To all whom it may concern:

Be it known that I, GEORGE E. BIGELOW, a citizen of the United States, residing at l faterbury, in thecounty of New Haven and State of Connecticut, have invented certain new and useful Improvements in stranding- Machines, of which the following is a specification.

sembling links and plates to form strands such as are used inmaking bed fabrics. The

use of the strands formed in my machine is however immaterial and the shape and proportion of the plates and links may be varied without departing from the scope of my invention. Heretofore the links and plates for formin such fabrics have been assembled by han whichis slow and expensive.

It is the main object of my present invention to assemble links and plates into strands which may afterward be connected by hand, or automatically to produce the completed fabric. I have also sought to perfect the details of the mechanism so that all parts work together automatically.

Briefly considered the invention contemplates supplying links and plates to an assembling device, drawing the links. through and thus picking up the plates and interlocking them with the links, and then clos ing the links down on the plates. By the term links Ii intend to refer generally to a member having'an open hook at each end. Such links are usually formed of wire in suitable wire working machines. By the term plate l refer generally to a relatively tlatmember having recesses or periorations in opposite corners. These are usually stamped'square from strips of sheet metal and have four holes, one in each corner, although they are sometimes triangular in outline and supplied with only three holes. The machine illustrated has the as sembling mechanism in duplicate for convenience and economy in construction and operation.-

Fig. 2 is a vertical section on the plane of line X-X Fig. 1. Fig. 3 is a plan view and partial section of the machine.

Fig. -17 is a fragmentary plan view showing details of the tension device.

A suitable frame 1, carries all parts of the mechanism. lhe links are supplied on guides 2, 2 and fed by a rod 3 and intermediate mechanism into chutes 4i, i. The plates are supplied in tubes 5, 5 and fed by a plunger 6 to the assembling point in the front of the chutes i, l. After assembling, the strands are drawn over the bed 7 and beneath a hammer 8 by tension devices 9, 9'. All the moving parts are driven from the main shaft 10 as will be understood hereinafter. One revolution of the shaft completes a single cycle of operations or stroke of the machine. Each cycle adds one plate and one link to each strand. in the particular form shown eachlink 11 is made of wire with a straight shank and hooks 12 and 13 at the ends. Each plate 14 has front and- rear holes 15 and 16 and side holes 1?, 17. The- S ll receive (it column of the links 11, 11, laid sidewise and has vertical coves 18, 18, in which the hooks slide. T e guide 2, has a projection 19, removably fitting in a cone spondinglv shaped recess in the support 20, so that the guide is supported a ove the platform 21, with space enough between to allow for the reciprocation of the tip 22 of the feed lunger 23. A pivoted lever 24, connects tlie plunger with the slide 25. The opposite plunger 23 is similarly connected by lever 24' and reciprocation of the plungers is effected by the reciprocation of slide 25. The in 26 on slide 25 coacts .with the inclined slbt 27, in the end of rod 3, so that when rod 3 is reciprocated by the action of eccentric 28, strap 29, and arm 30, the slide 25, is reciprocated. Each rotation of the main shaft 10, thus causes, through the medium of the mechanism. just described, av

feed of one link from the bottom of the guides 2 and 2 alternately into the chutes 4 and 4 respectively. The mouth of each chute is funnel shaped (Fig. 2.) and being shorter than the length of a link (Fig. 3.) causes the link to turn edgewise and t1p up and fall down the chute endwise (Fig. 4.). The chutes are thus kept supplied with links. The guides may be strung with links in any suitable manner and loaded guides substituted for the empty guides as often as isnecessary. Plate suppZy.The tubes 5', 5 are filled with. the stamped flat plates ,14, 14 which are thus arranged in columns above the path of movement of the feed lunger 6 on the tables 31, 31. The feed p unger is reciprocated, each revolution of the main shaft 10, by means of the eccentric 28, strap 29, arm 32, and lever 33 and a plate 14'is fed from the bottom of each tube to the front of the link chutes (see Sheet 3) so that one corner of a plate projects beyond the edge of the table and into the path of movement of the upper hook 12 of a link (see Fi 12). To permit this, a recess 34, in the front of the link chute is provided, which intersects the link channel 35. AssembZing.-At the end of a stroke of the machine the links and plates are in the relative positions of Fig. 4. As the strand is pulled along, the rear hook 12 of a link enters the front hole of the projecting plate, tilts the plate up and pulls 1t down over the curved end 36, of the table (Fig. 12). The next link in the chute follows; after by .gravity and is thrown forward by the curved surface 37, into the pocket 38, where it momentarily stops. ,At the same moment the front end of the plate 14 catches slightly against the shoulder 39, and the tension on the strand throws the rear end of the plate down to engage the front hook 13 of the link following. The movement of the stroke .behad to the plates and links when 1,oes,eee

slightly to the left of the position shown in .Fig. 13. The plates of the interlocked strand travel in the horizontal groove 40' while the books of the links are guided in the groove 41 and the shanks of the links in the groove 42, the spring 43 servin to hold the parts yieldingly in position. gide movement of the plates durlng the assembling operation is prevented by the guards 44 and 45. The;latter is movable, being clamped by screws 46, 46, so that access may nally starting the machine.

H 0010 closing-AS the two strands travel along the bed 7, the shanks of the links in the grooves 42 and 42, a hammer 8, raised and lowered by rod 47 in the usual manner of stamps on presses, descends and strikes,

at each stroke the two hooks-attached to a plate and closes them as at 48, 48 (Fig. 4 Strand tens-i0n.-The completed stran s pass under friction shoes such as 49 (see heet 4). Each shoe is pressed down 'on the strand plates by springs such as 50, adjustable by nuts 51, 51. Each tension slide 9 is operated by a lever 52 and arm 53 from shaft 10 in a manner similar to the plate feed heretofore described. The slot 54 permits adjustment of the bolt 55 for changing the stroke of the tension device, while the slot 56 permits the relative swinging and slidin movements of lever 52. and slide 9 respectively. The rear end of slide 9 carries two pins 57, 57, which are pressed upward by a spring 58 and adapted to snap into the side holes 17, 17 of a late so as to pull the strand along. The sli e is shown in full in Fig. 15 and dotted in Fi 1 at the left hand end of its stroke. starts back toward the right, the incline or bevel of the pins 57, 57, causes them to be disengaged and allows them tosnap under the following plate and-thence up into its holes for the next tension stroke. To prevent any possible backward movement of the strands I provide stop pins 59, 59 pressed down by spring 60 and beveled toward the rear so as" to permit forward movement of the plates 14, 14 but prevent backward movement. For convenience in construction, adjustment and repair the friction shoes and stop pins are carried by the covers 61, 61 which are bolted or otherwise suitably secured to the frame. The part 62 of the bedwhich lies beneath a shoe 49 is also preferably made separate so that the parts may be readily manufactured and repaired.

. In the mechanism shown, two strands are formed simultaneously and fed out through the grooves 42 and 42 (see Fig. 3). The

feeding of the links from the guides 2 and 2 is effected by alternating the movement of the slides 23 and 23' respectively and the feeding of the plates is efiected by the plunger 6 reciprocating beneath the supply tubes 5 and 5. This arrangement requires a fewer number of parts and is more compact and less expensive to operate than two separate machines. As two strands are being formed side by side they can be readily connected by cross links as they come out from the delivery end of the machine either by hand work or by separate mechanism so as to form a fabric.
