MACHINE FOR PREPARING DRIVE-CHAINS FOR SHIPMENT.

SPECIFICATION forming part of Letters Patent No. 443,303, dated December 23, 1890.

Original application filed October 21 1885, Serial No. 327,732. Divided and this application filed February 18, 1890. Serial No. 7

To all whom it may concern.-

Be it known that I, J AMES DOUGLAS Sronrn, of the town of Oshawa, in the county and Province of Ontario, Canada, have invented a certain new and useful Improved Machine for Preparing Drive-Chains for Shipment; and I do hereby declare that the following is a full, clear, and exact description of the same.

Thisinvention is intended to provide a simple and effective means of dividing up the long lengths of chain kept in store in coils into smaller lengths, in which such chain is usually purchased, and of winding the same into compact coils for shipment.

The measuringdevices consist of aspindle, upon which the large coil is mounted and can be rotated, and anumber of pins at a distance from the spindle, in connection with a table (preferablyhavingmarked onitssurfacescaledivisions corresponding to the different sizes of links in different chains) on which the smaller lengths will lie, the end of the large coil being drawn to one of the pins and any specified length in links of the portion of chain thus unwound disconnected from the main length. For compactly winding the lengths thus measured off, an adjustable yieldingresistance device operates, in connection with a winding-key similar to that shown and claimed in a contemporary application, Serial No. 327,732, filed October 21, 1889, for Letters Patent, and nowpending, of which application this present one is a divisional part, such key consisting of a vertical spindle having a headpiece that projects through an opening in the table, and which also has a vertical slit in it to receive the end link of the chain, and has its sides configurated to suit the shape of the center of the coil formed by the straight surfaces of, say, the first three or four links encircling it, the shape being approximately quadrangular. For full comprehension, however, of the invention reference must be had to the annexed drawings, in which Figure 1 is a plan view of the machine, a coil of chain being indicated on the spindle by dotted lines; Fig. 2, a similar view showin g a length measured off; Fig. 3, a front View of machine. Fig. 4: is a view of part of under side of table; Fig. 5, a vertical cross-see tion of machine; Figs. 6 and 7, details of parts of yielding-resistance device; Fig. 8, a detail showing winding key or spindle depressed below the level of the table, and Fig. 9 an enlarged detail of head of said spindle.

Like symbols indicate corresponding parts.

A is the table, suitably supported by legs A and having openings a a an aperture a" and slot u in its surface.

'1 is a horizontal bar or spindle projecting at a convenient height across the table from a support T, situated about centrally of the machine and at the rear thereof, and t t are pins arranged at the right-hand end of the table.

To measure the lengths of chain from the large coil in store, this coil is slipped onto the spindle T, and according to the length of its links corresponding with one of the scaledivisions marked on the table it will be pushed along the spindle into line with such particular scale. The operator now takes the outer end link of the coil and unwinds (by pulling and so rotating the coil) till he is enabled to fit such link over the pin at the end of the scale, and this being done he detaches the portion at the desired point indicated by the scale.

As will readily be seen, the measurements are not confined to small lengths, as an entire coil could be measured by unwinding the coil in portions the full length of the particular scale and keeping count of the number of measurements made, the measured portion of the chain being allowed to fall over the end of the table. This, however, is very seldom required to be done. Of course it is not necessary to have the scale-divisions marked permanently on the surface of the table, as the operator could simply count any desired number of links backward from the end one fitted on a pin, make a chalk mark on the table at the required point, and then proceed to measure off a number of lengths without further counting.

Having disconnected the short lengths required, as before described, it now remains to rewind them into separate coils as compactly as possible for shipment, and to do this the winding and yielding resistance mechanism now to be described is used. The winding mechanism consists of a key or spindle made up of a head-piece J to project through the aperture a in the table and above the surface of the same while winding, having a slit in it, as shown in Fig. i), to receive the end link, and its sides configurated to suit the shape of the center of the coil formed by the straight surfaces of, say, the first three or four links encircling it, the shape being approximately quadrangular. For dillerent sizes of links di'lferent-sized heads with same configuration must of course be used, and, as shown in Fig. 5, the arrangement is such that they can be screwed into the top of the plunger, preferably formed in two parts J J screwed together, of the spindle. The plunger rests on a spring J, confined within a sleeve J", which carries the pulley ll, encircles the plunger and serves to rotate it through a pin J projecting from the same into a slotj in the sleeve, this slot also serving to regulate the upward movement of the plunger. The spindle secures a vertical hearing in a recessed foot-plate for the end of the sleeve J and a boss on the under side of table A for the upper part J of the plunger.

J is a lever pivoted atj" to a hanger from the table A, slotted to encircle the part J" of the plunger and bearing when it is desired to depress same upon a collar J, secured beneath it to the part J. This spindle will be rotated by a band from any convenient shafting to pulley ll and under control of clutch mechanism, with which lever Q can be connected.

The mechanism for compacting the coil as it is wound consists of a roller X, mounted on a vertical spindle U, which projects up through slot u in the table from a slide U, having bearings in guidcways on the under side of the table. The function of this roller in connection with such slide is to furnish ayielding pressure upon the coil while being wound, and I have shown a means of ctlecting such a pressure and of regulating the ex tent of its application.

U are what may be termed whillletrees or frames, (shown in front elevation and section in Figs. (3 and 7,) to which and to the slide U are connected the ends of strong retractile springs U. These frames are pivotally connected by screws a with nuts U, arranged to travel on adjusting-screws U, carried in suitable bearings, and provided with crankhandles operated through the openings a (1 When a chain of very small lengthis to be wound, the roller X will of course need to be brought at the start in close proximity to the winding-key, and when alonger one it will be moved farther away.

There is no other connection between the whifiietrees movable by the adj IISiLi-llg-SCIGWS and the slide than the springs U but their retractile force is such as to condense their coiling to a stability sulticiently rigid to impel the slide and roller in a direction from the key, when desired, without collapsing in the smallest degree. It will now be seen that when the roller X is properly located and the length of chain turned up on edge with one end link inserted in the slit j the machine is started and the chain wound around the key, receiving at the same time the pressure of the roller, which increases as the end approaches. As eachcoil is finished the lever is depressed so as to lower the head-piece J beneath the table-surface, and so free coil, which is removed, and has its outer end secured in the usual. way, leaving it ready for shipment.
