LADDER BRACKE T Filed May 16, 1947 Inventor Fern R. Pennington WWW Patented Nov. 22, 1949 LADDER BRACKET Fern R. Pennington, Paris, 111.

Application May 16, 1947, Serial No. 748,534

3 Claims.

This invention relates to new and useful improvements in ladder brackets and the primary object of the present invention is to provide a scaffold support detachably carried by a ladder.

Another important object of the present invention is to provide a simple attachment for ladders so that the ladder may be used in conjunction with a scaffold or the like.

A further object of the present invention is to provide a device of the character referred to that is quickly and readily applied to or removed from a ladder without in any way interfering with the structural elements of the ladder.

A still further aim of the present invention is to provide a ladder bracket that is simple and practical in construction, strong and reliable in use, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure l is a side elevational view showing the present invention applied to a usual ladder, and supporting a scaffold board with parts of the ladder broken away and shown in section;

Figure 2 is a top plan View of Figure 1;

Figure 3 is a sectional view taken on line 3-3 of Figure 1;

Figure 4 is a perspective view of the anchoring means, the chain receiving sleeve secured thereto; and,

Figure 5 is a top plan view showing the means for attaching the chain to the scaffold support.

Referring now to the drawings in detail, wherein for the purpose of illustration, there is shown a preferred embodiment of the present invention, numeral l6 represents a substantially L-shaped scaffold support preferably T-shaped in cross section, having one end suitably secured to a substantially triangular plate l2, turned outwardly from one end of a U-shaped member M, which is adapted to pivotally and removably engage a selected rung, as for example it, of a conventional ladder designated generally by the numeral l8.

A substantially U-shaped pivotal anchor plate 20 is adapted to engage a selected rung, as for example 22, of the ladder above member M. This plate 20 carries a sleeve 24 having a slot 26, which selectively receives one end of a chain 28. The terminal portion 29 of the sleeve projects outwardly from plate 20 to provide a hand gripping portion for conveniently attaching and detaching the anchor plate 20 relative to a selective rung of a ladder l8.

The other end of chain 28 is provided with a usual self locking link 30, as shown in Figure 5, for detachably connecting the chain to the outer end of the support It).

In use of the device, member [4 engages a selected rung of the ladder and the anchor plate 20 engages an elevated rung of the ladder, as more clearly shown in Figure 1 of the drawings.

The end of the chain extending through sleeve 24 is preferably provided with a ring 34 that prevents the chain from dropping back through the sleeve so that the scaffold support It will remain in a safe position at all times when in use.

The chain 28 is extended through sleeve 24 and a selected link of the chain engages slot 26, for positioning the support Ill in a horizontally disposed position,

The scaffold 32 may be extended between a plurality of said brackets carried by adjacent ladders, whereby the user may conveniently move between the adjacent ladders.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.

Having described my invention, what I claim as new is:

1. An attachment for ladders comprising, a substantially L-shaped scaffold, support, means carried by said support for pivotally and removably connecting said support to a selected rung of a ladder, an anchor plate adapted to pivotally and removably engage a selected run above said support, a sleeve carried by said plate, a slot in said sleeve, and a chain carried by said support adapted for selectively engaging said slot.

2. An attachment for ladders comprising a scafiold support, means carried by one end of said support for pivotally and removably engaging a selected rung of a ladder, an elongated substantially U-shaped anchor plate engaging a rung above said support, a guide sleeve fixed to one leg of said anchor plate, and a link chain carried by the support slidably engaging said guide sleeve, said sleeve having a longitudinal slot for selectively engaging a link of said chain.

3. The combination of claim 2 wherein said sleeve is fixed medially the ends of said anchor '4 plate and is disposed perpendicular to the longitudinal axis of said anchor plate.
