TROLLEY-WIR 'HANGER.

Specification of Letters Patent.

Application filed July 31, 1916." Seria1'N0. 112,343.

ToaZl whom it may concern:

Be it known that I, FLOYD Gr. BOVARD, a citizen of the United States, residing at Mansfield, in the. county of Richland and State of Ohio, have invented certain new and useful Improvements in T rolley-Wire Hang-v ers, of which the following isa specification" My invention relates to that class of de-' vices which are known as trolley hangersand intended for suspending trolley wires andmore particularly wherecatenary construction is used.

My invention has for it object the suspending oftrolley wires fromra messenger cableor other support and the economy and convenience of installation of the device are given: particular attention in its construc tiOn;

Another object ofmy device is-to be capable ofmaintaining all of its parts in engagement while being installedor removing from the installedposition;

Another ob'ect is to produce a hanger which-is simple tomanufacture and hence the improvements herein described and shows the hanger in installed position, suspending a trolley wire from a supporting cable.

Fig. 2 is an end elevatlon new of myinvention taken at right angles to Fig.- 1.

Fig.- 3 shows the hanger in Figs. 1 and 2 in partial section as having its clamping jawssprung apart ready to install on the supporting cable or to remove from the supporting cable.

Figs. 4and- 5 show front and end. elevation views ot a modified form of my invention shown in Figs. 1 and 2; it being understood that the upper part of the device is the same asshown in Figs. 1 and: 2 and the.

operationis the same as in-Fig. 3 except with the modification as brought out here;

inafter.

I have foundm construction work of installlng trolley wires that it is a decided advantage touse a: hanger for supporting the,

trolley wires which will have the parts of which the hanger is composed so constructed and arranged that during the operation of installing the trolley wire, the parts of the hanger; cannot be separated entirely from each other'or atl'east the device will be one.

in which it is not necessary to entirely sepa-' rate'the parts. This is of particular advantagewhen it is considered that much of this work is done on the top of tower wagons orcars mextreme cold weather and when t is necessary forthe workmen to wear thick heavy gloves which makes their-movements, clumsy and hencethey will be liable. to drop theparts it it isneoessary to completely separate them. The same is true in changing hangers on a trolley which is charged withelectric currents and it is necessary to handle the parts very cautiously. I- have also found that it is very desirable to do. this work in as. little time as-possible thereby cutting: down the expense of construction and I-have covered this point in my arrangement of parts.

The invention consists of a U shaped sus; pension-member 1 which in itsinstalledposition will hang from a suspension cable2.

at the point of bend. Numerals 3 and: 4 show the clamping jaws for attachment to Patented-Dec. 25. 1917.

the ends of the suspension member 1 andfor gripping and holding the trolley wire 5. The clamping jaw 3 is provided in one, face with a recess6 for seating the head 7 of a-v clamping bolt and 1s also provided with an.- aperture 8 dlsposed at an angle to the recess 6 and through which the head 7 of the bolt is passed to engage and disengage-it with the clamping aw 3; a turn of the bolt after being passed through the aperture 8 will seat the bolt head? in the recess 6.

' The clampmg aw 4 is provided with. an aperture large enough only to receive the shank 9 of the bolt, the end of which is;

threaded and supplied. with a lock washer,

IOand a nut 11. The reces 6, aperture 8;

and bolt headfican-be ofavarious shapes and sizes and; still: perform; the. function of, my;

invention. In Figs. 1, 2 and 8 the lower end of the suspension member 1 is attached to the clamping jaws 8 and a by a rivet 12, although other means may be employed giving equally as good results and coming within the scope of my invention. The recess 6 being depressed prevents the head 7 of. the clamping bolt from turning when tightening the nut 11. In Figs. Land 5 I have shown a modification in that the lower end of the uspending member 1 is brought down and underneath the head 7 of the clamping bolt and underneath the spring lock washer 10, and the lower ends are supplied with apertures corresponding to the head 7 and shank 9 of the bolt. The extreme ends of the suspension member 1 which is attached to the clamping jaw 3 are bent outwardly to form the lug 13 which prevent the head 7 of the clamping bolt from turning when drawing the clamping jaws into place on the trolley wire.

The operation of installing my invention is as follows: The nut 11 is loosened up suiticiently to allow rotating the bolt one quarter turn which causes the head 7 to register with the aperture 8. The jaws 3 and at will now spring apart as shown in Fig. 3. The hanger is now placed on the suspension cable 2 as shown, none of the parts being entirely disengaged. The trolley wire is now lifted up into position between the jaws 3 and a which are sprung together by hand upon the trolley Wire and the clamping bolt placed in clamping position by passing the head 7 through the aperture 8 and giving the head one quarter turn and drawing the nut 11 up tight.

To remove the hanger after being installed it is only necessary to go through the reverse operations as are required to install my hanger. It is sometimes the practice in overhead construction of electric railways to use two trolley wires, one above the other and parallel to each other and my invention is equally as applicable to supporting two conductors as one, it merely being necessary to adapt the clamping jaws to holding two wires in place of one.

Many variations from the above disclosures will be obvious to one skilled in the art and I do not wish to be limited to the specific construction shown in the drawings and disclosed herein.

I claim 1. A suspension device for trolley wires comprising a U shaped suspension member, a clamping jaw attached to each end of the suspension member, a groove on each jaw registering with the groove on the other jaw for engaging a trolley wire, an aperture in each jaw opposite each other and a clamping bolt provided with a head, and tightening means passing through both apertures, the head being adapted to engage one of the venting the passage of the bolt head there through. s V

3. A suspension device for trolley wires, comprising a' pair of clamping jaws maintained in co-acting position by a U shaped suspension member and made to grip a trolley wire by means of a clamping bolt with upset end arranged to be engaged with and disengaged from one of the clamping jaws by an angular movement of the clamping,

bolt.

4. A suspension device: for trolley wires comprising a pair of clamping jaws and means passing through the jaws for maintaining the jaws in clamping-relation on a trolley wire, the clamping means having anupset end for engagingwith or disengaging from one jaw by an angular movement.
