My invention relates to improvements in card display machines and consists in the combinations, constructions and arrangements hereinafter described and claimed.

An object of my invention is to provide a card display machine which is adapted to automatically raise the front card from a group of cards, to a vertical position, to hold it in this position for a predetermined length of time and then lower the card behind the pack of cards, this same operation being re peated for each card in the pack whlle the machine is operating.

A further object of my invention is to pro vide a device of the type described, which makes use of novel means for moving the pack of cards forwardly for creating a space behind the pack for the reception of the card being temporarily exposed.

A further object of my mvention is to provide a device of the type described which makes use of two sources of lights, one source vice;

Figure 2 is Figure 3 Figure 3 is a section along the line 33 of Figure 2;

Figure 4 is a section along the line 4- 1 of Figure 3;

Figure 5 is a View similar to Figure 2, but showing the moving parts in an altered position;

Figure 6 is a sectional View of a pusher rod;

a section along the line 22 of Figure 7 is a perspective View of an ad-' justable stop Figure 1 is a perspective view ofthe de Figure 8 is a wiring diagram of the device; and

Figure 9 is a sectional detail view showing one of the cards as being provided with a conductor strip.

In carrying out my invention I provide a casing 1, which is divided into two compartments 2 and 3, the compartment 2 housing the card lifting mechanism and the compartment 3 housing the cards.

I will first describe the compartment with the lifting mechanism which includes arms 5, see Figure 2, and which are pivoted to a shaft 6, the shaft in turn being carried by uprights 7 which form a part of a movable frame 8, see Figure 3. The arms 5 are adapted to be swung from the full line position shown in Figure 2 into the dotted line position during the initial movement of the ma chine. The arms in raising to this position will lift one of the cards 4 into vertically exposed position, as shown in Figure 2.

The manner of connecting the arms 5 to the front card 4 is shown in Figure 5. It

will be noted from this figure that the arms F carry bell-crank levers 9, which are pivoted to the arms at 10 and which are limited in their movement by a pin 11 riding in an arcuate slot 12 in the lovers 9. The bell-crank lovers 9 rest against hooks 13 carried by the free end of each arm 5. The hooks 13 are so fashioned as to enter an eyelet 14, see Figure 9, in the card 1. The hooks 13 of both arms will simultaneously enter the two eyelets in the front card. A swinging of the arms 5 will cause the hooks 13 to lift the card and will cause the end 15 of each bellcrank lever 9 to bear against the opposite face of the card, as clearly shown in Figure 5. In this way the card 4 is temporarily secured to the arms 5 and will be moved by the arms. It is obvious that if the pivot point 6 of the arms 5 shown in Figure 2 should re main in the same position throughout the entire swinging of the arms, the books 13 would describe an are as they are moved upwardly and would therefore tilt the card into the dotted line position 16, shown in Figure 5, However, I provide means for moving the carriage 8 from the position shown in Figure 2 into the position shown in Figure 5 and time this movement of the carriage with the swinging of the arms 5 so that the hooks 13 will rise vertically and will therefore hold the card 4 in a vertical position while it is being exposed. Of course, the compartment 3 is provided with an opening 17 in the top thereof for permitting the cards to be removed from the compartment.

1 will now describe the means for initially swinging the arms 5 upwardly and for moving the carriage 8 forwardly at the same time. The arms 5, as hereinbefore stated, are

connected to the shaft 6 and the shaft in turn carries an arm 18, upon the free end of which is mounted a roller 19 that rides upon a cam 20 fixed to a shaft 21, see Figure 2. Figure 2 also shows how the shaft 21 carries a-worm gear 22, which is in mesh with a worm 23 that is carried by a shaft 24, the latter carrying a worm gear 25 in mesh with the worm 26 carried by a shaft 27, which operatively connects to a motor shaft 28, see Figure 3. In this way the speed of the motor shaft 28 is reduced sufficiently to cause the shaft 21 to slowly rotate.

