Application september 10, 1942, seriarNo. 457,823 solams. (o1. 12s-12) g `-"lhis"invention 'relates `to loose leaf rbinders of the typeA having sheet impaling posts, upon `which posts is formed one element of a means for securing together the locking bar and said posts to` hold the follower blocks in position where the `loose leaf sheets in the binder 'are maintained inthe lform of a compact filler.

' ltime of the primary aims of "this invention is the provision of `a post binder of loose vleaf char'- acter, the parts whereof are constructed of inexpensive, easily procurable material obviating thenecessityof employing' metal springs, binders board, canvas 'and metal parts, all accomplishing theresult vof" presenting a strong, vdurable and satisfactory sheet holding device that may beinexpensively manufactured Yand created of `materials not `now vitally essential `to the defense program.4

A,further object of the invention is to provide 4a loose V'leaf binder with a specially formed lock"- ingb'ar, capable of ,co-acting with apair of posts, the inherent 'characteristics of'whi'ch bar and posts vpermit 'manipulation to lock and unlock the 'binder as it becomes desirable to remove one 'of the covers for, the placement 'or withdrawal of a portion of vthe ller.

y Minor, objects of the invention are inestimportant .since the same include specific details of construction respecting the manner of 'form-ing the locking bar, 'the posts, and the follower blocks, yand therefore; ia4 number of objects of lesser importance will be 'foundv in the following" specification, referring to the ac'coipanying` drawing, wherein:

. 2 is a side elevational view of the same. Fig. f3`s a back view thereof;` and f f.

Fig. 4 is an enlarged detailed fragmentary sectional view taken on lineIV---IV of Fig. 1.

The component parts of a post binder made in accordan'cewith my' invention, are substantially the same as those heretofore used in creating loose leaf equipment of that character and include two follower blocks B and 8, both of which have a cover I0' connected thereto by a hinge I2. Covers I0 and hinges I2 are similar in nature and therefore, interchangeable during the manufacture of the equipment. Follower blocks 6 an 8, as Well as covers I 0, are made of thin sheets of wood and if desired, may be ply-Wood without covering.

The proximal edges of covers I0 and follower blocks 6 and 8,as the case may be, are grooved hinges are formed of fabric and held in place by glue or cement strengthened, if desired, by'

transverse pegs i3. Bevelling of the edges of follower blocks 6 and 8 and certain edges of. covers I may 'be desired, and if so, a milling operation will accomplish the result.

Fc-llower block 6 has at least two spaced apart perpendicular posts I4, each rigidly anchored thereto through the medium of a cross pin IVEv that is driven to position after one end of post E4 is introduced to the opening I 8 formed in follower block 6.

`Posts I4 receive sheets 20, the character of which is conventional. These sheets are punched with centers corresponding to the distance beg tween the axes of posts I4, and therefore, when nner.

follower block 8 `and the hereinafter described locking bar is lifted from posts I4, sheets 20 may bel moved to and from their position in the -i'taoh post I4 is provided with teeth or serrations formed as shown in Fig. 4, to present a series of shoulders 22 beneath which a portion of locking -bar 24 is engaged when the binder parts are operatively assembled. Shoulders 22 are preferably milled in the outer sides of posts I4.

The proximal sides of posts I4 are smooth, and

therefore, when posts I4 are flexed toward each other, the portionsof locking bar 24 engaged beneath shoulders 22 are disengaged and bar 24 is easily lifted from a-positionagainst upper follower block 8.

In producing posts I4 a good grade of wood., hard enough to maintain shoulders 22 in good condition during use, must be employed and the material'fro-m which locking bar 24 is constructed should likewise beof a hard wood, suitable for engagement with shoulders 22 as shown in Fig. 4. A tongue 26 is formed `on locking bar 24 adjacent to each end thereof and within a perfo-- ration lthrough which a post I4 must pass when bar 24A is forced against block 8. Perforations 28 are at least as great in diameter as the diameters of posts I 4 and when said posts are 'to receive the marginal edges of hinges I2.` Said 55 rawn toward each other, tongues 26 are out of engagement with shoulders 22.

Locking bar 24 is initially relatively thick but its central portion is longitudinally cut away as at 3Q and its ends are similarly reduced in thickness to form spaced contact points 34 on the lower surface of the bar. The ends of bar 34 are thus spaced above the follower block 8 and this spacing, together with cavities 32 formed in the'upper face of the block, permit insertion of the fingers of the operator between the block and the ends of the bar for removing the latter when the upper ends of posts I4 are manually flexed toward each other to disengage tongues 26 of the bar from shoulders 22 of the sts.

poLocking bar 24 has its points of contact 34 with follower block 8 adjacent to posts I4 and between the same to prevent any objectionable rocking action and to impart a holding action near the interlocked elements 22 and 26. Openings I9 in follower block 8 are slightly larger in diameter than posts I4, or of a size sufficient to allow the respective entering posts I4 to flex an amount capable of freeing tongues 26 and shoulders 22.

Shoulders 22 may be formed in the inner or proximal sides of posts I4 and the position of tongues 26 changed accordingly. In such arrangement, the posts are flexed from each other when the locking bar 24 is released. The outer faces of posts I4 are smooth and an upward force at the center of bar 24 will be ample to arch the same and thereby shorten the distance between the free ends of tongues 26. This, to-

i gether with an outward flexing of the posts aspairof posts formed of relatively flexible inate- Y rial; a follower block provided with post-receiving openings; a locking bar having perforations therethrough to freely receive the posts respectively; and interlocking means formed on the posts and the locking bar to hold the latter in engagement with the former, said locking bar having ai contact point thereon adjacent to each perforation for contacting engagement with said follower block, the portion of the locking bar intermediate said points and the portions of the bar frornsaid points to the ends of the bar being spaced from the follower block.

In a binder of the character described, a pair of posts; a follower block provided with post receiving openings; a locking bar having perforations therein to receive the posts respectively;v and interlocking means formed on the posts and locking bar to hold the latter in enpair of posts formed of relatively flexible material; a follower block provided with post-receiving openings; a locking bar having perforations therein to freely receive the posts respectively; and interlocking means formed on the posts and locking bar to hold the latter in engagement with the former, said interlocking means comprising a series of transverse, spaced apart shoulders formed on the posts, and tongues integral with the locking bar, engageable successively with said shoulders and disengaged from the shoulders by flexing of the posts to vary the distance between the latter.
