Specification of Letters Patent.

Application filed August 2 5, 1906- Serial No. 33.2.035-

Patented'Dec. 25, 1906.

T0 aZZ whom, it may concern:

Be it known that I, HENRY C. CREEDON, a

residing at T0- ledo, in the. county of Lucas and State of Ohio, have invented certain new and useful Improvements in Bedfiqpring Locks, of which I the following is a spec cation.

The present invention relates toimprovements in bed-springs, and more particularly to a novel locking device whereby the various individual spring members within the frame are held in a fixed position with relation to each other and are'prevented from having any lateral displacement.

A further feature of the invention resides in the fact that the various elements constituting the lock cooperate with each other to form a series of braces extending throughout the frame.

The object of the invention is to provide a lock of this nature which is extremely simple and inexpensive'and which can be readily applied without the use of a power stretching-table or other costly apparatus.

For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings, in which- Figure 1 is a top plan View of a portion of a bed-spring constructed in accordance with the invention. Fig. 2 is a sectional view through the same, and Fig. 3 is a perspective view of the lock between the individual springs.

Corresponding and like parts are referred to in the following'description and indicated in all the views of thedrawings by the same reference characters.

The invention is shown as applied to a bedspring, in which the numeral 1 designates the outer frame, and 2 the individual spring members, whichare arranged within the outer frame in a series of parallel rows and which are held relatively in fixed position by means of the locking device. Extending along one side of each of the rows of spring members 2 is a cross wire or strand 3, which is crimped at a point adjacent each of the spring members to form the laterally-extending loops 4, the extremities of which bear against the corresponding spring members 2 in the adjacent row. These loops 4 preferably comprise the two arms 5,. which in the present instance converge, and at their junction with the cross-wire 3. are provided with the offset portions 6 ,which throw the loops. 4 into a plane spaced. fromthe plane of the cross-wires 3. One side of each of the individual spring members 2 is brought into engagement with these offset portions 6 and the spring member thereby effectively held against any latsprings 2 in position and of preventing any longitudinal slipping .of the tie-wires 7. In the exact arrangement of the various parts it will be observed that the loop 4 has its two members converging throughout their length and that said loop by reason of the offset portion 6 lies straight across the upper side of two adjacent spring members. The tiewire 7 as it extends from one spring member to the other passes across one spring member contiguous to and between the offset portion 6 and on the opposite side of the spring member from the loop 4, and thence said tie-wire extends to the next spring member and across the same on the side opposite the loop, and thence is offset vertically in substantial y ogee formation to project upwardly through the small end of the loop and cross the upper side of the loop, being crimped partially around both the spring member and the cross-connecting portion of the loop, which is joined to the two arms 5, as best seen in Fig. 2. By this arrangement not only do the offsets 8 increase the effectiveness of the tiewires 7 as braces for the frame, since a tension member is much stronger, (when braced at a plurality of intermediate points than when simply connected at its extremities,) but at the same time it is believed this arrangement promotes economy in the manufacture of the bed-spring bottoms, because it is much easier to bend a single strand, such as the tie-wires 7 than to bend the two arms 5 at the small end of theloop 4 to secure any crimping and loop effect at this point.

With this constructionit will be apparent that the various spring members 2 within the frame are each engaged upon opposite sides by the offset portion 6 in the cross-wires 3 and the offset portions 8 in the tie-wires 7, respectively, and are thereby effectively held against any swaying movement or lateral displacement.

An important feature in this invention also resides in the fact that any weight brought to bear against the springs simply tends to tighten the lock and hold the spring members more securely against displacement. Owing to the fact that the locking-wires 7 are formed at intervals with the offset portions 8, the same are held against any longitudinal slipping through the cross-wires 3 a and are consequently braced at a series of intermediate points. As a result of this feature a series of brace members are formed which not only reinforce the outer frame 1, but also connect the various parallel rows of spring members 2. The formation of the locking device with the offset portions 8 also has the further advantage of enabling the tie to be applied to the frame without the necessity of employing a power stretching-table or other expensive machinery.

Having thus described the invention, what is claimed as new is In a bed-spring bottom, the combination of a frame, a plurality of spring members in the'frame, cross-wires extend ng across the frame and provided at intermediate points with loops, the arms of which converge throughout their length, said loops being 011'- set from the plane of the cross-wire and extending straight across one side of two adjacent springmembers, and tie-wires extending across the frame at angles to the crosswires, said tie-wires extending across two adjacent spring members upon opposite sides from the sides where the loops are located, said tie-wires being crimped around the spring members at the small end of the loops and extending upwardy through the small end of the loop and thence across and crimped partially around the cross portion connecting the two converging arms of the loop, as and for the purpose set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

HENRY C. CREEDON.
