JAMES I4. LATTURE, OF PORTLAND, OREGON, ASSIGNOR TO THE BURCH PLOW WORKS COMPANY, OF CRESTLINE, OHIO, A CORPORATION OF OHIO.

sworn: srnmnnn.

Application filed July 12, 1921. Serial, No. 484,178.

To all whom it may concern Be it known that I, JAMES L. LA'I'IURE, citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Stone Spreaders, of which the following is a specification.

'This invention relates to an improved stones reader of the character disclosed in Patent 0. 1,281,141, issued to.W. J. Coultas, October 8, 1918, and has as one of its principal objects to provide a device which may be employed for unloading stone from a motor truck on a pike road and distributing the stone to one side of the road for building the shoulder to the pike.

The invention has as a further object to provide a device employing a hopper for receiving the stone discharged fromt etruck and wherein spreading wings will be provided in conjunction with the hopper for spreading the stone issuing from the hopper toward one side of the pike.

A further object of the invention is to provide a device wherein the inclination of the spreading win with respect to the hopper may be readi adjusted.

And the invention has as a still further object to provide a device wherein one of the wings may be adjustably positioned in an lar relation to the other of said wings.

ther and incidental objects will appear hereinafter.

In the drawings:

Figure 1 is a perspective view of the spreader,

Figure 2 is an enlarged fra entary plan view showing the connection between the inner and outer wings employed.

Figure 3 is an enlarged elevation showingthe mounting of the inner win and i re 4 is a fragmentary elevation showin%t e mounting of the outer wing.

eferrin now more particularly to the drawings, employ a hopper 10 providing end walls joined by front and rear walls, the front wall being inclined with respect to the rear wall and diverging therefrom toward the open top of the hopper. The hopper is also open at the bottom thereof and adjustably mounted on the rear wall of said hopper 1s a gate 11. The end walls carry shoes 12 and secured to the front wall are plates 13 to which are connected chains 15 by which the hopper may be secured to a truck to ride at the rear thereof upon the shoes 12 in such position that the truck may discharge into the hopper. Stone thus deposited in the hopper will be discharged beneath the gate 11 to be distributed upon the roadway. Since this hop er is disclosed in detail in the patent of oultas previously identified, it will not be further described herein, the present improvements relating particularly to a means for directing the stone discharge from the hopper to one side of the roadway for forming a shoulder to a pike.

Secured against the rear wall of the hopper at one end thereof is, as shown in Fi ure 3, a top bracket 16 and alining with the bracket are mating bottom brackets 17 and 18 respectively having bolted connection with the adjacent end wall of the hopper; Fittin through these brackets is a vertically isposed hinge rod 19 upon which is fixed a collar 20 coacting with the bracket 16 while other collars 21 are arranged upon the rod to coact with the bracket 17 cooperating with the collar 20 for locking the rod against longitudinal movement. Swingingly connected at its inner end with the rod is a main inner spreadin wing 22 which may be formed of suitab e sheet metal braced at its upper and lower mar ins by angle plates 23 and overlying these p ates at the inner end of the wing are hinge straps 24 through which are engaged bolts 25 connecting the straps with the wing. At their outer ends, these straps are provided with hinge loops 26 surrounding the rod, the loop of the lowermost strap being arranged to engage the rod between the brackets 17 and 18 and mounted upon the rod above and below the loop of the uppermost bracket are collars 27 securing the wing a ainst vertical movement. However, as wil be observed, the collars may be adjustably positioned upon the rod so that the wing may, accordingly, be adjusted vertically with respect to the rod.

Mounted upon the free end of the wing 22 at its outer side is a medially arranged angle bracket having angularly disposed

portions

28 and 29, the portion 29 of the bracket be,- ing secured at its free end by a U-ibolt 30 projecting at the inner side of the wing at its adjacent end. Bolted to the portion 28 is a bearing 31 and fitting through said bearlower end of which is fixed a shoe 33 supporting the wing 22 at its outer end, the post being held against upward movement through the bearing by an adjustable collar 33'. Bolted to the portion 29 of the angle bracket is a second bearing 34 and fitting through said bearing is a vertically disposed hinge rod 35 to which is swingingly connected an outer spreading wing 36. TlllS spreading wing may also be formed of sheet metal, being reinforced at its upper and lower mar ins by angle plates 37, and, as shown in igure 1, the outer wing is somewhat shorter than the maininner wing. Overlying the plates 37 at the inner end of the wing 36 are hinge straps 38 in which are formed slots 39 and extending through said slots are bolts 40 'adjustably connecting the straps with the Wing. At their outer ends, the straps are provided with hinge loops 41 embracing the rod 35, the loop of the uppermost strap coacting with" the upper end of the bearing 34, and interposed between the loop of the lowermost strap and longitudinal movement.

the lower end of the bearing is an adjustable collar 42 upon the rod locking the rod against Extending transversely between the angle plates 37 at the outer end of the win is a reinforcing plate 43 and extending t rough the wing and through said plate is a U-bolt 44 projecting at the inner sideof the wing. Secured upon the hopper to overlie the inner ends of the plates 13 are plates 45 projecting beyond the ends of the hopper 10 and mounted on the plates 45 are U-bolts 46. Extending between the U-bolt 46 at the adjacent end of the hopper and the U-bolt 30-at the outer end of the wing 22 is a chain 47 equipped at its ends with hooks, the end portions of the chain being passed through said U-bolts and the hooks engaged in intermediate links of the chain. s will be seen, this construction provides an arrangement whereby the effective length of the chain may be readily varied for adj ustably varying'the a larity of the wing 22 with respect to thd i opper, the chain ty' the wing at its free end to extend oblique y with respect to the hopper at the rear thereof. Secured at one end to the U-bolt 44 of the wing 36 is a chain 48, the free end of which is provided with a hook engaged with the chain 47 and adapted to be adj ustably positioned tlierealong. The chain 48 will, therefore, tie the free end of the wing 36 so that this wing will, in effect, form a continuation of the wing 22 and by positioning the hook of the chain 48 along the chain 47, the angularity of the wing 36 with respect to the wing 22 may be readily varied.

As will now be understood in view of the preceding description, as stone is discharged into the hopper 10 from a truck and the hopper is drawn forwardly,the

wings

22 and 36 will direct the stone as it issues from beneat-h the gate 11 of the hopper laterally to one side of the pike so as to form a shoulder thereon. Proper s reading of the stone will thus be accomplis ed coincident with the dump-ing thereof and by providing individual adjustments for the

wings

22 and 36 whereby the angularity of the wings with respect to each other as well as with respect to the hopper may be readily varied, the lateral distribution of the stone may be easily controlled.

Having thus described the invention, what is claimed as new is:

1. A device of the character described including a hopper provided with a discharge opening, and a spreading wing connected with the hopper and inclined in a direction acrosssaid opening from one end thereof for distributing all of the material issuing from said opening laterally in one direction with respect to the hopper.
