The screen is 'vf Figs. 5 andf6 are a si'del elevation partlylinv 'preferably provided witlisuitable side pieces i 'section and a'plan' view, respectiv of an '52 to guide the material upon itin its travelv material below a certain predetermined size to fall throughthe screen so that it will not' to the crusher. These side pieces and `screen together form a chute with a foramlnated bottom. Apertures 54111 the screen permit be delivered to the crusher. This material -falls into an vapron 56 terminating at 58 past the discharge point 61 o f the crusher.

For oscillating screen 18,- I mount -a ,itf

tingen bracket 26 forsupporting a shaft 60 -onwhich the end clips 62 of pitmen 64 are journaled; .Similar clips engage pintles 66 carried by the screen intermediate its ends.

It will bexapparent that a rather rapid oscillatory motion will be imparted vto screen 18 when the Crusher speed.

is operating at its normal Referring now to Figures 2 and 4, rails 'A 68 underlie the edges of screen 18, and

each rail-carries short tracks 70 pivoted "theretoas atl 72'near each end thereof. Suitable brackets 74, one fastened to crusher 12-` and. another to one of the u'prights 48, carrywheels 76 engaging tracks 70 to support the screen and a ron. I have provided suit- 'able adjustment means for tracks 70 inI the nature of sliding wedges 78 interposed between tracks 'Z0 and rails 68, and adjustable by means of adjusting screws 80 and nuts ditions of material.

Under certain conditions, depending materia the crusher.

apparent that b setting'the tracks at -oppo-;

site ends at'di' erent angles, :a`slight movement of rotation could also be employed if sufficient for certain classes of work, and

operates .as follows :'-T11e operator stands -on-screen 18, and throws to one side pieces of material too large to pass between bars 46. -By means ofgale 50 he controls the owfrom the hopper to the screen, to deliver material to the crusher as fast as the `crusher can handle it. The material fallingthrough 'the -screen travels down apron 56, and is joinedkbefore leaving` the apron by falling from thev discharge 61 of In this .way the lower end of apron 58 delivers' the finished aggregate chiefly on the nature'of the'material handled, and the exa'ctness with whichv the maximum size of particle inthe finished aggregate must behmited, it is `desirable the Crusher to deliver particles of maximum size considerably in excess of the diameter of holes '54, so that a fractionfof the dis-- charge from the' crusher lwill always be returned to the crusher 4for -,a second passbefore it is reduced to a size that will pass screen 18.

This vaccomplishes .two results.

First, screen 18 is A the element determining the -size of particle delivered, rather than the crusher, and the maximum size lcan be determined in this way with considerably greater accuracy. Second, the crusher can be set with a slightly Wider discharge aperture, and .vill handle more material with such an adjustment.

The structure I have illustrated for returning the crusher. discharge to the scrcenf comprises "a laterally vdirected chiite 86 eceiving the discharge from the crusher and -delivcringit to a suitable conveyor 88,

.which conveyor .elevates the material and drops' it on chute 90, from which it falls" back on screen 18.

Conveyor'88J may befrendered operative or inoperative, simply "by removing' or re placing chute 86.' Whether it is employed or not, the discharge fromv apron 58 will be the finished aggregate ready for use. a I prefer to employ aVl readily vportable storage receptacle 92, see Figure 1, forre- .ceiving this aggregate, whenever it is necessary to store a certain amount of the aggregate for periodical delivery to wheel barrows, wagons, motor trucks," etc. This bin may be of the ty e described in my copendin'g application, filed July 8th, 1922.

Any Suitable conveying elevator may be erial Number 573,710,

I have illustrated a conveyor 94 driven by belt 96 from the conveyor as well as the crusher. 88 may, ifdesired, also be driven from the other end of the Crusher shaft, and is illustrated as provided with a drive ypulley 100 vforthat purpose. Conveyor 94 may obviously be mountedlon suitable s'caiiolding or standards. It may, if desired, have its lower-end supported on brackets 102.rfe'movaloly.'l
