' Application filed January 11, 1898. Serial N0. 666,356. '(No model.)
To all 1071,0711, it "um/y concern:
Be it known that I, WILLIAM J. YOUNG, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts,haveinvented certain newand useful Im-f provements in Heel-Compressing Machines; and I'do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
The present invention relates to boot and shoe machinery, and more particularly to machines for compressing and molding heels,
such machines being generally known in ,the
art as heel compressing machines.
The object of the present invention is to produce a heel-compressing machine of simple and compact form and of great power and capacity and to provide an improved'feediug and ejecting mechanism to automatically feed the heel-blank tothe dies and eject the same therefrom after it has beencompressed.
T the above end the present invention consists of the devices and combination of devices which will be hereinafter described and claimed.
The present invention is illustrated in the accompanying drawings, in which- 1 Figure 1 is a front view of the machine. Fig. 2 is a side view of the machine, looking from the right of Fig. 1. Fig. 3 is aplan View of the machine. Fig. 4 is a horizontal sectional view above the table and dies. Figs. 5, 6, and 7 are details of the ejecting mech: anism, to be described; and Figs. 8 and 9 are details of the male die or former.
Similarletters of reference refer to corresponding parts throughout the several views.
In the drawings, A represents the main frame, which may be of any usual or preferred construction, but which for strength is pref-.
' a, in which is mounted the crank-shaft A Upon the main shaft A is mountcd loosely a driving-pulley A which is driven by a belt from any suitable source of power, said pulley being free to havea limited sliding movement along said shaft and being provided with a beveled clutch-face a which is arranged to be forced in contact with a beveled clutchface a, formed upon a wheel A fixedly secured to the shaft A. The pulley A is arranged to be moved toward and from the wheel A to connect and disconnect the frictionfaces a and a, by any suitable mechanism, that shown in the machine ofthe drawings comprising a lever a which is fulcrumed at a to one of the rear frames a and which is provided with a yoke or fork a, which loosely engages the hub of the pulley A" and which at its lower end is pivotally connected at a with a link ct, which is in turn pivotally connected at a with an arm a, rigidly secured tothe rear end of a rock-shaft a, which is mounted to turn in suitable bearings (r in the frame and which at its front end is provided with a foot-treadle (1 whereby said shaft o may be rocked to straighten and bend the toggle formed .by the arm a and the link a, to thus through the lever a move the pul- .ley A toward and from the wheel A, whereby to control the movement of the machine. Upon the opposite end of the main shaft A is a pinion a", which is in gearing with a gear (1 which is fixed upon the end of the crankshaft A whereby motion is communicated from the main shaft A to said crank-shaft A Connected to an arm a of the rock-shaft a tis a link a which is connected to a hand-- brake c which may be of anynsual or pre-' ferred construction and which is arranged to engage a brake-pulley a, mounted upon the,
main shaft A. (See Figs. 1 and 2 Arranged to slide vertically along suitable guideways Z7, formed along the inner side of the front frame a, is a bed'or table B, which upon its upper surface carries a suitable tread-surface-molding plate 19* and side-compressing dies D, as will be fully described. The bed or table B is arranged to be moved vertically by a toggle, it being p'ivotally con nected at b with the upper member b of the toggle-levers b and b the lower member b ,of the toggle-levers being fulcrumed at?) to the frame a. glcs b and b are provided with recesses D The meeting ends of the togin which the head (1 of the connecting-rod 12 fits and engages the shaft b the opposite end of the connecting-rod I) having a suitable bearing Z2 fitted upon the crank b of the crank-shaft A The above-suggested arrangement is such to the bed or table B toward and from the upper end of the frame 0.
Upon the bed or table B is arranged the tread-face-molding plate 19* and the sliding side-compressing dies D, each of which has a curved face 01, arranged to act upon and mold one-half of the sides and back of the heel, as usual in machines of this character. die D is removably secured by any suitable means, as by the plates 61, to the sliding diecarriers d", which are arranged to have a sliding movement along the upper surface of the bed or table 13 in a guideway formed by the upwardly projecting flanges cl, and such movement of the die-carriers may be produced by any suitable mechanism, that shown in the drawings being arranged and operating as follows:
D represents a pair of levers which are fulcrumed at their upper ends at d in suitable recesses a* of the frame Ct, the lower ends d of said levers being free and resting upon the upper surface of the bed or table B, outside of the die-carriers (1 whereby upon the 'upward movement of the bed or table B the free ends d of the levers D may slide inwardly along said bed or table and engage the diecarriers CF, and upon a further upward movement of said bed or table force said die-carriers d and the dies (1 toward each other to cause the dies to compress and shape the sides and ends of the heel-blank which may be between them.
