STRANDING-MKACHINE.

I! C) w m: till, 30

Application filed May 10, lacs. Serial No. 494.98?

To all whom it more; concern: Be it known that I, GEORGE E. Bronnow. a citizen of the United States. residing at lVaterbuI-y, in the county of New Haven and State of Connecticut, have invented certain new and useful improvements in Strundingdl lachines. of" which the followl ing is specification.

This invention relates particularly to l mechanism for assembling wire 'linlzs and perforated plates to form strands] These strands are often connected by cross links to form fabrics such for instance as are made into bed springs. The plates as they come from the ing" machine in which they stampare formed are often somewhatroughand irregular and ditlicult-to teed; Une of my objects is to supplvthese rough plates to the machine and feed theui regularly. I

Another object is to feed the links and I automatically connect them to the plates.

Another objeot is to draw the strand along out of the machine.

To accomplish these 7 7 plates are supplied in a sort of inclined. trough at the b ot ton'l oi which thov are ilattened and from which they are fed interresults the rough mittently to the assembling" position. T he hoolred links are supplied on a guide from which they are fed so as to hook into the rear end of the last plate of the strand ready formed and into the front end of the plate just fed down from the supply trough. The hooks are then partiallv bent over and the strand fed along. At the next operation the hooks are closed down. Means are also provided for holding the plates in their proper positions during the operations.

he accompanying five sheets of drawings illustrate the details of one form of the invention.

Plate sapy Zg The rough plates such as 1 are deposited in any suitable manner in the trougl'i Qwhich is inclined downward at an angle of 4-5" to the horizontal. This trough is open on one side and the edges of the plates are guided by two strips such a s 3. Leading forward from the lower end of trough 2 and downward at an angle of 90 thereto is a chute 4% which leads to the assembling position. This chute 4 is similar ii construction to trough 2.

flats flattenino-l rt the junction of the trough E2 and chute 4 is located a horizontally movable plunger 5 serving as a hammer to strike and flatten each plate as it p a from the trough into the chute. This he mcr normally retracted under the tension of spring 6 and is intermittently actuated between the feeding intervals of the plates. The pivoted lever 7 (see Fig. 3) carries the bolt 8 at the upper end which enplate engaging rgument. owl-l Patented Nov. 1. .2, illllil.

the rear of the hammer 5. This bolt is miljustahle so as to vary the horizontal position of the hammer. The. slide 9 is connected by rod 10 to the crank disk 11 on the main shaft 12 01" the machine so that the slide is reciprocated once in each revolution of the main shift. The block 13 having an inclined cam-lilre surface (shown dotted in Fig. 1) is secured to slide 9 by means of one or more holts or screws such as 14 so that its position may be adjusted longitudinally of the slide. Throughout the greater portion of the stroke of the slide 9, the lower end of lever 7 rests on the long straight portion of block 13 and the hammer is held retracted. Just before the slide reaches its cam. portion of the block 13 presses the 7 outwardly and thus throws the hammer to the right (FigzB) to flatten the plate which is then in position I prefer toprovidean anvil 15 shown dotted in Figs. 1 and opposite the hammer and a bolt or set screw 16 for movin it'to take up wear.

late feeding.A plunger 17 carrying a thin projection or finger 18' slides in line with the chute 4 for intermittently feeding the plates down the chute after they have been flattened by the hammer. A bell-crank lever has one arm 19 connected to the plunger 17 and the other arm 20 depending above slide 9. "The spring 21 normally holds this' :lever and the plunger 17 retracted in the position'shown in Figs. 1, 2, 3 and 5. A pawl 22 is pivoted to arm 20 of the lever and normally pressed by spring 23 against the stop 24 on arm 20. The dog 25 is adjustably seeured to slide 9 by means of one or more set screws on bolts such as 26. and

in a'linement with the pawl 22 Just before the slide 9 reaches the'left hand end of its stroke (Figs. 1 and 2) the dog 25 engages pawl 22, rocks the bell-crank and moves plunger 17 so as to feed one plate down the chute '4. As the length of stroke of the feed plunger 17 is quite short compared to the length of stroke of slide 9 the parts are so proportioned that the pawl 22 is disenaged from the dog before the dog reaches the left hand end of its stroke. WVhen the pawl is disengaged, the spring 21 throws the bell-crank lever and plunger 17 back to the position shown and allows another plate .such asl to slide down the trough 2. On

