LEWIS E. WELLS, OF LITTLE HOCKING, OHIO.

LADDER BUNG AND SOCIUET.

To all whom it may concern:

Be it known that I, LEWIS WELLs, a citizen of United States, residing at Little Hocking, in the county of Washington, State of Ohio, have invented certain new and useful Improvements in Ladder Rungs and Sockets; and I do hereby declare the followmg to be a full, clear, and exact description of the invention, such as will enable others skilledin the art towhich it appertains to make and use the same.

This invention has relation to ladders gen: erally and particularly to the class known in the art as stage ladders.

It is the object of the invention to provide improvements in ladders that will avoid the boring of the side rails and yet enhance the security with which the ends of the rounds or rungs are connected therewith; also, to provide means for keeping the rounds tight in their sockets; also, to provide an im roved construction that will prevent the re. s from spreading; also, to provide improvements that will facilitate the work of re air in case.

- of necessity; and also, to provi e improvements whereby the structure may be made lighter without diminishing its strength.

The nature of the invention is ascertainable from the device portrayed in the anneXed drawings, forming a part of this specification, in view. of which it will first be described in detail with respect to its construction and mode of operation and then be particularly pointed out in the subjoined claims. Of the drawingsFigure 1 is a front elevation of my improved ladder. Fi 2 is a like view of the end of a round secure in a socket connected with the side rail, drawn to an enlarged scale. Fig. 3 is a transverse section through one of the rungs with a part of the side of the ladder in elevation. Fig. 4 is a section on line 44 of Fig. 3. Fig. 5 is a side view of the end of a round. Fig. 6 is a arts of a split socket separated from the rai and round.

Similar numerals of reference designate similar parts or features, as the case may be, wherever they occur.

In the drawings 1 designates the side-rails of a ladder, and 2 the rounds.

Instead of boring the rails and securing the ends of the rounds in said bores, l. form a split socket A formed in two parts 3 and 4,

' each part being provided at its base with right-angular foot-plate 5, perforated for the reception of screw-bolts, 6, whereby the Specification of Letters Patent.

Application filed Harch 25,

Patented June 9, 1908.

1901. serial No. 364,276.'

separate parts may be secured to the inner side of the side rails 1. When the said parts are brought together or nearly together they form a split socket for the reception of the end 7 of a round 2; and in order to effect greater security and stability in the connection ofthe end of the round with the rail, I make the diameter of the socket greater at the point adjacent to the rail than at its inner endgradually tapering the interior from the outer to the inner end,and l shape the end 7 of the round correspondinfly-that is, I taper the end from its extremity inward to an extent corresponding to the depth of the socket, thus forming a shoulder 8 on the round against which the outer ends of the socket portions 9 of the parts 3 and4 may abut. The socketed ortions have perforations formed through t ieir sides for the reception of the shanks of screwrivets'lO that may be tapped into the ends 7 of the rounds.

By the means described it will be seen that the ends of the rounds will be held in the sockets with the utmost security and that weight or stress being brought to bear on the rounds will tend rather to draw the side rails together than to allow them to spread. Should there be a tendency of the parts to become loose byreason of the shrinkage of wood, or from other cause they can readily be tightened by turning up the screw-bolts or rivets. The socket being split in structural character, it can readily be adjusted to varia tions in the sizes of the ends 7, and the parts can be applied and removed with the greatest ease and convenience.

It is proposed to supply the parts 3 and 4, which are identical in form in varying sizes, if need be, ready for application to side rails of varying sizes and strengths. It is also proposed to make and sell the rounds, constructed as described separately from the split sockets, but for use with the same.

W'hat is claimed isl. A socket for securing the ends of a round of a ladder to the side rails comprising two similar parts each forming one-half of a socket of larger diameter interiorly at its outer than at its inner end, gradually tapering from the outer to the inner end, a laterally extended foot plate being formed on the outer end of each-pair of parts, extending in opposite directions and in the same plane and perforations formed through the foot plate and side of the socket part.

#2. A socket for securing the ends of the round of a ladder to the side rails, consisting of a split socket having an interior diameter gradually ta ering from its outer to its inner end, and eac split part being provided with a foot-plate extending in the same plane but in op. osite'directions.

3. n a ladder, the combination of the siderails and rounds, of a socket device -for attaching each end of each round to the side rails, the said rails being imperiorate at the ends of the rounds, the socket de vice comprising two parts, each forming onehalf of the socket, the latter being of larger diameter interiorly at its outer than at its inner end and tapering gradually inward from the outer end, an angular foot-plate being formed on the outer end of each part adapted to it on the inner face of the side rail and perforated to receive a'screw to fasten it to the rail, they end of the round received in the socket being tapered correspondingly to the ta )er of the socket, and the socket being inset in the end to bring its outside surface flush with the outside of the adjacent part of the round.

4. In a ladder,'the combination of the side rails and rounds, of a socket-device for attachiIig each end of each round to the siderails, the said rails being imperforate at the ends of the rounds, the socket device of the round received in the socket being t'apered correspondingly to the taper of the socket, and the socket bein inset in the end to bring its outside surface fiush with'the outside of the adjacent part of the round.

In testimony whereof, I aflix Iny signa ture, in presence of two witnesses.
