INSULATOR SUPPORT FOR CROSS ARMS.
APPLICATION FILED AUG.9. I915.

WITNESSES CHARLES C. SAYLOB, OF PITTSBURGH, PENNSYLVANIA.
INSULA'I'OB-SUPPORT FOR CROSS-ARMS.
Specification of Letters Patent.
Application filed August 9, 1915. Serial No. 44,418.
- To all whom it may concern:
Be it known that I, CHARLES C. S.A1 'LOR, a citizen of the United States, residing at Dormont, Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Insulator-Supports for Cross-Arms, of which the following is a specification.
My invention consists of an insulator support adapted to be removably mounted on the cross arm of a telegraph or other wire supporting pole, and it has for its object to provide a device of this class which may be securely located in position and easily removed or shifted, and which is not subject to the deteriorating effects of weather.
The device comprises a U-shaped band adapted to embrace the cross arm and having attached at its corner or corners one or more insulator supports, together with a hinged locking bar and attached holding and locking mechanism, as hereinafter more fully described.
Referring to the drawings, which show one preferred form of the invention,
Figure 1 is a perspective view of the device, detached.
Fig. 2 is a cross sectional view through the device in position on a cross arm.
Fig. 3 is a partial view showing the looking mechanism in elevation.
Fig. 4: is an under plan view.
Figs. 5 and 6 are detail views showing modified constructions of pin mounting for the insulator.
The cross arm 2 of a pole is usually of wood, of standard cross section, as 3 by 4 inches. The main body portion of the support consists of a clamping band 3 of metal, preferably malleable iron, formed with three embracing sides adapted to fit around the top and sides of the cross arm. Extending from one or both corners of the band, or
from any other portions thereof, are the outwardly projecting insulator pins 4 which 16, so that the several In case an integral metal pin is used, it may be vertically divided by one or more cross slots 6 throughout all or a portion of the threaded part of pin 8, thereby providing for any desired degree of resiliency to .avoid breaking the insulator, as shown in Fig 6.
he sides of the clamp 3 terminate in a hinge 9 at one lower corner and in upturned divided ends 10, 10, at the other corner.
By this means I provide a hook socket 11 Patented June 26, 1917. I
having an upper open side, adapted to receive the cross bar 12 of a locking, link 13. Link 13 is pivoted at 14 to a clamping bar 15 between its ends, and the bar is pivoted by one of its ends to the end of a clamping plate 16 which is pivoted at the hinge terminal 9 of the main clamp 3. Bar 15 is pivoted at 17 to the other or free end of plate arts as thus connected may swing away rom the cross arm on the hinge 9. The pivotal connection 14 is as close as practicable to the pivot joint 17 and will thus swing around said joint as a center in action. The other end of bar 15 is provided with a ring or hook 18 for easy manipulation.
The manner of application will be readily during placing of bar 12 in sockets 11, and
The device is very simple, cheap, eflicient and durable. The working parts avoid the use of nuts or threaded stems which are very apt to corrode and become useless, and the working parts themselves are all underneath and protected from the weather. The construction and advantages of the invention will be readily understood and appreciated by those familiar with this class of mechanism. It may be so changed or varied in proportions or details by the skilled mechanic within the scope of the following claims.
What I claim is:
1. Fastening means for a three-sided rectangular insulator support of the construction described having a hinging terminal at one side and an up-turn'ed double centrally divided open socket terminal at the other side; consisting of a swinging clamping plate pivoted to said hinging terminal and adapted to form a fourth closing and holding side, a locking bar pivoted to the free end of the clamping plate, and a link positively pivoted to the locking bar adjacent its pivotal connection with the clamping plate adapted to engage said open socket terminal.
2. Fastening means for a three-sided rectangular insulator support of the construetion described having a hinging terminal at one side and an up-turned double centrally divided open socket terminal at the other side; consisting of a swingingclamping plate pivoted at one end to said hinging terminal and having its free end apertured, said clamping plate being adapted to form a fourth closing and holding side, a locking bar pivoted in the aperture in the free end of the clampin plate, and a looped holding device positively pivoted to the locking bar adjacent its pivoted end and adapted to engage said open socket terminal and be tightened therein upon throwing said bar around its pivot and against the clamping plate.
In testimony whereof I hereunto aflix my signature in the presence of a witness.
