Patented Jan. 9, 1917.
Application filed March 6, 1916. Serial No. 82,287.
To all whom it may concern:
Be it known that we, GEORGE MORE and JOHN Pnrrrsnnw, citizens of the United States, and residents, respectively, of the borough of Queens and the borough of Brooklyn, State of New York, have invented certain new and useful Improvements in Scaffolding, of which the following is a specification.
Thisinvention relates to scaffolding of demountable character, and our improvements are directed to a novel combination of certain components capable of being conveniently assembled, and disassembled, in conjunction with a building under erection, to support the workmen and the building materials and appliances which they employ.
he essential elements employed in our improved scaffolding consist of a number of uprights, suitably spacedapart from each other and from theflbuilding, channel bars extending horizontally from said uprights to the building wall, to support a. flooring, an extension plate, bolted to each channel, and having supporting lodgment within the wall, and means for detachably clamping the channel bars to said uprights; said clamping means also binding in place the lapped ends of skirting boards, which are placed, edgewise, along the front of the flooring.
When the extended, to support an upper tier'of scaffolding, one upright may be placed endwise upon another, v uprights, at opposite sides of the joint, and a strap detachably fitting over said angle plates, and serving to bind them in place.
Other features and advantages of our said invention will hereinafter appear. 7
In the drawing, Figure 1 is a plan view, partly in horizontal section, of our improved scaffolding. v Fig. 2 is a section on the line 2-2 of Fig. 1. Fig. 3 is a section on the line 83 of Fig. 1. Fig. 4 is a horizontal section of the clamping means for the uprights. Fig. 5 is an elevation of Fig.- l.
In the example of our invention illustrated herein, let 1 indicate a wall of a building in course of erection, and 2 an upright, which may be one of a series of uprights disposed a suitable distance from the building, and also suitably spaced apart from each other. A. channel bar 3, may be detachably connected to each of the upheight of the uprights is to be angle plates embracing both rights 2, and extend therefrom, horizontally, to the surface of the building wall, there having an extension, in the form of a plate 3 set edgewise, and secured to said channel 8, as by bolts 4:; said plate finding lodgment in the wall 1 which it penetrates, as between adjacent bricks, or by entering an aperture provided therefor in the material of said Wall. The channels 3 are secured to their respective uprights 2 as bytwo eye-bolts, 5, 6, which lie transversely against opposite sides of the upright, and are connected at their looped ends by a link 7 extending across another side of the upright; said looped ends being here shown as bent inwardly at right angles, to embrace the corners of the up right; the free ends of the eye-bolts penetrating the web of channel 3, and being secured thereto by nuts 7?; whereby the remaining side of the upright, and the channel, are drawn andlbound tightly together. It will be understood that the flange edges of the channel 3 lie against the upright 2, and the security of the union between said channel and upright is effected by the' clamping action of the eye- bolts 5, 6, under the tightening influence of their nuts 7 The scaffolding, as stated, comprises a number of these uprights 2 and channels 3, and, when these are set up, a flooring composed of boards 8 may be laid upon the channels, as is evident. We also provide an improved skirting board, and tie, whereby the double function of preventing material from falling over the edge of the flooring, and of uniting the uprights, is served. This feature of our invention consists in placing boards 9 edgewise along the front of the floor, supported by the channels, said boards being of such length that their ends overlap, where supported, the lapped portions thus occurring alongside the uprights. The skirting boards, thus disposed, are secured to the channel and upright in the following manner: l/Ve provide a clamp 10 consisting of a piece of heavy strap metal, whose central, flat portion lies along the upper flange of channel 3, said strap terminating at its inner end in a rectangular hook 11, which fits over and hugs together the lapped ends of skirting boards 9; and terminating at its other end in an oppositely turned rectangular hook 12, that embraces the free end of channel 3. The clamp 10 is secured to channel 3 by means of a bolt 18, that passes through 7 both flanges of the channel, which flanges are provided with slots 14:, to allow adjust ment of the bolt 13 longitudinally of the channel, before tightening said bolt. The web of channel 8, at its free end, is provided with an open ended slot 15, which receives the eye-bolt 6a screw 16, entered through hook portion 12 of the strap, working in said slot 15, and bearing against a flattened surface 17 on bolt '6, to attain a tensional loc'king relationship between the channel, strap and" upright, and including the skirting boards, priorto tightening up of the bolt 13. Whenthe height of the upright 2 is to be extended, another, similar upright 18 may be placed endwise thereon (see Fig. 5), and a pair of angle plates 19 fitted oppositely.
thereover, as sockets, to embrace the abutting end portions of both said uprights. A pair of angle straps, as 20, may be-secured, as .by riveting, respectively, to said plates 19, said straps having fastening means. As shown, the straps, at adjacent ends, are pro- 'vided with a connecting'li'nk 21, forming a hinge, the strap ends having h a terminal v eye to receive said link, while the opposite,
7 free ends of said straps may be united by a bolt 22.
Variations may be resorted to within the scope and spirit of our said invention, and parts thereof used without others.
Copies -01 this patent ni'a-y be obtained for five cents each, by addressing Vie claim 1. The combination, in demountable scaffolding, of a number of uprights, spaced apart from a building wall, a metal channel extending, edgewise, between each upright and said wall, a detachable clamp uniting each upright and channel, lapped skirting boards supported, edgewise, upon said channels, alongside said uprights, and metal straps having right angularly arranged hooks at their ends, to respectively engage said skirting boards and channels.
2. In combination, a seriesof uprights, a series of horizontally arranged metal channels connecting said upright to a building wall, a series of lapped skirting boards, and a metal strap secured to each channel, one end of said strap being hook shaped to engage said lapped boards, and its other end being hook shaped to engage the free end of said channel, and means for drawing said members tensionally together.
Signed at the borough of Manhattan in the city county and State of New York this 19th day of February A. D. 1916.
