2 Claims.

This invention relates to typewriter supports, and more particularly to a type of support that can be built into or made a part of a desk, and will support a typewriter at various heights from the floor, making it more convenient for the user.

An object of my invention is to provide a separate unit that may be installed into a desk or table, adapted for its use, and so constructed as to permit a typewriter to be brought horizontally to its operative position at will.

Another object of my invention is to provide an adjustable support for a typewriter that will permit changing the height of the table to suit the users convenience.

Still another object of my invention is to provide a means that will conceal the typewriter, entirely, in a desk or table when not in use.

With the above and other objects which will be apparent as the description proceeds, the invention consists of the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the accompanying drawings:

Fig. 1 is a fragmentary perspective View of the mechanical unit showing the operative parts without the board support.

Fig. 2 shows another view of one of the side plates with a modified method of adjustment for height.

Fig. 3 shows the board support on which the typewriter is fastened, equipped with rollers to allow ease in raising the typewriter to its operative level.

Fig. 4 shows a cross sectional plan view of the device showing its operation.

Fig. 5 shows a front view of the device in position, and

Fig. 6 illustrates the entire assembly of the device attached to a conventional type of open top desk.

Referring to the drawings in detail, wherein like characters of reference denote corresponding parts, the reference characters It and II indicate right and left hand vertical plates held in position by the horizontal cross members I2, fastened to plates Ill and II at I8. There are channels I3, fastened in horizontal alignment to the inside of plates Ill and II and having similar channels I l and 2| with open ends I6 and I1 running in angular relation to the channel It. The horizontal channels I5 fastened longitudinally to the outside of the plates Ill and II, are held securely by means of screws in apertures at 34. These apertures 34 through the plates It and I I, are in vertical relation to each other and permit the channel I5 to be placed at either one of several heights as shown. I

The board support I9, supporting the typewriter 28, has rollers 24, 25 and 26 fastened to its sides, projecting outwardly from it. These rollers 24, 25 and 26 engage the channels I3 and allow horizontal movement of the board I9 in the channels I3. When the board I9 is forced back into the channel I3 the roller 24 enters the opening I! in the channel 2I, at the same time that the roller 25 enters the opening I6, in the channel I i, allowing the entire board I9 to descend in the angular channels I l and 2I. This is illustrated at 22 and 23 in Fig. 4: showing the descent of the board I9.

The entire unit with the channel I5 on the plates I0 and II, as guides, engage the rails 21 fastened on the inside of the space provided in the desk 28.

In Fig. 2 a modified method of raising or lower ing the entire unit is shown. The channels 29, supported by radial arms 30 and SI hinged at 33, replace the channels I5. There are apertures 32 in radial alignment through the plates II] and I I and the arms 30 and 3! are secured by pins in these apertures 32.

In operation the door 36, concealing the entire unit in the desk 20, is opened, and the board I9 supporting the typewriter 28, is pulled out. This Will slide the entire unit on the rails 21, to a stop 31, and cause the rollers 24 and 25 to rotate in the channels H and I4, respectively, causing the board I9 to raise upward in a horizontal plane, when the rollers 24 and 25 reach the horizontal channel l3, the board I9, with the typewriter 28 attached, may be drawn out still further to a position most convenient to the operator.

If a variation in height is desired, the operator can make the necessary adjustment by changing the pins or bolts in the apertures 3 or 32, in the plates It and II, depending on the type or design, to raise or lower the entire device.

The invention is susceptible of various changes in its form and minor details of construction, and the right is herein reserved to make such changes as properly fall within the scope of the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent in the United States, is:

1. The combination with a support, of a carriage on said support and having vertical side plates and horizontal cross members supporting the same, angular channelled rails fixedly mounted on the inner sideeof said vertical side plates,

i horizontally'disposed channel railsimounted for parallel movement by means of links on the outer sides of said vertical side p'late sfgu'ide rails fixedly rollers engaged. in the'channels of theangular 10 channelled rails to allow for. vertical and hori-' riage. 2. The

formed to provide inclinedportions'to allow! the vertical movements pf-;the mounting board and a, horizontal portion toallowior the hori-Q zontal movement of the mounting board when the latter is disposed in its elevated position. 7 V V 1 WILBERT 10 zontal movements thereof relative to" seid' V combination ias set forthjin claim I'wh'erein the' angular' channelled rails'are each 1
