DISPLAY OR ADVERTISING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 759,815, dated May 10, 1904.

Application filed November 18,1903. Serial No. 181,045. (No model.)

To (Ml whom it IH/(I/Z/ concern:

Be it known that I, E FRAIM LUNI )IN, a citizen of the United States, and a resident of Boston, in the county of Suffolk and State of Massa- 5 chusetts, have invented new and useful Improvements in Display or Advertising Apparatus, of which the following is a specification.

My invention relates to advertising or display aprmratuses, and particularly to that class wherein an apron bearing inscriptions, ad vertisements, or the like is moved step by step, so as to successively present the inscriptions or the like to view.

The object of my invention is mainly to pro- I vide an improved apparatus of the character indicated which will be entirely automatic in its operation; but my invention also has in view to provide an improved display or advertising apparatus wherein the, apron bear- 2 ing the inscriptions or the like will be automatically moved first in one direction step by step for a predetermined distance and then in the opposite direction step by step for a predetermined distance, when its direction of movement will be again reversed, so that as long as the apparatus is in operation the apron is automatically moved step by step first in' one direction and then stop by step in the opposite direction.

3 In accordance with my invention the apron is actuated by a driving-motor, which is controlled by a second motor. Means provided for automatically starting the driving-motor and stopping the controlling-motor after the latter has operated to a predetermined extent and for automatically stopping the driving motor and starting the controlling-motor after the driving-motor has operated to a predetermined extent. In this way each operation of 4 the driving-motor shifts the apron which bears the inscriptions or advertisements a definite distance, and each operation of the controlling--motor causes the apron to be held stationary for a definite interval of time, after which the driving-motor is again operated.

In the best form of my invention the driving-motor and the controlling-motor each has a separate circuit of its own, each of said circuits being controlled by a separate switch. hen the apparatus is in operation, the driv- 5o ing-motor acts to automatically open its own switch and close the switch of the controllingmotor after the apron has been shifted a step, and after the controlling-motor has operated for a predetermined length of time said controlling-motor acts to automatically open the switch of its own circuit and close the switch in the circuit of the driving-motor, thus causing the driving-motor to again move the apron a step. In this way the inscriptions on the apron are not only successively presented to view by the driving-motor, but during the interval of time taken up by the operation of the controlling'motor the apron is held stationary, so that the inscriptions or advertise- 5 ments can be inspected or readthat is to say, the motors are intermittently operated, so that when the driving-motor is operated the apron is moved a definite predetermined distance and when the controlling-motor is 7 operated the apron is held stationary for a predetermined length of time, and this is a distinguishing characteristic of the best form of my invention.

In the best form of my invention I also pro 7 5 vide a reversing-switch or pole-changer in the circuit of the driving-motor, which switch is automatically operated to reverse the driving motor when the apron has been moved step by step to a predetermined extent in either d irection.

In the accompanyingdrawings, Figure 1 is an elevation of a display or advertising apparatus embodying one form of my invention with the apron, hereinafterdescribed, omit- 5 ted for clearness. Fig. 2 is a side view showing the relative arrangement of the apronsupporting rolls. Fig. 3 is a plan View, on an enlarged scale, of the top portion of the apparatus shown in Fig. 1. Fig. I is an ele- 9 vation of the parts shown in Fig. 3. Fig. 5

is a diagram showing the main elements and the circuits of my improved display or advertising apparatus.

Having reference to the drawings, 1 represents the main framework of my improved other end is fastened.

apparatus, within which are journalod an upper apron-driving roll 2 and a lower drivingroll 3. Alongside driving-r0112 is journaled a presser-roll 4, and alongside driving-roll 3 is journaled a presser-roll 5. On frame 1 are also journaled two take- up rolls 6 and 7, and an apron 8 is fastened at one end to roll 6, from which it passes between rolls 2 and 4 and thence between rolls 3 and 5 to roll 7, to which its Upon this apron 8 and at suitable distances apart are inscribed the advertisements or the like which are to be displayed. Each roll 6 and 7 carries a pinion 9, connected, through an intermediate gear 10, with a largegear 11, to which one end of spring 12 isfastencd. The other end of each spring 12 is fastened to frame 1, and the spring 12 of roll 6 is opposed to the spring 12 of roll 7, so that when apron 8 is positively shifted toward roll 7, as hereinafter described, spring 12 of roll 6 is wound up and spring 12 of roll 7 unwinds, and thereby winds the apron onto roll 7 as it is moved toward said roll. hen apron 8 is shifted toward roll 6, as hereinafter described, spring 12 of roll 6 is allowed to unwind and spring 12 of roll 7 is wound up.

