- the push rods are mounted parallel to one another and extend transversely of the binder support bar.
- the push rods are slidable axially in circular apertures 63 formed in the front and rear cross bars 42 and 44, respectively.
- the front ends of the push rods 62 are reduced in diameter and extend through complementary circular apertures 65 in an angle member 66, hereinafter to be referred to as the hook-carrying bar.
- the front ends of the push rods 62 are threaded and receive nuts 68 which abut the front face of the hook-carrying bar and secure the tie rods to the latter bar.
- a shoulder formed by the reduced end portion of each push rod abuts the rear face of the hook-carrying bar 66 so that the forward movement of each tie rod 62 is transmitted to the bar 66.
- the hook-carrying bar 66 includes a rearwardly ex tending shelf 72 at the top thereof which overlies the front half of the binder support bar 45.
- the bar 45 is cut away at 73 to make room for the shelf, the top of which is spaced slightly above the bar 45.
- a series of transverse grooves 74 are formed in the top of the shelf 72 and are spaced from each other the same distance as the spacing of the binder teeth.
- the rear end of the grooves 74 extend all the way to the rear face of the shelf 72 but the front ends thereof terminate short of the front edge of the shelf.
- Vertical bores 76 formed in the shelf communicate with the front ends of the grooves 74.
- Nestled in each of the grooves 74 and the bores 76 is a hook member 78 which is to engage the teeth of the binder.
- Each of the hooks 78 includes a straight horizontal intermediate shank portion 80, a depending vertical anchoring front end 82 and a horizontal extending binder teeth engaging rear end 84 which is at right angles to the intermediate shank portion 80.
- the hook ends 82 and 84 are thus located in different planes and one of them is at right angles to a line which is parallel to the other.
- the rear hook ends 84 are aligned along a horizontal line which is parallel to the row of fingers 58. Both of these hook ends are of the same length and they may be reversed in position so that the ends 82 become the binder teeth engaging ends and the ends 84 become the anchoring ends.
- the shanks 80 of the hooks are snugly nestled respectively in the grooves 74 and the front vertical ends 82 are snugly received in the bores 76.
- a number of screws 85 are threaded into the shelf 72 and the heads thereof overlie the shanks of the hooks to retain them securely in place within the grooves 74 and the bores 76.
- the lengths of the hook ends 82 and 84 are equal to the widths of the fingers 58.
- the hook ends 84 are located directly opposite the fingers and the finger indentations 59. If desired, the shanks of the hooks may be lengthened so that the hook ends 84 extend into the indentations 59.
- the sides of the hook ends 84 are flush with the sides of the slots 56 so that the binder backbone 8b may be placed against the fingers 58 with the binder teeth freely extending into the slots 56.
- the support bar 45 is moved to its farthest right position against the force of the tension spring 51, the binder teeth are brought into encircling relationship with the hook ends 84. In this position the hooks are located between the 4 fingers 58. Then, any forward movement of the hooks will uncurl the teeth of the binder.
- This as sembly includes a horizontally extending rotatable shaft 36 which is journalled in the end plates 10 and 12 of the frame.
- a link member 88 is secured to the shaft 86 by means of a collar 90.
- the end of the link member 88 is connected by a depending rod 89 to a suitable foot operated member (not shown).
- the link member 88 is biased in its upper position by means of a tension spring 90 which is anchored at one end to the forward tie rod 14 and at the other end to an arm 91 which is secured to the shaft 86 by a collar 93.
- the downward movement of the foot operated rod 89 is opposed by the tension spring, and the device is therefore normally urged into the position shown in Fig. 3.
- the rotary movement of the shaft 86 is converted to reciprocatory motion of the push rods 62 by means of a linkage assembly including the axially spaced, bifurcated link members 96 which are secured to the shaft 86 and include front and rear legs 96' and 96 which straddle a horizontal cross bar 97.
- the cross bar is secured at its ends to the push rods 62 by means of a pair of connecting blocks 98.
- the foot operated bar 89 In the normal position of the device shown in Fig. 3, the foot operated bar 89 is in its upper position and the front of the cross bar 97 is engaged by the front legs 96' of the bifurcations 96, to maintain the push rods in their rearward position.
- the hook-carrying bar 66 is then in its rearwardmost position, with the transverse ends 84 of the hooks located adjacent to the front face of the fingers 58.
- the pedal operated bar 89 When the pedal operated bar 89 is pulled downward, the link assembly is moved into the position shown in Fig. 5. This rotates the shaft 86 counter-clockwise and moves the rear legs 96" of the bifurcations 96 forward against the cross bar 97 to move the push rods 62 forward.
- the hook-carrying bar 66 is thus moved laterally forward of the binder support bar 45, carrying the books with it away from the bar 45.
