WHEELED SCRAPER.

SPECIFICATION forming part of Letters Patent No. 364,493, dated June 7. 1887,

Application filed Juno 5', 1886. Serial No. 204,468.

(No model.)

To aZZ whom/it may concern:

Be it known thatl, PATRICK DEEVY, of Dudley, in the county of WVapello and State of Iowa, have invented a new and Improved Wheeled Scraper, of which the following is a full, clear, and exact description.

My present invention relates to the construction of that class of scraper illustrated, described, and claimed in my application, No. 167,897, filed on the 6th day of June, 1885; and the invention consists of certain improvements upon the construction illustrated in said application, which improvements will be hereinafter more fully described, and specifically pointed out in the claims.

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

Figure 1 is aplan view of my improved form of scraper, certain portions being shown in section. Fig. 2 is a side view of the scraper, representing the parts as they appear when the bowl is depressed to the position it assumes when being filled, the wheel upon the side of the scraper illustrated being, however, removed. Fig. 3 is aside view of the scraper, illustrating the parts as they appear after the bowl has been raised to a position so that the load gathered while in the position in which the parts are illustrated in Fig. 2 may be removed to the spot where it is desired to dump the load; and Fig. 4 is a side View of the scraper, the parts being shown in the position they assume after the load has been dumped, this being the position to which the bowlis moved when it is desired to move the unloaded scraper from place to place.

The scraper-bowl 100 is made in the general form of a scoop, the rear of the bowl being, however, stiffened and strengthened by a malleableiron casting, 10, that is riveted to place about the rear inner and upper edge of the bowl, as best shown in Fig. 1. To the sides of the bowl there are riveted suspending arms 11, the upper ends of which are formed with sockets 12, through which the horizontal central portion, 13, of the axle passes, collars 14 being formed on said axle in position so as to properly space and prevent any side movement of the sockets 12 of the suspending arms 11. Just outside of the sockets 12 there are secured the crank-arms of the axle, sa d crank-arms being formed with sockets at the1r upper end, within which the ends of the axle 13 are inserted, the parts being keyed together as shown in the drawings.

The crank-arms 15 carry the journals 16, upon which the wheels are mounted. The journals 16, upon which, as just stated, the wheels 20 are mounted, carry hoods 17, that are keyed to the inner ends of the journals and project outward over the hubs 18 of the said wheels 20, serving to protect the journals from sand, dirt, or grit of any kind.

Upon each side of the bowl 100 I secure an outward] y-extending bracket, 19, to which the rear ends of the draw-bars 21 are pivotally connected through the medium of bolts 22, the brackets 19 being so formed that the draw-bars will be at some distance from the sides of the scraper-bowl. The draw-bars are of peculiar form, being provided with a rearwardly-extending lug or ear, 23, by means of which pivotal connection with the brackets 19 1s established, said lug or ear extending backward from the upper end of a substantially vert1cal portion, 24. From the lower end of the portion 24: the draw-bars curve forward and then upward and forward, this upward and forward extending portion being riveted or otherwise secured to the main crossbar 25, against the forward face of which the pole 26 abuts, the stock of said pole entering between angle-irons 27, that are secured to the crossbar 25, as best shown in Fig. 1.

Just in front of the cross-bar the draw bars 2i extend inward until they strike the side of the pole 26, and at that point they are bent forward, and their ends 28 so bent forward are firmly bolted to the pole.

At the rear of the scraper-bowl there is arranged the main operating-lever 30, said lever being provided with two outwardly-branching arms, 31, which extend forward a short distance in diagonal lines as they leave the lever 30, and then extend outward at right angles to the lever in the same horizontal plane, to

be bent so asto extend forward in parallel lines at 32, said forward parallel extending portions being shown at 36. To the arms 31 there is secured a bar, 33, formed with two forwardly and downwardly extending arms, 34, the lower ends of which are pivotally secured to the sides of the bowl 100 by brackets 35. As best shown in Fig. 1, the arms 34 are arranged so that between their outer faces and the forwardly-extending portion 36 of the arms 31 there is a space, and in this space so formed there are arranged connecting-rods 37, said rods being pivotall y mounted through the medium of bolts 38.

The forward ends of the connecting-rods 37 are pivotally connected to rearwardly-extending and slotted lugs 39, formed upon the crankarms 15, the forward ends of the connectingrods entering the slot formed in said lug 39.