In order that; the dies D shall not be opened to the full extent of the movement of the ends 01 of the levers D along the bed or table B, but shall only open sufficiently to permit the placing of the heel-blank therein in order to insure the proper positioning of the heel-blank and to avoid any possible displacement of the heel blank upon the closing of said dies, the dies D are preferably disconnected from the levers D and are arranged to be moved by said levers only in one direction to close said dies around the heel-blank, said dies being moved in the opposite direction or in a direction to open them for the reception of a heel-blank by suitable springs d which at one end are secured to said dies and at their opposite ends to the bed or table B, the die-carriers d and the ends d of the levers D being provided with recesses (i in Each caused by the upward movement of the bed or table B, said ends are preferably rounded, as shown in Fig. 1, and engage rounded recesses d formed in the outer faces of the diecarriers d (See dotted lines, Fig. 1.)
Cooperating with the dies D is a male or heel-seat die 0, which is preferably mounted for a yielding vertical movement in its holder and also to have a vertical adjustment toward and from the die D in order to accommodate the dies for difierent thicknesses of heels. The heel-seat die 0 is carried upon a stem 0*, which stem is held for vertical movement within the screw-threaded holder 0' by a pin 0 the upper end of the stem 0* being acted upon by a spring 0 which acts to normally press the heel-seat die yieldingly toward the dies'D, whereby said heel-seat die 0 will contact yieldingly withtlie heel-blank before the dies D have entirely closed thereon, so that if said heel-blank has been improperly positioned the dies D may move it to one side or the other to center it, and the yielding contact of the heel-seat die C with said heelblank will insure the proper holding of said blank in its adjusted position until the final pressure of the dies takes place.
The vertical adjustment of the heel-seat die C is obtained by the vertical movement of the screw-threaded holder 0, said holder being surrounded by a sleeve 0 which has an internal screw-threaded bearing fitting the threads of the screw-threaded holder 0, and said sleeve is mounted to rotate in a bearing 0 of the frame a, it being supported in said hearing by a head 0 formed on its lower end, which rests in a bearing 0 formed in a plate 0 which is secured to the under side of the frame a by bolts 0 The turning of the sleeve 0 causes a vertical movement of the screw-threaded holder 0 and a vertical adjustment of the heel-seat die 0, the holder 0 being provided with a squared head 0 which fits in a squared bearing 0 in the plate 0 whereby the holder 0' is prevented from rotating upon the turning of the sleeve 0 The sleeve 0 is arranged to be turned by a hand-wheel 0 which is connected to a shank 0 which in turn is connected to the sleeve 0 by a pin 0. In order to compress the breast edge of the heel, there is provided a breastplate 0 which is pivotally supported bya pin 0 upon the front of the head cl", passing down in front of the heel-seat die 0 and being normally pressed outwardly by a spring 0 The lower end of the breastplate c is provided with a beveled finger 0", whereby upon the upward movement of the bed or table B the lower end of the finger 0 will engage the inner edge of the plate 0 and move the b'reastplate 0 toward the front of the male die 0, so that its lower end will be received in the recess 0 and when the dies are finally brought together the breastplate 0 will be forced against thebreast of the heel to impart a molding pressure thereon.
The heel-blanks are automatically fed be tween the dies D to be compressed, and after being compressed are automatically ejected from the dies D from the same side of the machine at which they were fed into the dies, any suitable chute or deflector being used to convey the compressed heel-blank to a barrel or other receptacle placed to receive them.
