The lower end of the chute, at 29, (Figs. 5 and 7) opens into a chamber 2O formed in the upper portion oit the frame. this chambei.' being of substantially `rectangular 'form and having its bottom wall provided with a hardened wear plate 31. This wear plate may be secured to the :traine by means of screws 32 or in other desired manner. it being understood that while such weainplate is desirable, it is not essential to the operation of the mechanism. Tlu lett hand side wall of: the chamber 30 is also provided with a hardened plate, as indicated at 32 (Figs. 5 and 11) such plate being secured in position by means of screws 33. The plate 32 is provided with a centrally arranged, cuplilre cavity, (Fig. 11'). Extending through the adjacent portion o'l' the trame, and through the plate 32 is al cylindrical lbore which opens into the cavityB/t and is concentric. therewithL Movable longitudinally the bore is a plunger member 36, the end. of which is provided with a wear plate 37' secured thereto by means oit a screw 38. This wear plate in normal position projects into the cavi-ty 34, as indicated for exampie in Fig. 11, the outer surface of such wear plate lying substantially in the plane of. the outer surface of the plate 32. The plunger 536 is. carried by, and as herein'illustrated, may be integral with a lever 3'?, such lever being provided with spaced ears 38, having pivotal engagement with the lower portion of the chute 27. The lever 37 as thus arranged is rockable in a vertical plane, the bore being of a diameter suiiicient to permit the plunger 36 to move longitudinally therein while oscillating vwith the lever 3T. The lever 3T projects downwardly below the plunger 36 and is provided with a tail 40.

The bell crank lever also comprises an arm l5 whichl extends laterally outward, and which is prowith which engages the outer end of the coil 'spring 1.7, the opposite end of which is secured to an eye-bolt Q28 fixed in the upper part oit the trame. lli/lith the parts thus arra gedV the spring l? tends to rotate the bell clank lever in a clockwise direction, thus carrying the pin 4.4i into engagement with the tail l0 and thereby normally maintainino' the plunger 36 with its inner end proiec 'ng into the cavity 34.
The wall ot thc chamber 130 opposite the plate Si?, is .formed by the surtaceA-.l olv a leve;l device 50, such level.' device being pivote( to oscillatev about the axis ot a stub shaft 5l @extending transversely from `trout to` rear of the traine and secured in a f,ui.t='.ible opening in one ci the vertical y Ytrarne members, (Fig. 5). 'This lever device is preferably constructed as indicated in Vlili 5 and i', comprising parallel web membe between which is arranged 'an antiiriction. roll .mounted upon a shalt 53 extending through said web members and se=- cured therein. The roll 52 is arranged for engagement with the wiper cam 22 previ ously described, lnterposcd between one oli the vertical members oit' the trame and the lever 50 is a compression spring 5d, such spring serving normally to maintain the cam roll in engagementwith the cam.
horizf'n al bore 55 extends through the i per part oi the lever 50'opening through. io surface 49 into chamber S0 such bore be- ,V in substantial axial alignment with the bore 35 previouslyY described. Within the bore 55 is arranged a plunger sleeve 56. A plate is secured to the upper part of the lever as by means of a bolt or screw 5S and serv to cover the right-hand end oitlv the boire 55, as viewodin Figi. lllithin the sleeve 56 a secondary flange or 'tec/ler ba r 59 is arranged for longitudinal sliding movement, thatend olf said bar adjacent to ehamher 30 normally being flush with the end of sleeve 56. This bar is provided with a stem 30 which is surroiuided'by a vcoil spring 6l., such spring beingv seated within a cylindrical cavity in the sleeve 56 and having one end bearing against an annular shoulder in said cavity. rthe opposite end ot the spring bearsr against the. plate 57. The? stern 60 ot,V
the leeler bar passes out t n'ough an opening in theplate 5i and .is provided with a transverse opening through which passes a pivotA pin 62 whereby such. stem is pivotally secu red to a lever arm The lever arm 63 is pivoted at 6d to a bracliet carried by the upper part of the lever 50, and at apoint below the pivot pin 62 the lever o3 is provided with an adjustable stop' pin 66, the inner end ot which is engagcable with the outer surface of the platey 5"?. rit its lower extremity the lever is provided with an offset contact member 67 and is also. provided with an eye-bolt 68 to which one end .the lower surface ot the table 4.
of a spring 69 is secured. The opposite end of the spring 69 is :tast to a pin 70 secured to the lever member 50 such spring tending normally to move lever and bar 59 to the lett. Projecting`ldownwardly from the sleeve 50 is a lug 7l lin which is arranged an adjustable stop pin 72 engageable with an adjacent surface of the upper part of lever member 50.