lVhen looking at Figures 2 and 5 it will be noted that the roller 19 rides over the surface of the cam 20 defined by numbers 30 and 31, while the arms 5 are being raised into the full line position shown in Figure 5. During this same time a cam 32 mounted upon the shaft 21 is engaging with a roller 33 carried by an arm 34, this arm being pivotally connected to the carriage 8 at 35 and having a roller 36 contacting with a stop 37. Figures 2 and 5 also show how the arm 34 will be swung from the position shown in Figure 2 into the position shown in Figure 5 as the arms 5 are swung fronii the full line position shown in Figure 2 into the full line position shown in Figure 5. During this movement the cam 32 will have traveled a distance to cause the roller 33 to move from a point 38 on the cam to a point 39. It will be noted that the carriage 8 is moved forwardly by a spring 40 and that the cam 32 merely determines the speed and the limit of travel of the carriage 8.

After the arms 5 have been raised into the full line .position shown in Figure 5, the arms will remain in this position for a predetermined period of time, while the roller 19 controlling the movement of .the arms 5 moves from the point 31 on the cam 20 to a point approximately at 41, and the :roller 33 moves from a point 39 on the cam 32 (to a point 42. The speed of the shaft 21 may be :such as to cause any predetermined time limit to expire while the rollers .are moving between the points above referred to, thus holding the card 4 in display position for therequired time period. v

Further movement .of the came 20 and 82 will nowxcause the arm 34 to move the carriage 8 back into the full line position shown in Figure 2, whereupon the arms 5 will be carried back into dotted line position 43, shown in Figure 5. This, of course, causes the card 4 to tilt at the angle shown by the dotted lines 16 in Figure 5. lVhile the arms 5 have moved into the positions 43, the roller 19 will be riding from the point 41 on the cam 20 to a point 44, see Figure 5. At this juncture the roller 19 will strike a high point 45 in the cam 20, which will. raise the arms 5 from the dotted line positions 43 into the dotted line positions 46. This will raise the hooks 13 high enough to free the lower edge of the card 4 from the pack of cards. The card 4 will now swing by gravity into the dotted line position 47, shown in Figure '5.

It will now be observed that cam 20 has a portion 48 which will permit the roller 1.9 to rapidly move and to lower the arms 5 into the full line position shown in Figure 2. During this movement the lower edge of the card 4 will ride over strips 49 past rollers 50 carried by the strips and down in back of the pack of cards 4. During this movement of the arms 5, the portions 51 of the bellcrank levers 9 will .contact with idlers 52 carried by the carriage 8 and will cause the bell-crank levers to swing so as to release the hooks 13 from the eyelets 14. This, of course, frees the card 4 from the arms 5 and permits the card to drop in back of the pack while the arms 5 carry the hooks 13 to the front of the pack of cards for engaging with the next successive card.

The special construction of the strips 49 is shown in Figures 3 and 5 and it will be noted that the strips are secured to brackets 53 by screws 54 in such a manner that the screws 54 may be adjusted for varying the tension of the rollers 50 upon the back of the pack of cards.

At this point it will be well to notice the construction of the pack moving mechanis n which automatically makes room for the e posed card by moving the pack of cards for wardly as soon as the front card is removed. this operation being repeated so long as the machine operates.

A rod 55, see Figure 5, is pivotally carried by a bell-crank lever 56'and by an arm 57. There are two of these rods provided, one being disposed at each side of the machine and there are also two arms 57 provided for supporting the rods. One bell-crank lever supports one rod while an arm 56 supports the other. Each rod 55 carries a springpressed plunger 58, see Figure 6, and this plunger is limited in its movement by a set screw 59 slida'ble in a slot 60. The bell-crank lever 56 and the arm 56 are carried by uprights 61', which in turn are secured to lugs 62, see Figures 3 and 5, which are carried by the base 63. A shaft 57 operatively connects the lever 56 with the arm 56. Figure 3 shows how the base 63 is provided with tracks 64 for the reception of rollers 65,

which carry the carriage 8. The carriage 8 is further provided with tongues 66 which ride in guide channels 67 and which are retained in place by cover plates 68.

