WILLIAM F. HARVEY, OF LIMA, NEW YORK.

METHOD AND APPARATUS FOR GEMENTING INSULATQRS Application filed June 26, 1925. Serial No. 39,849.

To all whom it may concern:

Be it known that I, WILLIAM F. HARVEY, a citizen of the United States of America, residing at Lima, in the county of Livingston and State of New York, have invented certain new and useful Improvements in Methods and Apparatus for Cementing Insulators, of which the following is a specification.

My invention relates to. a method and apparatus for cementing together the porcelain view, and

sections or other parts of an insulator, and

has for its object to subject the insulator to such treatment as will entirely eliminate air pockets and cracks, by causing the cement to flow freely and settle evenly in the insulator.

The invention consists of imparting rapid vibration to an insulator while pouring cement therein, and in the provision of a sup-' port or table that permits pouring cement and holding the insulator for any desired period of time thereafter, while continually subjecting it to rapid vibration during the operation of pouring and thereafter. as long as it is resting on the table or support.

To these ends, the invention includes the procedure and apparatus that will appear clearly from the following description when read in conjunction with the accompanying drawings, the novel features being pointed out in the claims following the description. l

In the drawings:

Figure 1 is a plan view of a preferred structure according to which my improved method may be carried out;

Figure 2 is a side elevation;

Figure 3 is an end view; I

Figure 4 is an enlarged vertical sectional Figure 5 is a detail sectional view of the ibrating means and supporting plate there In some cases, the procedure in cementing together two or more porcelain sections of an insulator is to invert the insulator and pour the cement by means of a gun or other suitable device between the adjacent walls to be united, and my improved method consists in rapidly vibrating the insulator either during the cement pouring operation or afterwards, or both while and after the cement is poured, in order to effect a thorough mixin and even settling of the cement while 'quid.

This'result may be effected in a variety of ways and with 'diflerent types of machines, and according to one method, I effect a vertical vibration of the insulator at approximately 700 to 1000 vibrations per minute. This result can be had by positioning the insulator on a rapidl vibrating table or support, and to this on I may employ a slightly flexible sheet metal table or support 1, mounted on legs 2, and provided with abearing 3 in which is mounted the rotary turntable or carrier 4' upon which each insulator is positioned to permit turning while the cement is poured.-

'After the insulator is cemented, it is removed from the rotary carrier 4 and placed on the table 1 and permitted to remain there for a sufiicient length of time to cause thorough settling of the cement, the insulator being subjected to rapid vibration preferably both while it is on the rotary carrier 4 and While on the table 1. This vibrating action may be at approximately 700 to 1000 vibrations per minute, and is continued for a period of about two or three minutes under ordinary conditions, although this may be varied depending upon conditionsin a particular case.

To effect the necessary vibration of the table 1, there is fixedly connected to its underside a vertical plate 5 having a horizontalportion 6 that lies adjacent to and is attached to thetable, while 7 designates a weakening characteristics in the cement.

, -While I have described the invention with reference to a particular mechanism, it is to be understood as not confined to the structure set forth, but the method may be carried out byother forms of mechanism without 'departin from the underlying features of the improvement or the scope of the following claims.

I claim:

1. The method of cementing together the parts of an insulator, consisting in subject ing the insulator to rapid vibration While the cement is poured therein.

2. The method of cementing together the parts of an insulator, consisting in subjecting the insulator to rapid vibration for a short period of time after the cement is poured therein.

3. The method of cementing together the arts of an insulator, consisting in subecting the insulator to rapid vibration during pouring of the cement therein and for a short period of time thereafter.

4. The method of cementing together the parts of an insulator, consisting in positioning the insulator on a rapidly vibrating table while the cement is poured therein.

5. The method of cementing together the parts of an insulator, consisting in positioning the insulator on a vertically vibrating table during pouring of the cement therein and for a short period of time thereafter. 6. Means for supporting an insulator While cementing it comprising a sheet metal table, a rotary carrier mounted on the table to support and permit turning the insulator while the cement is poured therein, and mechanism operatively connected to the table for vibrating it vertically.

, 7. Means for supporting an insulator While cementing it comprising a sheet metal table, a vertically arranged plate fixed to said table, and vibrating means carried by the plate.

8. Means for supporting an insulator While cementing it comprising a sheet metal table, a rotary carrier mounted on the table to support and permit turning the insulator while the cement is poured therein, a vertically arranged plate fixed to said table, and vibrating means carried by the plate.

9, Means for supporting an insulator While cementing it comprislng a vertically vibrating table, and a rotary carrier mounted on the table to support and permit turning the insulator While the cement is poured therein.

In Witness whereof, I have hereunto signed my name.

WILLIAM F. HARVEY.