From the construction just described it will be seen that the'scraper-bowl is hung so as to swing upon the horizontal portion of the axle of the scraper, and it will also be seen that the angle at which the bowl hangs depends upon the length of the connectingrods 37, and consequently in order that this angle may be varied I have formed said connecting-rods with anumber of holes, 2, through anyone of which the bolts 38 may be passed, in order that the bowl may be adjusted as required.

Projecting to the rear of the scraper-bowl there are handles 40, said handles being riveted to the sides of the bowl, and to the center of the rear end of the bowl there is pivotally connected a catch, 41, that is provided with a rearwardly-extending handle, 42, said catch being formed with an upper inclined face, 43, against which the central portion of the cross bar 33 strikes when the lever 30 is being thrown to the position in which it is shown in Fig. 3. The throw of the lever 30 is limited byastop, 5, which projects to the rear from the scraperbowl 100. Upon being struck the catch will be thrown toward the bowl, permitting the bar 33 to pass, and after the bar is below the tooth of the catch the handle 42 will act to throw the catch to the rear, so that it will engage with the upper face of the said bar 33.

In order that the bowl may be held in a fixed position when lowered to the position in which it is shown in Fig. 2, I have provided such an attachment as will now be specifically described. To each side of thebowl 100, and near the forward edge of said bowl, there is rigidly secured a bracket, 45, which serves as the supportfor a pivotally-mounted lever, 46, to one end of which there is secured an outwardly-projecting pin, 47. The opposite and lower ends of the levers 46 are connected bylinks 49 to the lower ends of lugs 50, formed upon the arms 34 of the bar 33.

In connection with the pin-carrying levers 46 I arrange oscillating strips 52, in the rear ends of which there are formed flaring bellshaped slots 53. The strips 52 are made integral with practically vertical strips 54, that fit close against the inner faces of the drawbars 21, the upper end of each strip being bent to form cars 55, which overlap the upper edges of the said draw-bars. The lower ends of the strips 54 are bent outward beneath the draw,

bars 21, to form lugs or cars 56, and in these lugs or cars 56 I make threaded sockets, in which there are mounted adj usting-screws 57.

Referring now to Fig. 2, it will be seen that as the bowl 100-is lowered the lugs 50 will be thrown back, and, drawing upon the connecting rods or links 49, will throw the upper ends of the levers 46 forward, so that their pins 47 will enter the bell-shaped slots 53, formed 1n the oscillating strips 52, and consequently when the parts are in the position shown in the figure referred to-that is, when the bowl is being loaded all possibility of the accidental dumping of the bowl will be avoided; also, a certain amount of play will be permitted,,owing to the fact that thestrips 52 are free to oscillate within certain limits.

When it is .necessary to transport the scraper from place to place, itis desirable that the bowl should be moved to a position in which it will be held above the ground, so as not to require any particular attention from the driver; and to meet these requirements I have provided a catch, 60, thatis pivotally mounted in a standard, 61, and normally held in the positlon 1n which it is shown in the "drawings by the ac tion of a spring, 62, one end of which is r1gidly fixed to the catch-arm, while the other presses against the inner upper face of the recess, within which the catch is pivotally mounted. From its catch'tooth 63 the catch projects upward in a diagonal line to the rear, thus forming a handle, 64, and'at the same time providingfor the automatic lift-ing of the catch when the bowl is to be thrown to the position in which it is shown in Fig. 4, for as the bowl is raised to the position indicated one of the arms 31 will strike against the inclined face of the handle 64, and the catch will be raised against the tension of the spring 62 until its catch-tooth 63 has been brought into engagement with the flange 3 of the stop or projection 5, that is secured to the rear end of the scraper-bowl, as above stated.

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

1. The combination, with a wheeled scraper having the crank-axle, and the pivoted bowl provided with locking-levers at or near the forward ends of itssides, of the draw-bars pivotally connected with the bowl and having locking strips constructed to be engaged by the said locking-levers, and the manipulatinglever connected to the bowl, links connecting the said lever and the crank-axle and also connecting said lever and the locking-levers, substantially as set forth.

2. In a wheeled scraper, the combination, with a crank-axle,of asuspended scraper-bowl, a manipulating-lever, the ends of which are pivotally connected to the scraper-bowl, and a link formed with a number of apertures and arranged to connect the lever and the axle, sub stantially as described.
