Application filed March 3, 1897. Serial No. 625,863. (No model.)

To all whom it may concern: tive view of one end of the latch and stop,

Be-it known that I, SOLOMON W. STERN, a and Fig. 6 a like view of one end of the stop. citizen of the United States, residing at the Similar numerals of reference indicate corcity, county, and State of New York, have inresponding parts throughout the several vented a certain new and useful Combination views. 1 5 5 Table and Step-Ladder, of which the follow- In the drawings, 1 indicates the top, of any ing is a specification. desired shape, shown as rectangular and hav- My invention relates to household furniing depending sides 2, to which are pivoted, ture; and it consists in the combin-ation,with by pins 3, the legs 4, preferably curved, as [o a table or top, of interfulcrumed legs pivoted shown, the upper portions 5 being curved at their tops at diagonally opposite points, reversely to the lower portions 6, each pair of one or both of the legs being provided with legs crossing each other at 7, which point is steps and crossing each other adjacent or near closely adj acent the top 1. their upper ends, at which points they are At the points of crossing the legs are pro- I 5 fulcrumed together, the legs when at their vided with transversely-extending slots 8, inward or closed limit projecting but slightly through which extends a pin 9, provided with beyond the plane of the table or top and when enlarged heads or nuts 10, the pins uniting extended to their full limit presenting their the legs, allowing them to swing on their pivsteps beyond the plane of the table or top, alots 3.

Fig. 5 is an enlarged perspecgether, securely lock them in their closed poroo sition, and limit their extension, I have provided the following cheap and efficient device:

At 12 13 are two flat bars secured at their outer ends 14 15 to the under side of the lower steps 11, their inner ends having squared sleeves 1G 17, each being formed of side pieces 18 and top cars 19, forming a rectangular socket to receive the bars 12 13 and allow them to telescope on each other, and coming together, as in Fig. 2, arresting the extension of the legs.

At 20 are spacing-blocks inserted between the steps 11 and the bars 12 13 to form a space between the steps and bars to allow of the sockets passing below the former.

One of the steps 11 is provided with a springplate 21, having at one end an enlargement 22, formed either by bending the metal of the plate over on itself, as shown, or otherwise, in which are formed holes 23 for the passage of screws 2 to affix the end of the plate to the under side of the step 11 and in line with the plane of movement of the sleeve '16, the front or free end of the plate being bent down to form a tongue 24, in the end of which is formed an opening 25 large enough to allow of the sleeve 16 to pass freely through, the arms 26, formed in the tongue by the opening 25, being provided with a cross-bar 27 to tie the arms together and provide a handle for bending the tongue 24. The plate and tongue on the one hand and sleeve 16 on the other form a latch for holding the legs in the closed position.

The plate 21 lies between the step 11 and bar 13, closely adjacent the latter, and when the sleeve 16 is moved toward said plate in bringing the legs to their closed position the sleeve will pass under the plate, lifting it, and 011 passing through the opening 25 in the tongue will spring back and present its edge in line with the cars 19, thereby preventing the sleeve 16 from passing the tongue and holding the legs together in the closed position.

To free the sleeve from the tongue, it is only necessary to spring the latter toward the step, when the opening 25 will be brought in line with the sleeve, allowing the latter to pass through.

13y reference to Fig. 4 it will be seen that the sleeves 16 17 are in line with the spacingblocks 20 when the legs are closed, so that blocks can act as abutments or stops to limit the inward movement of the legs.

Having described my invention, I claim 1. In an article of the class described, the combination with the top piece, of the paired legs pivoted to the top piece on each side at diagonally opposite points, crossing each other above their centers, there being slots formed in the legs at the points of crossing, and pins movable in the slots and connecting the adjacent legs of each pair, substantially as described.

2. In an article of the class described, the combination with the top piece, of the legs paired by intervening and connecting steps and pivoted to the top piece on each side at diagonally opposite points and crossing each other above their centers, and means for limiting the inward and outward movement of the legs with respect to each other, substantially as described.

3. In an article of the class described, the combination with the top piece, of the paired legs, each leg having the reversed- curve portions 5 and 6, the curved portion 5 of each leg being the shortest, each pair of legs crossing the other at the portion 5 and pivoted to the top piece at points diagonally opposite the portions 6, and steps 11 connecting the legs of each pair together, substantially as described.

4. In an article of the class described, the combination of the top 1, with the reversely curved legs, the upper end of each leg being pivoted to the top at a point opposite the lower end and crossing the other at each end of the top above their centers, there being alining slots 8 formed in each pair of legs at the points of crossing, and headed pins 9 passing through each pair of slots and movable therein, substantially as described.

5. The combination with the top 1, of the legs 4 pivoted thereto and provided with steps 11, a plate 21 secured to one of the legs having spring-tongue 24 and an opening 25, the bars 12, 13 secured at their ends to the opposing steps 11 and having sleeves 16, 17 movable thereon, the sleeve 16 being adapted to pass through the opening 25 to engage the tongue 24, substantially as described.

Signed in the city, county, and State of New York this 2d day of March, 1897.

SOLOMON \V. SIERN.
