' R. c. LUCKINS SEALING DEVICE Filed Oct. 10, 1938 A iiorneys Patented Aug. 22, 1939 UNITED STATES PATENT OFFICE 2 Claims.

My invention relates to improvements in scaling devices for use by linemen in climbing poles.

The invention is designed with the particular purpose in view of providing a simply con- 5 structed, inexpensive apparatus adapted to frictionally grip a pole under step by step manipulation thereof so that metal poles may be quickly and safely climbed and also wooden poles without the use of mutilating spikes and unreliablesafety belts so-called.

To the accomplishment of the foregoing, and subordinate objects presently appearing, a preferred embodiment of my invention has been illustrated in the accompanying drawing, set

15 forth in detail in the succeeding description, and

defined in the claims appended hereto.

In said drawing:

Figure l is a view in rear elevation of the preferred embodiment of my apparatus applied to a 20 pole.

Figure 2 is a view in side elevation, and

Figure 3 is a view in transverse section taken on line 33 of Figure 1 looking in the direction indicated by the arrows and drawn to an enlarged 25 scale.

Referring to the drawing by numerals, the illustrated embodiment of my invention comprises as the basic elements thereof a pair of climbing irons I and 2 of inverted V shape adapted for 30 location upon opposite sides of the pole 3 and each comprising a laterally extending upper ledge 4 and a pair of downwardly divergent rod-like legs 5 depending from said ledge, the legs each being provided with an upper and a lower eyelet 35 end 6 and 1 and each ledge 4 having suitably secured thereto an upwardly arching stirrup 8 preferably of semi-flexible material such as leather.

The legs 5 are secured together by a pair of 40 ropes 9 and I0 trained through the eyelet ends 6 and I and across opposite sides of the pole 3 intermediate the irons, said ropes being coupled together all in a manner now to be described. One rope 9, for instance, is trained through the 45 lower eyelet ends I of one iron I then around one side of the pole 3, through the upper eyelet ends 6 of the other iron 2 and with the free ends thereof connected to a coupling ring II and a snap hook I2, respectively, forming the before- 50 mentioned coupling. The other rope I0 is trained through the lower eyelet ends I of the other iron 2, then around the opposite side of pole 3, and then through the upper eyelet ends of the other iron I with its free ends similarly connected to 55 said ring II and snap hook I2, respectively. As

will be seen, the ropes 9 and I0 are diagonally arranged, relatively, against the pole upon opposite sides thereof and intermediate the irons I and 2 for frictional engagement with opposite sides of the pole 3, and the legs 5 of said irons 5 are disposed upon opposite sides of said pole obliquely to facilitate frictional engagement of the legs with the pole. Obviously, the ropes 9 and ID will permit step by step movement of the irons I and 2 alternately and relatively upwardly 10 and downwardly. The legs 5 of the irons I and 2 are semi-flexible and light to bend under pull exerted thereon by said pairs of ropes and grip the pole 3.

Referring to the use of the described invention, two sets of the devices are applied to the pole one above the other, in a manner which will be obvious, for the linemans hands and feet. The lineman now mounts the lower pair by inserting his feet into the stirrups and on the ledges 4 and grips the ledges 4 or stirrups 8 of the upper pair. The irons I and 2 of each pair are then manipulated upwardly, step by step as occasion may require by movement of the hands and feet, the ropes 9 and I0 and the irons of each pair gripping the sides of the pole so that backward slipping is prevented and in a manner which will be manifest. Although the invention contemplates using two sets of the described devices, said sets being duplicates, a description of one will suffice for both.

The foregoing will, it is believed, suffice to impart a clear understanding of my invention without further explanation.

Manifestly the invention, as described, is susceptible of modification without departing from the inventive concept and right is herein reserved to such modifications as fall within the scope of the subjoined claims.

What I claim is:

1. A pole scaling device comprising a pair of climbing irons adapted to be disposed upon opposite sides of the pole, respectively, and each including an upper end stirrup and a pair of downwardly divergent rod-like legs having upper and lower eyelet-like ends, respectively, and means to connect said irons together comprising a pair of ropes each loosely extending through the lower eyelet ends of one iron and the upper eyelet ends of the other iron and across. the opposite sides of the pole in diagonal relation each with respect to the other, the legs of said irons being semi-flexible to bend under pull exerted thereon by said pairs of ropes and grip the pole.

2. A pole scaling device comprising a pair of climbing irons adapted to be disposed upon opposite sides of the pole, respectively, and each including an upper end stirrup and a pair of downwardly divergent rod-like legs having upper and lower eyelet-like ends, respectively, means to connect said irons together comprising a pair of ropes each loosely extending through the lower eyelet ends of one iron and the upper eyelet ends of the other iron and across the opposite sides of the pole in diagonal relation each with respect tothe other, said ropes being detachably connected together on one side of the pole, the legs of said irons being semi-flexible to bend under pull exerted thereon by said pairs of ropes and grip the pole.
