This invention relates to apparatus for mountf guide pulleys and the connection of oneof the ing basketball backboards and has for an obcables to one of the telescopic rod supports ofthe ject to provide apparatus of this character adaptbackboard.

The backboard mounting apparatus comprisn A further object is to provide apparatus of this ingthe subject matter of this invention includes 2'0 character which will be formed of a few strong Y a pair of verticallydisposed-telescoping rods I3, simple and durable parts, which will be inexeach including an upper tubular rod Iland a pensiveto manufacture, and which will not easlower rod I5 slidable into and out of the upper ily get out of order. rod.

the ends, secured to the tube by strap rings 43.
'I'he brace frame comprises parallel side members 30, each formed of a pair of overlapping arms 3| and 32 of angular cross section. The upper arm 3I is provided with a cut-away portion 33 at its lower end, as best shown in Figure 1, which end is overlapped by the upper end of the lower arm 32. A pivot pin 34 is passed through the overlapping ends of the arms to permit elbow motion, as shown by dotted lines in Figure 1. The lower end of the lower arm is pivotally connected to the lower rod I of the respective telescoping rod I3 by a pivot pin 35. The upper end of the upper arm is pivotally connected by a pivot pin 36 to a flat head 3l formed on the end of a bolt 38, best shown in Figure '7. The bolt 31 is engaged through the wall 25 of the building to pivotally anchor the respective side member of the brace frame to the building. A pair of crossed braces 39, of angular cross section, are secured at the ends to the side members of the brace frame, as best shown in Figure 2, to reinforce the members against spreading apart.
The counterbalance .comprises an elongated tube 40, best shown in Figure 5, which is closed at both ends. The tube is provided with opening 4I in the top side through which sand or other ballast may be inserted in the tube to weight the tube, as best shown in Figure 1. The tube is provided with a pair of sheaves 42 near The counterbalancing weight is suspendedfrom the beams 23 by a pair of cables 44 which are passed through respective sheaves 42 and secured at one end to respective beams 23 by bolts 45. The cables are trained over respective sheaves 46 disposed between each respective pair of beams 23 and secured to the latter by a pair of bolts 41, as best shown in Figure 5. From thence, the cables 44 are trained downwardly through respective upper tubular rods I4 of the telescoping rods I3 and terminally connected to the upper ends of respective lower rods I5 by bolts 48, as best shown in Figure 4.
When the side members of the brace frame 3B are in full line position shown in Figure 1, the weight 40 has a tendency to pull upward the lower end of the lower arms 32.k This is resisted by the overlapping lower portion of the upper arms 3| so that the backboard I is rmly held in operative position. When the elbow joint is broken, as shown by dotted lines, the lower arms 32 will engage in the cut-away edges 33 of the upper arms 3l, at the limit of movement of the joint, so that the weight will hold the backboard raised to upper position above the proscenium. 26.
Bq now referring to Figure 4, it will be seen that a sleeve 49 is welded, or otherwise secured, to the upper end of the lower rod I5 of each telescoping rod I3. Also a sleeve 5U is welded, or otherwise secured, to the lower end of the upper tubular rod I4 of each telescoping rod. In case the cable 44 breaks the lower rods I5, carrying the backboard I0, will gravitate until the sleeves 49 engage the sleeves 5i! and prevent further gravitating movement. Thus the rods and backboard are prevented from falling to the floor of the stage in case the cables 44 break.
A pair of auxiliary safety cables 5I are secured at the upper ends to the beams 23 and at the lower ends to thel strap rings 43 to check the counter weight in case the main cables 44 break.
Since the operation of the parts have been described as a description of the parts progressed, it is thought that the operation of the invention will be fully understood Without further explanation.
