'0 ALL WHOM IT MAYHCONCERN:

Be 'it known that we, B. F. KINGMAnand M; V.'B'. SHPARD, of Chienne, inthe county O,f Gook, in the- State of Illinois, have invented a useful Improvement in Spring-Bed Bottoms and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings,'and to the letters of reference marked thereon, making a part lof this specication, in which- Figure 1 is a perspective representation of our invention.

FigureZ, a part of the spring-attachment, as wheneut from sheet metal preparatory to its'v being formed into a loop.' Y

Figure 3, a perspective representation ofthe socket in which thc' end of theY spring is put.I Figure 4, atransversc section ofthe' slat, and the spring-attachment looped around it. Y This invention relates to an improvement in that class of bed-bottoms which have spring-slats resting on coil springs; and our object is to providea. simple, cheap, and du'rabledevice forfastening the latter to the slats, and one which can be readily adjusted to any part oi' the same, and hold the springs irmlyin ari-upright position, and yet so that they-may be readily removed for repairs, or otherwise, as the case may require.

To enable others skilled in the art tofully comprehend the construction and-operation of ourI invention, we have marked corresponding parts with similar letters, and will now give a detailed description.'

A represents the slat of a bedstead, and B an inverted spiral spring, having the usual form, and its base bearing against said slat, whose centre is set directly over the stem J of the spring, 'which stem' is made to t in a hole bored in the lowerframe of the` bottom, in the `usual manner. rllhis arrangement -thus far has a.

common construction, and therefore we consider itno part of our invention.

The device for fastening 'the spring B- tothe slat consists of a strap of thin sheet metal, C, gsl, 2, and 4, having a slot, H, made through it, near one end, iii-Which is iitted a loop, D, figs. 1, 3, and 4, for holding the end cf the spring B in place; and the strap has also a nib or lug,lE`, cutI from it, and turned up so yas to bear against a shoulder of the spring, and hold its end 'in said loop D.` This loop is also made of sheet metal, 'and with lianges F F at its sides, and extending tc the edgesof the strap C, and projecting beyond one end of thel loop, as seen at G G, far enough to lap under the end, I, of the plate (Lto which they are'attached bysoldcr or otherwise, as'mostgconvenient. The strap can novvbebent toshitv the Ashape of the slat A by means of a form for this purpose, and the loop D put throughtheslat H, and the fastening is ready for' use.

The simplest method of making the device consists in cutting the strap (I the required width, generally an inch, and long enough to reach around the yslat A, and then make' the slot H, and cut a semicircular opening for the ni'o when the latter can be raised vto a vertical position. The notch-between theprojections G G can be cut with a die, and the loop D raised with a stamp.

The fastener can either be passed over the end of the slat ,'or opened and put around it, the latter arrangement being an important one, for, when a slat .is too wide, it need not be cutaway, only at the place `Where the fastener is to be put.

In orde'rto adjust the spring, it should be inclined toward the fastener, soas to permit the shoulder P t0 pass inside of the n'ib E, after which the base oi' the spring can be turned flat on to the slat.

It-will be seen from this description that the fastener can be' adjusted to anypart of the slat without the use of nails or. rivets, and at the same time the spring'can be removed Without disturbing it. I I

Having' thus described our invention, what we claim, and desire to secure by Letters Patent of the United States, isl v A bed-spring fastening, consisting of the metal strap C, and loop D, the former having a nib, E, for holding thc spring in place, and a slot, H, through `which said loop passes, and the latter having-projecting ilanges F G fastened to the end of the strap C, and bearing against thefinside of the same, substantially as and for the purpose herein specified.y i 4 v B. F. KINGMAN, M; V. B. SHEPARD.
