ROBERT TAE/IES COPELAND AND ALBERT EDWY CHATTERSON, OF TORONTO, ONTARIO, CANADA.
LOOSE-LEAF BINDER.
Application led April 1, 1908, Serial No. 424,510. Renewed December 8, 1909.
To all whom it may concern:
Be it known that we, ROBERT J AMES COPE- LAND and ALBERT EDWY CrnrrTERsoN, both of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented certain new and useful Improvements in LooseLeaf Binders, of which the following is the specification.
@ur invention relates to improvements in locks for loose leaf binders, and the object of the invention is to devise a simple, cheap and effective lock for loose leaf binders, which is not liable to get out of order and it consists essentially of a socket in the lower member of the binder, a round post turnably secured in the upper end of the binder and provided with a key hole at the top and having a ratchet-shaped tooth rack, a sleeve fitting over the post and provided with a slot, a pawl held in the slot, so as to engage with the rack, the parts being otherwise constructed and arranged in detail as hereinafter more particularly explained.
Figure 1, is a perspective view of a binder showing the cover mostly broken away and in section, exhibiting the position and general arrangement of our improved lock. Fig. 2, is an enlarged sectional detail of the lock and binder. Fig. 3, is a view of portion of a lock showing the pawl engaging with the rack on the post. Fig. il, is a view showing the post turned, so that the pawl is free from engagement with the rack. Fig. 5, is a detail of the sleeve in which the pawl tits. Fig. G, is a detail of the pawl.
ln the drawings like letters of reference indicate corresponding p'arts in each figure.
A is the upper member' and B the lower member of a loose leaf binder, the major portion of the cover being broken away and only the binder portion being disclosed in the drawing.
A is a depending back plate attached to the upper portion and B the back plate attached to the lower portion, one of which slides inside of the other.
C is a longitudinal plate secured underneath the upper member A and having attached thereto the sockets C and posts C2.
D is a longitudinal plate secured to the lower member' B of the binder and provided with the posts and sockets D and D2 which co-act with the sockets C and post C2 respectively.
E is the ordinary spiral spring located in Specification of Letters Patent.

the sockets and designed to force the top and bottom of the binder apart, such spiral spring being shown in Fig. l.
Thus far the construction is of the ordinary type used in binders of this class.
F is a central socket secured in the longitudinal plate D and provided with a supplemental sleeve F having a T-shaped recess F2, the depending portion of which eX- tends through the sleeve F.
G is a post having a ratchet-shaped rack G, the inclined portion of each tooth being lowermost as indicated. The post G has an enlargement G2 at the upper end, which is provided with a key socket G3 and a anged top G4.
H is a pin, largement G2 and which serves with the flange GL1 to hold the post securely in the upper member of the binder.
I is astop pin, which depends from the plate C in the path of the pin H as it turns. J is a T-shaped pawl, the upper horizontal portion of which fits in the upper portion of the recess F2 and the lower end of which has an inward turn J.
K is the key, which is provided with the usual web.
L is the escutcheon plate secured to the top of the member A opposite the post G and provided with the usual slot for a key. The socket G3 is provided with a recess and shoulders G5 against which the web of the key abuts when it is turned, so as to turn the post G.
Having now described the principal parts involved in our invention we shall briefly describe its operation and utility. By inserting the key K into the top of the post G hereinbefore described and turning the key the post may be turned around from the position shown in Figs. 2 and 3 into the position shown in Fig. a, so that the pawl J passes out from the ratchet teeth when the two members of the binder will spring apart. In this position the web of the key will have passed from underneath its receiving slot and thereby the key will be held within the escutcheon plate L. When it is desired to contract the binder again the key may be given a half turn in the reverse direction, so as to bring the rack of the post G into engagement with the pawl again or it may be removed before the reverse operation takes place as it is not necessary to have the key which extends through the en` in for the purpose of locking the binder. The key is actually required for unlocking only. By pressing down on the member A the teeth of the rack post Gr Will pass the pawl in its descent and such pawl will lock each tooth as it descends, thereby holding the two members of the binder together. It is also pointed out that the pawl J when. once placed in position is permanently secured in place and consequently there is no liability of the co-acting parts failing to operate. lVhat we claim as our invention is:
l. ln a loose leaf binder, the combination with the upper member and lower member and connections, of a lock comprising a socket secured to the lower member, a supplemental socket located therein provided with a T-shaped recess, a post turnably secured in the upper member and provided with ratchet teeth, a T-shaped pawl held in a recess in the supplemental socket and provided with a bent end, and means for turning` the post, so as to release the pawl from the ratchet as and for the purpose specified.
2. In a loose leaf binder, the combination with the upper member and lower member and connections, of a lock comprising` a socket secured to the lower member, of a T- shaped recess Jformed therein, a post turnably secured in the upper member and provided with ratchet teeth and a `shaped pawl held in the recess in the supplemental socket and provided with a bent end, means for turning` the post, and means for holding the pawl within the recess, as and for the purpose specified.
