ALBERT I-I. DANFORTI-I, OF MONSON, MASSACHUSETTS.

STAGING-BRACKET.

SFECIFICATION forming part of Letters Patent No. 600,858, dated March 22, 1898.

Application filed May 20,1897- To all whom it may concern:

Be it known that I, ALBERT H. DANFORTH, a citizen of the United States of America, residing in Monson, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Staging- Brackets, of which the following is a specification, reference being had to the accompanying drawings and letters of reference marked thereon.

My invention relates to folding brackets for the purpose of supporting temporary staging, my object being to provide a bracket of simple construction, light in weight, and inexpensive in manufacture, which may be readily placed in position and removed, and when not in use may be quickly folded so as to occupy but little space, so that the same will be convenient to handle, transport, and store.

In the accompanying drawings, in which like letters of reference indicate like parts, Figure 1 is a perspective view of my improved folding bracket, the same being shown ex tended or in its opened position. Fig. 2 is a perspective view of the same when folded. Fig. 3 is a perspective view of a section of the upper part inverted, showing the attachingrod in position. Fig. 4 is a perspective view of a section of the upper part inverted, showing the recess for the reception of the attaching-rod; and Fig. 5 is a View of a screw-hook adapted to be used when it is not deemed advisable to bore a hole through the studding in the building.

In detail, a indicates the upper bar; I), the folding vertical bars; 6, the plates to which one end of the brace 12 is pivoted; f, a stop mounted in the top bar and against which the brace 19 bears; g, attaching-rod; h, a handnut mounted on the same.

The construction and operation of my device will be readily understood upon reference to the drawings in connection herewith. The top bar a is provided, preferably, with a longitudinal recess or groove in its lower face at one end and provided with one or more transverse openings to receive the upturned end of the attaching-rod g. The attachingrod g is threaded at one end and provided with a suitable hand-n at h, the opposite end of the attaching-rod g being bent upwardly Serial No, 687,323. (No model.)

to enter the opening 2' or '5, the object of the recesses i being to enable me to cause the attaching rod g to project a greater or less distance, as may be desired, from the rear of the bracket, so that the attaching-rod will pass through studding of various thicknesses.

opening through the boarding and studding.

To avoid this,I provide a screw-hook,as shown in Fig. 5, and the same may be screwed into the side Wall of the building, passing through the clapboarding, boarding, and into the studding,and the bracket may be hung there on, the upturned end of the screw-hook entering one of the recesses z. The brace b is pivotally secured to the bar a by a pivot 70, passing through the pieces 6, and these pieces are secured to the bar a by rivets, screws, or bolts, as may be desired. Adjacent to the joint of pivotal connection between the bar a and the brace b I arrange a stop f, the same being preferably mounted in the bar a by cutting a saw-kerf into the lower face of the bar a and inserting therein a metal stop-piece f. The ends of the bar a and brace b, which are located adjacent to the building, are connected by the employment of folding pieces 0 and d, which are preferably attached to the side of the bar and brace, so that when the brace 19 is turned upon its pivot 70 the connectingpieces 0 and 01 will lie against the sides of the bar a and brace b, and the connecting-pivot Z will lie between all, as shown most clearly in Fig. 2. It will be observed that by this construction there is no occasion for providing a means to prevent the connecting-pieces c andd from being turned upon their pivots,

vided and the strain thereon is liable to cause buckling or a turning of the parts upon their pivotal connection is entirely avoided, and no locking mechanism is required to maintain them in an open position.

Having therefore described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combination in a folding bracket of a top bar a, lower brace 19 pivotally secured thereto and vertical connecting-pieces c and d pivotally united and pivotally mounted on the bar a and brace 19 adjacent to their rear ends and means to secure the bracket to a building, substantially as shown.

2. The combination of a horizontally-arranged bar a, a brace 17 arranged at an angle pitching downwardly toward the building and pivotally secured to the bar a, connecting-pieces c pivotally secured to the bar a, at its sides connecting-pieces cZ pivotally secured to the brace b at its sides, the connectingpieces 0 and 01 being pivotally united with each other, substantially as shown.

3. The combination of a horizontal bar a, plates secured thereto, a stop f secured to the bar a, brace 12 pivotally united to the plates 6 and connecting-rods c and cl pivotally united to the bar a and brace Z) and pivotally united sides thereof and projecting below the lower face, connecting-pieces c pivotally connected with the bar a near its rear end, stop f mounted in the bar a, a brace 17 pivotally connected with the plates e and bearing against the bar a and brace or stop f, connecting-pieces d pivotally mounted at the opposite end of the brace b, the pieces 0 and (1 being pivotally connectedwith each other, the bar a being provided with a longitudinal groove and one or more recesses 21 and a supporting-rod having an upturned end to enter the recessest' and having its opposite end arranged to engage the building, substantially as shown. ALBERT H. DANFORTH. Witnesses:
