v Patented Jan. 7, 1930 PATENT OFFICE GEORGE CORN'UELLE, F CINCINNATI, OHIO BRICKLAYERS SGAFFOLDING Application filed September 30, 1827. Serial No. 223,188.

My invention relates to provision of suitable scafiolding for use by brick-layers in erecting walls, which fully satisfies requirements for rapid and accurate work, with the elimination of many tiresome movements, I and confusion of materials which is the result of the use of scaffolds at the present time.

In laying brick in a wall, it is always advantageous for the layer to see over the top of the work he is doing, so that he can line the Wall both inside and outside. In the usual practice of laying, the brick-layer has his brick, tile and the like dumped on the floor and builds his wall up to around five or six feet. He then calls for a scaffold on which the bod-carriers dump thebrick, mortar, tiles and the like, and he mounts the scaffold and works up to the-ceilingof a room, from the scaffold, again reaching above his chest with brick, if the wall is of normal height, and the scaffold not too high for the hod-carrier to dump his brickthereon.

The hod-carrier, in having to dump the brick on the top of the scaffold, stands on the floor and has to spill out the materials in the hod onto the scaffold, thus making a scattered pile, mingling brick and tile, and making it part of the bricklayers work to separate his materials, while laying them.

According to'iny invention, a scaffold is provided in which there are two stages or runs on which the brick-layer can work, preferably so arranged that the board on which the brick-layer stands is shifted up as the Wall gets higher, and supports at a high level may be swung into place to support it, Without delay in working time. When the wall has reached waist high, the brick-layer calls for the scaffold, and has the materials dumped on top of it, and standing on an intermediate run, lays the wall up to the top of the scaffold, at all times seeing over the wall to the outside thereof. He then mounts to the top of the scaffold and continues his work with his materials at hand.

By the use of my novel scafi'old, the number of bricks per day which are laid by the usualbrick-layer, are increased very materially without apparent effort on the bricklayers part, which is a great saving, and furthemore, the outside of the Wall can always be readily observed as the work proceeds.

I accomplislrmy objects by that certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed.

In the drawings Figure 1 is a plan view of a scaffolding showing the mortar board supports in re-- tracted position. v

Figure 2 is a detail perspective view showing the preferred type of mounting for the mortar board supports.

Figure 3 is a side elevation showing one of the scaffolding units.

I have shown a scaffolding. in which there are two assemblies of upright supports or frames which are supported with lateral braces, but it will be within the 'scope of my invention to if desired.

The scafloldingis formed oftwo frames composed of substantially spaced vertical pieces 1 which are secured together with diagonal braces'2 nailed or screwed thereto. A permanent run board support is indicated at 3 on which run boards 4 extending across be tween the horses are usually disposed for the brick-layer to stand on. The run board support is formed by extensions of the horizontal braces 5 which are nailed to the uprights. Extending across between the vertical supports I secure, as with nails, the cross braces 6. On the cross braces or on the upper part of the frame I'have provided iron bands 7 in which the top sliding supports 8 are mounted.

The provision of the top sliding supports for either a series'of mortar boards or run boards suchjas are indicated at 10 constitutes the essence of my invention, and the particular scaffolding structure which has been described may be otherwise varied.

The scaffolding shown is particularly adapted to normal wall construction. It will allow a brick-layer to build a wall of nine or more feet without requiring any additional scafiolding other than what has been described.

' In laying a wall, the brick-layer starts to lay bricks oh the ground level while he is provide more than two uprights brought up standing on the ground, and the bod-carrier places the bricks and mortar for the first three feet of the wall near the brick-layer. When the wall has been built up to about the three foot level, the brick-layer has the scaffolding and he places it several feet from the wall with the run boards 4 on the side of the scaifold nearest the wall. He then has the bod-carrier place his bricks and mortar on boards such as are indicated at 10. The wall is then laid up to about the six foot level. After the wall has reached this level, the brick-layer pulls out the sliding supports 8 and has boards placed across between the extended supports. He can then continue to have bricks and mortar disposed on the top of the scaffold, and by stooping he can build the wall on up to nine feet or higher.

Thus, with the simple scafiolding which I have planned, a brick-layer may be very materially assisted, and the speed of the work will be found to greatly increase. It will be usual for the run boards to be temporarily disposed on the supports, although they may be permanently fastened thereto.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is v A brick-layers scaffold comprising upright members, with bracing extending between the upright members so as to provide a rigid structure, a pair of'run board supports extending beyond the vertical plane of the upright members substantially at the three foot level, and a pair of slidingly mounted supports at the top ofethe scaffold substantially at the six footlevel which, when extended, will support a temporary run board.
