MACHINE FOR MAKING CHAINS.
Application filed. June 17, 1908, Serial No. 439.037.
T 0 all whom it may concern:
Be it known that I, LACHLAN E. McKin- NON, a subject of the King of (iIQHt Britain, of Erie and State of New York, have invented a new and useful Improvement in Machines for Making Chains, of which the following is a specification.
This invention relates more particularly to machines for joining or interlocking and closing partially formed open chain links to form the chains.
The invention is herein described in connection with a machine for making chains composed of straight oval links with lapped ends which are afterward welded. but the invention isalso applicable to machines for making other styles of chains in which the links interlock at an angle to each other.
The object of the invention is to produce an etlicient and desirable machine of very simple construction for rapidly interlocking and closing the partly formed open links.
The machine is provided with magazines or stack-holders which support the partially formed open links flatwise in two stacks, with the links of one stack approximately at right angles to the links of the other stack. A link is fed first from one stack, closed end foremost, into a guide device which supports the link with its open end uppermost or rearwardly with respect to the direction of travel of the link through the machine. A second link is fed from the other stack, closed end foremost, into the guide and between the separated ends of the first link and is temporarily supported in a plane at rightangles to the plane of the first link and with its open end uppermost or rearwardly. The first link is then advanced between devices which press or close its open ends toward each other and pass the ends through the loop of the second link. In the advance movement of the first link its ends are closed together and engage the closed end of the second link and draw it between the closing devices, so that its open ends are closed together through the loop of the next following or third link which has in the meantime been fed from the first stack into the guide between the separated ends of the second link and is temporarily supported by the guide at right angles to the second link until engaged by the second Specification of Letters Patent.
link and drawn between the closing devices.
Patented June 10, 1913.
Renewed November 18, 1912. Serial No. 732,133.
The links are thus fed alternately from the two stacks into the guide and drawn in suc cession through the same between the closing devices which interlock and close the links, making a continuous chain. In thus interlocking and closing the links it is not necessary to twist or turn either the chain, the links, or the devices which interlock and close the same.
In the accompanying drawings, consisting of three sheets: Figure l is a longitudinal sectional elevation of a chain-making machine embodying the invention, in line 1--l, Fig. 5. Fig. 2 is a fragmentary plan view, on an enlarged scale, of the feed table and guide for the links. Fig. 3 is a fragmentary sectional elevation thereof in line 3 3, Fig. 2. Fig. 4 is a perspective view of one of the closed links detached. Fig. 5 is a plan view, partly in section, of the machine. Fig. 6 is a sectional plan thereof in line (3(-3, Fig. 1. Fig. 7 is a transverse sectional elevation thereof, in line 7-7, Fig. 5. Fig. 8 is a fragmentary section, on an enlarged scale, of the lower portion of one of the link magazines. Fig. 9 is a sectional plan view, on an enlarged scale. of the link closing rollers or devices. Fig. 10 is a sectional view, showing a modified construction of the closing guide.
Like reference characters refer parts in the several figures.
The links are bent into a preliminary shape so as to be closed at one end and open at the other, as shown at X, Figs: 1, 2 and 5, in a suitable machine before they are placed in the machine herein described. which interlocks the links and closes or presses their separated ends together, as shown in Fig. 4. A portion of the chain is shown in Fig. 1. In the particular style of link illustrated in the drawings the sc iiarated ends of the link are hook-shaped and overlap when closed.
A represents a frame of any suitable construction having a horizontal top or table a, and 13 a feed plate which is fastened by screws. or otherwise, on the table. The open links X are placed fiatwise in two upright magazines or stacks on the feed plate with the links in one stack substantially at right angles to those in the other stack. as shown in Fig. 5, and are so retained by suitable means, such as magazine or stack holding bars I) and E which are supported in upright position over the feed plate by a .a link fed from one stark and bracket 0 secured to the table a or other suitable means. The lower ends of the magazine bars are spaced just far enough above the feed plate to allow the links to be ted one at a time from the bottom of each stark Without disturbing the other links, by a feed plunger or device which reeiproeates beneath the magazine bar.
. As the two side bars of a link are not directly opposite eaeh other in the same plane but are twisted somewhat in opposite direetions to enable the hooked ends to overlap when pressed together, the link will not lie flat upon a plain suri'are but one book will be higher than the other and the link will Wabble more or less, whieh would cause the links to interfere and prevent the proper feeding of the same from the staeks. To cause the links to lie steadily with the high points of their hooked endsv in the same horizontal plane and thereby insure the proper feeding of the links singly from the staek the upper face of the feed plate is preferably grooved at f f beneath eaeh magazine bar in the direction of feed of the links from the stack and the ends of the links lie in these grooves, which steady the links and guide them when pushed from beneath the stacks. This formation of the feed plate requires the Stacks of links to tilt laterally somewhat from the vertical, as shown in Fig. 7, and the magazine bars I) and l) are theretore eorrespondingly tilted from the vertieal.
represents a guide opening or passage extending through the table at the interseetion of upright planes extending through the staeks of links in the direction ol' teed of the links from the staeks, so that when a link is pushed oftthe l'eed plate from either stuck it will tilt downwardly and tall in upright position into this guide opening. The guide openingis substantially erueil'orm in shape and eontraets downwardly, its widel portions being of slightly less width than the upper flaring portion of the link, so that dropping therein will be supported in an 'u 'iright position, and in a plane at right angles to a'link ted from the other stark and dropping into the opening, as shown in .l"igs. l. 2 and 3.
