DEVICE FOR MAKING WIRE FABRICS.

Specification of Iletters Patent.

Patented. Oct. 12, 1909.

Application filed April 6, 1908. Serial No. 425,567.

To all whom it may concern:

Be it known that I, FRANK H. HAMBLIN, a citizen of the United States, residing at lVorcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Device for Making Wire Fabrics, of which the following is a specification.

This invention relates to a device for wire working purposes and while capable of general use, it is especially designed for the purpose of making wire bed fabrics and similar structures. Ordinarily, a certain type of wire bed fabrics are made by placing short pieces of wire havingbends in their ends in position with each of said bends extending through one of the four eyes or perforations of the square comiecting pieces with which the fabric is supplied. These bent ends of the wires are then bent over.

The invention also involves means whereby fabrics may be made in which the length of the wire varies both longitudinally and transversely with respect to the fabric and means for bending down a plurality of hookshaped ends of the wire at one operation. It also involves the provision of a series of die-holders each transversely adjustable and adapted to be fixed in adjusted positions and each carrying a series of dies for receiving said wires, said dies being longitudinally adjustable in the die-holders and having spacing blocks between them WlllCl'l are readily removable so that spacing blocks of other lengths may be inserted when the mesh of the fabric is to be varied, these dies also being capable of being secured in adj usted positions.

Further objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawing which shows one form in which the invention may be carried out, and in which,

Figure 1 is a plan thereof. Fig. 2 is an end elevation, and Fig. 3 is a sectionalview of a portion of the device on an enlarged scale.

The device is shown as mounted on'a bed 10 which ordinarily is of considerable extent and is provided with one or more guides or ways '11-, on which fit a plurality of dieholders 12. In the form shown thereare two of these guides, one near each end, each of a T-shape and the die-holders are provided with correspondingly shaped and located grooves at their opposite ends which receive the guidesand along which the die-holders are. adapted to slide transversely. The dieholders are fixed in their adjusted positions in any convenient way, as for example, by

screws or bolts 13 screwed into the base plate from below. Each of the die-holders is also provided with a guide shown in the drawings in the form of a dove-tailed groove 14. This groove in each die-holder receives a plurality of dies 15 which are provided with means for engaging the guide or dove-tailed groove 14 of a shape similar thereto so that the dies may be slid along or adjusted longitudinally in the die-holder. This means is sihown in the form of projections 16 on each By having the dies fitthe guide, it will be seen that if either the edge of the die or the guide overhangs the other, the dies cannot be lifted directly upwardly but can be adjusted along the die-holder so as to place them at any desired distance apart. These dies it will be observed are provided with longitudinal grooves 17 and with transverse grooves 18.

Between the dies are located spacing blocks 19 having longitudinal grooves 20 registering with the grooves 17 and loosely fitting the guides of the die-holders but not provided with projections similar to the projections 16 of the dies. On account of this construction, the spacing blocks may be lifted vertically from the die-holders while the dies are movable longitudinally therein only. This provides a convenient way in which the dies may be adjusted and the spacing blocks removed and replaced by others either longer or shorter in accordance 'with the particular adjustment which it is desired to make.

It will be seen that the bottoms of the grooves 17 18 and 20 are all in the same plane and are located not lower than the tops of the die-holders as indicated. Consequently, the unformed fabric can be placed in position on a device made up of a plurality of die holders each carrying a series of dies, as is clearly indicated in the drawings. Another advantage of the invention when applied to the manufacture of bed fabrics,

is that after the die-holders and dies are i properly adjusted, part of the wires 21 may be placed 1n position and the connecting pieces 22 placed on them in a very simple y the die h ld th Wir sun in proper position for receiving the connecting pieces, After the dies and spacing blocks are prop: erly adjusted, they are secured in adj'usted position preferably by means of a pair of; fastening blocks 23 at each end of each dieholden. These fastening blocks are of a shape similar to that of'the dies but do not project as high and they are provided with fastening screws 24 for holding them in position. Then when all is ready a flat plate 25 is brought down by any desired means on the tops of the hookeshaped bends 26 of the wires 21 which are used to form the fabric. This plate bends the wires down intov the position shown in dotted lines in Fig. 3 and securely locks them to the connecting pieces 22. Preferably this flat plate extends across the whole series of die-holders and covers two of the dies in each die-holder so that in operation the plate or bending device is brought down once to bend the wires held by two series of dies across the device and then the latter is fed forward or the plate is fed in the other direction a certain distance. Then the operation is repeated and the fabric is made in a very short time, as will be clearly understood.

While'I have illustrated and described a preferred ferrn of the invention, I am aware that many modifications may be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims, Therefore, I do not wish to be limited to the particular details and constructions shown, but
