AUTOMATIC EXHIBITING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 393,898, dated December 4, 1888.

Application filed October 16 1888. Serial No. 288,245 (No model.)

To all whom it may concern:

Be it known that we, BERTRAND HAMBURG, PAUL KETTERER and EDUARD KETTERER, all subjects of the Emperor of Germany, residents at Frankfort on the Main, Germany, have invented new and useful Improvements in Automatic Exhibiting Apparatus, of which,

the following is a specification.

Our invention relates to devices for displaying watches, jewelry, and other articles; and its object is to provide an apparatus whereby such articles are automatically caused to pass before the eyes of the spectator intermittently, thus allowing a closer inspection thereof than is possible in apparatus wherein the articles pass continuously before the observer on trays or tables revolving on a vertical axis.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference designate corresponding parts in the several views.

Figure 1 is a sectional side elevation of a machine constructed in accordance with our invention. Fig. 2 is a plan view thereof, partly in section, on the line .90 a in Fig. 1. Fig. 3 is a broken front elevation thereof with the cover of the casing removed. detail side elevation of the locking and releasing mechanism for the tables; and Figs. 5', 6, and 7 are respectively a front elevation, a side elevation, and a partial plan view of a modified construction and arrangement of the lever mechanism for operating the tables.

The casing A, of any preferred dimensions,

has a suitable opening at its front through which the articles to be displayed therein may be seen, said articles being attached in any proper manner upon both sides of tables T, radially arranged in connection with each other upon a transverse shaft, Z, journaled in the extremities of upwardly and forwardly projecting brackets B, supported on the base of the casing. Upon the shaft Z, at the righthand side of said tables, is mounted a gearwheel, E, while at the left-hand side of said tables is mounted on said shaft a disk, F, provided with radial slots a in its periphery, three of such slots bein shown in the drawlhe gear-wheel E meshes with a gear-Wheel,

Fig. 4 is a I C, journaled below it on the adjacent bracket,

B, and having fixed to its shaft next its inner face a ratchet-wheel, D, adapted to be engaged by a pawl, K, pivoted upon a lever, H, and pressed upon by a spring, K thereon, which lever is pivoted at its outer end upon the shaft which carries the wheels C D, the inner end of said lever being bent horizontally at a right angle and normally drawn downward by a spring, G, attached, respectively, to said lever and the base of the cas ing, as shown in Figs. 1, 2, and 3 of the drawings.

A lever, L, fulcrumed at J on the bracket B at the left-hand side of the casing, having its outer end bent upward at a right angle and its inner end bent twice at right angles, as shown, respectively, in Figs. 4 and 2 of the drawings, is normally pressed upward by a flat spring, M, secured beneath it to said bracket B, so as to cause the outer bent end of said ley'er to enter one of the slots (L in the disk F, as shown in Fig. 4.

'lhe'apparatus is actuated by any suitable clock-work mechanism, U. A disk, S, mounted on a shaft constituting a part of said clockwork and adapted to be rotated in the direction of the arrow shown in Fig. 3, carries on its face a series of pins, N, four being shown in the drawings, which pins are adapted to engage the bent end of the lever Hand one member of a double-armed lever, Q, fulcrumed at V on the face of the plate P at the front of the clock-work U.

In operation, as the disk S rotates, the arm .of the lever Q adjacent thereto is pressed downward by one of the pins, N, causing the other arm of said lever to rise and lift the adjacent inner end of the lever L, thus disengaging the forward bent end of said lever from the disk F, as shown in dotted lines in Fig. 4E. Simultaneously with the disengagement of said disk the inner end of the lever H is raised by the engagement therewith of another of the pins on the disk S against the tension of the spring G, which spring, as the disk further rotates and said pin is disengaged from the lever H, exerts its tension and draws said lever downwardto its normal po sition. (Indicated in full lines in Fig. 1.) As

the lever is thus drawn down, the pawl K entables have made a third of a revolution, the 1 lever L, which hasin the meantime been again released from the disk I, as above described, is pressed upward by the spring )I, causing its bent end to slip into the next slot in the disk and arrest its motion and that ol the tables until the next succeeding pins on the f disk 8 again engage the levers Q and ll and cause the disk 1" to be released and the tables 5 l l t l l l l l to be rotated again,asabove described. These operations are repeated at regular intervals, according to the number of the pins on the disk .5 and their relation to each other, so as to successively display the articles on both sides of the tables.

In Figs. 5, t3, and 7 of the drawings we show a modified construction of the lever mechanism for effecting the intermittent rotation of the tables T. The disk S, which is mounted to rotate on a shaft connected with the clockwork 1', carries a series of pins, N, tive being shown in Fig. 5. The lever ll is fulcrumed to the plate P below and slightly at one side of the vertical center of the disk 5, and at one side of its fulcrum projects upward and then outward at a slight incline, and is connected by a cord, Y passing there from to and over a pulley, R, journaled on the plate I to a lever, ll'-, fulcrumed at O on the outer extremity of a projection, B of the bracket B, in which are journaled the shafts which carry the tables T and the gear-wheels and ratchet-wheels E U 1), respectively. Said lever ll at the other side of its fulcrum curves upwardly, and is then bent inwardly at a right angle partially over the face of the disk 5. The lever Q is fulcrumed at V on the plate P, but instead of being straight is slightly bent downward at. the left of. its t'ulcrum. The lever It carries a pawl, K, normally pressed by a spring, K, on said lever into engagement with the teeth of the ratchetwheel I), and the inner arm of said lever is connected by a spring, l, to the outer extremity of an upwardly and forwardly projecting arm, \Y, secured to the end of the plate I. The lever L, which engages with the slots in the disk I", has fixed to its inner end a weight, M.

In operation, as the disk t rotates in the direction of the arrow 1, (shown in 'lfiig. the levers II. and Q are engaged by the pins N adjacent thereto, one arm of the former lever being pressed downward in the direction of the arrow 1" and one arm of thelattcrleverin the direction of the arrowj. The depression of the arm of the lever Q, asabovc described, raises its other arm in the direction of the. arrowj', thereby raising the weighted end of the lever L and disengaging its other end from the lever ll is raised, and through its connection by the cord Y with the lever ll draws the latter lever downward against the tension of the spring G, whereupon the pawl K engages with a tooth oi. the ratchet-wheel l)and turns the same, which motion is transmitted by the gear-wheel t to the gear-wheel E on 1 the axis ot the tables T and turns them correspondingly, As the pins N pass and are idisengaged from the levers ll and Q, the

spring (l reacts to raise the lever ll-, its pawl rises and engages t he next toot h on the ratchetwheel l), and thelong arm of the lever Q t'alls, allowing the weighted end of the lever L to fall again and carry the other end of said lever into engagement, with the disk l and arrest the rotation of the tables until the succeeding pins on the disk S again operate on said levers Q and II, as above described, the range of rotation of the tables depending, as in the former construction and arrangtmlent, upon the number of pins in the disk 5" and their relation to each other.

Having thus fully described our invention, what we claim, and desire to secure by Letters Patent, is
