Abstract

Method of cementing together the cap, body and stem portions of electrical insulators, comprising introducing measured quantities of water and cement into the cavities of the cap and body, mixing the ingredients within the cavities and immediately assembling the aforesaid portions into a complete article. The method is particularly useful in production line procedures of producing insulators.

Claims

1. The method of cementing a hollow cap of an electrical insulator, to and exteriorly about the body portion of the insulator, comprising, adding measured quantities of water and cement into the cap, mixing the water and cement into mortar within the cap, and bringing the cap and body portion into final assembled relation with the body portion within the mortar.

2. The method of claim 1, the cap and body portion being assembled together immediately following mixture of the mortar.

3. The method of claim 1, a first portion only of water being added initially, followed in sequence by the measured quantity of cement and remaining portion of water, in the order mentioned.

4. The method of claim 3, said first portion of water being about 1/3 of the total measured quantity.

5. The method of claim 1, and essentially simultaneously with addition of water and cement to the cap, adding measured quantities of water and cement to the hollow body portion of the insulator, mixing the water and cement within the body portion essentially simultaneously with mixing of the water and cement in the cap, and completing the assembly as aforesaid by immersing one end of a stem into the mixed mortar within the body portion.

6. The method of claim 5, first portions of the measured quantities of water only being added into the cap and body portion, followed in sequence by the respective measured quantities of cement and remaining portions of water.

7. The method of claim 6, said first portions each being about 1/3 of the total measured quantities of water added to the cap and body portion, respectively.

8. The method of claim 1, the cement being of an aluminous type, and curing the mortar while maintaining the same at a temperature not greater than about 23°

C., to thereby effect hexagonal type crystallization of the mortar.

9. The method of claim 8, said temperature being about 18°

C.