- the forward movement of the hook-carrying bar 66 is limited by the abutment of a pair of lock nuts 100, carried at the end of one of the push rods, with the rear face of the rear cross bar 44 of the frame.
- the position of the lock nuts 100 on the push rod 60 may be varied to limit the amount of forward movement of the hook-carrying part 66 to the desired amount, depending on the size of the binder being uncurled.
- the locking means comprises a lever 102 which is pivoted to the lefthand end plate 10 intermediate its ends by a pivot pin 103.
- the forward end of the lever 102 carries an upstanding tooth 105 which is urged toward the bottom of the binder supporting bar 45 by a spring 106.
- a slot 108 is formed in the bottom of the binder support bar and it is so positioned that it will overlie the top of the tooth 105 only when the binder support bar is positioned in its farthest right position, where the projections 58 are located between the hook ends 84.
- a stop pin 112 carried by a collar 114 which is secured to the left hand end of the shaft 86, normally abuts the end of the lever 102 and prevents the spring 106 from drawing the tooth into the slot 108.
- the stop pin 112 is moved in a counter-clockwise direction away from the lever 102, thus enabling the tooth 105 to enter the slot 108 under the force of the spring 106.
- the stop pin 112 pushes the rear end of the lever 102 upward removing the tooth 105 from the slot 108.
- the binder support bar 45 then moves to the left under the control of the spring 51.
- a binder 5 Supported behind the binder support rod 45 is a binder 5.
- receiving tray 9. The tray includes a horizontal panel 116 which is secured to the top of the end plates and 12.
- the panel 116 overlies the entire frame structure of the device. and its forward end is located adjacent to the top of the binder support bar 45.
- the rear end of the panel 116 terminates in an upstanding retaining wall 118.
- Unused binders are supported on the tray.
- the relationship of the tray to the-bar 45 enables an operator to grasp a binder resting on the'tray and to position it on the binder support member 45in a minimum of time and with a minimum of effort.
- the operation of the device is as follows: A tubular binder is placed on the binder support bar 45 so that the binder teeth straddle the fingers 58 and the backbone engages the'rear of the-fingers 58. The two outermost teethof the binder straddle the Wider outer projection 58 with the teeth facing forwardly of the device. The bottoms of the curled binder teeth extend into the slots 56 and they rest on the-bottoms thereof. The binder support bar 45 is then in its far left position and the hooks are in front of the fingers 58 so that they do not interfere with the placement of the binder on the support bar 45. Next the binder support bar 45 is moved manually to the right, bringing thebinder teeth in encircling relationship with the hook ends84.
- the foot operated rod 89 is then pulled downward against the force of the spring 90, whereupon the movement of the lock pin 112 allows the tooth 105 to enter the slot108, thereby locking the binder support bar 45 into a position Where the binder teeth encircle the hooks.
- the hook-carrying bar 66 is moved forward and the hook ends 84 engage and uncurl the teeth of the binder, as shown in Fig. 5.
- the right end of the binder backbone 8b is prevented from bending appreciably forward and laterally inward by the fingers 58 which fits snugly between the last two binder teeth near. the backbone so as to brace the backbone near the. base. of the binder teeth where the bending would take place.
- This bracing is not needed at the left end of the binder where the hooks are facing outward of the binder, since any appreciable flexing of the binders is prevented by the left hand hook 78. Note that the right hand hook 78 faces inward of the binder.
- binders to be used with the device of the invention are one-half or less than one-half of the distance between the outermost uncurling hooks 78, then several binders may be uncurled simultaneously. In such case, it is preferred to substitute a wide finger like 58 for one of the narrow fingers 58 at the location of the space between the two last teeth at the right end of the binder to prevent the undesirable flexing of the backbone referred to above.
- the force of the tension spring 51 could pull the binder teeth out of engagement with the hooks unless the bar were maintained in that position by hand.
- the locking means just described, enables both hands of the operator to be utilized in placing the slotted sheets over the upwardly facing ends of the uncurled binder teeth.
- the pedal operated rod 89 is released, and it returns to the position shown in Fig. 3.
- the binder teeth-engaging hooks 84 are then adjacent the fingers 58 and the binder teeth are in their normal curled position. In this position, the binder support bar 45 has been returned to its left hand position by the spring 51 since the tooth 105 has then been disengaged from the slot 108.
- the hooks 78 are preferably initially located a small distance above the bottom of the uncurled binder as viewed in Fig. 3.
- the position of the binder relative to the hooks is determined by the depth of the finger receiving slots 56.
- the depth of the slots 56 decreases toward the rear finger-receiving side of the binder support bar to accommodate binders of different diameters.
- the smaller binders will be supported in the proper position with respect to the hooks 78 while resting on the shallow may be made of the preferred embodiment of the inven-.

