8 Claims.
This invention relates to-presses for use in the manufacture of shoes and more particularly to presses which are utilized in aiilxing outer soles to lasted uppers by means of an adhesive cement.
A general object of the invention is to. provide an improved form of press in which the shoe may be clamped with a minimum expenditure of time and effort on the part of the operator and which is adapted securely to hold in position and apply pressure to lasted shoes of Avaried sizes.
More particularly, objects of the invention are to provide a shoe press having an inflatable pressure applying pad and supporting means located thereover for holding a shoe in clamped position against the pad, wherein the supporting means is adapted to be kept in a xed position during the loading and pressing operations so that pressure is applied to the shoe sole by ination alone, and wherein the shoe supporting meansv is capable of having its position varied with. respect to that of the inatable pad to compensate for extreme variations in the last dimensions employed, even, for example, such as those encountered when handling adults', chldrens and babies shoes on the same press.
Further objects of the invention are to provide a press possessing the above and other advantageous features which is simple and sturdy in construction and efficient in operation.
Other objects of the invention will in part be obvious and will in part appear hereinafter.
The invention accordingly comprises the features of construction, combination of elements, and arrangement of parts, which will be exemplified in the construction hereinafter set forth and the scope of the application of which will be indicated in the claims.
For a fuller understanding of the nature and objects of the invention, reference should be had to the following detailed description taken in connection with the accompanying drawings, in which:
Fig. l is a side elevation of a shoe press embodying features of the present invention;
Fig. 2 is a vertical longitudinal sectional view taken substantially medially through the heel post portion of the press and substantially along line 2-2 of Fig.3;
Fig. 3 is anvertical transverse sectional view taken along line 3-3 of Fig. l;
Fig. 4 is a side elevation of another form of shoe press embodying features of the present invention;
Fig. 5 is a vertical transverse sectional view taken substantially along line 5-5 of Fig. 4;
Fig. 6 is a perspective view of a housing member used in the modification shown in Fig. 4; and
Fig. 7 is a vertical transverse sectional view taken substantially along the line l--l of Fig. 4. In my copending application Serial No. 522,738, there is described and claimed an improved form of press adapted to be used for cement-affixing outer soles to uppers. press there shown comprises a base member containing an inflatable pad and having a rigid bow member extending thereover and preferably cast integrally therewith. This bow member iixedly carries toe and heel posts which are adapted `to bear on the upper part of a lasted shoe. The inatable pad there used is of special design and is capable of unusual vertical displacement. When operating such a press, variations in employed last sizes are compensated for by inflation alone, there being no opening and closing or other positional adjustment ofthe toe and heel post, such as was characteristic of the presses theretofore used.
The presently described press preserves these advantageous characterstics as to quick and easy loading and operating, but insteadrof having the toe and heel posts located in permanently fixed vertical positions, has one or both thereof located in what may be termed a semi-permanent position, with provision being made for altering this position when desired. Provision oi this last feature is especially desirable fri factory installations wherein the same press ls used in handling shoes having extremely varied dimensional ranges, as when both babies7 and adults shoes are manufactured. With the present form of press, ordinary dimensional variations encounteredl with a given type of shoemay be compensated for by inflation of the pad alone, without adjustment of the supporting means located above the pad, but when a series of shoes of an entirely different type and dimension are to be subjected to sole afiixing operations, the shoe supporting means is given a new vertical location with respect to the pad.
Referring more particularly to the drawings, there is shown in Fig. l a press comprising a base I0, provided with a pad accommodating cavity I l and with a rigid bow member I2 which preferably, though not necessarily, is cast integrally therewith. This bow member extends longitudinally over the base and carries a suitably located toe post i3 which, in the embodiment here shown, is preferably cast integrally Vwith bow member l2. Toe post i3 carries at its lower end an instep pad lll which may be formed of yield-v able rubber or the like. Also mounted on bow The preferred form of member I2 is a heel post |i5l terminating at its lower end in an elongate last engaging se'at IG which is adapted to bear upon the top heel portion of any one of a number of interchangeable lasts. During a given loading and pressing operation the toe and heel posts are adapted to be kept xed above the base Ill, and pressure is applied to the shoe sole through inflation alone. To this end, there is 'preferably located in pad cavity an inflatable pad I1 which preferably possesses the characteristic features of the vertically expansible inflatable pad described in the above mentioned copending application Serial No. 522,738.
