LOOSE-LEAF BINDER.

SPECIFICATION forming part of Letters Patent No. 768,256, dated August 23, 1904.

.Applicationled April 25, 1904:.

Toul/Z wwni, t may concern:

Be it known that I, IVAN Winn. a citizen of the United States, residing at Chicago, zin the ycounty-of Cook and State `of Illinois, have invented certain new and useful Improvements l in Loose-Leaf Binders, of which the following is a specification.

rlhis invention, as stated, relates `to looseleaf binders, and refers particularly to' an improved means for expanding and contracting tedline 2 2 of Fig.. 1.- Fig. 3 is a longitudinal central section through the binder, and

Fig. 4 is a perspective view of one of the saddle blocks forming part of the adjusting mechanism. l l

In the embodiment herein shown of this invention I provide a longitudinal back member 1, curved in cross-section and provided with .the integral end pieces 24and 3, the former of which has an opening 4. for receiving a socket key or wrench (not shown) by means of which the binder is expanded and contracted. On its inner 'concave side the backI 1 has two longitudinal ribs 5 extending parallel with each other andforming between them a groove 6. Intermediate their ends the ribs 5 have an opening 7, and'at theirends said ribs are provided with the raised portions 8 for receiving guide-plates 9, secured in any suitable manner, as by the screws-10, tothe raised` portions 8 of said ribs. Near its opposite ends the groove 6 is provided withthebearings 11.

An operatingshaft 12 is adapted v to lie within the groove 6 andl at its'opposite ends is provided with the reduced portions 13 for the bearings 11. One of its ends is also squared, as at 14:, to receive an operating key or wrench. Near its center the shaft 12 isl fitted with a fixed collar 15,'adapted to lie within the opening 7 in the ribs 5,l and at each side of said collar the shaft is provided with Serial Nb. 204,781. (No model.)

right and left hand screw-

threads

16 and 17, y

` respectively. f

Side members 18 and 1.9 are adapted to have aslidingengagement with the back 1. They are respectively provided with ends 2O and 21 and slide beneath the guide-plates 9, the ends201and 21 passing between the end pieces 2 and 3 of the back and the outer edges of l said guide-plates. y

Saddle-blocks22 and 23 are mounted upon the operatingshaft 12 and are internally screw-threaded to correspond with the screwthreads 16 and .17 on said shaft. The upper faces of the saddle-blocks are provided with two Wedging-points 24 and 25,' facing each other. A cover-plate 26 is secured to `the upper face yof each saddle-block by means of screws v27.

Operating-rods 28 in pairs, rigidly secured at one( end to the

side members

18 and 19, near the middle portions thereof, extend diagonally across the binder, the rods of each pair crossing each other between the wedges 24 and 25 of one of the saddle-blocks.

Telescoping leaf holding pins 29 of the usual construction are mounted upon the

side members

18 and 19, and said side members also carry the usual hinged covers 30.

To open or close the binder, a socket-key is placed upon the square 4 portion 14 of the 'operating-shaft, 12 and said shaft rotated.

A rotation of the shaft imparts a longitudinal movement to the saddle-blocks 22 and 23, said blocks sliding upon the ribs 5. A movement of the blocks toward theends of the binder moves the point of crossing of the operatingrods 28 of each pair toward the ends of the binder, and therefore will cause the sides of the binder to move outwardly. A rotation of the operating-shaft in a contrary direction moves the' saddle-blocks toward the center of the binder, moving the 'point of crossing of IOO my invention without departing from the spirit and scope thereof. Therefore I desire to have it understood that I do not limit myself to the particular construction herein shown and described.

I claim as my inventionl. In a loose-leaf binder, in combination, two side members slidabl y supported with relation to each other; two rods crossing` each other; each rod being rigidly secured at one of its ends to one of said side members; and means for changing the point of crossing ot' said rods to move said side members toward or from each other.

2. In a loose-leaf binder, in combination, a back member; two side members slidably snpported with relation to said back member; two rods crossing each other; each rod being rigidly secured at one of its ends to one of said side members; and means for changing' the point of crossing ot' said rods to move said side members toward or from each other.

3. In a loose-leatl binder, in combination, two side members slidabl y supported with relation to each other; two rods crossing each other, each rod being rigidly secured at one of its ends to one of said side members; a member embracing said rods at their point of crossing; and means for moving said member at a right angle with the line ot' movement oi' said side members.

4. In a loose-leaf binder, in combination, two side members slidably supported with relation to each other; two rods crossing each other, each rod being secured at on(` oll its ing; and a shaft having' a scre\\'thread engagement with said member for moving said member ata rightangle with the line ol movement of said side members.

In a loose-leaf binder, in combination; two side members slidably supported with relation to each other; two pairs ol rods; the

rods of each pair crossing each other, each rod being secured at one oi its ends to one ol said side members and the two pairs extending in opposite directions; a member for each pair or' rods; said member embracing said rods at their point of crossing; and means for moving said embracing members in opposite directions.

6. In a loose-leaf binder; in combimltion; two side members slidabl)v supported with relation to each other; two pairs ol rods, the rods of each pair crossing each other, each rod being secured at one ol its ends to one of said side members and the two pairs extending in opposite directions; a saddle-block `lor each pair of rods; said saddle-block embracing said rods at their point of crossing; and a shaft having a screw-thread engagement with said saddlc-blocks flior movingl said' saddle-blocks in opposite directions.
