G. W. BROWN. MEMORANDUM BOOK 0R PAD.

(Na-Model.)

UNITED STATES PATENT OFFICE- GILMAN WV. BROWN, OF WEST NENVBURY, MASSACHUSETTS.

MEMORANDUM BOOK OR PAD.

SPECIFICATION forming part of Letters Patent No. 500,736, dated July 4, 1893. Application filed January 14:, 1893. Serial Il'o.4=58,354. (No modeh) To all whom it may concern.-

Be it known that I, GILMAN W. BROWN, of West Newbury inthe county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Memorandum Books or Pads, of which the followingis a specification.

This invention has forits obj ect,first, to provide a memorandum book of such construction that the leaves or sheets can be swung horizontally, so that those that have been written upon may be readily displaced to expose the unused leaves, and can be readily detached from the book and filed for future reference.

The invention also has for its object to enable each leaf to be notched or recessed by the user after it has been written upon, so that a portion of the upper unused leaf can be reached by the finger and held while the leaves which have been notched are being displaced.

To these ends the invention consists in the improvements which I will now proceed to describe and claim.

In the accompanying drawings, forming part of this specification: Figure 1 represents a perspective view of a closed memorandum book constructed in accordance with my invention. Fig. 2 represents a perspective view, showing the cover of the book displaced to expose the leaves below it. Fig. 3 represents a top view, showing the book closed and port-ions of the cover broken away. Fig. 4 represents a section on line 4-4, Fig. 3. Fig. 5 represents a section on line 5-5, Fig. 3. Fig. 6 represents aperspeetive view, showing parts of the back or holder and of the cover.

. The same letters of reference indicate the the same parts in all the figures.

In carrying out my invention, 1 provide a back or holder a, which is preferably of comparatively stiff material, such as card-board or paste-board, covered, if preferred, with a suitable leather or other desirable covering material. To one end of said cover is affixed a stud or pin b, which projects upwardly from one side of the holder near one end thereof, said pin being provided at its upper end with an ear or projection 11, so that the upper end of the pin is substantially key-shaped. The pin 1) is preferably rigidly secured to the preferably somewhat less in area.

holder to by means of a plate 12 to which the pin is rigidly affixed, said plate being inserted between the parts of the holder (1, as shown in Figs. 4 and 5. v

0 represents a memorandum blank or pad, composed of a series of superposed sheets of the same general form as the holder at, but Each sheet of the pad has three perforations, c and c 0 (Fig. 3.) The perforation c of each sheet is arranged to coincide with the pin b, said perforation being key-shaped, so that, when a sheet is in a given position with relation to the holder, the perforation 0' will pass over the outer end of the pin 1), and, when said sheet is turned to another position, the offset portion of its hole 0' will be out of register with the projection 12 of the pin, so that the pin will hold the pad in place upon the holder. The perforations c c are arranged at the same distance apart in all the sheets, so that, whenever a sheet is detached from the pad, it may be filed by engaging the holes 0 c with suitable pins forming a part of a filing device. 7

d represents a cover, which is provided at one end with an orifice d, having the same form as the outer end of the pin 1), and arranged like the orifices c in the sheets of the pad 0, so that the cover can be secured to or engaged with the pin in the same manner as the pad. The cover is or may be made of a suitable comparatively stiff material, such as is generally used for the covers of pocket memorandum books, but is preferably more flexible than the holder at. I prefer to make the cover comparatively stiff at the end that is engaged with the pin (1, and to this end I insert between the parts or layers of the cover a plate d of sheet metal, having a hole 01 for the pin 6. The part at of the cover immediately adjoining the end thus stiffenedispreferably made quite thin, so that it is more flexible than the main portion of the cover, the thin portion (1 constituting a hinge or joint, which enables the main portion of the cover to be readily swung backwardly, if desired. It will be seen that the pin b constitutes a pivotal connection between the pad 0 and cover cl and the holder 0,, enabling the cover and any desired number of the sheets of the pad to be displaced to expose the other sheets, by a lateral swinging motion, the sheets of the pad having no connection with each other excepting that afforded by the pin 1). Consequently, when any sheet has been written upon, said sheet may be displaced to expose the next sheet, by swinging the sheet around on the pin so that it will project away from the upper end of the pad in the same direction that the cover d is shown as projecting in Fig. 2, the cover being, of course, displaced with the sheet or sheets that have been written upon. It will also be seen that the described connection of the sheets of the pad to the holder, and the provision of the filing orifices 0 0*, enable the user of the book to readily detach any sheet by tearing it from the pin b, and to preserve the detached sheet for future reference by engaging the pins of a filing device with the orifices c 0 To enable the user to readily find the highest unused sheet of the pad, I weaken or perforate each sheet along a line located near one edge of the sheet, said line being so formed that the removal of the portion of the sheet between it and the edge of the sheet will form a notch or recess in the sheet, the lines of perforations in all the sheets coinciding, so that a recess formed in one will coincide with a recess formed in another.

In Fig. 3, I show a row of perforations composed of an elongated curved perforation e and a row of small perforations 6 extending from each end thereof to the edge of the sheet. Said perforations are formedin the outer end of each sheet, and are formed on a curve, so that, when the portion of the sheet bounded by said perforations and the edge of the sheet is torn away, an operation which is rendered easy by the insertion of the finger nail in the perforation e, a recess will be formed in one edge of the sheet, said recess being of suitable form to permit the user of the book to place his thumb on the bottom of the recess, and thus hold down the sheets which have been recessed. It will be seen that this arrangement enables the user of the book to recess each leaf after it has been written upon, so that, when he next uses the book, he can readily find the topmost unused leaf by inserting his thumb in the recessed end of the pad and holding down the leaves that have not been recessed while he displaces the recessed leaves.

It will be observed that the pad and cover can be readily applied to and removed from the holder, so that the possessor of a holder and a cover of the construction above described can readily provide himself with a new memorandum book by inserting a fresh pad therein, it being my intention to provide pads or packs of superposedsheets, constructed as already described, so that they can be used in such quantities as the consumer may desire.

A memorandum leaf, perforated as above described for engagement with a pivot and with the studs or pins of a filing device, constitutes a new article of manufacture, which may be sold in packs by Stationers.

I claim- 1. A memorandum book, comprising a holder or back having a key-shaped pin, a pad or block composed of superposed independent sheets each having a key-shaped orifice formed to receive said pin, andanindependent cover also having a key-shaped orifice, said cover and sheets being adapted to be displaced by a swinging movement on said pin, as set forth.

2. A memorandum book, comprising a holder or back having a rigidly-attached keyshaped pin, a pad or block of sheets perforated to engage said pin, and an independent cover having at one end a plate provided with a key-shaped orifice formed to engage said pin, as set forth.

3. A holder for a memorandum block or pad, consisting of a flat back having a key-shaped pin projecting from one of its sides near one end, and an independent cover havinga keyshaped orifice formed to engage said pin, as set forth.

4. A memorandum book, comprising aback or holder, having a stud or pin projecting from one of its sides near one end, and a pad composed of a series of superposed independent sheets, each perforated to receive said pin, and additionally perforated to engage filing devices the sheets being connected in a series only by the pin, whereby each sheet is enabled to swing edgewise independently of the others, the additional perforations enabling the leaves to be filed for reference after being torn from the book, as set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 12th day of January, A. D. 1893.

GILMAN W. BROWN.
