UNITED SHOE MACHINERY CORPORATION, or riirERsoN, NEW JERSEY, A ooRroi RATION OF NEW JERSEY.

Be it known thatgI, FRED '-V.. HART, a'citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in F eed Mechanisms; and

' I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertai'ns yto make, and use the same. i i

This invention relates to, mechanism for feeding a succession of articles vor blanks from a magazine or supply-holder.

y zo

In feeding articles successively from a supply, it is sometimes necessary that certain of the articles,.as fed, occupy positions, relative to the articles fed before and afterward, which are-different from the'relative positions occupied by the articles'in the vma gazine or supply-holder. This is particu! larly true in the 'case of wedge-shaped heellifts. Such lifts-,owing to the fact that they taper from the rear 'edge to the front edge,

can not berstacked loosely in a magazine unless substantially half ofjthe lifts be `vturnedA in a position opposite to that of the other lifts, so as to `balance the thick edges of half of the lifts against the vthin'edges of the other lifts. Accordingly, it has been -proposed to,y stack Vsuchwedge-lifts in alternatinvpositions, that is, with the thick edge of each lift adjacent the thin' edge ofthe next lift in the stack. VWhen lifts are fed from such a stack, however, if it be desired thatthey all be fed in similar positions with respect to their thicker and thinner edges, as

is necessary in feeding the lifts automatically to machinesin which they are utilized in the manufacture of heels, special provision is necessary for turning the lifts al1- to similar positions either after, or' in conv nection .with,the operation of feeding them.

The object Vof the present invention is to produce a feed-mechanism, of simple construction andoperation, bywhich articles may be f ed successively and may, at4- the same time, beturne'd so as to bringthem into a required relative position'other than that in which they are stacked and arrangedin the magazine or supply-holder; More pars larger scale.

"speemation of Letters Parent.` Patented' sepefi., 1920; Appii'catidnniei December 14,' i916, ffseriai N0."13 6',935 Y l acuiariy, the object or the; inveatiofi'istoi produce a mechanism bywvhich wedge-` shaped heel-lifts, stacked in alternatingpositions, may; be fed,'one by vone,"all"inl the same positionwith respectto their thicker o and thinneredges.

To the foregoing end, it'visl'proposed to Y the invention, the articles are turned while 'in the magazine, prior` to ltheir discharge therefrom, but 4the invention, kas defined Ain the claims, is of suliicientV breadth to include turning the articles either before, afterf'orl i vduring the discharge thereof.;`

A machine for 'feeding'articles in the man- Vnerjust set forth is lillustrated inthe accompanying drawings, inwhich VFigure -1 is'fa elevation; and'liig. 3 is a'partial'rse'ction on the line 3f?) in Figi, but on. a slightly Vrh@ invention is iiiustaaed embodied plan-view of the machineg'fFig. 2 is a sideinV a machine adapted particularly for: -feeding wedge-shaped or tapering blanks, such as lthe wedge-lifts'used' in themanufacture of heels. The blanks are stacked ina magazine which comprises Ifour parallel n'ieinbers,

bars. V,These membersclare mounted, inV ver# 12,' and are fixed thereon by means of brack- 14, 6, 8 'and 10, havingthefform` ofiangle'- ets 14;f secured to the turntable by binding- 4 screws.v gated openings in the brackets, as shown vin the magazine-members maybe adjusted toblanks of different sizes.

The blanks arel placed' in the Y magazine with their-lateral edges against thellanges` v e 10o 16 on [the magazine members, and these flanges are cut away at different levels,'as

The screws project through elon'b shown in Fig.Y 2, in accordancewith thedi1 5.,

rections in which the successive blanks are- Y tical aXis, after thev discharge ofeac'h blank from the bottom of the stack, the blanks, if expelled from the magazine in the same direction, 'will all bedischarged with their thick edges to the left, as shownV in Figs. 1 and 2, and with their thinner. edges to the right..

4The turntable 12 is fixed on a vertical shaft 18, which is journaled in a sleeve 20 ldepending from an upper plate 22. This plate constitutes a part of the frame of the machine, and it is supported, in horizontal position, by uprights 24 which connect it rigidly with a horizontal base-plate 26.

