SPECIFICATION forming part of Letters Patent No. 726,250, dated April 28, 1903.

Application filed December 29, 1902. Serial N0.136,957. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM BRITAIN, Jr., manufacturer, a subject of the King of Great Britain, residing at Rocklea, Muswell Hill, in the county of Middlesex, England,-have invented a certain new and useful Improvement in Apparatus for Displaying Advertisements, of which the following is a specification.

According to this invention a disk or plate on which are advertisements is caused to revolve on pressure being applied to a table or platform. In the case of a table preferably the top of the table is made with some portions transparent, and the disk or plate revolves intermittently beneath it, moving first one and then another advertisement under the transparent portions. v

The table illustrated in the drawings is made in accordance with my invention.

Figure 1 is a section on the line 1 1, Fig. 2, and Fig. 2 is a plan with the table and disk removed. Fig. 3 is'a section to alarger scale on the line 3 3, Fig, 1, and Fig. 4: shows the controlling mechanism in another position. Fig. 5 shows another method of arranging the weights.

a. is the table, mounted on bars 19, carried at their inner ends by uprights 0, attached to a foot-step bearing d, on the under side of which is the piston d of a cylinder d filled with glycerin. 'On the outer ends of the bars I) are projections 19, sliding in guides 19 in the horizontal arms 6 on the main supports 6', the upward movement'of the table being limited by collars b on the projections b. The frame carrying the disk or plate f is su pported by a spindle f, free to turn in the foot-step bearing (1. A sleeve g, having a helical screw on its outside, surrounds the spindle f, and a crown-wheel g on the sleeve engages with a pin f on the spindle f. A tubular counterbalance-Weight h is free to move up and down on the main supports 6 and is attached to the ends of levers h, pivoted at k on the arms 6, the other ends engaging, by means of rollers 71 with the under side of the bars I), so that as the table is pressed down the weight h is raised. On the sleeve g and gearing with the helical screw thereon is another weightcz', carrying projections 'i, which engage with ward with it.

the weight h on its movement upward, causing the weight t to be also moved upward.

When pressure is put on the table, the under side of the bars b press down the ends of the levers h, causing the Weight h to rise and at the same time to carry the weight 2' up- If the pressure is removed from the table, the weight h descends, leaving the weight 'i behind. The weight 2' now descends, causing the sleeve g to turn, and as the crown-wheel g engages with the pin f the spindle f and the disk or platef on it are caused to revolve. The piston 11 of the cylinder d containing glycerin,prevents the movement of the table from being too rapid.

When it is desired to make the motion of the disk or plate intermittent, the mechanism described below may be used. On the under side of the frame carrying the disk f are projections f which engage in turn with a pin on a pivoted lever is, connected bya linklto another pivoted lever m. The lever 70 is at tached by a link n to one plate 0 of bellows, the weight of the plate being sufficient to draw the levers it and m into the position shown in Fig. 2. In the other'plate,p, of the bellows is a valve p.

q is a pivotedpawLwhic'h prevents any return motion of the disk.

When the lever It is turned by'the weight of the plate o,the projeotionf engaging with the pin it, is freed and the disk f allowed to turn. As it turns the next projection f engages with the lever m, closing the bellows, as is shown in Fig. 4, when the projection is freed from the lever m and engages with the pin it.

Fig. 5 shows a method of allowing the weight "i to be freed and descend, although the weight it does not descend. I In place of the projections t" pawls r are provided, which engage with the weight it until theyij are pushed out of connectionby fixed stops .3 allowing the weight 6 to descend.

The apparatus described illustrates one method of carrying out this invention, and I do not wish to be limited in any way to the details of the mechanism.

In the claims the word table is intended to include platforms and the like.

Whatl claim is 1. The combination of a table free to move vertically, a plate with a series of advertisements in operative relation therewith, and means whereby the plate is revolved by pressure on the table.

2. The combination of a table free to move vertically, a plate with a series of advertisements in operative relation therewith, means whereby said plate is moved by pressure on the table, and means for causing this motion to be intermittent.

3. A table, a counterbalanceweight attached to the table and capable of upward movement, a plate mounted on a spindle, and means whereby the spindle is revolved by the counterbalance-weight.

4. A table, a counterbalance weight attached to the table and capable of upward movement, a plate mounted on a spindle, a sleeve surrounding the spindle and in detachable connection therewith,and another weight capable of being moved upward by the counterbalance-weight, and means whereby the sleeve is revolved when the weight moves downward.

5. A table, a counterbalance weight attached to the table and capable of upward movement, a plate mounted on a spindle, a sleeve surrounding the'spindle and in detachable connection therewith,and another weight capable of being moved upward by the counterbalance-weight, means whereby the sleeve is revolved when the weight moves downward, and means for causing this motion to be intermittent.

6. A table, a counterbalance-weight attached to' the table and capable of upward movement, a plate mounted on a spindle, a sleeve surrounding the spindle and in detachable connection therewit-h,and another weight capable of being moved upward by the counterbalance-weight, means whereby the sleeve is revolved when the weight moves downward, an escapement engaging with the plate, and bellows for controlling the motion of the escapement.
