COMBINED LADDER-HOLDER AND SCAFFOLD-BRACKET.

SPECIFICATION forming part of Letters Patent No. 356,457, dated January 25, 1`887.

Application led May 20, 1886. Serial No. 202,777. (No model.)

To all whom it may concern:

Be it known that I, JAMES A. DUDLEY, a citizen of the United States, residing at Delavan, in the county of lValworth and State of Wisconsin, have invented a new and useful Improvementin Combined Ladder-Holder and scaffold-Bracket, of which the following is a specification, reference being had to the accom panying drawings. y

My invention relates to improvements in a combined ladder-holder and scaii'old-bracket, and has for its object the provision of means which will immovably retain' and hold a ladder in vertical position against a building and also support a staging or platform in an elevated position, whereon painters, carpenters, Src., may stand when at work upon buildings and at a distance from the ground.

With these ends in View the invention consists in the peculiar construction and combination of parts, substantially as hereinafter fully described, and specifically pointed out in the claims.

In the drawings, Figure l is a perspective view of my invention applied to a ladder. Fig. 2 is a detail View showing the upper end of a ladder bearing against a building and the means for holding it immovable in position. Fig. 3 is a detail view ofthe scaffold-bracket, showing its adaptation to the rung of a ladder for supporting astage-plank, shown in dotted lines. Fig. 4 is a side elevation of a building, showing my invention in position for use.

Figs. 5 and 6 are detached detail views of parts of my invention. Fig. 7 is a longitudinal sectional view through the tubular support B and the metallic bar C, and showing the grooves e in the latter.

gitudinal slot, c, for a purpose presently de-` scribed.

C designates a vertically-disposed metallic bar, which extends through and is inclosed by the tubular support B, and is provided with longitudinal grooves c.

A sliding sleeve, D, is fitted on the upper end of the tube B, on which it is capable of vertical adjustment. This adjustable sleeve has a binding-screw, d, which works in a suitable threaded opening therein and projects into and through the longitudinal slot e ofthe tube B, to bear against the bar C and retain the sleeve at any desired vertical adjustment, and thus accommodate the device to different sizes of ladder. The adjustable sleeve is further provided with a right-angled sleeve, d', that is cast integral therewith and carried by the said adj ustablesleeve in its movement, and through the rigid sleeve passes a rod, G', which is arranged at right angles to the vertical bar, and is clamped rigidly in the rigid sleeve by a binding-screw, E', that works in a suitable threaded openingand bears on the rod C. The outer ends of the rod C are bent upwardly or at right angles, as at c, and formed into hooks c, which are adapted to take over one of the rungs of the ladder A and support the tube B and the bar C against vertical movement, as is obvious.

F designates another sleeve, that is fitted to slide freely and longitudinally on the vertical tube B, and this sleeve F carries a bindingscrew, f2, that works in a threaded opening therein and bears on the tube to prevent horizontal and vertical play of the sleeve F. This sleeveF is also provided with a right-angled Sleeve, f, that is cast integral therewith, and this rigid sleeve f is also provided with a bindingscrew,g, which works in a suitable threaded aperture and binds on a horizontal rod, G, that passes therethrough.

The horizontal bar G is placed and held in the sleevef of the adjustable sleeve F by a thumb-screw, g, that passes through the side ofthe adjustable sleeve,as described. The bar G is provided with a longitudinal groove, g',

to receive'the end of the sorewg, and said baris provided at its outer end with a hollow cross-head, G', that receives one end of a tubular rod, H, through which passes a sliding bar or rod, I, the upper end of which is provided with a screw-threaded pointed end, i,

iroo

which is adapted to be screwed into or enter a prevent the rod and ladder from accidental displacement.

The lower end of the rod I is formed into a handle, fi', so that it can be readily turned to force its threaded pointed end into the building. i designates a collar secured upon the rod I near its lower end to form a bearing, against which a second collar, i, bears or operates, the collar t being loosely mounted on the lower end of said rod. The collar s is provided with an arm, t, that projects therefrom and receives one end of a rope, cord, or other like means,J that passes over a pulley,K,sup ported in straps 'lc upon the bar G. A knot or other like stopis secured or formed in the cord J to prevent the latter from passing over the pulley K when the apparatus is being placed in position.

L designates a coiled spring attached to the lower end of the rope or cord J,wliich connects said rope with a second cord or rope that eX- tends and is secured toa suitable object on the ground. The purpose of the spring L is to Aprevent the withdrawal of the rod I from engagement with a building by accidental displacement of the ladder.

I will now proceed to describe the means for holding the stage-plank in position. j

M designates a metallic bar having its inner end bifurcated, the arms or branches m m of which extend laterally or away from each other, and are provided at their free ends with upwardly-projecting hooks m', which engage with the rungs of the ladder. The opposite end of the bracket-bar M is provided with a downwardly-projecting hook, m2, which rests upon the shoulder of the workman or operator who carries or adjusts the bracket and the plank Nsupported thereby. The outer end of the bracket is further provided with an upwardly-bent arm, m3, the end of which is provided with a hook, mi, to receive one of the links of a chain, 0, which passes to an eye, p,

formed at or near the middle of a rod, P. The

ends of the rod are formedinto hooks p,which engage the rungs of the ladder for the purpose of holding the bracket in position and against displacement.

Q designates a rod that passes over the plank and above the bracket, and the downwardly bent ends of the rod are connected to the bracket at the sides of the plank for the purpose of holding the plank in position.

The operation of my invention will be understood without further description,taken in connection with the drawings. i v

At or near the lower end of the verticallymovable tube B, I provide a sleeve or collar, R, that is held onthe said rod by means of a binding-screw, r, which it carries, and this sleeve or collar is provided with a curved hook, R', that is adapted to engage one of the rungs of the ladder to hold or retain the rod and Atube on the ladder to prevent them from slipping.

Having thus described my invention, I claini- 1.
