LADDER ATTACHMENT.

Application filed September 24, 1927. Serial No. 221,740.

4 This invention relates to improvements in ladder attachments and more particularly to means for extending either leg of a ladder to permit the same to stand perpendicu larly on uneven or inclined surfaces. A

further object is to provide such an attachment that can be applied to the ladder without alteration of the ladder and that can be readil detached if desired.

A further object is to provide such an attachment that is simple in construction, cheap to manufacture and efficient in operation. With the foregoing and other objects in view the invention consists in the 5 combination and arrangement of parts to be hereinafter fully described, particularly pointed out in the appended claim and illustrated in the accompanyin drawing which forms a part of this appllcation and in whichconnect the legs 2, 3.

Fig. 1 is a front view of a ladder illustrating the application of the invention.

Fig. 2 is a similar view showing a different style or size of ladder.

Fig. 3 is a side view, enlarged, of Fig. 2.

Fig. 4 is a view of the extension leg employed.

Fig. 5 is a view of the locking pin and plate.

Like reference characters denote corresponding parts throughout the several views.

' The reference numeral 1 denotes the rounds of a standard ty e of ladder that en the ladder rests upon an uneven or inclined surface it ordinarily would not stand vertically and in order to remedy this defect and also to have the ladder stand solidly the present attachment is designed.

The attachment comprises an elongated boxing or easing 4 that is open at its lower end and iclosed at its upper end and that at its upper or closed end is secured by; angle bracket 5' 'and bolt 6 to a ladder ,le one casing being. secured to each leg. 1 preferred the angle bracket may be extended downward lengthwise of the front face of the casing or it may terminate where that face meets with the upper end of the casing.

The front face of the casing is formed with an elongated slot 7, as is also the bracket 5 if it extends over this face, and upon each side of said slot with a plurality o horlzontal ribs 8 spaced apart. A leg 9 formed with a plurality of spaced perforations 10 is adapted for removable insertion into said casing through its lower or open end and said perforations 10 will then be in alignment with the slot 7 in the front face of the casing.

An oblong plate 11 is adapted to fit snugly and removably between the said ribs 8 and is formed with a central perforation to receive the latch pin 12 adapted to pass through the said slot 7 and through any one of the perforations 10 in the leg 9 whereby said leg and casing may be locked in adjusted position. The plate 11 will tend to limit play or relative movement between the leg and casing and held to afford a solid footing for the ladder.

What is claimed is In a ladder attachment, a casing adapted to be disposed against one leg of the ladder, an angle bracket for securing the upper end of said casing to said ladder leg, said casing being formed with a longitudinal slot in its front face and with one open end, spaced ribs formed transversely of the slotted face of said casing, a perforated leg adapted for insertion in said casing, the pernature.
