SCAFFOLD-BRACKET.

SPECIFICATION forming part of Letters Patent No. 393,560, dated November 27, 1888.

Serial No. 254,165. (No model.)

To all whom. it may concern.-

Be it known that 1, WILLIAM H. HIGGINS, of Forest City, in the county of Susquehanna and State of Pennsylvania, have invented a new and Improved Scaffold Bracket, of which the following is a full, clear, and exact description.

This invention relates to scaffold-brackets, the object of the invention being to improve the construction illustrated, described, and claimed in Patent No. 362,747, granted to me on the th day of May, 1887.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters and figures of reference indicate corresponding parts in all the views.

Figure 1 is a view of the bracket, representi ng it as it appears when adjusted for use in connection. with a single plank, the view being taken from a point beneath the bracket. Fig. 2 is a View of a modified form of bracket adapted for use in connection with a wider scaffold, or when a chimney-scaffold is to be supported. Fig. 3 is a side view of the bracket shown in Fig. 1. Fig. 41- is a perspective view of the brackets shown in Figs. 1 and 2 combined. for use as a support for a wider platform than is shown in Fig. 1.

In the construction shown in Figs. 1 and 3, 10 represents the bracket proper, which consists, essentially, of a flattened forwardly-extending tongue, 11, and an outwardly-extending projection, 12, that is formed with claws 13. Above the flattened projection 11 there are overhanging arms 14, between which arms I pivotally mount an arm, 15, that is formed with a hooked outer end, as shown at 16, and with a bearing-face, 17, just below its pivotal connection with the arms 14.

In applying the bracket above described the tongue 11 is pressed beneath one of the shingles of the roof, and the arm 15 is then turned downward, so that its bearing-face 17 will presshard against the shingle above the tongue 11, in which position the arm is fastened by means of a pin, 2, which is passed through apertures formed in the arms 14 and through the registering aperture of one of a series of apertures that are formed in the web of the arm.

In Figs. 2 and 4 the auxiliary bracket 21 has a forwardly-projecting tongue, 22, to extend under a shingle, and a dowuwardextending claw, like the claw 1.3 of Fig. 1. To the upper forwardly-extending end of'the bracket 21 is hinged or pivoted by its inner forked end an arm, 20, and within this forked end is pivoted the curved arm A. This arm A is toothed at its flattened ends, as shown at b c, to take a firm hold on the shingles,andits upper curved end is also serrated or roughened on its outer face to prevent the plank or platform resting thereon from slipping. To the outer end of arm a connecting-bar, 23, is pivoted.

When it is desired to support a wider platform than can be safely supported by the single bracket shown in Figs. 1 and 3, the connecting-bar 23 is passed into a socket, 24, of the arm 15 of the bracket 10 and supported by its transverse projection plate or collar 23,

which rests on the upper side of the arm 15. The two bracketsthus connected, as shown in Fig. 4, will support a wide platform, as the outer end of the arm 20 will be firmly supported by the connectingarm 23 and the lower bracket.

Having thus fully described my invention, I claim as new and desire to secure by Letters latent 1. The combination, with the bracket 10, having forwardly-projecting tongue 11, and prongs 13 on the lower rear ends of said bracket, ofthe arm 15,pivoted at its inner end to the forwardly-projecting end of the bracket and having a tooth, 17, near its forward end in rear of its pivoted point and projecting approxi mately at right angles to thelength of the arm, a vertical slot in the outer end of said arm, and the pin 2, locking the arm and bracket together, substantially as set forth.

2. Inascaffoldbracket, the auxiliary bracket 21, having a forwardly-projecting tongue, 22, in combination with the arm 20,pivoted to the said bracket 21 and having the curved arm A pivoted to it above or beyond its pivotal point, the ends of the arm A being toothed or serrated, as at b c, and the upper curved end of the arm being serrated or roughened on its upper or outer side, as at a, substantially as set forth.

3. The combination, with the bracket 10,

its tongue 11, and its arm 15, having a slot or extending prongs, an arm pivoted at its inner socket, 24c, beyond its pivotal point, of the end to each bracket, and a connecting-bar bracketZl,havingatongne, 22, and thearn120, hinged to one of said arms and detachably pivoted to said bracket and having the curved connected with the pivoted arm of the other 5 arm A near its inner end and the connectingbracket, substantially as set forth.

bar 23 at its outer end, the lower end of the bar23 being held in the slot or socket 24 of HIGGINS- the arm 15, substantially as set forth. Witnesses: J