The front ends of the push rods 62 are reduced in diameter and extend through complementary circular apertures 65 in an angle member 66, hereinafter to be referred to as the hook-carrying bar. The front ends of the push rods 62 are threaded and receive nuts 68 which abut the front face of the hook-carrying bar and secure the tie rods to the latter bar. A shoulder formed by the reduced end portion of each push rod abuts the rear face of the hook-carrying bar 66 so that the forward movement of each tie rod 62 is transmitted to the bar 66.
The hook-carrying bar 66 includes a rearwardly ex tending shelf 72 at the top thereof which overlies the front half of the binder support bar 45. The bar 45 is cut away at 73 to make room for the shelf, the top of which is spaced slightly above the bar 45. A series of transverse grooves 74 (see Fig. 9) are formed in the top of the shelf 72 and are spaced from each other the same distance as the spacing of the binder teeth. The rear end of the grooves 74 extend all the way to the rear face of the shelf 72 but the front ends thereof terminate short of the front edge of the shelf. Vertical bores 76 formed in the shelf communicate with the front ends of the grooves 74. Nestled in each of the grooves 74 and the bores 76 is a hook member 78 which is to engage the teeth of the binder.
Each of the hooks 78 includes a straight horizontal intermediate shank portion 80, a depending vertical anchoring front end 82 and a horizontal extending binder teeth engaging rear end 84 which is at right angles to the intermediate shank portion 80. The hook ends 82 and 84 are thus located in different planes and one of them is at right angles to a line which is parallel to the other. The rear hook ends 84 are aligned along a horizontal line which is parallel to the row of fingers 58. Both of these hook ends are of the same length and they may be reversed in position so that the ends 82 become the binder teeth engaging ends and the ends 84 become the anchoring ends. The shanks 80 of the hooks are snugly nestled respectively in the grooves 74 and the front vertical ends 82 are snugly received in the bores 76. A number of screws 85 are threaded into the shelf 72 and the heads thereof overlie the shanks of the hooks to retain them securely in place within the grooves 74 and the bores 76.
The lengths of the hook ends 82 and 84 are equal to the widths of the fingers 58. When the binder support bar 45 is in its farthest left position, the hook ends 84 are located directly opposite the fingers and the finger indentations 59. If desired, the shanks of the hooks may be lengthened so that the hook ends 84 extend into the indentations 59. The sides of the hook ends 84 are flush with the sides of the slots 56 so that the binder backbone 8b may be placed against the fingers 58 with the binder teeth freely extending into the slots 56. When the support bar 45 is moved to its farthest right position against the force of the tension spring 51, the binder teeth are brought into encircling relationship with the hook ends 84. In this position the hooks are located between the 4 fingers 58. Then, any forward movement of the hooks will uncurl the teeth of the binder.
The means for imparting lateral movement to the hook-carrying bar 66 will now be described. This as sembly includes a horizontally extending rotatable shaft 36 which is journalled in the end plates 10 and 12 of the frame. A link member 88 is secured to the shaft 86 by means of a collar 90. The end of the link member 88 is connected by a depending rod 89 to a suitable foot operated member (not shown).
The link member 88 is biased in its upper position by means of a tension spring 90 which is anchored at one end to the forward tie rod 14 and at the other end to an arm 91 which is secured to the shaft 86 by a collar 93. The downward movement of the foot operated rod 89 is opposed by the tension spring, and the device is therefore normally urged into the position shown in Fig. 3. The rotary movement of the shaft 86 is converted to reciprocatory motion of the push rods 62 by means of a linkage assembly including the axially spaced, bifurcated link members 96 which are secured to the shaft 86 and include front and rear legs 96' and 96 which straddle a horizontal cross bar 97. The cross bar is secured at its ends to the push rods 62 by means of a pair of connecting blocks 98.
In the normal position of the device shown in Fig. 3, the foot operated bar 89 is in its upper position and the front of the cross bar 97 is engaged by the front legs 96' of the bifurcations 96, to maintain the push rods in their rearward position. The hook-carrying bar 66 is then in its rearwardmost position, with the transverse ends 84 of the hooks located adjacent to the front face of the fingers 58. When the pedal operated bar 89 is pulled downward, the link assembly is moved into the position shown in Fig. 5. This rotates the shaft 86 counter-clockwise and moves the rear legs 96" of the bifurcations 96 forward against the cross bar 97 to move the push rods 62 forward. The hook-carrying bar 66 is thus moved laterally forward of the binder support bar 45, carrying the books with it away from the bar 45. The forward movement of the hook-carrying bar 66 is limited by the abutment of a pair of lock nuts 100, carried at the end of one of the push rods, with the rear face of the rear cross bar 44 of the frame. The position of the lock nuts 100 on the push rod 60 may be varied to limit the amount of forward movement of the hook-carrying part 66 to the desired amount, depending on the size of the binder being uncurled.
