JAR-CAP SPAN N ER.
SPECIFICATION forming part of Letters Patent No. 468,804, dated February 16, 1892,
Application tiled April l, 1889. Serial No. 305,556. (No model.) I
i To @ZZ whom it may concern.-
Be it known that I, GEORGE I. l-IoBBs, of Vheeling, in the county of Ohio and State of \Vest Virginia, have invented a new and useful Improvement in Jar-Cap Spanners, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part ot this specification, in which- Figure l is a perspective view of my improved spanner applied to a jar-cap. Fig. 2 is a perspective view of the spanner detached.
Like symbols ot' reference in dicatelike parts in each.
The object of my invention is to provide a Spanner which can be used to remove j ar-caps without providing the latter with projecting lugs, stops, or similar devices.
In the drawings, 2 represents an internallythreaded fruit-jar cap of the ordinary sort. The Spanner consists of a piece of cast-iron, comprising a circular portion or partial annulns 3 of substantially the same'or a little less internal diameter than the external diameter of the cap. This ann ulus is not complete, but is divided, and its divided ends eX- tend outwardly, forming handles 4, the ends of which are turned inwardly, one or both of them being preferably provided at the end with a button or enlargement 5. The annular portion of the spanner is shaped as shown in the drawings, having a peripheral strengthcning rib or iiange b and being gradually enlarged in width from the middle portion toward the ends. This imparts to the spanner the necessary elasticity and flexibility, enabling it to be made of cast-iron and strengthening it so that it may be used without danger of breaking. The buttons 5 are designed to prevent the handles 4 from being compressed suiiiciently to fracture the Spanner.
In using the Spanner the annular portion 3 is iitted around the cap, and the operator, grasping the handles 4 and squeezing them together by reason of the elasticity of the Spanner, clamps the annulns firmly on the cap, so that by moving the handles laterally the cap may be unscrewed, and when it is unscrewed it may be lifted oit with the Spanner without touching the cap with the hand, and by making the Spanner of the same diameter as the cap or of a little less diameter the spanner will not ot itself fall ott the cap when the hand is removed.
The advantages of my improvement have been demonstrated by use and will be apparent to those familiar with this class of instruments. and durable, and is very efficient for the purpose for which it is designed, enabling the jar-caps to be removed or tightened without requiring the use of special stops or lugs on the cap, as does the form of Spanner now in common use.
I claiml. A spring-Spanner for jars, consisting of an open cast-iron annulns having radiallyprojectinghandles, the body of the annulns tapering in cross-section from the point of division to a point diametrically opposite thereto, substantially as and for the purposes described.
2. A spring-Spanner for jar-caps, having a divided annular portion provided with a peripheral flange or rib which increases in crosssectional size in both directions from its middle portion and terminates in outwardly-projecting arms forming clamping-handles, substantially as and for the purposes described.
3. A spring-Spanner for jar-caps, composed of a divided annular portion having a peripheral iiange or rib increasing in cross-sectional size in both directions from its middle portion toward the ends and terminating in outwardlyprojecting arms forming clampinghandles, said arms having inwardly-projecting knobs or buttons at their extremities, whereby the spring of the annular portion is limited, substantially as and for the purposes described.
In testimony whereot I have hereunto set my hand this 27th day of March, A. D. 1889.
GEORGE P. IIOBBS.
