I V a I8 V I 18 i H 15 Q r Q I3 A T 22 r 1 l6 [N VENTOR RAY HOOVER @mfj w TTORI Patented Nov. 5, 1935 UNITED, STATES PATENT OFFICE TAPE WINDING REEL Application April 1, 1932, Serial No. 602,560 9 Claims. ((1242-40) This invention relates to winding and reeling mechanisms, particularly to an arrangement for winding or forming a coil or reel of material within a container removably mounted about a reel, which container may be transported from the place of winding to some other place where it is desired to unwind the material.

The principal object of this invention is to provide means whereby material in the form of tape or other linear conformation can be wound on a reel encased in a container whichrnay be removed from about the reel, said coil of material being removable simultaneously with the container and retained within container in wound form.

Another object of this invention is to provide container means for transporting coils of material in the form of tape or the like from a point of accumulation to another point at which it is desired to utilize the material.

A further object of this invention is to provide an arrangement for unwinding the reel or coil with the material traveling in the same direction as when it was wound upon the coil, that is, by 25 withdrawing first from the coil the same end of the material which entered the coil at the beginning of the winding operation.

A still further object of this invention is to provide means to mount the container on a base or stand which will permit the material to be unwound freely from the coil without removing the coil bodily from the container.

Other objects of this invention will appear as the description proceeds. I

While this invention may be applied to the handling and transporting of various types of material, it is particularly adaptable to handling material in the form of tape or thin flat strips. As a specific example, this invention may be employed in connection with the transporting of tapes employed in connection with telegraph apparatus in which a tape may be perforated or incoded by one telegraph machine situated in one location and decoded or employed to operate a. transmitting machine situated at a distant location, in which case the perforated or coded tape is permitted to accumulate at the first machine until a certain mes-age, a number of messages, or portions thereof, have been incoded on the tape when it is detached from the machine and transported bodily to the transmitting machine or point where it is to be decoded. In such a systern of operation the problem arises of accumulating the tape in a form in which it can be easily transported and transporting the same without damage and also of making the tape available at the point in which it is to be employed for decoding or retransmitting the mes sage incoded thereon in such a manner that it may be permitted to unwind from the coil freely 5 at the required speed.

According to this invention an arrangement is provided which will meet the above requirements for handling a tape under these conditions. Ac cording to the preferred embodiment of this in- 10 vention a reel is mounted upon a stand with means for driving the reel to wind the tape as it accumulates from the perforating or incoding apparatus. A transportable container is mounted to form a circumferential enclosure about the 15 reel providing a space within which a spiral coil or reel of the material may form about the fingers of the reel mechanism as it rotates. A slot or opening is provided in one side of the container for permitting the tape to enter the container 20 and become wound about the fingers of the reel. The container is provided with suitable openings or recesses which permit it to be withdrawn laterally of the reel and it also includes suitable projections in the back side of the container 25 which engage the coil of material and strip the same from the fingers of the reel as it is removed therefrom. A suitable cap is provided for covering an outer opening in the container. The cap has axially extending fingers which engage the coil of material and maintain the same substantially concentric in the container. When the cap. has been put in place the container may then be transported readily by any suitable means to the location of the desired sending or decoding apparatus.

when it is desired to feed the material from the coil into the sending apparatus it willbe observed that the material will necessarilylbe required to travel through the sending apparatus 0 in the same direction as through the perforating or incoding apparatus. It will be observed also that when the coil is formed the forward end of the material is first wound upon the fingers of the reel and forms the center portion of the coil. 45 When this coil of material, now arrives at the unwinding position it is necessary to either rewind the coil of material in a reverse direction or to provide an arrangement for feeding the tape of material out of the coil so that the center portion of the coil is unwound first with the unwinding proceeding from the center outward. According to this invention it has been found that the rewinding step can be eliminated by providing a cone upon a suitable stand or base over which 55 22 into the container.

the container is positioned, the cone entering the opening or core at the center of the coil of matrial and providing a stem around which the material will rise after the inner end has been pulled sidewise from the center of the core and drawn forwardaround the stem or cone.

For a further description of this invention reference may be had to the accompanying drawing in which:

Fig. l is a view partly in section showing a reel rotatably mounted upon a stand and the container in position over the reel to receive the material as it is wound thereon;

Figs. 2 and 3 are front and rear elevations respectively of the arrangement illustrated in Fig. 1;

Fig. 4 is an expanded view of the apparatus illustrated in Figs. 1 to 3 with "the container removed from the reel stand and the retaining cap in position to be placed on the container; and

Fig. 5 is a view illustrating the container mounted for unwinding the material therefrom.

