WHEELED SCRAPER..

SPECIFICATION forming part of Letters Patent No. 643,693, dated February 20, 1900.

Application filed July 13, 1899. Seria-l No. 723 ,663. (No model.)

To all whom it may conce-rn:

Be it known that I, SEL S. SPINDLE, of Kam sas City, Jackson county, Missouri, have in vented certain new and useful Improvements in Wheel-Scrapers, of which the following is a specification.

My invention relates to wheel-Scrapers of that class which are filled while the machine is in motion and are dumped under the combined gravitative action of the pan and the power of the draft-animals, the dump-boss tripping a short hook or lever to cause the dumping action to take place at the proper time; and my object is to provide improvements whereby the loading operation is effected more quickly and with less work ou the part of the draft-animals than with the old machines and whereby the machine itself will not be subjected to as heavy a strain as the old machines.

With this object in view the invention consists in certain novel and peculiar features of construction and combinations of parts, as will be hereinafter described and claimed, and in order that the invention may be fully understood I will proceed to describe it, with reference to the accompanying drawings, in which- Figure 1 represents a side View of a wheelscraper embodying my improvements, the near wheel of the same being omitted, said figure representing the machine in position for loading. Fig. 2 represents a similar view with the machine positioned for carrying the load. Fig. 3 is a detail rear view of the upper part of the machine. Fig. 4 is a detail perspective view of the trip-lever for locking the pan in its horizontal position.

Referring now to the drawings in detail, 1 designates the wheels; 2, the short stub-axles therefor; 3, collars mounted on said axles., and t the 'arched axle-frame, secured rigidly to said collars and carrying an upwardly-projecting standard 5.

6 designates a frame secured at its rear end to the collars 3 and carrying at its front end the tongue 7 and the drivers platform 8, andsecured to said platform is the bracket 9, upon which the foot-dog 10 is pivotallymounted.

11 designates the lever, having its handle portion 12 adapted to be held down by the dog 10, as will be hereinafter referred to, and

trip-lever mounted in said loop and provided with the arm 17.

18 designates the inclined brace-bar, having its notched lower end engaged by the arm 17 of the trip-lever and held in such relation by the loop l5.

All the parts thus far described are of common and well-known construction, with the exception that instead of pivoting the upper end of the brace-bar 18 to the standard 5, as in the old machines, I pivot it at its upper end to the small angle-lever 19, f ulcrumed on said standard, which lever is by preference of vbifurcated or branched construction (see Fig. 3) and terminates at its upper end in a hook 20, connected by a chain 23 or its equivalent to the lever 11 forward of its fulcrum-point.

22 designates a locking-dog pivoted, preferably, to the pivot connecting brace-bar 18 and lever 19 and extending through the latter, said dog being provided with a tooth 22 to bear at its front or rear end against the rear or front edge of the standard 5, and thereby hold the pan in position for loading or for carrying to the dump. This dog has a relative sliding movement through lever 19, but is prevented from sliding clear through the same to an inoperative position by the laterally-projecting handle 22h at its free end.

In practice, assuming that the machine is in position to be loaded, it will be noticed that the pan is almost upon the ground in a horizontal position, and that it is locked in this position by the engagement ofthe triplever with the notched lower end of the bracebar 18, the upper end of the latter being secured immovably by the engagement of the front end of tooth 22a of dog 22. In this position the levers 1l and 19 stand about upright, with the chain hanging loosely between them. In such position the machine is loaded by the time it has traveled about nine feet of space, while the old machine must travel approximately thirty feet of space before it is loaded, consequently imposing more labor on the draft-animals and vconsuming more time in effecting this object. At the same IOO time it is subjected to greater strain, particularly because the pans in the old machines slant at a decided angle downward and forward. The reason that the old pan slants in this manner is that the upper end ofthe bracebar 1S is pivoted at a fixed point upon standard 5, while in the machine ofthe present application the rear end of the pan can be lowered a greater distance, because the upper end of the brace-bar is pivoted to a lever and can therefore be lowered. The interposition of this leverbetween the standard and said bracebar is one feature of my invention. Assuming now that the load is gathered, the driver upon the platform 8, after iirst disengaging dog 22 from standard 5, grasps and depresses the front or handle end of the lever 11 and engages the same with the pivoted foot-dog 10, which thus holds the pan elevated, as shown in Fig. 2, in which position it is conveyed to the dump. It will be noticed in this connection that as said lever is depressed and consequently through the medium of the connecting-chain 23 pulls lever 19 to the position shown in Fig. 2 the pivoted dog 22 is dragged over the upper end of the standard until its tooth clears the top and engages the front edge of the same, the weight of the loaded pan upon the brace-bar 18 obviously holding said tooth 22 tightly against the front edge of said standard as long as the pan remains in the described position, the dog being held reliably in this position by resting on top of the standard.

To dump the load, the driver trips the dog 10 with his foot in the customary manner and releases lever ll, which action is instantly followed by a downward movement on the part of the front end of the pan, and preferably before such movement ends by the front end of the pan striking the ground the dumpboss pulls upward upon the trip-lever and disengages it from the notched end of the brace-bar, thereby effecting an oscillatory movement of the pan, so that bythe time its front end strikes the ground the loop 15 is slipped upward upon the brace-bar 1 S to about the position shownin dotted lines,- Fig. 2, and the discharge of the earth from the pan has begun, which discharge is made continuous because the draft-auimals are moving forward all the time and therefore cause the pan to swing on its front end as a pivotl until it has assumed a vertical position and rests on its front end, with the loop 15 embracing the upper end of the brace-bar.

To restore the pan to operative position, the driver grasps and trips the dog 22 from engagement with the front edge of the standard, which causes the brace-bar 1S and lever 19 to resume the position shown in Fig. 1 and permits the pan by gravitative action to descend to the position shown in Fig. 1, the loop 15 sliding down upon the brace-bar until such movement is terminated by the rengagement of the trip-lever with the notch of said bracebar. This operation being accomplished at the proper time, the continued movement of the machine reloads the pan, and then the driver depresses lever 11 and causes it to again engage the foot-dog 10 to raise and hold the pan a suitable distance above the ground, and it will be noticed in this connection that this movement ot said lever results in raising the pan a greater distance above the ground than in the old machines,i`or thereason that the upper end of the brace-rod 1S is simultaneously elevated, where in the old machines the upper end of the rod remains stationary.

All subsequent operations of the machine are repetitions of those described.

From the above description it will be apparent that I have produced a machine embodying the features of advantage enumerated as desirable in the statement of invention, and it is to be understood that I reserve the right to make such changes in the detail form, oroportion, or arrangement of the parts as properly fall within the spirit and scope of the invention.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is-
