This invention relates to an apparatus for piece of timber is now inserted edge on into erecting staging, platforms and the like. the space formed between the saw-like edges One object of the present invention is to of the plates 7 and g and is securely clamped provide a simple form of trestle member 00- therein by reason of the teeth on the said cupying a minimum of space. A further obmembers penetrating the timber. The whole ject of the present invention is to provide a now forms a strong and rigid support for the trestle member which can be utilized for suphorizontal platform and the heavier the dead porting working platforms by merely insertweight of the latter the tighter the timber ing pieces of timber to serve as legs in sockets between the edges of the plates 7" and 9 will provided for the purpose, so that no adjusting be clamped. Obviously, any number of deor s racing members are necessary. vices made so 'ording to the present invention One form of device made according to the may be utilized for any working platform. present invention is illustrated by way of eX- By the use of the present invention horiample in the accompanying drawings where- Zontal working platforms are quickly erected in and dismantled, and when dismantled they Fig. 1 is an elevation; take up very little space when being trans Fig. 2 is a plan; and ported.

A trestle head comprising two base Referring to the drawings the device complates hingeably connected together and an prises two j aw portions a adapted to be hingeupwardly extending jaw portion fixed to ably connected in co-operative relationship each base plate each jaw portion consisting by a pin Z) which passes through channels 0 of two vertical olatcs in spaced relationship formed in base plates (Z by stamping away and each base plate having a portion extendthe material at the edges of the plates (Z to ing upwards between the vertical plates conform tongues which are then rolled up to stituting the jaw portions and formed so as to form the channels a. Each jaw a is formed constitute a socket adapted to receive timberof two vertical plates 7 and g riveted on to constitute the trestle legs. either side of a socket portion 6. The latter 2. A trestle head comprising two spring is stamped from one piece of metal the top pressed base plates hingeably connected toand sides being folded inwards as shown at gether and an upwardly extending aw porh, 72, Z, to form sockets m (see Fig. 3), the tion fixed to each base plate each jaw portion bottom portion (Z being bent outwards on the consisting of two vertical plates in spaced other side to form the base plate (Z. The relationship, and each base plate living a top it is bent so that spaces 29 are formed beportion ez-ztendin upwards between the vert 'een the top it and the jaw portions a. T he tieal plates constituting the jaw portions and opposing edges of the side members 7 and 9 formed so as to constitute a socket adapted are of saw-like formation for the purpose to receive timber to constitute th trestle legs.

In use when it is desired to erect the horizontal working platform a piece of timber is inserted into each of the sockets m and the pieces of timber are supported on the ground, the timbers being inclined to each other and being wider apart at the bottom than at the top, thus forming a firm support.
