ing of a main frame superposed upon a suit abl'e'base', referably made in one piece and having a movable and! disposed therein, revolvable about a horizontal shaft disposed within the main column; akey stem asses through the upper column structure termi hating in a key its upper end and in a flexible lower stem upon the lower end thereof, adapted to contact with and rotate the movable arm about the horizontal shaft. A spring is disposed about the key stem and normally maintains the sal ne in raised position and a yoke and spring being disposed- "ut the movable arm adapted to actuate the same in either direction when the" same passes a predetermined position.

A further object of my invention consists in providing a portable table signaling device that is complete in itself and adapted foru se upon any table or location. I

With these and incidental objects in view, the invention consists in novel features of construction and combination of parts, the essential elementsof which are set forth in the appended claims, and a. preferred form of embodiment of which is hereinafter shown with reference to the'drawings which accompany and form a part of this specifie'ation.

In the drawings Fig. 1 is a side elevation of my assem bled device with the signaling arm shown in raised position.

Fig. 2 is aside elevation; partially in section of the mechanism shown in Fig. 1 the signaling arm being shown in its lowered: position and disposed within the .column,: and the key and key stem being in their normally raised position.

Fig; 3 is a side elevation,- partially in sec-- tion of the mechanism, showing the signaling arm inraisd position, with the key stem partially depressed in the act of lowering into positionyfor lowering the" signaling arm. w

Fig. .4 is-a fragmentary side elevation, partially in section illustrating th s gma/L ing arm being lowered through the action of the key stem with the lower end of the k8t6111 in its full loweredposition.

1g. 5 is a cross section View, taken on line 5-'15 of Fig. 2, looking in the direction indicated.- I

Fig. 6 is a fragmentary side elevation of the upper end of the signaling arm shown removed from the device with the yoke and spring in position.

Like reference characters refer to like parts throughout the several views.

1 is the body portion of the signaling device terminating on its lower end in the base the same being made of a shell like ier'mation and preferably having tapered side walls, a slit or longitudinal opening 3 being formed on one side of the same to permit the passage therethrough of the signaling arm 4. The signaling arm is journaled about a' horizontal shaft '5, which passes through the side wall of the column structure and is threaded therein. as shown at 6, the opposite end of which is seated within the hub 7 formed on the inside of the column structure. The upper end of the body portion terminates in a neck or reduced body portion 14, and has at the bottom a partition 9 disposed thereacross, which serves as a lower bearing for the key stem 10 which passes therethrough. The partition 9 also acts as a seat for the compression spring 11. The compression spring 11 passes about the key stem, as shown in Fig. '3 aiid which has the upper end thereof contacting with the stop pin 12. The object of the compression spring 11 is to" maintain the. key stem in the raised.

position. The key stem passes through a cap 13, which is disposed about the upper end of the neck 14 of the shaft of the column. Disposed upon theuppe-r end of the key new is a key top 15. The key stem 10 passes through the cap 13', and the diaphragm 9, thus "forming two bearings for the same which maintain the key stem in alignment and in position. Disposed upon the lower end of the key stem is. a flexible contacting rod 16, adapted for. engagement with the signaling arm to raise and lower the same. The normal position of the key stein is in raised position, as shown in Fig. 2, and the normal position of the signaling arinisin the lowered posit me a hown in Fig. 2, the same being disposed within the column structure and out of vision. A recess 17 is formed about the outer periphery of the signaling arm to form a path and a contacting surface for the lower end 16 of the key stem. An inclined surface 18 is formed upon the signaling arm against which the lower end l6 of the key stem contacts and is guided into the socket 19 disposed therein and as the key stem is further depressed it will rotate the signaling arm about the shaft 5. Also secured to the inner end of the signaling arm is a pin 20 upon which the yoke 21 oscillates and secured to the lower end of the yoke 21. is a tension spring 22, the lower end of which is secured to the column, as shown at 23. When the key stem has been suliiciently depressed the signaling arm is raised until the point is reached past center, and the tension spring will then raise the signaling arm to its full position as shown in Fig. 3 until the upper edge thereof contacts with the upper end of the slit 3 as shown at 23; the same will be maintained in this position through the action of tension spring 22. Upon the release of the hand of the actuator from the key top 15, the compression spring 11 will return the same to its normally raised position and in doing so will relieve the lower end 16 of the key stem from the slit and contact with the socket 19 and will be raised clear thereof. l/Vhen it is desired to lower the signalin arm from position as shown in Fig. 3, the key top 5 and the key stem is lowered by the hand of the operator until the same contacts with the inclined surface 24-, until the contacting rod reaches the socket 25, and the further depression of the key stem will lower the signaling arm sufiiciently until the pin 20 passes the center line of the support for the signaling arm at which time the tension spring 22 will return the signaling arm to the position as shown in Fig. 2.

It will thus be seen that I have provided a mechanism wherein the signaling arm may be raised. and lowered through the depression of the key stem with the hand of the operator thereof.

lV-hile the form of mechanism herein shown and described is admirably adapted to fulfill the objects primarily stated it is to be understood that it is not intended to confine the invention to the one form of embodiment herein shown and described, as it is susceptible of embodiment in various forms, all coming within the scope of the claims which follow:

What I claim is 1. In a vertical cone shaped hollow standard provided with a table signaling device, the combination of a longitudinal opening formed in said standard, an arm pivotally mounted within said body portion adjacent the upper end thereof, and adapted to an arrested rocking movement on said pivot, said arm being adapted to pass through said longitudinal opening in said standard and to normally rest therein; oppositely positioned and inwardly disposed notches formed on the inner end of said arm, the relative positions of said notches being changed from raised to lowered position or vice versa as said arm is rocked on its pivotal mounting; a sliding stem vertically mounted through the top of said standard and terminating in a contacting rod at its lower end and engageable with the notch in the upper position to move the same down to lower position, at the same time rocking the arm and raising the notch theretofore in lower position, to upper position subsequently engageable by said contacting rod and a yoke pivotally mounted to the arm adjacent its inner end at a point spaced between said notches, and adapted by means of a tension spring having one end secured to said yoke and the opposite end secured to the interior wall of the standard to maintain said arm stationary at the point of arrest of its rocking movement.

2. In a table signaling device, the combination of an upright body portion having an outwardly projecting base, there being a longitudinal opening formed in said body portion; an arm pivotally mounted within said body portion adjacent the upper end thereof, and adapted to having an arrested rocking movement imparted thereto; said arm being adapted to pass through said longitudinal opening and to normally rest in said body portion; oppositely positioned and inwardly disposed notches formed on the inner end of said arm; the relative positions of said notches being changed from raised to lowered position, or vice versa, as said arm is rocked on its pivotal mounting; a sliding stem vertically mounted through the top of said body portion, and terminating at its lower end in a contacting rod engageable with the notch in the upper position to move the. same down to lower position, at the same time rocking the arm and raising the notch theretoforein lower position, to upper position subsequently enga'geable by said contacting rod, a compression spring mounted about said stem and adapted to disengage said contacting rod of said notches; and a yoke pivotally mounted to said arm adjacent its inner end and at a point spaced between said-notohes and adapted by means of a tension spring, having one end secured to said yoke and the opposite end secured to the upright body portion to maintain said arm stationary at the point of arrest of its rocking movement.-
