Application tiled April 20, 1905. Serial Nu. 256.564.

To rtl/f wiz/0712, it may concern.-

Be it known that I, WILLIAM L. VILLING, a citizen of the United States, residing' at Bellevue, in the county of Huron and State of Ohio, have invented certain new and useful Improvements in Brackets; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in scaold-brackets, the object being to provide an improved bracket of this character which is exceedingly strong and durable and which is adapted when not in use to be compactly folded; and my invention consists in the construction, combination, and arrangement of devices hereinafter described and claimed.

In. the accompanying draWingsFigure 1 is a side elevation of a scaffold-bracket embodying my improvements. Fig. 2 is a top plan view of the same. Fig. 3 is a rear elevation. Fig. 4 is a detail sectional view taken on the plane indicated by the line 4 4 of Fig. 1; and Fig. 5 is an elevation of my improved bracket, showing the same folded. Fig. 6 is a detail perspective View of the strain-bar.

My improved scaEold-bracket comprises a staging-bar 1, a strain-bar Q, and a brace-bar 3. The staging-bar and brace-bar are made of L-shaped angle metal, preferably steel. rIhe side web 4 of the staging-bar is provided near its outer end on its under side with a notch 5, which is inclined as shown. It also has a screw-threaded opening 6 for the reception of a thumb-screw 7. At the inner end of the staging-bar its upper web is bent to form a pivotal opening' 8. The strain-bar 2 is made of sheet or plate metal, preferably steel of suitable thickness, and the same is recessed at its upper and lower ends, as at 9 10, and bent to form openings 11 12. The sides of the strain-bar are notched at points a suitable distance from the lower end thereof to form triangularly-shaped points 13, which are bent rearwardly from the strainbar and are adapted to engage the wall against which the scaffold-bracket is placed to prevent the bracket from slipping sidewise. The openings 10 at the upper end of the strainbar register with the opening 8 at the inner end of the staging-bar, and a hanger 14, which forms a pivot, has its intermediate portion inserted in the said openings, its end portions 15 being bent inwardly and upwardly, as shown. Said hanger serves as a pintle to connect the staging-bar to the upper end of the strain-bar. so that they may be folded together. The brace-bar 3 has its outer web 30 bent at, its lower end to form an opening 16, which is placed between and registers with the openings 12 in the strain-bar, and a pivot pin or bolt 17 is placed in said registering openings, so that the lower end of the bracebar is pivotally connected to the lower end of the strain-bar. The outer web of the bracebar, at the upper end thereof, is provided with a notch 18 to coincide with the notch 5, so that the outer end of the staging-bar may be engaged by the outer upper end of the bracebar to detachably loc k them together. The thumb-screw 7 when the brace and staging bars are thus mutually engaged is inserted in screw-threaded

openings

19 and 6 and serves to lock the said brace and staging bars together, so that they cannot become casually detached. When the said thumb-screw has been removed, the bracket may be folded compactly for storage or transportation, as shown in Fig. 5.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A scafold-bracket comprising a stagingbar, a brace-bar and a strain-bar, said staging and brace bars being formed of angle metal and having their inner ends respectively pivotally connected to the upper and lower ends of the strain-bar, the lower -web of the staging-bar having a notch in its lower side and the outer web of the strain-bar having a notch in its upper end to engage that of the staging-bar to detachably secure the upper end of the brace-bar to the stage-bar near the outer end of the latter, the upper end of the outer end of the brace-bar bearing against the under side of the upper horizontal web of the staging-bar when the staging and brace bars are thus connected together.

2. A scaffold-bracket comprising a strainbar having openings in its upper and lower ends and notches in its upper and lower ends IOO IOS

IIO

between said openings, a staging-bar of -angle rnetal having a vertical and a horizontal web, the latter being' bent at its inner end to lform an opening disposed between the open ings in the upper end of the strain-bar, a

pivot in said openings, pivotally connectingv the staging-bar to the upper end of the strain-bar, a brace-bar of angle-iron having an outer web and a side web, the former being` extended at the inner end of the bracebar and bent to form an opening, said opening being' disposed between the openings in nesses.