The mechanism for feeding the heel-blanks to the die D in the machine of the drawings is preferably arranged as follows:
E represents a table, which is fixedly secured upon the front of frame a in any suitable manner, as by the bolts e. The table E is slotted, as at e, in line with the dies D, and along this slot travels a feeding-plate 6 said feeding-plate having an upturned end 6 or otherwise formed to engage and push the heelblank forward between the dies D. The feeding-plate e is connected by means of a link 6 with a lever 6 said lever beingfulcrumed at (2 to the under side of the table E. The lever e at its outer end is pivotally connected with a rod e which at its opposite end is pivotally connected at c with one arm 6 of a bell-crank lever, which is fulcrumed at e the opposite arm 6 of said bell-crank lever carrying a cam-roll e arranged in the path of a tappet e held to rotate with the crankshaft A whereby a rotation of the shaft A will by means of the tappet e impart a quick oscillation to the bell-crank lever and by means of the rod 6 and the lever e impart a quick movement of the feeding-plate e toward the dies D, to thus feed the heel-blank along the table E between said dies. In or.- der to quickly return the feeding-plate e after the bell-crank lever has been released by the tappet a, there is provided a spring 6 one end of which is connected to the lever e and the other end to the fixed frame'of the machine. Y
In order that there shall be no danger of breakage in case the forward movement of the feeding-plate e should meet an obstruction, the rod e is made in two sections, one section being provided with a sleeve 6 in which the other section is arranged to slide,-
and within said sleeve e is a spring e which bears against the-section of the rod sliding therein. By this construction provision is made for lost motion and all danger of breaking the parts by an obstruction in the path of movement of the heel-blank-feeding plate which would stop the advance of said plate is obviated.
The heel-blank to be fed between the dies D is placed upon the upper surface of the table E in front of the feeding-plate 6 with its breast edge against the front of said plate,
and in order to insure the correct feeding of the blank a guide-plate e is adjustably secured upon the upper surface of the table E along and parallel with the line of movement of the feeding-plate c, said guide-plate being guide-plate a" may be adjusted according to the size of heel being fed.
In order that there shall be no liability of the heel jumping over the back of and out of the dies D as it is fed thereto, there is pro vided a detent finger or plate f, which isarranged to have a horizontal sliding movement back and forth over the die-cavity between the dies D, the forward end of said detentplate f being arranged to engage the upper surface of the back of the heel-blank as it is fed intoposition between the dies D. The detent-plate f is arranged to slide in a guideway f, formed in a plate f which is bolted to the top of the back flange 01 and it is reciprocated by any suitable means to cause its forward end to be projected over the dies D upon a lowering of the bed or table B and to be drawn back upon the upward movement thereof out of the way of the heel-seat die 0.
In the machine of the drawings the detentplate f is actuated by a finger or leverf pivoted at f to the back of the bed or table B, and the upper end of said fingerf is arranged to be acted upon a cam f fixed to the rear face of the frame-a upon an upward movement of said bed or table B to withdraw or pull back the detent-plate f, and a suitablev spring is arranged to force said detent-plate forward, as shown in Fig. 4, upon the downward movement of the bed or table B.
The heel-blank-ejecting mechanism of the machine of the drawings is arranged to discharge the compressed heel upon the downward movement of the bed or table B, and said mechanism is preferably arranged to ejectthe compressed heel from the dies D from the same side at which the heel-blank was fed to said dies, and this ejection of the compressed heel preferably takes placealittle in advance of the time of the complete downward movement of the bed or table B, so that the compressed heel will be discharged from the dies at a point above the plane of movement of the heel-blank which is being fed to the dies D, so that thecompressed heel as it is ejected from the dies will be conveyed out of the machine by a deflector or chute (not shown) and will not interfere with the heelblank which is resting upon the table E preparatory to being fed by the feeding-slide 6 The heel-blank-ejecting mechanism of the machine of the drawings comprisesa reciprocating ejecting-rod h, which is arranged to have a movement back and forth along a guideway it, formed in an arm h*, which is secured to the rear side of the bed or table B in any suitable manner, said ejector-rod passing through an aperture 7L formed in the rear flange (11 in line with the medial line of the opening between the dies D, whereby when the dies shall be opened, as shown in Fig. 4, to release the compressed heel the ejector-rodvh may be moved forward and strike the back of the heel, forcing it out of the dies D.
