FEEDING MECHANISM FOR. SHOE MACHINERY,

Patented Nov. 24., iota.

Application filed January 28, 1909. Serial No. 474,778.

To all whom it may concern:

Be it known that I, ARTHUR E. JnnRAM, a subject of the King of Great Britain, residing at Leicester, Leicestershire, England, have invented certain Improvements in Feeding Mechanisms for Shoe Machinery, of which the following description, in connection with the accompanying drawings, is

a specification, like reference characters on the drawings indicatinglike parts in the several figures.

This invention relates to machines for operating on boots and shoes and particularly to those machines in which the boot or shoe,

or certain portions thereof, and the tool operating on the same aregiven a relative predetermined movement as a series of operations are performed upon the work, and more particularly this invention relates to the means whereby such relative movement of the work and tool may be attained. A convenient embodiment of this feature of the invention comprises a construction in which the work feeding means is constructed and arranged to move the work bodily into each of its successive operative relations to the tool; such a construction being advantageous in that it simplifies the manipulatlon of the shoe on the part of the operator.

The improvements according to this invention, therefore, have reference to the mechanism by which the work is fed and are designed to render the machine to which they are applied more efficient in operation by lessening the time consumed in placing the work: in'the machine, by increasing the accuracy with which the operations upon the work are performed, and by reducing the length of that portion of the cycle of operations during which the machine performs no useful operation on the work, forexample, during which the machine is brought back to its initial position after completing one series of operations. v

More specifically this invention relates to means for intermittently feeding similar but reversely shaped parts of boots or shoes to the operating tools of a machine for performing a series of operations on the work, such as inserting successively a plurality of fastenings, nails, hooks, eyelets, or the like, and this function is accomplished by providing a feeding mechanism the effective action of which, relative to the operating tools may be reversed for operating upona reversely shaped p211i1.-II1.maCl1lnGS of the class referred to it is customary to feed the work from right to left and thisinvention accordingly, in one of its aspects, contemplates a machine in which the workmay be fed from left to right.

The invention further contemplates a reversible feed mechanism of the intermittent type in connection with means adjust the extent of the feeding movements thereof. It further contemplates the provision of a suitable gage system cooperating with the feed mechanism foraccurately locating'the. work relative to the operating tools for'either direction of feed.-

For purposes of illustration my invention will be described and shownas applied to an eyeleting machine, but from the foregoing it will be apparent that it should be in I10 sense limited to a machine of this particular descriptionbut has a wider range of application. I v

In an eyeleting machine as heretofore constructed the" feed of the work takes place in only one'direction, usually toward the left. to be eyeleted it is placed in the machine in a position to receive the first eyelet at a predetermined point near where the vamp is to be joined to the quarter and the eyeleting operation proceeds until the topmost eyelet of the left quarter is set. The feeding mechanism isthen returned to its initial position at the right side of the machine and the right quarter of the upper put in position. hen the right quarter, however, is to be eyeleted it is obvious that, as the feed is in the same direction as when dealing with the to vary and v left quarter, the work will receive its eyelets v in the reverse order, viz., starting at thetop and receiving them in succession until the bottom is reached. It has been the practice to indicate the position for the reception of the top eyelet on the right quarter by laying the eyeleted leftvquarter. over the blank for the right quarter and pricking a hole through thetop eyelet of the former. This marking through operation has caused considerable loss of time and is further objece tionable in that, should there be any irregularity in the action of the feeding mechanism, the errors in theplacing of the eyelets would be cumulative and the lowest eyelets on the two quarters of the-upper would be ing particularly objectionable owing to their conspicuous position.

