' IOLD FOB STORAGE-BATTERY GRIDS.
7 '0 all whom it mag concern:
Be it known that I, LEON B.Hn.r.s,a citi zen of the 'United States, and resident of Lakewood in the county of Cuyahoga and This invention relates to mo ds for storage battery grids or electrodes and one object is to design a mold of such structure that the parts can be readily machined to fit together without exercising more than ordinary care. I
Another object is to produce a mold that will cast a grid of minimum weight for given strength which will be free from fins and have an increased tendency to retain the paste in lace.
A furt er'object is to provide a mold that will extend the side ribs closer to the center of the grid to increase the conductivity without adding to the weight and with increased transverse strength.
Referring to, the drawings:
Figure 1 is a plan view of the upper half of the mold shown in Fig. 2.
Fig. 2 is a section with the halves separated, the lower half only being completely. machined, and the section of the upper half corresponding with the line A-A of Fig. 1.
Fig. 3 is a section similar to Fig. 2, excepting that the mold is completely ma- --chined and the halves are in operative position.
Fig. 4 is a section of the molds in the lane of the line B-'-B of Fig. 1, the halves eing shown in o erative position.
Flg. 5 is a si e-view of a grid cast in my improved mold. v
Fig. 6 is a section on the line C-C, of Fig. Referring to-Figs. 1 and 2, one-half ofa mold 1 is rabbetted at 2 to form the frame of the grid. This rabbet or groove may be put in the molds in well known ways and inasmuch as it is not novel 1 see I have not illustrated the make-up o the mold to indicate I Specification of Letters Patent. Application fled November 80, 1910.
Patented'Aug. 16, 1921.
i this can be done. When the groove 2,
howe ver,-has been formed I machine a plurality'of triangular oves 3 transversely of the mold, forming rldges 4. Then grooves 5 are-machined in the'bottom of the grooves3 as shown in Fig. 3, and cross grooves 6 are cut to form the strengthening ribs of the grid.
The lower half of the mold is made similar to the upper halfexcepting that the grooves 3" and 5 are staggered in respect to the grooves 3 and 5 respectively.
' When thev two halves areplacedtogether moltenlead is poured into'the gate 7 to fill the grooves 2, 5, 5 and 6. After cooling the halves are separated and the grid removed. The structure of the grid is clearly shown in Figs. 5 and 6. The novel feature of the grid resides in the shape of the bottom portion 8 of the ribs 9, this shape being such that the boundary of the cross-section of any rib shows a reentrant angle. Heretofore the ribs have been made with a fiat base, and
my improvement not only reduces the amount of lead required without decreasing the strength, but it also furnishes additional means for retaining the paste.
Also the prongs 9 pro eot-toward the center of the plate and provide means for the current reachingia greater amount of the active material by a path of good conductivity.
To a mechanic it would be a simple matter to machine the grooves 3 and 5 on a planer and when the twolhalves are finished. they will fit perfectly and cause no fins to be formed on the grid.
Having described my invention what. I claim is A mold for battery grids comprising separable halves adapted, when fitted together. to define a series of communicating passages located in parallel planes, each of said passages containing a rentrant angle in the boundary of its cross-section.
In testimony whereof I hereunto afiix my si 'ature.
gn L. B. HILLS.