Each driving- roll 2 and 3 has fixed to it at one end thereof a worm-gear 13, and these two worm-gears 13 are driven each by a worm 14, fixed to a shaft 15, journaled on frame 1. Shaft 15 carries a pulley 16, connected by a belt 17 with a pulley 18, fixed to the armature-shaft of an apron-driving motor 19. At its upper end shaft 15 also carries a worm 20, which drives a worm-gear 21, (see Figs. 3 and 4,) fast to a shaft 22, journaled in bearings on frame 1. On this shaft 22 is mounted a worm 23, which when rotated in the direction indicated by the arrow drives segmental wormgear 24 in the direction indicated by the arrow on said gear-that is, the worm 23 turns gear 24 until the teeth of gear 24 clear said wormwhen aspring 25, connected at one end to a crank-pin 26 on gear 24 and at its other end to frame 1, gives a sudden partial rotary movement to gear 24 and moves said gear far enough to reengage its teeth with worm 23. When worm 23 is rotated in a direction opposite to the arrow on shaft 22, gear 24 is idle; but another gear, 27, which is also provided with a crank 28, connected to a spring 29, is operated in a similar manner. This gear 27, however, is idle when worm 23 is rotated in the direction indicated by the arrow on shaft 22.

Pivoted at 30 to frame 1 is a bell-crank switch-lever 31, one arm of which carries a contact 32, adapted to cooperate with a fixed contact 33, mounted on frame 1, and the other arm of lever 31 carries a contact 34, adapted to cooperate with a fixed contact 35, also mounted on frame 1.

The two segmental gears 24 and 27 are arranged alongside one of the arms of lever 31, and journaled on a stud 36, alongside the other arm of the lever 31, is a segmental gear 37, provided with a crank-pin 38, the latter being connected to one end of a spring 39, fastened at its other end to an arbor 40, journaled on frame 1.

The teeth of the segmental gear 37 are engaged by a gear 41, journaled on a stud on frame 1, and gear 41 is driven by a pinion 42, fast on arbor 40. Arbor also carries a gear 43, driven by a worm 44, fast on a shaft 45, journaled in bearings on frame 1. Shaft 45 carries a pulley 46, connected by a belt 47 with a pulley 48, fast on the armature-shaft of a motor 49, fixed to frame 1.

hen motor 49 is in operation, it acts through belt 47, pulley 46, shaft 45, worm 44, gear 43, arbor 40, pinion 42, and gear 41 to rotate gear 37; but part of each revolution of gear 37 is effected by gear 41, and they balance of each revolution is effected by the spring 39 that is, gear 41 turns gear 37 until the teeth of the latter are free from gear 41, and then by a quick movement spring 39 completes the revolution of gear 37 and re engages its teeth with gear 41.

Each time one of the gears 24 or 27 is moved by its spring 25 or 29 the crank 26 or 28, as the case may be, strikes the adjacent arm of the lever 31 and moves the latter in one direction, and each time gear 37 is moved by its spring 39 its crank-pin 38 strikes the adjacent arm of lever 31 and moves the latter back to its first position.

As shown in Fig. 5, contact 33 is connected by a wire 50 with a positive line-wire 51, and contact 32, which cooperates with contact 33, is connected by a wire 52 with motor 49, the latter being connected by a wire 53 with the negative line-wire 54, so that when motor 19 causes either crank 26 or 28 to strike and lever 31 contacts 32 and 33 areconnected, and the circuit of motor 49 is thereby closed. It will now be observed that when the motor has operated long enough to cause spring 39 to complete the revolution of gear 37, Which was begun by thus starting motor 49, crank-pin 38 will strike the adjacent arm of lever 31, and contacts 32 and 33 will be separated, thus stopping motor 49.

As shown in Fig. 5, contact 35 is connected by a wire 55 with line-wire 51, and contact 34 is connected by a wire 56 with one end of the winding of the field of motor 19. The other end of the winding of the field of motor 19 is connected by a wire 57 with a movable contact 58, the latter constituting part of a polechanger or reversing-switch 59. hen the motor is running in one direction, this contact 58 of the reversing-switch rests against a fixed contact 60, connected byawire 61 with one of the brushes of the commutator of motor 19. The other brush of the commutator of motor 19 is connected by a wire 62 with the other fixed contact, 63, of reversing-switch 59, and against contact 63 rests a movable contact 64,

connected by a wire with line-wire 54. It

will thus be seen that when the reversingswitch 59 is in the condition shown in the drawings motor 19 is driven in one direction, when contacts 34 and 35 are closed, and that its circuit is from line 51 through wire 55, contacts 34 and 35, wire 56, the field of the motor 19, wire 57, contacts 58 and 60, wire 61, the armature of motor 19, wire 62, contacts 63 and 64, and thence through wire 65 to line-wire 54. It will also be observed that when lever 31 is operated byeither of the cranks 26 or 28 the circuit of motor 19 is opened at 34 35 at the same time that the circuit of motor 49 is closed at 32 33; also that when lever 31 is operated. by crank-pin 38 the circuit of motor 19 is closed at 34 35 at the same time that the circuit of motor 49 is opened at 32 33.

