' Another object is to provide a device which may be adapted to various wire conditions by merely changing certain parts, thus avoiding the necesr sity of making up an entire new device for each wire condition.

Other objects will be hereinafter disclosed and be evident to those skilled in the art.

My invention resides in the new and novel construction, combination and relation ofv the various parts disclosed in this speciiication and the accompanying drawing and set forth in' the claims.

invention.

on the In the preferred embodiment of my invention I make use of a body member I of predetermined length. The body member comprises an `elongated web 2 having a threaded boss 3 by means of which the device is attached to an overhead support. The web portion 2 is provided at its ends with transverse openings 4 and 5 and is, also,

providedwith intermediate transverse openings lh The web portion 2 is, also, provided with an upper flange 1 andlower flanges 8 and 9 which add materially to the strength'of the body'memi i ber inresisting bending.

To each end of the body member is secured a detachable end Ill which is provided with spaced flanges II forming therebetween a groove to receive the end portion I2 of the web 2. The flanges II' are provided with transverse openings which register with the openings 4 in the portion I2 of the web and the member 2 and the end members I0 are secured in position by means of through bolts I3.

The end members I0 and the body member I are of metal and in electrical contact.

The end members Ill are provided with means for receiving the ends of the trolley wire I4. As

application Serial No. This application August `9,

with a current there are many types and sizes oi trolley wire, it is advantageous in many ways to have the end members vIII detachable from the body member I, thus, making it possible through the use of a single body member to adapt the device to the various sizes and styles of trolley wire by merely forming the end members I0 to meet the different wire conditions then applying them to the body member as required.

, The trolley wire I`4 of set screws I5.

Intermediate theends of the body member I is a contact member I6 provided adjacent each end with apair of spaced lugs I'I. Each pair of lugs is provided withA transverse openings which register axially wi h the openings in the body member I. v

In the class of devices in which this invention falls it is important that the contact member I6 be insulated from-the trolley wires I4 and, therefore,A I place .an insulating bushing I8 in each opening '6 and insulating washers I9 on opposite -sides of` the web 2 and interposed between the web and lugs I1.

The contactmember I`6 is heldin position with respect to `the bodyv member I by means' of vthrough bolts 20. If desired, the insulation between-the contact member and the body member may bemodied from that disclosecLbut I find the arrangementdescribed simple and eflicient. The ends of the contact member I6 are spaced a somewhat considerable d` tance from the ends of the vmembers I0 and I position in such space arcing tps2 I, each provided with a pair of spaced lugs 22 provided with openings 23 which register with the openings 5 in the body member I.

Each arcing tip 2I is in Contact with the body -member I and has one face 24 abutting the adjacent end face 25 of the' end member I6 or in very. close relation thereto. The other face 26 lof the arcingitip 2l is spaced from the adjacent endv face 21 of the contact member'l and the faces '26 vand 2'Ik are parallel but disposed diagonally with respect to the longitudinal axis of the device. n

The lower surfaces 28 of the trolley wire and 29 of the arcin'g-tip 2I and 3b of the contact member I6 arev in alignment, thus permitting a smooth passage of the current collector 3l across the device and when the collector tl passes from the part 2! tothe part I5 or vice versa, it will contactwith each of these parts simultaneously thus eliminating entirely or to a large extent vany arcing in making such passage.

The part 2l, however, is easily detached and replaced with a newppart as is also the part I6. The parts Il! and and electrically connected through the member I, no arcing takes place as the 2l being of the same polarity` current collector arately formed lug inserted in a cavity 33 and may be of metal or insulating material.

By constructing the end-of the body portion I,l

as shown and described, it is possible Whenever desirable to atta-ch the body member to other devices used in overhead trolley construction by 1forming a cooperating part on said device.

The member i6 is provided with a connecting part 34 to receive a conductor from the device to be operated, as for instance the operating coil of an electric switch. Since the member IG is insulatedifrom the trolley wire lli, current may be drawn through the said operating coil when the current collector 3i engages the member it. Having described-my invention others skilled in the art will recognize modincations which may be made and which may fall within the scope of my invention and, therefore, I wish to be limited only by my claims..
