HEEL-.Mame MACHINE.

To all 'whom it may concembA Beit known that I, JAMES L. RAKERD, a citizen of the United States, residing at Kansas City, in the county of Jackson and State making heels for shoes', saidanethod and prodterial'has ardened. 'By omitting the uct resulting therefrom., also of my invention, being described but not claimed'hereinafter. The .ob'ject of my invention is to provide a machine or anlparatus by which heels for shoes maybe rapi y and economicallymade. My invention providesa machine in which the lifts for a plurality of heels may bequickly assembled in a pile cemented together.

11e soassembled ma be compressed and held c en'ressed unti the cementin inaayers of cementing materialv between sections of the pile intended to form the heels, the sections mav after compression be readily separated. f layers of ceinenting material alternate between all of the. layers of lifts, after' compression the 'ile is transversely 'cut into sections to forni t e separate heels.

This invention provides a holder for receiving the lifts, a vessel for containing the cementing material, preferably paste, a plunger carrying a pad arranged to enter the said vessel, and means for reciprocating the plunrcr, so that the'lifts may be fed into the older in a pile of alternate layers of lifts and ceinenting material.

.Means are provided further by which the' cement-ing material applyin(i means may be rendered ino ierative when desired, whereby the lifts of adijaccnt sections will not have be.- tween the'm a layer of the ceineiitiiig material.

The invention provides further a holder having means by which the lifts are assein bled in a pile -with one set of edges in aline.- inent with each other.

Other novel 'features of my invention are hereinafter fully described and claimed.

F ig. 14 is a' side elevation of a pile of the character shown in Fig. 12, after the said pile has been subjected to the shaping operation following the coiiipiessing and hardening of the pile.

Similar characters of reference denote similar parts;

The apparatus comprises :i holder forreceiving in a pileI the cemented lifts,- the merlianism by which the lifts are cemented andv fed into-the holder, i nd'the. compressing detvice by means of whit h the pile is compresr ed and retained in a compressed cenditior until Two vertical guides 7 j a lower ends rigidly secured to the bars 5 and BEST AVAILABLE CPY i the paste `or other cementing material has become hard or set.

I will first describe 'the holder and the sup- 'pgrt .on which it is placed when the lifts are ingfed into it x-On a tablel, or similar supporting device, is mounted a flatv plate 2 provided with a central hole encircled by a tubularv projection 3, extending downward through an ,opening rovilded therefor in th table 1.; The lift ho der comprises a vertical body 4 of horseshoe shape in cross` section, two horizontal bars-5 and 6 being secured across the open front of the holder of the body 4 adjacent its u per and lower ends. Ihave their upper and respectively, Four vertical guides 8 are disl posed-within the tubular bo y4, each ide 8 mounted'upon the inner ends o two radially movable screws 9 which extend through the walls of the body. Upon each screw 9 is mounted a coil spring 10, one end of which bears against the adjacent guide'S,

j the other end bearing against the inner side I soY of the casing or body 4. The parts, just described are clearly shown in Figs. 3, 5 and 8. The dis osition of the guides 8 is such that Flifts, when forced upward through the h the. hilder casing or body 4, as described hereinafter, the forward edges of the lifts -will be forced against the rigid guides 7, thus retaining'th'e forward edges of the lifts in 'alinement` vThe inner.- sides of the lower ends of the guides? and 8 arebeveled so that the'lifts may be easily forced from below between sai guides. p

By means of the following described mechanism, the easing 4 of the lift holder is re- Vleasably4 secured to the base plate 2. -A

U Shaped an le bar 11 has its horizontal flan e secure to the to of plate 2 and encirc ing the opening tlnough said plate. The lower end of the casing 4 is' fitted in the vertical flange of the plate 11 and rests upon the upper side of plate 2 with the inner wall of the casing 4 in alinement with the inner wall ofthe tubular projection 3 of plate 2. vIn the outer wall of casing 4 are provided horizontal'holes adapted each to receive a horizontal pin 12 slidably mounted in holes provided in two vertical arms 13 of a bracket aving a downwardly extending rejection- 14 secured to the vertical flange o the angle Each pin 12 is encircled by a coil spring 15,'one end of which bears against one Vof the arms 13, the other end bearing'against a collar 16 secured to thepin 12 between the arms 13. The outen end of each pin 12 is provided with a head by which the pin is grasped and withdrawn from the hole in casing 4 a ainst the pressure of s ring 15,

when it is esired to remove the ho der from the plate 2.

Four upwardly and inwardly inclined spring plates 1.7 are'secured et their lower ends to the inner periphery of the ttubular projection 3 in alinement respectively with the guides 8. Extending above and intermediate the spring lates 17 are three similar .jection 3 is mounted on the up er side of a U vshaped plate 21 secured tot e inner e- 'riphery of the tubular rejection 3. he upper side ofplate 20 is ush with the lower side of an opening 22 provided in the forward side of projection 3 vand through which the lifts are fed one at a time.

