This invention relates to a scraperblade mounting and more partlcularly to spring means for supporting the scraper blade 1n ro er relationshio to its su ortin means.
5 The instant application is a division of my patent for a road scraper, allowed March 22, 1932, No. 1,850,341. r
Gne advantage of the present invention resides in the fact thatthe coiled spring is cated apart from either the blade or its sup- Like numbers refer to like parts throughout the several views.
In the drawing numeral 10 indicates the supporting beam, this beam having hangers 11 depending therefrom. These hangers revoiubly carry the rock shaft 12, the mechanism for turning the rock shaft 12 being omitted.
The rock shaft 12 has a block 13 positioned adjacent thereto and a second block 14 fixed snugly against the block 13, these blocks having their adjacent faces recessed to receive the upper portion 20 of the coiled spring 21, the blocks 13 and 14 being detachably secured to the rock shaft 12 by means of the bolts 15.
The spring 21 consists of a U-shaped portion 22, see Fig. 2, which has either arm thereof coiled for a short distance and then continued in the portions 20, these portions 20, as previously described, being detachably held to the rock shaft 12. A clamping member 23 extends across the U-shaped portions 22 and holds the spring to the scraper blade 24.
f 5-3 Tie scraper blade 24, as indicated by the porting shaft whereby the springs may be easily installed or replaced In ts operative y The springs 21 provide a yieldable mounting for the scraper blade 24 and are quickly and easily installed by proper manipulation of the clamps holding them in place. The
substance against the scraper blade 24 and coil slightly due to this pressure thus preventing breaking of parts due to rigidity but et allowing only a very slight movement of the blade from its position.
I claim:
1. In a scraper structure, a rockshaft, a
scraper blade disposed substantially parallel to and spaced from the rock shaft, a spring member attached at one end to said rock shaft, said spring member having a spring coil therein intermediate its ends, the opposite end portion of said spring member lying at one side of the rock shaft, a block having a concaved sidefitting against the rock shaft, a second block lying against the first block between which blocks said end portion of the spring member is adapted to be located, and means for detachably clamping the blocks together against said end portion of the spring member and against each other and detachably securing them to the shaft.
2. In a device adapted to scrape roads or the like, a supporting means, a blade spaced a short distance from said supporting means and connecting means between the said supporting means and the said blade, said connecting means including a cylindrically shaped coil spring, said spring being located in spaced relationship to the said supporting means and abutting against said blade for the purpose described.
3. In a construction of the class described,
a spring arm member between the scraper blade and the rock shaft, said spring arm member comprising a length of spring rod bent to form a coil intermediate its ends, said ends being adjustably fastened to the scraper blade and the rock shaft for the purposes described.
4. In a device adapted to scrape roads or the like, a supporting means, a blade spaced a short distance from said supporting means and connecting means between the said supporting means and the said blade, said connecting means including a cylindricall-y shaped coil spring, said spring being located in spaced relationship to the said supporting means, said connecting means including an adjustable length connection for the purpose described. i In testimony whereof I affix my signature.
GEORGE E. DEAN.