The mechanism so far as described acts automatically to operate the motors 19 and 49 alternately and intermittently, and its operation is as follows: Starting with lever 31 in the position shown in Fig. 3 and with contacts 34 35 closed and contacts 32 33 open, motor 19 is in operation and continues to operate until worm 23 has rotated gear 24 far enough to clear the teeth of the latter from said worm, whereupon spring 25 completes the revolution of gear 24 and causes crank 26 to swing lever 31 on its pivot 30 far enough to disconnect contacts 32 33. This stops motor 19 and starts motor 49, which continues in operation until the teeth of gear 37 clear the teeth of gear 41, whereupon spring 39 completes the revolution of gear 37 and causes crank-pin 38 to strike lever 31 and return it to its first position, thereby stopping motor 49 and again starting motor 19. Thereafter the alternate and intermittent operations of the two motors are automatically repeated. Thus motor 19, which drives apron 8, automatically stops itself after shifting the apron to a predetermined extent, and after a predetermined interval of time said motor 19 is automatically started again by the motor 49.

The reversing-switch 59 comprises besides the contacts 58, 60, 63, and 64 two other movable contacts, 66 and 67, the contact 66 being connected by a wire 68 with wire 65 and contact 67 by a wire 69 with wire 57.

As shown in Figs. 3 and 4, the contacts of reversing-switch 59 are mounted on frame 1 alongside a forked lever 70, carrying a wedge 71. Lever 70 is moved in one direction bya spring 72, fast at one end to said lever and at its other end to frame 1 and in the opposite direction by a crank-pin 73, carried by a segmental gear 74. Crank-pin 73 has fastened to it one end of a spring 75, and the other end of said spring is fixed to frame 1. Gear 74 is engaged by a pinion 76 on arbor 77, which also carries a worm-gear 78, driven by a worm 79 on an arbor 80. Arbor 80 also carries a wornrgear 81, driven by a worm 82 on an arbor 83, on which is also mounted a wormgear 84, driven by the worm 44 on arbor 45. Each time motor 49 operates it acts through the mechanism just described to rotate gear 74 in the direction indicated by the arrow one step, and when motor 49 has operated a number of times--say, for example, twenty times-and gear 74 has moved a corresponding.number of steps pin 73 clears the forked lever 70, and spring 72 acts to swing lever 70 toward the contacts of reversing-switch .59 and to force wedge 71 in between contacts 66 and 67 of said switch, thereby carrying said contacts 66 and 67 against contacts 60 and 63 and contacts 58 and 64 away from corn tacts 60 and 63. Thus motor 19.is automatically reversed by motor 49 when the apron 8 has been shifted a predetermined number of steps in one direction. Motor 49, however, continues to operate as before, and crank-pin 73 continues to travel in the same direction as before motor 19 was reversed, and when motor 49 has again operated twenty times and gear 74 has been moved a corresponding number of steps the teeth of gear 74 clear the teeth of pinion 76 and spring 75 gives a quick partial rotary movement to gear 74 in the same direction it was traveling suiiieient to cause crank-pin 73 to engage lever 70 and return it to its first position, as shown in Fig. 3, and at the same time the teeth of gear 74 are reengaged with pinion 76. Thus motor 19 is again auton'latically reversed by motor 49 when the apron 8 has been shifted a predetermined nu mber of steps in the opposite direction. lontacts 58 and 64 each has mounted in its outer free end a screw 85, and these two screws 85 hear at their inner ends upon blocks of insulation 86, carried by the contacts 66 and 67. The s1'n-ing-contacts58, 66, 67, and 64 are adjusted or set so that when wedge 71 is out of engagement with contacts 66 and 67 contacts 58 and 64 are against contacts 60 and 63 and contacts 66 and 67 are held away from contacts 60 and 63 by the screws 85. When, however, wedge 71 is forced in between contacts 66 and 67 and the latter are carried against contacts 60 and 63, the movement imparted to them by the wedge acts through screws 85 to shift contacts 58 and 64 away from contacts 60 and 63. As will now be clear, my improved display or advertising apparatus is entirely automatic in its operation and acts to shift the apron bearing the inscriptions or advertisements step by step first in one direction for a predetermined distance and then stop by step in the reverse direction for a predetermined distance, also that the intervals of time taken up by the operations of motor 49 causes the apron to be held stationary long enough to permit the inscriptions or advertisements to be inspected or read.
