I FRUIT-JAR OPENER;

SPECIFICATION forming part of Letters Patent No. 286,836, dated October 16, 1883. Application filed September 1,1883: (No model.)

IO the same, reference being had to' the accompanying drawings, and to lettersof reference marked thereon, which form a part of this specification.

The object of my invention. is to provide a I fruit-jar opener which is simple and cheap in construction, and which avoids the difficulty usually attending the operation of removing the caps or covers of I'ruit-jaraespecially when there has been a shrinkage of the fruit within, or when, from other causes, the cap ad heres to the jar. This I accomplish by a device which has an attaching-hook adapted to catch and bear laterally against the side projection of one nature or the other on all fruit- This hook is pivoted within the confines of a slot at the point of unition of a curved arm adapted to surround the circumference of the cap in a direction opposite to that pursued by the said hook and a 0 handle by which the device is manipulated.

By means of a spring bearing upon an extension of the attachinghook, I keep the same from slipping past the projection on the side of the fruit-jar cover.

5 Figurel is a plan View of my fruit-jar opener, and Fig. 2 is a longitudinal section taken on the line x 00 in Fig. 1.

In the drawings, Arepresents a hook, which has studs 61. a projecting from its pivotal point,

40 and an extension, b, the end of which is preferably turned up to form a shoulder. The studs a a of the hook A are journaled in the open bearings c 0, located in the walls of the slot 03, between which the shank of said hook 5 A is placed, said slot (1 being located at about the point of unition of the curved arm 0 and its handle B. The curvature of the arm 0 is such as to cover a segment of the smallestsize fruit-jar cap, and bear at least on two points on all caps of larger size.

With only the above-described construction cross-bar, e, which bridges over that outer opening of the slot d, as shown, and then placing under it a flat spring, D, one end of which rests in a rabbet, 6, made in the outer surface of the arm 0, adjacent to the slot (1, and the other end of which bears downward'upon the extension b of the hook A. The spring D, bearing, as it does, down upon the extension I), keeps the same, when the device is not in use, against the end wall of the slot at in the handle 13, thus keeping the reach between the arms 0 and the hook A adapted to the smallest regulation-sized fruit-jar cap.

WVhen using my invention, the arm 0 is placed against the periphery of the fruit jar cap, and the hook A is brought to bear laterally against the projection so common in fruitjar caps at that side farthest from the arm 0. Grasping the handle 13, it is oscillated after the manner of an ordinary wrench, thus unscrewing the cap. There isno possibility of the hook A slipping over the side projection of the fruitjar cap above referred to, as the strain thereon is parallel to the tangent struck from the said side projection of the fruit-jar cap, and as the pressure of the spring D upon the extension I) of the said hook effectually avoids such an objection.

\Vhat I claim as new, and desire to secure by Letters Patent, is

l. A device for opening fruit-jars, consisting of a curved arm having a handle extending therefrom, and an attaching-hook pivoted at the point of unition of said arm and handle, substantially as set forth.

2. The combination, with the hook A, having an extension, b, and the arm 0 and handle B, preferably made in one piece, and slotted at about their point of unition, within which the said hook A is pivoted, of the spring D and means for keeping the same in position.

In testimony that I claim the foregoing as my own I hereunto affix my signature in presence of two witnesses. 'GUSTAVE A. M. LILJENGRAUTZ. \Vitnesses:
