Abstract
Abstract of the Disclosure The present system is comprised of an elongated member which has a finger like protrusion and a cam protrusion both of which are disposed close to one end thereof. The elongated member has an elongated slot at one end which fits over a stud and is further rotationally coupled to a crank so that the elongated member can pivot around said stud in a number of different positions in response to the crank being moved. The crank is rotationally coupled to a cam follower and the crank is further arranged to rotate about a stud. When a tape leader from a take up reel is to be joined to a tape leader from a supply reel, the elongated member is moved toward the tape leader from the take up reel and the finger like protrusion enters a first slot in the take up reel leader and moves that leader to an extended position whereat the cam protrusion cams a tab on the end of the take up reel leader away from the elongated member. The tab is formed to have a stem section. The supply reel leader which is extended has a locking slot therein which has a first section which fits over the tab. In response to said camming action, the elongated member is moved such that said cam protrusion cams said tab deeply into said locking slot and said tab becomes locked in a narrow section of said locking slot.
Description
3~"~ '31~
In tape handling devices it is necessary to have a reel which is "taking up", or winding the tape that is coming off the supply reel. Very often, in the prior art, the take up reel and the supply reel are not distinguishable because each acts -to either "take up" or "supply" depending on which way the tape is being run.
It is also true, in the prior art, that both reels are often located in the same housing, such as a cassette.
However there are some applications in the prior art where the supply reel is provided as an entity unto itself and -the tape thereon is pulled therefrom onto an "emp-ty" take up reel. A film on a motion picture projector is a typical example. Other uses of this kind are well known. In the prior art, with such arrangements, there has always been a certain amount of human factor involved.
For instance in a motion picture projector arrangement, the film is threaded along a group of sprocketed drivers and idlers. In some other arrangements, the tape is pulled from the supply reel and "grabbed" by a vacuum port on the take up reel. In another arrangement the tape is pulled from the supply reel and hand loaded onto a take up reel whereat there is a sheath. The sheath in response to movement of the take up reel, operates to squeeze the tape and hold it in position while the tape winds on itself.
The present system provides a means for a minimum of human intervention in making ready a system to pull tape from a supply reel onto a take up reel.
SU~ Y
The presen-t system lies in a mechanism for joining a first tape leader with a second tape leader wherein said first tape leader is formed to have a -tab at an end thereof and is - 3 - ~
further formed to have a positioningslot therein, and wherei.n ~ai~ second tape leader is formed to have a locking slot therein which locking slot is formed along a first section to be sufficiently wide to permit said tab to pass therethrough and formed at a second section to be sufficiently narrow to prevent said tab from passing therethrough, comprising in combination: an elongated member formed to have finger like protrusion, said finger like protrusion disposed so that when said elongated member is directed in a first movement said protrusion fits into said positioning slot and moves said tab into an extended position, said elongated member further formed to have a cam protrusion which is disposed such that in response to said first movement said tab is cammed thereby in a first direction; translational linkage means coupled to said elongated member and formed to move said elongated member in said first movement whereby, when said locking slot lies opposite said tab, said tab is cammed in said first direction through said locking slot to be ultimately locked in said second section thereof.
The leaders per se are the subject of my co-pending Canadian patent application, "Means for Pulling Tape From a Reel" serial number ~83,959.
According to another aspect oE the invention there is provided a mechanism for joining a first tape leader with a second tape leader wherein said first tape leader is formed to have a tab at an end thereof and is further formed to have a positioning slot therein, and wherein said second tape leader is formed to have a locki.ng slot therein which locking slot is formed along a first section to be sufficiently wide to permit said tab ~o pass therethrough and formed at a second section to be sufficiently narrow to prevent said tab from passing therethrough, comprising in combina-tion: an elongated member formed to have a finger like protrusion, said finger like protrusion disposed so that when said elongated member is directed in a first movement said protrusion fits into said positioning slot and moves said tab into an extended position, said elongated member further formed to have a cam protrusion which is disposed such that in response to said first rrlovement said tab is cammed thereby in a first direction;
crank means rotationally coupled to said elongated member and rotationally coupled to a first stud; cam follower means rotation-ally coupled to said crank means whereby when said cam follower is moved, it rotationally moves said crank around said first stud and thus said elongated mernber is moved in said first movement so -that when said locking slot lies opposite said tab, said tab is cammed in said first direction through said locking slot to be ultimately locked in said second section thereof.
