COMBINED LADDER AND CHAIR.

' Specification of Letters Patent. Patented N 23 1920 Application filed March 9, 1920. Serial 1V0. 364,369.

To all whom 2'25 may concern:

c it known that I, TONY BUH, a cit zen of the United States of America, residing at Reitz, in the county of Somerset and State of Pennsylvania, have invented certain new and useful Improvements in Combined Ladders and Chairs, of which the following is a specification.

This invention relates to a certaln new and useful combined ladder and chair particularly adapted for use in and around dwellings, the device presenting a ladder construction. which may be readily converted from one type adapted to be braced. against a wall to another type wherein the ladder per so is propped without requiring wall support. I v

the principal ob ect oi the invention is to provide a ladder of the above kind which, when tilted in one direction, will be propped for use in open spacewith the steps thereof horizontally disposed, and which when tilted in the opposite direction is adapted to be leaned against a wall or other support and still have its steps horizontally disposed.

\Vith the above general ob ects in view and others that will become apparent as the invention is better understood, the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimech In the drawings wherein like reiterence characters indicate corresponding parts throughout the several views,

Figure l is a side elevational view of a combined ladder and chair constructed in accordance with the present invention, the

same being partly broken away,

Fig. 2 is a front elevational view thereof,

Fig. 3 is a view similar to Fig. 1 with the ladder in oppositely tilted position,

Fig. 4 is an enlarged horizontal sectional taken substantially upon line IV-IV of Fig. 1,

Fig. 5 is an enlarged sectional v ew taken substantially upon line V-V of Fig. 3,

Fig. 6 is an enlarged sectional view taken upon line VI-VI of Fig. 8,

Fig. 7 is an enlarged sectional view taken substantially upon line VII-VII of Fig. 3, and

Fig. 8 is an enlarged fragmentary sectional view taken substantially upon line VIII-VIII of Fig. 1.

Referring more in detail to the several v ews, the present invention embodies a partlal chair construction of common form emeach corner braced and connected by rungs 7.

he seat 5 is provided with longitudinal elongated slots at each side thereof as at 8 ad acent the rear edge of the same, and the lower ends of the side rails 9 of the ladder per so are pivotally mounted in these slots by means of pins 10 or the like which are carried by the seat 5. The ladder is provided with a pair of props 11, each of which are pivotally and slidably attached by means of a pin and slot connection 12 to the upper ends of the side rails 9, the lower ends oi the props 11 being slidably disposed within longitudinal side grooves 13 pins 14 secured therein, and a plate 15 is secured on the upper surface of the seat 5 so as to partially cover the grooves 13 and engage the pins 14 so as to retain the lower ends of the props 11 within the grooves 13. The plates 15 are provided with longitudinal slots 16 of such length as to permitthe lower ends of the props 11 to slide backwardly and forwardly relative to the seat 5, and the side rails 9 are connected to the props 11 by the usual links 1"? adapted to hold the ladder in propped condition in the usual and well known manner. The side rails 9 are preferably rigidly connected by transverse braces 18 or the like which hold said side rails in proper spaced relation.

plurali yof fiat steps 19 are pivoted adjacenttheir 'orward. edges between and to the side rails 9 as at 20, and these steps project rearwardly and are pivotally attached as at 21 to a pair of side strips 22, one strip 22 being and adjacent to each side rail 9, and the strip 22 being substantially of the same length as the side rails 9 as seen in Figs. 1 to inclusive. The plate 15 is provided at its rear end with an upstanding bracket 23 composed of a pair of cars to which the lower ends of the links 24: are pivotally connected by means of pins25, there being a pair of links '24 for each strip 22, and each pair of links'2i being pivotally mounted at the sides of a strip 22 adjacent the lower end of the ladder asat 26. A step 27 is pivotally mounted as at 28 to and between arranged parallel withthe seat 5 is used as step retained in'the grooves 30 and allowed slid- It will thus be ap ing movement therein. parent that the step 27 ay be propped by the bail 29 inan operative horizontal position as seen in Fig. 1 or will be'permitted to swing upwardly to a substantially vertical inoperative position as seen in Fig. 3.

With the parts of the device disposed as shown in Fig. 1, it it is desired to move the various parts so as to provide a wall.

supported ladder, it is merely necessary that the rails 9 be swung rearwardly to the position of Fig. 3, hen this is done upward movement is imparted. to the strips 22 through the links 24: so steps 19 always horizontally disposed or substantially so. It is of course to be understood that the joint between the links 17 is first broken before the rails 9 are pushed rearwardly so that the props 11 can move in the grooves 13 rearwardly, and the props ll can move downwardly with respect to the upper ends of the rails 9 through the provision of the pin and slot connection 12. hen the parts are thus brought to the position of Fig. 3, the ladder may he leaned against a wall and conveniently used, or the ladder may act as a chair back when a chair member. reverse of this operation takes place when 'the parts are shifted forwardly from the position of Fig. 3 to the position of F 1. it will also be obvious that a propped. ladder construction is'provided when the parts are disposed as shown in Fig. 1 so that it is not necessary to lean the ladder against a wall when making use of the same. "When the device is used as a propped ladder, the 27 becomes serviceable in mounting the ladder, while the seat 5 may be employed for this purpose when the device is used in its condition of Fi 3.

From the foregoing description it is believed that theconstruction and operation of the present invention as well as the advantages thereof will be readily understood and appreciated. by those skilled in the art.

Minor changes may be made without departing from the spirit and scope of the inventi on as claimed.

1. In aladder of the class described a support, a pair of upwardly extending side rails rigidly connected in spaced substanas to maintain the tially parallel relation and having their lower ends pivoted on said support, a pair of props slidably connected at their lower ends with the support for limited movement toward and away from the lower ends of: said side rails and pivotally and slidably connected at their upper ends to said side rails, a plurality of flat steps pivotally mounted between said side rails, and means connected to said support and to said steps for operatively maintaining the steps horizontally disposed at all times when the ladderis swung upon the pivots at the lower ends of said side rails.

2. In a ladder of the class described a support, a pair of upwardly extending side rails rigidly connected in spaced substantially parallel relation and having their lower ends pivoted on said support, a pair otprops slidably connected at their lower ends with the support for limited movement toward and away from the lower ends of said side rails and pivotally and slidably connected at their upper ends to said side rails, a plurality of flat steps pivotally mounted between said side rails, means connected to said support and to said steps for operatively maintaining the steps horizontally disposed at all times when the ladder is swung upon the pivots at the lower ends of said side rails, said last named means comprising a pair of strips extending upwardly from the support in spaced substantially parallel relation with the side rails and pivoted to said strips, and links pivotally connected to said support and to the lower ends of said strips.

3. In a device of the class described, a Hat base having longitudinal side grooves, a pair of upwardly extending side rails pivoted at their lower ends adjacent the rear ends of said grooves upon horizontal pivots, a pair of props slidably and pivotally con nected at their upper ends to the upper ends of said side rails, transverse pins carried upon the lower ends of said props withinsaid grooves, slotted cover plates for said grooves engaging said pins for retaining the lower ends of said props in said grooves while permitting movement of the lower ends of said props towardand away from the lower ends ofsaid side rails, steps pivotally mounted between said side rails, and means operatively connecting said steps with said base for maintaining the steps horizontally disposed at all times when the props and side rails are moved relative to the base for converting the device from a wall supported ladder to a propped one.

In. testimony whereof I aflix my signature.

Tour BUH.
