IMPROVEMENT IN BED-BOTTOMS.
Specification forming part of Letters Patent No. 181,723, dated December l2. ldil.
To all whom it may concern:
Be it known that LELIAS P. READ, ofthe city of Chicago, in the county of Cook and State of Illinois, have invent-ed a certain new and lmproved Bed-Bottom, of which the following is a specification My invention has reference to that class of bedbottoms in which spiral springs are employed to support the slats upon which the mattress or bed rests; and consists in an improved method of securing the springs to the aforesaid slats by means of a clamp and bolt, and also in the manner of connecting the slats one to another, all as hereinafter shown.
In the drawing, Figure l is a perspective view of the under side ofthe slat with the spring secured in my improved manner. Fig. 2 is a plan of the under side of the clamp and projection on the lower coil ofthe spring; Fig. 3, a similar view of the clamp and spring, in which a curved projection is shown, Fig. 4, a vertical cross section ofthe clamp, showing the bolt and nut in elevation; Fig. 5, a cross section in plane of line w .10, Fig. 3, showing a modified method of securing the cord; Fig. 6, a bottom plan of the clamp secured to the slat, and showing the mode of connection by a stra-p; Fig. 7, a perspective view of a portion of the strap, and the arm of the clamp with the lug for fastening the strap.
A represents a spiral spring of the form in This spring is attached to the longitudinal slat B by means of a bolt, l), and nut, b', the said bolt passing through the slat and the clamp-piece C. This clamp-piece consists of a cast or stamped piece of metal provided with an angular groove, c, for the reception of a corresponding formation in the lower coil of the spring, and in an arm, c1, projecting outward from the clamp, and furnished with a groove, lug, or slat, as shown, respectively, in figures. The clamp is also supplied with points or pins c2 for the purpose of penetrating into the slat B to prevent the spring A from turning; besides, a hole, c3, is made for the passage of the bolt b, this hole being placed, by preference, centrally in the body of the clamp and within the line of the groove c. The last and largest coil of the conoidal springAis formed with an angular or curved enlargement, c, at the distance of about a quarter of a circle from the end of the wire of which the spring is made. The angle in the wire just described projects outside of the line of the coil immediately above suiiiciently far to admit of placing the bolt I) within the angle c, and still outside and clear of the second coil. The slats B are connected transversely of their length by means of the cord D, which is first placed under the arm c1 and afterward carried around and again passed under it, as shown in Fig. l; or the cord may be secured as shown in Fig. 5, in which case it is directed up through one hole and down through the other, by both which plans the cord is bound securely by screwing down the clamp upon it. If it is preferred to use a strap it is made fast by inserting the downward projection or lug c4, which is at least equal in length to the thickness of the strap, into a corresponding hole in the strap, from which escape is prevented by screwing down the clamp as before, causing said projection to bear upon or enter the slat.
The method of attaching the different parts to gether is as follows: The desired position of the spring on the slat is iirst marked; the spring is then placed as indicated, and the clamp-piece C is tted onto the angular or curved projection c. The bolt b is afterward inserted through a hole previously bored in the slat, and through the hole c3 in the clamp C. The nut b being applied, the clamp-piece is screwed down in close contact with the slat, and the points c2 are at the same time forced into the wood of the slat, thus holding the spring firmly and preventing it from turning in either direction. Should the slats become bent and require to have the sides reversed, or if it should be desired to remove the springs for any other reason, it is easily accomplished by simply unscrewing the nut b and withdrawing the bolt I). The spring may thus be applied with equal facility to the opposite side of the slat. To connect the slats together by means of the cord D a suitable length of cord is taken, and after placing the slats at the proper distance apart the cord is passed beneath the arm c1 upon the clamp C on each of the slats in succession, and afterward each clamp screwed down upon the cord and spring, as before described.
Among the advantages secured by my improved fastenings attention may be called to the great facility with which they can be applied and removed, and their security and durability in use. The angular formation on the lower coil of the spring, which is placed at a distance of at least a qnartvr of a virrlo troin tho ond of thv wit-0 form` ing' said roil, at'thrlls an opportllnit)4 ot' swnring' they spring' to thtslat with thix g'il-atust possaihhl amount ot'tirnnwss hy thi nso ot thel most oonronwnicnt anil oni^ ot thr lightost ot' clamps.
I ani awaru that springs haw lwon attarhcll to slats by lnvans ot' a pit-rv ot' nwtal passotl ovm* sont(l part ot' thel lowvr voil and tai-kul or srrrwml to th(l lslat: also that holts havo horn nsoil passing' through thi slat anil a loop t'ornnwl at thtl vnll g of the springl itsuli'. holding' thtlattir in plaw f by moans ot' a nnt; also that slats hav(l hot-n ronnvrtml tiansrvrsvly hy -ontinnons hanlls 8:0.
