LEI-TERv o R INVOICE FILE.

Seeoation forming part ef Letters'Patent No. 50,652, dated-October 24, 1865.

To all whom it may concern:

Be it known that I, REINHOLD BOEKLEN, of the city of Brooklyn, county of Kin gs, and State of New York, have invented certain new and useful Improvements in Lett'eror 1n voice Files;

and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to 'the accompanying drawings, in which-- Figure l represents an end view of my im-v proved le, the cover on' the end of the springcase removed and exhibiting the le open' and Athe paper flap turned back ready to receive 'a letter. Fig. 2 is a similar view, but the paper iiap is in a position after it has received and bound the letter. Fi g; 3 is a plane view of the same,'the relative position of the parts being shown the saine as in Fig. 1.

Similar letters of reference indicate corre.

u spending parts in the several'i'igures.

The first part of my invention consists in the I* use of a spring, is disconnected from the cam,

crank, or eccentric of the axial, rod of the binding-Hap, and is otherwise so applied with respect to it that it (said spring) alone serves to retain the flap in a position which will permit of the introduction of a letter or letters under vthe points of the binding-hooks, and also serve for forcing the iap and. letters over upon the hooks, and inthis condition retain the same until it is desired to take the letters again on? .the hooks. By this part of my invention the use ol' a catch-pin or other additional fastening' than the spring and eccentric of the axial shaft front edge of the flap bending it into a forni which approximates very closely a cyma reversa,

By this part of my invention a guide is provided, and' the letters can be filed against the same so as to have a uniform margin, and a large portion of the bulk of' letters are snp- 'ported at their backedge; and besides this a greatcr number of letters can be bound in a. le-

also admits .of its free edge resting down upon Y the inside ot' one of the backs of the le while the letters are being filed.`

To enable others skilled in the art to make l and use my improvements, I -will proceed to describetheir construction and operation.

A representsthe back of the le, which I make of metal or any other snitableniateral, in the shape of the back of a book. B Bl are the usual covers to the same, which are made of pasteboard. l

Gare the curved binding-hooks which stitch and hold the letters in their place.

D is the paper flap, by means of which the. binding-hooks are forced into the letters. This flap D is secured .to astrong wire,'E, which forms its axis to turn by, aud'is provided with oblongr holes F F-F F, to allow the lfile-hooks C C C O to work through, and thus to stitch through the letter. The plate ofthe iiap D is bent to form a shoulder` at Gr, against .which the edge ofthe letter is placed in order to guide the operator in binding or booking his letters or invoices at an even margin. Theend of the iap-plate is bent curved in order that easy hold can be taken of when the same is turned back, as clearly shown in Fig. 2.

The wire E rests in bearings, one being formed ,in the top end of the file at I and the other in the lower end of the file at the inner side of-the spring-box H at J, as clearly shown in Fig. 3.' The lower end -of the wire E projects to within the spring-box H, and to this .end of the wire E is attached or formed on an leccentric, K, which is acted upon by a dat spring, L, one/end of which presses against the that when the flap-plate D is oi' from the hooks G and pressed upon the cover B the largest radius of the eccentric K has just passed and is off to 'the right of a vertical radial line from the center of motion of the flap-plate D, so that the spring L, pressing vertically against the end of the eccentric K in this position, tends to-press they flapplate D upon the cover BA; but as soon as the Hap-plate D is raised a little by means of taking hold ofthe respective cover B', the end or the largest .radius of the eccentric K is brought to the left ot' the vvertical radial line from the center of motion of the' flapplate D, and the sprin g L acts on the voperating-face of the eccentric in a. tangential direction on the left side of the vertical radial line of the center of motion of the Hap-plate D, whereby the same is thrown toward the cover B on the right side of the vertical radial line of motion ofthe Hap-plate D..

In order to iile or book aletter the letter-file is opened, the flap-plate D turned oi from the .file-hooks C C C C, and the back edge of the letter is entered under the points of the hooks C CC 0over the plate D, against the shoulder G, as shown in Figfll by a red line. The flapplate D is 4now raised either by taking hold of the cover B and closing the letter-file or by taking hold of the nap-plate D itself and raising the same to forcethe letter onto thebind'- ing-hooks and hold it in place by the action of the spring L upon the eccentric K on wire E of the flap-plate D.

In place of the eccentric K, a camv or a crank supplied with a friction-roller may be used.

From the foregoing it will be clearly perceived. that by the employment of this device -to the le the same can be operated with one hand, and that it is more simple and more durable than those heretofore in use for` .the same purpose; also, that the paper-flap D, constructand stron gei` than those heretofore used.

I do not claim a binding-dep which is con- .nected to a spring and requires to be retained back by the hand or by a catch-pin; but

What I do claim as my invention, and desire to secure by Letters Patent, is

1. The employment of a spring which is dis-- connected from the cam, crank, or eccentric of the axial rod of the binding-flap, and applied to a letter-file so as 4to operate. in the manner substantially as herein described.-

2. The construction of the binding-Hap with a shoulder, and from said shoulder to its front' edge with a curved form, substantially as described, and for the purpose set forth.
