LOOSE-LEAF AND cannon BOOK.
Application fil ed. April 10, 1919.
T 0 all w 7mm it may concern:
Be it known that I, Gnonon A. DUOHARME, a citlzen of the United States, and a resident of Medford, in the count of Middle sex and Commonwealth of 1V assachusetts, have invented certain new and useful Improvements in Loose-Leaf and Carbon Books, of which the following is a full, clear, and exact specification.
It is customary in many lines of business to use as a vehicle for duplicating orders, a book containing a number of loose-leaf blanks and a sheet of carbon paper by means of which to make the duplicate. This invention relates to improved means for removably holding the loose blanks, and also for holding the sheet of carbon paper.
Ordinarily, there are two separate sets of blanks in the same book, a sheet of one set receiving the original order, and a sheet of the other set receiving the carbon copy; but inasmuch as the improved device for holding one set is like that for the other set, I show only one thereof in the drawings.
Referring to the drawings forming part of this specification, Figure 1 is a side view of a single cover of a book provided with my improved device. Fig. 2 is a sectional side view of the same. Fig. 3 is a plan view of the same. Fig. 4 is a side view of the device open, and Fig. 5 is a perspective view of the main clamping means.
The reference numeral 1 designates a book cover or a pad carrying my improved fastening device, the latter consisting of three members, the bearing plate 2, the spring plate 3 and the attaching hooks 4. The bearing plate 2 is riveted or otherwise fastened to the cover 1, and has a flange 5 along its edge adjacent the near end of the cover 1, and a groove 6 spaced therefrom. The spring plate 3 is riveted or otherwise fastened alon one edge to the plate 2 with its opposite edge almost touching the inner surface of the flange 5.
The two attaching hooks 4 are united by a flattened bar 7, the parts being preferably made from a single length of wire with its extremities bent as shown and its intermediate linking portion 7 flattened. This link 7 is introduced beneath the spring plate 3 within the groove 6, the parts being so proportioned, and the link 7 being so canted, that the spring plate presses upon the edge Specification of Letters Patent.

of the link in a manner to hold the ends 9 of the hooks 4 firmly against the plate 2, as indicated in Fig. 1.
hen the hooks are forced over to the position shown in Figs. 2 and 1-, their ends 9 can readily receive the holes punched in the blanks, the cover 1 being supported at an angle in order to present the ends 9 nearly vertical for the more convenient application of the blanks. When a suitable number of the blanks have been placed upon the hooks, the latter are snapped over until their points 9 are pressed solidly upon the plate 2. This brings the points below the level of the spring plate upon which the pile of blanks rest, and thereby insures that not even the lowermost one of the blanks can be accidentally drawn away from the control of the hooks.
Further, while the hooks 4 are turned over and supported by the flange 5 as shown in Fig. 4, there is ample space between this flange and the edge of the spring plate for the introduction of a sheet of carbon paper 10, so that when the hooks have been returnedto their normal position, the spring plate grips the carbon paper between itself, the flange and the plate 2 and holds it against accidental withdrawal. After being thus secured in place, the carbon paper is folded over the outermost of the blanks, and the blank to be the original is laid upon the carbon paper and then written upon in the usual manner.
lVhen a supply of blanks has been used and torn out one by one, the hooks a can be tipped back and a fresh quantity of blanks applied, the carbon paper being at the same time removed and a fresh sheet substituted.
The especial value of my improvement consists in the form and employment of the highly arched hooks 4 adapted to have their free ends 9 swung away from and returned to the plate 2. Thus constructed, none of the upper blanks of a quantity held by the hooks can possibly be disengaged therefrom without tearing them forcibly away; and even the lowest ones are practically almost as secure, since'the ends of the hooks descend beside the ends of the spring plate 3 and thereby keep the sheets from being drawn out from between the ends of the hooks and the plate 2. In all other devices of the kind with which I am familiar, any wear or weakening of the spring action on the looking devices, causes them to' easily 7 I also find that the form of hook set forth hereinv is more easily supplied with fresh 7 blanks than are any others of which I am aware. The expense of manufacturing these loose leaf and carbon books is lower, too, than is the case with most other makes. The neatness of appearance of this new construction is a further item in its favor.
lV hat I claim is V 1. The combination with a support having an upturned flange along one edge, of a pair of hooks rigidly connected and pivoted to said support, the pivotalaxis being parallel with said flange and each of said hooks being in a plane at right anglesto the axis, and a spring plate attached to said support to engage the connecting portion between said hooks and located between saidhooks to permit their free ends to de scend close beside its ends to the surface of the said support, said connecting portion of the hooks being so formed that the free 7. ends of said hooks are normally spring held in engagement with the support.
single length of wire having its terminal sections formed intohooks in planes at right angles to the intermediate section of the wire, said intermediate section having a flattened portion and locatediwithin said groove beneath said spring plate.
In testimony that I claim the foregoing invention, T have. hereunto set my hand this 28th day of March, 1919. GEORGE A. DUCHARME;
