MACHINE FOR OPERATING ON SHOE SOLES.

Application led March 30, 1927. Serial No. 179,648.

This invention relates to machines for operating on soles before they are incorporated in boots or shoes, and more particularly to gaging mechanism for determining the proper relation of the sole to the means which operates thereon. The invention is `herein illustrated in its application to a machine for applying molding pressure to soles, which is et the same general type as that disclosed 1n United States Letters Patent No. 1,004,076, granted on Sept. 26, 1911, upon an application of E. N. Preble. It will be recognized, however, that in its more general aspects the invention is not limited to that particular type of machine nor tomachines for molding soles.

Machines of the above-mentioned type are provided with mechanism for engaging the side edge of the sole to position the sole laterally in relation to the lower pressing or molding form on which it is supported. A welllrnown mechanism for that purpose is shown lin United States Letters Patent No. 1,222,866, granted on April 17, 1917 upon an application of J. J. l-leys. That mechanism comprises an edge gage which moves with the lower form as the latter travels horizontally between its work-receiving position and its operating position, the gage being controlled by a relatively stationary cam at the side of 'the :term which moves it into position over the i'orm when the latter is moved forwardly into work-receiving position and permits it to be moved by a spring laterally awa-y from the term as the latter is moved rearwardly with the sole into t operating position. llllhen the machine is at rest with the lower form in work-receiving position the gage is thus held by the cam in a position over the form.

1t is an object of the present invention to provide a construction such that the sole gage may be readily displaced from its operative i'iosition, for example in order to afford ample room for the removal of the form in a machine of the type illustrated, and also such as to insure against damage to the machine if the gage is not returned to normal position before the machine is next started. As herein illustrated there is provided a construction which permits the gage to he quickly moved to a position out of operative relation to the form and to .its controlling cam without objectionable strain en any' of the parts, target-her with means which in the next succeeding operation of the machine will insure the return of the gage into operative relation to its cam without such interference between the gage mechanism and any portionoi' the machine as to result in breakage or other damage to the machine.

A further feature comprises a novel gage so constructed as to adapt it for convenient use with a widerange oi sizes of soles, the construction shown comprising different relatively displaceable sole-engaging members, one tor use with comparatively large Soles and the other with small soles.

The `above and other features of the invention, including various novel details of construction and combinations of parts, will now be more particularly described by reference to the accompanying drawings and pointed out in the claims.

In the drawings,

Fig. 1 is a view, partly inplan and partly in section, of a portion of a machine in which the invention is embodied;

Fig. 2 is a view in side elevation of the portion of the machine shown in Fig. 1, with parts broken away;

Fig. 3 is a view in side elevation of the gage mechanism, illustrating by broken lines how the gage may be displaced from operative position;

Fig. 1 is a perspective view on an enlarged scale showing the gage in displaced position;

Fig. 5 is a view similar to Fig. t showing the gage after its return into operative relation to its controlling cam; and

Figs. 6 and 7 are views illustrating the use of different gage members with soles of different sizes.

As more ullydisclosed in the above-mentioned Letters Patent No. 1,004,076, the machine in which the invention is herein shown as embodied i s a twin machine having two sets of sole-molding mechanisms only one of which is herein illustrated. Each set comprises a cross-head 10 which is reciprocated vertically on guide rods 12 and 14, and a moldcarrying table or slide 16 which. is reciprocated horizontally on the cross-head. In the construction shown the slide 16 carries a plate 18 which is formed to serve as a drin pan in accordance with the disclosure of United States Letters Patent No. 1,291,880,

granted onJanuary 21, 191), upon an applicathe machine is provided with a co-operating downwardly facing upper form or mold (notshown-.L andthat inthe operation of the mac-hinethe;crossfhead is reciprocated to perormthe moldingoperation and the Slide 16 also :is lreciprocated. to carry the lower form 20 alternately into a work-receiving position near the front of the machine (Figs. 1 and 2) and into yan operating position directly under the .upper form.

