9 Claims.

Our invention relates to improvements in padding supports which are adapted to be disposed upon the upper ends of coiled springs of seats of cars, chairs, lounges and like articles, or over the front ends of the springs of backs of such articles, to keep the padding of the upholstering from getting between or into said springs.

One of the objects of our invention is the provision of a novel padding support of the nature stated, whichis simple, cheap to make, is strong, durable and not likely to get out of order, which is easily applied in its operative position,and which is eflicient in its operation.

Another object of our invention is the provision of a, novel method of making our improved padding support.

The novel features of our invention are hereinafter fully described and claimed.

In the accompanying drawing, which illustrates our invention,

Fig. 1 is a plan view of one of our improved padding supports.

Fig. 2 is a plan view,,showing our padding support in process of construction, and portions of mechanism, which may be employed in such construction, shown'extended across the longitudinal strands or cord-like members of the support.

Fig. 3 is an enlarged cross section on the line 3-3 of Fig. 2. I

Fig. 4 is an enlarged cross 4-4 of Fig. 2.

Fig. 5 is an enlarged section on the line 5-5 of Fig. 2.

Fig. 6 is an enlarged section on the line 66 section on the line of Fig. 2.

Fig. 7 is a reduced cross section showing one of our padding supports with the eyes of one of the transverse members partly completed.

Fig. 8 is a view similar to Fig. '7, showing the eyes completed.

Similar characters of reference designate similar parts in the difierent views.

Our improved padding support comprises spaced apart pliable or flexible longitudinal parallel members, I, preferably of cord-like form, as cords made of twisted paper, or common cords, at the outer sides of which respectively are anchoring members, 2, preferably comprising cordlike members similar to the members I, spaced from and parallel with the members I.

3 designates transverse members, spaced apart and extended through the intermediate members I, and being, preferably, resilient metal wires which are of less diameter than the members I,

and are hard enough to perforate and be extended through the softer pliable members I.

The transverse members 3 each has holding engagement with the longitudinal outer members 2, effected, preferably, by providing the end portions respectively of the members 3 with eyes 4, as shown, which eyes hold the members 3 from endwise displacement. The eyes 4 may be of a diameter permitting in some cases, where desired, movement lengthwise of the members 2,

but in most cases the eyes 4 are in clamping engagement with the members 2, to prevent endwise movement along the outer members 2.

In the making of the padding supports, they may be made in long lengths, of desired widths, and afterward transversely into lengths suitable Y for the purposes in View.

In'the making of the padding supports, the longitudinal members I and 2 may be drawn from rolls, not shown, and the transverse members 3 successively drawn from a roll, not shown, inserted transversely through andv perforating therewith the intermediate members I, so as to project beyond the outer members 2. The wire constituting the member 3, so withdrawn, is then severed, and the end portions of the severed member formed into the eyes 4 around the outer longitudinal members 2, and, when desired, with the eyes 4 formed to embrace the members 2 in tight non-slip engagement therewith.

A modification in the method of manufacture is shown in Fig. 7, in which the end portions of a transverse member 3 are formed respectivelyin two hooks 5, into which the outer longitudinal members 2 are laterally inserted, after which the hooks 5 are closed into eyes 4, which embrace the members 2, as shown in Fig. 8.

Or the eyes 4 may have the outer cord-like members 2 inserted respectively through the eyes 4, and the eyes then crimped into non-slip engagement with the members 2.

The preferred method, however, .is that described as forming the eyes 4 around the members 2 into tight non-slip engagement with the members ,2, after the transverse members 3 have been extended through the intermediate members I.

In the drawing is shown portions of mechanism adapted to make our improved padding supports.

This mechanism comprises an upper transverse member 6 of metal disposed upon, and parallel therewith, a metal member I.

The adjacent sides of the members G and 7 are members I and 2 and the form transverse holes throughwhich are drawn the intermediate members I.

In operation, the wire is drawn from a reel, not shown, or from a roll of wire, and forced through a longitudinal hole intersecting diametrically the holes formed by the recesses 8 and 9, said longitudinal hole being formed by two registering longitudinal arcuate recesses ID in the adjacent sides of the members 6 and I.

The transverse wire is forced through and perforates the intermediate members I to a stop member H, at the right of the members 6 and I, as viewed in Figs. 3 and 4. The wire is then severed at the proper distance from the adjacent ends of the members 6 and l, by shear blades 12, and I3, Figs. 3 and 4. i

At opposite ends of the members 6 and I are two cam wheels l4 and I5 having respectively two cams l6 and II. The cam wheels l4 and I5 have each a shaft l8 rotatable in asupporting member 19, and each of said wheels has through it an axial hole through which is adapted to freely pass the adjacent longitudinal cord-like member 2, Figs. 5 and 6. The shafts l8 have respectively fastened on them two pinions 20 respectively meshing with two racks 2!, which are simultaneously reciprocated in opposite directions, by any suitable means, not shown.

As shown in Fig. 4., the transverse wire 3 when fed through the longitudinal cord-like members I, as has been described, passes under the cams l6 and I1 and above the longitudinal cord-like members 2. After the wire 3 has been severed by the shear blades l2l3, the racks 2| are moved in opposite directions, thereby through the pinions 2U, rotating the cam wheel l4 coun terclockwise, and the cam wheel clockwise. The cams l6 and 11 then form the projecting end portions of the wire 3 around the longitudinal cord-like members 2, to form eyes 4 at the ends of the wire 3, as shown in Fig. 3. By slightly varying the distance of the cams I6-l'| from the axes of the cam wheels i l-45, the cams l5 and I! may be made to vary the diameters of the eyes 4, so that they will tightly clamp the eyes in non-slip engagement with the longitudinal members 2, or, when desired, embrace them loosely.

After forming the eyes 4 around the members 2, the members 6 and l are moved vertically apart, to free the wire 3, and the longitudinal members I, between them. The longitudinal transverse wires 3 are then advanced to the left, as viewed in Figs. 5 and 6, and in the direction indicated by the arrow in Fig. 2, the proper'distance, after which the members 6 and I are returned to their operative position, shown in Figs. 3 and 4, and the racks 2| are retracted to position the cams I6 and I! in their original upper position, shown in Fig. 4.. This completes a cycle of operations.

The operations, just described, are repeated to form a net work of considerable length, after which it is severed transversely into padding supports of desired lengths. These supports may be disposed and fastened in operative positions, in any desired manner, upon the tops of coil springs of seats, or against the front ends of coiled springs of backs, and the padding of the upholstering applied thereon. The size of mesh of the padding supports so made is made small enough to prevent the padding entering between or into the springs.

If'desired, these padding supports may beused by themselves, or against fabric strips or sheets, such as burlap, or canvas covering the springs.

In the construction, it is preferred to employ cord-like longitudinal members I and 2, made of twisted strips of tough paper, as such members can be readily perforated by the transverse wires 3, and can be tightly gripped by the eyes 4 without damage.
