BURR E. CALDWELL, OF NIAGARA FALLS, NEW YORK, ASSIGNOR TO U. S. LIGHT & HEAT CORPORATION, OF NIAGARA FALLS, NEW YORK, A COEPORATON OF NEW YORK.

Application filed September 24. 1317, Serial No. 192,880. Renewed June 24, 1922. Serial No. 570,719.

The present invention relates to plate supporting means.

In large storage batteries, as for instance, those used in marine service, it is necessary 5 to provide special means for supporting the storage battery plates. In lifting the plates out of the cells for the purpose of inspection, or for any other purpose, it is common practice to do such lifting by means of the cell posts. It is common practice to provide four cell posts for each cell and the lifting is done on all four posts, whereby to reduce the stresses on the plates to a minimum. As the plates are lifted out of the cell by the cell posts, the plates of one polarity tend to swing away from the plates of the other polarity. To overcome this tendency, it has been common practice to bandage the plates together after they are drawn part way out of the cell.

The present invention has for one of its objects the provision of plate-supporting means whereby the plates may be securely supported from the walls of the cell.

A further object is to provide plate-supporting means which will cooperate with the plates in .such a way that when the plates are lifted from the cell, said plateswill be locked together, whereby the tendency of .m the plates to swing apart will be effectually resisted.

A further object is to provide a construction in which treeing across from plates of one polarity to plates of the opposite polarii ity will be minimized.

Referring to the drawings- Figure 1 is a sectional view illustrating one embodiment of the present invention.

Figure 2- represents on a larger scale a plate-supporting member according to the present invention.

The walls of a battery cell are indicated by the numeral 1. A number of plates in said cell of opposite polarities are indicated respectively by the numerals 2 and 3. Straps 4 connect all of the plates 2, which are of one polarity, while straps 5 connect all of the plates 3 which are of the opposite polarity. As stated above, it is common practice to provide a pair of cell posts for each of the straps 4 and 5, which cell posts will be placed adjacent to the opposite ends of each strap. Each of the plates 2 and 3 may be of the same configuration and is prothe lugs 6, 6. Each ofsaid shoulders 8, 8, i

also supports a supporting member 9 which is of comb-shaped formation. The teeth' 10 of said member 9 are adapted to straddle the lugs 6 of the plates 2 and 3. The lugs 7 of the plates 2 and 3 are adapted to rest upon the top of a member 9. By this construction the lugs 6 of each plate will be supported on the one side by a shoulder 8 and on the other side the lugs 7 will be supported by the member 9 which in turn is Supported by a shoulder 8. The space between the lugs 6 of the plates of one polarity and the lugs 7 of the plates of opposite polarity should be sufficient to receive the transverse portion of the member 9 lying above the space between the teeth 10. Said transverse portion of the member 9 should fit loosely between adjacent lugs 6 and 7, when the plates are in position in the jar. WVhen it is desired. to lift the plates out of the cell by the terminal posts, said members 9 will effectually lock the plates against turning movement relative to one another, whereby no bandaging of the groups will be neces sary.

It will be noted that the adjacent sides of plates of opposite polarity are supported at different levels, whereby should. any deposit form either on the shoulders 8 or upon the members 9, said deposit cannot possibly form a short circuit between plates of opposite polarity.

According to the present invention a very sturdy construction is provided which is cheap to manufacture. in which short-cir cuiting is minimized and in which handling is accordingly facilitated.

It will be noted from the drawings that the cross-section of that portion of the member 9 above the space between the teeth 10 is a parallelogram having other than right angles. It will be clear that any other angular relation may be provided if desired.

The described embodiment of the present invention is chosen merely for the purpose of illustration and is not to be ccnsidered.

a limiting sense. Many modifications may be made therein, It is desired that the patent shall cover all such modifications that come within the scope of the invention as defined by the appended claims.

WVhat I claim as new and desire to secure by Letters Patent of the United States, is-- 1. In a battery cell, a jar having shoulders on opposite Walls, plates each having lugs on opposite edges thereof, certain 0t said lugs being adapted to rest directly on certain of said shoulders, and supporting meanson each of said shoulders uponwvhich other of said: lugs are adapted to directly rest. I

2. In battery cell, jar provided with means for supporting battery plates from the side walls, plates in said cell, each of said pla-teshaving side lugs, the lugs on adjacent sides of alternate platesbeingz; spaced apart vertically, and a plurality of combshaped members each having its teeth rest ing upon said first mentioned means, the transversely extending portion of each of said comb-shaped members lying between said spaced apart lugs.

adapted to abut against opposite parts of I said plates to prevent swingmg movement of said plates, and a jar for said groups, said jar being provided With transverse means for directly supporting portions of said plates and said transversely extending means, said transversely extending means being adapted to directly support other portions of said plates.

4. A battery cell having a side wall pixevided With a shoulder, battery plates iaving their edges adjacent to'said side Wall, alternate plates having lugs adapted to rest upon said shoulder, a combshaped member having teeth resting upon said shoulder and straddling said lugs, the remainder of said BURR H.
