Specification of Letters Patent.

' Application filed flctooer 6, 1914. Serial No. 865,335.

To all whom it may concern:

Be it known that I, PnILIP A. Konrnznvo, a citizen of the United States,- residing at .Milwaukee, in the county of Milwaukee and State of Wisconsin, have. invented certain new and useful Improvements 1n Conveyer Apparatus, of which the following is a specification.

In my Letters Patent, reissued September 16, 1913, Number 13,617, is described improved conveyer means in the form of a concrete distributor especially designed for use in'delivering mixed concrete from a mixer togasuitable point of deposit. The

'machine of the above Letters Patent has been found. of unusual practical value in bind :economically eifecting a disf materials over a suitable area. jpecial object of my present in-. rovide a conveyor mechanism e used in connection with the vention to adapted :to

I "distributing means of the above patent whereby instead of requiring the manual loading of the concrete mixer as by deposit v will in part hereinafter become apparent ing wheel barrow after wheel barrow in a loading bucket adapted to dump into such mixer, .I am enabled to employ mechanical means solely, such as a grab bucket and suitable controlling mechanism, whereby to effect the loading operation above-referred to. The conveyer mechanism of the present invention while especially intended for as sociation with concrete mixers may, of course, be employed in many other 'ways in which conveyersare generally utilized.

Among the objects in view in respect to the particular improvements hereinafter set forth in detailare the effective handling and delivery of concrete materials by mech anism characterized by ease and simplicity of control; the provision for stability of the supporting part and the relative disposition of parts for insuring economical cooperation.

With these and other objects in view, as

and in part be stated, the invention comprises a framework, a. mixing drum sustained thereby, a boom movably carried by the framework, :1. load conveying carriage movably mounted on the boom, means for shifting the carriage, and means for de livering the load conveyed by the carriage to the mixing drum. i v

The'invention further comprises a frameworln-a boom pivotally carrid'thereby and having a trackway, a brace sustaining the free end of the boom and pivoted coaxially with the boom, and a load carrier movable .1

along the boom past the brace, the brace comprising a single member at its lower portion and being bifurcatedat its upper portion for allowing the passage-of the load 1 carrier. e

The invention comprises certain other novel constructions, combinations, and arrangements of parts as will be hereinafter fully described and claimed.

engine 6 is sustained by the frame 1 and Y may be of the internal combustion type or may be a steam engine supplied with steam from boiler 7 also sustained by the frame 1. Engine 6 isgeared to drive a main drive shaft 8 which extends substantially I throughout the length of frame 1 and is provided with gears 9 meshing with gears 10 formed on the periphery of drum Appropriate controlling clutch and transmission gear mechanism are adapted to deliver power from shaft 8 to the rear wheels 2 for causing the structure to act as a tractor for purposes of transportation."

Fixed in the framework 3 above drum disapiatform l1; facilitating access'by an operator'to various parts of the apparatus.- A hopper 12 is fixed in the framework 3 in advance of the platform 11 and is formed with a chute 13 discharging into drum 5. Hoppers 14, 14; are arranged above hopper 12 and sustained in the framework, each of the hoppers 14 being provided with adischarge chute 15 controlled by a gate 16 res and disposed to direct the discharge into the hopper 12 the two gates 16 being fixed to an actuating shall: 17 for being manually operated.

In the uppermost portion of the framework 3 a boom 18 is journaled and provided with an extended terminal portion 19 formed with a horizontally arranged and arcuate rack 20 with which meshes the new sled gear 21 carried by shaft 22 journaled in bearings (3' fixed to frame 3. The rear end of shaft 22 carries a bevel gear 23 meshing with a similar gear 24 tired to a vcrtically disposed shaft 27 The lower poi tion of shall extends past shaft ls and carries oppositely disposed bevel gears/27 and 28 loosely mounted on the shalt and adapted to be connected therewith alter nately by a clutch ineuiheufzfl slidingly mounted on shaft and disposed to engage cooperating clutch teeth on the contiguous faces of gears 27 A bevel gear 30 is fixed'to shaft 8 and meal 28, so that when clutch Ln) engages gear 2% boom 18 will be swung in onedirection, an l when the clutch engages gear 27 the boom will be swung in the opposite direction. Boom '18 consists of a pair of parallel beams fixed together at their inner ends by'being bolted to or otherwise connected with an intel-posed block having the rearextension 1.9, and said beams extend forwardly to the outer end of the boom where they are con nected by a cross beam, preferably a chan nel plate 31. Plate 31 extends laterally beyond the beams comprising boom 18 and at achot' its ends is by a beam 32, the beams extendingparallel to each other and inclined downwardly and rearwardly to a cross channel plate 33 which fixed to the lower end of the beams at ends. and at its center being fixed to a beam which extends at the same angle as beams down to a point in axial alinement with the pivot of boom 18, at which point the beam is pi-votally sustained in the frame so as to swing with the boom,

the said beam 34; and beams 3.? an inclined brace for the boom,

A carriage 35 is provided with flanged wheels the beains'o't boom 18 and is adapted to travel longitudinally of the boom. An ordinary grab bucket 36 is com prising ranged to be sustained by, to depend from ms with gears 27.

