To all whom t may concern.'

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 Catenary Hangers, of which the following is a Specification.

This invention relates to'catenary hangers designed especially for use in connection with trolley wires, but applicable to other electrical conductors, and to other wires or cables that are suspended in substantially horizontal position.

The invention consists of the novelty in the construction, combination and arrangement of the several parts.

In the drawings Figure 1 is a side elevation of a hanger constructed in accordance with the principles of this invention; F ig. 2 is a side view ofthe hanger with parts shown in section; Fig. 3 is a perspective of one of the wire clamping jaws; Fig. 4 is a perspective of an end engaging member of the suspension device, and Fig. 5 is a perspective of the two ends of the preferred form of suspension device.

In a catenary suspension system for trolley wires, it is the common practice to provide a messenger or suspension cable supported at various points along the line, which hangs between the points of support in a catenary curve. The conductor or trolley wire is suspended from the messenger by a series of hangers spaced at comparatively short intervals along the line, and in order to support the conductor in a substantially straight line, the hangers are made of differ'- ent lengths to compensate for the curve in the messenger wire. In order to permit the trolley wire to rise slightly when the trolley wheel or collector passes along the trolley wire, a loose suspension member is provided which rises with the trolley wire without displacing the messenger wire. l

The present invention relates to a trolley wire hanger of this class, in which one of the arms of the hanger may be displaced with respect to the other parts to allow the suspension member of the hanger to be placed over the messenger wire without disconnecting or displacing the other parts of the hanger. This construction is particularly adapted for use by linemen who usu- Be it known that I, GLENN HENRY Bonus,v

ally work at the top of a tower, orin malring the installation in Cold weather, for the reason that it is sometimes diflicult to start a nut on a bolt, and much time is taken in adjusting and fastening together the parts of other hangers. With the present construction the parts are never displaced, and

all that it is necessary for linemen to do is to loosen the nut, remove one of the arms of the suspension member and hook 1t over the messenger wire, whereupon it may be replaced and all of the parts tightened without actually displacing them.

In the drawing the reference numeral 1 designates generally a suspension member having parallel arms, one of which is formed with an eye 2, and the other with a projection 3 in the form of a "l". rIhe Wire holder consists of a pair of jaws 4, each formed with a wire-engaging groove 5 at the lower end, and with a groove 6 and a projection 7 coperating with the other jaw at the top thereof. Intermediate the top and 4bottom of the jaw it is formed with a perforation 8, through which a headed bolt 9 is inserted, the bolt being first inserted through the eye 2 of the suspension member 1. A member l0 is provided with a perforation 11, adapting it to be inserted on the bolt 9 on the side ofthe wire clamp opposite the eye 2, and this member is formed with a notch 12 adapted to form a seat for the headed eX- tremity 3 of the suspension member l. rll`he notch 12 has a curved extension 13 to accommodate the extremity of the suspension member 1 above the head 3. The notched portion of this member 10 is preferably cut away at 14 as clearly shown in Figs. 2 and 4, so that the member 10 need not be loosened the full width of the headed extremity 3 of the suspension member in order to insert or disengage the head 3 from the notch 12. A nut 15 is provided for the threaded end of the bolt which bears directly against the member 10. With this construction it is obvious that by simply loosening the nut 15 on the end of the bolt 9, the headed end 3 of the suspension member 1 may be inserted or removed from the groove 12 without displacing any of the other parts of the hanger. The eye 2 of the suspension member has a fixed engagement with the bolt, and the jaws of the clamping member 10 are both perforated so that the bolt can be inserted through them. rlrherefore the parts are not relatively disengaged, even though the headed arm of the suspension member is sprung outwardly, as shown in Fig. 2, to such an extent as to allow a messenger wire to be inserted or removed from engagement with the suspension member.

What I claim is:

1. The combination with a trolley wire holder, of a suspension member for said holder having an eye at one end for permanent engagement and a projection at the other end for displaceable engagement with the holder.

2. The combination with a trolley wire holder, of a suspension member for said holder having two suspension arms one of which is formed with an eye and the other with a projection, and means for securing the holder and the arms of the suspension member together but adjustable to permit the separation of the arm with the projection from the holder.

3. The combination with a trolley wire holder, of a suspension member for said holder having two suspension arms one of which is formed with an eye and the other with a projection, and a bolt insertible through the eye member to secure the holder and the arms of the suspension member together.

4. The combination with a trolley wire holder, of a suspension member therefor having parallel arms one formed with an eye and the other with a projection, a bolt inserted through the eye and a nut coperating therewith to fasten this arm and the wire holder together, and a separate member to releasably engage the other arm of the suspension member.

. 5. The combination with a trolley wire holder, of a suspension member therefor having parallel arms one formed with an eye and the other with a projection, a bolt inserted through the eye and a nut coperating therewith to fasten this arm and the wire holder together, and a separate member also engaged and fastened by the nut and bolt to releasably engage the arm of the suspension member which has the projection.

6. The combination with a trolley wire holder, of a suspension member therefor having parallel arms one formed with an eye and the other with a projection, a bolt inserted through the eye and a nut coperating therewith to fasten this arm and the wire holder together, and a member having a notch-to engage the projection on the arm of the' suspension member and adapted to be held by the bolt and nut against the wire holder for releasably holding this arm when the nut is tightened on the bolt.

7. The combination with coperating wire clamping jaws, of a suspension member having parallel arms, one end formed with an eye and the other with a projection, a member having a notch to engage the projection, and a fastening device to fasten the jaws, the arm with the eye, and the notched member together, the arm with the projection being insertible and removable from engagement with the notched member by loosening the fastening device but not displacing the other members.

8. The combination with cooperating wire clamping jaws, of a suspension member having parallel arms, one formed with an eye and the other with a T-shaped head, a member having anotch to engage the head, a bolt insertible through the said eye, the clamping jaws, andk said notched member, and a nut threadedv on the bolt to hold the parts together and the aws in clamping relation, the headed end of the suspension member being insertible and removable in the notch by loosening the nut and without removing the nut from the bolt or otherwise disengaging or separating the other members.

9. The combination with a trolley wire holder comprising a clamping bolt and nut, of a suspension member having parallel eX- tremities one formed with an eye disposed on one side of the holder through which the bolt is inserted, and the other formed with a projection, and a member pressed by the nut against the other side of the holder having a notch to engage the projection with a eut-away portion adjacent the notch so that the nut may be loosed less than the thickness of the suspension member to release the projection.

10. The combination with a suspension member having parallel arms and wire clamping jaws, of adjustable means to fixedly engage one of the arms and said jaws, a notched member also engaged by said means adapted t0 releasably engage the other arm of said suspension member and having a cut-away portion adjacent said notch to engage and disengage the said arm without moving said adjustable means the full width of the said releasable arm.

11. The combination with a trolley wire holder, of a suspension member for said holder having means at one end for permanent engagement, and a projection at the other end for displaceable engagement with the holder.

12. The combination with a trolley wire holder, of a suspension member for said holder having parallel suspension arms one of which is formed up for permanent engagement with said holder and the other of which is displaceably engageable by the holder.

13. The combination with a trolley wire holder, of a suspension member having two suspension arms one of which is formed tWo subscribing Witnesses, on this 6 day of with an attaching means and the other with Nov. A. D. 1915. a projection, and a bolt engaging the attaching means to secure the holder and the other GLENN HENRY BOLUS' arm of the suspension member together. Witnesses:
