PATENT WINFIELD SCOTT RYNEARSON, OF BOISE, IDAI-IO.

DERRICK AND DUMPING DEVICE.

SPECIFICATION forming part of Letters Patent No., 665,757, dated January 8, 1901.

Application'led June 19, 1900.

To @ZZ whom it' may concern:

Be it known that I, WINFIELD SCOTT RY- NEARSON, a citizen of the United States, and a resident of Boise city, in the county of Ada and State of Idaho, have invented a new and Improved Derrick and Dumping Device, of which the following is a full, clear, and exact description.

The invention relates to that class of machines which are provided with a mast mounted to turn in a suitable base and a boom carried by the mast, together with a scoop which is supported from the boom and is arranged for dumping or for carrying a load.

The purpose of this invention is to simplify the construction of machines of this character and enable them to be readily placed in position wherever desired; and a further and main purpose of the invention is to provide a locking device capable of holding the scoop in position to carry a load and enable the scoop to, be manipulated to receivev a load and also to provide means 'for so operating the fastening device that the scoop may be quickly brought to a dumping or discharging position.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter' fully set forth, andpointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective View of the improved device. Fig. 2 is a horizontal section through the lower portion of the mast, showing the base structure in plan view. Fig. 3 is a vertical section on the line 3 3 in Fig. 2 through the base structure of the device, illustrating the mast in dotted lines as carried to a horizontal position. Fig. 4 is a side elevation of the scoop and a section through the locking device for said scoop, showing the scoop in position to carry a load; and Fig. 5 is a view similar to Fig. 4, illustrating the scoop in its dumping or discharging position.

The base B of the device is usually attached to beams A, adapted to rest upon the ground or upon the bed of a wagon, and the'base B, which is in the nature of a frame, is connected senti No. 20,852. on mode.)

with the beams A through the medium of hinges 10, so that the base and parts carried thereby may be carried in direction of the ground for rigging purposes or for repairs or for other purposes. The base B may be held in its horizontal position on the beams A by any suitable` means. For example, a hasp 1l may extend from the superstructurenamely, the beams A, connected by suitable cross-bars-through a member of the base B, and a pin 12 is then passed through the staple, to which pin a rope, cord, or chain 13 is attached.

A pulley 14 is located at each corner of the lower .structure upon which the base B is mounted, as shownin Fig. 2, and a hoist-rope,A

to be hereinafter referred to, is passed over any one of the pulleys 14, as occasion or convenience may demand. Braces 15 extend upward from the base B and are connected at their upper ends to a ring or collar 16. A mast C is passed loosely through this ring or collar 16, and the lower end of the mast is mounted to turn in the bottom structure formed by the cross-bars and beams A, while the Lipper end of the mast is mounted to turn in a cap 17, to which cap guy-ropes 18 are secured, and these ropes are led to the ground when the mast C is in an upright position and are secured by pins 19 or equivalent devices.

rlhe mast is preferably tubular and is made in two or more telescopic sections`20 and 2l, the upper section being adjustably heldin connection with the lower section by a collar 22 and a set-screw 23, while a second setscrew 24, located in the lower section 20, is also utilized to engage with the upper` section, thus preventing undue strain being brought to bear upon the upper set-screw 23. A pulley 25 is held by a clip or suitable means to the upper section 2l of the mast at a point between its ends, as shown in Fig. 1, and at a point between the ends of the lower section 2O of the mast a second clip 26 is secured in any suitable or approved manner. One end of a boom 27 is hinged to the clip 26, the outer end of which boom 27 is usually provided with a head-plate 28a, extending above and below the boom. An adjusting-rope 28 is attached to the upper end of the head-plate 28a, and the adjusting-rope is passed over the pulley 25 and down to the IOO lower portion of the mast, where it is attached to a cleat 29 of any description. This adjusting-rope 28 is adapted to regulate the inclination of the boom 27, and preferably a sliding noose 30 is provided in this adjustingrope 28, through which noose the mast C is passed, so that there will be no undue strain on the cleat 29.

A block 3l is attached to the lower end of the head-plate 28a, secured to the outer end of the boom 27, and near the inner end of the said boom 27 a second block 32 ,is placed. A hoist-rope 33 is passed over the pulleys in the blocks 3l and 32 and is carried downward over one of the base-pulleys 14 and `from thence to any source of power'. Thehoistrope 33 is att-ached to a lockingv device D for a scoop E, this locking device and scoop being best shown in Figs. 4 and 5. i The hoist-rope 33 is attached 'to the-upper end of a bar 34, which constitutes one member of the locking device D. This bar is provided with a notch 35 in one of its longitudinal edges and is provided near its upper end with a flange 36, while one end of a chain 37 is attached to the lower end of the bar 34 and to a hook 38 or the equivalent thereof, centrally located at the back or closed end of the scoop E. A casing 39 is provided for the bar 34 ot' the locking device, and this bar slides in said casing and is adapted to entirely leave it when the scoop is to be brought4 to the dumping position. (Shown inv Fig. 5.) The upper flange, 36-'on'the bar 34 limits the upward movement'of thefrcasing 39, and a plate 40, carried bythe chain 37 and located adjacent to the hook on the scoop E, limits the upward movement of the rear end of the scoop, as shown in Fig. 5. trolled latch 4l has playin the casing 39, and when the bar 34 is in the casing 39 the latch enters the notch 35 in the bar 34, as shown in Fig. 4, and the latch 41 is held iu this locking position through the medium of a lever 42, to which it is attached, the lever being pivoted tothe casing, which lever 42 extends downward to an engagement with the Lipper end of a spring-controlled keeper-bar 43, mounted to slide vertically or parallel withthe casing 39 in lugs 44, which are at one side of the casing. The keeper-bar 43 is released from engagement with the latch 42 by drawing upon a rope or cord 45, attachedtoysaid keeper-bar, at which time the spring of the latch `41 will force the lever 42 outward and will carry the latch from engagement with the notch .35 in the bar 34, and the casing 39 of the locking device will` be free to drop downward.

The scoop E is provided at its receiving end with a suitable bail46, which is placed inconnection with a'snap 47 or like device attached to the upperportion of the forward surface of the casing 39 ofthe locking device.

In operation when the bar 34 islocked in the casing 39, as shown in Fig. 4, the scoop E will normally so hang that its rea-r or closed A spring-conend will be lower than its forward or receiving end, and the rear end of the scoop may be manually raised or lowered, so as to gather up material, and handles are usually attached to the sides of the scoop 'to facilitate the gathering operation thereof. When the scoop has received its load, it is permitted to return to the position shown inFig. 4, and by pulling upon the hoist-rope 33 the boom is turned around the mast to any desired point, and said scoopis elevated at the same time. When the scoop reaches the point where the load is to be dumped, it is simply necessary to pull upon the cord or rope 45, connected with the 4keeper-bar 43, and byfthus releasing the cas-" ing 39 of the locking device from the bar 34 the casing will drop downward along the chain 37 until itstrikes' the plate 40, as shown in Fig. 5, thus `iu'ipari'iing to the` scoop E the forward andfdownward positionjshowni in Fig.

f5, which will compel thecon'tents of the scoop to slideY therefrom. Y

Havingy thus described my invention, I'
