STRAND OR CORD WORKING MACHINE.

Application filed December 31, 1923.

To all whom it may concern:

Be it known that I, CLARENCE GRIFFITH S'roLL, a citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Strand or Cord Working Machines, of which the following is a full, clear, concise, andexact description.

This invention relates to strand or cord working machines, and more particularly to a machine for binding a plurality of strand materials together.

An object of this invention is to provide a machine which will be eflicient in operation and so compact in structure as to substantially increase the productive capacity of the floor space occupied by the machine.

A further objectof this invention is to provide a machine so designed that the strand is drawn from the strand supplies and through the strand working devices and stored on the take-up devices with a minimum amount of bending thereof and with no deleterious friction or wear thereon.

In its preferred form the invention consists of a single unitary frame upon two opposite sides of which is mounted a pair of independently operable strand working de vices. Associated with each strand working device is a pair of strand supplies arranged therebelow, side by side upon the same side of the frame and at an angle whereby the feed of the strand therefrom is focused on a guide positioned below the strand working devices. Mounted above and on a line intermediate the devices and each pair of strand supplies is a pair ofconcentric capstans of comparatively large size, one for each of the strand working devices, whereby the strand is subjected to a minimum amount of bending. The capstans operate in opposite directions to draw the pair of strands from each of the associated strand working devices and direct the worked strands to suitable guides and then to a storage device disposed below the strand working devices and upon that side of the machine upon which the strand supply for the opposite strand working device is positioned. Means, re-

sponsive to the tension on the strand material traveling from the capstans to the associated storage devices, is also provided for regulating the speed of the aforementioned storage devices and thereby maintaining a substantially constant tension on the strand between the said capstans and strand storage devices.

It will be apparent, however, that the features of this invention are readily applicable to other mechanisms and are not limited to their use with the apparatus disclosed.

Other objects and advantages of the invention will more fully appear from the following detailed description taken in connection with the accompanying drawings, in which Fig. 1 is a front view of the machine;

Fig. 2 is a view taken from the left-hand side of Fig. 1;

Fig. 3 is an enlarged vertical detail sectional view taken through the supply spool mechanism Fig. 4 is an enlarged vertical sectional view taken on the line H of Fig. 3 looking in the direction indicated by the arrows, and

Fig. 5 is an enlarged vertical sectional view of the capstan mechanism.

Referring now to the drawings in detail in which like reference numerals designate similar parts throughout the several views, 10 is a machine frame on which is mounted four complete binding units, two on each side of the frame. Each binding unit comprises four sub-units, a supply spool unit 11, a serving or binding unit 12, a capstan unit 13, and a take-up spool unit 14. These sub-units are mounted independently of each other in such a way that any one can be removed without disturbing the others.

Suitably located in the lower part of the frame 10 is a motor 15 which drives all four units through the medium of one main or common shaft and suitable intermediate gearing (not shown).

As shown in Fig. 2 the wires 16 are fed from the underside of the supply spools 17 and 18 to a guide 19 located in binding sub ell) ' whereas unit 12. The spools 17 and 18 are mounted at an angle with their heads adjacent, on a rotatable member 21, (Fig. 3) thereby enabling the strand materials to be withdrawn therefrom with a minimum amount of friction, the feeding angle of the strand materials being focused on the guide 19 (Figs. .1 and .c.%eeured to a stud which is suitably attached to the lower part of the frame 19, is a stu l 28 upon which the member 21 rotates. Located on top oi? the rotatable member 21 is a small cam lever 25 pivotally secured to a loci-t pin 26, which extends through the rotatable member 21. As best shown in Fig. A the rotatable member 21 is locked against rotation through the engagement of the end of the lock pin. 26 in an opening 2'! in the stud Formed around the lower part of the lock pin 26 is a small collar 28 which lits snugly in an enlarged opening 29 in the rotatable member 21. Between the collar 28 and upper part of the opening 29 is a small compression spring 30, which upon the operation of cam lever to loci; the rotatable member 21 causes the lock pin to be forced into its locked posi ion. By unlocking the member 21 and rotating it and the spools attached thereto on the stud 22 the operator enabled to expeditiously unload and reload the strand spool carrying member 21.

