My invention relates tomechanism for filling a magazine With sash pins, such magazine being used in machines for applying sash pins and the invention particularly has `for its ob 5 ject to provide an apparatus for automatically accomplishing this desired result.` The magazines Which are tobe filled are long thin bodies of rectangular cross section adapted tocontain a large number of metallic pins 1o stacked one on top of another, side to side,` the pins being usually seven-eighths of an inch long and somewhat less than one-eighth of an inch in Vdiameter and they have one end j blunt While the other end is tapered orfpointi5 ed. The lling of such magazines by hand is a tedious and somewhat costly process since the pins must be placed Within the magazines in one position,`i. e. With their points all pointing in the same direction.`

Therefore it is a primary obj ectof my invention to provide Va mechanism for taking the `pins from a hopper intovvhich they may be dumped promiscuously, aligning them so that `their points Will be uniformly directed 25 and `placingthem in proper position in the magazine.

Further, the invention has for an object to provide an apparatus for the purpose referred to Which Will be simple in its construction,

3G reliable in its operation, inexpensive to manufacture and composed of as few and simple parts as possible. j

Other objects will in partbe obvious and in` part be pointed out hereinafter.

35' To the attainmentof the aforesaid objects and ends, my invention consists inthe novel features of construction and in the combination, connection and` arrangement of parts, hereinafter more fully described, and then 4G' pointedout in the appended claims.

Figure 10 is a detail section on the line 10-10 of Figurel.

In the drawings in which likeV numerals ofl reference indicate like parts'inr all of the fig,- ures, itwill be seen thatupon a; suit-able base l there is mounted a vertical plate 2of preferably nonmagnetic material such asbrass for example; Located on the plate 2" is a hopper 3 into Which the sash pins 52 are dumped promiscuouslyl and from which they are to be taken to the magazine in Which they'are to be stacked. Within theA hopper Buis an` agitator shaft 4 on which are a suitable number of agitators. These agitators may be composed of short pieces of clock spring and serve simply to prevent the pins from packing in the hopper.

The agitator shaft 4 is drivenl through beveled gears 6 from a shaft 7 Which is mounted in suitable bearings on the base l and in the plate 2 and is driven from a. main" shaft 8 by sprocket and chain connections 9 and l0, or pulley and belt connections as may" be found most convenient. The inainV shaft 8 is mounted in suitable bearings on standards 11 projecting upwardly from the base 1 and is driven from asuita-ble source'of'power (not shown) by a belt' takingover a pulley 12'. It is obvious, ofcourse, that if desired a motor can. be directly connected tothe shaftS, but as the method of driving the shaft" 8 is not" an essential part ofthe presentinventionil.- lustration of a `direct connected motor is thought to be unnecessary. j

The shaft 8 carries a disk 13 on which is mounted a pluralityV of magnet-carryingarms 14 (in the embodiment ofthe invention illustrated tivo of such armsare shown diametrically opposite each other); These arms 14 carry electro-magnets l5 at their extremes, Which electro-magnets have their pole ends arranged in close proximity to the plate 2 and are adapted to move over the rear face of that plate as the shaft 8 turns. The hopper 3 is so located on the front face of the plate 2 as to be within the magnetic field of the magnets when they pass behind the hopper, the

. purpose for which will presently be made clear.

In addition to the arms 14 finger carrying arms 16 are secured to the disk 13 and have fingers 17 to engage the levers 30 and 35 presently again referred to.

In order to make and break the magnet circuit at proper intervals a timer is provided. This time consists of a contact carrier disk 1.8 of insulation mounted on the front of the disk 13 between it and the plate 2 and carrying springfpressed contacts 19, one for each set of magnets. These contacts 19 are electrically connected at 20 to their respective magnets, the magnets being in turn grounded to the arms 14 and shaft 8 and through the ground to a source of energy not shown. Mounted on the back of the plate 2 conceny trically with the shaft 8 is an adjustable timer l disk 21 of suitable insulation, in which is imbedded a contact segment 22 of conduct'ng material. The contact segment 22 as well as the non-conducting portion 53 of the adj ustable timer disk 21 are adapted to be engaged by the contacts19 alternately as the shaft 8 is rotated, thus alternately energizing and (le-energizing the magnets 15.

The disk 21 is mounted on the plate 2 by suitably insulated bolts 23 operating in adjusting slots 24 so that the disk 21 can be turned a limited distance for timing purposes, suitable insulating washers 25 being provided on bolts 23. A conductor wire from one pole of a source of energy leads the current to one of the bolts 23, by which it is in turnconveyed to theconducting segment 22 of the adjustable timer disk 21, it being understood that the other terminal of the source Y of energy is grounded.

