LIFT HOLDING AND DELIVERING DEVICE FOR HEEL-BUILDING MACHINES.

Application filed March 25, 1916.

To all whomit may concern:

Be it known that I, JOHN E. MITCHELL, a citizen of the United States, residing in the city of St. Louis and State of Missouri, have invented new and useful improvements in Lift Holding and Delivering Devices for Heel-Building Machines, of which the following is a specification.

' This invention relates to the art of heel building, and has special reference to the construction, arrangement and operation of a plurality of magazines, each of which is adapted to contain a stack of lifts, with meansfor delivering simultaneously a lift from each magazine. One of the objects of the invention is to provide a series of magazines, each of which is open at its rear side, aml is inclined in a direction away from the open side to permit of a staclcof lifts being supported therein; a further object is to provide a series of magazines for lifts, each magazine having but one side wall, and

the wall of each magazine after the first serving as a retaining wall for the lifts in the preceding magazine; a further object of the invention relates to the provision of means for simultaneously ejecting a bottom lift from each of the magazines; a further object relates to the provision of a plurality of magazines, each magazine comprising a single side wall, thelifts being retained between the side walls of adjacent magazines, and which magazines are adjustable vertically and horizontally; and a further object of the invention relates to an adjustable stop-plate for preventing displacement of the bottom lifts in the magazines on the return movement of the ejecting means. Other objects of the invention relate to details of construction and to combinations. arrangements, and operations of parts, all as hereinafter more fully set forth.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a view in side elevation of a machine constructed according to my inven tion;

Fig. 2 is a plan view of the machine viewed in the direction of the arrow 2 of Fig. 1;

Fig. 3 is a view in front elc 'ation viewed in the direction of the arrow 3 of Fig. 1; and

of Fig. 2 and viewed in the direction of the arrows.

Referring now to the drawings, the numerals 1, 2, indicate, respectively, two side frames which are provided about centrally of their upper side with rectangular depressions 3 which are adapted to receive the opposite end portions of a cross beam 1, the ends of which project beyond said side frames, as shown more clearly in Fig. 2. The said side frames are also provided with open-sided recesses 5 at their top and forward side which receive a cross beam 6. the ends of which also project beyond the sides of the side frames, as shown more clearly in Figs. 2 and Between the cross beams i and 6 I provide a table section 7, the upper side of which is flush with the upper side of the cross beams and (3. At the rear of the cross beam 4 I also mount on the top of the side frames a table section 8, the upper side of which is flush with the upper side of the cross beam 1, as shown more clearly in Fig. 4. The side frames 1 and 2 are preferably of cast iron and are secured to bolsters 9. The upper portion 10 of these side frames is inclined forward or toward the operator, as indicated in Figs. 1 and 1, and the top of the machine, comprising the table sections 7 and 8, and the cross beams 4.- and 6. are correspondingly inclined. Secured near opposite ends of the cross beam 4, respectively, are two standards 11, 12, between which e.\'- tend two rods 13, l-l, located. respectively. at the top and center of said standards. and having their opposite ends secured therein. The numerals 15 indicate a series or bank of magazines, each of which. as shown by Fig. 2, is L-shaped in cross section, and affords a front wall 16 and a side wall 17. The front walls 16 of the magazines lie substantially in the same plane. Mounted on the front wall 16 of each magazine is a bracket member 18. Each of these bracket membeiis is provided toward its opposite ends with a slot 19 through which extends a screw-' threaded bolt 20 passing through the front wall 16 of the magazine. A binding nut 21 is mounted on the screw-threadial end of each of said bolts. Each of the brackets 13 is provided toward its upper end with a I'ccesscd seat 22. which is adapted to receive the rod 13. The mnneral -22) unluntcs a clamping plate which is loosely mounted on Hill a set screw 24 having screw-threaded engagement with the bracket 18 about centrally thereof. Said clamping plate has offset ends 25 which are adapted to engage the re spective rods 13 and 14, and, when the set screw 24 is turned home, it will draw the seat 22 of the bracket 18 into engagement with the rod 13 and the lower portion 26 of said bracket into engagement with the rod 14, whereby each of the magazinesis supported on the rod 13 and is held 111 firm, fixed position by engagement of the bracket 18 with said rod and the rod 14. By loosening the binding nuts 21 the magazines 15 may be raised or lowered to remove their lower ends a greater or less distance from the table of the machine to provide a throat or passageway 27 for the passage of lifts under the magazines. The standards 11 and 12 and the magazines 15 supported thereby are perpendicularly disposed wlth reference to the top, or table, of the machine, and hence are inclined forward or toward the operator, as shown in the drawings. The side walls 17 of the respective magazines are parallel to each other, and, as clearly shown by Fig. 2, the several stacks of lifts 28 are retained between the side walls of adjacent magazines with their rounded ends resting against the front Wall 16 of each magazine. In order to accommodate lifts of varying sizes I provide for a Y lateral adjustment of the magazines 15, and

this is accomplished by simply loosening the binding screws 24 and slidmg the magazines 15 over the rods 13 and 14 to the desired position, when the binding screws 24 are again'turned home to clamp the magazines in the. adjusted positions. By inclining the magazine 15 in a direction away from its rear open side, which, in the present machine, is in a direction toward the front of the machine, I am enabled to retain a stack of lifts in each magazine without the necessity of using a back wall. Were the magazines vertically disposed a back wall would be necessary, as otherwise there would be constant danger of a stack of lifts tilting backward and falling out of the magazine. The use of magazines having their rear side openso as to leave the edges of the lifts exposed possesses also av distinct advantage, in that the lifts may be inserted in the magazine by a lateral movement at any desired point in its height without the necessity of the operator having to reach to the top of the magazines for this purpose, which would be the case were the magazines inclosed on all sides.

lVith the magazines supplied with lifts, it is one of the objects of my invention to provide for simultaneously ejecting the bottom lift from each of the magazines so that they can be pasted and assembled into a heel-blank with facility by the operator.

For this reason I eject the lifts so that they will rest on the fixed support or table at a point which is unobstructed by the magazines, that is at the side of the bank of magazines. To accomplish this ob ect I slidably mount on the table portion 8 at the rear of the machine an ejector plate 29, which is of a width to extend across all of the magazines and of a thickness to work in the space or throat 27 provided between the lower ends of the magazines and the table or top of the machine. I also provide means for reciprocating the ejector plate 29 to eject the lifts by a movement which is lateral with respect to the direction in which the series of magazines extends. I find a convenient way to effect the reciprocation of the ejector plate to be as follows:

The ends of the said ejector plate are extended beyond the top of the machine,

of throw-levers 30, the lower ends of which throw-levers are secured in crank arms 31 having hubs 32 mounted on opposite ends of a shaft and fixedly secured thereon as by means of set-screws 34. The shaft 33 is mounted in suitable bearings in the standards of the side frame members and fixedly secured at one end centrally of said shaft is a foot lever 35 which projects forward beyond the machine so that its free end is within easy reach of the foot of the operator. The foot-lever 35 is normally held upward against a rod 36, acting as a stop, by means of a coil spring 37, one end of which is secured to the foot-lever and the other end to a rod 38, extending between the frame members 1 and 2, and secured at its ends therein. A suitable stop 39 is preferably mounted on the front bolster 9 for limiting the downward movement erator the throw-levers 30 will be moved forward, carrying the ejectorplate 29 under the magazines 15, the former engaging the straight breast-edges of the lifts and ejecting the lower lift in each of the magazines and moving them out upon the top or table of the machine within easy reach of the operator. The pasting device need not be in the path of the lifts when ejected.

To build the heel-blank the lifts first have paste applied thereto and then are assembled in a suitable heel-forming device. I have shown in the drawings a pasting device comprising a receptacle 40 removably mounted at one end on a support 41 secured to the under side of the cross beam 6 and at its other end on a beam 42 extending between the side frames 1 and 2 at the rear thereof. Mounted in hearings in the side frames of the machine is a shaft 43, one end of which is provided with a pulley 44,. by

and are apertured to receive the upper ends means of which it may be rotated. Secured on this shaft is a pasting roller #15 which is provided with annular circumferential recesses 46 through which extend two parallel bars 47 which are secured at opposite ends, respectively, to the cross beams 1 and 6. 1he roller is constantly revolved by the pulley 44.- and takes up the paste supplied to the receptacle 40. In practice the upper edges of the bars 47 are substantially flush with the periphery of the roller 45, and as'the paste used is relatively thick, the layer of paste adhering to the roller will project slightly above the upper edges of said bars. In practice, therefore, when one of the lifts 28 is 'moved by the operator over the bars 47 its under side will be thoroughly and evenly supplied with paste by the roller 4:"). The particular pasting mechanism shown herein, and above briefly de-- scribed, forms the subject-matter of a separate application for patent, (Ser. No. 86,663, filed March 25, 1916).