A chain 32 (Fig. 13), which is attached at one end to a l 33, passes over a grooved pulley which is mounted in a bracket secured to the fre ne. lhe other end of the chain 2 which passes over pulley 3 1, is attached to a. weight 36. A small length of chain passes over the grooved pulley 3 1 being secured at one end to a handle 38.

t1 e other end is also secured to the weight 36. The r ight 36 causes the chain to be drawn taut, drawing up the lever 32 which in turn causes a lever saaft '1 to turn. The lever sha'tt l1. which is meanted at one end in a support -2 in turn operates a series of levers. which causes a shoe l?) to be pressed against the material on the supply spool thereby preventing the material from overrunning the spool and also tending to maintain a constant tension on the strand being withdrawn. By drawthe handle 38 and placing it. in :1 -11 n'ionnted on the frame 10 the 1 33 drops of its own weight, causing the shoe 43 to also drop.

The wires 16 to be bound together are ravn from the supply spools 17 and 18 irough the guide 19, serving head 45, cop magazine brackets -l-6 and cops a? by a power driven capstan 18 located in the capstan unit 13.

As shown in Fig. 5, capstan unit 13 consists of two concentric capstans 18 and 19 of the same diameter, having interlocking flanges and rotatable in opposite directions.

The capstan bearing housing 50 in which the capstan mechanism is located is secured to the frame 10. Keyed to the end of a vertical shaft 51 is a bevel gear which is meshed with a bevel gear 53. l he bevel gear 53 is secured to a capstan shaft sleeve 5% by a key 55. Keyed to the vertical shaft 51$ is a bevel gear 5? which is meshed with a bevel gear The bevel gear 58 is secured to a capstan shatt 59 by a key 60. t eparating the two bevel gears 5-8 and 53 is a shoulder (31 on the capstan shaft 59 and two thrust collars 62 and 63. The capstan shaft 59 revolves in the capstan shaft sleeve Bl and bearing (31, while the capstan shaft sleeve revolves around the capsl an shaft 59 and in the bearing 65.

Located on the capstan shaft sleeve H are two thrust washers (58 and 69. A thrust washer 1 0 on the capstan shaft 59 separates the hubs of the capstais 4:9 and 4L8. The capstan 1? is secured to the capstan shaft sleeve by hey 71 and the capstan 4:8 is secured. to the capstan shaft 59 by a key 7 2. Two lock nuts 73 and '71 on the end of the capstan shaft 59 retain the two capstans 18 and :19 in their respective positions. Located throughout. the capstan bearing housing 50 are oil feeds, such as 75, T6 hnd 7. A thrust washer T8 fits around the capstan shaft 59 and between the housing 50 and the bevel gear 58. The vertical shafts 51 and 56 revolve in the bushings (36 and G7 and the bearings 79 and 80.

Suitably located in each unit is a tension assembly 81 which is responsive to the tension on the strand material traveling from the capstan sub-unit 13 to the take-up spoo s.d -unit Iii: and adapted to thereby 1 i (e the speed o the said take-up spool sub-unit ll, thus n'eventing any undue ten- Sic-n upon the strand.

fa tension mechanism of this type is more fully dipclosed in detail in patent to F. 8. line cndorler et al.. No. 1.520518. dated De cemln 2% 192-1, to which reference may be had for a full description of the operation tlu :of

A lever 86 operates a disc clutch (not shown) associated with the driving mechanism of one complete unit. By operating this lever the mechanism of that particular unit can be stopped without interfering with the other three units.

The machine above described, having a pair of independently operable strand work ing devices upon two opposite sides there of with a pair of comparatively large diameter capstans for each pair of devices arranged concentrically thereabove for drawing the worked strand therethrough pro- 'vides a machine which has great productive capacity for the floor space occupied thereby. The concentric mounting of the capstans reduces the floor space occupied by the machine compared to a similar machine having each capstan mounted upon a separate shaft where the capstans are of the same diameter in both instances. Also due to the comparatively large diameter capstans and the angular mounting of the strand supplies below the strand working devices for focus ing the strands upon the guide positioned below the strand working devices, the strand is drawn through the strand working devices and around the capstans and stored on the take-up reel with a minimum bending thereof, and with no deleterious friction or wear thereon.
