DESK R CQBINET FOR DISAPPEARING TYPE-WRITING MACHINES Original appIication filed July 23, 1914, Serial To all wltom it may concern:

Be it known that we, (Animal on VLnnsenouwaa and JUHANNl-IS'TACUMA, subjects ol the Queen of the Netherlands, the former residing; at Ai'i'istelveensehe Weg 139 and the latter residing at Nieuwc Zijds Voor burgwal 227, both in Amsterdam, in the Kingdom oi the Netherlands, have invented certain new and useful Improvements in or Connected with Desks or Cabinets for 'I')isappearing 'lype-lVriting Machines, of which the l ollowing is a specification, refer enee being had to the drawings hereto an neXed and to the figures and letters marked thereonthat is to say:

The present invention has reference to a deskhaving a typewriter mounted at the side in such a manner as to swing, in which the board supporting the typewriter is sus pended in the usual manner by ll'lilIlS oi a parallelogram of rods, and the weight oi. the inaehine is entirely or partially compensated by springs. 1 The object of the present invention is to simplify the raising and lowering of the typewriter.

According to the present invention, this is obtained by the fact that the parallelogramshaped guides are connected to the door of the case, in which the machine is kept when not in use} in such a manner that when the machine is raised, this door moves backward, under the supporting board of the machine into the case.

The improved device is shown in the accompanying drawings in which Figure 1 shows a vertical section through the case, the machine being out of use.

Fig. 2 shows the machine in position for typing.\

In Fig. l the typewriter is designated by 1. It rests upon the supporting board 2 I which is suspended by two pairs of rods 3,

4, pivotally connected to it, in such a mannor as to swing on the sides" ofithe case. The side of the case, the supporting board 2, and the two Pairs of rods 3, 4 form the well known parallelogram suspension. The

' springs 5 serve to compensate the weight of the typewriter. They are adjust-ably connected at their lower ends to the case, while their upper ends are provided. with eyes 6 through which a cross bar 7 is passed, which Specification of Letters Patent.

is connected at its ends to reciprocating 1e vers 8. These levers S arepivotally mounted on fixed journals 9 and jointed at their freeiends with the rods'lO which are ,in turn connected (at 11) to the hack rods 3 of the parallelogram.

With this arrangement, given adequate tension of the springs 5, it is possible to eompensate the weight of the typewriter almost fully, so that this may be. raised with the least possible eii'ort.

in addition to being attached to the connertiug rods ll). the hack rods 3 of the parallelog'ram are ronnerted to a further system of rods by means of which the door 12 of the case is moved in such a manner, when the machine is raised. that it sinks back under the. supporting hoard of the machine into the easing.

For this purpose, the door 12 is provided with side brackets or projections 13v with which the levers i i are at 15 connected pivotally. These levers 14 are pivotally mounted at 1t) on the casing, while their short ends 17 are" eonneeted, by means of connectingr rods 18. to the rods 3 of the parallelogram at the point 19 between the fixed pivotinn" point oi said r ds 3 and the point 11 at "hieh the eonneetiug rods of the weight compensation mechanism are jointed thereto. The joint between the side brackets or projections'lI, andthe levers 14: is situated at a determined distance from the ends 20 of these levers it which ends 20 are bent lat rally to form ahutnients 21 which come into contact with the door 12 of the case, and prevent this door from sinking down too far when opened. I

Now, if the machine is in the case, that is, in the position shown in Fig. 1, the followinn movements a e required in order 'to bring it into the rosilion For use, (Fig. 2

chine and the tcnnon of the springs 55, which are of slightly lower vnlum has to be overcome. i

Sin'iultnneolisly with this raising, the lever l4 turns about its journal 16 by the action of the prcs-asurc of the buck pamdlrdograin rod. 5), transmitted to its shorter end by the connecting rod 1.8.

When the machine has been cmnplctcly raised, the door lvl ol' the (use is brought, by this turning of the lever ail, into the ll h'h tion shown in Fig.

In order to lix the machine in the upper positioin locking: devices are provided on each side of the upporting board 2.