Secured centrally of the cross beam' 6 is a suitable heel-blank former 48 which may be of any preferred construction, and, as indicated in Fig. 1, after the lifts have been drawn flatwise over the bars 47 and supplied with paste by the roller 45 they are raised on edge and pressed into the former 48. \Vhen a heel-blank of the desired height or thickness has thus been built up the heel-blank is removed and placed in a suitable press or holder until the paste is set. I have illustrated the heel-blank former 18 as a conventional means for enabling the lifts to be assembled. As a matter of fact, and as shown in a companion application (Ser. No. 86,614 filed March 25, 1916), I provide for moving the heelformer containing the heel-blank to a position opposite a holder of indeterminate length and forcing the successive heelblanks into said holder. .Such operation, however, forms no part of the present invention, and the heel-blank, after, being assembled in the former 48, may be removed by hand and placed in a fiat press, or otherwise treated, as above indicated.

As shown by Fig. 2, the lifts in the respective magazines successively increase in size, and as the four lifts are ejected from the bottom of the magazines in the manner above described the operator will build up the heel-blank by assembling the lifts in the order of their size, beginning with the smallest lift. The table operates as a support to hold the lifts stationary after they are ejected and guides the lifts when they are being assembled by hand. It will be understood, however, that all the lifts may be of the same size and that if necessary the magazines may be suitably adjusted laterally to accommodate varying sizes of lifts by loosening the set-screws 24: and

tion, as previously described.

In order to prevent the lowermost lifts from bein carried backward and out of the magazines in the return movement of the ejector plate 29, I provide means independent of the ejector means, consisting of a bar 49 having its opposite ends 50 bent at right angles and. provided each with a slot 51 by means of which the ends 50 are adjustably secured to the respective standards 11 and 12 by the use of set-screws 52. The bar 19 located at the rear of the magazines 15 and extends across the same, as shown in Fig. 2, in close proximity to the rear sides thereof, preferably being angularlydisposed or inclined relative to the rear side of the magazines, as shown by Fig.4, so as to have its point of closest a ppreach to the magazine opposite the throat 27, and thereby avoid the possibility of offering an obstruction to I the downward movement of the lifts in the event one or more of them should projeztt slightly beyond the others. It will be apparent, especially from an inspection of Fig. 1, that this bar rests on the ejectorplate 29, and hence should the ejector plate 29 in its returnmovement tend to carry the lowermost lifts resting thereon backward with it, said lifts would engage the lower edge of the bar 19 and be prevented from such movement. In its return movement the forward edge of the ejector plate 29 is, as shown by Fig. 1, carried to, or slightly back of the bottom edge of the stop plate 19. By loosening the set-screws 52 the bar 19 may be adjusted toward or from the magazines according as the sizes of lifts used are varied. If the smallest size lift is materially smaller in size than the largest lift, it will also be apparent that the end of the bar 19 opposite the magazine containing the smallest lifts'can be moved inward farther than the other end of said bar, so as to bring the first-named end of the bar substantially as close to the smaller lifts as the opposite end is to the largest lifts. In other words, the bar would then be given an inclined posi tion to the magazines instead of extending parallel to the rear sides thereof as shown in Fig. 2.

I have shown only five magazines accommodating four stacks of lifts. It will be apparent, however, that a greater or less number of. magazines may be used according to the height of the heel-blanks to be built. It will also be apparent that if the number of magazines in position on the machine is greater than the number of lifts required for a particular height of heelblank being built, that liftsneed only be supplied to the required number of magazines, and the remaining magazines be left empty. T "t is to say, the invention contemplates simultaneously ejecting the lowermost lift from each of a plurality of magazines, whether such magazines be the total number of magazines employed or a less number.

In practice I find it decidedly advantageous, in stacking the lifts in the magazines, to insert the lifts in the magazines round side foremost. In this way a large number of lifts can be taken in the hand and inserted at one time, as the rounded sides of the lifts engaging the edges of the side walls of the magazine will direct the lifts into the magazine; whereas, should it be attempted to insert a number of lifts through the rear of the magazines with their flat or breast side foremost. one or the other of the corners of the lifts will invariably engage one or the other of the walls of the magazine and be turned sidewise, and this will result in distorting the position of other lifts held in the hand, so that it becomes impossible to insert the lifts in the magazine. Furthermore, when so positioned in the magazine the lifts will be discharged with their axes extending in the same direction, and with their rounded side toward the operator, who without changing their position, moves them over the pasting device and then raising the rounded end of each lift with his thumb, places it in the heel-former with its fiat side resting upon the bottom members 93 thereof. Should the lifts be delivered flat side foremost and moved over the pasting device in that position, the operator could only with great difficulty lift the rear rounded side of the lift by the use of his fingers, besides being constantly liable to have his finger come in contact with the pasting roller.
