ABSTRACT:
A canning jar lifter with pivoted cross rails having loops at each end which are capable of fitting regular or wide mouth conventional canning jars externally around the neck below the seating rim and by manual operation capable of gripping the jars for lifting and self-adjusting for releasing them.
The embodiment of this invention which is illustrated in the drawings and will be described in more detail hereinafter is shown as comprising a continuous strip of resilient material welded or otherwise firmly affixed end to end. Said material is of a size and so formed as to have a small loop at one end and a large loop at the other end adjoined by rails which are crossed over and pivoted. The rails are flattened in the pivot area and pinned so as to be movable. The loops extend in opposite directions at right angles to the rails. One loop is made so it will fit easily over the neck of a large mouth canning jar. The other loop fits easily over a regular sized canning jar neck. Squeezing the rail ends of the top loop (whichever is up) causes the lower loop to tighten around the jar neck on which it is being used. The loop catches the jar neck just below the seating rim and holds the jar firmly for lifting. Relaxing the pressure on the upper loop rails allows the resilience of the material reinforced by the spring tension in the loops to self-adjust the loop being used back to the original open position. This self-opening of the loops facilitates easy releasing of the held jar. For better gripping and protection to glass jars, the looped ends may be dipped or otherwise coated with a rubberized or suitably pliant material.
