LEONARD BAILEY, OF HARTFORD, CONNECTICUT.
IMPROVEMENT IN BOX-SCRAPERS.
_________________
Specification forming part of Letters Patent No. 182,881, dated October 3, 1876; application filed September 13, 1876.
_________________
To all whom it may concern:
Be it known that I, LEONARD BAILEY, of Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements pertaining to a Box-Scraper, of which the following is a specification, reference being had to the accompanying drawings, where —
Figure 1 is a side view. Fig. 2 is a top view. Fig. 3 is a bottom view. Fig. 4 is a top view, chisel removed. Fig. 5 is a central section on plane x x, Fig. 2, chisel removed.
The letter a denotes a forked handle, whereby to move the scraper back and forth. b denotes a rod, which is at once a pivot-bar for head c and a front rest for chisel d. The back side of the pivoted head c is obliqued, to form a bed for the chisel, which chisel is held in place by thumb-screw e running up through the bed elongation c’ from the back side, and bearing against the back side of the chisel.
The throat f may be made larger or smaller, and the out of the chisel correspondingly increased or decreased by manipulation of the guard or gage i, pivoted by its side arms i1 on the rod b, given a closing tendency by the spring-bar i2, and opened against this tendency by the thumb-screw g.
The features of invention, specified in the first two clauses of the following claim, are applicable as well to spokeshaves as to box-scrapers.
I claim as my invention —
1. In combination, head c, having bed elongation c’, chisel d, front rest b, and thumb-screw e passing through the bed elongation and pressing on the back side of the chisel, all substantially as shown and described.
2. In combination, bar b, head c, chisel d, guard or gage i pivoted on bar b, spring-bar i2, and screw g, all substantially as shown and described.
3. In combination, forked handle a, bar b, serving as pivot for head c and front rest for chisel d, pivoted head c having elongation c’, and screw e, all substantially as shown and described.
LEONARD BAILEY.
