INSULATOR-PIN MOUNTING.
Specification of Letters Patent.
Patented Nov. 19, 1907.
Application filed January 21, 1997. Serial No. 363,176.
To all whom it may concern:
Be it known that 1, JOHN D. E. DUNCAN, a citizen of the United States, and a resident of the borough of Brooklyn, county of Kings,
city and State of New York, have invented certain new and useful Improvements in Insulator-PinlVlountings, of which the following is a specification, taken in connection with the accompanying drawings.
This invention relates to insulator pin mountings, and relates especially to mounting heavy insulator pins such as are used with high tension power transmission insulators, so as to securely and rigidly hold them in position.
- In the accompanying drawings showing illustrative embodiments of this invention, Figure 1 is a top view, Fig. 2 is a corresponding vertical section, Fig. 3 is a vertical section of another form of the invention, Fig. 4 is the corres onding top view, Fig. 5 is a vertical detai section through the pin, and Fig. 6 shows the general arrangement of such mountings, on a skeleton tower.
In the illustrative embodiment of this invention shown in Figs. 1 and 2, 1, is the insulator pin which may be of the tubular metallic construction indicated, the insulator being mounted at the top of the pin in a well known manner. The cross arm 7 may be of wood, if desired, and is preferably formed with a suitable recess to accommodate the flange 9 of the support 8. This support may also be provided with the transverse ribs 24, which may be seated in suitable cooperating depressions in the arm in the form of sawcuts or the like, and the ribs 24 may diverge downwardly so as to prevent the support moving upwards after the'ribs are seated in the arm. The support is preferably provided with a plurality of saddles 10, 11, which may be conveniently stamped up from the rest of the support if it is made of sheet steel or similar resilient material or may be readily formed by casting or in other ways. These saddles are as indicated, curved to form a seat for the pin, the curvature oflthe saddle being preferably of slightly less radius than the outside of the pin so as to be first engaged by it at two separated points and thereafter the pin may be firmly seated by the slight yielding of this resilient saddle, which thus has a slight gripping engagement with the pin. The lower saddle 1 1 may be provided with a connected bracket 13, to support the bottom of the pin and with a lug 12, to engage a suitable socket22, in the pin, which may be formed as indicated in Fig. 5.
The support 8, and saddles are first placed in position on the cross arm 7, and the pin 1 arranged in proper position in cooperation therewith. Then the attaching means which may be in the form of the encircling U-bolts 2, 3, are inserted in suitable holes in the saddles and arm and the nuts 4 set home to clamp the parts in position, preferably in connection with suitable vertical straps 6. These U-bolts do not require any aperture in the pin itself or weaken its strength in any way, and in practice may be adjusted so as to cause the resilient saddles'to conform properly with the contour of the pin and also to force these saddles and other parts of the mounting into engagement with the arm sulliciently so that the pin is held with a spring action causcdby the elasticity of the various parts.
The other figures of the drawings indicate a modification in which the insulator pin is shown applied to asteel tower comprising the pillars 20, secured by the stays 22, 23, having suitable skeleton arms 14, 14 and 15, 15, which may be held in proper position by the lattice bracing 21 indicated. A plurality of resilient saddles 17, 18 are preferably secured to the skeleton arm and may be formed with curved gripping resilient seats of a curvature slightly greater than that of the outside of the insulator pin 1, so as to be depressed at the central point of first engagement and thereafter conform properly to the pin when the parts are clamped together by the nuts 4, 5 on the U-bolts 2, 3, encircling the pin, which are preferably so adjusted as to support the pin with a spring action due to the elasticity of the arts.
If desired, the sad les may be provided with the flanges 16, 19, to engage the arm and maintain alinement therewith, and the flanges may fit between the bracing 21 to prevent horizontal movement on the arm, and with a suitable lug 12, to engage a corresponding socket 22 in the pin 1 to hold it firmly in proper vertical alinement as is indicated in Fig. 5.
Having thus described this invention in 1 connection with the several illustrative embodiments thereof, to the details of which it as new and what is desired to be secured by Letters Patent is set forth in the appended claims.
