Serial No. 334,702.
This invention relates to a new and improved clearance mechanism of the type associated with a chute or the like for clearing misaligned blanks thereon.
It is the object of this invention, among other things, to'provide a positively actuated mechanism of this character that will clear all misaligned blanks and follow the path of the parts that receive the blanks for a portion Figure 1 is a side view of'my improved clearance mechanism and so much of the adjacent parts as are essential to atull understanding thereof;

"Figure 5 is a sectional view thereof taken generallyupon line 55 of Figure 3; and

In the embodiment of my invention as shown herein, 10 indicates a portion ofthe hopper, into which blanks or articles areassembled in an indiscriminate mass, and from which, by suitable mechanism, they are taken and placed onto a chute mechanism This latter mechanism, as shown, comprises companion plates 11 and 12 that are arranged with an open space therebetween, into which project the shanks of the blanks 13 and the heads rest upon the top ofthepl'ates, substantially as shown in' Figl rel Thespace "for the heads is limited by the cover plate 14:
that is secured in any of its adjusted positions in a manner well known to the art.
chute.
Associated with the hopper isa fixed lug 15 that'supports the bolt 17, and upon which is the wheelbracket 16. As the bolt 17 passes through the slot 18 in the wheel bracket, provision is thus made for varying the relative positionof the bracket.
Fixed in'the wheel bracket is the shaft 19, upon which is rotatably mounted the sheave wheel 20 that is driven by a belt 21. Secured on the hub of the sheave wheel20 is a clearance wheel 22, in each side of which is arecess containing a clearance finger 24, havmg rounded ends 25. The slots 26 in these fingers are provided so as to permit the fingers to straddle the hub of the wheel 20. Each clearance finger 24 is held against lateral movement within its recess by a cap 27 that is fixed to the side of the clearance wheel 'with its outer face substantially flush with j the side of saidvwheel.
' A friction plate 28 engages the inside face of each clearance finger under pressure of thespring 29, which pressure is sutficient to prevent the clearance fingers from moving under centrifugal force.
Secured to the wheel bracket 16 are the l companion cams 30 which are spaced apart by the block 31 and the like so that there is a cam in the path of each clearance finger.
These cams are, shaped so that as the clearance positively moved within the clearance wheel and the opposite. end 25 approaches the top of the chute plates and is maintained in contacttherewith until it has passed thereby, during which time any misaligned blank is struck by the finger with sutficient forceto knock it away from the clearance wheel. It then either falls back into the hopper for representation to the chute or slides along the top ofthe chute plate or plates, andmay, and in most cases does, fall into proper alignment with the other blanks and pass down the r The ca1n30 causes' the end'of the finger oppositefthe cam to move outwardly after it has passed over the chute plate and into a tation.
tion of the path of the end of each of the fin ers is indicated by the broken line 32.
K screw 33 in the wheel bracket which impinges against the hopper or other adjacent mechanism forms an adjustable limiting stop for the bracket and the screw 3 in the poppet 35 provides for an adjustment of the bracket and through it the position of the clearance wheel toward and away from the. chute plates and also prevents the same from being forced outwardly from such position.
A stripper plate 36 is fixed to th e bl ock 31 and provided with slots 37, through which the clearance fingers 24 pass during their re-- As these slots are only sufficiently wide to permit the fingers to pass therethrough any article or blank that 'mightbe caught in the fingers is stripped therefrom and prevented from passing thereby. This plate also prevents a blank from passing over the clearance wheel if it should be thrown thereagainst by the action of some part in or about the hopper. v
One face of each finger is cut away at 38 so as to provide means to accommodate blanks with heads of various widths or diameters. The fingers are positioned in the clearance wheel so that thecut-away portions 38 are toward or away from each other as may be desired. When toward each other, as shown in Figure 5, a blank with a larger head can pass therebetween than if the same are reversed. Thus, by merely reversingthe position of the fingers, the clearance wheel will accommodate blanks with heads of various diameters and sizes.
Aside from the suggestions herein contained as to modifications of my improved mechanism others will readily suggest themselves to those versed in the art, and therefore, I do not limit myself to the'exaet construction herein shown and described, but claim all that falls fairly within the spirit of the appended claims.