Extending transversely across the Vtrame olI the machine, and through suitable bearings therein is a rod 73, the right-hand end olf which, :is seen in Fig. 8 is arranged 4tor engageinent by the contact element 67. At its opposite end the rod 73 is arranged for contact with an arm 'Tlo't a bell crank lever 75, such arm, it desired, being provided with. an adjustable contact pin 76 'for engagement by the end ot suchv rod. This bell crank is secured. to a shaft 77 pivotally mounted in the brackets lil., `suchbell crank having a rearwardly extending arm provided with an opening 7S to which is connected the lower end oif a spring 79, theupper end of such spring being secured to an eye bolt 80 (Fig. 3) tast in the upper part of the frame. Fixed upon the shafts d2 and 77, respectively, are the pawl levers 8l and 82, respectively, (Fig. 9) said levers ending in tooth ` members 83, 84. The lever 82 lies in a vertical plane immediately behind the planeoic. the `lever 8l, such levers cooperating with parts hereinafter to be described.

This rod is also slidable' in a guide opening in a bracket S6 depeinlingI 'from At its forward end the rod 95 isprovided with the intersecting beveled and vertical faces 87 Q8, such Afaces serving forengagem'ent with a nut resting upon thewear plate 3l4 and acting, upon .Forward movement oi. the rod 95, to displace such nut from. the cha1nber 30. i
n.. bracket member 89 is serured tothe underside oiE the table l adjacent its rear edge and such bracket is provided with a threaded opening for the reception of an adjustable stop screw 90, such screw being provided with a lock nut 91, if desired. The screw 90 lies in the path of movement ot the bar 85 and .serves to limit the rearward movement oi" the same.
ot the vertical frame members and through a boss 94 projecting from such "member,
wall of the chamber 30 is pro y The lever 91 is pivoted `upon shait 93 which extends 4through one The lever 91, at its upper end, is biturcated to form spaced arms 95, 90,'which are arranged upon opposite sides of ythe bar 85 and are pivotally connected thereto by means et a pin 97. f1`he lever 91 comprises a laterally extending sleeve portion 98 'from which depends an arm. 99 having a roll 100 at its lower extremity. This roll is mounted onda pin or stud 101 and tarns freely thereon. The roll 100 arranged to enn gage within the helical slot 1.02 of the cylindrical cam 15, Ithe parts being so arranged that upon rotation of said cam the lever 91 is caused to oscillate, thereby reciprocating the bar 35 in its guideways. For preventing accidental escape of anut deiivered from the chute 27 onto the plate 31, there'may be provided a depending gate member as 103 (see Fig. 5), such gate member being pivoted at its upper edge, and being normally retained in vertical position by means ot a light spring surrounding the pivot, or by gravity, desired. Such gate member serves ter close the open, Vforward side ot the chamber 30, but is tree to swing 'forwardly to permit a nut te be discharged from the chamber 3 0 by the positive action ot the pusher rod 85.
Seleotgr.
Cooperating with the chamber 30 and with the pusher rod 35 is a selector device indicated in Figs. 1 and 6. This selector device comprises a lever 104 mounted to swing upon the pin 51 and preferably having a hub 104a upon which. the lever 50 is mounted to swing. This lever preferably comprises a casting having a longitudinally extending channel 105 which may, it desired, be closed by a plate 106 at its 'forward side. This channel is ot substantially rectangular cross section and of proper dimensions to permit a nut to slip down the same when in 'an edgewise position, but being of sufficiently restricted size to prevent tipping of the nut during its descent. rPhe upper end of the lever 104 is preferably provided with apair of anti-friction rollers 105, 106, respectively, such rollers being mounted upon studs 107 108. The rollers cooperate with a longitudinal groove 109 formed in an arcuate guide member 110, such guide member being secured by means ot bolts or in other desired. manner to a pair ot bracket arms 111, 112, respectively, which in turn are se# cured to the main `frame by means of bolts as 113, and the bolts 2G previously referred to.
Extending laterally from the lower portion of' lever 104 is a rigid arm 114, such arm being provided at its extremity with an anti-friction roller 115 carried upon a stud 116. Connected to the outer end of the bracket arm 114 is a member 117 which may be integral therewith or connected thereto by the bolt 11?, such member having an opening in which is secured the lower end of a coiled spring 113. The upper end oit the spring 113 is secured to a pin 119 liXed in the guide member 110, such spring tending to swing the lever 114 in a counterclockwise direction about its axis. The roll 115 lies in the vertical plane of the cam 23 above described, suoli cam serving by engagement with the roll 115 to swing the lever 10aL in clockwise direction in Iopposition to the action of the spring 118.