- the return (right hand) stroke of the dog,

it snapsunder the pawl 22 which yields to permit it. Near the end of the chute 4 is a retarding device consisting of a shoe 27 which is pressed by means of a spring 28 into engagement with the plates as they are fed down the chute. This prevents'the'displacement of the next to the last plate in the. chute and those above it when the bottom plate-is drawn out of its position as hereinafter described. The pressure of the shoe need be only sufficient to'hold the row of plates above in the chute and of course does not add materially to the force necessary to operate the feed plunger 17.

Plate positionin'g.-At the bottom of the feed chute 4 are a pair of pivoted

members

30, 31 which I shall term guards which are pressed by means of springs 32, 33 respecis at the proper distance from the right hand hole of the plate heldby the first pair of guards. (The

pivots

36, 37 of these

guards

34, 35 are horizontally adjustable in slots as shown in Fig. 5 to accommodate different lengths of links.

Link suppZy.-The links such as 40 are formed on suitable wire workin machines into the shapes shown in F ig. 1. the ends being shaped so as to permit of the operations in this assembling machine. An upright member 41 serves to hold a column of a cohsiderable number of these links and is shaped so as to permit the links to slide down readily to the assembling position. v a

Link feeding.--Opposite the lower end of the link guide 41 is located a slide 42 which is moved transversely to the direction of slide-9 by means of a lever 43 which has a roller 44 guided in a groove of cam 45 on, the main shaft 12. This slide-is thus re-j ciprocated once in each rotation ofthe main shaft. The plunger for feeding the links is formed in two parts 46 and .47. The part 47 is clamped to block 47' on the slide 42 by a bolt or set screw 48 so that it may be longitudinally adjusted to accommodate different lengths of links. Both

parts

46 and 47 are transversely adjustable as for in stance by set screws or bolts such as 49 for the purpose of varying the feed of the links. When the slide 42 moves backward, the bottom link on guide 41 drops down in front of the

plunger parts

46, 47. On the return or forward stroke the

parts

46, 47 feed the link forward so that the bent ends pass through the corner holes of the plates held by the guards just described.

Asser/tbZing.Adjac'ent the position of the two sets of uards before referred to and opposite the

feed plungers

46,47 are located two devices 50, 51 which perform the double function of centering and holding the'plates and causing the ends of the-links 'to be bent over and partially closed-as they are fed through the holes in the plates (see Figs. 1, 5 and'8). Fig. 9 shows the right hand device 51. This device has two

fingers

52, 52 for entering'in the upper and lower holes of the plateheld by guards 34,' 35. The flat surface 53 engagesthe face of the plate. The fingers are inserted through the plate until the flat surface 53 engages the faee'of the plate and holds it rigid. A groove 54 hav; ing an inclined surface receives the end of the link'40 as it is fed forward and causes the end to be bent over into the form shown in plan view in Fig. 1. The device 50 is similar to 51 but reversed to accommodate the corresponding end of link 40. Both of these devices are secured to slide 55. This slidehas a roller 56 which fits into a groove.

As the ends of the link are fed through the plate holes they are bent over,

vices are longitudinally adjustable to accommodate different lengths of links. For similar reasons the device for feeding the links from the link supply guide is divided into two parts one of which is longitudinally adjustable. After the links have been closed upon the plates the drawout mechanism engages each plate and pulls the strand along intermittently. The knockout device disengages the drawout fingers at the end of the feed stroke. This knockout device may be adjusted so as to vary the length of the efl ective stroke. On the return stroke of the'drawout fingers they are retracted so as to pass by the next strand plate. The position of the retractor is also longitudinally adjustable so as to vary the time of engage.- ment of the drawout fingers for difierent lengths of links. The links and plates of the strand are held by the friction shoe-in the strand guide so as to prevent displacement and insure proper, action of the drawout mechanism.
