An end fitting 43 is mounted. on the other end of each of the arms 41 and is provided with a square portion 43a. Each end fitting 43 is also provided with a cylindrical portion 43b which is disposed within the other end of the tubular member 41 and is retained therein by a rivet 44.

A clamping assembly 46 is mounted for rotational movement on each of the end fittings 43 and each includes a pair of

jaws

47 and 48. The jaw 47 carries a threaded stud 49 which extends through a bore 51 provided in the square portion 43a and which is retained therein by a wing nut 52. The other jaw 48 is pivotally connected to the jaw 47 by a link 53 which is pivotally connected to the jaw 47 by a rivet 54 and which is pivotally connected to the jaw 48 by a rivet 56. Each of the

jaws

47 and 48 is provided with an arcuate recess 57 which are adapted to receive a tubular elongate member as shown in broken lines in FIGURE 3. The jaw 47 is provided with a shoulder 58 which extends at right angles to the longitudinal axis of the jaw 47 and to the axis of rotation of the clamping means and is adapted to cooperate with the square portion 43a of the fitting 43 to provide cooperative means for retaining the clamping assembly 46 in the desired angular position. Each of the jaws 47 is provided with an inclined surface 59 at the other ends of the jaws which are adapted to be engaged by a bevelled or inclined surface 61 provided on a large knurled nut 62 threaded onto a threaded stud 63 carried by the link 53. A pin 64 is provided on a large knurled nut 62 threaded onto a threaded stud 63 carried by the link 53. A pin 64 is provided in the outer end of the stub to prevent accidental removal of the nut 62.

Means is provided for stabilizing the umbrella 17 after it has been mounted in the umbrella holder 16 and consists of a plurality of elongate flexible elements such as ropes 66. Each of the ropes has one end tied about the stays 19 above the point where the arm 23 is connected to prevent the rope from sliding downwardly on the stay. The other end of the rope is secured to an appropriate part of the manhole guard rail 11 as shown particularly in FIG- URE 1. As can be seen from FIGURE 1, four of such ropes 66 are provided to secure at least four points of the umbrella 17 to the manhole guard rail.

A boss and hook assembly 68 is provided on each of the stays of the umbrella 17 and consists of a boss 69 which is slidably mounted upon the stay 19. A book 71 is threaded into the boss and engages the stay 19 to hold the boss 69 in a predetermined position on the stay 19. The boss and hook assemblies 68 are utilized for carrying a pair of curtains 72.

The curtains 72 can be formed of a suitable material such as a vinyl-coated nylon which is yellow on the outside and which has a white interior. A plurality of spaced grommets 73 are provided on the top of the curtain and are adapted to be hooked onto the hooks 71. Metal stiffeners 74 are also provided on the upper ends of the curtains 72 and are sewn into hems provided on the upper ends of the curtain. Suitable fastening means are provided on the sides of the curtain to facilitate fastening the two curtains together in the manner shown in FIG- URE 7 and consists of strips 76 provided on both side edges of each of the curtains which extend substantially the entire length of the curtains. One of the strips 76 is provided on the inside of one side edge, whereas the other of the strips 76 is provided on the outside of the other side edge of the curtain. The strips are preferably formed of Velcro in which one of the strips carries hooks and the other of the strips carries eyes to facilitate the fastening together of the curtains. In addition, each of the curtains 72 is provided with a lower transparent panel 78 formed of a suitable material such as vinyl.

