IVIATTRESS-WIRE-BENDING MACHINE.
Specification of Letters Patent.
Patented Jan. 15, 1907.
Application filed March 5, 1906. Serial No. 804,306.
To all whom it may concern:
Be it known that I, FRANK J. CROUCH. a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Mattress -I/Vire-Bending Machines, of which the following is a specification.
My invention relates to an apparatus which is designed for bending wire into forms which are subsequently united in the construction of what are known as wire mattresses for beds, couches, and the like.
It consists in a combination of mechanisms and in details of construction which will be more fully explained by reference to the accompanyin drawings, in which Figure 1 is a side elevation, and Fig. 2 a front View, of that portion of the mechanism by which the first bend is made. Fig. 3 is a view of one of the wires partly bent.
For the purposes of my invention it is necessary to bend wires of a certain length so as to form a centrally-located bight or bend, with the two sides extending slightly divergent from this bend to a point where they are again bent to form loops, and thence extend at approximately right angles from their former direction, and finally have loops or eyes formed at their outer ends. For this purpose the straight wires A are laid horizontally upon supports, with one end in contact with a gage-plate 2, this plate being adjusted upon a support, as at 3, so that equal portions of the wire to be bent will project upon each side of the centrally-located cams 4. These cams are separated a sufficient distance and are mounted upon a shaft, as at 5. The cams project behind the shaft and are there connected by a link or rod 6 with a treadle 7, which is conveniently located to be operated by the foot. The pressure of the foot upon the treadle pulls down the rear ends of the cams and presses the center of the wire across a supporting-bar 8, against which the wire is pressed by the movement of the cams, thus doubling the wire upon itself and forming the bight and the two extended sides. In order to prevent these sides from being pushed back and to carry them up to the proper position to make the first bends in these wires, a curved guide 9 is so located that the ends of the wires are caused to move upwardly while the bending takes place and are thus brought substantially into line with and bearing against stationary pins 10.
11 represents slidable rollers having pins 12 projecting at the inner ends and adapted when the rollers are moved inwardly to overlap the pins 10, thus embracing the upturned ends of the wires between these pins 10 and 12. For the end movement the shafts 11 are slidable and turnable in journalboxes, as at 13, and the endwise movement is effected by cam-grooves 14, formed in the outer ends of the shafts, and arms 15, attached to the boxes and having their ends formed to engage with these grooves.
The shafts 11 have pinions 16 mounted upon them, and these pinions are engaged at the proper time by se mental racks 17. These racks are fulcrumed, as at 18, and connecting-rods 19 have one end attached to pins 20, which are located between the fulcrumpoint and theteeth of the segment. These connecting-rods 19 are slotted at the lower end, as shown at 21, and the slots fit and are slidable upon pivot-pins 22, which pins are movable with the rear end of the cam 4 and through the action of the connecting-rods 6. The first movement of the treadle then serves to depress the rear end of the cam 4 to form the bight in the Wire and to extend the ends of the wire upward by reason of the guides 9 and to place the upwardly-extended ends of the wire against the pins 10. The continued movement of the treadle causes the pin 22 to slide in the slot 21 until it reaches the bottom of the slot. Then the further action pulling upon the-connecting-rod 19 depresses the segmental rack 17 and rotates the pinions 16 and the shafts 11. This causes the cam 14 of each shaft to travel against the arms 15, which extend into the cams, and thus advance the two shafts 11 toward each other until the pins 12 engage the wire upon each side, and the continued rotary movement causes the wire to be bent around to form loops by reason of the pins 12 moving around the pins 10. Thus the first loops are made in the upwardly-bent ends of the wire, and the portion of the wire which extends beyond these loops is bent outwardly at an angle with the two sides formed by the bending of the bight of the wire. These ends do not extend exactly at right angles with the firstnamed portions, and it is now necessary to bend these projecting ends a little more and to form loops at their outer ends.
Having thus described my invention, what I claim, and desire to secure by Letters Pat-- ent, is
1. An apparatus for bending wire, said apparatus comprising a support and gage, means for first bending thewire to form a central bight, and loops intermediate of its ends, said means including a wire-support, an oscillating folding cam-arm, and guides over which the ends of the wires are moved and approached while being folded.
2. An apparatus for bending wire, said apparatus consisting of a support and gage for placing the wire, a plate against which the center of the wire rests, and an oscillating cam engaging the wire upon each side of said plate whereby the ends are first folded up wardly to form a bight, and guides by which the ends of the wire are brought into contact with the loop-former.
3. An apparatus for bending wire, said apparatus consisting of a Wire support and gage, a plate against which the center of the wire contacts, oscillating cams turnable to engage the wire and bend it over the plate to form a bight, and a guide whereby the ends of the wire are directed upward during the bending process, and stationary and revoluble pins by which eyes or loops are subsequently formed.
4. An apparatus for bending wire, said apparatus comprising a support and gage, a
late against which the center of the wire is lield, cams and means for oscillating them in unison so as to bend the wire and form a central bight, guides by which the ends of the Wire are directed during the bending process, and means engaging the wire between the {)ight and the ends and bending it to form 5 In an apparatus for bending wire, a support and gage, cams and means for moving them to engage the wire upon each side of the central support, guides by which the ends of the wire are directed upwardly, projecting pins against which the upwardly-bent por-' tions of the wire contact between the bight and the ends, other pins and means by which they are caused to engage the wire, and by yvhich they are revolved to bend the wire into oops.
6. In an apparatus for bending wires, mechanism for first bending the wires to form a central bight, guides, pins against which the sides of the wires are caused to contact, shafts journaled in line with the said pins and slidable to and from them, said shafts having pins projecting from their ends eccentric to their axes, earns at the outer ends of the shafts, means for rotating the shafts whereby the cams first advance the shafts to engage the wires between themselves and the stationary pins, and subsequently to coil the Wires about said pins. 1
In testimony whereof I have hereunto set my hand in presence of two subscribing wit- IIGSSGS.