through which is extended a pin 39 engaging a link' lt); the latter extending upwardly into position for engaging hooks 41 carried by operating levers 42 pivoted to the body of carriage 35. Springs 43 engage the upper portions of the lovers for normally i'naiutaining the hooks in engagement with link 40. The link 4:0 is preferably constructed in the form of a "l' with the head of the T arranged horizontally to engage hooks ll and its body pendent. The upper end portions of levers l! are connected by cross pin 44, which is engaged by a cable l5 extending from the cross pin ton 'ardly along the boom 18 to and about a pulley 4G journaled at the tree end of the boom 18. Cable 4:5 extends thence rearwardly along the boom 18 and is passed about a guiding pulley 47, about pulley 4:8 and downwardly about a pulley l9 journaled on shaft 8, and thence upwardly about a pulley 50 and about a pulley 51 to the cross pin 4-4. Thus the carriage 35 is free to ride along the boom while the levers remain in their bucket supporting position the cable 45 merely shifting longitudinally to an extent responsive to movements of the carriage. It will of course be obvioijis however, that an appropriate pull on cable 45 will swing levers 42' on their pivots and thus move hooks 4-1 out of engagement with link 40, releasing the bucket and allowing it to drop or open according to the paying out of the bucket supporting cable hereinafter described. The pull on cable 45 may be effected in any of various ways, as manually, or, when the carriage is moving inwardly, by the use of a brake applied to pulley 49 for stopping the longitudinal travel of cable as while the carriage continues to move which will give the effect of a pull on the cable since the pivot of levers 4-2 is moved relative to the point of engagement ll of cable 45. v

The controlling pulleys of the bucket 36 have a cable 52 laced therethrough, one end of the cable being connected to a fixed part of carriage 35 and the other portion of thecable beyond the pulleys of the bucket extending past guiding pulleys 53, 54: and F5 and thence downwardly to winding drum 56 mounted on shaft 8 and adapted to be driven thereby through a clutch 57. brake preferably of the band type, ena portion of the drum 56 for controlling rotation thereof. A cable 59 is fixed to carriage and extends outwardly alon the boom 18 to and about an idler pulley 60, and extends thei'ice rearwardly along the boom to and about guiding pulleys 61 and 2 and thence downwardly to an operating drum 63. Drum 63 is carried by shaft 8 and is adapted to receive power therefrom through clutch 64:.

the parts being 1n the posistrip 66 is fixed to the upper arm of bracket and extends on an incline rearwardly and is fixed to frame? for aiding 'in resisting stresses longitudinal of the boom 18.

A discharge chute 67 extends rearwardly from within drum 5 to a delivery chute 68 In operation, tion indicated in open, drum 63 and thus exerting a pull on the carriage 35 which causes the carriage to be drawn outwardly along boom 8, this Fig. 1 and clutch 57 being movement. continuing until the carriage either arrives at the outer end of the boom or above the point of deposit of the material to be delivered to hopper 14:. Upon reaching this point the cable 45 is given a pull for swinging the levers/l2 to the bucket releasing position, the carriage at the same time being stopped by opening clutch 64. Brake band 58 is of course released during the outward travel of. carriage 35 and being left open, cable 52 continues to feed out wardly as the bucket 35 descends under its own weight. When the bucket has reached the supply of material and the scoops have engaged a portion thereof sufficient for constituting a load, the clutch-57 is closed and the drum 56 thus driven for reefing in the I cable 52 whereby the bucket is closed in the usual manner and then drawn upwardly until link 10 passes the beveled under surfaces of hooks 41 and has its head resting upon the hooks. The carriage 35 is provided with pendent sheets or plates between the beams of boom 18, each plate. being notched as indicated at 35 for the reception of the head of link 40 and the edges of the plates are beveled to guide the head into the notch for insuring engagement of the head with the hooks and for maintaining such engagement. Assoon as the bucket has reached this position the continued reefing in of cable 52 causes the carriage 35 to be drawn-inwardly along the boom 18 until the bucket arrives at a point above hoppers 14 whereupon the band brake 58 is set and j-pended' above the hoppers. are journaled in appropriate brackets fixed Pulleys 47, 5 1, 61 and 54 are' mounted to rotate about a vertical axis,

clutch 6a is closed for actuating the the clutch 57 released. This holds the-parts in inoperative position with the bucket sus- When the'hopr is ready to receive thecharge from the ucket, band brake 58 is released and the bucket allowed to automatically dump its load into hoppers 14. Gates 16 are opened ;-by actuation of an appropriate lever 17 connected with shaft 17 see Fig. 3, for allowing a charge to be delivered to the hopper 12, all, or any appropriate portion of the load delivered to the hopper being permitted to pass through chutes 15 before the gates. 16 are closed. A gate 13 is preferablyprovided for chute 13 and suitable means not -forming any part of this inven; tion ara'provided so that the charge admittedjtmthehopper 12 can be delivered to the drum5 at-an appropriate moment consistent with conditions within the drum at the .will of the operator. When further loads are'to be" delivered by the bucket, the operation is repeated. In the course of use, different materials will naturally be deposited'gatldiiferent points laterally of the machine and to enable the requisite lateral movement; of bucket 36 for causing the bucket to approach the particular .point of supply, the shaft 2-2. is actuated for swinging boom 18 angularly to therequired .position.
