WHEELED scoop.

SPECIFICATION forming part of Letters Patent No. 463,571, dated` November 17, 1891. Application filed January 26, 1891. Serial No. 379.083. (No model.)

To all whom it may concern.-

Be it known that we, RHoDoM M. BRooKs and WILLIAM H. BROOKS, citizens of the United States, residing` at Molena, in the county of Pike and State of Georgia, have invented certain new and useful Improvements in Wheeled Scoops, of which the following is a specification, reference being had therein to the accompanying drawings.

ro Figure l is a perspective View of our iinproved machine with the scoo p in an elevated position ready for transportation, one of the wheels being removed for better illustration; Fig. 2, a side elevation of the same, the scoop t5 or bowl being shown in a lowered position ready for work; Fig. 3, a similar view of the machine with the bowl or scoop in a dumping position, and Fig. et a plan View of the tongue and hounds or draft-irons.

2o The invention has particular reference to that class of self-loading wheeled Scrapers wherein the scraper or scoop is lowered for work and raised for transportation by sim ply rocking an arched axle supported'on trans- 2 5 portation-wheels, the wheels being usually raised entirely off the ground when the scoop is lowered for work, as will more fully hereinafter appear. i The especial object of the present invention is to provide such machines with extremely simple and effective means for positively and automatically locking the scraper to the hounds or draft-'bars of the tongue when the scraper is lowered for work,where by all vibration and tilting of the scraper while at work is obviated and the machine is rendered simpler and less liable to injury than the machines now on the market, as will presently appear.

4o Ve will now describe one manner of carrying our invention into practice; but as the details of construction may be readily varied by one skilled in the art without departing from the spirit of our` invention we do not wish to be understood as limiting ourselves in this respect.

, In the drawings, a designates the scoop or scraper, which is of the usual or any approved construction, and which is provided with the 5o usual rearwardly-extending side handles a and the usual lug or catch a on its rear.

The scraper is swung under au arched or bowed axle Z9, mounted upon suitable transporting-wheels. The bifurcated parallel operating-arms b of the rearwardly-extending operating-leverb are rigidly bolted to theends of the arch of the axle and extended a short .distance forward of their point of attachment thereto. lhe forward end of each of these arms Z2 is pivotally secured between the up- 6o per connected ends of a pair of straps or standards c, the lower ends of these straps ori loops embracing the vertical sides of the scraper and being rigidly bolted or riveted thereto. A depending latch cis pivoted to the lever b and adapted to engage the lug d on the rear end of the scraper when the latter is raised from the ground for transportation. v

The tongue d is provided with the hounds 7o or draft-bars d', which extend rearwardly on the outside of the sides of the scoop and are pivotally connected thereto by bolts 0a, that pass through thestandards and the sides of the scoop. A transverse brace d is bolted to the end of the pole and has its outer ends (Z3 bent rearwardly and riveted to the hounds d. The rear portions of the arms cl3, being again separated from the hounds, extend back parallel with the saine inside of the respect- 8c ive sides of the scoop and are pivotally connected thereto by the horizontal bolts that 'connect the hounds and loops, the arms d3 thereby also serving as draft-bars. A block d* may be inserted and bolted between each pair of draft-bars d d3 just forward of the front edge of the scoop to separate them sufficiently to embrace the sides of the scoop.

An upwardly and rearwardly extending` spring-hook e of the usual construction is secured to therear end of the tongue and is adapted to automatically engage the catch a, secured on the rear end of the scoop, when the scoop is inverted in dumping, as shown in Fig. 3. 95

