ELECTRIC SWITCH.
Specification of Letters Patent. Patented Dec. 24, 1912.
Application filed- J'anuary 3,1912. Serial No. 669,163.
To all whom it may concern! Be it known that I, JOHN VVoon, a
citizen of the United States of America, re-'- as used in connection with theignition de vices for internal combustion engines, as for example, two different sets of batteries, either primary or storage; or a battery and magneto may be connected.
to provide means to securely lock the switch- The particular object of this invention is lever against operation when not in use; and, second, to permit the switch-lever to readily operate from one position to another.
In general, "the invention consists of a base-piece of suitable insulating material having contact members mounted thereon, a
switch-lever adapted to form a contact with said members, and means for locking the lever against operation when not in use'but permitting the lever to be readily unlocked when the switch is to be-used to make the proper electrical connections to the ignition devices. 1
In the drawings forming part of this ap-- I Relferring to the 'drawings in detail, a
csignates the base member of the switch; 6
i the cap member secured thereto by any suitable means,as screws, which enter threaded sockets 0 in the base member.
d, e, and f designate Contact members to w ich the terminals from the sources of electrical energy are connected.
h is a switch-lever pivoted to the base -member a by means of the p vot construction '5. The inner end of the switch-lever plate 0,'the inner end of which moves over the ontact members. The switch-lever 72. is provided with an operating handle or knob 79.
The locking device proper comprises a struck-up portion or projection q. Located above this projection is a rotative barrel -member 1" having a groove 8 cut in its lower portion, which groove is for'the purpose of receiving the projection g and is of such shape that the barrel -member 1' may be turned about the projection by means of the key 7 either to lock the switch-lever it against movement, as shown in Fig. 1, or
permit the projection g .to pass freely through this groove, as shown in Figs. 2'
and 4. The key if and the thimble u are so constructed that the key canbe removed only when the switch-lever h is in a locked position, as shown in Figs. 1 and 3. A plate w is'mounted for rotation in the thimble u and is provided with a slit therein to permit the key to be inserted as in the well known Yale lock construction. The wings a: on
.the key I? prevent its removal when the 'thimbleu is inthe position shown in Figs.
1 and 4, as they are then under the projections y.
It will be noticed that the projection g and the center portion of the groove 8 is of Such shape that the barrel member r can be turned from theposition shown in Fig. 1
to that shown in Fig. 2; that is to say, the
center portion of the groove 5 is slightly concave, as shown at 3. When the groove 8 in the barrel member 1" is in the position shown in Figs. 2 and 4, the p ojection 9 simply passes through the groove permitting the lever to be swung from right to left and vice versa. Figs. 1 and 3 show the barrel 1 turned so that the groove 8 stands transverse to the projection q. The lever is then looked and the key maybe removed and the switch left, without any danger of itsbeing moved. I
The pivot pin 2', it will be noticed, has an extension piece 2' attached\ theretofand threaded on. this piece are nuts 2' to hold the switch lever in place, which are turned 1' whereby the lever may be retained in a down onto the elastic plate 0, as shown. A projection h on the end of the lever h enters a slit 0 of the elastic member 0.
The switch is shown with the letters B M and the word Oil to designate the three positions of the switch lever h, as being connected with the battery, magneto, or oft positions of the lever.
hat i claim, is zv L131 :1 switch, the combination with a lever, of a grooved barrel device, said lever having a projection thereon which enters the grooved part of the barrel, and means to operate the barrel device to change its position with relation to the projection.
A. switch comprising a base and cap member, contact members, a contact-lever,
' means to retain the lever in an inoperative u position,
said means includin a member movable with the lever that 15 above the plane of the same, an open-ended grooved device to receive said means, and a key device to operate said device to permit the lever to operate or to retain the same in an inoperative position.
3. In a switch, the combination with the contact-lever thereof, a rotative member having a recess therein, an element on the lever adapted to enter the recess, a key device ter operating the rotative member locked or unlocked position.
4. In a switch, the combination of a switch lever, 21 base member, a cap, a rotative member in the cap, and inter-engaging devices between the lever and the rotative member to ermit the lever to swing in the arc of a circle, or to be retained against movement.
5. In a switch, the combination with the switch-lever, of a cap member, a barrel member mounted in the cap member and having a groove in the lower portion, an element on said lever to enter the groove, :1 key device to operate the barrel member, means inter-engaging on said key and barrel to prevent the removal of. the key device except when the lever is in a lockedposition. v
6. In a switch, the combination with a switch lever, a rotatable member, an element carried by said switch lever and adapted to'engage said member, a,keydevice to operate the member to permit the element to pass freely through the member-when the