The upper portion oit the channel 105 is llaterally enlarged and is divided into two divergent chambers 120, 12,1, respectively by a centrally disposed separator member 122. This separator member, as` indicated tor example in Fig. 11, comprises a substantially fiat rear surface 123 and curved lateral surfaces 124, 125, which intersect at the edge 126.v rthis separa-tor member may be made integral with the lever 104, it desired, but is preferably formed of hardened material such as tempered steel and secured to the upper end oi `the linner wall ot the channel 105 by means yot a screw 127 or in other Jdesired manner. The chambers 120, 121 extend somewhat to the rear of the rear wall of channel 105 and are provided with downwardly inclined botto-m surfaces 123,
1.29, respectively, (Fig. .10) which lead to the vertical portion of the channel 105. T he side and front walls ot the chambers 120, 121 are preferably toi-med by a lining member 135 which may be of hardened material and furnished with guide plates such as 130, 131, respectively, where such side walls merge into the walls orl channel 105; rlhe lorward portions or' the outer walls ot the chambers 120, 121 respectively are of curved tormation as indicated at 132 and 133 respectively (Fig. 11) such walls having a curvature substantially corresponding to that of the walls 124, 125, respectively, of the separator member 122. rl`he plates 130, 131, where they merge i into such curved wallsl preferably have a similar curvature.
To the left ot the chamber 120 there is also provided al third chamber 134, such chamber being separated from the chamber 120 by the wall of the lining member The chamber 134 may also be provided with a downwardly and forwardly inclined sur- .tace 136 leading to alaterally directed channel 137 which opens downwardly at the point 133 at the side of the machine.
Upon the rear of the selector lever 104 there is secured a ratchet plate 139 (Fig. 9), said plate beingconnected to the lever by means of screws 140, and preferably being ot hardened material. This ratchet plate provides aledge 141 lying in the vertical plane of the pawl 81 and a second rear wardly disposed ledge 142 lying in the plane of the pawl 82. The rSt-llamed ledge is vot' the channel 105. The upper end of this chute, which is lined, may be beveled in opposi te directions as indicated at 147 whereby to permit. the swinging ot the member' 104 relatively thereto. The chute 146 may lead to any desired point of discharge, as. tor example to the next machine employed in the finishing of the nuts. The 'leedii'ig of nuts :from the lower end of this chute may be controlled by a suitable gate member carried by the lever 11 above referred to, it' such lever be employed.
The shaft 14 is ro-tated by means of a sprocket chain or` other suitable device engaging the wheel 16, such wheel driving the shaft through the friction-clutch arrangement described. bis the shalt` is rotated, the cams 15, 22 and 23 are simultaneously rotated therewith. lt being assumed that nuts have been dropped promiscuously into the chute 27, the lowermost ot such nuts will rest upon the plate 31. lf with the parts arranged as indicated in Fig. 1 the sha-'tt 14 is rotated in a counter-clockwise direction the cam 22 will be carried out o1' contact with the roller52, thuspermitting the lever member 50 to swing to the right under the. action or' spring 54, moving the sleeve 56 from out the chamber 30'by engagement ot the pin 72 with the side ot lever 50. fis the shaft 14 continues to rotate, the cam 23 will be brought into contact with the roller 115, whereupon the selector device will be swung` in a clockwise direction tensioning the spring 118. Such movement ot the selector lever continues until the notch 145 has been brought opposite the tooth 84 ot the pawl S2 whereupon such toot-h, under the action ot spring 7 9, drops into this notch, therebyr locking the selector device against movement in the opposite direction. lith the parts as thus positioned, the chamber 134 lies opposite the chamber 30. As the shaft 14 continues to rotate, the cam 22 comes into engagement with the roll 52, thus swinging the lever member 50 in a. counter-clockwise direction. its the lever moves in this direction, the left-hand end of the sleeve 56 moves into the chamber 30. li' at this time a nut be resting upon the plate 31, such nut will be pushed to t-he left until it is brought into Contact with the plate 32, such plate serving to stopy 'further movement of the nut by the action otsleeve 56. The lever 50, however, may continue to move to the left for a short distance, compressing the spring 61 between the sleeve and the plate 57 secured to the lever 50. As' there is normally a space between the plate 57 and the end of the sleeve 56, sufficient lost motion is proc vided between these parts to avoid any breakage due to stopping of the sleeve 56 by engagement with a nut prior to the completion of the movement ot the leve-r 50.
It the nut be eccentrically punched, or unpunched, so that its opening does not come opposite the end of the leeler bar 59, the movement of the latter to the lett with sleeve 56 will be retarded (Fig. 12). Such stopping or' the bar 59 will serve .to swing the lever 63 in a counter-clockwise ,direction about its pivot 64, thus tensioning the spring 69 and carrying the contact member 67 away from vthe end of rod 73. As the rod 73 is thus unaffected by the swinging of the lever 50 to the lett the pawl 82 remains in engagement with the tooth 145 of the selector lever. As the cam 22 now moves away trom the roll, the lever 50 is swung to the right by means ot' the spring` 54 and substantially at the same time the groove 102 in the cam 15 acting upon the roller 100 moves the pusher rod 85 forwardly. The pusher rod 'engages the detective nut resting upon the is discharged from the machine at the point 138. lt will thus be seen that defective nuts are automatically discharged through the passage 137 and are not delivered to the succeeding machine.
