Application lcd May 17, 1915. SeriaI No. 28,693.

To all whom t may concern Be it known that I, JAMES W. BROWN, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain l@ distributing apparatus and has been elaborated with especial reference to being'used in connection with the delivery mechanism for the product of a concrete mixing' machine, though it is capable of a wide `variety of other applicationsand uses. It has especial adaptability to` apparatus in which Vis employed a conveying receptacle arranged to traverse a rigid over head support such as a swinging crane or boom; and it consists `of means for changing and adjusting the angular position of such support with reference to the horizon, through power-driven connections of novel character.

In the accompanying drawingsjI have illustrated one embodiment of the invention in apparatus for` receiving the product of a concrete mixing machine and'delivering it to the place where it is to be used.

In such drawings-Figure 1 is a side so elevation of apparatus embodying my invention. Fig. 2 is a view partly in section and partly in end elevation, the sectionlbeing taken on the line II--II of Fig. 1. Fig. 3 is a vertical sectional view through the driving mechanism bywhich the conveyer is caused to be movedback and forth, and by which also the inclination of the track along which the receptacle travels may be varied. Fig. 4 is a detail sectional view of the winding drum for the cable that adjusts the boom or receptacle track vertically, and of .the gearing that drives it.

In the drawings 2 indicates a portion of a concrete mixing machine of the rotary drum type, and 3, the framework located near the discharge end thereof.

4 indicates a bracket supported by the framework, in which is mounted -a vertical pivot 5 that carries at its lower end a casting 6, in which is supported, by a horizontal pivot 7 a crane or boom`8 that constitutes the track or way along which is caused to travel the carriage 9 of a conveying and distributing receptacle 10, the latter being in the form of a suspended bucket with bot- 'in a bracket 13 supported by the framework 3. From the drum the cable passes over a head pulley 14 mounted in a pivoted support 15, thence around a pulley 16 carried by the boom and back to the pivoted support 15 for the head pulley, where it is secured.

17 indicates the, main counter-driving shaft of the concrete mixing machine, to which is secured a sprocket wheel 18, from which power is transmitted, by means of a chain 19, to a sprocket pinion on a horizontal shaft 21. The movable member 22 of adouble friction clutch is supported upon this shaft and rotates therewith. There are two beveled gears, 23, 23, supported loosely upon this shaft. the clutch member 22 being between them, and to such bevel gears are secured the clutch members that respectively coperate with the movable clutch member 22 accordingly as the latter is moved in one direction or the other. The bevel gears mesh with a bevel pinion 24 secured fast upon a vertically disposed shaft 25, that passes axially through the vertical pivot 5 of the boom, and carries at its lower end a bevelpinion 26. This latter meshes with the .bevel gear 27, to the hub of which is secured a sprocket wheel 28 that engages with and drives a chain belt cable 29 that .which the operator controls the movements of the traversing cable, it vbeing connected, through a suitable train of devices, with the movable element 22 of the clutch. It will be readily understood that when the handle is moved into one position the cable is driven in a direction to cause the receptacle 10 to be traversed outward; when moved into another position to be traversed inward; and

when moved to a mid-position the clutch elements are disengaged and the cable and the parts it moves come to rest.

3l is a bevel pinion engaged by the bevel wheels 23 and preferably arranged diametrically opposite the bevel pinion 24. It is secured fast to a shaft 32. The shiftable member 33 of a jaw clutch is secured to the upper end of this shaft by a spline or feather; and a clutch-shifting hand lever 34 is so supported and connected therewith that its movements may be manually controlled.

35 is the clutch member arranged to be engaged by the clutch member 33. It is connected with a worm 36 secured fast to a shaft 37 supported in the bracket 13, being preferably integral therewith. The worm 36 meshes with a worm wheel 3S and is connected with and drives the drum l2 upon which is wound one end of the cable 11. hand wheel 39 for turning the drum l2, and thus adjusting the boom manually is secured to the upper end of the shaft 37. A spring 40 is employed to over-balance the weight of the hand lever 34 and Cause the parts 33 and 35 of the clutch to normally separate.

Means are provided for adjusting the boom 8 about its vertical axis of support such as the worm gear segment 4l and the manually operated means 42 for driving said gear.

The operation of the mechanism described is as follows: lVhen it is desired to lower the outer end of the boom 8 the conveying bucket and its carriage are moved to their eXtreme inner positions, as indicated in Fig. l. The operator then brings the clutch members 33 and 35 into engagement, and thus puts the drum l2 into driving connection with the train of gearing, 23, 24 and 31. He next shifts the clutch member 22 and connects the gearing just referred to with the. drive shaft 17 in such way that the cable 29 is driven in a direction to move the distributing bucket outward along the boom; and, at the same time, the drum l2 is rotated so as to unwind the cable 11, allowing the outer end of the distributing boom to be lowered. If the desired angular adjustment of the boom is not secured by the time the bucket carriage arrives at its outer limit of traverse, 'the operator disengages the clutch jaws 33 and 35i and, while they are disengaged, reverses the clutch 22, causing the bucket vand its carriage to be returned to the inner end of tho boom; when the operations described may be repeated and continued until the desired adjustment has been secured.

In order to raise the outer end of the dis- Y tributing boom the bucket is first run out to the eXtreme outer limitol:I its travel along the boom before the clutch members connecting the drum with the driving mechanism are brought into engagement. rilhen with the bucket in this position these clutch members are caused to engage and the main power transmitting clutch member 22 shifted so as to drive the parts in a reverse direction to that already described, causing an inward traverse of the distributing bucket and a raising of the outer end of the boom. These movements are repeated if necessary until the desired angular adjustment has been effected.

When mechanical power is not available, as when the prime motor (not illustrated in the drawings) is not in operation, the vertical adjustments of the boom may be effected manually by means of the hand wheel 39.

What I claim is:

l. In a conveying and distributing apparatus, the combination of a rigid boom, a conveying receptacle supported by the boom and adapted'to traverse thesame, a horizontal pivot on which the boom is mounted, a cable connected with the boom for sustaining it in an extended position, a winding drum to which the cable is secured, means for causing traverse of the conveying receptacle along the boom, driving gearing for the saidmeans, and gearing for driving the said winding drum, taking power from the gearing that causes the traverse of the conveying receptacle and including a clutch by means of which the connection with the drum may be made or broken at will.

2. In a conveying and distributing apparatus, the combination of a rigid boom supported upon a horizontal pivot, a receptacle supported by the boom and adapted to traverse the same, a cable connected with the boom for sustaining it in an extended position, a winding drum to which the cable is secured, a power driven shaft, a train of gearing for causing the traverse of the receptacle along the boom connected directly with the said shaft, and another Atrain of gearing extending directly between the said power driven shaft and the said cable drum including a manually operated clutch by which the driving Aconnection with the drum may be completed or'broken at will.

ln testimony whereof I have hereunto set my hand.