The ejector-rod h is preferably arranged to be-moved in one direction along the guideway h toward the dies D by means of a spring, whereby it will impart a sharp and quick blow to the back of the heel, knocking the heel from the dies D, and the ejector-rod is moved in the opposite direction against the tension of the spring and locked in its outer position under spring tension until the downward movement of the bed or table B shall have reached a point where it is desired to eject the compressed heel. To secure the above-suggested result, the ejector-rod h in the machine of the drawings is connected by means of a link it to an arm or lever 71, said link 77, being pivotally connected at one end to the ejector-rod h and at its opposite end to the arm or lever 77., as clearly shown in Fig. 6 of the drawings. The arm or lever 71 is fixedly secured to a rock-shaft 71 arranged to rock in suitable bearings h, carriedby suitable brackets 71 secured to the rear face of the bed or table B. The arm h is moved toward the bed or table 13 to cause the ejector h to knock the compressed h'eel from the die D by a suitable spring h one end of which is secured to the arm 71 and the other end to the back of the bed or table B, and to move the arm 'h in the opposite direction to retract the ejector h the shaft 7L5 is projected beyond its bearing It at one end (see Fig. 4) and is provided with a finger hi, fixedly secured to the end thereof, said finger 71 arranged to be engaged by a pawl 71 held in the path of movement of the finger W, as the bed or table B moves up and down, whereby the shaft It will be caused to rock in its bearings h and move the arm 7L4 outwardly against the tension of the spring lbs to retract the ejector 71 as shown in Fig. 6. The pawl h is carried by an arm 7t, which is fixedly secured to the rear face of the frame a in .po sition to engage the finger 7L9 upon a downward movement of the bed or'table B, and, as shown in Fig. 7, the pawl 7& is pivotally mounted in a recess formed in the top of the arm. h by-a pin 71 whereby said pawl h is arranged to swing upwardly to permit the free passage of the fingerh? upon the upward movement of the bed or table B, but the pawl 71 is prevented from swinging downward,whereby upon the downward movement of the bed or table B it will engage the finger 77/ and rock the shaft 71 to retract the ejector h, as before explained. The ejector is held in its retracted position under the tension of the spring 71 by a suitable locking-dog or detent, which is arranged to be tripped to release the ejector mechanism at a suitable point in the downward travel of the table B, the pawl and its tripping mechanism being arranged and operated as follows: The locking-dog 71 is carried by a shaft h which is mounted to rock in suitable bearings h formed in the arms or brackets 71", and in a bracket h, which, as in the case of the brackets 771 is secured to and movable with the bed or table B. The locking-dog 772 is arranged to engage a notched collar 7?, carried by the shaft h said dog being pressed against the collar h by a spring 71.", connected at one end to an arm 71 rigidly secured to and projected from the shaft 71, the spring h causing the shaft to rock in its bearings h and holding thelocking-dog 71 in position to engage the notch in the collar h, as clearly shown in Fig. 6 of the drawings, whereby the arm 7% and the ejector 7t will be held in their retracted position under the tension of spring 7L8, as before described.
In order to trip the locking-dog h upon the downward movement of the bed or table B to release the arm 71, and the ejector h, the shaft is projected beyond its bearing h in the bracket h, as clearly shown in Fig. 4 of the drawings, and upon the outer end of said shaft is fixedly secured a finger h arranged to be engaged by a pawl h pivotally supported in a recess in a vertical arm or standard 7t, which is secured to the top of one of the side frames of the fixed frame of the machine in such position that upon the downward movement of the bed or table B the finger 77/ will be engaged by the pawl 71/ and cause a slight rotation of the shaft h in its bearings, which acts to discharge the lockingdog h from the notch in the collar 7L on the shaft 70 and permit the spring 71,8 to quickly move the arm 7L and the ejector 7L toward the dies D and to deliver a sharp and quick blow upon the heel in said die to remove it therefrom.
The above-described arrangement is such that with the ejector h retracted, as in Fig. 6, the bed or table B will be moved vertically to cause the dies D and O to compress the heel, and upon a downward movement when the table B has reached the point where it is desired to eject the heel from the diesD the arm h will beengaged by the pawl 71 to slightly turn the shaft h and disengage the locking-dog h from the notched collar h, permitting the spring it to move forward the arm h and the ejector-rod h to deliver a sharp quick blow upon the heel and discharge it from the dies D. Upon the further downward movement of the bed or table 8 the finger 72 upon the end of shaft h will be engaged by the pawl h to turn the shaft 71 and retract the arm h and the ejector to again set the same,-the spring 77, causing the lockingdog to engage the notched collar h and hold the ejector retracted, as above described. Upon the upward movement of the bed or table B the arms 71 and 71, pass the pawls/r and It, said pawls lifting and permitting the passageof the arms h and 77, without disturbing the ejector, and after the arms h and 77 have passed above the pawls h and 77, they will drop back in position to release and reset the ejector, as before described.
