Application .liune 2o, 19%, Serial No. width 26 Claims.-

The main objects of this invention are:

First, to provide an. improved method of and means for assembling spring structures such as cushions consisting of transverse and longitudinal rows of body springs having their end coils suitably conformed to receive transverse and longitudinal helical tie members.

Second, to provide a spring assembling apparatus having means associated therewith for positively and accurately holding the end coils of the body springs in proper position so that in the claims.

the helical tie members can be screwed or threaded into engagement therewith and their crossings interconnected clear of such. end coils.

Third, to provide a spring assembling apparatus of this character which is simple and economical inits parts, and very efficient and efiective'for the purpose intended.

Objects relating to details and economies of my invention will appear from the description to follow. The invention is defined and pointed out Structures which are preferred embodiments of my invention are illustrated in the accompanying drawings, in which:

Fig. 1 is a fragmentary top plan view of a spring assembling'apparatus embodying the features of my invention.

Fig. 4 is a fragmentary view in side elevation of a modification.

Fig. 5 is an enlarged detail section taken on a line corresponding to line 55 of Fig. 4.

The present apparatus is designed by me especially for assembling spring structures of the character disclosed by my copending application, Serial No. 731,419, filed June 20, 1934. In general, such spring structures consist of body springs 1 arranged in longitudinal and transverse rows, the end or terminal coils 2 of the body springs having

straight portions

3 and 4 disposed at right angles to each other with corner offsets 5. The straight portions of the end coils are alined and connected by transverse helical tie members 6 and longitudinal helical tie members 7, the letter being interconnected at their crossing point 8 within the spring structure clear of the end coils of the body springs.

For holding the body springs with their end coils in proper position, I provide a bed 9 which is mounted at one comer 10 for universal adjustment on a stationary support (not shown).

. support (not shown).

of non-circular or square cross section as shown,

(Cl. lied-3) My. bed comprises a head member or bar ll of angle iron and spaced parallel longitudinal supports, members or bars 12 preferably of halfround section, the inner ends of the latter being rigidly secured to one of the flanges of the angle g iron with their fiat faces disposed against the inner side of such flange. The bars 12 are provided with spaced transverse grooves 13 in their flat faces, the grooves being arranged in alined rows forthe passage of the transverse helical tie as members 6.

Adjacent each transverse groove 13 and on the,

bars

12,1 mount three spaced upright -anchoring pins or holders lei, the pins being arranged to form a right triangle, as shown, the sides of the trii5 angles being in longitudinal and transverse alinement at the edges of the bars 12 and transverse grooves 13 respectively. The arrangement in each quadrant of the bed is preferably such that the grooves are between their pins and the end of the 20 bed, and the longitudinal sides of the triangles are adjacent the edge of the longitudinal members nearest the side of the bed.

The spaced pins are arranged and disposed on the longitudinal members to receive between them 25 the corner oifsets 5 in the end coils 2 of the body springs 1 and hold the straight portions 3 and 43 of the end coils in transverse and longitudinal alinement with the straight portions overhanging the transverse grooves and sides of the longitu- 30 dinal and transverse helical tie members may be screwed into engagement therewith from the sides and outer end of the bed bymeans of a spring assembling appliance (not shownl.

The bed is supported for universal adjustment 35 by means of beam 17, channel-like bracket 18, first L-shaped bracket 19, and second L-shaped bracket 20, these parts being pivotally connected by

bolts

21, 22, and 23 arranged at right angles to each other and provided with coiled compres- 40 sion springs 24. acting to establish a certain amount of friction between the parts to hold the bed in adjusted position relative to the stationary The beam 17 is preferably the flanges 25 of the channel being provided with openings 26 fitting the beam. With this universal support, the bed can be universally adjusted as desired, which greatly facilitates the assembling steps. 66

Referring to Figs. 5 and 6, 27 is a longitudinal bar secured at its inner end to the end member 28, the bar having mo ted thereon square posts 29. The posts have room holders or pins 30 at their tops for coaction with the holders 31 of angle section secured to the inner corners of the posts, the holders being adapted to receive between them the corner onsets 5 of the end coils 2 of the body springs l for holding the

straight portions

3 and 4 thereof in alinement for receiving the helical tie members. Otherwise, the apparatus is similar to that described above in connection with Figs. 1 to 4, inclusive.

A spring structure is assembled by means of my apparatus by placing the corner offsets between the uprights 14 as illustrated by Figs. 1 and 2, the uprights acting to hold the end coils with their straight portions in proper position to receive the transverse and longitudinal helical tie members. The latter are screwed into'position from the sides and outer end of the bed, the helicals having a clear passage throughout their travel except where they cross. At their crossing point, the helicals are interconnected clear of the body springs. This results in a superior spring structure, inasmuch as the body springs are free to function independently of each other with the exception of the connection established by the helical ties.

After the spring structure has been assembled in this manner, it is readily lifted from the bed and is ready for use. It is thus seen that my method and apparatus for assembling spring structures is not only simple and economical but produces a superior product.

I have illustrated and described my improvements in embodiments which I have found very practical. I have not attempted to illustrate or describe other embodiments or adaptations as it is believed this disclosure will enable those skilled in the art to embody or adapt my improvements as may be desired.
