SCYAFFQLD-BRACKET,
SPECIFICATII ION forming part of Letters Patent No. 740,452, dated October 6, 1903.
Application filed June 22. 1903.
To all whom it 11mg concern:
Be it known that 1, WILLIAM MICHAEL, a citizen of theUnited States, residingat Marion, in the county of Grant, State of Indiana, have invented certain new and useful Improvements in Scaffold-Brackets; and I do hereby declare thefollowing 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.
This invention relates to brackets such as are employed upon ladders for supporting scafiolding; and it has for its object to provide a construction which may be easily and quickly attached to and detached from the ladders, which will be cheap and durable,
and which may be adjusted to correspond to different inclinations of a ladder. 1
Other objects and advantages of the invention will be understood from the following description.
In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in both views, Figure 1 is a perspective view showing a bracket attached to a ladder and supporting,- one end of the scafiold-plauln Fig. 2 is a'perspective view of the bracket detached from the ladder. Referring now to the drawings, there is shown a bracket comprising a member 5, which is designed to receive directly a scaffold-plank 6 and which member has at one end a cross-piece 7, having a longitudinal channel 8 in its under face in which is received a rung'9 of a ladder in the use ofthe bracket, the member 5 at such time being disposed in horizontal position, as illustrated in Fig. 1 of the drawings. At the opposite end of the member 5 from the cross-piece 7 is formed alongitndinal slot 10 and resultant spaced members 11 and 12, through which is engaged a transverse pin 13, which is spaced outwardly, from the inner end of the slot to receive behind it the narrowed upper end or tongue 14 ofa brace 15. The formationiof the narrowed tongue results in shoulders 16, upon which the spaced members 11 and 12 Serial No. 162,556. (No model.)
a plate which is pivotally mounted in the longitudinal slot 19 in the lower end 0t the brace, said foot being limited in its pivotal movement by the upper end of the slot in 4 which it is pivoted. The foot projects at 0pposite sides of the brace, and in the under face of its projecting end portions are formed notches 20, and in the arrangement of the brace its lower end is disposed beyond the rung of the ladder, so that said rung is engaged with the notch of the foot at the outer side of the brace. With the pivotal arrangement of the foot and its projection at both sides of the brace the supporting member 5 of the bracket may be arranged to project at either side of the brace, and the foot may be swung into proper position to correctly support the brace and engage the rung.
It will be noted that the spaced members at the end of the supporting member 5 have a plurality of perforations which aline in pairs and which pairs of perforations are designed to interchangeably receive the pin 13, so that the pin, in connection with the base of the slot, will hold the brace andlsupport- 1 transverse pin and the base of the slot and having a longitudinal slot in its opposite end, and a foot pivoted in the longitudinal slot of the brace and projecting with its ends at opposite sides of the latter, said foot having In testimony whereof I affix my signature in presence of two Witnesses.