According to a :Eurther aspect of the invention -there is provided a mechanlsm for joining a first tape leader with a second tape leader, said first tape leader having one end secured to a take up tape reel and a second end with a tab supported by a stem section that is narrower than said tab, said second tape leader having one end connected to tape on a supply tape reel rotatably positioned within a housing and a second end with a locking slot therein, wherein said locking slot comprises a first portion sized to permit said tab to pass therethrough and a second portion toward the second end of said second tape leader, said second portion sized to prevent said tab from passing therethrough while permitt-ing said stem section to pass therethrough, whereby, upon locking ~Yi -- 5 4~
sa.id firs-t and second tape leaders together, tape may be trans-ferred between said take up tape reel and said supply tape reel along a tape path, said mechanism comprising: first positioning means for positioning said first tape leader substantially within the tape path, and means for guiding said housing from an in-active position to an active position such that the movement of said housing to the active position causes said tab of said first tape leader to enter and extend through said first portion of said locking aperture so that rotation of the take up reel to pull said first tape leader draws said stem section into said second por-tion of said locking aperture to thereby lock said first ~nd second tape leaders together.
The objects and features of the presen-t invention will be better understood in view of the following description studied in conjunction with the drawings wherein:
Figure 1 depic-ts the elongated member holding the take up leader prior to locking it in the supply tape leader;
Figure 2 depicts the tab oE the take up leader when it is first inserted into the locking slot a-t the supply tape leader;
Figure 3 depicts the arrangement as the housing of the supply reel moves the cam follower;
Figure 4 depicts the arrangemen-t when the housing of the supply reel reaches its operating position; and Figures 5A, 5B and 5C depict the take up leader and supply tape leader in succeeding stages of being buckled.
Consider Figure 1. In Fiyure 1 there is shown an elonga-ted member 11. As can be seen in Figure 1, the lower end of the elongated member 11 it is formed into a finger like 'J j~, - 5a ~
;?~
protrusion 13 and a cam protrusion 15. Also as can be seen in Figure 1, the elongated member 11 is coupled to a crank 21 by a stud 19. The crank 21 is rotationally coupled by a stud 23 to a cam follower 17. The crank 21 is rotationall~ coupled to a s-tud 25. As will become apparent, hereinafter, the function of the linkage arrangement (i.e. the crank 21, the cam follower 17 and their rotational coupling design~ is to enable the elongated member to first pull the take up reel leader into an extended position for joining with ,, - 5b -the supply reel leader; secondl~ cam the tab of the take up leader into the locking slot of the supply tape leader; and thirdly retract the finger like protrusion frsm the positioning slot of the take up leader and simultaneously move the cam protrusion "out of the way" when the leaders have been joined to9ether. Other forms of mechanical linkage arrangement could be used to maneuver the elongated member so as to accomplish its purpose.
In Figure 1 the take up leader 27 is shown with the finger like protrusion 13 fitted through the positioning 510t 29. The positioning slot 29 can be seen in Figures 5 (A9 B and C) and is depicted in Figure 1 as a clear section of the leader as opposed to a solid line. Also in Figure 1 a top view of a portion of the housing 31 of the supply reel is shown. It should be understood that the housing 31 is three dimensional extending up from the drawing toward the viewer and that its lower edge 33 serves as a cam. ~he lower edge 33 moves the cam follower 17 as the housing 31 is moved to the left of the drawing to its ultimate operating position The housing 31 moves within two guide rails, not shown, and comes to rest against d bumper means when it is in the correct opclating position. The guide rails and the bumper enable the user to quickly insert the cartridge, (i.e. the housing 31 with the supply reel located therein) and to automatically join the two leaders.
As can be seen in Figure 1, the housing 31 has a channel 35 formed ~herein from whence the supply tape leader 37 extends. The supply tape leader 37 has a locking slot 39 which can be readily seen in Figure 5 (A, B and C) and which i5 shown as a clear area in Figure 1. It should be understood that (in a preferred embodiment) the leaders 27 and 37 are made of a polyester material with a thickness of .004 to .Ol~ mils.
Accordingly the leaders are relatively stiff to accommodate the automatic maneuvering of the tab into the locking slot. The tab which has been mentioned above is dep;cted in Figure 1 as tab 41. The shape of the tab 41 can be better appreciated in Figure 5. Whi1e in a preferred embodiment the tab 41 is shown to substantially resemble a mushroom, other shapes could be used.