Such a pad comprises an inflatable rubber bladder (not shown) having its interior in communication with a. lcombined air inlet and outlet passage I8 equipped at its outer end with a valve I9 which is adapted to be used for both inflating and deiiating purposes. The inflatable bladder is confined in a suitable casing, such as leather, and this casing preferably has a pronouncedly full or baggy upper diaphragm. This fullness is accentuated at the middle portion of the pad opposite the shank portion of the shoe, and the casing also preferably has side walls or gussets having an increased height at this middle portion, all as more particularly described and claimed in application Serial No. 522,738. For the purposes of the present invention, it will be understood that there is provided a. pad which is capable of sufficient vertical displacement properly to care for variations in employed last sizes so long as this variation is not of an excessive order.
Returning now to the heel post |5, there is provided means for locating such post in one of several vertical positions. To this end, the post is slidable in a vertical bore 2|) passing through an enlargement 2| cast in the web portion of bow member I2. A pin 22 is passed transversely through post I5 below the bow member I2, and is freely rotatable in the post. Fixedly keyed to this pin for rotation therewith are a pair .of identical cams or ller blocks 23 and 24. These are mounted on opposite sides of post I5 and each has a plurality of corresponding abutment faces 25, 26, 21, and 28. Each of these faces is located a diiferent perpendicular distance from the axis of pin 22, and each is adapted to be successively seated in abutting contact against corresponding seat portions 29 on the under side of the bow member enlargement 2|. It will be seen that the vertical position of pivot pin 22 and, consequently, of heel post I5 depends upon positioning of one or the other sets of cam faces against. abutment 29. Thus, if in Fig. 1 where the cam 23 is shown as having its face 25 abutting the under side of the bow member, the cam were given a quarter turn in a clockwise direction so that cam face 28 were positioned against seat 29, it willbe seen that the position of post I5 will be considerably lowered. Intermediate positions between these two extreme vertical positions are obtained through proper positioning of the remaining cam faces' 26 and 21. In order conveniently to rotate pin 22 and its associated cams, a handle or lever 3|) is screwed into an enlarged head onv one end of such pin. Twisting movement of post I5 about its own axis is prevented by the means of a downwardly extending rib 3| on the under side of bow member I2. This rib is snugly embraced by the opposed cams at all times.
The upper end of post I5 has detachably screwed thereto'an enlarged head 32, between which and the bow member is located a compression spring 33, which tends normally to urge the heel post I5 in an upward direction and serves to maintain cams 23 and 24 constantly in contact with their cooperating abutments 29. This fhead 32 and spring 33 are preferably located in'a recess 34 which extends downwardly into enlargement 2|.
In operation, assuming the cams to be located as illustrated in Fig. 1, a lasted upper and an outer sole are assembled with adhesive therebetween, and placed beneath toe pad I4 and heel seat member I6, the pad being at this time deated. The pad is then inflated, this inflation serving to expand the pad vertically su'iciently to take up any space between the diaphragm and the shoe or between the shoe and its upper supporting means vand to press the sole firmly against the lasted upper while pressing the entire shoe assembly securely against its supporting toe and heel posts. Various sizes of adults shoes may conveniently be loaded and reloaded with theI press set in this manner. When it is desired to handle lasts of markedly smaller sizes, the press while in unloaded condition is adjusted by giving the handle 3 0 one or more quarter turns so as properly to accommodate the vertical position of heel seat I6 to the smaller sized lasts.
In Fig. 4 there is shown another form of press, wherein the heel post is vertically movable as in the preceding embodiment, and where, in addition, the toe post is movable longitudinally of the -bow member better to accommodate extremely small lasts. The press as illustrated in this figure comprises a base IIII, having a pad cavity II in which is located a pad I |1 which preferably is similar in construction to that used in the previously described embodiment. A longitudinal bow member I I2 is iixedly and preferably integrally carried over base I0. Near the forward end of the bow member is fastened a ytoe post ||3 having a rubber instep pad ||4 ailixed to-its lower end. At the front the bow member I|2 is'shown to be of. an I-beam cross section, including a lower horizontal web 35. The upper end of toe post ||3 is provided with a groove 36 having overhanging flanges 31 which overlie web 35 and, together with groove 36, form a slidable l ed to be screwed into position on the under side ofweb 35 and in front of an enlarged portion 46 of the-bow member casting. Post ||5 fits snugly within the side wallssof housing 4| and between the front wall 42 of this ,housing and the front face 43 of enlargement 46.