One embodiment of the present inven tion, accordingly, is disclosed in an eyeleting machine provided with mechanism for feeding similar but reversely shaped quarters between the eyelet sets. the direction of feed being reversed after each quarter has been eyeleted in such a manner as to render it effective for feeding the succeeding quarter reversely with respect to the machine but similarly with respect to the quarter whereby each quarter is operated on, starting with the lowest eyelet and receiving them in succession until the top eyelet is reached. With such procedure will be apparent that the two lowest and most conspicuous eyelets may be accurately located with respect to the vamp since they are the first to be set respectively in the two quarters. The marking through may be dispensed with and instead each quarter has merely to be properly located with re speet to a gage. One example of the work feeding means to which the invention relates comprises a work engaging element and two complementary mechanisms by which, respectively, it can be actuated in opposite directions and a provision whereby either of said mechanisms may be rendered operative while the other remains in operative. In one form of the reversible feeding device, above described, it has been found expedient to employ a setting die as the work engaging element of the device, the die being actuated by means of a toggle mechanism to engage and disengage the work and associated with the feeding die are two distinct systems of toggle linkage, each system, respectively, adapted to actuate the feeding die in an opposite direction and means cooperating with both systems whereby one may be rendered operative while the other remains inoperative. With the feeding device there may be combined an adjustable gage operatively connected therewith so as to change position, or otherwise be rendered effective, for positioning the work when the feed device is reversed.

A convenient embodiment of this feature comprises an adjustable connection between the gage and its actuator which connection is so proportioned as to give a symmetrical adjustment of the gage about a center line as the feed mechanism is reversed.

1n the operation of an eyeleting machine constructed according to this invention, one of the quarters of a shoe upper to be eyeleted is placed in the machine and in a definite relation to the gage, the feed being in the direction appropriate to the quarter to be eyeleted. Upon the completion of the operation upon this quarter the direction of the feed is reversed and at the same time the gage assumes its new position. To eyelet the other quarter of the upper it is then only necessary to place it in the machine, in the same relation to the gage, symmetrically, as was the first quarter,and to proceed with. the operation of eyeleting in a man.- ner similar to that in which the first quarter was treated.

An eyeleting machine embodying the features of this invention in a convenient form will now be specifically described but as stated above it must not be inferred that the improvements according to this invention are limited to the precise arrangement disclosed or that their application is necessarily only associated with the particular type of machine described although certain details of construction and combinations of parts hereinafter described constitute features of the invention.

In the accompanying drawings :-Figure 1 is a front elevation of an eyeleting machine embodying this invention with parts broken away to show the mechanism by which the feed is effected; Fig. :2 is a sectional side elevation of the machine, looking from the right of Fig. 1, also with parts broken away; Fig. 3 is a detail of the mechanism for transmitting motion from the main shaft to the feeding device; Fig. fl is a plan view of the work table showing the adjustable gage. Fig. 5 is a fragmentary view in perspective of the lower toggle link and some adjacent parts.

The frame of the machine is designated by the reference character 2 and in this is suitably journaled the main shaft 31 driven from the pulley a through the clutch 5 which may be of any desired construction and under the control of the operator through the connection 6. On the forward end of the main shaft 31 is provided suitable mechanism, comp ising a crank or the like, for imparting a vertical reciprocation to the upper set 10. This mechanism forms no part of the present invention and will ac cordingly not be described in detail.

The machine is provided with the usual edge gage 7 and a presser foot 3 which ex-' tends on each side of the upper eyelet set 10 and is arranged to be brought into contact with. the work at the proper time. Other ordinary elements of an eyeleting machine such as the punch, the eyelet hopper, the raceway, the eyelet separator, etc, may be of any desired construction but are omitted from the present drawing for the sake of clearness.