It ~hould be further noted that the crank 21 is spring loaded by the spring 43 to move the linkage arrangement against the stop stud 45.
When the linkage is ~oved against the stop stud 45 the take up leader 27 is in the correct position to be inserted into the locking slot of the supply tape leader 37. While it is preferable to spring load the mechanism it will operate without spring loading provided the linkage is moved to properly locate the tab 41.
It should be noted that at the top end of the elongated member 11 there is formed an elongated aperture 47. The aperture 47 fits over the stud 49 and such an arrangement permits the elongated member 11 to move both rotationally and linearly, which translational movement is needed to enable the elongated member to cam the tab into the locking slot and at a later time move it "out of the way".
Consider Figure 2. In Figure 2 the housing 31 is shown in a pos;tion where its lower edge 33 is about to commence moving, or camming, the cam follower 17. In this initial camming position, the cam protrusion 15 has pushed the tab 41 substantially through the locking slot 39. It should be understood that depending upon the design of the leaders and the wishes of the user, the elongated member 11, the linkage arrangement and in particular the cam protrusion 15 can all be designed to move the tab 41 more or less completely through the locking slot 39.
In Figure 2 it ean be seen ~hat the lower edge 33 abuts the cam follower 17 at point 51.
As the housing 31 is moved to the left, wi~hin its guide rails, it pushes the cam follower 17 which "rolls", as shown by arrow 53, and pivots around the stud 23. In addition the crank 21 commence a slight ~ 3~d~
rotational movement (arrow 55~ about the stud 25. Tho foregoing movement of the linkage causes the cam protrusion 15 to cam or push, the tab 41 further into the locking slot as the locking slot is pushed toward the cam protrusion 15.
Consider Figure 3. In Figure 3 the housing 31 is shown moved considerably to the left. Under the conditions shown in Figure 3, the housing 31 has not yet gotten to the end of its travel, i.e. into its operating position. However in the intermediate position shown in Figure 3, the tab 41 is shown pushed well into the locking slot 39. As can be determined from Figure SA when the tab 41 is well into the slot, the stem 57 is located in the narrow section 59 so that as the take up leader 27 is moved away from (in a pulling direction) the supply tape leader 37, the stem 57 will pass through the narrow section 59 but the tab 41 ~ill be blocked. To say it another way, the overlap sections 61 and 63 will abut the outer limi~s 65 and 67 of the narrow section 59 and the leaders will become buckled. At this point in the buckling procedure the take up leader is pulled toward the bottom of the drawing to cause the stem 57 to pass through the narrow section 59 while the tab becomes blocked. The pulling can be effected by providing power to the take up reel or by manually winding the take up reel.
Consider Figure 4. In Figure 4 the housing 31 is shown having been moved considerably to the left to come into contact with bumper 69. In Figure 4 the housing 31 is shown in its operating position. As can be seen in Figure 4 the elongated member 11 has been moved away from the take up leader. The finger like protrusion 13 has slipped out of the positioning slot 29 and the cam protrusion 15 has moved out of the locking slot 39. As can be further seen in Figure 4 the tape leaders 27 and 37 are joined for operation, that is the pulling of the supply tape from the housing 31 and the taking up thereof by the take up reel.
Figures 5 (A, B, and C~ show the take up reel leader 27 bo,ng inserted in three steps into the supply tape leader 37. The prerequisites fsr the leaders 27 and 37 is that they be stiff enough to accommodate the operation described, that one section of the locking slot be wide enough to accept the tab and that another section be narrow enough to pass the stem but block the tab when the take up leader is pulled. These features and their relationship is apparent from Figures 5A, 5B and 5C.
It should be recognized that the joining of the leaders is quite automatic in response to the supply reel housing being inserted into its operating position as described above.
In tape handling devices it is necessary to have a reel which is "taking up", or winding the tape that is coming off the supply reel. Very often, in the prior art, the take up reel and the supply reel are not distinguishable because each acts -to either "take up" or "supply" depending on which way the tape is being run.
It is also true, in the prior art, that both reels are often located in the same housing, such as a cassette.
However there are some applications in the prior art where the supply reel is provided as an entity unto itself and -the tape thereon is pulled therefrom onto an "emp-ty" take up reel. A film on a motion picture projector is a typical example. Other uses of this kind are well known. In the prior art, with such arrangements, there has always been a certain amount of human factor involved.
For instance in a motion picture projector arrangement, the film is threaded along a group of sprocketed drivers and idlers. In some other arrangements, the tape is pulled from the supply reel and "grabbed" by a vacuum port on the take up reel. In another arrangement the tape is pulled from the supply reel and hand loaded onto a take up reel whereat there is a sheath. The sheath in response to movement of the take up reel, operates to squeeze the tape and hold it in position while the tape winds on itself.
The present system provides a means for a minimum of human intervention in making ready a system to pull tape from a supply reel onto a take up reel.

The objects and features of the presen-t invention will be better understood in view of the following description studied in conjunction with the drawings wherein:
Figure 1 depic-ts the elongated member holding the take up leader prior to locking it in the supply tape leader;
Figure 2 depicts the tab oE the take up leader when it is first inserted into the locking slot a-t the supply tape leader;

Consider Figure 1. In Fiyure 1 there is shown an elonga-ted member 11. As can be seen in Figure 1, the lower end of the elongated member 11 it is formed into a finger like 'J j~, - 5a ~

Other forms of mechanical linkage arrangement could be used to maneuver the elongated member so as to accomplish its purpose.
In Figure 1 the take up leader 27 is shown with the finger like protrusion 13 fitted through the positioning 510t 29. The positioning slot 29 can be seen in Figures 5 (A9 B and C) and is depicted in Figure 1 as a clear section of the leader as opposed to a solid line. Also in Figure 1 a top view of a portion of the housing 31 of the supply reel is shown. It should be understood that the housing 31 is three dimensional extending up from the drawing toward the viewer and that its lower edge 33 serves as a cam. ~he lower edge 33 moves the cam follower 17 as the housing 31 is moved to the left of the drawing to its ultimate operating position The housing 31 moves within two guide rails, not shown, and comes to rest against d bumper means when it is in the correct opclating position.

The supply tape leader 37 has a locking slot 39 which can be readily seen in Figure 5 (A, B and C) and which i5 shown as a clear area in Figure 1.

Accordingly the leaders are relatively stiff to accommodate the automatic maneuvering of the tab into the locking slot. The tab which has been mentioned above is dep;cted in Figure 1 as tab 41. The shape of the tab 41 can be better appreciated in Figure 5. Whi1e in a preferred embodiment the tab 41 is shown to substantially resemble a mushroom, other shapes could be used.
It ~hould be further noted that the crank 21 is spring loaded by the spring 43 to move the linkage arrangement against the stop stud 45.
When the linkage is ~oved against the stop stud 45 the take up leader 27 is in the correct position to be inserted into the locking slot of the supply tape leader 37. While it is preferable to spring load the mechanism it will operate without spring loading provided the linkage is moved to properly locate the tab 41.

The aperture 47 fits over the stud 49 and such an arrangement permits the elongated member 11 to move both rotationally and linearly, which translational movement is needed to enable the elongated member to cam the tab into the locking slot and at a later time move it "out of the way".

As can be seen in Figure 4 the elongated member 11 has been moved away from the take up leader. The finger like protrusion 13 has slipped out of the positioning slot 29 and the cam protrusion 15 has moved out of the locking slot 39. As can be further seen in Figure 4 the tape leaders 27 and 37 are joined for operation, that is the pulling of the supply tape from the housing 31 and the taking up thereof by the take up reel.
Figures 5 (A, B, and C~ show the take up reel leader 27 bo,ng inserted in three steps into the supply tape leader 37. The prerequisites fsr the leaders 27 and 37 is that they be stiff enough to accommodate the operation described, that one section of the locking slot be wide enough to accept the tab and that another section be narrow enough to pass the stem but block the tab when the take up leader is pulled. These features and their relationship is apparent from Figures 5A, 5B and 5C.
It should be recognized that the joining of the leaders is quite automatic in response to the supply reel housing being inserted into its operating position as described above.

