GUY MARDOCK, OF ILLINOIS CITY, ILLINOIS. l

INsU'LAroR-surronr.

TQ all may concern:

Be it known that I, GUY MARDooK, a citi` zen of the Unitedy States,residing at Illinois City, in the county of Rock Island and State of Illinois, have inventedA certain new and useful Improvements in: Insulator-Supports,

of which the following is a specification, reference being had to the accompanying draw- This invention comprehends certain' new and useful improvementsin cross arms ,for

telephone and telegraphp'oles and has for its primary object to provide a device of this character which will bestrong and durable,

as well as highly efficient in use. e y

Another object is to provide a device 'of this character yin which the insulator is securely fastened upon thebracket secured to the cross. arm, thereby eliminating all danger of the insulator working 0H of the further object is to generally improve and simplify the construction of devices of this character and increase the 'eiciency thereof, without increasing the cost of the same. Y l With the above'and other objects in view,

of parts to be hereinafter more fully described, claimed, and illustrated in the accompanying drawings, in4 which,

Figure 1 1s an elevational view of my com- V l pletedevlce m use; Fig. 2 1s a transverse` sectional view thereof; and'Fig. 3 is a detail elevational-view showingonly a portion of the cross arIn.

Referring more ispeciiically to Athe draw ings in which similar reference characters designate corresponding 'parts throughoutthe several views, 1 designates vthe cross ,arml

which is formed of anglefiron and adapted to be secured to a telephone or telegraph pole by bolts 2 or other suitable means, one angle of the arm being positioned against thepost while the remaining angle projects laterally Ifrom the same. Uponthe last. mentioned angle of the `cross arm are 'positioned the upstanding ,insulator supports 3 rupon the upper ends of which are threaded or otherspeciflcationfof Letters Patent.

wise engaged, the insulators'- 4 formed of any sultable non-"conducting material such as glass. The upstanding insulatorsupports 3 are secured in position upon the upper face of the laterally directed cross arm 1 by the bolts 5 extended longitudinally therethrough and through theangle of the cross arm upon' which the insulator'supports are positioned,

n said bolts also extending .through the insula-` tors 4 and having` their slotted heads 6 engaged upon the upper ends of said insu'la'-v tors. The bolts 5 therefore, serve to securely fasten theinsulators in'position .upon the insulator supports 3, as well assecuring the latter upon 'the cross arm, it being understood that a nut 7 or the like is secured upon the lower end of each bolt 5.,

It will be apparent that the cross arm 1,

insulator "supports 3, and bolts' 5, are formed of any suitable material, while the insulators are formed of glass or other suitable durable non-conducting material, ltherebyV 'providing a complete device which will be strong and durable as well as highly ei'icient in use andY cheap and easy to manufacture and assemble.

If desired, a brace bar 8 may be employed as a further support fontina curedto the pole below the cross bar.

While I have shown the preferred embodiyment of my invention, it will be understood that Aminor, changes in the` details of construction and arrangementofparts` may be made within the scope of the appended' claimwithout departing from the spirit ofv my invention or sacrificing vantages of the same. e

What is claimed is a base, an insulator support having a ta l ered upper end mounted upon the base. an insulator having a tapered recess formed 1n itslower end fitting snugly upon and being` engaged over said support, said support and insulator having central longitudinal regis# tering openings therethrough, a bolt. adapted for engagement through said registering openings and through the base tosecure the any of the ad 1 cross arm, one end of the brace bar being e ,i secured to the crossarm near one end theren of, the opposite end ofthe bar l8 being kse.
