Abstract: 27,256. Bloch, P., and AndrÚ, E. Dec. 10 Advertising; displaying.-Consists of an electrically-driven apparatus, which may be luminous or non-luminous as desired, for exhibiting inscriptions, advertisements, drawings, or photographs upon a moving band of insulating-material, such as cloth, paper, or the like, which may be transparent or not, the band being moved intermittently or continuously as preferred, and automatically reversed when it has reached the end of its travel in either direction. An elevation of the apparatus is shown in Fig. 1, and a diagrammatic view of the electrical connections of the mechanism, showing its working, in Fig. 3. A solenoid core x is first placed, say, in the position a, Fig. 3, so that a current passes through a coil b<1> of the solenoid S, and the copper piece w on the core x makes contact between blades h, h<1>. When the driving-motor M is in operation, continuously rotating a shaft A by means of a worm v and pinion e, the current that passes through a contact q on the armature a<E> of an electromagnet E, and through the contacts h<1>, h, traverses the windings of a bobbin B<1> and an electromagnet F, causing the armature a<F> of the latter to be attracted, thereby rotating a shaft A<3> and lifting brake shoes s, fixed on this shaft, off the bobbin B<1>. A soft-iron piece D<1>, which is capable of sliding a small amount along the shaft A, but rotates with it on account of a pin in the shaft engaging in a slot on the collar of the piece, is attracted by the electromagnet B', causing this bobbin to rotate along with its shaft A', on account of a slight friction between the bobbin and the iron piece D'. A toothed wheel N<1> on the shaft A<1> drives a roller R', which consists of a copper tube mounted by a collar c upon its axis, and insulated therefrom by a washer i, and thus winds up the advertising sheet O<1> which passes over auxiliary copper rollers R<3>, R', and at the same time unwinds the cloth from a roller R<2>, the electromagnetic bobbin B<2> of which, although not in magnetic connection, is free from its brake shoe s. When the advertisement to be exhibited arrives in the centre of the frame, an opening o<2> in the insulating-cloth comes underneath a metallic friction device f, and so makes contact with the roller R<3>, which is permanently connected with the source of electricity by a contact f<1>. The current consequently passes into the electromagnet E, causing it, by the movement of the armature a<E>, to interrupt the circuit of the bobbin B' and of the electromagnet F at q. The bobbin B' and soft-iron piece D' are no longer magnetically engaged, and the brake shoes s are caused to engage the bobbins B<1>, B<2> by means of springs on arms y, preventing further motion of the cloth. A switch C is so constructed that a copper plate d, fixed upon an insulated copper drum m driven by a toothed wheel j, and connected to the source of electricity by a rubbing contactpiece, passes during its rotation in succession over contacts k<2>, k<3> of lamps L, L, causing them to illuminate the advertisement successively as a transparency. The last lamp is extinguished as the plate d leaves the contact k<3>. The contact k<1> is short, and is permanently connected with the circuit of the bobbins B', B', but its duration of contact is sufficient to cause the bobbin B<1> to be engaged and the brake shoe s to be raised, the cloth being thereby moved, bringing the opening O<2> clear of the contact f. This interrupts the circuit of the electromagnet E, causing its armature a<E> to be raised by a spring z, and closes the circuit of the bobbin B' at the contact q, enabling current to be supplied by the plate d of the switch C until a fresh opening in the cloth comes underneath the contact-piece f and causes the circuit to be interrupted at q and the cloth to be stopped. When all the cloth has been wound on the roller R<1> in this way and completely unwound from the roller R', an opening o<3>, at a different level from the opening o<2>, comes underneath a contact-piece f<1>, and, as this touches the roller R', a current is sent through the bobbin b<2> of the solenoid S, bringing the rod x in the #-position, Fig. 3. The bobbin B' now passes through the same cycle of phenomena as the bobbin B<1> did, thus winding up the cloth on the roller R'. As the opening o<3> moves away from the contact f<1>, the current is interrupted in the bobbin b<3>, but the core x retains the #-position until the cloth is completely unwound from the roller R', when the combined action of a contact f<1>, and an opening similar to o<3>, but formed symmetrically at the other end of the cloth, brings the rod x into the alpha-position, again reversing the motion of the cloth. The movement of the motor may be transmitted, if desired, by toothed wheels, levers, cranks, belt, or chain, while the shafts A<2>, A<3> may cause the rotation of the rollers by means of conical gearing, lantern-wheel gearing, or belt or chain. The contacts f, f, &c., may be formed of conical, cylindrical, or spherical rollers, each adapted to rotate on an axle formed by a screw joining the two arms of a copper yoke or shoe, the whole being carried by a spring blade. The magnetic clutch B<1> D<1>, B' D<2> may be modified as follows:-The shaft A carries cylindrical pieces X, notched at the free surface V, and adapted to engage with notched pieces Y on the shafts A', A<2>, these pieces rotating with their shaft but also sliding thereon. An electromagnet H, acting similarly to the electromagnetic bobbins B<1>, B<2>, cause the engagement of the pieces X, Y when it attracts its armature ; on breaking the electric circuit a spring U causes their disengagement. The number and arrangement of the lamps, and consequently the number of contacts k<2>, k<3>, ... &c. of the switch C, may be modified as desired, and the lamps may be in front of the sheet for direct illumination. The number, height, and position of the rollers may be varied, as, for instance, by forming a polygonal lantern by placing rollers at the corners of a polygon, the advertisements being displayed on the face. The electrical connections may be such as cause continuous or intermittent motion of the cloth in both directions, or continuous motion in one direction and intermittent in the other. The openings o', o<3> may be of any desired size, and provided on each side of the cloth with metallic paper, glued or otherwise fixed, or with eyelets or metallic or non-metallic furnishings. The openings may consist of interstices between consecutive panels forming the sheet, or be made by cuttings in it, according as the cloth consists of panels or a single sheet. The panels are joined by folding back and glueing down the edges of the strips, cutting notches in adjacent strips so that they fit into each other, as shown at z, Fig. 1, and passing a strip of paper or other flexibe material down the continuous opening, forming a hinge that can easily be disconnected. An ordinary switch O has one terminal in common connection with all the electric circuits and its other with the lamps alone, so that they may be extinguished, if desired, without interrupting the working of the apparatus. 27,290. Taylor, J., and Taylor, J. B. Dee. 11. Displaying. -- Consists of a stand provided with removable trays, for exhibiting articles for sale and for like purposes, the parts of the stand portion being preferably made separable. The sides A of the frame are joined at the bottom by means of a cross-bar B and cross-pins B', and at the top by a suitable cross-head C prepared with keyhole slots D on its underside, into which fit screws E, on the top of the side pieces. A series of pins F<1>, F' in the side pieces hold the trays G, which are preferably shallow. The trays project a considerable distance in front, and the weight of this part causes the back portion to be pressed up against the pins F<2>, a fixing H, preferably of metal with plain or undercut recesses, being attached to each side of the tray to engage with the side pins F<2>, and to prevent the tray from slipping.
