I Filed March 50, 1938 nrrok/va v Patented Jan. 31, 1939 PATENT OFFICE 2,145,780 MEMORANDUM APPLIANCE Harold Julian Wilberforce Raphael, London, England, assignor to Raphael Industries Limited, London, England, a British company Application March so, 1938, Serial No. 198,992 In Great Britain June 1, 1937 1 Claim.

This invention relates to a memorandum appliance and it has for its object to provide a novel device of this character in which the writing surface is renewed by the folding action of a rotating member on a length of paper.

Such an appliance may broadly comprise a plate of wood or other suitable material which is mounted upon, and so as to rotate between, a pair of pivoted arms to constitute a supporting surface for the paper when writing and a means of withdrawing the paper from a roll or other supply by causing the paper to wrap itself around the plate when the plate is rotated to provide a fresh writing surface twice in each revolution or by pulling on the paper to cause the plate to rotate in a reverse direction and the paper to unwrap therefrom. In order that the invention may be clearly understood and carried into effect an embodiment I of the same will now be described by aid of the accompanying drawing in which Fig. 1 is a perspective view showing one form of memorandum appliance according to this invention.

Fig, 2 is a section on the line 2--2 of Fig. 1. Fig. 3 is a section on the line 3-3 of Fig. 2. The memorandum appliance illustrated comprises a pressed or moulded casing at, having vertical sides b for the revoluble support of a detachable roll 0 of paper and a sloping upper surface cl forming a support for a plate d. This plate is arranged to revolve about its transverse axis by being mounted between the inturned extremities e of a pair of arms 1, which in the example illustrated are formed integral with a transverse portion 9, by bending to form, a single piece of wire. This transverse portion g forms a hinge for the arms and the plate (1 by being secured within transverse slots or bearings. h 1 formed on the inside of the casing a the free movement of the arms '1 being permitted by cutting away a portion of the sloping surface d of the casing a.

The paper is wound into a roll upon a wooden bobbin 1' and this is totally enclosed and revolubly and detachably mounted between the sides b by means of pintles which have enlarged heads k,

inner ends in the form of wood screws Z to be screwed into opposite ends of the bobbin 7' and an intermediate portion m forming a bearing or journal to enter corresponding and opposing may be varied by screwing inor out the pintles on which the springs are mounted.

The free end of the paper on the spool is fed through an opening p in the casing and is glued or otherwise aflixed to one narrow end of the plate and by turning the plate over about the inturned extremities e the paper is folded longitudinally around the plate to provide the required writing surface which is renewed twice in each revolution of the plate. 10

If it is required to inspect notes on a previously used surface the plate is caused to rotate in the opposite direction by the operator revolving the spool by aid of one of the aforesaid headed pintles, thus causing an unfolding of the paper from the plate and its re-wind onto the spool.

The action of the plate and its mounting during the folding or unfolding of the paper is illustrated in Fig. 3 which shows the plate in one of the positions it assumes when revolving.

The turning of the plate to renew a writing surface is, in the example illustrated, effected by hand.

In the example illustrated the sides of the casing a project above the level of the sloping surface d thereby forming a recess in which rests the plate e and arms ,f. I

The casing a is also formed with a recessed portion q for the reception of a calendar or a card bearing advertising matter, which is held in position by slipping the corners beneath ledges r provided in the recess.

A pencil or pen tray 3 is provided at the rear end of the casing and is formed integral therewith or may be detachably secured thereto.

What I claim is:-

A memorandum appliance comprising, in combination, a base member, housing means at one end of said base member for the revoluble support of a roll of paper and having an exit therefrom for the paper, a substantially horizontal flat supporting surface forming the top of said base member, a revoluble plate normally resting fiat upon said fiat supporting surface to constitute a support for the paper when writing, and a pivotal mounting for said revoluble plate comprising a pair of arms hingedly attached to the base member adjacent one end of said fiat supporting surface, and between the outer ends of which arms the revoluble plate is mounted to rotate whereby said plate may be swung upwards above the plate supporting surface and then revolved to withdraw and enfold about itself paper from said revolubly supported roll of paper when the writing surface requires to be renewed. 55