A reci rocative plunger is provided for forcing tiie lifts one at a time flatwiseupward to a position' between the spring plates 17 and 18 and between the guides 7 `and 8. The' preferable plunger mechanism comprises the followlng' described parts. The plunger comprises a rod 23 having at one end an upwardl extend right angled central stem 24 w ich exten s through a central opening in a cross shaped plate 25 to the respective arms of whichare secured the lower ends of four pins 26. Holes 27 are provided in the late 20 to receive the stem 24 and pins.

26 of t e lunger. The other end of the rod 23 is split ongitudinally, the two arms thereof denoted by 28 being clamped upon opposite sides of a horizontal rock shaft 29 by bolts 30 having nuts'31', the bolts ext-ending through transverse holes in the arms 28 above and below the rock shaft 29, the nuts 31 bearing against one arm and the heads of the bolts against the other arm 28. The rock shaft 29 is mounted in bearings 32 .sec red to the upper side of the table'l, and as secured to it at one end a crank by which the shaft may be rocked when it is desired to reciprocate the plunger.'

For applying cementing material, such as paste, to the liftsv 19, the following described parts are employed. A slidable plate 34 is provided with five holes 35 through which extend the stem 24 and pins 26 of the plunger. A'coil spring 36 encireles the stem 24 and has its lower end bearing upon the plate 25 and its opposite end bearing against the plate 34, said spring normally holding the plate 34 in the upper positionv shown in Fig. 3 and Fig.,1. Upon the plate 34 is mounted a eementing device comprising preferably a pad of felt 37 also provided with holes through which the stem 24 and pins 26 may -pass during the operationof feeding a lift.

To the underside of table 1A is secured a vessel 38 adapted to contain the cementing material, such as paste. A vertical slot 39 is provided in the table 1' to receive the rod moved to the position shown in dotted line 37 will be forced through the perforated plate lift, which prior to this vin Fig. 1 the pad 37 is immersed `in -the paste.

/ment of the plunger .is continued in the same the plate 2.

vcollar 46 secured to the adjacent rod 42.

As the crank 33 is moved to rock lthe shaft 29 in the proper direction lthe pad 37 is carried upward 'by the plunger and strikes against the under side oV the thin plate 20, which is shown exa gerated in thickness in Figs. 3 and y 1, but whi'ci in practice is thin enough so that the paste carried on the upper side of the pad openings and against the under side' of the o eration has been placed by hand through tllfe opening 22 and upon the -thin plate 20. If now the movedirection,the plate 20 and the lift that at the time is carried thereon will be forced up ward between the spring plates 17 and 18 until the upward movement of the plate 34 and pad 37 is arrested as will be described later. The movement of the plate 34 and pad 37 being stopped, and -the'plunger still having an upward movement, the plate 25 will carry the pins 26-throughthe holes in the plate 34 and pad 37 and the lift will be detached from the pad and will be carried by the stem 24 and pins 26 to a position inwhich the lift will be above the upper ends of the spring plates 17 and between the spring p ates 13, the latter by their pressure forcing the lift 19 forward against the inner sides of the rigid guides 7 of the lift holder. At this time the crank 33 will be swung fin the `opposite direction, thus rocking the shaft 29 so as to'swing the rod 23 downward, thus swing ing the plunger and the pad 37 and pl'atc 34 into the position shown in dotted lines in Fig. 1, in which position the pad 37 will :be immersed in the paste.

VThe mechanism for-arresting the upward movement of late 34 and pad 37 is composed of the fo low-ing described parts. Two right angled bars 40vhave their vertical arms slidable in holes provided in the -plate 25j the upper ends of said rods beingsecured to the plate 34. At opposite sides of the `projection 3 in plate 2 and table 1 are provided two holes through which extend two lhollow cylinders 41, saidlcylinders beingsupported by In the closed lower end of each cylinder 41 is provided. a vertical fhole in which is slidably mounted a rod 42, the upper end of which is vertically slidable in a verticaltube 43 slidable vertically in a hole provided in the closed upper end of the cylinder 41. lnl each cylinder 41 is a coil spring 44 which encircles the rod 42 vand has its upper end bearing upon a'collar-45 encircling and secured to the adjacent tube 43, the lower end o1- the spring bearing yupon a The two rods 42 are positioned 4so that when the plunger is swung upward the horizontal arms of the right angled bars-40 will. strike the projecting ends of said rods 42 and will force said rods and the tubes 43 and springs 44 upward to the-position shown in Fig. 10.

