ROTARY SCRAPER.
SPECIFICATION forming part of Letters Patent No. 712,838, dated November 4, 1902. Application filed April 9, 1902. Serial No. 102,008. (No model-I T aZZ whont it may concern;
Be it known that I, RALPH HERRMAN Mc-;
CAUGHEY, a citizen of ,the United States, residing at Campbell, county of Santa Clara, State of California, haveinvented an Improvement in Rotary Scrapers; and I hereby declare the following to be a full, clear, and
exact description of the same.
My invention relates to improvements in dirt-scrapers. It is particularly intended for use in blocking up corners in orchards before irrigating. Its object is to provide a device which can be easily dumped and which will automatically right itself, allowing the operator always to retain hold of the handles.
It consists of a scoop or shovel adapted to slide along the surface of the ground, handles pivoted to lugs upon the sides of the scoop, projections on the rear of the latter, spring-actuated latch members engaging said projections, one of said latch members connected with a hand-lever upon one of the handles by which the latch may be released to allow the scoop to dump and the other of said latch members adapted to engage the scoop when the latter is again righted and hold it in proper relation to the handles.
It also comprises details of construction which will be more fully described hereinafter, having reference to the accompanying drawings, in which- Figure l is a rear elevation of my invention. Fig. 2 is a side elevation. Fig. 3 is a longitudinal section on the line a: 00, Fig. 1, showing the scraper in a dumping position.
A represents a scoop or shovel, and 2am metal arms united by the cross-piece 3 and pivoted to the shovel at 4. The handles 5 are secured to the arms 2.
The pivots 4 consist of perforated lugs bolted or riveted to the sides and centrally of the scoop. The eyes of the draft-bail 6 slip on over the lugs, and the parts are held in place by means of bolts '7.
The shovel is intended to revolvein dumping without the necessity of the operator releasing the handles. In order to maintain the shovel in horizontal position until such time as the operator is ready to dump the load, I have provided an upper and lower set of latch members upon the handles which are .on the shovel. bers consist of downwardly-extending arms adapted to engage corresponding projections The lower set of latch mem- 8, pivoted to the handles at 9, having their upper ends engaging the ends of a centrallysnpported spring-bar 10, while their lower ends have inwardly-extending projections 11, which are adapted to engage the under side of the cam-stops 12, secured at the corners of the shovel. This latch device prevents the rear end of the scoop from dropping. It is prevented from rising by means of the latchbar 13, whose arms 14 are likewise pivoted to the handles at 9, engaging the upper edges of the projections 15 on the rear side of the scoop. The latch is normally pressed into the path of these projections by means of a centrally-supported spring-bar 16, like unto bar 10, engaging the upper ends of the arms 14. The latch member 13 is connectedby means of a link 17 with a lever 18 on one of the handles disposed within convenient reach of the operator. The springs and-16 are held in a clamp 19, secured centrally of the cross-piece 3'of the handle-frame.
In operation the-loaded scraper is dumped by raising up on the handles and simultaneously pressing in on the hand-lever 18,which causes the latch 13 to disengage the projections 15, allowing the shovel to turn over as .the horse moves forward. The lever 18 is then released, so that the latch 13 will engage the stops when the scoop has finished its revolution. The arms 8 are pressed out of the way as the scoop swings again into horizontal position by means of the curved upper edges or cam-surfaces 20 of the stops 12. As the stops 15 strike the latch 13 the latch-arms 8 engage beneath the stops 12 and automatically lock the scoop'in position.
Having'thus described my invention,what I claim, and desire to secureby Letters-Patent, is
1. The combination in a scraper of a scoop or shovel, handles pivoted to the sides thereof and between which handles said scoop is revoluble, spring actuated latch members carried by said handles pivotally mounted between their ends and having their lower ends extending down in rear of the scoop, stops on said scoop engaging said lower ends of said latch members and means by which said latches may be released to allow the scoop to revolve.
2. The combination in a scraper, of a scoop or shovel, handles pivoted thereto, springpressed latch members on said handles, and pivotally mounted between their ends said members having their upper ends engaged by springs and their lower ends extending downwardly behind the scoop, stops upon the back of said scoop, said latch members engaging said stops to hold the scoop in horizontal position, a lever in connection with said handles and connections between said lever and one of said latch members whereby said latch may be released to allow the scoop to revolve.
3. The combination in a scraper, of a scoop or shovel, handles pivoted thereto, stops on said scoop and projecting rearward thereof, latch members pivoted on said handles and pivotally mounted between their ends having their upper ends extending above the handles and their lower ends extending below the handles and engaging said stops to prevent the scoop turning, centrally-supported transversely-extending spring members engaging the upper ends of said latch members whereby the latter are normally held in the path of said stops and means by which said members may be operated to allow the scoop to revolve.
4:. The combination in a scraper, of a scoop or shovel,having perforated lugs secured centrally of the sides thereof, handles and draftbails embracing said lugs, means for securing them thereon, a cross-piece connecting the handles rearward of the scoop, pivoted latch members on said handles,centrally-snpported spring-bars secured to said cross-piece and engaging the ends of said latch members, stops upon the scoop adapted to engage said latch members and lock the scoop in position, a lever pivoted to one of said handles and a link connecting said lever and one of said latch members whereby the latter is operated to release the scoop and allow it to revolve.
In witness whereof I have hereunto set my hand.
RALPH IIERRMAN MCCAUGIIEY.
