INDICATING PUSH-IBUTTON.

Specification of Letters Patent.

Patented Mar. 26, 1912.

Application filed August 1, 1911. Serial No. 641,762.

To all whom it may concern Be it known that I, WVALTER R. SOHLAGE, citizen of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Indicating Push-Buttons, of which the following is a specification.

This invention relates to an indicating push-button.

It is the object of this invention to provide a push-button, which is so constructed and arranged that it may be employed as an indicator, and which is particularly adapted for use in operating electrical bells in offices, residences, and the like, for indicating to the operator whether the inmates are in or out.

A further object is to provide a simple means for setting the device to expose either of the indicating characters in and out or other marks for denoting whether the person called is present or absent.

Another object is to provide a device of the above character, which is simple in construction and operation and which can be manufactured and installed at small cost.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which Figure 1 is a vertical section of the invention partly in elevation. Fig. 2 is a plan View of'same. Fig. 3 is an inverted plan view, showing the adjusting device. Fig. 4 is a section on the line XX of Fig. 1. Fig. 5 is a'plan view, showing the push-button as c leprpssed to expose the indicating character In the drawings, A represents a cylindrical casing formed on an escutcheon plate 2, and which is adapted to be mounted on a door casing 3, or the like. Mounted within the casing A is a cylindrical block 4, of approximately the same diameter as the casing, and which block is preferably formed of wood or other insulating material.

Formed on the block 4 is a push-button 5,

formed in the outer end of the casing A, and by means of which the block 4 may be moved inwardly'in the casing A in opposition to a spiral spring 6 which is disposed in the easing and is tensioned to bear between the block 4 and an insulating plug 7, rigidly mounted in the open end of the casing A, as shown in Fig. 1; the spring 6 normally retaining the block 4 and push-button in their outermost position.

Mounted in the plug 7, and extending therethrough, are electrical conductors 8, the inner ends of which are bent outwardly and form contact members, which are adapted to be electrically connected by means of a contact plate 9 mounted on the block 4, when the latter is moved into its innermost position, by means of the push-button 5. The block 7 forms an abutment to limit the forward movement of the block 4. The outer ends of the conductors 8 connect with binding posts 10 on the plug 7, to which are attached the'terminals of positive and negative electrical conductors 11 and 11 leading from any suitable source of electrical supply and connecting with any desired electrical alarm bell in the usual manner, not necessary to be here shown.

Formed in the upper face of the cylinder A is an elongated slot 12 which extends circumferentially of the casing and is so disposed as to expose a portion of the surface of the block 4 adjacent to its inner end, as shown in Fig. 1. Formed on the concealed portion of the block 4, adjacent the slot 12, are the indicator characters In which are designed to be exposed in the slot 12 when the block 4 and push-button 5 are in their innermost position, as shown in Fig. 5,. and in which position the contacts 8 are closed to sound the alarm actuated through the conductors 11 and 11; the word In serving to denote that the person called is present. Formed on the block 4 peripheral in alinement with the indicating word In is the word Out which is disposed to one side of the slot 12 and normally concealed. When it is desired to expose the word Out in the slot 12 instead of the word In the block 4 is rotated a partial revolution so as to dispose the word Out in the position previously occupied by the word In. This rotation of the block 4 is accomplished by means of a pin 13 in the block 4, which extends through a peculiarly shaped slot formed on the underside of the casing A, as shown in Figs. 3 and 4. The above mentioned slot is formed with a peripherally extending portion 14 which terminates at each end in transverse slots 15--15, arranged at right angles to the peripheral slot 14, and which join with the portion 14 intermediate their ends. The pin 13 travels in the slot 15 when the bottom 5 and block 4 are moved inwardly to expose the word In in the slot 12, and travels in the slot 15 when the block 4 moves forward to expose the word Out the pin 13 being moved back and forth through the peripheral slot 14 between the slots 1515 to rotate the block 4 to dispose either the In or Out characters in position to be exposed in the slot 12.

The block 4 is designed to be set by the person called to indicate to the caller whether he is in or out, this information being imparted to the caller through the slot 12 when the push-button 5 is pressed. It is obvious, however, that the characters In and Out may be arranged on the periphery of the block 4 so as to register with the slot 12 when the block is in its outermost posi-' tion so as to constantly expose the characters. In setting the block 4 it is necessary to slightly depress the butt-on 5 to bring the pin 13 into alinement with the slot 14 before the block can be turned; the pin 13 being normally engaged in the outer end of either the slot 15 or 15 to prevent the block 4 being accidentally turned when the push-button 5 is in its normal outermost position.

While I have shown the invention as applied to a push-button for operating electrical contacts to sound an alarm, it is ob vious that other alarm mechanisms may be actuated by the depression of the button, or that the button may be used separate from alarm devices. It is also manifest that other indicating characters than those described may be employed if desired.

Having thus described my invention what I claim and desire to secure by Letters Patent, is

1. A push button having a combined longitudinal and angular movement,a guide casing in which said push button is reciprocally and turnably mounted, said casing having a slot formed in its side and said push button having characters adapted to be exposed through said slot, and means for adjusting the push button angularly to expose differ- Oopies of this patent may be obtained for ent characters in said slot when the push button is moved longitudinally.

2. A push'button, an indicator carried by the push-button, a guide casing in which said indicator is reciprocally mounted, a slot formed in said casing, indicating characters formed on the indicator and adapted to be exposed through said slot, and means for adjusting the indicator to expose differ ent characters in said slot, said means consisting of a pin on the indicator extending through a slot formed in the casing.

3. A push-button, an indicator carried by the pushbutton, a guide casing in which said indicator is reciprocally mounted, a slot formed in said casing, indicating characters formed on the indicator and adapted to be exposed through said slot, and means for adjusting the indicator to expose different characters in said slot, said means con sisting of a pin on the indicator extending through a slot formed in the casing, said slot arranged to admit of reciprocal movement of the pin lengthwise of the casing and also peripherally thereof.

4. A push-button, an indicator carried by the push-button, a guide casing in which said indicator is reciprocally mounted, a slot formed in said casing, indicating characters formed on the indicator and adapted to be exposed through said slot, means for adjusting the indicator to expose different characters in saidslot, said means consistin of a pin on the indicator extending through a slot formed in the casing, said slot arranged to admit of reciprocal movement of the pin lengthwise of the casing and also peripherally thereof, and means operable by said indicator for completing an electrical circuit.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
