Application filed December 30, 1909. SerialoNo. 535,645.

To all whom t may concern Be it known that I, W'ILLIAM HENRY INsLEY, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a certain new and useful Contractors Elevator, of which the following is a specificat-ion.

The object of my invention is to produce an elevator structure which may be used not only for the raising and lowering of general building materials, Wheelbarrows, etc., for the construction of buildings, but also of such character that a large dumping bucket, capable of carrying concrete, etc., may be readily placed in position upon the main frame so as to be raised and lowered and automatically dumped and returned by the vertical movement of the main frame.

The accompanying drawings illustrate my invent-ion. l

Figure 1 is a perspective view of my improved structure with the dumping bucket in carrying position; Fig. 2 a perspective view showing the bucket in dumped position; Fig. 3 is a perspective under face view of a removable platform structure.V

In the drawings, 10, 10 indicate the upright side-frames of the main frame, connected at their upper ends by a cross beam 11 provided with a sheave 12 over which the lifting cable 13 may be passed. At its lower end each. side frame 1,0 carries a transverse bar or member 14 which is preferably made of angle iron having a horizont-al arm 15, the two horizontal arms 15 being projected toward each other and the side frames being connected by cross bars 16. Each side frame is provided with guide flanges 17 adapted to straddle the vertical guides 18.

rIhe `structure is such that a flooring 19 may be readily laid upon the horizontal arms 15 of the bars 14 so as to receive loads of any desired kind. It is convenient to have this flooring made into a single structure which may be readily laidin place and such .structure may, if desired, have one or more pins 21 in its lower face to enter one or more of the holes 22 which are formed in the horizontal arms 15.

j The dumping bucket 23 is formed of a pair of substantially parallel sides 24 and a bottom sheet 25 in such a manner that the bucket is provided with an arc-shaped lower supporting portion which, at each end, is

flanked by an arc-shaped angle 2.6 which angles rest and roll upon the horizontal arms 15 of the elevator frame. In order to keep the bucket in place the angles 26 are provided with pins 27 adapted to ent-er holes 22 as the bucket is rolled on arms 15. While such a supportfor the bucket permits a rocking of the bucket to some extent, such rocking would not be sufficient to insure aperfect dumping of the contents of t-he bucket and therefore the bucket, at its forward or dumping side, is provided with two pairs of brackets'28 each pair of which is adapted, when the bucket is rocked forwardly, to straddle the adjacent cross bar 16 and thus hold the bucket laterally in place as it swings downwardly and forwardly over the adjacent ends of bars 14. Stop-arms 31 are provided to engage aportion of the side frames 10, as clearly shown in Fig. 2, to limit the dumping movement of the bucket.

In order to automatically control the dumping movement of the bucket by -the vertical movement of the elevator frame, I provide bucket 23, at one side, near the top, with a roller 32 adapted to engage a vertical track 33 and an upwardly and outwardly extending track 34 which forms an extension of the upper end of track 33.

In operation, with the parts in the position shown in Fig. 1, the bucket is held in position'by pilas 27 lying in holes 22 and also by roller 32 which isiin engagement with track 33. As the structure is moved upwardly, roller 32 will be brought into positionwhere it mayl pass outwardly along the track 34 and the weight of the material in the bucket, as well as the unbalanced weight of the bucket itself, will cause the bucket to roll first upon arms 15, the pins 27 prevent-ing any transverse slippage, and then to swing downwardly and forwardly on the forward ends of bars 14, the brackets 2S straddling rod 16 and 'preventing transverse displacement. When the elevator structure is lowered, the bucket will be forced back to its normal position by t-he action of roller 32 upon tracks 34 and 33.

This construction is very useful in the erection of the concrete of reinforced concrete buildings because the concrete may be readily deposited in considerable quantities in the bucket and quickly delivered at desired points in the upper stories, as the work progresses. It is necessary, however, to elevate the relnforclng materials preliminary to the delivery of the concrete and with the .available for ordinary hoisting purposes.

' The bucket, however7 may be very readily replaced and used at any time. With this construction therefore it is unnecessary for the building contractor to provide himself with several elevators some of which are only capable of hoisting the concrete while others are only capable of hoisting other arf ticles.

- I claim as my invention 1. An elevator structure comprising a main frame having horizontal tracks be tween the vertical members thereof and adapted to receive' a flooring structure, Iand a dumping bucket having a Haring open top, an inclined discharge sideand a round bottom rollingly and removably mounted on said tracks between said verticalmembers, and a projection carried by the bucket near its upper end and outside of the vertical supports of the main frame in the dumping Y direction, Said projection being adapted to engage stationary" guides to support the bucket in load-retaining position u-pon-` the main frame.

2. An elevator structure comprising a main frame having horizontal tracks and adapted to receive a flooring structure, and a dumping bucket rollingly and removably mounted on saidv tracks, saidz bucket having portions interengaging with the traclrs to prevent slippage during rolling and also having a pair of brackets adapted to straddle a cross bar of the main frame when the bucket is moved" to dumping position.

In witness whereof, I have hereunto setV my hand and seal at Indianapolis, Indiana, this seventeenth day of December, A. D. one thousand nine hundred and nine.