A mechanism for joining a first tape leader with a second tape leader wherein said first tape leader is formed to have a tab at an end thereof and is further formed to have a positioning slot therein, and wherein said second tape leader is formed to have a locking slot therein which locking slot is formed along a first section to be sufficient-ly wide to permit said tab to pass therethrough and formed at a second section to be sufficiently narrow to prevent said tab from passing therethrough, comprising in combination: an elongated member formed to have a finger like protrusion, said finger like protrusion disposed so that when said elongated member is directed in a first movement said protrusion fits into said positioning slot and moves said tab into an extended position, said elongated member further formed to have a cam protrusion which is disposed such that in response to said first movement said tab is cammed thereby in a first direction; crank means rotationally coupled to said elongated member and rotationally coupled to a first stud; cam fol-lower means rotationally coupled to said crank means whereby when said cam follower is moved, it rotationally moves said crank around said first stud and thus said elongated member is moved in said first movement so that when said locking slot lies opposite said tab, said tab is cammed in said first direction through said locking slot to be ultimately locked in said second section thereof.
A mechanism for joining a first tape leader with a second tape leader wherein said first tape leader is formed to have a tab at an end thereof and is further formed to have a positioning slot therein, and wherein said second tape leader is formed to have a locking slot therein which locking slot is formed along a first section to be sufficient-ly wide to permit said tab to pass therethrough and formed at a second section to be sufficiently narrow to prevent said tab from passing therethrough, comprising in combination: an elongated member formed to have a finger like protrusion, said finger like protrusion disposed so that when said elongated member is directed in a first movement said protrusion fits into said positioning slot and moves said tab into an extended position, said elongated member further formed to have a cam protrusion which is disposed such that in response to said first movement said tab is cammed thereby in a first direction; crank means rotationally coupled to said elongated member and rotationally coupled to a first stud; cam fol-lower means rotationally coupled to said crank means whereby when said cam follower is moved, it rotationally moves said crank around said first stud and thus said elongated member is moved in said first movement so that when said locking slot lies opposite said tab, said tab is cammed in said first direction through said locking slot to be ultimately locked in said second section thereof.
7. A mechanism for joining a first tape leader with a second tape leader, said first tape leader having one end secured to a take up tape reel and a second end with a tab supported by a stem section that is narrower than said tab, said second tape leader having one end connected to tape on a supply tape reel rotatably positioned within a housing and a second end with a locking slot therein, wherein said locking slot comprises a first portion sized to permit said tab to pass therethrough and a second portion toward the second end of said second tape leader, said second portion sized to prevent said tab from passing therethrough while permitting said stem section to pass therethrough, whereby, upon locking said first and second tape leaders together, tape may be transferred between said take up tape reel and said supply tape reel along a tape path, said mechanism comprising: first positioning means for positioning said first tape leader substantially within the tape path, and means for guiding said housing from an inactive position to an active position such that the movement of said housing to the active position causes said tab of said first tape leader to enter and extend through said first portion of said locking aperture so that rotation of the take up reel to pull said first tape leader draws said stem section into said second portion of said locking aperture to thereby lock said first and second tape leaders together.
8. A mechanism according to claim 7 further comprising a second positioning means for positioning said second tape leader substantially within said tape path in an orientation adapted to promote the passage of said tab through said first portion of said locking aperture upon movement of said housing from the inactive to the active position.
9. A mechanism according to claim 8 wherein said second positioning means includes a channel within said housing and shoulders projecting from said second tape leader whereby said shoulders and said channel cooperate in orienting said second tape leader.
10. A mechanism according to claim 9 wherein said first positioning means includes supporting means for releasably sup-porting said first tape leader.
11. A mechanism according to claim 10 wherein said supporting means includes a projecting member adapted for pushing said tab of said first tape leader through said first portion of said locking aperture in said second tape leader.
12. A mechanism according to claim 11 wherein said supporting means releases the first tape leader after said tab of said first tape leader is pushed through said locking aperture.
13. A mechanism according to claim 12 wherein said supporting means includes a finger like protrusion that extends through an aperture in said first tape leader such that said first tape leader is supported thereby.
14. A mechanism according to claim 10 wherein said supporting means is an elongated member having a cam projection adapted for pushing said tab through said first portion of said locking aperture and a finger like protrusion that extends through a positioning aperture in said first tape leader such that said first tape leader can be positioned and supported on said elongated member by said finger like protrusion.
15. A mechanism according to claim 14 wherein said finger like protrusion exits from the positioning aperture in said first tape leader after said tab of said first tape leader extends through said first portion of said locking aperture in said second tape leader, whereby said first tape leader is released from said supporting means upon the rotation of the take up reel to pull said first tape leader.
