FUELING-OVER MACHINE.

To all whom it may concern:

Be it known that I, RONALD F. MOFEELY, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvements in Pulling-Over Machines, 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.

This invention relates to machines for use in the manufacture of boots and shoes and particularly to pulling-over machines.

An object of the invention is to provide novel means for adapting pulling-over machines of the type shown for example in my prior United States Letters Patent No. 663,777 to operate uniformly upon right and left shoes being made on crooked lasts.

In the commercial machine which has been developed from the early construction and which is described in British specification No. 12,304/03 and known to the trade as the Rex pulling-over machine, adaptation for pulling-over shoes on right. and left crooked lasts is made by shifting the heel rest laterally with relation to the pullingover instrumentalities. The shoe is presented with its forepart, which is the part operated upon directly in the pulling-over operation, symmetrical with relation to the median line of the machine. The heel-rest shifts automatically to one side or the other as is required to find and adapt its support ing position to the heel of the particular shoe. When a shoe on a crooked last is thus presented with the median line of its forepart in the median line of the machine there is occasion to adjust only the heel rest and that is done to locate the rear sup ort for the shoe in the median line of the eel part of the last. If, however, it becomes for any reason undesirable to make the relative adjustment of the heel rest and pulling-over devices by a shifting of the heel rest, or wholly by the heel rest movement, then the side grippers should be shifted laterally together to present them symmetrically distanced relatively to the median line of the shoe forepart.

An important feature of this invention consists in providing means for adjusting Specification of Letters Patent.

Serial No. 569,155.

the side grippers of a pulling-over machine I transversely of the machine. In the emibodiment of the invention herein shown it is contemplated that the toe gripper shall remain in constant lateral position in the median line of the machine and that all shoes shall be presented uniformly thereto. With this invention may be employed the novel curved sectional toe gripper described in my prior application Serial No. 445,929 the sections of which can, when the upper is pulled, adjust themselves to any differences which may exist in the edge contour of the last at the two sides of the median line at the toe.

In accordance with a further feature of this invention com rised in the preferred embodiment thereo provision is made for relatively adjusting the side grippers lon fiitudinally of the shoe for rights and Is to. As shown the gripper acting on the outer side of the shoe is set slightly forward and the gripper which is to act on the inner side of the shoe is set slightlybackward at the same time. In the illustrated construction the adjustments laterally and longitudinally are made in predetermined proportion and and are effected by a single adjusting device. This device is arranged in position convenient for manipulation by the operator standing in worln'ng relation to the machine and preferably the adjusting mechanism .8 so arranged that the shifting of the side grippers can, if desired, be effected while the upper is held under tension by the grip er;s.

In the arrangement shown by way of exemplification the side grippers are guided in the frame of the machine and their lateral positions are determined by levers against which they are held by springs. The levers are actuated by opposed wedge faces li y which they are moved laterally in the machines operation, these wedges being adjustable to shift the grippers for sizes. 1n accordance with this invention, the fulcrums of the levers are on a member which is adjustable laterally across the machine andi a screw and hand wheel is provided for adjusting the fulcrum supporting member. This arrangement gives adequate power fbr making adjustment with the upper under tension. By moving the fulcrum support one lever is caused to move its gripper ina shoe whether it be outwardly. The guides in which the grippers move laterally are inclined rearwardly so that with the adjustment of the two side grippers together laterally of the machine they are proportionally adjusted longitudinally but in opposite directions. In this embodiment of the invention also lies a feature of the invention.

A further feature of this invention relates to the positioning of the tacking mecha nisms which fasten the upper pulled over by the side rippers and consists in provision for ad ustment of the side trackers transversely of the machine for rights and lefts. In accordance with the preferred embodiment of this the side trackers adjust themselves automatically to the lateral position of the shoe. Also provision is made for insuring the adjustment before the tack driving operation begins so that both tackers are in proper relation to the shoe before the drivers are tripped. Preferably the arrangement also provides substantial insurance that the drivers at the two sides of the shoe shall be tripped simultaneously and the danger is thus avoided that the early driving of the tacks on one side of the shoe will displace or disarrange in any degree the shoe or the later fastening of the upper at the opposite side. In the illustrated embodiment of this invention in which a further feature of the invention is to be recognized there is provided, between the common actuator and segments for pulling the side tackers inwardly to tack inserting position which are fully explained'in my said prior patent an equalizing mechanism operating automatically to cause a dwell in the inward movement of the tacker which first reaches the shoe and to acceleratethe approach of the other tacker. The tackers in this machine move outwardly from tack driving position to position to connect with the tack supplying mechanism. Means is provided to predeterminethis latter position and insure a uniform starting position from which the opposed tackers move inwardly toward a right or a left shoe.

These and other features of the invention, including certain details of construction and combinations of parts will appear in connection with the following description of the preferred embodiment of the invention and will then be pointed out in the claims.

Figure l is a side elevation of a machine equipped with this invention; Fig. 2 is a horizontal plan and section on substantially line 22 of Figs. 1 and 4; Fig. 3 is a hori zontal, plan and section on substantially line 3-3 of Figs. 1 and 4; Fig. 4 is a front elevation of the side gripper mechanisms; Fig. 5 is a diagrammatic view showing the dissimilarity in the positions of the foreparts of right and left shoes whenthe toe feature of the invention and heel ends are presented symmetrically with relation to the median line of the machine which is indicated by the line ab. The median line of the forepart of an inverted left shoe is indicated by c-b and that of a right shoe by db,' Fig. 6 is a section of the machine operating mechanism on substantially line 66 of Fig. 1.