Rigidly bolted tothe upper edge of each of the sides of the scoop near its forward end is a strong loop f, the lower ends of the loops embracing the edges of the scoop and their upper looped ends extending up between the roo respective draftbars and terminating a short distance above the upper edges of the sides of the scoop. These loops have formed upon their opposite sides outwardly-proj ecting lugs f', upon which rest the draft-bars, thereby preventing the forward end ot' the scoop tilting upward when iilled or while workin g. Pivotally connected to each of the operating levers or arms b', preferably at the point of its attachment to the bow of the axle and by the same bolt, is a rod or locking-bolt g, these bolts extending forward and passing through the upper ends of the loops c and f, and, being directly over and resting on the upper edges of the sides of the scoop, they terminate at their forward ends just behind the blocks d4, inserted between the draft-bars when the scoop is elevated, and when the scoop is lowered they ext-end across the tops of thebloeks cl, thus locking them in position. The outer draft-bars d are extended rearwardly beyond their pivotal points and terminate just in front of vertical levers 7L, pivoted at their lower ends to the sides of the scoop and pivotally connected at their upper ends by means of links or rods 7L to the operatingarms b at the point of connection of the latter to the axle. These levers 7L are provided on their front edges with projections h, which are adapted to engage under the rear ends of the `draft-rods d when the scoop is lowered and the levers h are moved forward, and thereby confine the draft-rods between them and the forward ends (1,6 of the handles a', the forward ends of the handles being extended for this purpose. The handles a are bent outwardly at their point of attachment to the sides of the scoop, so as to form loops or slot-s a for the levers L to work back and forth in, as shown in Fig. l.

The pivotal rods 7L and g are slotted at their points of attachment to the operatinglevers, and their pivotal bolts are passed loosely through these slots, thereby allowing the said rods a slight movement independent of the axle and connected parts. This independent movement is useful, in that it permits the operator by means of the operatinglevers a to oscillate or work the scoop a little should it become caught while in operation without disengaging the bolt g or the locking-lever 7i, as is evident.

A bowed brace 7tis welded or bolted to the draft-rods d to assist in bracing and strengthening them, these braces connecting the rearward extensions of the outer draft-bars rl to the main portions thereof in front of their pivotal points.

ln Fig. l the scoop is shown in an elevated position as it appears when iilled and ready for transportation to the dumping-place. In this position the latch c engages under the catch a in the rear end of the scoop and the sliding bolt g and lug 7b are drawn back, so as to be free of the draft-bars. Then the machine reaches the du m pingground, the operator has simply to raise the rear end of lever ZJ sufliciently to depress the forward end of the scoop far enough to engage the ground,

whereupon the forward movement of the machine will cause the scoop to be inverted in the usual manner to the position shown in Fig. 3, in which position it will be held by the spring-hook e, as shown. After it is thus dumped the machine in its inverted position is hauled back to its work. To bring the parts back to the position shown in Fig. l, the operator releases the hook e and then. pulls back on the handle or lever b" or one of the side handles a', which throws the scoop back to the desired position.

To lower the scoop to its working position, as shown in Fig.2, the operator simply releases the latch c', whereupon the scoop will fall to the ground by its own weight, the operating-lever being drawn up to the inclined position shown and the axle being usually rocked forward suieiently to raise the Wheels olf the ground. The act of lowering the scoop, as will be perceived, pushes the sliding rods or bolts g forward over the blocks d" and the upper edges of the `connected draftbars and draws the lever h far enough forward to engage its lug 7L under the rear ends of the outside draft-bars, thus etfectually and positively locking the draft-bars to the scoop. This means for locking the draft-bars to the scoop when in working position is advan tageous over the old devices now in use,in that it is less liable to injury and derangement and is very strong and positive, serving to prevent all undue vibration of the scoop and to hold it positively to its work.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is

l. The combination, with an arched axle and wheels journaled thereon, of the operating levers 'or arms bolted to the axle, a scoop under the axle, standards connecting the sides of the scoop to the forward ends of the said arms or levers, draft-bars pivotally 'connected to the sides of the scoop, loops secured to the forward edges of the scoop, and sliding bolts connected to the levers and passed through the said loops, these sliding bolts being adapted to slide forward over the draft-bars when the scoop 'is lowered, thereby locking the scoop to the draft-bars, subst-am tially as and for the purpose described.

2. The combination of an arched axle mounted on wheels, operating-levers rigidly secured to the arch of the axle, a scoop pivotally connected to the forward ends of the levers by standards, and a tongue,and pairs of draft-bars rigidly secured to the tongue and embracing the respective sides of the scoop and pivotally connected thereto, substantially as described.
