UNITED STATES PATENT EEicE.
JOHN E. ROBERTSON, OF CONCORD, NEIV HAMPSHIRE.
lCE-SCRAPER.
SPECIFICATION forming part of Letters Patent No. 408,853, dated August 13, 1889.
Application filed January '7, 1889. Serial No. 295,595. (No model.)
To all whom it may concern.-
Be it known that 1, JOHN E. ROBERTSON, a citizen of the United States, residing at Concord, in the county of Merrimac and State of New Hampshire, have invented certain new and useful Improvements in Ice-Scrapers, of which the following is a specification.
The object of this invention is to provide an ice-scraper of such improved construction that the work ordinarily requiring two drafthorses may be easily accomplished with a single horse.
The improvements will be fully set forth in the following specification and claim, and clearly illustrated in the accompanying drawings, forming an inseparable part thereof, of which- Figure 1 is a broken view of a runner, showing one of my improved axle-bearings in cross-section. Fig. 2 is a cross-section of a runner taken through its axle-bearing and showing the axle in elevation therein, the latter being attached to one end of my improved scraper. Fig. 3 is a longitudinal sectional view of the machine complete, showing in dotted lines the position assumed by the scraper and its connections when dumping. Fig. 4 is a longitudinal half plan of the machine.
Similar letters indicate corresponding parts.
The scraper A may be formed of plank, having, preferably, a metallic knife B, secured by bolts 1) to one side and projecting below its bottom edge.
A frame consisting of the bars 0 C and a plank D extends rearward from the scraper, its forward end being secured to said scraper in the proper position to cause the said scraper to assume a vertical position, or nearly so, when the rear end of said frame shall rest upon the ice. Upon the front side of the scraper suitable eyebolts E are provided, to which the thills F, carrying an ordinary whiffletree f, are connected.
The bars C O should be provided with iron or steel shoes 0 and with a brace c, bolted to the scraper; and, if desired, the shoe-irons 0 may extend far enough forward to serve the purpose of the braces c, as shown in Fig. 3.
The scraper A is provided with axles G,
which may be conveniently attached, one at either end, by means of an integral yoke g, which straddles said scraper and through which bolts g are passed. These axles G are mounted in vertically elongated boxes H, which are set in ordinary sled-runners I, thus affording to the scraper A both a vertical as well as rotative motion.
In scraping a pond it is customary to drive into the snow or sleet in a circuitous course, and by reason of the thills being attached directly to the scraper and the said scraper be ing capable of a vertical movement independent of the runners, if at any time said scraper should be accumulating a greater quantity of snow or sleet ahead of it than a horse can conveniently pull off the pond, the scraper A will rise a little, taking off a thinner layer and leaving the rest or what remains to be taken at a subsequent trip.
When the machine is in use, the driver may stand upon the footplank D of the extension-frame, and thus hold the scraper to its work until that point has been reached at which he is to deposit the scrapings, when he alights, and the scraper immediatelyassumes a horizontal position, as shown in dotted lines in Fig. 3, and passes over the pile of scrapings, thus avoiding the necessity of backing the horse off and turning around.
The runners are provided with iron or steel shoes 1', and in theirt-op openings are formed, in which the axle-bearin gs II are inserted. In the drawings the latter are provided with flanges h on their sides, which lap over the sides of the runner and hold them firmly against any lateral play, while a cap-iron i (which may be simply an extension of the shoes 2', as shown) is placed upon their top and extends far enough forward and back to receive bolts h, which secure said bearings to said runner. A collar G, of larger diameter than the elongated axle bearing H, mounted upon a reduced threaded portion g of the axle G, and the nut g fitted to the said threaded portion 9 hold either runner I in its proper position, and the chains J, connecting the forward end of either runner with the thills, help to steady the said runners.
Having described my improvements, what I elainnand desire 10 secure byLeivters Patent, 0f the ice when said scraper assumes its nor- 1s inal position, substantially as and for the pn r- In an iee-seraper, a pair of sled-runners, an pose specified. interposing Seraper mounted at right angles Intestimonywhereof I allix inysignaiure in 5 therewith and capable of vertical and eseilpresence of two WlLUCHSQS.