The machine, as described in my prior patent, comprises a driving shaft 2 from which the toe and side grippers 4, 5, 6 are actuated to seize and pull the upper and the toe and side tackers, properly supplied with tacks, are actuated to insert the tacks for fastening the pulled upper. The grippers and tackers are guided in their movements inwardly and outwardly by guideways in the frame bracket 8 as shown in Fig. 2. The shaft has a cam 10, Fig. 6, which actuates a lever 12 and a rack bar 13 on the lever end to oscillate a pinion shaft 14 and reciprocate a rack slide 15 which in turn drives a slide 16 through a depending lug 18 that picks up a lug 19 on slide 16 during the forward reciprocation of slide 15. The slide 16 has a roll on its front end against which the. toe gripper is held by springs 22 and similar springs hold the side grippers against swivel blocks on the front ends of levers 24 which are engaged by the oppositely inclined faces of a wedge block 25 which is carried upon slide 16. This mechanism may be designated the gripper spreading mechanism, it being understood that the slide 16 is advanced to spread the grippers for the reception of a shoe at the end of each operation and during the next operation it is retracted to permit the overdrawing of the upper to position for fastening it upon the shoe bottom. Means is provided to be actuated by the hand wheel 26 for adjusting the we spread of the grippers for different sizes of shoes. The tacker arms are caused by the slide 15closely to follow the grippers inwardly and finally to engage the grippers and cause them to release the upper when the tackers are in position to fasten it.- To this end the slide 15 acts through toothed segments 30, rack" bars 32 having yielding plungers 34, the beveled ends of which engage slide blocks 35 that have ball and socket connections with the side tacker arms as shown in Fig. 3.- When the inward movement of the side t-ackers is arrested, as occurs by their engagement with the sides of the shoe or with devices which are controlled as to position by the sides of the shoe, the continued movement of the rack bars ,32 compels the plungers 34 to yield and allow relative displacement of rack bars 32 and slide blocks 35 during which shoulders 36 are withdrawn inwardly from under lugs 38 on tack driver 40. This frees the drivers to be impelled downwardly by their dge 25 to adjust the.

wil

' simultaneous Insertion rpoaaao springs contained in the barrels 42, Fig. 4, and acting through levers 4%. Similar controlling means is provided for the front tacker. Further details of these parts may be learned" from said prior Patent, No. 12,304/03.

In accordance with a preferred embodiment of the present invention the sidegripper positioninglevers 24, 24 are fulcrumed on a slide which is mounted for adjustment transversely of the machine to act through the levers for positioning the side rippers for ulling-over shoes on right and eft crooked asts such as represented in full and dotted lines in Fig. -5. For moving the adjusting slide 50 a screw which is held against endwise movement in the frame engages a threaded In on. the slide and has a hand wheel 55. Ty turning the hand wheel the fulcrums of both the levers 24;, .24 will. be moved transversely of the machine and thereby the two side grippers shifted toward the right or the left side of the median line of the machine represented by the mid line in Fig. 4 to pull over a shoe on a left or a right crooked last. The last in the machine in Fig. 4 may be assumed tBo be the one represented by dotted lines in In order toenable the side tackers to adjust for right and 'left shoes an equalizing connection is provided between the two toothed segments-30 which are actuated 'by the slide 15. Thisis shown as comprising a pinion which is freely pivoted in the slide 15 and engages double faced rack bars 62 arranged on ei her side of the pinion between it and the segments 30. This equalizing connection allows a dwell to occur in the closing movement of either side t acker which first engages the full side of the last (or, as here shown, the side clamp thatstands between. the shoe and the tacker) and eifects an acceleration of the advance of theother side tacker. When both side tackers have arrived in the same relation to their res ctive sides of the shoe, both segments be further moved together to withdraw shoulders and cause of tacks on the two sides of the machine. The side tackers are reversely moved outwardly to tack receiving positions which are constant or uniform for all shoes and are determined by the stops 65, Fig. 2, to place the tack conductors 66 carried by the tackers in receiving relation to' the tack tubes 68 of the tack supplying mechanism of the machine.

The heel rest of the machine stands normally in the median line of the machine and the toe gripper which hangs slightly below the plane of the last bottom at the toe and serves by its inner jaw to position the shoe lengthw1se in the machine may center the toe laterally. When the shoe has been prethe driver supporting r the same I claim as operate at the the shoe,

sented in the desired position the operator can adjust, or correct the adjustment of the side grippers laterally of the machine for the croo-kedness of the particular shoe by manipulating the hand wheel 55. This adjustment may be made before, if desired, and it also can be made after the upper has been seized and ulled bythe side grippers. It is to be note that this adjustment is a bodily movement of the side grippers and takes place relatively to and preferably independently of the toe gripper, the normal location of which will remam 1n the median line of the machine, although the toe gripper might have the upper adjusting movements proposed in my prior applications and which form no part c the present. invention.
