CHARLES J. SAMUELSON, OF CHICAGO, ILLINOIS.

CONVERTIBLE HOIST-BUCKET.

Specification of Letters Patent.

Application filed August 27, 1910.

Patented Nov. 7, 1911. Serial No. 579,203.

To all whom it may concern:

Be it known that I, CHARLES J. SAMUEL- soN, a citizen of the United States of America, and resident of Chicago, county of Cook, and State of Illinois, have invented a new and useful Improvement in Converti ble Hoist-Buckets, of which the following is a specification.

My invention pertains to hoisting machinery, and particularly relates to the buckets or carriers utilized in connection with such machinery.

The objects of my invention are principally to provide a hoist bucket in which are combined all the essential features of both a hoist bucket and wheel barrow in which these dilfering essentials, while clearly diflerentiating from each other in their individual functions, are nevertheless cooperatively utilized without change to'produce a material transporting means of great adaptability and of maximum capacity with minimum floor space. In a word, to produce a hoist bucket of the highest efliciency at a low cost.

I have illustrated in the drawings, which accompany and form a part of this specification, two embodiments of my invention; one especially adapted to the conveyance of mortar, sand, etc., and the other adapted to the transportation of brick, tile, stone, etc.

Figure 1 is a rear elevation of my improved bucket for use with mortar, sand, etc. Fig. 2 is a side view of the same; Fig. 8 is a rear elevation of my improved bucket for use with brick, etc.; Fig. 4 is a side view of the same; Fig. 5 is a perspective view of my improved bucket illustrating an alternative method of hoisting the same.

Referring to Figs. 1 and 2 in which like numerals denote corresponding parts throughout, receptacle 1 is made from heavy sheet steel and is built in the form shown in two pieces, one of which forms the back and two sides, while the bottom is made of one piece riveted in place. The handles 1 are formed from a single section of iron piping and are bent to the form shown. The handle is rigidly attached to receptacle 1 by straps riveted in place. A portion of the handle extends downward and forward under the front portion of the receptacle 1 and serves, with the wheel 3, as a means for supporting the barrow in a vertical position. The wheel 3 is pivoted in housing 2 which is riveted to the bottom and back of receptacle 1. A rest 5 is pivoted in a pair of lugs 5 which are riveted to the sides of receptacle 1. A chain 6 attached to rest 5 and receptacle 1 is of sufficient length to allow rest '5 to assume a substantially perpendicular position with respect to the back of receptacle 1, when the barrow is rotated about the pivot of wheel 3 backwardly to a substantially horizontal position. The conformation of the receptacle 1 is such that the desired load of material will not overflow the receptacle in either of its possible positions of rest, 2'. 6. when it is in substantially a vertical or horizontal position.

As shown in the figures, a portion of the handle forms a beading or finish for a part of the edge of the opening of receptacle 1, while the edges, not so beaded, are crimped around a wire, thus giving a substantial finish to the edge of the opening. I have illustrated in Figs. 1 and 2 one method of hoisting this form of bucket which consists of the rope bail 7 and the hoist rope and hook 8. The hoist rope 8 may be reeved through a pulley upon the work under construction and the bucket hoisted in this well 1 known manner to any desired level, when it may be readily detached from the hoist and wheeled to any desired portion of the work.

Referring to Figs. 3, 4 and 5, the receptacle 11 is formed substantially rectangular from two plates of sheet steel, one of which forms the back and two sides, while the other forms the bottom, which is riveted in place to form a rectangular receptacle of four closed sides. A wheel 13 is pivoted in a housing 12, which is riveted to the bottom and back of receptacle 11. The handles 14: are formed from a single length of piping 'bent into the form shown in the figures. The handles are rigidly attached to the harrow by means of straps riveted to sides of receptacle 1].. A portion of the handle extends downwardly and forwardly to form, with the wheel 13, a means of vertical support for the barrow, as in the barrow just described. The horizontal rest shown at 15, 15 and 16 is in all particulars similar to that shown at 5, 5 and 6 in Fig. 2. The rope bail 17 and hoist rope 18 are shown with this form of bucket to illustrate one method of hoisting the same.

In Fig. 5 is illustrated a method of hoisting which very clearly shows the merits of my device. A pair of angle irons 35-36 are erected in the area-way or well left in a building under construction for the operation of the hoist and serve as a vertical track for the operation of the elevator formed by the platform 29, braces 37, 38, 39 and 40 and wheels 41 and 42. These wheels 41 and 42 are pivotally attached to the extremities of the arms 37 and 38, which are rigidly attached to corners of platform 29 and bail 27. Bail 27 is formed of heavy strap iron and is attached to the platform 29 and braces 39 and 40. A swivel hook and hoist rope 28 serve as a means for hoisting the elevator. A wheel guide and stop 34, together with the stops 32 and 33, all of which are attached to the platform 29, serve as a means for correctly positioning the barrow 11 upon the platform 29 with the least possible attention on the part of the workman. A second pair of stops 30-31 are used in connection with the wheel guide 34 and serve to correctly position and hold the barrow illustrated in Figs. 1 and 2.

It will be seen from inspection of Fig. 5 that the hoist barrow of my invention may have a maximum capacity and, at the same time, for that capacity occupy a minimum floor space. It will be further noted that the ease with which the barrow may be adapted to either a hoist bucket or wheelbarrow, together with the facility and despatch with which it may be placed in position upon the platform constitutes a great saving of time in the operation of hoisting and thereby increases the efliciency of the hoist.

It will be observed that with my device the center of gravity of the load is low and the design and placing of the handles upon the receptacle are such that the bulk of the load falls upon the wheel and not upon the workmens arms, as is the case with most modern barrows. Further, it will be observed that the handles may be embraced with the arms and grasped near the receptacle, the wheelbarrow being in this manner propelled in a substantially vertical position, thus further taking the load from the operators arms. The extended portion of the handles, which serve as a vertical support with the wheel, also serve the purpose of replacing the barrow upon a narrow tread or track, should it by chance leave the same, for the barrow may be tilted forward so that it may rest entirely upon the extended portion of the handles and it may then be stepped back upon the track by rotating about first one corner of the handle support and then the other in much the same manner as a trunk or heavy box is stepped along.

Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent is as follows:

1. In a conveying device, a material receptacle and a wheel attached to one end thereof, a pair of barrow handles extending from the other end thereof, said two handles being formed of a continuous rod extending along the sides of said receptacle, and laterally across the end at which the wheel is attached and constituting with said wheel a means for supporting said conveying device in a substantially vertical position, hinged legs attached to the bottom of said receptacle and constituting with said wheel a means for supporting said conveying device in a substantially horizontal position, and a hoisting bail attached to said receptacle in such manner that said conveying device will maintain said vertical position during hoist- 1n 2. In a conveying device, a material receptacle having sides, bottom and one end so conformed as to retain material when in vertical position and when in horizontal position, a wheel attached to the end of said receptacle, a pair of barrow handles extending from the other end thereof, said two handles being formed of a continuous rod extending along the sides of said receptacle, and laterally across the end at which the wheel is attached and constituting with said wheel a means for supporting said conveying device in a substantially vertical position, hinged legs attached to the bottom of said receptacle and constituting with said wheel a means for supporting said conveying device in a substantially horizontal position, and a hoisting bail attached to said receptacle in such manner that said conveying device will maintain said vertical position during hoisting.

Signed by me at Chicago, county of Cook and State of Illinois, in the presence of two witnesses.
