SCOOP CLEANER.
Application filed March 26, 1925. Serial No. 18,483.
may be scraped to remove the contents there-- of, and prevent the earth dug by the scoops from adhering to the scoops.
Another important object of the invention is to provide a movable scraper Whlch will be actuated automatically by the movements of the links of the chain supporting the scoops, eliminating the necessity of providing pivoted arms or the like for operating the scraper.
With the foregoing and other objects 1n view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.
Referring to the drawing:
Figure 1 a longitudinal sectlonal view 11- lustrating a length or chain carrying scoops and scrapers constructed in accordance with the invention. 7
Figure 2 is an enlarged plan view of a scoop and scraper.
Figure 3 is a modified form of scoop cleaner.
Referring to the drawing in detail, the reference character 5 indicates links of a supporting chain to which the scoops 6 are secured.
The scoops are of the usual construction and embody digging prongs 7 which are secured to the forward edges of the scoops in the well known manner.
The scrapers forming an important feature of the invention include bars curved intermediate their ends to provide a curved scraping surface 8 conforming to the curvature of the scoops in whlch they operate.
By fo ming the scrapers, in a manner as described, arms 9 are provided which arms are relatively long and are armed with 7 chain openings arranged in spaced relation with the ends thereof, which openings accommodate the bolts 10, while the ends of the arms 9 are formed with openings to accommodate the bolts 11 whereby the scraper is securely held to the links of the chain.
Itmight be further stated that scoops as shown and described, when supported on endless chains operate over suitable sprockets indicated at passes over the sprocket, the arms of 12, to the end that as the the scraper move downwardly with one link of the chain, moving the scraping portion thereof over the inner surface of the scoop supported adjacent to the link supporting the arms. of the scraper, the forward edge thereof is beveled as at 13 to cut into the material picked up by the scoop.
In the form of the invention as illustrated by Figure 3 of the drawing, the scraper includes a pair of scraping blades 14 that are pivotally supported adjacent to the scoop 15, the pivot point being indicatedat 16. formed integral with the blades and extends to a position beyond the chain supporting the scraper so that the arm lies in a position to engage the bar 18 supported under the chain to the end that as the arm moves over the bar 18, the scrapers are operated through the scoop to clean the scoop.
Associated with the armof each scraper is a coiled spring 19 which is adapted to return the scraper to its initial position after it has been moved through the scoop.
From the foregoing it will be obvious that the scoops indicated at A and which will be filled with material and that as the described, scoops secured to the scrapers including elem An arm indicated at 17 is Q p I 1,588,638
