`LOOSE-Llilll? BINDER.

f Application filed July 17, 191'?. Serial No. 181,061.
To all whom it 'may concern:
Be it known that l, JOHN Sor-range, a citizen of the Unitedr States, residing at Holyoke, Hampden county, Stateof Massachusetts, have invented certain new and useful lmprovements in Loose-Leaf Binders; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same.
This invention relates to certain new and useful improvements in a loose leaf binder and pertains more particularly to a hinge construction for the covers ofloose leaf transfer binders.
The primary object resides in an improved hinge knuckle or socket and the manner of mounting the same on the tubular bar or casing.
'The invention further resides in the features of construction and the arrangements of parts hereinafter described and claimed, reference being had to the accompanying drawing wherein,
Figure l is a fragmentary top plan of a loose leaf binder having the present invention incorporated therein;
Fig. 2 is a transverse section on line 2-2 of Fig. l illustrating more clearly the present embodiment of the invention;
Fig. 3 is a detailed elevation of a hinge knuckle, per se; and
Fig. 4 is a sectional view thereof taken on line lee of Fig'. 3.
ln detail, the drawing discloses a tubular casing or bar l and a cover member 2 of a loose leaf binder which are hingedly connected by the following construction.
The tubular bar l is preferably formed by bending a sheet of metal longitudinally to form upper and lower sides with its free edges constituting the inner end wall, said free edges being slightly spaced to receive therebetween the neck portions 3 of the hinge knuckles or pintle socket members ll.
Each pintle socket member is conveniently formed from a strip of metal bent midway of its ends to form a socket or knuckle part 5 from which the sides of the strip are extended to provide a comparatively reduced neck 3, said sides being then separated and extended in parallel relation to form the cheek pieces 6. Each cheek piece is formed with an outwardly extending tubularfsocket or eyelet 7.
rlhe tubular bar is formed in its upper and lower sides and at regular intervals with registering apertures for the reception of the'eyelets 7 which latter are then eX- panded to secure the cheek pieces 6 tothe bar. means for securing the socket members to the bar and at the same time a-H'ords a reinforcement for the latter. The neck 3 bef ing disposed in the slot of the bar serves as a sustainingspaeer for Vthe free edges of the strip which `define the slot.'
rlhe other hinge section 2 is preferably made of steel secured to a cover made of binders board and provided with the sockets 8 which register between the casing or bar sockets l to receive therewith the hinge pintle 9 and thus complete the hinge connection. lt is obvious that any` number of hinge knuckles may be employed, and while the invention is especially adapted for loose leaf transfer binders, it is also capable of use in atop lock binder or in other structures embodying a hinge connection.
The particular securement of the cheek pieces, while not interfering with the usual internal working parts of the casing, prevents the spreading or eXpansion of the tubular casing, and the neck portions, being interposed between the free edges of the casing, prevent collapsing of the latter. Thus, the casing is stilfened and reinforced throughout its length. Consequently, the casing may be constructed simply by bending over a piece of sheet metal, and thereby obviating the necessity of employing drawn or seamless tubing.
While l illustrate the integrally formed eyelet struck up at 7, as shown in Fig. 4L, still it is apparent that this feature could be varied by substituting therefor a separate rivet or eyelet, or l could spot weld, braze, or solder the cheek pieces 6 to the bar l and yet retain, in other respects, the features of the general construction as described in my invention.
What is claimed is l. In a loose leaf binder, a casing constructed by bending over a sheet of metal to form a tubular casing having its free edges This provides a simple and etlicientk defining a slot, lsaid casing having spaced sets of registering perforations, and a plurality of vhinge knuckles each formed of a strip'of metal bent transversely to forni a knuckle part and then extended to provide a neck portion for disposal in the casing slot to reinforce the casing against collapsing, the ends of said strip being extended from the neckportion in spaced relation to pro- Vide `cheekpieces,`each of'which is formed with an outwardly extending eyelet," the oppositely extending eyeletsY of each of the cheek pieces engaging in a set of registering l'aerforations'of' the casing and expanded to -15 secure the cheek pieces to the casing.
' L2. In-a hinge for loose leaf binders, a casing havinga pair of registering perforations, anda` slot, and a hinge-knuckle comprisin'g a 'pi'ntle receiving knuckle'part, a neekJpa-rt for disposal-in the casing slot, and spaced cheek pieces each having an outwardly projectingl eyelet engaged on one of the registering `perforations of the casing and'expanded for securing the cheekpieee in the latter.
3. In-aloose leaf binder, `a casing having registering openings, and a hinge knuckle having a support formed with oppositely extending eyelets engaging in the openings of the casing and expanded for securing the knuckle to the latter.
4. In a `loose leaf binder, a casing having registering openings, and a hinge knuckle having a part extending Within the casing and formed with rivets passing through the casing openings for securing the knuckle to the casing.
5. In` a loose leaf binder, a casing having registering openings, a hinge knuckle having spaced cheek pieces extending Within the casing, and means extending through the openings of the casing for securing the cheek pieces to the latter.
6. In a rloose leaf transfer binder in coinbination, an oval metal tube, a hinge sup- JOHN SCHADE.
