FOLDING LADDER. 5

Application filed January is; 1925. Serial No. 2,621.

To all whom, it may conccm:

Be it known that l, iVAirsoN TlArLon, J11, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful improvements in Folding Lad dei's; and I do hereby declare the following to beat full, clear, and exact description of the invention, such as will enable others skill .d in the art to which it appertains to make and use the same.

The present invention provides a ladder designed chiefly with tiers of berths whereby to ifacilitate'ingress and egress, said ladder being foldable so as to be out of the way when not required for immediate service.

Other objects and advantages will be ap parent and suggestthemselv es as the nature of the invention is understood.

While the drawings illustrate ail embodiment of the invention it is to be understood that in adapting the same to meet different conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to without departing from the nature of the invention.

Referring to the accompanying drawings forming a part of the specification,

Figure 1 is a front View of a folding lad der embodying the invention,

Figure 2 is a side view of the ladder,

Figure 3 is a sectional view on the line of Figure 1,

Figure 4 is a sectional view on the line 41% of Figure 1 looking to the right as designated by the arrows,

Figure 5 is a front view of the ladder as it appears when folded, one of the side pieces being in section, and

Figure 6 is a detail perspective view of :lragments of the sections of one of the stiles to show the interfitting connection thereof,

and j s Figure 7 is an inverted plan view of the ladder in folded form.

Correspondingand like parts are referred to in the followingfdescription and desig nated in the several views of the drawings byiike reference characters. I

11 116. adememprises similar side pieces, sac. tit the aide ff "iial far for public carriers provided mation and thecorresponding sections being connected by folding rungs. Each of the side piecescon'iprises a top section 1, an interi'nediate section 2 and a bottom section 3, and each of the sections is provided upon the inner side of its upper portion with a recessd to receive a section of a rung when the ladderis folded. Thetop section 1 has its lower portion cut away as indicated at 5 to receive the intermediate section 2, andthe intermediate section its" lower portion cut away as indicated at 6 to 'receive the'bot-- tom section 3; ably connected and are, directed in their movements and retained in place by'tongue and groove joints 7, the arrangement being such as to admit of the several sections C0111 prising a side piece lying in the same plane since tllGSQCtlODS nest or fit one within the other.

The rungs 8 comprise like sections which are hingedlyv connected as indicated at 9 and which are hinged at their ends to the respective sect-ions as'indicated at 10, the respective sections having a rule or butt hinge connection to maintain the rungs in horizontal po-I sition when the ladder is set up for useas ind cated most clearly in Figure 1. A dowel 11 extends across the joint formed between the sections 'of. the respective rungs and serves The several sections are slid to stiffen and brace the joint. Pins 12 pass 7 through openings formed in the respective sections of the side pieces and enter openings formed in the ends of rung sections and operates to hold the parts in operative position and prevent premature collapsing o'fthe ladder. Each of thepins 12 is connected to the respective sections of the side pieces by a flexible connection .13 whereby to preventloss of the pins. Guards 14 are applied to the top and intermediate sections to prevent outward displacement of the sections having slidable connection therewith.

A connector 15 is provided for each of the side pieces and comprises a prong 16 and a clamp 17, the elements of the prong 16 be ing let into openings formed in the top of the section 1, and the clamp 17 engaging a rod 18 or like part provided to form a sup port for the ladder whereby the same be securel held in place to the berth t6 ten dear. entrance and fixit as spending 7 cord 19 or like part associated with the ladder to facilitate the OPt-Bl'iltlfill thereof when raising and lowering the same.

Wi li-at is ClftlD'IGd is:-

Alzultler of the class (lescr-ihecl having stiles, rungs, each rung being in sections hinged together and hinged to the respective stiles, one section of each rung having :1 tenon thereon, the other section of each rung having a mortise adapted to receive the tenon in the operative position of the rung, and pins on the stiles, said stiles and rung sections having recesses adapted to register in the operative position of the rungs, and said pins being insertztlo'le through said openings and into said recesses.

In testimony whereof I affix my signature.
