S. L. ELDER SCAFFOLD 2 Sheets-Sheet 2 Filed April 28, 19 27 INVENTOR Patented May 8,
SHIRLEY L. ELDER, or HUNTINGTON, wnsrvmemm.
SCAFFOLD.
Application filed April 28, 1927. Serial No. 187,305.
This invention relates to scaffolds adapt ed to position a stage or platform against its work to prevent swinging.
An object of the invention comprehends hanging arms for supporting the platform.
Another object of the invention contemplates means for adjusting a platform upon the hanging arms.
A further object consists of a brace n1echanism to assure rigidity of support.
More specifically stated the hanging arms are provided with step members.
With the above and other objects in view, the invention further consists of the following novel features and details of construction to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claim.
In the drawings:
Figure 1 is an elevation of the invention while in use.
Figure 2 is afront elevation thereof.
Figure 3 is a transverse sectional view taken on line 33 of Figure 2.
Figure 4 is a vertical sectional view taken on line 4.% of Figure 2.
Figure 5 is a horizontal section taken on line 55 of Figure 1.
Referring to the drawings in detail, wherein like characters of reference denote corresponding parts, the reference characters 10 indicate hanging or supporting arms provided with curved ends'll adapted to be extended over the cornice, ledges, sills and other portions of a building structure suitably anchoring said arms.
Step or tread members 12 are carried at spaced intervals along the lengths of the arms and disposed in staggeredrelation to accommodate the feet of an operator when ascending or descending upon the arms. A platform or stage such as indicated at 13 is provided with pivoted links 14: upon the opposed sides thereof and upon the bolsters therefor. Clamping sleeves 15 slidably mounted in superimposed relation upon the arms 10 have pivotally mounted between ears carried thereby the adjacent ends of the links 14. Sleeve members 16 slidably mounted upon the arms 10 are held at deadapted to anchor the sired heights thereon by fastening elements passed through opei'iings arranged at spaced intervals in the lengths of the arms. Clamping sleeves, 17 are carried by the sleeves 16.
Pivoted links 18 intersecting and pivotally connected at intermediate points in their lengths have the outer-most ends thereof pivotally connected wvitli the clamping sleeves 17. bolsters of the platform or stage 13 are adapted to receive appropriate portions of the upper extremities of the links 18 to space the arms 10 in parallelism with the side of a building to repose the adjacent end of the stage or platform thereagainstto overcome swinging. I
hen the stage or platform 13 is shifted for an appreciable distance it is to be noted that the normal arrangement of the links 14 and sleeves 15 would tilt the same and to overcome this diiiiculty the sleeves 15 are reversed from the normal positions.
It is to be noted that the platform and brace mechanism may be raised to a desired height and locked in such position by the aforementioned fastening elements passed through the arms.
The invention is susceptible of various changes in its form, proportions and minor details of construction, and the right is herein reserved to make such changes as properly fall within the scope of the appended claim.
Having described the invention, what is claimed is:
A sc liold etmiprising vertical arm members provided with curved upper ends same upon its work, a platform, sleeve'n'iembers slidably mounted upon the arms immediately beneath the platform,.a pair of vertically spaced clamping sleeves carried by each of the sleeve members, crossed links pivoted together intermediate their ends and having their ends pivoted to the clamping sleeves, and tooth bars depending from the platform and being adapted for engagement with the pivoted links to regulate the platform horizontally of the arms.
In testimony whereof I afiix my signature.
