' Application file d. May 8,

i This invention relatestotools or accessories intended for use by telephone and telegraph provision of novel climbing irons by means linemen, and has for its object the 1 of which a linemanmay readily climb poles for the purpose of making repairs,

ments or the like.

An important object is the provision of climbing irons which are simple and inexpensive to manufacture, easy which to adjust, and

are, moreover, of such construction that the parts thereof may be very readily disassembled for convenience in transportation or storage.

Anotherob ect s to provide climbing irons which, most p when in applied position, will be ositive in their holding action so that there will be no probability or possibility or the user slipping and falling.

Another obj'ectis to provide a structure or device of this character which will be simple and inexpensivem manufacture, positive in action, efficient and durable in service, and a general W1th the above and improvement in the art.

other objects and adantages in view, the invention consists in the novel construction elements to be hereinafter morev fully described and claimed, and illustrated 1D. the

accompanying drawings,

in which Figure 1 1s a plan vlew ofone of the climbing irons.

Figure 5 is a perspective view of one-of the foot or shoe engaging members, and

Figure 6 is on the a detail in cross section taken line 66 of Figure 1.

Referring more particularly to the drawings,

- iron I have shown each of the climbing devices for each foot ascomprising a substantially quarter circular bar member 10 formed of iron,

steel'or other suitable material and provided with a plurality of spurs tratingly engaged shaped and arrangedas to be penewithin a pole or the like to be climbed by the user. Associated and ted with each of these members is a foot piece 12 which may be convenientlyv formed as a casting or stamping and which includes the plate portion 13provided at its ends with purpose to be.

carries an adjusting buckle 25 by means of which connection may bemade about the 1 foot of the user regardless of the size of the foot or the shoe.

In the operation of the device, it will be seen that when the user wishes to apply one of the devices to his foot, the foot piece is engaged with the slidably engaging the housing member 16 thereon, and when the proper position is ob-, tained the spring pressed pin or plunger 18 will engage within the recess or socket 20, thereby holding the foot piece firmly with respect to the arcuate bar. The operator The strap member 2a arcuate member 10 by then places his foot upon the member 12 and secures the strap 22 over hisinstep by means of the buckle .25. clear that one of the devices is placed on each foot. After thedevices are placed in position in this manner and secured as indi: cated, it is obvious that the lineman or other person thus equipped may easily climb a pole in the well known'manner, the prongs or spurs 11 biting into the pole and providing an adequate grip thereon so as to prevent any possibility-of slipping or fall ing. W hen use of the device is not desired,

it is clear that the pin 18 may be retracted by pulling foot piece member 10 stored within a tool box or other receptacle. It is believed that the construction, operation and advantages will be readily apparent to one skilled in the art without further explanation,

upon the head thereof and the It is of course disassembled with respect was so thatthe parts may be easily While I have shown and 'described the v preferred embodiment of the invention, it

should be understood thatI reservethe right to make suchchanges in the' forin, constructionand arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claim.

Having thus described the invention, I claim In a climbing iron of the character described, an arcuate bar provided at its concared side with penetrating prongs, and at taehing means for said bar comprising a foot piece of plate-like form provided at one end with an upstanding ear and prorided in spaced relation to its other end with a similar upstanding ear, said ears being provided with elongated slots, a fool: engaging strap structure engaged with the slotted ears, one end of said plate member being prolonged beyond the second named ear and formed to provide a housing slidably receiving one end of said arcuate bar, said end of the bar being formed with :1 recess and with an inclined notch leading from the end toward said recess, an enlarged guide portion on said housing, a spring located within said enlarged guide portion, and a pin slidabl mounted within said enarged guide portion and normally urged by said spring doii'nwardly for engagement within the recess in said bar, the notch in Ffiltl bar acting io ell'ect retraction oi the pin when the bar is inserted within the housing.

In liefitiniolrx whereof I allix ture.