Means is provided for locking the binder support bar 45 in its farthest right position, where the hook ends 84 are encircled by the teeth of the binder. The locking means comprises a lever 102 which is pivoted to the lefthand end plate 10 intermediate its ends by a pivot pin 103. The forward end of the lever 102 carries an upstanding tooth 105 which is urged toward the bottom of the binder supporting bar 45 by a spring 106. A slot 108 is formed in the bottom of the binder support bar and it is so positioned that it will overlie the top of the tooth 105 only when the binder support bar is positioned in its farthest right position, where the projections 58 are located between the hook ends 84. In this position, a stop pin 112, carried by a collar 114 which is secured to the left hand end of the shaft 86, normally abuts the end of the lever 102 and prevents the spring 106 from drawing the tooth into the slot 108. When, however, the rod 89 is pulled downward, the stop pin 112 is moved in a counter-clockwise direction away from the lever 102, thus enabling the tooth 105 to enter the slot 108 under the force of the spring 106. When the pedal operated rod 89 returns to its upper position, the stop pin 112 pushes the rear end of the lever 102 upward removing the tooth 105 from the slot 108. The binder support bar 45 then moves to the left under the control of the spring 51.
Supported behind the binder support rod 45 is a binder 5. receiving tray 9. The tray includes a horizontal panel 116 which is secured to the top of the end plates and 12. The panel 116 overlies the entire frame structure of the device. and its forward end is located adjacent to the top of the binder support bar 45. The rear end of the panel 116 terminates in an upstanding retaining wall 118. Unused binders are supported on the tray. The relationship of the tray to the-bar 45 enables an operator to grasp a binder resting on the'tray and to position it on the binder support member 45in a minimum of time and with a minimum of effort.
The operation of the device is as follows: A tubular binder is placed on the binder support bar 45 so that the binder teeth straddle the fingers 58 and the backbone engages the'rear of the-fingers 58. The two outermost teethof the binder straddle the Wider outer projection 58 with the teeth facing forwardly of the device. The bottoms of the curled binder teeth extend into the slots 56 and they rest on the-bottoms thereof. The binder support bar 45 is then in its far left position and the hooks are in front of the fingers 58 so that they do not interfere with the placement of the binder on the support bar 45. Next the binder support bar 45 is moved manually to the right, bringing thebinder teeth in encircling relationship with the hook ends84. The foot operated rod 89 is then pulled downward against the force of the spring 90, whereupon the movement of the lock pin 112 allows the tooth 105 to enter the slot108, thereby locking the binder support bar 45 into a position Where the binder teeth encircle the hooks. The hook-carrying bar 66 is moved forward and the hook ends 84 engage and uncurl the teeth of the binder, as shown in Fig. 5. The right end of the binder backbone 8b is prevented from bending appreciably forward and laterally inward by the fingers 58 which fits snugly between the last two binder teeth near. the backbone so as to brace the backbone near the. base. of the binder teeth where the bending would take place. This bracing is not needed at the left end of the binder where the hooks are facing outward of the binder, since any appreciable flexing of the binders is prevented by the left hand hook 78. Note that the right hand hook 78 faces inward of the binder.
Where the binders to be used with the device of the invention are one-half or less than one-half of the distance between the outermost uncurling hooks 78, then several binders may be uncurled simultaneously. In such case, it is preferred to substitute a wide finger like 58 for one of the narrow fingers 58 at the location of the space between the two last teeth at the right end of the binder to prevent the undesirable flexing of the backbone referred to above.
If the binder support bar 45 was not locked into its right hand position, the force of the tension spring 51 could pull the binder teeth out of engagement with the hooks unless the bar were maintained in that position by hand. The locking means, just described, enables both hands of the operator to be utilized in placing the slotted sheets over the upwardly facing ends of the uncurled binder teeth. Following the insertion of the sheets over the binder teeth, the pedal operated rod 89 is released, and it returns to the position shown in Fig. 3. The binder teeth-engaging hooks 84 are then adjacent the fingers 58 and the binder teeth are in their normal curled position. In this position, the binder support bar 45 has been returned to its left hand position by the spring 51 since the tooth 105 has then been disengaged from the slot 108.
The hooks 78 are preferably initially located a small distance above the bottom of the uncurled binder as viewed in Fig. 3. The position of the binder relative to the hooks is determined by the depth of the finger receiving slots 56. The depth of the slots 56 decreases toward the rear finger-receiving side of the binder support bar to accommodate binders of different diameters. The smaller binders will be supported in the proper position with respect to the hooks 78 while resting on the shallow may be made of the preferred embodiment of the inven-.
tion above described without deviating from the broader aspects thereof.
