REMOVABLE BRACE BAR FOR TYEPEWRITER TABLES.

Application filed January 19, 1918.

To all whom it may concern:

Be it known that 1, Farmers M. MARSH, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented certain new and useful Improvements in Removable Brace Bars for Typewriter Tables; and 1 do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to removable brace bars for typewriter tables of the folding type and is an improvement on my prior Patent, #1206570, issued to me November 28th, 1916 and the primary object of the invention is to simplify and cheapen the cost of manufacture of the article and at the same time render the same stronger and more durable.

"With these and other objects in view the invention consists in the novel construction, arrangement and formation of parts as will be hereinafter more specifically described,

' claimed and illustrated in the accompanying drawing, forming a part thereof, in which Figure 1 is a perspective view of the improved table,

Figure 2 is a vertical longitudinal section through the improved table showing the brace bar in position and one of the legs locked thereto and the opposite leg in its sprung position,

Figure 3 is a detail sectional view illustrating the improved joint between the brace bar and the leg of the table.

Referring to the drawing in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 1 generally indicates the table which includes the top 2, having the longitudinal and transverse cleats 3 and 1 secured to its lower surface. Hingedly secured to the transverse cleats 1 are the right and left hand frames 5 and 6, which carry the supporting legs. The frames are connected to the cleats 4 by means of any preferred type of hinges 7 and these hinges are secured to the inner meeting surfaces of the frames and cleats. The rear supporting legs are designated by the numeral 8 and these legs are provided with sockets 9 in their inner opposed faces. The

Serial No. 212,645.

brace bar is designated by the numeral 10 and extends from one leg to the other and is formed slightly longer than the distance from one leg to the other, the purpose of which will hereinafter more fully appear. The brace bar has formed on its ends the outwardly extending centrally disposed nobs, pins or lugs 11 for engaging the sockets 9. The frames 5 and 6 are so formed that when it is desired to place the brace bar 10 in position, the frames are sprung apart and the lugs 11 are then placed in the recesses 9. Hooks or tie rods 12 are pivot-ally secured at their upper ends as at 13 to the brace bar 10 adjacent each end thereof, and these hooks are adapted to engage headed pins 14: carried by the rear legs 8 of the frames 5 and 6. Owing to the fact that the brace bar 10 is formed slightly longer than the distance between the frames 5 and 6, the frames normally tend to spring away from each other and thus when it is desired to hook the hooks 12 over the pins 1& it is necessary to press on the ends of the legs and force the same inwardly towards each other and thus the hooks hold the legs against outward movement and hold the brace rod 10 in position. The brace rod 10 acts as a fulcrum for the rear legs 8 when the same are being bent inwardly towards each other to allow the hooks to be positioned over the headed pins 14:.

From the foregoing description, it can be seen that an improved brace is provided for typewriter tables which can be readily placed in position by springing the legs of the table away from each other and then held in position by means of the hooks 12.

By this construction a novel arrangement is provided which allows the table to be readily and quickly assembled and presents a rigid structure in which the parts are absolutely prevented from becoming disassembled.

In practice, I have found that the form of my invention, illustrated in the accompanying drawings and referred to in the above description, as the preferred embodiment, is the most eflicient and practical; yet realizing the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required without sacrificing any of the advantages of my invention as set forth.

l/Vhat I claim as new is A typewriter table comprising a rigid top, laterally flexible legs or a; width approximately equal to the width of the top and hinged at their upper inner corners to the underside of the top, said legs being pro vided below their upper ends with sockets opening out through their inner sides, a brace bar reinovably positioned between the legs and provided at its ends with knobs located in the sockets, the brace bar being slightly greater in length than the distance between the hinged upper inner corners of the legs to exert a constant outward pressure upon the upper portions of the legs, and tie rods connected to the bar and to the legs below the bar to exert a constant inward pressure on the lower portions of the legs, said tie rods having detachable connection with the legs to permit the bar to be removed and the legs folded one against the other beneath the top and the outward pressure exerted by the bar upon the upper por-- tions of the legs and the inward pressure exerted by the tie rods upon the lower portions oi the legs holding the upper ends of the legs in full contact with the underside of the table and preventing accidental displacement of the bar and accidental disengagement of the tie rods from the legs and preventing any relative movements between the parts of the table.

In testimony whereof I afiix my signature.

Farmers M. MARSH.
