7 Claims. (01. 36-60) This invention relates to linemans pole and tree climbers, having the usual spur or spike carried by a curving foothold and-leg shank, and the object of this invention is the production of a climber having special construction and arrangement of parts, particularly with relation to an adjustable leg at the top of the shank adjustable to length of climbers leg and a removable spur member suitably secured to the lower portion of the device.

The preferred form of this invention is illustrated in the accompanying drawing, of which Fig. 1 represents a side view of all parts assembled. Fig. 2 is a front or face view of the adjustable leg. Fig. 3 is a rear View of the leg plate. Fig. 4 is a cross-section of the flange members or T iron forming the shank, the section being taken on the broken line 4-4, of Fig. 2. Fig. 5 is a cross-section of the leg plate and slide housing plate showing the flanged members in section therein. Fig. 6 is a front view of the pivotal link keeper for securing the head end of the spur. Fig. 7 is a sectional view of the lower part of the composite shank, showing the removable spur therein, and the position of the pivoted keeper link securing the head of the spur. Fig. 8 is a cross-section of the lower portion of the shank which receives the foot of the wearer, and illustrated the inner flanges constituting a groove or seat for the spur.

Other than Fig. 1, all figures are full size.

Throughout the drawing and description the same number is used to refer to the same part.

Considering the drawing, the shank of the climber is made up of the twin flanged members 1 and 2 united or may be one T iron unit with the projecting flanges 4 and 5 in contact as shown in Figs. 4 and 5, the latter section being taken on the broken line 5--5 of Fig. 3.

Fig. 2 shows a front view of a flat piece termed for the purpose of this description the leg plate 6. The edges 7 and 8 of the plate are turned over as best shown in Fig. 5, upon a second plate 9 which is given a raised portion lengthwise to movably receive the upper portion of the shank. The

raised portion or slide housing is marked 10. The back or fln of the plate 9 marked 11 in Fig. 1 has a longitudinal slot 12 for the usual leg strap of the wearer not shown. Holes 13 are made through the fin of the plate 9, and through the meeting flanges 4 and 5 of the flanged members 1 and 2, and a cotter pin 14 may be passed through either hole 13. The leg plate 6 can be thus adjusted longitudinally of the shank which is made longer or shorter thereby as will be readily understood.

Considering Fig. '8, numbers '15 and 16 mark widened lower parts of the flanged members, and the inner and slanting flanges 17 and 18 are'combined to form a groove or seat for the spur 19, curved in correspondence with the foothold part of the shank. The spur point is :marked 20. On the left hand side in Fig. 7 are shown two pins 21 and 22 fast in-the shank, and a third pin is carried by the end of the shank at the right side of Fig. 7. The spur has a hookhead 24 arranged to engage 'the pin 23, and notches '25 and 26 to engage the pins 22"and 21. As best shown in Fig. 6, the end 27 of the lower shank portion 15, andthe end 28 of the shank part 16 carry the pin 23 that engages the spur hook head 24. 7.0

In Fig. 7 it will be understood that the hook head 24 of the spur engages the pin 23 between the ends marked 27 and 28 in Fig. 6, and a space 29 is shown in Fig. 6 between those ends for the introduction of the head 24. A keeper link 30 swings with the arrow indicated, and it has an off-set back rib 31. This construction leaves a space between the link and the rib for the usual straps common to pole climbers. The rib and the link at the bottom are joined by an integral cross-head 32, and it is this feature that bears upon the head 24 to hold the spur.

In the operation of removing the spur, if the link is swung to the right as indicated in Fig. 7 the head of the spur is free, and the spur may now be passed outwardly between the two pins 21 and 22 thereby freeing the spur from all the pins. When the spur is in position as illustrated in Fig. 7 and the usual strap, not shown, is passed through the space 33 and secured around the ankle of the wearer, the keeper link cannot swing, and the spur is held absolutely against displacement. It will be understood that the spur may be removed to sharpen its point when needed or different length spurs may be carried to replace the spur on the climber as per requirements of the operator in climbing different grades of trees or poles. This invention is not limited to the exact shape or size of any element of the combination, as the individual features may clearly be made in difierent forms.

Having now described this invention, I claim:-

1. In a linemans climber, the combination with a shank portion comprising twin flanged members secured together or a T iron unit forming the shank of the climber, said shank portion having a lower part fashioned to receive the foot of the wearer, a removable spur engaging said lower part of the shank, the said members having inner flanges formed to seat the said spur, and means for securing the spur.

2. In a linemans climber, the combination with a shank portion comprising twin flanged members secured together or a T iron unit forming the climber shank, of an adjustable leg plate, means for securing said plate at the upper end of the shank, a removable spur, said shank portion having a lower part constructed to receive the foot of the wearer, andmeans for securing the spur to the said lower part of the shank.

3. In a linemans climber, the combination with a shank portion, said shank portion having a lower part fashioned to receive the foot of the wearer, a removable spur engaging the lower part of the shank, and means provided with an opening for the passage of a strap and constructed to secure the spur in detachable relation to the said lower part of the shank.

4. In a linemans climber, the combination with a shank having a lower part fashioned to receive the foot of a wearer, of a removable spur constructed to correspond in curvature with the said lower part of the shank and to engage the shank in detachable relation, means for securing the spur comprising a pivoted keeper having an opening for the passage of a strap.

5. In a linemans climber, the combination with a shank having a lower part fashioned to receive the foot of a wearer, of a removable spur constructed to correspond in curvature with the said lower part of the shank and to engage the shank in detachable relation, the said spur having at one end spaced notches, the said shank having spaced pins for engaging said notches, said spur having at the other end a hook head, said lower part of the shank having near its end a pin arranged to engage the said hook head of the spur, and means for securing the head of the spur to the end pin of the shank.

6. In a linemans climber, the combination with a shank comprising twin flanged members secured together, the said composite shank having a lower part fashioned to receive the foot of the wearer, of a removable spur constructed to correspond in curvature with the said lower part of the shank and to engage the shank in detachable relation, said spur having at one end spaced notches, said shank having spaced pins for engaging said notches, said spur having at the other end a hook head, said lower part of the shank having near its end a pin arranged to engage the said hook head of the spur, and means for securing the spur.

7. In a linemans climber, the combination with a shank having a lower part fashioned to engage the foot of the wearer, of a removable spur, said shank and spur having mutually engaging devices for securing the spur at one end of the spur, said spur having a hook head at the other end, said lower part of the shank having near its end a pin arranged to engage said hook end of the spur, and means pivotally carried by said end pin of the shank and provided with a strap opening and having a cross-head adapted to engage and release the hook head of the spur.
