The inwithl horizontally projecting studs 18, said 100 is provided with a head which holds the bolt against 'endvvise movement in one direction. Brace members 21 are provided near their ends with holes 22 so as to engage over the studs 18. Eachy brace memberl 21 connects adjacent diagonally opposite studs 18 longitudinally of the scaold, as clearly shown in Figure 2. The brace members 21 are prevented from sliding off of the studs 18 by Cotter pins 23, or their equivalents, insei-ted through vertical holes 24 in the studs 18. The system of brace members 21 may be used for the outer side only of the scaffold and the inner side of the scaffold may, if desired, be anchored to the structure, along side of which the scaffold is placed. This is done by providing fastening members 25, each of which forms a loop 26 around one of the standards 8. Each fastening member 25 also comprises a pair of legs 27 projecting from the loop 26. The member 25 is applied to the standard by bending it around the same and the legs 27 are then secured to one of the Window frames B, or other suitable member,
' of the structure A. In this instance, the legs 27 are secured in place by nails 28.
A modification of the joint members is illustrated in Figures 5 and 6 and the elements that correspond in function with those above described are. indicated by the same reference character With the addition of the letter af In this instance, the slot 16 is omitted and the body 15a is provided With a fork 29 and the opposite members of said forli are provided With vertically alined holes 30 to receive a pin or bolt 31. r[he pin 31 may have a head 32 to prevent it dropping out of the holes 30. `When this form of joint member is employed, the associated cross member 10a is provided near each end With a hole 17a so that, when the cross member is inserted in the slot 16a of the fork 29, the pin 31 can be inserted through the holes 30, 17 so as to secure the cross member to the joint member.
I claim:
A scaffold comprising standards, joint members mounted on the standards and provided with horizontally extending slots, and cross members engaging in the slots and provided with gains to receive the bottom walls of `the slots.
