SEPARATOR AND SPACER FOR STORAGE BATTERIES Filed Oct. 18, 1927 mar/es /4 7;

13 MM (its Patented June 2, 1931 UNITED STATES CHARLES W. TERRY, OF DETROIT, MICHIGAN SEPARATOR AND SPACER FOR STORAGE BATTERIES Application filed October 18, 1927. Serial No. 226,855.

A separator and spacer embodying features of the invention consists of two parts, one a framework or grating having on one face thereof top and bottom ledges and having on the other face spaces extending across the horizontal bars of the grating and provided by extensions of the vertical bars of the grating, and the other a flat member or panel fitting between the ledges and lying against the vertical bars of the grating and covering the latter. The grating is made of hard rubber or similar insulating and inert material having Considerable .mechanical strength and the flat sheet or panel is of wood veneer. In use the hard rubber grating is arranged adjacent to the positive pole plate and the wood veneer is arranged against the face of the negative pole plate.

From the foregoing and from the follow- 29 ing description the objects of the invention will appear and the invention will be claimed at the end hereof.

The following description will be made in connection with the accompanying drawings forming part hereof and in which Figure 1 is a View of a separator and spacer embodying features of the invention viewed from the grating'side.

Fig. 2 is a sectional View taken on the line 22 of Fig. 1, and

Figs. 3 and e are perspective views respectively of the panel and of the grillage.

Referring to the drawings, the insulating inert grating of suiiicient mechanical strength illustrated in Fig. 4 comprises a pair of spaced horizontal bars 1 and 2 having a series of spaced vertical bars 3 crossing the horizontal bars and laid upon them. Ledges 4 are provided at the top and bottom of the grating and on one face thereof. '5 is a Wood veneer panel and it is fitted between the top and bottom bars or ledges and lies against the vertical bars.

It will be observed that the faces of the vertical bars of the grating and the faces of the top and bottom bars which are in contact with each other lie in the same plane, and the bars of the grating project from one side of that plane while the top and bottom bars project from the other side.

Advantages of this construction are that the hard rubber grating serves as a mechanical spacer between adjacent storage battery plates and takes no strain caused by a tendency to buckling or any abrasion due to shifting of the relative positions of the positive and negative plates. The grating also serves to keep the wood veneer away from the face of the positive pole plate and therefore out of contact with the lead per- 00 oxide which has a tendency to oxidize and disintegrate the wood sheet or panel. The grating does not interfere with vertical circulation of electrolyte nor with the escape of gas bubbles and it allows free passage for any active material which may be dislodged from the positive plate to fall to the bottom of the jar. This because of the channels provided as at 6 between the vertical bars 3.

Under some conditions it is desirable that the grain of the wood veneer shall be horizontal. My invention is well adapted to provide for this since the vertical bars 3 will then bear upon the wood veneer across its grain, and in this position the wood veneer is less likely to be indented or abraided by these bars.

It will be obvious to those skilled in the art to which the invention relates that modifications may be made in details of construction and arrangement and in matters of mere form without departing from the spirit of the invention which is not limited to such matters or otherwise than the prior art and the appended claim may require.

I claim:

A storage battery separator and spacer comprising a grating consisting of horizontal top and bottom bars and spaced vertical bars, the two sets of bars projecting oppositely from a common plane,'leaving channels be tween the ends of the vertical bars across the horizontal bars, and a panel of porous material lying between the horizontal bars and against the face of the vertical bars.

CHARLES WV. TERRY.