`WVhen the lower form 2O is in its work-receiving position with the machine at rest, as `illustrated in Figs. 1 and 2, the operator places a sole upon it inaposition determined 'by a rear end gage and a side gage. The rear end gage is indicated at 26, and need not be further described since vit forms no part of the present invention.` 'lheside gage in the construction Vherein shown comprises two soleedgeengaging members 28 and 30 Varranged to be used respectively in operating on wide and narrow ranges of sole sizes, as more fully hereinafter described. These members are supportedfon a rod V32 the rear end `portion o-fwhich yextends Ythrough an opening in a holder 34 fast on a 1vertical rock shaft 3G mounted in Abearings in-a bracket 38 which is secured to the plate 18. 'lhe gage is thus carried forwardly and rearwardly with the form 2O in the movementsof-the slide 16, and isaiso carried upwardly and downwardly by the crosshead 10, and in laddition it is mounted for swinging movement laterally of the form about the axis ofthe rock shaft 36. A spring 40 connected at one endto the bracket 38 and at the other end to an extension of the rod holder-34tends to swing `the gage away from the form, yand cti-'operating with this spring to Vdetermine the position of the gage is a cam member or plate 42 which is carried -by the Lcross-head 10 :and therefore moves vvertically with the form 2() but is fixed Vagainst movement forwardly and rearwardly therewith'. An extension 44 of thegage member 28 Vengages the cam member 42 and is held against said member by the action of the spring 4Q. It will ,be understood that when the for1n2t) is in Aits work-receiving position the ga ge Vmember V28 or 30, according to which of these members is in use, is inaintainedin operative position over the form bythe cam 42, and that when the form is moved rearwardly to its operating position the gage is swung away from the Vform by the spring 4t) under control of nthe cam, so las to be out of the way inthe Vmolding operation'. When the form is returned to its workreceiving position the gage is returned to operative position by the cam. The general ormuiization of the side gage mechanism :is thus far described is similar to that disclosed in Lei'- ters Patent No. 1,222,856 above referred to. The cam 42 is mounted on a rod 4o which is carried vby the cross-head 1t).` and to vary the position of the gage laterally of the torni for different sizes of soles the rod 4t is moved lengthwise by adjusting mechanism including a rotatable member 48, as also more fully disclosed in said last mentioned Letters latent.

It will be seen that in the removal ot the form 2t), for example to permit the subst itution of a form of different shape, the form must .be lifted in order to detach it from the studs 22 and 24. For purposes of the present invention the side gage mechanism is so constructed that the gage may be conveniently swung to an out-of-the-wuiy position when the lower form is thus to be removed. To this end, the rod 32 is mounted in an opening 50 in the holder 34 which is enlarged or Ilared vertically, as shown in Figs. and 3, so that the rod may be swung upwardly with the gage, without any substantial strain on the rod, far enough to permit the extension le4- and a portion of the gage member 28 to be swung outwardly over the top oi that portion .of the cam 42 which is nearest to the form, as illustrated in Fig. 4 and by broken lines in Fig. 3. The gage is thus displaced out of operative relation to the cam 42. and it will be understood that the spring 4t) tends to hold it in its displaced position.

After placing different forms in the nuichine, the operator will usually start the machine one or -more times before proceeding with the regular molding work in order to determine whether the forms are in proper relation to each other, and in that event he may forget to return the side gage into operative relation to the cam 42. The invention accordingly provides means for insuring against damage to the machine by contact of the moving gage mechanism with a relatively stationary partif the gage is left in displaced position, the construction shown comprising means for returning the gage automatically int-o operative relation to the cani 42 upon the start-ing of the machine. For this purpose there is provided a cani 52 above that portionof the cam 42 which is nearest to the form, the cam 52 being arranged to engage an inclined face 54 on the extension 44 and thus to swing the gage inwardly toward the form 2O when the form and the gage are moved rearwardly in the next operation of the machine. The gage is thus swung inwardly far enough to drop back by gravity into operative relation to the cani 42. so that when the lower form 20 is moved forwardlv again after the forms have separated the gage will be returned by the cam into operative llt) lLlU

Vyielulable relation to the forni ready for nee in raging the next sole that is placed on the torni. llt will be further noted that the cani 52 is in position to limit the movement ot the ,frage when it is swung outwardly to the position illnatrated in lfig. ll.

ller retaining the rod 32 in the holder 3lthere is provided retiring-pressed. detent 55 having' a llehaped end which enters a correeliondingly shapednotch in the rod, as illus trated in Figs. 2 and 3. rlhe detent 55 is thus in response to a null on the rod, so that the eide ,gage may be readily removed troni the machine il' desired. lt will be nnderstood that the operator, itt he desires, may n thus remove the gage .instead ot displacing' in the manner hereinbcliore described. rlhe rod Si), is tapered at its end to facilitate its return movement into the opening,` under the detent, and it is provided With a collar 5G for engaging the holder 34 to limit its return nmvement. lt will be further understood that the spring-pressed detent 55, in addition to holdingl the rod dotachably in Ablame, assiats gravity in swinging the gage dovvn into oper ative relation to the Cain 12 when the age is swung inwardly by the cam 52.

' ln order conveniently to increase the range of the side gage for Widely ditlerent eines ot soles, the `member 8O is mounted :tor turning movement about the rod so that it may be used in place ot the member QS tor comparatively small soles, as illustrated in llig. i", or may be turned up to permit the member to be utilized tor comparatively large soles, as Shown in l? G. il. spring 58 (Fig. 4l) presses the hub portion of the ineinber 30 toward 'the hub porti on ot the member F28 which has a notch GO (Fig. 6) to receive a pin 82 on the member 3G to aesist in retaining this member in operative position.