The vertical position of heel post |15 is controlled by means-of a cam or filler block |23 whichris positioned between the forks 39 and 40 and is keyed by means of a set screw to a transverse pivot pin |22 which is freely rotatable inl suitable registered openings -in the upper ends of forks 39 and 40. The cam is located between these forks as illustrated, and is provided with a plurality of cam faces |25, |23, |21 and |28, which are located at different perpendicular distances from pivot pin |22 and which are adapted 75 successively to be brought into abutting seating contact against the under faces ofbow member web 35. The total distance between any two opposed cam faces, such as and |21, is equal to the total distance between the opposed cam faces |26 and |28, and corresponds to the distance between the cam contacting abutment |29 and the lower edge of housing 4|,.and also to the horizontal distance between the forward face of wall 43 and the rearward face of wall 42. The cam and its associated post ||5 are thus adapted to be snugly tted into housing 4I with the cam in any one o-f several positions. A retaining strap 44 is adapted to be screwed in place beneath housing 4| and below cam |23, to prevent the latter from dropping by gravity when the press is in unloaded condition, and to hold the cam snugly in place within the housing. The cam may be adjusted to a new position in order to vary the vertical height of post ||5, either by removing this retaining strap and removing and re-inserting the post and cam assembly in housing |4|, or by removing the entire housing and its appurtenant parts as a unit and re-attaching it to the press frame after altering the cam position. Since this adjustment need not be made for each press loading operation, but only at infrequent intervals when it is desired to handle an entirely diiferent type of shoe, no undue inconvenience attends upon alteration of the cam position,v the location of the heel post being of a semi-permanent nature. In order to facilitate control of the cam while it is having its position adjusted in the housing, an outer end of pivot pin |22 is provided with a handle |30, and the sides of housing 4| are suitably slotted or coped as at 45 to accommodate the transverse pivot pin in any of its several positions.
In operation of this form of press, when lasts of larger sizes are being handled, the heel seat` ||6 will assume its uppermost position, and toe post ||3 will be locked in its foremost position as illustrated in dotted lines in Fig. 5. With these parts thus xed in position on the shoe press frame, the press may be repeatedly loaded and unloaded in the manner described in connection with the rst modication. When an extremely small shoe, such as the baby shoe indicated in full lines in Fig. 5, is to be handled, the toe post H3 and heel seat HB are shifted to the full line position shown in Fig. 5, and the press may thereafter be successively loaded with shoes of this smaller type, clamping of the shoe being cared for by inflation alo-ne. The best results will be attained by confining the design of this press to babies and childrens shoes, with a maximum capacity for shoes of about the equivalent ,of size 21/2 in the womens range. However, it will be understood that the particular dimensions of any press embodying the herein disclosed structural 'features are optional, and the appended claims are intended to cover any suitable size range, wherever the context permits.
The first described form of. press shown in Fig. l is primarily intended for operations on lasts of a given category, say womens lasts exclusively. To this end the toe post may be immovable, as illustrated, and the contour of cams 23 and 24 is preferably such as to care for material diierences encountered among various womens lasts. However, it will be understood that this form of press (Fig. l) may, if desired, be equipped with a movable toe post such as that shown in the press of Fig. 4, and/or the cams thereof may be designed to cover a more extensive range,
so that babies', chlldrens and-misses sizes may be handled as well as adults.
It will be seen that there has been provided a structure which is admirably suited to fulll the intended functions.
From the above description it will be understood that certain features of the present invention may be utilized in connection with various types of presses used in the manufacture and repair of footwear. Therefore, while for reasons of convenience the illustrated embodiments of the invention have been confined to preferred types of sole-affixing processes, it is to be understood that the invention is not limited to these types or to use in sole-affixing operations as distinguished from sole-laying or sole-leveling operations. Since certain changes may be made in the above construction and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
