, BUCKET oannviiie APPARATUS.

T o all 'whom it mary concern.:

ABe it known that l, CHARLES C. Pos'r, a citizen of the Dominion of Canada, and resiA dent of lVinthrop Harbor, Lake county, Illinois, have invented a certain new and useful Improvement in Bucket Carrying Apparatus, of which the following is a specification.

My invention relates to carrying-buckets lin' general, for conveying materials from one place to another, but more particularly to apparatus of this kind for receiving and delivering the materials to a concrete mixer,

such for example as those employed in putting downl concrete paving, or for other purposes.

Generally stated,the object of my invention is to provide an improved construction and arrangement whereby the bucket may I y fciency `and desii'rability'i` ofl a carryingn 35,

travel back and forth on a runway entendn ing horizontally between the place where the load is received 'and the. point `where the bucket is dumped, and whereby the bucket may be lowered at the receiving place to facilitate the loading thereof. y

Another object is-to. provide an improved construction and arrangement whereby said runway may be adjusted or'swung into 'dit` ferent positions to 'enablethe bucket to rei ceive its load.' i v It-'is alsoan object' to tails and features of construction and combucketeapparatus of this particularcharacter..

d To the foregoing andfdther. iisefulends,

my invention consists in matters hereinafter set' forth and claimed.. I

Fig. '7 is au enlarged side elevation ot the bucket and its supporting mechanism, showng` the gate of the bucket in closed posiion.

Fig. 8 is a view similar to Figui, showing the gate of the bucket in open position.

'ris thus illustrated, my invention coinprises a body .A upon which the concrete inixer B is mounted, said body being provided with caterpillars a; or other suitable traction devices, so that the entire mixingplant, including the engine C, mounted on said body; may be moved from place to place. The said mixer has a receiving-hop per o through which it receives the materials tobe mixed. An upright frame D is provided at its upper endwith a swivel d for the horizontally disposed runway E, which latter is/adapted by this arrangement to swing around in a horizonml plane. Said runway is jointed at e, so that its outer endportion can inove up and down, and this outer end-portion which forms an extension is supported by an arch-like structure F having the lower ends thereof provided with These.

wheels f to travel on the ground. wheels are provided with forks G which `are connected with the Aarch l? in such manner that they can be turned about vertical axes, 1

and a worm-gearing g is provided for ea h fork-spindle, whereby these wheels can be vMturnedzto the right or to the left to facilitate the sbiftiii of the runway into the da sired position. lie bod A is also provided with an upright frame H which provides a transverse track .it for the wheel or 'roller l, which latter is mounted in suitable bearings on the Arunway E, so that said wheel travels vided with braces@ connected at their upper ende with the outer end ,of the runway E, so that the arch issuitahly braced and held in osition. i

'"heburket l is provided at its lower end vwith a gate j which is pivoted at 2, and this back and forth on the track fi when the ruiiy wayfis shifted laterally'. The arch F is pro-f ietl buch-et. 4i traveler K is provided with wheels il: which travel on the runway E, in

any suitable manner, and this traveler is provided with two sheaves i' and @,disw

iia

6,0 vthe gate (see Fig. 8).

Q, messes der the sheave 9 and then over the sheave fr,

in the manner illustrated. The runway 1s provided with depending arms L having 10 pivoted stops Z at their lower ends, and the arm 13 is rigid with the arms L and provided with a roller 14 at its end. The traveler K is provided with a cam 15 to engage the roller 111 during the automatic closing 15 of the gate 7' (see Fig. 7,) as will hereinafter more fully appear. The links 3 have upperend-portions 16 which engage the stationary stops 17, when the bucket approaches the hopper b, so that the toggle-joints 6 will be 20` operated to lowerl the ate (see Fig. 8). After the load has been discharged from the bucket into the hopper, and the cable con.- vnections are operated to reverse the motion of Ythe bucket, the roller X, which is mounted on a stationary support adjacent the hop per, engages the under side of the gate to throw the latter upward into closed position. Then the upper endportions 16 of the links 3 engage the stops'l, and the cam 15 engages the roller 141, so that the togglejoints 6 are. brought past the center and against the stops 18 on the sides o the bucket, in which positions the toggles are selisustainiugand operative to hold the gate -in raised or S5 closed position. The-cam 15 releases the roller 14k at about the time theV toggles G strike the stops 18, so that the arms Lthen swing in the direction in which the bucket is traveling, allowing.;` the` portions 16 of the links 3 to pass out from under the pivoted `stops Z, it being" observed that the latter are held by shoulders 19 on the arms L against pivotal movement relative to said arms 'in this direction. The travelervl( is provided 4o with means 2() to engage the portions 2l. on the bucket, thereby to steady the bucket and prevent it from upsetting` while it is traveling back and forth along the runway. lWhen the bucket againl travels toward the hopper b, the portioiiis 16 engage the stops Z, andwhile the cam 15 is passing; under the roller 14;, and while the arnis L are held sta l tionary at this time, it will be seen that thestopsl swing freely in this direction, whereby these stops do not exert any pressure against the toggle-joints, allowing the lat` ter to pass under and approach the stationary stops'17, so that the latter then trip the toggle-joints, causing the latter to release The cable arrangement traveler` K along the runwayE, and whereby the bucket is raised and lowered by allowing the cable 12 to rise andall between e5 the sheaves 7 and 8 (the sheave 9 being sup for operating the ported in a loop of said cable) is as follows: The cable 12 has itsy outer end at tached to the outer end of the booni or runway E', and its other end-portion extends downward over the sheave 22, through the hollow swivel (l, and finally to the winding drum-mechanism M on the body of the rnachine. The cable 23 is fastened to the traveler .K and extends rearward and over the sheave 2li and finally to the winding drum- 7 5 mechanism, whereby the travelerl may be pulled toward the hopper. The cable 25 A'is attached at one end to the traveler, extends forward and around a sheave 26 atthe outer end ol the runway, and then rearward to the hollow swiveliol, and then downward over the other sheave 27 and finally to the winding drum-mechanism M, so that when this cable `is wound up on one of the drums Y the traveler is pulled toward the outer end of the runway. Three sheaves 28 are ar- ,ranged just below the hollow swivel cl, on

the runway, to support the three cables thus provided. When theicable 25 is operated, the traveler and the bucket are pulled toward the outer end oi the runway, and by then reversing the drum for the cable 12, so that the loop in this cable is lengthened, the bucket will be lowered to receive the load. Then the cable 12 is; wound on its drum of 95 the mechanism M, and thisraises the bucket with the loadtherein. The drum lor the' cable 23` is then operated to wind this cable thereon, and the drinn for the cable 25 is rotated backward, whereby the traveler and bucket are pulled toward thehopper. With this arrangement, it will be seen, the bucket can. be loweredv at any place or at anypoint along' the length of the runway.

it will be seen that the bucket is dumped 15 automatically by simply bumping it against the stop 17, and that while in dumping position it isheld by the portions 20 and 21, previously explained, against tilting move- `rnent on the traveler. No'special operation 110 is necessary for dumping;- the bucket when it arrives in dumping` position, and the bucket thus 'adapted to automatically dump its load, is held by the portions 2O and 21 against tilting' or rocking while traveling 115 along in elevated position. The entire machine is portable, and can travel along thev street, so that materials can be picked up anywhere, or wherever convenient, and carried by the bucket to the rotary concrete mixer. A
