MASON' S PLATFORM FOR BUILDINGS.
SPECIFICATION forming part of Letters Patent No. 673,384, dated May 7, 190]. Application filed November 15, 1900. Serial No. 36,558. (No model.)
To all whom, it may concern:
Be it known that LOHARLEs J .OLARK,a cit-izen of the United States, residing in the borough of Manhattan, in the city, county, and State ofNewYork, have invented certain new and useful Improvements in Masons Platforms for Buildings, of which the following is a full and true description,reference being bad to the accompanying drawings, showing a construction embodying my invention.
My invention relates to masons platforms, and has for its object to provide a suspended platform of great strength which may be easily and quickly constructed and adjusted and which has many advantages when compared with the prior forms of platforms.
Prior to myinvention so far as I am aware it has been the usual practice in building masons platforms to build a framework at each floor within the house and to secure to the framework by nails, cleats, or otherwise beams extending outwardly and to place a temporary platform upon the beams outside of the building. In order to allow the masons to continue working up the building, it
was necessary to build a framework at each.
floor and to have beams extend outwardly from each floor, thus requiring the employment of a large quantity of lumber and being very costly. As one result of this system also it was necessary to build the brickwork around the projecting beams, and when the beams had been withdrawn large openings were left in the walls, and to subsequently fill these openings cost considerable time and money. It was also necessary for the masons to build auxiliary platforms resting upon the main platforms, supporting the same upon This resulted in a further cost and delayed the work.
By the employment of my new platform I render the inside supporting-frames unnecessary and use but a single set of outriggingbeams for a plurality of independently-adj ustable platforms, keeping the beams always above the work (there being no openings to be subsequently filled in the walls) and the several platforms or the entire frame being adapted to be quickly raised, lowered, taken apart, or assembled.
Referring to the accompanying drawings, Figure 1 shows several of my platforms secured to a building in course of erection. Fig.2 is asoctional viewof the building, showing the manner of securing a platform in place. Fig. 3 is a top view of parts of the Outriggers, showing manner of securing the depending bars; and Fig. 4 is a top view on line 4 of Fig. l of a put-lock for holding the bars in place and supporting a platform.
The new structure is composed, essentially, of Outriggers A, depending bars B, secured to and spaced apart by the Outriggers, and of put-locks D, bolted to and giving rigidity to the bars B and adapted to support the movable platforms.
The Outriggers may with safety and economy be constructed, as shown, of two beams on a, laid on edge and secured at their inner ends to the buildingsay to the floor-beams Cby means of clamps or yokes X, (see Fig. 2,) and the depending bars B can be secured to the Outriggers by means of bolts or pins 19, passing through openings in the outrigger-s and in the bars.
The bars B (which may be in continuous lengths or bolted together in sections) are provided with openings Y at various points throughout their length, and the putlocks D are secured to the bars by bolts or pins fitted in the openings of the bars underneath the put-locks and by bolts E or other devices at the ends of the put-locks and outside of the bars. By this arrangement the put-locks may be quickly and readily raised without moving the bars, while the outer fastenings E pre vent shifting of the put-locks and impart rigidity to the structure. As shown, the putlocks D are made up of two short beams d and d; but any other form may be used.
The Working platforms maybe made up of loose boards F, resting upon the put-locks, and, as shown in the drawings, two or more platforms may be suspended simultaneously from the Outriggers. Laborers may therefore be engaged in building the upper platform while the masons are at work on the lower or intermediate stage, and each platform maybe shift-ed along its supportingbars independently of another platform, and when work is completed at one platform the platform may be quickly taken apart without disturbing the masons at work above it. The upper platform serves as a protection for the masons below it against falling pieces of iron, tools, or hot rivets when the riggers and framers are at work on the higher-floors. My new construction also permits the workmen to continue during windy and Wet weather. The upper platform will protect the men from rain and snow, and they may be protected from the wind by securing strips of canvas outside of the rods.
The inner ends of the put-locks D rest against the building G and assist in bracing the suspended structure, while any suitable means may be availed of to prevent the structure swinging away from the building. For this purpose, however, I prefer to use one or more inner frames made up of iron bars H and I, the bars Hsupportinginner platforms J, which may be used by masons, lathers, or other workmen. The bars are secured at their upper ends by bolts L to floor-beams, and the rod H is held to the bar I and the inner bar B by belts or pins in substantially the same Way thatthe put-locks are supported by the bars B. The rods H are arranged to project from the building at the places where windows are to be located.
In order to prevent bricks, c. falling from the platforms, the boards M are set on edge against the outer bars B.
As before stated, with the prior forms of platforms it was necessary to build auxiliary platforms upon frames or horses resting on the main platforms. By my construction, however, the masons can raise the platform as desired and without the use of auxiliary frames or horses.
The arrangement and combination of parts described by me and shown in the drawings is preferred by me and has been found highly useful; but other forms and arrangements may be employed without departing from my invention.
What I claim; and desire to secure, is
1. The combination, in a masons platform, of a pair of Outriggers spaced apart and secured at their inner ends to the beams of a building, with bars, outside of the building, suspended from and secured in pairs to each of the Outriggers, each pair of bars being spaced apart by one or more supports fitted thereto by means which permit the supports to be secured at difierent points along the bars, and a platform fitted between the suspended frames'and resting upon the movable supports,substantially as and forthe purpose described.
2. The combination, in a masons platform, of a pair of outri'ggers spaced apart and secured at their inner ends to the beams of a building, with bars, outside of the building, suspended from and secured in pairs to each I of the Outriggers, each pair of bars being spaced apart by suitable means, and a plat form fitted between the suspended frames by means which permit it to be secured to the bars at different points along their heights, substantially as and for the purpose described.
3. The combination, in a masons platform, of a pair of Outriggers spaced apart and secured at their inner ends to the beams of a building, with bars, outside of the building, suspended from and secured in pairs to each of the Outriggers, each pair of bars being spaced apart by suitable means, and a plurality of platforms fitted between the suspended frames by means which permit each platform to be independently secured to the bars at diiferent points along their heights, substantially as and for the purpose described.
4. The combination, in a masons platform, of a pair of outriggers spaced apart and secured at their inner ends to the beams of a building,with a rectangular frame suspended from each of the outriggers, one or more supportsfitted between the bars of each frame by means which permit the supports to be secured at different points along the bars, and a platform fitted between the suspended frames and resting upon the movable supports; substantially as and for the purpose described.
5. The combination, in a masons platform, ofa pair of outrigger-s spaced apart and secured at their inner ends to the beams of a building,with a rectangular frame suspended from each of the Outriggers, and a platform fitted between the suspended frames by means which permit it to be secured to the bars of both frames at different points along their heights, substantially as and for the purpose described.
6. The combination, in a masons platform,
of a pair of Outriggers spaced apart and secured at their inner ends to the beams of a building, with bars, outside of the building, suspended from and secured in pairs to each of the Outriggers, all of said bars being provided with openings at different points along their heights, each pair of bars being spaced apart by put-locks fitting between the opposite bars and having ends which embrace the bars, bolts for securing the put-locks to the bars and passing through openings in said bars, and a platform fitted between the suspended frames and resting upon the put- IIO looks, substantially as and for the purpose described.
In witness whereof I have hereunto signed my name this 8th day of November, 1900.
CHAS. J. CLARK.
