LADDER ATTACHMENT Filed Jan. '7, 1959 INVENTOR A Zfred Mara/12 In; ATTORNEY Patented Oct-3, 1939 UNITED STATES LADDER. ATTACHDIENT Alfred Maran,

Yonkers, N. Y.

Application January 7, 1939, Serial No. 249,700

2 Claims.

This invention relates to new and useful improvements in ladder attachments, and it has for its object to provide a detachable device, which may be readily and easily secured to a ladder to support the weight of a person, whether a workman or a housewife, during the use of said ladder; thus eliminating the necessity of standing on the rung of a ladder, and at the same time giving security and ease to the person, when performing some work from said ladder.

Another object of my invention is to construct the said device so that the latter may be easily adjusted to any height, while the said device, when not in use, may be quickly detached from the ladder and folded into a rather compact form, taking up but little space.

It has been a still further object through the simplicity of construction of the device, to make it possible to manufacture the latter at only an insignificant cost.

With the above and other objects in view, this invention consists of the novel features of construction, combination, and arrangement of parts, hereinafter fully described, claimed and illustrated in the accompanying drawing, forming part of this application, and in which similar characters of reference indicate corresponding parts in all views, and in which:

Figure 1 is a side elevational view of part of a ladder, with my device attached thereto.

Figure 2 is a somewhat perspective elevational view of my device proper.

Figure 3 is an elevational view of part of one of the elongated legs of my device, showing the innersurface of said leg with a slight modifi cation in regard to the latter.

Figure 4 is a side elevational View of the leg shown in Figure 3 with an adjustable attachment secured to the latter; while Figure 5 is a similar view to Figure 4, but showing a still further slight modification of the device.

Referring more particularly to the drawing, l indicates the side bars of a ladder, and II the rungs of the same.

My special device, or attachment, the legs and bars of which are preferably made of iron, is shown separately in Figure 2, and attached to the ladder in Figure 1. Said device comprises the elongated legs l2, which are hingedly connected to upper bars l3, as shown at I8; said upper bars terminate in bends ll adapted to engage an upper rung l I, of the ladder, as shown in Figure 1, and serve simultaneously as support for a board, or platform I, secured thereto by means of screws or bolts l6. Below the bars I! and also secured to the latter bysaid screws 5, other bars I! are arranged. said'latter bars having one end thereof terminatingin'bends ll adapted to cooperate with the bends in en-- gaging a rung of a ladder; a screw-bolt and nut 20 serving further to secure said bends in position upon a rung.

Upon the downwardly extending legs I 2 are 10 secured angularly bent-hook members 2| and 22, each set of which is adapted, according to the adjustment desired; to engage a rung of the ladder, as shown in Figure 1; said hook members are secured to the legs i2 by means of screwbolts 23 inserted through holes 24 in the legs,. there being a number of said holes to permit minutely adjustment of said hook members, as the occasion may require.

In the Figures 3, 4 and 5 are shown a ratchet arrangement for the secure and easy adjustment of the said hook members.

Thus in these views a dented plate 25 is secured upon one side, preferably the inner side of a leg I 2, by means of screws 26, said plate and leg may in the center thereof be provided with a vertical slot 21, permitting the up and down movement therein of a bolt 28, which secures a correspondingly ratchet-formed member 29 to the plate 25 by means of wing nuts 30; said ratchet-formed member terminating in a hook member, as shown at 3!, serving the purpose, as hereinbefore described.

A separate hook member 32 may also be secured to the leg l2 by the ratchet arrangement, as shown in Figure 5.

It must in addition be noted that the bars I! by means of a slot 33 therein, may be so adjusted that the bends IQ of said bars will accommodate any width of rungs.

A cross bar 34 may be riveted to the lower ends of the legs l2, as shown in Figure 2, so as to prevent any swinging of said legs, but, on the contrary, obtain an easy and quick engagement thereof to the rung of a ladder. Said cross bar 34 may also, if desired, be secured to the hook members instead of to the legs.

It is obvious that slight changes may be made in the form, construction and arrangement of the several parts, as shown, within the scope of the appended claims, without departing from the spirit of the invention, and I do not, therefore, wish to limit myself to the exact construction and arrangement shown and described herein.

whatlclaimasnomanddesiretosecure by laitgl'atent of the United States, is:

Llnadeviceoftheclass described,apa1r or iron bars terminating in bent portions adapted first bars, ratchet-plates secured to the inner surface of said legs, the latter and said ratchet plates being formed with vertical slots therein. other ratchet plates adapted for cooperation with said first ratchet plates and terminating in hook 5 portions, whereby to engage the rung of a ladder. and bolts and wing nuts securing said second ratchet plates to the first said ratchet plates.

2. In a device, as claimed in claim 1, and

wherein the downwardly extending legs are con- 10 nected together by means of a cross bar.

ALFRED MARAN.