The Weight vofthe magazin-e and its contents, and Vof the'turntable, is supported by a ball-bearing 28 inclosed within the sleeve 20.V`v The turntable and the magazine are actuated by rotation of the shaft `18,` and forV this purpose a rgear 32 is ViiXed to the flower end of the shaft. This gear copervartes ,with a mutilated pinion S4, which is `fixed on a power-shaft 36, journaled vertically in bearings on the'frame- plates 22 and 26. The pinion 84 has the number of teeth necessary to turn the gear 82 through halfy of a rotation at leach engagement, andthe pinion is rotated constantly by theV powershaft, this shaft being provided with n a sprocket-Wheel 38 which is connected, by a sprocket-chain 40, with any suitable source of power. voperates withan'automatic machine for oplVhere the feed-mechanism `'co erating upon the articles fed,'the Vchain is connected with the mechanism. of such machine, sogthatthe feed-mechanism may be actuated in timed coperation therewith.

- Aftereachhalffrotation of the shaft 18, itsV movement is arrested, .and l'urtherv rotation of Vthe turntable isprevcnted, until the next engagement of thefgears, by` a spring-pressed detentV 42 which slides into "engagementwi-th one or the other of two hametr1callyarranged recesses in the turntable, as shown in Figs. 1 vand 2. l

The blanks `are expelled from the magazii-ne by means of a Vplunger in the form Aof a thin strip 44 of sheet-metal. .This plunger lis vliXed, at one end., to .a block 46 which slides toward and from the turntable in a g-uideway 48 formed inthe frameplatc 22,' and the amplitude of movement of the .block is such as to cause the end. ofthe plunger to engage the edge of the lowermost blank in the. magazine and expel this blank from the magazine, the operativeend of the plunger reaching the position shown in dot-and- For this purpose a cam 50 is fixed on the power-'shaft 36, and ythis cam engages a roller 5201i an arm 54 whichprojects integrally `from a sleeve 56. This Vsleeve turns -on a rod 58.1'ixed vertically .in the frame- Y i plates. A second 60, projectingV integrally from thesleeve 56, is connected, by

a'link 62, `with an arm 64.v The arm 64 isA lintegral withal sleeve 66, which turns upon a second rod 68 fixed vertically in the frame" plates. A secondY arm 70, integralvwiththeA .sleeve 66, is connected, by a shortlinkf 72,

with the slide-block 46. Y

Then the projecting part of thecam 5() engages the roller 52, it a-cts, through the connectionsjust described, lto advance the slide-block and the feed-plunger, and since the powerfshaft moves in the direction of thearrow in F v1, that is, counter-.clockwise as shown'in that figure, this movement ofthe feed-plunger y,occurs shortly ,after a half-rotation of the magazine and While the latterA is'V stationary.

The return-mo`vement o' and its actuating mechanism is produced-by 'a spring 7 6, of which oneend is Vattached to Y vthe arm While the other end is attached to a pin .7 8, which is secured, for conven- 1ence,'1n the rod 68. After .each returnf movement of theVfeed-plunger, the mutilated pinion 34 again acts to. impart a half- Y rotation to the magazine. y v

The feed-plunger acts with suicient rapidity to /eject each blankrom the framethe feed-*plunger Y sov plate 22,v and the blank may'then bereceived in avchute or conductor 77 ,of any suitable form, forf,.conveying it, in the position isn which itis dischargcchto the ma- A,chine (not shown)rin which the blank is 't0 be utilized.

Y lVh'ile the inventionhas beenp'articularly Vdescribed ,as` embodied in machineffor feeding wedgehaped heel-lifts or blanks otsimilar form, it will be apparent that it vmay beused in connection with Varticles of other forms and charatters, wherever, in

.flact, it is. necessary that the articles as ted `be turned to positions other'than the rela- I tive positions whichthey occupy in the magazine or,supply-holder.V It will also be apparentthat theinvention is not 4limited to `the details of construction -and operation .of the illustrated embodiment thereof, but that it may be embcdi-ed invariousvother i'crms within the scope of the following claims.
