LOGSE-LEAF HOLDER.
Application fired Juiy 3,
This invention relates to loose-leaf holders, particularly adapted to releasably clamp a sheet or a plurality of sheets between the back and` cover thereof without the use of empaling members such as rings, posts, thongs or the like.
The invention is especially directed to what is known in the art as a sheet holder its primary object `the provision of a new and novel means for releasably retaining any number of sheets inthe holder through the use of a resilient member which is also adapted to retain the elements of the binder in'their assembled relation.
A further object of the present invention is to provide a novel means of forming the top and bottom elements of a loose-leaf holder whereby a special pivot pin may be interposed'to perform a function not heretofore known.
An even further object of this invention is the contemplation of a leaf-clamping member which is adapted to hingedly support a cover as well as to perform the function of a clamping memberto hold the leaves in place. i 1
Many minor objects will appear during thefcourse of the detailed specification referring to the accompanying drawing in which similar reference numerals designate like parts throughoutthe several views. in the drawing:
Figure 1 is a perspective view of' a looseleaf holder made in accordance with this invention.
Fig. 2 is an enlarged detailed section taken onv line II--II of Fig. y
Fig. 3 is `an end view of the hinged .portion ofthe holder showing the same in the completely opened position and, in the dotted lines, in a position ready to receiveA additional sheets.
F ig. l is a broken crosssection of the resilient retaining member taken on line IV-IV of Fig. 2, and,
Fig. 5 is a perspective view of the split tube retaining` member showing it removed from the holder.
rllhc holder made in accordance with this invention ispreferably constructed of sheet metal such as aluminum, and musthave a back and cover 6 and 7 respectively of a size to suit the particular size of sheet 8 to be used. These members 6 and 7 lmay be 1925. serial No. 41,378. p
ance.
,Back 6 is formed to provide an arcuate channel portion 10 at` its one end which is disposed on a plane above thatof the major portion ofthe baclfand which extends Vthe entire width thereof to receive a 115.` This pin 11 is preferably made of wood and treated to cause function as a smooth sliding' surface` for arcuate channel portion 12 of yleaf-,clamping member 13. As shown in Figs. 2 and 3, pin 11 is interposed between arcuate channel portion 1Q and 12 and is notdirectly connectec thereto 4in any way. K Furthernfiore, the' circumference of `pin 11 is greater than the combined distance across the two `arcuate channels and neither one nor both `portioifis 10 and `12 are large enough to pass completely around the pin 11. i
' To Yretain these members 6, 11 vand 13 in the assembledrelation, as well as to exert a leaf-holding pressure, a splittube resilient member 14 may. oe used which engages the convex surface of arcuate channel portionsA at points near where theyjoin bach 6 and leaf-clamping member 13. This member 13 at the edge opposite the arcuate channel por tion 12 is curled upwardly and baclzjupon itself 'to form a plurality of pintle barrels 15, spaced vapart by notches'l into which similarly are adapted to be disposed to receive .pintle 18 which passes through all barrels '15 and 17 to form a hinge as clearly shownv in Fig. 1. This hinge ypermits of p when desired without dislodgingI sheets 8. The pressure exerted by member 1e upon leaf clamping 'member 13, normally holds it in the closed position as shown i-n Fig. Qand against vany sheets? that might be lying upon bach Y bach 6 should lbe hinged back in the position shown in dotted lines of Fig. 3, and an upward leverage gained by causing the same to engage shoulder 19.V Thus, apressure in the direction of the arrow (Fig. 3) will cause the forward or hinge end of member 13 to rise. To completely open the holder, the same pressure is `carried back until top 7 and member 13 assume the position shown in full lines of Fig. 3. During'these operations, arcuate channel portion 12 of member `pivot .pin
constructed` barrels 17 of cover Tf raising `cover To open orraise member 13,
the same to properly l soy 13 is riding over the periphery of pivot pin 11 and member 14 is exerting asqueezing or inward pressure. Vhen ends 20 and 21 of upper and lower arcuate channel portions respectively meet, tlie opening action is stopped.
rllhis particular construction has been found to be of value in connection with many forms of binders, and it is desired to be limited in its use only by the scopeV of the app ended claims.
What I claimis: i
1. A loose-leaf holder comprising a back, leaf-clamping means supported by said back, a pivot pin interposed between said back and said leaf-clamping means andresilient means for maintaining said back and leafclainping means in direct sliding engagement with said pivot pin, the ends of said back and leaf-clainping means adjacent said pivot pin adapted to abut and limitmovement therearound.
2. A'loosedeaf holder compri-sing a back having an arcuate channel poition adjacent its one end and extending the entire width thereof, a pivot pin co-eXtensive withA said portion and seated therein, a 'leaf-clamping member having an arcuate channel portion adjacent one of its 'sides also adapted to directly engage said pivot pin, a cover hingedly connected to the other side of said leaf- Vclamping member and resilient means engaging the arcuate channel portion of said backV and clamping member along their entire length, each of said arcuate channels being rebent whereby an edge of the channel of said leaf-clamping member abuts an edge of the channel of said back when the holder is in either the open or closed position.
3. A loose-leaf holder comprising a back having an arcuate channel portion adjacent its one end, apivot pin seated therein, a leafclainping member having an arcuate channel portion adjacent one of its sides also adapted to directly engage said pivot pin, a cover hingedly connected to the other side of said leaf-clamping member and resilientmeans for retaining the arcuate channel portions of saidback and clamping member in sliding engagement with said pivot pin and the clamping member in either the open or closed position, said arcuate channels of the back and leaf-clamping member having their rearwardly facing edges spaced apart when said holder is in the leaf holding position, and forced together in abutting relation when said holder is in the extreme open position. v
el. In a loose-leaf holder of the character described, a back and a leaf-engaging member each having an arcuate channel formed therein, a pivot pin engaged by each of said arcuate channels, and means for retaining said channels in sliding engagement with said pin, said channels` extending but a part way around said pin, concentric therewith and bearing directly upon Lthe periphery thereof and having their edges in abutting relation when said holder is in the open position.
5. A loose-leaf holder comprising a back, a leaf-clamping means supported by said back, a cover hingedly cairi-ed by the clamping means, a resilient split tubular member holding said back and leaf clamping means in assembled relation and a shoulder formed across the leaf clamping means intermediate its sides,rsaid shoulder forming a bearing for the holding member and a stop for the cover whereby its opening action is terminated before reaching a position to engage said tubular member.
6. In a loose-leaf holder of the kind described, a back and a leaf clamping member each having an arcuate channel formed along one edge thereof, a pivot pin engaging both channels having a circumference greater than the combined distance across both of said arcuate channels and resilient means for keeping said arcuate channels in engagement with the periphery of said pin.
7. In a loose-leaf holder of the kind described, a back and a leaf clamping member each having an arcuate channel formed along oneedge thereof, a pin disposed between tlie channels and engaging the concave faces of the same, the combined distance across both channels being insufficient to reach around said pin and resilient means for maintaining the channels in sliding engagement with the pin, the adjacent edges of said channels abutting to limit. their movement around said pin. y
In testimony whereof I hereunto afx my signature this th day of June, 1925.
