The "ob'ect of the linvention is to provide a simple, e cient and rapidly operating device i, or apparatus which will select the .articles from a large quantity in a holder and .deliver them in a row or series.

.To these ends the vinvention consists in the apparatus substantially as hereinafterl dej scribed and claimed.

Similar reference characters indicate the same `or similar parts in all ofthe views.

A suitable frame or casting 10 is provided with a bearing 11 for a vertical shaft 12 to -the upper end of which is secured the carrier or holder 13 having an annular troughshaped upper surface to receive a mass or quantity of the articles and separators as indicated in Fig. 3. To the lower end oh the shaft 12 is secured a bevel pinion 1,4 pinion 15 on` a" which meshes with a (bevel horizontal shaft 16 mounted in suitable be'arings in the base of the frame. -The shaft is provided with a hand wheel 17 by means of which said sha-ft and, through the gearing described, the carrier or holder' 13 may be rotated. Secured to -rotate with the holder 13 are two spring arms 18, 19, `the former vSpeciicatioii of Lettersflatent. Application file d March 22, 1912,. Serial .o; 685,532: g

or they may be made of separate pieces. v e ,extreme endfof the long arm 19" is 22. The runway'l23 hasaftangential portion which .is/supported'byftheedge 21 of the frame, 'the outer end of saifd runway. being shown as vprovided witha vhole.24,gsaid hole' being simply for the'purp'ose lof ,enabling a Ireceiver for the articles to' be vreadily fitted in alinementwith the delivering end' of the runway. Fromfthe tangential portion, the

runwayis substantially vconcentric with the axis of rotation of the holder 'for nearly a complete circle, the other endv of sai `.run-

way dipping into the h der, as shown inl Figs. 2, 3 and 4. "Thisi ner orreceiving end of the runway is provided4 with a plow or thickened portion 25, the upper edges of which form shoulders' 26, (see Fig. 6). Above the thickened o'r plow end 25 is a vertical relativelyy thin blade 27, and the runway is,A provided with beveled shoulders 2B on opposite. sides of the blade 27. On each side of the blade 27 -is a space or throat 29 .between the under edges of-the runway below' the shoulders" 28 and the upper edges or shoulders 26 yozt the plow 25? An end portion of a barl 30 is indicated in Fig. 7, said bar haying a pin to enter the hole 24 in the delivering end of the runway. Said bar 30 is intended lto merely represent the magazine lcarrier of a tool which is tobe supplied with the articles in the'rotary holder, said articles inthe present case being travelers for spinning rings, such ltravelers being indicated at a in Figs. 3, 4, and 5. rl`he com, Cplete tool having the magazine carrier is described and claimed in my application, Serial No. 685,533, filed on even date herewith.

In the annular trough inthe rotary holder or carrier 13 a large quantity. of the separa'- to'rs 31 will be placed as indicated in Fig. 3. These separators may be balls of different sizes, such as shot. lI do not limit myself to the separators being perfect spheres, 1t being chiefly essential that they shall be of such shape that they cannot become engaged with a runway. Although they are loose in the holder, they are permanent parts of`th'e mechanism or apparatus. 'y

