a cylindrical hole 47, which is threaded.
A U-shaped shoe last bar 48 comprising a rigid cylindrical member shaped in the manner of a U and threaded at one end is so threaded as to mate with and be emplaced in the threaded hole 47 of the upper cylindrical portion 46.
A spring 49 is emplaced around the lower portion of the J bar 43 between the upper shoulder 45 and the bifurcated end 39 of the horizontal bar.
In operation, the unthreaded end of the U bar 48 is emplaced in the opening 50 of the shoe last 51. The last is then turned and placed over the horizontal bar 28-.
Clearance is provided for such turning by pushing the I bar 43 away from the horizontal bar 28 against the resistance of the spring 49, while obtaining leverage against the spring 49 by pushing the end of the last 51 upward. When the toe of the last 51 is over toe rest 37, the I bar 43 is released and the spring compression forces the last 51 against the toe rest 37.
The U 48 bar may be raised or lowered by rotation in the threads of the hole 47. The U 48, moveable with its threads is rotatable to swing away from its position above the bar 28 and enter the opening 50 in a shoe last 51.
The compression of the spring 49 firmly holds the last 51 with a vamp in the toe rest 37. The bushings 32, 35 respectively allow free rotation of the bar 28 at the direction of the sewer yet are adapted to hold position against free movement under the tightening of the nut 34 and bolt 33. The bolt 20 fits flushly into hole 17 which is threaded,
1:3, leaving no protuberance. Thus, there is no impediment to catch the long sewing thread used by the sewer.
It is preferable for the movements of the jack of the present invention to be freely available, yet the jack should not be loose, which would require extra handling by the sewer. The bolts 20, 34 permit theconnections whichallow universal movement to be tightened so that they are firmly held, yet easily yield to the position required by the sewer for sewing. The rigid wire 21., rounded endSand non-protrusion of bolt 20 and rounded upper end 13 provide practically no areas, for thread hitching. The bent-overfront of the toe rest 37 resting on the last holding bar also restrains the thread from tangling of the past. The bushings 18, 19, 32, 35 allow for free movement even when the bolts 20, 33 are fastened tightly.
The twist 14enables the simple mounting configuration of the vertical member 2 and enables the sewer to stand using the jack, or sit, rotating the jack to a comfortable position for work as required or desired.
The terms and expressions which are employed are used as terms of description, it is recognized, though that various modifications are possible within the scope of the invention claimed.
Having thus described certain forms of the invention in some detail, what is claimed is:
1. A shoe jack for holding a shoe last used in the hand sewing of shoes comprising bench mounting means, a first member of said shoe jack, adapted to be rotatably mounted in said bench mounting means at one end, said member including a 90 flexural twist, an angle bracket, mountingmeansadapted to rotatably mount said angle bracketto the other end of said first member, a last holding bar, means adapted to rotatably mount said lastholdingbar to afreeend of said'angle bracket, a toe rest on one endoftsaid last'holding bar, said toe rest including means forming a flush surface with the end of said bar, and last holding means, said last holding means mounted on the other end of said last holding bar, said last holding means being hinged beneath said last holding bar and including a spring biased against the upper portion of said last holding bar and a flange on said last holding means and a rotatable U shaped bar adpted to fit into the opening of a shoe last.
