These supporting .devicescoinone place to another. This carrier is mountprise a seriesot supporting bars ea ch piv-l ed for vertical movements to raise and lower oted at its lower end at 30 to an angle bracket pivotal points the supporting bars 28 extend upwardly in substantially parallel relation, and adjacent their upper ends these bars pass through U-shaped guide members 34 attached to the horizontal bars 2 and also engage a transverse angle bar 36 secured to the horizontal bars 2 of the frame, as shown in Fig. 1.

In order to hold the brick supporting fingers in horizontal position, thesupportingY bars 28 are latched in their upper positions shown in Fig. 1. The latch mechanism comprises a transverse rock shaft 38 mounted to turn in bearing blocks 40 attached to the supporting frame. This shaft carries a. series of latch fingers or dogs 42 each of which is arranged to engage in a notch 44 in the corresponding supporting bar 28. The rock shaft 38 is yieldingly actuated to engage the dogs 42 in the respective notches in the supporting bars 28 by means of one or more coiled springs 46 each connected at one end to an arm 48 projecting from the rock shaft and at the other end to a point on the frame. The rock shaft 38 is turned in a direction to disengage the dogs 42 from the notches in the supporting bars by means of a cable or chain 50 attached at one end to an arm 52 secured to the rock shaft.

The dogs 42 and the notches 44 in the supporting bars are preferably shaped so that when the dogs are engaged in said notches and a stack of brickis supported upon the fingers 22, the friction between the ends of the dogs and the contacting faces of the vnotches will prevent the disengagement of the dogs from the notches until the load upon the supporting bars 28 is relieved. This will prevent the accidental release of the load of bricks carried by the fingers until the fingers f are brought into engagement with the hori- Zontal support upon which the bricks are to be placed by the descent of the carrier.

VIn order that the fingers 22 may be swung upwardly to a slight degree with relation to the frame when the fingers engage the support upon which the bricks are to be placed, the fingers are preferably made somewhat wider adjacent their outer ends, as shown in Fig. l. With this construction when the carrier descends vertically, the wider outer ends of the fingers will first engage the horizontal support, and the further descent of the carrier will then cause the fingers to swing upwardly slightly with relation to the frame thereby relieving the pressure exerted by the bars 28 upon the outer ends of the dogs 42.

Other constructions may be employed for causing the outer ends of the brick supporting fingers to engage first the support. Thus the fingers and the latching mechanism therefor may be so constructed that when the fingers are latched in their upper or brick supporting positions, the angle between the same and the upright bars 4 will be greater than a right angle. This will cause the fingers to droop slightly with relation to the frame when carrying a load of bricks and the outer ends of the lingers will first engage the support upon which the bricks are to be placed.

The bricks are prevented from accidentally engaging between the supporting bars 28 by means of suitable abutments which also serve to limit the movement of the fingers 22 beneath the stacked bricks. One of'these abutments consists of one side plate of the angle bar 26. An abutment plate 54 also is attached to the supporting bars 28 preferably by welding the same to the bars, as shown in Fig. 1. The space between the lower edge of the abutment plate 54 and theadjacent side plate of the angle bar 26 is filled by a curved plate 56. This curved plate 56 is attached to the adjacent side plate of the cross bar 26 and may consist of an. extension of said side plate. As shown in the drawings, this curved plate is attached to the angle bar 26 by means of attaching plates 57 extending across the joint between the curved` plate 56 and the adjacent side plate of the angle bar and welded both to the curved ba-r and the angle bar. The curved plate 56 is provided with slotsf58 to receive the supporting bars 28 thereby forming the curved plate with portions projecting between the supporting bars, as shown in Fig. 2. The curved formation of the plate 56 prevents the bricks from becoming displaced between the same and the supporting bars V28 when the fingers 22 are in lowered position, as shown indotted lines 1n Fig. 1.

The construction shown in Figs. 3 and 4 is substantially the same as that shown in Figs. 1 and 2 except that the supporting bars'28 are connected in a somewhat different man'-V ner to the fingers 22, and a different con# struction is provided for preventingthe bricks from passing between the supporting bars. In the construction shown in Figs. 3 andA 4 the supporting bars 28 are connected in spaced relation by means of an abutment plate 60 to which thebars are preferably welded. The bars are pivotally connected at 62 to the fingers 22 by means of a hinge 64 one member of which is secured to the abutment plate 60 and the other member of which is secured to the angle bar 26. In this construction the abutment plate 60 and the adjacent side plate of the angle bar 26 are arranged sufliciently close together to pre` vent the engagement of bricks between the same.

The construction shown in Figs. 5 and 6 is similar to that shown in Figs. 1 to 4, inclusive, except that the supporting bars 28 are connected in a different manner with the lingers 22 and that a different construction is employed for holding said bars in elevated positions. In the construction shown in Figs. 5 and 6 the bars 28 are connected by Lamme an abutment plate 66 secured to said bars. The bars are pivotally connected at 68 with the fingers 22 by means of a hinge comprising hinge plates 7 0 and 72. The hinge plate 72 preferably extends across the several ngers 22 and is connected to each finger by means of angle brackets 76. The hinge plate preferably extends across the several supporting bars 28 and is secured to each of said bars, as shown in Fig. 5. The abutment plate 66 and the hinge plate 70 prevent the passage of the bricks between these supporting bars.

The supporting bars 28 are respectively provided at their upper ends with a projection 78 arranged to engage the upper edge of the vertical side plate of the angle bar 36 which extends across and is secured to the horizontal bars 2 of the frame. The position of each of the supporting bars 28 is controlled by means of a bar 80 having therein a series of slots 82 through which the supporting bars`28 project. The controlling bar 8O is carried by arms 84 secured to the rock shaft 86 mounted in bearing blocks 88 secured to the frame. With this construction, upon turning the rock shaft 86 to the right, Fig. 6, the supporting bars 28 will be moved in a direction to disengage the projection 78 from the angle bar 36thereby releasing the supporting bars and the fingers 22. To the rock shaft is attached an arm 90 to which is connected a cord or cable 92 for actuating the rock shaft in a direction to disengage the projection 78 from the angle bar 36. The

rock shaft is actuated in the reverse direction to restore the supporting bars to positions to place the projection 78 above the upper edge of the angle bar 36 by means of a coiled compression spring 94 interposed be.

tween the arm 90 and the frame.
