6 Claims.
My invention relates to scalolding, and, more particularly toeJ `portable scaffold. e `I;T'I'hef, invention.hasfor an object to provide a devicenf `the class mentioned, which sof simple and. durable-construction, dependable in use, and
enioient44 in l.,actiovn,` and,V which vcan be manufactured and sold at a reasonable cost.
yAnother-A object of my invention isy the provisiomofa -run board and work .board supporting 10 structure, which is suspended. from a single w cable. l .4
..Aiurther object of the invention is the provision of a,vertical1ydisposed sleeve carried by the-,upper end-of the Vsuspended structure for guiding a .hoisting cable to prevent undue swingingyof,thesuspended `structure due to obtaining an. evenly {distributedweight at the lower end of *u :1. 4,;,7 Y l f -`rAffurther object of` the `invention is the provision of'ila standard yor support, which Ais provided with aexibly resilientmember at its upper ,end adapteduso` be supported betweenthe glittering andvsthe `cornice `cita.,building' with the lower end thereof `resting on .the ground, and also providing the support with an eye from which a single ,cable `is suspended.
n, A further objectlof the invention resides in the proyisionof hoisting means for winding the cable uponv a drumand unwinding it therefromfor raising and.lowering the suspended structure .which supports `the run and workv supporting boards.
-For further comprehension of the invention, and of the ,objects andadvantages thereof, reference willbe had'to the following description and accompanying drawing, .and-to the appended claimsun which themvaricus novel featuresof thewitnventionfare more particularly set forth.
,lrrtheaccompanyng drawing forming a part 4o of` this disclosure-. ,Y me Fig. 1 is a side elevation of a suspended scaffold acter-I designates the roo-f of a building, 2, the I side wallthereof, 3, `the cornice and ll, a gutter secured to and carried by the cornice in the usual 55 manner.
V'Iheinvention comprises a suitable standard or support `5, and a cornice and gutter engaging or supporti may be made of any suitablemate- 15 I rial such as two-by-four or other dimensioned lumber, which is easy to handle and4 transport fromone `place toanother, and it may be formed of aA singlepiecehof material, or of a plurality of pieces suitably joined by loop members II and 20 securingpinsIZ. i. *Thalowerend Vof the cable 9 is adapted to be Wou'dupon as'uitable drum I3 rotatably mount? ed by means ofa; shaft Mbetween the members I5 of a suitable frame like structure designated 25 generally as I 6,. The upper ends of the frame ,f members I5 are suitablysecured to a suitable vertically disposedeleeve I1 whichserves as a` guide for thefcablefQ through which it passes adjacentand abovethe drum I3. 30 They means for rotating `the drum I3 includes 1 a worm gear I8 secured to one end of the shaft lli .and a worm I9 ,which engages the teethoi theworm gear I8. The worm I9 is provided with end trunnions grotatably mounted between the 35 ears 2i of a'suitable bracketv member `22, which, is suitably supported by one of the frame'members I 6. ,Oneof the worm trunnions 20 is provided -with a suitable handle 23 for turning the worm I9 in either direction, for either winding 4,0 the cable upon,` or unwinding the cable from they. drum I 3. A A I Depending from the frame like structure vI6 and in. vertical axial alignment with the sleeve I'I, is a suitable member 24. The member 24 45 projects downwardly a suitable distance from the 1, frame structure it, is bent forwardly at a right angle thereto, as at 25, a suitable distance to provide a support for one end of a plank 26 for workmen to stand and Walk upon while working on the side Wall of the building. u ,A The upper end of the vertically disposed memf ber 274 isY bent at a right .angle thereto to form a support 21 for one end of a plank 28 adapted to serveas Ymeans or a bench to support material to be used by the workmen, and without causing the workmen to bend over or reach down to pick up the material. From the drawing, it will be apparent that the work receiving plank 28 is disposed above the run plank 26 and that the planks are arranged on opposite sides of the suspended cable 9, which supports the scaffold support in suspension in such a manner as to obtain an even distribution of weight, thus avoiding undue swinging movement of the scaffold support while workmen are working on the run board 26.
Projecting upwardly from the forward end of the plank supporting member 25, is an upright member, or post 29, the upper end of which is provided with a suitable socket member 30 to receive and support one end of a suitable guide rail 3l.
The reversed Z-shaped structure including sections 24, 25, 21, and 29 are braced by means of a suitable brace member 32, the rear end of which can be curved, as at 33 to engage the wall of the building for bracing the scaffold when in use and upon which it slides when raising and lowering the scaffold.
It is, of course, understood that in setting up the scaffolding that two standards, or supports 5 are employed and that they are spaced a suitable distance apart adjacent the wall of the building, and that a cable is suspended from each support to hold the plank supporting structure in suspension therefrom so that both ends of the planks will be supported to be raised and lowered by the hoisting mechanism, as desired.
In order to prevent the run planks 26 from shifting longitudinally upon their supporting members 25, I employ a metal member 34, suitably and detachably secured to the plank and having recessed ends to receive the members 24 and 29. This metal member is secured to the plank 26 after the plank has been positioned and it is removed before the plank is removed from the plank supporting structure.
The many advantages of the herein described invention will readily suggest themselves to those 45 skilled in the art to which it appertains.
From the foregoing description, it is evident that a simple device for this purpose has been disclosed, but it is to be understood that I do not desire to restrict, or limit myself to the very 2 50 details of the construction shown and described,
which is merely illustrative, it being obvious that changes, not involving the exercise of invention,
may be made without conflicting or departing from the spirit of the invention within the scope 55 of the appended claims.