The operation of myinvention is as follows: The bed or table B being in its lowest position, as shown in Figs. 1 and 2, and the dies D being open, with the ejector mechanism set as shown in Fig. 6, the heel blank is placed upon the table E in-front of the feeding-plate c with the breast edge'of the heelblanks bearing against the edge e of the feeding-plate e and with one side of the heelblank bearing against the guide-plate e". The operator now places his foot upon the treadle a thus causing the pulley A to be moved toward the wheel A and the clutchfaces a and a brought into contact, whereby motion is imparted to the driving-shaft A and to the several parts of the machine. The rotation of the driving-shaft A acts through the pinion a" and the gear (L18 to impart a rotation to the crank-shaft A and through the medium of the link b 'and the toggles b and b to impart a vertical movement to the bed or table B to carry the bedor table and the 'dies and heel-blank thereon toward t-heheelseat die 0. Just prior to the vertical move ment of the table B the tappet e has acted upon the roll a, carried by the arm a of the bell-crank lever, which through the connecting-rod e oscillates the lever c to move forward toward the dies D the feed-plate e feeding theheel-blank resting upon the table E into the opening between the dies D, the back portion of the heel-blank being engaged by the forward end of the detent-plate f, as
- compress and shape the same.
hereinbefore described; After the tappet (2 has passed the roll e the spring 6 acts to quickly return the bell-crank lever and the feed-plate e to their normal condition, as shown in Fig. 4 of the drawings. As the bed or table B moves upwardly the ends of the levers D move along the top of the bed or table and engage the outer sides of the diecarriers 61 and in the further upward movement of the bed or table force the die-carriers toward each other against the tension of-the springs d to bring the dies D forcibly against the sides and back of the heel to As the bed'or table approaches the heel-seat die 0 the beveled finger c comes in contact with the inner edge of the plate 0 and moves inwardly the breastmolding plate 0 to cause it to enter the recess 0 and the continued upward movement of the bed or table Bcauses the heel-seat die 0 to come in contact with the upper surface of the heel-blank, and at the extreme limit ,of the upward movement of the bed or table B the heel-blank will be forcibly compressed between the heel-seat die 0 and the upper surface of the bed or table B or the tread-molding plate 12* thereon and the sidecompressing dies D and the breast-plate 0 During the upward movement of the bed or table 13 the rod f strikes the inclined camsurface f and is swung outwardly against the tension of its spring, retracting the detentplate f and withdrawing its forward end from its position over the recess between the dies D.. The continued rotation of I the crankshaft a now acts to break the toggles b and b and to lower the bed or table B, and as said bed or table is lowered the heel is relieved mit the spring 71.8 to throw forward the ejectorrod h, which strikes the back of the heel a sharp and quick blow, ejecting it from between the diesD, as before described. This action of the ejector takes place before the bed or table 13 has reached the limit of its movement in the downward travel, and the finished heel is arranged to be guided from the machine bya suitable deflector or chute. (Not shown.) As the bed or table continues its'downward movement and immediately after the ejector has discharged the heel from the machine the finger h of the shaft 71. will be engaged by the pawl h torock the shaft 77. and retract the ejector 7t against the tension of the spring h said ejector and the arm 7L beingmoved to the position shown in Fig. 6, where they will be held by the locking-dog li which is drawn into engagement with the notched collar h by the spring h". \Vhile the bed or table B has been traveling downward the operator has placed another heelblank in position upon the table E ready to be fed into the space between the dies D, and the operation, as before described, is again repeated.
Having fully described my invention and its mode of operation, I claim as new and desire to secure by Letters Patent of the United States i 1. In a heel-compressing machine, the combination with the vertically-movable table, of side compressing dies mounted thereon, a heel-blank-feeding device, and means to actuate the same to feed a heel-blank between the side compressing dies at one level, and a heel-blank-ejecting device and means to actuate the same to eject the compressed hee1- blank from between the side-compressing dies at a dilferent level, substantially as described.
