ROPE-MAKING MACHINE.

Application filed December at rope making machine of simple, durable and inexpensive construction.

A further object is to provide in a rope making machine certain improvements whereby very simple means are provided for releasing the longitudinal tension on the strands as they are being twisted, at the will of the operator.

A further object is toprovide in a rope making machine improved means for securing the. fixed ends of the strands, said means being so arranged that the strands may be easily and quickly released or permitted to twist as the rope is being formed, said twisting action being controlled by the operator.

These and other objects are apparent to those skilled in the art.

My invention-consists in the construction, arrangement and combination of the various parts of the device, whereby theob ectS contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which;

2 Figure l ,is a perspective view of my improved device. a

Figure 2 is an end elevation of the twisting mechanism viewed from its outer end.

Figure 3 is an enlarged, detail view of the strand supporting member.

Figured is an enlarged detail view of one end of the body portion of the mechaf nism.

Figure 5 is a perspective view of the strand guide; and

Figure 6 is a detail View showing the strand supporting member in a position as used when the rope is being formed, a portion of the rope also being illustrated.

My improved device comprises a. base board 10 which is designed to rest in a horizontal position upon a box or table, the inner ends of the base 10 being provided with an upright body portion 12, which consists preferably of a board having 5, 1922. Serial No. 605,020.

its lower edge secured to the base and each of its side edges provided with a pair of spaced semi-circular notches 13. Secured to each of the said edges of the body portion 12 by means of screws 14, I have provided a narrow strip 15, the inner edge of said strip being provided with semi-circular notches 16 designed to coact withthe notches 13 so that circular openings may be formed;

Each of the circular openings is designed toreceive a strand twisting hook 17, one end of which is provided with a hook 18 and the opposite end with a crank 19. All of the cranks 19 are designed to receive what I shall term a rotary head 20. The said head is provided with suitable openings to receive the said cranks, the openings being spaced the same distance apart as the openings of the

members

12 and 15.

The central portion of the head 20 is provided with a handle 21. The outer end of each of the cranks 19 is provided with nut 22 or suitable means of securing the rotary head in position.

It will be seen that if the handle 21 is grasped and a rotary movement imparted thereto, that the head will travel in a circular path causing all. of the strand. twistingv hooks to rotate simultaneously.

In the actual manufacturing of this device, the crank and each of the strand twisting hooks are formed before it is assembled. The device is assembled by first removing the screws'l-i and the strips 15,

then placing a strand twisting hook" in each of theslots 13, and afterwards TQPIQC".

ing the strips 15 and securing the same in position. By this arrangement it will be seen that the strand twisting hooks may be very cheaply made by simply forming the hooks by means of a, forming die or drop forging.

For securing the I have'provided a pair .of eyelets 23 in a fined ends of the strands,

post or beam 24, one of the eyelets being spaced above the other in such a manner that a vertically arranged rod 25 may be extended through them. The rod 25 is 'provided with a horizontal portion 26 and an upwardly extended portion 27. The upwardly extending portion 27 is provided at its upper end with a detachable pin 28.

In the practical operation of the device, the base member 10 of the twisting mechanism is placed on a table or box a distance from the strand supporting member 25 s, ac;

slightly greater than the length or the rope which'it is desired 'to make. The center of the body portion 12 is substantially in a horizontal line with the upper end of the member 27. The device is then operated by taking a strand of material from which the rope is to be made, indicated by the numeral 29, and forming a loop in one end, said loop being placed over the downwardly extending-end of the rod 25. The strand is then extended upwardly over one end of the pin 28 to one of the hooks 17. It is then returned to the upper end 27 of the member and passed diagonally over the pin 28, as indicated by the portion 30 of Figure 8. The strand is then carried to another book and brought back again to the member 27. This operation is repeated for each 01'' the books 17, each i which should carry an equal number of strands. The number of strands required is governed by the size of the rope it is desired to make. After a sufiicient number of the strands have been placed on the books, the free end of the strand is brought to the lower end oi? the member 25 and secured in the same manner that the opposite end was. This provides means for rigidly and firmly securing the strands in position.

After the strands have been placed as above described the operator sits on the base and grasps the handle 21 in one hand and imparts a rotary movement'to the head 20. The head may then be rotated sufliciently to cause the strands to twist about each other when released. As the twisting of the strands is being accomplished, the said strands will have a tendency to shorten. This tension may be released by simply permitting the base 10 to slide toward the strand supporting member.

After the strands have been twisted sufficiently, the usual stranc guide device 31 is placed between the strands in the usual manner near the strand supporting member That portion of the strand which is secured to the lower 'end of the member is untied, atter which the member is lifted out of the eyelets 23 and allowed to take the position as shown in Figure 6.

By grasping the portion 27 of the member 25 with one hand and operating the strand guide with the'other hand, it will be seen that the member 27 may be permitted to rotate in the hand as the rope is twisted; or if a very large rope is being made, one operator may grasp the portion 27 in one hand and the portion 25 in the other hand, while another operator controls the strand guide 31. As the strand guide is moved toward the body portion 12, the first oper tor may use the member 25 as a crank and assist in twisting the rope. After the rope has been entirely twisted, the strands may be easily and quickly released from the member 25 by simply pulling the pin 28 from the member 27. The ends of the strands will then slip off of the ends of the said member.

Thus it will be seen that l have provided rope making machine of simple, durable and inexpensive construction which soconstructed and arranged that any person may make his own rope by simply using a few strands of binder twine or similar material.

I claim as my invention.

1. A rope making machine comprising a horizontal base member, an upright body member secured to one end of said base memher, a series oi strand twisting hooks in said body portion, each of which is provided with a. crank, a. rotary head member for said cranks, a handle for said rotary head member, a strand supporting member comprising a pair of eyelets, a supporting rod for said eyelets comprising a vertically arranged portirm having at its upper end a horizontal portion'and an upwardly extending portion for said horizontal portion, and av detachable pin for the last said upwardly extending portion.

2. A rope making machine comprising a horizontal. base member, an upright body portion at one end of said base member, the edges of said body portion being pro vided with semi-circular notches, a strip for each edge of said body portion, each 01? said strips also being provided with semicircular notches to coact with the notches oi said body portion to form openings, means for securing said strips to said body portion, a strand twisting hook for each of the openings formed in said strips, each of said hooks being provided with a crank, a rotary head member for simultaneously receiving all of said cranks, and handle for said head member.

3. In a. device of the class described, a strand supporting member comprising a pair of eyelets, a supporting rod for said eyelets com-prising a vertically arranged portion having at its upper end a horizontal portion and an upwardly extending portion for said horizontal portion, and a detachable pin for the last said upwardly extending portion.
