O laims.

This invention relates generally to spreaders of the character illustrated in my- Patent No.

1,502,007 g'rantedJuly22, 1924 on a stone distribtain improvements in the de'tails'of construction and certain improvements whereby the spreader;

and at their rear ends are bent downward asjat may be used for spreading asphalt or stone and whereby the asphalt maybe distributed or spread:

bars 21 are'pivoted so that they may be raised or "lowered and thus raise or lower the strike-off plate 23. where thi s strike oifplate is intended to be-operate'd by'hand-asinstone spreading, an

and raked to prepare the asphalt for rolling.

A further object in this connection is to provide simple means whereby the strike ofi blade may be arranged either for -adjustnientby hand \orfor adjustment by means of screws, the"latter means nbeing particularly designed for use, 1-151 where asphalt is being spread which requires a fine adjustmentbf the strilg'cofi' more or less blade;

A furtherobject is to proyide'means whereby the rake maybe vertically adjusted and whereby the teeth of the rake may be renewed'from time u t time when unduly 3 A further object is to provide'means whereby the strike-off blade'maybe adjusted a'little higher at one side than at the other. a V v 25 Other objects will appear in'the course of the followingdescription. My invention isillustrated in ing drawings; wherein: j

Figure l is an end asphalt spreaderconstructed in accordancewith my invention; p p Figure 2 is "a fragmentary rear; elevation" of the asphalt spreaderbut with the asphalt r'ake removed;

Figure 3 is' asectio'n onthe line 3 -13 of Iiig- I Figure i is a section on the line"4 4:of Fig- I r l a in Figure 5', are the angle irons 29 and 29 which the line 55 of Figure 2;

' In the drawings, 10 designates a hopper-shaped container made of sheet metal having a downwardly and rearwardly convergentfront wall 11 and a vertically disposed rear wall 12 with end walls 13, the body of the container-beingbraced by the angle iron frames 14. Thebottom of the hopper is open and'attached to the hopper at its ends are the stop-off plates 15. r

i The hopper is operatiyely supported upon the runners'16 :which'aremadeof' angle iron or channel iron attached at their upper ends to the upper end of the hopper infront' thereof and extending downward and rearward" and thenhorizontally 36 at'its extremities. This handle is keyed upon the shank of: the screw and is-"heldzin place by; a 110 beneath the hopper." Mounted uponsthese run- 5 nersare the downwardly and forwardly extending elevation of afsto ne' and ;Mounted upon brackets 20 attached to the front wall of the hoppermore or less adjacent itsupper end are the-"draw bars 21 which extend rearward 22 to support astrike-ofi blade 23." These drawar na -platen is mounted at each end of the hopper, this plate being provided'with apertures 25 and each draw bar 21 'beingprpvided with a latch' designated generally 26' which includes a pin adapted to'be insertedin any one of the apertures'25 to hold the draw bar-s21 and the strikeoff blade at any desiredheight'; This issubstantially the same constriiction as isillustratedirr'rny g -z Patent 1,502,007., Preferably, howeveri'the arc'uate guide plate 24-willextend fromtop tobottom of the hopper so' as to give 'a' veryflargera ge-gor adjustment to the strike-oil blade whereas "a ien Q 'ativelyashort range of adjustment :was 'provided for in my Patent f1 ,502,007. It will be understood that the pin '26 is-adapted to be entirely removed "from'thelever or shifted out of engagement'with any of the-apertures 25 undercircunistances'when o "tha' lt i e-b blad i .iin v e t be lowered by'means of screws a's'will bef-l'ater stated. The strike-off blade 23 has weldedto'itat each end a reinforcing plate 27 and is also reinforced 'bya longitudinally extending angle 28; Attached tothereinforcing plate 27 and the strike-61f blade 23 by a bolt 30 which extends through thereinforcing plate and the strike-off bladek- 'as shown together'form a channel. Theseangle irons29 and 29 are formed with {apertures*fonengage-i 32 which is interiorly screw threa'ded. Thereare 14100 7 two of these housings 31' disposed at opposite'ends of th'e strike-off blade-and pivotally connectedto theistrike ofi blade by'means' ofthe" trunnions 30, as previously stated, and c'oacting with these housings are the screws '33f- The' upper ends of- "these'screwspass through collars 34'and at their upper ends; each screw 33 is provided-with a de-' tachable handle'35 formed with rotatable zknobs l screws mounted in said elements and extending through the nuts whereby the rake plate may be at their forward ends upon'the hopper and. at

their rear ends operatively connected to the strike-off blade, a rake plate operatively mountedupon the strike-off blade for vertical movement and having depending teeth, and means carried by the strike-off blade whereby the rake plate may be vertically adjusted.

3. A spreader including a downwardly discharging hopper, road engaging supports therefor, a strike-off blade disposed behind the hopper, means operatively connecting the strike-off blade to the hopper permitting vertical movement of the strike-off blade, opposed angle irons at each end of the strike-01f blade and having, flanges overlapping each other, the-outwardly projecting flanges of the angle irons having trunnion openings,- a bolt connecting both of said an- .gle irons to the strike-off blade, and screws at each end of the blade detachably engaged with the hopper, internally threaded housings with which the screws engage and having trunnions engaging said openings in the angle irons.

4. In an asphalt spreader, a downwardly discharging hopper, a strike-cit blade disposed behind the hopper, means mounted on the hopper for vertically adjusting the strike-01f blade relative to the hopper, a rake operatively mounted upon the rear face of the strike-oil blade for vertical adjustment and having depending teeth, and means carried upon the strike-off blade whereby the rake may be vertically adjusted.

5. In an asphalt spreader, a downwardly discharging hopper, road engaging supports therefor disposed below the lower end of the hopper, a strike-off blade disposed behind the hopper and normally below the lower endof the hopper,

means on the hopper for supporting the strikeoff blade, means on the hopper for vertically adjusting the strike-off blade, the strike-01f blade adjacent the opposite ends having a pair of radially projecting flanges having trunnion openings,

vertically disposed lifting screws mounted at their upper ends operatively upon the hopper, and internally threaded housings with which said lifting screws engagehaving trunnions engaging in said openings in the rearwardly projecting flanges.

10. In an asphalt'spreader, a downwardly discharging hopper, a strike-off blade disposed behind the hopper and operativelycarried thereby, and a rake operatively mounted upon the rear face of the strike-off blade and having depending'teeth.

11. In an asphalt spreader, a downwardly discharging hopper, a strike-01f blade disposed behind the hopper, means mounted in the hopper for vertically adjusting the strike-off blade relative to the hopper, and a rake'operatively mounted upon the rear face of the strike-off blade and having depending teeth.

12. An asphalt spreader including a road enblade operatively carried upon said structure but rearward of the hopper, the blade being vertically adjustable relative to the bottom of the hopper, and a'rake mounted rearward of the strike-off blade.

13. 'In an asphalt spreader, a supporting structure including ground engaging runners, an openbottomed hopper mounted upon said runners, a strike-off blade pivotally mounted upon said structureand disposed rearward of the hopper, means for vertically adjusting the strike-off blade relative to the bottom of the hopper, and a rake operatively carried upon the strike off blade and adjustable therewith and having depending teeth.