Below the upper set is the work table 90 provided with a horizontal slot 93 through which the die 11 is arranged to act in feeding the work and in setting the eyelets, the slot serving as a guide for the die during its horizontal feeding reciprocations. The die 11 is formed on the plunger 12 which is slidingly mounted in the carriage 13 and is raised and lowered to engage and disengage the work by means of a toggle, one element 15 of which is pivoted upon the machine frame, the other element 17 being attached to the bottom of the diecarrying plunger 12. The toggle is so constructed as to permit its upper element 17 to move laterally with relation to the lower for the purpose of permitting the carriage, and with it the die, to move in a direction to feed the work across the machine. To this end the lower member 15 of the die operating toggle comprises a yoke carrying between the forks thereof a horizontal rod or connecting pin 16, as clearly shown in Fig. 1. The upper member of the toggle is adapted to slide upon this rod as the carriage is moved and.

its upper end is connected to the lower end of the die-carrying plunger 12. The toggle is straightened to raise the die into engagement with the work and broken to disengage it through the medium of the rod 101 which is actuated through any suitable connections from the eccentric 100 on the main shaft. A lug 18 is formed upon the lower toggle member which will engage with an abutment 19 on the frame of the machine and with the under side of the upper toggle member 17 when the latter is in its central or setting position. When the lug is raised and interposed between the die supporting toggle member 17 and the yoke it will constitute a strut to take the thrust of the upper die.

The lower die according to this embodiment of the invention is utilized as hereinbefore indicated to efiect the feeding of the work, and it may be moved at will either from right to left or from left to right whereby the direction of feed may be reversed as required by the work. The mechanism for .operating the feed and reversing its direction will now be described. The lower die 11, formed on the plunger 12 as before stated, is supported by the carriage 13. This carriage ismounted to slide laterally with the horizontal rod 141 working in suitable bearings (not shown) in the machine frame and is kept from turning by the engagement of the die-carrying plunger with the slot '93 in the work table 90. To the carriage, at opposite ends thereof is connected one end of each of the two similar feeding toggle mechanisms, comprising the links 53 and 54 on the right side of the carriage for feeding it toward the right, and

links 63 and 6%. on the left side of the carriage for feeding it in the opposite directi on. These two toggles may be described as floating since neither end of either toggle is connected to a fixed point; one end of each being connected to the movable carriage 13 while the outer ends are pivoted to the links 57 and 67 respectively and carry the studs 55 and 65.

Means for holding stationary the outer end of either toggle, or anchoring the toggle,according to whether that particular toggle is to be operative to feed the work or to be inoperative, comprise the locking levers 58 and 68 each of which is provided with a recess 59 and 69, respectively, shaped to cooperate with the studs 55 and 65. "When the locking lever 58, for instance, is turned upon its center, the recess 59 receives the end of the link 57 carrying the stud 55 and so retains it until the locking lever is turned in the opposite direction to release it.

The locking levers are simultaneously moved to change the feed of the workfrom movement in one direction to movement in v the other direction through the link 70 which connects them and one of them 58 is provided with an extension carrying a handle 73 for convenience in effecting the reversal. It will be apparent that when either of the said locking levers is brought into position to look its toggle by swinging the controlling handle 73 the other locking lever will be turned into a position to free the toggle'on that side of the die.

To insure that either one or the "other feeding device shall be in operation and also to retain in operative position whichever feeding device it is desired to employ, there is provided to cooperate with one of the locking levers the member 71 engaging the spring plunger 72 and so arranged that it will render the linkage 68, O, 58 unstable in an intermediate position but stable in either extreme position.

/Vhen the outer end of either toggle is held stationary that particular toggle becomes effective for feeding the carriage and the work in the direction toward its fixed end, as the toggle is intermittently broken. The toggle 53, 54 is broken to feed the work toward the right, through the medium of the link 56 which is actuated from one arm of the double armed lever 52 mounted on the front end of the rock shaft 20 suitably journaled in bearings 21 in the frame of the machine. The rock shaft is in turn oscillated from the main shaft 31 of the machine through the pivotally supported link frame 32 clearly shown in Fig. 3. The frame is hung on the two radius links 34 and 35 and is provided at its upper end with a follower comprising the two distance pieces and the heads in which are set the bearing plates 36 for the cam 30 mounted on the main shaft. The lower end of the link frame is adjustably connected by the slide 11 to the arm 33 which is fast to the rock shaft 20. When the link frame is actuated upon its radius links 34, 35 by the rotation of the cam 30 the arm 33 on the rock shaft 20 will be acted upon and the rock shaft will receive an oscillating movement and will alternately straighten and break the toggle 53-5et.

