2 Claims.

This invention appertains to new and useful improvements in platforms especially adapted for use by linemen on poles and towers.

The principal object of the present invention is to provide a platform which can be readily mounted and which will be sturdy and safe in use.

Another important object of the invention is to provide a platform of the character stated which is constructed in such a manner as to be adaptable to various shapes and sizes of poles and towers.

These and other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings Figure 1 represents a sectional view taken substantially on a line l-l of Figure 2.

Figure 2 is a side elevational view of the structure shown in Figure 1.

Figure 3 is a sectional view taken substantially on a line 3--3 of Figure 1.

Figure 4 is a sectional view taken substantially on a line 4-4 of Figure 3.

Figure 5 is a front elevational view of the platform, with the chain clamp removed.

Referring to the drawings, wherein like numerals designate like parts, it can be seen that the numeral 5 represents the platform proper preferably covered by rubber pads 6. Numeral 1 represents the head portion of the platform and this is preferably constructed of metal and bifurcated on a horizontal plane to afford the upper and lower furcations 8-9 spaced apart to accommodate the clamping chain I 0.

The pole or tower engageable end of the head 1 is of V-shape and stepped as at ll so as to accommodate girders, angle irons or round holes of various sizes. The burrs l2l2 on the forward corners of the head 1 are used when the platform is engaged with a pole, preferably wooden poles, that cannot be gripped by the stepped V-shaped out.

A bifurcated lug l3 on one side of the head I is intended to receive the T-member l4 at one end of the aforementioned chain ID. This is the anchoring means for one end of the chain, while the other end portion of the chain extends between the furcations 8 and 9 to connect to the screw shaft l5 at one end thereof.

This screw shaft at its opposite end portion extends through the boss IE on the same side of the head 1 with the lug l3. Numeral I1 represents a round nut engaged on the threaded shaft l5 and being rotatable against the boss I6 to feed the shaft l5 in forward or reverse direction. This nut I! has a handle 18 which has a yoke l9 embracing the nut I l and being pivotally connected thereto.

Obviously, by disposing the chain Ill around the tower member 20 and engaging the T I4 with the lug I3, the platform can be held until the chain is firmly clamped in position by feeding the nut I! inwardly on the shaft [5, thus drawing the shaft I5 through the boss l6 and pulling tightly on the chain I 0.

The head I is provided with a pair of outwardly extending upper legs 2l-2| and a pair of somewhat longer lower legs 2222. Between these upper and lower legs 22-22 and 2l 2| is disposed the forward portion of the platform 5 and bolt members 23 are disposed through the legs and platform for securely fastening the platform to the head I.

A pair of brace members 24-44 extend forwardly from the free end portions of the legs 22-22 and in downwardly diverged relation with 20 respect to the head I and are braced at their lower ends by the V-shaped pole or tower engageable member 25 which has its indented side stepped as at 26. The lower ends of the brace members 24 are provided with spurs 21 which are used in the same capacity as the spurs V |2-l2.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the inventionas claimed hereinafter.

Having described the invention, what claimed as new is- 1. A platform of the character described comprising a supporting structure having an upright engageable head portion, and a clamp chain mounted at its upright engageable end for embracing an upright and holding a support thereto, and a downwardly extending upright engageable brace on the support said brace including a horizontally elongated member, and spurs on the ends thereof.

2. A platform of the character described comprising a supporting structure having an upright engageable head portion, and a. clamp chain mounted at its upright engageable end for embracing an upright and holding a support thereto, said support being divided into a head portion and a seat portion said head portion provided with vertically spaced horizontally disposed leg members said seat portion having one end thereof disposed between said leg members and securing means between the leg members and the seat portion.
