LADDER ATTACHMENT Filed Jan. 15, 1955 2 Sheets-Sheet 1 Inventor July 16, 1935. RJFR'EDRIKSEN 2,008,582

I LADDER ATTACHMENT Filed Jan. 15, 1935 2 SheetsSheet 2 5 4L "7 g/ Q7 Z ,7 M /5 7 zd /d 9 /0, Z Inventor Attorney Patented July 16, 1935 UNITED STATES PATENT OFF-ICE 1 Claim.

The present invention relates to an attachment for a ladder and has for its prime object to provide means tending to prevent the tilting of a ladder laterally along a wall or other surface against which the ladder is leaning.

A further important object of the invention resides in the provision of an attachment of this nature which is simple in its construction, inexpensive to manufacture, thoroughly eflicient and reliable in use, foldable, easy to manipulate and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in view as will appear as the description proceeds, the invention consists in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings:

Figure 1 is an elevation of a ladder showing two of my attachments mounted thereon.

Figure 2 is a fragmentary side elevation of the lower end of the ladder showing one of the attachments. V

Figure 3 is a horizontal section taken substantially on the line 3-3 of Figure 2 looking downwardly.

Figure 4 is a vertical section taken substantially on the line 4-4 of Figure 2.

Figure 5 is a similar section but showing the attachment folded.

Figure 6 is a perspective view of a locking rod.

Referring to the drawings in detail, it will be seen that numerals 5 denote the side rails of an ordinary ladder. There is an attachment on the lower end of each rail. A description of one at--'' tachment will suflice for both. Each attachment includes a block 6 and a block I. These blocks or plates 6 and I are of equal size and are hingedly connected together as at 8 so that the same may be swung to a co-planar position such as shown in Figure 5, or to a superimposed position as shown in Figure 4. The plate or block 6 is adapted to be fixed to the lower portion of a rail 5 by means of a bolt 9 or the like so as to be slightly spaced from the lower extremity thereof. Numeral I0 denotes an elongated plate or block which is hinged as at H to the plate or block I so that one end portion of the plate or block It may be disposed under the lower end of the plate or block 6 and the plate or block I folded down and then an offset rod l0 pivoted as at H on the block l0 may be swung to engage the lower portion of the block 1 thereby holding the block ID securely in a position extending outwardly substantially perpendicularly to the rail 5. By swinging the rod l0 out of the way, the block I may be swung up to the position shown in Figure 5 then the block l0 may be swung up to the folded position shown in Figure 5 and then a hook I 4 swingable on the block 6 may be engaged with a headed pin IS on the block [0 for holding the parts in this folded position.

With the attachment mounted on the ladder as shown to advantage in Figure 1 and with the blocks ID in their outwardly extending position, it will be seen that the ladder cannot be easily tilted laterally along the surface against which it may be leaning.

It is thought that the construction, utility and advantages of this invention will now be quite apparent to those skilled in this invention without a more detailed description thereof.

The present embodiment of the invention has been described in considerable detail merely for the purposes of exemplification since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages. 1

Having thus described the invention, what is claimed as new is:

An attachment of the class described comprising a pair of blocks hingedly connected together and of approximately the same size, a third block relatively longer than the first two mentioned blocks, means hingedly connecting the third block to the second block so that one end thereof may extend under the first block tolimit its swinging movement in one direction and to be disposed substantially perpendicular thereto, and means on the third mentioned block which may be swung into engagement with the second mentioned block when it is swung down in a superimposed relationship to the first mentioned block thereby preventing the swinging of the third mentioned block in the other direction.
