,V Application filed July 8, 1907. Serial No. 382,791.

Patented .Tune 23, 1908.

To all' 'whom tt 'may concern:

Be it known that I, EDMoND FOURNIER, a subject of the King of Great Britain, residing at St.` Hyacinthe, county of St.. Hyacinthe,

in the Province of Quebec, Canada, have invented certain new and useful Improvements'in Loose-Leaf Binders and I do hereby declare that the followingk is a full, clear, and exact description of the invention, such as will enable others skilledin the art to f:which it appertains to make and use the same.

My invention relates to loose-leaf binders of theV general type comprising two covers adapted tocontain between thema plurality of record sheets, papers or the like, means for moving these covers bodily toward or from each other in order to securely clam-p the papers held therebetween regardless of '20 .theirenumber and devices for guiding the covers in their movements.

The present invention is designed to construct a binder of the general ty e above in which all tendency toward bin 'ng of the guiding parts is com letely overcome and to produce an article of this class in which the parts may be locked in their ad'usted positions and to securely guard the ook against persons who may wish to tamper with the same to gain access to papers in the binder.

Broadly speaking my invention comprises in combination with the covers common to devices of this class and guide rods and their coperating guide tubes connected 'to the late and connections between the back pllate and covers for guiding the covers as they are moved and a guard plate adapted to be moved over the key-hole through which the key is inserted to operate the rods whereby the covers are moved in one or the other direction.

As heretofore constructed binders of this general type have aHorded no substantial protection against persons wrongfully open- This was due to the fact that the slot or key-hole in the end of the o erating shaft was easily accessible and any key or piece of metal inserted therein would operate the actuating rod and so release the covers.

One of the prime objects of the present invention is to completely overcome this serious objection.

Another object is to prevent binding between the guide rods and their tubes.

In order to more clearly understand the construction and operation ofthe device ref-- erence should be had to the accompanying drawings forming part of this present application in which similar reference characters `designate like parts in' ally of the several views.`

Figure 1 is a front plan. view of the deviceA showing the back plate in elevation. Fig. 2y is a plan view ofthe end' plate or cap con-taining the guard plate and its actuatingmeans'. Fig. 3 is a longitudinal section through Fig. 2 looking from the opposite side tov that shown in Fig. 2 land showing the guard plate .in inoperative position. Fig. 4 is. a view similar to 3 with the guard platev in o Aerative position. Fig. 5 is a section on ne l 5 5.- of Fig. 2. Fig. l6 is a perspective in detailV showing the connecting pin in platey 1. Flg. 7 is a perspective of the'end or cap platek pposite. to the one:A containing the guard o p ate mechanism.

Referring to the drawings in detail, 1I repi resents. suitable covers of a form common to all devices ot this. genera-l' ty e.. Connected to the covers l any suitable manner are bars 2 or equivalent structures of any well known form carrying the usual guide rods or` pins 3 and their respective coperating guide tubes 4.

In order to prevent twisting lof the covers` and consequent binding between the members 3 and 4 I have provided a back late 5 provided with a fastening pin or stu 25 by which it is held to one end of the binder back. This plate as clearly shown in Fig. 1 is placed between the rod and tube connections and the back of the binder, the pin 25 engaging a suitable recess in the binder back.

In order that plate 5 may act las a guide I have provided t e same wlth suitable guide slots 6 ada ted to receive ins 7 attached to the lower a s or inturne edges of the covers 1 all as cllearly shown in Fig. 1. It follows that as the covers are moved in either direction, the late 5being stationary pins 7 will ride in s ots 6 and the covers will be maintained in perfect perpendicularity and vconsequent bindin between the' guide rods and guide tubes w be obviated.

To opposite ends of the back of the binder are attached respectively end caps 8 and 9 respectively provided with recessed Han es 21 adapted to receive and hold a suita le binding 22, see Fig. 7.

The end cap 9 has slidably mounted therein a guard plate 10 provided with an opening 13 adapted to register with a similar opening 14 through the outer face of the cap 9 through which latter o ening a key or other device may be asse to o erate the well known form of ey operate actuating rod whereby the covers are moved. Guide plate 10 has attached thereto a pin 11 which projects through a slot 12 in the end cap 9 and is provided with a suitable head by which it may be grasped and moved toward the right, Fig. 2, to thereby register openings 13 and 14 and allow insertion of a key for operating the actuating rod.

The plate 9 is held in its inoperative position with the o enings 13 and 14- in register as above by a og 15 pivoted at 16 adjacent said plate and provided with a notched arm lying in the path of movement of the plate. This dog is normally held elevated by the spring 18 as clearly shown in Figs. 3 and 4. The notched arm of dog 415 engages stud 17 on plate 10 and so holds the plate inoperative when it has been moved to this position by lthe pin 11.

In order to free the guard plate and allow it to be moved into operative position a key is` inserted in the opening 19 and the dog 15 turned to disengage its notched arm from stud 17, the knob on the end of in 11 is then grasped and the plate 10 move to operative position as shown in Figs. 2 and 4 and so eld by the arm of dog 15 which has now been forced upward into engagement with the shoulder 23 of plate 10, see Fig. 4.

Having now fully described the construction and operation of my device, what I claim and desire to secure by Letters Patent is:-

1. In a loose leaf binder, a key o erated actuating rod, a sliding guard plate ying in the path of insertion of a key for operating said actuating rod, means for slidlng said guard plate, a stud on said guard plate7 and a shoulder on said guard plate and a s ringactuated pawl provided with a notche arm, the notch of which is adapted to receive the aforesaid stud to hold the guard plate in inoperative position, whereas the end of the arm of said pawl is'adapted to engage the guard late beneath the shoulder thereon and to old it in operative position.

2. In a loose leaf binder, a key o erated actuating rod, a sliding guard plate ying in the path of insertion of a key for operating said actuating rod, means for sliding said guard plate, a stud on said guard plate, and a shoulder on said guard plate, a spring-actuated pawl provided with a notched arm, the notch of which is ada ted to receive the aforesaid stud to hold t e guard plate in inoperative position, whereas the end of the arm of said pawl is adapted to engage the guard plate beneath the shoulder thereon and to hold it in operative position, and a second arm on said lpawl adapted to be engaged by a key by whic said pawl may be actuated.

In witness whereof I have hereunto set my hand in the presence of two witnesses.

EDMOND FOURNIER.
