To all whom t may concern:

Be it known that I, WILLIAM E. PHILIPS, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Pivoted Bucket Conveyers, of which the following is a full, clear, and exact description, reference being had to thev accompanying drawings.

This invention relates to conveyers and particularly to conveyers of the type wherein dumping buckets are employed.

One of the objects of the invention is to provide in a bucket conveyer, a simple form of bucket and an eflicient means for dumping it.

A further object ofthe invention is to provide in a conveyer a bucket which is adapted to turn completely over with a continuous motion to dump its contents.

An additional object of the invention is to provide in combination a bucket, means to gradually invert the bucket, without undue shock or jar and then return it to normal position.

Another object of the invention is to provide in combination with a dumping bucket,

conveyer means to cause the buckets to dump their contents at spaced points along the trackway. f

Still another object of the invention is to provide an elficient trip carriage for dumping the bucket of the conveyer, together with effective means for moving thisl carriage.

Further objects of the invention will be apparent yfrom the following description taken in connection with the'accompanying drawings, wherein Fig. 1 is an elevation of a portion of a conveyer constructed according to my invention; Fig. 2`is al transverse vertical section of the same; Fig. `3 is a top plan view of the portions of `the conveyer shown in Fig. 1; Fig. l `is a sectional elevation of a trip carriage lookingv from the interior outwardly; Fig. 5 is a longitudinal sectional elevation of a pair of adjacent conveyer rollers and associated part; Fig. 6 is a sectional plan of the same; Fig. 7 is an elevation of a conveyer structure; Fig. 8 is a top plan View partly in section, showing,

the means for reversing the travel of the trip carriage, and Fig. 9 is an elevation of the clutch and sheave.

Referring to the drawings by reference characters', I have shown at 5 a conveyer comprising a series of connected members passing over suitable sprockets 6, mounted in standards 7,A a portion of a conveyer is shown in detail in Fig. 1, wherein 10 is a suitable `supporting bracket having a base portion 11, a transverse lower member 12, and spaced upper flanges 14. I haveshown suitable tracks, as Trails 15, secured to the cross member 12, while upon the upper portion la, I may provide suitable rails 18. These rails may be secured to the brackets in any suitable manner, as by clamps 19.

The conveyer `mechanism is' adaptedA to move on wheels 2O shown as running 'on` the rails 13. These 'wheels are shown as mounted on suitable vaxles 21. Upon the axles I may secure links 23 joined toform a belt-like structure. The links 23 may be se-y cured in place by suitable means such as cotterpins 24. f i ,y

vThe conveyer 23 is A adapted to have buckets as shown@ at A mounted thereon. These buckets may allA be of similar construction comprising curved bottom and ,side portions 3G and the endvportions 27,

shown as substantiallyflat. I have indicated reinforcing members at 28 which may befcastings secured by riveting or lbolting, or any other suitable manner upon the ends of thef buckets. Each reinforcement is shown `asprovided with a boss 30 through which the axle 31, upon which the bucket rotates, extends.

The axle 31 is continued through bothy sides of the links 23, as at 31a. A suitable spacing member 31h through which the axle l extends has bosses 31C fitting notches in the links 23 to prevent rotation'thereof. Lateral movement is prevented by the stud 31d. The reinforcement 28 yis also shown as provided with a pair of upper bosses 32 and 33, and a lower` boss 34:; Theupper bosses are of less lengththan the lower boss, and through these upper bosses shafts 35 extend. Upon these shafts I mount suitable antifriction rollers 37. The shaft 35 `may include a fastening. means, such as the nut 38, and may have a collar at its outer end to secure the roller in place while the inner end may be stepped, as at 39, to provide a shoulder to bear upon the boss so that the surface is designated 54. The outer cam surface is shown in F ig. 1, as comprising upwardly inclined portions which merge into the straight portion 56. v The inner cam comprises the upwardly inclined end portions 57 connected tothestraight portion 56. Abovethe inclined portions 57, I have indicated approximately triangularly shaped cam portions 58` 'lhe two portions 57 and 58 between them provide in effect a groove 59 for a purpose-to be presently described. v

The action of the trip carriage on thedumping bucketsl will now be described for convenience, we willv assume that the trip carriage is stationary, the belt is moving to` the left in Fig. 1 andy that the bucket A,

is just-in the act of being dumped. The lower roller 40 on this bucket Ar. strikes theA outer cam and begins to run up the inclined portion of the same asy the bucket is advanced along the rail. straight portion 5'6 of therail, its top approaches the vertical as it turns about the pivot 30. As its bottom roller 40.moves on to the straight portion of the raiL-the roller on the boss 33 strikesthe inclined portion 57 ofthe inner cam andas the bucket advances this roller moves between the cams 57 and 58, consequently Aitsmovement is upwardv move through the groove 59 betweenthe cams 57 and 58` at the left as shown in. F ig.