The bell-crank lever 56 carries a roller 69 which is adapted to be contacted by a cam 70 carried by the shaft 21 when the cam is moved into operative relation with the roller 69 by the carriage 8. The cam 70 is so positioned on the shaft 21 as to actuate the bell-crank lever 56, rods 55 and spring plungers, 58 when a card 4 is being swung from the dotted line position 16 into the dotted line position 47 see Figure 5. During this movement of the rods 55, the arms 57 will be swung to the right when looking at Figure 5 and will rock bellcrank levers 71 about pivots 72 for moving card pushers 7 3 away from the pack of cards. The bell-crank levers 71 are connected to the arms 57 by links 74 and the bell-crank levers may be adjusted by adjusting an arm 7 5 at the desired position and then tightening a nut 76, see Figure 5. Each arm 57 is carried by an upright 7 7 which in turn is secured to the base 63 and the arm may be limited in its movement in a counter-clockwise direction when looking at Figure 5, by means of a stop member 78 of the shape shown in Figure 7. The stop member 78 is pivotally mounted on the pivot point 7 9 of the arm 57 and is secured in adjusted position by a lock bolt 80. The bolt 80 passes through a slot 81 in the stop member 78, see Figure 7, and in this way the stop lug 82 may be positioned with respect to the arm 57 for limiting the movement of the arm.

The operation of this portion of the device is such as to cause the spring plungers 58 to contact with the pack of cards while the card pushers 78 are moved away from the pack of cards and then to move the spring plungers away from the cards while the pushers 78 contact with the cards. The movement of the plungers and the pushers is quick and one follows in rapid succession to the other so that as the card 4 is moved down in back of the thickness of one card, prior to the time of the exposed card dropping down into its lowermost position, yet subsequent to the time the exposed card passes the spring plungers 58. A coil spring 83 urges the arms 57 in a counter-clockwise direction.

I will now describe how the cards are iltransparent cards 86 carries a metallic strip 87 which closes contacts 88 and 89, which are disposed as shown in Figure 9, so as to be engaged when the card 86 is in raised position. The current will now flow from line 90 through wire 91 magnet 92, wire 98, terminal 89, strip 87, channel 88, light and wire 94. This energizes the light 85 and causes the magnet 92 to break the switch 95 which cuts off the circuit to the light 84.

When, however, a non-transparent card is raised into exposed position, the current for light 85 will be broken between terminals 88 and 89 and will thus de-energize magnet 92, thus permitting a spring 96 to close the switch 95 and cause the current to flow from wire to wire 97, switch 95, wire 98, brush 99, commutator 100, brush 101, Wire 102, light 84, wire 108, and back to wire 94. The commutator carries a conductor strip 104 which closes the circuit to the light 84. The commutator 100 is carried by the shaft 21 and is therefore timed so as to energize the light 84 when the card 4 is in the position shown in Figure 1. f the card happens to be a transparent one, as shown in Figure 1, the light 84 is extinguished, and the light 85 is energized in the manner just described.

In Figure 1 I show an electric cord 105 leading from a source of current to the ma chine and a circuit through this cord being controlled by a switch 106. Figures 3 and 4 show how the wires 105 lead to brushes 107 which ride upon strips 108. Wires 109 lead from the strips 108 to the motor 110. In this way the circuit is kept closed to the motor while the carriage 8 reciprocates as soon as the switch 106 is closed.

The member 58 moves the cards forwardly to cause the front card to be impinged upon the hooks 13. The lever 71 moves the bottom of the cards forwardly to prevent the cards from bunching at the back of the pack.

Although I have shown and described one embodiment of my invention, it is to be understood that the same is susceptible of various changes and I reserve the right to employ such changes as may come within the scope of the appended claims.
