SOAFFOLDING SUPPORT.
APPLICATION FILED DEC. e, 1913.
v 1,107,098. Patented Aug. 11, 1914.
FRANK OPELT, or MUSCATINE, IowA.
SCAFFOLDING-SUPPORT.
Specification of Letters Patent.
Application filed December 6, 1913.
Patented Aug. 11, 1914. Serial No. 805,056.
To all whom it may concern:
Be it known that I, FRANK OPELT, a citlzen of the United States, residing at Muscatine, in the county of Muscatine and State of Iowa, have invented certain new and useful Improvements in ScaifoldingSupports, of which the following is a specification.
In building scaffolds of various heights, it is necessary to construct horses on each height. Said horses are unwieldy and cumbersome and difficult to transport from place to place, which frequently results in a waste of material, inasmuch as the lumber from which the horses are constructed is frequently broken in taking the horses apart and damaged to such an extent as to make it practically useless.
The object of my invention is to provide a support for a scaflolding to which uprights of varied lengths may be detachably secured, according to the height desired, and from which the uprights may bereadily detached without injury.
The support may be adjusted to various heights on the timbers, so that one set of timbers may be used for supporting scaffolds at various heights within the length of the timbers.
With these and minor objects in view, my invention consists in the parts and combination of parts as will be hereinafter more fully set forth.
In the drawingFigure 1 is a perspective View of a scaffold embodying my invention; Fig. 2 is an enlarged detail end view of the same with part of the scaffolding omitted; Fig. 3 is an enlarged detail View of the scaffold support.
The reference numeral 1 indicates the vertical timber supports or legs of the horse, 2 the transverse scaffolding support, and 3 the scaffold boards.
The scaffold support embodying my invention consists of two uprights 4 which converge upwardly toward each other.
5 is a transverse support secured between the upper ends of the uprights 4 and depending below said ends. This transverse support may be of any desired size.
6 are collars extending laterally and outwardly from the uprights 4: and of a diameter to be selected according to the size of the legs of the horse to be used. In this connection, I would say that I find that the universal size of timbers sufficient for the average scaffolding used around a building is 2 by l. Each collar 6 is provided with openings in their side walls in which a clamping screw 7 is adapted to project to clamp the legs therein. At the top of each upright f, I locate a clamp screw 8.
9 are lugs projecting outwardly from the uprights at near their lower ends, which, co-acting with the collars and screw clamps, serve to hold the legs of the horse in upright alinement with the uprights I as will be readily understood.
9 are set screws mounted in said lugs.
After having selected the length of timber required for the scaffolding, said timber is passed through the collars 6, and after the support has been adjusted on said timbers to the required height for the scaffolding, the pins 7 are passed through the openings in the collars and through a corresponding opening in the timbers. The lugs 9 receive the legs between them and the set screws are adjusted against the timbers thus keeping the timbers in alinement with the uprights. The timbers are further secured to the support by means of the screw clamps 8. The
supports being thus rigidly secured to the timbers, the transverse scaffolding support 2 is supported in the transverse support 5 to support the scaffolding boards 3.
10 is a brace extending from the lower end of one of the uprights 4 to the lower end of the other upright 4 which serves as a combined tension and compression member for the scaffolding support which prevents the uprights spreading apart or collapsing.
I claim An integral scaffolding support comprising uprights, a combined tension and compression member connecting said uprights at their lower ends and extending therebetween, a substantially U-shaped timber support connecting the upper ends of said uprights and depending therebetween, clamp screws carried by said timber support out Wardly, timber collars extending from said The foregoing specification signed at Musuprights intermediate their ends, clamp catine, Iowa, this 15th day of November, screws carried by said collars, and an out- 1913. wardly extending pair of lugs at the bottom FRANK OPELT. 5 of each upright in alinement with the said In presence of two witnessescollars, and clamp screws carried by said M. F. DUGGAN, pair of lugs, as described. H. M. BARTLETT.
