IMPROVEMENT IN KNIVES FOR REMOVING CORN FROM T'I--IE COB.
Specification forming part of Letters Patent No. 54,170, dated April 24, 1866.
To all whom it may concern:
Be it known that I, JOHN W. JONES, of Portland, in the county of Cumberland and State of Maine, have invented a new and useful Improvement in Knives for Removing Green Oorn from the Cob; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters ot' reference marked thereon. l.
Myinventiou consists ot' an adjustable gage for knives employed in removing green corn from thecob, and also in a steel gage for such knives.
Being extensively engaged in preserving green corn according to the process originally invented by Isaac Winslow and the several improvements thereon, l have found that the knife invented by Winslow, though a great The gage, not being adjustable upon the blade ot' the knife, is vfitted only to one size ot' kernels of corn, and it often happens with large kernels that two strokes are required to eut od the entire kernel, while with small kernels 'the gage does not prevent cutting oft' a portion of the cob. lVIoreover, the gage being soldered to the blade of the knife, it is ditlicult to grind or sharpen the latter. ln case the tin gage is corroded by rust or otherwise soiled it is not so easily cleaned as my gage, which may be removed and ground.
The object. ot' my invention or improvements is to remedy the above-mentioned defects and produce a superior knife for cutting green corn from the cob.
In the accompanying drawings, Figurel represents a front view ot'a knife with mymprovements attached. Fig. 2 is a rear View of the same. Fig. 3 is a view of the back of the knife, showing the space between the knife and gage.
In the manufacture ot my improved knives the blade is curved more or less laterally, as
i seen at A in Fig. 3, in order to work better against the cob. This curvature may be in either direction7 so as to suit either righthanded or left-handed workmen.
The gage B, Figs. l, 2, 3, is made of steel and iinished up with care, like the blade ot' the knife. This gage is attached to the blade of the knife by means of thumb-screws C working in female screws eut in the thick parts or ends ot' the knife-blade. The ends of the gage are provided with slots b, in order to allow the gage to slide upon the thumb-screws when the latter are loosened, thus rendering it easily adjustable t'or the purpose ot' cutting' of larger or smaller kernels of corn or cleaning the eob of the parts of kernels already cut. Small Washers, l), are employed as bearings Aunder the heads ot' the thumb-screws.
By withdrawing the thumb-screws the gage may be completelyremoved from .the blade ot' the knife, and then the knife can be easily ground like any other knife; and the gage itY self, when thus removed, may be ground on both sides or easily cleaned from rust or other soiling from use or neglect. Thus the gage is much better on account of being removable.
l do not broadly claim a curved knife provided wii-h a gage for cutting' green corn, but confine my invention to the adjustability of the gage and 'to making the same of steel as an improvementover the rude tin gage known prior to my invention.
Having thus fully described my invention, what l claim, and desire to secure by Letters Patent of the United Sta-tes, is-
The above-described knife provided with a broad adjustable gage, substantially as set forth.
J. W. JONES.