1. As soon as this forward roller leaves the groove 59, the roller 34 comes in contact with the outer cam surface 55 andsmoves down the incline to gradually right the bucket.

It willl be; apparent that the operation of turning the bucketl over will. be done without; any: jar or shock. detrimental to the operating parts of thestructure. It is exceedingly simple, while positive in operation..

lnstead of having the buckets dump in one place it is frequently desired to cause them to dump in order over an extended length. In order to provide such a dumping action, I have shown.` a device in Figs. 7, 8 and 9 wherein the trip carriage 50 is connected at eachpend with: cables 83, shown as wound on sheaves` and 86 mounted on, shafts87, and 88. The sheaves are free to rotate on the shafts` and in order to drive As the bucket nears: the

them I provide suitable means comprising Clutch members 89 and 90. These clutches comprise the usual tootheddiscs 94 and 95,

levers 96V and 97 and opera-ting members 98 and 99 on the lever. The action is such that the movement of each operating member 98 andv 99 back and' forth causes the clutches to be thrown in and out.

The cables 83 secured to the trip carriage 50 and wound upon the sheaves 85, carry suitable sto-p members 100. These stops may include suitable springs 105, and may be made adjustable lengthwise of the cables 83 by the adjustable mea-ns 106, shown as a slidingcollar.

To prevent undue shock, the cables 83v are secured toeaclr end of the trip carriageby suitable spring connections 110.r These connections may comprise the rod 11.1 having ay spring 112 thereon, bearing at one end against the trip carriage and at the other end against a suitable stop or abutment 114 on thevrods 111,

It is tov be noted that the stop members- 100 are secured on the cables-near the point of attachment of the cable to the trip carriage 50. Near the other end of the cables.

I may provide suitable stop members 120, here shown as tubular members surrounding the cable and secured; thereto. These stop members 100 and 120 are adapted to operate on opposite sides of the operating member 98. The stop member 100 serving to. throw out the clutch connected with an operating handle while the member 120 throws in the clutch. The member 120may be of elasticl or resilient material such asa.

rubber hose or tube. The operation of the device will be described,.,' The trip carriage 50 is shown as moving toward the left in lFig, 5. A further movement will cause the stop 100 to strikethe operating member 98 and thus throw out the clutch. 89.l At the same time the bumper 120 on the other cable strikes' the other operating member 99 and` throws in the clutch 95. This causes the cable to move in a reverse direction and to wind uponthe sheave 87 while unwinding from the sheave 85. The movement of t-he trip carriage, it willl thus be seen, is alternately back and forth. -The conveyer buckets move in one direction and since the trip carriage has reverse movement first with and then opposite.- to the movement of the conveyer buckets', it follows that in order to obtain definite spaced pointsk of dumping the diameter of the sheaves-.of the two pulleys must differ, Consequently the sheave 85 is shown as; of greater diameter than thek sheave 87.

It will be apparentA that I have described a de-vicewhereby the buckets may be dumped 1nl order` over an extended space, and inV which the operatingr means; works automati` cally.

It will, of course, be understood that, if desired, the trip carriage 50 can be arranged to dump repeatedly at the same place.

Having thus described my invention, I claim:

1. A trip carriage for endless conveyers comprising in combination, two connected frame members, and Wheels supporting said members, each of said members having an inner and an outer trackvvay.

2. In combination, an endless chain comprising a plurality of pivoted buckets, rollers carried by each bucket, a trip carriage disposed beneath the conveyer, said carriage having outer cam surfaces and inner cam surfaces providing trackvvays for the rollers, the inner trackways being disposed in a vertical plane different from that in which the outer trackways are disposed.

3. In an endless bucket conveyer, supports, sprockets journaled in the supports, sheaves mounted co-aXial with said sprockets, a trip carriage adapted to dump said buckets, a

cable connected to said sheaves and trip carriage, a clutch connecting each sheave with a source of' power, and means adjacent said trip carriage to cause it to throw the,r clutch in and out. i

4. A link in a conveying mechanism comprisingl a pair of opposed link members, a pair of axles joining the ends of said link members, Wheels rotatably mounted on the axles, a dumping bucket pivotally mounted intermediate the rails, said bucket having a triangular reinforcement at each end, a plurality of rollers arranged on said reinforcement, said rollers being adapted to :[irst invert and then right the bucket, said last mentioned means comprising a trip carriage, i

the trip carriage including a member having an inner and an outer trackvvay at either side, u'pon which said rollers may engage.

In testimony whereof, I hereunto afiX my signature. v

WILLIAM E. PHILIPS.
