TO ALL WHOM IT MAY CONCERN:

Be it known that I, PLATT C. INGERSOLL, of Greenpoint, in the county of Kings, and State of New York, have invented certain new and useful Improvements in Spring-Bed Slate; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a portion of this specification, in whichl Figure l is a plan view' of a spring-bed slat made according to my invention.

Figure 2 is a side view of the same.

Similar letters of reference indicate corresponding parts in both figures.

This invention may be considered as an improvement' on the bed-Slat patented by PLATT C. INGERsoLL,

October 31, 1865, and its'object is to render the said Slat more yielding and elastic, without in any way impairx ing its strength or durability; and to this end it consists in certain novel combinations of supporting-springs with the sheet-metal and slut-bars, whereby the desired object is perfectly secured.

'.lo enable others'to understand the nature and construction of my invention, I will proceed to describe it with reference to the drawings.

A represents a wooden strip, which constitutes the bottom of the slat, and which may be of any suitable width, and of a length proportioned to that of thc bedstead upon which theslats are to be employed. Situated transversely at one end of the strip, and -projecting upward therefrom, is a block or piece, a, and situated near the opposite side is a low transverse cleat, b. B represents the sheet-metal slat-bars, which may be made of hoop-iron, and of which there are one or more, but preferably two to each strip, A. These Slat-bars, B, are fastened at one end to-fone extremity of the strip A, and, passing over the block ohr piece a, have secured to their under sides, near their opposite ends, a short transverse bar, c, the ends last mentioned being secured in any appropriate manner to the adjacent end of the strip A. A stiff spring,f, is placed between the cleat b and the bar c, and at intervals, underneath the horizontal portions of the Slat-bars, between the same and the strip y A, are spiral or other suitable springs, g, the upper ends of which support cross-bars h, secured to the Slat-bars,

so that the aforesaid springsg serve in a measure to sustain the horizontal portions of the said Slat-bars against the pressure ex-erted by any weight placed thereon.

When the slats are in use, the weight upon the slot-bars, by somewhat depressing the central parts of the horizontal portions thereof, tends to elongate, as it were, the said horizontal portions. The spring f, by yielding slightly, allows of such elongation, without permitting any undue depression of the ends of the Slat-bars adjacent thereto; while the springs g, by sustaining the aforesaid horizontal portions of the Slat-bars, enable themy to support the weight upon them, and at. the same time render the same more elastic, and consequently more comfortable to the person supported-thereby.

What I claim as my invention, and desire to secure by Letters Patent, is

The springs j' and g,'in combination with the sheet-metal Slat-bars B, and arranged in relation to the end and horizontal portions of said Slat-bars, substantially as and for the purposes speciiied.

P. C. INGERSOLL.
