Description

6, 1931. B. L. BOBROFF SWITCH FOR SIGNALING SYSTEIS I, gwoentoo d omaff @obrcff Patented Oct. 6 1931 PATENT OFFICE BORNETT' I1. BOBROFF, OF RACINE, WISCONSIN I SWITCH FOR SIGNALING SYSTEMS Application filed July 18, 1929. Serial No. 379,144.

This invention relates to switches and is particularly directed to switches for signaling systems, such, forinstance, as shown in my copending application for signaling systerms for automotive vehicles, Serial Number 377,821, filed July 12, 1929.

" In driving automobiles, aeroplanes or other automotive vehicles, if the driver has to select one of a plurality of buttons or switches in order to give the desired indication, his attention is needlessly distracted and he has to temporarily look away from the line of travel to select the proper push button or switch.

7 This invention is designed to overcome the defects noted above and objects of this invention are to provide a signaling switch in which a single universally mounted member is provided which may be moved in any direction desired corresponding to the intended 2o direction of travel of thevehicle, which 7 adapted to seleoti vely control any one of a.

: plurality (of "-jd i'tf'erent signaling circuits,

' which' does not requireiany thought on the:

part of the operator'as hefis merely required to move-the lever or handle in the direction 1 which the vehicle is intended'to go.

Further objects are tojprovide a signaling switch of extreme simplicity, which is easy to construct and assemble, which may be made i 3 by ordinarymachine shop ,processes, and;

which maybe made at 'a very low-cost.

, v v 7 Further objects are to provide asignaling 1 I 1 switch inwhich a plurality of stationary con-- i ts are arranged in ajcircle about a s ider-i as like mberjprovided with a plurality f movable'contacts adapted to engagethesta- .-tionary contacts, in which a universally mounted movable member is provided whic is adapted to selectively operate any one of the movable contacts to cause such movable contacts to engage or bear against the corre-- sponding stationary contact, and in which there is a slightvsliding contact between the movable contacts and the stationary contacts to thereby keep the contacts clean.

Further objects are to provide a novel form of switch in which a spider spring cooperates to temporarily hold the movable members in any of several predetermined positions to which it may be moved and in neutral or central position.

Further objects are to provide a type of switch, as outlined above, in which a spiderspring and a spider-like contact member are locked to the body portion by a substantially centrally arranged conductor receiving stud or member.

An embodiment of the invention is shown in the accompanying drawings, in which Figure 1 is a vertical sectional view through the switch, such view corresponding to a section on the line 11 of Figure 3.

Figure 2 is a plan view of the switch with parts broken away and in sections.

Figure 3 is a sectional view on the line 3--3 of Figure 1.

Figure 4 is a perspective view showing the switch applied to the' steering columnof automobile. i

The switch comprises a body portion 1. o formedof insulating material such as fibre'or bakelite. This body portion isprovided with a centrally arranged contact stud 2, as shown most clearly in Figure 1, which projects through the body portion and which'is pro- "vided on its lower side with a conductor clamping screw 3. i

The switch is provided with a spider-like contact member 4 which is provided with a plurality of angularly turned arms 5 which terminate in downwardly looped portion 6. The arms 5 and 6 constitute movable contact members as will hereinafter appear. The spider-spring 7 is positioned upon the spiderlike contact member 4 and this spring and the 35 contact member are locked in place by means of the screw 8 passing therethrough and into the center stud 2. j I

It is to be noted that the body portion is provided with an angular cut-out 9 which provides space for a portion of the movable contact members when they are deflected as will hereinafter appear. The body portion is provided with a plurality of stationary contact members 10 which surround the movable contact members and which are locked in place by the studs 11, in the same manner as described in connection with the movable contact members. The lower end of the studs 11 are provided with conductor receiving screws 12.

The body portion carries a plurality of pillars 13 which, in turn, carry a lower socket bearing member 14 and an upper socket bearing member 15. The lower socket bearing member 1a carries a universally mounted member 16 provided with a downwardly projecting portion having an operating head 17 formed of insulating material and of enerally cylindrical contour, although obvlously the shape of this head may vary. The head is preferably provided with flattened faces which engage the movable contact arms or members as shown. The universally mounted member is provided with upwardly projecting stem terminating in a ball 18.

An operating member such as a handle 19 -is provided for operating the switch. This handle is carried by the bearing ball 20, seated within the upper socket 15 and having a lower portion recessed for the reception of the spherical end 18 of the universally mounted member.

It will beseen that the handle is universally mounted and that the head 17 of the lower member moves in the same direction that the handle is moved. For example, if thehandle 19 is rocked to the left as viewed in Figure 1, the head 17 is also rocked to the left. The switch may be provided with any suitable form of easing having a-top 2 1 apertured for the reception of the upper portion of the socket 15 as shown in Figures 1 and 2 and provided with legends 22 (See Fig. 2) to indicate the different circuits controlled by the switch. Preferably the upper portion of the socket 15 is provided with notches or slots'23 (See Fig. 2) which constrain the. handle to move in diflerent predetermined paths arranged at an angle to each other. The number of slots, of course, correspondstothe.

number of paths of stationary and movable contacts.

to this, the arms of the spider spring are spider spring constantly engage the corresponding flattened faces of the head and thus prevent rotation of the head. In addition rounded at their upper ends and are adapted to snap into notches 25 formed in the lower face of the head 17 when the head is rocked laterally into any of its predetermined positions. These spider springs, therefore, cooperate with the head to provide a temporary locking means tending to hold the head in its outermost position whenever the head is moved. This construction, therefore, holds the particular pair of contacts in engagement With each other until the handle is positively moved back to its neutral position.

It is preferable to mount the switch on the steering column of an automobile centrally of the hand wheel 26 as shown in Figure 4 so it will at all times be within easy access of the driver. Obviously the switch can be mounted wherever desired without departing from the spirit of this invention.

It will be seen that a very simple type of signal switch has been provided by this invention which utilizes a universally mounted member controlled in a suitable manner and itself controlling a plurality of pairs of contacts.

It will be seen further that by mounting the movable contacts inde endently of the universally mounted mem or that an extremely simple construction results and one which may be made at a very low cost.

It is to be noted further that there is a slight sliding action between the movable contacts and stationary contacts occurs dur ing closing and opening and consequently the contacts clean themselves and insure a perfeet operation of the switch at all times.

It is to be noted also that the switch has relatively few parts and is of sturdy construction.

Although the invention has been described in considerable detail, it is intended that such description be interpreted as illustrative rather than limiting, as the invention may be variously embodied and is to be interpreted as claimed.