The links are fed alna'nately from the two stacks into the guide opening by suitable means whieh, in the niaehine illustrated, ron sist of feed plungers ll and l whieh are reciproeated horizontally between the teed plates and the lower ends ol' the magazine bars in direelions at right angles to well other. llaeh plunger enga res and l'eeds the lowest link from its stark at eaeh advanee movement. I has a eenlral l'r nt extension whieh enter between the separated ends ot the linlq and assists the grooves f of the let-rd plate in guiding the links when ted forwardly l'r-mu the slneks. The te d plungers ll and l are lla h l'eed plung r pr l ahl v.
mounted upon slides i, respectively. Figs. 1 and 7, which are movable horizontally in guide ways 1L2 and i in the table a. The slide /i has a lug depending through a slot. in the table, Fig. l, and eonneeted to the end of a rock arm Z. on a horizontal shaft K whieh is journaled beneath the table in a l *aring la and is provided with a ei'ank arm 7., Fig. (3, eonneeted by a pitinan to a erank wheel [on a horizontal shaft L whieh is jonrnaled beneath the table in bearings Z. This shaft L is provided at one end with a belt pulley Z and eonstitutes the dri\e shaft for the maehine.
M represents a horizontal shalt whieh is journaled beneath the table at right angles to the drive shatt L in hearings in and is driven from the drive shaft by bevel gear wheels m m Fig. (l. erank wheel m seeured to one end of the shall M is eonneeted bya pitinan m to a lever in, Fig. 7, whieh is tulerumed on a braekel m projeeting from one side of the table and is eonner-ted by a link m to the slide 1." of the teed plunger I. By this meehani m one teed plunger is iulvaneed while the other l'eed plunger is retracted, so that the links are ted alternately first from one stark and then from the other.
hen a link is fed from one slaek it drops with its elosed front end into the guide opening and is supported thereby with its open rear end uppermost. and when a link is fed lronnthe other stark it drops with its elosed front end into the guide opening and between the separated ends of the first link and is supported by the guide opening in a plane at right angles to that of the tirst link and wi h its separated ends uppermost, as shown in l igs. l. I; and T. llaeh link thus drops between the eparated ends ot' the preceding link in a position in which the separated ends of the foremost link will be pa sed through the next t'ollowing link in elosing the foremost link. liv drawing the links in sueeession through the guide opening the separated ends of the links are sueeessively ])i(f. f-.(ll or elosed together, whereby the links are interloelmd or joined together in a ehain.
The deseribed meehanisin for feeding the links alternately in directions approximately at right angles to eaeh other from the bottoms of two staeks or magazines into the guide opening is simple and eliicient but the invention is not limited to this partieular means for l'eeding the links and other means ma) be employed.
The means tor closing the links to interlork them prelerabb ronsist ol' grooved rolls N arranged in two pairs below the "Jnid openinp (i in the table. The pairs cil' iull are lorated in vertieal planes at right angles to eaeh oth r in sueh manner that one link \till pass. from the guide open ing ti beturrn the rolls it one pair with its ide bars bearing in the grooves oi the rolls,
and the next link will pass in a similar manner between the rolls of the other pair, see Fig. 9. The rolls of each pair are spaced apart such a distance that by drawing the links between them the rolls wlll press or squeeze the side bars of the links toward each other to cause the hooks to overlap and close the open ends of the links. The rolls can be mounted in any suitable manner, being, in the construction shown, supported by axles which turn in journal blocks n secured by bolts n in a rectangular recess in the under side of the table a. When a link is dropped into the guide opening its lower closed end will enter the space between the rolls of one pair and the next following link will occupy a similar position between the rolls of the other pair. When the first mentioned link is drawn between its pair of rolls its separated ends are gradually closed together through the loop of the following link and caused to overlap. As the movement of the first mentioned link continues its lapped ends engage the closed end of the following link and draw the latter between its rolls, whereby its separated ends are interlocked with the next following link and closed. Thus each link when it IS closed and advanced engages and advances the succeeding link and causes it to be closed. The rolls arranged in this manner constitute exceedingly simple means for closing the links and they form in effect anti-friction or rolling continuations of the guide faces of the opening G through which the links pass. The guide opening itself can have its working faces so shaped and proportioned as to act, not only as a guide to properly position the links, but also as a die to close the links as they are drawn through it, which construction is represented in Fig. 10, but the rollers are preferable as they close the links with less draft on the chain. The links could, however, be successively closed as they are advanced through the uide by other means without changing the principle of operation of the machine.
A sprocket wheel 0, Figs. 1 and (i, is shown for pulling thechain to d'aw the links through the passes of the link-clOsing rolls. This sprocket wheel, which has teeth suitably arranged to engage the links of the chain, is secured to a horizontal shaft p which is journaled beneath the table in a bearing 79, and is driven at the proper speed by suitable means, such as a train of gears 1 (1 (1 connecting it with the main drive shaft L. Other means could be em ployed in place of the sprocket wheel for pulling the chain to move the links past the closing device. The chain can pass from the sprocket wheel or other draft device to a Windlass or reel, not shown, for taking up the chain as it is produced.
The closin 1 means or die maintains at all times a fixe or stationary relation to the link magazines which are arranged in converging or intersecting planes, and in assembling and closing the links the latter are fed into the closing means or die alternately in two intersecting planes and are closed by a straight progressive movement through the closing means or die, without requiring a rotary or twisting movement about the axis of the closing means or die, either in the latter or in the links or chain.