The collars 45 will now strike the Aclosed up per ends of the cylinders 41, thus arresting the upward movement of the tubes 43am causing the coil springs 44 to push against the collars 46, thereby resisting the upward movement of .the rods 42 and rods 40. The two springs 44 are strong enough to overcome the coil spring 36 on-the stem 24 and the upward'movement of the plate 34 and pad 37 will be arrested as before stated, the pad,

however, having fby this time applied thev paste to the under ilat side of the lift 19 which is being fed.

It is desirable, when thel different sections which are to form heel sections in the pile of lifts are not to be cemented together, to arrest theupward movement of the pad 37 before it arrives at a position in which it can apply paste to the li t which forms the lower end of a section in the pile. To do this it is necessary to arrest the upward movement of the tubes 43 before the collars 45 strike the closed upper' ends of the cylinders. Td effect this the following mechanism is prof vided., Referring particularly to Figs. 2 and 3, 47 and 48 denote respectively two horizontal barspivoted before and to the rear respectively of the cylinders 41 to the upper side of plate 2. A horizontal bar 49 is pivotally connected at its ends to the forward ends of the bars 47 and 48, and at its forward edge is provided with a handle 50 by which the bar 49 may be moved lengthwise to swing the bars 47 and 48 to and from posi tions in vwhich they will be immediately above the tubes 43. By swinging the bars 47 and 4S to the position shown in Fig. 4, the said bars will obstruct the upward movement of the tubes 43 and the collars 45 will oppose the upward movement of the springs 44, thus arresting the upward movement of rods 42, 40, and plate 34 and pad 37 before the pad 37 has reached a position in which it can apply the paste to the lift 19 which is in position on p ate 20 for being fed. The plunger plate 25, pins 26 and stem 24 however will continue the upward movement and the lift will be forced into position upon the upper ends of spring plates 17.

In operating the invention the lifts 19 are fed one at a time through opening 22 upon plate 20, and after each insertion of a lift upon the plate 2U, the crank 33 is rocked and the pins 26 and stem 24 forces the lift into position upon the upper ends of the spring plates 17 and between the spring plates 13 which force the lift against the forward guides 7. On the forward side of the proj ection 3 is secured the lower end of a vertical indicator bar 5]' which has attached to it adjacent its up er end a cross bar 52. When the lifts are feif the bar 49 is positioned as shown in .of the holder.

Fg.`2, thus permittin -the tubes 43 to pass through the closed en s of the cylinders 41 to the position shown in Fi 10 at 'eachreci rocation of the plu'n er. aste is, thus app ied to each lift 19 unti a lift appears opposite the bar 52. The bar 49 is then swung so as to position the bars 47 and 48 over the tubes 43, as shown in Fi 4. The tubes 43 are thereby arrested in t eir upward'movement, 'thus ar' resting the pad 37', as already described', and preventing the pad applyin paste to the lift now to be fed. Afterthis ast lift has been fed, the bar 49 is shifted again to the position shown in Fig. 2 and the operations repeated until the ylift which Awas not pasted arrives opposite the bar 52, at which time the bar 49 is again shifted so as to arrest the pastingoperation.

The operation above described is repeated until the holder casing 4 is nearl full of lifts 19 formed in a pile composed of eel sections having alternate layers of lifts and cementing material, there being no paste between the ad'acent lifts of each two sections. The holder is then removed with the pile of lifts from the base plate 2 by withdrawing the pins 12 from the holes in the casing or body 4 The holder is then placed on the horizontal base 53 of the compressor, said base having a boss 54 on its upper side ada ted to bear upon the lowest lift 19 in the hol( er. Secured to the base 53 at their lower ends are two vertical bars; 55, the upper ends of which are secured to a cross bar 56 having a vertical central threaded opening in which is fitted a vertical rotary screw 57, the upper end of which has secured to it a horizontal hand wheelv 58, and the lower end having secured pivotally to it a plate 59 adapted to rest upon the u permost lift 19. With the parts so positioner the screw' 57 is turned so that the lifts 19 are tightly compressed. .The screw is then left in this posi tion until the paste has set or hardened, after which the holder is removed from the compressor, the cemented lifts removed from the holder, and the holder is replaced in position on late 2 in the position shownin Fig. 1.

' he cemented pile, made as described, is shown in Fig. 13.' The sections not being cemented to each other,l they will be readily,

separated from each other.

y If it is desired to cement all the lifts to- A gether, as shown in Fig. 12, the bars 47 and 4S are left in the position shown in Fig. 2, in which position cach lift will have paste applied to it during the feedingr operation.

After the pile has been formed in the holder andv compressed, as already described, the pile may be severed, as indicated by the transverse dotted lines in Fig. 12, by any suitable cutting means.

If it is desired to shape the sides off the heels, this may be done before the sections are separated from each other by employing any suitable cutting' apparatus which will form the heel sections, as indicatedby the f Wave lines in Fig. 14. The sections may then be separated by any suitable means where the dotted lines appear in Fig. 14.
