ELECTRIC swrrcu-g.
SPEGIFIGATIOR forming part of Letters Patent No. 775,055, dated November 15, 1904. Applicationiiled March 25,1903. Benew ed September 7,1904. Serial No. 223,658. (No model.)
To all whom it may concern:
Be it known that I, IsAAo G. WATERMAN, a
citizen of the United States, residing at Santa Barbara, in the county of Santa Barbara and State of California, have invented certain new and useful Improvements in Electric Switches,
.of which the followingis a specification...
'provision, in connection with an electric switch, of an improved and novel indicator operated by the switch adapted to indicate which of the circuits controlled by the switch has previously been made.
I may say that the present switch, like the switch of my copending application before referred to, isfadapted especially for use in connection with either of the electromagnetic valves set forth in my copending applications filed March 9,-1903, Serial No. 146,975, and filed March 9, 1903, Serial No. 146,976, which are intended to be opened by a temporary current, then looked in open position, and finallyreleased'by another temporary current; The improvedindicator of the present switch is designed to indicate whether the valve is open or closed, and it is particularly designed for use when my electromagnetic valve is used to control hot-Water or steam radiators.
Another object of the invention is the provision of improvements on the push-button and contact-actuating pawl.
Another object of the invention is to provide a novel and improved switch having stationary contacts, a movable contact, and means for snapping or moving the movable contact int'o only momentary or temporary engagement with the stationary contacts,
whereby only a temporary or momentary cur-.
rent will be made.
A further object is to provide an improved switch adapted to alternately complete difierent circuits on alternate actuations of the switch. j
To accomplish the foregoing objects, 1 provide the novel and improved features and combinations of parts set forth in detail hereinafter and recited in the appended claims.
In the accompanying drawings, Figure 1 is a top plan view; Fig. 2, a verticalsection on line Y Y of Fig. 1; Fig. 3, a'detail view of the gearing and indicator; Fig. 4, a detail side elevation of the contact mechanism, showing the action diagrammatically.
The switch has a face-platel and inclosing shell 2 and a frame 3 for the different mechanisms, the latter being made from a single stamping. Secured to the frame 3 is a. tubular guide 4, having slots 5 in its sides. n insulating-block 6 is secured to the ends of the frame 3 and carries the common contact 7 and the two contacts 8 and 9. one contact, 8, being in the circuit of the valve-raising magnet, and the other contact, 9, in the circuitof the valve-locking magnet of the valve shown in either of my copending applications before referred to. The common contact 7 is for the return-wire of both circuits. J ournaled in the frame 3 is a square shaft 10, on which are secured a central ratchetwheel 11, insulating-strips 12 at the sides Serial No. 146,977.
Slidabl-e within the tubular guide 4 is a hollow push-button 16, having pins or screws 17 movable in the slots 5 and provided with a central stem '17, surrounded by a coil-spring 18, which bears against the end of the pushbutton and the end of the tubular guide 4 and keeps the push-button and parts movable therewith retracted. The stem 17 is extended beyond the end of the push-button, and in its bifurcated end is a pawl 19 on a pivot 20. This pawl has a tooth 21, positioned to engage the teeth of the ratchet-wheel by a spring 22. A spring-dog 23, having a roller 24 at its end, is adapted to engage and lock the ratchetwheel and contacts after being turned by the pawl 19.
On the shaft 10 is a gear 25, with which meshes a gear 26, which in turn meshes with a gear 27, fast with an indicator-wheel 28, a portion of whose periphery projects through a slot 29 in the face-plate l and bears the two words f On and Oif, so arranged that they will be displayed alternately. on succeeding movements of the push-button.
I have described a convenient form which the indicator may assume; but it will be understood that the same result could be accomplished in different ways, and 1 do not, therefore, limit myself to the foregoing construction. The indicator, it will be understood, shows the on and off positions of the valve with which the switch will be used and does not indicate thefact of the switch-contact disks being on or off their contacts. It can be readily understood. however, that the indicator could as well be used to indicate the fact of the movable contactbeing on or off its contacts.
When the push-button is pressed in, the tooth of the'pawl snaps into engagement with another tooth of the ratchet-wheel, and on the release of the push-button the spring 18 retracts the push-button, stem, and pawl and turns the ratchet-wheel and contacts with a snap action a quarter-revolution, causing the circuit to be made momentarily by reason of the temporary engagement of the projections on one of the disks (either 13 or 14) with the common contact 7 and either contact 8 or contact 9, as the case may be. The dog 23 looks the ratchet-wheel and contact-disks where turned. During the foregoing operation the gears turn the indicator and display the indicia thereon.
The essential idea of my invention being the provision of a switch having a movable contact and an actuating member cooperating with the movable contact to cause the latter to only momentarily or temporarily engage the circuit contact, other mechanism than what I have disclosed in this application can be employed to carry out my object, and I do not limit myself to the construction herein shown and described.
As the essential idea of the invention is the operation of the movable contact to first pass on and then off the circuit-contact as a complete action on any given single complete operation of the actu'atingmember, in the use of the words on each complete operation of the actuating member or language of similar import in the claims I have reference, in the broadest sense, to a complete cycle of movement of the actuating member on any given single actuation.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is a i 1. In an electric switch, the combination with a stationary contact, of a movable contact-arranged to only momentarily or temporarily engage the stationary contact when actuated, a spring-retracted actuating member,