To change the spacing of the eyelets the extent of the oscillation imparted to the rock shaft may be varied, and thereby the length of the feeding motion of the die. This is effected by adjusting the point of connection between the link frame and the arm To facilitate such adjustment the center upon which the radius link turns is made movable in a lateral direction by being located on one arm of an elbow lever 37 loosely mounted on the rock shaft. The other arm of the elbow lever passes beneath a cover plate 39 and is provided with a handle 38 by which it can be moved. The plate 39 is provided with adjustable stops, in this case comprising pins ll) and a series of apertures into any two of which the pins may be inserted whereby the adjustment of the lever 37 is temporarily limited in each direction thus affording a convenient means of adjusting the center of the radius link and thereby the point of connection between. the link and the arm 33, in either of two predetermined positions, corresponding with two predetermined lengths of spacing for the eyelets.

A single gage mark adapted for indicat ing the initial lateral. position of the work for either direction of the feed is shown as the arrow 8% on the slide plate 83 (see Fig. i). The plate 83 is slidingly mounted in he work table 90 behind the die and is actuated from the ceding mechanism as the feed is reversed by means of the link 8:2 pivoted thereto at one end and at the other adjustably connected to the slotted extension 80 of the locking lever 58 by the bolt 81.

The adjustable connection between the gage plate and its actuator is so proportioned as to give a symmetrical adjustment about a center line in order that a given adjustment of the connection will insure that the subsequent shift of the gage to one side of a mean position shall be the same as the displacement on the other side. By means of the curved slot in the extension 80 of the locking lever 58 the sliding gage plate 83 carrying the index mark Si can be so adj usted that its extreme positions with. reference to the setting point can be varied to correspond with various sizes of work, with out disturbing the symmetry of adjustment.

Fig. 1 illustrates the feeding mechanisn'i in the middle of a feeding stroke, the direction of feed being from left to right, as the stud is held stationary by the locking lever 58. In operation, after a left quarter has been eyeletcd, a right quarter is placed in the machine, a predetern'iined portion thereof registering with the index mark 84. he machine is started and the rotation of the main. shaft lowers the upper set 10 and simultaneously straightens the die operating toggle 15, 1'7 raising the lower die 11 to meet it. These members set and clench the eyelet whereupon the upper set is withdrawn from engagement with the eyelet; the cam 30 then actuates the lever 52, through the link frame 32 and the rock shaft 20, to break the operative feeding toggle 53, 5a through the medium of the link 56, thereby feeding the elevated die, still in engagement with the inserted eyelet, to the right a distance depending on the extent of the oscillation imparted to the rock shaft 20. il hen the die 11 has reached the right extremity of its stroke the die operating toggle is broken and the die lowered and disengaged from the work. The rock shaft 20 is then oscillated in the opposite direction and through the levers and 56 straightens the feeding toggle 53, 54: moving the lowered die back to its initial position where it is ready to engage the work for a new feeding movement. This process is repeated till the right quarter is completed.

To eyelet the left quarter the handle 73-3 is moved to the left swinging the locking lever 58 out of engagement with the stud and swinging the locking lever 68 into engagement with the stud and thus rendering operative the toggle 63, Gel and in operative the toggle 5 f. One other function is performed by moving the handle 73 as described and this comprises the adjustment of the sliding gage plate 83 carrying the index mark from the position shown. in full lines in Fig. at to that indicated by the dotted lines.

F or eyeleting a new pair of quarters left quarter is placed in the machine in proper relation to the index mark and the eyeleting operation proceeds as before except that now the work is fed from right to left by the feeding toggle 63, 64, the operation of the die operating toggle being unafl'ected.
