TEMPORARY BINDER.

SPECXFIOATION formingl part of Letters Patent No. 669,778. dated March 12, 1901.

Application iiled July 20, 1899. Renewed December 24,1900. Serial No. 40,973. (No model.)

fr0 t1/'L w/wm t may concern.:

Be it known that I, JOHN FERDINAND CORDES, a citizen of the United States, residing at Chicago,in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Temporary Binders, of which the following is a specification.

My invention relates to temporary looseleaf binders wherein any convenient number of letters, bills, or other sheets are held until they are ready to be permanently bound up or tiled away, and especially to that class of temporary binders which employ a bindingstrip having impalingpins affixed thereto and a clamping-plate having open slots from one side thereof to receive the pin and means for locking the clamping-strip thereon.

My invention consists in certain improved means for locking the clamping-plate upon the impaling-pins, as will hereinafter appear with reference to the accompanying drawings and particularly pointed out in the claims.

In the drawings referred to, Figure 1 is a perspective view of a temporary binder with my improvements applied thereto; Fig. 2, a perspective view of the two outer slotted plates of the clamping-strip and an impaling-4 pin held within the slot by myimproved lock; Fig. 3, a plan of the inner side of part of the outer 4plate of the clamping-strip, with the turn-button upon the outside thereof; Fig. 4,

a perspective view of the turn-button disconnected from the locking-dog and clampingstrip; Fig. 5, a plan of the parts shown in Fig. 2, with the locking-dog in position to open the slot of the clamping-strip; Fig. 6, a plan of the parts shown in Fig. 5 with the lockingdog in position to completely close the slot of the clamping-strip; Fig. 7, a plan of the inner plate of the clamping-strip, with the iinpaling-pin in section and the slot closed; Fig. 8, a plan of the locking-dog detached.

j'lhe cover A is hinged at a to the bindingstrip B, andthe cover A' is hinged at a' tothe clamping-strip C, the binding-strip B having impaling-pins D fixed securely thereto and the clamping-strip C having slots c' extending from the back edge thereof to receive the impaling-pins D, the said clamping-strip being provided with a locking device of novel construction to hold it securely at any required point upon the impaling-pins, the said device serving to completely uncover the slot when in one position, thus allowing the clamping-plate to be quickly withdrawn from the impaling-pins and completely removed from the leaves or sheets of paper held therein.

The clamping-strip C consists of three plates c2, c3, and c4, one placed upon the other and riveted together, all of the said strips being slotted from the back edge across to the middle of said plates to register one with the other to receive the im paling-pins D, the clamping-strips being thus made to facilitate the connection andinclosure of several parts of the lockingdevice, between the inner and outer surfaces thereof.

The locking device consists of a segmentshaped dog E, having a slot e at one end to receive a lugf upon the inner face of a turnbutton F, by which means it is secured fixedly thereto, and the said turn-button has a lon-v gitudinal slot f to conform to and register with the slot c of the clamping-strip. The outer plate c2 has a half-circle slot c5 to receive the lugf of the turn-button and allow it to rotate therein, and the middle plate c3 has a circular recess c6 cut out of it to receive the locking-dog E and allow it to rotate therein around the impaling-pin. The plates comprising the clamping strip are preferably made'of light metal, as aluminium, in which case an abutment-plate H, of hardened steel, is held in a recess c7, having irregular parallel sides, and the inner edge of the abuty ment-plate is made in a segment coincident with the edge of the circular recess c6 and eccentric to the path of movement of. the locking-dog, thus to press the said segmental-shaped locking-dog with ever-increasing force to bear against the impaling-pin and securely clamp the pin within the slot c' of the strip C, the locking-dog being projected completely across said slot and effectively barring the passage of the impaling-pin to the open end of the slot when the locking-dog is thus held by the turn-button, the latter also serving to bar the slot when the dog is turned and locked. The recess in the middle plate may be made concentric with the impaling-pin when the latter is in place, and the periphery of the locking-dog will then be made eccentric or wedge-shaped to accomplish the same IOO purpose-that is, to lock the impaling-pin with the slot when the turn-button and lock,- ing-dog are rotated upon the pin.

The distance moved by the locking-dog and turn-button is so great that but slight pressure is required by the button upon the locking-dog, the 'button being thus easily held by the fingers and turned freely. f

Any number of impaling-pins and turnbuttons and locks may be employed, and it one of said locks should become loose the other lock or locks will securely hold the clamping-strip in place.

I claim as my invention and desire to secure by Letters Patent- 1. A temporary binder comprising a binding-strip and an impaling-pin ixedly secured thereto and an adjustable strip having a slot leading from the edge thereof to receive the impaling-pin an eccentric abutment thereon a segmental dog to turn Within said eccentric abutment and a turn-button engaging with the dog and slotted to receive the impalingpin substantially as described.A

2. In a temporary binder the combination'A with a binding-strip of an impaling-piu afiixed thereto, aclamping-plate having an aperture to receive said piu, a turn-button attached to the clamping-plate perforated to it upon and oscillate around the impalngpin and a locking-dog supported upon and operated by the turn-button, the button being securedto the clamping-plate by means of the dog, substantially as described.

3. In a temporary binder the combination with a binding-strip having an impaling-pin aflixed thereto a slotted clamping-plate having a recess therein a segmental dog adapted to rotate Within said recess and clamp the impaling-pin and a slotted turn-button fitted upon the impaling-pin and attached tothe dog substantially as described.

4. In a temporary binder the combination With a binding-strip having an impaling-pin afxed thereto a slotted clamping-plate having a circular recess therein and an abutment plate providing a segmental eccentric section of the wall of said recess held to the slotted clampingplate, a segmental dog adapted to rotate upon the impaling-pin, to engage with said abutment-plate,and aslotted button attached to the dog for operating it substantially as described.