lt the lowermost nut which rests on lplate 31 is substantially perfect, the end of the teeler bar 59 passes into the opening in the nut as the sleeve 56 moves into the chamber 30. Under such circumstances the spring 09 retains the lever 63 substantially in vertical position with the stop screw 66 engaging the plate 57. is the lever 50 completes its movement to the lett the contact member 67 engages the end of the rod 73 and causes it to slide to the lett. the lett, its lett-hand extremity, which engages the lug 74., swings the lever, comprising the arm 75, in a counter-clockwise direction, vthus tensioning spring` 79 and at the same time lifting the pawl 82 whereby to release its tooth 84 'from the notch 145. The spring 118 immediately swings the selector lever 104 in a counter-clockwise direction until the tooth ot the pawl S1 drops into the notch 144 holding the selector in such position that the chamber 121 lies opposite the chamber 30. Assuming that the bottom nut N drops upon the plate 31, with the flat tace 150 of the nut to the left and with .as this rod moves to the chamferedface 151 thereofin position for engagement by vthe left-hand eno of the pluneer sleeve 56:(Fig. 11) the latter, upon vmovement to the left, will press the flat surface 150 of the nut firmly against the plate. As the diameter of the, nut is, however, slightly greater than that of the cavity 32, thernut is not permitted to enter the latter, and thus fails to make operativel contact with the end of the plunger 36. The tooth 83 of the pawl 81,. which now engages the notch 144, thus continues to retain the selector device in such position that the chamber' 1,20 lies opposite the chamber 30. As the driving shaft 14 revolves and the member 85 is moved forwardly, the nut positioned within the chamber 30 is thrust forwardly into :the chamber 121 raising,r the gate 103, ifvsuch be employed, it being understood that the pusher sleeve 56 is retracted priorto the forward motion of the bar 85. As the nut passes into the chamber 120, it rests upon the inclined surface 128 and tends to slide downwardly thereon. As the nut moves downwardly` it encounters the surfaces 132 yand 124, and is thus caused successively to assume thebroken line positions indicated at N. N2, 11. When the nut reaches the latter position it is free to fall. vertically through the channel 105 and into the upper end of the chute .146, it being; noted that as the nut passes down such channel its fiatsurface is presented in a forward direction.
lf the bottom nut in the chute drops upon the plate 31 with its charnfered side to the left,-that is to say7 in a position such that it may be received within the cavity 30 with its flat surface 150 in position for engagen'ient by the end of sleeve 56 10i.y the movement of the latter serves to thrust the chanifered end of the nut into the cavity .534. fis the end of the plunger 3G is of a dianieter somewhat greater than the opernngv in the nut, such plunger is pushed.outwardly as the nut enters the cavity 34. This movement of the plunger aetuates the lever il? and the bell crank, comprising the arm and terres to tension the spring` 47 and to li 't tthe pawl tooth 83 from the notch 144. T he spring' 118 immediately swings the lever 104 vto 'the left until the tooth 83 engages the notch 143. lith the parts in this position the chamber 121 of the selector device is opposite Athe chamber 30. Upon retraction of the sleeve 5G and projection of the rod the nut is pushed out fromthc chamber 30, raising the gate member 103, if such be employed.y and passing` into the chamber 121. As the nut enters the latter chamber it slides down the inclined surface 129 and in so doin encounters the surfaces 133 and 125. respctively. The nut is thus caused to assume the 'position indicated in broken lines N", Nt. Fig'. 10.y and from the latter position drops vertically through the channel 105.
rllhe nut thus delivered from the chamber 120, enters 'the channel 105 in a position similar to that of a nut delivered from the chamber 121, and thus regardless of the position of the nut as it falls upon the plate 31, it is delivered through the chute with its fiat face always directed forwardly. The machine thus serves in an automatic manner not only Vto eject improperly formed nuts, but also to orient all perfect nuts passing down the supply chute in such manner as to cause them 4to occupy similarl positions in the delivery chute. I I
It will be evident from inspection of Figs. l0, 11 that the upper end of the channel 105 is entirely open, and thus may be inspected without the necessity for removing4 parts or dismantling the machine. This is of especial advantage in a machine of this character as it permits the ready removal of nuts which may, for one or another reason, become jammed in the delivery channel. The machine may be operated with great rapidity and may be so co-ordinated with preceding or successive machines as to provide a continuous supply of properly positioned nuts .forsubsequent operations. y
While the vai'iouselements of the machine have been described with reference to the specific shape and arrangement of parts herein illustrated. it is to be understood that various changes in form or arrangement. as well as in location of the various parts might vwell be made without departing from the spirit of the present invention.
