SPECIFICATION formingpart of Letters Patent No. 671,004, dated April 2, 1901.
Application tiled October 5, 1898. Renewed September 6, 1900. Serial No. 29,197. (No model.)
To all whom. it may concern.-
Be it known that we, WILLIAM PERRY SHAW and SANFORD S. BROWNLEE, citizens of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a new and useful Extension Step-Ladder and Table, of which the following is a specification.
This invention is a household article embodying four combination interchangeable features-namely, a long or extension ladder, a step-ladder, a table or bench, and an ironing table or board.
One object of the invention is to provide a device embodying these features which shall be cheap and simple in construction and easy to manipulate, so that a servant or any one about the house can readily change the de vice from one form to another, as required.
Another object is to provide for strength, rigidity, and a multiplicity of adjustments without making aclumsy or unwieldy structure.
With these objects in View our invention consists in the peculiar construction of the various parts and in certain novelties of combination, all of which will be fully described hereinafter and particularly pointed out in the appended claims.
In the drawings forming part of this speciication, Figure 1 shows the device as yeX- tended and used as a Wall-ladder. Fig. 2 is a view in section, showing the device folded as a step-ladder. Fig. 3 illustrates in section the parts arranged to provide an ironing table or board. Fig. 4 is a section on the line 4. l of Fig. 1. Fig. 5 shows the device arranged as a table. Fig. 6 is a sectional view of said table. Fig. 7 is a sectional view of the table-top, showing the manner of folding the same; and Fig. 8 is a detail view of tlie joint used in the extension-ladder.
In constructing a combination-ladder in accordance with our invention We employ two main side rails or pieces A,which are connected by strips A', and their upper ends are enlarged upon the rear edges, as shown at A2', and in the rear side of said enlargement are produced the curved notches or recesses A3 just below the top step, and the under side of this step is grooved, as shown at A, to form a continuous socket or recess from side to side of the ladder for a purpose hereinafter explained.
The secondary side rails or pieces B are Supporting-le'gs Care 6o nected by means of cross-rods or rounds O2 65 and C3.
By means of a combination-ladder constructed as described we are able to utilize the parts tomake a WalHadder, as shown in Fig. l, or a step-ladder, as shown in Fig. 2. 7o
To make the wall-ladder, the side rails B are turned up and the legs O then folded close, bringing the cross-rod or round O2 into the notches or recesses A3 and groove A4, thereby providing a lock-joint which will stand any usual strain upon the ladder, the strength of the joint depending upon the strength of the cross-rod or round O2, which will be sufficient for all ordinary purposes.
To transfer the device "into a step-ladder, 8o
the side pieces B are folded back and the legs folded against the said side rails Band the cross-rod or round O2 again brought into the recesses A5 and groove A4, thus forming a lock to prevent the front and rear portions spreading.
In Fig. 3 we have shown the device as an ironing-board, the main rails .A being placed flat upon the door, the side rails B turned up,
and the legs O turned to cross the rails B, the 9o cross-rod or round C3 being tted into one of a series of notches A5, produced in the rails A, while the round 'C2 fits into a notch D2 in the end of a cleat D, attached to the bottom of the board E, the bottom round B of the rails B being fitted into one of a series' of notches D', made in the bottom of the cleat, and by adjusting the round to the desired notch the board can be made any height necessary.
j Figs. 5 and G show the table, which is set up by crossing the rails B and legs O, plac- IOO l most convenient.
It Will thus be seen that We provide a com bination ladder, table, and ironing -board which consists of very 'few parts and which can be quickly and easily transformed from one device to another Without the aid of tools.
Having thus fully described our invention, whatwe claim as new, and desire to secure by Letters Patent of the United States, is-
l. ln a device ofi the kind described, the combination With the main rails having the enlarged upper ends, notched upon their under edges, said main rails being also notched near their lower ends, of the supplemental railspivoted at their upper ends to the main rails, below the notches of the enlarged portion, the cross-legs having cross-rods at each end, said cross-legs being pivoted centrally to the supplemental rails, said supplemental rails having rounds, whereby an extensionladder can be provided, one cross-rod of the cross-legs resting in the notches of the enlarged ends of the main rails and providing a lock-joint, substantially as shown and described.
2. In a device of the kindv described, the l combination with the main and supplemental rails and cross-legs, said main rails having enlarged ends notched as described,the crossrods connecting the ends of the cross-legs, and the upper step having a groove in its bottom face,corresponding With the notches, substantially as and for the purpose described.
3. In a device of the kind described, the combination With the main rails notched near the top and also near the bottom, the supplemental rails and crosselegs having the connecting bars or rods, and the ironing-board having a cleat upon the bottom, said cleat having a recess at one end and notchesin the `bottom near the other end, substantially as and for the purpose described.
