SPECIFICATION forming part of Letters Patent N o. 719,178, dated January 27, 1'903.

Application filed J'uly 1'7, 1902.

lo LZZ wit/)mf it. may concern,.-

Be it known that I, RICHARD BLUM, a su bject of the Emperor' of Germany, and a resident -of Berlin, Germany, have invented a new and Improved Conveyer, of which the followin'g is a full, clear, and exact description.

The invention relates to conveyors for moving coke and other lumpy material along in a trough or a channel from one place to another; and its object is to provide a new and Iimproved conveyer which is simple and durable in construction, very eective in operation, and arranged toinsnre proper cooling of the material while moving the same bodily without bringingit in contact with the channel-walls and ,without danger of crushing or pulverizing-the material. y

The invention consists l.of novel features and parts and combinations of the same, as will be more fully described hereinafter andthen pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings,

responding parts in all the views.

Figure l is a longitudinal sectional eleva- Fig. 2 is a trails- Verse section of the samevon the line 2 2 of, Fig. l. Fig. 3 is a'plan view of the same with the protecting-coversfor the wheels re-4 moved. Fig. 4 is an enlarged transverse sec- 'tion of part of the improvement.- Fig. 5 is a The improved conveyor is provided with a' trough or channel A, preferably made U shape in cross-section and supportingonits sides above the bottom` of the channel longitudinally-extending track-rails B., n which are, mounted to travel wheels C, of which two opposite wheels are secured on the ends of a transversely-extending shaft D. The several shafts'D are spaced suitable distances apart, and on each of theshafts is fitted a sleeve E, on which are mounted spacers or washers F, each having one end formed with a reduced portion for engaging an eye G' in alongitudinally-extending link G, provided on its other end `with a similar eye G', engaging a vcorresponding Washer F on the sleeve Serial No. 115,938. (No model.)

E of the next following shaft D, as will be readily understood by reference to the drawings. The several links G are spaced apart short distances, so as'to form a grate, bodily movable through `the channel a-nd adapted to carry on its upper surface the materialto be conveyed from one place to another. yEach upwardly-extending arm Gz'tofsu'pport the material at the time the movable grate moves L,up an incline to, prevent the material from sliding down the grate...

The links G in some of the transverse rows are provided 'at the end opposite the arm G2 with depending arms G3, reaching within a short distance of the bottom of vthe channel A, so that any material that falls between the links G down into the'bottom of the channel is carried along by the arms G:l when the grate is in motion.

It is understood that the grate consists of the links, the shafts, and the wheels traveling on the track-rails B, is made in endless` shape, and is set in motion by any of the lwell-known methods, such as sprocket-Wheels and ther'like, and the material is discharged onto the links at one end of the cha'nnel'and is then subjected to sprays of water for cooling the material, the 'water standing lin the channel. to assist in reducing the temperature of the material while the same is carried'forvv'ard in the channel.

In order to protect thewheels C and trackrails B from the material, I provide links H adjacent to the wheels C, the links H being extended upwardly to prevent thematerial sliding from the grate tothe wheels and trackrails B. The links H connect adjacent shafts D with each other, and in order to prevent the material from falling onto `the Wheels and track from the top of the channel I provide ing covers I, preferably made of sheet metal, and secured to tho inner faces of the sides of the channel, as plainly indicated in Fig. 2. The covers I extend down wardly and inwardly over the top edges of the side links H, vso as to preventmaterialfrom passing to the trackwheels C and-rails B.

Now by the arrangement described the links G do not come in contact with the walls of the links G is provided at one end with anv the sides thereof with long'itndinally-extend IOO 'of the channel A, and consequently the side l links move bod-ily throughthe channel without touching the same, so that resistance to the fo rward movement of the grate by friction is greatly reduced and comparatively little power is required.` .to impart atraveling mo-v tion to the-grate. By having the links-spaced apart the' Water forcooling the coke can readily p ercolate through the material and pass betweenl the links into the channel to accumulate therein. j

Having thus described my invention, I

claim'as new and desire to secure by Letters Patent- 1. A conveyer comprising a track, wheels mounted to travel on the track, transverse shafts carrying the Wheels and spacedl apart, and links connecting adjacent shafts with each other and spaced apart transversely, to form a grate for carrying-inaterial, the grate being movable lengthwise in a channel above the bottom.v thereof,'as set forth.

' 2. `A conveyer comprising a track, wheelsy mounted to travel on the track, transverse shafts carrying the wheels andn spaced apart, and links connecting adjacent shaftsiwith each other and spaced apart transversely, to form a grate for carrying material, the grate being movable lengthwise in a channel above the bottom thereof, the` said linksbeing provided at one end with `upwardly-extending retaining-arms, and' sundry of the links being provided with downwardly-extending arms, reaching close to thebottomk of thel channel, as set forth.

4:. A conveyer comprising a channel provided with a track, Wheels mounted to travel on the track in pairs, transverse shafts, each carrying on lits ends a pair of the wheels, links connecting adjacent yshafts withveach other, the links being spaced apart to form a grate for carrying material, the grate being movable lengthwise in the channel, above the bottom thereof,and means for protecting the wheels from the material, consisting of protecting side `linksom the shafts and covers fixed to the casing at the sides thereof and extending downwardly7 and inwardly over vthe top edges of the said side links, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

RICHARD BLUM.
