SPECIFICATION forming part of Letters Patent N0. 322.755, dated July 21, 1885. Application fnea Miu-eh 14,1885. (Model.)
To all whom it may concern..-
Beit known that I, ALFRED S. SEAMAN, a citizen of the United States, residing at Frackville, in the county of Schuylkill and State of Pennsylvania, have invented certain new and useful Improvements in Oil-Cloth Knives; and I do declare the following` to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to inake and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which forni a part of this specification.
Figure l of the drawings is a representation of this invention, and is a perspective view. Fig. 2 is a section taken across the handle. Fig. 3 is a side view.
'This invention has relation to knives for cutting oil-cloth; and it consists in the construction aud novel arrangement of devices, all as hereinafter set forth, and pointed out in the appended claims.
The object of this invention is to provide a knife of special construction which is designed to be used in cutting forward or push- .ing the knife through the cloth, a mode of cutting which is often very desirable, especially in following an indicating-line with precision.
In the accompanying drawings, the letter A designates the handle `of the knife, and B the blade. The latter is made with the tang portion C, which is preferably offset or without the line of prolongation of the upper edge, d, of the blade, being connected thereto by a neck portion, e. The lower edge, f, of the blade is beveled in front toward the lower guard-lug, g, of the cutting-edge. The cuttingedge h is at the front or point portion of the blade, being obliquely transverse with referthe cutting-edge h, is formed the upper guardlug, k, which serves to prevent the oil-cloth from slipping upward from the cutting-edge.
The lower guard-lug, g, is at the lower end of the cutting-edge, and projects forward therefrom. It serves to guard the cutting edge below, so that one sheet of oil-cloth can be cut while lying above another without danger of injury to the latter. dull, and the lug k is set back somewhat with reference to the lug g.
The lugs g and k, and especially the latter, may be pointed for convenience in entering the knife through the oil-cloth at any particular place for action.
The handle A is usually made straight, and preferably consists of two lateral pieces, z, secured to the sides of a broad intermediate tang.
The edges d and f are Having described this invention, what I claim, and desire to secure by Letters Patent,
1. A push-knife for cutting oil-cloth, having the transverse cutting-edge h at its point portion guarded above by a projecting 1ug,k, and guarded below by a projecting pointed lug, g, substantially as specified.
2. A knife for cutting oil cloth, having its point portion curved upwardly on its lower