Within the hopper 3 adjacent its mou th is a thin metallic plate 26, the purpose of which is to serve as an abutment and to insure the pins leaving the hopper with their points always in the samedirection.

27 designates the magazine which has an opening 28 in its side adjacent the hopper and adjacent the upper end of the magazine, the upper end of the magazine being also open.

.Near the lower end the magazine is provided gage the butts of the sash pins 52 and insure the full entry of the pins through thc openings 28 in the magazine 27. The pusher 31 is guided in a suitable guide member 32 which also serves as a guide for the plunger 37 that operates in the magazine 27 through its upper open end. The pusher 31 is held in a return or inactive position by a spring 33 which also serves to return the pusher from its active to its inactive position.

The plunger 37 is operated by means of a shaft 34 having a lever 35 on its back end in position to be engaged by the fingers 17 at proper intervals to rock the shaft and thus rock the forked lever 36 which is secured on the front end of the shaft 34 and engages a stud 38 on the plunger 37. The plunger 37 is also guided in upper guides 39 secured to the plate 2 and on its upward movement has its motion arrested by a suitable bumper 40 that is secured to the plate 2.

The plunger 37 is held in the elevated position and the shaft 34 is returned to its inactive position by means of a spring 41 as shown.

The magazine 27 is provided with a slot 42 in its front face, into the upper end of which projects a pin hold-back spring finger 44. Within the magazine is a pin rest follower 43 slidable along the magazine but held against movement by a yieldable adjusting tension device 45, the tension device being such that more or less retaining friction can be placed on the follower 43 as may be found desirable.

In addition to providing the magazine rest 46 the magazine is also held in place aga-inst the plate 2 by a fixed holder block 48 and a pivoted holder block 49, the latter being swingable out of position to allow for the insertion and removal of the magazine.

5l designates the ground terminal to which the source of energy may be connected to complete the electric circuit for energizing the magnets.

It will be understood that the magazine 27 lies fiatwise against and in contact with the plate 2 in such position that the path of the magnetic field behind the plate will pass the upper end of the magazine in alignment ,with the opening 28.

So far as described it will be noted by reference to the drawings that the operation of my invention is as follows:

Assume pins to have been placed in the hopper 3 and power applied to the shaft 8 and the connection to the source of electric energy made. Now as the shaft 8 turns it will drive the agitator shaft 4 and cause the agitators 5 to churn up the pins. At the same time the magnets 15 will be energized as they arrive behind the hopper 3 and will remain energized until they arrive behind the upper end of the magazine 27, at which time the electric circuit is broken and the magnets behind the upper end of the magazine become deenergized. Since the magnets are energized llO fromithertimethey arrive behind the hopper 3 until.` theyarrive behind the upper end of the magazine 27 they will cause pins tov move fromthe hopper 3 over the face of the plate 2 into themagazine 27 through the.` opening 28. In moving toward the outlet of the hopper3, should the pins be directed butt ends upwardly they will engage the edge of the plate 26. and fall back again. into the hops per. If, however, the points are upwardly directed they will pass over the plate 26 and be carriedthrougli the opening 2S into the magazines Should the timer be not exactly adjusted ito'break the magnetic circuit at the precise instant at which the pinsshall be Wholly inserted within the magazine, or should someof the pins lag sothat the butts of the pins remain projected out of the opening 28, they will be forced fully into the magazine by the action of the pusher 31 which is operated each time a group of pins is carried` into the magazine. Having in sured the complete insertion of the pins in the magazine the plunger 37 moves downwardly to push the partial stack of pins down toward the bottom endof the magazine against the resistance of the follower 43 which, it should of course be understood, is adjusted initially with its upper end in alignment with the lower end of the opening 28. The finger 24 holds thegroup ofpins upward until acted upon by the plunger 37.

L The above cycle of operations is repeated so long asthe shaft 8 revolves and pins are in the hopper 3. As soon, however, as the magazinef 27 has been illedf the operation of the shaft is stopped by the attendant, the holderbloclr 49 is swung back and the filled magazine removed, after which an empty one isfplaced in position andthe operation of the machine continued.`

From the foregoing description, taken in connection with the accompanying drawings, it is thought that the complete construction, operation and advantages of my. invention will be clear to those skilled in the art to which it relates.
