"WORK-SUPPORT.
Specification of Letters Patent.
Patented May 1s, 1920.
Application filed May 21, 1915. Serial No. 29,602.l
To @ZZ whom t may concern Be it known that I, ARTHUR BATES, a subject of the King of England, residing at Leicester, Leicestershire, England, have invented certain Improvements in 'Vorkupports, of which the following description, in connection with the accompanying drawings, is a' specification, like reference characters on the drawings indicating like parts in the several figures. i
This invention relates to the manufacture of shoes, and in particular to the manufacture of shoes made of fabric such as felt. It comprises an improved method of manufacturing such shoes, as well as novel apparatus for practicing the method.
In the manufacture of shoes of felt or other fabric it is desirable to shrink the materials of the shoe over the last in order to cause theshoe to conform more closely to the shape of the last and thus to improve the appearance and fit of the completed shoe. lt is evident that the portions of the shoe surrounding` the cone of the last will not be treated as efficiently as the forepart portions, since they are unsupported at the upper end of the cone, and the shrinking operation tends to draw them down so as to injure the shape of the rear part of the shoe.
My invention in one aspect obviates this difliculty by engaging those parts of the upper which lie on the cone of the last and iolding them against slipping or drawing down over the cone while subjecting the shoe to the action of moisture. In another aspect the invention consists in subjecting the shoe while on the last to the action of moisture and simultaneously stretching the shoe over the last. The apparatus preferred for the practice of the process which is shown in the drawings not only holds the rear portions of the upper on the last, but actually stretches this part of the shoe durino the moistening operation. A good appearance, as well as correct shape and fit of the shoe are therefore assured.
An important feature of the invention, therefore, comprises an apparatus for effecting the shrinkage -of a shoe on a last, in combination with means for holding the rear part of the upper in position on the last whereby the shape of the rear part of the shoe is not affected by the shrinkage. The apparatus shown in the drawings embodies the further advantage of positively stretching the upper over the rear part of the last.
Another feature of my invention consists in the combination of means for effecting shrinkage of a shoe upper with a support constructed and arranged to act upon the upper and the last so as to stretch the upper over the last during the shrinking operation.
Another feature of the invention comprises a compartment adapted to receive a shoe for treatment through an aperture, a work support arranged to carry the shoe into and out of the compartment, and means for closing the aperture after the insertion of the shoe.
These and other aspects and features of the invention including details of construction and combinations of parts will now be described in connection with an apparatus for shrinking the parts of shoes made of felt or other fabric. lt will be understood, however, that the invention is not limited to the particular construction described nor to its application to the type of apparatus referredl to, as it could be embodied in other constructions or applied to other types of apparatus or machines without departing from its scope. For example, a work support having the characteristics of the present invention is capable of general use in'the manufacture of boots and shoes.
Inlthe drawings "Figure l is a sectional side elevation of the apparatus, showing an open position thereof in dotted lines;
Fig. 2 is a rear view with one cover plate broken away;
Fig. 3 is a section onthe line 3-3 of Fig. 1; and v Fig. 4L is a detail.
The apparatus comprises a base 10 upon which is secured a casing 11 of sufficient size to accommodate two shoes placed side Y work supports are the same in construction and arrangement, one only will be described. Each work support comprises a main arm 19 pivoted on the rod 18 and about midway between its ends provided with ears 2O between which are pivoted a pair of workclamping levers 21. A head 22 is pivotally arranged at right angles to each workclzgnping lever and forms the work-engaging portion thereof. Each head is covered with felt 23 or other non-abrasive material. To cause the levers to be moved toward one another to grip the shoe between them a rod 24 extends through a hole formed in each lever and has pivoted upon one end of it a vcam lever 25, the cam on which is adapted to bear against one of the work-clamping levers. The other end of the rod has screwed upon it a winged mit 26 between which andthe other work-clamping lever Va coiled spring 27 is interposed. When the cam lever is turned to bring the cam into action the two levers are pressed against the shoe 28 with a force which is determined by the strength of the spring 27, the winged nut enabling the strength of the spring to be varied as required. A second spring 29 also surrounds the rod and is located between the two work-clamping levers and tends to hold them apart in readiness to receive a'shoe. To maintain the levers in an upright position when no work is in the work support, 'the main arm 19 is provided with a spring-pressed plunger' 30 which bears upon flattened portions 31 formed on cach of the work-clamping levers near1 their point of connection with the main arm.
The upper end ofthe main arm 19 is forked at 32 and between the ends of the forks is pivoted a lever 33 one end of which, 311,'constitutes a rest for engaging the heel seat of the shoe. The other end of the bent lever is forked at 35 and journaled in the forks is a stud 86 through which a screw Br'gpasses loosely and screws into another stud 38 journaled in the forks of the main arm 19 below the pivot of the bent lever.
The screw is provided with a handle 39 by which it may be turned to bring the heel seat rest 34 nearer to or farther from the work-engaging portions 22 of the workclamping levers toA accommodate shoes of different sizes or to alter the pressure the work-clamping levers exert against the sides ofthe-last a0.
The cover plates al which close the casing when the apparatus is in use are secured to the two main arms 19 by screws 42, and the arrangement is such that when the work supports are moved into position to hold the shoes within the casing. the casing is closed by means of the cover plates. In order that the casing may not be larger than is necessary for the treating of the shoes, the lower part of each of the main arms 19 and the rear end of each bent lever 33 and its adjusting screw extend through apertures 43 and lei respectively formed in the cover plates.
ln the use of the apparatus in practising my novel process the work supports are swung outwardly to remove their clamping members from the inside 'of vthe casing. .Each shoe is then placed with its heel seat agiinst the heel seat rest 3a and the cam lever is turned to cause the cam thereon to press the work-clamping levers toward one another so as to clamp the sides of the heel or counter portion of the last between them. As the sides of this portion of the last taper from the heel seat toward the top of the last, the pressure of the workclamping levers 21 against the last will cause the last to be forced upwardly in theupper so as to force the heel seat of the shoe against the heel seat rest 34, stretch the upper over the sides'of the last, and cause it to conform closely thereto. This operation is materially assisted by the friction between the felt 23 and the material of the shoe. The shoe is confined to the last only at the points where it is engaged by the members 2f), being' free to draw andshape itself to the last at other places. The action of the steam will cause some portions to shrink and others to stretch, rilepending upon the initial local discrepancies in shape between the shoe and the last. This will-continue until a condition of equilibrium is reached. The clamginY action of the members 22, in, crowding' the last up into the bottom of the shoe, will, in effect, produce a downward creeping action of the shoe upper relatively to the last. Conveniently in use the shoes are clamped in the work supports alternately, one shoe being steamed while a change is made on the other support, each work support being moved inwardly when ready to bring its shoe within the casing. Then a felt shoe provided with a leather sole is being steamed in the apparatus, the sole may be protected from the action of the steam by means of a suitable cover-which may be clipped in between the shoe sole and the, heel seat rest 34 or otherwisesecured to the rest, the lever 33 that supports the said rest or some other suitable part of the a p p ar atus l-laving described my invention, what I claim as new and desire to secure by United States Letters vPatent is 1.
