'[0 all whom it may concern:

Be it known that I, CHRISTIAN F. HEIN- KEL, a citizen of the United States, and resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Conveyers, of which the following is a specification.

My invention relates to conveyers which have track wheels adapted torun on rails and connected by said chain links.

The object of my invention i a simple, durable, and eflicient conveyer.

I attain this object by the mechanism illustrated in the one perspective view on the accompaning drawing.

Heretofore it has been customary, on conveyers, to employ comparatively wide rollers running on a track of some kind and carrying the load. It has been found that such structure is not as efficient as it might be and that the rollers frequently stick and either prevent the operation of the conveyer as a whole or increase the already high friction of the parts.

The present invention aims to eliminate these disadvantages by using separate track wheels and connect them by shafts so that the rolling radius of the wheels is greater than the resistance radius of the shafts. .With such an arrangement, the wheels roll along the track easily and do not stick under ordinary circumstances and the friction of the chain is reduced to a considerable extent.

The conveyer illustrated in the accompanying drawing is of the floor type and may be so sunk into the ground that the top of the rail are level with the floor.

Referring now particularly to the drawm The lower track rails 10 are mounted on the walls of the pit 11 and are interrupted as shown to provide the spaces 12 between them.

The cross rails 13 are also mounted on the walls of the pit 11 and carry the upper track rails 14 substantially in alignment with the rails 10.

The bearing blocks 15 are also mounted on the walls of the pit 11.

The shafts 16 are journaled in the bearing blocks 15 and the sprockets 17 are secured to these hafts substantially in alignment with the rails 14.

The conveyer chain is composed of the track wheels 18, the shafts 19, and the links 20. I

Each shaft 19 is journaled in a pair of the wheels 18 and each pair of the shaft 19 is connected by a pair of links alternately on the inside and on the outside of the wheels. The whole chain structure may be held together by cotter pins or other means well known in the art.

The track wheels 18 travel on the rails 14 and also on the rails 10 and are guided from one rail to the other by the sprockets 17, the teeth of which engage the track wheels directly, so that the chain is propelled by the sprockets in either direction as occasioned by the rotation thereof due to the power applied by the belt 23 and the pulley 24 secured to one of the shafts 16.

The flanges 22 on the wheels 18 prevent the same from running off of either the rails 14 and 10 or the sprockets 17.

The spaces 12 are provided for the purpose of permitting the chain to'sag down and thereby take up the slack thereof.

When the chain so sags down into the space 12, between the interrupted rails 10,

the slack thereof is taken up at a point where it will not interfere with the proper operation of the conveyer. If this space 12 is not provided and the lower rail or track is made continuous, the chain will sag at the sprockets and the stretch thereof will, in time, be suflicient to permit the chain to run off of the sprockets unless an adjusting means is provided. In the present invention, no such adjusting means is needed, the chain is always provided with sufiicient ten sion for proper operation, and requires no attention; and furthermore, this tension is always uniform, is governed by the number and weight of those links which span the space 12, is provided automatically by the weight of these links as they pass over this space, and requires no attention.

In the conveyor shown, no provision is made for carrying a load. Such load may be placed directly on the shafts 19 since they need not rotate; or such load may be carried by the links 20; or special contrivances may be attached to the load to engage either the shafts 19 or the links 20 or the wheels 18. The nature of the load to be carried by the conveyer should determine the best method of providing means for carrying any particular kind of a load.

It will be notedthat the vl0 1d iscarrie d by the comparatively si all shatts le ph gfiphe comparatively large track wheels 20 are j ournaled on the shafts 1 9 that the sprocke ts 17"engage the track heels directly; l fd that all similar parts areduplicates; 'Such an arrangement provides economy of manufacture, simplicity, durability, and high er? ficiency.

I claim 1. A conveyer comprising, a pair of up per track rails and a pair of lower track rails, track Wheels arranged in pairs adapted to run on said track rails, aplu'rality of shafts extending'across both of said-pairs of track rails, each of saidpairs oftrack Wheels journaled on the, ends of one-of said shafts, and each of said;shaftsconnected to the next of said shafts by one pair of links.

of these pairs of Wheels journaleclon a shaft and each pair of these shafts connected by links placed alternately on the'outside and on the insideof'these track Wheels, sprock ets engaging said'wheels, and meansfor rotating sald sprockets,

3. A conveyer comprising, upper andloWer tracks, anendless chain composed; of

pairs of track wheels and-each ofthesepairs ofwheelsvjournaled on a shaft each pair of these shafts connectedby links" placed alternately on the outside and on the inside of a Wheel P OQlSQtS at ter nd a rl ibks. and i t fmed at. heres and the teethofth's sprockets en ag n said track Wheels, and means for rotating-said sprockets.

4;. conyeyer comprising, upper and lower tracks, an endless chain composed of pairs of track Wheels and each of these'pairs of Wheels journaledi on a shaft and each pair of these shafts-connected by links placedalternately on-the outside and on the inside of these wheels, sprockets at the outer ends of: said-tracks and intermediate thereof and the teeth of these sprockets engaging these Wheels to operatesaid chain and guide the same from one of said tracks to the other, andin'eans rotating said sprockets.

5; Ajconyeyer including, a' chain and rollers therefor, an upper track for said rollers, and alower track for said rollers interrupted ,to provide a gap or space therein to permit said chain to'sag and thereby take up the slack, thereof;

6. An endless conveyer chain having pairs of track heels and each pair mounted on a shaft, andiveach pair of said shafts connected by links placed, alternately on the outside and-onethe inside of said Wheels.