lIn operation, the articles, such as travelers a, are dumped into the holder`13 and said holder is then rotated in the direction of the-arrow in Figs. l and'l. This movement carries the articles and the separators around in suc'h direction that the receiving v1(50'1' plow end of the runway which dips into .the mass will stir/up the articles arid .sepa- -rators and somefof the articles will find their way in succession onto' the blade 27, straddling the latter, and the continuedmotion of fthe-.separators will result in the articles bemgl. worked `along the upper edge'of the blade 27 'onto the portion of therunway beyoud-the shoulders 28. None of fthe articles exceptin those properly positioned can be 20,"4 carried o to the runway because if they 'are not properly positioned, one oivthe other of the inwardly bent-ends 4vof the articles will ride' up onthe'shoulder 28 so lthat that article will be tipped .offs and fallback into-'the 2.5 mass. .Those articles. which ,are properly#I positioned will be carried along with their -inwardly bentends passing -through .the throats 29, and will reach a portion of the runway from -which they cannot become dis- 30 engaged laterally. lThe upward inclination 'of the dipping end ofthe runway is such `that the articles selected 4out from the mass and worked upwardly onto'the runway above the blade 27 will be engaged by the edge of the blade 18 and pushed farther talong up the yincline of the runway, said blade, owing to its light spring nature, -being readily fiexed to follow the upward in-4 clination. :When the blade 18 reaches the 40I highest portion of the runway', it will have become then so curved that it slips 0H and springs back to a horizontal position, leaving an article that has been pushed up by itpresting on the high portion. Then the 45.blade or spring arm 19 follows and pushes along any artiele"6'r `articles that' have been left on the runway-,fthe curved edge20of said arm 19 finally pushing such article or articles outwardly along the tangential por-l tion of the runway, 'leaving them on that portion, if there are but two or three articles assembled near; the outer end, but finally acting through an accumulation of"y such articles to push them off from the 'end and onto the end of the magazine carrier 30,

which magazine carrier can then be transferred to the tool which is to be used to apply the articles. f

. While I have shown spinning ring travelers' as the articles to be assembled and loaded onto a separable carrier, it. is to be understood that the invention is noty limited thereto, -as various other articles', such as j staples for use in a magazine stapling tool e5' niightbe assembled and loaded inthe same manner as described in connection with the ring travelers.

AInfrequently a traveler will be pushed along the runway with another one hooked into and depending from it. Tovprevent such inter-engaged varticles being fed out -or loaded onto thebar 30, the thicker upper edgeof the runway' is cut away orrecessed on bothsides, near its delivery end, as shown at 32. With this provisioinany such interengaged articles will be discharged from the runway x1before reaching the end thereof,

and drop baci( ,into the holder. This is because the lower or hangingilarticle will cngage the inner corner of .the topv edge of the frame andybe held back so that the end of the arm 20fwill dislodge the upper article and both/will drop off from therunway.

Even if additional articles are occasionally pushed olf, the operation of the loaderis sufficiently rapid to quickly deliver the rel quired number.

An especial. advantage of ,the loader as a whole, includlng the separators 31, is that there can never'be an entanglementl of a `large number of the travelers. ln operation 4the plow picks up but one ata time, and n inter-hooking of 'another one voccurs but rarely.

I, claim:

1. A! loading apparatus comprising a holder for the articles, a plurality of loose separators in the holder, a runway having a receiving end dipping into the holder, and means for causing a relative movement of the holder and runway to transfer the articles from'the holder to the runway.

2. A loading apparatus comprising a holder for the articles, a plurality of loose separators in the holder, Aa runway havingy a receiving end dipping into the holder, means for causing a relative movement of the holder* and runway to transfer the articles from the holder to the runway, and

means for pushing along on said runway, the articles that accumulate thereon.

3. A loading apparatus comprising a rotary holder for small articles, alplurality oflo'ose,separators in said holder, a runway having a receiving end dipping into the holder, and a spring arm carried by said rotary holder and adapted to ride along the runway to advance 'the articles toward the discharge end of the runway.

4.' A loading apparatus comprising a rotary member' having a trough-shaped receiver 4-or holder for small articles, a pair of spring arms projecting over said troughshaped holder and .rotatable therewith, a stationary runway mounted over the troughdipping into the holder and having a tangential discharge ends- '5. A loading apparatus comprising a rotary member having a 'trough-shaped! reshaped holder and having a receiving end mames shaped holder and rotatable therewith, a

stationary runway mounted over the troughshaped holder and having a'eceiving end dipping into ythe holder and havingy a tangential 'discharge end, the receiving end of n the runway having means for properly posi-l tioning the articles thereon.

6.` Apparatus for assembling spinning ring travelers, comprising a holder for a quantity of the travelers, a plurality of loose, disconnected members in said holder to commingle with and to separate the `travelers from each other, and an elongated 15 receiverv arranged to dip into the mass of travelers and loose separating members and remove the travelers successively therefrom. In ltestimony whereof l haveaiiixed my signature, in presence of two Witnesses.
