LADDER-iRON.

SPEGIFIGATZQN forming part of Letters Patent No. 696,848, dated April 1, 1902. Application filed August 8, 1901. Serial No. 70,819- (No model.)

To (0Z6 whom it may concern:

Be it known that 1, CHARLES A. TRUITT, a citizen of the United States, residingat Chincoteague Island, in the coun tyof Accomac and State of Virginia, have invented a new and useful Ladder-Iron, of which the followingis a specification.

My invention relates to improvements in ladder-brackets capable of being attached either to the upper or under side of a pair of ladders when resting against a wall or the frame of a building, &c., in order to furnish a support for a plank or'platform extending horizontally from one ladder to the other for the use of carpenters, painters, or other workmen upon such structure.

The special object of my invention is to provide attaching-hooks for such brackets capable of lateral extension or contraction, thus making such brackets applicable to ladders of any width.

In the accompanying drawings, Figure 1 is a perspective View of my improved bracket applied to the upper side of a ladder. Fig. 2 is a similar view of the bracket applied to the lower side of the ladder. Fig. 3 is a detail plan view of the upper bracket-iron in working position. Fig. l is a similar View of the same part detached and in folded position.

The ladder 1 is provided with the usual rungs 2 2. The platform-support 3 is preferably of wrought metal and of suitable length. It is preferably slotted centrally at 4 and terminated in a vertically-flattened portion 5, having transverse perforations adapted to engage a pin 7, passing through corresponding perforations in a bifurcation 9 on the upper end of the brace 10. The opposite end of the support 3 is provided with extensions or lugs 11 on each side, to which are pivoted, by means of pins or bolts 12, the ends of flattened links 13, which are in turn pivoted at their other ends to the shanks 14 of hooks 15, which are adapted to engage the rungs of the ladder. It will be observed that by rotating the links 13 laterally upon their pivots the hooks 15 may be brought near together, or by rotating them in the opposite direction the links may be located at a considerable distance apart, according to the length of the links, thus adapting this portion of the bracket to engage either wide or narrow ladders. The shanks of the hooks 15 are also provided with transverse perforations adapted to receive a rod or bolt 17, on which are mounted clampingrungs 18, adjust-able at any point on the rod by means of set-screws 19 or otherwise, so that the hooks may be firmly secured in position at any desired distance apart.

\Vhen the bracket is not in use, the links and hooks may be folded back in a very compact manner against the sides of the support, as shown-in Fig. 4.

The lower bracket-iron 20 consists of an arm 21, a cross-head 22, and hooks 23, all of which may be integral or attached to each other in any preferred manner. The arm 21 contains a slot 24, adapted to receive the lower end of the brace 10 and having a transverse perforation to receive a pin 25, by means of which the iron may be connected to the lower end of the brace 10 by passing said pin through the iron and any one of the series of perforations 26 through the lower end of said brace.

The hooks 23 of the lower bracket-iron 20 are doublethat is, each hook has a different form on its opposite sides, making each hook in reality two hooks, one of them having the greater duration and being adapted for use when the bracket is upon the under side of the ladder and the other for use when it is on the upper side of the ladder, the tension being difierent in the two cases, so that hooks of differing form are required. When it is desired to transfer the lower bracket-iron 20 from the upper to the under side of the ladder, the part is removed from the brace 10 and reapplied to the same in reversed position, so as to bring the proper hooks toward the rung.

The adjustable connection between the platform-support 3 and the brace 10 may be made by means of a slotted orbifuroated head or yoke on the upper end of the brace and a flattened bar on the end of the support adapted to enter said yoke, as shown, or the reverse, and the same may be said of the connection between the lower end of the brace and the lower bracket-iron, or other form of adjustable connection between said parts may be adopted, and I do not limit my claims to the precise form of connection shown.

; 2,) a spring 27 may be employed for holding This brace 10 may be, if preferred, made in two sections united by a central splice or otherwise for greater convenience in packing. It is to be understood that in practice a pair of ladders is to be employed; that they are to be placed against the wall or building at about the same degree of inclination, the brackets applied to each of them at the same height, and the plank or platform extended across from one of the supports to the other. WVhether the brackets are applied to the upper or under sides of the ladders will depend upon the exact location and nature of the work.

As shown in the drawings, (see Figs. 1 and the pin 25 in its operative position in engagement with one of the perforations 26 of the brace 10, or any equivalent means may be employed for that purpose.

Having described'my invention, I claim as new and desire to secure by Letters Patent 1. An adjustable ladder-bracket comprising a platform-support provided at one end with a pair of books adapted to engage the rungs of the ladder, said hooks being connected to said support by horizontally-pivoted links, adapting said hooks to be placed at varying distances from each other on the rung, in combination with a diagonally-disposed brace adjustably connected at its upper end with the outer end of said support, and similarly at its lower end with double hooks adapted to engage the ladder-rungs, substantially as set forth.

2. An adjustable ladder-bracket comprising a platform-support provided at one end with a pair of hooks adapted to engage the rungs of the ladder, said hooks being connected to said support by links pivoted to said support and said hooks, a rod or bar extending between said hooks and provided with stops or clamps for holding said hooks at varying distances apart, in combination with a brace adjustably connected at its upper end with the outer end of said support and at its lower end with hooks adapted to engage the ladder-rungs, substantially as set forth.

3. In a ladder-bracket device of the character described, a platform-support consisting of an elongated bar provided at one end with means for adjustably engaging a supportingbrace, and at its opposite end with lateral extensions upon each side, links horizontally pivoted in such extensions, and hooks pivoted in the outer ends of said links, whereby said hooks are made adjustable at varying distances apart, substantially as set forth.

I 4. In a ladder-bracket device, a platformsupport comprising an elongated bar adj ustable at one end to a supporting-brace, and

provided at its opposite end with lateral lugs upon each side, links horizontally pivoted in such lugs, hooks adapted to engage the rungs of the ladder horizontally pivoted in the outer ends of said links, and rods connecting said hooks and provided with spacing clamps whereby said hooks may be adjusted at varying distances apart, substantially as set forth. In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
