Beit known thatl, Jeun FRANKLIN BROWN, a resident of Knoxville, titate of Pennsylvania, have invented a new and useful lnuirovement in Spring' Bed-Bottoms; and l do hereby declare the following to be a full, clear, and eX- act description thereof.

My invention relates to spri1'1g'-bottomsfor beds, couches, and the like, and more especially to that type having a plurality of helical, conical, or double-conical springs set on end and arranged in rows.

My invention relates especially to a clip for 'fastening' together the end coils of adjacent springs, together with a comiectingrod cooperating therewith.

'lhe object of the invention is to provide connecting means for springs of the character described which are simpleand cheap to make, easily applied, which do not require theknottingl of the springs, which give a perfectly smooth surface to the spring-bottom, thus preventing the catching' and tearing of mattresses, cushions, and clothing, and which are self-adjusting, so as to accommodate themselves to springs slightly out of true or of slightly-different diameters.

lo the accomplishment of the foregoing' objects my invention consists in the construction and arrangement of parts hereinafter described and claimed.

ln the accompanying drawings, Figure .l is a plan view of a portion of a bed-bottom constructed according to my invention. Fig'. 2 is a vertical section on the line 2 2, Fig. 1. Fig. 3 is a similar view on the line 3 8, Fig 1. Fig. 4t is a plan view of the blank :for the clip. Fig'. 5 is a plan view showing a modilication. ldig. 6 is a vertical section taken on the line 13, Fig. 5, and Fig. 7 is a vertical section showing still another modilication.

My invention may be applied to either a single or double faced bed-bottom. Thedrawings show only the upper face of the bed-bottom; but any bed-bottom having' the springs at one or both ends connected in the manner described and claimed comes within the scope of my invention.

My invention is adapted to any form of helical, conical, or double-cone spring's.

the drawings l have illustrated cone-springs l, but this is a matter o l cl ioice. These springs are arranged in rows, as is common, and united by my improved means. The whole is surrounded by a strong' border wire or rod 2.

The special feature of my invention is the clip Il, which is formed from a ilat band of metal, liig. fl, which is bent into the form of an open link, with the ends thereofoverlapped, and embraces the end coils of adjacent springs, as shown in Fig. 2, in which the end coils of the springs are designated by il, the body of the clip by 5, and the overlapped ends by G. lhese clips or links are provided with openings (preferably slots) extemling transversely of said clips, an openingl i' being' formed substantiall y at the middle of the clip and correspending` openings tl and 9 near the ends thereof, the whole being' arranged so that when the clip is bent to link form these several openings will register. These clips are used for uniting the adjacent springs in rows, lbut not for uniting' the springs of different rows, shown in Fig'. 1. rl`he connection of row to row is obtained by my transverse connecting' member 11, which is formed from wire or a small rod and provided at intervals with crimps or loops 12, which project down through the registering openings in the clips and are suitably keyed therein. These connecting' members have their ends secured to the border wire 2, and as theloops or crimps thereon project down through the clips they prevent movement of the rows of springs laterally. rlfhese connecting-rods will be secured to theclips in some suitable manner. lnFig'. 1 l have shown for this purpose key rods or wires 13, which extend at right angles to the connecting' members 11 and are arranged on that face of the clip opposite to that on which said connecting' members l1 lie and are threaded through the projecting ends of the loops or crimps of said connecting' members. At their ends they are connected tothe border wire or rod. The .rods or wires 13 lock or key the connecti iig-wires tothe clips, and the parts are thereby held against disr-nigagement. These key rods or wires 13 are desirable for spring'- bottoms which must be crated for shipment,

IOO

the practice being to crush the bottoms down as fiat as possible. These key-wires extend across the springs at or near the centers thereof and prevent the intermediate coils of the springs from pushing up through the end coils, and thus prevent the several bottoms from becoming locked together in the crate. For bedbottoms, however, which need not be crated for shipment and in which this danger of locking together when severely compressed does not exist these key-wires may be dispensed with and in place thereof the end of the end coil of the spring will be bent at right angles to form a key member 15, as shown in Fig's. 5 and 6, which will project through the loop or crimp of the connecting member 11, thus serving to.

lock the connecting member to the clip.

In all forms of my invention the ends of the coiled springs are not knotteddthat is, the extreme ends are not coiled around the end coil, as is the usual practice. Vith the modification shown in Figs. 5 and 6 the end of the spring is secured in the loop or crimp of the connecting' member, whereas in the form shown in Figs. 1 to 4 the ends of the spring are bent downwardly, as at 16, and project through a hole 17, formed in the clip. This does away with all the labor necessary for knotting the ends of the springs and also dispenses with the roughness caused by such knots.

The connecting-clip shown is very simple and cheap of construction. It can be made from ordinary sheet or band metal under a press which will cut it out to shape and simultaneously punch therein the slots 7, 8, and 9, as well as the hole 17. This operation may also partially bend the clip to link shape. These clips are made of suiiciently soft metal so that they can be bent to link shape around the end coils of adjacent springs by hand, so as to bring' the several slots thereof into alinement. The connecting' and key rods can be readily assembled therewith. The resultant structure is one having' a smooth outer surface, there being no knots on the springs and no inequalities worth mentioning in either the springs, clips, or connecting-rods. As a consequence there is no danger of the bcdclothing, mattresses, or cushions becoming cut or torn. These link-shaped clips are practically open from their ends to the middle, so that the springs can adjust themselves in case they should be slig'htly over or under siZe or not true circles. Tn practice the clips will preferably be pinched together, as shown at 18,

so as to embrace the end coils of the spring's,

and in case of an oversize spring the end of the clip will be squeezed together, thus holding the spring in place.

It will be observed that the clips described are used merely for uniting the springs in rows, but are not used for uniting the springs of adjacent rows. This transverse connection is gotten entirely by the connecting members 11,

vessie whose loops engage the clips in such a manner as to prevent movement of the rows of springs laterally. By this construction only about half as many clips are needed as with the clips ordinarily used for connecting' similar bedsprings. The connecting-rods 11, furthermore, extend transversely of the clips and lie in the space between adjacent springs, thus filling up that space and preventing the sagging down of the mattresses or cushions in the opening's between each group of four of the springs. By reason of this connecting-rod extending across said space and bridging the same it is possible to place the springs farther apart than would otherwise be the case. The clips can be made of any length, so as to allow for this.

Various modifications may be made in my invention without departing from the spirit thereof. For instance, the slots 7, 8, and 9 instead of extending transversely of the clips may extend longitudinally thereof, and in that case the connecting-rods 11 would lie parallel with the clips, while the key-rods 18 would extend transversely thereof. Furthermore, the central opening' 7 may be entirely dispensed with, if desired, the clip being provided only with the registering openings 8 and 9. This is shown in Fig. 7. ln this modification the loop 12 on the connecting member 11 is comparatively short and the key-rod 13 lies between the body and overlapped end portions of the clip and engages the loops of the connecting member 11 in the manner illustrated.

Various other modifications will suggest themselves to persons skilled in the art.
