FRANK R. ALLISON, 0F- OLEAN, N'E W Yo RKa LIFTING DEVICE FOR GLASS BATTERY-JARS.
Specification of Letters Patent.
Patented Nov. 23, 1920.
Application filed April 10, 1920. Serial No. 372,850.
To all whom it may concern:
Be it known that I, FRANK R; ALmsoN, a citizen of the United States, resident of Olean, in the county of Cattaraugus and State of New York, have made a certain new and useful Invention in Lifting Devices for Glass Battery-Jars; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.
Figure 1 is a perspective view of the in vention as applied.
Fig. 2 is a similar view of the invention and jar detached with the spring grippers contracted.
Fig. 3 is a detail fragmentary sectional View.
The invention has relation to a lifting device for a certain type of glass battery jars, and it consists in the novel construc tion and combinations of parts, as hereinafter set forth.
In the accompanying drawings, illustrating the invention, the numeral 2 designates the glass battery jar, of approximately square form in cross-section and having a contracted top 8 and an upper shoulder 4; upon each of two parallel sides.
The lifting device may be made of light galvanized iron or sheet metal, and consists of a transverse handle 5, bent downwardly at each end to form depending legs 6, in parallel relation and provided at their lower ends at the outer sides thereof each with a laterally extended wood shoe or gripper 7. The metal of which the device is composed is about one-eighth inch in thickness by one and one-quarter inch in breadth, and the shoes or grippers 7 are attached centrally thereof to the aforesaid legs of the device and are each about as long as the width of the contracted top 3, and in lifting the jar are designed to engage the shoulders 4 thereof.
Intermediately of the length of the parallel legs or branches 6 a transverse connection or brace 8 is provided, parallel to the handle 5 and some distance below the same, the legs or branches being thereby rendered rigid, downwardly to said connection, and having a spring action downwardly from said connection or cross-brace, due to the imerent upper end engaging a perforation 13 of said cross brace, a coiled spring 14 surrounding said rod and hearing at one end against said connection and at its other end against said toggle levers.
The operating rod is provided at its upper end with a handle loop 15, and upon pulling upwardly thereon, the toggle levers are bowed as shown in Fig. 2 to draw the branches or legs 6 inwardly and thereby draw the shoes or grippers 7 inwardly sufliciently to escape the shoulders 4 of the jar, preliminaryto engaging the same in p1ac ing the device in position. The device being then let down into the jarsuiiiciently, and the operating rod released, the spring of the branches 6 and of the coiled spring 14 will. force said legs outwardly, said grippers or shoes being carried outwardly therewith into engagement with or below said shoulders. The handle of the lifting device, being grasped, the jar may then be lifted there-. with, the weight of the jar falling upon the elongated shoes or grippers and being distributed therealong so that there will be no tendency to break the glass of the jar, and avoiding any stress or strain upon the glass of the jar that might cause it to fracture or break through temperature changes or expansion and contraction set up thereby.
The jar being lifted and transferred to a new position, the device is released from the jar in the same manner as explained. In lifting the jar, any tendency of the weight of the jar to press the legs or branches 6 inwardly to thereby cause release or droppingof the jar, will be resisted by alined toggle levers, acting as a rigid unit, and being so held by the aforesaid coiled spring.
I claim v A lifting device for glass battery jars, consisting of a transverse handle having parallel depending legs, elongated shoes secured to the outer sides of the lower ends of said legs, a transverse member connecting said legs intermediately of the lengthsthe-re" of and rendering the upper part of the legsrigid against movement and having a cen tral perforation, said legs being of spring nature and inwardly bendable from the ends of said transverse member as centers, toggle levers having pivotal connection with the lower ends of said legs a pull r0d slidablv engaging said perforation and at its lower 10 end having pivotal engagement Wltll the FRANK R. ALLISON.
