3 on the cam shaft, a cam'4 on the drum, a stub shaft 5 journaled in brackets upon the frame 1, a bell crank lever 6 pivoted upon the stub shaft 5, a roller '7 carried by the lever 6 and engaging the cam 4, a coil spring 8 terminally-secured to said lever 6 and frame 1, a bracketQ secured upon the frame, a stub shaft lfljournaled inthe bracket 9, an arm 11 swingingly mounted-on the stub shaft 10, a rod 12 terminally connected tozthe'.

. chute 'of feeder mechanism such as that illuse' trated in my application, Serial No. 567,106, filed October 5, 1931; tothe lower end.of a:slide. 16

and are adapted to bemoved automatically up the slide by'mechanism operable by the leveri6' 'into a chute 1'7 from which they are adapted to and away from the jawsz13i 22 on the frame 1 and tea bracket 23 pivotally connected'to a lever24 on the stub shaft 5, while the section '19 comprises an angle iron and'is carriedby and movable both transversely and longitudinally of the strip 20'0f the section 18. Bolts25 engaging transversely extending slots 26 in the strip 20. and longitudinally extending slots 27in the angle section 19 and engaged by nuts 28-are used to hold the section 18 in adjusted position.- The angle. iron 21 extends the full length of the strip 20 and is provided at its lower end with a lateral flange 28 that is adapted to cooperate with thelower end 29 of'a delivery chute 30, such as C of the feeder mechanism in my application, Serial No. 567,106,-to guide the servesto retain and keep the work from buckling in the slide. As shown, the plunger 31 is movable between and longitudinally of the

strips

20 and 32 andiscarried by the lateral flange 33 of a bar 34 slidably mounted in the bracket 23 and actuable by an arm 35 carried by the lever- 24; The strip 32 is carried by the lower ends of bolts 36 adjustable vertically in the bases 37 of inverted L'-shaped brackets 38 fixed to the bases of the angle bars 19.

Nuts

39 and 40 respective- 8 1y threadedly engage thebolts 36 above and below'the bases 37 and serve to retain the bolts 36 and "strip 32 in adjusted position. 41 is a latch member or detent pivoted in a bracket 42 secured t6 the angle 21 and movable through an opening 43 in'saidiron for preventing the bush ings *15 once they have passed upwardly beyond the latch" from moving backwards below the same; 44is' a bolt "projecting rearwardly from the latch inteimediateits ends and extending through a socketi45 and opening 46 in the bracket 42; 47' is'a nut 'threadedly engaging the bolt-44 upon the outer side of-thebracket 42; and 48 is 'a coil spring sleeved upon the bolt 44 within the socket 45 and normally maintaining the free end of the latch inwardly'within the channel of the slide- 16. 1 o Q d The chute 17 atjthe'upper end of the slide 16 is 'also channel-shape and preferably comprises two sections'50 and 51 respectively. The section 50 consistsof a-flat metal strip 52 and an angleiron 53 and is fixed to a bracket 54 pivoted at; 55 upon the bracket 22, while-the section 51' comprises an angle iron and is carried by and movable both-transversely and longitudinallyfof the 20 chute 1'7. 7

In order that the movement of theplunger 31:

strip 52. Bolts 56 engage transversely extending slots 5'7 in the strip 52 and longitudinally extending slots 58 in the angle section 51 and are engaged by nuts 59 for holding the section 51 5 in adjusted position. The angle section 51 terminates short ofv the lower end of .the strip 52 and cooperates with an upstanding flange 60 of an L-shaped bracket 61 secured bysorews 62 to the bracket 54 to define a lateral opening 63 through 1 which the bushings '15 may be discharged one at i a time by the plunger 14. Preferably the side flange 64 of the angle iron'53'projects'upwardly beyond the upper end of the strip 52 and cooperates with the flange 65 .of the angle iron 21 to 1 5 guide the bushings from the slide 16. into the chute 1'7. 66 is a bolt or set screw threadedly en- 7 gaging a depending arm 6'7 of the bracket 54 and abutting the rear face 68 of'the bracket '22-for controlling the elevationof the lower end ofthe will be in timed relationtothe movement of the jaws 13 and 13 Ihaveprovided an adjustable connection between'the levers 6 and 24 respec- '5 tively. As shown, '70 is an 'L.shapedplate rigid with the lever6 and having thezbase T71 of the vL received within a bifurcated portion .72 of the lever 24., and 73 and 'l'respectively are set screws or bolts threadedly engaging the furcations 75,

, 301? and '76 respectively and engaging oppositesides of the base'll of the L-shaped plate. j: r

.In use bushings 15 discharged into the slide 16, for instance, from achute such as of a feeder mechanism corresponding to thatillustrated in 36 my application, Serial No. 567,106, willbe pushed one at a time by the plunger 31 upwardly the slide 16 past the latch .41. Successive bushings will push those ahead so that they will move one ata time fromthe upper end of the slide lfi into the chute 17. "IThe plunger -1e:will--remove the bushings from the lower end of the chute, l'linto the jaws- 13 and 13 which in turn will carry or transfer the bushings to the arbors (not shown) of the machine. Adjustment of the screws 1'73 453 and 74 will control the movementiof the lever 24 and plunger 31 relative to the lever 6 and jaws- 12 and 13, while adjustment of the bolt 66 relative to the depending portion 67 of the bracket 54 will regulate the position of the chute 17 relative,- 503 to the plunger 14. Theadjustmentof thenuts 39 and 40 regulates theheight of the strip 32;

above the strip 20 of the slid e,.while the adjust-J ment of the nutfl'lon the bolt 44 regulates the? 5 position oi the latchielrelative to the angle iron, 5 '3 21.

Since the plunger 31 is secured by screws 80 to the flange 33 ofthe slidablebar-Bd it will be apparent that plungersof various sizesemay' be; used according to the diameter of thebushings to be received within the slide16. Furthermore,

?? adjustment of thebolts 25 inthe slots 26and27.

and of the bolts 56 in the

slots

57 and 58 can be made to-take care of the bushings of various sizes. For example, the bolts 25 may be adjusted in the longitudinally extending slots 27-.according to the diameter of the bushings to bereceived betw'een the lateral flange 28 and the plungeriilgwhilethe bolts 25 may be adjusted in the slots26according to the length .ofrthe bushingsto travel longitudinally of the slide. Likewise adjustment; 1010f the bolts 56 in the l-longitudinallyextending:

slots-58 may'be made according'to the diameter of. the bushings to be discharged from between-:1

the flange-60 and angle iron- 53 and adjustment, v of the bolts 56 in the slots 57may be made accord-.

Ii ing to-the length of the bushings to travel lon i tudinally of the chute. In addition, the screws 62 engaging the longitudinally extending slots 81 in the L-shaped member 61 enable the latter to I be adjusted relative to the lower end ofthe chute 17' if desired.

Thus from the foregoing it will be apparent that I have provided arr-extremely efiicient and practical means for' feeding the work to the machine. The assembly is simple in construction, can be manufactured at a comparatively low cost and can be easily installed. Moreover the work is conducted automatically from the chute 30 to the jaws 12and 13so that the assembly requires practically no att entionrafter the desired adjustments aforesaid havebeen made.