In using the assembly thus far described, the manhole guard rail 11 is first set up so that the support elements 12 are spaced apart in the manner shown in FIGURE 1. Thereafter, the umbrella holder 16 is taken and the thumb screws 33 and 38 are loosened. In addition, the large knurled nuts 62 are also loosened. The wing nuts 52 are then loosened and the clamping assemblies 46 are shifted on the square portions 43a so that the shoulders 58 engage the bottom extremities of the square portions 43a and so that the clamping assemblies are in alignment with the arms or members 41. Thereafter, the wing nuts 49 are tightened. The clamping assemblies 46 are then shifted so that the intermediate portions of the support elements 12 are engaged by the clamping assemblies 46. Thereafter, the large nuts 62 are tightened so that the bevelled surfaces 61 engage the inclined surfaces 59 provided on the

jaws

47 and 48 to spread the same apart and to urge the other extremities of the

jaws

47 and 48 into clamping engagement with the support elements 12 to support the umbrella holder upon the support elements. The bracket 31 is then shifted so that the hole 32 in the bracket is extending vertically. At this time, the thumb screws 38 are tightened to cause the

serrations

36 and 38 to engage each 4 other and 'to hold the bracket 31 in the desired position with respect to the arms 41.

Next, the umbrella is opened and the umbrella pole 18 is inserted into the hole 32 and secured therein by tightening of the screw 33. Then the ropes 66 secured to the stays are tied to the guard rail 11 at the four opposite corners of the guard rail to hold the umbrella securely in place. The assembly thus far described can be used in a number of applications. For example, it can provide the necessary shade for the workman in the man-hole and it also can provide some protection from rain. However, if additional protection is desired, the curtains 72 can be installed by placing the grommets 73 on the hooks 71 with the stilfeners 74 disposed between the hooks 71. After both curtains have been hung upon the hooks 71 carried by the umbrella 17, the two curtains 72 can be fastened together by pressing the Velcro strips 76 against each other. With the assembly in this condition, it can be seen that complete protection is provided from wind, rain and sun. If desired, the workman can only use one of the curtains.

The assembly is very advantageous in that it has the necessary stability and will withstand any ordinary winds encountered. It will provide the necessary protection from the weather as, for example, sun, wind and precipitation. The transparent panels 78 provided in the curtains 72 make it possible for the workman when he is emerging from the manhole to see whether trafiic is approaching in the event the manhole is located in the street. The transparent panels 78 also ensure that there is adequate light for the manhole. The bright coloring provided on the curtains 72 ensures that the entire assembly is visible to an approaching motorist. The white interior provided for the curtains ensures that light having the normal wavelengths will be seen in the manhole so that it does not alfect the workman in operations where color coding is required as, for example, in cable splicing.

Another embodiment of the invention is shown in FIGURE 8 in which the support means is in the form of a rectangular platform 81. The support means also includes an elongate support element in the form of a strand or messenger 82 and ropes 83 which are secured to the four corners of the platform 81 and removably hooked by books 84 onto the strand 82. The umbrella holder 16 which is identical to that hereinbefore described is utilized in connection with the platform 81. However, in this case, the clamping assemblies 46 which form a part of the umbrella holder 16 are first released by loosening the wing nuts 52 and the clamping assemblies are rotated through 90 and the wing nuts fastened so that the clamping assemblies extend in a direction which is at right angles to the longitudinal axis of the members 41. In addition, the thumb screws 33 and 39 are released and the arms 41 are positioned so they extend substantially at right angles to the bracket 31 and are in general alignment with the strand 82. The clamping assemblies 46 are then secured to the strand or messenger 82 in the manner in which they were attached to the support elements 12. The umbrella pole 18 is placed in the hole 32 and fastened there in by the thumb screw 33. The ropes 44 carried by the umbrella are then secured to the four opposite corners of the platform 81 to prevent tipping of the umbrella. With this arrangement it can be seen that an umbrella can be readily provided for a workman who is working in the air and who is performing certain operations such as splicing a cable 86. In addition, it should be appreciated that, if desired, curtains 72 of the type hereinbefore described can be hooked onto the umbrella 17 to provide additional protection to the workman upon the platform 81.

It is apparent from the foregoing that there has been provided an assembly which is particularly useful in providing protection to a workman and an umbrella holder which is utilized in the assembly to support the umbrella. The assembly and the umbrella holder are of a type which can be readily set up and put into use. They are also ones which can be readily and economically manufactured.
