BOOK AND SIMILAR BINDING.

Application filed February 11,1921. Serial No. 444 138.

1 00M whom it may. concern:

B'fl'dt known that I, WILLIAM P. Prrr, a

citizen of: the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented a certain new and useful Improvement in Book and Similar Bindings, of which the following is i a specification.

My invention relates toimprovements in booltv and similar binding. It relates particularly to an improved hinge construction for connecting cover members of a book or temporary binder.

The object of my} invention is to provide a. hinge constructionof the kind described, which-is simple,cheap to make, strong and durable, not liable to get out of order, and which will permit the cover members to be machine bound at a. minimum of expense.

My invention provides still further a novel method of making a hinge cover member.

The novel features of my invention are hereinafter fully described and claimed.

In: the accompanying drawing, which illustrates the preferred embodiment of my invention,

Fig. 1 is a perspective view, partly broken: away, of twocover members of a binder provided with my improvement.

Fig. 2 is a plan view of one of thecover members, partly broken away, showing the sheet of binding material applied to one side of the body and its projecting edges unfolded.

Fig. 3is an enlarged cross section on the line 3'3 of Fig. 1.

Fig; 4- isan end elevation of the two cover members and hinge.

Fig; 5 is an end elevation ofthe channel member before it has been compressed, and the body disposed therein.

Fig. 6 is an end elevation showing the channel member attached to the body.

Fig. 7 is a perspective view of the channel hinge member before it has been compressed to its operative position.

Similar reference characters designate similar parts in the diflerent views.

In the drawing, which illustrates my improvement applied to a loose leaf post binder, 1 designates one member of the binder cover having mounted thereon the usual posts 2, and which is provided with one or more pintle barrels 3 arranged to receive a pintle 4,. to which the swinging cover member is hinged. The swinging cover member comprises afiat body 5, prefera'bly of thick card board, and which is embraced at the side adjacent to the memher 1 by a channel member 6,.which forms one member of the hinge, the member 6 being spaced apart from the body 5,.the pin+ tle 4 extending through the space thus provided. The channel member- 6 is provlded on eaclr flange with one or more prongs 7 whichenter the body 5, Fig. 6. The prongs 7 of the two sets are, preferably disposed respectively in different transverse planes andin staggeredrelation to each other. By means of this arrangement the opposite projections do not interfere with each other and the body is not materially weakened along any one line.

The body 5 extendsbeyond the ends of the member 6 a distance corresponding to the lengths of the barrels A sheet of binding material 8 is fastened I by gluing or otherwise to one side of the body 5,.and has-its edges extending beyond the edges of the body and beyond-the member 6 during the process of manufacture. The sheet 8 has at one end a. rectangularfiap 9, which is folded over the: member 6 and is fastened to theiopposite side ofthe body 5. The sheet 8 also has at the ends of the flap 9 two triangular flaps 10 which are folded over the adjacent edge of the body 5 and are attached to the inner side of the body 5, as shown inFig. 1. An inner lining sheet 11 may beglued to the inner side of thebody, after the remaining extending. portion of the sheet 8" has been folded-over the body and attachedto the inner side thereof, the lining. 11 being extended over and secured-to the folded over portions of the sheetS.

The channel member (5 is made, preferably, of'thin metal so as to be inexpensive, and sothat it will not rise but a trifle above the surface of the body 5. This construction permits the cover to be machine bound and avoids expensive hand binding.

It will be noted by referring to Figs. 5 and 7 that the channel member 6, before being applied to the body 5, is V-shaped, so as to permit its being readily slipped over the end of the body 5. When properly positioned on the body 5, the member 6 is compressed so as to embrace the opposite sides of the body and so as to cause the prongs 7 to enter the body.

The binding sheet 8 in addition to serving as a finish also re-enforces the channel member 6 and helps to hold the latter firmly attached to the body.

While I have shown the improvement applied to a loose leaf binder, it 'will be obvious that it may be applied to books and to loose leaf holders of different types, and the hinge construction may be applied to many uses in which it may be desired to employ a cheap, strong and serviceable hinge.

I do not limit my invention to the structure shown and described, as many modifications, within the scope of the appended claims, may be made without departing from the spirit of my invention.

' What I claim is 1. In a device of the kind described, a cover member comprising a flat body, a channel hinge member embracing one end of the body, a space adapted to receive a pintle being provided between the hinge member and the adjacent edge of the body, and a binding sheet embracing the hinge member and the body, substantially as set forth.

2. In a device of the kind described, a cover member comprising a flat body, a channel hinge member embracing one end of the body, a space for receiving a pintle being provided between the hinge member and the adjacent edge of the body, the body extending a substantial distance beyond each end of the hinge member, and a binding sheet covering one side of the body and being folded over the edges of the body and the hinge member and'attached to the other side of the body, substantially as set forth.

3. In a device of the kind described, a cover member comprising a fiat body, a channel hinge member embracing one end of the body, and having one or more projections entering the body, and a binding sheet folded over the hinge member and attached to opposite sides of the body, a space being provided between the hinge member and the adjacent edge of the body for receiving a pintle, substantially as set forth.

l. In a device of the kind described, a cover member comprising a flat body, a channel hinge member embracing one end of the body, the latter extending a substantial distance beyond each end of the hinge member, and a binding sheet being folded over the hinge member and the adjacent exposed edge of the body and attached to opposite sides of the body, a space being provided between the hinge member and the adjacent edge of the body for receiving a pintle, substantially as set forth.

5. In a device of the kind described, two cover members, one comprising a flat body, a channel hinge member embracing one end of the body, a space being provided between the hinge member and the adjacent edge of the body, and a binding sheet folded over the hinge member and attached to opposite sides of the body, the other cover member having one or more barrels, and a pintle mounted in said space and in said barrels, substantially as set forth.

6. In a device of the kind described, two cover members, one comprising a flat body, a channel hinge member embracing one end of the body and having one or more projections extending into the body, a space being provided between the hinge member and the adjacent edge of the body, and a binding sheet folded over the hinge member and attached to opposite sides of the body, the

other cover member having one or more barrels, and a pintle mounted in said space and in said barrels, substantially as set forth.

7. A hinge comprising two members, one having a barrel, the other member comprising a body and a channel member embracing opposite sides of the body, a space being provided between the channel member and the adjacent edge of the body, a binding sheet embracing the channel member and embracing and attached to opposite sides of the body, and a pintle mounted in said space and in said barrel, substantially as set forth.

8. A hing'e member comprising a body, a channel member embracing opposite sides of the body, a space being provided between the channel member and the adjacent edge of the body adapted to receive a pintle, and a binding sheet embracing said channel member and embracing and attached to opposite sides of the body, substantially as set forth.

9. A hinge member comprising a body, a channel member embracing opposite sides of the body and having one or more projections entering the body, a space adapted to receive a pintle being provided between the channel member and the adjacent edge of the body, and a binding sheet embracing said channel member and embracing and attached to opposite sides of the body, substantially as set forth.

In testimony whereof I have signed my name to this specification.

WILLIAM P. PITT.
