therebyto the attention of the user of the table.

With this object in view the invention consists in the novel construction and combinations of parts, which will be hereinafter fully described and claimed, I

In the drawings, Figure 1 is a perspective view of my im roved table. Fig. 2 is a vertical section t ough one end of the table, showing the supporting-legs partly broken away. I v

The table com rises a casing l and the supporting-legs 2t erefor. The casingis provided with oppositely-inclined hinged doors 3, which form the top of the table and by means of which access may be readily had to the interior of the casing. Each door com,

prises a frame 4, inclosing a panel of glass 5 or-other transparent material.

Arranged longitudinally of the table are three parallel rollers 6, 7, and 8. The two rollers 6 and 7 are arranged side by side and centrally within the casing 1, and the roller 8 is arranged centrally of the table and a slight distance above the top thereof, the rollers 6 and 7, being journaled in the endwalls of the casing and the roller Sbeing journaledin suitable standards 0 Suitably arranged Within the casing 1 is an electric motor 10, the shaft of which is provided with a worm 11in engagement with a worm-wheel-12 on a stud-shaft 13, journaled in the casing. This shaft 13 is provided with a pinion 14, in meshwith a ear-wheel 15 on a stud-shaft 16, and the stu -shaft-16 is progear-w I vided with a pinion 17, in mesh with a gearwheel 18' on the shaft of the roller 7. The gear-wheel 18is in mesh with a similar wheel 19 on the shaft of the roller 6, to the end that when the motor 10 is actuated the rollersfi' and 7 will be slowly rotated in opposite directions toeach other by the gearing just described.

The shaft of the roller 6 is provided with a bevel gear-wheel 20, which coacts with a similar wheel 21 on the lower end of aninclined shaft 22, which extends through the top of the casing and is journaled in a bearing 23, see cured to the adjacentstandard 9. The uper end of the shaft 22 is rovidedwith a evel' ear-wheel 24, in mes with a similar lreel 25 on the shaft of the roller 8, whereby when the rollers 6 and 7 are slowly rotatied the roller 8 will also be slowly rotate i Each door 3 3- rests normally upon a spring 26 located withinthe casing 1, the distance between the bottom of each door and the top of the casing being such as to permit a slight depression of the door against the action of 1 the spring. Secured to the frame 4 of each door 3 is a contact-plate 27, and secured to the bottom of the casing directly beneath each plate 27 is another contact-plate 28. The plates 27 27 are connected with one brush of the motor 10 by wires 29 30,-and the plates 28 28 are connected to an electric battery 31 by wires 32 33, and the battery is connected to the other brush of the motor 10 by a'wire 34.

When the doors 3 3 are in their raised or normal'positions, the contact- plates 27 and 28 are out of contact with each other, and the electric circuit is broken, and when either door 3 3 is de ressed against the action of its spring 26 b t e Wei htof the arm of the per-. son using t e desk t e contact-plate 27 will be moved into engagement with the plate 28,

thereby completing the electric circuit and starting the operatlon of the motor 10, which through the mechanism hereinbefore de-- scribed will slowly rotate the rollers 6, 7, and
