"ATTACHMENT non LADDERS.

Application filed. February 20, 1923. Serial No. 620,209.

To all whom it may concern: 1

Be it known thatv LyJosnrii COMEAU, a citizen of the United States, residing at Providence,in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Attachments for Ladders, of-which the following is a specification. 1

This invention relates to an attachment designed more particularly to be applied to a ladder used by linemen in repairing telephone cable wires and the like, and has for its object to provide, an attachment which may be readily applied to a ladder, the same beingprovided with a pair of hook-shaped arms whereby the upper end of the ladder may be adapted to engage an aerial wlre "such as used in telephone service, andfor other similar purposes, and to prov de a convenient support for the repalr men 1n operating upon a cable.

A further object of the invention is to so form the members of my improved attachment that they may be detachably connected together whereby when not in use the parts may be folded one upon the other into a convenient and compact bundle to be,

' used as a regular part of a linemans kit.

With these and other objects in view,.the invention consists of certain novel features of construction, as will be'more fully described, and particularly pointed out in the I appended claims.

In the accompanying drawings: Figure 1 is a perspective view illustrating my improved device-as applied to a ladder and as connecting the upper end of the ladder to a telephone wire.

Figure 2 is a detailed construction illustrating my improved device as applied to the upper end of a ladder. t

Figure 3 shows one of the sides of a ladder in section and a portion of one arm of my improved attachment as clamped to the side of the ladder.

Figure 4 shows the suspended seat detached.

Figure 5 shows the tool tray.

It is found in practice by telephone wire repair men, of advantage to provide a simple and practical ladder attachment whereby the upper end of the ladder may be connected to a cable supporting wire in such a way that the ladder cannot possibly be accidentally disconnected from the wires and at the same time hang a sufiicient distance from the wire soas not to interfere with the freedom of movement of the operator upon the wire; that is, the ladder should hang just far enough away from the wire so that a work man on the ladder will be within easy work ing reach of the wire to be operated upon so as to permit the workman to make the necessary repairs. Insome cases, a seat may be provided for the support of the operator when the Work is long and tedious. The following is a detailed description of one construction by which these advantageous results may be accomplished With reference to the drawings, 10 designates the two spaced-apart sidesof a ladder employed by linemen, which sides are connected by the usual rounds l1. Near the upper end of the ladder,'I have'attached the horizontally-disposed arms 12. One end threaded to receive the thumb nuts15 where.-.

by when the nuts are setup the arm 12 is quickly'and securely clamped to the-side of the ladder being preferably positioned just above one of the rounds 11 so that it is impossible for the arms to slide'downwardly even though the clamp should become slightly loosened. g Y

The outer end'of each of these arms is preferably formed slightly thinner than the clamp end thereof and is bent back upon itself as at 16 providing an elongatedhook with its end 17 turned slightly outwardly to permit engagement with the wire 18, and when this wire is engaged by the hooks of both arms the great length of the hook posiof each arm is drilled to receive the ends tively insures the, ladder from becoming inadvertently disconnected from the wire so as to insure the linemen against a fall by accidental disconnecting ofthe ladder from the wire.

In orderto further support the outer or hooked end of the arm, I have provided a stay rod 19 for each arm, the outer end of the rod being removably connected to the outer end of its arm 12 by means of a bolt 20 which passes through the arm and the rod and a nut 21 is threaded onto the freeend of the bolt to lock the rod to the arm. The

upper end of this rod is designed to lie against the outside surface of the side of the at 14, the threaded ends 22 of this clamp being provided with-clampnuts 23 -whereby this end is biound securely to the side .ofthe ladder thus firmly supporting the outer end of the arm against any weight which may be applied thereto.

In some instances when the job .toibe .done by the linemen, requires considerable time, it has been found convenient torsupportthe ends of a seat 24 on the opposite arms as illustratedin dotted lines in Fi gureQ, whereby the workmen may be comfortable while repairing a wire, :and in: other cases the "ends of a seat 31, as shown in Figure 4 may be suspended from these arms :as shown in Figures 1 and2, to support the body of a \worle man a convenient Working distance below the wire. To provide this suspending sup port fol'zthe seat, I have attached 'a' chain :25 to each corner of theseat 3-1 and the "free endot each chain provided with a book 32 to Lengagea corresponding hole 33in-itswarm. I have also shown .a tool carrying tray 26, see Figures 5 and 6, as supported at the ends :of the arms by brackets :27, each of which :is provided with a hook at -its=end to engage a :pin 28 'inithe arm, the same being within easy reach-of the wcrkman and the tray being provided at either end with a downwardly"turned lip :29 to catch over the sides of the brackets, "the upturned ends 30 "of which lock the tray in operative posi tion on theibrackets.

The members of my improved attachment are preferably made of comparatively thin light stock by which construction an extremely strong and durable construction as will be noted is formed and each of these parts may be readily disconnected from the side of the ladder and from each other whereby the members may be readily assembled in'a bundleto be carried me workman?s kit.

.Myl "improved iladder attachment is extremely simple :and practical in construc tion and byits usea lineman may readily apply it'to his ladder to support the ladder in exactly the right position sothat he may readily operate upon a cable with perfect safety -'andwhen he has finished it maybe quickly detached from'the ladder and compactly' folded for easy transportation,

The foregoing description is directed solely towards the construction illustrated, but I desirevit to be understood that I reserve the privilegeof resorting to all the mechanical changestowhich the device is susceptible, the invention'being defined and of the appended brace bar connecting the outerendof each arm with its ladder side, said arms cooperating to provide a support for a cross seat.

2. A ladder attachment comprising azpair of arms adapted to be removably clamped to the opposite side members of .a ladder, the outer end of each arm having an elongated reverse bend forming'a deep support engaging hook, an angularly disposed brace bar connecting the outer end of each arm with its ladder side, and :a cross seat supported on said arms all-of'which members the device are detachably connected to :a ladder and detachabl'y connected together whereby {they may} be folded into a compact bundle.

A ladder attachment comprising two hooked-shaped arms adapted to be clamped to the sides of a ladder, an angularly-disposed support for the outer end oi" each arm,

and seat suspended from said arms.

i. A ladder attachment comprisingsa'pair of hook-shaped arms adaptedto be clamped to the sides of-"a ladder, an -angularly disposed support for the-outerend of each arm, a seat suspended fronrand below ithe'plane of said arms, and 'a tool carrying tray also supported from said arms.

5. A ladder attachmentcomprising-a pair of arms having support engaging means adjacent their freeends, their oppositeends being adapted to be clamped to the sidesiof the ladder, an angularly-disposed support for the outer end of each arm, and a seat suspended from said arms.

In testimony whereof'I affix mysignature.