Referring to Figs. 1 to 4 the preferred embodiment of this invention comprises a stand or support ll carrying a shaft ll upon which a reel I2 is rotatably mounted. A suitable crank I3 is secured to the shaft for driving the reel. It is to be understood that the reel may be driven by any suitable type of motor instead of the crank such as a spring motor provided with suitable means to connect it to the shaft or an electric motor suitably connected to the shaft and provided with proper control means. In such a case the stand l may be displaced by the frame or supporting members of the motor. The reel l2 comprises a suitable hub ll fitted to the shaft H and a plurality of arms I! preferably four in number extending outward from the hub and carrying Pins or fingers l8 secured in the outer end of the arms and arranged parallel to the shaft l I. Each of the fingers I6 is slotted in a radial direction so that the end of a tape such as the tape I! may be inserted in the slot of any one of the fingers to hold the end of the tape at the begin ning of the winding operation.

A cylindrical container or casing I8 is arranged to be mounted upon suitable supporting members I! and fl in a position concentric with the reel for forming a circumferential chamber about the reel which will enclose .a coil of the tape I! as it is wound upon the reel. The length of the container will be determined by the width of the tape material which it is desired to em close. The ends of the cylindrical container are preferably formed of fiat circular members. The rear end of the container is provided with an opening or recess 12 conforming somewhat to the star shape of the reel determined by the outwardly extending radial arms so that the container may be mounted in position over the reel by permitting the reel to pass through said opening The forward end of the container embodies a circular opening 23 preferably of a diameter which will permit the outward end of the reel fingers i6 to extend into the opening whenthe container is mounted on the stand "I. The opening 23 is especially employed in connection with withdrawing or unwinding the tape from the reel as will be explained in more detail in connection with Fig. 5.

It will be observed that the star-shaped opening in'the back portion of the container embodies segments 24 which extend inwardly out of the position of the fingers l6 suificiently to reach beyond the inner edge of a coil or reel of tape wound that the container be held in a definite position with relation to the reel before it can be moved into proper position. In order to facilitate the positioning of the container with respect to the reel, suitable means for holding the reel in a predetermined fixed position is provided comprising ratchet wheel 25 with an engaging pawl is arranged with the ratchet wheel fixed to the shaft II and the teeth in such position that when any one of them engages the pawl the arms of the reel will be in a definite angular position. In this manner the casing can easily be positioned so that it slips readily into place over the arms of the reel. When the container is slipped in place over the reel it envelops the reel so that it is necessary to provide an opening 26 in one side ofthe container for admitting the tape or other material to be wound thereon. This opening is cut in the form of a slot entirely through-the outer end or face of the container and along its circumference to the rear end. This arrangement enables the end of the tape to be slid sidewise into proper place to feed through the container to the reel, and if in proper alignment with the slot embodied in one of the fingers l8 will pass simultaneously into position in said slot. 39

Usually the perforating machine or other source of the tape is disposed in a definite relation with respect to the position of the winding reel. It is. therefore, desirable that the slot 26 in the container-shall be positioned nearest the source of the tape. In order to provide for both of these features, means is embodied in the stand structure I 0 to form a detent means so that the container may be rotated after it is placed upon the stand to a certain position when the detent will 40 engage a recess in the container and hold it in the desired position. This detent means may be provided by a spring 2. mounted on the stand embodying a pin 28 arranged to drop into a corresponding hole III in the container when the container is rotated so that the hole passes in front of the pin. When the container is first inserted in position the spring is pressed backwardly toward the stand maintaining the pin in engagement with the back of the container until it is brought into retaining or detent positionby r tating the container.

After the container has been located in the proper position the tape II to be reeled may be inserted through the slot :6 of the casing and through a slot in one of the reel arms i6 and the end of the tape bent over or otherwise suitably secured in theslot. The reel may then be rotated in a counterclockwise direction looking at the front of the container until a coil of tape has been formed about the fingers of the reel. As may be observed by referring to Fig. 1, this coil of tape will extend out into the circumferential chamber formed about the reel by the container it. The coil of tape is removed from 05 the reel when the container is withdrawn from the support in a direction longitudinal of the shaft of the reel. The removal of the tape is accomplished by the back portion of the container and particularly the segments 24 of the back portion coming into engagement with the coil of tape between the arms ii of the reel.

As the-container is withdrawn a cap 3| as illustrated in Fig. 4 to be snapped into place over the opening 211s brought into position and the A likelihood of-the coil becoming 'tion of the coil.

tape being withdrawn may readily rise from the fingers or arms I! extending from the cap to ward the container are inserted into the central opening in the reel of tape formerly occupied by the arms ll of the reel. With the container entirely removed from the support and from about the reel and the cap 3| snapped into position. the fingers 82 will serve to keep the coil of tape substantially centered inthe, container and will effectively prevent the coil from falling out through the openings in either the front or rear end of the container. After the coil has thus been enclosed in the container it may be readily transported fromonelocation to another without damage to the tape or without the unwound or entang edim After the tape has been transported tothe desired destination it must .then be unwound so that it may be fed. into the decoding or transmitting machine. Ordinarily in order to feed the forward end-of thetape first into the machine it would be necessary to rewind the coil of tape so that the forward end would appear at the outside of the coil. However, an arrangement similar to that iilustrated in Pig. 5 eliminates the necessity for the rewinding operation and makes it possible to effectively unwind the forward end of the tape from the center of the coil in which position it appears the coil is first formed. The unwinding of a perforated tape which is weakened considerably due to the perforations therein, must occur very smoothly in order to eliminate any possibility of the tape hanging and causing rupture thereof. The mechanism illustrated in Fig. 5 has been found very effective and has already gone into extensive use The unwinding apparatus comprises a base I! upon which a spindle I8 is rotatably mounted.

At the bottom end of the spindle a disk 31 is secured upon which the container it rests when located on the unwinding mechanism. The inner ends of the segments N of the casing I I, as illusthe inner ends of the segments .24. The shape of the spindle It may be of other forms than that illustrated, as 'for instance a straight conical member in which the largest diameter is at the foot of the spindle. When the type of spindle illustrated is employed it is necessary to provide a centering plate It arranged to engage the inner ends of the segments II. As illustrated the spindie 80 is provided with its largest diameter substantially at the upper edge of the coil of tape II. From this point upward the surface of the spindle recedes toward the center. As shown in the illustration this surface is spherical but it may be either conical or any other shape which presents a receding surface. The purpose of the receding surface is to permit the inner end of the tape which is being withdrawn from the center of the coil to ride upon the spindle and easily slip upwardly as it approaches the rim of the opening a at the top of the container. The opening a is of a substantially larger diameter than the largest diameter of the spindle in order to provide an annular opening through which thetape may easily pass. As the inner end of the tape rises to pass over the rim Ila of the opening 23 there is a tendency for the tape to twist at the point where it begins to rise from the inner por- If the coil is loosely wound the center of the coil when a substantially conical spindle having its largest diameter at its lower end is employed. on the other hand, if the coil of tape becomes tightly wound the tendency of the tape to twist as aforesaid will cause binding between the inner side of the coil of tape and the spindle as it tends to rise. It has been found that by undercutting or tapering the portion of the spindle extending through the coil of tape. to provide room for the rising portion of the tape to twist, as it has a'iendency to do, the possibility of the tape binding if the coil is wound tightly 1. Practically eliminated.

In the unwinding operation as above described the spindle I! performs several functions. The first of these is to keep the coil of tape centered in the container so that it will properly feed out through the opening 28 in the top of thecontainer. The second of these functions is to provide a member on which the tape can ride or roll as the thickness of the coil is reduced. Still another function of the spindle 38, particularly,

when it is provided with a surface decidedly'receding toward the center such as the spherical form illustrated, is to permit the tape to be twisted substantially into the horizontal plane 30 with the outer surface of the coil convolutions uppermost-permitting the tape to be withdrawn in a' substantially radial or horizontal direction. This twist is clearly pictured in Fig. 5 of the drawing. When the tape is withdrawn from the coil in this manner-no dimculty is experienced in the tape tending to bind upon the inner convolutions of the coil. The unwinding of. the cal proceeds with a smooth and free movement.

From the foregoing description it will be seen 4!) that a method and apparatus is provided for winding a coil of tape within'a container which may be transported from place to place and furnish protection to the tape during the time of transport, and-alsowhen the tape has reached its destination and it is desired to unwind the same with the same end traveling foremost as when wound it may be accomplished bygunwinding the tape from the center outwardly without any intermediate rewinding step or th remom of the coil bodily from the container. This is especially advantageous in connection with tapes which are encoded or perforated with a e or telegram thereon and which arrives in a centrsl or exchange ofilce over a machine in one part of the building and is retransmitted over another machine located in another part of the building requiringthat the tape be transported bodily from the one to the other.
